I suspect this was the case with Dr. Heberden, as it was also with the late Dr. Hunter; of whom Mr. John Hunter observes, that, " though he was extremely accurate in most things, he could never feel that nice distinction in the pulse that many others did, and was ready to suspect more nicety of dis- crimination than can really be found. Frequency of pulsation in a given time is measurable by instruments; smartness or quickness in the stroke, with a pause, is measurable by the touch, but the nicer peculiarities in the pulse are only sensations in the mind. I think," continues this distinguished physiologist, " I have been certain of the pulse having a disagreeable jar in it when others did not per- ceive it, when they were only sensible of its frequency and strength : and it is, perhaps, this jar that is the specific distinction between constitutional disease or irritation and health. Frequency of pulsa- tion may often arise from stimulus, but the stroke will then be soft; yet softness is not to be depended on as a mark of health, it is often a sign of dissolution; but then there must be other attending symp- toms."! Dr. Fordyce's table of the pulse is, perhaps, unnecessarily compli- cated ; but the strength or weakness, fullness or smallness, hardness or softness, regularity or irregularity of the pulse, are indications nearly as clear as its frequency or slowness, and, in many cases, quite as diagnostic of the general nature of the disease. Frequency and slowness of the pulse taken by themselves, indicate little more than the degree of irritability of the heart, or the force of the sti- * Med. Trans. Vol. u. p. 20. tOn Blood, Part. n. Ch. iii. p. 318. 20 PHYSIOLOGICAL PROEM. [CL« 1U' mulus that is operating upon it. The strength and regularity, or weakness and irregularity of the pulse are as palpable to the finger as the preceding signs, and show, in characters nearly as decisive, the degree of vigour or debility of the heart; and hereby, except where this organ is labouring under some local affection, the vigour or debility of the system, which a mere variation in the state of the frequency of the pulse will not tell us. A full a id a small pulse may be distinguished with almost as much ease as any other property it possesses; this Mr. John Hunter ascribes to the state of the arteries: but, if I mistake not, it gives us rather a measure of the quantity of blood circulating through the system, than of the muscular strength of the arteries, or of the heart itself; which is often a very impor- tant indication, and especially when combined with the preceding signs; as it will then be our best guide in cases where we have determined upon emptying the vessels as far as we can do it with- out danger. Hardness and softness of the pulse, together with that vibratory thrill which has been called wireness, are not quite so easily learnt as its fullness and smallness, but a nice finger will readily discriminate them, and practice will point out the difference to ™ery one. These characters Dr. Fordyce makes dependent, and I think with great reason, on the state of the arteries rather than on that of the heart, or on the quantity of the circulating fluid; and Mr. John Hunter concurs in the same view. They measure the degree of vascular tone, or power of resistance ; and when the same effect, whether above or below the natural standard, takes place in the capillary arteries, it produces that change in the pulse which he distinguished by the names of obstruction and freedom, but which it is not always easy to discriminate from several of the preceding qua- lities ; nor is it of great importance, as we have in such cases other symptoms that more strikingly manifest the same fact. Thus far, perhaps, the doctrine of pulsation may be studied to advantage ; but when, beyond this, we come to a distinction between the free and dilated pulse, as proposed also by Dr. Fordyce ; the quick and the frequent, as proposed by Stahl ;* and the dicrotic, coturnizing, and inciduous, proposed by Solano,! as mere sub-varie- ties of the rebounding, or redoubling, itself a variety of the irregu- lar pulse, we perplex pathology with a labyrinth in which the stu- dent is lost, and the master wanders to no purpose. De Bordeu acquired great reputation in the middle of the last cen- tury, for applying the doctrine of pulsation as an index to the dis- eases of every distinct organ of the body ; whence he not only adopted most of the subdivisions of Solano, but added others, and subdivided them still further. He started it as a new hypothesis, which he endeavoured to support by facts and arguments, that every separate organ possesses a principle of life in some measure peculiar to itself, and independent of the rest of the frame ; that each is endowed with a proper function, and susceptible of proper * De Differentia Pulsus ceteris et frequentis. t .Novae Observations circa crisium praedictiones ex pulsu.

III.] PHYSIOLOGICAL PROEM. 21 sensations and movements; and that, by the agreement and co-ope- ration of all these distinctive powers, the life and health of the en- tire system are built up and maintained. These principles are developed and defended in his thesis " De Sensu gerenice conside- rate," published at Montpellier in 1742. Though arrogating the merit of originality, they are, however, little more than a revival of the ancient doctrine of harmony invented by Aristoxenus, and at one time very popular in Greece, as we learn from Lucretius: —Multa quidem sapientum turba putarunt S'nsum auimi ceria. nou esse in parte locatum; Verura habitum quemdam vitalem corporis esse, 'apmoniajt Graiei quam dicunt.* M. de Bordeu, in adopting this hypothesis, supposed farther, that an affection of any particular organ will occasion a peculiar varia- tion in the pulse from its natural state ; and, by a careful attention to these changes, he conceived himself capable of ascertaining the seat of the disease, and the channel through which nature was aim? ing at a crisis. He describes, in consequence, an overwhelming multiplicity of organic pulses; but his general division is into supe- rior and inferior pulses: and this he founds on an observation that the actions of the parts seated above the diaphragm, and of those below, excite very different impressions on the circulatory system. These views are chiefly given in the most famous of all his publica- tions, intitled, " Recherches sur le Pouls par rapport aux crises."! This hypothesis became extremely popular in France and Germany, and excited a considerable degree of attention at Edinburgh. It is now, however, little heard of, and is by no means worth reviving. In effect, a voluminous and complicated classification of pulses is rather a proof of an active fancy than of a sound judgment: and though Dr. Heberden and Dr. Hunter may have thought too lightly of this branch of pathognomy, it is better to adopt their simplicity than the puerile conceits of many more elaborate pulse-makers. The Chinese have a more operose system of pulsations than any that have appeared in Europe ; but nothing can be more whimsical than their divisions. Avicenna treated of the pulse musically; and Hoffenuffer, pursuing his principles, drew up, in 1641, a musical scale of the pulse, dividing it into musical time, and marking the different beats by semibreves, minims, and crotchets, semiquavers, and demisemiquavers; thus reducing his patient to a harpsichord, and his profession to a chapter on ihorough-bass. III. To speak minutely of the constituent principles of the blood, would carry us too far into the regions of animal chemistry; and I / shall hence limit myself to a very brief analysis of those that are fixed or confinable, having already paid some attention to the gasses in the physiological proem to the preceding class. * De Rer. Nat. Lib. in. 90. See the author's examination of this hypothesis, and its resemblance to others of later date, in the notes to his Translation of Lu- cretius.

Parmentier and Deyeux, who ar- ranged them under the following heads:—1. A peculiar aroma, or odour, of which every one must be sensible who has been present at a slaughter-house, on cutting up the fresh bodies of oxen. 2. Fi- brin, or fibrous matter. 3. Gelatine. 4. Albumen. 5. Red colour- ing matter. 6. Iron. 7. Sulphur. 8. Soda. 9." Water. Still minuter and more exact experiments have since been made upon particular portions or the whole of the blood, especially by Dr. Marcet,* Dr. Bostock,! and Professor Berzelius,J which confirm the greater part of the preceding results, but have detected a few errors which it is necessary to notice. Neither the blood of man nor of quadrupeds, so far as they have been examined, contain any gelatine. " The mistake," says M. Brezelius, u arises from the gelatinous appearance of the albu- men ; I have never been able to detect a particle of gelatine in blood, and, as far as my researches extend, 1 have found gelatine to be a substance altogether unknown to the economy of the living body, and to be produced by the action of boiling water on cartilage, skin, and cellular membrane ; substances which are totally distinct from fibrin and albumen." It follows, therefore, that wherever ge- latine is found in the animal frame, it is produced by a decomposi- tion and recombination of the particles of the blood by the action of the secernents. The sulphur detected in the blood by Parmentier and Deyeux does not exist in a free state, but is a component part of its albu- men, as is also its carbone and hydrogene, which, in consequence, have as strong a claim to be considered as constituent principles as sulphur. It is by means of its constituent sulphur that the albumen of blood or of an egg, becomes capable of blackening a silver instru- ment employed to stir it. And as it is the albumen that is now known to dissolve the oxydes of mercury introduced into the blood in the cure of syphilis, it is probably owing to the sulphur of the albumen that this effect is produced; or that the oxydes of any me- tals introduced as medicines into the blood are dissolved; since the albumen of the serum is also discovered to be a powerful menstruum in dissolving iron, copper, and other metallic preparations. The iron traced in the blood is, in like manner, a constituent principle of the red colouring matter, and exists in so intimate an union with it that it cannot be detected by the best re-agents we possess, till the composition of the colouring matter is totally de- stroyed by heat, or some other means. With these explanations we are now able to proceed to a clear comprehension of the following brief analysis of the blood, as cor- rected by the later experiments of M. Berzelius, supported by those I have just adverted to, of Dr. Marcet and Dr. Bostock. • * Trans. Medico-Chirurg. Soc. Vol. n. p. 370. t Id. Vol. i. |Id. Vol. in. CL. III.] PHYSIOLOGICAL PROEM. 23 Blood is composed of two parts, one homogeneous and liquid, and one only suspended in the liquor, and spontaneously separating from it when at rest. The homogeneous and liquid part consists of much albumen and a little fibrin, both combined with soda, and all dissolved in water. It also contains a small portion of a few other saline and animal sub- stances. The suspended part consists of the colouring matter. It differs from albumen chiefly in its colour and its insolubility in serum. Iron enters as a constituent ingredient into this material, in the pro- portion of 3^ of its weight. It seems to be the colouring princi- ple ; but cannot be separated from it as long as it continues to be colouring matter. This separation can only be effected by combus- tion, or by the concentrated acids, both of which agents entirely de- compose the substance with which the metal is combined. The iron exists in the form of oxyde, with a small proportion of sub- phosphate of the same. But the colouring matter cannot be arti- ficially produced by uniting albumen with red subphosphate of iron. Fibrin, albumen, and colouring matter, resemble each other so closely, that they may be considered as modifications of one and the same substance. Each of these three substances yields, when decom- posed, but does not contain, earthy phosphates and carbonate of lime ; for the entire blood holds in solution no earthy phosphate, except, perhaps, in too small a quantity to be detected. From these earths it is clear that the bones derive their earthy supply; which, however, it is also clear they can only do, as in the case of the formation of gelatine, inconsequence of a decomposition of the blood as it arrives at the secernents of the bones. Vauquelin endeavoured to separate the colouring matter from the blood by means of sulphuric acid ; but this material is not wanted, and does not very well answer the purpose. A method proposed by M. Berzelius in another communication is much simpler as well as more effective * It consists in placing the clot or coagulum of blood upon blotting paper, to get rid of the serum as completely as possible. The clot is then to be put into water, in which the co- louring matter dissolves, while the fibrin remains unaffected; when the water being evaporated, the colouring matter is obtained in a separate, state. On reducing this matter to ashes, about T}^ of iron can always be separated. It is difficult to determine by what means the iron, or the sul- phur, or the elementary principles of calcareous earth, obtain an existence in the blood. If these materials were equally diffused throughout the surface of the earth, we might easily conceive that they are introduced through the medium of food. But as this is not the case; as some regions, like New South Wales, at least on this side the Blue mountains, contain nolime-stone whatever, and others * Ann. de Chhn. et de Phys. V. 42. 24 PHYSIOLOGICAL PROEM. [CL. III. no iron or sulphur, while all these are capable of being obtained apparently as freely from the blood of the inhabitants of such re- gions, as from that of those who live in quarters where such mate- rials enter largely into the natural products of the soil; it is per- haps most reasonable to conclude that they are generated in the laboratory of the animal system itself, by the all-controlling influ- ence of the living principle. What may be the aggregate quantity of any of these minerals in the mass of blood belonging to an adult, has not been determined with accuracy. The amount of the iron has been calculated by Parmentier and Deyeux, upon grounds furnished them by Menghini, at seventy scruples, or very nearly three ounces, estimating the average of blood in the vessels of an adult at twenty-four pounds, which is most probably something short of the mark. Whether iron exists in any other part of the animal frame than the colouring matter of the blood, is in some degree doubtful. Vauquelin seems to have traced it in egg-shells and oyster-shells ; and Mr. Brande thinks he has done the same in the chyle and in the serum, and this as largely as in the colouring matter of the blood, which, after all, he thinks cohtains only a very minute quantity.* But these experiments are too indefinite, and by no means coincide with those of Berzelius, since confirmed by other chemists If the experiments of Menghini may be relied upon, human blood contains a larger proportion of iron than that of quadrupeds; quadrupeds have more than fishes, and fishes more than birds. But though there can be no longer any question of the existence of iron as a constituent principle in the blood, we are in total igno- rance of the part it is intended to perform. It is, perhaps, the co- louring material, though, as I have already observed in the physio- logical proem to the preceding class, even here we are still very much in the dark, and are overwhelmed with contending hypo- theses. It is probable that the red particles of the blood contribute to the strength of animals to whom they are natural, as conjectured by Mr. J. Hunter, and that the strength of such animals is in pro- portion, or nearly so, to their number. Yet such particles are never found in the blood of several classes of animals, as insects and worms: and in those in which they are found, they have often no existence in the commencement of life ; for they are not disco- verable in the egg of ihe chick, when the heart first begins to pul- sate ; nor are they, in any animals, pushed into the extreme ar- teries, where we must suppose the serum reaches. And hence. whatever their value, they cannot be "regarded as the most impor- tant part of the blood, or as chiefly contributing to the growth aud repair of the system.! Various attempts have at different times been made, to determine the form and measure the diameter of the corpuscles of the blood. but even this does not seem to have been accompanied with ven great success. Delia Torre, by applying his microscope, detected * Phil. Trans. 1812 n. 112. t On Blood, p. 46. •". CL. 171.] PHYSIOLOGICAL PROEM. 25 them, as he thought, to be flat circles or rings with a perforation in the centre; and "Mr. Hewson ascribed to them the same shape, but represented them as hollow or vesicular, with a dot of red colour- ing matter in the centre instead of a perforation; so that, if his de- scription could have been substantiated, they might literally have been regarded as the wheels of life moving on iron axles. Mr. Hewson's hypothesis, however, extended much farther; for, by a variety of plausible experiments, he persuaded himself, and many others also, that it is the office of the thymus and lymphatic glands to secrete and elaborate these vesicles which are then carried by the lymphatics and thoracic duct to the arteries, and from the arte- ries to the spleen which furnishes them with their coloured axles. These physiological and microscopic fancies, however, have been long overturned; and the general shape of the corpuscles has been sufficiently proved to be globular, the diameter of which, as mea- sured by the microscopical experiments of M. Bauer, is 5^Vff part of an inch; a dimension, however, which has since been reduced by Captain Kater to ToVo~ Par* °^ an inch-* M. Bauer has also as- certained, as he thinks, that it is not the centre of the globule that is dotted, but its outline that is surrounded with colouring matter; so that, instead of being annular wheels with iron axles, they are sphe- rular wheels with iron tiers. It does not seem that the microscope has added much that can be depended upon to our knowledge upon this subject. We have also still much to learn, not merely in respect to the real difference between human blood and that of quadrupeds, but the real difference between that of any one species of animal and any other. M. Berzelius observes, that " the great agreement in the composition of human and ox blood is remarkable, and explains to us the possibility of the phaeoomena observed in the experiments in transfusion." But we have a clear proof that the blood of one species of animals differs so much from that of another, either in its principles or their modification, that no benefit can result from transfusion, unless from like kinds to like kinds. Thus, according to several interesting experiments of Dr. Blundell, a dog, asphyxi- ated by hemorrhage, may easily be recovered by a transfusion of blood from another dog, but is little or not at all relieved if the blood be taken from man.! Upon the whole, however, we cannot but regard the blood as in many respects the most important fluid of the animal machine : from it all the solids are derived and nourished, and all the other fluids are secreted; and it is hence the basis or common pabulum of every part. And as it is the source of general health, so it is al- so of general disease. In inflammation it takes a considerable share, and evinces a peculiar appearance. The miasms of fevers and ex- anthems, are harmless to every other part of the system, and only become mischievous when they reach the blood: and emetic tartar, * Phil.

III. when introduced into the jugular vein, will vomit in one or two minutes, although it might require, perhaps, half an hour if thrown into the stomach, and in fact does not vomit till it has reached the circulation. And the same is true of opium, jalap, and most of the poisons, animal, mineral, and vegetable. If imperfectly elaborated, or with a disproportion of some of its constituent principles to the rest, the whole system partakes of the evil, and a dysthesis or mor- bid habit is the certain consequence ; whence tabes, atrophy, scur- vy, and various species of gangrene. And if it become once im- pregnated with a peculiar taint, it is wonderful to remark the te- nacity with which it retains it, though often in a state of dormancy or inactivity, for years or even entire generations. For as every germ and fibre of every other part is formed and regenerated from the blood, there is no other part of the system that we can so well look to as the seat of such taints, or the predisposing cause of the disor- ders I am now alluding to; often corporeal, as gout, struma, phthsis ; sometimes mental, as madness, and occasionally both, as cretinism. It is hence the blood has been supposed to be alive : a belief of very high antiquity, and which has been warmly embraced by Dr. Harvey and many others of the first physiologists of modern times. It was a favourite opinion of Mr. John Hunter, and runs through the whole of his doctrines. " That the blood," says he, " has life, is an opinion 1 have started above thirty years, and have taught it for near twenty of that time in my lectures. It does not, therefore, come out at present as a new doctrine; but has had time to meet with considerable opposition, and acquire its advocates. To con- ceive that blood is endowed with life while circulating, is, perhaps, carrying the imagination as far as it well can go ; but the difficulty arises merely from its being a fluid, the mind not being accustomed to the idea of a living fluid."* The experiments and train of reasoning he urges in favour of this opinion are highly ingenious and peculiarly strong. And, though they may not be demonstrative of a vital and energetic essence separate from the blood itself, but inherent in its substance, and con- troling its motions, they seem very clearly to show that the blood is endowed with peculiar powers; and that, as matter at large is subject to the laws of gravitation, so the matter of the blood is sub- ject to the laws of instinct. We may here add, in favour of Mr. Hunter's opinion, the following two corollaries of Dr. Philip, de- duced from a large field of experiments. lt The power of the blood- vessels, like that of the heart, is independent of the nervous system. — The blood-vessels can support the motion of the blood after the heart is removed."! Admitting these deductions to be established, the power here re- ferred to, and capable of influencing the blood or the blood-vessels, separately from that of the heart, and of the nervous system, must be the power of simple life, or of instinct, which is simple life ope- rating by the exercise of its own laws. * On Blood, p. 77. t Phil.

There is no complaint so common as fever; none in which mankind, whether professional or laical, are so little likely to be mistaken, and yet none so difficult to be defined. In reality no writer seems to have been fully satisfied with his own definition; and it is not extraordinary, therefore, that he should seldom have given satisfac- tion to others. The difficulty proceeds from the complexity of the symptoms that enter into the character of a fever ; the contrariety of many of them to each other in different stages of it; and the oc- casional absence of some that, in other instances, appear to consti- tute its leading features. There are also two other difficulties of considerable magnitude that the nosologist has to contend with in laying down a clear and perspicuous survey of fevers ; and that is, their division or colloca- tion, and their generic names. But as I have already pointed out these difficulties, and the means by which they are attempted to be remedied under the present arrangement and nomenclature, in the running commentary to the order before us in the volume of Noso- logy, 1 shall beg to refer the reader to the observations there laid down, and shall subjoin only one or two additional remarks upon the same subject. Although the number of the pulse as well as the heat is preter- naturally augmented in almost every case of fever, an extraordinary instance is sometimes to be met with that opposes the general law, for the most part dependent, I believe, on a great and sudden op- pression of the brain; an explanation which withdraws the anomaly, and accounts for the ordinary increase of pulsation as soon as such 28 HJEMATICA. [CL. IH.~OR. I« oppression is removed. Thus, in the yellow fever of Antigua in 1816, the pulse, as Dr. Musgrave infoms us, was, in one instance, under forty-four. " We almost fancied," says he, "this unusual softness might be constitutional: but, on opening a vein, it greatly increased in frequency; and, after the loss of a considerable quantity of blood, it numbered eighty, with nearly complete relief from every uneasy sensation."* # In such cases the heat of the system usually exhibits as little fe- brile augmentation as the pulse : for as the former is the result oi increased action, till such increased action takes place, the heat, as in the first stage of the paroxysm, may continue even below the natural standard. There is a still more curious variation from the general law, which is sometimes, though very rarely, found to take place, of which Schenck gives a single example that occurred in his own practice ; I mean, a reversed order of the symptoms of the febrile paroxysm, and an appearance of the sweating stage before the shivering and hot fit ! To provide for these extraordinary and anomalous incidents by any definition whatever, is beyond the power of language. They must be left to themselves, and will rather confirm than disturb the definition now offered, agreeably to the maxim of the Schools— exceptio probat regulam. In dividing fevers into distinct genera, I have taken the line of demarcation from the character of their duration, as limited to a single paroxysm ; as composed of numerous paroxysms, with inter- vals of intermission or perfect apyrexy ; as composed of numerous exacerbations, with intervals of remission, or imperfect apyrexy j and as composed of a single series of increase and decrease, with a mere tendency to intervals of remission, without perfect apyrexy at any time. Other nomologists have drawn their generic distinctions from other circumstances; as their disposition or indisposition to. putridity ; their inclination to a sporadic or an epidemic character; the vigour and violence, or weakness and debility of their action; or, in the language of Dr. Darwin, the nature of their influence on the sensitive or irritative fibres of the animal frame. The most obvious mark, however, and that which has been most generally approved, is the character of duration assumed in the arrangement before us. To all the rest there are greater or less objections* which, as I have already examined them in the comment just refer- red to, need not be repeated ia the present place. Regulated, therefore, by the principle before us, fever admits of the four following genera :— I. EPHEMERA. DIARY FEVER. IK ANETUS INTERMITTENT FEVER. HI. EPANETUS. REMITTENT FEVER. IV. ENECIA.

I.J SANGUINEOUS FUNCTION. 29 To each of these belong several species, and to most of the spe- cies several varieties, as will be noticed in their respective order. Some slight deviation from the ordinary nomenclature may be observed in the generic names above : but the reader can have no difficulty upon this head, as he will find the changes that have herely been occasioned are in every instance founded upon a principle of correctness and simplification ; and consequently calculated to dis- entangle rather than to add to his incumbrances, and to facilitate hia progress in the labyrinth before him. The term Ephemera, is, indeed, well known to every one. Anetus and Epanetus are Creek terms, importing intermittent and remittent, from xvir,pt and tirxmy-t. Enecia, from the same tongue, denotes continued action, and is a derivation from »)»««»)$. Before, however, we enter upon the practical part of this subject, it appears necessary to make a few remarks upon one or two other questions that have very largely occupied the attention of many pathologists, and especially concerning the proximate and remote causes of fever; and the tendency which fever has been supposed to evince of terminating suddenly, either favourably or unfavourably, at fixed periods of its progress. Proximate and remote causes are rather terms of recent than of ancient writers. In early times the causes of diseases chiefly con- templated were its proegumenal or predisponent, and its procat.rc- tic or occasional. Thus, an hereditary taint, or habitual indulgence in high living, may be regarded as a proegumenal cause of gout; and catching cold, or an unusual exertion of muscular exercise, may form its procatarctic cause: both of which are absolutely necessary; for it is clear that the latter, without the former, would not produce the disease ; and it is just as clear that the former might remain harmless in the constitution for years, were it not to meet with the co-operation of the latter, which is often, on this account, denomi- nated an exciting cause. Generally speaking, the first was regarded as an internal, and the second as an external cause ; and in the in- stance selected they are so ; but they are not so always. To be acquainted with causes of this kind is always useful; and, in guarding against the approach of diseases, it is often of the utmost importance : but they give us very little information upon the real nature of diseases, and the mode of managing them when present. And hence another set of causes have been adverted to, and have of late been chiefly studied, and particularly in" the case oi' lever. " That only," says Gaubius, " deserves the name of a physical cause which so constitutes the disease, that, when present, the disease exists; while it continues, the disease continues ; when changed or removed, the disease is altered or destroyed." It is this which con- stitutes the proximate cause, and is, in fact, the essence of the dis- ease,, the actual source of all its effects. The remote cause is that which directly produces the proximate ; as a specific virus in sy- philis, or a specific miasm in influenza, or epid. mic catarrh. In fever we can often trace the remote causes; though we are so H^MATICA. [CL. I1I.-OR. I. still too little acquainted with the nature of several of them to be able to restrict them to a specific mode of action; of the proximate cause, we know but very little at present, and it will probably be long before we shall know much more. Let us, however, begin with the pkoximate cause as that which has most excited the attention of physicians in all ages. Upon this sub- ject, indeed, a great deal of learned dust has been raised, and a great deal of valuable time consumed Ancient speculations, for they are not entitled to the name of theories, have been overthrown ; and modern speculations, in vast abundance, erected upon their ruins; which, in rapid succession, have also had their day and ex- pired. It is an inquiry, therefore, not likely to prove very pro- ductive ; yet, as forming a part of medical science of which no stu- dent should be altogether ignorant, it seems necessary to extend it to a brief survey of the most popular doctrines which have been advanced upon the subject in different ages. Fevers then, in respect to their proximate cause, have been con- jectured to originate from a morbid change, either in the composi- tion of the blood, or in the tone or power of the living fibre. The first view has given rise to various hypotheses, that rank under the common division of the humoral pathology. The second has given rise to other hypotheses appertaining to the common division of the FIBROUS Or NERVOUS PATHOLOGY. The hypotheses derived from the one or the other of these sources, that are chiefly entitled to attention, are the following: of which the first two belong to the former division, and the remain- der to the latter. I. That of the Greek schools, founded on the doctrine of a con- coction and critical evacuation of morbific matter. II. That of Boerhaave, founded on the doctrine of a peculiar vis- cosity, or lentor of the blood. HI. That of Stahl, Hoffman, and Cullen, founded on the doctrine of a spasm on the extremities of the solidum vivum, or living fibre. IV. That of Brown and Darwin, founded on the doctrine of accu- mulated and exhausted excitability, or sensorial power. V. To which we may add that fevers have, by some physiologists as Dr. Clutterbuck, and Professor Marcus, been identified with in- flammation ; and their proximate cause been ascribed to increased action in some particular organ. 1. It was the opiiion of Hippocrates that fever is an effort of na- ture to expel something hurtful from the body, either ingenerated or introduced from without. Beholding a violent commotion in the system, followed by an evacuation from the skin and kidneys, with which the paroxysm terminated, he ascribed the commotion to a fermentation, concoction, or ebullition, by which the noxious matter was separated from the sound humours ; and the evacuation to a despumation or scum which such separation produced, or rather to the discharge of this morbid scum from the emunctories that open externally. Galen supported this view with all the medical learn- CL. IH.tOR. I.] SANGUINEOUS FUNCTION. 31 ing of his day; and it is the only explanation of fever to be met with in medical writings, through the long course of three thousand years ; in fact, till the time of Sydenham, who still adhered to it, and whose pages are full of the language to which it naturally gave birth. It blended itself almost insensibly with the language of the che- mists of the day, notwithstanding the professed hatred of Paracelsus and Van Helmont towards the whole range of Galenic doctrines, and the solemn pomp with which the former had condemned and burnt the entire works of Hippocrates and Galen. And hence, under the influence of chemistry, at this time assuming a soberer aspect, the supposed animal despumation was contemplated as possessed according to different circumstances, of different chemi- cal qualities and characters; and particularly as being acid, alkaline, effervescent, or charged with some other acrimonious principle, too highly exalted, or in too great a proportion. This doctrine, considered merely hypothetically, is not only inno- cent, but highly ingenious and plausible. It is in unison with seve- ral of the phenomena of pyrectic diseases; and derives a strong collateral support from the general history of exanthems or eruptive fevers, in which we actually see a peccant matter, producing gene- ral commotion, multiplying itself as a ferment, and at length sepa- rated and thrown off at the surface by a direct depuration of the system. So far therefore as relates to exanthems, the opinion is sufficiently correct. But the moment it is brought forward as the proximate cause of fever properly so called, in which there is no specific eruption, it completely fails. For first, no explanation is here given as to the means by which any such concoction or fermentation, or multiplication of morbific matter in any way takes place. Next, there are many fevers pro- duced evidently by cold, fear, and other excitements, as well mental as corporeal, in which most certainly there is no morbific matter introduced, and wherein we have no reason to conceive there is any generated internally ; while the disease, limited perhaps to a single paroxysm, closes nevertheless with an evacuation from the skin or the kidneys. And, thirdly, we sometimes behold fevers suddenly cured, as Dr. Cullen jj.as observed, by a hemorrhage so moderate, as for example a few drops of blood from the nose, as to be incapable of carrying out any considerable portion of a matter diffused over the whole mass of the blood; while we are equally incapable of con- ceiving how such diffused morbific matter could collect itself at a focal point, or pass off at a single outlet: or of tracing in the dis- charge, after the minutest examination, any properties different from those of blood in a state of full health. I have observed that this hypothesis is, however, harmless enough when merely brought forward as a speculation. But it has not al- ways been limited to this point; for it has occasionally been advan- ced as a practical and efficient principle; and the febrile commotion. 32 HvEMATICA. [CL. HI.-OR. t. and particularly the hot fit, has, in treating the disease, been pur- posely increased, with a view of assisting nature in her curious but unknown process of expelling the peccant material; and the most dangerous consequences have followed. II. The acute and penetrating mind of Boerhaave, who was born in 1668, was sufficiently sensible of this danger; and the discoveries which were now taking place in chemistry and physiology, led him progressively to the construction of a new theory, which in a tew years became so popular as to obtain a complete triumph over that of the Greek Schools. Leeuwenhoeck, by a delicate and indefatigable application of the microscope to animals of a transparent skin, had endeavoured to es- tablish it as a fact, that the constituent principles of the blood con- sist of globular corpuscles; but that these corpuscles differ in size in a regular descending series according to the constituent principles themselves ; and that each set of principles has its peculiar blood- vessels, possessing a diameter just large enough to admit the glo- bules that belong to it, and consequently incapable, without force, of allowing an entrance of those of a larger magnitude; and hence that the blood vessels possess a descending series as well as the par- ticles of the blood. It was upon this supposed fact, that Boerhaave built his hypothe- sis. He conceived that almost all diseases may be resolved into an introduction of any given series of particles of blood into a series of vessels to which they do not properly belong; and he distinguished such introduction by the name of error loci. He conceived still far- ther, that this heterogeneous admixture is very frequently taking place ; and that its chief cause consists in a disproportion of one or more sets of the sanguineous principles to the rest, by which their globular form is occasionally broken down and destroyed, and ren- dered either too thin and serous, or too gross and viscid. The vis- cidity of the blood he distinguished by the name of lentor ; and to a prevalence of this lentor, or viscidity, he ascribed the existence of fever; maintaining that the general disturbance which constitutes fever proceeds from an error loci of the viscid blood, whose gross- er corpuscles, from their undue momentum as well as superabundance, press forcibly into improper series of vessels, and stagnate in the extremities of the capillaries whence the origin ofjlhe cold stao-e and consequently of the stages that succeed it, to which the cold stage gives rise ;* and hence those medicines which were supposed capable of dissolving that tenacity, or breaking down the coales- cence of such a state of the blood, were denominated diluents hd- mectants, and attenuants, whilst those of an opposite character were called inspissants : terms which have desceuded to our own day, and are still retained even by those who pay little attention to the hypothesis that gave them birth. The system of Boerhaave, therefore, consisted of an elegant and * Aph. 756. Comment Van Swiet. Tom. h. p. 528. Edit. Lugd. Bat. 40. 1745. CL. III.-OR. I.] SANGUINEOUS FUNCTION. 33 artful combination of both the earlier and later doctrines of corpus- cular physiology. Without deserting the humoral temperaments of Galen, or the constituent elements and elective attractions of the al- chemists, he availed himself of the favourite notions of the corpuscu- lar pathologists, their points or stimuli, their frictions, angles, and spherules, derived from the Cartesian philosophy, which were now exercising as triumphant a sway over the animal, as over the material system; and interwove the whole into an eclectic scheme, so plau- sible and conciliatory to all parties, that all parties insensibly felt themselves at home upon it, and adopted it with a ready assent, rn the emphatical language of M. Q,uesnay, it was u la medicine col- lective." The most triumphant fact in favour of the Boerhaavian hypothe- sis is that the crust on the blood in inflammations, and cauma or inflammatory fever is often found peculiarly dense. But as fevers (and certainly the greater number) are found without any such crust; and as a similar crust, though perhaps, not quite so dense, exists under other and very different states of body, as in pregnancy and scurvy (porphyra), even this leading appeal has long lost its power of conviction : whilst the abruptness with which fevers make their as- sault, from sudden occasional causes and in constitutions of every diversity, forbid the supposition that in such cases a lentor or sizy crasis of the blood, and especially a glutinosum sponlaneum can have time to be produced, however it may exist occasionally, and be perhaps the source of other disorders. III. To this period of time, in the production of fever, and indeed of all other diseases, the human body was regarded as almost en- tirely passive, a mere organic machine, operated indeed upon by some autocrateia, as nature, or a vis medicatrix, but in the same manner as other machines, and mostly by similar laws. Its mus- cles were contemplated as mechanical levers, and its vessels as hy- draulic tubes, whose powers were calculated upon the common principles of mechanics and hydronamics; and were only supposed to be interfered with by the internal changes perpetually taking place in the fluids they had to convey. A new era, however, at length began to dawn upon the world: a more comprehensive spirit to pervade medical study: the animal frame was allowed to exhibit pretensions superior to the inanimate, and not only to be governed by powers of its own, but by powers which are continual- ly and systematically from a given point operating to a preserva- tion of health where it exists, and to a restoration of health where it has been lost or injurecl. Stahl, who was contemporary with Boerhaave, and in the university of Halle in 1694, first started this loftier and more luminous idea,—more luminous, though the light was still struggling with darkness; made the mind the controlling principle, and the solidum vivum, or nervous system, the means by which it acted. Fever, on his hypothesis, consisted in a constric- tive or tonic spasm, in his own language spasmus tonicus, produced by a torpor or inertness of the brain, at the extremity of the nerves. von. n. ^ 34 HjEMA'IICA. [CL. IH--OR- '• and counteracted by the remedial exertions of the mind, the v|re9 medicatrices of his hypothesis, labouring to throw off the assailing power; whence the general struggle and commotion by which the febrile paroxysm is characterized. Hoffman, who was a colleague of Stahl, took advantage of this new view; followed up the crude and primary ideas of Stahl with much patient and laborious investi- gation ; and soon presented to the world a more correct system, in a more attractive style; but apparently with a disingenuous con- cealment of the source from which he had borrowed his first hints. He omitted the metaphysical part of the Stahlian hypothesis, took from the mind the conservative and remedial power over the dif- ferent organs with which Stahl had so absurdly endowed it; seated this power as a law of life in the general organization ; separated the nervous from the muscular fibres, the latter of which were re- garded as only the extremities of the former by Stahl; allowed a wider range and longer term to the constrictive spasm of fever; and changed its name from spasmus tonicus to spasmus periphericus :* giving also to the moving power of the muscular or irritable fibres the name of vis insita, as that of the nervous fibre was called vis nervea. It is highly to the credit of Boerhaave, that his mind, in the lat- ter part of his life, was so fully open to the merits of this hypothe- sis, that he admitted the agency of the nervous power, though a doctrine that struck at the root of his own system, of which we have a clear proof in the change which occurs in the fourth edition of his Aphorisms, and particularly aphorism 755, where he lays down the proximate cause of intermitting fevers. Hitherto it had run thus " unde post accuratum examen totius historiae intermittentium causa proxima constituitur viscositas liquidi arteriosi." But to this, in the edition before us, is added the following: " forte et nervosi (liquidi) tam cerebri, quam cerebelli cordi destinati, inertia."! It is also equally creditable to the learned Gaubius, that, though strongly attached to the Boerhaavian school, in which he was edu- cated, and a zealous contender for many of its doctrines, his under- standing was alike open to the clearer and simpler views of the chemists of the day, upon various points not yet generally adopted and allowed him to become a more thorough convert to their philo- sophy. The reader may judge of this change in his mind by the following passage : " An et naturae humanae facultas inest, moleculas acris detritas aut intropressas angulis, in sphaerulas tornando, blandi- tium creandi ? Non satis constat speciosam ideam aequaliter in flui- dam solidamque acrimoniam quadrare.—Credibilius profecto mix- tione chemica magis quam mechanica rotundatione, id opus per- fici.1"!

I.] SANGUINEOUS FUNCTION. 35 of medicine, that neither the laws of animal chemistry nor of the living fibre had been sufficiently studied for the purposes of a cor- rect pathology : in proof of which it may be sufficient to refer to various articles oh both subjects, inserted in the Ephemerides Na- turae Curiosorum, published at Frankfort, in 1684 ; and the writings of Baglivi,* and Dr. Willis;! and still more particularly to Dr. Gil- christ's elaborate treatise on nervous fevers, inserted in the Edin- burgh Medical Transactions jj in which last the author, following up the hint thrown out by Boerhaave in the aphorism just quoted, endeavours to show how well the two ideas of lentor and spasm are disposed to amalgamate in forming the proximate cause of fever; the spasm consisting of an universal muscular tension, and the len- tor being united according to the nature of the case with inflamma- tion, acrimony, or both; and hence often producing what he de- nominates an alternate nisus and re-nisus. The materials, however, were now becoming too unwieldy; and the wheels of the machine were clogged by the very forces that were designed to increase its motion. Dr. Cullen was well aware of this, and boldly ventured upon a new attempt for the purpose of simpli- fying and facilitating its progress. As his basis he took the hypo- thesis of Stahl as modified and improved by Hoffman: and on this basis erected his stately and elaborate structure, so well known to the medical world, full of ingenuity and daring genius, and which, if it be at this moment crumbling into decay, certainly is not falling prostrate before any fabric of more substantial materials or more elegant architecture. Dr. Cullen has been accused of the same want of ingenuousness towards Hoffman, as Hoffman is chargeable with towards Stahl; and of having introduced his system to the public with little or no acknowledgment of the sources from which he has drawn. But surely no one can bring forward such an accusation, who has read with any degree of attention the preface to his Prac- tice of Physic, in which-he gives a full account of Dr. Hoffman's system in his own words, and pays complete homage to his merits. According to the more elaborated principles of the Cullenian system, the human body is a congeries of organs regulated by the laws not of inanimate matter, but of life, and superintended by a mobile and conservative power or energy, seated in the brain, but distinct from the mind or soul; acting wisely but necessarily, for the general health ; correcting deviations, and supplying defects, not from a knowledge and choice of the means, but by a pre-establish- ed relation between the changes produced, and the motions requir- ed for the restoration of health ; and operating therefore, through the medium of the moving fibres, upon whose healthy or unhealthy state depends the health or unhealthiness of the general frame : which fibres, he regarded with Stahl, as simple nerves, the muscu- * Specimen de fibra motrici et moiboso. t Pathologia Cerebri ct Nervorum. t Vol. iv.

The brain therefore, upon this hypothesis, is the primum mobile, but it closely associates in its action with the heart, the stomach, and the extreme vessels. The force of the heart gives extension to the arteries, and the growth of the body depends upon such ex- tension in conjunction with the nutritious fluid furnished by the brain, and deposited by the nerves in the interstices of their own fibres; the matter of which fibres is a solid of a peculiar kind, whose parts are united by chemical attraction. All nervous power com- mences in the enc^phalon ; it " consists in a motion beginning in the brain and propagated from thence into the moving fibres, in which a contraction is to be produced. The power by which this motion is propagated, we name," says Dr. Cullen, " the Energy of the brain ; and we therefore consider every modification of the mo- tions produced, as modifications of that energy."* He further lays it down as a law of the economy, that the energy of the brain is altarnately excited and collapsed, since every fibrous contraction is succeeded by a relaxation: whence spasms and convulsions are mot* abnormes, and consist in an irregularity of such alternation. But we must distinguish in this system between the energy of the brain and the vital fluid it sends forth by the nerves ; for while the former rises and sinks alternately, the latter remains permanently the same. It is not a secretion, but an inherent principle, never ex- hausted, and that never needs renewal.! nJ^f ,h7P°hthesis' jn ** vari0«s ramifications, influenced every ETJV hlsftheory °f medicine, and consequently laid a foundation for his doctrine of fever The proximate cause of fever was, Z his opinion a collapse or declination of the energy of the brain pro" duced by the application of certain sedative powers, as con agion miasm cold, and fear, which constitute the remote'cau'esThS diminished energy extends its influence over the whole system and occasions an universal debility ; but chiefly over the exTrem^'ves SpoTedttonlf- S *"" * ^ ta ^ *- thf^oTdfitl « Such however," to adopt the words of Dr. Cullen himself «is tctastrihih:oaThTseCODry'that ^ debi'%Pr^fan in- direct stimulus to the sanguiferous system ; whence by the inter of thA°/ i G T1?

I.] SANGUINEOUS FUNCTION. 37 This relaxed or perspiratory section of the paroxysm, however, is not regarded by Dr. Cullen as a part of the disease, but as the prelude to returning health. Yet the fit still consists of three stages; the first of debility or diminished energy, the second of spasm, and the third of heat. And though Dr. Cullen had some doubts whether the remote causes of fever might not produce the spasm as well as the atony of the nervous system, yet he inclined to ascribe the second stage to the operation of the first, as he did most decidedly the third to that of the second: and thus to regard the whole as a regular series of actions, employed by the vis medicatrix naturae for the recovery of health. That fever in its commencement or earliest stage is characteriz- ed by debility of the iiving fibre, or, more closely in the words of Dr. Cullen, by diminished energy of the brain, extending directly or indirectly to the voluntary muscles and capillaries, cannot for a moment be doubted by any one who accurately watches its pheno- mena. And thus far the Cullenian hypothesis is unquestionably correct; as it appears to be also in supposing the cold stage to be the foundation of" the hot, and of the excretion of swe^ by which the hot stage is succeeded. But it fails in the two following impor- tant points, without noticing a few others of smaller consequence. The spasm on the minute vessels produced by debility takes the lead in the general assault; and, though it forms only a link in the remedial process, is the most formidable enemy to be subdued; and hence all that follows in the paroxysm is an effort of the system to overcome this spasm. The effort at length proves successful: the debility yields to returning strength ; the spasm is conquered, and the war should seem to be over. But this is not the fact: the war continues notwithstanding; there is nothing more than a hollow truce; debility and spasm take the field again, and other battles re- main to be fought. There is nothing in this hypothesis to account for a return of debility and spasm, after they have been subdued; nor to show why spasm should ever in the first instance be a result of debility. " In this system," says Dr. Parr, " the production of spasm by debility, is an isolated fact without a support; and the in- troduction of the vires medicatrices naturae, is the interposition of a divinity in an epic, when no probable resource is at hanA" The next striking defect that must occur to the attentive reader is, that debility is here made a cause of strength ; the weakened action of the first stage giving rise to the increased action and re- excited energy that restore the system to a balance of health : and here again we stand in need of the interposition of some present divinity to accomplish such an effort by such means. IV. It is not, therefore, to be wondered at that this system, with all its ingenuity and masterly combination, should not have proved satisfactory to every one. In reality, it did not for many years prove satisfactory to every one in the celebrated sphool in which it was first propounded. And hence, under the plastic hands of Dr. Brown arose another hypothesis, of which I shall proceed to give a 38 I-LEMAT1CA. [CL. lll.-OR. I. very brief outline, together with the modification it received under the finishing strokes of Dr. Darwin. Dr. Brown, who was at first a teacher of the classics at Edinburgh, and a translator of inaugural theses into Latin, commenced the study of medicine about the middle of life, by a permission to attend the medical schools gratuitously. He was at first strongly attached to Dr. Cullen and Dr. Cullen's system ; but an altercation ensued, and he felt an equal animosity towards both. A new and opposite sys- tem, if so it may be called, was in consequence manufactured and publicly propounded in a variety of ways. It had great simplicity of principle, and some plausibility of feature; it attracted the curi- ous by its novelty, the indolent by its facility, and every one by the boldness of its speculations. It circulated widely, and soon acquired popularity abroad as well as at home. Man, according to Dr. Brown, is an organized machine, endowed with a principle of excitability, or predisposition to excitement, by means of a great variety of stimuli both external and internal, some of which are perpetually acting upon the machine; and hence the excitement which constitutes the life of the machine is main- tained. Excitability, therefore, is the nervous energy of Dr. Cul- len ; and, like that, is constantly varying in its accumulation and exhaustion ; yet like the nervous energy of Dr. Cullen, under the direction and guidance of a vis conservatrix et medicatrix naturae distinct from the matter of the organization itself, but pas- sively exposed to the effect of such stimuli as it may chance to meet with, and necessarily yielding to their influence. Upon this hypothesis, excitement is the vital flame, excitability the portion of fuel allotted to every man at his birth, and which, vary- ing in every individual, is to serve him without any addition for the whole of his existence : while the stimuli by which we are surround- ed, are the different kinds of blasts by which the flame is kept up. If the fuel or excitability be made the most of, by a due tempera- ture or mean rate of blasts or stimuli, the flame or excitement may be maintained for sixty or seventy years. But its power of support- ing a protracted flame may be weakened by having the blast either too high or too low. If too high, the fuel or excitability will, from the viohjcce of the flame, be destroyed rapidly, and its power of prolonging the flame be weakened directly; and to this state of the machine Dr. Brown gave the name of indirect debility, or exhaust- ed excitability. If the blasts or stimuli be below the mean rate, the fuel, indeed, will be but little expended, but it will become drier and more inflammable ; and its power of prolonging the flame will be still more curtailed than in the former case ; for half the blast that would be required to excite rapid destruction antecedently will be sufficient to excite the same effect now. This state of the machine, therefore, the author of the hypothesis contra-distinguish- ed by the name o/ direct debility, or accumulated excitability. Upon these principles he founded the character and mode of treat- ment of all diseases. They consist but of two families, to which he gave the name of sthenic and asthenic j the former produced by ac- CL. III.-OR. I.] SANGUINEOUS FUNCTION. 39 cumulated excitability, and marked by direct debility; the latter occasioned by exhausted excitability, and marked by indirect debi- lity. The remedial plan is as simple as the arrangement. Bleed- ing, low diet, and purging, cure the sthenic diseases; and stimulants of various kinds and degrees, the asthenic. Fevers, therefore, under this hypothesis, like other diseases, are either sthenic or asthenic; they result from accumulated or exhaust- ed excitability. Synocha, or inflammatory fever (cauma under the present arrangement), belongs to the first division, and typhus to the second. Let us try the system by these examples. The first symptoms of inflammatory fever, like those of all others, evince, as I have already observed, debility or languid action in every organ,—let the debility be distinguished by whatever epithet it may. The vital flametis weak, and scarcely capable of being supported ; and yet the fuel is more inflammable than in a state of health, the excitability is accumulated. This scheme, therefore, completely fails in accounting for the origin or first stage of inflam- matory, or, in Dr. Brown's own language, sthenic fever. Typhus pestilens, or jail-fever, is arranged by Dr. Brown as an asthenic disease; and, as such, we have reason to expect debility as characteristic of its entire progress. Yet what is it that produces this debility ? The blast or stimulus is here contagion; and the ex- citability is exhausted by the violence of this blast or stimulus; but there is no means of its becoming exhausted without increasing the excitement: the fuel can only be lessened by augmenting the flame that consumes it. Yet in typhus, according to this hypothesis, the fuel is expended, not in proportion as the flame is active and vio- lent, but in proportion as it is weak and efficient. The excitability is exhausted, and the debility increases in proportion as the excite- ment forbears to draw upon it for a supply. The blast blows hard but without raising the fire, and yet the fuel consumes rapidly. This scheme, therefore, completely fails, in accounting for any stage of low or asthenic fevers of every description. Dr. Brown, however, was not a man of much practice ; his wri- tings show that he was but little versed in the symptoms of diseases; his descriptions are meagre and confused : and hence, when he comes to assort diseases into the only two niches he allots for their reception, he makes sad work; and maladies of the most opposite characters, and demanding the most opposite mode of treatment, are huddled together to be treated in the same manner, in many cases with no small risk to the patient. Thus, among the sthenic diseases are associated rheumatism, erysipelas, scarlet and inflammatory fe- ver ; and, among the asthenic, gout, typhus, apoplexy, and dropsy. The Brunonian hypothesis, nevertheless, offers one principle that is unquestionably founded on fact, and is peculiarly worthy of atten- tion ; I mean, that of accumulated excitability from an absence or defect of stimuli; in colloquial language, an increase of energy by rest. And it is this principle which forms the hinge on which turns the more finished system of Dr. Darwin. Sensible of the objection that weighs equally against that part of 40 HJEMATICA. [CL. III.-OR. 1. the system of Dr. Cullen and Dr. Brown, which represents the energy or excitability of the living frame as capable of recruiting itself after collapse or exhaustion, without a recruiting material to feed on; he directly allows the existence of such a material; regards it as a peculiar secretion, and the brain as the organ that elaborates and pours it forth. The brain, therefore, in the system of Dr. Darwin, is the common fountain from which every Other organ is supplied with sensorial fluid, and is itself supplied from the blood as the blood is from the food of the stomach. All this is intelligible; but when beyond this he endows his sensorial fluid with a mental as well as a corporeal faculty, makes it the vehicle of ideas as well as of sensation, and tells us that ideas are the actual w contractions, or motions, or configurations, of the fibres which constitute the immediate organ of sense,"* he wanders very unnecessarily from his subject, and clogs it with all the errors of materialism. He supposes the sensorial power, thus secreted, to be capable of exhaustion in four different ways, or through four different faculties of which it is possessed: the faculty of irritability, exhausted by external stimuli affecting simple irritable fibres : that of sensibility, exhausted by stimuli affecting the fibres of the organs of sense : that of voluntarity, exhausted by stimuli affecting the fibres of the voluntary organs acting in obedience to the command of the will: and that of associability, exhausted by stimuli affecting organs asso- ciated in their actions by sympathy or long habit. By all or any of these means, the sensorial power becomes evacuated, as by food and rest it becomes replenished, often, indeed, with an accumulation or surplus stock of power. In applying this doctrine to fever, he considers its occasional causes, whatever they may be, as inducing a quiescence or torpor of the extreme arteries, and the subsequent heat as an inordinate exer] tion of the sensorial power hereby accumulated to excess; and, consequently, the fever of Dr. Darwin commences a stage lower than that of Dr. Cullen, or in the cold fit instead of in a collapse of the nervous energy lodged in the brain. Now, allowing this explanation to account for the cold and hot stages of a single paroxysm of fever, like the spasm of Dr. Cullen, it will apply no farther. For when the sensorium has exhausted itself of its accumulated irritability, the disease should cease. It may, perhaps, be said, that a second torpor will be produced by this very exhaustion, and a second paroxysm must necessarily ensue. Admitting this, however, for a moment, it must be obvious that the first or torpid stage only can ensue ; for the system being now quite exhausted, the quiescence that takes place during the torpor can only be supposed to recruit the common supply necessary for health; we have no reason to conceive, nor is any held out to us, that this quantity can again rise to a surplus. Yet it must be farther remark- ed, that in continued fevers we have often no return of torpor or * Zoonom. Vol. I. Sect. n. ii. 7. CL. III.-OR. I.] SANGUINEOUS FUNCTION. 41 quietude whatever, and, consequently, no means of re-accumnlating irritability ; but one continued train of preternatural action and exhaustion, till the system is completely worn out. And to this objection the Darwinian hypothesis seems to be altogether without a reply. It is not necessary to pursue this subject further. Other conjec- tures more or less liscrepant from those now examined have been offered, but they have not acquired sufficient notice, or evinced sufficient ingenuity to be worthy of examination. V. There are other pathologists who have referred the proxi- mate cause of fever to a morbid affection of some particular organ, or set of organs associated in a common function. Thus, Baron Haller alludes to several in his day, who ascribed it to a diseased state of the vena cava :* Bianchi pitched upon the liver,! Swalve on the pancreas,| Rahn on the digestive organization generally,^ and Dr. Clutterbuck has still more lately, in our own country, and with far more reason and learning, brought forward the brain; to an inflammation of which organ he ascribes fevers of every kind, regarding them merely as so many varieties of one specific disease, originating from this one common cause.|| But this is to confound fever with local inflammation, the idiopathic with the symptomatic affection. In treating of inflammation under the ensuing Order, we shall have sufficient opportunities of seeing that an inflamed state of almost any organ, and especially of membranous organs, or the membranous parts of organs, is sufficient to excite some degree of fever or other, and not unfrequently fever of the highest degree of danger from its duration or violence. And hence, the liver, the lungs, the stomach, the intestines, the peritoneum, and the brain, have an equal claim to be regarded as furnishing a proximate cause of fever when in a state of inflammation. A very striking objection to Dr. Clutterbuck's hypothesis, is his limiting himself to a single organ as the cause of an effect which is equally common to all of them. And on this ground it is that Professor Marcus of Bavaria, who has contended with similar strenuousness for the identity of fever and inflammation, has regard- ed all inflamed organs as equal causes; and is hereby enabled to account, which Dr. Clutterbuck's more restricted view does not so well allow of, for the different kinds of fever that are perpetually springing before us, one organ giving rise to one, and another to another. Thus, inflammation of the brain, according to Dr. Marcus, is the proximate cause of typhus; inflammation of the lungs, of * Bibl. Med. Pr. i. p. 112. t Hist. Hepat. p. ll£ X Pancreas,*&c. p. 141.

I1I.-0R. fc hectic fever; that of the peritoneum, of puerperal fever; and that of the mucous membrane of the trachea, of catarrhal fever. The general answer, however, to pathologists of every descrip- tion who thus confound or identify fever with inflammation, whether of a single organ or of all organs equally, is, that though fever is commonly a symptom or sequel of inflammation, inflammation is not uncommonly a symptom or sequel of fevers. And hence,. though post-obit examinations, in the case of those who have died of fever, should show inflammation in the brain, the liver, or any other organ, it is by no means a proof that the disease originated there, since the same appearance may take place equally as an effect, and as a cause. Whilst a single example of fever terminating fatally without a trace of inflammation in any organ whatever, and such examples are perpetually occurring, is sufficient to establish the existence of fever as an idiopathic malady, and to separate the febrile from the phlogotie divisions of diseages. " A fever, therefore," to adopt the language of Dr. Fordyce, " is a disease that affects the whole system ; it affects the head, the trunk of the body, and the extremities ; it affects the circulation, the absorption, and the nervous system ; it affects the skin, the muscular fibres, and the membranes; it affects the body, and affects likewise the mind. It is, therefore, a disease of the whole system in every kind of sense. It does not, however, affect the various parts of the system uniformly and equally; but, on the contrary, sometimes one part is much affected in proportion to th^e affection of another paTt."* The result of the whole, as observed at the outset of this intro- duction, is that we know little or nothing of the proximate cause of fever, or the means by which its phaenomena are immediately produced*. In the language of Lieutaud applied to the subject before us, they are too often atra, caligine mersae ; nor have any of the systems hitherto invented to explain this recondite inquiry, however ingenious or elaborate, answered the purpose for which they were contrived. From the proximate cause of fever let. us next proceed to a few remarks upon its remote causes. Dr. Cullen, who has striven so strongly and so ingeniously to simplify the former, has made a similar attempt in respect to the latter. He first resolves all remote causes into debilitating or sedative powers, instead of being stimulant as they were formerly very generally considered, and as they are still regarded by many pathologists, and especially by those who contemplate fever and inflammation as identic. Whether this position of Dr. Cullen be correct or not, it was necessary for him to lay it down and to maintain it, or he must have abandoned his system of fever alto- gether, which supposes it to commence in, and be "primarily depen- dant upon debility. J' F These sedative or debilitating causes he reduces to two MARSH * On Fever, Dissert, i. p. 28. CL. IH.-OR. I.] SANGUINEOUS FUNCTION. 43 and human effluvia. To the former of which he limits the term miasmata, and the power of producing intermittent fevers, which, with him, include remittent; while to the latter he confines the term contagions, and the power of producing continued fevers. it is true he has found himself compelled to take notice of a few other powers, as cold, fear, intemperance in venery or drinking; but these he is disposed to regard as little or nothing more than sub-agents, or co-agents, scarcely capable of producing fever by themselves. " Whether fear or excess be alone," says he, " the remote cause of fever, or if they only operate either as concurring with the operation of marsh or human effluvia, or on giving an opportunity to the operation of cold, are questions not to be positively answered : they may possibly of themselves produce fever ; but most frequently they operate as concurring in one or other of the ways above mentioned."* To cold, however, he attributes a power of engen- dering fever more freely than to the rest; " yet even this," says he, v is commonly only an exciting cause concurring with the operation of human or marsh effluvia.! We shall find, as we proceed, that these supplemental causes may admit of addition; as we shall also that they more frequently exist as independent agents than Dr. Cullen is disposed to allow. Yet there can be littfc doubt that the chief and most extensive causes of fever are human and marsh effluvia. No great benefit, however, has resulted from endeavouring to draw a line of distinction between these two terms, and hence it is a distinction which has been very little attended to of late years. Miasm is a Greek word, importing pollution, corruption, or defile- ment generally ; and contagion, a Latin word, importing the applica- tion of such miasm or corruption to the body by the medium of touch. There is, hence, therefore, neither parallelism nor antago- nism, in their respective significations: there is nothing that neces- sarily connects them either disjunctively or conjunctively. Both equally apply to the animal and the vegetable worlds—or to any source whatever of defilement and touch ; and either may be predi- cated of the other; for we may speak correctly of the miasm of contagion, or of contagion produced by miasm. And hence it is that the latter term is equally applied by Sauvages to both kinds of effluvia : " Miasmata, turn sponte in sanguine enata, turn extus ex aere, in massam sanguineam delata."J It is a question of more importance whether we have yet the means of realizing the distinction between human and marsh mias- mata, which Dr. Cullen has here laid down, and which has been generally adopted from the weight of his authority. All specific miasmata may be regarded as morbid ferments, capable of suspen- * Pract. of Phys. Book I. Ch. iv. Sect. xcvu. t Id. Sect. xcn. ! Nosol. Method. CI. n. Febr. Theor.

III.-OR. h sion in the atmosphere, but varying very considerably in their degree of volatility, from that of the plague, which rarely quits the person except by immediate contact, to that of the spasmodic^ cho- lera of India, which, as observed when treating of it,* works its way, if it be really from a specific poison, in the teeth of the most powerful monsoons, despising equally all temperatures of the atmos- phere and all salubrities of district, and travelling with the rapidity of the fleetest epidemy. They are of various kinds, and appear to issue frftm various sources, but we can only discriminate them by their specific effects. These are most clearly exemplified in the order of exanthems: in which for some thousands of years they have proved themselves to be of a determined character in all parts of the world where they have been the subject of observation, dif- fering only in circumstances that may be imputed to seasons; climate, and other external causes, or to the peculiar constitutions of the individuals affected. Thus, the miasm of small pox has uniformly continued true to small pox, and that of measles, to measles; and neither of ttiem has, in a single instance, ran into the other disease, or produced any other malady than its own. But can we say the same of the supposed two distinct miasms of marsh and human effluvia? Is it equally true that the former has never produced any other than intermittent fever, or the latter any other than continued 1 And is it also equally truqgliat each of these maladies adheres as strictly to its own character in every age, and every part of the world, as small pox and measles; and that they have uniformly shown as strong an indisposition to run into each other ? Dr. Cullen's system is built upon an affirmative to these questions. For it, in fact, allows but two kinds of fever, each as distinctly proceeding from its own specific miarm as any of the exanthems. But this is to suppose what is contradicted by the occurrences of every day: which compel us to confess that, while we cannot draw a line of distinction between marsh and human effluvia from their specific effects, we have no other mode of distinguishing them. Some writers, indeed, have denied that intermittents, or rather the intermittents of marsh-lands, are produced by a miasm of any kind ; for they deny that any kind of miasm is generated there ; and contend that the only cause of intermittents, in such situa- tions, is air vitiated by being deprived of its proper proportion of oxygene in consequence of vegetable and animal putrefaction, com- bined with the debilitating heat of the autumnal day, and the seda- tive cold and damp of the autumnal night.! But this opinion is too loosely supported to be worthy of much attention. It is sufficient- ly disproved by the intermittent described by Sir George Baker as existing in the more elevated situations of Lincolnshire, while * Class i. Ord. i. Gen. ix. Spec. in. t Currie. Trans. Amer. Phil. Soc. CL. III.-OR. I.] SANGUINEOUS FUNCTION. 45 the adjoining fens were quite free from it.* We have as much reason to suppose a febrile miasm in intermittents as in typhus; and in some instances they have been found' as decidedly-conta- gious. " That intermittent fevers," says Dr. Fordyce, " produce this matter, or, in other words, are infectious, the author (meaning himself) knows from his own observation, as well as from that of others."! And notwithstanding that it becomes us to speak with diffidence upon a subject respecting which we are so much in want of in- formation, I may venture to anticipate that the evidence to be advanced in the ensuing pages upon the general nature and diver- sities of fever, will show that there is more reason for believing that the febrile principle produced by marsh and human effluvia is a common miasm, only varying in its effects by accidental modi- fications, and equally productive of contagion, than that it consists of two distinct poisons, giving rise to two distinct fevers, the one essentially contagious, and the other essentially uncontagious, as contended for by Dr. Cullen. .- »<|; In effect, we shall, 1 think, perceive that this mysterious subject is capable of being, in some degree, more clearly elucidated and still farther simplified than it has been by preceding pathologists. In the decomposition of all organised matter, whether vegetable or animal, when suddenly effected by the aid of heat and moisture, an effluvium is thrown forth that is at all times highly injurious to the health, and, in a closely concentrated state, fatal to life itself. Thus, we are told by Fourcroy, that in some of the burial grounds in France, whose graves are dug up sooner than they ought to be, the effluvium from an abdomen suddenly opened by a stroke of the mattock, strikes so forcibly upon the grave-digger as to throw him into a state of asphyxy, if close at hand; and if at a little dis- tance, to oppress him with vertigo, fainting, nausea, loss of appe- tite, and tremours for many hours : whilst numbers of those who live in the neighbourhood of such cemeteries labour under de- jected spirits, sallow countenances, and febrile emaciation.J This effluvium is from the decomposition of animal matter alone ; but the foul and stinking harmattan, when it rushes from the south-east upon the Guinea coast, loaded with vegetable exhalations alone, with which it impregnates itself while sweeping over the immense uninhabitable swamps and oozy mangrove thickets of the sultry regions of Benin, triumphs in a still more rapid and wasteful de- struction ; insomuch that Dr. Lind informs us, that the mortality produced by this pestilential vapour in the year 1754 or 1755 was so general, that in several negro towns the living were not suffi- cient to bury the dead; and that the gates of Cape Coast Castle * Medic.

IH.-OR. *• were shut up for want of centinels to perform duty; blacks and whites falling promiscuously before this fatal scourge. In this case, as in the preceding, the vapour is always accompa- nied with an intolerable stench from the play of affinities between the different gases that are let loose by the putrefactive decpmpo- sition ; and hence it is impossible to affirm that the mortality thus pro- duced is the result of any single or specific miasm operating to this et- feet. But it shows us that the general effluvium from the decom- position of all dead organized matter, whether animal or vegetable, is equally deleterious to health and life. The decomposition, however, to which we are, on the present occasion, chiefly to direct our attention, is of a mixed kind; for the marsh and oozy soil of inhabited countries is necessarily a combi-, nation of animal and vegetable matter. If this decomposition take place slowly, as in cold or dry wear ther, and more particularly in a breezy atmosphere, not the slight- est evil is sustained during its entire process. And hence, in order to render it mischievous, and particularly in order to render it ca- pable of producing fever of any kind, it is necessary that it should be assisted by the co-operation of certain agents, many of which we do not seem to be acquainted with, but which, so far as we are ca- pable of tracing them, appear to be auxiliary to the general pro- cess of putrefaction, as warmth, moisture, air, and rest or stagnation. The simplest and slightest fever that is produced under the joint influence of these powers, is the intermittent: and we find these produced where their joint influence is but feeble, and where it exists, perhaps, in its lowest stage, as in the favourable climate of our own country; where we are not often overloaded with equi- noxial rains, and have not often to complain of a sultry sky or a stagnant atmosphere. Even here, however, we perceive a change in the character of the intermittent at different seasons: for while in the spring it usually exhibits a tertian type, in the autumn we find it assume a quartan. And as these can only be contemplated as varying branches of the same disease, we have thus far, at least, reason to regard it as produced by a common febrile miasm, modi- fied in its operation by a variation in the relative proportion which its auxiliaries, known and unknown, bear to each other during the vernal and autumnal seasons; coupled, perhaps, with some degree of change produced by the same seasons in the state of the human body. If from our own country we throw our eyes over the globe, we shall find in every part of it, where the same causes exist, that in proportion as they rise in potency they produce a fever of a severer kind, more violent in its symptoms, and more curtailed in its intervals, till we gradually meet, first with no distinct intervals, and at length with no intervals whatever; and hence perceive the remittent progressively converted into intermittent and continued fevers. And that here we have still the same miasm merely mo- dified in its operation by the varied action of its auxiliary powers CL. III.-OR. I.] SANGUINEOUS FUNCTION. 47 on the constitution of the individuals it attacks, is as clear as in the former case : because, in many attacks, we see different individuals touched by the very same influence, exhibit all the varieties now alluded to, and intermittent, remittent, and continued fevers co-ex- isting in every • diversity of violence ; commencing with eithei*bf these forms ; keeping true to the form with which they commenc- ed ; or changing one form for another. Such more particularly was .the fact in the highly malignant yellow-fever of Antigua in 1816, as fully and admirably described by Dr. Musgrave,* and to which we shall have occasion to refer more particularly in its proper place. , This disease first showed itself during sultry weather and a quiet atmosphere, in a swampy part of the island, among a ship's crew lately arrived, but from a healthy vessel, and themselves in good health at first landing. It soon spread widely, and at length indis- criminately in town and country, among ail ranks and conditions, and situations, blacks as well as whites, the oldest settlers as well as the newest comers. The head was, in some cases, chiefly af- fected ; in others the stomach, the liver, or a still different organ. Hiccough and black vomit were common towards the close of the disease, though many died without it; and recovery was no exemp- tion from a second attack. Dr. Musgrave asserts farther, that, during the whole of this fatal epidemy, there was no instance of its being received by contagion. The argument however, which he offers upon this subject is not quite convincing. Yet admitting the fact to be as he states it, we have an additional proof, if proof were wanting, firstly, that when the animal frame has been previously debilitated or relaxed, as in the case of a ship's crew that has been long voyaging in high lati- tudes and living on salted provisions, it suffers sooner and more severely than where no such relaxation has taken place: and, secondly, that by a long and gradual exposure to the influence of febrile miasm, however produced, whether from the living human body or from dead organized matter, the animal frame becomes torpid to its action, as it does to the action of other irritants. Whence prisoners confined in jails with typhous miasm around them, as well as those who have long stood the climate in the West Indies, receive the contamination to which they are exposed far less rapidly than strangers. The argument, however, of Dr. Musgrave upon this point, we have- said, is not quite satisfactory; because he admits that those who were about the patients, and paid no attention to personal cleanliness, did not wholly escape ; out then, says he, they escaped as generally and were not more frequently affected than those who never entered the doors of an infirmary. Now as all ranks and conditions, blacks and whites, even far off in the country, were af- fected indiscriminately, we have no reason to expect that those * Medico-Chirurg. Trans. Vol. ix. p. 92. 48 HiEMATICA. tCL* nI'-°R- T whose habits had rendered them peculiarly torpid to the action of the febrile miasm should be more frequently affected than others. The very admission that they were as much so, seems to imply that the febrile miasm was attacking them in some new mode, against which they were not guarded by previous habit. Nor is it easy to conceive by what means the local disorder of the coast could be converted into so extensive an epidemy unless through the medium of contagion. . I have dwelt the longer upon this subject, because it is desirable to reconcile as much as possible the conflicting testimony of respec- table writers, who, having adopted different theories, are insensi- bly led to support them by inaccordant descriptions of the same dis- ease. In direct opposition to Dr. Musgrave, Dr. Bancroft,* and a host of distinguished writers who think with them, we are told by Mr. Pym, that the Bulam fever, admitted by Dr. Musgrave to be the same as the above, not only is contagious, but is never introduced into any fresh region but by contagion.! While Dr. Rush, speak- ing of the yellow fever of Philadelphia of 1793, asserts, that " there were for several weeks two sources of infection, viz. exhalation and contagion. The exhalation," says he, " infected at the distance of three and four hundred yards, while the contagion infected only across the streets. After the 12th of September, the atmosphere of every street in the city was loaded with contagion." He adds, that a few caught the disease who had it before: thus taking a middle course between Dr. Musgrave, who tells us that recovery affords "'no exemption from a second attack," and Mr. Pym, who affirms that the fever " attacks the human constitution but once." In the fever of Cadiz of the year 1800, Sir James Fellowes, who coincides in the view adopted by Mr. Pym, asserts, not only that it was contagious and propagated only by contagion, but that " the air from its stagnant state became so vitiated that its noxious quali- ties affected even animals : canary birds died with blood issuing from their bills, and in all the neighbouring towns, which were afterwards infested, no sparrow ever appeared."! 1 do not remember to have seen this last fact so directly affirm- ed by any modern writer; but it is not contradicted in the course of the controversy, and is in perfect coincidence with the state of the air during the plague in most places,§ and particularly at Athens, as described by Thucydides: rtufctifiov h rm f*ti totovrui •pitim f?iAfCL. III.-OR. I.] SANGUINEOUS FUNCTION. 53 3. The nature of the fever depends, partly upon the state of the body at the time of attack; but chiefly upon some modification in the powers or qualities of the febrile miasm, by the varying pro- portions of these agents in relation to each other, in different places and seasons. Arid hence^the diversities of quotidians, tertians, and quartans; remittent and continued fevers, sometimes mild and some- times malignant. 4. The decomposition of the effluvium transmitted from the liv- ing human body, producer a miasm similar to that generated by a decomposition of dead organized matter, and hence, capable of be- coming a cause of fever under the influence of like agents. 5'. The fever thus excited, is varied or.modified by many of the same incidents that modify the miasmic principle when issuing from dead Organized matter; and hence, a' like diversity of type and vehemence. 6. During the action of the fever thus produced, the effluvium from the living body is loaded with miasm of the same kind, com- pletely elaborated as it passes off, and standing in no need of a de- composition of the effluvium for its formation. Under this form it is commonly known by the name of febrile contagion. In many cases, all the secretions are alike contaminated; and hence, febrile miasm of this kind is often absorbed, in dissection, by an accidental wound in the hand, and excites its specific influence on the body of the anatomist. 7. The miasm of human effluvium is chiefly distinguishable from that of dead organized matter, by being less volatile, and having a power of more directly exhausting or debilitating the sensorial energy, When once received into the system. Whence the fevers generated in jails or other confined and crowded scenes, contami- nate the atmosphere to a less distance than those from marshes and other swamps, but act with a greater degree of depression on the living fibre. 8. The more stagnant the atmosphere, the more accumulated the miasmic corpuscles from whatever source derived; and the more accumulated these corpuscles, the more general the disease. 9. The miasmic material becomes dissolved or decomposed in a free influx of atmospheric air; and the purer the air the more readily the dissolution takes place : whence, e contrario, the fouler as well as more stagnant the air, the more readily it spreads its in- fection. 10. Under particular circumstances, and where the atmosphere is peculiarly loaded with contamination, the miasm that affects man, is capable also of affecting other animals. 11. By a long and gradual exposure to the influence of febrile miasm, however produced, the human frame becomes torpid to its action, as it does to the action of other irritants ; whence the na- tives of swampy countries, and prisoners confined in jails with typh- ous contamination around them, are affected far less readily than strangers; and, in numerous instances, are not affected at all. 54 HAEMATIC A. [CL, III.-OR. I. 12. For the same reason, those who have once suffered from fever of whatever kind hereby produced, are less liable to be in- fluenced a second time ; and, in some instances, seem to obtain a complete emancipation. It only remains to offer a few remarks upon the doctrine of crises ; or that tendency which fevers are by many supposed to pos- sess, of undergoing a sudden change at particular periods of their progress. A sudden and considerable variation of any kind, whether favoura- ble or unfavourable, occurring in the course of the general disease. and producing an influence on its character, is still loosely expres- sed by the name of crisis. The term is Greek, and pathologically imports a separation, secretion, or excretion of something from the body; which was in truth the meaning ascribed to it when first em- ployed, agreeably to the hypothesis of concoction which we have just considered. The original hypothesis is abandoned; but the term is still continued in the sense now offered. That changes of this kind are perpetually occurring in the pro- gress of continued fevers, must, 1 think, be admitted by every con- siderate and experienced practitioner. Nothing is more common than to behold a patient suddenly and unexpectedly grow decidedly better or worse in the progress of a fever of almost any kind, and pass on rapidly towards a successful or an unsuccessful termination. But the important question is, whether there be any particular periods in the progress of a fever in which such changes may be expected '! Hippocrates conceived there were; he endeavoured to point out and distinguish them by the name of critical days. As- clepiades and Celsus denied the existence of such periods; and the same diversity of opinion has prevailed in modern times. It is not very easy to determine upon the subject in the present day, and especially in our own country. For, first, fever, like many other complaints, may have undergone some change in its progress from a like change in the nature of its remote causes, or in the constitution of man. And, next, it seems to be generally allowed, that sudden transitions, whether regular or irregular, are more apt to take place in almost all diseases in warm than in cold climates. On these grounds, it is probably a subject which will never become of great practical importance at home. Yet it is well worthy of attention as a question of history, and which may yet be of great importance to many parts of the world. If we examine the phenomena of the animal economy, as they occur in ^natural series, we shall find that they are in almost every instance governed by a periodical revolution. A man, in a state of health and regular habits, generally becomes exhausted of sensorial power within a given period of time, and requires a periodical suc- cession of rest: his appetite requires a periodical supply, and his intestines a periodical evacuation. This tendency equally accom- panies and even haunts him in disease ; he cannot disengage himself from it. Gout, rheumatism, mania, rapidly and pertinaciously estab- CL. III.-OR. I.] SANGUINEOUS FUNCTION. 55 lish to themselves periods of return. The hemorrhoidal discharge often does this; and the catamenia constantly. The same occurs in fevers, but especially in intermittents; for the quotidian, the ter- tian, the quartan, have, upon the whole, very exact revolutions. And, though accidental circumstances may occasionally produce a considerable influence on every one of these facts, whether morbid or natural, the tendency to a revolutionary course is clear and un- questionable. Now, although Hippocrates has not appealed to this reasoning, it forms a foundation for his observations : and when stript of the perplexities that encumber h's writings upon this subject, partly produced by erroneous transcripts, and in a few instances perhaps by his own irresistible attachment to the Pythagorean hypothesis of numbers, he vmy be regarded as laying down the following as the critical days of continued fever: the 3d, 5th, 7th, 9th, 11th, 14th, 17th, 20th; beyond which it is not worth while to follow the series, for it is not cften that they extend further. In other parts of bis works, he regards also the 4th and 6th fttid even the 21st «-.s critical days; so that in the first week, every day, after the disease has fully established itself, evinces a disposition to a serious change ; in the second week, every other day ; and in the third week, every third day. It is not easy to determine why the 21st day should be a critical day as well as the 20th. Various con- jectures have been offered upon the subject; by some, it has been regarded as a mistake in the Greek copy, and by others, as a piece of favouritism in Hippocrates for this number, in consequence of its being an imperfect one in the Pythagorean philosophy, as the commencement of a septenary. De Haen with rigid and patient assiduity has put Hippocrates to the test upon these data; for he has accurately analyzed Hippocra- tes's own journal of the numerous cases of fever he has most in- dustriously collected and recorded, and finds the positions, in most instances, to be strictly justified ; and that out of 168 terminations of fever, not less than 107, or more than two-thirds, happened on the days denominated critical, not reckoning the 4th, 6th, or 21st, and that the 4th and 6th were very frequently critical. There are a few anomalies; but it is not necessary to notice them, because they are easily referable to accidental causes, similar to those that retard or accelerate the paroxysm of intermitting fevers. Now, admitting the Hippocratic table to be true, the continued fever, in its progress, is measured by the various types exhibited by intermittent fevers. Thus, the quotidian prevails through the first seven days ; there is on each day a slight exacerbation, and no one day is more critical than any other. Alter this period the ter- tian type commences, and runs through the ensuing week; the principal changes occur on the 9th and 11th days, and would occur on the 13th, but that the quartan type now assumes its prerogative ; and the principal transitions after the 11th. take place on the 14th, instead of on the 13th; on the 17th; and on the 20th. Dr. 56 ILEMATICA. [«- I«.-©»' «' Cullen who has examined this subject with great attention, and simplified it from many of its difficulties, directly asserts that his own experience coincides with the critical days of Hippocrates , and Dr. Fordyce, who scarcely does justice to Cullen upon other points, unites with him upon the present, and justly compliments him upon his ingenious examination and explanation of the Greek distribution of critical days. It is, nevertheless, admitted on all hands, that the order of succession is far less distinct as well as less regular in cold than in warm climates; and that it requires a thoroughly attentive and practised eye to notice these changes in our own country, or indeed in any part of northern Europe. And hence, Craanen says, it is lost time to look for them ;* Stoll, that they are only to be found in inflammatory fevers ;t and Le Roy, that the supposed critical days have no influence and can lead to no prognosis or peculiarity of practice. J Why the first week of a fe- ver should incline to a quotidian type rather than to a tertain, or the second to a tertian rather than to a quartan, we know no more than we do why fevers should ever intermit, or at any time observe the distinctions of different types. We are in total ignorance upon all these subjects. We see, moreover, that intermitting fevers, whether quotidian, tertian, or quartan, have their paroxysms recur regularly in the day time ; the quotidian in the morning, the tertian at noon, and the quartan in the afternoon; and that in no instance do the paroxysms take place at night: and we see also that in con- tinued fevers, the exacerbations uniformly take place later in the day, than the paroxysms of the latest intermittent; for these rarely occur earlier than between five and six o'clock in the evening, while the paroxysms of the quartan return commonly before five. Of these interesting and curious scenes we are spectators ; but we are nothing more; for we are not admitted to the machinery be- hind the curtains. By some pathologists the source of these phenomena is sought in the influences of the heavenly bodies, and especially in those of the sun and the moon. In ancienttimes these luminaries were supposed to produce an effect on all diseases, and especially on mania, epilepsy, catameuia,*and pregnancy. And when the Newtonian philosophy first illumined mankind with the brilliant doctrine of universal at- traction, Dr. Mead stepped forth into the arena, and revived and supported the ancient doctrine with great learning and ingenuity. And as an ingenious conjecture and possible fact, of which no prac- tical use could be made, it was contemplated till towards the close of the last century: about which time Dr Darwin, by interweaving it with his new hypothesis, once more endeavoured to raise it into popular notice, and give it an air of serious importance. Dr. Bal- four, of British India, however, has still more lately brought it for- * De Hoinine. t Rat. Med. Part iv. p. 283. X Du Prognostic dans lee Maladies Aigues, 8vo. Morrtpel. 1778. CL. III.-OR. I.] SANGUINEOUS FUNCTION. 57 ward as a doctrine capable of direct proof, and as peculiarly affect- ing the progress of fevers. His opinion, which he endeavours to support by weighty facts and arguments, is, that the influence of the sun and the moon, when in a state of conjunction, which is named sol-lunar influence, produces paroxysms or exacerbations in conti- nued fever in all cases in which a paroxysmal diathesis (for such is his expression") exists ; and as this influence declines, in consequence of the gradual separation of these luminaries from each other, and their getting into a state of opposition, a way is left open to the system for a critical and beneficial change, which is so sure to take place provided the critical disposition is at this time matured. In other words, paroxysms and exacerbations in fever may be expect- ed to take place (and do in fact take place) at spring-tides, and cri- ses at neap-tides. This is a new view of the influence of the heavenly bodies upon the human frame; and a view which, though feebly supported by facts, is advanced with all the dogmatism of an established science. There is, nevertheless, more in medical astrology than is, perhaps, generally supposed; it is an important branch of meteorology, and, as such, is well worth studying. Nor can there, I think, be a question in any impartial mind, that, under certain circumstances, and especially in tropical climates, many diseases are influenced by lu- nation, as we are sure they are, in all climates, by insolation. The concurrent observations of a host of candid and attentive pathologists, who have been witnesses of what they relate, are sufficient to im- press us with this belief: but till we know more fully what these circumstances are, we cannot avail ourselves of their remarks, and can only treasure them up as so many isolated facts. And hence it is, that in no age or country whatever, has the study been turned to any practical advantage, expedited the cure of a disease, or ena- bled us to transform the type or interval of one kind of fever into that of another. Nor is it any exclusive reproach to the art of me- dicine that it should be so ; for of all the subdivisions of general phi- losophy, there is none so little entitled to the name of a science as meteorology itself. And till the naturalist has explained the varia- tions of the barometer, the physician need not blush at being inca- pable of turning to account the supposed influence of the planets, or of unfolding the origin or tracing the capricious courses of epi- demics and pestilences. voi. n. ■'>*» H/EMATICA.

This is the simplest form in which fever at any time makes its at- tack ; and hence Dr. Fordyce has distinguished it by the name of simple fever. For the purpose, however, of entering into the full character, not only of the present but of all the subsequent genera, and their respective species, it is necessary to bear in mind, that the ordinal definition forms a part of that character, and is essential- ly included in a less or greater degree in all the subdivisions that appertain to it. I have said that the ephemera rarely exceeds a duration of twen- ty-four hours. Sorne practitioners, however, have called by this name a fever that has extended for three days; and Sauvages has arranged this mode of fever under his own genus of ephemera. But this is to confound different species under one generic name. Fordyce asserts, that he has often seen the ephemera commence its attack with all the essential appearances of fever, and terminate in eight, ten, or twelve hours.* And hence, in defining ephemera, the symptom of duration ought not to exceed the limit here allotted to it. In this simple shape of the disease, the pathognomic symptoms are few and striking; for, however violent, it is confined to a single paroxysm of three distinct stages, shivering or languor, heat, and perspiration, each most probably dependent on the other, and ceasing, when true to itself, after having followed up the movements of the animal frame through a single diurnal revolution. The cold stage, however, is often scarcely perceptible, and sometimes altogether imperceptible, the general languor taking place without it. The genus exhibits two common and very distinct species ; and if the ephemera sudatoria of Sauvages, the sweating-sickness or English plague of other authors, be regarded as belonging to it, as unquestionably it ought, it will then afford us another after the manner following: 1.

WITHOUT PRECEDING RIGOR J LASSITUDE AND DEBILITY INCONSIDERABLE , PAINS OBTUSE, CHIEFLY ABOUT THE HEAD ; HEAT AND NUMBER OF THE TULSE INCREASED SLIGHTLY : PERSPIRATION BREATHING AND PLEASANT. The common exciting causes are, excess of corporeal and especially of muscular exertion ; long protracted study; violent passion; suppressed perspiration ; sudden heat or cold. There are few persons who have not felt this species of diary fever at times, from one or other of the causes just enumerated. When a man has worked himself up into a violent and long conti- nued fit of wrath, whether there have been reason or no reason, and more especially in the latter case ; when he has taken a long and fatiguing journey on foot, walking with great speed, and suffer- ing beneath great heat and perspiration; or when he has devoted the whole of the day to a particular study, so profound and abstract- ing as to exhaust almost the entire stock, of sensorial power that can be drawn from other parts of the system,:at the single ojutlet' of the attention;—and when, beyond this, he still urges his abstruse and protracted train of thought into a late hour of the night or the morning—there is a general irritation or undue excitement pro* duced, that simple rest cannot at once allay; his sleep is short, hurried, and interrupted if he sleep at all; he yawns, stretches his limbs, turns himself again and again in his bed for an easy, perhaps. for a cool place, for his skin is hot and dry; but for a long time he turns in vain. The morning strikes upon his eyes, but he has had little sleep and no refreshment: he is indisposed to leave his bed ; and if he rise, he is still feverish, and unfit for business. He passes the day in disquiet, which perhaps increases towards evening; but at night he feels a moisture breaking forth over his skin, and com- fortably succeeding to the heat and dryness that have thus far dis- tressed him; he recovers perhaps even while sitting up ; but if, as he ought to do, he goes to an early bed, a quiet and refreshing sleep supervenes, and he wakes to the health he before possessed. It is not easy to explain why the febrile paroxysm should be more disposed to close its career sometimes towards the evening, but more generally later at night, except for the reason, whatever that reason may be, that all fevers are far more apt to commence their paroxysms in some part or other of the day-time, and espe- cially intermittents, and consequently to drop them as the day declines. Thus the quotidian makes its assault in the morning, the tertian at noon, and the quartan in the afternoon: as though the GE. I.-SP. I.] 60 HJEMATICA. [CL. ML-OR. I. diurnal revolution were somewhat regularly divided between febrile attack and febrile cessation or truce. It is possible indeed, that a fever of any kind may open its onset at any hour, but this is so contrary to the ordinary rule, that Dr. Fordyce affirms from his own observation that ten fevers commence in the day to one at night. The species before us forms scarcely a case for medicine: since nature or that instinctive power which is ever operating to the general welfare of the animal frame, will be usually found competent to its object. So that if any thing remedially is attempt- edr it should be confined perhaps to a slight increase of the peris- taltic action of the intestines by a dose of neutral salts, and to a removal of the dry heat of the skin by diluents and small doses of ipecacuan, which combines admirably with most aperients, and increases their power, while its own diaphoretic quality continues at least undiminished and is often improved. This is now well known, though not a discovery of recent date; for Gianella, Valer, and various writers of credit, strongly recommended the same from personal experience nearly a century ago.* Gamesters, after sitting up all night, and being worked up to madness by the chances and reverses of their ruinous stakes, are peculiarly subject to this species. A very cold and wet towel tied round the temples seems to give some check to the violent excite- ment of the brain, and diminishes the morbid excess of sensorial power it is in the act of secreting; but in the long run I have gene- rally found persons who have adopted this practice become debili- tated and dropsical, and sink into an untimely grave, or creep on miserably through the fag end of a lingering life, that affords no retrospective comfort, with a hospital of diseases about them. But whether this proceed from the practice adverted to, or from the habitual exhaustion which necessarily accompanies a course of gambling, may admit of a doubt. Vet, the habit itself appears mischievous, however pleasant at the time, as having a strong tendency by frequent repetition' to torpify the secretories of the brain by the rapid and violent change of action they are thus made to undergo. * Gianella, De admirabili Ipecacoanhae virtute in curandis febribus, &c.

SEVERE RIGOR ; GREAT HEAT ; PULSE AT FIRST SMALL AND CONTRACTED, AFTERWARDS FULL AND STRONG; PERSPIRATION COPIOUS ; GREAT LANGUOR. In a few instances the accession is slightly marked, and there is little chilliness or rigor. The heat that succeeds, however, is always considerable ; the face is red and bloated; and there are often pun- gent and throbbing pains in the head, corresponding with the pulsa- tions of the arteries ; though at times tfee pain in the head is dull and heavy. The high-coloured urine deposits a sediment with a tinge of orange-peel We cannot always trace the remote causes of this species; but it is usually produced by some morbid affection of the stomach or of the collatitious viscera. The most obvious and, common cause is that of a surfeit, whether of eating or drinking. And there is no great difficulty in inter- preting the means by which this cause operates. The stomach, in the language of Mr. John Hunter, and it is language confirmed by the experience of every day, is the great seat of general sympathy, and associates with almost every other organ in its action. The digestion of even an ordinary meal is a work of some labour to it, and especially in .weakly constitutions; a greater degree of heat, as I took occasion to show, in the proem to our second class, is regularly expended upon it during this process, and unquestionably also a greater degree of sensorial power; both which, though taken directly from the brain, are taken indirectly from the system at large as from a common stock; and the consequence is that, in infirm habits, a considerable degree of chill and debility are felt during this process, and other organs become torpid while the stomach is in a state of increased action. Hence infants and old persons sleep during digestion; delicate females feel a coldness shooting over their extremities; and those of irritable fibres become flushed in the face, and show other signs of irregular action. Now if this be the case in the digestion of ordinary meals, what disturbance may we not expect during the digestion of a meal that overloads the stomach, and with which the stomach is incapable of grappling ? what, more especially, when at the same time, by an immoderate use of wine or spirits, the brain becomes exhausted of its energy by the excess of stimulus applied to it ? The general chill over the surface, which, in the digestion of an ordinary meal, is only felt by the weak and delicate, is here often felt severely, and sometimes amounts to a horripilation. The 62 ILEMATICA. [CL. III.-OR. L first stage of fever is hence produced : and as the heat and perspira- tion are most probably a necessary result of the first, a foundation is hereby laid for the entire paroxysm. With the reaction that ensues a greater degree of sensorial power is again secreted ; the general frame as well as the brain is roused to an increased energy ; the diaphragm and its associate muscles, instinctively or remedially, contract, and the stomach disgorges its contents, or thrusts them forward half-digested into the duodenum. The only and well known mode of cure consists, in the first place, in imitating this process: in unloading the stomach of its mischievous freight by a powerful emetic, and the alvine canal of whatever portion of the heating and crapulous mass has passed into it by a brisk cathartic. The fever hereby excited will often sub- side in a diurnal revolution; and no tendency to a return of the paroxysm be produced. If the species before us,^iowever generated, do not subside within this period of time, or a few hours beyond it, the disease becomes a cauma, or inflammatory fever of the continued kind, and consequent- ly belongs to the genus enecia. There are, however, a few exceptions to this rule : for Forestus gives a case in which the paroxysm led to a fatal hectic :* and Borelli gives another of equal singularity, in which it kept true to a triennial revolution, returning punctually once every three years.t SPECIES III.

I have followed M. de Sauvages in introducing sweating-fever, the ephemera maligna of Borsieri,| or Burserius as he is more common- ly called, and the sudor Anglieus of most foreign writers, into the present place. Dr. Caius, who practised at* the time of its appearance at Shrews- bury, and has written one of the best accounts of it extant, calls it " a contagious pestilential fever of one day." « It prevailed," says he, « with a mighty slaughter, and the description of it is as tremen- * Lib. 1.

And we are told by Dr. Wil- lis, " that its malignity was so extreme, that as soon as it entered a city it made a daily attack on five or six hundred persons, of whom scarcely one in a hundred recovered." It was certainly a malignant fever of a most debilitating character, but without any tendency to buboes or carbuncles, as in the plague. It ran its course in a single paroxysm; the cold fit and hot fit were equally fatal; but if the patient reached the sweating fit, he commonly escaped. Hence the cure consisted in exciting the sweating stage as quick- ly as possible, and in supporting the system with cordials throughout the whole of the short but vehement course of the fever. At Shrewsbury, it continued to rage for seven months, and during that period of time a thousand fell victims to its violence. But after the discovery of the benefit of the sweating-plan, it was certainly far less fatal. It made its first appearance in London in 1480 or 1483; Caius says in the latter year, first showing itself in the army of Henry VII. on his landing at Milford-Haven. In London, to which however it does not seem to have travelled till a year or two afterward, it took up its abode with various intermissions of activity for nearly forty years. It then visited the continent, overran Holland, Germany, Belgium, Flanders, France, Denmark, and Norway; among which countries it continued its ravages from 1525 to 1530 : it then return- ed to England, and was observed for the last time in 1551. It commenced its attack with a pain in the muscles of the neck, shoulders, legs, or arms, through which a warm aura seemed to creep in many instances; and after these symptoms, broke forth a profuse sweat. The internal organs grew gradually hot, and at length burning, the pungent h£at extending to the extremities, an intolerable thirst, sickness, and jactitation followed speedily, occa- sionally with diarrhoea, and always with extreme prostration of strength, head-ache, delirium, or coma, and a wonderful wasting of the whole body. The sweat was tenacious, saburral, and of an offensive smell; the urine thick and pale; the pulse quick, often irregular; and the breathing laborious from the first. The modes of treatment were often puerile, and offer nothing instructive. A good constitution and exposure to free air seem to have been most successful in promoting a cure. Dr. Caius asserts, that a thick noisome fog preceded the distem- per, especially in Shropshire, and that a black cloud uniformly took the lead, and moved from place to place ; the pestilence in a regu- lar march following its direction. There may be some fancy in this : but it is an unquestionable fact, that the most fatal pestilences of ancient and modern times have been ushered in by stinking fogs or mists, or some other intemperament of the atmosphere, of which the reader will find various instances in the sequel of this work. The disease is generally, however, supposed to have been pro- duced by inclement harvests and vitiated gmin, pcUlicularly wheat, which is less hardy than other grains and soouer infested with albi- 64 HJEMATICA. [CL. III.—OR* '• go (mildew), ustilago (smut), and clavus (ergot or spur). And in proof that this last was the actual cause, it is observed by Dr. Willan, that the contemporary inhabitants of Scotland and Wales, who fed on oaten or barley, instead of on wheaten bread, were not affected. Nevertheless, whatever was the primary cause, a peculiar miasm or contagion seems to have been generated by the disease itself, which chiefly contributed to its spread and continuance. For we are told concurrently by all the writers, that Englishmen who withdrew from their own country into France and Flanders with the hope of escaping the attack of the disease, fared no better than their coun- trymen at home. To which Dr. Freind adds, that, while English- men abroad were thus subject to the contagion, foreigners and even the Scotch in England were rarely or never seized with it ;* a fea- ture that has been copied by Dr. Armstrong in his very forcible description of the complaint, which is perhaps better adapted for poetry than for sober prose. Some, sad at home, and, in the desert, some Abjur'd the fatal commerce of mankind ; In vain: where'er they fled, the fates pursued. Others, with hopes more specious, crossed the main, To seek protection in far distant skies, But none they found. It seemed the general air, From pole to pole, from Atlas to the East, Was then at enmity with English blood: For, but the race of England, all were safe In foreign climes; nor did this fury taste The foreign blood which England then contained.! Something may, perhaps, be set down to the score of a national diathesis ; but without examining vexy closely into the accuracy of this wonderful part of its history, we may at least indulge a hope that this peculiar, most virulent and fatal contagion has long since worn itself out, and become decomposed; though it may be still only latent, and waiting for its proper auxiliaries once more to show itself in the field.]: It is said, indeed, by Dr Coste, the learned editor of Dr. Mead's works in French, that the disease continued to manifest itself occa- sionally as an epidemic in Picardy ; but that, instead of terminating in a single day, it runs on to the third, fifth, and sometimes even to the seventh. It is hence sufficiently obvious that the two fevers though possessing many points of resemblance, are not precisely the same. Yet M. Bellot, in his thesis " An febris putrida Picardii sueti dicta, sudorifera ?" has maintained Dr. Coste's opinion. * Hist, of Physic. Vol. n. p. 533. t Art of Preserving Health, B. m.

PAROXYSM INTERMITTING, AND RETURNING DURING THE COURSE OF THE DIS- EASE : THE INTERMISSIONS GENERALLY PERFECT AND REGULAR. Under the preceding genus, the remote cause, whatever it consists in, lays a foundation for not more than one paroxysm. In the genus before us, the cause introduces a tendency to a recurrence of the paroxysm from the first; and, in most cases, with an interval that continues true to itself as long as the disease lasts. I say in most cases, because we shall see presently, that, when intermittent fever has raged very extensively, it has not unfrequently established a type of one kind in one person, and of another kind in another,; whilst in the same patient quotidians have changed to tertians, ter- tians to quartans, quartans to quotidians, and all of them in a few in- stances to continued fever, in the most capricious and anomalous manner. Dr. Cullen unites intermittents and remittents into one section of fevers, merely distinguishing them as intermittents with an interpos- ed apyrexy, and intermittents with remission alone : and, as already observed, he makes it a part of the pathognomic character of both that they are derived from marsh-miasm—miasmate paludum ortcz— as though there were no other cause of their production, whence Dr. Young gives to intermittents and remittents the common name of paludal fever. The only ground then assumed form this union of intermittents, and remittents, is the supposition that the cause which generates them is single, common to the two, and never generates any other fever. Now, although the febrile miasm issuing from marsh-lands is by far the most common cause of intermittents, it is by no means the only cause ; for we find intermittents, like all other species of fever, produced from various sources; existing in hot countries as well as in cold, in high lands as well as in low lands, sporadically as well as epide- mically ; sometimes excited by sympathy, sometimes by contagion. Even in tertians Dr. Cullen is obliged to admit of instances in which other agents are necessary ; but, then says he, they are only co-agents, and would not operate alone. " Has potestates excitantes pro parte principii hie admittimus, licet ncutiquam excitussent, si miasma palu- dum non antea applicatum fuisset." But this is the very point of controversy ; for in many instances they produce the disease where marsh-miasm cannot be suspected. 1 have seen an isolated case of a regular tertian on the highest part of Islington ; and another on the dry and gravelly coast of Gosport, a situation so healthy that all the VOL. 11. ^ 9 m H.EMATICA. [cl. m.r-0R. r. inhabitants escaped, when in the year 1765 a most fatal and epidem- ic fever, originating unquestionably from the miasm of swampy grounds, pervaded the whole island" of Portsea, situate at not more than a mile distant on the other side of the water, and exhibiting, in different individuals, and often in the same person, all the diver- sities of the intermittent, remittent, and continued type. Dr. For- . dyce affims, that he has seen an intermittent communicated by in- fection, meaning the miasm from human effluvium; and where the yellow fever has long existed or become widely diffusive, this is com- mon. Where it arises from sympathy or organic affection, the case is still clearer. " Two children," says Mr. J. Hunter, " had an ague from worms, which was not in the least relieved by the bark; but by destroying the worms, they were cured." We have in '.like manner agues from many diseases of particular parts, more especial- ly of the liver and the spleen, and from an induration of the mesen- teric glands."* De Meza gives an instance of an intermittent pro- duced by a repelled herpes ;t and Baldertius, by suppressed lochia.J But one of the most singular and convincing proofs, that the de- composition of marsh-lands is not essential to the production of inter- mittent fever, is to be found in the epidemic intermittent of 1780, as described by Sir George Baker, and which we shall have occasion to advert to more particularly hereafter; for, during this, the inter- mittent harassed very extensively the elevated parts of Lincolnshire, while the inhabitants of the neighbouring fens were free from its ravages.§ And in like manner, the dry and healthy climate of Min- orca, is sometimes attacked with remittent of intermittent fever, while Sardinia, proverbial for its insalubrity and febrile epidemics, escapes.|| To unite remittents, therefore, with intermittents, from an idea of their having a single and common origin, is to depart from the clear line of symptoms into a doubtful region of etiology. If inter- mittent ought to be separated (as unquestionably they ought) from continued fevers, so ought remittent to be separated from intermittent, To say that intermittents often run into remittents, is to say nothing, for remittents as often run into continued fever; and it is now an established doctrine that there is no continued fever whatever without occasional remissions. In effect, all fevers have a tendency to run into each other, and many causes are perhaps common to the whole. The difficulty is in drawing the line : yet a like difficulty is perpetually occurring to the physiologist in every part of nature; and equally calls for discrimination in zoology, botany, and mineralogy : and Dr. Parr has correctly observed, that «if a specific distinction can * On Blood, Part n. ch. iv. p. 411. t Act.

II.] SANGUINEOUS FUNCTION. 67 fee established in any branch of natural history, it must be in the separation of remittents from intermittents." Vogel unites remit- tent with continued fevers, to which Cullen, rightly enough, ob- jects ; but the former has as much reason on his side, as the latter has for uniting them with intermittent. Sauvages, Linneus, Sagar, and most modern writers, correctly distinguish each from the other. When an intermitting fever or ague is by the operation of marsh- miasm, or any other cause, once introduced into the system, and has once discovered its type, or given an interval of a particular measure between the close of the first and the commencement of the second paroxysm, it continues true, as a general rule, not mere- ly to the same measure or extent of interval, but to the length and severity of paroxysm, through the whole course of the disease; the character of the cold stage, determining that of the hot, and both together that of the sweating stage ; and the paroxysm ceasing be- cause it has completed its career. But the first interval, like the first paroxysm, which regulates the rest, is of different duration in different cases: of the reason of this difference we know nothing; sometimes it seems to depend upon the season or the temperament of the atmosphere, operating upon the febrile miasm that is diffused through it, and all who have agues in the same place or at the same time, have them of the same kind. Sometimes, on the con- trary, it seems chiefly to depend upon the time of life, the idiosyn- crasy, or the particular condition of the constitution, for, as already observed, different individuals even in the same place and under the same roof exhibit different types. But upon this subject we have no clear information. Nevertheless, whatever may be the cause of this difference, it lays a good foundation for dividing the intermittent genus into dis- tinct species, and the five following are sufficient to comprise all its principal diversities :— 1. ANETUS QUOTIDIANUS. QUOTIDIAN AGUE. 2. ------TERTIANUS. _ TERTIAN AGUE. 3. ------QUART ANUS. QUARTAN AGUE. 4. ------ERRATICUS. IRREGULAR AGUE. 5. ------COMPL1CATUS. COMPLICATED AGUE. As the connexion between all these is peculiarly close, and they occasionally run into each other's province ; and more particularly as the same mode of treatment is common to the whole, it will be most convenient to defer the general history and praxis, till we have taken a survey of these species in their respective definitions and the varieties they often exhibit. It may, however, considerably assist the student, and simplify his pursuit in acquiring a knowledge of their characters, to attend to the three following remarks :— Firstly, the shorter the intermission, the longer the paroxysm. Secondly, the longer the paroxysm, the earlier it commences in the day. 68 HvEMATICA. [CL. 1H.-OR. 1- Thirdly, the more durable the cold fit, the less durable the other stages. Thus, the quotidian has a longer paroxysm and a shorter inter- val than the tertian; and the tertian a longer paroxysm and a shorter interval than the quartan. And thus again, while the quo- tidian has the longest duration, it has the slightest cold stage; and while the quartan has the shortest duration, it has the longest cold stage. It is also the most obstinate to cure. Each of these species, however, admit of considerable variations: for sometimes -we find the paroxysm protracted beyond its proper period ; sometimes anticipating, and sometimes delaying its proper period of return. In other cases, we find each of these species catenated with or giving rise to foreign symptoms or other dis- eases. And we also meet with a peculiar variety of the quotidian ague, in its being sometimes limited to a particular part or organ, in which case it is usually accompanied with very distressing pain. The most irregular of all the species is the fourth, for this is sometimes found to deviate from all the three rules 1 have just laid down; but particularly in the greater length of its interval, which is sometimes double or even treble that of the quartan, whose in- terval of seventy-two hours is the longest of the three more disci- plined species; it is hence found under the various forms of a five- day, a six-day, a seven, eight, nine, and even a ten-day ague ; and sometimes is so extremely vague as to bear no proportion whatever between the violence of its paroxysm, the duration of its stages, and the period of its return. The fifth species is distinguished from the rest by its peculiar complexity, consisting of double tertians, triple tertians, unequal tertians, duplicate tertians, together with as many varieties of the quartan type ; the nature and key of which will be more particu larly noticed under the species itself.

The genuine quotidian is of less frequent occurrence, than the other species ; but it has a considerable resemblance to that variety of the complicated intermittent, which has generally been denomi- nated a double tertian, and with which it is often confounde'd. It is distinguishable, however, to an attentive eye by the regularity of GE. II.-SP. I.]* SANGUINEOUS FUNCTION. 69 its paroxysms, which is true to itself on every return; while in the double tertian the alternate paroxysms only are true to each other as we shall have occasion to observe more particularly in the pro- per place. The quotidian, like the tertian and quartan, has some- times been epidemic. The quotidian intermittent is occasionally limited in its attack to a particular part, and is occasionally connected with other affec- tions. It deviates also now and then from its common rule, in hav- ing an imperfect intermission, and in precipitating or procrastinat- ing every subsequent paroxysm: and hence, affords us the follow- ing varieties:— a Partialis. Partial quotidian. 6 Comitatus. Catenating quotidian. y Protractus. Protracted quotidian. 3 Anticipans. Anticipating quotidian. e Cunctans. Retarding quotidian. In the partial quotidian, the febrile attack is confined to a par- ticular part or organ, and usually accompanied with distressing pain. Under this modification, sometimes one side of the body has suf- fered, while the other has escaped: sometimes one or both eyes; but more generally the whole or half the head, not unfrequently resembling cases of cephalaea, and particularly that species of it which is called hernicrania. In the catenating quotidian, the disease associates with or gives rise to various foreign symptoms or other diseases. And hence, is often found in union with rheumatic affections, particularly lumba- go and sciatica. Sauvages quotes a case in which it associated with daily attacks of a frightful epilepsy* And Dr. A. Munro, in the Edinburgh Medical Essays, narrates a similar instance, though less severe, and alludes to several others that had occurred to him.f Torti has made a collection of numerous examples of this variety, and has united them into one family, under the name of febres in- termittentes comitatae. Galen has described one or two of them under the name of epiala. In the protracted quotidian, the intermission is inordinately short or imperfect. In the former case the paroxysm is lengthened be- yond the usual period of eighteen hours; and in the latter case does so completely subside as to leave the intermission totally clear of febrile symptoms. On which last account the Latins described this variety under the name of quotidiana continua; and the Greeks under that of amphemerina. In the anticipating quotidian, which is the name given to our fourth variety by Dr. Fordyce, the paroxysm precedes its antece- dent period usually by about two hours, and continues the same fore- march at every recurrence; so that the accession may hereby be thrown into any hour of the day or night. * Class ir.

There are few diseases, moreover, in which the quotidian is not occasionally to be found as a symptom ; but it occurs especially in hysteria, catarrh, gout, peripneumony, ischury, quinsy, ana several species of odontia.

The tertian ague, the tritaeus of the Greeks, occurs most frequently in the spring and summer months ; though there is a spurious kind that shows itself in the autumn. The chill, during the cold fit, is intense, with convulsive shivering, rigidity, and gnashing of the teeth. It is, however, of shorter duration than that of the quar- tan, and sometimes passes off in less than half an hour; and is suc- ceeded first by nausea or vomiting, and afterwards by a pungent penetrating heat, frequent respiration, urgent desire for cold drink, wakefulness, and head-ache, sometimes delirium. At length a moisture on the skin, gradually advancing to a copious sweat, breaks forth, the urine commonly deposits a lateritious sediment, and there is often some looseness of the bowels. The entire pa- roxysm sometimes ceases in six hours, but more generally extends to eight or ten ; if it exceed twelve, as it does occasionally in the autumn, the disease forms the spurious tertian I have just alluded to. As the quotidian is mostly common to infants and persons of delicate habits, the tertian chiefly affects those of riper years or of firmer fibres, and especially persons of a bilious temperament. It was the opinion of Hippocrates that the tertian ague, if left to na- ture, would run itself out in seven paroxysms; and Vogel adds, that, when this is the case, there is usually the appearance of a dry scabby eruption about the lips on the fourth or fifth paroxysm. But the period pointed out by the former does not hold in our own day; and the disease has often continued obstinate in spite of cuta- neous eruptions, not only about the lips but over the body. Syden- ham asserts, that in the autumn, in which, however, a genuine ter-^ GE. 1I.-SP.

I he tertian ex- hibits occasionally the two following varieties : x Comitatus. Catenating tertian. C Protractus. Protracted tertian. To both which the explanation already given under the same terms in the preceding species will equally apply. As an associate disease, it is chiefly to be found united with syncopal and soporose affections, indicating some oppression of the brain; or with cholera, or dysentery, mostly indicating irritation or congestion in the liver. It is also to be traced occasionally as a species in syphilis, sea- scurvy, worms, and scabid eruptions. SPECIES III. ANETUS QUARTANUS. <&uman gfgue. INTERMISSION ABOUT SEVENTY-TWO HOURS. : PAROXYSM COMMENCING IS THE AFTERNOON : USUAL DURATION UNDER NINE HOURS. This, which is also the quartana of Celsus, is the tetartaeus of the Greek writers. It is rarely found in the vernal season, but is com- mon in the autumnal; in which quarter, also, it is far the most obsti- nate of all the species, and especially if, as Celsus observes, it show itself only a short time before the commencement of winter. Its chief subjects and sufferers are those of advanced years, and of a melancholic habit; for children and young persons, who principally feel the effects of the two ormer species, are but little obnoxious to it. It commences usually about or a little before five o'clock in the afternoon. The cold fit is less vehement than in the tertian, but of longer duration, and will sometimes continue for two hours, but usually without sickness or diarrhoea. It yields to a heat that is rather troublesome from its dryness than from its intensity, and which is rarely succeeded by a sensible perspiration. There is a heaviness or dullness in the head rather than acute pain; and often during the intermediate days, a sense of soreness over the body, as though it had been generally bruised, which strikes through to the bones. It is here also we principally meet with parabysmic tu- mours, and especially of the spleen and liver: in the former of which organs they are vulgarly called ague-cakes. 72 1LEMATICA. [CL.IU.-OR. I.

ANETUS ERRATICUS. Krvroular &gue. INTERMISSION AND PAROXYSM POSSESSING LITTLE REGULARITY : THE FOR- MER MORE THAN SEVENTY-TWO HOURS. We have already perceived that there is occasionally some degree of irregularity in all the preceding species, least of all, however, in the quartan. And hence all the above might, in such instances, be named erratic. But the peculiar character of the present species is, that the duration of the intermission exceeds that of all of them; on which account it can never be confounded with any of the rest. The chief varieties are the following; which, however might be considerably enlarged, but it is unnecessary. They are principally taken from Sauvages and Vogel: and for other authorities the rea- der may turn to the volume of Nosology. x Quintanus. Five-day ague. |3 Sextanus. Six-day ague. y Septanus.

Several of the above have occasionally persevered with great ob- stinacy ; in some instances for upwards of two years without ceasing. The iast variety is equally irregular as to the violence of its par- oxism, the duration of its stages, and the period of its return. Sereral of Sauvages's species of hernicrania may be properly re- ferred to this place, and especially those, which, by some writers, have been denominated ij^ermittentes larvate, or disguised inter- mittent*. ■E.

There are numerous examples of ague which, to an inattentive eye are as irreducible to any regular order as those which belong to the last variety of the preceding species; but which, when minute- ly examined, are found, however intricate, to be composed of types, not that uniformly resemble each other, but that recur in alternate sets, every set being true to itself, while it differs from that with which it alternates in the duration of its intervals, or of its parox- ysms, or of the time of its accession. And hence, although in some shape or other, most of them return perhaps every day, and are often mistaken for irregular quotidians, they are, in fact, double or triple tertians, or quartans, discovering their real nature by these alternating distinctions. The following are the chief varieties :— x Tertianus duplex. Double tertian. i Tertianus triplex. Triple tertian. y Tertianus impar. Double unequal tertian. 3 Tertianus duplicatus. Duplicate tertian. Quartanus duplex. Double quartan. £ Quartanus triplex. Triple quartan. vol. tt.

A double tertian, taking place as above ; but one of the sets having regularly two parox- ysms on the day of its return, and the other, one alone. The one set evincing a more perfect, the other'a less per- fect intermission. Being a single tertian with two paroxysms on the regular day of attack, the intervals being of ordinary duration. The paroxysms of the one set occurring in the intermissions of the other; and evincing a difference of duration or of violence : with an interval on the third day alone. Consisting of a single quartan with regularly returning pa- roxysms ; while each of the 10 74 HjEMATICA. [cl. III.-OR. I. intervening days is marked with a slighter or separate attack. Consisting of a single quartan; with two paroxysms on the regular day of attack: the in- tervals being of ordinary dura- tion. Consisting of a single quartan with three paroxysms on the regular day of attack : the in- tervals being undisturbed and of ordinary duration. Having thus distinctly noticed the several species and chief varie- ties of intermittent fever, I shall proceed to offer a few remarks upon its general history, and medical treatment. Whenever the accession of an intermittent is violent, be its type what it may, it is sometimes attended with very alarming symp- toms, as syncope, apoplexy, vehement spasms over the whole sys- tem, or a coldness or torpor which threatens death. Yet, when not violent, nor of very long duration, and especially when of the tertian type, it is often serviceable to the general health, and car- ries off many chronic and lurking disorders of other kinds : Dr. For- dyce affirms that he has seen it of considerable use in curing or alleviating chronic rheumatism, habitual indigestion, cutaneous eruptions, protracted inflammations, epilepsies, and hysteria.* And his assertion is corroborated by other authorities.! The duration of intermittents is of great uncertainty. The ver- nal agues generally disappear with the advance of summer: the autumnal are more obstinate, and especially the quartan. Where they have remained long, and have become habitual, even their re- moval must be attempted with great caution; for when abruptly suppressed, they have been known to lay a foundation for a host of other maladies, often of a more fatal description, as paralysis, vari- ous visceral affections, and even sphacelus. Ludolf gives an instance of an eight-day ague (anetus erraticus octanus,) continuing for eighteen years; yet this was probably a double quartan; while we have abundant examples of a continuance of the regular quartan for nine,J twelve,§ eighteen,|| twenty,IF twen- * On Fever, Diss. 11. p. 16. t Salmuth, Cent. 11.

Schenck gives a case of congenital quartan, or in which it ap- peared in an infant immediately after birth ;§ and Paullini another, in which, though not strictly congenital, it appeared in very early infancy.|| But such examples are rare. Among other singularities, I may observe, that, the accession has sometimes been so violent as to destroy the patient in the course of the first paroxysm, of which an instance will be found in Senac,1T while at other times it has been so slight and rapid, that the entire paroxysm has run through its course in a minute.** The character of the intermittent seems in a considerable degree to depend upon the age or idiosyncrasy of the individual and the temperament of the atmosphere. We find also that variations more usually take place in the quotidian than in any other type, which we should, perhaps, ascribe to its occurring more frequently in early life, when the frame is more irritable ; and to the greater debility which the constitution suffers from this type above that of any other, in consequence of the greater length of its paroxysms, and the greater brevity of its intervals, by which means the pros- trated strength of the system has no time to rally or recover it- self. In this metropolis, from causes which have not been handed down to us, and which, indeed, do not appear to have been traced at the time, intermittent fevers were more than ordinarily frequent from the year 1781 to 1785 : and the remarks I have just made apply in an especial manner to all these. As a single example, let us select those of 1782, as described by Sir George Baker and Dr. Reynolds, in an article drawn up by the former with an admirable combina- tion of learning and liberality, sound critical judgment, and inquisi- tive research. " The type of the fever of 1781-2," says Sir George," was either tertian or quotidian; the former being more common in the first * Marcellus Donetus, Lib. m. Cap. xiv. p. 291.—Pontanus, De.

With respect to the former nothing occurred to my observation which is worthy of notice. On the latter, Dr. Reynolds has communicated to me the following remarks : and any addition would be unnecessary relative to a subject which he has so well exhausted."* . . This communication is too long to be copied verbally, but it is fully entitled to the praise which the learned baronet has bestowed upon it. It will be sufficient for our present purpose to transcribe its leading features. Dr. Reynolds, in his communication to Sir George Baker, tells us, that the quotidian fevers of the above year were irregular in their invasion, and uncommon in their appearance ; and that no cases re- sembled each other except in very few circumstances. The first attack generally commenced with a horror; but the subsequent paroxysms, though often beginning with a sense of cold, were chiefly without horror. The intermission was short and seldom perfect. The symptoms were very severe, and in many cases dan- gerous, and leaned strikingly to a typhus form. Great and sudden oppression of the head, anxiety, depression of spirits, a dry, parch- ed, tongue, yet less covered with hardened mucus than might be expected; a pulse-low, quick, and intermitting; bowels variable; urine dark-red, and clear without any sediment, constituted the or- dinary signs. Many had a low muttering delirium ; two or three, a laborious respiration ; a few, spasms and twitchings of the ten- dons ; aphthae appeared occasionally; and one patient exhibited symptoms of violently acute rheumatism. The bark was universal- ly successful; and, " I was as much pleased," says Dr. Reynolds, " with its present efficacy, as I was in the year 1781 mortified by its extraoidinary want of power. Half the quantity of it which I used on that occasion was sufficient on this." In other words, idiosyncracy and atmospheric temperament were both peculiarly visible, and gave a peculiar character, in the one instance to particular cases, and in the other to the general disease. In plethoric habits the head was greatly oppressed, with a tenden- cy to delirum. In those of a nervous or irritable disposition the intermittent was connected with spasms and twitchings of the ten- dons. And those disposed to rheumatism had acute arthritic pains. The state of the atmosphere, and general character of the season Dr. Reynolds has forgotten to notice : but we see evidently and indeed he himself allows, that they gave a typhous impression to the epidemic; which, from the same or from other causes is also peculiarly distinguished by the easy victory it yielded to the use of the bark: as that of the preceding year was distinguished by its ob- stinate resistance to this medicine. If we ascend a year higher, or to 1780-1, we shall meet with an equal diversity of symptoms. " These fevers (intermittents,") says Medical Transactions, Vol. m. Art. xiij. GE. II.-SP. V.] SANGUINEOUS FUNCTION. 77 Sir George Baker, " were in general no other than the common ague ; but in the more inland counties of England, they were often attended with peculiarities extraordinary and alarming. For the cold fit was accompanied by spasm and stiffness of the whole body; the jaws being fixed, the eyes staring, and the pulse very small and weak.—In many cases delirium was added to spasm, under both which symptoms the patient laboured quite to the end of the parox- ysm. And, though the senses returned when the fever subsided, yet a convulsive twitching of the extremities continued even in the intermissions, to such a degree, that it was not possible to distinguish the motion of the artery at the wrist. " This fever had every kind of variety; and whether at its first accession it were a quotidian, a tertian, or a quartan, it was very apt to change from one type to another. Sometimes it returned two days successively, and missed the third, and sometimes it be- came continual. I am not informed that any died of this fever whilst it intermitted. It is, however, certain that many country people, whose illness had, at its beginning, put on the ^appearance of intermission, becoming delirious, sunk under it in four or five days. It is a remarkable fact and very well attested, that in many places, WHILST THE INHABITANTS OF THE HIGH GROUNDS WERE HARASSED BY THIS FEVER, IN ITS WORST FORM, THOSE OF THE SUBJACENT VALLIES were not affected by it. The people of Boston and of the neigh- bouring villages, in the midst of the Fens, were in general healthy, at a time when this fever was epidemic in the more elevated situa- tions of Lincolnshire. It is likewise singular, and worthy of notice, that in many families the female servants were nearly exempted from a disease which very few male servants, especially the la- bourers in the open air, escaped. But the distinguishing character of this fever was its obstinate resistance to the Peruvian bark; nor, indeed, was the prevalence of the disease more observable than the inefficacy of the remedy. Though the quantities of the bark usually given were exceeded, the fit was apt to return, ^rarely altered, either with respect to the time of invasion, or the intenseness of the symptoms ; and just as If no means had been used to prevent it. A drachm of the bark in powder was frequently administered every second hour without averting the fit."* In casting our eyes over the great diversity of medicines that have been employed for the cure of intermittents, we shall find that, innumerable as they are, they may be arranged under two general heads, tonics and antispasmodics; as though, long before the time of Dr. Cullen, his two principals of the disease, debility and spasm, had been uniformly admitted and acted upon. The antispasmodics, consisting chiefly of stimulants, sedatives, and relaxants, have been confined to the term of the paroxysm, with a view to weaken and shorten it; and the tonics, consisting princi- pally of bitters and astringents, have been employed throughout the '■ Med, Tran?. I.uc. citat, 78 HvEMATICA. [CL. III.-OR. I. intervals with a view of fortifying the system against a recurrence of the attack. In discussing the medical treatment of intermittent fevers, it will be sufficient to limit ourselves to these two indications. It was a favourite practice with Bergius to anticipate the cold fit, constituting the accession of the paroxysm, by pungent stimulants, in the hope that if he could successfully combat this first stage, he should gain a complete victory, not only over the individual pa- roxysm, but over all future incursions. His favourite medicines for this purpose were garlic, mustard-seeds, and capsicum, which in his day was described under the name of piper Indicum. And he boasts of having, in numerous instances, completely succeeded with each of these ; though he admits that the mustard-seeds answered best in vernal intermittents, and did not in general prove sufficient for the autumnal quartans. His chief reliance was placed on the capiscum, six grains of which he was in the habit of giving, com- bined with two scruples of bay-berries in powder, "incipiente pri- mo rigore*?' and of repeating it every day, at the same hour for three or four times in succession. And he assures us that he has very frequently seen obstinate intermittents removed by this pow- der, and without any relapse. The practice, however, has not been equally successful in other hands; not even when capsicum has been given in a much larger quantity, or exchanged for ammonia, treacle-mustard (clypeola Jonthlaspi,) or black or white-pepper, the latter of which is only the former denuded of its outward tunic, mixed up with brandy or hol- lands. They have all, indeed, sometimes answered, but the result is uncertain; and, as was long ago observed by the Baron Van Swieten, if the medicine did not succeed upon a full dose, and es- pecially when combined with ardent spirit, it will often extend its influence to the hot fit, and greatly exacerbate it; and not unfre- quently convert an intermittent into a continued fever. Upon the whole,, therefore, this plan is not to be recommended, however va- ried. The least pernicious material is the ammonia, but then it is also the least effective. A large draught of cold water has been not unfrequently had re- course to for the same purpose, and also, in a few instances with success. The object is, by taking it about half an hour before the cold fit is expected, to excite a strong reaction and powerful glow over the entire system against the time when the cold fit returns and thus to pre-occupy the ground; and, by disturbing the regularity of the type, to subdue the intermittent altogether. But this plan has, perhaps, more frequently failed than the preceding : and when the shivering or horripilation produced by the cold water has not been followed with a stimulant effect, as in delicate habits more especially, it has often continued so long as to run into the term of the febrile cold fit, and very considerably to increase its power. Ballonius relates a case in which it proved fatal* * Opp. Tom. k p. 193. GE. II.-SP. V.] SANGUINEOUS FUNCTION. 79 The next division of antispasmodics which have been directed against the paroxysm, and especially against the rigor with which it makes its onset, is sedatives, and of these the chief have been opiates, which, when given in the form of laudanum in a dose of from thirty to forty drops at the commencement of the chill, has, in many cases of intermittents, been highly beneficial; diminishing the duration of the stage, and moderating its symptoms. Dr. Trot- ter says, that he practiced this plan with general advantage in an epidemic intermittent that attacked the Vengeance, one of the channel fleet under Lord Howe: and adds, that, " if the first dose of opium did not produce a sensible relief and exhilaration of spirits in half an hour, he repeated it, and never found it necessary to go beyond a second dose." We have already seen, however, that there is some cause or other, probably the peculiar state of the atmosphere at the time, that baffles on one occasion the remedy that has best succeeded on another. And hence opium has often failed in other intermittents in every form, but especially when given in the cold fit. And ow- ing to this diversity of effect, Dr. Lind thought it most useful in the hot fit; and asserts that, if administered to the extent of twenty or five and twenty drops of laudanum half an hour after the beginning of the hot fit, it produced the advantage of shortening and mode- rating the heat, calmed the anxiety and head-ache which are usual concomitants, expedited the sweating stage, made the paroxysms more regular, and sometimes stopped the fever altogether. Other physicians have commenced with relaxants; and where these are selected, the antimonial preparations are to be preferred to ipecacuan. They tend more directly towards the surface, and, where it is useful to excite vomiting, which is often the case, they act sooner, and maintain the action longer, and hence make a dou- ble effort to accelerate the sweating stage. These preparations differ chiefly from each other by having the reguline part of the antimony they contain in a more or less fusible state ; and their operation will often vary according to the quantity or quality of the acid they meet with in the stomach; and hence the different effect of the same preparation in different persons, and even in the same person at different times. The rubinus antimonii, or antimonial febrifuge of Craanen, was at one time regarded as a specific in in- termittents on the continent, and was in particular favour with Stahl, Dieterech, Vogel, and many other physicia is of reputation ; but it does not appear to be of superior efficacy, in any respect, to the antimonial powder of the London Coliege. The most efficacious practice which I have witnessed, consists in uniting relaxants with opiates; and, where this joint effort is pur- sued, ipecacuan may answer as well as any of the preparations of antimony. We cannot have, for this purpose, a more useful medi- cine than Dover's powder; and it should be commenced with much earlier than is consistent with the usual practice, so as not to re- gulate the hot and sweating stages, but to anticipate the cold fit. 80 HAEMATIC A. [CL* IIL ( And we may still farther add to the ingredients of the medicine a full dose of volatile alkali with great advantage ; for it is in ink form, if in any, that we can employ stimulants with a certainty oi doing little mischief, and very nearly a certainty of considerable benefit. In the case of a quartan in St. Thomas's Hospital wmcn had lasted two years, Dr. Fordyce determined upon this plan ; and prescribed a full dose of Dover's powder with a sweating draught of carbonate of ammonia two hours before the paroxysm was ex- pected. It succeeded perfectly. A profuse perspiration antici- pated the period of the cold fit, and hereby entirely prevented it; bark was next given freely, and this obstinate ague was cured in a few days.* . How far the use of Dippell's or any other animal oil might be serviceable as an antispasmodic in intermittents, I cannot say. Dr. Hoffman was highly impressed in their favour ; and asserts, that a single dose of from twenty to thirty drops, given six hours before the accession of an intermitting fever, will frequently prove a complete cure to th£ complaint. 'J hey appear certainly to be se- dative and diaphoretic, and it is said that the sweat they excite by a single dose may continue for twenty-four hours without languor or debility. As a medicine, these oils have perhaps been thrown aside too hastily. Whatever be the relaxant or sudorific employed, it should be as- sisted by plentiful potations of warm diluents, and by placing the patient between the blankets instead of in the sheets of his bed: for I have already had occasion to observe that upon these auxilia- ry means depend, in many instances, the accomplishment of the object we have in view, without which the most urgent diaphore- tic exerts itself to no purpose. The most important season, nevertheless, for medical operation, is in the intermission of the paroxysms : since, howev er success- ful we may be in moderating the febrile attack, it is rarely that we can depend upon any plan which may then be adopted to pre- vent a recurrence of the fit. The opinion of mankind seems to have concurred in most ages in regarding debility as either the proximate or predisponent cause of intermittents, since almost the only medicines that have been brought forward to guard against the recurrence of their periodic attacks have been tonics, with the sensible quality of bitterness or astringency, or of both. In what way these act upon the moving fibre at any time, and particularly in the disease before us, we cannot say with' any degree of precision. The tone of the moving fibre depends un- questionably in some degree upon the state of the fibrous material itself, but perhaps in a much greater degree upon the quantity or quality of the nervous fluid that issues from the brain and is com mumcated to the fibrous structure, or as it is modified in any par- * Edinb. Med. Comment. Vol. vi. p. 359. GE. II.-SP. V.] SANGUINEOUS FUNCTION. 81 ticular set of fibres. We have great reason for believing that as- tringents, in producing tone, act upon the fibrous material itself, for we find them operating in a like manner upon animal fibres both in a living and a dead condition. But whether, as Dr. Cullen conjectures, it be the part of bitters alone to act upon the nervous power or living principle which adheres to them, and especially in the very singular manner in which he represents them as acting, is a different question; and the present is not the place for enter- ing upon it. If we contemplate the nervous fluid as a peculiar secretion, and the brain as the secreting organ, we can readily conceive that the component parts of this organ as well as of any other, may be invi- gorated by medicines that have a peculiar influence on its struc- ture, and probably concentrate and give tension to its fibres; and that, in consequence hereof, it may be rendered capable of secret- ing its proper fluid in greater abundance, or a more elaborate per- fection. And we can also readily conceive that such effects may be produced by both bitters and astringents, as well as by medi- cines that possess some other sensible qualities, though these are the most obvious in their operation. But should we, with Dr. Cul- len, affirm that the same bitter employed in the same proportion, produces both tone and atony, energy and debility ; that it both cures the gout, and occasions it; that employed for a certain time it effects the former, and after such time, the latter ; and should we beyond this affirm, with him also, that the nervous fluid is not a secretion, but an inherent power of the brain ; that it admits neither of increase, nor diminution ; is changeable in its state, but unchangeable in its essence ; becomes excited and collapsed, or rises and falls in its energy, but experiences nothing of the decom- position or recruit of every other part of the living frame around it; we should travel into a labyrinth of incongruities, and only en- lighten ourselves with a will-o'-the-wisp. Dr. Cullen's system, like himself, is a work of no ordinary stamp ; it is full of immortality, but mixed up with weak and perishable materials. Of the remedies appertaining to the one or the other of the two divisions we are now considering, those of astringents and bitters, the cinchona or Peruvian bark, which unites both qualities in itself, is on every account entitled to our first attention. This valuable medicine, which some practitioners are apt to des- pise or think lightly of in the present day, has never been altoge- ther without its opponents ; and there are many facts respecting its operation, which, if not altogether anomalous, are of very difficult solution. Peruvian bark, according to the authority of Don Joseph Ville- robel, a Spanish physician noticed by Badus, was first brought to Spain in the year 1632; but here, as in every other country, it had for a long series of years to encounter the prejudices of the medical pro- fession; and consequently was very rarely made use of, and unques- tionably would have sunk into oblivion but for the activity of the VOL. II. 11 32 H^MATICA. [CL. IH.-OR- *< Spanish Jesuits, who continued zealously to recommend it, and to import large quantities of it from their brethren in South America. Through these means it was at last recommended by Pope Innocent A. in 1661, as a medicine perfectly innocuous and salutary : and a bcbe- dula Romana, drawn up under the sanction of the physician to bis holiness, pointed out in express terms the time and proportion in which the bark was to be taken. Unfortunately the time stated was frigorc febrili incipiente, " at the commencement of the cold fit; and it being administered in this manner with only temporary be- nefit to the Archduke Leopold of Austria, a year or two afterwards, it immediately fell into great discredit with a very large and learned part of the medical community of Europe ; and a most acrimonious warfare was instantly waged in every quarter on the subject, in which the combatants on both sides seemed more desirous of victory than of truth. In our own country the bark began to become popular about 1655. In 1658, Mr. Underwood, an Alderman of the city of London, died while using it, and was instantly reported to have fallen a sacrifice lo its power; and so prejudicial was the effect of this rumour, that Cromwell, who was attacked with an ague in the same year, was suffered to languish and at length die without an exhibition of the bark, his physicians being afraid to make a trial of it, in consequence of the fatal accidents that had so lately accompanied its use : in the words of Morton, " nondum vires corticis in hoc veneno subigendo,. saltern hie loci, comprobata? erant"* In England, therefore, as well as on the continent, there was a great conflict of opinion. Dr. Prejean, who both preceded and suc- ceeded Dr. Harvey as President of the College of Physicians, ap- pears openly to have advocated its employment in 1658, according to facts adverted to by Sir George Baker in his admirable article on intermittent fevers,! from which these hints are chiefly drawn up. Dr. Brady, professor of physic at Cambridge, appears equally to have countenanced it; as does Dr. Willis according to his own statement; while Dr. Morton professed himself inexperienced upon its virtues, and Dr. Sydenham was decidedly adverse to its use. Sydenham, however, was a man of reason and liberality. His prejudices, and especially those derived from the hypothesis that a fever is a fermentation in the blood raised by nature to throw off some peccant matter at the surface, and which ought not therefore to be checked in its course, however wise it may be to moderate it in its violence, were all at arms against the use of the bark under any circumstances: and the mischievous effects to which he had been an eye-witness in some instances, and its total inertness in more, gave a sanction to suspicion, if it did not justify hostility- But he was determined to watch it for a still longer period through all its variable effects, and to abide by the result when fairly cast *' Pyrctolog. p. 17. t Medical Transactions, Vol. m. Art. xiil 13E. II.-SP. V.] SANGUINEOUS FUNCTION. 83 up. He soon became sensible that it was, in most cases, a powerful engine ; that in many instances it was highly serviceable ; and that in those in which it failed, the miscarriage was rather to be ascribed to some error in handling it, than to a want of power in the drug itself. Sydenham had sufficient ground for this last conclusion. The mode in which it was, at this time, usually administered, was in doses of two drachms given twice in the twenty-four hours; and, as already observed, the time selected for the purpose was during the existence of the paroxysm. It is moreover highly probable that it was sometimes considerably adulterated, from the difficulty of obtain- ing it in any considerable quantity. In 1658, we learn from Sturmius, who warmly patronized its use, that pure bark was so scarce on the continent, that twenty doses of the powder were sold at Brussels for sixty florins for the purpose of being sent to Paris; and that this order so completely exhausted the apothecary's stock, that he himself was incapable of obtaining any even at that price. And hence, for the use of Gne patient, who was attacked with an obstinate intermittent fever in the month of February ef the same year, he was obliged to wait till the June following before he could obtain a supply.* Nor was it less diffi- cult to be procured at Brussels than in many other parts of Europe ; for Bartholine, then residing at Copenhagen, having received as a great rarity a present of three doses, or six drachms, of the powder, from some friends who had brought it from Italy, was induced to make a trial of it on a lady who had a quartan fever. Of this small portion the first dose or two drachms was rejected from the patient's stomach; and, in order to prevent a repetition of this accident, and consequently the loss of his entire stock, the administrator macera- ted his two remaining doses in wine for forty hours, and gave the infusion during two successive paroxysms. The only effect was, that the fever was changed from a double to a single quartan. And here the experimenter was obliged to stop, as having no more materials to proceed with.t But even in 1678, when the same pretext for sophisticating it no longer existed, Morton complains that the bark offered for sale was become so inert, corrupt, and adulterated, that it was necessary to increase the proportion from two drachms, to one, two, or even three ounces for a single dose. And, thus given by wholesale, we cannot wonder that still more mischief should re- sult from its abundance than from its scarcity, whatever might be the purity or impurity of its quality. To guard against all the evils that seemed to accompany its use, Sydenham proposed to himself the following regulations. Firstly, To be peculiarly cautious in the quality of the bark he employed; and to allow of no intermixture, whether from fraud or a view of increasing its virtue. * Febrifugi Peruvian!

' Secondly, To administer the bark in the intervals, instead of in the paroxysms of a fever. . Thirdly, To give it after the rate of two scruples every lour hours, instead of two drachms twice a-day after the Schedula Ko- mana. . -.. , Under these regulations the bark seems to have acquired all tne success to which it has at any time pretended; and modern practice has added little to their value. The most important of them is that which effected a change in the period of exhibiting the bark. But whether the merit of first suggesting this improvement be due to Sydenham, or to some con- temporary of his, we cannot at present very accurately determine. He is, indeed, the only person who openly lays a claim to it, and asserts that he was led to this alteration after deeply pondering the subject—diu multumque apud se agebat: yet Morton who published his Pyretologia in 1692, only three years after the death of Syden- ham, asserts, somewhat loosely indeed, that during twenty or five and twenf^ years* he had been in the habit of giving this antidote, as he calls it, in every season of the year, and to persons of all ages and constitutions; that he had cured every species of intermittent with it quickly and radically; and had found it more expedient to give it in the intervals than in the fits. While Lister, who was contemporary with both Sydenham and Morton, and who treats nei- ther of them with respect, directly accuses Sydenham, a few years after his death, of having copied his mode of giving the bark from the miserable mountebank Talbor, who was its inventor ;—auctore suo, misero illo agyrta. Talbor.t Talbor or Tabor, however, is scarcely open to the stigma of being a mountebank. He concealed, indeed, his preparation of the bark, but he had been regularly ini- tiated into a knowledge of medicine by an apprenticeship to an apothecary at Cambridge ; was the most successful, and therefore the most popular employer of the bark in his day; acquired a high- er reputation in this line of practice than any other individual whatever; was appointed one of the physicians to Charles II. against all the influence of the College ; was specially sent for to Paris to take the Dauphin under his care ; succeeded in curing him; and afterwards divulged his arcanum for a stipulated sum to Lewis XIV. Still, however, under whatever form, in whatever quantity, and at whatever time the bark is given, it is not found to be a specific, not only in every individual, but in every intermittent; and we are hence again driven to a principle I have already ventured to lay down, that intermittents of all kinds are occasionally influenced in their character by idiosyncrasies or the temperament of the atmos- phere. And it is hence of considerable importance to know what other medicines have the strongest claim to attention, when, from accidental circumstances, the best fails of its common effect. * Pa. 114, 132. r M.

V.] SANGUINEOUS FUNCTION. 85 This, as we have already had occasion to observe, was the case in the singular intermittents that prevailed both in this metropolis and in the country in the year 1787, in which the bark seemed to have no energy whatever, notwithstanding that its genuineness was sufficiently tested and proved. In consequence of which the febri- fuge powers of various other medicines were attentively studied and appreciated. In some instances other medicines were mixed with the bark, and seemed to a certain extent to call forth its proper power : a mixture of bark and alum answered in some cases, but produced disappointment in others. " The crude sal ammoniac," says Dr. Petrie, who was physician to the hospital at Lincoln, *' had not a more certain effect. Several women were cured in an hospital by what is called the Dutch remedy for an ague ; which is compounded of the bark and cream of tartar, each two ounces, and sixty cloves powdered. A drachm and a half of this powder was taken every third hour. Yet this likewise frequently failed. We at last thought that we had fallen on a specific in the powder of bay-leaves, plucked from the tree and dried in the shade. It was given from one to two scruples in the beginning of the cold fit. This powder was very efficacious in preventing the fits in many cases, where the bark, in the largest quantity, had been unsuccessful. But almost all who used it had a relapse in the space of a fortnight, three weeks, or a month. One patient, just at the time the fit was expected, took sixty drops of the Thebaic tincture. On this he fell into a profound sleep, sweated profusely, and escaped the fever, not only then but at two successive periods. Eight quartans in the hospital, and four in private practice, were entirely cured by one drachm of the theriaca andromachi, the same of the root of calamus aromaticus in powder, and fifteen grains of salt of tartar. This mixture was taken in warm ale or wine-and-water, an hour or two before the fit.—Nevertheless I must confess that I met with several cases where no medicine prevailed ; and many patients despairing of relief left themselves to nature; some of whom went into a pulmonary consumption, jaundice, or dropsy. Many, whom I thought cured of quartans, lately relapsed. I have now on the hospital books four patients, ill of quartan fevers, who have received no benefit; and I have no hope left but in a long course of deob- struent bitters, and tinctura sacra, aided by the approaching sum- mer."* Morton's medicine, of one scruple of chamomile flowers, ten grains of salt of wormwood, and the same quantity1 of calx of anti- mony, given every sixth hour, is said to have subdued, in the metropolis, an obstinate tertian in two instances. And Dr. Heberden found that two drachms of the powder of myrrh, taken just before the time of the expected fit, relieved a patient from an ague which for a long time had resisted the power of the bark, though taken in very large quantities. *■ Med. Transact. Vol. in. p. 165. 86 HiEMATICA. [CL. HI.-OR. I. The red-bark was now also tried for the first time : it was proved to be of unquestionably superior virtue to that in common use ; but even a moderate dose of it so often oppressed the stomach and excited nausea and vomiting, probably produced by its containing a larger proportion of resin, that, writing at this very period, Sir George Baker tells us, « I have for some time avoided the use of it. Arsenic was also tried in combination with opium. It is admitted that it often effected a cure; but was frequently productive ol violent vomitings, colic, and dysentery. It seems however to have been given at this period in a somewhat rude and unscientific form. " Arsenic," says the distinguished writer whom I have just cited, "is mentioned in books as a febrifuge, but it is one of those substances of which we are not as yet so far masters, as to be able, by any art, to render it transferable from the list of poisons to our Materia Medica; and it cannot be deemed to be a proper remedy for an intermittent fever whilst an intermittent fever is less formi- dable than arsenic." But to this substance we shall have to return presently. If the praxis, therefore, frequently failed which was in use about half a century ago, it was by no means for want of distinguished abilities, great diversity of means, or an ample field for experi- ment. And, although a few other medicines have since been sub- mitted to trial, or some few of the same in improved forms, I am afraid we have no great reason to boast of much clearer illumination or superior success in our own day. * We may not, indeed, be disposed to encourage the farther trial of such operose preparations as milk boiled just seventy-seven times over,* which was one of the most popular charms of the above period; but I have heard of several remedies in high favour and in common use among ourselves, which have as little claim to distinc- tion. The chief bitters that have been called into requisition, indepen- dently of those already noticed, are, gentian, cascarilla, willow- bark, nux vomica, and the leaves of the cherry-bay, or prunus lauro-cerasus: the chief astringents, tormentil, galls and oak-bark ; the bark of both species of the swietenia or mahogany tree ; avens or caryophyllata (the geum urbanum Linn.,) alum, and several of the metallic oxydes. To all these a common remark may be applied, that, where they have been of real service, it has generally, though not in every instance, seemed*to arise from their uniting the two qualities of a bitter and an astringent, and that they have rarely answered where there has been only one of these qualities to depend upon. Thus tormentil, one of the most powerful vegetable astringents we pos- sess, and gentian one of our most powerful vegetable bitters, suc- ceed so rarely alone, that no dependance is to be placed upon them; but when given in combination, they almost rival the virtue of Ephem, Nat. Cur. Dec. m. Ann. vn. vin. Obs. 48. GE. II.-SP. V.] SANGUINEOUS FUNCTION. 87 cinchona ; and have occasionally succeeded where the latter has failed. " Joined," says Dr. Cullen, " with galls or tormentil, in equal parts, and given in sufficient quantity, gentian has not failed in any intermittents of this country in which I have tried it."* There is, however, a principle independently of bitterness and astringency, that seems absolutely necessary to enter into conjanc- lion with these, in order to give full efficacy to any medjcine employed as a febrifuge in intermittents; and a principle that has hitherto eluded all research. For if the cure depended upon the intensity of a bitter and an astringent quality alone, galls, oak-bark, and mahogany-bark ought to succeed better, not only than an union of tormentil and gentian, or chamomile and alum, which have also been found very serviceable, but trrtm cinchona itself; which every one knows they do not do; although, when Peruvian bark cannot be obtained, they become desirable substitutes. The nux vomica, and Ignatius's bean (strychnos nvx vomica, and ignatia arnara, Linn.,) combine, with an intense bitter, a most active narcotic virtue ; and how far the last may be peculiarly opposed to a recurrence of that spasm on the extreme vessels which constitutes the cold fit, it is difficult to determine. M. Bourieut from his own practice strongly recommends the latter, and PaulliniJ and Aaskow§ the former. If Dr. Fouquier's remark be well founded, which we shall have occasion to notice more at large when treating of para- lysis, that these poisons have a power of augmenting energy in de- bilitated muscular fibres, while they leave those in health unaffect- ed, we can account for some part of the success which has been so vauntingly ascribed to them in the case of intermittents. But, notwithstanding that they have been for this purpose before the public for upwards of a century, the infrequency of their use is a strong argument that they are not much entitled to commendation, " In a very small dose," says Dr. Cullen, " the faba Sancti Ignatii has the effect of curing intermittent fevers."|[ But whether he reports this from his own practice, or from that of others, we can- not exactly determine : nor does he tell us what is the small dose he refers to. I have tried the nux vomica to the extent of eight grains in powder every six hours for an adult under palsy, without any mischievous effects except a slight stupor in the head. And much beyond this we cannot proceed with prudence. Hoffman gives the case of a girl of ten years of age, who was killed by taking fifteen grains of it, divided into two doses, for an obstinate quartan.1l The lauro-cerasus was at one time, as we are told by Dr. Brown Langrish, a common medicine in his neighbourhood for the cure of * Mat.

Its properties are nearly the same as those of bitter almonds ; and Dr. Bergius informs us, that he has frequently prescribed an emulsion of bitter almonds with success in intermittents, in the quantity of a pint or two daily during the intermission ; and that it has sometimes cured where the bark had failed.t This is an autho- rity worth attending to; and as the same medicines are said to have a peculiar power of resolving visceral obstructions, they have an additional claim to a cautious series of experiments. It is generally supposed, in the present day, that their poisonous property depends upon their containing a portion of native prussic acid : the taste of prussic acid, however, is not bitter, but sweetish and acrid. Yet it is chiefly the bitter we seem t» want in the present instance ; and if prussic acid really exist in others, and could be separated from the bitter principle from which it appears to be distinct, we might be put into possession of a medicine of considerable importance. The only metallic oxide really worthy of notice is that of arsen- ic ; for although various oxydes of iron, mercury, zinc, and copper, have been tried, and occasionally extolled, none of them have proved so decidedly beneficial as to render it worth while to try them over again. Arsenic, under various forms, has been employed from a very early period.J It is, strictly speaking, an oriental medicine, and has been in vogue immemorially in India, and indeed, all over the east, as a most powerful alterant, as we shall have occasion to no- tice more at large when treating of syphilis and elephantiasis. It was probably introduced into European practice by the medical students under the brilliant caliphate at Bagdad: and seems to have been first appropriated to the cure of intermittents by the Jewish physicians of Poland.§ In Sir George Baker's time, we have seen already that it was in extensive use, but productive of such very different results, that, however successful it might prove occasion- ally, this distinguished pathologist thought it a worse evil than any ague whatever. At that period, however, it does notappear to have been tried in its most commodious forms, which are" those of an ar- senite or arseniate of potash. * M. Macquer recommends the latter; Dr. Fowler, many years ago introduced and gave abundant proof of the utility and general commodiousness of the former; and under this modification it has at length found its way into the Pharmaco- poeia of the London College, under the name of liquor arsenicalis. The cases of success from the use of this medicine are so nume- rous, and its employment is now become so general, as to render it unnecessary to advert to particular authorities in proof of its febri- * Experiments on Brutes.

With many constitutions there can be no question that it disagrees very considerably; and there are numerous in- stances of its failure : but it is a medicine of real and inappreciable value in many diseases, and in none more than in intermitting fe- vers. Dr. Fowler advises it to be taken in doses of from two to twelve drops, according to the age and strength of the patient, once, twice, or oftener, in the course of the day: and the directions are go broad, and at the same time so much within limit, that no* actual harm can occur from following them literally. It will, how- ever, often be found advantageous to combine a few drops of tinc- ture of opium with each dose, to guard against the vomiting and griping which it is sometimes apt to excite ; and the bowels should be kept open by warm aperients during its use. Under the French Directory, a similar preparation of arsenic formed a part of the po- litical constitution of the day ; for an edict was formerly published, commanding that the surgeons of the army of Italy should, within the course of two or three days, cure the vast number of soldiers suffering from agues caught in the marshes of Lombardy, by the use of this medicine, under pain of military punishment. The result of this general survey is, that the cinchona offers by far the best remedy for intermittents of every kind; that arsenic is its best substitute; and that where these fail, as fail they will occa- sionally, or particular circumstances should prohibit their use, we must throw ourselves upon such other medicines as unite intrinsi- cally, or by combination, a bitter and an astringent principle with a certajn proportion of aroma or stimulant warmth. It is at the same time clear that a bitter and astringent principle are, not the only, nor even the most effectual qualities for the cure of an intermittent; for the arsenical preparations contain neither of these in any prominent degree ; while, as already observed, there are many medicines that possess them in far greater abundance than the bark, which have no claim to be put in competition with it as a febrifuge. In effect, of the three species of cinchona used offi- cinally in the present day, the lance-leaved, pale or quilled bark (c. lancifolia,) heart-leaved or yellow bark (c. cordifolia,) and oblong- leaved or red bark (c. oblongifolia,) the yellow, which, as we learn from Mutis and Zea, is the genuine febrifuge of Spanish America, and whose superiority to the rest has been abundantly proved in this country as well as on the continent of Europe, is very conside- rably less bitter and astringent than the red, and not more so than the pale bark: it has less resin than the first,and less gum than the second. Dr. Cullen preferred the red, but Zea's communications upon the subject* were not then published; and he was not in pos- session of the experiments by which the statement of the latter has been confirmed. Sir George Baker, as already noticed, found the red bark produce so much oppression and nausea that he was obliged to discontinue its use. * Annal. de Hist. Nat. Tom. II.

Home has sufficiently shown, not only that the best time for com- mencing the medicine is soon after the paroxysm, but that it should be discontinued some time before a recurrence of the cold fit, since, if persevered in till its accession, this fit is almost uniformly ren- dered more violent* » If in the proportion of half a drachm or two scruples to a dose, as recommended by Dr. Sydenham, or such other quantity as may- sit without uneasiness on the stomach, it should not succeed, it should be tried in combination with some aromatic, or omitted alto- gether ; and by no means be increased to the enormous quantities some practitioners have ventured upon, who seem to have con- ceived that they could force the system to yield to its powers by the overbearing arms of weight and measure. It is singular that Borsieri should have so far lost sight of moderation, as to have pre- scribed occasionally from four to six drachms of the powder in a single draught. In the extremity of the yellow fever such doses have, indeed, been given, and perhaps with advantage, but opium and old port, in large abundance, have been given at the same time. It will also be judicious to abstain from the use of bark in every instance in which any of the abdominal viscera appear to be labour- ing under parabysmic enlargements, whether antecedently to its employment or during its use; and, in these cases, to alternate small doses of calomel, with whatever tonic may be found to agree best with the system. Among the endemic intermittents of the present day that are more particularly worthy of notice, are those which appear in the neighbourhood of Rome, and especially about the Pontine marshes, which have often been drained to carry off the decomposing animal and vegetable materials that spread their aria cattiva, as it is called, over the whole of the Campagna. The disease hence produced is named, from its source, malaria. It is also found in like situa- tions, and has the same name, about Syracuse, and other parts of Sicily. M. Rig'and de l'lsle has asserted, that the miasmic particles which infect the air in these places are heavier than the air in its loftier and lighter strata, and may be separated from it. He tells us that he has found an elevation of 300 yards, at the Pontine marshes themselves, a complete security from infection; and he proposes for those who reside lower to sift the air which they breathe, by wearing a fine silk gauze over the mouth and nostrils.t * Clinical Experiments, 8vo.

In the last, the remission is perhaps more perfect than in either of the others; and it serves to show how little foundation there is for referring all remittent as well as all intermittent fevers to the individual cause of marsh-miasm: for it would be difficult, though, perhaps, not impossible, to find a single example of a genuine hec- tic originating from this source. Marsh-miasm, however, is the most common cause of the second, perhaps of the first species; though we shall presently find it probable that even here, and par- ticularly in the second species, human contagion has also occasion- ally proved a cause, as it assuredly has in those cases of hectic fe- ver produced by perpetually attending upon or sleeping with a con- sumptive patient.

This species occurs most frequently among persons of relaxed fibres, debilitated habits, and sedentary occupations; and is usually preceded by an irregular action of the alvine canal, flatulency, ab- dominal tension, dyspepsy, or some other affection of the viscera of the lower belly. It occurs at ail seasons of the year, but more fre-. 92 HjEMATICA. [CL. IH.-OR. I* quently in the autumn ; the ordinary temperament of the season uniting with the patient's infirm state of health, aud thus adding an exciting to a predisponent cause. Fatigue, cold, or long exposure to the rays of the sun, are also, at this time, powerful concomitants, and quicken the appearance of a disease, the seeds of which have tor some time, perhaps, been lurking in the system. The patient complains of drowsiness, and feels languid ; is occa- sionally chilly, and afterwards flushed, but without perspiration ; tor the skin is hot and dry, the thirst considerable, commonly with nau- sea and a total loss of appetite. In the course of the day, but usual- ly towards the evening the pulse quickens, the heat increases, and at length terminates in a sweat, which, however, is sometimes only partial, rarely free and copious, and never critical: for, on its ceasr ing, the skin is still dry and heated, and the pulse accelerated. Sometimes the exacerbation occurs about noon, and sometimes in the middle of the night. If the disease be left to itself, the symptoms augment in severity daily : the head occasionally, but more generally the liver, or some other abdominal viscus, gives proof of being loaded and oppressed, and the restlessness is intolerable ; or a sudden cholera supervenes, and carries off the complaint by a salutary crisis. This species seems to be primarily dependent upon torpitude, or obstruction in some one or more of the chylopoetic organs, and generally yields to a course of active purgatives, amongst which calomel ought to take the lead. These should be repeated two or three times a week, and the intervals be filled up with mild diapho- retics. The pulse will generally be found from ninety to a hun- dred strokes in a minute; but as soon as it sinks below this, and the heat and dryness of the skin have yielded to a general softness, • columbo alone, or combined with sulphuric acid, will easily com- plete the cure; though the disease not unfrequently runs on for ten days or a fortnight. The remittent fever of infancy, which is generally ascribed to worms, does not essentially differ from the present, regard being had to the greater irritability of the moving fibre in early life. Worms, there can be no doubt, are sometimes the cause of this in- - fantile fever, but perhaps rarely; and there is no instance on re- cord of their having been traced in the bodies of those who have fallen victims to it. Dr. Hunter, indeed, expressly declares that he has often searched in vain. The ordinary cause is, crude accu- mulations in the first passages, whence the digestion proceeds im- perfectly ; there is great general irritation, with considerable lan- guor ; the belly becomes tumid and often full of pain ; the food is nauseated; the head is hot, heavy, and often comatose ; as though there were water in the ventricles, which is sometimes suspected though without foundation; the skin is pale or livid with occasional flushes in the cheeks. It is a singular fact, that if the exacerbation or increase of fever take place in the night, there is wakefulness -and perpetual jactitation; if in the day-time, drowsiness and stupor. GE. III.-SP. I.] SANGUINEOUS FUNCTION. 93 Dr. Butter recommends, as an aperient, small doses of neutral salts, and, when the bowels have been opened, nitrate of potash; or, if there be considerable irritation, the extract of hemlock. Generally speaking, however, there is such a sluggishness in the peristaltic action of the bowels, as well as in the intestinal secer- nents, that neutral salts will not answer the purpose ; and, in conse- quence, rather add to the irritation than carry it off. And hence, much stronger purgatives should be employed from the first; as calomel, resin of jalap, or gamboge dissolved in milk ; and it may safely be prognosticated, that, till this plan is had recourse to, the disease will in most instances maintain its ground if it do not make a fearful advance. But with a course of brisk cathartics, in con- junction with perfect quiet, good ventilation, and light nutritive food, it will usually give way in a week or a fortnight. SPECIES II. EPANETUS MALIGNUS. ^Malignant Remittent. PULSE SMALL, HURRIED, IRREGULAR; DEBILITY EXTREME; OFTEN WITH SIGNS OF PUTRESCENCY. Extreme debility may be inferred from the symptoms of great weakness and irregularity of the voluntary motions; weakness of sensation ; weakness, and wandering of the mind ; weakness of the pulse and of respiration; coldness and shrinking of the extremi- ties ; and a tendency to faint in an erect posture; nausea, vomiting, and a total disinclination to nourishment; difficult deglutition, de- pending upon an atony of the muscles of the fauces; involuntary excretions, depending upon an atony or paresis of the sphincters. A putrescent state of the fluids may be determined from the fol- lowing symptoms : pulse quick and tremulous; heat of the surface sharp and pungent, giving to the finger a peculiar tingling for some minutes afterward ; the skin parched, or soaked with sordid, fetid sweat; the smell offensive to a considerable distance ; the breath hot and fetid; the mouth aphthous; the tongue clammy, fetid, livid, greenish-black ; the lips swollen, puckered, cracked, and purple ; the urine brown or blackish, and offensive ; black discharge often in profuse quantity from the stomach; the stools blackish, colliqua- tive, very offensive, parted with profusely and insensibly; the mind wandering ; twitching of the tendons ; swelling and tension of the belly ; petechial spots, vibices, and hemorrhages from diffe- rent parts, without proofs of increased impetus. This species may be traced under four varieties, each sufficient- ly marked by its own symptoms. 94 H^MATICA. [CL. III.-OR. I- « Autumnalis. Autumnal Remittent. £ Flavus. Yellow Fever. y Ardens. Burning Remittent. I Asthenicus. Asthenic Remittent. The autumnal remittent is that which so frequently shows itself in our own country, in the season from which it derives its name, with a strong tendency to assume the tertian or double tertian type : or, in other words, with striking exacerbations every other day, or, where the double tertian is imitated, every day, the ex- acerbations commencing at noon, and the duration being usually under twelve hours ; the intervals consisting of remissions, which, however, are not always very clearly determined. Where the double tertian type prevails, and the patient has to labour with two distinct sets of tertian exacerbations, it is obvious that one of these must take place every day, as it must occur in the remission of the other. And this variety is, in consequence, often mistaken for a quotidian remittent. But a little attention will point out the real nature of the disease. For while the one set will usually be found distinguished from the other by evincing some difference in its du- ration or its violence, both will be distinguished from the quotidian by the time of their attack, which is at noon, while the quotidian attacks in the morning; and by the comparative brevity of the pa- roxysm, which is always under twelve hours, while that of the quo- tidian runs on towards eighteen. The perfect apyrexy which takes place in the interval of inter- mittent fevers gives the constitution a full power of recovering its energy and recruiting its sensorial supply; and we have hence ob- served, that there is great difficulty in accounting for a return of the paroxysm: I mean in cases in which the patient is removed from the miasmic atmosphere ; for otherwise the cause that com- menced the disease will be present to continue it. Habit may pos- sibly effect this after a recurrence of several paroxysms; but this will scarcely apply to the second, in which no habit can with great strictness of language be said to have taken place. In remittent fevers, however, something of this difficulty is removed, for the constitution even during the remissive interval, is still struggling with disease, and has not an opportunity of recovering its sensorial power. There is no perplexity in accounting for a greater tendency to febrile affections towards the autumn than in any other quarter of the year; and this whether we allow the operation of a specific febrile miasm from marshes or not. When the animal frame has for some months been exposed to the stimulus of a high atmo- spheric temperature, and not unfrequently perhaps to that of the direct rays of the sun, all its organs become relaxed and debilitated. The sensorial fluid is secreted less abundantly, perhaps less elabo- rately ; or, in the language of Dr. Cullen, is in a state of collapse ; a general languor and inertness prevail over every part of the GE. III.-SP. II.] SANGUINEOUS FUNCTION. 95 system, and most of the functions are performed feebly and labori- ously. And hence, if debility be the first stage of the proximate cause of fever, this part of the cause is continually present. But this is not all; the calorific rays of the sun act more powerfully upon some organs than upon others: and most of all upon the liver. The liver is, hence, in a state of perpetual irritation : an unusual proportion of bile is secerned, a part of which is very generally resorbed and carried into the circulation ; and, in tropical climates, so large a part as to form one of the causes of that tawny hue by which the skin is there characterised. And as the greater portion of the surplus often passes off by the bowels, we see an obvious foundation laid for that variety of diarrhoea which we have already described under the epithet of bilious. The liver, moreover, be- comes weakened and torpid in proportion to its degree of excite- ment; and, hence, more disposed to congestion; and t^ere conges- lion or any other obstruction takes place in a large organ, there is instantly a disturbance in the balance of the circulating fluid ; and a disturbance which, in so irritable a state of the general system as we are now contemplating, can rarely exist without fever or a ten- dency to fever. All this mischief is apt to occur in autumns of temperate climates, that are peculiarly dry and uniform in the range of the thermome- ter. But it often happens that, even in the most temperate and healthy climates, like our own, the autumnal months are chequered with sudden vicissitudes of heat and cold : and the pools and rivers are suddenly inundated with equinoxial rains, overflew their banks, and cover a wide surface of land with stagnant water. And the animal frame has, hence, to contend against the dangers of invisible damps, and abrupt changes of temperature, as well as against solar excitement: all which become occasional causes of fever, operat- ing upon a state of body already predisposed to its influence. And, hence, even without the existence of febrile marsh-miasm, we see sufficient causes for a more frequent appearance of fever in the autumn than in any other season of the year. But in many dis- tricts, perhaps even in some sporadic cases, we have reason to be- lieve that marsh-miasm does co-operate, and itself form the remote cause ; and more especially where such cases are frequent, the resi- dence a low-land, and the season hot and rainy. There is still, however, a difficulty in determining why the type of any fever hereby produced should be remittent, rather than in- termittent or continued; and why its declinations should imitate one form of intermittents rather than another. Pathology habits myste- ries as well as every other branch of science ; and let th^nan who would accuse us of ignorance, because we are incapable of explain- ing these secrets of nature, first tell us, to adopt the language of Sydenham, " why a horse reaches his full growth at seven years old, and a man at twenty one ? or, why some plants flower in May and others in June ? If," continues he, " the most learned men are'not ashamed to make an open avowal of their ignorance upon 96 H.EMATICA. [CL. III.-OR. I. these points, I cannot acknowledge myself blamable if I modestly forbear reasoning upon a subject quite as difficult and perhaps alto- gether inexplicable. At the same time I am persuaded, that the progress of nature is as certain and regular in these cases as ini any others, and that the quartan and tertian intermittents are as subject to the natural laws, and as much governed by them, as any other occurrences whatever." . The autumnal remittent commences with lassitude, a general soreness over the body, yawning, inquietude, and most of the other concomitants of a febrile incursion. As some of the larger organs have been more affected by the influence of the season than the rest, we find them giving way in proportion. Hence, the head is sometimes severely tried with pain or heaviness ; the bowels are overloaded with bile, or the stomach is exquisitely irritable, and rejects whajpver is introduced into it. Generally speaking, the sto- mach, from this symptom, suffers more than any other organ ; and, along with the sickness, we have often a very troublesome and de- bilitating looseness which resists every attempt to check its course. Sometimes, however, the bowels are costive from torpor, and the stomach is but little affected. The violence of the symptoms are commonly in proportion to the violence of the incursion; but not the duration of the disease : for I have often seen a fever that commenced mildly and insidious- ly, hold on for upwards of three weeks, whilst another, that com- menced with great severity and threatened the utmost danger, has softened its aspect in a week, and entirely quitted the patient in a fortnight. The exacerbation ordinarily takes place at noon, or early in the afternoon, and consists in an increase of heat and pulsa- tion, for there is rarely any preceding chill, and as rarely any salutary moisture when the heat diminishes. The early part of the night is, hence, peculiarly restless, and no part of it tranquil: the patient doses perhaps for a few minutes, but without being sensible of sleep, and talks incoherently while dosing; the images before him being partly furnished from dreaming and partly from delirium. And even during these snatches of unquiet slumber, he is perpetu- ally turning from side to side in quest of ease, which no position affords him. Every symptom is obstinate ; laudanum rarely produ- ces sleep, and no sudorific perspiration: the coolest and most re- freshing drink is rejected from the stomach ; and if looseness teaze the bowels, it is retained, as already observed, with great difficulty. It is hence of little importance what nourishment is offered, and every preparation seems almost equally to fail in supporting the strength^!" the system. In effect, the debility increases with every fresh exacerbation; and if no favourable change take place before the fourteenth or fifteenth, day there will always be reason for alarm. In the case of a young lady in her seventeenth year, whom I lately attended, the attack was slight, and no serious evil was at first apprehended. The pulse was about ninety in a minute, and GE. III.-SP. I!.] SANGUINEOUS FUNCTION. 97 rather small; the bowels were relaxed, the motions bilious, and the stomach suffered from nausea. A gentle emetic seemed to afford some relief to the stomach, and a dose of rhubarb and calomel to the bowels; but the fever continued with a daily and increasing exacerbation, for the most part at mid-day or soon after. The stomach again became irritable and sick, and the sickness was again connected with a diarrhoea, but the stools was colourless and wafry, and nothing was rejected from the stomach but the diluent food that was swallowed. The skin was now very hot and dry, the pulse from a hundred to a hundred and twenty strokes in a minute, the nights were passed in perpetual jactitation, or in short and talkative dosings. Opium, rhubarb, neutral salts, diaphoretics, and mild astringents, in almost every form and combination, were tried with very doubtful advantage, and the first with evident mischief. Ano- dyne injections were of as little avail; but sponging the limbs with cold water, or brandy and water, which was employed as well dur- ing the remissive as the aggravated symptoms, diminished the pun- gent heat, and for a time afforded some refreshment. Still the fever continued its career; the stomach retained nourishment with difficulty, the bowels were daily teazed with six or seven watry evacuations; the pulse was quicker and weaker, and the nights without rest. The heart at length became oppressed with a sense of fulness rather than of throbbing; the lips were considerably swol- len, ragged and black ; a hemorrhage occasionally issued from the nostrils and the fauces; and the general debility was greatly aug- mented. Such was the appearance towards the eleventh day. The tongue was not much*furred, the pulse, though small, and rarely under a hundred and twelve, was steady; but the heat was intense, and the thirst unquenchable. The mineral acids in dilution, some- times singly, and sometimes in the combined form of aqua regia, with acidulated beverages, were now chiefly trusted to, in connec- tion with farinaceous foods, jellies, and beef tea; and cold water was permitted in any quantity. This plan was continued till about the eighteenth day; when every thing allowed being rejected, and every evacuation accompanied with faintness, it appeared to me that the plan should be changed ; that the chief cause of irritation was at this time debility; and that a more stimulant treatment should immediately be commenced. My colleagues, .for whom I have a high respect, acceded with reluctance, as conceiving that we should only exasperate the febrile symptoms ; and that if the stomach could not retain tasteless things, it would instantly reject wine or convert it into an acid. The attempt, however, was made ; sound old Madeira was administered by tea-spoonfuls, and shortly after- wards a small portion of chicken-jelly. Both remained on the stomach; but the diarrhoea continued; and for this, as modern pre- parations had proved of little use, I recommended a scruple of the confectio Damocratis in half an ounce of cinnamon water after every loose motion. The diarrhoea ceased as by a charm; the ensuing exacerbation was less marked, the night was passed more tranquilly, vol. ir. 13 98 H.EMATICA. [CL.IH.-0R<*' and columbo, in small doses of the powder, was commenced the next morning, and persevered in. The change of treatment, being thus found to succeed, was adhered to, and the patient slowiy effectually recovered. , . . T>..t It is not often that the autumnal remittent is thf °bst.1Dat% *Hl whether there be sickness or not, an emetic should be adimnistereo, as one of the best means of determining towards the skm. Ana singular as the advice may appear, it is rather to be recommenrted where there is little or no sickness than where the sickness is in- cessant ; for in this last case the stomach is often so extremely ir- ritable, that emetics only exasperate it and add to the distress, it will also be useful to evacuate the bowels on all occasions, though the emetic alone will frequently be sufficient for this purpose : and hence Stoll allows of nothing beyond ; for purging, say* he, aug- ments the fever, while an emetic strangles it as at a blow.* The use of the lancet must depend upon the circumstances of the particular case. Where the onset is violent, and particularly where the patient is plethoric or of a vigorous habit, it should be employ- ed instantly and freely; for, without it, from the urgency of the symptoms, there can be little doubt that some large organ or other will soon become locally affected with effusion or congestion, which is always to be avoided as one of the worst symptoms that can oc- cur. And if we have reason to believe that such local affection exists at the time of the attack, and more especially that it be the cause of it, copious depletion will be still more necessary ; for in this case we have not only to contend with the fever, but to guard against phlogosis or inflammation in the infarcted organ. But except in such cases there is no call for the lancet, and we may concede to Stoll that its use is injurious. Copious diluents, and small doses of antimonial powder in effervescing neutral draughts, will ordinarily take off the burning heat of the skin by exciting a breathing moisture; and if this can be maintained through the day, the ensuing exacerbation will probably be mitigated in its violence. If not, eight or ten drops of the tincture of digitalis should be added to the antimonial draught, and all tendency to sickness be restrain- ed by a few drops of laudanum: keeping the bowels in the mean time open with some gentle laxative, as rhubarb, and the sulphate or supersulphate of potash in combination. Blisters are never of service except when topically called for, or as stimulants in the last stage of debility. If the diaphoretic plan fail of effect, and the heat be pungent and augmentive, acids, vegetable, mineral, or both, will ordinarily constitute the best sedatives and refrigerants: and where the debility is extreme, the stimulant plan should be had recourse to which is laid down in the preceding case. One of the severest and most fatal forms under which the malig- nant remittent shows itself, is that of the yellow fever, constituting the second variety of the present species: so denominated from the * Rat.

II.] SANGUINEOUS FUNCTION. 99 lemon or orange hue which is thrown over the entire surface of the body, almost from the first attack of the disease, and' which gives it a distinctive feature. The heat is here also intense, the thirst ex- treme, and the vomiting strikingly obstinate; but not, as in the pre- ceding species, consisting of a colourless material, or the food that has been swallowed, but of a yellowish matter at the beginning and through the height of the fever, and of a chocolate-coloured col- luvies towards its close. The common remote cause of this fever is unquestionably marsh- miasm : and hence it holds a stationary abode in the swampy soils and morasses of the intertropical regions, exposed to a high solar heat, and perpetually exhaling a decomposition of animal and vege- table materials; and is found occasionally in all climates that make an approach to the same character: where, in the language of the poet, The rivers die into offensive pools, And, charged with putrid verdure, breathe a gross And mortal nuisance into all the air. And, as almost every territory in which it has committed its rava- ges has given it a new name, it is as gorgeously arrayed with titles as the mightiest monarch of the east. From the depredations it has committed in the West Indies and on the American coast, it has been called the St. Domingo, Barbadoes, Jamaica, and American fever: and, from its fatal visitations on the Guinea coast and its adjoining islands, the Bulam fever. In British India it is distinguished by the name of the jungle-fever, and still further to the east by that of mal de Siam, Nearer home, in the lowlands of Hungary, and along the South of Spain, it is called the Hungarian or the Andalusian pesti- lence. From its rapid attack on ships' crews that are fresh to its influence, the French denominate it jfiivre matellotte, as the Spanish and Portuguese call it vomito prieto, or black vomit, from the slaty or purplish and granular saburra thrown up from the stomach in the last stage of the disease ; while, as its ordinary source is marsh- lands, it has frequently been named paludal fever. Its more com- mon name, however, in the present day, and for the reason already assigned, is yellow fever: and, when the attack upon new-comers is slight, seasoning. From its showing itself in so many parts of the world, and under circumstances so widely different, it is not to be wondered at that it should often be accompanied with a considerable diversity of symp- toms ; and consequently that the paludal fever of one quarter should be regarded by many writers of considerable authority as essential- ly different from that of another. But an attentive perusal of the origin and laws of febrile miasm, as I have endeavoured to explain them, when treating of the remote cause of fever,* will, I trust, be sufficient to account for all such local distinctions; and, if not to * Vol. ii. p. 55. * 3. 100 HjEMATICA. [cl. iil-or. I. prove, at least to render it highly probable that they depend " part- ly upon the state of the body at the time of attack, but chiefly upon some modification in the powers or qualities .of the febrile musm itself, by the varying proportions of the co-operative agents of mois- ture, heat, stagnant air, and other auxiliaries which have not yet been detected, in their relation to each other in different places and seasons." How far the yellow fever is capable of origination from any other cause than febrile miasm from marshy lands, we cannot at present determine. When, however, it has once firmly established itself and raged with severitj, it is now very generally admitted that the effluvium from the body of the affected " is loaded with miasm of the same kind, completely elaborated as it passes off,"-—and'that the disorder is from this time capable of communicating itself by con- tagion. And, from the statement already given,* it appears far more probable that the fever at Cadiz in 1800, and that at Malaga in 1803, had their origin in contagion, or, in other words, in febrile miasm produced by a decomposition of the effluvium from the hu- man body, than from the same miasm issuing from a decomposition of marsh-lands. And on this account I have rather preferred the trivial name of yellow to that of paludal fever, which is too limited to express its source in every instance. From the different impressions produced on febrile miasm under these diversities of origin and adjuncts, we find, independently of other discrepancies, that the fever it -excites sometimes assumes a caumatic or inflammatory cast, sometimes a typhous, and sometimes a synochous, or, in other words, begins with the first and runs rapid- ly into the second or third. Generally speaking, the variety before us evinces the last of these characters, as does also the variety we have just treated of: the two varieties that yet remain will afford examples of a typhous and inflammatory bearing. Its ordinary progress amongst those who are fresh to the tainted atmosphere is thus accurately described by Dr. Moseley, who, from its resemblance to the causus of Hippocrates, denominates i't endemi- al causus. " When a new-comer is seized with a sudden loss of strength, and a desire of changing, for rest, into every position with- out finding it in any, those symptoms which constitute the endemial causus may be expected. The following day, but sometimes within twelve hours from the first indisposition, the violence of the disease will commence thus: There will be a faintness and generally a gid- diness of the head, with a small degree of chilliness and horror, but never a rigor. Then immediately will succeed a high degree of fever with great heat, and strong beating in all the arteries of the body, particularly observable in the carotid and temporal arteries; flushings in the face; gaspings for cool air, white tongue, but tinged with yellow, after the retchings have commenced; excessive thirst, * Vol ii. p. 53. GE. III.-SP. II.] SANGUINEOUS FUNCTION. 101 redness, heaviness and burning in the eyes ; heaviness and darting pains in the head, and small of the back, and often down the thighs; pulse quick, generally full and strong; in some cases quick, low, and vacillating; *k:n hot and dry; sometimes with a partial and momentary moisture; sickness of the stomach from the first, which increases with the disease ; and, immediately after any thing is taken to quench the thirst, retchings succeed in which bilious matter is brought up ; anxiety with stricture, soreness, and intense heat about the praecordia; great restlessness ; heavy respiration ; sighing ; urine deep-coloured, and but little in quantity. This is the first stage of the fever; and may continue twenty-four, thirty-six, forty-eight, or sixty hours, and this constitutes its inflammatory period. " The second stage begins with an abatement of many of the pre- ceding symptoms, and the rise of others: sometimes with a deceiv- ing tranquillity, but with perturbation if the patient should fall into a sleep : then a yellow tinge is observed in the eyes, neck, and breast; the heat subsides, and sometimes with a chilliness; but not with that sort of strong rigor which,-when it happens, terminates the disease by sweat, or by copious, bilious evacuations upwards or downwards. The retchings are violent and turn porraceous; the pulse flags, but is sometimes high and sometimes soft; the skin soft and clammy; the urine in small quantity, and of a dark croceous colour; the tongue in some cases is dry, harsh, and discoloured; in others, furred and moist; there is confusion in the head and some- times delirium; with the eyes glassy. This stage of the disease sometimes continues only for a few hours, sometimes for twelve, twenty-four, thirty-six, or forty-eight hours, but never longer. " In the third and last stage of the fever, the pulse sinks and be- comes unequal and intermittent, sometimes very quick; frequent vomiting with great straining and noise in vomiting, and what is brought up now is more in quantity, and has the appearance of the grounds of coffee, or is of a slate colour. Nothing can be retained in the stomach; difficult breathing; tongue black ; cold clammy sweats; eyes hollow and sunk ; yellowness round the mouth and temples, and soon after over the whole body." These symptoms become gradually more aggravated, accom- panied with subsultus tendinum, black urine, deadly coldness of the limbs; delirium, faltering speech ; hemorrhage, or oozing of blood from the mouth and nostrils, corners of the eyes and ears; black bloody vomiting and stools; vibices, hiccough, muttering, coma, death. * After the first prostration of strength, the disease runs on violent- ly till the sensorial power is exhausted. Through its entire course, till the patient is sinking, the intellect is not particularly disturbed, and the organs chiefly affected are the abdominal; those which, for reasons already assigned*, principally suffer in the malignant au- tumnal remittent of our own country ; more especially the stomach * Epanetus malignus, Vol. n. p. 139. 102 HiEMATlCA. [CL. 1II.-OR. I- and the liver. Hence the intense heat and anxiety about the prae- cordia, the saffron dye of the urine, the yellow tint of the skin, ana the vomitings first of a bilious and afterwards of a chocolate or san- guineous colluvies. , . In some cases the disease opens with great vehemence, and rusn- es forward at once to its acme, constituting the second stage oi ur. Mosely. The patient is sometimes cut off in four-and-twenty houis and, from the violence so suddenly committed on the liver, its pro- per function is instantaneouly suspended, and, instead of an exces- sive emulgence of high-tinted bile, a chlorotic secretion takes place, which, forced into the sanguineous system, gives a ghastly Uvidity to the entire surface. Shortly after which, if the patient live long enough, the gorged blood-vessels of the inflamed and gangrenous liver itself, and sometimes also of the spleen or stomach, give way, and repeated tides of dark granulated grume, like the grounds of chocolate, are ejected by the mouth. Mr. Pym has very forcibly described this overwhelming onset of the disease in the following terms: " There is at the first attack a peculiar shining or drunken appearance in the eyes; the head-ache is excruciating and confined to the orbits and the forehead; has no remissions; when it terminates favourably, is rarely attended with yellowness of the «kin, which, if it do take place, is of a very pale lemon colour. It runs its course from one to five days, is attended with a peculiar inflammation of the stomach, which, in most cases that prove fatal, terminates in gangrene, or in a diseased state of the internal or villous coat of that organ, accompanied with a vomiting of matter resembling coffee-grounds, and a livid or putrid appear- ance of the countenance which it is impossible to describe ; but those wishing to form an idea of it may see its fac-simile in the countenance of any person with a florid complexion, during the burning of spirit of wine and salt in a dark room, as is practised in the game of snap-dragon during the Christmas gambols."* In this state the disease is unquestionably contagious: and as Dr., Cullen has laid down contagion as a distinctive character of fevers originating from human effluvium, in contrast with those originating from the effluvium of marshes, Mr. Pym has endeavoured to draw a line of distinction between yellow fever in this state of intensity and in its ordinary career; contending that the former (to which he limits the name of Bulam fever) is in every instance derived from human effluvium, and consequently that the two must of necessity be distinct diseases. And to make the distinction still clearer, he has ventured to assert that the symptom of a more pallid or bloated countenance, together with that of black vomit, or the discharge of coffee-like grounds from the stomach, is peculiar to the contagious fever, and is rarely if ever an attendant on that produced by marsh- miasm even in its most impetuous and fatal course. This distinction, however, is in both instances at variance with * Observations upon the Bulam fever, &c. 8vo. 1815. BE. III.-SP. II.] SANGUINEOUS FUNCTION. 103 the history of the disease as it has occurred in most other parts of the world, and more especially with respect to the symptom of black vomit, which in its last stage or severer incursions, is common to it from whatever source derived. It occurred more especially in the fatal epidemic of Antigua in 1816, which was decidedly an off- spring .of marsh-effluvium. The island had for some years, observes Dr. Musgrave,* at whose description we have already glanced slight- ly, been peculiarly healthy: and the disease first showed itself in a swampy part of it, and amidst new-comers who were sailors, but from a healthy ship, and themselves in good health on first landing. It soon spread widely, and a't length indiscriminately among all ranks and conditions, and situations—among blacks and whites, the newly arrived, and the oldest settlers in town and country. Nothing was better calculated than this fever to show that al- most all the different kinds of fever that occur to us, are capable of issuing from a common source or miasm, merely modified by con- tingencies : for in Antigua they all occurred in different individuals. The disease sometimes commenced as an intermittent or remittent, and sometimes in a continued type ; it sometimes ceased in four or five days, which was its usual course, and sometimes terminated in an intermittent. The head was in some cases chiefly affected ; in oth- ers the stomach, liver, or some other organ : sometimes the patient died without hiccough or black vomit, though he rarely recovered where these symptoms appeared ; Dr. Musgrave recollects but one instance. Recovery was no exemption against a second attack. In new-comers the tint was of a lemon hue; in native or assimilated constitutions, of a deep orange. The state of the atmosphere at the commencement of the disease presented nothing peculiar. In the midst of the discrepancy between these two accounts, there is still much that is concurrent, and quite enough to establish the identity of the two diseases, if an abundance of other evidence to the same purpose were not at hand. The fever of Mr. Pym, speci- fically characterized by black vomit, is represented as being pecu- liarly dangerous and fatal; in that of Dr. Musgrave, this symptom only occurred in the most dangerous cases of the malady. Accord- ing to the latter, the severest and most deadly attacks were amongst the new-comers; the mildest, amongst the natives or those whose constitutions were assimilated to the climate. The yellow hue of the former (and I have already endeavoured to account for this) was of a deep orange, that of the latter, a lemon colour. Mr. Pym describes three species of fever as common to warm climates, but which dif- fer from each other in their mode of origin, and diagnostic character. In that of least danger, the colour of the surface, he tells us, is of" a very deep yellow ;" in that of higher danger, it is of " a deep yellow ;" and in the disease before us, which is by far the most fatal, where there is any yellow at all, it is of " a very pale lemon colour;" which * Medico-Chirug. Trans. Vol. p. ix. 92. 104 ILEMATICA. [O- HI.-OR. I- is, in effect, the very hue ascribed to the severest cases of the Anti- gua fever by Dr. Musgrave, as the " very deep yellow," or " or- ange," is to the mildest. So that, examined by their external livery as well as their internal disorganization, there can be no doubt that the two diseases are the same. Mr. Pym appeals peculiarly, as a distinctive character of the Bulam fever, to the deadly and chlorotic paleness exhibited by the countenance, in its latest stage, or most fatal incursion. But" even this only shows that, in such case, the disease makes a mortal attack upon the larger viscera, and especially the liver, from the first; and demonstrates the proposition I have ventured to lay down, that in proportion as this organ is severely affected is its inability to secrete proper bile or indeed bile of any kind: and, consequently, that if the irritation only reach a certain point, the secernents will be stimulated to emulge a larger quantity and of a deeper hue; a considerable portion of which, in conse- quence of such irritation extending to the neighbouring absorbents, will be sent back into the sanguiferous system, and produce the orange tinge, which, in the description of both these writers, pecu- liarly marks the disease before us in its less fatal attacks. While, if the febrile incursion be so violent as totally to derange the function, and still more the structure of the liver, no. bile will be secreted at all, or if secreted, less in quantity and consequently less diffusive in col- our ; and hence only conveying a chlorotic or livid tinge to the face, which at the same time exhibits a bloated fulness from effusion or debility of vascular action. Yet, after all, it is not denied by Mr. Pym, nor, so far as I know, by any of the writers on the American or Andalusian fever, that the yellow fever from marsh-miasm ever evinces either of the symptoms that are so essentially ascribed to the bilious remittent produced by contagion, but only that "it is rarely, if ever," to adopt Mr. Pym's own words, " attended with the fatal symptoms peculiar to the Bulam fever, viz. the black vomiting, and a peculiar bloated appear- ance of countenance." There would, however, be an almost insurmountable difficulty in reconciling these different descriptions of the same disease, in con- sequence of Dr. Musgrave's telling us, very decisively, that not a single instance occurred in the Antigua fever of its being received by contagion, were there not strong reason for believing, as I have already observed on another occasion,* and hence need not go over the ground again, that this explicit writer suffered himself to be deceived upon this point; most probably, like Mr. Pym, from too close an attachment to the doctrine laid down by Dr. Cullen that the fever from marsh-miasm does not produce contagion, which is speci- fically a result of a fever from human effluvium. It is impossible to peruse the history of bilious remittents in warm climates offered from all quarters, without seeing that it may and does originate from both sources ; each sometimes operating alone * Vol. a. p. 47. GE. III.-SP. II.] SANGUINEOUS FUNCTION. 105 and sometimes in conjunction with the other, as was probably the case at Antigua, and certainly the case in the yellow fever that raged at Philadelphia in 1793 ; in which, says Dr. Rush, there were for several weeks two sources of infection, viz. exhalation and contagion. The exhalation infected at the distance of three and four hundred yards ; while the contagion infected only across the streets. The more narrow the streets, the more certainly the contagion infected. Few escaped it in alleys. After the twelfth of September, the atmosphere of every street in the city was loaded with contagion; and there were few citizens in apparent good health, who did not exhibit some mark or other of it in their bodies, particularly a preternatural quickness in the pulse, " which occurred in negroes as well as in whites; and in a few who had had the disease before." That febrile miasm produced from human effluvium is less volatile than that from marsh-miasm, and consequently more limited in its range of infection, is consistent with common observation, and a fact I have already endeavoured to explain. It is sufficient to observe, on the present occasion, that the disease thus issuing from two distinct sources was one and the same in its general symptoms, and yielded to a like treatment: thus establishing satisfactorily, what indeed Dr. Rush himself does not seem to have apprehended, that, though remotely issuing from two distinct sources, it was imme- diately excited by a common miasm thus doubly generated, and which was only modified in its action by the nature of its origin, or by contingent powers. Unfortunately the practitioners in warm climates have differed as much in their therapia as in their etiology : and apparently the cause that has produced the one has produced or greatly influenced the other. Mr. Halliday alarmed at the debility which the system will have to encounter in the second stage of the disease, or as soon as it has run through its inflammatory career, shuddered at the thought of the lancet; commenced with slight purgatives of sulphate of magnesia and manna, and immediately afterwards had recourse lo the bark. The practice of Dr. Hillary was something less timid ; for he allowed an abstraction of from twelve to twenty ounces of blood on the first, and even in a few cases again on the second day, according to the patient's strength and constitution. While Dr. Rush, on the other hand, regarding the inflammatory impetus as the sole cause of danger, boldly resolved to lay prostrate if possible the morbid Hercules at its birth, by bleeding, according to the state of the pulse, two or three times a-day during the first two days, and by following up the same plan, as long as a single germ of an inflam- matory diathesis should continue manifest. " 1 paid no regard," says he, " to the dissolved state of the blood, when it appeared on the first or second day of the disorder, but repeated the bleedings afterwards, in every case, when the pulse continued to indicate it,. It was common to see sizy blood succeed that which was dissolved. The dissolved appearance of the blood 1 supposed to be the effect of vol. ii. 14 106 hjsmatica. [cl. m.-oR. *< a certain action of the blood-vessels upon it. The presence of petechia? did not deter me from repeating blood-letting where_ the pulse retained its fulness or tension." And he affirms, that both petechiae and vibices disappeared in various cases alter bleeding. This plan he often pursued through the fifth and even the seveQ"| day, in the course of which period, from a hundred to a hundred and twenty ounces of blood were frequently taken away by six or eight applications of the lancet. , His purgative plan was not less alert. Ten grains of calomel and fifteen of jalap, was the force with which he opened his remedial attack, and which he repeated every six hours, till the alvine canal was effectually evacuated. This mode of treatment, he tells us, he was led to by accident; and with it he became as successful as he had been unsuccessful under the tamer and more established method. Yet it is the boast of those who have pursued this tamer, and formerly more established method, that, though quicker and less striking, it has, in the general balance of the account, proved more salutary than the formidable plan of their antagonists. There is not, however, necessarily any opprobrium medicorum in this discrepancy ; for it is probable that in different situations or under different circumstances, both plans have been equally judi- cious and equally successful; for we have seen that the disease under different incidents and coadjuvants has exhibited every variety of violence, and inclined to almost every variety of febrile type. Where there is not much impetuosity in the onset, no great derange- ment or prognostic of inflammatory congestion in the larger viscera, where the remissions are regular, and the epidemy is pretty uniform in its character, large and repeated bleedings, as a general rule, must prove mischievous. They will not shorten the career of the disease, but they will convert the remittent into a continued fever: and we shall in the latter stage of its course stand woefully in need of that strength which we shall have squandered away at first, if we have commenced with profuse venesection. On the contrary, if the disease make its incursion with great impetuosity; if the pulse be full and strong, or even if it be only hard, and there is great tendency to inflammatory congestion in any of the larger organs, as the head, the chest, or, as is far more common, the stomach, the spleen, and the liver, we cannot well be too bold both in bleeding and purging; and the plan laid down by Dr. Rush is by no means an exaggeration of what ought to be pursued. It may be, that eight-and-forty, or even four-and-twenty hours are the whole we have to work in; and unless we can, so to speak, stifle or lay prostrate the sensorial power, and thus com- pletely break down Jhe inflammatory diathesis by debilitating and relaxing the living fibre or solidum vivum, rather than by diminish- ing the moles movenda, the organs mostly affected will in all pro- bability become gangrenous in a day or two, the oppressed blood- vessels will give way, and we shall have a chlorotic or livid skin, cold extremities, black vomit, and all the other apparitors of death. GE. 1II.-SP. II.] SANGUINEOUS FUNCTION. 107 before the tamer plan of aperients and diaphoretics could have time to produce the slightest impression on the system. Generally speaking, it will be best to bleed in an erect position, for the sen- sorial excitement, which is what we are chiefly to aim at, is best cut down by syncope, which an erect position will soonest induce ; and we may, hence, save the expense of several subsequent bleedings. There is no doubt that by a praxis thus active and resolute, very vehement attacks of the yellow fever have sometimes been subdued ih a few days. But let not those who have thus triumphed conceive that by the same process they would have as soon put to flight less violent incursions of the same disease that have been treated in a different manner ; for the more acute the disease, the shorter its duration, in most instances; and hence, had no medical treatment whatever been resorted to, the fever might have run through its course, whether fatally or happily, in a less period than if it had commenced more leisurely and insidiously. Yet it is very far from being always that an early return to health is the consequence of this daring practice, however judiciously it may be had recourse to, and though it may have been the only means of rescuing the patient from death; for the double debility induced by the disease and its remedy have often laid a foundation for dropsies and other cachexies, which have required years to master, and which have sometimes never been mastered at all. Dr. Pinckard, in his " Notes on the West Indies," has given a very interesting description of his own sufferings under this disease, and of the remedial process to which he had recourse. His attack commenced in the more common manner, slowly and insidiously, and demanded eight or nine days to reach its acme. His head, stomach, and at last his bowels, were severely affected, especially the first; but his intellect continued sound; and, though the symptoms were vehement, there seems to have been little tendency to that violent visceral inflammation which in the stage of debility is so apt to produce gangrene ; and consequently he had no black vomit. He lost twelve or fourteen ounces of blood at the commencement of the disease, and took a strong dose of calomel, which considerably relieved the pain in his head and eyes, and diminished the restless- ness ; but the thirst, heat, and dryness of the skin were still intense; and his weakness became extreme. Affusions of cold water, old hock, opium, and bark, were made use of in profusion, and each seemed to afford great relief. Yet on the subsidence of the fever, he represents his feebleness as most deplorable, and such as it appeared impossible to recover from. Here a mere use of the lancet could have been of no avail, and, had not the author most judiciously forbade its further employment, in all probability he would never have been the historian of his own case.* Mr. Pym speaks with a very just discrimination upon this subject, in observing, that while the Bulam fever, or the disease in its most *' Vol. in.

IH.-OR. 1. violent attack, is relieved by free venesection, the yellow fever more properly so called from the brighter hue on the surface, or, in other words, that which is slighter in its incursion, will not often endure the lancet. Dr. Musgrave's statement seems to oppose this assertion, for he distinctly tells us that " blood-letting in both forms is our sheet-anchor; the only pillar on which we can securely rest any hope of extensive success " The Antigua fever seems to have exhibited great severity in most instances, and hence called tor a courageous course of practice with perhaps few exceptions. Yet the following paragraph proves that it did admit of exceptions, and softens down almost to unanimity a clash of opinion and mode of cure which after all is more ostensible than real; " we have repeat- edly," says he, " with success taken upwards of forty ounces of blood at one bleeding. With equal success we have in several cases renewed the bleeding up to the third, and even the fourth time $ but generally speaking those which require such reiterated evacuation, evince an obstinacy not likely to admit of a favourable RESULT UNDER ANY MODE OF TREATMENT. It MIST ALSO BE REMEMBERED THAT EVl.RY ONE WHO APPLIES FOR ASSISTANCE IS NOT ALIKE ABLE TO BEAR this liberal depletion." It only needs to be observed further, that the bowels were emptied as they ought to be by calomel or jalap, or some other active purgative ; the head was shaven, and cold ablution preferred ordinarily to cold affusion, because of the fatigue endured under the latter. Bark was then instantly given, and, where the stomach would bear it, in the powder. Mercury, with a view of exciting salivation, was seldom tried, and not relied upon. In effect, in the milder cases it is not wanted for this purpose, and, in the more urgent, there is no time for its use. r There is another variety of malignant remittent which has been known to medical practitioners from the time of the Greeks, though less frequent than the yellow fever, and which, by Hippocrates, has been denominated causus ; as it has by later writers, who have only translated the Greek term, been called " febris ardens, ardent or burning remittent." In Hippocrates it is briefly described as a fever, characterized by extreme heat, violent thirst, a rough and black tongue, complexion inclined to yellowish, saliva bilious. There is commonly an acute aching in the head, nausea, great anx- iety of the praecordia, with frequently a gnawing pain at the sto- mach. The bowels are unusually costive, particularly at the com- mencement of the disease. The tongue, mouth, nostrils, and, in- deed, the whole surface of the body is parched and fiery-hot, whence, indeed, the Greek name for the disease ; the pulse is full and strong: the voice hoarse ; the breathing short and quick, with sometimes a slight cough, and occasionally delirium : Dr. Moseley conceived it to.be the yellow fever we have just described ; to which, indeed, it makes, a near approach, though it has several dis- tinctive symptoms. The burning heat is more intense, the thirst more intolerable ; while the stomach is less irritable ; and will bear vomiting with advantage: there is no black vomit at any time : GE. III.-SP. II.] SANGUINEOUS FUNCTION. 109 and, in the second stage, the chilliness which, in the yellow fever, is merely accompanied with horripilation, and is a mischievous symptom, in the causus is accompanied with a smart rigor which terminates in a copious and salutary sweat. The attack moreover seldom lasts more than four days: and is usually terminated by a critical diaphoresis, vomiting, diarrhoea or nasal hemorrhage: and, if these do not carry it off, it generally proves fatal. It chiefly attacks the young and the vigorous, who bear the at- tack better than old persons. The causes to which it was former- ly ascribed, are, long exposure to the heat of the sun, great fatigue fron^undue exercise or labour, or too heating a diet. It has of late, however, been supposed, and with much plausibility, from its fre- quent occurrence towards the autumnal equinox, and especially from its resemblance to the yellow fever, that, like the latter, its or- dinary remote cause is the miasm of swamps and marshes. And, if so, it affords us a proof that, under certain modifications, febriie mi- asm issuing from this source, may, as I have already suggested, pro- duce a caumatic or inflammatory, as well as asynochous or typhous tendency, in constitutions predisposed to this character of fever : for the causus is, in fact, whatever be its cause, a vehement inflamma- tory remittent; and hence its treatment is not difficult. Bleeding and purging are here unquestionable. And, when these had been carried to a sufficient extent, Hippocrates added the use of cold ap- plications in every way; the coldest possible drinks; the coldest possible clysters, and ablution with cold water applied to every part of the body.* Under proper regulations there is no doubt of the advantage of such a treatment, and the medical records of the continent, as well as of our own country, throng with cases in which it has been found serviceable. Marquet recommends the application of cold air as well as of cold water; and gives an instance of a ra- pid cure in one who in a state of delirium exposed himself naked to the cold of the atmosphere out of doors.t And on this account Schaffer advises that the patient, in any acute fever accompanied with dry burning heat, should be carried forth from his chamber, on a mattrass, and thoroughly ventilated abroad.J In the preceding varieties, the malignant remittent has shown a tendency to an inflammatory or a synochous career. Under parti- cular circumstances, however, it evinces a like inclination to a deep nervous depression, sensorial debility, or a typhous character from the first. And this, whether the febrile miasm originate from a decomposition of marsh, or of human effluvium ; for the records of medicine furnish us with innumerable instances of both. In the two cases, however, there are a few slight variations in the range and mode of its action, the laws of which 1 have already endeavour- ed to lay down as far as we are acquainted with them.§ This mo~ * Tlty Ilaiw p. 518, 1. 48. 51. p. 419. 1. 37. t Observations sur la Guerison de plusieurs Maladies. t Versuche. i. p. ltS4. $ Vol. II. p. 53. 110 HJEMATICA. [CI" 11I•"-, dification of the disease, therefore, is best distinguished by the name Of ASTHENIC REMITTENT. The epidemics of this kind that are accompanied with most mor- tality are those which arise from a decomposition of human effluvi- um in the midst of filth, poverty, or famine, great heat and moist- ure, crowded multitudes, and a stagnant atmosphere : for here we have almost all the auxiliaries of febrile miasm operating for its production. The remittent epidemics of Cadiz and Malaga seem chiefly to have been of this kind : and they are the common pesti- lences of dis-spirited armies, maintaining their ground with difficul- ty in the midst of great carnage, surrounded by the dead and the dying, reduced to short provisions, and worn out by the fatigues of the campaign. The writings of Sir John Pringle are full of exam- ples of this kind ; and Professor De Haen has given a striking de- scription of the same in his account of the contagious epidemy that committed such tremendous havoc throughout the Prussian army, at Breslaw and its vicinity, in the middle of the last century, constitu- ting the disease to which M. de Sauvages has given the name of tritaeophya Vratislaviensis. It was peculiarly distinguished by ir- regular action, great debility, and overwhelming dejection of mind. The lipyria, or coldness of the surface, with which the disease opened, rarely yielded to any general re-action, for the extremities seldom became warm, and were often rigid and convulsive; at the same time that the interior parts burned like a fire; the head and stomach suffered with acute pain ; there was great anxiety about the praecordia ; and so exquisite a soreness over the entire surface that the patient had the greatest dread of being exposed to the con- tact of the external air, a mere change of the temperature being intolerable. De Haen himself at length became a prey to the in- fection, and his attack commenced as thus far stated. On the fourth day, he tells us, all his symptoms were worse, his feet quite chilled, but his hands red, and agitated with convulsive motions ; he had oc- casional vomitings, and was terrified by the image of impending death. On the eighth day the pulse was convulsive, and he was continually crying out from his pains. On the ninth, delirium, and a rejection of grumous blood from the stomach. On the eleventh, perspiration and a tranquil pulse, but the voice was broken, the speech was interrupted, and the teeth grated. On the twelfth, the jaw was convulsed, there was a sardonic laugh and deafness. On the fourteenth, an icy coldness covered the whole body, accompanied with a cold sweat, but a frequent use of ablutions afforded relief. On the eighteenth, he had a vivid delirium, but fainted on being taken out of bed; which was succeeded by hunger, copious sweats, and profound sleep, with an intolerance of noise. At this time, every thing appeared new and extraordinary ; a feeling described by many sufferers as soon as the violence of the disease begins to abate, and which Dr. Pinckard has very strikingly noticed in his own case. The symptoms varied considerably from this period, and he had still many danger* to contend with. He recovered. GE. III.-SP. II.] SANGUINEOUS FUNCTION. Ill however, though very slowly, and with numerous draw-backs; for on the thirty-sixth day he had a cholera, and on the forty-eighth his skin scaled off, and he lost his nails. Towards the close of the disease, the skin was covered with a scabid or ichorous eruption, rather than petechia?; evidently from debility of the capillaries: a fact that has often occurred even in the slighter attacks of this variety of remittent in our own country, when it has occasionally broken out, as in 1765, among the troops stationed in the vicinity of Portsmouth, and is particularly noticed by Dr. Lind. In this last case it was often suspected to be the itch, to which it had a very near resemblance : and it is highly probable that in many instances it was so, and that the acarus scabiei found, in the sores, a convenient nidus for the deposit of its eggs. There are situations, however, in which the febrile miasm pro- ducing this low variety of remittent is generated by a decomposi- tion of the stagnant matter of humid marsh-lands ; such chiefly are the regions about Cape Coast, in Africa, especially when visited by the foul and smouldering harmattan, and about Gombrow, or as Sir John Chardin calls it, Bander-Abassi, on the Gulf of Persia :* in which last place the mortality is so severe between the months of April and September that the deaths are ordinarily calculated at nine out of ten of the inhabitants: and this notwithstanding that most of them retire during such period towards the mountains, and all mercantile concerns are relinquished; so that, says the Cheva- lier, " la moisson est fermee comme un parle." The diseased are commonly removed higher up the country as soon as they sicken; but, whether removed or not, they usually die in four or five days. It is possible that in both these places the danger of the disease may be augmented by the dense and stinking vapour that is perpe- tually blowing upon them during the pestilential season, the " puan- tes vapeurs de la mer," as Sir John expresses himself, " qui faient bondir le coeur la premiere fois qu'on le sent." These on the Afri- can coast are impregnated from the impenetrable mangrove swamps of the interior of" Guinea, and, on the Persian, from the saline and sulphurous exhalations of the several adjoining islands which the winds of the season pass over in their periodical sweep: and the copious disengagement of hydrogene, whose presence the intoler- able stench seems to indicate, will account in no small degree for the deficiency of living power, which so peculiarly distinguishes the malignant remittent in these quarters, in the latter region, in- deed, some such debilitating influence seems to operate habitually : for the ingenious author thus quoted adds, that " the nations carry in their complexion and constitution the proofs of their malignant atmosphere, being yellow and ghastly from the age of twenty-one, and decrepid at thirty." Bleeding in this disease can never form a part of the general practice, how necessary soever it may be in particular cases, where * Voyage du Chevalier Chardin, &c. Tom. ix. p. 511—518. 112 H^MATICA. [CL. Ilt.-OR. I. atonic congestion may oppress the head or the heart. The first requisite is pure air when it can be procured: the bowels must be •pened and kept open by active purgatives, since, from the general disturbance of the functionary balance, there is violent action in the abdominal viscera, while the vessels on the surface are entirely torpid. To restore this balance should be our next effort: and tor such purpose nothing bids fairer, or has in fact been found more successful, than the use of warm diaphoretics with opium. Oold water as a beverage, or in the form of injection, has also proved a highly refreshing tonic; frequent potations of old hock still more so; and the bark may be commenced with advantage as soon as the stomach can retain it in large doses, for here small proportions are of no avail. Ablution with cold water was also tried very gene- rally during the malignant epidemic at Breslaw, and wi(h very great advantage.* SPECIES III. EPANETUS HECTICA. f^ecttc iPcber. PULSE WEAK : STAGES OF CHILLINESS, HEAT AND SWEAT VARIOUSLY IN- TERMIXED, AND SOMETIMES SINGLE; THE COLD STAGE EXHAUSTING J THE EXACERBATION CHIEFLY IN THE EVENING. The symptoms of this species, except in its sweating stages, are far less violent, and consequently its duration is far longer than that of either of the preceding. Nothing, however, can more fully prove its complexity and irregularity, than the different characters given of it, and the different places allotted to it, by different authors. Sauvages and Sagar introduce it into the list of continued fevers. Linn^us, Crichton, and Parr, into the present division, or that of remit- ting and exacerbating fevers : Boerhaave regards it as of a mixed na- ture, a continued intermittent. " Febris hectica," says he, " est re- ferenda ad febres continuatas intermittentes.1' Vogel and Cullen degrade it into a mere symptomatic affection. " As I have never," says the latter, " observed a fever of this kind except when symp- tomatic, I could not consent to admit it into the list of idiopathic fevers, which alone ought to be enumerated." Those who have adopted Dr. Cullen:s opinion, have usually con- templated it as a mere effect of absorbed pus. Dr. Heberden * Epidemia verna quae Wratislaviam, anno 1737, affiixit. Vide Act. Nat. Cu- rios. Tom. x. GE. III.—SP. HI.] SANGUINEOUS FUNCTION. 113 seems to think it dependent upon a local cause, but that irritability in any diseased organ, which cannot be brought into a healthy state, will excite it as eflectually as pus introduced into the system. Galen, on the contrary, Mr. John Hunter, and Dr. Willan, con- tend, that hectic may be, and often is, a strictly idiopathic affection. The second of these valuable writers regards hectic fever as of two sorts symptomatic and idiopathic* The first he ascribes entirely to local irritability, and opposes the idea that it is ever produced by absorbed pus. His argument is, that if absorbed pus be capable of producing it in one instance, it ought in every in- stance : but this we know is not the case ; for we have had large buboes and even empyemas removed by absorption suddenly, and yet no hectic has taken place. He does not think that more pus is absorbed during the existence of hectic fever than when no such fever is present: but, admitting that this should be the case, he would rather ascribe the increased absorption to the hectic consti- tution, operating upon the abscess or sore, than to the abscess or sore operating upon the constitution; in which case the hectic diathesis is the cause, and the increased absorption is only the effect. So that even here, he regards the hectic as a primary or constitutional fl]Cp£)60 As a symptomatic affection, however, he refers it to a general irritability of the constitution, produced by sympathy, in conse- quence of " some incurable local disease of a vital part, or of a common part when of some magnitude ;" and which becomes in- curable from two causes; firstly, because, though the local irritation is small, the constitution is bad, and does not dispose the parts to a healing state : and secondly, because, though the constitution is o-ood, the local irritation is so considerable that it cannot muster up a sufficiency of remedial energy to subdue it; and hence, while sympathizing in the irritable action, falls a prey to its own efforts. Yet, says he, it is possible for hectic fever to be an original dis- ease of the constitution; for the constitution may fall into the same mode of action, without any local cause whatever, at least that we know of. And in this manner he accounts tor its existence as an idiopathic affection. And, in effect, nothing is more common than for hectic fever to exist in patients in which we can trace no local cause whatever : and in all such cases we must either indulge in a gratuitous hypothesis, and throw our suspicions at random upon the lungs, or the liver, or the kidneys, or thtfheart, or the mesenteric glands, or whatever other organ a few casual symptoms may suggest to the fancy; or we must at least act upon the principle of its being an idiopathic affection, even though we should refuse, in terms, to admit that it is so. . " I willingly subscribe," says Dr. Perceval of Dublin, in his ma- nuscript comment upon the authors Nosology, " to idiopathic hcc- * On Blood, Part 11. Chap. ix. Sect. i. VOL. II. 15 1 14 HtfMATlCA. [CU HI.-OR- I. tic; and have known it to last three months without any pulmonary affection, and then to break out in the lungs." There seems, indeed, great reason for admitting with Dr Stoll, a habitus phthisicorum* a hectic diathesis or temperament; the features of which are for the most part strongly marked, and are to be found in a fair skin, blue eyes, yellow hair, lax fibre, and sanguine dispo- sition. And, wherever this exists, it is probable that most of the causes of other fevers, operating upon it, will produce a hectic. And we can hence readily account for the examples brought by different authors of its being excited by diseased actions or affec- tions of the heart, stomach, mesentery, liver, pancreas, lungs, or brain ; by a suppression of various exanthems or other eruptions, or of various habitual discharges natural or morbid; by other fe- vers ; by chronic inflammations or abscesses. It is well known to be a common sequel to the measles, occasionally so to the small- pox, and in a few instances to rosalia or scarlet fever. It may hence be a result of dyspepsy; and one case is said to have been produced by eating bacon, which remained undigested in the stomach for a term of eighteen months, when it was disgorged by sickness, and the hectic symptoms disappeared.t And it is hence possible that hectic fever may occasionally spring like other remittents, from fe- brile miasm. The character of the disease is well given by Mr. John Hunter in the following words: " Hectic may be said to be a slow mode of dissolution; the general symptoms are those of a low or slow fever, attended with weakness, but more with the action of weakness than real weakness; for, upon the removal of the hectic cause, the action of strength is immediately produced, as well as every natural function, however much it was decreased before. The particular symptoms are debility ; a small, quick, and sharp pulse ; the blood forsaking the skin ; loss of appetite ; often rejection of all aliment by the sto- mach ; wasting; a great readiness to be thrown into sweats; sweat- ing spontaneously when in bed; frequently a constitutional purging." —To which he adds, " the water clear." There is, in reality, much difference of opinion upon this last point. Dr. Heberden has observed that the same irregularity which accompanies most other symptoms of the disease attends this also; that the urine is equally clear or turbid in the exacerbations and the intervals ; sometimes clear in the first and turbid in the second ; and sometimes turbid in the first and clear in the Second : while Dr. Duncan, from long and assiduous attention, asserts, that the urine is peculiarly distinguished by a natural furfuraceous separation. Such is the character it has usually exhibited in my own practice : though where authorities thus clash, it is not a symptom to be depended upon as a pathog- nomic. From the frequent approaches which the hectic makes towards a * Prselect. p. 19. t Arnold. Diss, de Hectica stomachia, 1743. GE. III.—SP. rll.] SANGUINEOUS FUNCTION. 115 perfect apyrexy, it is sometimes apt to be confounded with an in- termittent; but there is rarely any remission in which the pulse is not at least ten strokes in a minute quicker than it ought to be; and by this it is sufficiently distinguishable, as it is also by the greater irregularity of its different stages, and indeed of all its symptoms. It is owing to this last feature that, sometimes, the exacerbation commences with a chilly fit, and sometimes without; and that, when there is a chilly fit, sometimes it is immediately succeeded by heat, but sometimes by perspiration, without any intervening hot fit; while occasionally the cold fit only leads to heat, or even terminates singly without either heat or perspiration. Hence the exacerba- tions must vary in duration : but even where every stage is present and succeeds in regular order, the duration of the entire exacerba- tion is almost equally uncertain, insomuch that it is seldom that three exacerbations of equal length recur in succession. The re- missions will sometimes extend to ten or twelve days, without a single intervening pyrectic symptom: and sometimes the cold or the hot fit, or the sweating, will be renewed several limes in the same day. Yet, let the perspiration appear whenever it may, the patient is never relieved by it; but is as anxious and restless during its continuance as in the heat or chill. Dr. Heberden* tells us, that he has sometimes seen a hectic at- tack persons who seemed in tolerable health, in a sudden and vio- lent manner, like a common inflammatory fever; and, like that, in a little time bring them into imminent danger of their lives; after which it has abated, and afforded hopes of recovery. But the hopes have been deceitful, for the hectic has still been fed by some lurk- ing mischief; and, resisting the power of medicine, has gradually undermined the patient's health and destroyed him. More commonly, however, hectic fever commences slowly and insidiously, and is not suspected for some months: and the only symptoms noticeable are, lassitude upon slight exercise, loss of ap- petite, and a wasting of the flesh. But if these symptoms be con- nected with a general increase of pulse, so that the artery beats from ninety to a hundred, or a hundred and twenty strokes in a minute, there will be real ground for apprehension. This is one of many diseases in which the art of medicine has hitherto laboured in vain to strike into any direct track of cure. The real cause is commonly involved in great and impenetrable obscurity, and we can do little more than attack single symptoms as they make their appearance. Where the disease is evidently symptomatic, the case must de- pend upon curing, or, if incurable, upon removing, when this can be accomplished, the part affected. Where idiopathic, we must com- bat, as far as we are able, the irritable diathesis; and above all things endeavour to strengthen, without increasing, the action of the machine. The best sedatives as well as tonics are acids, and ■ Trans, of the College, Vol. n. Art. i. p. fi. 116 HJiMATICA. [CL. IH.-OR. I- of these the vegetable will usually be found preferable to the mine- ral, since, on account of their corrosive property, the ^Jter can only be taken in small quantities. They abate the febrile heat, diminish the restlessness, and frequently succeed in checking the night-sweats. And if, as is often the case, the patient be tormented with pains in the limbs or joints, resembling rheumatism, and pre- venting him from sleeping, we may combine the acids with opium. The bowels must be kept regular by gentle laxatives, and the neu- tral salts seem to in-wer this purpose better than most others. It will, however, be convenient to vary them occasionally, and some- times to exchange them for the senna confection, or some other aperient. Stimulants rarely answer any good purpose ; and in many instances evidently heighten and accelerate the exacerbation. The Peruvian balsam has been given advantageously with nitre ; but myrrh is a medicine of fairer promise ; and beyond these we can scarcely ever venture to proceed. The lighter bitters are certainly serviceable in many cases, and may conveniently be employed in combination with the acids : but bark, though tried in numerous instances, and with great perseve- rance, has not been found successful. Dr. Heberden, however, says, that he never saw it do any harm in the hectic fever, and his opinion is confirmed by that of Sir Edward Hulse, after having prescribed it for forty years. Yet neither of them ever obtained proofs of any beneficial result. A light and regular diet, regular hours, and gentle exercise, are coadjutants of great importance. When the disease is dependant upon some local affection, the Bath waters have often afforded relief; but in idiopathic cases they usually augment the fever, aggravate the patient's sufferings, and hasten his death. GENUS IV. ENECIA. ttoutitmrti iPrter. ONE SERIES OF INCREASE AND DECREASE ; WITH A TENDENCY TO EXACER- BATION AND REMISSION, FOR THE MOST PART APPEARING TWICE EVERY TWENTY-FOUR HOURS. We now enter upon the important genus of continued fevers, or those which run their course, not indeed without any change or relaxation whatever, as many of them were supposed to do formerly, and were distinguished by the term continentes, but with occasional and slight GE. IV.] SANGUINEOUS FUNCTION. 117 fluxes and refluxes, which bear the same proportions to the exacer- bations and remissions of the epanetus as these do to the paroxysms and intervals of the anetus or intermittent. When there are two tides or fluxes within the twenty-four hours, the one occurs in the morn- ing, and the other in the evening? The last is always the most dis- tinct ; and takes place usually between five and six o'clock, which is somewhat later than the latest of the paroxysms of genuine inter- mitting fevers; that of the quartan, which is the latest of the whole, usually occurring before five o'clock. It should also be farther ob- served that where continued fever discovers but one augmentation in the twenty-four hours, it is always that of the evening. Dr. For- dyce attempts to show that, even in a state of the firmest health, we constantly discover some tendency to a little febrile affection every evening ; this he calls the natural evening paroxysm of fever ; and to this habit he ascribes the existence of an evening increase of continued fever. The genus, thus defined and characterised, includes the three fol- lowing species :— 1. ENECIA CAUMA. INFLAMMATORY FEVER. 2. ------ TYPHUS.# TYPHOUS FEVER. 3. ------ SYNOCHUS. SYNOCHAL FEVER. Sauvages draws a line of distinction between these three from their respective duration, as well as from their more essential symptoms, affirming that the cauma terminates in a week at the farthest; the typhus, in two, though sometimes protracted to three weeks; while the synochus reaches beyond the second, and often beyond the third week. As a general rule this remark is worth keeping in mind, but the deviations from it in all the species, are too frequent to enable us to lay hold of it in assigning their specific character.

[CL. III.-' and synocha, which is that of Sauvages, Linneus, Cullen, and most writers of the present day. Of these, svnocha, for reasons stated in the comment to the Nosological Synopsis, is the worst; it has no clear or correct etymological meaning; it has been used in ditterent senses by different writers, and approaches so nearly to synochus, used as extensively by most of the same writers, as to create a per- petual confusion in the minds of young students; and the more so, as the disease before us is expressly denominated synochus by Vo- gel, whilst most writers employ this term to import a different spe- cies of fever. On all which accounts 1 have judged it right to ex- change synocha for cauma, a term already employed for the same purpose by Dr. Young, and which, derived from «*»$*, " uro, is etymologically significant of the character of the disease it desig- nates. The common English term inflammatory fever is excellent; and is in truth a direct translation of the Greek term cauma. Dr. Fordyce denominates it general inflammation: by which he clearly intimates, that this species of fever bears a near resemblance to the symptomatic fever produced by the local affections called phlegma- siae, or phlogotica, which constitute the next order of the present class, to which the term inflammations is now commonly limited; but which Dr. Fordyce would distinguish by ther^erm " local inflamma- tions." In effect, inflammatory fever and the fever of inflammations bear the same relations to each other as the idiopathic and symptomatic hectic: in both there may be a general or a local remote cause, but the influence upon the constitution will be the same, whatever be the source of excitement. It has been doubted, however, whether cauma or inflammatory fever ever exists without a local cause ; and Dr. Cullen, who does not allow that hectic fever is ever found without a local cause, distinctly affirms that he has never seen inflammatory fever existing under the same circumstances: whence Dr. Clarke, of Newcastle-upon-Tyne, who has too much generalized the sub- ject, has struck inflammatory fever entirely out of the list of dis- eases, contending that even the term inflammatory ought never to be applied to fever, excepting when fever itself only exists as a concomitant of some local affection :* while Dr. Clutterbuck, as we have already observed,! has contended that this local cause is at all times, and under every variety of fever, an inflammation of the brain. How far either hectic or inflammatory fever may, under particular circumstances of humana or atmospherical constitutions, occasionally originate from marsh or contagious miasm, it is difficult to determine; but as Dr. Cullen was peculiarly desirous of reducing all fevers to these two sources, and as, to say the least, they are not obvious sources of either of the diseases in question, his mind appears to have received some bias from this fact, in rejecting them from the list of idiopathic fevers. And as it has already been shown * Observations on Fevers, &c. 8vo. London 1779. + Vol. h. p. 41. «E. IV.-SP. I.] SANGUINEOUS FUNCTION. 119 that this decision has laid a foundation for much Of that " tug of war" in which many distinguished members of the profession have of late years been engaged, respecting the nature and treatment of particular species of fever, it is highly probable, also, that several of the more recent hypotheses concerning its proximate cause have originated from the same spring. Inflammatory fever, as it has often occurred in the author's own practice, and in that of others who have described it, usually com- mences with the Symptoms of an acute ephemera, and may in fact be contemplated as the same disease running on from four or five to about eleven days without intermission, or a renewal of the cold fit. It commences with a sense of languor and inaptitude for exer- tion, with a disrelish for food, which continues for a day or perhaps two. There is then chilliness and soreness over the surface, with nausea and head-ache, succeeded in the evening by a great increase of heat, and at night by perspiration. The bowels are usually costive, the urine high coloured, and the pulse quick and hard. With Dr. Fordyce the grand pathognomic symptom of cauma is hardness of the pulse. This accompanies it from first to last in its simplest and in its severest state. When the disease is mild, it is hard alone ; when more violent, it is at the same time full, strong, and frequent. The obstructed pulse is often confounded with the hard, and it is not easy to distinguish them without considerable practice. There is a rigidity of resistance to the finger in each, but of a different kind. In the hard pulse, it is much firmer and tenser; and is supposed by Dr. Fordyce to result from such an in- crease of arterial contraction as to over-balance its correspondent dilatation. It indicates, in his opinion, a very high degree of living power, and is peculiarly characterized by a tardy coagulation of the blood when drawn freely into an hemispheric bason, in consequence of which the red particles have time to subside, and leave the sur- face colourless or with a buffy appearance. In the obstructed pulse, on the contrary, the blood coagulates at once ; and, the red particles not having time to separate, the surface is of the same hue as the cake below. The disease sometimes terminates abruptly and with a critical sweat, or some other evacuation on the fourth or fifth day : but more usually increases in violence, though with occasional declina- tions, for a week longer; during which time, the pulse rises to a hundred or a hundred and ten strokes in a minute, but continues re- gular; the nausea subsides, and the patient will take and retain whatever is offered to him of simple nutriment or medicina : the thirst is less violent, but the tongue is deeply furred, and the lips are parched. The disease is not often dangerous; and about the eleventh day gradually subsides, or yields to some critical discharge, which is usually that of a free and alleviating perspiration The pulse soon sinks to eighty, and the chief symptom is weakness. During the course of the fever, every organ suffers from its mor- • J20 hjematica. [cl. iil-or. i. bid and increasing impetus ; but they do not all suffer alike : for in some parts there is, occasionally, a greater spasticity or tetanic re- sistance in the blood-vessels, to "the flow o' the circulating fluid than in others, whence that acute pain which is often complained of in the head or the side ; in the latter case, sometimes amounting to pleuralgia. And, not unfrequently, the vessels of one part will give way more readily than those of another, and there will be a sense of heaviness and oppression in the head, the heart, or the lungs; as though some effusion had taken place, which is perhaps actually the case in some instances. If the head be much affected, delirium is a frequent result, with raving and violence, rather than the low muttering incoherence of asthenic fevers. From the history already given of the malignant Causus, or ar- dent malignant remittent, it appears probable that inflammatory fever may sometimes be produced from febrile miasm, though it is commonly derived from other sources. Of these the stimulus of violent passions is, perhaps, one of the most common; and especial- ly upon a vigorous and plethoric habit, which is the usual tempera- ment in which inflammatory fever makes its appearance. Undue muscular exercise, heating foods, or excesses of any kind in the same habit, are also frequent causes; while another may be found in the suppression of any accustomed discharge, as that of men- struation, epistaxis, or periodical blood-letting. Suddenly suppres- sed perspiration is, in like manner, a frequent, perhaps the most frequent cause of any; especially when the body is very hot, and the change is effected by exposure to a temperature of great cold, applied externally or internally, as that of a current of cold air, a large draught of cold water, or plunging into a river. Some writers, as Sennert and Crichton, have supposed inflam- matory fever to be occasionally produced by an absorption of bile into the blood-vessels under the excitement of a tropical sun, or of a torrid summer in milder regions; and they suppose that the bile is, in this case, possessed of a more than ordinary degree of acri- mony, and that the symptoms are varied by a more pungent heat and more intolerable thirst, with a more scanty secretion of urine, preternaturally acrid and high-coloured. That bile of this description is often forced back into the system under the circumstances here supposed, is unquestionable ; as it is also that inflammatory fever is a frequent accompaniment of this morbid change. But notwithstanding the above authorities, such fever seems less attributable to the reflux of bile into the blood than to the insolation or solar excitement; which, by unduly stimu- lating the liver, has been the cause of an overflow of the bilious secretion How far a more irritant or exalted acrimony may be communicated to bile thus operated upon, or what may be its effect upon the system, admitting it to take place, it is difficult to deter- mine ; but there is much reason to doubt whether genuine bile in the sanguiferous system is ever a cause of fever, or stimulates the heart or arteries to increased action, for if this were the case, GE. IT.-SP. I.] SANGUINEOUS FUNCTION. 121 jaundice would always be accompanied with inflammatory fever. Instead of which, however, we find it accompanied with atony in- stead of entony, or diminished instead of increased power. Sauvages gives a case in which inflammatory fever was produced by a mechanical irritation of the meninges of the brain, by a lodg- ment of vermicles in the frontal sinus, of wh ch seventy-two were discharged during a fit of vomiting and sneezing, from which time the patient began to recover. These vermicles were most probably the larves of some species of the oestrus or gad-fly, which had crept up into the frontal sinus, after being hatched in the nostrils in which the parent insect had deposited her minute eggs. This is a very common affection in grazing quadrupeds, and especially in sheep, which are often pecu- liarly tormented, and sometimes driven almost mad by the violence of the irritation. Stoll gives a case in which the brain, on examination after death, was found deluged with serum diluvium serosum * But such an ap- pearance is rather to be regarded as an effect than a cause of the disease ; as an instance of cephalitis profunda, in consequence of the brain having suffered more than any other organ from the inflam- matory impetus. Hence the following varieties are noticeable under the present species: x Plethoricum.

As an inflammatory diathesis constitutes the essence of this fever, the cure must depend altogether upon a reduction of the vascular, and especially of the arterial entony: always bearing in mind the possibility that the disease may suddenly lose its inflammatory char- acter, and rapidly pass into that of a typhus. Regulated by this view, we should generally commence with bleeding and cooling purgatives. There are a few cases, indeed, in which bleeding may be dispensed with, as when the habit is by no means plethoric, and the pulse obstructed rather than hard; but these are cases that rare- ly occur. Diaphoretics, or relaxants as they are denominated bv * Mat. Med. in. p. 294. vor,. n. 16 122 HiEMATICA.

And it may not be amiss to observe here, that the acetate of ammonia is sometimes prepared in the form oi crystals, and sits more easily on the stomach in this than in any other shape. When given as a liquid, it is of importance that the solution should retain the carbonic acid gas of ammonia as largely as possible; and for this purpose the union should take place in a strong close vessel. According to Bergman, nearly half the weight of ammonia depends upon the quantity of this gas which it con- tains ; so that in a pint of the solution of the acetate of ammonia, comprising four drachms of the latter, there will be extricated, if made in the manner here recommended, little less than a hundred and sixty cubic inches of air. As the stomach is for the most part but little affected, emetics, if used at all, can only be employed for the purpose of determining to the surface; but as we can do this by the antimonial and other diaphoretics just referred to, as also by diluent drinks, it is hardly worth while to irritate the stomach in order to accomplish the same purpose. Perfect rest of body and mind, a reclined position, and a light liquid diet, destitute of all stimulants, are also indispensable toward recovery. The air should by all means be kept pure, by being constantly renewed, though without a sensible current, the temperature cool, and the clothing light and as often changed as may be necessary to maintain cleanliness. After all, however, it is not often that examples of pure inflam- matory fever are to be met with in the present day; and it is con- tended by very high authorities, and seems to be established by the medical records of earlier times compared with those of our own, that it is a disease far less common now than it was formerly; and and that it is seldom, to adopt the words of Mr. J. Hunter, " that phy- sicians are obliged to have recourse to the lancet, at least to that excess which is described by authors in former times. They are, now, more obliged," continues the same writer, " to have recourse to cordials than evacuations; and, indeed, the diseases called the putrid fever and putrid sore throat are but of late date. I remem- ber when the last was called Fothergill's sore throat, because he first published upon it, and altered the mode of practice. I remem- ber when practitioners uniformly bled in putrid fevers; but signs of debility and want of success made them alter their practice. Whether the same difference takes place in inflammation, I do not know, but I suspect that it does in some degree; for I am inclined to believe that fever and inflammation are very nearly allied and that we have much less occasion for evacuations in inflammation than there were formerly ; the lancet, therefore, in inflammation, and also purgatives, are much more laid aside."* * On Blood, &c. Fart 11. p. 227. GE. IV.-SP. I.] SANGUINEOUS FUNCTION. 123 It is not easy to account for this change in the national tempera- ment. It is common, indeed, to ascribe it to an alteration in our mode of life, which is asserted to be much fuller than that of our forefathers. " We may be said," says Mr. Hunter, " to live above par. At the full stretch of living, therefore, when disease attacks ns, our powers cannot be excited further, and we sink so as to re- quire being supported and kept up to that mode of life to which we have been accustomed." If this be a correct view of the times in Mr. Hunter's day, they have greatly altered and improved within less than half a century: for there has never been a period, since wines and fermented liquors have been introduced among us, so temperate and sober as the present. Drunkenness, which was formerly common in our streets, is now rarely met with ; suppers are almost entirely relinquished ; and instead of its being disgraceful, as was the case in ' the olden time,' for the master of the house to let his guests leave him either sad or sober, nothing is now so disgraceful as intoxication. It is true we are got back again to a very free use of the lancet in many instances -/which would seem to show that we had completed a revolution in our general temperament, as well as our general temperance ; but it is not a little singular, that while the lancet is still used with comparative caution in inflammatory fever, it is chiefly employed and often unsparingly in typhus, or putrid fever. And hence, there is more reason, I fear, for suspecting a revolution in the professional fashion than in national temperament; and that the bold and the timid plans have been alternately introduced, and alternately dropped, not so much from any radical change in the constitution, as from their being found to fail, because employed as popular means, or under the influence of some favourite hypothesis on all occasions, without a due degree of clinical discrimination, or attention to the habits or symptoms of individuals at their bed-side. SPECIES II, TYPHUS. Egjinus iFetoer. ,mSE SMALL, WEAK, AND UNEQUAL ; USUALLY FREQUENT ; HEAT NEARLY NATURAL ; GREAT SENSORIAL DEBILITY, AND DISTURBANCE OF THE MENTAL POWERS. The term is derived from Hippocrates, who uses it, however, in a sense not exactly parallel with its application in modern times. It is, nevertheless, admirably expressive of the general nature ot the fever to which it was applied at first5 and which it designates at 124 HiEMATICA. [CL. II1.-OR. I. present; which burns, not with open violence as the cauma, but with a sort of concealed and smothered flame ;—for the Greek term ri*« signifies " to smoulder," or " to burn and smoke without vent Any of the ordinary causes of fever maybe a cause of typhus tor the typhoid form is often dependant upon the character of the constitution into which it is received, as evincing a great dehc.cncy of sensorial power: and hence cold, mental agitation, exces.ot muscular labour, and even intemperance, which m a high entonic habit might generate synocha or inflammatory fever, will often in a debilitated constitution, and especially when the debility depends primarily upon the state of the nervous system, and the nervous fluid is recruited with difficulty, give a typhous complexion to the disease from the first. . . , But though all the causes of fever may in this way give rise to typhus, its common cause, as we had occasion to notice when treating of the remote causes of fever,* is febrile mia^m, issuing from the decomposition of human effluvium, under the influence ot the ordinary auxiliaries of a close and stagnant atmosphere ; still farther corrupted by a load of foreign exhalations from dirt or hlth of any kind, and of that degree of warmth and moisture which must always exist where society exists, and especially where it exists in too crowded a state. Under these general circumstances a very low degree of warmth and moisture is sufficient, though there must be some proportion of both. And provided there be an adequacy of warmth, the lower the temperature, the more certainly an individual becomes affected; not from a more abundant generation of febrile miasm, or from its being more volatile—for, on the contrary, it is here perhaps less abundant and even less volatile—but from the more depressed state of the living power, and the less resistance it is capable of offering to any morbid influence whatever. I have just remarked, that under a depressed state of the living power, whatever be its cause, whether a want of cheerful warmth, cheerful passions, cheerful food, or cheerful and regular habits, typhus is often more likely to take place than any other species of fever. But when febrile miasm, produced by a decomposition of effluvium from the living body, exists in co-operation with these, it is almost impossible for an individual to escape ; as the miasm thus generated has a specific power—a power beyond all other febrile causes whatever—of lowering still farther the vital energy as soon as it is received into the system, and thus of confirming the previous tendency to this peculiar type. All this indeed has been observed already, though it is necessary to revert to it on the present occasion : it has also been farther observed, that when a typhus has in this or any other manner once arisen, the effluvium from the living body during its action is loaded with miasm of the same kind, completely elaborated as it passes off, and standing in no need of the decomposition of the effluvium for its * * Vol. H. CI. in. Ord. i. p. 49. GE. IV.-SP. II.] SANGUINEOUS FUNCTION. 125 formation. In many cases, indeed, all the secretions are alike contaminated ; and, hence, febrile miasm is often absorbed, in dis- section, by an accidental wound on the hand, and excites its specific influence on the body of the anatomist. Hence, typhus becomes infectious ; but as the miasm it generates, though more suppressive or exhaustive of sensorial energ}', is less volatile than that of marsh-lands or dead organized matter, its infec- tious power is confined to a much more limited atmosphere than that of fevers originating from this latter source. And, on this account, fevers originating in jails, or other confined and crowded scenes, are less extensively communicable than the yellow fever, or that of hot climates and exhaling swamps. It may be also necessary to recal the reader's recollection to another remark that has also formerly been made, that in a pure atmosphere, the miasmic materials, from whatever source derived, become dissolved or decomposed ; but slowly and with great diffi- culty, perhaps not at all, in a vitiated atmosphere already saturated with foreign corpuscles.* In a state thus crowded, moreover, they less readily disperse or ascend beyond their proper periphery of action ; and where they are less volatile, as when issuing from human effluvium, they perhaps adhere by a peculiar tenacity to bodies more ponderous than themselves, and thus loiter for a still longer period within the stratum of human intercourse. And hence the fouler as well as the more stagnant the atmosphere, the more general, and, from the former cause, the more malignant the disease : for as nothing is so contributory to the preservation of sound health as pure air, so nothing tends so much as foul air to prolong or aggra- vate diseases of every kind. And hence, again, we have an obvious and sufficient reason why typhus should become more severe in proportion as it spreads and impregnates a given space with its specific miasm and accompanying colluvies. To what extent febrile miasm, issuing from the source before us, may spread in a free influx of pure air without becoming dissolved, or, in other words, so as to retain its contagious power, has never been very accurately ascertained. We know, however, that, its range is very circumscribed, and reaches to but a very small distance from the patient, or the nidus of foul clothes or utensils in which it may be lodged ; and never infects a person in an adjoining street, or house, or room in the same house ; nor even, as Dr. Haygarth has observed, in the patients own chamber, if large, airy, and kept clean. It is also of great importance to know that typhous miasm, like the specific miasms of exanthems, does not render clean clothes of any kind contagious; or, in other words, does not adhere to or harbour in them. VVhen, however, they are not clean, they may unquestionably be rendered contagious ; and, hence, it is probable that the animal filth with which they are impregnated, while it is Vol. n. CI. I. Ord. I. Sect. 9. p. 53. 126 HJEMATICA. [CL. IH.-OR. I. a source of additional matter, becomes a fomes of that already formed, and separated from the patient's body. A susceptibility, however, to diseases of every kind vanes very considerably in different individuals; and hence we find that many persons upon an equal exposure to typhous contagion with others, receive it far less readily, and in some cases seem to be almost favoured with a natural immunity. As we have already remarked that a particular state of body gives a peculiar tendency both to generate and receive typhus, we can easily conceive that ™ere the body is in an opposite state it must be much less susceptible of its influence; and we are thus put in possession of a general cause of escape. But there seems to be something beyond this, dependant indeed, not upon the incidents of more vigorous health or higher animal spirils, but upon the nature of the idiosyncrasy itself. Dr. Haygarth has endeavoured to determine, from very ingenious and plausible data, the average proportion of those who in this manner remain exempt from contagion, while spreading on every side around them. And he limits the immunity to one in twenty- three : for he tells us, that when one hundred and eighty-eight men, women, and children, were exposed fully to the typhous contagion for days and nights together, in small, close, and dirty rooms, all of them, except eight, were infected with this fever.* And he has farther endeavoured to show, that the miasmic poison, when received into the body, continues in a latent state for seven days, from the time of exposure to the contagion, before the fever commences, and may continue in the same state for seventy-two days, beyond which we haye no instance of its producing any effect. And this deduction is in pretty close unison with the experience of Dr. Bancroft,! who in ninety-nine cases of orderlies and nurses that attended the English army on its arrival at Plymouth from Corunna in 1809, observed that they were rarely attacked with fever earlier than the thirteenth and in no instance later than the sixty-eighth day. Man, however, is so much the creature of habit, that his constitu- tion is in a thousand instances brought by degrees to endure poisons of the most fatal power. This we see daily in the use of opium and ardent spirits ; and we shall in due time have to notice something of the same kind, even in plague. This adaptation of the constitu- tion, however, to the circumstances by which it is surrounded, is in nothing more conspicuous than in the fever before us. Not, in- deed, in all persons—for all do not possess the same pliability of con- stitution—but in those who are endowed with it. And, hence, one reason why nurses and perhaps hospital-surgeons escape so often without injury ; and especially why prisoners brought into a court for trial remain themselves occasionally in perfect health, while their clothes are so impregnated with the contagious miasm as to * Letter to Dr. Percival, p. 31. t Essay on Yellow and Typhus Fevers, p. 515. »E. IV.-SP. II.] SANGUINEOUS FUNCTION. 127 infect a whole court, and communicate the disease to the judge or others who are at the greatest distance from them. There Ire other persons again, as Sir George Pringle has well observed, whose constitutions forming a middle line between those who readily receive, and who powerfully resist the contagious aura, are affected only in a modified degree. They bend to the assault, but are not cut down by it. They become feeble and irritable ; the sleep is disturbed; the tongue white in the morning; the appetite impaired; the smallest exertion fatigues them, and accelerates the pulse ; and in this state they remain for weeks together, and at length recover without any formal attack of fever. We have seen that the same influence of habit exists under yel- low fever; during which the natives of those climates, where its remote causes are in almost perpetual operation, suffer far less when it attacks them, and are far less susceptible of its attack. But though febrile miasm issuing from a decomposition of human effluvium has a peculiar tendency to generate typhus, we have seen that the same miasm issuing from a marsh effluvium or a decompo- sition of dead organized matter, under a peculiar state of modifi- cation, has produced remittents with a typhus character, and some- times specific typhus itself* And, as in this case, the miasm is apt to spread more widely, typhus has by many writers been said to be occasionally epidemic. When, however, the disease issues from this source, it is far more generally in temperatures too low than too high and heated; since, as already observed, cold, and especially cold and moisture, have a peculiar tendency to depress the living power: and hence this disease is said to be almost stationary at Carls- crone, or at least to have lingered there for four or five years on some occasions.! Typhus, therefore, originating from different causes, and all these causes modified in their action by collateral circumstances, may readi- ly be supposed to be accompanied with very different symptoms, and to appear under very different degrees of severity. The chief varieties, however, are the two following:— x Mitior, Nervous fever. C Gravior. Putrid fever. The first variety, or mild typhus, was called by Dr. II xmhixm febris lenta nervosa, and has hence been commonly distinguished by the name of low or slow nervous fever, from the great languor and de- jection of mental or sensorial power with which it is always accom- panied, and on this account it has sometimes been denominated the hysterical fever.\ It is particularly characterized by slight shiver- ings; heavy vertiginous head-ache; oppression at the pracor- * Epanetus malignus asthenicus, Vol. ii. p. ill. t Foxe Neuen Schwed.

I. dia ; nausea ; sighing ; despondency ; coma, or quiet delirium ; whey-like urine. When the disease appears sporadically, it is usuall/under this form. There is nothing alarming to the patient's friends on its accession. The first symptoms are slight, the tongue exhibits tittle change, and the pulse is only a little quickened, and somewhat smal- ler than usual: at the same time, however, there is great anxiety and depression of mind ; so that the symptoms do not much differ from a mild and comparatively insignificant fever of any kind operating upon a nervous temperament. But as the disease advances, all the symptoms of sensorial debility become severer ; the skin, which has hitherto been mostly dry, will about the third day be covered with profuse, clammy, debilitating sweats, while the heat is still incon- siderable, and the countenance pale and s«nk. The sweat is often offensive to the smell, frequently acid, and sometimes, according to Stoll, as sour as the sharpest vinegar.* About the tenth day the weakness greatly increases; all the limbs tremble ; and the tremors soon become convulsive, with a despondency and alienation of mind, at first observable only in the night, but soon continuing with little intermission: the delirium is of the mild or quiet sort, and rarely amounts to phrenzy. The disease often runs on to the twenty-first day, and occasionally to a much longer period. It is seldom marked by that sudden change which can be called a crisis; but gradually becomes more aggravat- ed in its symptoms till it reaches a fatal termination; or slowly advan- ces to convalescence, by evincing a disposition to natural sleep; more steadiness and firmness of pulse ; a more favourable counte- nance ; a tongue more florid at the edges; a firmer and more collect- ed mind; and a returning desire for food, often indeed capricious, but without nausea or sickness. In an anomalous and very singular case, related by Dr. Satterley,t the desire for food, which at first was greatly loathed in whatever form offered, reappeared about the fifth day with an enormous crav- ing which it was impossible to satisfy. Animal food was preferred, but food of any kind was swallowed voraciously; and when food was not allowed, various indigestible substances were devoured in its stead. This desire returned with every returning ingravescence of the fever, which adhered to no regular period ; and it continued as long as the ingravescence lasted, which was usually ten or twelve hours. The disease extended with numerous variations to upwards of thirty days, when the fever unequivocally subsided, and the pa- tient gradually recovered. Of the treatment we shall speak, after considering it in its severer forms. The heavier, severer, or putrid typhus chiefly differs from the mild in the violence and rapidity of its inarch, and the marked and * Rat. Med. m. p. 79. t Med. Trans. Vol. v. Art. xxn. Gtj. ir.-SP.

While the mild therefore commences insidiously With only slight shiverings, the heat scarcely above the natural temperature, and the pulse small, and only a little quickened, the heavy typhus opens with sensible and alternating rigor and heat, succeeded by little or no perspira- tion ; the pulse is tense and hard, usually quick but fluttering; pain over the forehead and crown; urine alternating from limpid to tur- bid ; delirium succeeded by stupor, and early signs of putrescency. From the last feature, the disease has derived its common name of putrid fever ; as it possesses the additional names of jail, camp, and hospital fever, from its appearing so frequently in these situa- tions, ju During the first twenty-four hours the alternate heat and cold are considerable ; the fever increases every evening, and in the second week the delirium usually commences ; the stupor following hve, six, or seven days afterwards. From the first there is a violent head-ache and vomiting; the pain over the forehead shoots through the eyes to the bottom of the orbits ; the eyes themselves are lull, heavy, and slightly inflamed ; the countenance is bloated ; the tem- poral arteries throb, while the pulse at the wrist is small; the ears tingle ; and the mind, antecedently to the delirium, is fearfully de- IGCtCcl. The balance of the sanguiferous system is generally much distur- bed, from a greater degree of sensorial debility in some organs than in others; and hence, the blood is determined irregularly, and ac- cumulation, affusion, and inflammation are frequent effects. 1 hese show themselves chiefly in the head, the lungs, and the liver; but there is no organ in which they may not occur ; and they never can ©ccur without danger. If no critical change take place about the fourteenth day, leading distinctly to an amended state, the symptoms of putridity increase both in number and degree ; there is great faintness ; difficulty of respiration, intermixed with deep sobs ; the breath is hot and offensive; acute pains in the loins and limbs; a heat upon the skin biting and pungent, rather than burning, leaving a smarting sensation on the fingers for several minutes after touch- ing it, and which from this very peculiar effect has been called calor mordicans. The tongue, whitish at first, is now dry, dark, livid, black, or of a pomegranate colour. The lips are furred with a black tenacious sordes; the urine becomes brown or blackish wi h a most offensive smell; a blackish or bilious matter is occasionally thrown up from the stomach; the skin is more or less discoloured with flea-bite-shaped or broad purple spots; the stools are blackish and highly fetid. Cold, clammy, colliquative sweats and convul- sions, sometimes accompanied with hemorrhage from one or more organs, soon afterwards usher in death; the period of which is ex tamely uncertain, and ranges from the fifth to the eighteenth day, according to the malignity of the attack, the strength of the patient or other contingent circumstances.

But if this be the ground upon which it acts, few practitioners would be disposed to recommend it, while if it be not, we have no other ground that will furnish us with a SaBuUt0h7vralre\ady°nobserved that the theory is of little impor- tance provided the practice has justified itself by the event How then stands the sum of general opinion upon this subject, ine practice is, by no means, new, though ordinarily supposed to be ot recent origin: for it has alternately lived and died away, been re- vived and again sunk into disrepute, for considerably upwards ot three centuries ; and its advocates have, in various times, been as numerous and as confident, and have maintained as warm a contest, as we are called upon to witness at present: ot which any one may convince himself who will turn to the books referred to in proof ol this assertion at the foot of the page ;* of which the first three were published in the sixteenth century, the ensuing two in the seven- teenth, and the last two in the middle of the eighteenth. The work of Professor De Biichner, of Halle, was strenuously opposed in his recommendation of venesection, at Paris by Chambon de Montaux, and at Rome by Sinibaldi. Yet, as in the present day, the suppor- ters of the depleting system had also not a few controversies amongst themselves, though they were not precisely of the same description as those in our own time ; the chief point of dispute being the part of the body from which blood could be drawn with most advantage; some practitioners performing on the arm, and others on the leg or foot; a point, however, that gradually lost its importance, as the doctrine of the circulation of the blood became more generally adopted and understood. Judging, therefore, of the expediency of blood-letting from the history of the practice before us, when enforced as a general rule in typhus, the sum of medical opinion upon a trial of three cen- .tiiries is against it. The practice has occasionally started into popularity, but it has never been able to establish itself. In the peculiar states of the disease I have already adverted to, it may be useful, and ought not indeed to be neglected : but every case must speak for itself, and the rule must not be confounded with the ex- ceptions. And such, in effect, was the opinion of Dr. Gilchrist, as expressed in his treatise on Nervous Fevers, published seventy years ago, in which he tells us, that at that period " the ordinary * Bernauli Caxancs, De Ratione mittendi sanguinem in Febribus putridis, Bar- celon. 1592.

The passage is weil worthy of attention, as containing the tree opinion of an able, candid, and distinguished writer upon an extensive ex- amination of the subject in his own day: and an opinion, too, which is very considerably in accordance with the opinion and practice of Sir John Pringle and Dr. Huxham. It should never be forgotten, however, that the expediency of bleeding must depend, not only on the diathesis of the individual, but very considerably on the state of the atmosphere. This remark I wish to enforce very strongly on the attention of practitioners, as it is derived from experience, and is of more importance than it may at first perhaps appear to be. As inflammatory fever has, sometimes, a tendency from peculiarity of constitution or accidental circumstances to run rapidly into typhus; typhus, in like manner, occasionally meets with incidents that suddenly reverse its charac- ter and incline it to an inflammatory type. A very stimulant plan of treatment has sometimes done this; but far more frequently a sudden change in the atmosphere, from hot, hazy, and relaxing weather, with scarcely a breath of air stirring abroad, to a dry, cool, and refreshing east or north-east breeze : and I have often found a like tonic effect produced upon a patient labouring under typhus in a low, damp, filthy, and suffocating lodging, upon his being removed into a large, cool, pure, and well-ventilated chamber, such as is now generally found in our fever institutions. In this case, bleeding, which I had not dared to risk, notwithstanding some symptoms of oppression, before the removal, has been practicable without any risk afterward^, and has laid the foundation of a speedy and effec- tual cure ; and I am inclined to think that some part of the clash of opinion, which prevails upon this subject in the present day, pro- ceeds from a want of due attention to the different states in which different or even the same patients are placed by this difference in the purity and temperature of the surrounding atmosphere ; and that many hospital-physicians, who are the warmest advocates for san- guineous depletion in their own fresh, cool, airy wards, would hesi- tate upon its expediency if they were to attend their patients through- out in their own close, heated, and miserable habitations. It is only a few months ago that i was consulted by a very re- * Edin. Med. Essays, Vol. iv. p. 281. VOL. II. 18 138 HiEMATICA. [CL. III.-OR. I. spectable practitioner in Hertfordshire, upon a plan of treating ty- phus, which was then raging with great violence among the poor of the town in which he resided. He had been a surgeon in the naval service of the East India Company : and having witnessed the benefit of early and copious bleeding in the yellow fever, had very generally followed it up in the contagion before him, and, as he frankly confessed to me, with a decidedly unfortunate result. My advice was. before he thought of the lancet to take care of the ven- tilation ; and then to subject it to the restrictions here laid down, and to let every case be its own interpreter. And a letter received from him a few weeks afterwards expresses his obligations for the advice, and the success that had resulted from it. Upon this subject there is a passage in Dr. Hennen's Military Surgery so strikingly in point that 1 cannot avoid quoting it. After thelfamous battle of Vittoria, in July 1813, the sick and wounded of the British and Portuguese army were chiefly removed to a tem- porary hospital established at Bilboa; where typhous miasm having soon been produced by its ordinary causes, of a foul and stagnant atmosphere, crowded wards, and depressed spirits, the sick were soon affected, and whatever was the nature of the individual con- stitution, the wounds of all of them ran rapidly into a typhous gan- grene ; " exhibiting," says Dr. Hennen, " one of the most subtile and destructive poisons that ever infested an hospital, attacking equally the most robust and the most debilitated, and, if unchecked by medical aid, proceeding invariably to a fatal termination."* The atmosphere was, at this time, sultry and relaxing ; and greatly contributed to the general debility. " I need scarcely say," con- tinues Dr. HennenJ " that a remedy so strongly recommended as venesection had early occupied our attention : but previous to the month of October the obviously typhoid type of the disease made us extremely averse from employing it. At that period, however, a change in the weather from sultry to cold, and even frost (at night) took place, marked by a corresponding change in the ther- mometer, which, at its medium range, was 20° lower than in the preceding month.—But what more than all convinced us of the change of tvpe, and pressed on our consideration the propriety of blood-letting, was, that the spontaneous hemorrhages which former- ly sunk the patients strength were now accompanied with obvious relief." And he proceeds to state that from this time the practice of venesection, on the appearance of inflammatory symptoms in a wound or newly-healed stump, became general, and was the only remedy had recourse to whether as a cure or a preventive. Of such importance is it for us to be guided by particular and general circumstances in the treatment, not merely of typhus, but of all diseases whatever: to let the rule have its exceptions, but not to mistake the exceptions for the rule. " The art of physic," * Principles of Military Surgery, p. 19. + Id. p. 223. GE. IV.—SP. II.] SANGUINEOUS FUNCTION. 139 says Sir George Baker, " rarely admits of any perpetual precepts; and the best medicine may do harm if not adapted to the patient as well as to the disease."* There is another remedy of very extensive use in the cure of typhus, far less disputable, and which is founded altogether upon the indication of equalizing, supporting, and restoring the sensorial power: and that is, the free application of cold water, and especial- ly externally. This valuable medicament has been employed in some form or other almost immemorially. Hippocrates recommends it in malig- nant fevers generally in the form of epithems, or napkins wetted with cold water and applied repeatedly to the head or any other viscus as the cloths became warm.t Among the later Greeks, how- ever, it does not appear to have been in very general use ; and though it is highly prized by Celsus, in various debilities, and es- pecially sensorial debility affecting the head, and combined with fever, in which, says he, " existat validissime repente aqua frigida infusa,"| yet it does not seem to have constituted a fixed, or even a frequent practice in his day. In our own country it was success- fully employed by Dr. Willis, in various fevers, and especially those accompanied with delirium ; and was hence strongly recom- mended by Sir J Floyer and Dr. Baynard: and was used on the continent, not merely in the form of epithems,§ and affusions, but occasionally in that of immersion, or cold bathing in a river adjoin- ing the patient.|| On the continent, indeed, it seems to have been employed at a much earlier period than in our own country, as we learn from Milot's Dissertation, " Ergo febris frigidis et humidis expugnenda," printed at Paris in 1594; and Hernault's, on the same subject, " Ergo propria febrium medela refrigeratio," printed in the same place in 1630. It was also used internally as well as externally, both in our own country as well as on the continent, especially in Spain and Naples, as is obvious from Dr. Hancock's Febrifugum magnum,1T and Dr. Cyrillo's paper on the subject in the Philosophi- cal Transactions. Even snow, or snow-water, under the name of aqua nivata, or aqua nive refrigerata, was also occasionally employ- ed ;** and, in the ardent fever, recommended by Paullini both ex- ternally and internally tt And to prove how torpid to common im- * Med.

J._r»ene- vuti, in another part of the Transactions just referred to. un ine ninth and tenth day from the incursion of a malignant fever, ne was thought to be in great danger. On the eleventh, he "pressed a wish to go to sleep, and desired the attendants to withdraw. On their return, he was found to have left his bed; and three days afterwards was discovered in a hut in a vineyard, about two miles from the house, having but just recovered his senses, and as much wondering how he came there as those who had traced him out. It appeared, on farther inquiry, that he had descended from his chamber by the window, in his shirt alone, and in a great perspira- tion ; had walked all the way in the snow with which the ground was then covered, and had swallowed a large quantity of it to quench his thirst. Yet neither the cold air nor cold beverage af- fected him otherwise than beneficially. He continued well from this time.* The use of cold water, however, as well external as internal, ap- pears on many occasions to have been employed with too little caution, and hence one reason of its falling into frequent disrepute. Even as early as 1581, Masini thought it right to guard the pro- fession against its abuse, by a work expressly devoted to this sub- ject ;t and numerous others occurred in succession through the ensuing century. In our own day, Dr. Wright of Jamaica is, perhaps, the first phy- sician who revived the practice ; but it is chiefly to the judgment and experience, the writings and recommendation of Dr. Currie of Liverpool, that cold water as an external application is indebted for the high and deserved degree of popularity it again possesses, and especially in typhus. It is now equally used in the form of sponging, ablution, and af- fusion, the last of which is the xxrxxXvns of the Greek writers, though the term occasionally also imported immersion. All these are of essential use ; yet the most sudden and decisive benefit has been observed to result from affusion ; for which purpose the patient is to be supported on a stool in a low wide tub, and to have a small bucket of water, containing about two gallons, poured brisk- ly on his head, and repeated four or five times in the course of the twenty-four hours, when the surface of the body is hot and without perspiration. In many cases this plan alone has proved successful, and the fever has been cut short in a day or two from its com- mencement. But the method is two violent and exhausting to be employed after the first three or four days of attack ; beyond which Planchon, Journ. de Med. Tom. xxx. p. 127. Lamarque, id. Tom. txvi. 460.

J41 it will generally be most useful to restrain ourselves to epithems about or all over the head, the hair being removed for this pur- pose, or sponging the body generally : and if the sensorial debility be extreme, we should prefer tepid to cold water, or mix with the cold water a little brandy or other spirit. When this method suc- ceeds, the usual salutary effects are, a considerable diminution in the number of the pulse ; diminution of heat and head-ache ; natural sleep, and a breathing perspiration. It does not appear to me that the principle has yet been fully ex- plained by which the external application of cold water becomes thus unequivocally beneficial. This is generally referred to its tonic power in exciting a reaction as the result of its chill. But though affusion often produces not only a chill, but even horripi- lation, sponging the body with tepid or even with cold water pro- duces no chill of any kind ; and there are many cases of extreme debility in which, if a chill were to take place, it would be most mischievous, and certainly would not be succeeded by any heat or reaction whatever. Independently of which, the refreshment takes place too speedily for such an effect, and is of a different and more tranquillizing kind than the excitement which follows upon the chill of cold bathing in a state of health. And I cannot, therefore, but think it probable that much of the good effects of the external ap- plication of cold water in typhus and other complaints depends upon a decomposition of the water; though whether by an absorp- tion of caloric or of oxygene, alone or in conjunction with any other principle hereby set free, is by no means easy to determine. There is yet much to be learnt upon the cause of that beneficial excitement which the decomposition of water exhibits in various bodies, both organic and inorganic, with which it comes in contact. We see plants instantly revived, the fire in the blacksmith's forge instantly quickened, and not only tile-eels and other animalcules, but even snails, apparently dead, and that have been kept as dried preparations from five to fifteen years,* start instantly into new life upon the application of cold water. Yet no chemist or physio- logist has hitherto satisfactorily explained by what means these ef- fects are produced. And I throw out the hint, that so instructing a subject may be followed up by those who have time and ingenuity for experiments in relation to it. Upon internal medicines we can place but little dependance, ex- cept where they have pretensions to a tonic power, are moderately cardiac, or tend to equalize the sensorial or circulating fluid. The chief tonics in use among the Boerhaavians were the ser- pentaria and contrayerva, on account of their systematic objection to the bark. The tonic power of these,' however, is but feeble; by their stimulant property, they sometimes prove diaphoretic: but even as cardiacs their place is better supplied by other medicines; and in proportion as the bark has established itself, they have gra- * Spalanzani, Hist. Nat. Tom. n. ch. iii. Phil. Trans. 1774, p. 432. 142 HiBMATICA. [CL* nI* ' dually fallen into disrepute. Yet even this last seems to be follow- ing the same track in the opinion of some practitioners of the pre- sent day, who have withdrawn all confidence in it, and undertake to affirm that it has uniformly done more mischief than good, but this is strangely to set aside the wisdom of former times, and to misconstrue the train of phenomena before them. Bark, like every other medicine, is necessarily injurious when injudiciously made use of; but there are few, if any, medicines of more importance, even in typhus, when there is a fit opportunity for employing it. Where the stomach is irritable, and will not retain it, or so feeble in its secernent power as not to digest it, and, particularly, where there is a tendency to local accumulations, it ought unquestionably to be avoided, till these symptoms are subdued by other means. But where there are no such objections it cannot be begun too soon, though it should not be pressed in such large doses as in the more rapid course of yellow fever. And where the bark cannot be made to sit easy on the stomach, its place may be well supplied with co- lumba, either in powder or infusion. If the skin be greatly heated and dry, either of these medicines may be combined with nitre or a solution of the acetate of ammo- nia, the first of which was a favourite compound with Baron Haller and his disciples ;* and if the prostration of strength be considera- ble, we may employ camphor or wine in conjunction with tonics. Camphor has, indeed, been united with medicines of very diffe- rent powers; as with large doses of nitre which Haepel seems to have found highly serviceable;! or nitre and calomel, which was at one time a favourite practice in Germany ;J or, which is far better, with cinchona, a combination peculiarly recommended by Lasonne as increasing the energy of each, in which opinion he is joined by Dr. Cullen. Camphor, however, is in itself a highly valuble medi- cine on the present occasion, and cannot well be given tco soon. It calms the low delirium, produces a genial glow on the surface, and seems to act as a steady, permanent cordial. In our own country, however, it is rarely employed in doses suf- ficiently large to be of service, as I have already had occasion to observe. Giseke was accustomed to begin with half a drachm, and increase the dose to a drachm, three or four times a-day or often- er.§ It was given with equal freedom by Stoll,|| Salle,1F and Cham- bon de Montaux :** and Collin after several hundred trials affirms, that he has never in a single instance found the pulse quickened, or * Haenel, Epist. ad Haller. t Epist. ad Haller, H. % Abhandlung von der Wirkungen des Camphors und Calomels in anhaltcnden Fiebern. i Abhandlungen, &c. || Rat Med. m. 89. tf N.

It has by many practitioners been united with some acid ; and in the form of an acetum camphoratum, was atone time a very favourite, and no doubt effective, medicine in Germany.* Acids, indeed, of all kinds, and acidulous drinks, are of great benefit in typhus. They allay the heat, tranquillize the restless- ness, support the strength, and oppose the tendency to putrescency. The muriatic was preferred by Sir William Fordyce, but the sul- phuric appears to be equally efficacious, and is much pleasanter. The best cordial is wine, and it must be given in proportion as the living power flags. We must be cautious, however, in first ad- ministering it; for its very stimulus produces exhaustion, and con- sequently increased torpitude : and we should invariably recollect, that when we have once commenced with its use, we can never leave it off; and should hence begin with such doses only as maybe safely persevered in, or even increased if necessary. Under the influence of Dr. Brown's name, both wine and spirits were lately given in enormous quantities ; and it is possible that in a few instances the practice may have been successful: but the risk is great and empirical; yet by no means of so late an origin as Dr. Brown's name would incline us to believe : for Borelli, Chambon de Montaux, and Reidlin gave it quite as largely, and at least with as much success. Borelli prescribed it in injections ;t Reidlin assures us that he cured a patient by administering a large dose of spirit of wine,| upon which Brown does not appear to have ventured; and we are told by another writer long before Dr. Brown's time, that he completely succeeded in conquering a typhus by making his patient drink wine to ebriety on a critical day.§ Of phosphorus, which was also a famous cordial at one time, I can say nothing.|| The same remark will apply to the use of opium, which appears, in many cases, to be of less service in typhus than in many other species of fever, and by no means entitled to the unmeasured eulo- gy bestowed upon it by Dr. Home, who contended that in every case of typhus it was the most useful medicine we can have re- course to; that it procures rest without any inconvenience ; and that it is more to be depended upon than camphor, castor, the seda- tive salt of Homberg, or any other medicine of the same class.1T It is best given in combination with camphor; and there is ground for the assertion of Lasonne and Halle, that, thus united, it produ- ces less confusion of the head and disturbance in the dreams : and, * Ludvvig, Adversaria, I. i.

III.-OR. I. so far as I have seen, it agrees better with the young than with those of middle life. Antimonials are a doubtful remedy : they tend to throw the ac- tion towards the surface ; but, as relaxants, they tend at the same time to diminish the tone of the muscular fibre. It is not often that they can be employed with advantage. Blisters, judiciously inter- posed, will be found, in many instances, a useful auxiliary, and es- pecially where the head is much affected ; but the body should not be covered over with them, as is often the case from head to foot, so as to be highly distressing to the patient, and to exhaust the lit- tle irritability he has left. Cataplasms or bottles of hot water ap- plied to the feet, when the circulation is unequal, will often be a better practice. Yeast, as an antiseptic, was strongly recommended to be taken into the stomach by many practitipners about twenty or thirty years ago, and numerous cases were published of the wonderful cures which it performed. Of late it seems to have fallen into an unme- rited neglect: it is a simple remedy, easily procured, and worth a more general trial. During the entire course of the fever, from the time the bowels have been sufficiently evacuated, the patient may be allowed animal broths and jellies in alternation with the farinacea: he should be lightly covered with bed-clothes ; his chamber should be freed from all unnecessary furniture; his sheets and body-linen be frequently changed, and be instantly taken out of the room; as should also the egestions of every kind. Above all things the chamber should be freely ventilated, which is infinitely the best way of purifying the air, and dissolving the febrile miasm as it issues from the body : upon which subject we have already touched. Where the ward or chamber is large, or the sick are remote from each other, simple ventilation by opening the opposite windows, or the windows and door, will be sufficient. But where the wards are small, or may not admit of sufficient ventila- tion, or the patients are numerous, fumigation with nitric or muriatic acid should not be neglected. At present we have no reason for a preference, except that the vapour of the former appears to be rather more volatile and penetrating. Of late years there have been attempts to decry the use of fumigations, and especially by M. Von Mons and Dr. Trotter, who conceive that they rather add to than diminish the septic matter of the atmosphere. On which ac- count they rather advise to sprinkle the room frequently with wa- ter, and maintain a good fire, believing that febrile contagion is much better destroyed by pure aqueous vapour than by any other means. But this conception is founded upon a double hypothesis, and an hypothesis apparently mistaken upon both points: first, that febrile miasm, and septon, or the elementary matter of putrescency, are the same thing: and, next, that this common principle is nitrous oxyde, or oxyde of azote, agreeably to the conjecture of Dr. Mil- GE. IV.-SP. II.] SANGUINEOUS FUNCTION. 145 chell. Of septon, however, we know but little ; yet from the es- tablished power of hydrogene in exhausting or destroying animal irritability, it is more probable that M. Morveau's conjecture of its being a combination of hydrogene with azote rather than of oxy- gene with the same, is the real fact. But be this as it may, we have no more reason for believing that febrile miasm consists of either of these, than that it consists of animalcules of a peculiar kind, as was once contended for by Dr. Chandler. Febrile miasm we have reason to believe is a peculiar and spe- cific production ; the chief properties of which I have already en- deavoured to point out. Pure air unquestionably dissolves it; and hence there may be other gases capable of dissolving it also, and even more readily; or which, combined with pure air, may render the latter a speedier and more powerful solvent. And it is proba- ble that the vapours of the mineral acids act in this manner. In this respect they may be useful; but if ever employed to supersede ventilation, the opinion of Dr. Trotter that they do more mischief than good will be completely established. The aromas of volatile plants are of no benefit whatever; and if the fumes of tobacco were ever serviceable in the plague, it was most probably, as Dr. Cullen conjectures, from their exhilarating the spirits like wine or opium, and diminishing the irritability. SPECIES III. ENECIA SYNOCHUS. Sgnochal jFefcer. COMPOUNDED OF CAUMA AND TYPHUS : IN ITS COMMENCEMENT RESEMBLING THE FORMER ; IN ITS PROGRESS THE LATTER. It is not necessary, after our copious histories of the two preceding species, to follow up the present, which is a mixture of both, through a detailed description of its course. It is certainly the most com- mon form under which continued fever makes its appearance in our own country ; for it is but rarely that cases of fever occur which preserve a strictly inflammatory character from the beginning to the end. It is in fact an inflammatory fever bent out of its proper career, often, perhaps, by the temperament upon which it has to act; but still more frequently, as Dr. Brocklesby has well observed, by confined and vitiated air, and hence dropping its inflammatory pretensions in the middle of its course. Its causes are therefore the same as those that produce inflammatory fever. Dr. Cullen has entered it into his catalogue of genera after Sauvages and Linneus; but with a doubt whether he is correct in so doing. " Since many VOL. II. 19 140 HJEMATICA. [cl. Hi.-OR. t fevers," says he, « are neither altogether inflammatory, nor alto- gether nervous, they cannot be referred either to the synocha. (cau- ma) or the typhus : and I have hence inserted ^e genus synochus whose type is frequently seen in this country Yet between the typhus and synocha I cannot place any accurate limits ; and doubt whether they should in fact be deemed genera or have a different place allotted them." And in his First Lines he observes, I am disposed to believe that the synochus arises from the same causes as the typhus, and is therefore only a variety of it. 1 o me it ap- pears rather to arise from the same causes as the cauma, tor it com- mences with the cauma-type. The proper rank for all of them appears to be that of species; and the present system in the text- book, in allotting them this character, steers just a middle course between Dr. Cullen's actual arrangement and his real opinion. And in this view it is distinctly regarded by Dr. Stoll, who sometimes describes it as an inflammatory fever assuming a putrid guise; some- times as equally inflammatory and putrid ; and sometimes as an in- flammatory fever passing into a sahurral fever.* By Kausch, and other German pathologists, it is hence denominated febris inflamma- torio-putrida.t It is, in many instances, the inflammatory typhus of Dr. Armstrong. Occasionally it shows a considerable tendency to terminate its course abruptly by a critical sweat; it is sometimes peculiarly mark- ed with yellowness of the skin ; sometimes with great stupor of the head ; and sometimes with inflammatory tension of the peritoneum. And it hence furnishes us with four varieties : x Sudatorius. Carried off by a critical sweat Sweating synochus. in an early stage of its progress. € Flavus.

The symptoms of the first variety open with great violence. There is usually an intense pain in the head with a vehement vomiting and purging, which is rarely removed, and sometimes aug- mented, by an emetic: the skin is peculiarly dry and hot. The balance of the circulating system is here greatly disturbed, and there is an evident determination of blood to the head, and probably to the liver. Like the yellow fever, it rushes forward rapidly to a state of great sensorial debility ; and is best checked in its progress * Rat. Med. m. p. 97. 106. 113. iv. 61. t Gruner, Almanack, 1788. p. 37. GE. IV.-SP. FT.] SANGIIVEOUS FUNCTION. 147 by a free use of the lancet, which more than any thing else takes • off the tendency to congestion, and the hardness from the pulse. A diaphoresis commonly breaks out soon afterwards, which proves critical, and should be maintained by diluent drinks, and small doses of antimonials or other relaxants. In the yellow-tinged synochus there is a high degree of hepatic irritation, and consequently an excessive secretion of bile, part of which is resorbed and carried into the system : whence Galen de- nominates it synochus biliosa.* It is found chiefly in the summer season among young persons of a bilious habit, and is generally pro- duced, like the genuine cauma, by too violent exertion under a sul- try sky. It is accompanied with intolerable thirst and sleeplessness. in few words, it is a causus or ardent fever without any apparent remission; its symptoms, with this exception, are the same, and the same mode of treatment is demanded : for which the reader may turn to the second species of the preceding genus. While the symptoms rage violently, there is sometimes a great determination to the head, with a sudden exhaustion of sensorial power; and hence, notwithstanding this local affection is more se- vere and confirmed than in the first variety, there is a dull and obtuse, rather than an intense and pungent pain. It is the synochus soporosa of Guarinon and Sauvages; and the continual fever of Sydenham for the year 1763. Among the chief symptoms, says he, was a coma, for the patient soon became drowsy and obscurely de- lirious. Occasionally, however, it was a direct lethargy, which continued for two or three weeks, during which nothing but a vio- lent noise would rouse the patient; when after opening his eyes and being persuaded, perhaps, to take a little food or some medicine, he again fell into a sleep so profound, that Sauvages calls it a febrile cataphora. In some cases, however, instead of a lethargy, there was a low muttering delirium, in which the patient spoke incongru- ously and with fretfulness, with short snatchings of stertorous sleep in- terposed. The fever rarely terminated in less than fourteen days; and, when the lethargy prevailed, generally ran on to twenty-one or even thirty days. The first symptom of recovery was usually a capricious longing for some absurd kind of meat or drink. The head for many days still discovered great weakness, and even the muscles were incapable of supporting it in an erect position. Warm cordials were always mischievous: a free and repeated use of the lancet with brisk purgatives formed the best plan of cure, with diluting diaphoretics afterwards. Sauvages asserts, that blistering the head was serviceable. Epithems of ice-water over the whole head, repeated as soon as they become warm, would probably have proved far more beneficial, as soon as the vessels of the head had been sufficiently emptied. We find the same fever still more frequently commencing with a like tendency to the peritoneum instead of to the hea*', which runs * De Differ febr. cap. n. De Crisibus, cap. n. 148 MMAT1CA. tCL- llI-°R* L rapidly into a state of inflammation, with an imperfect att®™P* ** suppuration; and especially where this membrane has oeen«xu ed by a sympathetic action with the uterus or any other adjacent or- gan, or by exposure to the atmosphere in consequence ot a wouna through the abdominal integuments. And hence this disease occurs occasionally in cases of tapping for a dropsy of the abdomen, and still more frequently after labour: on which account it is com- monly known by the name of peritoneal, puerperal, or child-bed fever. From the days of Hippocrates to those of Boerhaave and Van Swieten, the uterus was supposed to be the chief seat ot inflam- mation when the disease arises from this cause. But there is now no question that it originates in the peritoneum itself, and that the uterus is often very little affected; and this too, though the inflam- mation should spread, as it often does, to other organs in the vicinity. The disease usually commences about the third day a.ter de- livery, or a wound made through the abdominal integuments by ac- cident, or in tapping for a dropsy of the abdomen ; though some- times it occurs rather later. It is marked by all the common symp- toms of a severe febrile incursion, in combination with the tenseness and tenderness of the belly. The muscles of the back and hips are in great pain; and as the diaphragm is affected by contiguous sym- pathy, the breathing is also short and laborious. The head rarely suffers much at first, but in the progress of the disease is apt to be- come stupid and comatose. The flow of the milk and of the lochia are suspended: the stomach is sometimes, but not generally, troub- led with sickness, and frequently discharges an offensive porraceous suburra; and a troublesome diarrhoea attacks the bowels. To account for the inflammation of the peritoneum, it is only ne- cessary to recal to mind the readiness with which, in particular con- stitutions, or states of excitement from various internal or external causes, inflammation often takes place in interior cavities, and the rapidity with which it spreads over every part of them. It is to this principle alone we trust in effecting a radical cure for a dropsy of the tunica vaginalis of the scrotum. The cavity here is small, and we are not afraid of serious mischief; but were it as large as that of the peritoneum, he would be a bold operator who should ven- ture upon a like mode of cure, notwithstanding that the process of adhesion, so much more easily effected in the scrotum than in the abdomen, might diminish the chance of danger. In the opinion of Mr. John Hunter, the disease takes place in con- sequence of an injury done to the peritoneum, as forming a cavity, by which its present state is either suddenly changed or rendered imperfect. The injury done to the peritoneum in the case of wo- men after delivery, he ascribes, as his sentiments are delivered by Mr. Cruikshank, to two causes. Sometimes it proceeds from a want of disposition in the womb to recover itself after labour; by which the peritoneum, as a cavity, must necessarily be affected. At oth- er times from a too sudden emptying of the abdomen ; whence the peritoneum cannot always recover itself so as to be properly adopt- GE. IV.-SP. HI.] SANGUINEOUS FUNCTION. 149 ed to its new condition. This last cause, he observes, may also hold with men after the operation of the paracentesis. But, in them, be- sides the sudden emptying of the abdomen, there is the additional circumstance of a wound, which renders the peritoneum, as a cavity, imperfect. When an inflammation of the peritoneum occurs, it most frequently happens, as he still farther remarks that it spreads over all the cavity of the abdomen. An extravasation of fluids takes place into that cavity mixed with pus. The different viscera ad- here by their peritoneal coats. The intestines are distended with air. And the irritation, thus induced, kills the patient long before granulations or an obliteration of the cavity in the second method can occur.* Neither of these two causes, however, by themselves will often, if ever, produce the fever before us, or even peritoneal inflamma- tion alone. For the uterus is perpetually exhibiting a morbid en- largement, without a disposition to recover itself; and the abdomen, sudden evacuation, while no such fever ensues. There must co-ope- rate a peculiar temperament, or a peculiar condition of body at the time ; and, in puerperal patients, there is especially the general pyrec. tic excitement which necessarily follows, upon the very great change in various organs which takes place upon delivery and the transfer of accumulated action from one organ to another. Another accessary is also frequently found in the constitution of the atmosphere ; for whatever change is most calculated to produce fever from a morbid excitement of the abdominal viscera, cannot fail to co-operate in the production of this disease from a local cause. I have already observed that such a change most usually occurs in autumn, and have stated the grounds on which it depends under the history of epanetus aittumnalis, to which the reader may turn at his leisure.! And hence, so far as I have observed, a tendency to peritoneal or puerperal fever occurs more frequently at this season than at any other; and on this account it is said by some writers to occur occa- sionally as an epidemy.J There is much reason, indeed, for regard- ing it in this last view; for as most of the auxiliaries that unite in the production of contagious miasm are present in a lying-in cham- ber, such miasm is frequently the result; often indeed, as we have reason to believe generated, after the manner of typhous miasm, and completely elaborated in the circulating and secreted fluids of the patient herself. Of this fact there can be no longer any ques- tion, after the accounts of the disease published by Dr. Gordon of Aberdeen, and Dr. Young of Edinburgh, as it appeared in the lying- in infirmaries of these cities; in which woman after woman conti- nued to be infected to a very great extent, and especially wheret hey had had close communication with puerperal patients, or had even been attended by nurses or midwives who had previously attended * Edin. Med. Comment. Vol. ill. 322. t See Vol. n. CI. in. Ord. I. p. 93. t Clark, Edin. Med. Comment. Vol. in. 150 HEMATIC A. 0L- ^I•-, the latter without sufficiently changing their malignant dress. This disease was only subdued by the ordinary means employed to exter- minate contagious miasm, such as great cleanliness, repeated change of sheets and body-linen, free ventilation, and a total separation oi those who were labouring -under the disease from those who were about to be confined. In all kinds of contagious fevers we find that some persons are more liable to be infected than others from incidental circumstan- ces; and, as I have already had occasion to observe in laying down the laws of febrile miasm so far as we are at present acquainted with them, the miasmic corpuscles are modified in a few of their proper- ties by the accessaries to which they are exposed, or by which they are produced. And by bearing these facts in mind, we shall have no difficulty in accounting for the limitation of this contagious fever to puerperal women, and the exemption possessed by persons who are not under the same circumstances. For, operative as the miasm unquestionably is when the predisposition exists, and the abdominal organs are thrown out of the balance of healthy action, it is inert where no such predisposition is to be found, and these organs are in elastic vigour. But whether the miasm thus generated be the common febrile miasm we have contemplated in several of the preceding species, merely modified in its powers by accidental circumstances, or a con- tagion specific and peculiar to itself, is a question which, at present, we have not the means of determining. I have said that in the inflammation which takes place, there is an imperfect attempt at suppuration. The fluid secreted or effused is usually a whey-like material, or milky ichor, or, as Mr. Cruik- shank has described it, an extravasated matter mixed with pus. But Dr. Hulme* asserts, that he has sometimes found genuine pus apparently secreted without ulceration; and Dr. Meckel informs Baron Haller, that he has witnessed the same very extensively.t The nature of the fluid will, indeed, entirely depend upon the vehe- mence and rapidity of the inflammatory process. Where tljis is less violent, the secretion, as from the surface of other mucous mem- branes, may be purulent or even genuine pus, and has sometimes amounted to several pints; but, where more violent, it will be a milky, caseous, or whey-like serum. It is rarely however so mild and temperate in its march as to produce pus; often running on, as Dr. Hulme has observed, to a state of gangrene at once : and in some instances has been found to involve the intestines, omentum, and all the neighbouring viscera, in the common mis- chief, as has been abundantly established by post-obituary examina- tions.;}: And hence, the uterus itself has sometimes participated in * Treatise on the Puerperal Fever. t Epist. ad Haller Script. Vol. m. X Hulme, ubi supta. De la Roche, Rccharches, &c. GE IV.-SP. III.] SANGUINEOUS FUNCTION. 151 the inflammation, and has shown pus or gangrene according to the vehemence and rapidity of the morbid influence.* The general treatment of this disease should very closely resem- ble that already laid down for the severer varieties of the malignant remittent, which it very much resembles, with the exception that the fever is continual instead of being relaxant; and that the local irritation is seated in the peritoneum instead of in the liver or any other organ. This inflammation must be subdued, and that speedi- ly, or the patient will perish; and hence, abstraction of blood and calomel purgatives are the arms on which we have chiefly, if not solely, to depend ; and both should be employed decidedly, and to as great an extent as we dare. Eighteen or twenty ounces of blood should be drawn from the arm, as soon as possible after the commencement of the disease, and repeated within twelve hours if necessary, and the strength will allow : but if venesection have not taken place before the third day, the debility will have gained so high an ascendency, and the general symptoms put on so putrescent a complexion, that little be- nefit is to be gained from it. The bowels should at the same time be moved by six or eight grains of calomel given in the form of a pill; and the same preparation, to the amount of three or four grains, should be continued every six hours till the tension and sore- ness of the abdomen have abated. It happens not unfrequently, however, that the patient's frame is so weak and delicate that we should risk more by drawing blood generally than even by leaving the case to nature ; as it does also that the stomach and bowels are from the first in a very high degree of irritation, with violent purging and vomiting, and will not bear any additional stimulant. Our wisdom is here to yield to circum- stances, and let the general rule admit of particular exceptions. In- stead of the lancet, we have recourse to leeches, and in this manner remove twelve ounces of blood at the least; and with smaller do- ses of calomel we must unite opium. It does not follow that calo- mel in such a combination will increase the irritation of the stomach or bowels ; I have often seen the contrary ; and that by the exhibi- tion of two grains with one grain of opium, repeated every five or six hours, the irritation has yielded to the commencement of a new action. Warm and anodyne fomentations to the abdomen are usual- ly prescribed at the same time, and are often found palliative ; but the common mode of applying them makes the bed wet and gives great fatigue to the patient. And hence, I have ordinarily pre- scribed a large piece of folded flannel wrung out forcibly in as hot water as can be borne, to be applied over the whole of the pubes and abdomen, and covered by a broad flannel or linen swathe pass- ed under the loihs and folded over the epithem of reeking flannel, which is to remain for many hours, or till it becomes dry. All that is wanted in this application, as in a common bread-and-water poul- * Bang, Act. Soc. Haffn. I. 152 HjEMATICA. [CL. M.-OR. I. tice, is warmth and moisture; the flannel answers the Panose as well as the bread; and whilst I do not recollect a single instance^in which this application has not been soothing and ^serviceable, 1 have never met with a case in which a chill has been complained of. In the mean time, a diapnoe or breathing perspiration °n the sur- face should be attempted by small doses of ipecacuan united with opium in the form of Dover's powder, and with h\addltlon °f.a solution of acetate of ammonia;* and if the debility be very cons - derable, we may employ free doses of camphor, beginning with half a scruple, and proceeding to half a^drachm at a time, every four or five hours, with great advantage. . If this plan should not answer, and the skin be still hotter, drier, and more pungent to the touch, the pulse quicker and more wiry, and the tongue deeper furred, it may be adviseable to exchange epithems of hot for those of cold or even ice-water, as already re- commended in cases where the head is chiefly affected instead of the peritoneum. I freely confess that I have not tried this plan myself hitherto, but it is strongly recommended by Loeffler and other physicians of great repute; and as it is a practice in common use in our own country in the case of flooding, without any evil re- sulting from it, we have no reason to expect any evil in the case before us; for the sensibility is here still more obtunded than in flooding, and nearly as much as in deliquium. * Beytrage zur Wondarzneykunst.

The diseases comprised under this order are sometimes called Lo- cal Inflammations ; as the term General Inflammation is, by a few writers, and particularly by Dr. Fordyce, applied to Cauma or In- flammatory Fever. In the present text the ordinal name made choice of is phlogotica, from ?Asy*», " incendo," " ango." Linneus employs phlogistica from the same root; but as the chemists have long since laid hoW of phlogiston, and the term, though lately dis- used, has a chance of being restored, the derivation phlogotica seems preferable. Dr. Cullen has phlegmasia, after Galen and Sau- vages ; but as phlegmasia, and phlegmatic, from the same source, im- port, in common medical language, a very different and almost an op- posite idea, the author has also purposely passed by this term in or- der to prevent confusion. The nature of the fever accompanying the inflammation cannot enter into the definition; for this will vary v/ith the nature of the inflammation itself, and not unfrequently with the structure of the organ. But we may make this observation, that the symptomatic cauma, or symptomatic inflammatory fever, seems to Lave followed the fortune of this fever in its idiopathic state ; and to be as much less common in the present day, compared with what it was formerly, as we had occasion to observe the sim- ple cauma is when treating of that disease. Such is also the remark of Mr. Hunter. " I believe," says he, " we have much less occa- sion for evacuations in inflammation than there were formerly; the lancet, therefore in inflammation, and also purgatives, are much more laid aside.1'* * On Blood and Inflammation, p. 227. vol. N. 20 • 154 HjEMATICA. [CL. IlI.-OR. II. When an inflammation takes place near the surface of the body, (here is not only heat and pain, or soreness, but more or less swell- ing, hardness, and redness, and we hence infer the existence of these last symptoms in inflamed parts which lie beyond the reach ot vision. Inflammation in most cases appears to begin at a point; for, at the commencement, all the local symptoms are within a very small com- pass. The spreading of the inflammation is owing to continued sym- pathy, the surrounding parts participating with the point of irrita- tion ; and in proportion to the health of the surrounding parts, and constitution, this sympathy is less. The act of inflammation seems to consist in an increased action of the vessels ; mostly, if not altogether of the extreme vessels ; for wherever inflammation appears, it may be confined to a point in which none but the smallest vessels can exist. The first act of the vessels when the stimulus which excites in- flammation is applied, Mr. Hunter supposes to be precisely similar to a blush; and to consist in a simple distention or increased dia- meter beyond their natural size ; such as we see take place on the application of a gentle friction, or of gently stimulating medicines, to the skin ; and the consequence of which is a warm glow, when limited to the degree we are now supposing; but which, if carried farther, would be followed with excoriation, suppuration, and ulcer- ation. The inflamed vessels, being thus enlarged and irritated, begin to separate from the blood they contain some portion of its coagulating lymph, together with some serum, and red globules ; and to throw these materials out on the internal surface of the part inflamed; probably through the exhalants, or, perhaps, jjybrough new ves- sels which may be now forming around them; whence the sides of the cellular membrane, which receive the effusion, become cover- ed with it, unite with the opposite sides with which they are in con- tact, and thus form the first foundation of adhesions. The increased bulk of an inflamed part is produced chiefly by this effusion; and the increased redness, partly by the larger quantity of blood con- tinued in the distended old vessels, and partly by the production of new vessels formed out of the coagulable lymph thus extravasated ; and which, by innumerable inosculations and adhesions, interpose a check to suppuration, which would otherwise most probably take place. Inflammation, therefore, consists in an increased impetus and ac- cumulation of blood in the vessels affected, accompanied with a proportionate swelling and sense of heat. The physiologists have pretty generally concurred in ascribing this accumulation of blood to an obstruction of some kind or other; but they have differed upon its nature and origin; and have not been able to determine whether it be dependent upon the crasis of the blood itself, or the resistance of the \ essels that contain it. Generally speaking, however, it has by all the schools of medi- • CL. IH.-OR. II.] SANGUINEOUS FUNCTION. 155 cine been ascribed to whatever has been supposed to be the proxi- mate cause of fever : and hence the humoral pathologists attributed it to a lentor or viscidity of the circulating fluid ; and the corpuscu- lar, to an error loci, concerning both of which we have already treated ; the cause of obstruction in the view of either hypothe- sis, being seated in the nature or misdirection of the constituent parts of the blood itself: while Dr. Cullen refers it to the same kind of spasm which he regarded as the proximate cause of fever ; and hence derived the obstruction from a constrictive resistance in the vessels of the part affected : which, he farther supposes, forms but a mere link in the tensive chain of a phlogistic diathesis, which more or less runs through the entire habit at the time of inflammation, and constitutes the predisposition to its rise and progress. " That a spasm," says he, " of the extreme vessels takes place in inflammation, is presumed from what is at the same time the state of the whole arterial system. In all considerable inflammations, though arising in one part only, an affection is communicated to the whole system ; in consequence of which an inflammation is readily produced in other parts besides that first affected. This general affection is well known to physicians under the name of diathesis phlogistica. It most commonly appears in persons of the most rigid fibres; is often manifestly induced by the tonic or astringent power of cold ; increased by all tonic and stimulant powers applied to the body; always attended by hardness of the pulse; and most effectual- ly taken off by the relaxing power of blood-letting. From these circumstances it is probable that the diathesis phlogistica consists in an increased tone or contractibility, and, perhaps, contraction of the muscular fibres of the whole arterial system."* To the first two of these hypotheses the same objections apply that we have already seen apply to them as causes of fever. That an error loci occasionally takes place, or, in other words, an en- trance of red or other particles of blood into minute vessels to which they do not naturally belong, is unquestionable ; but then this is rather a secondary than a primary link in the chain of inflammation, and consequently an effect rather than a cause, as we shall presently have to notice more at large. Yet the hypothesis of Dr. Cullen does not seem to be more satis- factory, and is especially open to the two following objections, to say nothing of various minor difficulties with which it is attended. It supposes, in the first place, as a general rule, that inflammations of every kind, however minute and circumscribed, are dependant upon a particular habit of body at the time, distinguished by the name of a phlogistic diathesis. But we see inflammations occurring in habits of every kind, and varying in many of their features ac- cording to the variety of the habit; and we see them also arise in individuals who have no such phlogistic habit or diathesis as is here referred to. And we often, moreover, see examples of this very * Pract. of Phys. Vol. iv. Sect, ccxlvii. 156 HiEMATlCA. [CL. IIL-OR. II. diathesis operating upon individuals for years, without producing any such effect as inflammation in particular parts. And we cannot, therefore, regard such a diathesis as a proximate cause of inflam- mation in general, though it may often be so of a particular kind of inflammation. Dr. Cullen, indeed, was aware of this difficulty, and even admits it. " Such a state of the system," says he, " seems often to arise and subsist for some time without the apparent in- flammation of any particular part; but such a state of the system renders it likely that a spasm may, at the same time, readily arise in any of the extreme vessels, and a particular inflammation be there produced. It does, however, appear also, that the general diathesis frequently arises from inflammation begun in a particular part."* Now this is not only to admit the difficulty but to fall prostrate be- fore it. It is to admit what at once settles the entire question. The cause and the effect are made to change places : and the phlo- gistic diathesis is as broadly stated to originate from inflammation in a particular part, as inflammation in a particular part is stated to originate in the phlogistic diathesis. But, secondly, this hypothesis seems not only to be chargeable with incongruity, but to be directly at variance with the ordinary train of phaenomena by which inflammation is accompanied. That the habit here alluded to under the name of diathesis phlogistica exists, and that very frequently, is not to be questioned; and Dr. Cullen has very lucidly described what is ordinarily meant by it. " It seems probable," says he, " that the diathesis phlogistica con- sists in an increased tone or contractility, and perhaps in an increas- ed contraction of the muscular fibres of the whole arterial system ;" —" it appears most commonly in persons of the most rigid fibres." But I believe it will be found by every one who investigates the subject, that so far from this being the habit of body in which inflammation is most frequently to be met with, it is that in which it occurs more rarely than in many others. That it occurs in it at times is unquestionable, for inflammation under some form or other occurs in habits of every kind: but if we look for specimens of larger or smaller inflammation, of deep-seated or superficial, nay, even of suppurative or ulcerative, we shall meet with them, if I mistake not, far more generally in constitutions marked by mobile and irritable than by firm and rigid fibres; in habits characterized by atonic rather than by entonic action. It is not till the constitu- tion has been broken down, and the liver rendered feeble and tor- pid by the influence of a tropical sun, that hepatitis makes its ap- pearance in its ordinary course of attack; phthisis occurs in relaxed and delicate, and not in hardy and robust frames ; psoas abscess, pe- ritoneal inflammation, struma, and those vast formations of pus which are sometimes found in parabysmic tumours or physconics, for the most part follow the same track; while the best, if not the only remedy for the innumerable host of erythematic inflammations, * Loc. citat. CL. III.-OR. II.] SANGUINEOUS FUNCTION. 157' whether erysipelatous, gangrenous, or vesicular, pernio or intertri- go, is to raise the part or the constitution to that scale of vigour the reduction of which is well known to form a common predispo- sition to all of them. That there may exist such a condition of bo- dy as an inflammatory diathesis, or a predisposition to inflammatory action of some kind or other, according to the idiosyncrasy or esta- blished habit, or some controlling accident, is unquestionable ; but such a diathesis cannot be made synonymous with the phlogistic diathesis as described by Dr. Cullen, unless there be but one kind of inflammation, and that such an inflammation as has a natural and necessary relation to the entony and rigidity of fibre which is here presupposed. The little that we know upon the subject may, perhaps, be com- prized in a few words : The standard of firm health is the best guard against inflammations of every kind, or the state in which a man is least susceptive of them; and a deviation in either direction, whe- ther towards a habit of entony or of atony, capacities him for breeding them. But it does not capacify him equally : for in the latter case they are produced far*more easily and generally than in the former. In fibrous entony, obstruction appears to take place, and inflamma- tion to follow, from an increased tendency to constriction and rigi- dity in the muscular tunic of the arteries generally, and an actual constriction in those of the part affected; in consequence of which the diameter of the tube is diminished, and the blood, though urged by a stronger impetus from behind, works onward with less free- dom than usual. In fibrous atony, obstruction takes place from the relaxed and yielding state of the vessels which admit grosser cor- puscles of the blood than what naturally belong to them, and thus become accessary to the error loci of the Boerhaavian school. But a mere error loci is not sufficient for inflammation ; since the erra- tic corpuscles are readily forced back, or pass diagonally into larger vessels from the numerous anastomoses that prevail in the arterial system. Of this we have a pertinent example in the red suffusion which frequently takes place in the tunica albuginea of the eye, which is often an effect of weakness alone, is unaccompanied with heat or pain, and consequently with inflammation, and perhaps pass- es off by the next day In addition, therefore, to the relaxed state of fibres and the error loci before us, there must be something of that irritability which is so frequently an attendant upon relaxed and mobile organs, and which produces spasmodic and contractile action in a far higher degree, though, perhaps, in irregular fluxes and refluxes, than any habitual firmness or rigidity of fibre does at any time. ..^ And as in weak parts or habits a peculiar susceptibility of irrita- tion seems to be a necessary adjunct in the production of inflamma- tion, it is possible that it may be equally necessary in the opposite state of excessive firmness and rigidity of fibre ; since this also, as just observed, will, at times, continue for years without giving rise to any inflammation whatever, and seems equally to demand an ex^ 158 HyEMATICA. [CL. HI.-OR. H. citing accessary. And hence the real inflammatory or phlogistic dia- thesis, constituting however a remote, more properly than a proxi- mate cause, is perhaps to be found in increased irritability ot the living fibre rather than an increased rigidity and vigour. Concerning then the proximate cause of inflammation, there is yet much to be unravelled. Of its remote causes and a tew of its laws, we are in some degree better informed. The remote causes may be contemplated under the three following divisions : First, some accidental violence applied to a part, so as to make a wound or bruise from which it cannot recover except by the pro- cess of inflammation, or which, at least, has a natural tendency to excite such a process. Secondly, some irritation which does not destroy the texture of the part, but merely its natural action; as pressure, heat, cold, blis- ters, pungent applications, and often fevers of every kind. Thirdly, a particular disposition to inflammation, founded, per- haps, as we have just observed, in an irritability in the morbid part itself, and which we often behold in constitutions of the best state of health; affording proof that the general %abit is not, in such cases, concerned in the morbid change. Inflammations from any of these causes will, however, partake of the character of the con- stitution ; and hence proceed kindly or unkindly, according as the constitution is in a diseased or a healthy condition. Yet the gene- ral principle of inflammation is the same in all; for we can only contemplate it as a remedial process, an instinctive effort, or exer- tion of the vis medicatrix naturae, to bring about a re-instatement of the parts nearly to their natural functions. Yet, though inflammation is uniformly the same in its principle, it often differs widely in its mode of action, and consequently in its result; for as it has a tendency to partake of the character of the constitution, and especially where it is extensive, according as the constitution is healthy or unhealthy, so will be the nature of the in- flammation and the diversity of its progress. Healthy inflammation consists probably of one kind alone, and is no farther divisible than into different stages of a restorative action, the effect of an instinctive stimulus rather than of morbid irritation. Unhealthy inflammation consists of many species, for numberless are the diseases that effect the health of the constitution; and con- sequently that may influence the character of the inflammation, by superadding peculiarities or specific actions of its own: though it is often affected also by the particular condition of the part in which the inflammation takes place. And hence it is no uncommon thing for particular parts to run into particular inflammations with the character of which the constitution has little concern; such as those that are occasionally found on the skin, particularly the erysipela- tous, as they are commonly but not quite correctly denominated, and which we shall presently have to describe under the name of erysipelatous erythema. Simple or healthy inflammation is capable of producing three CI.. III.—OR. II.] SANGUINEOUS FUNCTION. 159 different effects, which, where the whole take place healthily, fol- low in regular order, and constitute so many stages. These are adhesions of the parts inflamed, suppuration, and ulceration ; to which three, different effects Mr. Hunter has given the names of the adhesive, the suppurative, and the ulcerative inflammation. There is good reason for this division into different heads; for although, where the whole take place healthily, they follow in the order now enumerated, yet the whole do not always take place either healthily or unhealthily ; nor is the order thus enumerated in every instance attended to. For pus, as we shall have occasion to observe more largely hereafter, is often produced when there is no adhesive inflammation; and ulceration, when there is neither adhesion nor suppuration: while occasionally the suppurative and adhesive inflammations take place simultaneously; the former be- in°- hurried on before the other has completed its own bounds, as is often the case in peritoneal inflammation after child-birth. The degree of violence also with which the inflammation commences, produces a considerable influence upon these points ; and the nature of the parts themselves still more. With the nature of the parts that constitute the chief fields of in- flammation, it is of high importance that we should make ourselves deeply acquainted from the first, that we may be able to determine concerning the particular course the inflammation is likely to run, and regulate our treatment accordingly. And it is of still farther importance that this subject should be attended to on the present occasion, because it is on this distinction of parts, producing a natu- ral tendency to distinct inflammations, that the genera of the order before us are principally constructed. The whole of the observations of Mr. Hunter upon this interest- ing point are entitled to the most patient study, and cannot be too closely committed to memory. In the present place I can only re- mark, that, in treating of inflammation, he divides the body into two parts : firstly, the circumscribed cavities, organs, and cellular membrane which connects them ; and, secondly, the outlets' of the body, commonly called mucous membranes, as the ducts of the glands, alimentary canal, and similar organsjfcle distributes in- flammatory affections, as 1 have just observed^nto three sorts, ad- hesive, suppurative, and ulcerative. Adhesive inflammation belongs chiefly to the former of the above two parts of the body, where they are deeply seated; and appears intended to take place for the pur- pose of preventing suppuration. It applies, therefore, peculiarly to that genus of the present order which we shall denominate em- fresma, and which will embrace the visceral organs, allowing for one or two exceptions that are occasionally interposed. Suppura- tive inflammation belongs chiefly to the same division of parts placed near the surface ; and consequently applies to the two genera here denominated phlegmone and phyma, embracing small cutaneous abscesses of various kinds. The ulcerative inflammation belongs chiefly to the second order of parts, as the mucous membranes and J 60 H.EMATICA. [cL.lH.-OR.il- outlets; and hence applies principally to the genus erythema, or inflammatory blush ; often, but improperly, called erysipelas, which is an exanthem or eruptive fever, accompanied with erythema. It also applies to that peculiar inflammation which characterizes the whitloe, and will be found in the present arrangement under the genus phlysis. Deep-seated suppurative inflammations and absces- ses cannot well be placed in either of the genera we have thus tar noticed; and have a claim to be considered by themselves^ lhey are hence included in the genus apostema, with which the order will be found to open. Inflammation, therefore, is influenced by the nature of the part in which it takes place. It is also, as we have already observed, equally influenced by the nature of the constitution itself; and, thirdly, it is influenced by the nature of the remote cause. And we may add, that, where the inflammation is regulated by the constitu- tion, and the constitution itself is healthy, specific irritants will not change the nature of the inflammation, but only determine its situa- tion, extent, duration, or some other peculiar property. But where the constitution is unhealthy, or predisposed to any particular mor- bid action, as that of erysipelas, putrid fever, or plague, (for some individuals receive even the plague much more readily than others,) as soon as the specific virus is communicated, the disease will de- generate into a mixture of both, and discover its double source ; it will give proof that a specific inflammation has been set down upon a constitution of a peculiar kind, and will partake of the nature of both. In consequence of which, the specific properties will by no means be so distinct or well formed as if they were to appear in a sound and untainted constitution. Thus, if the constitution have a susceptibility to become putrid, and the small-pox attack it, the inflammation will be that of the small-pox combined with the constitutional tendency to putrescen- cy; which will so far affect the action of the small-pox as to inter- fere with the specific difference of its inflammation. In consequence of whieh, the pustules will spread, but not suppurate, and assume a livid hue, and perhaps prove fatal; while if another person posses- sing an uncorrupt jfcd, so to speak, unbiassed constitution, be in- oculated even witrTthis mixed virus, the variolous principle will separate itself from the principle with which it is combined, im- prove with the improvement of the new soil, and yield a crop of genuine and unadulterated pustules. In like manner vaccination is, generally speaking, a specific pre- servation against the small-pox. But it sometimes happens that it is not so; and that the small-pox is caught and makes its appearance many years after vaccination has been resorted to,' and performed with all possible circumspection. And it generally happens in such cases, though not always, that a mixed or hybrid disease, a sort of degenerate small-pox of a milder character than the true, is hereby produced. The remarks just laid down will furnish us with a clear and suffi- CL. III.-OR. II.] SANGUINEOUS FUNCTION. 161 cient clue to these singular and interesting facts. Some persons have a peculiar predisposition to small-pox, which is by no means easily eradicated, and far less so than in others. Vaccination, which permanently counteracts the predisposition among mankind in gene- ral, does not permanently counteract it here. It introduces a new but less rooted diathesis, and the former is rather suppressed than extirpated. In process of time the predisposition revives, re-ac- quires its anterior influence, and the moment it comes in contact with variolous contagion, subjects the system to smail-pox. But while the variolous diathesis is thu- again become predominant, the vac- cine diathesis has not altogether lost its hold; and the disease, as in the preceding cases, is a mixed product of both causes in co-operation, or rather in antagonism. It is small-pox raised upon a constitution not yet totally liberated from the influence of vaccination ; I say, " not yet totally liberated," because we occasionally meet with instances in which the constitution, little open to the impression of the vac- cine disease, even when first communicated, becomes in time lib- erated from its influence altogether, and receives the small-pox, after vaccination, as freely as if it had never been vaccinated, and with a violence that proves fatal in a few days. It is a wise and beneficent law of providence, and affords an in- controvertible proof of the existence of an instinctive remedial power, that inflammation, wherever seated, is always more violent on the side of the inflamed point nearest the surface, and shows a constant tendency to work its way externally rather than internally. This law applies equally to the thorax, to the abdomen, and to parts which lie close to the different outlets of the body. Thus, if an inflammation attack the peritoneum covering an intestine, and ad- hesions are hereby produced between the two, the inflammatory action works upwards through the thick walls of the abdominal muscles, while the proper coats of the intestines in most instances remain sound. This, indeed, is not always the case ; for the in- flammation may be so violent as to pass in both directions with great rapidity, or some accidental circumstance may guide it inwardly; but it is so common as to form a general ruie. We see the same thing in the obstruction of the natural passage of the tears produc- ing a fistula lachrymaiis; for here the ulceration points externally to the inner angle of the eye, while the inside of the nose defends itself by becoming thicker; so much so, in many cases, as to block up the cavity of the nostril, a*nd produce irfosculations with ihe sep- tum ; which has been an occasional cause of failure in the usual operation for this disease.* We even find that if an abscess form in a frontal sinus from an obstruction in its duct, the matter will rather work its way externally through the frontal bone than des- cend into the nose. In like manner, if an inflammation attack the cellular membrance on the outside of the rectum near the anus, * See Hunter on Blood, Inflammation, Lc. Fart 11. Chap. ix. VOL. II. 21 162 HvEMATICA. [CL. III.-OR. II. although the latter be in contact with the inflamed part, the in- flammation will extend to the skin of the buttock, while the gut it- self is often but little affected. For the same reason we behold eruptive fevers conducting the specific poisons which excite them, as small-pox, measles, rosalia, or scarlet fever, and even the plague itself, to the surface of the body, rather than throwing them on parts that are deep-seated and vital. The cancer is said to form an exception; but even here the progress of the disease towards the surface is quicker than its pro- gress towards the centre : while syphilis exhibits something of a similar disposition though not in an equal degree. It appears then that simple or healthy inflammation is a remedial process for restoring a part to soundness when affected by a morbid impression that has a tendency to injure or destroy it: and that the first stage of this process consists in the effusion of a coagulable lymph, which binds the weakened organization into a closer bond of union, creates new vessels, and consequently introduces new life. If this effort do not succeed, and the morbid action still continues its pro- grees, the affected part dies to a certain extent; but the coagulable lymph which has been thrown out, and introduced new vascularity around it, still sets a boundary to the destructive career, and prevents it from spreading into the neighbourhood, or at least from spreading as far as it otherwise would do. When, however, a part is thus killed or destroyed, it becomes a substance foreign to the body, and must be removed, and have its place supplied by a formation of new living matter. The process of suppuration, which we shall explain under the genus afostema, prepares equally for the removal of the dead matter and the formation of that which is to fill up its post. This, however, is the progress of healthy inflammation alone ; for, as already observed, in unhealthy inflammation, the morbid ac- tion will often run on to the ulcerative process or last stage at once ; or the adhesive, or the suppurative may intermix with it; or all may imperfectly take place together. In attempting the cure of inflammation, our first endeavour should be to obtain what has been called a resolution of the general en- largement; or, in other words, a restoration of the part to its state of former health, without the necessity of its going through the entire range of the inflammatory process. And in doing this we are to be guided by the principle of being able to make a new im- pression upon the part, and to oppose a healthy or remedial to an unhealthy and mischievous action. The nature of the cause must hence be sedulously inquired into, for till this is ascertained and re- moved, it will be in vain to expect that resolution can take place, and where we can speedily accomplish such removal, resolution will often follow spontaneously; for the animal economy having a disposition in itself to discontinue diseased action, such action will readily subside upon a disappearance of the cause that maintains it. And hence by taking off the venereal action by the use of mercury in the case of a bubo, the inflammation will gradually cease, pro- CL. 1II.-0R. H.] SANGUINEOUS FUNCTION. 163 vided no other morbid action has already arisen and united itself with the syphilitic. Resolution, however, is not always to be attempted; for there are many cases in which the attempt would be in vain, and possibly a few in which it would be improper. It is not to be attempted in accidents where there is a considerable exposure of the injured part; and still less in accidents where the part has been killed by their violence : for in these, suppuration is the first natural step to a cure, and we cannot prevent it if we would. Where inflammation arises from a morbid predisposition in the constitution, and belongs to the description which has been called critical, there is some doubt, and much demand for circumspection: and in this case resolution is called repulsion. If the inflammation be really a concentration of the constitutional complaint, which, by being driven from the part fixed upon, may be again diffused over the entire frame, and in waiting to fasten on some other part, it will often be better to encourage its stay. But the determination even in this case must be subject to the two following conditions : first, that the inflammation so concentrated will readily admit of a cure ; and, next, that the part on which it fixes is not of vital importance; for otherwise the remedy ma}' prove worse than the disease. When resolution is determined upon, independently of removing the cause of the inflammation, we may advantageously follow up its effects by all the common modes employed for this purpose, ac- cording to the nature of the particular case. The undue degree of action may be diminished by bleeding and purging ; the distension by local applications that tend to contract the diameter of the vessels, as cold, and metallic or other astringents; and if along with the distension there should be great pain, narcotics and relaxants will generally be found useful auxiliaries. To these in the present day are often added nausea and vomitmg, the former of which operates by lowering the action of the vessels; Ihe latter by giving a ten- dency to a new action. The nature of the case must determine our choice. GENUS I. APOSTEMA. sa^osteme. LARGE, SUPPURATIVE INFLAMMATION IN A DEEP SEATED ORGAN ; PUS COPIOUS: AND CONFINED. The term apostema is Greek, from xf tempi, " discedo,'1 " abscedo," —whence the Latins employed abscessus, to express the same general 164 llttMATICA. [CL. IH.-OR. II. idea. Yet they did not, strictly speaking, apply either abscessus or apostema to every suppurative inflammation, but only to those that were deep-seated, and of considerable extent; chiefly indeed to collections of pus consequent upon fevers, or some previous disorder of particular parts, especially abdominal diseases. This limitation is accurately drawn by Celsus immediately after his description of struma, furimculus. and phyma. " Sed cum omnes hi nihil nisi minuti abscessus tint, generate nomen trahit latius vitium ad suppura- tionem spectans. Idque fere fit aut post febres, aut post ordoles partis alicujus, maximeque eos qui ventrem infestarunt." The term abscess however, which was colloquially used in a loose sense in the time of Celsus, is used so much more loosely in our own day, that it is impossible to recal it to its precise and original meaning. Yet apostema has not been thus generalized; and it is here, there- fore, laid hold of and restrained to the signification expressed in the generic definition ; after the authority, indeed, of Sauvages, who has employed it with the same limitation. the genus apostema in the arrangement before us will be found to include five species : the first of which is common to most fleshy parts, and possesses a common character ; while the remaining four are distinguished by some peculiarity of character, produced by a peculiarity of situation: 1. apostema commune. common aposteme. 2. ------<— psoaticum. psoas abscess. 3. -------- hepatis. abscess of the liver. 4.--------empyema. lodgment of matter in the CHEST. 5.-------: VOMICA.

INFLAMMATION COMMON TO THE FLESHY PARTS : PAIN OBTUSE : TUMOUR SPREADING EXTERNALLY : TENDER TO THE TOUCH : PUS LAUDABLE : READILY INCREASING WHEN OPENED. In whatever part an aposteme is seated, it will sometimes spread to a wonderful extent, and be loaded with a prodigious weight of pus M. Balme gives us an account of an abscess that extended through the whole parietes of the chest and abdomen on one side and reached from the scapula to the thigh ;* and Hildanus was present * Journal de Medicine, &c. Tom. xvn. GE. I.-SP. I.] SANGUINEOUS FUNCTION. 165 when, upon opening a patient after death, twelve pints of pus were found effused from a visceral aposteme into the cavity of the abdomen.* . In all such cases the first stage of inflammation, that ot adhesion, must have been overshot in the violence of the action, or from some other cause, and the suppurative and ulcerative have commenced simultaneously from the first. For otherwise the coagulable, or as Mr. Hunter prefers to call it, the coagulating lymph thrown forth, as has been already explained, into the cellular membrane in the earliest stage of the inflammation, would have formed a boundary wall by the production of new vessels and reticulations, much nearer to the salient point of the inflammatory action, and confined the secretion of pus to a much narrower limit. The secretion of coagulable lymph, and the reticulate adhesion and formation of new vessels which issue from it, is indeed designed, as has been explained already, to prevent the necessity of the suppurative and ulcerative stages of inflammation; and the natural cure of the adhesive stage is by resolution. When, therefore, an aposteme takes place in a healthy frame, or, in other words, when the inflammation passes into the two ensuing stages of the suppurative and ulcerative, and pus is formed, and a cavity scooped out for its reception, we are to take it for granted that the instinctive and remedial power of nature is incapable of producing a cure by the first intention; that some dead part or extrinsic substance is required to be removed, and that the two ensuing stages of inflammation are had recourse to for this purpose. In the formation, then, of an aposteme in a healthy constitution, we are to suppose that some part of the organ in which inflamma- tion occurs, as for example, a piece of the muscle of an arm or a leg, is become dead, and an incumbrance to the living parts that surround it, instead of assisting in their office. In effecting, there- fore, the important object of a cure, it is obvious that two distinct actions are necessary; the dead part must be carried off, and its part must be filled up by a substitute of new matter possessing the precise properties of the old. And in the process which takes place to accomplish these two purposes, we meet with another clear and striking instance of that wonderful instinctive power which pervades every portion, both of the animal and the vegetable world, and which is perpetually stimulating them to a repair of whatever evils they may encounter, by the most skilful and defi- nite methods. In order to comply with this double demand of carrying off the dead matter, and of providing a substitute of new, the absorbent and the secernent vessels in the living substance that immediately surrounds that which requires to be removed, commence equally, and nearly at the same time, a new mode and a new degree of action. A boundary line is first instinctively drawn between the * Cent. n. Obs. 57. 166 HjEMATICA. [CL. III.-OR. II. dead and useless, and the living and active parts; and the latter retract and separate themselves from the former, as though they had been skilfully divided by a knife. This process being com- pleted, the mouths of the surrounding absorbent vessels set to work with new and increased power, and imbibe and carry off whatever the material may be of which the dead part consists, whether tat, muscle, ligament, cartilage, or bone; the Whole is equally sucked up and taken away, and a hollow is produced where the dead substance existed. While this is proceeding, the mouths of the corresponding secer- nent vessels from the first, and perhaps somewhat antecedently, commence a similar increase and newness of action ; and, instead of the usual fluid, pour forth into the hollow a soft, bland, creamy, and inodorous material, which progressively fills up the cavity, presses gradually against the superincumbent skin, in the gentlest manner possible distends and attenuates it, and at length bursts it, and exposes the interior to the operation of the gases of the atmosphere. From this period the process of incarnation commences : granula- tions of new living matter pullulate on every side, assimilating themselves to the nature of the different substances that are lost, till the hollow is sufficiently filled up, and the organization completely regenerated. On the bursting of an abscess externally, we occasionally find that a portion of the dead matter still remains, which is, afterwards, gradually sloughed away, or is thrown off by a separation at its base. This is particularly the case in furuncles or boils; and still more strikingly so in large abscesses that include bones or the tendinous parts of muscles which are more difficult of absorption, though even these are sometimes absorbed, and completely carried off. The attenuation of the superincumbent integuments of an abscess appears to be produced by the stimulus of distension occasioned by the pressure of the accumulating pus. And it is to the same stimulus that Mr. Hunter resolves the absorption of the dead matter itself, conceiving that for this purpose the secretion of the pus commences somewhat earlier than the absorbent process. The formation of pus, and consequently the existence of an apos- teme, is evidenced by a cessation of the pain of distension, which gives way to a throbbing pain, synchronous with the dilation of the arteries ; and by irregular shiverings, and sometimes rigor. After a few days a weight is felt in the part, the throbbing pain itself subsides, the tumour becomes soft, and, if it point sufficiently towards the surface, fluctuates to the touch. There is some doubt to whom we are indebted for the first insight into this wonderful process; for it was taught at the same time, or nearly so, on the continent by De Haen, Plenciz, and Schreder, and in our own country by Hewson, Hunter, Home, Cruikshank, and Professor Morgan: but upon the whole, Mr. Hewson appears to have taken the lead, and the rest to have followed closely in his steps. Antecedently to which period, pus, instead of being a pecu- GE. I.-SP. I.] SANGUINEOUS FUNCTION. 167 liar secretion, was supposed to consist in a dissolution of the blood- vessels, nerves, muscles, and other solids, in the ordinary exhaling fluid when augmented by effusion ; or in a conversion of the serum, thrown forth on the occasion, into the new matter, by a change effected in its gluten during its state of stagnation : the first of which hypotheses was that of Boerhaave,* Platner,t and almost all who practised antecedently to their time ; and the second that of M. Gaber,J and Sir John Pringle.§ These conjectures were ingenious, but they were nothing more; and their errors are sufficiently pointed out in the ' Experimental Inquiries' of Mr. Hewsou, to whom physiology, and especially the science of morbid anatomy, is almost as much indebted as to any person whatever. He travelled with a comprehensive mind, and a zealous and indefatigable step, in what was at that time new and untried ground; and though he was mistaken in a few points, he correctly explored much, and, by the course he laid down, indicated to his successors the truest methods both of confirming his facts and correcting his misconceptions. He proved decidedly that pus is a peculiar secretion, and that it is often, indeed, secreted where there is no abscess or breach of surface : and he ingeniously accounted for its production by suppos- ing it to be formed out of the coagulable lymph by a new power given to the secernent vessels in consequence of the inflammatory action. " And if pus," says he, " in these cases, is produced merely by a secretion, so likewise it would seem probable, that even in abscesses, where there is a loss of substance, it is not the melting-down of the solids that gives rise to the pus, but the pus being secreted into the cellular membrane from its pressure, and from other causes, deadens the solids, and then dissolves\\ them." This idea of the solids contained in an abscess being deadened and dissolved by the pus which surrounds them, in the ordinary sense of the expression, (for in one sense, as will appear hereafter, they may be said to be dissolved,) was one of the erroneous opinions of Mr Hewson to which I have just alluded; and originated frpm too close an adherence to the earlier, and still more mistaken hypo- theses we have just noticed. And hence, with all his ingenuity, Mr. Hewson advanced not much more than halfway in explaining the entire economy of sup- purative inflammation. It remained for the exploring eye and commanding genius of Mr. Hunter to penetrate through a conside- rable portion of the remaining half of this curious process, and to prove that the solid parts contaiued in the are- of an abscess, in- * Aphor. 387. t Instit.

The greater part of this nice fabrication is rendered so clear in Mr. Hunter's admirable work on inflammation, and his arguments and his facts have been so fully confirmed, and so abundantly ex- emplified by later physiologists, and particularly by Mr. Cruikshank in his valuable treatise on the absorbents, as to remove every doubt upon the subject in the minds of the great body of the profession. And it is hence not a little surprising, that Dr. Cullen's Practice of Physic should be still printed and circulated, and more than this, be still employed as a text book (as I am told it is,) in many of the most celebrated schools of the present day, with the old, mistaken, and exploded hypothesis of the formation of pus out of secreted se- rum, advanced as a true and genuine doctrine,* without the slight- est hint of any newer or more satisfactory explanation of the sub- ject. It is still more surprising, that the same antiquated doctrine should be taught in the latest editions of Mr. B. Bell's valuable treatise on ulcers :j and most of all, (to the present author, at least, most of all,) that his friend Dr. Parr, with all the light of his con- temporaries before him, should have offered it as his own opinion, in his elaborate and upon the whole very excellent Medical Dic- tionary ; in which he tells us, after M. Gaber, that the pus of an ab- scess " consists of the substance of the vessels, and of the cellular mem- brane dissolved in the serum." That pus, instead of being a mere solution of dead animal mat- ter, is a distinct and peculiar secretion, is now known to most prac- titioners from personal observation ; who must have witnessed it repeatedly in situations in which there has been no ulceration or breach of structure, and consequently where there could be no dead animal matter to dissolve. It was noticed in this form by De Haen so far back as the mid- dle of last century; and was pointed out by Mr. Hewson as fre- quently found, on dissections, on the surface of the pleura, the pe- ritoneum, the pericardium, in a perfectly genuine state. A very decided case, to which both Dr. Hunter and Mr. J. Hunter were witnesses, was published by Mr. Samuel Sharp about the same time that De Haen first brought the subject before the public. No- thing is more common or more copious than the secretion of * Book n. Ch. i. Sect. gcl. + Part i. Sect. iii. GE. I.-SP.

Genuine pus is peculiarly distinguished by its consisting of white globules swimming in a fluid, which to the eye has the appearance of serum, but possesses characters of its own, equally different from those of serum and of every other secretion we are acquaint- ed with ; and which render it coagulable in a saturated solution of muriate of ammonia, which is its specific test. Pus, however, is not globular at its first formation, but a transparent fluid of a con- sistence in some sort resembling jelly ; the globules are produced while it lies on the surface of the sore, usually, when not exposed to external air, in about fifteen minutes after its secernment The perfection of pus seems to depend upon the large proportion which its globules bear to its other parts. It is specifically heavier than water, and approaches nearly to that of blood. It has a sweetish, mawkish taste, (apparently from its containing sugar,) very diffe- rent from that of most other secretions. After putrefaction it evinces an acid. Dr. Bruggmans, who has analysed it with much care, asserts that it has an acid also before putrefaction; but this has been deni- ed by Sir Everard Home * For a further account of its chemical properties, the reader may consult Dr. Pearson's elaborate paper on this subject in the Philosophical Transactions.! In the process of the natural cure of an aposteme, we find that the stage of granulation, and consequently of incarnation, immediately succeeds that of ulceration or the removal of the dead matter. " The vessels," says Mr. Hunter, " forming themselves into a cer- tain structure which fits them for secreting pus, it is so ordered that the same structure also fits them for producing granulations; and thus these two processes are concomitant effects of the same cause, which cause is a peculiar organization superadded to the vessels of the part."| The idea of a change of organization is hypothetical, but inge- nious, and perhaps correct.

The obvious design of granulation or incarnation, as it is often called, is that of repairing the loss the parts have sustained by the injury done : it is that of producing new flesh. Granulation, like vegetation, takes place from the centre below, in a direction up- wards toward the skin; and hence exactly contrary to the course of ulceration, which alway begins in the superior part of an ab- scess. The process commonly succeeds best upon exposure to the air, or at least after an opening externally; though there are in- stances of its having occurred where there has been no exposure whatever. The granulating pullulations, according to Mr. Hunter's explanation, consist of exudations of coagulating lymph from the vessels. He conceives it probable not only that the old vessels ex- tend into these pullulations and become elongated, but that new vessels also form in them, and, like the old, still continue to secrete pus. The granulations, as they become formed, mutually and readily unite; in osculation or the attraction of cohesion is estab- lished between them; and their vessels thus joined are transformed from secreting into circulating tubes. Immediately upon their for- mation, cicatrization seems to be in view. The parts which had receded, in consequence of a breach being made into them, begin now from their natural elasticity, and probably from muscular con- traction, to be brought together by the new-created substance ; and the contraction of the sore proves a sign that cicatrization is speedi- ly about to follow. This contraction takes place in every point, but principally from edge to edge, which brings the circumference of the sore towards the centre : so that the exposed surface becomes smaller and smaller, even before there is any formation of a new skin. There are two parts, at least, of this wonderful economy that still demand explanation. The first is the real use of the pus after it is secreted; and the second, the means by which the absorbents carry off the dead matter. The same explanation may perhaps apply to both. That pus is a peculiar secretion distinguished by peculiar pro- perties, and not a solution of the dead animal matter which it is the design of nature to remove, has already been sufficiently shown. " But I am apt to believe," says Mr. Hunter, " that we are not yet well, or perhaps not at all, acquainted with its use, for it is common to all sores; takes place in the most perfect degree in those sores which may be said to be the most healthy, and especially in those where the constitution is most healthy."* It forms, indeed, an exit to foreign bodies: is supposed by many to carry off humours from the constitution, or convert general into local complaints ; and by others to act as a preventive of numerous diseases. Yet all these services, even admitting them to exist, are but secondary, and the final intention still remains to be accounted for. * On Blood, &c. Part 11. Ch. v. p. 4S6. GE. I.-SP. I.] SANGUINEOUS FUNCTION. ]7l In like manner, since the dead matter of an aposteme does not constitute the pus that is found in it, and hence can only be carried off by absorption, we have yet also to learn by what means it be- comes prepared for an entrance into the delicate mouths of the absorbent vessels. There is no small difficulty in conceiving how these very minute mouths can apply themselves with sufficient ac- tivity to the various tough and hard substances they have to re- move, as tendon and bone, when in close contact with them ; but, as soon as the dead part becomes separated from the living, they are often no longer in close contact with them, except at the base, where there is little or no absorption at all; and in many cases, as in boils, carbuncles, and other imperfectly suppurating tumours, possessing cores or tenacious sloughs, are at a considerable distance from them, with the entire body of the contained pus placed inter- mediately in the hollow. In the last case it seems impossible for them to act except through the medium of the pus; in reality except through a solvent power possessed by the pus and exercised upon the matter to be removed. And if such be the nature of the action in this case, it is doubtless the nature of the action in all other cases: and hence we arrive at one immediate and direct use of pus, which is, that of becoming a solvent of the dead animal matter that requires to be carried off: not, indeed, by converting the whole substance at once into a fluid mass, and still less into a fluid mass of its own nature, as supposed by Sir John Pringle, but only the surface of the substance to which it is applied; and which hereby is rendered fit for absorption, carried forward to the mouths of the imbibing vessels, and absorbed ac- cordingly. And as the same power is exerted in succession upon every fresh surface of the dead matter that becomes exposed to its action, the whole is at length carried away, and a cavity produced where before was solid substance. That pus first kills and then dissolves the organized matter of an abscess was, as we have already seen, the opinion of Mr. Hewson. In the first part of this opinion he was completely mistaken; for, as we have already observed, the organized matter is dead before the process of suppuration even commences ; in the second, he seems to a certain extent to have been correct, though he still erred in supposing the dead substance to be melted down into its own na- ture, and was unacquainted with the important process of its ab- sorption. But in advancing his own full and more elaborate hy- pothesis against the mistakes of Mr. Hewson's, Mr. Hunter ran into the opposite extreme ; and contended, that pus is not designed to be a solvent at all, and that animal substances are decomposed in it with very great difficulty: thus leaving us totally at a loss to ac- count for its use ; and equally so to explain the manner in which the mouths of the absorbents of an abscess can operate upon or even, in many instances, get at the material they are to remove. Mr. Hunter, however, with the candour that so peculiarly be- longed to him, made this question a subject of experiment, and the 172 HyEMATlCA. [<*' '"--°R- «• experiment, as he conceived, fully established his Pre-conc^e^ opinion : and gave proof that the pus of an ab«e« doe« not act as a solvent. This conclusion of his only shows how dtfficatt it is tor the most honourable mind, when biassed by a favourite hypothesis to weigh with an even hand the evidence that lies before it I o see," s°ays he, « how far the idea was just that dead animal matter was dissolved'by pus, I put it to the trial of experiment be cause I could put a piece of dead animal matter of a given weight into an abscess, and which could at stated times be weighed. To make it still more satisfactory, a similar piece was put into water kept to nearly the same heat. They both lost in weight; but that in the abscess most. And there was a difference in the manner, for that in the water became soonest putrid."* There is nothing in animal chemistry, strictly so called, that decomposes animal substances so rapidly as putrefaction. And yet in the present instance the pus of an abscess evinced a more active decomposing power than the fluid of water, though aided by the accessions of putrefaction. It is not very wonderful that Mr. Hunter, though regarding this re- sult as in his favour, should not be disposed to " rely on its accura- cy," and he refers us, therefore, for a further proof to a more com- petent experiment of Mr. (now Sir Everard) Home, which consist- ed in immersing a portion of muscle weighing exactly one drachm, " in the matter of a compound fracture in the arm of a living man, and a similar portion into some of the same matter out of the body ; also a third portion into fluid calf 's-foot jelly, in which the animal substance was pure, having neither wine nor vegetables mixed with it. These portions of muscle were taken out every twenty- four hours, washed in water, weighed, and returned again." The result of this experiment is still more in favour of the sol- vent power of pus than the preceding. At the end of forty-eight hours there was indeed no great difference, as the muscle in the abscess was reduced to thirty-eight grains, and that in the other two fluids to thirty-six. But from this period to ninety-six hours the muscle in the jelly continued the same, while that in the ab- scess was reduced to twenty-five grains ; and that in the exposed pus dissolved ;t the power of putrefaction, as Mr. Hunter observes, being in this last case superadded to that of the pus itself. We hardly stand in need of other experiments. The solvent power of pus above that of water, of animal jelly, and hence we may conclude of animal fluids in general, is sufficiently established by the very evidence that is advanced in opposition to this power. And it should hence seem, that one at least of the direct uses of pus is to reduce, surface after surface, the dead animal matter which is exposed to its action, to that state in which it may be rendered fit for absorption, and at the same time conveyed to the mouths of the absorbent vessels. * On Blood, &c.

I.] SANGUINEOUS FUNCTION. 173 But I have for many years thought that it has also another equal- ly important use ; that, 1 mean, of assisting in the process of granu- lation ; and a late article of Sir Everard Home in the Philosophical Transactions, containing the observations of Mr. Bauer upon the germination of plants, and his application of those observations to the growth of the new vessels in animals,* seems, if not to have settled the question, at least to have very considerably favoured this view of it. . . Having sown a quantity of wheat for the purpose of noticing the changes which occurred from the first, Mr. Bauer took up every day several grains or plants for examination till they were ripe; and in the course of his attention, was much struck with the rapid increase, of the tubular hair of the root of a young plant of wheat in its earliest stage of vegetation; and, fixing his view entirely to that part of the plant, he observed small pustules of a slimy sub- stance arising under the epidermis in the surface of the young root; and in a few seconds a small bubble of gas bursting from the root into the slimy matter which it extended in a moment to the length the hair was to acquire; when the slimy matter surround- ing the gas immediately coagulated and formed a canal. He re- peated his observations on another plant, whose pubescence con- sisted of a1 jointed hair, and observed the same effect; a bubble issued from the young stalk, and extended the slimy mucus to a short distance, forming the first joint, which immediately coagulat- ed and became transparent; and at its extremity a new pustule of the same slimy matter accumulated, into which, in a short time, the gas from the first joint rushed : and thus, in a moment, a second joint was formed. In the same manner, he observed, the forma- tion of the hairs often or twelve joints take place. Impressed with the importance of these facts, Sir Everard Home immediately began to inquire how far the same course is pursued in the production of new animal matter. He first ascertained by experiments of Mr. Brande, already noticed in the proem to the second class of this work,! that blood in a state of circulation con- tains a considerable proportion of air, which, in the process of its coagulating, escapes in the form of carbonic acid gas, and in its escape produces bubbles as in the slime of plants ; and that it es- capes equally from the coagulating blood of veins and arteries, from effused serum and from pus. And in pursuing the subject he found that, on the coagulation of a drop of blood placed in the field of a microscope, an intestine motion occurred, and a disengage- ment of a something took place in different parts of the coagulum; beginning to show itself where the greatest number of globuies were collected, and from thence passing in every direction with considerable rapidity through the serum, but not at ail interfering with the globules themselves, which had all discharged their co- * Phil.

Wherever this extricated colouring matter was carried, a net-work immediately formed, anastomosing with itself on every side through every part of the coagulum. When the parts became dry, the appearance of a net-work remained unalter- ed. In some instances bubbles were seen to burst through the up- per surface of the coagulum; this however did not prevent the ramifications that have been described from taking place. " When this happens," continues sir Everard, " in living animal bodies, from whatever cause, and in whatever circumstances it takes place, no difficulty remains in accounting for its afterwards becoming vas- cular, since all that is necessary for this purpose is the red-blood being received into the channels of which this net-work is form- ed." He next proceeded to the subject immediately before us. " As the globules of pus," says he, " are similar to those of blood, I made experiments upon the fluid in which they are suspended, and found inspissation produce the same effect on it as coagulation does on the other; that a similar net-work is formed and apparent- ly by the same means, since if pus be deprived of its carbonic acid gas, (of which it contains a large quantity,) by exhaustion in the air-pump, no such net-work takes place." Additional experiments are still necessary upon this interesting subject; but so far as they go, they seem very clearly to indicate the important and double use to which pus is subservient; that it acts as a solvent upon the dead matter, preparing it for absorption, and as a fomes for granulation and the production of new vessels. Nor let it be observed in opposition to this conclusion that we are thus endowing it with incongruous and contrary qualities ; and that if it be erosive in the one instance it cannot be nutrient in the other; for the animal economy presents us with various examples of like effects, contrary indeed but not contradictory, produced by one and the same secretion on dead and on living matter, for which we need go no further than to the very common operation of the gas- tric juice ; which, while the most powerful solvent of dead animal matter in the whole range of animal chemistry, is a healthy stimu- lant to the living stomach, and even to other living organs; and has successfully been applied externally for this purpose by surgeons, to weak and ill-conditioned ulcers, and employed by physicians as an in- ternal tonic in cases of dyspepsy and cardialgia.

PAIN AND TENSION ABOUT THE LOINS, SHOOTING DOWN THE SPINE AND THIGHS ; DIFFICULTY OF STANDING ERECT ; FLUCTUATING ENLARGEMENT ALONG THE PSOAS MUSCLE; APEX OF THE TUMOUR IMMEDIATELY BE- LOW THE GROIN. This is one of the most lamentable diseases we can ever be called upon to attend. It commences insidiously, and at the same time in parts so deeply seated as to render it very difficult to determine the place of its origin; and hence the psoas muscle itself, the cellular substance interposed between the peritoneum and the loins, the lym- phatic glands near the receptaculum chyli, and the lumbal verte- brae have been pitched upon by different writers. It is probable that most of these have formed the primary seat of affection in dif- ferent cases, and that the inflammation has subsequently spread to one or more of the other parts. The pain at first is by no means violent, and the patient thinks lightly of it; it is sometimes felt in the back rather lower than the region of the kidneys ; and sometimes as low down as the thigh. From the deceptive manner of its at- tack, medical advice, and particularly a free use of purgatives and the lancet, which might have been of essential service at first, is fa- tally postponed; and the symptoms are regarded as those of an ac- cidental strain. After the abscess is formed, however, the pain, in most cases, increases considerably ; and the matter may be discharg- ed into the cavity of the abdomen, where it would soon be fatal. On this account it obeys the law of instinct we had lately occasion to notice ; follows, in most instances, the course of the psoas muscle, and points externally a little lower than the inguinal glands; or it passes down the thigh, where, however, it is apt to dissever the muscles and form sinuous abscesses. Sometimes, though rarely, the matter passes through the muscles of the back, and is discharged in the loins ; and in a few instances it has been known to fall into the cavity of the back part of the pelvis. The abscess, therefore, is highly dangerous; since under the most fortunate circumstances it is so long in pointing externally, even if it should make any visible pointing at all, that the patient usually sinks under a hectic fever, produced by the local irritation. While in most cases, in which it has made a natural opening for itself, it has been found connected with so many deep sinuses, which cannot be followed up, that the same effect ensues. No mode of medical treatment has been found productive of any good purpose ; and the case has been, in a very early stage of the 176 H^MATICA. [ex. m.-oR. n. suppuration, given over to the surgical practitioner. Yet even here different individuals have pursued different lines of conduct. Mr. Bell advises an early evacuation of the matter, lest the bones should become injured; while Mr. Abernethy apprehends less danger from its being suffered to remain, and at last evacuates it at different in- tervals, and by successive operations: by which means the cyst, in which the pus is principally lodged, may have an opportunity of contracting; and this, he thinks, it has a greater tendency to do than in abscesses where the inflammation is more violent. He is also attentive to close the opening the instant the matter is dis- charged, so as to prevent any increase of the inflammation by an access of air. The real cause of danger does not seem to have been hitherto hit upon; but it may probably be referred to that tendency to a ra- pid spread of inflammation over their entire surface, which Mr. Hunter has shown to exist in all internal cavities, and the hazard of which is in proportion to the extent of the cavity; a subject alrea- dy touched upon in the discussion of puerperal fever, and which we shall have other opportunities of illustrating as we proceed, parti- cularly in some cases of varicose enlargement of the veins. Now in the disease before us we have not, it is true, any natural cavity, but we have an artificial cavity of long standing, and large extent, in a highly irritable state, and which is therefore peculiarly predis- posed to run into all the fatal effects of large natural cavities, when injured or otherwise rendered imperfect. The author throws out this hint, however, for future and general consideration. SPECIES III. APOSTEMA HEPATIS. ^iiiscfss of the Sifter. DIFFUSE PULSATING TUMOUR IN THE REGION OF THE LIVER ; PRECEDEB BY PAIN, A YELLOW COUNTENANCE AND SHIVERING. This is also a very fatal disease; and usually terminates in one of the following ways: Firstly, The substance of the liver is gradually and almost entire- ly absorbed from long continued irritation : the melancholy accom- paniments of which are a tedious icterical marasmus, hectic fever, great anxiety, and a sanious and fetid diarrhoea, which is the fore- runner of death. Secondlyy The abscess breaks internally and discharges a sanious pus into the belly; by which means the rest of the viscera are af- fected ; and the termination is marasmus, acites, and dissolution. GX. I.-SP. III.] SANGUINEOUS FUNCTION. 177 Thirdly, The pus sometimes finds a passage into the biliary ducts, and thence into the intestines; from these it is occasionally thrown into the stomach and vomited in the form of a dark offensive mate- rial : but far more generally it is carried downward and produces a violent looseness. Acids and acescent medicines may here palliate for a time ; but the issue is always fatal. Fourthly, The enlarged liver becomes, in some cases, united by adhesive inflammation to the peritoneum, and the abscess opens ex- ternally ; and, in this case, there is a chance of cure. The opening should be expedited by a caustic, or the knife ; and the cure will greatly depend upon the nature of the fluid which is discharged. Fifthly, There is reason to believe, that in a few rare instances the matter is carried off by absorption, when a healthy granulation takes place, and a cure is completed without any opening. This termination is more reasonably to be expected in a constitution otherwise sound, and where the liver has not been weakened or ren- dered torpid by any former affection. It is hence rather to be look- ed for in a temperate than in a tropical climate, and in youth than in advanced life. These cases may, indeed be regarded as sequels of hepatitis ; though it is possible that pus may be thrown into the penicilli and biliary pores of the liver by a metastasis from some other organ, as it not unfrequently is into the tubules of the kidneys, and thence conveyed to the bladder. When the cure takes place without an opening, it is not always an easy matter to determine for a certain- ty that pus has actually been formed. But sometimes we can trace a fluctuation; and at other times the subsidence of the tension, pain, and pulse, after one or two severe shivering fits, may be re- garded as sufficient indications. In a case of this kind that occurred to me in a young gentleman of about thirteen years of age, the shi- vering was so considerable as to make the teeth chatter; and with- in eight-and-forty hours the pulse sunk from a hundred-and-forty to a hundred-and-twenty; and the abdominal tension and tenderness were considerably abated; as was also the distressing cough with which he had almost perpetually been harrassed for some weeks. He was put upon a tonic plan of columbo and sulphuric acid imme- diately after this change, and recovered gradually. VOL. II 23 178 H&MATICA. [CL. HI.-OR. II- SPECIES IV.

To the symptoms enumerated in the above definition Hippocrates adds,* edema of the feet, hollowness of the eyes, and a gurgling sound on shaking the shoulder. Of these additional signs, the hrst two belong rather to the hectic fever that generally accompanies empyema, than to the disease itself. The last has sometimes been met with in modern times.t Dr. Cullen regards empyema as a mere sequel of pneumonia, which with him includes inflammation ot the pleura, as well as of the lungs, but as it may take place from in- flammation of the mediastinum, pericardium, or diaphragm, to say nothing of that from external injuries, and as it is often doubtful what particular organ is directly injured, a separate species seems decidedly called for. Goekel, indeed, describes a case in which the pericardium was affected in connexion with the right lung, and to such an extent that both were totally consumed. In some instances, there is no organ to which the pus can be re- ferred as a process of ulceration; and to such an affection Mr. Hewson has several references. " The cavities of the pleura, pe- ricardium, &c." says he, " are sometimes observed to contain con- siderable quantities of pus without the least marks of ulceration. In one patient I found three pints of pure pus in the pericardium without any ulcer either on that membrane or on the heart. In another the cavity of the pleura of the right side was distended with a pus that smelt more like whey than a putrid fluid, and the lungs were compressed into a very small compass: but there was no appearance of ulcer or erosion either on these organs or on the pleura; but only under the pus was a thin crust of coagulable lymph." We have already observed upon this secretion of imper- fect pus, and it is not necessary to explain it any farther: Dr. Darwin relates a singular case of empyema, in which the pus seems in like manner to have been produced without ulceration, though he ascribes it indirectly to an abscess in the lungs. " A ser- vant man after a violent peripneumony, was seized with symptoms of empyema, and it was determined, after some time, to perform the operation; this was explained to him; and the usual means * Ilt/x n*6»v, p. 476, 496. t Trecourt Memoires de Chfcugie, &c.

By which good advice he conceived so much fear that he ran away early next morning, and returned in about a week quite well." This should indicate that something may at times be accomplish- ed by internal medicines, though no plan has hitherto succeeded that has been devised by professional skill. Nor is the present the only case on record in which the contain- ed fluid has disappeared by metastasis. It has passed off by the in- testinal canal,* by the bladder,! and by the vagina,! in the form of pus ; and is said in one instance to have vanished on the eruption of a scabies.§ It has also frequently passed off, by an opening formed by nature, and the patient has recovered his usual health. This opening has commonly been between the ribs, most usually between the third and fourth, but in one instance we find the abscess point- ing and bursting under the scapula.|| Morgagni has recorded a sin- gular case of a double empyema, a lodgement of pus being formed on both sides.TT And Balme a still more extraordinary case, in which the pus entered the cellular membrane and spread over almost the whole trunk.** When the fluid is discharged by paracentesis, Hippocrates urges repeatedly upon the surgeon to evacuate it only by degrees ;TT and Borelli gives a case in which the patient seems to have sunk and been lost under a sudden evacuation alone.ft There has also been no small discussion concerning the part of the thorax to which the scalpel may be most advantageously applied. David, in his prize dissertation, advises near the sternum ;§§ Mr. Sharp between the sixth and seventh rib;|||| Mr. Bell wherever the pain or fluctuation may directlFIT Mr. Warner, whose success made it many years ago a favourite operation in our own country, seems to have been of Mr. Bell's opin- ion, and varied the point of opening according to the nature of the case.

In Mr. Warner's cases, about twenty ounces of pus formed the average of discharge at the time of the perforation :* the patients usually found instant relief; the pain, cough, and quickness of pulse diminishing, and the breathing becoming easier. He dressed the wound with a sponge-tent till there was no longer any discharge, and afterwards superficially; and in about six weeks the patients were discharged cured. In this case it is perhaps more necessary to keep the wound open than in any other operation, since, till the ulcerated surface of the interior is completely healed, the secreted pus is apt to accumulate, and the operation must be renewed. Tents of all kinds are very properly exploded in most cases in the present day; but Mr. Bell has judiciously observed that in the para- centesis the old fashioned practice ought still to prevail.t Dr. G. Hawthorn has given an instance of this disease, that for its severity and danger, and particularly for its successful issue, is well worth recording.^ The patient was thirty years of age, and the disease had been brought on by exposure to damp night-air, in a state of intoxication. He suffered greatly from quickness of pulse, incessant cough, oppression, and dread of suffocation. A distinct fluctuation was perceived in about three weeks from the attack; shortly after which he was a little relieved by a discharge of puru- lent matter effused into the bronchial cells, and expectorated to the extraordinary amount of five or six pounds daily, for many days in succession, a fluid of an intolerably offensive smell, and putrid ap- pearance. He continued, however, to grow worse and weaker; his feet and legs swelled; his countenance was ghastly and he had colliquative sweats. About twelve weeks from the attack the ope- ration was performed, nearly twenty pounds of pus were discharged on the first day and night; and he gradually recovered. Riedlin operated with success twice on the same person.S The matter when discharged or examined on dissection has been found, as may be easily supposed, of very different consistences; some- times pure pus, sometimes cheesy, and sometimes gelatinous. And the mischief to the interior of the chest has in some cases been very great. Several of the ribs have been found carious ;|| the lung on * See Phil. Trans. Vol. xlvii. xlvih.

DERANGED FUNCTION OF A THORACIC OR ABDOMINAL ORGAN ; SUCCEEDED. BY A COPIOUS DISCHARGE OF PUS INTO SOME PART OF THE ALIMEN- TARY CHANNEL ; AND ITS EVACUATION BY THE MOUTH OR ANUS. The specific term is a derivative from the Latin vomo, " to eject," especially from the stomach, but not exclusively so; and hence, on the present occasion, it i? used in the comprehensive sense in which it is employed by Celsus, who applies it to a bursting of pus from the liver, or any other large internal organ, as well as the lungs.} Sauvages follows Celsus in this interpretation Boerhaave and Cul- len confine vomica to the lungs, and this in a more restrained sense than most writers; for they limit it to what has been called, though with no great accuracy occult vomica, " vomica? clausae." Linneus and Vogel, on the contrary, while they confine the term to the lungs, explain it by open vomicos " vomicae apertae," in which the pus is thrown forth profusely and suddenly. One termination of the hepatic aposteme may be regarded as a variety of this species, for, as we have observed, it sometimes issues in a discharge of pus by the mouth or rectum. Wherever it occurs, it appears to consist in a conglobate gland, first enlarged by a strumous congestion, and afterwards slowly and often imperfectly suppurating. Vomicae vary in size, from the diameter of a millet-seed, to that of an orange. The smallest rarely contain any fluid, and sometimes not even a cavity; but they are often highly irritable, and maintain a very con- siderable degree of hectic fever. When ulceration has taken place, and pus is secreted, the irritability frequently subsides; the pulse improves, the febrile exacerbations are less frequent and violent, and the patient flatters himself he is recovering. The vomica at length bursts and disabuses him ; he sinks gradually from the quan- tity of the daily discharge, and the confirmed hectic ; or, if the dis- ease be seated in the lungs, and the cavity extensive, he may be suffocated by the volume of pus that overwhelms the trachea. * Kelner, Diss, de Empyemate.

The term phlegmon, from hvx.rxtmi, or vesicles, as the peculiar cha- racter of the eruption.

Where the skin is slightly broken, and the acrid fluid oozes through the minute openings, the vesications should be frequently dusted, as already recommended under the second species, with chalk, or starch; or, where the latter is too harsh and drying, with a mixture of equal parts of starch and finely levigated calamine ; carefully abstaining from all oleaginous or other applications that have a tendency to augment the relaxed state of the fibres.

This species offers us the two following varieties: x Simplex. The cuticle remaining unbroken. Simple Chilblain. /3 Exulceratus. Accompanied with ulceration. Kibe. The extremities principally affected by the chilblain are the hands and feet; but in very cold climates the nose, ears, and lips are affected also, and the living power is destroyed as completely as by combustion. So correctly has our great epic poet described the power of severe frost: The parching air Burns frore, and cold performs th' effect of fire. That the pernio or chilblain belongs to the genus erythema is perfectly obvious, not only from its symptoms, but from the character of the age and constitution in which it is chiefly to be met with, and from the stimulant mode of treatment by which alone it is to be cured. The proximate cause of chilblains is a diminution of the excita- bility or vital energy of the extreme vessels; and as such diminu- tion is most readily produced in children, or older persons of relaxed fibres, these are most subject to the disease. For though we often meet with it also in strong and hardy boys, it will usually be found that the last, from the natural vigour and courage of their frames, have braved the cold and rigid reign of the winter-season beyond the venture of their school-fellows. Local stimulants then are the only applications that will answer • and particularly those which serve at the same time to defend the weakened organ from the severity of the external air. Hence GE.

For the same reason embrocations of spirits of turpentine, opodeldoc, liquor ammoniae acetatis, or equal parts of vinegar and spirits of wine, will usually be found serviceable. Linneus recommends bathing the part with diluted muriatic acid, and this has the advantage of being astringent as well as stimulant. The weakened vessels should never be too much distended, and hence, though gentle warmth and stimulants are indispensable, great heat, and especially a near approach to a fire, and more particularly still when very cold, will always be found injurious. When the inflammation becomes ulce- rated, or forms a kibe, warm and irritant dressings will alone suc- ceed in effecting a cure ; and, if fungous granulations should appear, which they are very apt to do in all sores accompanied with debi- lity, they must be removed by a dressing of the unguentum hydrar- gyri nitratum, or some other mild escarotic.

The fret or erosion which frequently takes place in different part? of the skin from an acrid secretion of the exhalents or sebaceous glands, and particularly behind the ears, about the groins, and around the anus, is usually accompanied with erythematic redness, or inflam- matory blush; and is hence generally, and correctly referred to the present place. It is an erythema with weak vascular action, and often considerable irritability in consequence of such weakness. The most common example of this species is that which takes place behind the ears of children of a delicate habit, or who labour under irritation from teething, or from gross indulgence in luxuries. The discharge is often peculiarly offensive, and hence cannot pro- ceed merely from defective absorption, for it would then be nothing more than saline without fetor. It cannot be checked too soon; for if it continue for a few weeks, or perhaps even less, it may acquire a habit, the suppression of which may run the risk of super- inducing some worse disease than itself, as dyspepsy, diarrhoea, or convulsions. The organ affected should be kept well washed to prevent the spread of the morbid secretion, the discharge should be imbibed by dry and scorched rags applied to the part, or starch frequently dusted over it. But the irritability is here best suhdueil 212 HiEMATICA. [CL. III.-OR.

Sffsceeal Knttammatfon DERANGED FUNCTION OF A VISCERAL ORGAN, MEMBRANOUS OR PARENCHY- MATOUS ; WITH LOCAL PAIN; FEVER MOSTLY A CAUMA; INFLAMMATION MOSTLY ADHESIVE. The genus of diseases upon which we now enter consists of that numerous collection of visceral inflammations which, from the time of Boerhaave, have been generally distinguished by anatomical terms derived from the organ affected, with the Greek term itis added as a suffix, as cephalitis, gastritis, carditis and many others. Itis is sufficiently significant of its purpose : it is immediately derived from ttpai, which is itself a ramification from tu, and imports, not merely action, " putting or going forth," which is the strict and simple meaning of w, but action in its fullest urgency, " violent or impetuous action." As a suffix, therefore, we shall retain it in its common use, and proscribe it, to prevent confusion, from the few compounds, or proscribe the compounds themselves, in which this common use is departed from ; as rachitis, hydro- rachitis, ascites, and tympanites, none of which convey any idea of violent or impetuous action, and some of which are peculiarly marked by a contrary state. This application of a common term in composition to so large a body of visceral inflammations, and the general use of the term for so long a period as that throughout which it has been employed, is a sufficient proof that practitioners have discovered between these inflammations other features of resemblance than the general symptoms of inflammatory disorder. In the prosecution of the subject, we shall find that this is the fact; and I have already observed, towards the commencement of the present order, that, with a very few exceptions, the inflammation in all the diseases is of the adhesive kind, and the fever a cauma. With a view, therefore, of simplifying, as far as simplicity may be of real use, the present system will, for the first time, comprize the whole of these under one genus, here distinguished by the name ofEMp^ESMA, or " internal inflammation," a term, in its simple form, employed both by Hippocrates and Galen ; and which it seems necessary to revive for the present purpose. GE. VII.] SANGUINEOUS FUNCTION. 213 Many of the organs included under the genus before us, and which we shall presently follow up in their respective order, sympathize with each other, and most of them with the stomach. The necessary consequence of which is, that the constitution is disturbed generally, though in very different degrees according to the organ affected; or, in Mr. Hunter's opinion, according to the different degree of its connexion with tfie stomach. If the heart, the lungs, or the brain be inflamed, whether prima- rily or secondarily, as by sympathy, the stomach is peculiarly influenced, probably from the essential importance of these organs to the life itself (as all the vital organs, or those essential to the life, maintain a very close degree of affinity ;) and the disease, originating in any of these, has, in consequence, a more violent effect upon the constitution than the same quantity of inflammation would have if it were not in a vital part, or in one with which the vital parts do not sympathize. The pulse, in such eases, is much quicker and smaller than when inflammation takes place in a com- mon part, as a muscle, cellular membrane, or the skin. The progress, moreover, when the attack is so violent as to prove fatal, is, Generally speaking, far more rapid than in other parts; so that, at Us very beginning, it ha* the same effect upon the constitution a* a farther advance of an inflammation in other organs that is equally sure of proving fatal in its result. The debility commences early, because the inflammation itself is immediately interfering with actions essential to the life ; and, as already observed, the sympathy between these organs is peculiarly close, insomuch so as almost to make any single action common to the whole* In inflammation of the brain the pulse varies, perhaps, more than in inflammation in any other part; and we must rather depend upon other symptoms than upon the state of the pulse. It is some- times quick, sometimes slow, sometimes depressed, sometimes full, according as the disease is characterized by acute pain, delirium, stupor, or other concomitants. When inflammation is seated in the heart its action becomes extremely agitated and irregular. When in the lungs, the heart, possibly from sympathy, does not seem to allow of a free diastole. If the stomach be inflamed, the patient feels an oppression and dejection through all the stages of the disease. The vital energy, or simple animal life, seems to be impaired and lessened, in the same manner as sensation is lessened when the brain is injured. The pulse is generally low and quick ; the pain obtuse, but urgent and overwhelming; so that the patient can hardly bear up under it. If the intestines be affected, the symptoms are nearly of the same kind, especially if the inflammation be in the upper part of the canal; but if it be seated in the colon, the patient is more roused, and the pulse is fuller than when the stomach itself is inflamed. If the uterus be the organ attacked, the pulse is extremely quick * Hunter on Blood, &c. p. 325. 214 HjEMATICA. [cl. ih.-or. II. and low: if one of the testicles, the pain is depressing, and the pulse quick without much strength. With the uterus, the testicles, and the intestines the stomach peculiarly sympathizes ; often, indeed, as much as if itself were primarily affected. If we contrast these species of inflammations with those that attack parts not very es- sential to life, but with such a degree of violence as to produce uni- versal sympathy and affect the vital functions, we shall find that in the latter the pulse is fuller and stronger than common; and the blood is pushed further into the extreme arteries. The attack usu- ally commences with rigor; the patient then becomes somewhat roused because the action of the part is roused, and the effects on the constitution are not as yet such as to impede the operations of the vital organs. Much, however, will still depend upon the na- ture of the parts, whether active as muscles, or inactive as tendons; as also upon the situation of the same description of part, and espe- cially upon the character of the constitution : for if the last be ex- tremely irritable and weak, as in many women who lead sedentary lives, the pulse may be as quick, hard, and small, even at the com- mencement of the inflammation, as in inflammation of the vital parts. The blood, moreover, may be sizy, but will be loose and flat on the surface. Having premised these general remarks, we are the better pre- pared for examining the relations which the numerous species be- longing to the present genus bear to each other; and satisfy our- selves with a more summary account of several of them than would otherwise be necessary. SPECIES I. EMPRESMA CEPHALITIS. XnttamwattoH ot tfie iSratu. PAIN IN THE HEAD ; AVERSION TO LIGHT ; FACE MORE OR LESS FLUSHED J CAUMA. The pathology of cephalitis, or inflammation of the brain, is, in some degree, obscure and difficult, from the difference which occurs in several of its secondary or concomitant symptoms; occasioned partly, perhaps by the difference of its exciting cause, partly by the particular portion of the organ that is primarily or chiefly affected, and partly by circumstances which seem to baffle all research. Fiom this occasional difference of symptoms some nosologists have endeavoured to establish as many distinct affections, and have hence multiplied a single specific disease into a considerable number of distinct species, and even genera, and treated of it under a fearful GE. VII.-SP. I.] SANGUINEOUS FUNCTION. 215 host of distinct names : and hence the disease before us has been described, not only under the term cephalitis, but under those of phrenitis, paraphrenitis, phrenismus, sideratio, siriasis, sphacelis- mus, and typhomania, calentura, and a great many others, which have burthened the medical vocabulary, and perplexed the medical student. The disease may commence in the meninges, or membranes of the brain, or in the substance or parenchyma of this organ; and if it were to confine itself strictly to the part first affected, instead of spreading from one part to another, there would perhaps be no great difficulty in determining, from the symptoms before us, its di- rect and actual seat: for while membranous and muscular inflamma- tion, before the access of gangrene, is accompanied with an acute and rousing pain, great heat, and a pulse considerably and perma- nently quickened, parenchymatous inflammation is rather distin- guished by a heavy, and often a stupefying, pain, a slight increase of heat, and a pulse irregularly quickened sometimes sinking even below its natural standard.* Now both these conditions are occasionally found in different cases of cephalitis ; and we may hence infer that in the one in- stance the disease is seated chiefly, if not altogether, in the menin- ges, and in the other in some part of the substance of the brain it- self, thus presenting to us the two following varieties :— x Meningica. Pain in the head acute ; intolerance Phrenzy. of light and sound ; cheeks perma- Brain-fever. nently flushed; eyes red ; watch- fulness ; delirium; pulse rapid. C Profunda. Pain in the head obtuse ; cheeks ir- Deep-seated inflammation of regularly flushed ; pulse irregu- the Brain ; larly frequent; eyes oblique ; Acute Dropsy of the Head. sleep heavy but unquiet, and oc- casionally interrupted by screams. Chiefly common to children. The above clear and distinctive marks, however, by which the two varieties are separated from each other in exact cases are not often to be met with; as each, for reasons already given, is apt to assume something of the character of the other. And hence they have hitherto escaped the attention of all our nosologists, even of those who have subdivided inflammation of'the brain into the great- est number of distinct genera or species of disease; whilst Vogel expressly declares that all the most acknowledged symptoms of in- flammation of the brain are equivocal, not only as to a distinction of one morbid part from another, but as indicative of inflammation in any part; and Dr. Cullen asserts in a note subjoined to his generic definition (for he advances the disease to the rank of a genus, and Hunter, On Blood, &c. p. 288, 289. 216 HJEMATICA. [CL. III.-OR. II. a genus too without a species or a specific character,) that there are no symptoms capable at all times of distinguishing, with certain- ty, inflammation of the brain from inflammation of its meninges. On which account he deviates from the more complicated arrange- ments of Sauvages, Linneus and Sagar, and includes several of their genera in his own definition, which runs in more general terms as follows: " pyrexy severe ; pain of the head; redness of the face and eyes ;• intolerance of light and sound ; watchfulness ; fierce de- lirium or typhomania." There is so much correctness in this remark of Dr. Cullen's, not- withstanding the error of his arrangement, that the present author yielded to it in the first edition of his Nosology, and introduced cephalitis, not indeed as a naked genus without a specific character, but as a single species without enucleating its varieties ; or, in other words, without treating of deep-seated inflammation, constituting acute internal dropsy of the brain, separately from inflammation of the head generally. It may, perhaps, be doubted, whether acute dropsy of the brain ought to be regarded as an idiopathic inflamma- tion at all, and consequently whether the present is the proper place for it: but the reasons which will immediately be advanced will, I trust, settle this point completely. And, as, upon a closer attention to the subject, notwithstanding Dr. Cullen's remark, I am induced to think that there are cases in which parenchymatous or deep-seat- ed inflammation may be distinguished from meningic, 1 have so far deviated from the first arrangement as to give these distinctions un- der the form of the two preceding varieties. I admit, nevertheless, with Dr. Cullen, that there are no symp- toms capable at all times of distinguishing, with certainty, inflamma- tion of the substance of the brain from inflammation of its meninges ; and only contend that the distinction may be drawn in certain cases in which the disease is simple, and the characters strong and un- mixed ; and strikingly indicative of membraneous or parenchyma- tous inflammation, according to the general rules just laid down up- on this subject. I believe this simplicity of appearance is more frequently to be traced in meningic than in profound or parenchymatous cephalitis: or in other words, that in primary inflammation of the substance of the brain, the meninges are more disposed to partake of the affec- tion either by continuous action or sympathy, than the substance of the brain is in primary inflammation of the meninges. And hence those nosologists that describe but a single species, or genus of this disease, as it has been often though incorrectly denominated, as Vo- gei, Cullen, and Parr, lean chiefly to the meningic variety, and de- fine it by characters of great vehemence or acuteness, so as in reali- ty to limit themselves to this variety alone. Yet as the symptoms do not always nor even most frequently mount up to this aggrava- tion, in consequence of the disease more commonly originating, or being more ommonly se:)tfd, in the s-ibsmnce of the brain itself than in its membranes, they have all been dissatisfied with their respec- GE. V1I.-SP. I.] SANGUINEOUS FUNCTION. 217 tive definitions ; and instead of enlarging or modifying their terms to meet the distinctive phaenomena as they vary according to the seat of the disease, have endeavoured to apologize for their own inaccuracy, by representing these phaenomena as irreducible and ano- malous. The first variety, therefore, exists in the judgment, and even in the description of all writers, who, where they have not entered into more minute subdivisions, have given it as the general charac- ter of the complaint. The existence of the second variety, or in other words, the pro- priety of regarding what has hitherto been douominated acute or internal hydrocephalus as*a variety of cephalitis, requires to heexa- mined somewhat more at length. , The absurdity of the usual arrangement of internal hydrocepha- lus, and of contemplating it as belonging to the ordinary family of dropsies with which it has scarcely a common symptom, has long been felt by pathologists, and is directly noticed both by Sauvages and Cullen. But the question is, if we remove it from its usual si- tuation, where are we to place it? if we do not regard it as a drop- sy, in what light are we to contemplate it at all ? and how are. we to regulate our treatment of it? The professor of Montpellier tells us that, according to its symptoms, it is to be ranked in the coma- tose, spasmodic, or some other tribe of diseases : distinctly import- ing that, in his own opinion, he could not refer it to any single divi- sion in his very extensive classification. Dr. Cullen's reply is, that it is an evident and idiopathic species of apoplexy, and ought to take its place under that genus; and he has hence distinguished it by the appellation apoplexia hydrocephalica, and in this manner assigned it " a local habitation and a name." In reference to this assignment he observes, however, that, in a nosological work, it is difficult to collate exactly diseases that in their progress assume a changeable form, and hence to allot a perfectly fitting place to hy- drocephalic apoplexy. Yet I prefer, says he, placing this disease under the head of apoplexy, to placing it under that of hydrocepha- lus (dropsy of the head ;) first, as it differs extremely from the symptoms of sensible (external) dropsy of the head ; and next, as in its proximate cause, and at length in its symptoms, it bears to apo- plexy as near a relation as possible. Dr. Cullen evidently regarded the effusion or dropsy in the ven- tricles of the brain as a mere effect of the disease, rather than as the disease itself: yet the drowsiness, or heavy sleep, or whatever else there is a-kin to apoplexy, and which he contemplated as the proximate cause of the disease, and consequently as the disease it- self, is a still more remote effect than even the effusion, for it is pro- bably the mere result of such effusion. In truth, it is only necessa- ry to run over Dr. Cullen's specific definition of this disease, to see how very little it has in common with apoplexy. This definition is as follows: " apoplexy arising gradually ; affecting infants, and the age befow puberty, first with lassitude, feverishness, (febriculd,) vo». u. 28 218 HJEMATICA. [CL. IH.-OR. II. and pain of the head; afterwards with a slower pulse, dilatation of the pupil, and somnolency." The definition includes two stages of disease, if not two distinct diseases, a primary and secondary : and it is only in the second stage or secondary disease, the mere result of the first, that it bears any analogy to apoplexy. The first and leading symptoms are evidently those of pyrexy, which is therefore the fundamental part of the disease ; and had not Dr. Cullen been in some degree influenced by system, he would probably have coloured these symptoms a little more highly, as he might have done without any departure from the truth. And hence, while Dr. Parr, Dr. Young, and a few others, have adhered to Dr. Cullen's view of the subject, the gteat body of pathologists have been dissatisfied with it, and have correctly carried internal hydrocephalus over to the class of pyrexies, and regarded it as a fever or an inflammation. Thus in Dr. Macbride's table it occurs as a nervous fever, under the title of febris continua, nervosa, hy- drocephalic;! : and more simply under that of febris hydrocephalica, in Professor Daniel's edition of Sauvages; whilst Dr. Quin of Dub- lin, Dr. Withering, Dr. Rush, Professor Martini, and a host of other writers of authority, have contemplated and treated it as an inflam- mation,—an inflammation of the hrain,—and consequently a cepha- litis ; the fever being regarded as a mild and somewhat irregular cauma, and the effusion into the ventricles of the brain as a mere effect of the inflammation. This is not the only instance, indeed, in which cauma assumes a mild character. In various other species of empresma it is often found to do the same, of which the reader will find an interesting example under the species laryngitis, a few pages further on: and of which every practitioner is meeting with daily instances in pneu- monitis, and especially in inflammation of the parenchyma of the lungs producing suppuration. The general organ of the brain, however, seems to have less irritability than almost every other or- gan when in a state of health, and we often find it to be little irrita- ble in a state of lesion ; since nothing is more common than for a bul- let, or th,«■ broken point of a knife, sword, or other weapon, to be forcibly driven into it, and buried there for weeks, months, or years * in one instance eleven years,! not only without danger, but some- times with little inconvenience. In the third number of the Medico-Chirurgical Journal, there is an excellent paper upon the subject before us, by Dr. Porter of Bristol, which commences with a very correct pathological view of the disease^ minutely coinciding with the present arrangement and confirming this view by a variety of strongly marked and well se- lected cases. And I am glad to avail myself of Dr. Porter's authori- ty in following up this second variety of cephalitis, into a distinct and extended illustration. * Gooch's Cases. Hoe°s. Diss.Obseiv.

I.] SANGUINEOUS FUNCTION. 219 In few words both varieties not only evince symptoms of inflam- mation during the progress of the disease, but anatomical proofs of the same upon dissection after the disease has terminated fatally; in the meningic subdivision the complaint commencing in and being ordinarily confined to the meninges or membranes of the brain, the blood-vessels chiefly affected with inflammatory action being the meningic branches of the external carotid; and in the deep-seated subdivision the complaint commencing in and being ordinarily con- fined to the posterior part of the brain, the blood-vessels chiefly af- fected being minute branches of thebasilary artery. It^is neverthe- less possible, and appears often to become a fact, from the anastomo- ses that are occasionally found between different arteries of the brain, from the continuous spread of morbid action from neighbour- ing sympathy, or from some unknown cause, that either variety may pass still deeper or wider into the substance of the brain, and make an approach towards the other ; and hence the mixt, anomalous, and even contradictory symptoms, by which the specific character is sometimes distinguished ; a striking example of which, but too long to be quoted, is to be found in the Edinburgh Medical Commenta- ries.* " In three cases," says Dr. Sagar," I have found suppuration of the brain after death ; in each of which the patient during the progress of the disease breathed sonorously but without stertor.t Whether in the case of effusion between the membranes, the fluid be confin- ed, where the disease commences in the meninges, to the space be- tween the dura-mater and the arachnoid tunic, and where it com- mences in a contiguous part of the brain, to that between the arach- noid tunic and the pia mater, as asserted by Dr. Porter, I have not been able to determine." We may hence explain why the symptoms of irritation and op- pression should so much vary as we find they do in different cases; why there is sometimes no delirium and at other times a considerar ble degree ; why the delirium is sometimes furious and impetuous, constituting the delirium ferox of medical writers ; why in other in- stances it is mute or muttering, designated by the phrase delirium mite; and why there should occasionally occur examples of that comatose or heavy stupor to which the Greeks gave the name of typhomania; as also why the pain and pyrectic symptoms should vary from great acuteness to a mere disquieting head-ache and slight increased action. Phrensy is not often found as an idiopathic complaint, at least in this country; though it is a frequent attendant upon other diseases, as synochus, worms, various exanthems, trichoma, hydrophobia, in- juries of the brain, and severe grief. It sometimes makes a near approach to mama, but is easily distinguished by the nature of the exciting cause, where this can be ascertained, the abruptness of the * Vol. ix. p. 164. t Syst. Morb.

In the first variety or common quinsy, the swallowing is, for the most part, srreatlv impeded: and the speech, and sometimes even the respiration rendered higfhly troublesome : the mucus is excre- ted sparingly, and consequently there is a considerable clamminess in the mouth ; and the pain sometimes spreads to the ears. The disease is never contagious, and though violent while is lasts, is comparatively of short duration. It terminates by resolution, or suppuration ; hardly ever by gangrene ; though a few sloughy spots sometimes appear upon the fauces. The usual cause is cold ; and it is hence found most frequently in spring and autumn, when vicissitudes of heat and cold are most common. It is supposed to affect particularly the young and the sanguine—but, in my own practice, it has occurred as often at other ages and in other temperaments. When it has been re-produced several times w'thin short intervals of each other, it is apt to estab- lish a peculiar diathesis or habit, so as to be excited readily and by very slight occasional causes. If attacked by a medical process early, much benefit has been derived from astringent and acid gargles, and vapours inhaled by any simple machine for this purpose. Blisters to the throat or behind the ears, ought also to form a part of the curative plan ; and if bleeding be had recourse to, it should be by scarification or leeches applied to the tonsils or fauces. An early use of leeches I fiave often found highly successful. Cooling purgatives, and a low regi- men should also enter into the general plan of treatment. If sup- puration cannot hereby be prevented, the better way will be to ex- pedite this termination by the steam of warm water, or water im- pregnated with the leaves of rosemary or chamomile : and when the fluctuation is clear to the touch, if the abscess do not of its own ac- cord break readily, it ought by all means to be opened with the lancet. In a few instances the suppuration has pointed and broken ex- tern -illy, and the termination has been favourable.* And, occa- sionally, from the extent and violence of the inflammation, there has been so much danger of suffocation, that' it has been found ne- cessary to make an opening into the trachea :t which has been done sometimes as high as the larynx, and sometimes considerably lower • and under both kinds of operation the patient has recovered.! In the malignant or second variety, the inflammation passes * Schenrk. Lib. 11. Obs. 36. t Ballonius, i. p. 182. Fernire, Journ. de Med. Tom. lxii. X Fienus, Chir. Tract, iv. v. c. 1. Musgrave, Phil.

IV.] SANGUINEOUS FUNCTION. 229 at once into the ulcerative stage ; and is consequently characterised by the symptoms stated in the definition : the sloughing often takes place rapidly, and spreads widely, and the fever is a typhus. This variety is frequently epidemic; generally contagious; and found often as an alarming symptom in rosalia, or scarlet fever. In its idiopathic form it is usually ushered in with a sense of stiffness in the neck, accompanied with some hoarseness of the voice, and occasionally with symptoms of a coryza. It is in effect a quinsy, taking an erythematic or erysipelatous, instead of a phlegmonous turn, in consequence of the peculiar temperament of the atmosphere, or of the patient, or of some unknown cause. The sloughs at first appear whitish, or cinereous ; but soon be- come brown, and often black; and spread over the whole of the fauces, and mouth, into the nostrils, and often down the oesophagus ; the ulceration has, also, sometimes passed up the Eustachian tubes and affected the ears. And, as the sloughs appear to carry conta- gion with them, on being swallowed they have communicated the disease through the entire range of the alimentary canal. The danger is hence very great if the ulceration cannot be check- ed ; and it is peculiarly so to children and adults of relaxed and delicate frames. The disease makes its appearance most commonly in the autumn, though it has appeared in every season. Dr. Cullen regards the eruption of scarlet fever as a pathognomic symptom of this disease ; but this is to confound two complaints that are very clearly distinct, as we shall have farther occasion to ob- serve when discussing rosalia, or scarlet fever. It is at present sufficient to remark that, even in the opinion of Dr. Cullen himself, quinsy is not essential to scarlet fever, or, in other words, does not always accompany it; and that, on the other hand, a scarlet eruption is not essential to the malignant quinsy, or does not always accom- pany it, though he contends that it does almost always ;*—to show the proper bearing of these two diseases upon each other. The malignant or ulcerated sore throat may be without a scarlet eruption, or attended with it: if the former, it is an idiopathic af- fection, and constitutes a variety of paristhmitis, or cynanche. If the latter, it is a symptomatic affection, and constitutes a variety of rosalia or scarlatina. Cleanliness, pure air, and a free ventilation, are here of the ut- most importance : and as the contagion is often very active, the nurses should be cautious to remove speedily the sloughs and foul mucus that are washed or wiped from the mouth. The general treatment will necessarily be the same as that we have already pointed out for typhus. Emetics are often employed with great advantage at the commencement of the complaint; and the bowels should be gently opened, but not irritated with drastic purges. The throat should be gargled with port wine, made still more stimulant by spices or other aromatics -r or with a strong de- * Pract. of Phys. Part i. Book in. Ch. iv. Sect. dcli. 230 HiEMATICA. [CL. II1.-OR. II. coction of bark, or catechu, which is better, very sharply acidulated with mineral acids, or pungent Cayenne vinegar, or charged with an addition of Cayenne pepper in substance. Gargles of the mine- ral, and even the metallic astringents, have also been tried, but in general they want poignancy. Lunar caustic, in the proportion of one part to a thousand parts of water, has sometimes been found useful* A strong decoction of mezereon root may, also, advantageously form the basis of a gargle ; though even this will be improved by an addition of capsicum or Cayenne pepper,t and the mineral acids. The stimulus of mezereon is less acrid than that of Cayenne pepper, but is more permanent, and acts more immediately on the fauces. The leaves of the flammula jovis, (clematis recta, Linn.) or, the upright traveller's joy, may be masticated for the same purpose when fresh, for their acrimony considerably diminishes by drying. They excite a pungent heat in the mouth and fauces, and if chewed in a large quantity, produce a blister. In Persia, a gargle is obtain- ed by boiling the leaves of the water-pepper, (polygonum hydropi- per, Linn.) better known in the pharmacopaeias by the name of per- sicaria urens, which, in many instances, answers very effectually. And, in conjunction with these, camphor or ammonia has often been found beneficial when externally applied in the form of a liniment.| Bark and wine, indeed, should be taken jointly, and in as large a quantity as the system will bear. Even sleep is less necessary than both these ; nor should the patient be suffered to rest for a period of three hours at a time, without fresh doses of both, though we wake him for the purpose. Time, indeed, is here every thing: if we make no progress in the first thirty-six hours we may tremble for the event; if we lose ground in twenty-four hours, we shall have to hope against hope. Women, unaccustomed to wine, have taken it successfully under this disease, in the proportion of two bottles a-day, for more than a fortnight. Quinsy of the pharynx is, properly speaking, that which com- mences in this organ. It is met with but rarely ; nor is it, when it does occur, a case of serious importance. It is distinguished by the florid redness of the inflammation, especially at the lower part of the fauces, and by the nature of the fever, which is a cauma. The pain, indeed, extends sometimes behind the sternum, but is only felt in swallowing. The breathing is not affected A cure is easily in- duced by swallowing slowly nitrous and mucilaginous medicines, and taking off the phlogotic diathesis, where it prevails, by bleeding and brisk purgatives. * Journ. de Med.

It is doubtful whether this severe and dangerous complaint has ever been described till of late years. It seems to have been known to Dr. Mead, whose general account coincides with a disease noticed by Hippocrates. It is minutely and accurately detailed by Dr. Home, in his Principia; and is the subject of several excellent pa- pers in the Transactions of the Medico-C'hirurgical Society, particu- larly by Dr. Farre, Sir Gilbert Blane, Dr. Roberts, and Dr. E. Per- cival. The disease, as will be perceived by the definition, bears a considerable resemblance in many of its symptoms to croup ; is highly acute, and destroys by suffocation in a day or two, unless very actively opposed. Frequently, indeed, it destroys much sooner. Brassavoli mentions a case, which seems to have been of this kind, that proved fatal in ten hours :* and Schenck, another, in which suffocation and instant death were produced by a fit of vomiting, the spasmodic action having extended to the stomach or its auxiliary muscles.f The disease makes its approach with the common symptoms of inflammatory fever, as chilliness succeeded by heat; the voice be- comes hoarse and indistinct; the breathing laborious, with a pain- ful sense of constriction in the throat; the fauces present a Modena red colour, and are considerably swollen and turgid, the swelling extending to the face and eyes, the latter not unfrequently pro- truding, as in cases of strangling; the pulse is quick and the tongue furred ; and every attempt to swallow is accompanied with great distress; the muscles of deglutition, and even those of the chest, being thrown into severe spasms, threatening the patient with in- stant death from suffocation, and making him call out for air and an opening of the windows. It is distinguished from croup by the existence of a perpetual and voluntary hawking, rather than a forcible and involuntary cough, as though to clear the passage by expectoration. It is also distinguish- ed from it by the nature of the expuition which is a viscid mucus, rather than a coagulable and membrane-like exudation. The two * Comment, ad Hippocr. de Rat. Vict. acut. Lib. iv. t Obs. 29. ex Trincavellio, Lib. n. 232 HiEMATlCA. [CL. I1I.-0R. II. diseases differ, moreover, in their proximate causes as considerably as in their symptoms. Laryngitis consists in a suppurativ&nfian\- mation of the membranes of the larynx, extending backward to the membrane common to itself, and the oesophagus, between which pus is often found lodged: while croup or bronchitis is a peculiar in- flammation of the trachea, extending through the bronchial vessels, and exciting on their internal surface the secretion just noticed of a concrete filmy material which threatens suffocation by filling up the opening of the rima glottidis. In the treatment of this distressing malady, our object should be to take off the inflammation by the most active means. For this pur- pose eighteen ounces of blood should be instantly drawn from the arm, and eight or ten from the throat by leeches; and the bowels should be thoroughly purged by calomel and jalap, or some other active cathartic. In connexion with this process many wriiers advise the application of a blister, and the use of relaxant inhalatfons. But, in preference to both, 1 would recommend gargles of ice-water acidu- lated, and epithems of pounded ice applied externally. If this plan do not at once succeed, no time is to be lost, and bronchotomy must be had recourse to. But whether the opening should be made in the larynx, or below it, must be left to the judgment of the surgeon to determine. In a few instances, however, this disease seems to commence with comparatively little violence; and to run easily into a chronic form: a case of which kind is described by Mr. Wood in the Edinburgh Medical and Physical Journal. The child, a female, was ten years old when she was attacked. The symptoms for the first three or four days were even so trifling that no attention would have been paid to the complaint but for the croaking noise made in breathing, and particularly during sleep, which had a considerable resemblance to croup. The disease advanced gradually and almost'impercepti- bly, except by occasional exacerbations, with a pulse "from eighty to ninety in a minute, till the twenty-eighth day, on the noon of which the patient ate with an appetite, and with tolerable ease. At this period a night exacerbation carried her off suddenly; and on examination, the larynx was found internally covered and nearly filled with coagulable lymph, which is said to have assumed a mem- branous form; and hence approaching to the nature of the exuda- tion in croup.

(Croup. breathing permanently laborious and suffocative ; SHORT, DRV cough ; expectoration concrete and membranous ; FEVER a cauma. The writers on croup have given but one form of it, except what has been erroneously called spasmodic croup, a disease of a different kind which has already been described under the name of laryngis- mus stridulus. Properly speaking, however, there are two forms, an acute and chronic, under which the present species shows itself, and which may thus be distinguished as varieties : x Acuta. Sense of suffocation keen, and constrictive; Acute croup. chiefly seated in the larynx; respiration sonorous; voice harsh; cough ringing; great restlessness; terminating in a few days. fl Chronica. Sense of suffocation obtuse and heavy; chiefly Chronic croup. seated in the chest; cough severe, but in- Bronchial polypus, termitting; extending to some weeks or months. The disease, in both varieties, usually commences with the com- mon symptoms of a cough or catarrh; but essentially consists in a peculiar infla/nmation that spreads through different parts or even the whole range of the windpipe, from the larynx to the minutest ramifications of the bronchia?. In this extensive sense, the tube was called bronchus by the ancients; and I have hence preferred the term bronchitis to that of trachitis, or inflammation of the trachea, as such a term would imply a limitation of the inflammatory action to the upper part of the bronchus alone, to which it is not confined in either of the varieties before us. Bronchitis has indeed been ap- plied by Dr. Badham to a catarrhal inflammation of the bronchial membrane, but it would be better, perhaps, to regard this last af- fection as a variety of catarrh, than to treat of it as a distinct spe- cies under a distinct name. The first variety, importing the common or acute croup, the suf- focatio stridula of Dr. Home, who has the merit of having earliest called the attention of medical practitioners to it as a distinct dis- ease, though it extends thus widely, usually commences in the lar- ger parts of the tube ; during which a peculiar effusion is secreted that readily assumes a membranous form, and lines, not only the trachea above its devarication, but also its minutest branches, though voh. n. 30 234 II.EMATICA. [CL. I1I.-OR. II. the larger parts of the tube are first affected. When chemically examined, the secretion appears to consist chiefly, if not entirely, of the gluten, or coagulable lymph of the blood, diluted with its sero- sitv, and copiously combined with that peculiar substance of the blood, detected by the labours of modern chemistry, which, from its essential tendency to concrete into a fibrous, and even a membra- nous texture, has received the name of fibrin. By what means the mucous secernents throw forth this peculiar effusion on this peculiar occasion we know not. It is said by some writers to be secreted on no other occasion, and by no other org m; but this is unquestionably a mistake. There are few practitioners, perhaps, of accurate observation, who have not found it discharg- ed at times from the intestinal canal; of which I have already given examples under diarrhea tubularis; in which, as in croup, there is an inflammatory affection of the morbid organ, nnd a spasmodic constriction of the passage. In reality the effusion, distinct from the inflammation that gives rise to it, is not essentially different in its principles from what oc- curs in genuine polypus, or that of the nostrils, and those polypous concretions which are often to be found in other cavities : and hence Dr. Michaelis and some other writers have given to the disease the name of angina polyposa :* a term, however, inconvenient, and, in- deed, inaccurate, since angina, as commonly understood, imports in- flammation of the fauces accompanied with difficulty of swallowing, neither of which are necessary or even accidental symptoms of bron- chitis. This disease appears in the present day to exist in most parts of the world, and in the American states is called hives, supposed by my distinguished friend Dr. Hosack to be a corruption of the term heaves, and probably so named from the heaving or violent efforts of the muscles of the chest and abdomen which take place in breathing during its course. It is hence extremely singular that till within the last century it should either not have had any existence or not have been definitively noticed or described by medical writers: for Dr. Cullen appears to be perfectly correct in referring to Dr. Home as the first person who has given any distinct account of it.j It is also not a little singular that children should be chiefly sub- ject to its attack, at whose age fibrin is not peculiarly abundant, and whose blood contains comparatively but a small proportion of azote, which in fibrin is so large a constituent. These are among the ma- ny curiosities which the prying eye of physiology has yet to follow up: and much has it to accomplish before it will be able to explain them. Dr. Cullen asserts that acute croup seldom attacks infants till af- ter they have been weaned ; and that there is no instance of its oc- curring in children above twelve years of age. As a general rule * De Angina polyposa. Auctore Christ. Fred. Michaelis. 12mo. Argentor. 1779. + De Suftbcatione stridula. GE. VII.-SP. VI.] SANGUINEOUS FUNCTION. 235 this remark holds, but the disorder has been found occasionally in persons considerably above twelve years of age. Those who have once had it are more susceptible of it than before ; though the sus- ceptibility gradually wears off as they grow older. It is found equal- ly in midland regions and on the coast: but perhaps more frequent- ly in low, marshy grounds, than in drier uplands. There is no un- equivocal instance of its being contagious, though it seems to have been occasionally epidemic. It commences usually with a slight cough, hoarseness, and sneez- ing, as though the patient had caught cold and was about to suffer from a catarrh. And to these, in a day or two, succeed a peculiar shrillness and singing of the voice, as if the sound were sent through a brazen tube. At the same time, says Dr. Cullen, who has well described the progress of the disease, "There is a sense of pain about the larynx, some difficulty of respiration, with a whizzing sound in inspiration, as if the passage of the air were straitened. The cough which attends it is sometimes dry ; and if any thing be spit up, it is a matter of a purulent appearance, and sometimes films resembling portions of a membrane. Together with these symp- toms, there is a frequency of pulse, a restlessness, and an uneasy sense of heat. When the internal fauces are viewed they are some- times without any appearance of inflammation ; but frequently a redness, and even swelling appear: and sometimes in the fauces there is an appearance of matter like to that rejected by coughing. With the symptoms now described, and particularly with great dif- ficulty of breathing, and a sense of strangling in the fauces, the pa- tient is sometimes suddenly cut off''* To which I may add that the countenance exhibits great distress ; the head and face are co- vered with perspiration from the violence of the struggle ; the lips and cheeks are alternately pale and livid. The essence of croup consists in the secretion of this viscid and concrete lining, which is perpetually endangering suffocation. Dr. Cullen does not dwell sufficiently upon this symptom ; but ascribes this danger principally to spasmodic action, and represents the ac- companying fever, which, on his hypothesis, is also a spasmodic ac- tion, to be very considerable ; but spasm was with him, as we have already seen, a favourite doctrine, and his judgment was often warped by it. Dr. Marcus of Bamberg in Bavaria, who regards all fevers as inflammation of some organ or other, and as entirely seat- ed in the arterial system, regards croup also as a local inflammation alone, utterly independent of spasm, which neither exists here, nor in fevers of any kind: and attributes the danger to this symptom solely. That there is some degree of spasmodic action, however, as well as of fever, is unquestionable, though neither are very con- siderable ; and the locality of the disease as well as the peculiar character of the inflammation, sufficiently distinguish it from ca- tarrh, in which there is also some inflammation of the mucous men> "' Pract. of Phys. rccxxiv. 236 H/EMATICA. [CL. 11I.-OR. II. brane of the trachea, though of a common kind, and rarely limited to this organ. In children, however, it frequently treads close upon, catarrh, measles, hooping-cough, and any other disease that has de- bilitated the powers of the lungs : for as Dr. Michaelis observes, whatever tends to weaken or produce any degree of irritation in the lungs, so as to occasion a preternatural secretion into that or- gan, may be considered as a predisposing cause of croup. 'I he cure demands a prompt and active attention; and must de- pend not so much upon searching into and correcting the remote cause, or even counteracting the spasm, as in counteracting and re- moving the membranous secretion, which is every moment in dan- ger of producing suffocation ; and especially in children, in whom the natural aperture of the glottis is much smaller in proportion than in adolescents; and occasionally not more than a line and a half in breadth. There is in the patient a perpetual effort to remove this solid se- cretion by coughing; but the cough is for the most part dry and in- effectual, and nothing more than a little flaky mucus is8 excreted. V.ery copious bleeding* at the commencement of the attack, by breaking abruptly upon the inflammatory action, has sometimes car- ried off the disease at once. This M. Fieliz recommends from the jugular veins,! and M. Ghisi by topical scarifications ; but leeches will usually be found to answer best in infancy. Emetics have afterwards been tried, but with doubtful success: sinapisms} and blisters§ with as little. The inhalation of warm vapour, recom- mended by Dr. Home, can rarely he practised from the extreme restlessness of the little patient; and the remedy principally relied upon in the present day, and which certainly seems in many instan- ces to have operated like a charm, is large and repeated doses of ca- lomel ; of this not less than five or six grains are commonly given to very young children, and continued every two or three hours till there is a discharge of a green bilious matter, which seems to be the criterion of its having taken effect, and broken down the thicker part of the blood, from which the membranous secretion is princi- pally furnished. If this should not succeed, Dr Michaelis recom- mends tracheotomy, and has so little apprehension of its being at- tended with danger, that he advises it to be had recourse to soon after the attack, as affording a convenient opportunity of bringing away the preternatural membrane which serves as a lining to the trachea.|| But this advice is given with more courage than judg- ment. Whenever performed it should be after every other remedy has failed, and not before any other has been attempted. * Michaelis. Richter's Chir. Bibl. v. B. p. 739. t Fieliz. Richter's Chir. Bibl. vin.

VI.] SANGUINEOUS FUNCTION. 237 Under the genus laryngismus belonging to the second order of the preceding class, 1 have observed that the spasmodic affection there described, from its inducing a sense of suffocation, and possessing various other symptoms resembling those of croup, has often been mistaken for this last complaint, and been denominated spasmodic croup; though without the pathognomic sign of a membrane-like exudation, and for the most part without any inflammation whatever. It attacks children suddenly, most frequently in the night, and is apt to return in paroxysms, with short intervals of ease : whilst the real acute croup has no intervals, but continues its alarming course till it destroys the patient or yields to the means made use of. During the action of the spasm, however, there is a considerable hoarseness and shrillness in the voice, and, from the struggle, a profuse perspi- ration about the head and face. Violent as these symptoms are, they commonly yield to a brisk antimonial emetic : after the operation of which, the patient commonly falls into a sound sleep, and awakes with little remains of the complaint. The second or chronic variety of bronchitis, I have introduced chiefly on the high authority of Dr. Warren, who calls it, as I have already observed, a bronchial polypus ; a term which, as it often has done, may lead to mistakes; and which, in its application to any other part of the body, does not import the febrile action which exists as a characteristic of this disease. A concrete parenchyma- tous material, obstructing the bronchial vessels, coughed up in smaller or larger masses, sometimes easily and without any attach- ment to the sides of the bronchial tubes, and sometimes so exten- sively inosculated by radicles or radiating vessels, as to produce a fatal hemorrhage on their being thrown up with violence, has been noticed from a very early period in the history of medicine to the present day. Bartholine, Tulpius, Ruysch, Gretz, and Mor- gagni, have all been appealed to as giving examples of this affec- tion ; and it is very possible that even Hippocrates may allude to something of the kind in the case of Pherecydes who, he tells us, was accustomed to bring tip from his lungs in a fit of coughing, yxXaxrJisx, " white milky concretions;" and at length before he died o/ev m jmv|)j$ ftvtcqrx, \vnoTwvtx, tevxa QXtyftxrt Trt^n^oftnx, " firm mucus-like excrescences, surrounded with white phlegm."* But the complaint does not seem to have been distinctly described, till Dr. Warren's history of it in the Transactions of the College.1 The case by which he chiefly illustrates it, and which is here chiefly alluded to, is that of a young lady eight years of age, of a strumous habit, who was suddenly attacked with a difficulty of breathing, attended with a short, dry, and almost incessant cough ; but without any pain in the side or chest. The symptoms diminish- ed in the ensuing night, and the complaint appears to have been productive of little inconvenience* for six weeks; when it returned * De Morb. Popular. Lib. vn. Sect. xli. + Vol. i. Art. xvi. 238 ILEMATICA. [cl. iii.-or- n. with additional severity, with costive bowels, a white but moist tongue, and a pulse too quick to be counted. Bleeding, purgatives, and the oxymel of squills relieved her, but the breathing was still laborious; she had wasting night sweats, and the pul^e beat from a hundred to a hundred and twenty strokes in a minute for the ensuing twelve days, at the close of which period, she woke sud- denly in the night and was almost choked in bringing up, by cough- ing, what Dr. Warren calls "a large polypous concretion." It came up without either blood or mucus, and instantly gave her great relief. For two months afterwards she seldom passed three days without coughing up masses of the same kind, but none so large : she was tolerably easy when sitting still or in motion in the open air; and though her pulse never beat less than a hundred and twenty strokes in a minute, she had a good appetite, gained some degree of strength and flesh, and entirely lost her night-sweats. She was now suddenly attacked at night with another paroxysm of distressful breathing, and a sense of suffocation, and in the morning threw up a larger membranous concretion than at any time antece- dently, and in the course of the four ensuing days, a quantity quite as large as in the six preceding weeks. From this time the oppression on the lungs returned irregularly after intervals of five, eight, ten, or twenty days, always followed and always relieved by an expuition of the same concrete material; till at the close of a twelvemonth from the first attack, the patient complained of a pain in the right heel, an abscess formed there, and the os calcis was found carious. From this time the bronchial affection ceased, the breathing was perfectly free, and no more concretion was at any time thrown up. Dr. Warren conceived this concrete substance to have been an inspissated matter secreted by the mucous glands of the bronchial vessels. But the existence of fibrin, a» a constituent part of the blood, was unknown at the period in which he wrote ; and his plates and description of the membranous matter expectorated show evidently, that, like that discharged in croup, and often from the intestinal canal, it was composed of this formative element inter- mixed with gluten, secreted .in layers, and affecting a tubular struc- ture. " Some of these polypi,'"' says he, •• are of a much firmer texture than others, and bear shaking in water without breaking to pieces. Others are so tender that a very gentle motion in water breaks off a great many of their smaller branches. They are solid, composed of lamina?, which are easily separated from each other, and are manifestly of a texture-less and less firm as vou approach the centre or axis, which consists of a white pappy mucus as thick as cream. I observed one, about the size of a quill, which was tubular. It seemed to consist of a few lamella? only." In connexion with the plan of treatment already pointed out, it is highly probable that much benefit might, in this chronic form of bronchitis, be derived from the use of mercury and fox-glove. And as a natural cure was obtained by a metastasis, or a morbid GE. VII.-SP.

SPECIES VII. EMPRESMA PNEUMONITIS. iScrijmcumotts. inflammation of the lungs ; obtuse pain in the chest ; constant difficulty of respiration, alieviated by an erect position ; timid, purple face, or lips ; cough, generally moist, often bloody ; pulse usually soft. Inflammation of the lungs has been described under so many names that it is scarcely worth while to give a list of them. The most common perhaps is peripneumonia, for which pneumonitis, employed first, I believe, by Bourgard in his Dissertation published in 1754, is here substituted merely on account of the regularity of its termination. The disease as above characterized, is traced under the three following varieties:— « Vera. • Fever a cauma ; pain severe, little True Peripneumony. expectoration in the beginning. £ Maligna. Fever a synochus or typhus; the Malignant Peripneumony. debility extreme from an early period. Often epidemic. y Notha. Great secretion and expectoration Spurious Peripneumony. with a mild cauma. Occurring in weakly habits, and often con- nected with a catarrh. The first of these varieties, or true peripneumony, is, perhaps, the most common, and has been more generally treated of than the rest. Dr. Cullen has united inflammation of the parenchyma of the lungs, which is here alone contemplated, with inflammation of their membranes; as believing that we have no means of ascertaining a difference from the course or concomitancy of the symptoms. It may be observed, however, that in pleurisy the face is compara- tively but little flushed, and far less tumid ; that the pulse is harder; the cough less violent, and, from the beginning to the end, without expectoration ; the seat of pain also is here fixed : while in peripneu- mony, it shifts not only to different parts of the same side, but often from the one «ide to the other; and, when the lower part of the 240 HiEMATlCA. [CL. III.-OR. II. right lung is affected, is communicated to the liver, occasioning an uneasiness in the right hypochondrium, and accompanied with a yellow and copious expectoration. It is most commonly the case, however, that some degree of pleurisy accompanies pneumonitis from continuous sympathy ;* but then it is not idiopathic pleurisy, nor strictly possessed of its symptoms. Inflammation of the substance of the lungs bears nearly the same relation to pleurisy or inflammation of the membrane that lines it, as profound or parenchymatous cephalitis bears to meningic. The two former, however, are somewhat more distinct and less liable to run into each other than the two latter, because one half the pleura, from its duplicature, is more remotely situated from the lungs and less connected with them. And I have hence followed the ordinary division, and treated of pneumonitis and pleuritis as distinct species, rather than varieties of one common species, which is the view taken of meningic and profound cephalitis. In both sets of disease, however, the membranous is the more acute affec- tion, evinces more violent and painful symptoms, and runs through its course more rapidly. And hence, in pneumonitis, as in meningic phrensy, the pulse is sometimes soft,t the fever small,! anQl the pro- gress protracted occasionally to twenty days or more.§ The causes of true peripneumony are those of inflammation in general; particularly excessive exertion of the lungs, or cold, applied when the system is generally heated, to the skin, mouth, or stomach. It attacks the robust and plethoric more frequently than the spare and delicate ; and appears most frequently in cold weather or sudden changes from hot to cold. Repelled eruptions have' probably sometimes proved a cause ; and noxious exhalations cer- tainly. To the last we may refer the frequency of this disease in the outskirts of Mount Vesuvius, as remarked by Vivenzi ;|| and on this account it is described by BaroniuslT and Bovillet,** as endemic. The first symptoms also are those of inflammation in general; but there is usually more shivering, or cold fit, and the hot stage is proportionally violent; the head aches considerably, and the urine is high-coloured. The pain in the chest is rarely felt in any oppres- sive degree till these symptoms have continued for a day or two- though sometimes it is coetaneous. The cough is short, peculiarly distressing, and obstinate. The pulse is variable, in some case^ hard and strong, in some soft or oppressed; but, with the advance of the disease, it becomes feeble, sometimes fluttering. Delirium ■ Morgagn. De Sed. et Caus.

VII.] SANGUINEOUS FUNCTION. 241 is an occasional accompaniment, and is a highly dangerous symptom, except where it alternates with the pneumonic symptoms, in which case it augurs well. In favourable terminations the violence of the disease diminishes on or before the seventh day : if it increase beyond this, it commonly proves fatal. Peripneumony, like other inflammations, terminates in effusion, suppuration, or gangrene; and it has also a termination peculiar to itself, which is that of hemorrhage from an increased vis a tergo. The most salutary mode is effusion, for the vessels hereby become relieved, and the secernents immediately add to the relief by com- mencing an increased action, and consequently an increased dis- charge of mucus. In consequence of effusion, however, we occa- sionally find adhesions take place between the lungs and the pleura; and sometimes a collection of water in different parts of the chest; and not uni'requently a flow of blood, apparently from the mouths of the exhalents without any rupture of vessels, giving a bloody tinge to the sputum. This last has been often regarded as an alarming symptom, but the alarm is altogether unfounded, for it generally affords considerable relief. Indeed an hemorrhage itself from the lungs has not always been attended with fatal consequen- ces : it has occasionally proved critical, and carried off the disease in a few days: though a hemorrhage from the nose, no unusual at- tendant, is far preferable, as producing a like benefit with less risk. If the inflammation run into suppuration, the change is generally indicated by shiverings, with a remission of pain, and sometimes perspiration where there has been none before. If gangrene en- sue, the pulse sinks, the debility rapidly increases, and the eyes are fixed with a ghastly stare. The best, the easiest, and even the natural cure of peripneumo- ny is expectoration; which, hence, ought to be excited, and en- couraged by all the means in our power. It forms the optima crisis of Stoll, though, as he adds, a crisis too rarely obtained.* Bleed- ing, by giving some degree of freedom to the distended capillaries, affords one mean of accomplishing this object; but if the patient's strength be considerably reduced, the strength of the capillaries will be reduced also, and they will be too debilitated for the in- creased action. It is, hence, necessary to measure the general habit ami constitution of the patient, as also the situation in which he resides; for if he be in an open and mountainous region, and ad- dicted to the pursuits of a country life, he will bear bleeding far more reaJily and freely than if he be the inhabitant of a crowded city, or accustomed to a sedentary life. In this case the bleeding should be prompt and copious, at least to eighteen or twenty ounces, and repeated twelve hours after if necessary ; and as the disease occurs chiefly in robust constitutions, it is rarely that venesection can be dispensed with. The chief evil is that the fever is apt, at times, to run into a typhous form. ' Rat. Med. ill. 5:7. vol. n. :\l ^42 HJEMAT1CA. [CI- IH.-OR. »• and assume the second of the varieties before us. And hence, where there is any doubt upon the subject, local bleeding is to De preferred, whether by leeches or cupping glasses, repeated accord- ing as the evacuation appears to be demanded. Laxatives and re- frigerants are next employed with the same general view ot taking off the entony of the arterial system. One of the most common, and, at the same time, most useful refrigerants, is nitre ; which may be combined with the citrate of potash, or made to produce a more certain determination to the skin by the addition of camphor or of antimonial wine, or by a combination with the citrate or ace- tate of ammonia. Emetics have seldom been given except in an early stage of the disease, and then only as a gentle puke; yet, from my own prac- tice, 1 can recommend them when the disease has made a conside- rable advance : but they must be used boldly, or so as to produce full vomiting, and the action of vomiting must be maintained for an hour, or even two: and in this way they will often produce a transfer of action of as beneficial a nature as the same process is found to do in purulent ophthalmy; and will, at the same time, peculiarly stimulate the exhalents of the lungs to an increased se- cretion of mucus. Blisters, as is the common practise, ought to form a concomitant in the general plan ; and the obstinacy of the cough may be alleviated by demulcents, or inhaling the steam of warm water. Opiates have been tried in every form, but have never been found of decisive benefit: if opium be used at all it should be in conjunction with gum ammoniac, or squills: but, upon the whole, either of these expectorants seem to answer best with- out opium. Dr. Saunders recommended the extract of the white poppy ; and that of the garden-lettuce has since been tried upon the recommendation of Dr. Duncan; others may have been more fortunate than myself, but, in my hands, both have proved alto- gether insignificant in their effects. If the disease proceed favourably the pulse becomes slower and softer : the yellow tenacious, and perhaps bloody sputum, is mixed with points of a whiter matter, which increases with the amend- ment of every other symptom ; for the cough is less violent and straining, the breathing freer, the skin moister, and the tongue cleaner at the edges. If the progress be less favourable, the ex- pectoration becomes darker and more viscid; the pulse lower, in- distinct, and often intermitting; a low, wandering delirium super- venes, with subsultus ; and the patient dies, apparently suffocated from the oppressed vessels no longer permitting an expansion of the lungs. When a salutary expectoration has commenced, it sometimes ceases suddenly from some unknown cause, or some irregularity in the mode of treatment. This symptom is alarming; and every means should be instantly taken to bring the discharge back ; such, particularly, as increased doses of the expectorants already noticed, to which may be added the steam of vinegar, alone, or impregnat- GE.

And if a diarrhoea, which sometimes proves a very distressing concomitant, should subtervene, it will be best relieved by the pulvis cretae comp. cum opio. Inflammation of the lungs is, also, occasionally found as a symp- tom or sequel in rheumatism, lyssa, or canine madness, various ex- anthems, as small-pox, measles, miliaria, and commonly in phthisis; in which last it has a very frequent tendency to suppuration, as we shall have to notice when treating of this distressing complaint. The mvlignant peripneumony, contrary to the true, or common inflammatory affection, is generally an epidemic, and may be easi- est explained by describing it as an epidemic synochus or typhus* occurring in such situations, at such seasons of the year, or in such a temperament of the atmosphere as has a tendency to excite inflammation of the lungs. The debility is often so extreme from an early stage of the disease, that the pulse ceases on the pres- sure of the finger; and the vascular action is too weak to ac- complish expectoration. It is supposed by many writer-, and especially by Sarcone and Ludwig, to be a pulmonic erysipelas by which they mean an erysipelatous erythema: and they are probably right in their conjecture. Whence Planchon regards erysipelas as its proximate cause.t The symptoms are those already de-- scribed, with a great addition of sensorial debility, and conse- quently with increased laboriousness of respiration. The disease is usually fatal on the fourth or fifth day; and if the system be in- cautiously lowered by venesection or a laxative of too much power, it often takes place earlier; and has sometimes occurred within twenty-four hours after bleeding. Our attention must here, therefore, be turned rather to the con-' stitutional disease than to the local affection ; and the plan recom- mended in typhus is to he pursued on the present occasion : for it will be in vain to attempt expectoration under circumstances in which the system will probably sink before the usual time arrives for effecting it. Camphor is here a medicine of considerable ser- vice, and may be used in conjunction with the aromatic confection, and wine in large quantities. It should be taken freely in the form of pills, rather than in that of julep : though both may be employ- ed conjointly. Even the bark has a powerful claim to be t^ied, and that too in as large quantities as in putrid fever; nor has it been found to produce difficulty of breathing. It may be advantageously combined with the aromatic spirit of ammonia, which of itself often proves a useful stimulus. If evacuations be necessary they should be obtained by injections alone. A light breathing perspiration, a free expuition, and a more animated appearance of the counte- nance, are among the most favourable diagnostics. * Pelargus, Medicinische Jalirgange I. i. p. 44.

The spurious or bastard peripneumony is usually allowed to of- fer another variety of this disease ; and is described under the name of peripneumonia notha by Boerhaave, Coze, and Sydenham. It is, in many instances, little more than a severe catarrhal atlection of the lungs, accompanied with great obstruction, occurring in habits of a peculiar kind; and is hence denominated by many authors catarrhus suffocative It is characterized by great secretion and expectoration, with a mild cauma ; and is chiefly found in those of advanced life, or who have weakened their constitution by ex- cesses. Sydenham, however, has properly distinguished this malady from catarrh, notwithstanding the close resemblance it bears to it on particular occasions. The following is his description of the dis- ease :—The patient is hot and cold alternately, feels giddy, and complains of an acute pain in the head, especially, when there is a teazing cough. He rejects all fluids, sometimes from paroxysms of coughing, and sometimes without: the urine is turbid, and of a deep red ; the blood appears as in pleurisy. The patient breathes quick and with difficulty: complains of a general pain throughout the entire breast, and as he coughs discovers a wheezing to the attendants. The cheeks and eyes appear slightly inflamed ; the pulse is small, often intermitting; and lying low, or on one side, is peculiarly distressing. As the fever is here of no great moment, we may, with conside- rable advantage, carry our local stimulants to a greater extent, and thus excite the lungs more actively to throw off the burden of mucus with which they are overpowered. Squills, gum ammoniac, balsam of Peru, and even some of the turpentines, may be tried and will mostly be found serviceable. The tetradynamia, as char- lock, wild-rocket, and mustards of various sorts; and the alliaceous plants will form useful auxiliaries in the plan of diet. Blistering is highly serviceable ; after which, as soon as the chest is a little un- loaded, a regimen directly tonic should be commenced, by means of bitters, chalybeate waters, a moderate portion of wine, gentle exercise, pure air, and the irritation of an issue or seton: for a common result of this disease is hydrothorax from atony of the ab- sorbents of the chest. And hence, perhaps, more frequently fall a sacrifice to some sequel of the disease than to the disease itself. GE. VII.-SP. VIII.] SANGUINEOUS FUNCTION. 245 SPECIES VIII. EMPRESMA PLEURITIS. Pcurisg.

As the proper seat of the preceding species is in the substance of the lungs, or the pleuritic memurane that immediately lines its surface, or in both, the proper seat of the present is in the sur- rounding membranes of the pleura; and as these differ, the diffe- rence has laid some foundation for several varieties ; of which the three following may be noticed, as matter of curiosity, though the subdivisions lead to nothing of practical importance, as the causes are nearly alike, and the same mode of treatment is applicable to the whole. a Vera.

We have already pointed out the distinction between true pleurisy and peripneumony ; and observed that in the former the cough is dry and commonly without expectoration from the beginning to the end, contrary to what occurs in the latter; that the seat of pain is fixt, instead of shifting from side to side; and that the face is far less flushed and tumid. It must be conceded, however, to Dr. Cul- len, who has treated of these affections under one common defini- tion, that the general features of the two have a considerable re- semblance ; and, with the exception of expectorants, which in pleurisy are of little avail, the mode of treatment already proposed for the former disease, is the same that will be found necessary in the latter: the causes of both are alike, and as peripneumony rare- ly, though we have reason to believe sometimes, occurs without any 246 hjEMatica. [cl. iii.-or. u. degree of pleurisy, so it is commonly affirmed that pleurisy rarely occurs without some degree of peripneumony; in both which cases it has been called a pleuro-peripneumonia. Like the latter we also find the former an occasional symptom or result of typhus, catarrh, rheumatism, and various exanthems. The pleurisy, however, that is supposed to accompany rheumatism, is often an inflammatory af- fection of the intercostafor other thoracic muscles alone, since the pain is confined to the origin and insertion of the muscles. Where this has been accurately attended to, it has been distinguished by the name of bastard pleurisy. Like the preceding species, true pleurisy commences with the usual signs of a febrile attack, as chilliness or shivering, succeeded by heat and restlessness. The pain is usually just above the short ribs, and, as already observed, the expirations are less painful than the inspirations. The pulse is hard, strong, and frequent; and though the cough is mostly dry and supprest, there is sometimes a bloody or puriform mucus spit up from the lungs, evidently proving that the substance of the lungs has participated in the inflammatory action. Like the preceding species also, pleurisy terminates in resolu- tion, suppuration, and gangrene. The former is the ordinary and most favourable issue. The last occurs rarely ; but suppuration ie by no means uncommon; in, which case, if the abscess do not point outwardly, an empyema will necessarily follow; and the formation of pus is indicated by a remission of the pain, one or more shiver- ing fits, and, in some instances, a sense of fluctuation. This, how- ever, is a termination far more common to pleurisy from external injuries, than from internal causes. In the treatment of pleurisy, as we have no advantage to expect from expuition, we may employ bleeding far more extensively, and with far loss caution than in peripneumony. Perhaps there is no disease in which profuse bleeding from a large orifice may be so fully depended upon, or has been so gener- ally acceded to by practitioners of all ages and all nations. The only question which has ever arisen upon the subject being, wheth- er the blood should be taken from the side affected or from the op- posite. The earlier Greeks recommended the former, the Galenists and Arabians, the latter; and the dispute at one time rose so high that the medical colleges themselves, not being able to determine the point, the authority of the emperor Charles IX. was whimsical- ly appealed to; who, with much confusion to the controversy, died himself of a pleurisy before he had delivered his judgment. He too had been bled, and his death was immediately ascribed to the blood having been drawn from the wrong side. At present from a knowledge of the circulation of the blood, we can smile at these nugatory solemnities. It is possible, however, that there are some controversies of our own times, that have as little ground-work, and at which future ages may smile with as much reason. With these exceptions the treatment of peripneumony and pleuri- GE. VII.-SP. VIII.] SANGUINEOUS FUNCTION. 247 sy should run parallel. Purgatives should be used freely; blistering the side is very generally beneficial after bleeding has been tried and repeated, and should be accompanied with diluents and dia- phoretics. Opium may also be employed with less caution than in peripneumony. And where we have reason to suspect suppuration, warm cataplasms should be applied to the part to solicit an external opening. If the abscess break internally it must be followed by the operation for an empyema. The heart and pericardium are sometimes apt to associate in the morbid action, as well as the lungs themselves. This is particularly the case in »the second variety. Dr. Perceval, in his manuscript commentary on the Nosology, has given me a striking example of this in a patient who complained of excruciating pain in the region of the heart with dvspncea, not at all relieved by copious and re- peated bleedings. After death a slight effusion was discovered in the pericardium: but the mediastinum was more inflamed than the membrane of the heart. The treatment of this variety ought not to differ from that of the preceeding. The cerebrum is, however, still more disposed to associate in the morbid chain of action than in the heart. And hence, when any of the varieties of pleuritis, and particularly the last, are combined with an affection of this organ, and produce delirium, the disorder was formerly distinguished by the terms paraphrenesis, and paraph- renias ; terms derived apparently from the peripatetic philosophy, which supposed the seat of the v&tem of symptomatic no- sology 1iaa into a- treatise of practice. Dr. Cullen is right m as- signing- tneara' place in the former; and he is, therefore, necessa- rily wrong in banishing them from the latter; and the moie so, as the treatment ought in some degree to vary from that of enteritis, to which his general observation seems chiefly to refer. The true peritonitis occurs, as we have already observed, as a* symptom in puerperal fever; and as we have treated of it at some kmgti? Ji-.der that disease, it is the less necessary to be minute in our at/s-v^ at present. Puerperal fever, indeed, is sometimes, though no? qafte ctorrectly, made a variety of peritonitis : for it is a disease of a peculiar kind, produced by peculiar causes, and is iiuly connected with peritonitis as the latter enters as a symptom' i'.llo its general character. In what light Dr. Cullen regarded puer- peral fever does not appear from his writings, since, common as the complaint is, it does not occur in any of them; which is the more e^rrarordinary as his System of Nosology, Which is not comprehen- sive enough to include many diseases, might easily have found a place for this. In the specific definition it is stated, that peritonitis occurs " with' little affection of the subjacent viscera or abdominal walls." In ef- fect if often happens that these are not at all influenced, and when- ever they are,, fit is only secondarily. " If the peritoneum," says Mr. Hunter, " which fines the cavity of the abdomen, inflames, its inflammation does not affect the parietes of the abdomen ; or if the peritoneum covering any of the viscera is inflamed, it does not af- icctthc viscera. Thus, the peritoneum shall be universally inflamed as in puerperal fever, yet the parietes of the abdomen, and the proper"coafs of the intestines, shall not be affected: on the other" hand, if the parietes of the abdomen, or the proper coats of the in- testines are inflamed,, the peritoneum shall not be affected."* We hence perceive another proof that the membranous tunics of the different viscera do not hold an equal intimacy of action in every instance. And it would be interesting to follow up the dis- crepancy, and draw a scale of their readiness or inaptitude to sym- pathise with the viscera which they cover. The membranes of the inarn, as we have already seen, are so peculiarly disposed to partake of the inflammatory action of the parenchyma, as to render solitary inflammation e-f the one or of the other a rare occurrence. In the lungs the play of relationship is far less conspicuous and in the viscera of the abdomen it rarely takes place. And it is owing to this circumstance that we are able so generally to draw the line between inflammation of the peritoneum and of the intestines, from the pain being much more superficial in the former than in the lat- * On Blood, ice. p. 244. -yiE.

The causes are those of inflammation in general, as fold, exter- nal injuries, and a morbid transfer-of action ; ami, in or flannel swathe that surrounds, the entire body. All we .r::n.possi- bly aim at, in applications of this kind, is a continuation of moist warmth, as in a common poultice ; and this is-obtained more easily, a.id with infinitely less fatigue to the patient or danger of giving him cold, than in the ordinary way of applying-fomentations. When the bowels have been well opened, opiates may be given with free- dom, and-especially jr -ucisoe-w-ith ipecacuan-or a-nU.rxiQi.u3.ts £o de- termine fo the snrfi.ee. When ■'the inflammation commences oris seated in the omextcm or ephloo.v, the pain is more limited, and points rather towards the superior and middle region of the abdomen, a little above the navel; though it sometimes inclines to the light or left hypochondrium. The peritoneum itself does not readily pass into a secretion of ge- nuine pus; «and still less so the omentum, which, where ulceration takes place, generally evinces a foul and si.niotis-secreri.it/tL .Salva- ges gives a striking example of this in a woman, whe wiK/f.t'first at- tacked with an acute lancinating pain hi the umbilical region; and had a tumor formed towards the right hypochondrium about the size of a mans fist, which by cordia, and languid or intermitting pulse, which are its sure attend- ants. Upon the erythematic variety, the following remarks of Mr. Hunter are too valuable to be omitted : and they are the more va- luable as they apply to disorders of other internal cavities besides the stomach. " There is," says he, " an inflammation which at- tacks internal canals which is classed with the erysipelatous; but how far it is the same I do not know. It is certainly not the sup- purative. Whatever it is, it may be considered in some of its effects to be in direct opposition to the adhesive and suppurative inflamma- tions: for where the adhesive most readily produces adhesions, there the erysipelatous does not, as in the common cellular mem- brane ; and where the adhesive seldom takes place, excepting from extreme violence, there this inflammation (if erysipelatous) has a tendency to produce adhesions, as in canals or outlets. It also op- poses in some degree the suppurative, in being backward in pro- ducing suppuration even in those places where suppuration most \natoiny of the absorbent vessel?, p. )22, QE. tll.-SP. XI.] SANGUINEOUS FUNCTION. 255 readily takes place, such as canals and outlets ; for there, as above observed, it more readily throws out the coagulating lymph. Whatever the inflammation may be, it is certainly attended with nearly the same kind of constitutional affection. The fever in both appears to be the same, viz. accompanied with debility, lan- guor, &,c."* The erythematic inflammation of the stomach comes on more in- sidiously than the adhesive ; and is best characterised by the inflam- matory colour of the fauces, for it usually spreads to these, and the lowness and rapidity of the pulse. The inflammation often extends through a great part of the alvine canal as well as the oesophagus; and, after a subsidence of the sickness, produces diarrhoea, and mu- cous discharges from the bowels. It is sometimes so gradual and tardy in its progress as to produce little fever, or even local distur- bance, for many days or even weeks. De Haent has repeatedly referred to this sort of gastritis, and Hennings has described it more at length.;}; If this variety of gastritis be excited by acrid or poisonous sub- stances, a brisk emetic should be exhibited with as much speed as possible; and afterwards such antidote as the character of the poi- son may point out: opposing acids to alkaline, and alkalines to acid erosives, and the most active stimulants to narcotics. When the cause is internal, mild, diluent, and cooling drinks are to be em- ployed freely. The infusion of roses will often prove one of the most serviceable medicines we can make use of; blisters should be # applied and repeated, and the bowels kept cool by laxative clysters. Inflammation of the stomach is also found in the one or the other of its varieties, as an occasional symptom in aphtha, measles, small-. pox, and other exanthems ; and perhaps, in repelled herpes, scabies, and similar eruptions. * On Blood, &c. p. 270. t Rat.

In inflammation of the stomach the pain is seated higher, and is rather burning than griping; this last, also, has usually some de- gree of hiccough, and great dejection of mind; neither of which be- long to inflammation of the intestines; and it is by these charac- ters that the two are to be distinguished from each other. Stoll adds, that intestinal inflammation is also accompanied with a sup- pression of urine : but we cannot rely upon this as a specific symp- tom.

The causes of both, as also of the accompanying fever being a synochus, may be understood from the remarks already offered upon gastritis; the intestines partaking in a very considerable degree of the character of the stomach. To the causes enumerated under gastritis may be added some na- tural or accidental organic mischief in some part or other of the in- testinal canal, as ventral, inguinal, or other hernias, or introsuscep- tions of various kinds; or infarctions from coprostasis, scybala, or enterolithus. The plica polonica, or matted hair, is said by De la Fontaine to be a cause of this species, as other writers affirm it to be of gastritis. The progress of the first variety usually commences with a sense of coldness or shivering, and an uneasiness in some part of the belly, at first remitting or intermitting, but gradually acquiring permanency, and rising into an acute pain. The pain now spreads over the whole abdomen, which is tense and tender to the touch, though less so than in peritonitis; there is a great flatulency ac- companied with occasional spasms that shoot backward to the loins obstinate costiveness, and unconquerable vomiting. The pulse is small, hard, and frequent, but has sometimes been soft: the tongue dry; thirst extreme; urine high-coloured, small in quantity, and GE. VII.-SP. XII.] SANGUINEOUS FUNCTION. 257 discharged with difficulty; the breathing is laborious; and from the contraction of the abdominal muscles the patient is perpetually bend- ing forward. If no beneficial change take place, all these symptoms become aggravated; instead of feculent stools, there is an ineffec- tual straining, with a small mucous discharge; and with the in- crease of the retching the feces burst through the valve of the co- lon, and are occasionally thrown up from the stgmach. At length the torture suddenly diminishes; and the patient appears to have obtained relief: but his pulse intermits, his face grows pale, his ex- tremities cold, convulsions succeed, and he sinks in death. The general termination, therefore, when unfortunate, is that of gangrene ; for it is rarely that the inflammation runs into a suppu- rative state. If in the course of the first two, three, or even four days, a free feculent discharge can be procured from the bowels, the vomiting and pains will gradually diminish, the pulse abate in quickness, and the patient be in the way of recovery. In treating this complaint, it is hence of the utmost importance to procure free evacuations, for the cure depends almost entirely up- on our success in this respect. Yet the difficulty is often very great, and increased from the tendency of the stomach to reject whatever medicines are introduced into it. Most practitioners com- mence with bleeding, which they urge very copiously, and repeat every six or eight hours, according as the pulse will bear the lan- cet. The remarks we have made upon this practice, under gastri- tis, will apply to the present species. If the disease occur in a pa- tient of a hardy and vigorous habit, and particularly if we have an opportunity of employing venesection within the first day or two, we shall commonly find it of essential service : but if we do not suc- ceed, we shall assuredly hasten the stage of gangrene, and abbre- viate the term of remedial operations. And hence, unless free bleeding can be employed early, and the constitution evinces a to- lerable portion of vigour, there is no inflammation in which the lm- cet is less likely to be serviceable, or may become more, mischie- vous. To local bleeding, even under the conditions we are now supposing, there is less objection ; but we have less chance of benefit by it.than in peritonitis. Prom the first, therefore, we must attempt cathartics. If the stomach will retain the milder, as castor oil, neutral salts, or senna, these are by far the most advisable ; as our object should be to di- minish instead of increasing the irritation of the intestines. But in the first species thi- is rarely the ca*e ; and we must hence, without loss of time, apply to those that are more acrid ; as calomel in com- bination with the colocynth pill; assisting their operation by in- jections frequently repeated, and in as large quantity as the bowels will retain them. It does not necessarily follow that the irritation of these more acrid purgatives .ml add to the inflammatory irritation; nor do we * Tltpt Nouanswer readily, and sometimes the bowels have been mov- ed even by the tranquillity alone which the opiate has produced. Fomentations and blisters to the abdomen form a regular course of the therapeutic plan; and have, no doubt, been occasionally ser- viceable ; but, like local bleeding, they are less so in the present disease than in peritonitis. And where fomentations are adviseable, I prefer the epithem of a folded flannel wrung out in hot water, and confined with a swathe, as already recommended in peritoneal inflam- mation, to all other fomentations whatever. Injections of warm water alone, forcibly thrown up the rectum in as large a quantity as the bowels can be made to contain, are moreover often found of essential benefit, and are generally to be preferred to the warm bath, which, by adding to the debility, has accelerated the approach of gangrene. After the bowels have been freely emptied, diaphoretics, and especially combined with opiates, will be the best plan we can pur- sue ; and, if the stomach become quiescent, the patient should drink freely of diluents. There is a singular fact, noticed by Rhodius,* which sometimes occurs in this disease, and is peculiarly worthy of notice, as sustain- ing our hopes to the last: and it is this ; that occasionally, in the extreme moment of a seeming mortification, a sudden revolution takes place, and stools are evacuated ; and this, too, after the ex- tremities have begun to grow cold, and an apparently deadly lan- gour has overpowered the frame. In such case, we must snatch the patient from impending death by a free use of wine, and warm gene- rous cordials ; closely attending, at the same time, to a copious dis- *Cent. n. Obs. 69. UE. VII.-SP. XII.] SANGUINEOUS FUNCTION. 259 charge from the bowels, of which, with the liberal plan now recom- mended, we need not be afraid, and which we should be extremely cautious of checking by opiates. From the less threatening character of the symptoms, as they show themselves in the erythematic variety, this affection, as Roth- boel has well observed, often exhibits a fallacious appearance, and is misunderstood.* And it has hence been described on the conti- nent, under the names of occult, apyrectic and anodynet enteritis. Its real nature, however, is as we have explained it above. It has been well ascertained that the seat of this variety is sometimes in the external coat of the intestines ; and it is said, by some writers, that this is the most common seat. It is not easy to determine up- on this point: nor always, at its commencement, whether the inflam- mation be of the one variety or of the other, the modifying causes being, in some constitutions, and some seasons of the year and tem- peraments of the atmosphere, so nicely balanced as to leave the course doubtful. A case of this kind occurred to me in July, 1805, in a healthy and active young gentleman, thirteen years old. The abdomen was tense and tender, the intestinal canal painful through the greater part of its extent; the pulse quick, and moderately full; the skin very hot and dry; the blood, when drawn from the arm, without any huffy coating ; the sickness incessant, with deep anxiety and oppresion. The greater part of these symptoms indicated the adhesive variety; but, as the morbid signs increased, the stomach evidently partook of the affection, and shortly afterwards an ery- thematic sloughing appeared in the throat on the fourth day from the attack, evincing the real nature of the inflammation, and tha. it had extended up the whole of the cesophagus. On the sixth day the patient died. Bleeding, which was reported within about twelve hours, did not, in this case, prove of any benefit ; though it may be justified from the mixed character of the disease. But in distinct and simple ex- amples of erythematic inflammation, it ought, unquestionably, to be abstained from: and acids, and the milder tonics, and bitters, as infu- sion of roses, cascarilla bark, and cinchona, supply its place. 1 have said that enteritis is sometimes a result of hernias. It has also, occasionally, been produced by a forcible protrusion of a part of the intestinal canal through the anus ; of which a singular in- stance is given in the Medical Transactions, in a paper communica- ted by Dr. Latham :J the part of the prolapsed intestine was very considerable, and the injury was occasioned by the passage of the wheel of a cart over the loins; a portion of the mesentery was pro- truded with that of the gut; gangrene supervened to the inflamma- tion, and the prolapsed mesentery and intestine were cut off above * Dissert, sistens Observations circa fnllaciam signorniii in inflammationibus Abdominalibus.

The patient, who was a boy, recovered ; had motions regularly from the truncated extremity of the remaining intestine ; and was able afterwards to walk'twelve or fourteen miles a-day.

TENSION, SORENESS, AND PAIN IN THE REGION OF THE LIVER ; PAIN ABOUT THE .(IGHT SHOULDER; DIFFICULTY OF LYING ON THE LEFT SIDE J SHORT, DRY, COUGH. Inflammation of the liver, which may in general be sufficiently known by the above characters, has also two varieties, dependent upon its more rapid and violent, or more tardy and obscure march. a Acuta. In which the above symptoms are Acute inflammation of the clearly marked, and the charac- liver. ter of the disease is decisive. C Chronica. In which the specific character is Chronic inflammation of the obscure ; and tohe existence of liver. the disease suspected from a previous exposure to its causes, in connexion with an occasion- al recurrence of the pathog- nomic symptoms, accompanied with a slight degree of fever. Sauvages, on the authority of Amati, has given an erysipelatous, or, as it should rather be, an erythematic, variety of this disease, as Lommius has, also, done of pneumonitis; but the parenchymatous viscera do not seem to be subject to an inflammation of this descrip- tion, as Dr. Cullen has correctly observed ; and as has been since con- firmed by the remarks of Mr. Hunter which we have already quoted. The acute variety commences with the ordinary symptoms of visceral inflammation; dullness, succeeded by heat, frequent pulse, and a furred tongue: the bowels are irregular, mostly costive; the evacuations little tinged with bile, the urine often saffron-coloured ; the skin is dry, the thirst extreme, with occasional sickness. No physiologist has yet been able to explain the cause of the pain so generally felt in the right shoulder. It is however sympa- GE. VH.-SP. XIII.] SANGUINEOUS FUNCTION. 261 thetic of other affections of the liver, as jaundice, or chololithus, as well as of hepatitis; and hence it should seem to be produced by almost any morbid excitement of this organ, whether from inflam- mation or the obstruction of gall-stones. The cough, which is often very distressing, is easily accounted for from the vicinity of the diaphragfm to the seat of disease, and its sympathy with the liver. The «ic!;neps of the stomach is from the same cause. The disease is sometimes accompanied with a jaundiced colour of the skin; and Sauvages and Sager have made such a colour a spe- cific symptom; but it is not always that the bile regurgitates, and hence, such an appearance ought not to be enumerated among the pathognomic characters. Even where it exists it is not a distinct symptom of hepatitis; for, to say nothing of proper"jaundice, the feces, as Dr. Latham has well observed, may be light-coloured, and the eyes, skin, and urine peculiarly yellow, from the pressure of an indurated pancreas upon the bile ducts, and an obstruction of their course. And hence Dr. Latham imagines that an enlargement of the pancreas has sometimes been mistaken for hepatitis, and a diseased ovarium still more fre- quently. On which account it demands a very nice examination of the liver before we can speak with decision, and a pretty tolerable assurance to ourselves, that there is no enlargement of either of the other organs. Dr. Saunders, and with some plausibility, suspects the acute variety is owing to an inflammatory state of the hepatic artery, and the chronic to a like state of the vena porta?. Winslow ascribes both to an inflamed state of the ramifications of the vena portae, which, in his opinion, constitute the seat of the disease ; while Cullen refers us to the hepatic artery alone, and limits the seat of inflammation to its extremities. Dr. Heberden does not incline to believe that the liver is primarily affected, but only influenced by a phlogistic diathesis, or preceding inflammatory fever. If the inflammation originate in the membranes, the pain, as in most other cases of membranous affection, is peculiarly pungent, like that of a pleuritis; the fever is severe, the tension very consi- derable, the pulse frequent, strong, and hard ; the urine generally high coloured. When the substance of the liver is primarily affected, the pain and pyrexy are far less acute, and especially at first; but they increase with the progress of the disease, or, in other words, as it extends to the membranes, and not only darts to the right shoulder, but sometimes shoots as far as the throat and clavicle. Where the symptoms are most severe, and we have reason to suspect that the disease is confined to the membranes, the duration is often short, and the termination is in most cases that of resolution. But when less active, and seated in the parenchyma, it generally tends to suppuration; and if the convex side of the liver be the part affected, a tumour is visible externally, the cough becomes aggravated, and there is a difficulty pf breathing. If adhesions 262 HEMATIC A.

It has, occasionally, bv the same means, made its way into the stomach and intestines, wa.-:i- the hUc;>ss has been very large. In which case, however, immcdialelv upon the bursting of the vomica, the patient throws off, by sickness* or by purging, a large mass of most offensive matter, often filling the whole house with its noisome smell, and dies in a few hours? In like manner, the pus has occasionally formed an empyema in the thorax ; and, in a few instances, has been discharged from the lungs. The disease sometimes also terminates in scirrhosity; in which case the induration bears an extent in some -measure proportioned to the range of the preceding inflammation, and may often be felt by applying the hand to the region of the organ. This, however, is a more frequent result of the second or chronic variety. In order to induce acute hepatitis, it is necessary that the organ of the liver, at the time of attack, should be in a state of at least moderate health and vigour; for it is in this condition only, that inflammation running through its regular stages can take place, and hence the acute variety is found far more frequently in temperate, than in intertropical climates; and in the latter more frequently among new comers, than among those that have been long habituated to the climate, and whose livers have been weakened and relaxed by the greater heat of the sun : " Among the men of the eighteenth regiment," says Mr. Christie, who was stationed at Trincomale, and had the care of the entire garrison in 1798, " I found for the first six or eight months, the disease was much more frequent, much more violent in its symptoms, showed more tendency to suppuration, and was more sudden in its crisis, than with the company's Euro- pean troops, who had been long in India, although the latter were the most debauched. Among the natives hepatitis does not often occur: out of a thousand native troops, I did not, in the course of three months, meet with more than two cases of liver-complaints, which is comparatively a very small proportion."* There is, however, a striking distinction between the state of the bowels as affected by this disease in hot and in temperate climates. In the latter it is rarely we have any diarrhoea, and often an obstinate costiveness, the evacuations being mostly untinged with bile. In the former, from the higher degree of irritation that prevails, and the greater extent of its range, a bilious flux is so frequent as to be almost a pathognomic symptom; and as the gorged vessels are apt to give way from debility, this is sometimes intermixed with blood. In our own climate, bleeding at the commencement of the disease is generally found serviceable, and ought to be prescribed as speedy * Letter to the Editor of the Medical and Physical Journal, May 1798.

Free purging, with calomel and Epsom salts, should immediately follow ; and mercury be at the same time introduced into the system by the stomach, or by inunction, or by both. From the costiveness that usually accompanies the disease it is rarely necessary to unite the mercury with opium ; though where it irritates the bowels, the latter should unquestionably be given; as it should also to allay the cough, when this symptom is very distressing and prevents sleep. The mercurial course, as recommended by Sir James M'Grigor,* should be steadily persevered in, not only in hot climates but in temperate, till a salutary change has been effected, or salivation has been freely excited. It will often be found, however, that the patient will bear a long continuance of the mercurial plan without any affection of the mouth ; and will gradually and insensibly toi- prove under it; the soreness and tension subsiding, the cough diminishing, the pulse becoming slower, and the heat and dryness of the skin yielding to a pleasant moisture ; all which are prognostics of a favourable issue. The application of large blisters over the hypogastric region in succession, is recommended by most practitioners, but I have not found them successful; and have evidently derived more benefit from fomentations, epithems, and the warm bath. Diaphoretics should certainly form a part of the curative process ; and they combine admirably with the mercurial treatment; particu- larly the antimonial preparations. Cooling, diluent, and even acidulated drinks should be taken copiously ; the diet consist chiefly of light farinaceous foods ; and the chamber be well ventilated. If from sudden shiverings, and remission of the quickened pulse, we have reason to believe suppuration has taken place, columbo, the mineral acids, and above all the bark, where it can be retained, should be given freely ; the cinchona, at least in the proportion of from half a drachm to a drachm, five or six times a-day; and this whether the abscess be likely to burst externally or internally; and if the former, the direction should be encouraged by maturating cataplasms, and the abscess be opened as speedily as possible. The discharge is sometimes very considerable in quantity, and amounts to several pints ; the pus is occasionally found pure, but more generally intermixed with coagulable lymph or some viscid, yellow, fluid. It is at times lodged in different sacs, and hence subsequent tumours ensue, and subsequent openings are necessary.! It is not alway-, however, even after suppuration has taken place, that the abscess mast necessarily open in any direction ; for the following case will show that when we have full reason to believe * Medical Sketches, passim. t Recueil d'Observations de Medicine des Hopitaux Militaires, &c.

In the middle of last February, I was requested to meet in consul- tation Mr. Patten, and several other medical practitioners ot h.gli respectability, at Professor Gregory's of Woolwich Common, whose son, eight years of age, had, for nearly three weeks, been labouring under a considerable degree of fever, accompanied with a m x'ure of symptoms that gave no small degree of obscurity to the real nature of the complaint. The bowels were at this time obstinateh costive, the pulse at a medium of a hundred and thirty strokes in a minute, but varying from ten strokes above to ten below; there was a short, dry, distressing cough, and a slight difficulty of breathing; yet no observable pain about the right shoulder: the skin was nearly of its natural hue ; the motions, when procured, rather less yellow, and the urine rather more so than in common health ; the nights were without rest, and very fatiguing. The result of the symptoms had hitherto rather led to an idea of mischief in the chest; but finding on examination that there was a consider- able degree of tension and tenderness in the hypogastrium, rather verging towards the right, and connecting these signs with the preceding, I had no hesitation in pronouncing the disease to be hepatitis, and the opinion was unanimously* adopted. As the pulse, from the length of time the disease had now con- tinued, would not allow of general bleeding, twelve leeches were instantly applied to the region of the liver; an active cathartic was prescribed, and the patient put upon a course of calomel and anti- monial powder, of the former of which he took three or four grains a-day ; with an opiate at night. And, after the application of the leeches, a large flannel wrung out in hot water, was applied over the whole of the abdomen, and confined with a calico swathe, in the manner already recommended in peritonitis ; the warmth and moisture being rendered permanent by a renewal of the hot-water as soon as the flannel became dry, though it rarely required to be changed oftener than two or three times in the twenty-four hours. The application was peculiarly grateful to the patient. By this process a very favourable impression appeared to be made on the disease from the first; the pulse sunk to less than a huudred and twenty, and sometimes to less than a hundred ; the cough was less troublesome, the nights more refreshing, and the patient was able to retain more food. One of the most obstinate symptoms was the costiveness, which no ordinary aperient, even though aided by injections and the use of the calomel, was capable of alleviating; and which was only occasionally relieved by a combination of extract of jalap with that of aloes or gamboge, or both. In about a fortnight however, all the symptoms became more violent; the pulse rose to a hundred and forty, the cough was more troubl^ome ; the tension over the abdomen was more general, and there was an evident fluctuation over the whole abdomen, indicative GE. VII.-SP. XIII.] SANGUINEOUS FUNCTION. 265 of ascites. The fomentation was omitted but the calomel was con- tinued, and elaterium, gradually increased to three grains at a dose, in conjunction with the same quantity of extract of jalap, was given as a purge. In no proper proportion however did it operate as such ; it sometimes produced a watery evacuation or two, but never to any extent, and occasionally excited vomiting. It was omitted, and the digitalis, in unison with infusion of roses doubly acidulated, was given in free doses together with the calomel. At this time a violent shivering-fit took place, which made the teeth chatter; the pulse seemed rather to remit in rapidity, but the night was passed in hectic perspirations. Suppuration had no doubt commenced. The digitalis and calomel were omitted, a strong infusion of columbo acidulated with equal parts of nitric and muriatic acid prescribed in its stead; the right hypochondrium was covered over with a large plaster of the emplastrum ammoniaci cum hydrargyro; animal food was enjoined, and a small quantity of wine allowed. All the symptoms once more diminished ; the tension and perspiration subsided, the fluctuation was lost, the cough ceased, and the nights were refreshing. The patient con- tinued to amend about a fortnight, when the morbid symptoms again returned, though in a slighter degree, and seemed to show that some other part of the liver wasgaow affealeu.

SPECIES XIV. EMPRESMA SPLENITIS. Knflammatton of the Spleen. BEAT, FULNESS, AND TENDERNESS IN THE SPLENIC REGION ; WITH PAIN UPON PRESSURE. Of the use of the spleen, as observed in the Physiological Proem to the first class, we know little or nothing. It secretes no peculiar fluid except what serves to produce a change in its own blood, which is of a dark livid colour, and coagulates with difficulty. It is commonly supposed to be an organ auxiliary to the liver; and it is unquestionably subject to all its ailments; voluptuous living, how- ever, and even the heat of a torrid sun, affect it less; but obstinate tertians and quartans more, and render it sooner congestive and scirrhous. Inflammation of the spleen, together witBWhe symptoms given in the definition, is accompanied with the usual pyrectic signs; and often with a pain extending over the whole of the abdomen, but particularly in the left side, and shooting from the diaphragm to the left shoulder. There is also not unfrequently a dry, short cough, and sense of constrictfon in the praecordia, sickness or nausea, and a discharge from the rectum of black or livid blood, from a rupture of some of the splenic vessels. The common causes of inflammation of the spleen, are the same as those of the liver; and the treatment needs not essentially vary, as the progress and terminations of the disease are not different. In India, where it is more common than in temperate climates, the native practitioners use punctures and scarifications. The splenalgia, or pain in the spleen, of many writers, is for the most part a slight attack of this disease with some small degree of fever: and parabysma splenica, is a frequent result of both. In this last state the organ has been sometimes extirpated, either partially or wholly, without injury to the general health.* «Z ^' N?ooCur' DeC' r Ann-,V' Vl0bs- 1C1* Ann- VXI- 0b3- 15°- Valisiieri. ^>pp. III. p. 128.

Inflammation of the liftmen PAIN IN THE RENAL REGION ; FREQUENT MICTURITION ; VOMITING ; NUMB- NESS OF THE THIGH ON THE AFFECTED SIDE ; RETRACTION OF THE TESTICLE. The general causes of this species are whatever obstructs the flow of the fluids in the vessels of the kidneys ; as a wound, contusion, tumour, strain of the muscles of the back that press on the kidneys, excess of horse-exercise, various acrids conveyed to the kidneys by the course of the circulation. It is, however, most frequently met with as a secondary disease, resulting from calculous matter block- ing up the tubuli uriniferi, or from calculi formed in the pelvis of the kidneys, and obstructing that cavity or the canal of the ureters, concerning which we shall have to treat under the genus lithia, embracing calculous concretions in the urinary passages. The symptoms enumerated in the specific definition are sufficient to indicate the presence of nephritis, though the numbness and re- traction of the testicle are common to calculi in the ureters or body of the kidney, even when there is little inflammation present. In the case before us, however, the skin is usually hot and dry, the body qostive, and motion, and even an erect position, is accompani- ed with considerable uneasiness. By the last sign we may distin- guish the disease from an inflammation of the psoas, or almost any other adjacent musclefvvhile the immediate seat of pain separates it from colic, even when it is attended, as it is occasionally, with ventral gripings. Where the disease is violent, the urine is discharged in small quantity, and of a pale hue. And hence, if tlje urine become high- er coloured, be secreted in a larger proportion, and be at length thick and mixed with mucus, a gradual relief may be expected to follow, and the cure will be effected by a copious flow. The dis- ease sometimes passes off also by a metastasis. But if the symptoms be protracted beyond the seventh day, and there be stupor or heavi- ness in the organ, instead of acute pain, with frequent returns of chilliness and shivering, we have reason to expect that an abscess will ensue : in which event the pus may be discharged into the pelvis of the kidney, the abdomen, or, in case of adhesions, exter- nally through the integuments and the skin. The first is the most favourable issue, next to that of resolution ; the last is often suc- ceeded by a cure, but an evacuation of pus into the cavity of the abdomen rarely. In some instances the suppuration has been so considerable as to destroy the substance of the affected kidney en- GE. VII.-SP. XV.] SANGUINEOUS FUNCTION. 269 tirely, and leave nothing but the external membrane. Yet there are cases in which a patient has recovered even in this state, and the office of secretion has been performed by the sound kidney alone. Gangrene occasionally ensues, and is indicated by a sudden re- mission or cessation of pain; after great violence of vascular action; accompanied with cold sweats, a sinking pulse, discharge of black urine, and the other symptoms of approaching dissolution. In attempting a cure of nephritis, we should commence with copious bleeding; and in this case we may most conveniently employ cupping-glasses, applied to the region of the kidnies. Saline pur- gatives should follow; and then oleaginous or mucilaginous emul- sions, with small doses of nitrate of potash, or tincture of digitalis. The last has often proved highly serviceable in taking off the ar- terial action that maintains the inflammation, and at the same time in augmenting the urinary secretion. The loins should, at the same time, be covered with a large folded flannel wrung out in hot water, and confined as already described in the case of peritonitis; and copious emollient injections should be frequently thrown up the rectum, and suffered to remain there as long as the patient may be able to retain them. The rest of the treatment and regimen should be that of inflammation in general. SPECIES XVI. EMPRESMA CYSTITIS. Inflammation of the Iftatf&er PAIN AND SWELLING IN THE HYPOGASTRIC REGION ; PAINFUL OR OBSTRUCT- ED DISCHARGE OF URINE ; TENESMUS. The bladder is often irritated and inflamed by viscid substances that pass into the circulation, and particularly by cantharides, ardent spirits, and terebinthine essences or balsams. Idiopathic inflamma- tion is not a frequent disease ; yet it occasionally occurs as the blad- der is subject to the common causes of inflammatory affection : and it takes place both in its exterior coat, and internal mucous mem- brane. If the lower part of the bladder be chiefly affected, the pain will extend to, and take the course of the perinaeum. If the seat be in the neck of the organ, there will be a retention of urine with a constant urgency to evacuate; if in the fundus, the urine will flow stillatitiously, and without ceasing; the bladder will give a feeling of being constantly full; and the patient will be perpetu- ally and fruitlessly striving to empty it. In this affection there is 270 H^MATICA. [CL. IH.-OR. II. usually great restlessness and anxiety, with cold extremities, vomit- ing, delirium, and other marks of great general irritation : the dis- ease runs its course with rapidity, and subsides, or destroys the pa- tient, in a few days. It terminates, like all other inflammations, most favourably by re- solution. But if this do not take place, it passes on to suppuration or gangrene ; the diagnostics of both which are those already no- ticed in the preceding species. If suppuration take place, the pus may be discharged by the urethra, which is its happiest outlet; or it may follow the course of the ulceration, and be emptied into the cavity of the abdomen; or, if adhesions have been formed with the subjacent cellular membrane, it may work its way in a sinuous di- rection and find an opening in some part of the perinaeum. Of the last two terminations the first is almost always fatal; and the second is extremely troublesome and tedious, though a cure is usually ef- fected at last. Repeated bleedings, aperients, and relaxants, with copious emol- lient injections, suffered to remain in the rectum as long as possible, form the chief part of the plan of cure. Blood should be drawn both generally and locally, and a large bladder about half full of warm water be kept constantly over the pubes. The warm bath has also been frequently of essential service. When the urine is actually suppressed, it must be cautiously evacuated by a catheter. SPECIES XVII. EMPRESMA HYSTERITIS.

The most ordinary termination is that of resolution : the next that of scirrhus, sometimes running into cancer: both which are far more common to women who have never been impregnated, than to those who have had fami- lies. The concomitant symptoms vary according to the part of the organ in which the inflammation is seated. If this be chiefly in the fundus, the greatest distress of pain, heat, and throbbing, will be above the pubes; if the posterior part be chiefly affect- ed, the loins and rectum will principally sympathize, and there will be a troublesome tenesmus: if the inflammation attack the an- terior part, the bladder will participate in the ailment; the urine will flow with difficulty, but there will be a perpetual desire to pass water: while if the sides of the uterus or its ovaria be chiefly in- flamed, the pain will dart down the interior of the thighs. All the ordinary means already noticed for subduing inflammation, both general and local, should here be put into effect without loss of time, as venesection, aperients, emollient injections both into the rectum and uterus itself, and fomentations or epithems to the hypo- gastrium. The disease is sometimes cured by a metastasis, and sometimes by a sudden flow of the menses, with hemorrhage or genuine blood. The second variety, in which the symptoms are alike, but less acute, is usually, though not always a result of suppressed lochia, or violence sustained during labour, particularly from the use of in- struments. Bleeding is here to be avoided ; and the inflammation to be attacked with gentle laxatives, diaphoretics, and, where there is much irritability, camphor and opiates; fomentations and injec- tions being employed at the same time. It is a singular but well ascertained fact, that the spleen, from some unknown cause, is peculiarly apt to sympathize with the ac- tion of the womb, and at times, to run into an equal degree of inflam- mation, suppuration, or even gangrene ; and especially in females of a high nervous temperament. And so common is this fellowship of action, that most of the cases of diseased spleen related by Mor- gagni, are accompanied with an account of some mischief existing in the womb or its appendages. It is, however, to M. Gastellier of the Hospice de la Maternite, at Paris, that we are chiefly indebted for a knowledge of this peculiar sympathy, and especially in the case of uterine inflammation after child-birth. " La rate," says fe, " en a ete souvent frappee, mais une fois entr' autres elle a ete entiere- ment detruit, entierement fondue : iln'en restoit aucune trace, si non un foyer delfluide sanieux, dans la region, et en place de cet organe."' This passage from M. Gastellier is quoted by Dr. Ley, in a case of a similar kind which lately occurred to himself in the Westminster Lying-in-Hospital, and is given in the Medical Transactions of the College.* In this case, the preceding labour seems to have been * Vol. v. Art. xx. 272 HiEMATICA. [CL. III.-OR. II. perfectly natural and without any difficulty whatever. On the third day afterwards the disease seems to have commenced, indicated by intense pain over the whole of the abdominal region, with a slight sense of fulness, but without any considerable degree of tension. The patient sunk suddenly seven or eight days afterwards, and at a time when she was supposed to be in a state of improvement. On examining the body, the peritoneum and intestines exhibited little morbid affection of any kind ; and the disease was found limited to the uterus and spleen: the peritoneal covering of both was slightly inflamed, but the internal structure of both had undergone a very extensive destruction. The whole surface of the uterus, when stripped of its tunic, was found to assume a gangrenous appearance, was extremely irregular, of a. dark, livid hue, and gave forth a highly offensive vapour. The texture of the spleen was so changed as to resemble an extremely soft piece of sponge, and its cells were filled with an intimate mixture of pus and grumous blood. SPECIES XVIII. EMPRESMA ORCHITIS. Inflammation of the 3Testfcles/ PAIN AND SWELLING OF THE TESTICLES ; NAUSEA OR VOMITING J DEPRES- SION OF SPIRITS ; PULSE QUICK, SOMEWHAT LOW. Inflammation of the testicle has generally been expressed by the absurd and unmeaning name of hernia humoralis ; which, however, in its earliest use, applied to only one stage of the disease, namely the suppurative, and imported an abscess or collection of pus in any part of the scrotum ; and in this sense the expression occurs in Heis- ter and Dionis : being precisely synonymous with the empyocele of the Greeks. I have revived the Greek term orchitis, not only as being far more precise, but as accordant with the general termina- tion of the specific names of the diseases appertaining to the present genus. ^The inflammation seems commonly to commence in the tunica vaginalis, and to pass secondarily into the substance of the testis. Dr. Schwediauer contends that the testis never swells in the first instance, and that the disease always begins in the epididymis. The causes are irritation or external injuries. The most common irritation is venereal virus. Bleeding, laxatives, and cold lotions, with a suspensary bandage, form the curative process. Yet we have already observed that, when all local applications have proved in- effectual, the inflammation has been removed by vomits, in conse- quence of the close sympathy between the testis and the stomach. GE. V1I.-SP. XVIII.] SANGUINEOUS FUNCTION. 273 This was a frequent practice of Mr. John Hunter,* and especial- ly when the inflammation was the result of a syphilitic taint. It was successfully employed for the same purpose, and is hence strongly recommended by Rhazes,t and is a common mode of treatment on the continent, particularly in Germany :J after which opiates are often had recourse to, as well externally as internally. It may be worth remarking, that the affinity or play of action which thus prevails between the testis and the stomach, does not appear to be the common bond of union that is exhibited between the stomach, as the general centre of sympathy, and most other parts of the system ; but a fellowship of a peculiar kind, and which, in fact, does not terminate in the stomach, but extends to the upper extremity of the alimentary tube,, and exercises a very high de- gree of influence over the parotid glands, as is well known in e. parotitis, and has been already noticed in discussing this disease. In treating of e. hysteritis, I have had occasion to glance at the existence of a like sympathy between the uterus and the spleen : and the physiologist who has time for such pursuits, and judgment enough to guide him to a correct discrimination, would be engaged in no unthrifty employment if he were to follow up and arrange, in a regular classification, these specific and mysterious relation- ships, which single organs hold with single organs, and which are subordinate to the general harmony of the entire machine, GENUS VIII. OPHTHALMIA. ©jjhthalmg. Inflammation of the 33ge. PAIN AND REDNESS OF THE EYE OR ITS APPENDAGES : INTOLERANCE 0* LIGHT J FLOW OF TEARS OR OTHER DISCHARGE. Ophthalmia, from the Greek term oq>6xXfios, oculus, is obviously of very extensive import, and, from its radical signification, may be applied to any morbid affection of the eye, unless limited by com- mon consent. Now, although a sort of common consent has been given, so as to restrain the term to inflammatory action, such con- sent has not been universally acceded to ; and hence ophthalmia has been used in very different senses by different writers. Thus, * On Venereal Diseases. t Continent. Lib. xi. X Althof, Piactische Bemerkungen, &cr. Giitanner, Venerische Krankbeiten, Sir, vol. ii. • 35 274 HjEMATICA. [cl. Hi.-OR. II. Sauvages, Linneus, and Sagar, employ it as expressive of any ache of the eye, without reference to pyrexy or inflammation. Amongst all these, therefore, it occurs under their class dolores, and1 runs parallel with cephalalgia or cephalaea, ache or pain in the head. By Vogel, Cullen, and Macbride, it is limited to inflammatory af- fections of the eye; the two former arranging it as a genus, and the latter as a species. By Dr. Parr and Dr. Young it is also ar- ranged as a species, and limited to phlogotic action ; the second denominating it ophthalmitis, consonantly with the common termi- nation of names importing inflammatory diseases of a particular description of internal membranes, and organs. In the present system ophthalmia assumes a middle rank: it is limited to inflammatory action accompanied with organic pain, but is arranged as a genus. It might possibly have been placed as a species under the preceding genus, empresma, in which case it should have been written, as Dr. Young has written it, ophthalmitis: but it has various characters peculiar to itself, as well in regard to its symptoms, as to the particular parts of the organ affected, which seem to entitle it to the rank of a distinct genus. And thus ex- plained, its real meaning will be found in the generic definition; the symptoms of inflammation common to the order, and entering into the ordinal definition, being always understood as a part of the generic character. There is, perhaps, no disease in Dr. Cullen's First Lines that is treated of so slightly and unsatisfactorily as opthalmy. He gives only one idiopathic species, into which he resolves all inflammato- ry affections of the eyes that are not symptomatic of other com- plaints ; and he considers this merely as modified into two varie- ties, from the inflammation being seated in the membranes of the organ, or on the edge of the lid. When we compare this abbreviat- ed view of the inflammatory diseases of the eye with Dr. Plenck's methodical arrangement of its ailments altogether, and behold the latter enumerating not less than one hundred and nineteen genera, comprising very nearly six hundred species, although a regard to our own ease may dispose us rather to take part with the abbrevi- ating spirit of Dr. Cullen than the discursive genius of Dr. Plenck, still it is impossible for us not to perceive that the former has been too summary in his arrangement; and, if we follow up his arrange- ment into his therapia, too summary in his therapia also. It is true, indeed, that since Dr. Cullen's time, the maladies of this or- gan seem to have increased, and this too, in one at least, perhaps more than one, of its most virulent and fatal affections, as the con- tagious purulent ophthalmy ; but then this addition has taken place, also, since the arrangement of Dr. Plenck, who would otherwise, no doubt, have found the means of extending his list by the inven- tion of new genera and species, to nearly a hundred more maladies of the eyes ; so as to have treated us with a catalogue of nearly seven hundred, instead of six hundred, distinct diseases of this sinele organ. 5 GE. VIII.] SANGUINEOUS FUNCTION. 275 After no small degree of consideration, it appears to me that ophthalmia, or inflammation of the eyes, may embrace all the dis- eases that belong to it, as a genus, under the five species of inflam- mation of its coats generally ; inflammation of the muscular fibres of the iris ; inflammation of the internal surface of the eye-lids asso- ciating with that of the globe ; inflammation of the tarsus or edge of the eye-lids; and the chronic inflammation which is often found as a sequel to most of these. 1. ophthalmia taraxis. 2.----------IRIDIS. 3.--- 4. --- S. --- — PURULENTA. — GLUTINOSA. — CHRONICA.

This is the common inflammation of the eyes produced by cold, dust, or any other external irritation, as excessive light, vivid co- lours, blows or wounds: and has been often called, and with great propriety, lachrymose ophthalmy, as the morbid secretion chiefly excited is that of tears. By Paul of iEgina it was named taraxis, from t%»»7vm " to disturb, confuse, tumultuate," in allusion either to the violent action that takes place, or the confusion of the ob- jects presented. And as the Greek name has been very generally continued by medical writers, and especially those of the Conti- nent, to our own day, I have employed it in the present system, to distinguish the species before us. It occurs under two varieties as follow: x Mitis. Mild Lachrymose Ophthalmy. S Acuta. Acute Lachrymose Ophthalmy. The inflammation limited to the sur- face : the pain passable: the head not affected. The inflammation extending to the lower part of the eye-ball: and sometimes commencing there: the pain burning: the tears perpetual and acrid: with intolerable head- ache. 276 H4MATICA. [<*- "I.-OR.

If the inflammation commence in one eye it will generally extend to, and sometimes alternate with the other; and during sleep a glutinous fluid is secreted which collects towards the angles, and sometimes so closely cements the eye-lids, that it is with difficulty they are opened in the morning. > In ordinary cases, this milder modification of ophthalmy runs its course in four or five days, and ceases spontaneously, or is easi- ly removed by local applications, and particularly astringent lo- tions, as cold water, or solutions of alum, zinc, or lead ;* though, in irritable habits of a particular kind, relaxants and anodyne fo- mentations prove most successful. And even when the first are employed, it is always best to wash off the adhesive fluid, that glues the eye-lids together during the night, with a little warm water in the morning, before a free use of them. In the second variety, constituting the chemosis of Plenck, and produced from the same causes as the preceding, the symptoms from the first assume great violence; the inflammation passes rapid- ly from one part of the ball to another; a keen darting pain pene- trates frequently to the bottom of the socket, accompanied with a burning heat, and intolerable head-ache ; the temples often throb, and the pulse is quick. The most active measures are here necessary from the earliest commencement; for, from the violence of the inflammation, ulce- ration may take place internally or externally, and the pupil be irretrievably lost. Copious bleedings by leeches or cupping-glas- ses, are usually recommended from the temples; but large and re- peated general bleedings carried on to syncope will be found far more successful ; and if the blood be taken from the temporal arte- ry, the success will be still more certain. Brisk purgatives should at the same time be employed, and blisters applied to the temples, or behind the ears. The room should be kept moderately dark, but cool and airy; and astringent lotions, chilled by ice or frigorific mixtures, be constantly applied to the forehead, temples, and eye- lids, by folds of linen successively wetted for the purpose. * Janin, Beobachtungen iiber das auge, &c.

The patient, whose history he describes, was a young woman, aged twenty-two, of a delicate habit. The attack was sudden, and pro- duced a total inability of sight in the right eye. The tunica albu- ginea, and indeed the whole globe of the eye were preternaturally enlarged, and the former in a considerable measure covered with deeply-inflamed red vessels; the cornea being greatly distended, and the crystalline lens apparently protruded, by an accumulation of fluid, through the pupil so as to be in contact with the inner sur- face of the cornea itself, possessing an irregular and unequal form. The eye-lids were very much swollen and glued together; the ad- mission of light and air was insupportable ; and followed by a copi- -ous discharge of acrid tears; and the whole was accompanied with excruciating and incessant pain, entirely preventing sleep, and sometimes so intolerable as to induce fainting. The left eye was similarly affected, but in a less degree. Copious and repeated bleeding from the temples, blisters, purgatives, shaving the head an;! cold applications to it, and all other means that could be thought of, had been tried, but to no purpose. As a doubtful and desperate remedy, a tartar emetic mixture was prescribed of which the patient was to take a large spoonful every hour till it vomited or purged her. The second dose both vomited and purged ; after this at bed- time, she took a grain and a half of Thebaic extract with two grains of ipecacuan. She passed a quiet and composed night, and enjoyed more sleep, and far more comfortably than she had done during all her illness. The tartar emetic mixture was continued the next day in smaller quantities, and in a few days more she recovered her former health and strength.* Where the inflammation is a mere symptom or concomitant of some other disease, it can only be removed by a cure of the original ma- lady. And this is not unfrequently the case ; for it is often depen- dent on a strumous, or syphilitic habit or a suppressed blenorrhcea : on a disordered state of the stomach, liver or some other digestive organ, and especially in hard drinkers; on an abuse of mercury as a medicine ; and on various affections of the teeth. If the inflammation be produced by an influx of sand or gravel, or spiculae of flint or iron driven into the external tunic, every such foreign substance must be carefully removed with as much speed as possible: but it will be generally found that the pointed and Edin.

We have vari- ous examples of an extraction of spicule of iron forcibly driven int« the eye, by the application of a magnet.* SPECIES II. OPHTHALMIA IRIDIS. Inflammation ot the Ins. inflammation commencing in the iris ; COLOUR changed to GREEN OR REDDISH ; FIBRES LESS MOVEABLE ; AND SHOOTING DENTIFORM PROCESSES INTO THE PUPIL ; PUPIL IRREGULARLY CONTRACTED AND GREYISH. Dr. Schmidt of Vienna, to whom we are chiefly indebted for an ac- curate description of this species, has denominated it Iritis ;t and under this name it has of late years been described by many practi- cal surgeons in our own country. The termination, however, is unclassical, and if the derivative be retained, it should unquestiona- bly be iriditis instead of iritis; but ophthalmia iridis is better, as the disease is very clearly a species of a connexive genus of dis- eases rather than a distinct genus itself. The exact change of colour which the inflamed iris assumes, first in its less, and then in its greater circle, depends upon the peculiar colour it possessed when in health. If this were greyish or blue, the morbid hue will be green ; if brown or black, it will be reddish. The greyish or cloudy appearance of the pupil is produced by the secretion of coagulable lymph which spreads over it in a fine flake like a cobweb. If the inflammation do not yield to the curative treatment, a yellowish red tubercle forms some part of the surface of the iris, commonly where the greater and less circles of the mem- brane meet; it enlarges, projects still forwarder, and is distinctly seen to be an abscess which at length bursts and discharges its con- tents into the anterior chamber. The inflammation now diminish- es, the pus and blood, if any be thrown forth, are absorbed; and the disease subsides, but with a total loss of vision ; for the iris remains permanently expanded with an utter inability of motion, and the * Morgagni, De Sed. et Caus.

VIII.—SP. II.] SANGUINEOUS FUNCTION. 279 pupil is closed or rather filled' up by the greyish or ash-coloured web or membrane already noticed. The most frequent cause of this distressing affection is the opera- tion for the cataract; in which an irritation is often excited either by endeavouring to press out the lens through too small a wound in the cornea ; by suffering some pieces of the lens to remain in the posterior chamber; or from too frequent an exposure of the inter- nal surface to the air by unnecessarily raising the flaps of the cornea. Like several other species of ophthalmia, this also occasionally shows itself during the existence of a syphilitic taint in the system. And where a patient is labouring under an arthritic diathesis, and is accidentally affected by a common ophthalmy, this species is apt to be engrafted upon it. The medical treatment is both local and general. The first should consist in freely emptying the vessels by venesection, leech- es, and active purgatives: blisters are then to be applied succes- sively to the temples, behind the ears, and on the nape of the neck. Cold local applications are quite useless; and the only admissible collyrium is a fomentation of the eye with water made as hot as the patient can bear it, which will often mitigate the violent pain; the eye being carefully wiped dry after using the application. The general treatment of the disease consists in the introduction of mercury into the system. This is particularly insisted upon by Mr. Travers, who has written a valuable article upon the subject. Whether it be a primary affection, or connected with other diseases, even with syphilis, or induced by the action of mercurial prepara- tions, he estimates this as almost a specific remedy.* Mr. Travers distinguishes also inflammation in the iris from that in the cornea, by regarding the latter as suppurative, and leading to an abscess, and the former is adhesive alone. And he tells us that inflammation of the cornea so strictly maintains this character, that if it spread to the iris, and in this case become merely secondary, it still preserves its adhesive power. This species is also sometimes a concomitant of cutaneous erup- tions, decidedly not syphilitic ; and especially of .those produced by a very extensive use of mercury ; constituting what has been deno- minated by some writers erythema mercuriale, and hydrargyria, as we shall take occasion to notice under syphilis. In the syphilitic or arthritic affection however, a particular atten- tion must be paid to the primary disease, since otherwise no local remedies can be of any avail. * Surgical Essays, &c. i. passim. 280 HiEMATICA.

Appearing suddenly and without any Purulent ophthalmy of in- ostensible cause in new-born in- fants, fants: the palpebral florid, and pe- culiarly tumid. The first, or Egyptian variety, is that concerning which so much has of late years been written by French and English surgeons and physicians, and which proved so extremely destructive to the armies of both nations in their respective expeditions to the banks of the Nile ; the real nature, however, and cure of which have only been very recently discovered in our own country, to the great benefit of the numerous blind pensioners of Chelsea and Greenwich hos- pitals. This disease was at first ascribed to the minute and glassy spiculae of the sands of the Egyptian plains. But it has since been sufficient- ly traced, either to a peculiar miasm generated in marsh-lands, or to sleeping on damp or swampy ground, with insufficient covering, and surrounded by a moist atmosphere. And as these causes exist in GE. VIH.-SP. III.] SANGUINEOUS FUNCTION. 281 other parts of the world than Egypt, the disease has been since de- tected in other parts as well. A peculiar miasm, however, formed in hot and swampy soils, is perhaps the real cause ; for it is otherwise almost impossible to ac- count for no existence or description of the disease in earlier times: and however difficult it may be to conceive the origin of such a miasm in one period of the world rather than another, this is a diffi- culty that extends equally to all infections, as well as to various other maladies. The cause, be it the one or the other, necessarily renders it epidemic; and the pus, as in one or two of the succeeding varieties, secreted apparently from the sebaceous, or rather the mucous follicles of the tunica conjunctiva (for M. Bichat is probably right in regarding the Conjunctiva as a mucous membrane) is im- pregnated with a specific contagion ; and hence the disease is pro- pagated with great rapidity between those who come in contact with each other, by sleeping together, or using the same towels. I have known it caught by a surgeon's assistant merely in conse- quence of syringing the eyes of a patient, a part of the discharge having, from the force of the syringing, spurted into one of his own eyes, which was for some days in a State of danger. The general symptom* and progress of the disease are those al» ready noticed in the definition. From the violence of the morbid action, the eye-lids soon become excessively tense and edematous, sometimes inseparably closed, with the edges drawn inwards, and sometimes gaping with the edges broad, turgid, and everted. The secretion of pus and tears is prodigious; and the pus is discharged thus freely even when there is no ulceration. But an ulceration often takes place, and sometimes during the first night of the attack. It commences usually in the cornea, which, from the onset of the disease, looks more or less muddy, or is studded with white spots. The ulcerative progress is sometimes checked before it spreads over the whole disk of the pupil, and, in this case, the sight is par- tially preserved. But, very frequently, it makes a rapid and irre- sistible advance over the entire cornea, lays open the iris, and works its way to the membranes, and even to the cellular substance below: in consequence of which the aqueous, and a part of the vitreous humour escape, the iris protrudes, and more or less ad- heres to the ruptured cornea, and the eye loses its figure as well as its power of vision. The pain, through the whole progress, is in- tolerable : in the eye itself there is a sense of scalding or burning, and an agony in the head that drives the patient mad. In some cases the symptoms are less violent, and gradually sub- side without ulceration, in three or four days; and especially where the disease has been actively opposed by the process we shall have to notice presently. But innumerable granulations have, by this time, often formed upon the conjunctiva of one or both eye-lids, and a destructive irritation is hereby still kept up, which becomes a secondary source of blindness. The earliest mode of treatment pursued'by the French,, as we vox., ii. 3G 282 KffiMATICA. [CL. III.-OR. It' learn from the account of Dr. Antonio Savaresi, consisted in httle more than the general treatment of the common acute ophtna.my, as local bleeding, drawn, however, from the jugular vein or tem- poral artery, blisters, saline purgatives, anodyne lotions, and a low diet. The bleedings do not appear to have been very copious. And yet this writer tells us that by this process alone he was so fortunate that out of a thousand or thereabouts, who were confined in the French military hospitals in Egypt under his care, not more than two lost their sight completely, though some others suffered the loss of one eye. In the hands of our own army practitioners the plan ot treatment thus limited, completely failed of success j and the bleeding, which was almost solely depended upon, was carried, from the first day of the attack, and repeated for several days afterwards to as great an extent, not only as fainting, but as life itself would allow. The first accounts we had of this practice seemed to show that it was in the highest degree successful :* but later experience has not justified the representation, and the extensive lists of blind pensioners at this moment supported by the Chelsea and Greenwich hospitals, are a sufficient proof that the success of the evacuating plan was consi- derably exaggerated. The late Mr. Saunders was, in consequence, induced to turn his attention upon its full stretch to this most acute and maddening dis- ease : and he was the first to discover that the blindness which is so apt to follow, even after the first attack of virulent inflammation has subsided, proceeds from the friction upon the transparent cor- nea, of innumerable irritating granulations thrown forth from the surface of the tunica conjunctiva that lines the interior of the pal- pebral, and which become a new source of inflammation, less violent indeed, but as fatal in its effects; and the disease has hence been very correctly divided into two stages, that of primary and that of secondary or granulating inflammation. Mr. Saunders endeavoured to cut the disease short in its first stage by exciting nausea, and maintaining it for a considerable period of time, so as to lower the living power, and hereby take off the inflammatory action. And where the disease had proceeded to the granulating stage, he re- moved the minute caruncles from the tunica conjunctiva by cutting them off with a pair of scissors, and afterwards applied a solution of nitrate of silver to prevent their sprouting again. Sir William Adams appears very essentially to have improved upon both plans. Instead of the nauseating process employed in the first stage, he boldly pre- scribes active and powerful vomiting continued for eight or ten hours by giving two grains of tartar emetic at first, and continuing one grain every half hour afterwards through the whole of this period; by which violence a change of action, or new but more manageable excitement seems to be produced in the eye, and the * Account of the Ophthalmia which has appeared in England since the return of he British army. By J. Veitch, M.D. GE. VIII.-SP. HI.] SANGUINEOUS FUNCTION. 283 disease is stopped in the course of ten or twelve hours from its on- set. And where the second or granulating stage has commenced, he slices away by a knife the diseased surface of the conjunctiva, instead of the granulating points alone ; by which the morbid action is destroyed not only with less pain, but far more radically and effectually; and he afterwards employs a solution of alum, instead of a solution of nitrate of silver, as the latter is hereby rendered unnecessary ; not to mention that the agony it excites is almost in- tolerable, and that a new inflammation has followed, in some in- stances almost as dangerous as the original inflammation itself. Emetics, indeed, have long been occasionally made use of as a means of relieving inflammation in the eyes ; but not in the parti- cular kind before us, nor, perhaps at any time of inflammation at present with the precise object in view, proposed by Sir William Adams. Stoll, for instance, employed them successfully in periodic ophthalmies ;* and Dobson, as already observed, in ophthalmies of a like chronic kind, accompanied with nervous debility; the bark being interposed between their repetition.? The nearest approach, however, to this practice which I have met with on medical records is Dr. Dobson's case, already noticed under acute taraxis. In the second or metastatic variety, the inflammation of the eye is produced by a transfer of action or secretion from some other organ; as on a sudden suppression of the discharge that takes place in the nostrils during a catarrh, or in the qrethra from venereal infection. The mucous membrane that lines the ball of the eye, and is a duplicature of the tunica conjunctiva, has a near resemblance to those which line the urethra and the nostrils, and all are easily excited to a very copious secretion of purulent matter. This in effect is the immediate cause of the purulent ophthalmy in each of its varieties. And it is not therefore very extraordinary, as we are perpetually meeting with examples of a transfer of action in almost every other part of the body, that the mucous membrane of the eyes should occasionally become the seat of a metastasis or transferred action from organs that so nearly partake of its nature : and it is still less wonderful that such an effect should occur where the whole system is impregnated with syphilitic virus ; a subject of inquiry, however, that belongs rather to the genus syphilis, than to the present place. The symptoms, under such a translation, are those of the Egyp- tian ophthalmy ; the disease is often as violent and dangerous, and requires to be treated in the same manner. 1 have noticed this va- riety upon the concurrent testimony of St. Yves, Scarpa, Mr. Bell, and Dr. Edmonstone, to which may be added the authority of Dr. Plenck, who has two distinct varieties under the names of ophthal * Nat.

It should at the same time be observed that some very respectable practitioners still entertain doubts upon the existence of a variety produced by any such means; and are inclined to ascribe the disease, whenever it occurs, to a conveyance of the virus of the organ primarily affected to the eye, by means of the finger, or of a handkerchief. These doubts, how- ever, appear to be founded rather on hypothesis, and an indisposi- tion to believe that the conjunctive tunic ever secretes mucus, or that there is any such thing as a consent of parts between the re- spective membranes before us, than on any actual disproof. The variety seems to be supported by incontrovertible experience: and M. Scarpa has pointed out a striking difference between the trans- fer of gonorrhoea to the eye by a consent of parts, and the infection of this organ by an accidental communication of its virus ; the dis- ease being in the latter case always far milder than in the formerj I was lately consulted by Mr. G. of Great Russell Street, who had been long labouring under an ophthalmy that had assumed a chro- nic and less violent character, and which appeared to be very much of the present variety. His former life had been irregular : and he had twice before had a clap suddenly cease upon a severe inflamma- tion of the eye. I had no reason to suppose that the present inflam- mation was the result of such a transfer; but as he had been for some weeks attended by a surgeon of considerable eminence, who had already exhausted, although in vain, nearly the entire treasury of medical resources, I could not avoid observing that as there ex- isted so close a sympathy between the mucous membrane of the eye and that of the urethra, probably the most speedy and effectual means of carrying off the present inflammation would be some acci- dental irritation of the urethra. No steps were taken to effect this; and I was, therefore, the more astonished at finding about three days afterwards that such an irritation had accidentally occur- red, accompanied with a considerable flow of purulent fluid from the glans: and 1 was peculiarly pleased to find that from this time the ophthalmy began to diminish, and that a complete cure was ef- fected in about a week. In the third variety, or that marked by regular intermissions, the inflammatory symptoms are less violent than in either of the pre- ceding. Its cause is uncertain: and it has been suspected by some writers to originate in a particular kind of marsh-miasm operating upon a particular diathesis; and by others to be connected with a syphilitic taint. It is the ophthalmia periodica of Plenck. The cure is to be attempted during the interval; in which a free exhibition of bark has been usually had recourse to, though where a vitiated habit is suspected, sarsaparilla, or the inner bark of the elm in de- coction, or the solution of arsenic might be tried with a better chance of success. The fourth variety is called by Mr. Ware the purulent oph- GE. VIII.-SP. III.] SANGUINEOUS FUNCTION. 285 thalmy of new-born children,* and is at times as rapid and alarm- ing as the Egyptian ophthalmy. Its common cause is cold; though as it occurs far more generally in particular seasons of some years than of others, it is highly probable that a peculiar temperament of the atmosphere may form a predisposing cause. It usually makes its appearance within the first week or fortnight from birth. The eye-lids look red, and swell rapidly to such a size that it is difficult to separate them without pain. A discharge of a yellow purulent fluid soon succeeds, which, upon opening the lids, will be found to cover the entire globe of the eye. And from the forcible pressure of lid against lid, both are greatly thickened, and not unfrequently everted. The disease is usually unconnected with any other dis- order; though Mr. Ware informs us that it is occasionally accompa- nied with eruptions on the head and other parts of the body; and sometimes with signs of a scropulous constitution. At the moment of writing this, two infants of highly respectable families, and who have had every possible attention paid to them, living not many doors from each other, are just recovering from an attack, which seized them about a fortnight after birth. The dis- charge of pus or purulent matter was prodigious from each ; both the eyes of both infants were in great danger: three of the four eyes were ulcerated on the cornea on the third or fourth day, and in one of the eyes the ulceration spread so completely over the pupil, as entirely and irrecoverably to destroy the sight. Much of the best medical and chirurgical advice that this metropolis can af- ford, including that of ophthalmic surgeons, was had recourse to in either instance. The author was one" of those consulted in the one case, and was privy to the proceedings in the other. I cannot say that either in these or in any other instance that has fallen within my own range of practice, I have seen all the benefit from the use of Bates's powerful, but stimulant astringent, known by the name of aqua camphorata, which Mr. Ware ascribes to it. 1 have known it, at times, check the discharge, but do almost as much mischief from the pain it excites, and the irritation produced by very long fits of restlessness and crying, which is sure to follow. In consequence of which, moreover, neither the mother nor the nurse can summon fortitude to use it half so often or half so effectually as they ought: and even on this account alone, I have sometimes been compelled to relinquish it. Yet, even where it has had a fair trial, I have not generally found it successful. In most of the cases, however, related by Mr. Ware, the inflam- matidn was less violent than iu those just adverted to, and had con- tinued for some weeks, and assumed a chronic character: and un- der such circumstances, this pungent application may certainly be had recourse to with more propriety, and a fair expectation of benefit. , * Remarks on the Ophthalmy, Plorophthalmy, and purulent Eyes of new-born Infants.

The plan that has proved most effectual, in my own course of ob- servation is, to syringe the eyes thoroughly, so that the whole of the purulent discharge may be washed out, with a solution of alum in water, in the proportion of not less than a grain to an ounce: to continue this syringing three times a-day, to keep the bowels open, scarify the gorged vessels of the conjunctiva where it can be done, apply leeches to the temples and surround the forehead and temples lightly and loosely with folded linen, wetted with a lotion of an ounce of the liquor ammoniae acetatis mixed with seven ounces of water, and kept cold in a bucket of ice. The child, in order to re- ceive the full benefit of the solution of alum, should have its head laid flat between the knees of the operator, with the face uppermost: the lids should be separated from each other by the fingers, or if ne- cessary, as it almost always is, by the assistance of a blunt silver spa- tula, or some other blunt instrument, and the point of the syringe loaded with the astringent lotions should then be introduced be- tween them, and convey its contents all around; the syringing be- ing repeated till the whole of the collected matter is washed away. The pain produced by the use of this solution is trifling, and the child ceases to cry almost as soon as the operation is over. If, when the inflammation begins to subside, an ulcer is detected on any part of the cornea, and especially if it be over the pupil, a solution of nitrate of silver, in the proportion of a grain to an ounce of water, should be dropped into the eye night and morning after the syringing is over, and the eye be kept Open for about half a mi- nute, so that the solution may not be wiped away suddenly by the closing of the lids, but may fairly lie upon the ulcer and float over it for this period of time. Extract of bark should also be given dis- solved in a small quantity of water, to as great an extent as the in- fant can be made to swallow it; and if looseness be produced, it should be checked by a drop or half a drop of laudanum in each draught. Prussiate of potash is also a very good astringent for con- tracting the area of the ulcer, and expediting the healing process; and may be used instead of the solution of the nitrate of silver iq the form of an ointment, by means of the unguentum cetacei. By a careful perseverance in this process I have not only seen ulcera-? lions on the cornea heal speedily, but in one or two instances, with- out leaving any cicatrix to impede the vision, even where the ulcer ration has been seated over the pupil.

THE INFLAMMATION CHIEFLY SEATED ON THE TARSUS, OR EDGES OF THE EYE-LIDS ; ITS SEBACEOUS GLANDS SECRETING A VISCOUS AND ACRID FLUID THAT GLUES AND ULCERATES THE EDGES, AND IRRITATES THE EYE. Thts is the psorophthalmia of Plenck and Mr. Ware; and consists in an inflamed state of the small sebaceous glands, whose ducts ar- ranged in a row on the edge of each eye-lid, pour forth a viscid matter that incrusts and hardens; and, during sleep, when the lids have been for some time in contact, glues them together so firmly, that they cannot be separated without many a painful effort. This matter, instead of being mild and lubricant, as in health, is now not only viscid but acrimonious and erosive ; whence the eye is irritat- ed, and the edges of the lids ulcerated; and the complaint is apt to become chronic, and will sometimes last for years, or even for life. The disease is not unfrequenfly produced by small pox and measles; occasionally by a taraxis or common lachrymose ophthal- my from cold or any other causes, and in a few instances, though rarely, from a sty. Sometimes it appears to be the result ofaschro- phulous or venereal taint. It is best attacked, and perhaps only to be cured by such local stimulants as may excite a new action or inflammation that may be more manageable. The practice of M. St. Yves was here very bold; he touched the ulcers on the edge of the eye-lid with lapis infernalis, and thus cauterized the morbid surface. The unguen- tum hydrargyris nitratis, or the older form entitled unguentum hy- drargyris oitrati, has of late been used with equal success, and with far less danger of injuring the ball of the eye ; and if the inflamma- tion have spread from the tarsus to the ball itself, this also may be illined with the same application. The. best way of using which is not that of a pencil-brush, but of letting a drop of it fall into the eye, melted for the purpose in a small silver spoon held over a can- die. Or a drop of spirits, as vinum opii, ether, or Riga balsam may be allowed to fall into the eye in the same manner, and be repeat- ed daily. 287 288 HJEMATICA. [CL. HI-OR. II. SPECIES V.

The upper or lower tarsus everted, and the Everted eye-lid. conjunctiva exposed, and turgid, with red vessels. The blood-vessels visible in that part of the conjunctiva which covers the inside of the eye-lids, are far more numerous than those observable in that part of it which covers the globe of the eye. And hence the reason that in various species of ophthalmy the interior of the eye-lid is peculiarly apt to become turgid, and very highly inflamed ; and, from turgescence, thickens at its edges, and is often so considerably everted as to expose a very large portion of the conjunctiva. And if these effects of inflammation be not duly attended to, both the thickening and eversion are apt to remain and become' permanent; nor is this all, for the exquisitely tender membrane of the eye-lid, constantly exposed to irritation from cold, sharp winds, dust, a strong light, and excoriating tears, increases in tenderness, is never free from some degree of inflammation, and at length becomes highly vascular, florid, and carunculate, and exhibits a very hideous deformity; the inverted eye-lid sometimes adhering and being cemented to the cheek by abrasion and the inosculation of new vessels. The disease, under both varieties, is the result of debility. In the commencement of the simple blear-eye or vascular turges- cence, the vessels should first be scarified with a lancet so as to be disgorged of the blood with which they are loaded; and it will be sometimes expedient to repeat the scarification several times, for the operation itself produces a new and more healthy action, and gives a disposition to contractility. The edge and interior of the thickened tarsus should then be attacked with gentle stimulants and astringents ; as cold or ice-water, a solution of alum, zinc, lead, or camphor; illinations with the best brandy, vinum opii, or the nitric oxyde of mercury, in the form of the college ointment, or any GE.

Repeated blisters to the temples have also been very generally recommended; but I have frequently found them entirely ineffectual. Where additional secretion from a neighbouring organ is desirable, it may be obtained more successfully by the use of the thymalaea Monspe- liaca, or spurge-flax, the daphne Cnidium of Linneus. Small circu- lar pieces of its bark, soaked for about an hour in vinegar, may be applied to the temple of the affected side, and renewed every ten or twelve hours. It excites a serous discharge, and consequently produces increased action without blistering or irritation. The second variety, or everted eye-lid, is only to be cured by a surgical operation. Professor Scarpa was in the habit of destroying the conjunctiva at the edge of the tarsus with caustic; and, where the disease had made a greater progressf of extirpating the whole fungus close to the external muscular substance of the eye-lid, with the curved scissors: and Mr. Ware* pursued the practice in many cases with success. But where the eversion is considerable and the tarsus much elongated, a simple excision of the prurient growth is rarely sufficient to effect a radical cure ; and M. Scarpa himself, has admitted as mach by regarding such cases as almost incurable. The ingenious plan proposed by Sir William Adams, seems, however, to have triumphed over even this difficulty, and to have succeeded in some of the worst and most obstinate cases. It consists, first, in removing^ the whole of the fungous growth, by a small curved bistoury, next, in stripping away a piece of the edge of the tarsus in the form of the letter V; afterwards in separating the eye-lid from the cheek whenever it adheres to it; and, finally, in support- ing the lid, now raised into its proper place, and confining the edges of the cut eye-lid, brought in a state of juxta-position, by a proper bandage.t The divided edges heal by the first intention ; and the cure is often completed in a fortnight, with a restoration of the eye-lid to its healthy form. An inversion or entropium of the organ is sometimes produced from a contraction of its internal membrane in consequence of a cicatrix, or from other causes.J The hairs of the eye-lashes prove a great source of irritation : but the disease may be removed by some of the means just described. * Remarks on the Ophthalmy, &c. p. 40. t Practical Observations on Ectropium, i&rc.

INFLAMMATION OF THE MUCOUS MEMBRANE OF THE FAUCES, OFTEN EX- TENDING TO THE BRONCHIA, AND FRONTAL SINUSES ; INFARCTION OF THE NOSTRILS ; SNEEZING J AND, FOR THE MOST PART, A MUCOUS EXPECTORATION, OR DISCHARGE FROM THE NOSE. Catarrh is a Greek compound, and imports " defluxion," from kxvx, denoting, as stated in the table of significations to the affixes and suffixes of medical terms in the Nosology, " augmented action," and feu, " to flow." Catarrhus, however, like ophthalmia, has been used in various senses and latitudes by different authors. Schneider and Hoffman show a disposition to extend it to inflammation of the mucous glands in general; and Parr, enticed by such an example, has made it a genus for including not only what is commonly under- stood by catarrh, but the cough of old age, (which he admits is without pyrexy,) croup, dysentery, phthisis, cystirrhoea, leucorrhoea, gonorrhoea, and one or two others. This is the widest acceptation of the word. The narrowest is that of the old pathologists, who thus distinguished between three separate terms which are now regarded by many writers as synonymous : Si fluit ad pectus, rlicatur rheuma Catarrhus ; Ad fauces, Bronchus ; ad nares, esto Coryza. This couplet is, perhaps, founded upon Galen's account of these affections; but it does not follow up the Greek distinction into all its ramifications ; for the Greek physicians, as Galen himself tells us, had also a further supply of names for the defluxion when it fixed itself chiefly in other parts of the neighbourhood'; as acinus, when the uvula was the seat of affection; antiadje, when the tonsils; and paristhmia, when the attack was common to the fauces. For all these Celsus employs the Latin term gravedo, between which, how- ever, and coryza he observes that there is a manifest difference. It s this difference which I have endeavoured to support in the present system; in which coryza, treated of under our second class, as an affection of the vocal avenues, is made to mport nasal defluxion without pyrexy. Celsus takes no notice of the term catarrh ; for in his day catarrh was changed by the later Greek writers into catas- TAGMUS. Sauvages has only deviated from the rule contained in the above Latin couplet by omitting bronchus and employing catarrhus in its stead, and rheuma in the stead of catarrhus ; so that with him rheuma GE. IX.] SANGUINEOUS FUNCTION. 291 imports a cold, or febrile defluxion of the chest; catarrhus, the same affection of the fauces, and adjoining organs; and coryza, the same malady of the head or nostrils. Cullen has regarded rheuma, coryza, bronchus, and catarrhus as synonymous terms, scarcely indicating varieties of the same disease. The arrangement of Dr. Cullen, moreover, did not allow him to place bex, tussis or cough, any where else ; and being obliged to yield to the force of necessity, he has made cough also a synonym of catarrh, and has treated of it under this genus. It is here the present system differs from Dr. Cullen, as it does likewise in sepa- rating coryza from the list of phlogotic affections. Cough is not necessarily a pyrectic or inflammatory disease, though it may be occasionally a symptom of such disease. Cough therefore, under the Greek term bex, we have already considered as well as coryza, under the second or pneumatic class ; where they will probably be allowed by most nosologists to occupy more correct and natural posts than in the present place. Catarrh, thus explained, embraces the two following species : 1. COMMUNIS. COLD IN THE HEAD OR CHEST. 2. EPIDEMICUS. INFLUENZA. Under neither of these species can catarrh be regarded as a danger- ous or very serious disorder, unless neglected or treated improper- ly ; or unless it occurs with great severity in persons of delicate lungs or possessing a consumptive diathesis ; in all which cases its result may be very mischievous, and lead on to pneumonitis, bron- chitis, phthisis, or dropsy of the chest, though in itself, and separate from such concomitants, by no means alarming.

This is the pose of old English writers, a term precisely synonymous with the gravedo of Celsus, which is also employed in the earlier medical works of our own country. To pose is still used in the sense of to stupefy, and the real meaning of posie is a " narcotic charm," and hence a nosegay of tranquillizing odour inducing repose or sleep. The common symptoms of this species are a sense of fulness in the head, and of weight over the eyes, which are inflamed and lachrymose.

The voice is hoarse, the fauces sore, and the lungs loaded, often producing a troublesome cough. Its usual cause is suppressed perspiration from cold; whence Dr. Cullen conceives that cold is the constant and only cause, and would in every case be detected to be such, were men acquainted with, and attentive to the circumstances which determine cold to act upon the body. From the similarity between the fluid exhaled from the skin and that from the lungs, he conceives, that, whenever the former secre- tion is obstructed in its flow, it is transferred to, and passes off with the latter; the cough being produced by the stimulus of the increas- ed action, and exhalation.

H. contagions and miasms are often identic or nearly so, the former may be brought forward as abundantly confirming the same view. This identity, or approach to identity, between contagions and miasms, is closely connected with the present subject, and must be a little examined into for its clearer elucidation In treating of the origin and laws of febrile miasm, we observed, that it is of two distinct modifications, or proceeds from two distinct sources :* that in its ordinary course, it first appears as the result of a decomposition of dead organized matter operated upon by the common auxiliaries of putrefaction : but that aiterwards, "dur- ing the action of the fever thus produced, the effluvium from the living body is loaded with miasm of the same kind, completely ela- borated as it passes off, and standing in no need of the decomposi- tion of the effluvium for its formation ; under which form it is com- monly known by the name of contagion." 1 may now add, that as primary febrile miasm is not the only mi- asm generated in the atmosphere, so it does not seem to be the only miasm that gives rise to contagion : that both are very numerous in their kinds, and that specific contagions are, though perhaps not always, yet far most generally, a result of specific miasms produced as above. This seems especially to be the case in respect to influ- enza ; for though most individuals labouring under it are evidently affected from an atmospheric taint, many, as we shall show present- ly? appear, as in the case of remittent or typhous fever, to receive it from personal contagion: nor is there, in fact, any reason why a puriform discharge from the mucous membrane of the nostrils may not be contagious, as well as a puriform discharge from the mucous membrane of the eye-lids in opthalmy, or from the urethra in ble- norrhoea, or, as we shall shortly have to notice, from the rectum in dysentery. Among dogs and horses we perceive the same disease, in many instances highly and extensively contagious, and accompani- ed with so violent a degree fever as to be peculiarly dangerous, es- pecially to the young of these kinds. In South America, in parti- cular, this affection is so violent that half the dogs pupped there are supposed to die of it while sucklings. Whence in common lan- guage it is called emphatically the distemper, though vulgarly the snaffles, or rather snuffles, from the state of the nostrils. In nosolo- gy it is commonly called catarrhus caninus. Generally speaking, specific miasms and contagions capab't of affecting one kind of animals, are incapable of affecting any other kind; or at least rarely extend their influence any further. In a few febrile pestilences, quadrupeds and birds seem to have been fellow-sufferers with mankind, as we have already had occasion to notice under epanetus malignus, or malignant remittent fever. But this is not common ; and in some instances is well known to have depended upon the general dearth of a country, or the insalubrity of the preceding harvest. A few of the exanthems, as cow-pox, arc * Class n. Ord. I.—Remote Cause of Fever. GE. IX.-SP.

When a putrid fever has broken out among a ship's crew, the live stock has never been known to suffer from it: and it has happened occasionally, when large numbers of sheep and hogs have been stowed in a ship for the purpose of exportation, sometimes the former have been at- tacked with infectious fever, and sometimes the latter; but the sheep have never communicated it to the hogs, nor the hogs to the sheep, nor either of them to the ship's crew. " It seems to be a general law of nature," observes Sir Gilbert Blane, " at least among the mammalia, that accumulation and stagnation of the exhalations of the living body produce disease. The glanders of horses arise only in large stables, and the distemper of dogs in kennels. During the American war, it was proposed to send live sheep from England across the Atlantic. In a few weeks, in consequence of being crowded in a ship, they all died of a febrile disorder."—" In the ex- pedition to Quiberon in 1795, several horse-transports had their hatches shut for a length of time in a storm, by which means eight horses were suffocated. Those which survived became affected with the glanders soon after they landed. Professor Colman saw twenty of them under this disorder; a considerable number had been previously destroyed.* It does not appear that in either of these instances, the respective disorders were communicated from one genus or species of animals to another. That the catarrh before us possesses not only an epidemic charac- ter, but is dependent on atmospheric influence, is established b^ such a cloud of well known proofs, that it is hardly worth while to give examples. Of a dozen persons in perfect health in the same room, ten have often been attacked as nearly as possible at the same time. In the influenza of 1782, three families, consisting of seven- teen persons, arrived on the same day at an hotel in the Adelphi all in perfect health. The next day they were all affected with the symptoms of the reigning disease.! In an hospital, containing a hundred and seventy persons, more than a hundred were, on one occasion, attacked within twenty-four hours ; and few of the remain- der escaped afterwards. We have said, however, that the middle-aged, the strong, and the robust are affected soonest, and suffer most severely, while the young and the old are less susceptive of its influence. In proof of this, we may advert to the fact, that healthy and well disciplined soldiers suffer peculiarly. In 1782, this was especially the case at Aber- deen : at Dublin there were, at the same period, seven hundred soldiers confined under it in their barracks at once, and incapable of doing their duty ;| while at Utrecht the number amounted to not less than three thousand.

[<*• m.-c-R. « dred boys in Christ's Hospital, during the same epidemy, only four- teen had the disease, and all of them in the slightest manner. The proofs of communication by personal contagion are not less decisive. " The first," says Dr. Hamilton, describing the influenza of 1782, "who were seized with it at Norwich, were two men lately arrived from London, where it then continued to rage. A Serjeant of grenadiers in the 10th regiment of foot went to London on furlough : the disease then raged in the capital. He returned, in a few days, to St. Albans, affected, and communicated it to the people in whose house he had his billet. This was the first of its appearance there : and from thence it spread rapidly all over the town."! Dr. Cullen, in his Synopsis, has followed the more striking re- turns of influenza from the fourteenth century down to the present times ; or rather from the Cronica Meteorologica Toscana of 1323, by Targioni Tozzetti to Saillant's Tableau des Epidemies catarrhales. ""in all these instances," says he, " the pbaenomena have been much the same; and the disease has always been particularly remarkable in this, that it has been the most widely and generally spreading epidemic known. It has sehlom appeared in any one country of Europe, without appearing successively in every other part of it." And, in some instances, the infection has passed the Atlantic with little or no remission of its severity, and attacked Americans, who had not had the slightest intercourse with Europeans. And hence we are capable of tracing it at sea as well as on land. In the epidemy of 1782, Lord Anson sailed in the month of May with a fleet for the Dutch coast; and admiral Kempenfelt for that of France. The crews of both fleets were well on sailing: but in the same month both were attacked very generally, and the latter was obliged to return home. The previous state of the air, with respect to any of the sensible qualities of heat, cold, electricity, or damp, seem to have exercised but little power. Influenzas have recurred at every different season, in every state of the barometer, thermometer, and hygrometer. Thus the influenza of 1762, one of the severest on record, pro- ducing effects which continued, in many instances, for two or three years afterwards, was preceded by weather uncommonly warm; while in that of 1767, being the next in rotation, which was also very severe though productive of less durable mischief to the con- stitution, the weather was remarkable for being unusually cold.J We know nothing of the country from which the disease has at any time taken its rise; but it has frequently seemed to proceed from north to south, though it has occasionally travelled from west to east. That of 1781 and 1782 is said to have originated in China, and to have travelled through Asia into Europe ; whence it crossed • .Med. Trans. Vol. HI. p. 56. t Mem. Med. Soc. of Loud, ut supra.

If we allow its materies to depend un*>n specific miasm floating in the atmosphere, we can only ac- count for its preserving its agency so long, and operating in such distant theatres, by supposing that its particles are with great diffi- culty dissolved or decomposed in the air, even when in its purest state or highest degree of agitation by tempests. Of the specific miasms we are a little acquainted with, some seem to dissolve or lose their power much more readily than others, and hence spread their in- fluence through very con'iaed peripheries ; while others are only dissoluble in a pure atmosphere, and consequently retain all their virulence in an air already saturated with other foreign elements : properties which the author has already endeavoured to exemplify and illustrate in the inquiry into the Remote Cause of Fever.* The chief influenzas that have visited Europe within the last three centuries, occurred in the following order of time : 1510; 1557; 1580; 1587; 1591; 1675; 1709; 1732-3; 1743; 1762; 1767; 1775; 1781 and 1782 : since which period the return of the disease has been little noticed in respect to extent or violence. The remedial treatment need not detain us long, notwithstanding the violence with which the disease makes its assault. Bleeding, as we have already observed, is rarely required, and, from the de- bility so soon induced, should be avoided, except in urgent pleuritic pains, which are not common. It was tried copiously by many practitioners in 1782, but they soon reverted to the cautionary track of Sydenham. Quiet, diluent drinks, and the promotion of that easy breathing perspiration which Chenot has distinguished by the name ofdipnoe, will usually be found sufficient, if the bowels be kept free from confinement. If the chest be much loaded, an emetic will af- ford the best relief. And if the cough be troublesome, and the breathing laborious, both which, however, are generally alleviated by an emetic, small doses of ipecacuan, with or without oxymel of squills, will promote an easy expectoration, and take off the sense of oppression. Dr. Cullen joined these with opium, and was particu- larly attached to the use of Dover's powder in all catarrhal affec- tions, asserting that there is no disease in which opium has been found more useful.! But it generally agrees better in common ca- tarrhs than in influenza. The subsequent debility may be removed by a free use of the bark, gentle exercise, pure air, cold bathing, and a liberal regimen : which last, indeed, should be continued through the disease itself. The cough, occasionally produced, re- mains sometimes as a sequel, long after the other symptoms have disappeared: an.I, in this case, opium with camphor, or the resi- nous balsams, often affords essential relief, and especially at night; yet it has not been found that even the symptom of a cough has proved any impediment to the use of the bark, or even to that of * Vol. n. p. 53.

From the mixed character of this malady there is some difficulty in fixing its exact place in a nosological classification. The severe local symptoms give it a close affinity to the enteric diseases ; while the fever that is so general, though not a constant concomitant, of- ten most alarming from its violence and malignity, and frequently assuming a remittent character, seems to mark it for some order in the pyrectic class. There is also another discussion to which dysentery has given rise, and which has sometimes been conducted with considerable warmth. When it is accompanied with a high degree of fever, and a copious discharge of mucous, bloody, membranous, or filmy mat- ter, it is admitted on all hands to be contagious, though it has been debated whether the matter of contagion is thrown forth from the body of the sick, or from the putrescent recrements. But the grand question that has been agitated is, whether dysentery ever exists without contagion? or, in other words, whether, when the disease exists without those virulent symptoms which are clearly indicative of contagion, it is entitled to the name of dysentery? Dr. Cullen, who, if he did not first start this controversy, has fol- lowed it up with a more peremptory opinion than perhaps any other writer, has contended for the negative of the question ; and has hence not only arranged the disease under his class pyrexiae, but generically distinguished it by the character of pyrexia contagio- sa : asserting, in his Synop>is, that he has never met with more than one species; and still more distinctly in his First Lines, that " the disease is always contagious," and that the contagion is proba- bly at all times specific* Dr. Parr andDr. Young make a nearer approach to the general ;* Part i. Book v. Chap. n. Sect, mlxxv. (SE. X.] SANGUINEOUS FUNCTION. 301 opinion of Dr. Cullen than any other nosologist I am acquainted with. They regard the disease as an inflammatory affection; but seem to differ from Dr. Cullen in believing it to be essentially and at all times contagious : the former limiting himself to the expres- sion that it is generally so ; the latter, that it is often so. The earlier nosologists, however, have laid little or no stress on either the pyrectic or the contagious character of the disease; and hence in Sauvages, Linneus, Vogel, Sagar, and Macbride, it occurs as a genus under the division, not of fevers but of fluxes, without any notice of fever or contagion except as a distinctive symptom in some of their species. In these circumstances we cannot do better than turn back our footsteps to the minute and accurate description of Sydenham, and take him as our pole-star: under whose clear guidance we shall seldom fall into error, and whose view of the subject has best har- monized with whatever degree of practical information has fallen to my own share. In the running comment to this disease, contain- ed in the volume of Nosology, I have endeavoured from a careful perusal of all his writings that relate to the subject, to give a brief summary of his history of dysentery, and the arrangement under which he had contemplated it from year to year ; and as this sum- mary cannot well be further curtailed, I must beg leave to quote it as it is there written. " In the year 1662," says he, " cholera, dry gripes, or colic with- out stools (immania ventris tormina sine dejectionibus,) and dysen- tery, were very frequent. In the following autumn the last two dis- eases returned ; and in the midst of their raging appeared a new kind of fever (novum febris genus) which accompanied both dis- eases, and not only seized those that were afflicted either with the one or the other, but even those that were free from each; resem- bling the fever that not unfrequently (non infrequenter) attended the ' two preceding diseases, and which was hence distinguished by the name of febris dysenterica." Omitting the consideration of the tormina or gripes, we here meet with a brief account of, 1. simple dysentery, or without fever ; 2. dysentery complicated with the fever that not unfrequently attend- ed it; and 3. a new fever resembling this last. And we also find that simple dysentery, or that without fever, may at times be epi- demic or contagious, as well as that with fever. The foregoing passage, however, forms only the opening of the first chapter. It is in the third that this admirable observer and excellent writer enters fully into a description of the epidemical dysentery of the period before us; in which he tells us, that in the course of the autumn of 1669 the dry gripes (ventris tormina sine dejectionibus) and dysenteries raged nearly equally; and that sometimes a fever accompanied them, and sometimes not:" febris nunc iis acces-it, nunc aberat. " At times," says he, " the dysente- ry commences with rigor and shivering, succeeded by a heat of the whoie body, as is the case in fevers—but frequently there is no ap- 302 HiEMATICA. [CL. IH.-< pearance of fever, for the host of gripings take the lead, and the de- jections follow." He pursues his description of the simple dysentery, or that without fever, observing that in this species an excrementi- tious stool is sometimes interposed without considerable pain; and then enters upon the species accompanied with fever. " In the mean time," says he, " if the patient be in the vigour of life, or have been heated by cardiacs, a fever arises, his tongue is covered with a thick white mucus, and if he have been much heated, it is black and dry; there is great prostration of strength, exhaustion of spi- rits, and every symptom of an ill-conditioned fever." It is not necessary to pursue his description of this second species further. It must be obvious to every one, that, in the opinion of Sydenham, dysentery, as a genus, embraces at least two distinct species, both of which, at the period of his writing, were epide- mic ; the one of a milder nature without fever, the other of a ma- lignant nature with it. The former of these is often met with in private practice, of spo- radic origin, and without evincing any contagious character. The latter is perhaps, as Dr. Cullen asserts, at all times contagious. Since writing the above, the author has met with Dr. Harty's " Ob- servations on the Simple Dysentery and its Combinations, contain- ing a review of the most celebrated authors who have written on this subject:" in which much of his own opinion is confirmed, and copiously illustrated. It is only necessary to observe further, that though there may he, at times, no contagion, and little or no fever, there seems to be al- ways some degree of inflammation in the colon or rectum, occasion- ally perhaps extending higher; an inflammation of a peculiar kind, with a strong tendency, when violent, to run rapidly into a state of gangrene ; but, when milder, exciting that increased flow of mucus, which is common to the inflammation of all mucous membranes, and which is especially conspicuous in ophthalmy and in catarrh. On this last account it appears to me that the proper nosological place for dysentery, as a genus, is immediately after these two diseases; though, from too close an adherence to the concurrent arrangement of the earlier nosologists, it will be found placed, in the physiologi- cal synopsis, under the order enterica of the class Cceliaca, a posi- tion which 1 now beg the reader to correct. The febris nova or dysenterica of Sydenham seems hardly entitled to consideration as a distinct species. It was the common epidemy of the season, accompanied with or succeeded by a few of the slighter symptoms of dysentery, without the pathognomic evacua- tions. Putting this, therefore, out of the question, dysenteria, as contemplated by this great writer, and as confirmed by the general experience of the present day, seems to include the two following species: 1.

FEVER SLIGHT OR UNPERCETVED ; THE FECES, WHEN DISCHARGED, EVA- CUATED WITHOUT CONSIDERABLE PAIN, OF A NATURAL QUALITY AND AFFORDING EASE. The atmospheric temperaments chiefly calculated to produce severe bowel complaints are those of summer and autumn; when the liver is excited to a larger secretion of perhaps more pungent bile, from the greater heat of the weather ; the skin is exposed to more sud- den transitions from free to checked perspiration; and the exhala- tions that rise so abundantly from marshes and other swamps too often give an epidemic character to the atmosphere, and lay a foundation for intermittent and remittent fevers. We have here sufficient ground for local and general affection, and may readily see how it is possible, from the operation of one of these causes singly, or of two or all of them jointly on an irrita- ble state of the intestines, for all or any of the local symptoms to be produced which enter into the generic or specific definition of the disease before us; as also how it is possible for these symptoms lo be combined with fevers of various kinds and various degrees, so as to render the complaint peculiarly complicated and dange- rous ; though we have not yet been able to find out what are the precise causes that, operating locally, produce the distinctive symptoms of dysentery Tather than those of diarrhoea, cholera, or any other irritation or spasmodic action of the intestinal canal. This may, perhaps, sometimes depend upon idiosyncrascy, some- times upon accident, and, in the severer cases, upon contagion or a specific miasm. The symptoms, however, already noticed sufficiently point out the general seat of the disease ; the tormina or griping pains, the region most affected by them ; and the costiveness or nodules of feces that arc dejected, the existence of spasmodic constriction in or about the colon or the upper part of the large intestines. And while such is the state of the canal above, the excessive straining or tenesmus, accompanied with a discharge of simple or bloody mucus, shows, as distinctly, the existence of great irritation in the sphincter and its vicinity. In some cases one of these parts is more affected, and in some another; and hence the origin of the dispute concern- ing the precise spot of the disease, which Stoll places altogether in the colon,* and other writers in the rectum ;t while Piso contends v Nat. Med. Part. hi. p. 294—826. t Cawley, Lond. Med. Journ. 1786. 304 I-OEMAT1CA. [CL. III.-OR. II. that the liver is always affected, and indeed the organ principally concerned;* reasoning from the bloody or atrabiliary dejections that are a symptom in the severer cases. That the irritation existing in the larger intestines may occasion- ally extend to the mouth of the hepatic duct, and produce a sym- pathetic excitement in the liver, is highly probable; and indeed appears obvious from the increased flow of bile, often of a deeper colour, that sometimes accompanies the dejections, in the remis- sion of the spasmodic constrictions, and points out some alliance be- tween this disease and cholera; both which, as Sydenham has suffi- ciently shown, in certain seasons co-exist as epidemics. But a mere increased secretion of bile cannot readily be contemplated as the proximate cause of dysentery; for its usual effect is to quicken the natural motion of the intestinal canal, and to produce looseness rather than constriction. How far any other irritant, as putrid vapours, crude fruits, or acrid food, accidentally introduced into the intestines when under a state of peculiar morbid sensibility, which it seems necessary to pre-suppose, is capable of exciting dysentery, may perhaps admit of a doubt; though we have no reason to conceive that any such irritants are a common cause. And still less can we concede to the hypothesis of the Linnean School, that the disease is produced by the larves of a species of tic or acarus, which the Swedish natu- ralist has too hastily introduced into his classification under the name of acarus dysenteriaz: and which Rolander, who laboured un- der repeated attacks of this affection while residing with Linneus, pretended to trace from water deposited in a cistern of juniper- wood.t The ordinary exciting cause of simple dysentery, there can be little question in the present day, is suppressed perspiration or a sudden chill applied to the surface, acting'in conjunction with the predisposing cause of an atmosphere varying rapidly from heat to cold and from moist to dry : on which account the disease is to be found most frequently in the aestil al and autumnal months; and occasionally as an epidemic of the season. But by what means this exciting cause operates upon the larger intestines rather than upon any other cavity, or produces the symptoms of dysentery rather than those of diarrhoea, cholera, or colic, we seem to be incapable of determining. We perceive, however, in the events of every day, that sudden chills on the surface are possessed of a revellent power, and throw the action which is lost on the skin on various internal organs, and especially on cavities of mucous membranes, which, in consequence of this excitement, become inflamed, and pour forth an additional secretion. Such is especially the case in rheumatism and catarrh, both which terms are derived from the same Greek root, and import defluxion. And from this common w Discourssur la Nature, &c. des Maladies accompagnees de Dysenterie. t Amaen. Acad. v. 82 et alibi. GE. X.-SP. I.] SANGUINEOUS FUNCTION. 305 character the three diseases have by some pathologists been con- ceived to be so much alike, that dysentery has been regarded as an intestinal rheumatism by Coelius Aurelianus, Akenside, Stoll, and Richter; and is actually set down, by Dr. Parr, as a species of catarrh, in his nosological classification. The diagnostics are arranged by Sydenham as follows, after ob- serving that the disease sometimes begins with the febrile symp- toms of rigor, shaking, and a hot fit. " But frequently there is no appearance of fever; for the host of gripings take the lead and the dejections follow. The gripings are always severe, and a sort of painful descent of the bowels accompanies every evacuation. The discharges are chiefly mucous, but an excrementitious stool some- times intervenes without considerable pain. The mucous stools are generally streaked with blood; but in some cases there is no such appearance through the whole course of the disease. Never- theless, if the stools be frequent, mucous, and accompanied with gripings, the disorder may as justly be called a dysentery as if blood were intermixed with them." He afterwards observes, that, however severely the disease may make its attack on adults and aged persons, which last fall a sacrifice to it more frequently, it proves very gentle in children; who sometimes have it for several months if left to nature, and even this without inconvenience. Where the patient was of a plethoric habit, and the symptoms violent, and especially if accompanied with a pyrectic onset, the usual practice of this master of his art was to begin with venesec- tion, to give an anodyne at night, and an aperient of tamarinds, senna, and rhubarb in the morning, in the proportion of half an ounce of the first, two drachms of the second, and a drachm and a half of the third, "i prefer," says he, " the use of rhubarb in this form to giving it alone or in a smaller quantity, because unless it acts thoroughly it does not much conduce to a cure ; and because, also, though more powerful cathartics might be employed, they would but aggravate the gripings and increase the general disorder and especially the depressioh of .spirits. And hence even after the rhubarb purge, I commonly give the anodyne at an earlier hour than usual; indeed at any time in the afternoon, as soon as the laxative has ceased to operate, and thus get rid of the excitement it has occasioned. This purgative I repeat twice every other day, always following up the dose with an anodyne as above ; and I re- sort to the anodyne every morning and evening, even when no aperient is given, that I may repress the violence of the symptoms, and gain a truce while I am evacuating the peccant humour. The anodyne I make use of is sixteen or eighteen drops of laudanum in a dose of cordial-water of any kind: and after the first bleeding and purging, 1 allow any temperate cardiac to be taken occasionally in compound scordium or some other distilled water, through the whole course of the disease." For common drink he prescribed milk and water, or the white decoction, with crumb* of bread, or posset-drink; and where there VOL. II. 3f> 306 ILBMATICA. [«. ™-OR. II. was much debility, he allowed a beverage of half a pint of sack^to a quart of spring-water. The ordinary food was panada or mutton '"Dr." Sydenham's sheet-anchor, however, was his own celebrated liquid laudanum, the vinum opii of the London College, but with a much larger proportion of the narcotic: though he only preferred the liquid to the solid laudanum, as purified opium was then called, because of the greater conveniency of dividing it into doses. So at- tached was he to this medicine, and so persuaded of its permanent efficacy, that where the symptoms were more violent he increased the dose, and gave it three times instead of twice a-day, besides prescribing daily an opiate injection: while in the milder cases of the disease, or where it was but little affected by an epidemic temperament, he asserts that even the evacuating plan may be safely omitted, and the cure be more summarily performed by laudanum alone* The principles on which this mode of practice is founded, are peculiarly clear and rational: for they indicate an attempt to take off inflammatory action; to relax the spasmodic constriction which both blocks up the feces, and produces the griping pains; and to assist the discharge of the feces as the natural passage is sufficient- ly opened. Rhubarb has been objected to by Dr. Cullen and other modern practitioners on account of its astringency: but Dr. Fordyce has advocated its employment as clearing the prima? vise better than any other purgative. Its astringent effect, however, is sufficiently guarded against in Dr. Sydenham's prescription by its union with tamarinds and senna. Yet as senna is apt to gripe, even in ordi- nary cases, it ought to be less employed in dysentery than in any disease whatever; and its place may be well supplied by the neu- tral salts, calomel, or small doses of tartar emetic. In simple dysentery, opium under any form is an admirable remedy; for it not only tends to quiet the local pain* and irritation, but, by aug- menting all the secretions except that of the intestinal canal, to ex- cite a general relaxation, and make a revulsion towards the sur- face. By taking off" the spasmodic constriction, it acts, indeed, in- directly as a laxative, and in this way is alSo of great advantage. But as its immediate effect on the bowels is to constringe them, it may be very much improved by uniting it with small doses of tar- tar emetic, or Dr. James's powder; or which, perhaps, in the pre- sent disease, is stiil better, with some neutral salt and ipecacuan, as iu the admirable composition of Dover's powder. And with these few alterations it would be difficult, perhaps, to improve upon the plan laid down by Sydenham, for the treatment of dysentery in its simple and uncomplicated appearance. Under this form it is, per- haps, rarely, if ever, contagious ; but to guard against the possibi- lity of such a fact, the dejections should be removed with attentive -peed; and the sick room be large, and freely ventilated. * Sect. iv. Cap. in. passim. tage. They have indeed occasionally been given from the first; and in a few very slight cases and very infirm constitutions the practice may have succeeded; but as a general rule of conduct it is highly rash, and has rarely been tried without repentance. Some of them may have a power of stimulating the intestinal canal; or, in large quantities, this, as conjectured by Dr. Cullen, may be a power common to all of them ; but their chief virtue is that of in- creasing the tone, and they cannot therefore be employed at the commencement of the disease, when the fever is severe and the constriction rigid, without certain and essential mischief. In the decline of the disease however, we may take our choice. The simarouba has been exposed to various fluctuations of opi- nion. It was at one time regarded as little less than a specific for dysentery, and was eulogized not only in the West Indies, but in Europe, as combining the desirable qualities of an excellent tonic, antispasmodic, sudorific, cardiac, and anodyne.* This was to carry its praise too high. By Dr. Cullen it has, on the contrary, been un- justly degraded, who regards it as nothing more than a simple bit- ter ; and even in this view places its virtue below that of chamomile flowers.t Of late years, however^ it has again been rising in public estimation ; and as a truly valuable tonic, and particularly in intestinal debilities, I am pleased to see it taking a stand in the Materia Medi- ca of the London College. The cinchona is of more doubtful efficacy. It will be greatly beneficial where the disease has assumed an intermittent or a putre- scent character, but it is apt in many idiosyncrasies to irritate the bowels, and when had recourse to must be closely watched. Of the nerium antidysentericum of Linneus, formerly in high re- pute, under the name of conessi bark, as an invigorating bitter and tonic in the present and all other debilitating complaints of the ali- mentary canal,| 1 cannot speak from personal trial; but it seems to have fallen into oblivion too suddenly, and deserves a further in- vestigation. The virtues of columbo need not be enlarged upon; they are known to every one in the present day : and under every form this medicine will be found a powerful auxiliary in the hands of a practitioner^ who has judgment enough to seize the proper moment in which it ought to be employed in the progress of dysen- tery.

This genus is new to nosological classifications : but it is necessary, in order to include two diseases which have hitherto been regarded by most writers as totally unconnected, and treated of very remotely from each other; but which, though occurring under very different circumstances, are marked by the same proximate cause, affect the same organs, and demand the same local treatment. They consist of the following species : 1. BUCNEMIA SPARGANOSIS. PUERPERAL TUMID-LEG. 2. -------- TROPICA. TUMID-LEG OF HOT CLIMATES.

I have observed above, that the tumid-leg of child-birth has mostly been contemplated as a very different affection from that of hot cli- mates, and has rarely been treated of in connexion with it. Dr. Thomas, however, has been sensible of their relation, though he has still placed them at a distance from each other. The disease," says he, " to which in my opinion it bears the strongest resem- blance, (meaning the species before us,) is the glandular affection so frequently met with in the island of Barbadoes."* It is singular that, with this impression, so able a writer should still have regard- ed the latter as a species of elephantiasis, and arranged and des- cribed it accordingly. In the present author's first edition of his Nosology the ordinary arrangement was so far yielded to as to place the two species remotely, though a distinction between elephantiasis and the tumid-leg was strongly enforced. The tumid-leg of lying-in women has been described by different authors under a variety of names, as phlegmatia dolens, phlegmatia lactea, ecchymoma lymphatica, and by Dr. Cullen, as anasarca serosa ; few of which express the real nature of the affection, and some of them a source obviously erroneous. By Dioscorides it was denominated sparganosis, from oKx^yxu, " to tumefy and distend ;" lumeo et distentus sum, as rendered by Scapula; and, as the term is sufficiently expressive, it has been pre- ferred on the present occasion to any of the rest; and appropriated to the present disease, instead of being made common, as Diosco- rides has made it, to numerous other affections of the chest. By Dioscorides, and most writers till within the last twenty or thirty years, the swelling has been ascribed to a redundancy of milk, and a morbid deposition in consequence of such redundancy; * Modern Practice of Physic.

H. whence the French practitioners call it to the present day, after Pu- zos, depot laiteux, or 1 ait repandu; and the Germans milchstreichen. A minuter attention to the subject, however, has_ sufficiently shown that this complaint has seldom any connexion with the milk: per- haps never. It has occurred where the breasts have been destitute of milk, and where they have overflowed; where suckling has been relinquished, and where it has been continued. It is but very lately I was consulted by a young woman labouring under it, who was suckling her infant without any complaint of the breast whatever. It is as little influenced by the state of the lochia as by that of the milk. It attacks women of all ranks and of all habits ; the healthy and the diseased; the lean and the corpulent; the sedentary and the active; the young and the middle-aged. It also occurs at all seasons and situations; and has never been known to appear in any other part cf the body than the lower extremities. In about twelve or fourteen days after delivery the patient com- plains of pain in the groin of one side, accompanied with the gene- ral train of pyrectic symptoms, but without the precursive shivering. The part affected soon becomes swelled and distended, the swelling extending to the labia pudendi of the same side, and down the in- side of the thigh to the leg and foot; in a day or two the limb is double its natural size, is hot, exquisitely tender, and moved with great difficulty. It has not, however, the ordinary external signs of inflammation, but is hard, smooth, glabrous, pale, and equable, except where the conglobate glands are situate, which are corded and knotty, as in the groin, the ham, and the back and fleshy part of the leg. There is, occasionally, an uneasiness in the loins and in the region of the pubes on the same side. The swelling has sometimes ap- peared as early as twenty-four hours after delivery, and sometimes not till five weeks afterwards. The accompanying fever, which is of a hectic form, usually declines about the fourteenth or twenty- first day, but in some cases runs on for six or eight weeks, and the patient becomes greatly emaciated. The first appearance of im- provement takes place where the disease commenced, about the groin, the pain and tumor gradually subsiding in this quarter, and the amendment spreading in a continuous line. Sometimes, though rarely, both sides are affected simultaneously, and, in a few instan- ces, the sound leg has exhibited something, though a less degree, of the same complaint, as the diseased leg has amended. The amendment is very slow ; and, in many cases, the affected limb con- tinues weak and of a morbid enlargement through life. The latest and best writers upon the subject, Mr. White, Mr. . Trye, Dr. Ferriar, and Dr. Hull, concur in deriving the disease from some affection of the lymphatics of the distended side, though the^ differ as to the nature of such affection. Mr. White supposes it to be an extravasation from the lymphatic vessels ruptured by the pressure of the child's head against the brim of the pelvis dur- ing a severe labour-pain, the extravasated fluid not being duly ab- sorbed. Mr. Trye refers it to inflammation of the lymphatic glands: WE. XI.-SP. I.] SANGUINEOUS FUNCTION. 319 Dr. Ferriar to inflammation of the side affected generally: and Dr. Hull to lymphatic inflammation and an effusion of coagulable lymph, instead of an effusion of the proper fluid of the lymphatics, by a rupture of their coats. The last, if not the real cause, is the most plausible thus far offered. The lymphatics are capable of being strained and weakened during the progress of labour, and the in- flammation may follow from undue distention in consequence of such injury : but were the lymphatics to be ruptured during labour the disease would probably show itself much sooner than the second or third week after delivery. There is, however, another way of ac- counting for this inflammatory affection of the lymphatics of the lower limb, and which, upon the whole, I cannot but think is its real source. It is that of supposing an habitual debility in the lym- phatics affected, and inflammation produced in them, from what Mr. Hunter calls, though with some looseness of expression, the stimu- lus of relaxation: in other words, from the weakly lymphatics, now destitute of the surrounding pressure and stimulus which they pos- sessed during pregnancy, yielding too easily to the flow of the fluid they have to convey, and on this account becoming morbidly dis- tended, and inflamed in consequence of such distension. And we may hence see why sparganosis puerperarum occurs in no other limb or part of the body than the lower extremities. It is not to be wondered at that the effused fluid should exhibit a thick, glutinous, and even milky appearance: for we have had fre- quent occasions of noticing a somewhat similar secretion in the case of inflamed membranes, and even in inflammation of the heart itself; and, at the time we are contemplating, there is a general tendency in the constitution to produce genuine milk, and often in great abundance. Nothing can be more unlike than this complaint and dropsy, or than the effused fluid and serum: and hence Dr. Cullen seems not less improperly to reckon sparganosis puerperarum, a modification of anasarca (anasarca serosa,) than those who have re- garded it as a variety of milk-affection. Serous dropsy of the lower extremities occurs unquestionably at times after labour, but its symp- toms, and appearance are altogether different. There is apparently as little reason for the hypothesis of Dr. Denman, who, while regarding it as an inflammation of the lympha- tics, refers the inflammation to an absorption of some acrimonious . matter secreted by the uterus: for the disease has occurred where there has been no more morbid action of the uterus than of the mammae; and all the secretions have proceeded healthily and in their proper quantity. The cure is to be attempted first by leeches applied down the course of the limb, poppy-head fomentations, and alvine evacuants -. and afterwards, as soon as the inflammatory symptoms have a little subsided, by local stimulants, so as to excite the torpid absorbents to increased action: of which the most useful in the author's hands has been the volatile liniment with laudanum. The laudanum, on a cursory view, may seem to add to the vascu- 320 ILEMATICA. [CL. III.-OR. II. lar torpor: but it tends to take off the pain and irritation that still remains, and thus enables the tranquillized vessels the more easily to recover their tone. Yet whatever application of this kind is em- ployed, it should be accompanied with gentle friction, continued for half an hour or more, as the limb is able to bear it: for the fric- tion itself is of essential service, and tends, perhaps even more than any other local stimulant, to restore the limb to a healthy action. Mr. Trye advises, for the same purpose, the use of mecunal oint- ment ; and others, that of small doses of calomel. But neither have proved decidedly useful; while in some instances of great debility, they have evidently produced mischief. The chronic weakness is to be removed by a continuance of the friction, bathing with sea- water, or, which is much better, bathing in the sea itself, an elastic flannel bandage, horse exercise, pure air, and, if necessary, general tonics and astringents.

THE TUMID LIMB HARD, LIVID, AND ENORMOUSLY MISSHAPEN : SKIN AT FIRST GLABROUS, AFTERWARDS THICK, SCALY, AND WARTED : SUCCES- SIVELY BULGING AND INDENTED : OCCURRING CHIEFLY IN TROPICAL CLIMATES. This species is intended to comprize that singular disease, known in the West Indies, and generally over Europe, by the name of Bar- badoes-leg, from its being indigenous to the island of Barbadoes. Yet it is not in Barbadoes alone that it makes its appearance : for it is of high antiquity, as well as of very wide range in hot, and es- pecially in tropical climates; and constitutes the genuine da -fil or elephant leg of the Arabians, being so denominated from its livid, tumefied, scaly, mis-shapen appearance. As the Arabic dal or daul- fil is literally elephantiasis or elephant-leg, and as the Greeks dis- tinguished another and very different disease by the name of ele- phantiasis, the Greek translators of the Arabian writers were very generally betrayed, from the unity of the name, into a confusion of the two disorders, as we shall have occasion still further to observe when treating of proper elephantiasis under the fourth order of the present class: and the confusion has, in a considerable degree, des- cended to our own times, insomuch that many writers of the present day continue to jumble the elephantiasis, or elephant-/eg, of the Ara- bians, with the elephantiasis, or elephant-sfci/i, of the Greeks, and to describe them as a common affection, though no two complaints OE. XI.-SP. It.] SANGUINEOUS FUNCTION. 321 can be more unlike: the former being a mere local malady, produc- ed accidentally, and confined to the individual who labours under it; and the latter a constitutional disease, in every quarter heredita- ry, and in most quarters contagious. The Arabians, however, had the disease called elephant-skin, the elephantiasis of the Greeks, by themselves called juzam as well as the dal-fil or elephant-leg, the disease before us. And, as the ma- lady called leprosy, and by the Arabians beras, was supposed by many physicians, as well Arabian as Greek, to terminate frequently in juzam, or proper elephantiasis, the disease before us has occa- sionally also been confounded with leprosy as well as with elephant- skin, and all the three affections have been huddled together by many writers into one common disease. Even Dr. Schilling, a late practitioner of considerable merit at Surinam, has not escaped this last error; for he describes the tumid-leg under the name of lepro- sy ; confuses its earliest symptoms and appearance with those of the leprosy of the Greeks, and especially with those of the lepra or lepriasis canescens, and then distinguishes elephantiasis, the disorder he professes to be the immediate subject of his pen, as a peculiar branch of leprosy, merely varied by its commencing in the feet, in- stead of in any other part of the body: and, carrying on the confu- sion, he next interprets the tumid-leg, or disease before us, as a mere variety of elephantiasis.* A summary of Dr. Schilling,s publication is given in the Edin- burgh Medical Commentaries, and even the learned editors them- selves seem to have adopted his views: for the following is thoir explanation of the general subject before us : " In some instances of this disorder (leprosy,; the feet are the parts chiefly affected, and then the complaint has been termed elephantiasis, not only from the resemblance of the diseased feet to those of the elephant, but from the walk of such patients resembling exactly the step of that animal. In this species of the complaint the skin and other soft parts become wonderfully expanded, at the same time that the dif- ferent small bones swell considerably. The toes become thick, and at last melt down, and run together as if made of wax. The sligh- test affection of the diseased parts occasions a discharge of blood, which, however, is commonly easily put a stop to. The disorder by degrees spreads from the toes over the whole foot, and thence proceeds to the femur, rendering the different articulations in its course stiff and immoveable: at the same time that, in many instan- ces, the muscles and tendons concrete so firmly together that the most skilful anatomist can neither separate nor distinguish them without great difficulty."! Dr. Schilling adds, that notwithstanding the frequency of this disorder in some of the West India islands, and in some parts of the continent of America, he is clearly of opin- ion it is not a disease of those climates, but was introduced, and con- * G.

II. tinues to be supported there by an importation of negro slaves from the cojist or Africfl For a distinct and more correct account of this species, we must turn to the writings of Dr. Hillarv* and Dr. Hendy, who have judi- ciously separated it from both the leprosy and the elephantiasis of the Greek writers, and treated of it as an individual malady: the former under the name of " Barbadoes leg," and the latter under. that of the " Glandular disease of Barbadoes." It is singular how- ever that Dr. Hendy should have adopted the erroneous idea that the disease before us is not only endemial to Barbadoes, but that it is to be found no where else ; and that patients who migrate from this island for a cure, are almost sure to abtain one, unless in a chronic or inveterate stage of the disease, to whatever quarter they direct their course. It has been known immemorially in India, and is by the oriental writers, and even by Sir William Jones, justly distinguished from the juzam, which he tells us must not be con- founded with the dal fil, or swelled legs described by the Arabian phvsicians, and very common in that country. It is also indigenous to the Polynesian isles, where it takes the name of yava-skin, as being supposed to originate from drinking the heating beverage called yava; and, like the gout among ourselves, is regarded in a sort of honourable light. The tropical bucnemia, like the puerperal, is occasioned by an effusion of coagulable lymph into the cellular membrane under the skin of the part affected, in consequence of inflammation of the lym- phatics of the lower limb, and especially of the inguinal glands; the cause of which is perhaps different in different cases, but which is most commonly cold, operating upon a set of vessels peculiarly ir- ritable, and especially so when affected with inflammation in tropi- cal climates. The blood-vessels, and particularly those of the sur- face, are here also greatly, relaxed; and hence the skin, instead of maintaining the paleness of the first species, very soon becomes suf- fused with a deep red or purple hue ; while the saburral fluid, that exudes from the cutaneous exhalents, concretes, as its finer parts fly off, into rough and sordid scales, and the skin itself becomes enor- mously thickened and coriaceous. The effusion is usually preceded by a febrile paroxysm induced by the glandular inflammation just noticed; and which, from the first, discovers a tendency to recur, though often at irregular peri- ods, so as to resemble an erratic intermittent. Every fresh attack adds considerably to the effusion, and consequently to the morbid size of the limb, and exacerbates every symptom: and hence the greater severity of this species than of the former, and the mon- strous disfigurement of the leg and foot by which it is distinguished. In many instances also the inflammation extends to the surrounding as well as to the descending parts; and hence the scrotum, like the pubes in puerperal bucnemia, is often peculiarly affected and dis- * Works, Vol. i. p.

II.] SANGUINEOUS FUNCTION. 323 tended to an enormous magnitude ; while occasionally the glands of the axilla participate with those of the groin, and the fore-arm be comes also enlarged. In a few instances the disease is said to have commenced in the axilla; but such cases are very rare, and not well established. In this manner the disease at length assumes a chronic character: the monstrous size and bloated wrinkles of the leg are rendered permanent; the pain felt acutely at first subsides gradually, and the brawny skin is altogether insensible. Yet even from the first, except during the recurrence of the febrile paroxysms, the patient's constitution and general functions are little disturbed : and he some- times lives to an advanced age, incommoded only by carrying about such a troublesome load of leg; which, however, as we have noticed already, is regarded in the Polynesian isles as a badge of honour. In our own country the disease is rarely met with but in its con- firmed and inveterate state, after repeated attacks of the fever and effusion have completely altered the organization of the integuments and rendered the limb altogether incurable. In this state the distended skin is hard, firm, and peculiarly thickened, and even horny; while the muscles, tendons, ligaments, and bones, are, for the most part, little affected. In this advanced stage, the disease seems to be altogether hopeless: nor in any stage has the practice hitherto pursued been productive of striking success. This has consisted chiefly in endea- vours to alleviate the febrile paroxysms by laxatives and diapho- retics, and subsequently to strengthen the system by the bark. It would be better perhaps by active and repeated bleedings, as well general as local, and powerful purgatives, to endeavour to carry off the whole of the first effusion as guickly as possible ; and then to direct our attention to a prevention of the paroxysms to which the constitution appears to be peculiarly subject, after a single one has taken place, by prohibiting exposure to the damp air of the evening, and by the use of tonics. An original and chronic affection of this kind, in which the inte- guments of the legs were much thickened, the limbs swelled to such an extent as to prevent the patient from walking, and incrusted with such a vast quantity of brawny scurf and scales, that handfuls of them might be taken out of his bed every morning, was successfully attacked many years ago by a mistake of one plant for another. The case is related by Dr. Pulteney in a letter to Dr. Watson; and the patient, who had been recommended to swallow a table spoonful of the juice of the water-parsnep, with two spoonfuls of wine every morning fasting, was erroneously supplied with half a pint of what afterwards appeared to be the juice of the roots of the hemlock-dropwort (oenanthe crocata, Lin.) : the first dose produced such a degree of vertigo, sickness, vomiting, cold sweats, and long continued rigor, that it almost proved fatal. So strong, however, was the patient's desire of relief, that, with the intermission of one 324 H.EIUATICA.

ARTHROSIA. ^rtttttlar Enflammattou. INFLAMMATION MOSTLY CONFINED TO THE JOINTS ; SEVERELY PAINFUL J OCCASIONALLY EXTENDING TO THE SURROUNDING MUSCLES. Arthrosia is a term derived from xgipu, " to articulate," whence arthrosis, arthritis, and many other medical derivations. The usual term for the present genus of diseases, among the Greek physicians, was arthritis, which would have been continued without any change, but that, for the sake of simplicity and regularity, the author has been anxious to restrain the termination itis to the dif- ferent species of the genus empresma that have just passed in review before us; whence arthrosia is employed instead of arthritis, and precisely in its original extent of meaning. Arthritis then, among the Greeks, was used in a generic sense, so as to include articular inflammations generally. But as almost every sort of articular inflammation has, in recent times, been advanced to the rank of a distinct genus in itself, it has frequently become a question to which of them the old generic term should be peculiarly restrained. And hence, some writers have applied and limited it to gout; others have made it embrace both gout and rheumatism ; others again have appropriated it to white-swelling: * Phil. Trans. Vol. r.xn. t G. G. Schillingii de Lepra Commentationes, 8vo. Lugd. Batav. 1776. t On tlie Glandular Disease of Barbadoes. GE. XII.] SANGUINEOUS FUNCTION. 325 while a fourth class of writers, in order to avoid all obscurity and dispute, have banished the term altogether. Now gout, rheumatism, whether acute or chronic, and white- swelling, however they may differ in various points, as well of symptoms as of treatment, have striking characters that seem naturally to unite them into one common group. Gout and rheuma- tism are so nearly allied, in their more perfect forms, as to be distinguished with considerable difficulty ; and, in many instances, rather by the collateral circumstances of temperament, period of life, obvious or unobvious cause, antecedent affection or health of the digestive function, than from the actual symptoms themselves. Stoll maintains that they are only varieties* of the same disease : Berrius, that they are convertible affections. White-swelling, in oneof its varieties, is now uniformly regarded as a sequel of rheumatism, or the result of a rheumatic diathesis; while the other variety cannot be separated from the species. All these, therefore, naturally and necessarily form one common genus, and are cor- rectly so arranged by Dr. Parr. From the close connection between gout and rheumatism, Sau- vages, and various other nosologists, distinguish some of the cases of disguised gout by the name of rheumatic gout. Mr. Hunter warmly opposed this compound appellation; for his doctrine was, that no two distinct diseases, or even diseased diatheses, can co-exist in the same constitution. And, as a common law of nature, the observation is, I believe, strictly correct; one of the most frequent examples of which is the suspension of phthisis during the irritation of pregnancy. But it is a law subject to many exceptions ; for we shall have occasion, as we proceed, to notice the co-existence of measles and small-pox ; and 1 have at this moment under my care a lady in her forty-ninth year, of delicate health and gouty diathesis, who is labouring under a severe and decisive fit of gout in the foot, which is prodigiously tumefied and inflamed, and has been so for several days, brought on by a violent attack of lumbago, to which she is still a victim, and which renders her nights more especially sleepless and highly painful. I he constitutional disease has in this case been roused into action by the superadded irritation of the accidental disease ; and the two are now running their course con- jointly. It is also a striking fact that one of the severest illnesses that attacked'Mr. Hunter's own person, and which ultimately proved to be disguised gout, podagra larvata, he suspected, in its onset, to be a rheumatic ailment. The case, as given by Sir Everard Home, in his Life of Mr. Hunter, is highly interesting and curious; as showing the singular forms which this morbid Proteus sometimes affects, and the various seats it occupies; as also that a life of temperance and activity is no certain security against its attack: for xVlr. Hunter had, at this time, drunk no wine for four or five years, and allowed himself but little sleep at night. * Rat. Med. Part in. p. 122—137. v. p. 420. 326 flsmatica.

PAIN, INFLAMMATION, AND FULNESS, USUALLY ABOUT THE LARGER JOINTS AND SURROUNDING MUSCLES ; OFTEN WANDERING ; URINE DEPOSITING A LATERITIOUS SEDIMENT ; FEVER A CAUMA. The disease varies in respect to violence of the fever, and seat of the pain. The varieties, determined mostly from the last feature, are as follow : a. Artuum. Pain felt chiefly in the joints and Articular rheumatism. muscles of the extremities. C Lumborum. Pain felt chiefly in the loins; and Lumbago. mostly shooting upwards. y Coxendicis. Pain felt chiefly in the hip-joint, Sciatica. producing emaciation of the nates on the side affected, or an elongation of the limb. 5 Thoracis. Pain felt chiefly in the muscles of Spurious pleurisy. the diaphragm, often producing pleurisy of the diaphragm. The common remote cause of articular rheumatism, as of all the other varieties, is cold or damp applied when the body is heated ; though it may possibly be produced by any other cause of inflam- matory fever, where the constitution has a peculiar tendency to a rheumatic action. This tendency or diathesis seems to exist chiefly in the strong, the young, and the active ; for, though it may attack persons of every age and habit, these are principally its victims. We may hence, as well as from its symptoms, prove rheumatism to be an inflammatory disease. Even in the weak and emaciated, ob- serves Dr. Parr, the pulse is hard, the blood coriaceous, and bleed- ing often indispensable. It is an inflammatory disease, also, of the muscles, for motion is painful, the muscles are sore to the touch; and we may assume it as a position that muscular organs are alone GE XII.-SP. I.] SANGUINEOUS FUNCTION. 327 affected.* The chief pain, indeed, is usually felt in the joints ; for the more closely compacted organs, or parts of organs, though in- sensible in a sound state, are peculiarly alive to pain when diseased; the same arteries belong to both the muscles and tendons of the affected organ; and in the. latter we have reason to expect the pain to be more violent as they admit of distension with greater difficulty. How far the observation of Sir C. Wintringham is true, that those who have suffered amputation are susceptible of this dis- ease more than others,! the author cannot say from his own prac- tice ; but it is the remark of a physician who was not accustomed to form a hasty judgment. As a general rule it may be asserted that rheumatic inflammation does not tend to suppuration. In a few rare instances the contrary has been known to take place ;J and in one or two cases I have my- self been a witness to an extensive abscess. But the general rule is not disturbed by such rare exceptions. The inflammation there- fore is of a peculiar kind. There will often, indeed, be effusion, and the limb will swell considerably ; but the effused fluid is gradu- ally absorbed; and the swelling not unfrequently, though not al- ways, is accompanied with an alleviation of the pain. Sometimes the pains take the precedency of the fever; but in other cases the fever appears first, and the local affection does not discover itself till a few days afterwards. There is no joint, except perhaps the extreme and minute joint of the fingers and toes, but is susceptible of its attack, although it usually commences in, as al- ready observed, and even confines itself to, the larger. Among these, however, it frequently wanders most capriciously, passing ra- pidly from the shoulders to the elbows, wrists, loins, hips, knees, or ancles, without observing any order, or enabling us in any way to prognosticate its course; always enlarging the part on which it alights, and rendering it peculiarly tender to the touch. Sometimes it darts internally upon organs we should little expect, as the dia- phragm and the pleura ; and I have occasionally known the stomach as suddenly and severely affected as in gout. It is also said at times to pitch upon the heart and the intestinal canal, and to produce ex- cruciating torture in both these organs. The urine is often at first pale, but soon becomes high-coloured, and deposits a red sediment. It may be distinguished from gout by being little connected with dyspepsy, commencing less suddenly, evincing more regularly mark- ed exacerbations at night; but less clear remissions at any time : to which, as already noticed, we may add its attachment to the larger rather than the smaller joints. It runs on from a fortnight to three weeks: and the average of the pulse is rarely under a hun- dred. * Smyth, Med. Commun. h. 19. t Comment, de Morbis quibusdam. Art. 79.

The fever is generally accompanied with copious and clammy sweats; but the skin still feels tense and harsh ; nor does the -weat issue freely from the immediate seat of pam. It seems to be an in- effectual effort of the instinctive principle or remedial power ot nature to carry off the complaint: for it is by this evacuation alone that we can at length succeed in effecting a cure. But the perspi- ration will be always found unavailing so long as it continues clam- my, and the skin feels harsh, and there is a sense of chilliness creep- ing over the body or anv part of it during the perspirable stage. The exacerbation, which regularly returns in the evening, increas- es during the night, at which time the pains become most severe; and are then chiefly disposed to shift from one joint to another. Where the fever is violent, and especially where the frame is ro- bust ; our only effectual remedies are copious bleeding and the use of diaphoretics ; by the former, which will often demand repetition, we take off the inflammatory diathesis, and by the latter we follow up the indication which nature herself seems to point out, and en- deavour by still farther relaxing the extremities of the capillaries to render that effectual, which without such collateral assistance is, as already observed, for the most part exerted in vain, and an un- profitable expenditure of strength. The most useful diaphoretic we are acquainted with is Dover's powder; and its benefit will often be increased if employed in union with the acetated am- monia, and sometimes if combined with camphor. Aperients are useful to a certain extent, but they have not been found so ser- viceable as in various other inflammations. Small doses of calo- mel have occasionally, however, seemed to shorten the term of the disease, though they have not much influence in diminishing the pain. To obtain this Dr. Hamilton has combined calomel with opi- um ; and in his hands it appears to have been successful. Opium alone is rather injurious ; nor has any decided benefit resulted from other narcotics, as hyoscyamus, hemlock, and aconite. They are recommended by several writers, but I have seen them tried both in small and large quantities without effect. We have observed that there is no constitution invulnerable to the attack of rheumatism, although the young and the vigorous fall most frequently a prey to its torture. Hence not unfrequently we meet with it in persons of weak and irritable habits, who will not bear the lancet with that freedom which gives any chance of its being useful. Local bleeding is here to be preferred ; but it can- not be depended upon : since, though the pain may diminish, or even totally subside, it is, in many cases, only to make its appear- ance in some other quarter. Here, also, if in any case, we have reason to expect benefit from uniting stimulants with diaphoretics. as ammonia, camphor, and the resinous gums and balsams. In such habits and particularly if opium should disagree with the system, it may be worth while to try the rhododendron (r. Chrysan- thum Linn.) This plant is a native of the snowy summits of the Alps and mountains of Siberia; and in Russia, as we learn from Dr. Guthrie, is employed very generally both in gout and rheu- OE. XII.-SP. I.] SANGUINEOUS FUNCTION. 329 matism with a full assurance of success, a cure seldom failing to be effected after three or four doses :* in consequence of which it has formed an article in the Materia Medica of the Russian Phar- macopoeia for nearly a century. Dr. Home tried it upon a pretty ex- tensive scale in the Edinburgh Infirmary, and found that it acts both as a powerful diaphoretic and narcotic; and is at the same time one of the most effective sedatives in the vegetable kingdom. In most of the cases it retarded the pulse very considerably, and in one in- stance reduced it to thirty-eight strokes in a minute. It has also the advantage of occasionally proving aperient. But it sometimes pro- duces vertigo and nausea; and as a general medicine is not to be preferred to Dover's powder,t or even the antimonial powder with opium, where the latter can be borne without inconvenience. It is possibly also in habits of this irritable kind, if in any, that we are to look for that extraordinary and decisive benefit from a free use of the bark at an early period of the disease, which we are told has accompanied it, by authorities which we cannot dispute. Contemplated as a highly acute inflammatory affection, nothing could at first sight appear to be more inconsistent with all rational prac- tice than the use of such a medicine, and every one must feel pre- disposed to coincide with Dr. Cullen, when he tells us, in reference to aGute rheumatism, '; 1 hold the bark to be absolutely improper, and have found it to be manifestly hurtful, especially in its begin- ning, and in its truly inflammatory state."J Yet in direct opposition to such feelings and such assertion, confirmed by numberless testi- monies of equal weight, we find the bark freely prescribed from the onset of acute rheumatism, apparently with success, by Dr. Morton. who seems first to have employed and recommended it for this pur- pose, down to our own day, through a stream of the most celebrated physicians, as Sir Edward Hulse, Dr. Fothergill, Dr. George For- dyce, and Dr. Haygarth of Chester. Dr. Fordyce affirms distinctly that, at the lime of writing, he had for fifteen years relinquished bleeding in favour of the bark; and that during this period of time he had not above two or three patients out of several hundreds for which he had prescribed it; and had rarely met with any instance of a metastasis, a very common occurrence when he was in the ha- bit of employing copious bleeding.§ The success of Dr. Haygarth is not less striking and extraordina- ry : and the history of it is given with an air of candour that enti- tles it to full attention. Dr. Haygarth's residence was at Chester ; and his tract lays before us, the result of an extensive practice in rheumatic diseases, in that city and its neighbourhood, during a pe- riod of thirty-eight years. His cases amount to four hundred and seventy; and of these, one hundred and seventy, or something more * Med. Comment. Vol. v. p. 434. t Clinical Experiments, Histories of Dissections, 8vo.

[cl. iii.-or. n. than a third of the entire number, appear to have been cases of acute rheumatism, or rheumatism in conjunction with fever, the rest being of a chronic kind. In the acute cases, by far the greater number of patients had the joints alone principally affected, a few the muscles alone, and the' rest both the muscles and the joints. The average of the pulse in the above hundred and seventy cases, was a hundred strokes in a minute, and the blood always exhibited the inflammatory crust when drawn. Other remedies were tried, but the bark was by far the most successful. In four cases only out of a hundred and twenty one, it is allowed to have failed ; so that we cannot be much surprised at Dr. Haygarth's conclusion, that the bark does not cure an ague so certainly and so quickly as it does the acute rheumatism.* How are we to reconcile such conflicting results, and harmonize the authorities now adverted to ? I have also tried the bark in va- rious instances from an early period of the disease, and when the bowels were free from confinement, but 1 have rarely met with suc- cess : and have often, like Dr. Cullen, had reason to think it injuri- ous. Is it that in certain habits, as those of great weakness and irri- tability ; in certain districts, as in low and swampy grounds, charged with the fomites of intermittents ; or, in certain temperaments of the atmosphere, as in sudden successions of wet and sultry weather, the bark has a tendency even in acute rheumatism, as we know it has in spasmodic affections occurring in weakly constitutions*, to take off tension and rigidity as well as to take off relaxation ; and thus to in- duce a healthy tone by letting down the action of muscular fibres, when necessary, as well as raising it when necessary also ? This view of the subject may account for its beneficial effects in many of the above cases, but will not explain the general and indiscriminate success which seems to have attended it: and hence, there is.still a something behind, some unknown principle or contingency, which yet requires to be brought forward before we can reconcile these " factis contraria facta." The above remarks will apply to other varieties of acute rheu- matism as well as to the first, that which affects the joints general- ly, and is the most common form under which the disease shows it- self; yet the few following observations more immediately direct- ed to the other varieties may not be altogether unprofitable. Lumbago has sometimes been confounded with nephritis, or a calculus in the kidneys or ureters; but the proper nephritic affec- tions are distinguished by some irregularity in the secretion of urine, and, as we have already had occasion to observe, with a numbness shooting down the thigh, and a retraction of either testicle Rheumatism of the hip-joint was called among the Latins ischias from «r;e«es, the Greek term for hip; which was afterwards corrupt- ed into isciatica or sciatica, a word that has occasionally found its * Clinical History of Diseases, 1805.

I.] SANGUINEOUS FUNCTION. 331 way into the dramatic poetry of our own country, as in Shakspeare's Timon, The cold sciatica Cripple our senato s, that their limbs may halt As lamely as their manners. This variety, at its onset, has sometimes been mistaken for a phlegmonous inflammation of the psoas muscle. But in the latter there is, from the first, less tenderness to the touch, but much more enlargement, and the pain shoots higher into the loins. In sciatica, indeed, the whole limb, instead of continuing to swell, soon wastes away, and the emaciation extends to the nates of the affected side, so that the muscles have neither strength nor substance; while the thigh becomes elongated from the fibrous relaxation that takes place. When acute rheumatism attacks the pleura, or any of its duplica- tures or appendages, it exhibits many of the symptoms of pleurisy or peripneumony. But here, also, as in every other case of rheu- matism, we have much greater tenderness upon pressure than in phlogotic inflammation, while the pyrectic symptoms are considera- bly less, and often highly disproportionate to the pain that is endured, so that the degree of pain and of fever becomes no measure for each other. There is this peculiar character belonging to the three last varie- ties, that though they are less disposed to wander generally than the first, they are peculiarly apt to run into each other's proper field, and to affect the stomach, which, in consequence, becomes some- times enormously flatulent and expanded, with a sense of heat like that of a burning coal. If the back or loins be pressed hard to ob- tain ease, the pain is transferred to the side or stomach ; and if the pressure be followed up into the side, it returns with violence to the back or hips; or the breathing is impeded, and can only be car- ried on in an erect position.* Generally speaking however, in these three varieties, the dis- ease is less erratic than in the first, and particularly in lumbago and sciatica. And it is owing to this fact, that the loins and the hip, from having been more uniformly affected, are often so long, even after the complaint has subsided, before they recover any degree of tone, so that the patient is frequently a cripple for many months; and still sutfers from chronic rheumatism, which in these cases proves no uncommon sequel to acute. Local applications, which are rarely of service in the first or ar- ticular variety, as the pain is so apt to wander from every joint to every joint, may in all these be frequently employed with more advantage; and where general and copious bleeding may be con- traindicated, leeches or cupping have often afforded considerable * CartheuserDiss. de Lunibagine rheumatica. Fr. 1755. Scueid, Diss, de Lumbag. rheumat. Arg. 1704. 332 II/EMATieA. [CL. 11I.-0R. U. relief. The compound camphor liniment, as an elegant rubefacient, is perhaps more frequently employed than any other medicine of the same tribe ; but it dries too soon upon the skin, and heats and stimulates without exciting moisture ; and hence it is less useful than camphor dissolved in oil, or oil united with ammonia. In all these applications, however, the Iriction with a warm hand is of itself highly serviceable, and should be long persevered in and fre- quently repeated. And on this account it is that essential advantage has often been derived in cases of lumbago, or where the rheuma- tism has fixt itself between the shoulders, by a waistcoat of the coarsest brown paper, worn close to the skin, which exites a gentle moisture, both by its perpetual friction and the stimulus of the tar with which it is so largely impregnated. Blisters seem rarely to be of all the advantage we should expect; but the vesication from sinapisms succeeds better than that from cantharides, probably because it operates with a wider continuous sympathy, produces more general excitement, and hence proves a better diaphoretic. The burning of moxa is a favourite remedy on the continent, but has been little tried in our own country. It does not seem to afford so much promise of relief as sinapisms or epi- thems of scraped horseradish. The tatar emetic ointment has been also frequently made use of, and sometimes with success: it gives a parmanent irritation, but the exulcerations it produces frequently prove foul and troublesome. Dr. Perceval of Dubhn, in a manu- script note to the volume of Nosology, tells me that, in sciatica, he has known the pain removed by a sweating course of James's pow- der, after a considerable emaciation of the nates. Bark and gentle stimulants, as guaiacum, bardana, and seneka, may in every instance be used with advantage, with a liberal regi- men and chalybeate waters. SPECIES II. ARTHROSIA CHRONICA.

Concerning the proper position, and, in some sort, the nature of this disease, Dr. Cullen confesses himself at a great loss. In his Synopsis, he arrange- it as a sequel of acute rheumatism, and so ex- plains it in his definition : yet he gives it a distinct name, that of GE. XII.-SP. II.] SANGUINEOUS FUNCTION. 333 Arthrodynia, for the express purpose, as he tells us, of having a dis- tinct name at hand for any one who may choose to regard it as a separate genus ; and whoever is so deposed is at full liberty, he adds, as to any objection of his own. Yet in his First Lines he takes a different view ; and perhaps a more correct one than either of the above. Chronic rheumatism, instead of being a mere sequel of acute rheumatism, or a distinct genus, is here made a separate species of a common genus. " Of this disease," says Dr. Cullen, " there are two species; the one named the acute, and the other the*chronic rheumatism." And in his subsequent description of the latter, in- stead of the universal assertion in his earlier work, '• pro sequela rheumatismi acuti rheumatismum chronicum dictum semper habeo," he modifies it by the word commonly. " The chronic," says he, " is commonly a sequel of the acute rheumatism."* There can be no doubt, indeed, that it is so; but as, in many in- stances, itis a distinct disease, characterized by symptoms of its own, and demanding a very different treatment, there can be as little doubt that it ought to be arranged as a distinct species ; and in the present system it is thus arranged accordingly. Chronic rheumatism has as many, and nearly the same varieties as the acute. It becomes fixt in the loins, in the hip, in the knee, but sel- dom in the thorax. Its symptoms are in most respects like those of acute rheumatism, only that there is little or no fever : so that while the general heat is very considerable, and the pulse usually upr wards of a hundred strokes in a minute in the acute species, the skin in the chronic species seldom exceeds its natural temperature, and the pulse is rarely quicker than eightly strokes; the joints are less swollen, and of a pale instead of being of a reddish hue, cold and stiff, and roused with difficulty to a perspiration ; and always comforted by the application of warmth. The disease continues for an indefinite period, and sometimes only terminates with the life. The affected joint is occasionally de- bilitated to the utmost degree of atony, so as, when the acute pain is not present, to resemble very nearly a stroke of palsy. Cold, the common cause of the acute rheumatism, is also a com- mon cause of chronic, even where the acute species has not preced- ed : and violent strains and spasms may be enumerated as other causes. But it is probable that in these cases the constitution is peculiarly disposed to rheumatic action. Every symptom proves most distinctly that the present is a dis- ease of debility; and the mode of treatment must be founded upon this idea. It is hence that stimulants of almost all kinds are found serviceable. Warm active balsams and resins, as those of copaiva and guaiacum, essential oils of all kinds, from resinous substances, as turpentine and amber; from aromatic or pungent plants, as cam- phor and mustard, and especially cajeput, the greenest distilled oil * Aph. ccccl. 334 FLEMAT1CA- [CL. ITI.-OR. n. from the leaves of the melaleuca Leucodendron, are all employed in their turn ; sometimes alone, where they combine a sedative with a stimulant power, as camphor and cajeput, and sometimes in union with opium, which often proves a very valuable addition. Most of these are, also, powerful diuretics; and as acute rheuma- tism is besfand soonest removed by warm sudonfics, so chronic rheumatism seems to be chiefly relieved, and, indeed, radically cured, by diuretics of a like stimulus. Hence, horse-radish and garlic are often found serviceable ; and turpentine still more so; which in truth forms the basis of the greater number of the medi- cines just enumerated. How far the arum, or dulcamara, may be specifically entitled to this character I cannot determine from my own practice. They are both introduced into the table of diuretics by Dr. Cullen, and are highly commended by many physicians of great celebrity for their arthritic virtues. But it is possible that whatever virtues of this kind they possess are rather derived from their stimulating the excretories generally, and rousing the entire system, than from their acting specifically upon the kidneys. The colchicum autumnale, which has sometimes proved serviceable, has more decided pretensions to a diuretic character. Local stimulants are, here, of more service than in the preceding species. The cautery of moxa has been more generally used on the continent for chronic than for acute rheumatism, and is certain iy more entitled to a trial. In our own country, however, practition- ers have far more generally had recourse to cataplasms of ammonia, cummin, and mustard-seeds, occasionally intermixed with cuphor- bium or cantharides: or, in their stead, have made use of friction, and, which is far preferable, the vapour-bath, brine, warm-bathing: and have afterwards kept the joint well clothed with flannel; and sent through the organ small shocks electricity, or roused it by the stimulus of the voltaic trough. And, when every thing else has failed, the patient is usually advised to try what perhaps, it would be better that he should try at first, the mysterious agency of the Bathwaters. The subject ought not to be dropped without briefly adverting to the internal use of the oleum jecoris aselli, common train oil, or that obtained from the liver of the cod-fish, not long ago so extensively tried, 1 had almost said so fashionable a remedy, in consequence of the warm and confident recommendation of Dr. Percival. This offensive material is procured by the process of putrefac- tion, and appears to derive its stimulant power, at least, as much from rancidity as from any natural quality. Dr. Percival tried it upon a large scale in the Manchester Infirmary, and with so much success, that, nauseous as it is to the taste, rheumatic patients, from being eye-witnesses of its benefit, were in the habit of applying to him for a course of it. Dr. Bardsley has since spoken of it in terms of nearly equal commendation; and Dr. Parr asserts, that " he thinks he has seen chronic rheumatism yield to a steady constant use of this oil, which had resisted every other remedy." Dr. OE. XIL—SP. II.] SANGUINEOUS FUNCTION. 335 Bardsley's dose was from one to three table spoonfuls in the course of the day. Some years ago the author of this work tried the train oil very steadily and perseveringly in several severe cases of chro- nic rheumatism, but with very doubtful success in every instance ; and certainly without any advantage whatever in one or two, in which the oil was punctiliously persevered in for a month, in the proportion of two ounces a-day. In slight cases, it may sometimes prove salutary, but its virtues cannot fairly stand in competition with those of the terebinthinate oils. The arsenic solution 1 have never tried in this complaint. It is strongly recommended by Dr. Bardsley,* and, in his hands, it seems often to have succeeded. It may be commenced in doses of ten drops, and gradually increased to double this quantity, and should be united with a few drops of laudanum if it sit uneasy on the stomach by itself. SPECIES III.

PAIN, INFLAMMATION, AND FULNESS, CHIEFLY ABOUT THE SMALLER JOINTS : RETURNING AFTER INTERVALS; OFTEN PRECEDED BY, OR ALTERNATING WITH, UNUSUAL AFFECTIONS OF THE STOMACH, OR OTHER INTERNAL PARTS J UNSUPPURATIVE. The origin of the term gout, or goute in French, is little known, or rather is almost forgotten. Among the ancients most diseases accom- panied with tumefaction were ascribed to a flow of some morbid fluid or humour to the part affected, which was called a rheum or defluxion : and the rheum or defluxion was denominated cold, hot, acrid, saline, or viscid, according to the nature of the symptoms. The Arabian writers ascribed even this cause to various diseases of the eyes, which were hence called gutta serena and gutta obsura, "clear or cloudy drops or defluxions," according to the external appearance. Rheumatism and gout were alike attributed to the same origin : and as the terms rheuma and gutla were used in medi- cine synonymously, both importing defluxion, the old opinion is still verbally preserved, and has descended to us in the names of rheu- matism and gout, though the old pathology has been abandoned. "• \\ e have still," says Dr. Parr, " the treatise of Carpinati publish- ed at Padua in 1609, De Gutta seu Junctuarum dolore;" but the term may be traced to Valescus de Tarenta, who wrote his Com- * Medical Report*. 336 H&MAT1CA.

H. mentary early in the fifteenth century; and Schneider in his Liber Catarrhorum Specialissimus, published at Wittenberg in 1664, usu- ally denominated the sixth volume, and peculiarly scarce, describes the gout as a catarrh."* The resemblance between gout and rheumatism is so close that the one is often mistaken for the other; and both by Bergius were regarded as convertible : yet, while the former chiefly fixes on the small joints, the latter attacks the large ; and the first is often here- ditary, while the second is rarely or never so. We have also ob- served already that gout is far more connected with a dyspeptic state of the stomach than rheumatism; that its incursions are, for the most part, more sudden, its nocturnal exacerbations less strik- ing, but its remissions much clearer. Gout, moreover, is a tar more complicated complaint than rheu- matism : and hence there is no disease to which the human frame is subject that has led to such a variety of opinions, both in theory and practice, many of them directly contradictory to each other, as the gout; and I may add, ihere is no disease concerning the nature and treatment of which physicians are so little agreed : so that to this moment it constitutes perhaps the widest field for empyricism, and the hottest for warfare, of any that lie within the domain of medical science. Is the gout a local or a constitutional affection 1 is it a spasm or a poison ? is its course beneficial or mischievous ? should its inflam- mation be encouraged or counteracted ? is it to be concentrated or repelled ? is it to be treated with cordials or evacuants ? with cold or with heat? with a phlogistic or an antiphlogistic regimen? No sets of questions can be more repugnant to each other than these are ; and yet there is not one of them but we may obtain an answer to either in the negative or in the affirmative, by applying to diffe- rent practitioners for this purpose. Shutting the door to disputation and unfounded theory as far as We are able, let us, in as few words as possible, attend to the clear and established history of this disease, as we would to that of any other, and draw our pathology, and our mode of practice from the principles which it will be fairly found to inculcate. In the first place, it is admitted on all hands, or at least with ex- ceptions so few as scarcely to disturb the general consent, that gout, in whatever way it shows itself, is a disease of the system; or, in other words, is dependent upon a peculiar diathesis or state of the constitution. And, next, it is as commonly admitted that this diathe- sis is, in some instances, original, and in others hereditary or deriv- ed. There are many persons in whom this complaint makes its ap- pearance, who can trace no such affection in the blood of their an- cestors ; and as such persons are specially distinguished by a habit of indolence, luxury, and indulgence, and particularly in the plea- sures of the table, it is from this habit that the gouty diathesis is * Med. Diet. App. GE. XII.-SP. III.J SANGUINEOUS FUNCTION. 337 supposed to originate. There are others, who, though exhibiting a life of great regularity and abstemiousness, afford proofs of the same diathesis in occasional paroxysms to which it gives rise: and such persons are almost always capable of tracing it hereditarily. For the diathesis having once established itself, keeps its hold on the sytem, and is propagated from race to race whatever be the man- ner of life of the individual, or the general state of his constitution; though there can be no question that those descendants are most subject to its paroxysms who indulge in the excesses that laid its first foundation. A gouty diathesis thus produced, like a phlogotic diathesis, to which in many respects it makes a near approach, may remain quiescent and not discover itself for years, till it meets with some occasional cause of excitement, when it shows itself by a sudden and painful disturbance of some part of the system, but a distur- bance of a very different kind, as well as affecting very different or- gans, according to the temperament, constitution, manner of life, or some incidental circumstance of the individual where the general health is sound, fixing on one or more of the extremities in the form of a peculiar but very acute inflammation that runs through a regu- lar paroxysm and gradually subsides: and, where the health is in- firm, and the general form debilitated, exciting great derangement in some internal organ or set of organs, and particularly those of digestion; or shifting from one form to another, and thus proving itself under every form to be the same disease, and laying a foun- dation for the three following varieties :— x Regularis.

And hence in its origin, as well as vol. ii. 4 3 338 HjEMATICA. " [CL. III.-OR. II. in the symptoms it evinces under a regular paroxysm, gout makes a near approach to various other inflammations of which we have al- ready treated; and |s more disposed to show itself, where it has been transmitted hereditarilv n men of robust and large bodies, of large heads, of full and corpulent, and especially gluttonous habits, or whose «kin exhibits a coarser surface in consequence of being covered with a thicker rete mucosum. Castration is said to act as a general preventive; but on what facts I know not: though, ad- mitting the truth of the assertion, it is not difficult to explain the reason, from the entonic energy demanded for the first production of the disease. ;uch is a brief history of the origin, hereditary transmission, and effects vf the podagric diathesis; which must be distinguished from the paroxysms to which it gives rise, and which constitute the only manifest indications of its existence. The paroxysms of gout are excited by certain occasional causes, some of which are obvious and some doubtful, or altogether un- known; but, without the co-operation of these, the gouty diathesis may remain unnoticed or quiescent in the body for years, or per- haps through the whole term of a man's life. And hence it is that we often see an individual, whose ancestors have been notorious for this complaint, pass the whole of his days without betraying any marks of it, while it appears in one or more of his children, perhaps in their very boyhood. The occasional causes are very numerous; for where the diathe- sis exists strongly, almost any thing that is capable of producing a general disturbance m the system, or of throwing it off the balance of ordinary health, is sufficient to become a cause ; and this whether the incitement be of an entonic or an atonic character. And hence pa- roxysms in different individuals are often produced by intoxication, or excess of eating; violent emotions of the mind, particularly the depressing passions, as grief and terror; sudden exposure to cold when the skin is in a state of perspiration; wet applied to the feet; great labour of the body ; severe application of the mind, especial- ly when protracted so as to break in upon a due allowance of sleep; cold, flatulent fruits, and often acidulous liquors; a sudden change from a spare to a full, or from a full to a spare, diet; excessive eva- cuations of any kind; and, occasionally, a sudden cessation of such as are habitual, as the suppression of a periodic hemorrhoidal flux, the cessation of the catamenia, or even the closing of an issue that has long been in a state of discharge. It seems, moreover, indisputable that the more violent the attack of a paroxysm, and the longer its continuance, the more the dia- thesis is confirmed, and the oftener the attack is renewed. On which account it is of great importance to alleviate and abridge the paroxysms as much as possible, and especially when they are as yet new to the system. Whether particular climates or countries are more disposed to favour the existence of gout than others, separate from the occa- €ME. XII.-SP. III.] SANGUINEOUS FUNCTION. 339 sional causes just adverted to, mav be doubted. Such an opinion, however, has prevailed among the vulgar as well as among many of th- more learned in most ages. Thus, among the Greeks, it was a popular belief that Attica was the hot-bed of gout, as Achaia was ©fophthalmy; whence Lucretius, Atthide tentantur gressus, oculeique in Achsis finibus.* Gout clogs the feet in Attica, the sight Fails in Achaia. And thus, too, in more recent times, we are told that China,t and even some of the Germio provinces, are exempt from the attack of gout, while in our own country it exercises an almost irresi-t-bie sway. The last assertion is true enough, but we are not driven to the variable nature of our climate to account for the fact. Thus far we can proceed safely respecting the general pathology of this Proteus-disease. But the moment we enter upon the field of its proximate cause, we are bewildered in a hopeless labyrinth, without a thread to guide our entangle'! footsteps amidst the growing darkness. There has, indeed, been no want of attempts to explain the subject, but thus far they have been attempts alone—ingenious conjectures rather than enucleated facts. Thus some, among whom was the learned Boerhaave, resolved the proximate cause of gout into a morbid texture of the nerves and capillaries ; and others, into a peculiar acrimony of the fluids; respecting the nature of which, however, those who adopted this view were never able to agree; several of them, like Hoffman, affirming it to be a tartaric salt, several a bilious salt, several again an acid, and several again an alkali. This morbid material, in whatever it consists, was supposed to be separated from the system and thrown off J during the continuance of the paroxysm, which, consequently, it became the duty of the physician to encourage. And by some pathologists it was held that the morbid matter thus despumated has, in various instances, proved contagious, and this not to man only, but to other animals as well: thus M. Pietsch inform^ us that he has known dogs affected with the same disease by licking the ulcers that have followed upon a tit of gout accompanied with chalk-stones. Dr. Cullen has taken great pains in a series of nine consequutive arguments to prove the error or absurdity of most of these opinions : and then he proceeds to establish his own ; which consists in regard- ing the proximate cause of a gouty diathesis as dependent upon a certain vigorous and plethoric state of the system ; and the proxi- mate cause of a gouty paroxysm as produced by an occasional loss * De Rer. Nat. vi. 1117. t Le Conte, Nouvnlles Memoires sur l'etat present de la Chine. Paris 1696. X Sciiarler Vers. ii. p. 176, who denies it: and Degner De Dysenteria, who maintains it. 340 HjEMATICA. [CL.

It is obviously a mere extension of the Cullenian doctrine of fever to the disease before us, and is chargeable with the same incongruity : for here, as in fever, the stage of strength or increased energy is made to depend upon the stage of weakness; as the weakness or loss of tone is made dependent upon a peculiar vigour and plethoric state of the system. There is, indeed, no great difficulty in conceiving how loss of tone may follow upon excess of energy ; but by what means recovered energy is to be a result of loss of tone, is a problem of more laborious solution. 1 have dwelt the longer upon this subject because it involves a very essential point in the remedial process, and one which has rarely been sufficiently attended to: before we enter upon which, however, it may not be inexpedient to take a fuller glance at the symptoms by which the different varieties of the disease are distin- guished. One of the marks by which a regular paroxysm of gout is said to be distinguished from that of rheumatism, is the suddenness of its onset. This is true, as Sydenham has correctly observed, with regard to the general course of regular or entonic gout, in which the constitution is in other respects perfectly sound. But in other cases the fit is often preceded by certain prodromi which those who have suffered from it before very sufficiently understand, and uniformly take as a warning; such as a coldness or numbness of the lower limbs, alternating with a sense of pricking or formication along their entire length; frequent cramps of the muscles of the legs ; a crassament in the urine ;t slight shiverings over the surface ; languor and flatulency of the stomach ; and sometimes a pain over the eye-lids or in some other organ.J The paroxysm is said by Dr. Sydenham, who has drawn its picture to the life, to show itself most commonly in January or February; but I have known it occur so often towards the close of the summer, and in the autumn, and have attended so many patients who have never had it except in the latter seasons, that the rule does not seem to be in any way very well established. The first attack is usually in one of the feet, most commonly about the ball or first joint of the great toe ; it commences at night or during the night, and there is sometimes, though not always, a slight horror, succeeded by a hot stage. The local pain and swelling increase in violence, the joint assumes a fiery redness, and the whole body is in * Pract. of Piiys. Part i. B. n.

III.] SANGUINEOUS FUNCTION. 341 a state of great restlessness. The symptoms remit sometimes towards the next morning, yet occasionally not till the morning after; but they still return during the night, though in a more tolerable degree, for three or four days, or even a week; when the inflammation subsides as by resolution ; the foot almost instantly recovers its vigour, as though nothing had been the matter with it; and if the patient have been antecedently indisposed, he enjoys, as on recovering from an ague, an alacrity of body and mind beyond what he has experienced for a long time before; the constitutional indisposition disappearing with the paroxysm. At the commencement of the disease, the return of it may be annual, or not oftener than once in three or four years; but it is perpetually encroaching on the constitution, so that the intervals gradually become shorter, and the attacks more frequent and of longer continuance : whence, as Dr. Cullen has justly observed, " in an advanced state of the disease, the patient is hardly ever tolerably free from it, except perhaps for two or three months in the summer." Nothing can be more specific, more true to itself, or more distinct from every other kind of inflammation than that of the disease before us, when thus exhibited in a regular fit; the inflam- mation of erythema does not differ more from that of phlegmon than both these, and indeed every other from that of gout: it never suppurates, never ulcerates when simple and genuine, however violent may be the attack, and though to the eye of inexperience the skin may seem to be on the point of bursting; while, in the midst of the severest pain, there is a sense of numbness, weight, and want of energy; insomuch, that if the pain could for a moment be forgotten, the limb would feel paralytic; and though the muscles which move the limb be not affected, they raise it or drag it along like a dead load. If the inflammation run through its course where it first fixes, it subsides by a resolution that leaves no external discoloration or internal weakness or disability; and if it make a transfer from one extremity to another, it passes with inconceivable rapidity ; the limb now affected being loaded with all the vehemence of the inflammatory action ; and that lately the seat of pain being all of a sudden restored to perfect soundness. It is rarely, however, that any metastasis takes place on its first appearance in a healthy constitution ; nor indeed till after various organs or the entire habit has been weakened by repeated assaults. We have already observed that it is the nature of the disease to weaken the habit in this manner, till the system is completely broken down, as well in mind as in body, and becomes a prey to its tyrannic control. In this case the paroxysms, though much longer and more frequent, are less violent and painful than at first; but there is no joint exempt from its incursion, nor perhaps an inter- nal organ that does not suffer from induced weakness : so that, in the language of Sydenham, " the patient exists only to be wretched and miserable, and not at all to taste of the happiness of life." 342 HyEMATICA. [CL* IH.-OR. »• It is a remarkable fact, hitherto indeed little dwelt upon and alto- together unaccounted for, that as the system advances in years and debility, and every other secretion progressively fails, that of calcareous earth seems to increase. Hence the bones of aged persons are more fragile and apt to break upon slight concussions; and the arteries and various other parts become ossified or loaJed with nodules of lime-stone ; and where a powerful sympathy exists between the kidneys and the stomach, and either of these is in an infirm state, we have a larger deposit of the same material in the kidneys or the bladder. A similar increase of calcareous earth takes place in the weakness of chronic gout; every affected joint becomes loaded with its secretion, which collects and hardens into nodules in its cavities, or in the adjoining cellular membrane, or bursa? mucosae, and rentiers motion uneasy or destroys it altogether. The lime-stone, moreover, as .t hardens, acts as a foreign irritant to the distended integuments, and produces, what simple inflam- mation of the gout never does, ulcerations and an offensive discharge. For the same reason nephritic calculi are often a sequel of gout when it has assumed a chrome form ; and the children of gouty parents are said to be hereditarily disposed to both complaints, some of them exhibiting a podagric and others a nephritic affection. Thus far, we have followed up the progress of a regular attack of gout in a constitution otherwise healthy and vigorous. But the same diathesis exists in systems of delicate and infirm health, and where there is a want of sufficient energy to work up a fit of inflammation, and throw it off at its appropriate outlets. And in such case, as soon as it becomes roused into action by any of the Causes of excitement already enumerated, it constitutes the secono variety, assumes the guise of various other diseases, as dyspepsy, hysteria, hypochondrias, palpitations of the heart, vertigo, hemi- crania, with several modifications of palsy or apoplexy. The stomach and bowels, however, form the chief seat of affection; the appetite is fastidious or destroyed ; a spasmodic stricture or painful oppression is felt in the epigastric region, or the stomach is distended almost to bursting with flatulence ; nausea, eructations, vomiting, and all the symptoms of indigestion follow, and are alter- nated with severe colic or costiveness. In the mean while the disease shows itself at times, in one or more of the joints in slight and fugitive pains, as though making an ineffectual effort to kindle up a paroxysm of proper inflammation, but which there is not energy enough in the system to accomplish ; whence the articular pains cease almost as soon as they appear; and the visceral derangement is renewed ; sometimes slowly subsiding after a con- tinuance of several weeks; and sometimes wearing out the entire frame, and terminating in abdominal or cellular dropsy. It sometimes happens, however, that while the general constitu- tion ot a podagric patient is tolerably sound, one or more of the internal organs form an exception to the general rule, and are less healthy than the rest. And as upon an excitement of gouty inflam* 8-E. XII.-SP. III.] SANGUINEOUS FUNCTION. 343 mation in a.gouty habit, the inflammation seizes ordinarily upon the weakest part of the body, it makes its assault u,>on s.jch or»an rather than upon the hands or the feet; or, if it commence in ^he latter, is readily transferred to it; constituting the third of the va- rieties before us, and which has usually been called retrograde or misplaced gout. And if the general system should, at the same time, be below the ordinary tone of health when the paroxvsm is thus excited by the force of some occasional cause, the organ affect- ed may evince great languor and painful inertness, as in the second variety, rather than acute inflammation, as in the first. The sen- sation in the stomach, instead of being that of a fiery coal, is that of a cold lump of lead ; in the head it changes from maddening pain to oppressive horror, in which the patient suddenly starts from sleep almost as soon as he has began to doze, from the hideousness of the ideas that rush across the mind and form the distracting dream. The fit is sometimes transferred to the bladder; in which case there is acute pain at the neck of the organ, stranguary, and a dis- charge of thin acrid mucus from the urethra. The rectum has also been occasionally the seat of metastasis, and has evinced vari- ous species of affection, as simple vehement pain, spastic constric- tion, or hemorrhoidal tumours. When thrown upon the lungs it mimics the symptoms of a peripneumony. In applying the art of medicine to the cure or alleviation of gout, our attention must be directed to the state of the patient during the paroxysms, and during their intervals: and particularly to the state of his constitution or previous habits, which, according to their character may demand a different and even an opposite mode of management. Let us commence with the paroxysmal treatment : and, first of all, with that of the inflammatory attack, as it shows itself in a regular fit of the disease. It was formerly the belief, as we have already seen, that a gouty paroxysm was an effect of nature to throw off from the constitution, and thereby restore it to a state of perfect health, some peccant matter forming the proximate cause of the distemper; and it was hence, also, conceived, in addition, to adopt the language of Syden- ham, that the more vehement the fit, the sooner it will be over, and the longer and more perfect the intermission. And in thi6 view of the subject there can be no question that the wisest plan must have been that of leaving the paroxysm to run through its regular course without interruption. Yet, as this hypothesis has long fallen into discredit, we are not in the present day prevented, on such ground, from endeavouring to subdue the inflammation of a gouty paroxysm by the ordinary means resorted to in inflamma- tions of any other kind, as bleeding, purgatives, sudorifics, local as- tringents, and even refrigerants. But a very general objection has since been taken to this plan on another ground, and that is, the great danger of repelling the disease to some internal organ oi 344 HSMATICA. [CL. III.-OR. H. more importance, and thus of converting a regular paroxysm into a case of retrograde or atonic gout. And in consequence of this ap- prehension, the practice, even in the hands of many of our most celebrated physicians, has, for a long period, been in the highest degree vague and vacillating. Sydenham prohibited equally purg- ing and sweating of every kind, whether gentle or copious, and only allowed bleeding where the patient was young and vigorous, and on the first or second paroxysm : while of cold applications he takes no notice whatever. He admits, however, the use of lauda- num where the pain is very acute : trusting chiefly for the cure of the disease to an alterant regimen and apozems to be resorted to in the intervals. Dr. Cullen allows bleeding with the same restric- tion as Sydenham, though he recommends the application of leeches to the inflamed part, as at all times a safer practice than the use of the lancet. Of cathartics and sudorifics he takes no notice other- wise than as these may enter into the general course of an anti- phlogistic regimen; he is decidedly adverse to the use of cold; and thinks that warm-bathing and emollient poultices, blistering, burn- ing with moxa, camphorate and aromatic oils, induce the inflam- mation to shift from one part to another, and consequently tend to repel the inflammation from the extremities to some more impor* tant organ: while opium, though it affords relief in present parox- ysms, occasions them to return with greater violence ; and, there- fore, he observes, by way of conclusion, " The common practice of committing the person to patience and flannel alone, is establish- ed upon the best foundation."* Now, as we have already seen that the gout, after it has shown itself in paroxysms, is never idle; that one paroxysm, in the opin- ion of Sydenham, Cullen, and every other physician, hastens on another, renders its intervals shorter, and its duration longer; and progressively saps all the energies both of mind and body, and ren- ders life itself a burden; it is of serious importance to inquire whether this fear of a repulsion, however well founded in some in- stances, is not allowed too generally; whether it be not possible to draw a definite line between the form of the disease in which it ought to operate, and that in which it ought not? and whether in the latter case we may not derive all the benefit from a full use of a reducing process, which is obtained in other inflammations, ac- companied with a like degree of constitutional vigour ? From the history of this disease, as it has already passed before us, we may draw this general corollary: that the specific inflam- mation of gout, or whatever other morbid character it may evinco, when once excited by some occasional cause into action, has a pe- culiar tendency to fix and expand itself upon the weakest parts of the system, and where several parts are equally weak, to pass in sudden transitions from one part to another, though transitions are rare where the system is sound. * First Linos of the Practice of Physic, Aph. dlxix. '.;!■:. XII.-SP. HI.] SANGUINEOUS FUNCTION. 345 In healthy constitutions the weakest parts are the extremities; and hence, in such constitutions, these are the parts, as we have already seen, in which the gout uniformly opens its assault. Here it commences, and here it runs through its course, seldom migrat- ing, or, when it does migrate, only passing from one extremity to another; as from foot to foot) or from one of the feet to one of the hands; and limiting itself to these quarters, because they are the weakest parts of the system: though, as just observed, in a thoroughly sbund constitution such migrations are not common. In unhealthy habits, however, the extremities are not the weak- est parts of the system, but perhaps, the stomach, or the heart, or the head, or the lungs, or some other organ; while several of these organs may, moreover, be equally debilitated, according to the idiosyncrasy, or to accidental circumstances. And true to the general rule, we see the gouty principle, when roused into action in habits of this kind, fixing itself from the first on one of those im- portant viscera rather than on the extremities; or roaming from one to another, on its alternating its course from these organs to the extremities, or from the extremities to these organs. And as metastases are rare where the system is sound, they become fre- quent in proportion as it loses this character, and especially in pro- portion to its debility in particular parts. These are rules which we cannot too closely study and commit to memory, and they seem to point out to us the line of distinction between that form of the disease in which we ought to entertain a prudent fear of revulsion, and that in which we may safely act without any such fear whatever. They directly lead us to two states of constitution that require a very different, and in many in- stances a very opposite mode of treatment; and seem to settle the important question before us, under what circumstances it may be expedient to employ a palliative plan; and under what a cooling and reductive. Let us commence with the first of these two states, forming a regular but violent fit of gout as it shows itself in a sound constitu- tion, and inflicts its torture on the hand or the foot. Guiding our- selves by the laws just laid down, there seems no reason why, in* stead of " committing the person to patience and flannel alone," we should not pursue the evacuating and refrigerent means employ- ed in entonic inflammations of any other kind, and have cause to expect a like success: such as bleeding, so strongly recommended by Dr. Heberden, and allowed occasionally by Sydenham, and emptying the bowels, relaxing the skin generally, and cooling the fiery heat of the affected limb by cold water or any other frigorific application. With a transfer of morbific matter we have now no longer to contend. Yet, even where such a cause is admitted, as in most exanthems, the plan thus proposed is, in many instances, pursued without hesitation. Thus, in measles, cathartics and vene- section are not only in general use, but often indispensable; in the height of malignant scarlet-fever, we sponge or wash the entire VOL. II. 41 34b' ILLMATIGA. [CL. HI.-OR. If- surface of the body with cold water; and in small-pox, not onl; purge freely, but expose the patient to the coldest atmosphere of the winter-season. ..... c In weakly habits, or idiosyncrasies, or incidental debilities ot particular organs, we have admitted that a metastasis as we have already seen, is a frequent result, and peculiarly marks the charac- ter of gouty inflammation; and here, indeed, refrigerants, violent purgatives, and venesection ought to be most sedulously abstained from; and not unfrequently the best practice we can adopt is that of " committing the person to patience and flannel alone." But what I am anxious to establish is, that, agreeably to the laws which regulate the progress of gout, a metastasis in sound and vigorous constitutions is rarely to be expected, and perhaps never takes place except from one extremity to another. In order that some internal organ may become the seat of transferred gout, it is neces- sary that it should possess a weaker action than the part from which the inflammation is to be transferred: but the parts of weak- est action in a sound and vigorous constitution are the extremities themselves: and it is probably because the living energy is, in all the extremities, upon a balance, that in a sound frame a metastasis, even from one extremity to another, is a rare occurrence. Local infirmity seems to form the only ground for a metastasis; but where health prevails generally, and all the organs are equally sound, admitting the inflammatory action, instead of being reduced and resolved, to be repelled, there is no one organ to which it seems capable of being transferred rather than to another; and in such case it would be most reasonable to suppose that the morbid entony would be thrown back generally and divided amongst the whole, from which division of labour little mischief could happen. As far as I have seen, the inflammation of a regular fit of gout subsides gradually, though rapidly, under the treatment now propos- ed, without any repulsion whatever. Yet, in a few instances, it has seemed to be repelled in part, whilst it has chiefly passed off by re- solution. For during the use of a cold pediluvium or shortly after- wards, I have known patients speak of a peculiar kind of aura creep- ing over them and through them, and exciting an undefinable sense of glowing which has lasted for a few minutes, without any inconve- nience at the time, or even any change in the pulse ; and certainly without any ill effect afterwards. But, it may be replied, there is no resisting facts. The cases are innumerable in which great mischief has resulted from the deplet- ing and the refrigerant plan; and, as we cannot always tell that all the internal organs are or are not in a state of sound health, it is most prudent to abstain from a practice which may prove highly in- jurious in case of a mistake. The answer to this remark is, that here, as well as in every other disease, professional judgment is to be called into exercise, and the practitioner is to draw largely upon that skill and discrimination which it was the object of his education to bestow upon him : and «3E. XII.-SP. III.] SANGUINEOUS FUNCTION. 347 thus bestirring himself, he will rarely fall into an error. That mis- chief has resulted, and frequently, from the use of the plan before us, cannot be denied by any one ; but that great and essential good, and an easy and rapid cure have been also, in hundreds of instances effected, must be admitted as readily. No clear distinctive line, however, has hitherto, as far as I am acquainted with, been acted upon or even laid down: and hence it is rather to be ascribed to a want of discrimination upon this subject that the evils adverted to are chargeable than to any mischief in the plan itself. Yet it may be doubted whether the injury produced even by an injudicious use of evacuants and refrigerants amounts to a thousandth part of that entailed on the constitution by allowing the gout to make its inroads tacitly and unresisted; till by degrees it triumphs equally over all the powers, as well of the body as of the mind, and, in the forcible language of Sydenham, " The miserable wretch is at length so hap- py as to die." Of the benefit produced by the external use of cold water the au- thor can speak from a trial of several years upon his own person, and is only anxious that others should participate in what has prov- ed so decisive a comfort to himself. The author, in the enjoyment of undisturbed health, amidst great exercise of body and mind, which however acted as a relief to each other, was, for the first time, in his forty-seventh year, attacked with a regular fit of gout in one of his feet, some of his ancestors having been subject to the same complaint. Having long before drawn the distinctive line of treatment just adverted to, and carried it successfully into practice, he was on the point of trying it on him- self, and particularly the affusion of cold water; but his family were so alarmed at the proposal, that he consented for the term of three days, but no longer, to follow the Cullenian prescription, and to em- ploy nothing but flannel and as much patience as he could command, The foot was in consequence warmly wrapped up, and the sofa re- ceived him when he quitted the bed. The inflammation was exten- sive, and very painful, the pain, however, remitted occasionally in the day, yet returned towards night with a vehemence that en- tirely deprived him of sleep, and kept him in a profuse perspiration ; but a perspiration that afforded no relief. The limited time having expired, and the inflammation having gradually augmented instead of subsiding, early on the third morning he called for a large basin of cold water, stripped off the flannel, and boldly plunged the foot into it for four or five times in succession. The application was pecu- liarly refreshing; the fiery heat and pain, and all the inflammatory symptoms diminished instantly ; he repeated the cold bathing two hours afterwards, and continued to do so through the whole of the day; the complaint gradually diminishing upon every repetition. He slept soundly all night, the pain was trifling, and the inflamma- tion had almost subsided by the morning: he was able to hobble a little in the course of the day; and in four and twenty hours more the fit completely disappeared, and he was capable of resuming his 348 HEMATIC A. [CL- HI.-OR. II. accustomed exercise of walking. For five or six years afterwards he suffered annually from a like attack, but always had immediate recourse to cold immersion or affusion. No paroxysm continued longer than about three days, nor any one ever confined him totally to his house for a single day. Since this period, the use of a car- riage has prevented the excess of fatigue which he had hitherto of- ten undergone ; but from a love of walking he still frequent!;/ in- dulges in it; and for about the last three years he has had neither gout nor any other complaint to interrupt his usual career of good health. During the preceding paroxysm, the appetite being good, the bowels regular, and the pulse not much quickened, he made use of no collateral means, nor ever found the use of the cold water productive of the least inconvenience ; though he has occasionally been sensible of a gradual creeping through the sytem of the pecu- liar aura just adverted to, which may perhaps be called the aura podagrica, but which constituted no unpleasant sensation. The practice before us, however, is by no means of modern inven- tion, however it may have become a subject of warm controversy in the present day. An active evacuant plan, both by venesection and purging, has never ceased to be in use among many practitioners, and is particularly alluded to by Sydenham, though with a view of entering his protest against it, as injurious to a free discharge of the peccant matter, which, in his opinion, required to be carried off: while, with respect to the external use of cold water, not to men- tion that it seems to be alluded to by several of the Greek writers, and especially by Hippocrates,* it has descended in a stream of re- commendation from Zacutus Lusitanust m 1641 to Kolhaas,J and Keck§ in 1788 and 1789; Bartholin speaks of the use of snow as a common application in 1661,|| and Pechlin both of snow and cold sea-water towards the close of the same century .TT But this treatment, I am ready to admit, has often been employed rashly, and sometimes with great and even fatal mischief. It.ought never to be ventured upon, except, as already stated, where the con- stitution is decidedly sound and vigorous; for though 1 subscribe to much of Dr. Kinglake's therapeutic plan, I cannot agree with him that a gouty paroxysm is a merely local affection. The treatment before us should be limited to those who are in full vigour, and per- haps entony of health; and is especially to be avoided where the stomach is dyspeptic, the lungs asthmatic, the heart subject to pal- pitation, the head to nervous pains or drowsiness ; or where there is any known disability in any other important organ. *• Aphor.

Leeches may, in many instances, be applied where vene- section would be of doubtful expediency; a liniment of oil of al- monds impregnated with opium, rubbed on the tumefaction with a pro- tracted and very gentle friction, I have often found highly serviceable in mitigating the pain ; and epithems of tepid water, as recommend- ed by Dr. Scudamore, alone or mixed with a portion of ether or al- cohol, formed by cloths wetted with the fluid, and applied to the in- flamed part, renewable as they become dry, in many cases prove a grateful substitute for cold water; and are preferable to poultices, warm water, or even vapour-baths, which too generally relax and weaken the joint, and prevent it from recovering its elasticity, after the paroxysm is over, so soon as it otherwise would do. At the samp time, the body should be cooled with gentle aperients or injections; and while drenching sweats are avoided, which never fail to be injurious, the breathing moisture or diapnoe should be imi- tated, which often breaks forth naturally in an early part of the morning, and is sure to afford relief after a night of distraction. Nor should opium be omitted where the pain is very acute ; for, while it affords temporary ease, it diminishes the duration as well as the violence of the paroxysm. Dr. Cullen, in his Practice of Phy- sic, seems disposed to postpone the use of this medicine till the pa- roxysms have abated in their violence, for when given in the begin- ning of gouty paroxysms he asserts that it occasions the fits tq return with additional fury. Yet it should never be forgotten, that it is a law in the history of gout, and one to which we have already adverted, that the frequency and vehemence of the ensu- ing paroxysms are measured by the violence of those that have preceded. In the mean while, the regimen should be light and inirritant; and; the diet below the standard to which the patient has been accustom- ed ; though to guard against a metastasis to the stomach, we must be cautious that we do not reduce it too much. His beverage should be cool and unstimulant: Sydenham allows him sound table beer, and, if he have been accustomed to stronger malt liquors, such a drink may be conceded to him. His chamber should be well ven- tilated, and his dress light and easy. In the two ensuing varieties, constituting atonic and retrocedent gout, we have a podagric diathesis grafted upon an unsound frame ; the unsoundness being general or local: and, however fearless we may be of the disease fixing on any internal organ in the preceding variety, we have here a constant apprehension that it may do so, and in many cases see it commence in such organs. In atonic gout, our uniform attempt should be to produce a trans- fer from the part on which it has seized, and fix it in the extremi- 350 HEMATIC A. [( L. 1II.-OR. II. ties, in retrocedent gout, on the contrary, to render the vacillat- ing attack on the extremities more permanent, and prevent it from shifting to anv other quarter. To obtain the first intention, we have to strengthen and even sti- mulate the system generally by warm tonics and a generous diet, and above all things to take off the severe suffering, in whatever it may consist, from the affected organ; for the longer the fit conti- nues there, the weaker it will become, and the less capable of any instinctive remedial exertion. At the same time we may so- licit the paroxysm to the extremities by putting the feet into warm water, and thus unstringing the tone of their vessels; so as to bring the standard of their atony below that of the affected organ. In atonic gout, the sufferings, though widely different according to the seat of the disease, are almost insupportable. In the head the pain is maddening, or the disorder is accompanied with great horror, or mimics the stupor of an apoplexy: in the stomach there is a faintness like that of death, with the sense of a cold lump of lead lodged within it; or there is a gnawing or a burning agony, or a spasmodic stricture which cuts the body in two, and renders breath- ing almost impossible; often also accompanied with a rapid and sinking palpitation of the heart. It is of importance, before we proceed, to determine accurately that these anomalous symptoms are really those of gout; of which we have chiefly to judge from the general character of the patient's constitution, his hereditary predisposition, habits of life, and the ailments to which he has been previously subject. In most cases, during the paroxysm, and especially, where the stomach is affected, the warmest cordials are necessary, as brandy, the aromatic spirit of ammonia, the tincture of ginger or of capsicum ; or, what is still better, usquebaugh. And it is always advantageous, and especially where the bowels are confined, to add to it some warm aperient, as aloes or rhubarb. Most of our family gout-cordials are made upon this principle, and judiciously consist of some active aperient and the hottest aromatics dissolved in ardent spirits. And the patient who is subject to these attacks should never be without having some- thing of this kind at hand, since the paroxysm often makes its onset without any warning. Yet he should resolutely forbear having re- course to any such medicine except in the time of necessity ; for an habitual indulgence in any of them will still farther debilitate the affected organ, and indeed the entire system; and hence quick- en the returns of the paroxysm, and render the stimulant antidote less availing. Most of the preparations of ether contained in the current Phar- macopoeia of the London College, may be employed with benefit in the variety before us, and particularly in that icy coldness of the stomach, accompanied with a numbness of the limbs and a rapid palpitation of the heart, under which it occasionally exhibits itself Phosphorus itself has sometimes been ventured upon in this case. GE. X1I.-SP. Ill*] SANGUINEOUS FUNCTION. 351 in the proportion of two or three grains to a dose dissolved in dou- ble the proportion of ether; but I have never employed it, and cannot speak of its good effects. Musk seems in many instances to have been of decided advantage if given in sufficient doses, as well in gouty affections of the head as of the stomach. The case related by Mr. James Pringle is strikingly in its favour,* and seems to have induced Dr. Cullen to make trial of it in similar instances, who found it produce sudden relief by free doses repeated after short in- tervals'; and this where the lungs as well as the head and stomach were the seat of transferred disease.! External irritants may also be beneficially employed at the same time, and particularly those of rapid action, as the compound cam- phor liniment, sinapisms, and the burning of moxa, or coarse flax as recommended by Hippocrates: at the same time the extremities, as already advised, should be plunged into the warm bath. But our sheet-anchor is opium ; and it should be given freely, and in union with some preparation of antimony, so as to act towards the surface generally, and thus restore to the living power its in- terrupted equilibrium. Small doses of opium will here be of no avail; and we may generally repeat or increase the quantity to a large amount with perfect safety. " In a case of the gout in the stomach," says Dr. Cullen, " I have by degrees gone on to the dose of ten grains twice a-day; and when the disease was overcome, the dose of opium was gradually diminished, till in the course of two or three weeks it was none at all: and in all this no harm appeared to be done to the system. We frequently find, that when a strong ir- ritation is to be overcome, very iarge doses may be given without procuring sleep, or showing any of those deleterious effects that in other cases appear from much smaller quantities given. All this appears from the practice now well known in tetanus, mania, small- pox, gout, and syphilis.''^ In retrocedent gout the same plan is to be pursued where the at- tack has actually shifted from the feet or hands to some internal organ. But where it still lingers in the extremities, though with slight pain and inflammation and frequent cessations, as though it were on the point of removal, we should increase the morbid ac- tion by local irritants applied to the joint, as camphor, ammonia- blisters, sinapisms, or the cautery of moxa or coarse flax ; and at the same time prescribe a light, but generous diet, with rather more wine than the patient is in the usual habit of taking; carefully avoid- ing all violent cathartics, and keeping the bowels moderately open with rhubarb, aloes, or the compound colocynth pill. In gout, however, the intervals of the mscvse arc of as much importance to be attended to as its paroxyms : and here, also, the mode of management under the first form should differ essentially * Physical and Literary Essays, Vol. n.

[«*•• HI.-OR. tl> from that under the second: for though the occasional causes may in many cases be the same, they have in the former to operate upon a vigorous, perhaps upon an entonic scale of power, and in the latter upon a scale decidedly reduced and atonic. In every variety all known occasional causes must be equally avoided. Where the diet has been too rich it must be lowered, and where too spare and abstemious, made more liberal. Indolence and a sedentary life must give way to regular exercise, and over-exer- tion of body or mind to repose and quiet. In the young, robust, and corpulent, whether the disease result from too great indulgence at the table, or an habitual taint, it may be requisite to abstain from animal food, wines, and formented liquors altogether; but where the sufferer has passed considerably beyond the zenith of life, and the luxuries of the table have become habitual, his ordinary fare should be reduced or diminished rather than entirely commuted. And in every change it is better to proceed slowly than to rush rapidly from one extreme to another: since nothing has so great a tendency to prepare the internal organs for gouty paroxysms, as such sudden and violent transitions. The bowels should be kept in regular order, and the hour of rest be early. A clue and unswerving attention to these general rules of the hygiene will often be sufficient to keep those free from all distur- bance of the gout for many years, and perhaps for the whole of their subsequent life, who have only known it in the form of a few regular paroxysms. But where the system, and especially the digestive function, is weak, and the patient has had anticipations of a tonic or recedent gout, or has actually suffered from its assaults, it will be necessary to superadd a course of invigorating medicines. There are three classes of remedies that generally pass under this name, stimulants, bitters, and astringents. The first increase the action, the two last augment the tone. Stimulants can rarely be employed alone, except in cases of emergency, for a lax state of fibres will bear little increase of action without, at the same time, suffering an equal increase of debility. But they may often, and in the case of gout perhaps always, be combined with astringents and bitters with great and decisive benefit. Upon this subject, however, I have already treated so largely under limosis dyspepsia, or indi- gestion,* that it is only necessary to refer the reader to that part of the work for the present purpose. Most of the celebrated specifics for preventing a return of gout, have been formed of these classes of medicines in combination, and especially of bitters and aromatics : and it is singular that although the variety of them which nature offers to us is almost infinite, they have been employed with little change from the time of Galen and Car.lius Aurelianus in the second century to that of Sydenham in the seventeenth. The famous powder purchased by the second Duke of Portland, who distributed its receipt for general use from the \"ot. I. Class I. Orri. i. C'j:i. v. t>nee. 7. n. 100. »E. XII.-SP. III.] SANGUINEOUS FUNCTION. 353 service it appeared to have rendered him, is formed for the most part of the very same ingredients, modified either from the Gre k writers, or Dr. Sydenham's prescription; though it is a simplifica- tion of the latter, by omitting several of the articles that enter into its composition, one or two of which had better be retained. In this reduced form it consists of equal parts of the five following ma- terials, finely powdered and intimately commixt: birthwort, gen- tiim, germander, ground-pine, and the tops and leaves of the leaser centaury. The dose is a drachm taken fasting every morning for three months; after which it is to be reduced to three quarter- of a drachm for three months longer; then to half a drachm for the remainder of the year: and after this the same dose is to be con- tinued, every other r#orning only, through the next twelve months; by which time it is presumed that a core will be accomplished. The real effect of this and similar medicines is very doubtful, and the doubt arises from the gradual mischief which a gouty dia- thesis has a tendency to produce in the corporeal system ; and the benefit which the exact and abstemious regimen that is prescribed during the use of the Portland or any other course of bitter tonics, is calculated to afford of its own accord. In some instances such medicines seem to have produced little or no effect of any kind; in others the joint result of remedy and regimen seems to have been highly salutary ; while in others again, the patients, though freed from open and decided fits of the gout, appear to have sunk gradual- ly under complaints more distressing and fatal than the gout itself, as dyspepsy, lowness of spirits, and dropsies of almost every part, especially hydrothorax, ascites, and anasarca. Now it is possible that the regimen alone may have produced the good, where good has been experienced, and the gouty diathe- sis the evil, where the evil has followed ; or that the bitter tonics themselves may have done both, according as the individual to whom they have been administered has been in a proper or im- proper state of body for a trial of them: For, as most bitters are sedatives as well as tonics, and some of them direct narcotics, there can be no question that they have" a tendency to prevent local in- flammation in a vigorous and robust frame as w< • is in a relaxed and debilitated. But tonics and even sedatives are as little called for in the former condition of body as they are demanded in the latter; and may perhaps prove as mischievous in the end as a sedentary life combined with prodigal eating and drinking. There must in both cases be too great an excitement of the sensorium, and secre- tion of sensorial fluid, and consequently too great an exhaustion of organic power with a perpetual tendency to torpitude in every part of the system. !n both cases fuel is added to fire, and the constitu- tion, if not bursting into open inflammation, seems to be equally consumed by a secret and smothered flame. The gouty diathesis is no doubt fed and confirmed ; and as regular fits of gout are kept off probably by the sedative quality of the bitter tonics employpd, we vol. nr. 45 354 HyEMATICA. [«- HT-OR. II. have reason to expect indigestion, low spirits, dropsv, and all the effects of high living, although the latter is relinquished. I have thus endeavoured to account for the very different effect which tonics, and especially bitter ton;cs, appear to produce in dif- ferent cases of gout, and tojustifv the caution with which they were given by the Greek physicians, as well as by later pathologists of high repute. They are not to be used indiscriminately: for while the relaxed and debilitated, those who are subject to atonic and re- trocedent gout, may have recourse to them with great advantage, they will be sure to prove injurious to those of high entonic health, and who are distinguished by attacks of gout in regular but vehe- ment paroxysms. It is nevertheless easy to conceive that some bitters, even among those in common use, possess more of the sedative and narcotic principle than others; and where this is the case, though such may be fittest for employment in the first instance, they ought to be drop- ped for others of a different kind, as orange-peel, bark, columbo, and serpentaria, as soon as all local irritation has ceased. The strongest bitter we are acquainted with is the nux vomica, and the narcotic quality of this is known to every one. Opium possesses it in a still higher degree. It has of late been suspected to exist in wormwood, and been distinctly traced in the hop and some of the lettuce tribe. Dr. Cullen, however, has taken a different view of this subject. He suppeses all bitters to possess a deleterious quality of some kind or other; and that in all gouty persons, or at least he makes no dis- tinction, they have a power of warding off fits of this disease ; but that, from this deleterious property, when long persevered in, they weaken the stomach and other organs of digestion, to which at first they gave tone ; and thus ultimately induce the diseases we have just noticed, and which are too apt to follow upon a debility of these viscera. And in proof of this opinion, he tells us of the fate of nine or ten persons who had been liable for some years before to have u a fit of a regular or very painful inflammatory gout, once at least and frequently twice in the course of a year; but who, after they had taken the Portland powder for some time, were quite free from any fit of inflammatory gout;" and, having completed the course prescribed, " had never a regular fit nor any inflammation of the extremities for the rest of their life. In no instance, however," continues Dr. Cullen, " that I have known, was the health of these persons ioierably entire. Soon after finishing the course of their medicine they became valetudinary in different shapes, and par- ticularly were much affected with dyspeptic, and what are called nervous complaints, with lowness of spirits. In every one of them, before a year had passed, after finishing the course of the powders, some hydropic symptoms appeared, which, gradually increasing in the form of an ascites or hydrothorax, especially the latter joined with anasarca, in less than two or at most three years, proved fatal. These accidents, happening to persons of some rank, became very GE. X1I.-SP. III.] SANGUINEOUS FUNCTION. 355 generally known in this country, and have prevented all such ex- periments since."* No testimony could be more confirmatory of the hypothesis I have ventured to lay down respecting the different effects of a tonic plan in different constitutions than the present. For the cases are taken entirely from persons who, upon this hypothesis, would entail upon themselves the very evils which are here described. And as Dr. Cullen gives us no account of any mischief that has fol- lowed the use of bitter tonics in constitutions of an opposite charac- ter, or marked by general debility and atonic gout, the evils he has described seem, on his own evidence, to be limited to those whom we have already cautioned against the employment of such a course. No proper classification or line of distinction seems to have been drawn or adhered to ; which would probably have presented us with very different results if it had been; and have superseded the clash- ing and unsatisfactory explanation of atonic effects uniformly produ- ced by a continuance of tonic medicines. The subject, however, requires to be further examined into by a more accurate classification of gouty patients who may be put under the influence of medicines of this kind; and 1 throw out the hint for this purpose. Yet, that a persevering course in bitter tonics does not uniformly prove in any way injurious to those who engage in it, is I think demonstrable from the daily use of table-beer in al- most every family throughout the country, and its appearing to be one of the wholesomest beverages we can adopt. Dr. Darwin, indeed, ventures to ascribe part of the mischief produced by high- ly spirited malt liquors to some noxious quality in the hops they contain ; but the stronger and headier malt liquors are uniformly prepared with a much smaller proportion of hops than the weaker, and especially than those which go under the name of table beer. For the only point aimed at by the employment of hops is to pre- vent an acetous fermentation ; which is effectually guarded against by the larger proportion of spirit contained in ale and strong beer; but which every one knows would soon take place in table-beer if it were not powerfully impregnated with this grateful bitter. And hence the remark of Dr. Darwin seems to have no foundation what- ever, since the stronger bitter affords a beverage proverbially wholesome; while the weak bitter is that which proves injurious. There have also, in all ages, been offered to the public specifics for the sudden cure or removal of the paroxysm when present, as well as for preventing its return hereafter. Lucian, in his Trago- podagra, gives us with great humour, a list that occupies a page of such as were chiefly in vogue in his day ; and the catalogue is certainly not diminished in our own. Those that have acquired the highest reputation appear to have been composed of some species of hellebore, or of meadow-saffron; the first of which is among the remedies quoted by Lucian; though it is probable that the ft£x* * Mat. Med. Part. n. Ch. n. 356 HtfMATICA. [CL. IH.-OR. H- 'EAAEBOPOY of the Greeks was a different plant from either the wh.i* or black hellebore of modern dispensatories The favourite specifics of the present day are M Hussonj hau medicinale, and the vinum colchici, or wine of meadow ^flron, in- troduced in the current Pharmacopoeia of the London College, chiefly upon the authority and recommendation of Sir Ev^ard Home The exact components of the former are kept a secret; though, it. basis is well known to be either the one or the other of the above plants, most probably the meadow-saffron. The effects of the F,au medicinale and of the colchicum-wine do not essentially differ; tor after taking about sixty drops of either the pulse becomes slower, and at length sinks, in about twelve hours, from ten to twenty strokes in a minute below its natural number, at which time the in- flammation subsides. The action of both medicines is accompanied with great languor and a deadly nausea or sickness, which termi- nates in vomiting, or a discharge from the bowels, or both. It the dose be in a small degree in excess, the symptoms are syncope, cold sweat, extreme prostration of strength, violent vomiting and purg- ing, a wiry and almost imperceptible pulse, or a state of utter and very alarming insensibility. And in some constitutions these effei ts have followed from the use of even a common dose. So that these preparations seem to be rather stronger drugged than the celebrat- ed oxymel colchici of Stoerck. Sir Everard Home made several trials of the colchicum wine on a dog, both by the stomach and by infusing it into his jugular vein. From thirty drops he recovered in about seven hours; from sixty drops in eleven ; but a hundred and sixty drops, thrown into the jugular vein, killed him, after having suffered great agony, in five hours. On opening him, the stomach, smaller intestines, and colon were highly inflamed.* And it is hence obvious that this me- dicine, like many other emetics and cathartics, acts rather upon the stomach, through the medium of the circulation, than on the system through the medium of the stomach. It is possible that the colchi- cum may act by a specific power on the peculiar inflammation of a regular fit; yet, as other intestinal irritants have occasionally pro- duced a like effect, and particularly the gratiola officinalis (hedge- hyssop) and ranunculus Flarnmula, the disappearance of the parox- ysm may also be ascribed to a transfer of action to the stomach and intestines. Generally speaking, specifics operate by a secret and in- explicable power, as the bark in intermittents, the vaccine virus in shielding the constitution against small-pox, and mercury in syphi- lis ; for though a ptyalism gives proof that the system is impreg- nated with the last, there are few practitioners so attached to the Cuilenian doctrine in the present day as to contend that the vene- real virus is carried off by the salivation, since we are perpetually beholding it carried off under the influence of mercury without any Salivation whatever. * Phil. Trans. 1816. Art. xn. xm. GE. XII.-SP. HI.] SANGUINEOUS FUNCTION. 357 Admitting yet, that the colchicum has a specific power over a re- gular inflammatory paroxysm of gout, it is clear that it has no such power over the gouty diathesis, since the paroxysm has never been so removed as not to return again. And it hence becomes a serious question, whether the mischief produced in the constitution by the employment of such violent means be not greater than the tempo- rary good obtained by the suppression of the inflammation ? and 1 do not think that either the F.au medicinale or the colchicum-wine have been noticed with a sufficient degree of discrimination fairly to determine this point. From the rapidity and force of the operation, it is clear that they ought never to he tried except in the first variety cf gout, or where the system is firm and healthy, and the disorder shows itself in a regular fit. And as it is highly desirable, for reasons already stated, to restram the violence of the paroxjsm, shorten its duration, and carry it off as soon as possible, the use of the one or the other of these medicines may be judicious so long as the system is able to recover itself with speed from their influence, and provided the patient limits himself to the smallest dose that will answer the pur- pose. Yet these medicines, from too little attention to their real effects, and from a mistaken idea that they are a specific for gout under every form, have not been confined to the entonic variety, but have been very generally employed also in the second and third varieties as well; in which the system, and particularly the digestive organs, (re in a state of chronic debility, and the inflammatory fit, when it shows itself in the hands or feet, is incomplete and evanescent. In all such cases, such medicines cannot fail to do serious injury to the constitution; they must of necessity increase the ventricular weak- ness, and herehy render the system more open to all the miseries which gout is so perpetually entailing. And hence the reason of the very general complaint among those who have tried these remedies, that, although they remove the fit at the time, they shorten the in- tervals, and render their frames more obnoxious to relapses. The subject must not be quitted without a brief glance at Dr. Bal- four's proposed mode of treatment, which consists in the use of com- pression and percussion alternately applied to the inflamed gouty joint; as they are applied in like manner to parts labouring under acute rheumatism or any other kind cf inflammation. The opera- tor is directed to seize the aching toot forcibly, by grasping the ball of the toe in his right hand, and gradually to increase the pressure, and continue it till the impetus of the vessels has yielded to the greater impetus of the hand ; only occasionally letting go his grasp for the purpose of interposing a discipline of gentle percussion as it is called. This plan 1 have never tried, for I have never been able to summon fortitude enough to propose the addition of a remedial torture to that already endured from the disease ; nor do I think 1 have ever attended a patient who would have consented to the advice if I had 358 HvEMATICA. |>L. W.-OK. II. given it. The direct object is to overcome the inflammatory action by constringmg the vessels; but this effect is more readily obtain d, and in a far easier way, and with quite as little risk, by cold water. If in the course of the compression the inflammatory action do not soon yield, it should certamly be relinquished ; for a violent re- action will accompany the resistance, and the inflammation be great- ly augmented. I have seen one or two striking examples of this on applying the same method to inflammation* of other kinds. A young woman with a small ulcer in the leg of about three months stand- ing, which, apparently, had continued open merely from neglect, was received not long since as a patient into a public establishment of this metropolis, and a tight compressing bandage applied to the entire limb. A forcible re-action ensued, the local irritation extend- ed, the leg swelled in spite of the bandage, and the pain was acute. A few palliative means were interposed, but the compressive plan was still persevered in : the inflammation spread deeper and wider, gangrene soon followed, and the patient died within three weeks from the commencement of the trial. Linneus pursued a far more inviting specific for the cure of the gout, in his own person, which was that of eating strawberries. The story is pleasantly told by M. Hedin in the Amcenitates Aca- demical. And having in this agreeable manner driven away the paroxysm by which he was then assaulted, he persevered in the same mode of relief through five other fits which attacked him an- nually, every attack however being slighter than the preceding; till, by persisting in the same fruit, the disease, it is said, did nc£ show itself for nearly twenty years. We are told in some of the foreign journals of like cures being effected by eating sour cherries. And, as astringent tonics are often as useful as bitter tonics, it is possible that the gouty diathesis has, in some instances, been check- ed or subdued by acids of various kinds, though we should be often deceived if we placed any dependance upon them.

The ordinary occasional cause is a strain, or some other injury to the joint affected ; but this cause does not equally operate in all per- sons to the production of such a result; and it is hence obvious that there is, as in the case of gout and rheumatism, a predisposition or peculiar diathesis favouring the origin of hydarthrus, existing in some individuals to which others are strangers. And we find this predisposition showing itself also, as we have already seen, in the podagric diathesis, both in persons of a strong, robust, and entonic state of health, and in persons of relaxed and inelastic fibres, par- ticularly in those who inherit a scrophulous taint. And hence the disease exhibits itself under two distinct forms; seats itself in dif- ferent parts of the joint, and demands a very different mode of treat- ment. The varieties therefore are the following: a Entonicus. Entonic White-Swelling. C Atonicus. Atonic White-Swelling. The first variety is the rheumatic white-swelling of Mr. B. Bell, who has treated of the disease very fully and very judiciously in his work on ulcers.* l,t occurs, indeed, as he remarks, most fre- quently in young plethoric people in whom the rheumatic diathesis is predominant: or rather that firm elasticity of health and fibre, which, upon the application of accidental causes, gives rise to rheu- matism as well as to the present variety of hydarthrus: and on this account the epithet of entonic is preferred to that of rheumatic. These causes I have stated to be chiefly strains, and other exter- ternal injuries to the larger joints, as bruises and luxations: but, like rheumatism, it is also frequently excited by a current of cold damp air. The pain is diffused, the swelling considerable from the first, and the inflammation, on dissection, is found to originate and be chiefly seated in the synovial membrane and surrounding liga- ments ot the joints : though, according to Mr. Brodie, it sometimes commences in the circumambient cellular substance.! The intu- mescence feels tense and elastic, but there is little discoloration at any time. From the increased and morbid action of the vessels there is not much effusion of coagulable lymph, but a considerable surplus of synovial fluid, not less than four ounces of which was dis- charged in a case related by Dr Simson, by making an opening through the integuments and synovial membrane. I he occasional cause was in this instance of a singular kind ; for it consisted of a small supernumerary bone, somewhat above the size of a kidney-bean, which lay loose in the knee-joint and was covered with cartilage. * Treatise on Ulcers with a Dissertation on White-swellings, &c. 8vo. t Pathological and Surgical Observations on Diseases of the Joints, 8vo. 1818. 360 HJEMATICA. [cl. III.-OR. n. At first it seems to have been attached, for the patient does not ap- pear to have noticed it till about the commencement of the inflam- mation, when he frequently felt it, as a hard body of whose nature he was ignorant, immediately under the pate la, generally on the inside, but sometimes on the opposite, and could get no ease till by chafing the joint with his hand he made it disappear Upon a re- moval of the preternatural bone by an incision and an evacuation of the synovia, the patient appears to have been instantly relieved; for, contrary to the advice of Dr. Simson, he shortly afterwards mounted his horse and rode home through a distance of two miles and in a frosty night. But he had soon reason to repent of his im- prudence, for he caught cold, and suffered excruciating pain from inflammation, and did not recover the full use of his limb for nearly a twelvemonth. A caustic applied to the part and kept open seems to have been of essential service.* The inflammation, if not checked at its commencement, soon ex- tends into the cellular substance and even the integuments, but rarely in this variety affects the bone : but it has as little tendency to the adhesive as to the suppurative character, and hence the effused fluid runs in every direction, and, from losing its finer parts by absorption, becomes viscid and glairy, and occasionally ex- hibits a congeries of hydatids. If, however, the inflammation pro- ceed farther and the integuments be affected, pus is also secreted; the periosteum is ulcerated, and the bone itself rendered carious; so that on an examination, by dissection, the interior of the joint displays a confused union of different materials and substances blend- ed into a common mass. It is rarely that this variety is taken notice of so soon as it should be ; for when a strain occurs in the knee or elbow of a robust and high-spirited school-boy, he will generally rather suffer the pain it produces as long as he can, than run the risk of an abridgement to his liberty. When, however, the disease produced by such accident is taken in hand soon, it will usually yield in a few weeks to the ap- plication of leeches, succeeded by a repetition of blisters, which, if the joint be the knee or ancle, should be accompanied with a reclin- ed position ; for perfect quiet is of the utmost importance, and the joint should be kept as much as possible free from motion. If the swelling and inflammation should nevertheless proceed, the pain augment, a fluctuation be perceptible, and relaxing cataplasms have proved of no avail, the joint must be opened by a seton, which should be of sufficient depth and length to form an exit for the puru- lent fluid now contained in all the little abscesses that constitute the disease, and which are generally ?eparate from each other. As the bone does not readily become affected nor even the periosteum, the joint may in this manner often be preserved and restored to use. A very considerable degree of stiffness, indeed, * Edinb. Med. Essays, Vol. iv. Art. xx. GE. XI1.-SP. IV.] SANGUINEOUS FUNCTION. 361 will commonly remain long afterwards; but which in most cases will gradually yield to friction with the hand alone, or, which is better, illined with warm oil (and the animal oils are for this pur- pose preferable to the vegetable,) continued for an hour at a time and repeated at least twice a-day. The rigidity, indeed, is owing, in almost every instance, to the motionless state in which the flex- or-tendons have been kept for many weeks, and not to any inflam- mation that has extended itself to them, which, in nineteen cases out of twenty, according to Mr. bell's calculation, never takes place : and still less are we to fear such a result from an union of the ends of the adjoining bones, in consequence of the abrasion of their sur- rounding cartilages ; or from an inspissation of the synovial fluid by which they are surrounded. For it has already been observed that such abrasion rarely or never happens but in a very late stage of the disease ; while it is very uncertain that such a state of the syno- via as is here alluded to takes place at any time. And hence no such apprehensions should slacken our endeavours to remove the stiffness of the joint by a long course of friction and emollient appli- cations. When the use of the seton has produced no benefit, and the bone has manifestly become carious, our last resource is amputa- tion. The atonic variety commences, and consequently is chiefly seat- ed, in the bone itself of the affected joint, originating, as Mr. Brodie observes, in its cancelli.* The pain, therefore, is here more cir- cumscribed, and appears to shoot almost from a point, and the swel- ling is inconsiderable. The pain, however, though more limited, is very acute, and increased by the least attempt at motion; so that, in this case also, the muscles being always kept quiet and in a bent position, a stiffness of the joint is readily superinduced. The inflammation proceeds more slowly than in the entonic form, but it produces at length the same effect; the tumour ac- quires the same elastic feel; varicose veins appear on the surface, and collections of matter take place in different parts of it. The mmute and separate abscesses burst one after another, and discharge an ichorous or cheesy and purulent fluid, and small exfoliations of the subjacent bone are occasionally thrown out at the openings. This variety constitutes the scrophulous white-swelling of Mr. Bell; and, if not always confined to scrophulous subjects, is most common to those who give proofs of this diathesis, or of an approach to it. " I conceive all such collections of matter," says Mr. Hunter^ "to be of a scrophulous nature: they are most common in the young sub- ject, and seldom found in the full grown or old. The suppuration is not proper pus, nor the swelling proper inflammation."! The occasional causes are sometimes those of the preceding va- riety; but the disease more generally commences without our being * Patholog. and Sug. Observ. t On Blood, &c. p. 391. VOL. 0. 46 362 H/EMATICA. [CL. III.-OR. U, able to trace any occasional cause whatever : and is far more dispo- sed than the preceding to terminate in a fatal hectic. The practice is most disheartening and the prognostic most mel- ancholy No course of medicine promises much success; while even a removal of the limb may only lead the way to an appearance of the disease in some other joint. The pain may be soothed with opium; and local stimulants have been found useful in a early stage of the disease, or where the diathesis is not decidedly scrophulous. Of the last class of medicines almost every preparation has been tried in its turn according to the inclination of different practitioners: as solutions of muriated ammonia, sometimes commixed with acetic acid; essential oil of turpentine; camphor; acetated ammonia ; tincture of cantharides ; mezereon in various forms ; mercurial or other irritant emplasters; the actual cautery both by moxa and heat- ed irons; fumigations and the vapour-bath impregnated with essen- tial oils ; setons, and electricity.* While internally have been adminis- tered the compound decoction of sarsaparilla, hemlock, Pulsatilla nigra, and various preparations of almost all the metals.t Where these fail, and they fail too often, our only resource against the cer- tain destruction of hectic fever is amputation, however doubtful its issue. Dr. Akenside thought he derived advantage from large blis- ters, freely kept open, in conjunction with the internal use of calo- mel : but he candidly admits that nothing can be expected even from this treatment, or indeed any other treatment, where the disease has made much progress, or if " there is any sensible collection of a fluid within the joint." In two or three of the cases he has descri- bed, the tumour, when in an incipient state, seems to have been quite as favourably acted upon by the attack of some unforeseen ex- anthem, as small-pox or miliary eruption, as by any topical plan whatever.J * Heister, Wahrnehmungen B.

Krujjtfte jFebcrs. cutaneous eruptions essentially accompanied with fever. The term Exanthemata among the Greeks, from t%xv6ta, " efflores- co," " per summa erumpo," " to effloresce, or break forth on the surface" imported cutaneous efflorescences or eruptions generally. It has since been limited to express cutaneous eruptions accompanied with fever, a boundary assigned to it by Sauvages, Linneus, Vogel, Sagar, Macbride, Cullen, and various others, and this, in effect, is its general meaning in the present day. Dr. Cullen, however, in his note on Exanthemata, thinks it worth considering whether the word should not be restrained to eruptions (he does not say febrile eruptions) produced alone by specific contagion: " eruptiones a contagione specifica ortae;" while Dr. Willan has still more lately narrowed it so as to include those, eruptions only which fall within the meaning of the English term rash, whether febrile or not febrile. The two last senses of exanthemata, or exanthematica, are new and singular. Dr. Cullen, however, has not followed up his own suggestion into his own classification; while Dr. Willan has not al- ways continued strictly true to his own views and definition, as I have observed in the running comment introductory to the present order in the volume of Nosology to which the reader may turn, for a fuller examination of this subject, at his leisure. The term, therefore, in the present work, is employed in its common and current sense, so as to include all cutaneous eruptions in which fever exists as an essential symptom; whether accompa- nied with or destitute of contagion; which last is a doubtful ant%, " flatus, bulla,'1 and hence inflation, bladder, bubble. The idea of flatulency, however, is seldom connected with this disease in modern medi- cine, though very generally in ancient. The term, in the sense in which it is now commonly understood, was, perhaps, first employed by Sauvages; and has since passed into common use. It is still doubted by many whether pemphigus is entitled to be considered as a distinct and idiopathic disease; and whether all its varieties and modifications may not resolve themselves into certain pecu- liarities of erysipelas or pompholyx, the latter of which con- sists of similar vesicles, or bullae, without fever;-or into mere symptoms of typhus or plague. Gulbrand appears to have been of the former opinion; and hence he has denominated the disease erysipelas vesiculare :* Dr. Cullen seems to have been of the latter at the time of drawing up his definition, and still later, at that of drawing up his First Lines, in consequence of which he dismisses it in a single paragraph as an affection concerning which he can say nothing. But the fourth edition of his Synopsis contains a subjoined note, which intimates that his opinion was altered in consequence of his having seen a patient shown him by Dr. Home, and who was la- bouring under this disease, as an idiopathic affection, at the time. And when to this we add the authority, not merely of the earlier writers, Bontius, Seliger, and Langhans, but of Withers, Clarkson, Christie, Ring, Braune, and Dr. Stewart of Aberdeen, it would be unpardonable not to allow it a distinct place in a general system of nosology. Upon a careful review it appears to offer the three following va- rieties, which run parallel with those of Dr. Willan, though not exactly taken from him :— x Vulgaris. Vesicles appearing on the second Common vesicular fever. or third day, occasionally not till the fifth or sixth; in successive crops; often extending over the * Act. Soc. Med. Hafn. Tom. i. ViE.

Preceded by tumefaction of the neck and throat; vesicles chiefly seat- ed on the fauces and conglobate glands ; occasionally producing abscesses; highly contagious. Vesicles irregularly oblong, with livid edges and commonly flatten- ed tops; appearing successively on different parts of the surface in infants a few days after birth; on breaking, purplish. The first variety, or common pemphigus, is the pemphigus ma- jor of Sauvages, a very marked case of which was given in a com- munication of Dr. David Stewart to Dr. Duncan of Edinburgh.* It appeared on a young private of the seventy-third regiment, who had for a fortnight or three weeks antecedently been unwell from a sudden retrocession of measles produced by an exposure to cold, and afterwards to a damp unventilated apartment. He was recem ed into the hospital at Aberdeen April 15, at which time he com- plained of head-ache, sickness, oppression about the precordia, thirst, sore throat, difficulty of swallowing; his tongue was foul, his skin hot, pulse from 110 to 120, rather depressed. The whole surface was interspersed with vesicles of the size, of an ordinary walnut; especially the breast and arms. In the interstices the appearance of the skin was natural; and the distance from one vesicle to an- other was from half an inch to a hand's breadth or more. The disease did not appear to be contagious, as the patient was a solitary instance of it, both where he resided before and after his reception into the hospital. His chief medical treatment consisted in bark and port-wine with acidulated drinks : many of the vesicles broke, and discharged a bloody and most offensive ichor; the cutis, upon a rupture of the vesicles, was for the most part sound, of a deep red hue, and in some places livid. A new cuticle was gradually pro- duced : and on April 27, being twelve days from his reception into the hospital, he was dismissed perfectly cured. In this case the bullae do not seem to have reached below the throat in an internal direction ; nor lower than this region in the severer case described ]oy Seliger. In the first instance, the vesi- cles appeared abruptly, and had bursted and were healed in seven or eight days. In Seliger's case they issued more gradually, and in successive crops, ran through a longer period, and were not healed till the twenty-first day.t In a case apparently of the same kind, * Edinb.

Ill, published by Dr. Dickson in the Transactions of the Royal Irish Academy, there is evident proof of their having extended from the fauces throughout a considerable part of the alimentary canal: here also the vesicles appeared in successive crops, especially on the ninth, tenth, and thirteenth day, each crop continuing four or five days before it bursted; the fever was accompanied with delirium, but abated on the fifteenth day on the appearance of the catamenia, and the bulla; healed in succession without any trouble.* None of these appear to have been contagious. 1 cannot speak of pemphigus from personal knowledge; but in all the above instances the fever was of a low or typhous type ; and the disease seems to have approached the nature of erysipelas, as it was treated successfully by the means usually employed for the latter. For what little knowledge we possess of the second or glandular variety, the contagious pemphigus of Dr. Willan, we are chiefly indebted to Dr. Langhans, a Swiss physician, who observed it in the spring and through the summer of 1752 in the low-lands of his own country.! It commenced with a sense of tension in the fauces, and a slight pain spreading behind the ears to the anterior part of the thorax, accompanied with the symptoms that mark the first stage of fever, but not succeeded by a hot fit. A greenish bilious matter was sometimes thrown up from the stomach, and the pulse was feeble. The neck swelled externally and internally about the fau- ces, bullae were observed of the size of a filbert, producing little pain, and containing a yellow ichor of an offensive smell. Soon afterwards similar vesicles were found scattered sparingly over the body and limbs, which, if not broken or opened, collapsed in the second, third, or fourth day, and dwindled into whitish crusts. During this period the tumour of the neck often suppurated, or other suppurating tumours formed in some of the conglobate or conglomerate glands, as the parotid, axillary or inguinal; and the virus of the disease being thus discharged by different outlets on the surface of the body, the patient recovered. But if before this translation to the surface, there were a sense of weight and anxiety about the tho'rax, a large abscess was formed internally, and on its bursting, the patient died from suffocation. Or if the matter, lodged in the external vesicles, were by accident repelled before any glandular suppuration took place, he died almost as sud- denly. M. Langhans compares this disease to syphilis, but apparently with little reason ; and Dr. Cullen and Dr. Frank with not much more to rosalia paristhmitica. The cause, like that of the sweating- sickness, is altogether unknown, and like this disease also, after having ravaged with great fatality for a certain but a shorter pe- * Vol. I. 1787. t Act.

Sauvages, indeed, quotes a description of pemphigus from Thiery, which, by some writers, has been supposed to be the same ; but the account is so brief, and at the same time so loose and indistinct, that it is impos- sible either to arrange or reason about it. The glandular pemphigus of Switzerland, according to M. Lang- hans, was both contagious and epidemic ; so contagious, indeed, as to spread through numerous families with great rapidity, and so malignant that all persons affected by it died. This last assertion, however, compared with what follows, appears to be a little over- charged ; for the author proceeds, as already observed, to point out under what circumstances patients recovered from it; and lays down a remedial process, which, " though at first," says he, " I employed it with anxiety and hesitation, I can now with pleasure recommend to all persons labouring under the complaint with the most sanguine hope that it will effect a speedy cure." This successful practice, as in the sweating sickness, consisted in exciting a strong determination to the surface by active sudori- fics ; and at the same time supporting the strength with camphor and other cardiacs. He commenced his process, however, by ve- nesection, which was sometimes repeated, and, where there was danger of an abscess in the lungs, unquestionably with great judg- ment. The infantile pemphigus appears, as already noticed, most com- monly a few days after birth; but in one case adverted to by Dr. Willan, as late as ten months after this period. The vesicles show themselves on the neck, upper part of the breast, abdomen, groin, scrotum, and inner parts of the thighs. They arise successively, break, and expose a surface that heals with difficulty; and more generally enlarges its boundary, and wears out the little patient with pain, restlessness, and want of sleep. Warm cordials, as cam- phor and the aromatic confection, with a little port-wine-negus, form the best means of supporting the strength, and giving success in the struggle : and laudanum must be had recourse to where the want of sleep requires it. 406 1LEMAT1CA.

In describing the genus erythema, I endeavoured to point out a distinctive line between that inflammation and erysipelas, which are so often intermixed and confounded even by good writers; and observed that the first bears the same analogy to phlegmon, as the last to small-pox. Phlegmon is local inflammation tending to suppuration ; erythema, local inflammation lending to vesication: small-pox is an idiopathic fever producing a phlegmonous efflores- cence ; erysipelas an idiopathic fever producing erythematic efflo- rescence. Small-pox is always contagious; erysipelas occasionally so: phlegmon and erythema have no such tendency. The varieties of this species are very differently given by diffe- rent writers; by many of whom they are multiplied most unneces- sarily. Dr. Cullen makes even the herpes zoster, or shingles, a variety; but this is strangely to confuse simple cutaneous diseases with idiopathic fevers. For that erysipelas, when genuine, is an idiopathic fever dependent upon or productive of a specific virus is clear, because it has often, though not generally, been found con- tagious, and is capable of propagation by inoculation. " When the acrimonious lymph," observes Dr. Willan, " contained in the phlyc- taenae or vesications of a genuine erysipelas, is inoculated or casually applied to any slight wound in a person otherwise healthy, it pro- duces febrile symptoms, with a red and painful but diffuse swelling, analogous to that of the disease from which the virus was deriv- ed."* And he has added a case, in which the mother of a young girl severely affected with this disease appears to have received it in consequence of having nursed her. Dr. Wells has strengthened the doctrine of its contagious proper- ty by a variety of facts and cases that can scarcely, I should think, be read by any one without conviction.! One of his example* ex- tends to four individuals, who received the disease in succession af- ter direct contact or near approximation with each other; and ano- ther gives us a like line of not less than six in descent, all of whom, * On Cutaneous Diseases, p. 514. + Transact, of Soc. for the Improvement of Med. and Cbir.

VI.] SANGUINEOUS FUNCTION. 407 indeed, he did not attend personally, but the history of whom, as communicated to him by one of the affected, was confirmed by Dr. Pitcairn, who had been consulted by two of the rest, and was privy to the general fact. Dr. Pitcairn also communicated to Dr. Wells the fol- lowing highly important statement in addition : " A lady immediately after delivery was attacked with a fever which was accompanied with an affection of her skin somewhat like erysipelas ; her child, about three days after its birth, was seized with that species of erysipelas the French call la gelure, whiph first appeared about the pudenda, and afterwards extended itself to other parts of the body, among the rest to the face. Both the lady and her child died after a few days illness ; and about eight days after the death of the child, the lady's mother and servant maid, both of whom had attended it during its illness, were attacked with erysipelas of the face, from which both of them recovered." The opinion of Dr. Baillie, as communicated to Dr. Wells on another occasion, is to the same effect; to which Dr.Bail- lie seems to have been more especially led, by having observed in " a part of the years 1795 and 1796, that the erysipelas of the face was much more frequent in St. George's Hospital than he had ever before known it to be ; that many persons were attacked after they came into the hospital, and that the number in a particular ward was much greater than in any other." This last remark seems to give some countenance to the further opinion, that erysipelas becomes occasionally an epidemy, or ope- rates through the medium of the atmosphere, ;is weJl as by direct contact: though whether the atmosphere, in this case, be impreg- nated with the specific miasm of the disease, or merely predisposes the body to a more ready generation of it, has no more been deter- mined than in the case of various other exanthems that evince a like power. Dr. Parr asserts broadly, " we have four times seen it epidemic; and more than once we have had reason to suspect that it was communicated by infection."* At first sight it might seem easy from these accounts to subdivide erysipelas into the two varieties of contagious and uncontagious; but as it is most probable that the power of communication depends alone upon the peculiar diathesis of the person who receives it, as being endowed with a susceptibility of the disease not possessed by others, we can make nothing of this discrepancy : and shall hence examine it under the following varieties founded upon other cir- cumstances : x Locale.

The local erysipelas generally exhibits itself on one side of the face, or on some one of the limbs. In the former case the disease begins with coldness and shiverings, which alternate with irregular flushes of heat, and other symptoms of pyrexy. Dull aching pains are felt in the head, neck, and back. The swelling usually appears in the course of the second night or the third day ; though I have sometimes known it take place within a few hours after the at- tack ; the redness disappearing when pressed upon by the finger, but returning as soon as the pressure is removed. The eruption fixes itself on one side of the nose, or the cheek, temple, or fore- head : is of a dark red colour, smooth and soft, and attended with a sensation of heat and tingling. The redness and swelling extend gradually over the affected side of the face; and spread, in some cases to the scalp, and to the side of the neck or the upper part of the breast. Hence the face appears much disfigured; the mouth is drawn to one side; the eye-lids are turgid, and close up the eye, the fever increases, and is often attended with delirium. On the fourth and fifth day vesications arise on different parts of the dis- eased surface, especially about .the centre ; but with an increase rather than a diminution of the fever. The vesicles or bullae are of different sizes, and have an irregular base. The fluid contained in them is at first clear and watery: it afterwards becomes straw- coloured or opake, occasionally slightly livid, without losing its transparency. The cuticle gives way in a few places, and the fluid oozes through the cracks. About the eighth or ninth day, and some- times sooner, the redness changes to a brown or yellowish hue, the bullae subside, and the cuticle dries and desquamates or scales off. Occasionally both sides of the face are affected at the same time; though generally the morbid half is separated from the sound by an exact line drawn across the forehead, down the middle of the nose to the chin. The fever subsides about the eight or ninth day, hut Sometimes after its cessation it returns suddenly with as much vio- lence as at first, and continues two or three days longer. A sanious fluid approaching the nature of pus, and which by De Preval* and other writers seems to have been mistaken for pus itself, is some- times found in parts of the vesication: and from this circumstance Dr. Cullen has distinguished one variety of the disease by the name of erysipelas phlegmonodes; and has been copied by Dr. Willan. But a genuine phlegmon is never met with in erysipelas. " A cir- cumscribed cavity," says Mr. Pearson, " containing laudable pus is never seen in the legitimate erysipelas. Where a purulent effusion happens in any considerable degree, it affords, when the part is ex- amined, a sensation similar to that excited by a quagmire or morass. '■ Journ. de Mod. Tom. i.i. p. 315.—Eph. Nat. Cur. Dec. n. Ann. iv. p. 52. GE. H.-SP. VI.] SANGUINEOUS FUNCTION. ' 409 In that sort of suppuration, which sometimes supervenes to erysipe- las, the cellular membrane suffers great injury, and not uncommonly the part is in a gangrenous condition."* When the head is the seat of disease, it occasionally swells to an enormous magnitude, and, acccording to De Roma, the malady has proved fatal.t The disturbance of the constitution is less violent when the erythema appears in the extremities. The limbs most affected are the legs, in which probably from their depending situa- tion, the vesications fill rapidly and break within twenty-four hours from their first appearnce. Salmuth relates a case in which the in- tumescence extended over the entire frame :\ but this is extremely rare, excepting under the second or migratory form, in which it trails over different parts in succession, till the whole body has been affected. In the erratic variety, the complaint usually, and particularly in adults, begins its attack in the face, and spreads in succession to the extremities, the patch first formed healing as fresh ones appear be- low. Sometimes, however, other parts are seized first; and per- haps more frequently so when this variety shows itself in infants; for here the parts about the navel are usually first affected, and the disease winds downward to the sexual organs, which are often very considerably tumefied and inflamed. What, however, is usually de- nominated the infantile erysipelas, is more commonly a variety of gangrenous erythema, produced, in many instances, by want of clean- liness, pure air, and nutritive food. The inflammatory blush soon assumes a livid hue, and is sometimes covered with or surrounded by petecchiae : the cuticle is separated to a considerable extent from the cutis, breaks, and exposes a foul and ulcerating surface that al- most immediately passes into a state of gangrene. In some instan- ces, nevertheless, these cutaneous efflorescences are probably accom- panied with a true erysipelatous fever: for in lying-in hospitals the disease is said to have proved occasionally contagious. The erysipelas cedematodes, and e. gangranosum of Dr. Willan, appear to be misnamed, and consequently misplaced. They are more accurately" erythemata, and have already been described under the species erythema azdematosum, and e. gangrenosum. The usual causes are cold, intemperance, suppressed perspiration, and the other common excitements of fever operating upon an ery- thematic diathesis, and producing therefore this peculiar efflores- cence in connection with the febrile attack. In almost every in- stance, there is evidently a diminished vascular action ; and hence we meet with the disease far most frequently in persons of delicate habits, women, children, and those who have long resided in warm climates.

HI. to the world as a public character; but in this case the diet had, from boyhood, been exclusively that of vegetables from an extraor- dinary disgust for '.nimal food of all kinds. It is also said to have occurred in consequence of repelled gout,* suppressed menstruation,! and insolation, or exposure of the head to the mid-day rays of the summer sun.J It may possibly in some idiosyncrasies be produced by indigestible or rancid foods ; and es- pecially by shell-fishes which disagree with the stomach ; though there is reason to believe that in many cases of this kind erysipelas has been mistaken for urticaria, or roseola. From this view of the subject the general mode of treatment may be expressed in a few words. Venesection was formerly recom- mended, and has been so of late by a few writers, but upon mistaken principles. I can conceive very few cases in which it has a chance of being serviceable; and the application of leeches always exaspe- rates the etflorescence. We should first cool the body by gentle laxatives, and instantly have recourse to a tonic plan. The bark given largely, as long since warmly and judiciously recommended by Bromfield§ and Colly,|| has rarely failed of success. Dr. Fordyce was in the habit of giving it, in a dangerous state of the disease, in the proportion of a drachm of the powder every hour. He tried it for twenty years and with growing confidence. Where, however, there is much evening or night exacerbation, it may temporarily be drop- ped for some warm diaphoretic, as camphor, with small doses of James's powder, or the spirit or compound spirit of sulphuric ether, in saline draughts made with the carbonate of ammonia. If the head be much affected it should be lightly covered with linen wet- ted constantly with vinegar and cold water, or equal parts of water and the solution of acetated ammonia: and, if the vesications ooze, they should be frequently dusted with finely powdered starch, or a powder consisting of half starch and half calamine. The diet should be light and of easy digestion. Opiates have rarely succeeded in procuring sleep ; and have generally added to the mental irritation. * Stoll, Rat.

EMPYESIS. pustulous Epantftem. ERUPTION OF PHLEGMONOUS PIMPLES ; GRADUALLY FILLING WITH A PU RULENT FLUID ; AND TERMINATING IN THICK SCABS, FREQUENTLY LEAVING PITS OR SCARS. Empyesis is a term of Hippocrates, and is to be found in the fifth book of his Aphorisms. It is derived from the Greek eftiruou, or ift-rvia, " suppuro." The Greek writers also use, and perhaps more generally^ ecpyesis, from txvvov, of similar meaning. The same distinction between the terms is made in the present system as be- tween emphlysis and ecphlysis; the former being limited to signify pustular eruptions produced by internal and febrile affection, and the latter to signify those that are merely cutaneous or superficial, or with which internal affection is not necessarily associated. The genus empyesis contains not more than a single species that has yet been discovered, and that is, EMPYESIS VARIOLA. SMALL-POX. SPECIES I. EMPYESIS VARIOLA. SsmnlUftot.

There is no substantial ground for believing that the disease was known to the Greeks or Romans. It has been thought, indeed, by some persons, that the former have glanced at it under the name of anthrax;* but the idea is too wild for serious refutation. It is far better ascertained that it existed in Asia, and especially in Chi- na, for an incalculable period before it was known in Lurope ; and from the accounts of the Jesuits, to which we shall have to refer Hahn, variolorum Antiquitates e Grtrcis erutse. 1734.

[CL. ™-~°*' lU' more particularly presently, it is highly probable that the art of inoculation was practised throughout the Chinese empire, oeiore the natural contagion Had reached the European shores. About tne middle of the sixth century it is supposed to have been conveyed Iby trading vessels from India to Arabia; and there is no question that the triumph of the Arabian or Saracenic arms introduced it from Africa into the Levant, Spain, and Sicily. # . The first accurate description we have of it is contained in the Almanson of Rhazes, written about the end of the ninth or the be- ginning of the tenth century; in which, however, he quotes from an Alexandrian physician of the name of Aaron, who had written on the same subject as early as the year 622. Yet it is very singular, that neither Rhazes nor Aaron, so tar as their writings have reached us, make mention of the contagious property of the disease, chiefly accounting for it as produced by an ebullition of the blood, and particularly incident to the age between childhood and youth. And it is equally singular that it should be asserted by Aaron that the same person is liable to a return of it a second or even a third time, proecipue cum sanguis sit acutus. Has the disease undergone any change since this period so as to render those who have not had it more susceptible of its influence, and those who have had it less ? In the descriptive part of the dis- ease, little is to be added to Rhazes' statement, and, what is more singular, he recommends the cool treatment. Unfortunately, how- ever, the doctrine of concoction and despumation of the humoral pathologists spread afterwards so widely, and was so generally sup- ported, as to put to flight this correct and rational view of the sub- ject ; and every attempt was made, by warm clothing and the warm bath, to maturate the peccant matter and drive it in as large a quantity as possible to the surface ; by which the slightest cases were violently exasperated, and too often rendered fatal. The severer the disease, the sooner the pustules show them- selves, thus completely reversing the law of scarlet-fever; a re- mark for which we were first indebted to the sagacious eye of Sy- denham. And hence in the confluent variety the eruption appears on the second or third day, while in the distinct we have seldom any traces of it till the fourth, and often not till the fifth day. If a patient have accidentally become impregnated with the con- tagion of the measles before inoculation or being exposed to the contagion of the small-pox, the latter, as we have already observed, will, generally speaking, be retarded in its progress, and not make its appearance till the measles have run through their course, upon the common law that the constitution is affected only with one dis- ease at a time. But to this common law we have already pointed out various exceptions ; and as gout and rheumatism sometimes co- exist, the measles and small pox occasionally co-exist also. In the year 1769, Mr. King, of the Foundling Hospital, Dublin, inoculated forty-three children of the establishment. On the fourth or fifth day afterwards, sixteen of them sickened with the measles, and went GE. III.-SP. I.] SANGUINEOUS FUNCTION. 413 through the disease regularly, yet the progress of the small-pox was not retarded or altered ; for the pustules of the latter disease appeared as those of the former died away ; and both complaints were of a mild character: a like coincidence occurred in the ensu- ing year, and with a like favourable termination.* In this case the common law of retardation seems to have been interfered with by some peculiar constitution of the atmosphere ; for the effect was general to all who were under the influence of ru- beolous contagion. In other cases we have a like interference with the common law of variola, from the idiosyncrasy of individuals or some temporary but equally occult power operating upon the sys- tem. There are some persons who seem to possess a natural immu- nity to its influence, and pass through life without ever being infect- ed, though they may have purposely exposed themselves to the ^ most contaminated atmosphere. There are others, who, though in- capable of being affected at one time, lose their emancipation at another. " 1 know an old nurse," says Dr. Huxham, " and one apo- thecary, who for many years attended persons, and a great number too, in the small-pox, and yet never had them ; nay, many that have industriously endeavoured to catch this infection, by frequenting the chambers of the sick, have done it without effect; and yet some of these persons, some months or years after, have been seized with the small-pox."t But not only does the susceptibility of the disease vary in degree at different times and in different persons, but the irritability of the body beneath its influence. Thus among fifty persons who receive it at the same time and undergo the same regimen, we may perhaps have as many degrees of violence ; some dying beneath its severity, some escaping though with great peril, and indelibly seamed and scarred, and others evincing little fever, and a very slight eruption. The present author caught it casually in London, when a child about six years old, and passed through it with scarcely any disturbance, and not more than twenty scattered pustules. In like manner we find, under inoculation, that while, some persons throw forth a full crop, and suffer considerably from fever, others have scarcely any febrile symptoms, and no more eruption than the pustule on the puncture ; the disease, in this case, exhibiting the same change as occurs in inoculated cow-pox, compared with the exanthem as received casually from the cow. It was at one time doubted whether this slight appearance afforded protection for the future. There is now no longer any doubt upon the subject. But we may go beyond this, and reasonably conjecture, that those who have passed through the disease with but little inconvenience, are even less exposed to future attacks than persons who have had it in.the confluent form, and whose faces are marked with its ravages. For as the degree of violence depends, * Edin. Med. Comment. Vol. m. p. 443. ' Treatise on fevers, Small-pox, &'c. 414 H/EMATICA. [CL. IH.-OR. HI. where there is no error in the treatment, upon the degree of irritabi- lity, which the constitution manifests under the contagion, and as the irritability and susceptibility march with an equal step, he is most likely to have a renewal of the susceptibility in process of time, who bears the most evident marks of a greater susceptibility antece- dently. It has indeed been conceived by very distinguished pathologists that the small-pox can never be had a second time, notwithstanding various assertions in Support of this fact; and the argument is thus ingeniously put by Dr. Heberden, who was himself a disbeliever: " It would be no extravagant assertion to say that here in England not above one among ten thousand patients is pretended to have had it twice ; and whenever it is pretended, it will always be as likely that the persons about the patient were mistaken, and supposed that to be small-pox which was an eruption of a different nature, as that • there was such an extraordinary exception to what we are sure is s so general a law.'** This remark is forcible, but the actual occurrences are in many, perhaps most of the instances appealed to, still more so. For, from the cause I have just pointed out, those who have had a repetition of small-pox, have generally, if I mistake not, been able to exhibit proofs of a prior attack in pits or scars on the face, or some other part of the body, manifesting the violence with which the disease ran its course, and consequently the strong predisposition of the constitution towards it, and irritability under its influence. The medical repositories are rich in cases of this kind, some of them so striking and so well established as to prohibit all doubt whatever: and in the two or three instances which it has fallen to my lot to witness, 1 have traced the same character; for pits from the prior attack have been visible while the genuineness of the existing attack was in one instance substantiated by the test of inoculation. That erroneous statements upon this subject have been very numerously given to the world is unquestionable ; among which we can find little difficulty in placing that of Borrelli, containing the history of a woman who recovered from seven distinct attacks of small-pox, and died on the eighth; the antecedent eruptions having doubtless been those of some other exanthem or cutaneous efflorescence : but the clear and incontrovertible cases are sufficient to establish an occa- sional departure from the general law, and teach us to look without a scoff upon the assertion of the oldest Arabian writers, and particu- larly the declaration of Aaron, that the disease occasionally occurred a second, and, in some instances when there was a strong predis- position to it, even a third time. A tike deviation from the ordinary path of procedure impresses us in the history of other exanthems. The same general law prevails very strikingly in measles and scarlet-fever, but we have also a law of exceptions ; and the exceptions in one disease seem to * Medical Transactions, Vol. I. Art. xvn. GE. HI.-SP. I.] SANGUINEOUS FUNCTION. 415 hold a steady proportion to those in another. They are most fre- quent in scarlet-fever, fewer in measles, and still fewer in small-pox. In plague, the general immunity lasts but for a few weeks ; yet some who have recovered seem to be protected for a much longer time, and several for life. In influenza, it extends through the whole duration of the existing epidemy, but the susceptibility recovers itself against the next visitation. In some remittents, as yellow-fever, the patient continues little susceptible for many years, perhaps for the whole of his natural existence : in intermittents, the susceptibility, on the contrary, is very generally increased; for the man who has once suffered from an ague catches it again more readily than another. A high degree of fever is not necessary to emancipate the system in any exanthem ; and consequently not in small-pox. It is upon this principle that inoculation takes its stand in vaccinia as well as variola. Febrile commotion, as we have observed already, though necessary to throw the morbid poison to the surface, is necessary only in a small, and sometimes an almost imperceptible degree ; and if it be urged beyond this, the morbid poison will be increased in quantity, the ferment will acquire a wider assimilation ; and hence the fever and the eruption always maintain a balance. Provided the entire system submits to the influence of the contagion, the emancipation is always as perfect under a small product as under a large ; and itis wonderful to observe how completely this influence extends through every part of the system, often indeed without any disturbance whatever, upon a deposit of the minutest particle of variolous contagion under the cuticle; for we are perpetually witnessing cases, or rather were, when variolous inoculation was more frequent, in which a full change has been operated on the entire frame, though the only pustule has been that excited at the puncture ; and the individual, before liable to the disease, is become liable no longer. And that the blood itself, and therefore every particle of the blood, is equally influenced in such circumstances, and even charged with the nature of the virus, is obvious from the frequent communication of Jthe disease from a pregnant woman to the fetus; and this too at times where the mother is no sufferer from the disease herself. A remarkable example of this last fact is given by Dr. Mead in the following words: " A woman who had formerly had the small-pox, and was near her reckoning, nursed her husband who had caught it. At her full time she was delivered of a dead child, whose body was covered over with pustules; a manifest sign that it died of the small-pox before it was brought into the world."* Mauriceau has another case or two to the same effect :t and others have occurred since, and are noticed in several journals of later date. * De Variolis, Cap. iv. : Sur la Grossesse, et d'Accouchement des Femmes. Obs. 600. et 576. 416 H KMATICA. [CL. IH.-OK. HI. In these cases there is no assimilation or multiplication of morbid leaven ; an influence is indubitably exercised, and that, too, over the entire current of blood; for it could not otherwise reach the fetus, yet without any sensible effect on the mother. What is the nature of this influence ? is it by an infinitesimal division of the minute drop of contagion inserted into the skin, or that received by the breath ? Whatever be the way, it enables us to be less surprized at the mode by which family taints, as gout, scrophula, and phthisis, are transmitted from generation to generation. Unborn infants do not always receive the small-pox under the same circumstances, nor in every instance even where the pregnant mother sickens with the disease. Sir George Baker, who was indisposed to credit these singularities, refers to two instances in which the mothers having been inoculated had passed through the eruption favourably, and brought forth infants both of whom three years afterwards were also inoculated with good effect.* From all which we collect, and we can do more, that a like variation occurs before birth, as we have just observed occurs afterwards; and that different individuals, or even the same individual under particular circumstances, evince a different degree of susceptibility ; so that the contagion, though resisted at one time, is readily received at another. There is another feature in the physiology of small-pox, that is peculiarly worthy of notice ; and that is the power which all deep- seated organs possess of opposing a lodgement of the pustulous inflam- mation on their own surfaces, and driving it altogether externally where it can do least mischief. Dissections have abundantly shown that the viscera and cavities of the interior are never affected with the eruption, except such as, like the skin, are exposed to the approach or ingress of air, as the nose, mouth, trachea and its ramifications. and the entrance of the meatus auditorius. As a general rule, pustules are never found in the rectum, but if there be any pro- lapse, and the sphincter be exposed to the contact of air, that part of the rectum, which concurs in the exposure, will share in the common fate of the external parts. To what extent variolous contagion is capable of radiating, as it issues into the atmosphere from a diseased body, has never been satisfactorily determined. In laying down the general rules of febrile miasm, I ventured to state that contagion or miasm vene- rated in the living body, does not appear to be very volatile in any instance, and soon dissolves in a pure atmosphere. The conta- gion of small-pox seems fully to be governed by this law. When small-pox was more frequent than at present, medical practitioners, though passing casually from house to house, were rarely, if ever, accused, of communicating the disease; and Dr Haygarth has appealed to an evidence of facts in proof that the sphere of vario- lous contagion does not include a diameter of fifteen hundred feet, and probably not a hundredth part of such a diameter. * Med. Trans. Vol. n. Art. xix. OE. IH.-SP. I.] SANGUINEOUS FUNCTION. 417 As the susceptibility of small-pox varies so considerably in dif- ferent individuals, it is not to be wondered at that the irritability of the system to its influence should vary also, and consequently that there should be some difference in the period of time between the supposed communication of the disease and its appearance by any manifest tokens. Upon the whole, the interval may be calculated to vary from six to twenty-one days in the natural small-pox ; and in the inoculated, which anticipates the action a day or two, from four days to eighteen. The writers of this disease have subdivided it into an endless multiplicity of forms: but the four following varieties are sufficient to include the whole : x Discreta. Distinct small-pox. C Confluens. Confluent small-pox. y Degener. Crystallized-pox. Horn-pox. 3 Inserta. Inoculated small-p*ox. The pathognomic characters of the first variety or distinct small-* pox are the following : Pustules pea-sized; distinct, distended^ circular; the intervening spaces red; the fever ceasing when the eruption is complete. The disease opens its battery with the usual signs of a febrile cold fit, accompanied with vomiting, and some degree of soreness in the throat. About the fourth, sometimes on the third day, the eruption begins to appear on the face, neck and breast, in minute, flea-bite spots, which multiply every night for the ensuing four days, when there is usually a pretty furl crop of them over every part of the body, though the face is, in almost dll cases, far more covered than any other part; and that, according to M. Camper in the proportion of five to one.* The head, face, hands and wherever else the pimples show themselves gradually swell, and the eye-lids are often so much distended as to close the eyes and produce blind- ness ; the spaces between the pimples are reddish, and continue to grow redder as the pimples become pustules and maturate ; the fever is of the caumatic or inflammatory kind, and the suppuration is complete on the eighth day or thereabouts. On the eleventh, the inflammation and pustules manifestly abate, and the latter, measuring the diameter of a pea, dry away by degrees and scale off, and wholly disappear on the fourteenth or fifteenth day, with the exception of those on the extremities, which, as they came out later, commonly continue a short time longer. Such is the ordinary course : but the symptoms vary greatly in severity, according to the degree of fever, and extent of the erup- tion, which, as already observed, hold a pretty accurate balance. Where the pimples are few and scattered there is but very little indisposition; but where they are very numerous, though still dis- * Les Avantages de llnoculation, Sic. Paris, 1782. it 53 418 H^MATICA. [CL. HI.-OR. HI- tinct, the soreness, swelling and febrile heat are very distressm and under this form the progress of the disease has often been divi- ded into four stages, an incursive, an eruptive, a maturating, and a declining or scabbing, at each of which it discovers an exacerbation of pyrectic svmptoms. And when the patient is an infant, it is at these times, and especially on the incursion of the disease, occa- sionally attacked with a convulsion fit, or perhaps several in succes- sion, which it was once the custom to make much lighter ot than the occasion justifies. The grand principle in the treatment of small-pox, as ot all the other exanthems that have past before us, is to moderate, and keep under the fever; and, however the plans that have been most cele- brated for their success may have varied in particular points, they have uniformly made this principle their pole-star; and have con- sisted in different modifications of fresh air, cold water, acid liquors and purgative medicines : heat, cordials, and other stimulants hav- ing been abundantly proved to be the most effectual means of ex- asperating the disease, and endangering life. Dr. Mead seems to have been almost indifferent as to the kind of purgative employed, and certainly gave no preference to mercurial preparations. His idea was that all were equally beneficial that would tend to lower the system : " Indicium," says he, " certe satis manifestum, quamcunque materiae diminutionem, fomitem igni sub- trahendo, huic morbo apprime convenire." And in this manner he accounts for the mildness of the disease after any great evacuation, . natural or artificial; after acute diseases, immoderate catamenia, child-birth, and salivation. Mercury, however, appears to have a specific influence upon the action of variolous matter; perhaps, as in the case of syphilis, upon the quality of the matter itself: for though, when considerably dilut- ed with water, it is still capable of propagating the disease by in- oculation, yet Von Wensel has shown satisfactorily that when tri- turated with calomel it loses its energy, and in inoculation becomes inert and useless. Mercury has hence been denominated in Ger- many, remedium pancreston, and has certainly supported its charac- ter as the best corrector of the small-pox we are acquainted with from a period antecedent to the introduction of inoculation into Eu- rope, to the present day. " Physicians who attend hospitals," says Sir George Baker, " have frequently observed the small-pox to be particularly mild in those patients who have happened to receive the infection soon after a mercurial phyalism; and inoculation is said to have been a much more successful practice in some of our American colonies since the use of calomel has been there introduc- ed into the preparative regimen." When given merely as a pur- gative it is usually mixed with the powder or resin of jalap, and in this manner acts much more briskly. Exposure to fresh and cold air is nearly, if not altogether, of as much service as calomel; and hence the patient, however inactive and dejected he may be, should be roused from his bed, and urged GE. IH.-SP. I.] SANGUINEOUS FUNCTION. 419 to use gentle exercise either abroad or in a cool capacious room. Cold water is usually prescribed in large draughts for the same pur- pose, and very generally proves highly refreshing. The acids, and especially the diluted mineral acids, have a peculiar influence in diminishing the extent of the eruption ; insomuch that some inocula- tors have been bold enough to prophecy the number of pustules a patient would produce under a given quantity of the acid. Wheth- er any one of the acids has an intrinsic power beyond the rest has never been sufficiently put to the test of inquiry; nor is it clearly ascertained in what way they operate towards the present effect. They are an excellent refrigerant in fevers of all kinds, but in small-pox there seems to be a something beyond this power, and they probably restrain the process of assimilation. Lemonade may conveniently form the common drink during the fever; or a solution of cream of tartar in water, which, as tending to keep the bowels gently open, will be preferable. When the fever is considerable, the purgative should be repeated at each of its exacerbating stages; and if convulsion-fits arise, the spasmodic irritation is best removed by laudanum. The pathognomic characters of the confluent variety are the following :—Pustules confluent, flaccid, irregularly circumscribed : the intervening spaces pale : with great debility. In this variety the eruption assumes, at first, the appearance of a general efflorescence without any distinctive points; innumerable pimples, however, show themselves about the third day, being a day or two sooner than in the discrete variety. They soon coalesce from their thronging number, and become filled, not with pus, but a yellowish serum, for this variety seldom suppufates regularly. The fever is violent and exhibits a synochous or typhous type ; and, in- stead of subsiding on the appearance of the eruption, as in the dis- tinct variety, very generally increases. The head is oppressed, the eyes inflamed, the brain comatose or delirious. After the eighth day the detached pellicle, covering a large secretion of this virulent fluid, becomes brown, and not yellow as in the distinct sort. Peculiar to the confluent small-pox is salivation in adults, and a looseness in children ; the former always attends ; the latter more rarely. The spitting begins as soon as the eruption appears or within a day or two afterwards: the saliva is at first thin, and easily and plentifully discharged ; but, towards the eleventh day, which is the period of the greatest danger, it becomes viscid and is discharg- ed with great difficulty; the looseness in children, however, con- tinues beyond this period. When the disease terminates favourably, the swelling of the face about this time begins to abate, and that of the extremities com- mences. But, if the. constitution be incapable of counteracting the weakness under which it is suffering, or the mass of disease with which it is oppressed, and particularly the exacerbating or seconda- ry fever, as it is called, which takes place at the stage of matura- tion, the cuticle suddenly becomes flattened, the features sink, tho 420 H/l.MA l tCA. [CL. IH.-OR. III. pustules are depressed; the coma increases, flea-bite spots are sprinkled over the body, succeeded often by hemorrhages from dis- solved blood; the pulse flutters and the patient expires; usually, as already observed, about the eleventh, but sometimes not till the sixteenth day. In the commencement of this variety, the same reducent plan is to be pur-ued, as already recommended in the preceding variety ; and the effusion of cold water may be added to a free use of fresh and even cold air. Bleeding is a doubtful remedy, and its propriety must entirely depend upon the constitution or habit of the indivi- dual, and the nature of the prevailing epidemy. In a state of high entonic health, and firm elastic fibre, it may be allowed, and per- haps repeatedly: but we should always bear in mind, first, that the plenitude of the disease does not so much depend upon the strength or weakness of the frame, as upon i s susceptibility of the contagion, and irritability beneath its action : and next, that in con- fluent small-pox the process of maturation does not take place kind- ly or perfectly, and that the fever, often a synochus, has always a tendency to run into a typhus, particularly when the temperament of the atmosphere predisposes to this type. On this account, it will often be found necessary, and particularly towards the stage of ma- turation, to support the tone of the system instead of reducing it. Camphor offers us one of the medicines for this purpose ; and may be given in solution or in the form of pills. The latter is generally the most convenient, as it can thus be taken in a larger quantity, and needs not interfere with volatile neutrals, etherial compounds, the acidulated decoction of cinchona, or the same tonic in a more powerful form. If, indeed, on the accession of the secondary fever, the pulse should suddenly sink, the pustules flatten, and the surface turn pallid or purple, wine must be added to the other remedies, blisters or sinapisms applied to the feet or legs; and opium be ad- ministered if a diarrhoea should supervene: though in the earlier stages of the disease this last symptom should be very cautiously in- terfered with. Some part of the secondary fever may probably be set down to the score of the absorbed virus, now thrown back upon the blood from every part of the surface ; and to disarm this source of exacerbation, it may be convenient to open the pustules as they ripen, and let them discharge their contents externally. And to save the face as much as possible from those exulcerations of the true skin that terminate in pits and scars, a mask of fine linen or cambric should be worn over it, illined with cetaceous cerate to soften the integument and defend it from the air. Small-pox, then, may well be contemplated as a fearful disease. It is so at all times from the uncertainty of its prognosis; but espe- cially when it assumes a severe character. And it is so, moreover, not merely on account of its own ravages, but of the tendency it pro- duces to subsequent evils, after its own course has subsided. In many cases the constitution is incapable of recovering from the general disturbance and debility it has, introduced, and hence atro* GE. HI.-SP. I.] SANGUINEOUS FUNCTION. 421 phy, dropsy and hectic are by no means uncommon results. But it more frequently proves mischievous by stirring up some heredita- ry taint that might otherwise lie quiet through life; and in this way becomes an exciting cause of scrophula, consumption, and gout. The horn or crystalline-pock, it is only necessary to notice, as forming a somewhat singular departure from the usual course of the disease, though not often accompanied with danger, or distinguish- ed by an overloading eruption. Its pathognomic characters are set down in the Nosological Synopsis as follows : Pimples imper- fectly suppurating; ichorous or horny; and semi-transparent. From some unknown cause, the variolous fluid is, in this variety, secreted and thrown upon the surface in the form of lymph, and is never exchanged for that of pus. As the finer part of the fluid is absorbed it loses its pellucidity, and the vesicular pimples appear whitish, and preserve this hue till they dry and peel off. This is particularly the case in persons of a fair and delicate skin, but, where the skin is darker or coarser, they become brown, hard and horny: and hence it is always in this way that the present variety terminates amongst negroes. Whenever small-pox occurs a second time, it usually shows a tendency to this modification. The fourth variety under which small-pox is to be found is the artificial modification known by the name of inoculation : a most im- portant advantage to mankind before they were acquainted with the equal or nearly equal protection afforded by the virus of cow-pox. Its peculiar characters are thus described in the volume of Noso- logy : Orange-coloured aveola about the puncture ; pain in the axilla about the seventh day : disease mostly mild ; and the purulent discharge sometimes confined to the punctured parts. This mode ,of communicating the disease, like the natural disease Itself, appears to have reached Europe from the east, and especial- ly from China, where, according to the statements of the Jesuits,* it has been practised immemorially by perhaps the simplest and best means of communication that has hitherto been devised, that of a needle charged with the contagious matter of a pustule, and intro- duced transversely under the cuticle. From China the discovery appears to have travelled into India, and thence to Asia Minor. Its first employment in our own country seems to have been the result of some fortunate observation, made, like that of cow-pox inoculation, in the rudest parts of it; for the practice of " buying" the small- pox, which was in fact a communication of the disease by insertion, was prevalent in Wales at a very early period, and appears to have been also occasionally resorted to in the Highlands of Scotland, from an antiquity nearly as remote ; of which abundant proofs are to be found in various articles in the Philosophical Transactions.! All such practice, however, and even the knoweldge of it, seems to *Lettres Edifiantes et Curieuses, &c. passim. See Vol. xxxii, years 1722-3, and especially Dr. Williams's account, 422 HjEMATICA. [CL. 1II.-OR. III. have been confined to the remote quarters in which it accidentally arose, as late as the year 1721, when Lady Mary Montague who had witnessed its success in Turkey, and had had a son successfully inoculated there, submitted an infant daughter to the same process at this time in London. Yet so little acquainted with its success were the public, and even the medical profession, at this period, and so cautious in giving it credit, that an experiment of Its effect was ordered to be made in the same year on six condemned crimi- nals, allot*whom were fortunate enough to recover, and who thus redeemed their lives. This gave countenance to further attempts; yet the innovation, like that of inoculation from cow-pox, was sharp- ly and pertinaciously opposed, and not more than seven hundred and sixty-four persons, according to Dr. Jurin's calculation, were inocu- lated all over England from 1722 to 1727. Unfortunately the practice of treating the diseaae with cordial* and a hot regimen at this time prevailed, and was too generally ap- plied to the inoculated as well as to the natural process, by means of which the former was often rendered a severe and in many cases a fatal disease; though it was impossible for the dullest intellect to be altogether insensible to its high comparative advantages. By de- grees, however, the refrigerant and reducing plan obtained a tri- umph, and the triumph of inoculation was a synchronous step. Yet half a century afterwards the exploded plan was still persevered in by some practitioners, and it is instructive to mark the comparative mischief that still accompanied it. " I found," says Sir George Ba- ker, writing in 1771, " that in the counties of Essex, Norfolk, and Suffolk many thousands of people, of all ages and constitutions, and some of them, of every apparent disadvantage, bad been inoculated with general good success; whereas at Blandford, in Dorsetshire, out of three hundred and eighty-four, who were inoculated, thirteen actually died, and many others narrowly escaped with their lives from the confluent small-pox."* This gives us a direct mortality of something more than one in thirty; and it is almost needless to add, that in the successful districts here alluded to, the cooling plan was prevalent, and at Blandford that of hot beds and a warm regimen. Even this result, however, with all its fatality offers a wonderful improvement upon the march of natural small-pox ; in which one out of every three or four have been computed to die among adults, and one out of every seven among infants ; while, wherever the cool- ing and reducent plan has co-operated with inoculation, the casual- ties are not more than one in five or six hundred. Yet great as is the intrinsic advantage of inoculation even upon its lowest scale, there is one evil which has always accompanied it, and which, in a nation so justly proud of its civil liberties as Great Britain, it is almost impossible to provide against; and that is the wider diffusion of variolous contagion through the atmosphere * Med. Trans. Vol. n. Art. xix. Compare M, Gatti's JN'ouvelles Reflexious suv la Practique de l'lnoculation. Paris 1770. GE. IlI.-SP. I.] SANGUINEOUS FUNCTION. 423 by the indiscriminate use of inoculation in all places. And hence it has been very forcibly observed in our own day by those who have written most warmly in favour of vaccination, that small- pox inoculation is upon this ground a greater public evil than good; since the multitude who will not consent to be inoculated, receiving the natural disease more generally than they otherwise would do, the total mortality is greater than before inoculation was had re- course to. I was at first induced to think that this statement was a little too highly coloured for a particular and present purpose. But on turning to Baron Dimsdale's tables of calculation drawn up nearly fifty years ago, I find him arriving at the very same conclusion ; and we fairly affirm, that the deaths from small-pox, since the intro- duction of inoculation, have increased in consequence of the more extensive diffusion of variolous contagion in the proportion ot four- teen or fifteen upon every hundred. The bills of mortality indeed give us something more than this. By what means variolous contagion received by a puncture be- comes so much milder than when received from the atmosphere is a problem that has never been satisfactorily solved. Something is unquestionably due to the preparatory progress of purgatives and a reducent regimen; but, as the same mildness of character does not obtain in the natural disease, where the same preparation has been submitted to antecedently, some other power must be sought for. Under inoculation, and with the usual precautions, the eruption is commonly distinct and widely scattered; yet the most striking cha- racter in the inoculated form is that when the eruption is full, and even confluent, the secondary fever, so alarming in the natural dis- ease, is here for the most part slight, and sometimes altogether ab- sent. This exacerbation is usually ascribed to an absorption of the contagion from the pustules; but the feature before us shows that there must be a something distinct from absorption, though perhaps acting in union with it. Is the virus from the first less irritant, and less capable of exciting much secondary fever, for the very reason that it was less capable of exciting much primary ? It is on this account that variolous inoculation may be submitted to, without danger, by feeble infancy, advanced age, and even ca- chectic habits in every stage of life; and that the season of the year does not seem to be a matter of great importance. Pregnant women, however, ought never to be exposed to it, nor infants, where there is a choice, till after the irritation of teething. The operation is perfectly simple; the needle originally employ ed in the East is as good an instrument, as any, though the lancet is preferred in general. It is only necessary to deposit a minute drop of the contagion under the cuticle, or at least to make such a wound as may give forth a single drop of blood. It is preferable to take the fluid before the pustule suppurates; as afterwards it seems to partake of the nature of common pus as well, and produces a lar- ger circle of inflammation, and on this account also it cannot so fully be relied on. The puncture does not so completely disappear as in 424 H.EMATICA. [CL. III-OR. III. that with vaccine fluid, but it is often scarcely visible for three or four days. At this period, a minute papula may be traced, a little itching is felt, and sometimes there is a slight inflammation. On the sixth day, a pain and weight are felt in the axilla, proving that the lymphatics of the arm have become affected, and that the virus is conveyed into the system. On the seventh or eighth day, the precursive symptoms of transient shiverings, head-ache, and pain in the back are perceived, and immediately followed by the erup- tion itself; though in this mild form of the disease the only erup- tion, as in, the inoculated vaccinia, is the pustule on the puncture or a few which directly surround it. Where the disease spends it- self in this manner the local efflorescence commonly spreads over a larger area than otherwise, and the adjoining lymphatics participat- ing in the irritation, the tenderness and sense of weight are increas- ed in the axilla. Where the symptoms are unfavourable there is a purplish, instead of a rosy inflammation, or a narrow, deep red, cir- cle surrounding the puncture, with a dip or depression in the pus- tule. The treatment is to be the same as that already pointed out for the natural disease : but it should vary with habit, constitution, or age of the individual. Sufficient attention was not always given to this remark formerly: for the preparatory regimen was a bed of Pro- crUstis to which every one was alike compelled to adapt himself. Sir George Baker openly complained of this inconsistency in his own day;* but it was very generally continued notwithstanding his censure. GENUS IV. ANTHRACIA.

IV.] SANGUINEOUS FUNCTION. 425 among the nosologists, as to the proper station of both these species; many contending that plague ought not to be regarded as an exan- them, and most writers having hitherto contemplated yaws as an impetigo, or some other dysthetic affection. Dr. Cullen has expres- sed a doubt whether the first should not be removed from the order of exanthems into that of fevers ; Vogel has actually introduced it into this last order; Willan has rejected it from the exanthems. Parr arranges it as an exanthem, in his article Nosology, having pre- viously, like Willan, rejected it from that division in his article Cutanei Morbi. In his remarks subjoined to the article Nosology, he again acknowledges that " on reflexion it appears improper" to introduce it into the list of exanthems ; and in his article Pestis, he asserts more roundly that " there is no foundation for arranging plague amongst the exanthemata ; and that it should be reduced to the asthenic remittents. Sauvages, Linneus, Sagar, and Macbride have entered it in the order in which we have placed it in the pre- sent system. In few words, there appears strong and almost incontrovertible reason for thus placing it. The fever, as will presently be shown, is eruptive, and as specifically so as that of any of the exanthems; it is contagious like most of them ; and, although frequently occurring oftener than once in a man's life, we have the concurrent testimony of all the writers, who have been eye-witnesses of its effects, that it renders every one less susceptible for a certain period afterwards, and some for the whole term of their existence. With respect to yaws, the diversity of opinion has been quite as considerable as that respecting plague. Generally speaking, it has been placed in the loose and indeterminate class which has been dis- tinguished by the name of cachexies; Sauvages and Sagar arrange it in the order tubera of this class; Cullen in that of impetigines. These writers take little or no notice of any kind of febrile features that accompany it whether specific or sympathetic. Dr. Young pays as little attention to the febrile symptoms by which it is said to be distinguished, and at the same time transfers it from the division of cachexies (cacochymioe as he denominates them) to the order of paramorphiae or structural diseases. Dr. Winterbottom, and Dr. Dancer, on the contrary, contend that a slight fever is its primary symptom; and Dr. Ludford, to whom we are indebted for, per- haps, the best history which has yet been given of this disease, de- scribes it as a proper eruptive fever, totally unconnected with diet, lues, or any other taint in the blood ; commencing with alternations of shivering and heat, lassitude, want of appetite, and pains in the head and loins to so great a degree as to prevent sleep; the fever and every inconvenience diminishing after the eruption, and the ap- petite returning. So that, like small-pox, it appears to have a re. gular accession, height and decline; and, as already observed, may be propagated by inoculation; and is never known to occur a second time. Hence Parr, who seems to have long wavered in his opinion concerning the real nature of this disease, regarding it at one time vol. n» 64 426 HjEMATICA. [CL. IH.-OR. Ill, as a pustulous exdnthem, and afterwards^ as a mere cuticular intumes- cence, returned, at last, with a decided mind to his first opinion, and again asserts that " the detail of symptoms shows that the disease is truly exanlhematous." This view of the subject will therefore abundantly justify the present arrangement of both these diseases ; support their preten- sions to the character of carbuncular exanthems; and consequently develope the nature of the connection of yaws with plague, under a nosological method founded on the principle of symptoms. In their individual or specific characters they are indeed highly discrepant, but this is not sufficient to call for a separation, while they agree in the common outline that may form the basis of a generic division. The tall and stately acacia of Egypt and the delicate sensitive plant of our own green-houses belong to the same genus in botany, how- ever inaccordant they may appear to the eye of an ordinary spec- tator.

TUMOURS BUBONOUS, CARBUNCULAR OR BOTH; APPEARING AT AN UNCER- TAIN TIME OF THE DISEASE : FEVER A MALIGNANT TYPHUS, WITH EX- TREME INTERNAL HEAT AND DEBILITY : CONTAGIOUS* It is happy for us, that, in describing this dreadful scourge, we are under the necessity of referring to foreign countries, or to remote periods in the history of our own, before the great advantage of public cleanliness and ventilation in our streets was sufficiently at- tended to or even known. The earliest visitation of the plague that occurs in English history was in the year 430; the last time it ap- peared as an epidemic was in 1665, and the last notice of it in the bills of mortality was in 1679. In Edinburgh it has not prevailed since 1615. From the diversified and clashing accounts that are given of this disease by different writers and eye-witnesses in different ages, or different parts of the world, we are justified in laying down the three following varieties; which, while they offer the chief points of dis- crepancy, will be found in their explanation to reconcile the seem- ing discordancies of established authorities. x Fructifera.

The body covered over with trails oi Erythematous plague. vesicular erythema, producing deep, J sanious, and gangrenous ulcerations as it spreads, often to the loss of one or more limbs. The whole of these varieties have sometimes been exhibited in the same epidemic ; the last, however, is the least frequent, wheth- er alone or in conjunction with the rest. All of them appear to have been present and intermixed in the Aleppo plague of lbbO-W, so clearly and strikingly described by Dr. Patrick Russell, physician at the time to the British Factory established at that city, tor he speaks of the pestilential eruptions appearing under the form ot bu- boes, carbuncles, or other exanthemata : among which last he takes particular notice of an erysipelatous redness forming streaks of a reddish purple or livid colour, intermixed with vibices and wheals, or large blue and purple spots, the maculae magnae of authors; while, in some cases, he observes that an extraordinary concurrence of these eruptions took place, which, however, was chiefly remarked among children under ten years of age. In the Barbary plague of 1799 and 1800, so fully and excellently desoribed by Mr. Jackson,* who was an eye-witness to its effects,— the first and second of the two varieties here offered, the fructife- rous and infructiferous, were intermixed, while the erythematic seems to have been absent. It was probably absent also in the plague of Moscow of the year 1771, as it is not [noticed by Dr. Mertens, who gives a full description of both the other modifications. In the London plague of 1665, all of them seem to have occurred occasion- ally ; the first and the second, however, most frequently, examples of which are to be found in Hodges, Sydenham, Sir Gideon Harvey,t and indeed all the writers; while, in allusion to the last, Sydenham compares the inflammation of the plague, as it often appeared, to that of an ignis sacer,'by which he means an erysipelas; in which, nature, he tells us, expels the matter of the disease from the blood to slightly elevated tumours dispersed over the surface in broad red patches: only that this ignis, says he, is more violent than the ignis, sacer ;t—" ignis noster isto sacro longS divinior est." In the plague of Athens, on the contrary, as described by Thucy- dides and Lucretius, we are not sure of the existence of buboes, as not being distinctly noticed, though probably included in the inflam- mations that are stated to have fallen upon the privities (t* «<&»«,) *■ Account of the Empire of Morocco, &c. 4to. 1809. t City Remembrancer, passim. X Febris Pestilens, et Pestis Opp. Sec. u. Class n, 428 HJSM^TICA. [cl. iii.-or. hi. while the last two varieties were perpetually intermixed; the chief eruption, however, being that of %he vesicular erythema, the sacer ignis, or holy fire, as observed by Sydenham. In consequence of which, Thucydides tells us, that « the surface of the body was nei- ther violently hot, nor wan; but reddish, livid, and covered over with an efflorescence of minute vesicles and ulcers,"—^xvxrxtvxif fitx^xti xxt tXxtrti:—but that the interior parts were so burning that the sick could not endure the lightest covering or clothes, and ea- gerly threw themselves into cold water. And he adds, that the dis- ease, in its ulcerative progress, commencing in the head or the up- per parts of the body, migrated over the entire frame, and often fixed itself permanently on the sexual organs, the hands, or the feet.* The whole of which course is by Lucretius described under the express name of sacer ignis, or holy fire. Et simul, ulceribus quasi inustis, omne rubore Corpus, ut est, per membra sacer quoin diditur lGNiS.t The entire passage precisely corresponds with the character of the erysipelas pestilens of Lorrain, delineated under this name by Sauvages, who has copied freely both from Sydenham and Hoff- man ; but which, though he calls it an erysipelas, had, as he admits, the closest affinity with plague in its most malignant form, " cum atrocissimo morbo pestilenti summam affinitatem habet;" and which was in reality this disease in the form before us. u Each," says he, " commences with horror, burning heat, delirium, prostration of strength, vehement pain of the back and head ; in each the burning matter of the disease breaks forth on the fourth day on the axillary or inguinal glands, and spreads to the feet in the form of the ignis sacer: in the glands it produces abscesses; in the extremities, gan- grene." It is the mal des ardens of the French writers ; and, in its malignant variety, the erysipelas gangrenosum of Willan. Much of this difference, however, seems to be. dependent upon local or acci- dental circumstances, and especially upon the state or constitution of the atmosphere. Thus we are told by Sir James M'Grigor, that when the disease first broke out in the Indian army in the course of its laborious expedition to Egypt, the cases sent from the crowded hospitals of the 61st and 88th regiments were, from the commence- ment, attended with typhous symptoms : while those from the Ben- gal volunteer battalion and the other corps encamped near the marshes of El-Hamed, evinced uniformly an intermittent or remit- tent type ; and those that occurred in the cold and rainy months of December and January, an inflammatory character; after which, as the weather became warmer, the disease at Cairo, Ghiza, Boulac, and the isthmus of Suez, wore the form of a mild continued fever.t * Hist. Lib. ii. 50. t De Rer. Nat. vi. 1164. J. Medical Sketches of the Expedition, &c. OE. IV.-SP. I.] SANGUINEOUS FUNCTION. 429 The plague of London in 1665 was, in like manner, distinguish- ed by a peculiar constitution of the atmosphere, which excited an epidemic synochus of great violence and danger, often accompa- nied with symptoms or rheumatism or pleurisy, and which seems to have added considerably to the progress and mortality of the plague. Sydenham expressly calls it a pestilential fever, febris pestilentialis; and adds, that the fever of the plague, after it had broken out, so completely assimilated itself to its character, that in the second or infructiferous variety it was extremely difficult to distinguish be- tween the one and the other.* In like manner Thucydides expressly tells us that whatever inci- dental complaint any person was labouring under during the plague at Athens, it was sure to run into this disease, which swallowed up every other. Yet, he adds that at the commencement of the plague complaints of all kinds were peculiarly uncommon; insomuch that by the acknowledgment of every one the year seemed to have en- joyed a general immunity.f The plague at London first attracted attention about Midsummer, and augmented in its destructive ravage till the autumnal equinox, at which time about eight thousand died within the bills of mortal- ity in the space of a week, though two thirds of the inhabitants at least had fled into the country to avoid infection. From this time it suddenly put on a milder character and made fewer attacks, nearly ceased with the cold of the winter, and totally vanished in the spring: the epidemic fever, nevertheless, remained for a twelve- month longer, though this, also, was both less common and less virulent. The same controlling circumstances take place all over the world; and in studying the history and progress of the disease we must al- low for the changes they effect. Dr. Mertens has well described this progress in the plague of Moscow of 1771, at which time he pre- sided over one of the largest hospitals of the imperial capital, and was an eye witness to its ravages.^ Having noticed its liability to modifications from the above causes, he tells us, that in general it begins with head-ache, giddiness, horripilation, prostration of strength, fever, nausea, vomiting, redness of the eyes, a dejected countenance, and a white foul tongue. A tickling attended with slight pains, is perc-ived in the parts where the buboes and carbun- cles afterwards break out. " The former," says he, " are glandular swellings, not acutely painful, and more or less elevated; usually seated in the groins or arm-pits, but occasionally occurring in the neck, cheeks, and other organs of the body." The latter he de- scribes very nearly in the words already employed in the specific definition of the carbuncle or anthrax in the preceding pages of this * Sect. n. Cap. i. t Hist. Lib. u. 49.

IH. work, though he observes, that " in the plague this tumour evinces somewhat less prominence, pain, and inflammation, than when it arises as an idiopathic affection." ""Many," he tells us, " died on the first or second day of the at- tack, before either of these kinds of tumors made their appear- ance." In such cases, an eruption of petecchia?, macula; or vibices, like what occur in putrid fevers, usually took place a few hours be- fore death; but sometimes the disease was so sudden as to outstrip the march of these active precursors of dissolution. Almost all who died were cut off on or before the sixth day : insomuch that those who reached the seventh were pronounced to be out of danger. The disease was introduced into Moscow by a communication with the Turkish army: it made little progress during the earlier part of the year, but became fearfully fatal with the advance of summer, and gradually died away with the frost. The mortality was tre- mendous. Seventy thousand inhabitants were cut off in a few months, twenty-two thousand in a single month, and sometimes twelve thousand in twenty-four hours. Notwithstanding which, by cautiously blocking up every avenue, except one, to the large hos- pital over which he was appointed physician, and keeping a strict and constant guard at the entrance thus left open, although the build- ing was in the midst of the city, it was maintained perfectly free from infection, while the disease raged around it in every quarter. Mr. Jackson's account of the plague at Morocco is in perfect con- sonance with this description, though it contains a feature or two in addition, which probably became more prominent from the high- er temperature of the atmosphere. " The symptoms of this plague," says he, " varied in different patients; the variety of age and con- stitution gave it a like variety of appearance and character. In some it manifested itself by a sudden and violent shivering, in others by a sudden delirium, succeeded by great and unquenchable thirst. Cold water was eagerly resorted to by the unwary and imprudent, and proved fatal to those who indulged in its momentary relief. Some had one, two, or more buboes, which formed and became often as large as a walnut, in the course of a day; others had a similar number of carbuncles ; others had both buboes and carbun- cles, which generally appeared in the groin, under the arm, or near the breast. Those who were affected with a shivering, having no bubo, carbuncle, spots (vibices or maculae latae,) or any other disfi- guration (eruption,) were invariably carried off in less than twenty- four hours ; and the body of the deceased became quickly putrefied, so that it was indispensably necessary to bury it in a few hours after dissolution. " The European merchants shut themselves up in their respec- tive houses, as is the practice in the Levant. 1 did not take this precaution, but occasionally rode out to take exercise on horseback. My daily observations convinced me that the epidemy was not caught by approach, unless that approach was accompanied by an inhaling of the breath, or by touching the infected person." CE. IV.-SP. I.] SANGUINEOUS FUNCTION. 431 This last remark is in strict agreement with the observations of the best medical writers of modern times who have witnessed the disease in different countries and climates: and the wholesome prac- tice of drawing a line of demarcation, and thus cutting off all com- munication with the sick, is founded upon the same view. M. As- salini traces the progress of the plague among the French army in Egypt with great care, and asserts that even those who associated with the sick were seldom infected unless inmated in their rooms: and instances the small degree of danger there is from casual intercourse, by showing how very rarely the medical attendants suf- fered. Yet fresh persons are far less safe than the stated inhabitants of an iufected place, who have been gradually inured to the influence of the morbid miasm. Families, says Mr. Jackson, who had retired to the country to avoid the infection, on returning to town, when all infection had apparently ceased, were generally attacked and died.. After the mortality had subsided at Mogadore, a corps of troops ar- rived at the city of Terodant in the province of Suse, where the plague had been raging, and had subsided: these troops after re- maining three days at Mogadore, were attacked with the disease, and it raged exclusively among them for about a month, though they were not confined to any particular quarter, many of them having had apartments in the houses of the inhabitants of the town. As in the plague of Athens and of London, continues the same author, " the mortality was so great that the living noi having time to bury the dead, the bodies were deposited or thrown together in- to large holes, which when nearly full, were covered over with earth. Young, healthy, and robust persons with strong stamina, were, for the most part, attacked first, then women and children ; and, lastly, thin, sickly, emaciated, and old people." The depress- ing passions of fear and grief had also a strong predisposing effect: a few suffered twice. Morocco lost a thousand upon an average daily, where,the infection was at its height, being about the maximum that fell at London ; Old and New Fez, from twelve to fifteen hun- dred : Terodant, about eight hundred. The total loss sustained in these three cities, and in Mogadore, was estimated at one hundred and twenty-four thousand five hundred souls. In the regular progress of the disease, buboes make their appear- ance first, and about the second or third day from the attack; then carbuncles and ignis sacer, if either of these occur at all; and, lastly, as the danger increases, petecchiae and vibices. But, as already ob- served, where the plague shows great malignity from the first, it opens with petecchiae and vibices, and sometimes kills in a few hours even before these have time to appear. Buboes, in the opinion of all the practical writers, or nearly with- out an exception, are a critical mark of the disease, and the natural means of conducting it to a favourable termination : but in order, says Mertens, to their proving beneficial, they must undergo perfect suppuration. In many instances they neither inflame nor become 432 HJEMATICA. [CL. I1I.-0R. III. painful; and in others they suddenly disappear after having reach- ed the size of walnuts. In the former case they afford no re- lief, in the latter death is almost sure to follow speedily. The ear- lier they make their appearance the better; and upon a free sup- puration they certainly render the patient less susceptible of the disease afterwards. In the opinion of M. Sotira, indeed, and of most of the French medical staff appointed to the Egyptian expe- dition, they prove an indemnity for life: yet the examples of a se- cond attack are too numerous to allow us to adopt this opinion as a general rule. Mr. George Smith, surgeon of the Russian Imperial Land Cadet corps of nobles, was twice a sufferer from the plague at Bucharest in the year 1772, as 1 think, and had the rare privilege to recover^ from both assaults. But that an exemption for a considerable term of time is hereby very generally obtained, is established by innumera- ble examples, of which it may be sufficient to quote that of M. Ma- thias Degio, one of the surgeons attached to the same establish- ment. " Perceiving," says Dr. Guthrie, " the gentlemen of his profession condemned, in a manner, to death if punctual in their du- ty, he had the resolution to inoculate himself for the plague in a full confidence of its efficacy; and ever afterwards found himself invulnerable, while his companions around him were falling victims to its fury."* Of the efficacy of inoculation from the virus of a buboe there can be no question; and we have hence a sufficient proof of the specific character of the eruption; but it is not always a successful efficacy; and, even where it is so, as the extent of the immunity is not suffi- ciently ascertained, inoculation for the plague is by no means to be recommended. We are told by Mr. (now Sir John) Webb of a bold experimenter in the person of a young physician and hospital sur- geon attached to the British army at Rosettain 1802, who, to deter- mine the question whether the bubonous virus of the plague be or be not a specific and propagable poison, inoculated himself at El- Hamed, on January 3d, twice by friction from the matter of a bu- boe, and once, on the ensuing day, by incision. He was attacked with rigor and other symptoms of fever on the evening of the 6th of the same month, which proved to be the plague, became deliri- ous on the 8th; and continued in this state till the evening of the 9th, when he expired.t I gladly avail myself of this authentic narrative of the Director General of the Ordnance Medical Department, published since the preceding pages were written, in confirmation of the general state- ment here offered; and as containing, if a feeling of high esteem and friendship have not unduly biassed my judgment, one of the * Guthrie's Observations on the Plague, &c. in Edin.

I.] SANGUINEOUS FUNCTION. 433 most valuable documents we possess on the subject; particularly in respect to the best practical means of opposing the influence of this desolating scourge upon a large scale. Sir John Webb's narrative embraces the history and progress of the plague as it appeared in the British army employed in the conquest of Egypt in the years 1801, 1802, and 1803, during the whole of which time he was present and actively engaged in arrest- ing its course : and it justifies us in drawing the following conclu- sions. Firstly, that the disease is specifically contagious. Secondly, that the atmosphere of contagion is very limited; and that hence it is by no means difficult to avoid being infected. Thirdly, that the disease makes its attacks with very different degrees of malignity, at different seasons of the year, and on different constitutions. And fourthly, that those who reside in a place in which the plague exists, and have been gradually inured to the influence of the pesti- lential miasm, are less disposed to be affected by it than those who are fresh to its poison ; and, as in the case of the jail-fever, may carry about them, in their clothef, effluvium enough to infect those who come within its atmosphere, while they themselves remain in a state of health. The first position is sufficiently proved, not only by the lest of inoculation just adverted to, but by numberless other facts; of which one of the most forcible is the following : A lieutenant of the 10th regiment of foot, residing in Alexandria, was attacked with the disease and conveyed within the boundary of the quarantine. A rent having been made in his musquito curtain, it was taken without his knowledge by John Lee, a private, and servant to the lieutenant, who prevailed on the cenrinel to let him pass, in direct violation of orders, to another private of the same regiment of the name of William Bower, to be repaired; after which Lee imme- diately carried it home, and at his own request accompanied his master into the pest hospital, and attended him till he recovered. On the fourteenth day after this visit of Lee to Bower, the latter was taken ill with very suspicious symptoms, which, on the idea that it was an attack of plague, could be accounted for by no one till the application to repair the musquito curtain was recollected by the patient. The suspicions were confirmed on the next morning, and in the evening he died. So long, however, as the line of separation was faithfully maintained, and the sound and the diseased were thus kept distinct, there was scarcely an instance in which the disease broke out among the former. I say scarcely an instance, because an anoma- lous case or two occurred occasionally. But such was the judgment and the vigilance exerted from first to last, that the Board of Heaith were able to trace almost every instance of fever to the source from which it was derived, notwithstanding the difficulty of maintaining a rigid and permanent prohibition of all communication whatever. \nd hence it is most probable that the few exceptions to the general vol. n. 55 434 H.EMATICA. [CL. HI.-OR. III. fact proceeded from a disobedience of orders which the Board were not able to detect. In general, Sir John Webb observes that the course of the disease is nearly the same every year, and equally varies in different seasons of the year. In Egypt it commences in November, at which time it rages with its most deadly malignity, " and those who are affected by it sink into the grave almost without complaint." It continues its ravage with little abatement through the winter and the earlier part of the spring, when, as the weather becomes warmer by the approach of summer, its attacks are less frequent, its symptoms much milder, and it subsides into a manageable malady ; still, however, retaining the characteristic test of glandular affection : and on the 24th of June the Turkish government announces to the public its supposed cc^ation by a discharge of cannon. Sir John, however, with great judgment, entertains doubts of its entire cessation even then or at any lime ; and brings a proof or two of its existence during the period of official emancipation. In few words, he conceives the plagfte to exist in Egypt as the small- pox exists in England; only, from a greater regularity in the atmospheric changes of the country, evincing a greater regularity of epidemic flux and reflux, operated upon at the same time by contingencies often difficult to be developed; and hence equally varying in violence and extent. That the miasm of plague, like that of typhus, is sometimes inert upon those habituated to its influence, is obvious from the following fact. " When our Pest establishment at the camp was broken up, I discovered that the Arab servants, who had been employed in it, had secreted a great part of the clothing of the men who had died of the plague ; some of which they wore with great satisfaction and perfect impunity." I have noticed this effect of habit in the preceding view of the plague at Moga lore : and to the same cause Sir John Webb ascribes it that the Chasseurs Britan- niques, on their first arrival at Alexandria from Trieste, suffered far more severely from the disease than the troops that had been stationed there for some months. How slightly the disease makes its assault upon some constitutions, may be inferred from the case of one of the sailors of the Major transport, who was attacked towards the end of March with an inguinal buboe, but was otherwise in perfect health. " The man," says the Director General, " declared he had had it three days, and attributed it to cold. I was, however, satisfied, after a careful inquiry into his state, and an examination of his leg and thigh of the same side, that it was an effect of pestilential contagion, but in its mildest form. He was, therefore, placed in a separate tent, and a gentle aperient was administered, which was all the medicines he required. On the 2d of April I found the swelling had begun to diminish, which it continued to do until it entirely disappeared." The following description is of a different character. It is written with a touching simplicity that does credit to the author'*; GE. IV.-SP. I.] SANGUINEOUS FUNCTION. 435 heart, and will not be read without feeling by the most torpid. " As I approached the beach to examine them (the sick and sus- pected of the Major transport,) the first object that presented itself was a young woman supported in a chair (Francisca Kennis,) moaning under oppressive disease. She stared wildly about, quite insensible to every object around her, and there was a muddy glistening in her eyes, which I had seen described, but had never before observed. Her husband stood over her in the deepest distress, and held a lovely infant to her breast, who tranquilly sucked the poison that soon afterwards destroyed him. I feared at first that force would have been necessary to separate the father from his wife and child, but he at length yielded to entreaty, and, was removed from the infection, though too late to save his life. She was conveyed to the Pest Hospital, where she soon expired ; and the child was confided to an Arab, who fed and watched over it with the greatest care. On the 28th of March, the fifteenth day after the separation took place, the infant was attacked with plague, and languished until the 14th of April, when death terminated his sufferings."* Upon an average, from a table of the general return of the loss sustained by the British army from the plague, during the conquest and evacuation of Egypt, from the 8th of March 1801 to the 8th of March 1803, comprising just two years, it appears that the whole number of sick was 660:—of whom 361 died, and 299 were dis- charged cured : making the deaths rather more than half the number attacked. And further, that of the above 660, 612 were seized between March 8th, 1801, and June 30th, 1802, being nearly sixteen months ; and only 48 between July 1st, 1802, and March 8th, 1803, including the remainder of the time : a result which reflects a very high degree of credit on the means resorted to on the occasion, and on the vigilance and activity with which they were carried into execution : 361 being the entire loss sustained from this fatal scourge operating through a period of two years : whilst in the French army in the same quarter, as we learn from M. Desgenettes, not more than one in three of those that suffered were fortunate enough to recover. Such is the history of plague as it has shown itself in different ages and parts of the world, collected from the writings of unim- peachable eye-witnesses of its progress. In the midst of many discrepancies it exhibits a sufficient identity of charicter; and I have dwelt upon it the more largely, because, from the time of Dr. Cullen to the present day, its discrepancies have been chiefly attended to. And hence, while some writers of respectability have attempted to divest it of one, and others of another of its peculiar and most striking attributes, as that of contagion,! or that of atmos- * Loc. citat. p. 148. t Lange Rudimenta doctrinoe de peste.—Magirus, Von der Pest.—Maclean, Results of an Investigation respecting epidemic and pestilential diseases, includin» researches in the Levant concerning the plague. 436 H/EMATICA. [CL. I.l.-OR. 111. pheric influence,* some have been equally inclined to sweep the whole away at once, and to reduce it to a mere modification ot typhus or some other fever of great malignity.t From its history, then, let us endeavour to collect its pathology, or the laws by which it is governed, and which connect it with or separate it from other exanthems. In the first place, it is obvious that the plague, like many other febrile eruptions, is under the occasional influence of various con- comitant circumstances that give a considerable diversity to many of its features. Its proper fever is an acute typhus ; but even this, by the constitution of the individual, or the peculiar state of the atmosphere, sometimes changes to a remittent, and even an inflam- matory type. So the measles and small-pox, whose proper fever is a cauma, sometimes change, as we have already seen, into a typhus or synochus. The final end of the fever in plague, as in other exanthems, is to restore the body to health by throwing the morbid ferment to the surface in a specific way. And, as in other exanthems also, a very small degree of fever is requisite for this purpose. And hence we find that wherever the disease runs through its progress kindly, the fever is slight in degree and short in continuance ; and the specific eruption shows itself in its perfect character. In the small-pox we sometimes find scarcely any erup- tion, and very little disturbance of the system ; and the same benign disposition is occasionally found to attend the plague ; for the soldier who is struck while in the ranks with a sudden shock, or m'arop, as the Arabians call it, and is taken to the hospital on one day, has in a few instances, by proper treatment, passed through the febrile assault in three or four hours and resumed his station the day after:{ the disease in such cases evincing the same rapidity of attack and recovery as we have already noticed in that tremendous and fatal scourge, the spasmodic cholera of India, to which the plague bears a near resemblance in many respects. jS"ext, the proper eruption of plague is that of buboes ; and where these alone arise, and in their proper period, the disease is not accompanied with much danger. They are always a favourable sign, and seem to afford the longest indemnity against future attacks. When the fever is more considerable, carbuncles, the jimmerat of the Arabians, are thrown out at the same time over different parts of the body; and there is in this case always great debility, which is probably the cause of their appearance, and a considerable degree of danger. And if the fever run still higher, the danger will be proportionably increased, the proper eruption of buboes * Sir Brooke Faulkener.—Tully, Hist, of Plague in the Islands of Malta, Gozo, Corfu, &o. 8vo. 1821.

I.] SANGUINEOUS FUNCTION. 637 may perhaps be supprest, and carbuncles alone be found, highly malignant, and secreting a most acrid and corrosive ichor which burns as it oozes and spreads about, and occasionally forms extensive trails of painful and distressing sores. But the fever is often still more acute, and especially, for a rea- son we shall presently notice, when the disease earliest appears among a people ; and the danger may be imminent from the first shock. The typhous symptom* are here of the most malignant nature; there is a sudden and almost utter exhaustion of sensorial power without the smallest means of recruit: all the larger viscera are disturbed in their functions, the head, the heart, the lungs, the stomach, and the liver; some overwhelmed with congestion, others sinking and powerless, as though the morbid virus were translated from the surface to themselves; the only active principle through- out the entire system being that of fever itself; which increases with the increase of the general mischief, and, like a house on fire, gathers fuel from the downfall of the fabric. All the symptoms of putrefaction make an early appearance, and appear at the same time under these circumstances; the animal spirits fail and are de- spondent ; the respiration is anxious and feeble; the stomach faint and sinking, or the brain comatose; purple stigmata and vibices are scattered over the body; and the patient is destroyed by the incur- sion of the eruptive fever, as often happens in the small-pox, before the specific tokens have time to show themselves. Of the primary source of plague we are in as much uncertainty as in respect to that of any other exanthem; it appears, however. to have a just claim to a higher antiquity than any of them; for we have already seen that it was known in an early era to the Greeks, and that histories of it, as it has shown itself in different ages and countries, have descended in a regular stream of Greek, Arabic, Roman, and neoteric writers down to our own day. That, like other exanthems, it consists in and is propagable by a specific virus is unquestionable ; for we have also seen that it has often been put to the test of inoculation ; and, like most other exanthems also, it appears to be dependent for an extensive spread upon the same ac- cessories as give rise to febrile miasm or contagion ; and which, as already noticed, are for the most part the common auxiliaries of putrefaction.* Whether any combination of these be capable of originating it of themselves either without or within the human body, or whether it be only propagable by a stream of hereditary descent from primary matter communicated from place to place, is a pro- blem to the present hour; though it is probable that the law which in this respect governs most of the other exanthems as measles, small-pox, and scarlet-fever, governs the miasm of plague also: for all of them, while derivable by communication with the affected, seem, at times, to have assumed the form of epidemics. In deducing the more obvious laws that regulate febrile miasm, * See Vol. n. p. 52. 438 H^MATICA. [CL. lll.-OR. HI. I observed at some length that whenever originating from the hu- man body itself, this miasm does not seem to be very volatile and is soon dissolved or decomposed in an atmosphere of pure air :* and we have since had occasion to apply the same remark to the speci- fic miasms of all the preceding exanthems. I have now to observe that it applies especially to that of plague, whose sphere of infec- tion in pure air appears to be more limited than that of any of the rest; on which account, indeed, it has been held by many who have practised in the field of this disease to be communicable by contact alone. Such, in truth, seems to be the surest way of communica- tion, and may in all common cases be regarded as a way altogether irresistible : but it is not the only way. In the pure and healthy air of Malta, during the irritation of the plague in 1813, it was almost the only mode of transmission, and hence the readiness with which it was subdued by the rigid line of quarantine, which was so wisely proposed by the medical officers, and enforced by Sir Thomas Mail- land. But several of the most intelligent residents on the spot, and even Mr. Tully himself, who in his work on this subject has held up contagion as the sole mean of propagation, have admitted to me in conversation that the disease might be received by the breath of the infected without contact, upon a very close intercourse. Sir B. Faulkner's opinion upon this point is in perfect union with Mr. Tul- ly's : " It is communicated," says he, " only by contact or close as- sociation with the person or thing infected."t And in consequence they admit that the air, even in its purest state, may become a vehicle of communication, though to a very short distance, and pro- bably for a very short period of time after being impregnated: since, as already observed, the miasm of plague dissolves in pure air with great rapidity. When, however, the atmosphere is stagnant or already loaded with foul effluvia of any other kind, especially such as proceed from the filth of close or crowded rooms, or the putrescent decomposi- tion of animal or vegetable substances, as no modification of febrile miasm, we have had reason to state antecedently, dissolves readily: and consequently the seeds of such disease may continue floating for a considerable period of time, and be driven by currents to some distance in full possession of their specific mischief; and hence, even a sporadic fever may be converted into an epidemic. It is in this way that plague appears in many cases to have ex- tended itself; for it would be unjust to the character and good sense of a cloud of intelligent witnesses to deny that this disease some- times also assumes the form of an epidemy. But I believe it will be found an universal fact, that it has never exhibited itself in this form except when aided by the above auxiliaries. Thus much is certain, that it has always raged with most violence and to the greatest extent in cities and districts where the atmosphere has * Vol. ii. p. 52. t Minutes of Evidence before the Select Committee of the House of Commons. •;e. iv.-sp. l] SANGUINEOUS FUNCTION. 439 been least pure, the human frame most debilitated, and the tenden- cies to putrefaction strongest and most multiplied, as in times of famine or any other general distress, and in the close and squalid quarters of the poor of every city into which it has found an en- trance, if it have not even originated there. This fact, indeed, is so common, that while many writers have contended that plague can onlj be propagated by actual contact, others, of equal authority, have maintained that the disease is alto- gether an epidemic, as directly dependent upon the state and con- stitution of the air as any epidemic whatever; and that to attempt to cure it by a mere interdict of communication between individual and individual is equally weak and wicked. The view now taken of the disease is calculated to reconcile these conflicting opinions, and to bring into a state of amity the most sturdy adversaries in the contest. In enforcing the line of quarantine at Malta,* Sir Brooke Faulkner most wisely took especial care to enforce at the same time a rigid attention to purification of every kind, and I shrewdly suspect that, without the latter, his cordon would have been but of little avail. Thus far the ordinary course of plague does not essentially vary from that of most of the exanthems we have already considered. The general laws of any one are those of the whole : they are all deflected, and exhibit some variety of features by particular cir- cumstances ; but each, to an attentive eye, gives sufficient proofs of identity in the midst of every modification, and is specifically dis- tinguished from the rest. There are two or three properties, however, which, if not pecu- liar to the plague, are indented upon it far more strikingly than upon any other disease of the same order, or perhaps of any order what- ever : and we will next proceed to a brief examination of them. The ordinary mode of. infection on exposure to an exanthema- tous patient is, by inhalation or deglutition ; probably by the former; for variolous contagion has been swallowed in the way of experi- ment without producing any influence. How far any other virus besides that of the plague is receivable by the pores of a sound skin is to this hour a matter of doubt. In the case of plague, however, there ought not to exist the shadow of a doubt; for, though the miasm is probably communicable within the sphere of its activity, by the mouth or nostrils, direct contract or absorption by the skin forms the ordinary means of its conveyance. Upon this point, al- most all the writers of authority, who have been professionally en- gaged in opposing its progress, are concurrent. And hence, again, whatever obstructs or corrugates the mouths of the cutaneous ab- sorbents becomes a certain anti-loimic. Oil seems to do this most effectually; it was accounted " the sovereignst thing on earth" in the last pestilent ravage at Malta ; and Mr. Tully has informed me that there was no instance of an attendant on the infected having * Treatise onthe Plague, by Sir Arthur Brooke Faulkner, M.D. 8vo. 1820. 440 HjEmatica. [cl. ih.-or. hi. received the contagion so long as he was regular in thoroughly il- lining himself with oil, wearing a dress soaked in oil, or a covering of oil-skins. And to the same effect is the evidence of Sir Brooke Faulkner, physician to the forces at Vlalta in 1813, before the Se- lect Committee of the House of Commons, June 14, 1819, who, in answer to the question " How were the military attendants pre- served ?" replied. " with respect to the Pest hospital in which ' at- tended, they were, in my opinion, preserved by wearing a dress of oiled silk, which prevented the possibility of any contact of infected matter with the skin, and probably, also, b\ its promoting free and copious perspiration, and, in consequence, preventing absorption.*'* To the same effect it has been asserted by Mr. Baldwin of Cairo, that among upwards of a million of inhabitants carried off by the plague in Upper and Lower Lgvpt during the space of four years, not a single dealer in oil, so far as he could learn, had fallen a sa- crifice to it."t A simdar remark is made by Mr. Jackson respect- ing the crolies or labourers in oil-warehouses during the Barbary plague just referred so. In that of London in 1665, it is specially observed by Baynard, and most of the writers, that the trades chiefly exempted were tbose of oilmen, fishmongers, tanners, bargemen, and watermen: the first three evidently protected by the greasy viscidity that covered the hands and dress generally; and the last two by living separate from the scene of contamination, as though cut off by a quarantine. While, on the contrary, it has been quite as generally remarked that the descriptions of persons most expos- ed to infection are bakers, cooks, and smiths, the pores of whose skin are kept in a state of perpetual irritation and relaxation from their respective employments. How far an habitual exposure to the miasms of other exanthems torpefies the skin to their action, or whatever other organ affords them an inlet; or how far the system at large may be thus torpefied, has not been determined with any degree of satisfaction. That stimulants of most kinds have a tendency to produce such torpitude and inirritability is unquestionable; and that the miasm of gaol-fever has occasionally done it, will not soon be forgotten in the courts of judicature of our own country. It is hence probable that the efflu- vium of exanthems, in general, is possessed of a like power. But in the case of plague the fact seems to be unequivocally and most strikingly established ; for we find in every country, after it has raged for a certain number of weeks or months, that the disease is both caught more sparingly, and exercises far less violence, at least upon those that have been exposed to its aura; for upon new comers or strangers it still retains its virulence. The history of almost every plague may be taken in confirmation of this remark; but it is particularly established by numerous facts already quoted from Sir * Copy of \linutes, &c. As also Sir A. B. Faulkner's Treatise on the Plague, Sic. Appendix, p. 16, 8vo. 1820. + Travels, &c. Chap. xvn. GE. IV.-SP. I.] SANGUINEOUS FUNCTION. 441 John Webb and Mr. Jackson. It is highly probable, that if the corps of troops which, after the mortality had subsided at Moga- dore, arrived there from the city of Terodant in the province of Suse, where the plague had been raging and had subsided, had remain- ed at Terodant, it would have continued to escape. But it lost its immunity by an exchange of contaminated for pure air in the course of its journey, and the organs, having acquired their wonted irrita- bility and susceptibility, were as open to infection as those of fresh persons. The acquisition, then, of a growing torpitude to the action of the pestilential effluvium beneath an habit of exposure to its influence, seems unquestionable ; and puts us in possession of one mean of the progressive subsidence of this tremendous scourge, after having oc- cupied a town or district for a certain period of time. But there is an additional cause of its cessation, which is equally striking, and forms another of the peculiar features of this com- plaint. As a particular state of the atmosphere, such, for instance, as its being saturated with foreign corpuscles from decomposing ani- mal filth, renders it a bad solvent of pestilential miasm, and conse- quently a ready vehicle for the spread of the disease, a particular state of the atmosphere of some other kind seems to possess a pow- er of dissolving the effluvium instantaneously, in many cases, and of diluting its virulence in others. Of the immediate nature of this at- mospheric change we are in a very considerable degree of igno- rance, but of the general fact there is not a quarter of the world that does not furnish us with examples : so that all of a sudden the scourge that has hitherto been sweeping off one or two thousand inhabitants of a city every day either totally vanishes, or drops its mortality, and only continues in a form so mild as to excite no alarm. Dr. Hodges notices this sudden change very particularly in the plague of London. " In the beginning*!' November," says he, " people grew more healthy, and many came into the city without fear ; so that in December they crowded back as thick as they fled : and such confidence was now inspired that many went into the beds, v/here persons had died, before they were cold, or cleansed from the stench of the diseased ;for the nature of the disorder was chang- ed.* " Even the physicians themselves," says another eye-witness of the same pestilence, "were surprized: wherever they visited they found their patients better. Either they had sweated kindly, or the tumours were broken, or the carbuncles went down, and the inflammation round them changed colour, or the fever was gone, or the violent head-ache assuaged, or some good symptom was in the case : so that in a few days whole families that expected death every hour were revived and healed, and none died at all out of them."t * Loimol. p. 27. t Journal by H. F. p. 250. vol.. II. 56 442 HJEMATICA. [CL. III.-OR. Mr- Alpinus speaks in the same manner of the sudden decline of mor- tality in the plague of Egypt: "In the month of June," says he, " to whatever degree pestilence may be raging in Egypt, as soon as the sun enters Cancer it ceases entirely." And Dr. Russell confirms this remark as follows :—" It is agreed on all hands that about the 24th of June, at Cairo, there is a remarkable sudden alteration id the contagious property of the plague, as well as in the malignity of the disease itself, to whatever cause it is to be ascribed; and Alpi- nus's remark, that at the same time it ceases, the furniture in infect- ed houses suddenly loses all power of communicating the disease to the inhabitants, so that health and tranquillity are at once restored, agrees in some measure with the general experience of other places in Turkey, where it is well known houses or goods undergo little or no purification."* Mr. Bruce speaks to the same effect: " The Turks and Moors, immediately after this day, expose in the market- places the clothes of the many thousands that have died of the plague during its late continuance; and though these consist of fur, cotton, silk, and woollen-cloths, which are stuffs the most retentive of the infection, no accident happens to those who wear them, from their happy confidence." And we are hence able to enter more fully into the meaning of a passage already quoted from Sir John Webb, in which he tells us that on the approach of summer the plague sub- sides into a manageable malady, and that on the 24th of June the Turkish government announces to the public its supposed cessation by a discharge of cannon. Unless, therefore, we withhold, most unjustly, all belief in this accumulation of unimpeachable evidence, it seems impossible not to admit that the state of the atmosphere is connected with the decline of the plague, and consequently with its previous progress : while its dependence upon a specific miasm seems equally clear from its occasionally commencing in the healthiest, as well as in unhealthy seasons ; though most frequently, and most fatally, in the latter. In the plague of London, as we have already seen, the disease followed upon a malignant epidemy; in that of Athens, the preceding year had been so peculiarly healthy that mankind seemed to have ac- quired an exemption from complaints of every kind. In that of Egypt, it makes a regular return whatever be the constitution of the season. In entering upon the medical treatment of plague, I regret that I am not able to give the judicious plan, in conjunction with its re- sults, that was adopted for the British army in Egypt. The care of the Pest Hospitals did not fall within the range of Sir John Webb's department, but I availed myself of his friendship to solicit in- formation upon this subject from his colleague Dr. Buchan, who, 1 have reason to believe, had made a journal of very valuable notes in relation to it. The public will hear, with regret, that this infor- mation is incommunicable from the destruction of a great part of * On the Plague, B. in. Ch. v. OE. IV.-SP. I.] SANGUINEOUS FUNCTION. 443 these minutes, which followed the fate of Dr. Buchan's clothes and bedding at the time of his quitting the hospitals. Respecting the proper plan to be pursued, there is still some controversy. Early, copious, and even repeated venesection was at one time, and by very high authorities, recommended in this dis- ease, and especially by Sydenham at the commencement of the plague of London in 1665 and 1666, before the appearance of any eruption. Like Dr. Rush, in North America, respecting the yel- low fever, he was stimulated by the bold determination of quelling this formidable enemy in its very onset, and before it should have made a fatal breach in the constitution. This practice, however, has been far less successful, and therefore less persevered in, with regard to the plague, than with regard to the yellow remittent. Dr. Mergens says, he would never advise its being resorted to: and even Sydenham hesitated as he became more experienced. " But though," says he, "I approve and have'often experienced the uti- lity of bleeding, yet for several reasons I prefer the dissipation of the pestilential ferment by sweat, because sweating does not in the same degree prostrate the patient's strength."* Where there is great and threatening congestion in a large or vital organ, bleeding, and bleeding freely, should certainly be employed, for this symptom alone would lead to a fatal issue. But the practice must form an exception to the general rule, and not the rule itself. The use of external cold by the application of sheets of pounded ice to the body generally, has been also tried, but with no satisfac- tory result. It has, indeed, been chiefly confined to Russia, under the vigilant eye of M. Samoilowitz. How far it might succeed in warmer climates is uncertain, but ablution with cold water offers a fairer promise. A brisk emetic, given at the commencement of the attack, has often proved of the utmost advantage. M. Degio, to whom I have already adverted, affirms that he has seen men, sud- denly cut down by the disease when on duty, as though shot by a musket-ball, so completely recovered by an emetic given instantly, as to be on duty again within twenty-four hours afterwards.1 If the nausea and bitter taste in the mouth be not removed by a first eme- tic, a second, and even a third is often prescribed; and, when the symptoms are urgent, at a distance of not more than four or five hours from each other. And this plan is found to produce far less exhaustion than that of purging which the patient is often unable to support. After evacuating the stomach, and hereby exciting a determina- tion towards the skin, the cutaneous action is to be maintained by aciive and cordial sudorifics, which, indeed, constitute the ordinary plan of the present day. For cordials, there is the utmost necessity : the debility is, from the first, extreme and threatening,and the vascular "' Loco citato. t Substance of notes taken at the Russian army during the prevalence of the Plague. Sec Edin. .Med.jCom. Vol. vm. p. 352. 444 ll.EMATICA, [CL. IH.-OR. III. action must be supported at all adventures. Even Sydenham, who at one time hesitated as to the use of them upon theory, in which he did not often indulge, was obliged to admit their beneficial ef- fects, though he regarded the practice as hazardous. With respect to sudorifics, the concurrent voice of all physicians in all countries is in their favour. Diaphoresis is, indeed, the evacuation that re- lieves most certainly and most effectually; and it should be main- tained by warm, diluent and supporting drinks. James's powder employed without cordials does not appear advisable. It was very largely administered at Moscow, but, according to Dr. Mergens, with no particular advantage. In many cases, the warmer opiates as the opiate confection, have been found serviceable, assisted with cam- phor and ammonia, and blisters repeated in succession. As oils of all kinds applied to the surface of the body have been found a good preservative against the absorption of the contagious miasm, it has been also had recourse to, and employed in the same manner as an antidote when the disease is present, and particularly in the east where the zeit jagghy, or olive oil, has been regarded almost as a specific. Mr. Baldwin affirms that he made use of it in this form very extensively at Cairo, and with great success: and it is usually employed in Barbary and at Constantinople. The French physicians, however, do not seem to have relied much upon its vir- tue. M. Sotira suggests that Mr. Baldwin's benevolence in the dis- tribution of oil for this purpose was occasionally abused, and the cures by oil exaggerated and multiplied by those who wished to have oil gratis. M. Assilini, however, inclines to a belief that it may be useful; and it is most pointedly recommended by father Louis of Padua, director of the hospitals at Smyrna. The application should be accompanied with a long-continued friction; and, when successful, is followed in about half an hour by a perspiration pro- fuse and general, and which affords immediate relief. It is not difficult to reason upon the subject: the oil probably obstructs the pores of the skin, and prevents the escape of caloric, which, aided by the friction, accumulates on the surface, and shortens, or alto- gether prevents, the shivering fits, which are otherwise very se- vere. Sir Brooke Faulkner admits its sudorific power, but is by no means friendly to its use ; believing that even by this very power it has often proved highly injurious. Yet he does not speak from much personal acquaintance with its effects; but tells us that u a gentleman who superintended the health of one of the districts of Valetta, assured him that although he had constant opportunities of seeing oil frictions used by those under his immediate orders, he was satisfied that it was not merely useless as a defence, but hurtful to the general health, by the debility which succeeded to the pro- fuse perspirations which it occasioned." Sir Brooke, in the passage of his work now referred to, estimates its prophylactic virtue as low as its remedial,* and is thus far in a state of direct antagonism, not * Treatise on the Plague, &c. pp. 231, 232 GE. 1V.-SP.

In the remissions of the fever, the bark is used in great abun- dance, commonly intermixed with port or other generous wines. During the fatal plague which depopulated the whole of western Barbary in 1799, the Emperor Sidi Soliman is said to have had the disease twice, and in both cases to have derived his cure from a free use of the bark : in consequence of which, he was never after- wards without a large supply of it. When buboes or carbuncles appear, they are always to be promoted and matured by warm cata- plasms. Camphor, smoking tobacco, fumigation with gum sandrac, and the vinegar of the Four Thieves, are still largely employed as pre- ventives. But the contagion, as we have already observed, is not peculiarly active, and the best prophylactics are cleanliness, pure air, freedom from actual contact, a liberal diet, and cheerful spirits. I may add that vaccination has been repeatedly tried ; but has answered no good purpose. Sir Brooke Faulkner, indeed, gives a striking example of its failure, for " in a numerous family,'' says he, " who had been recently vaccinated, the whole fell sacrifices to the prevailing contagion, with the exception of the parents who had never undergone the operation."* SPECIES II.

The term rubula, by which this disease is distinguished in the pre- sent work, is derived from the Latin rubns, " a black-berry or rasp- berry," in French framboise, whence the common but barbarous name of frambcesia, quite as objectionable as that of scarlatina; and which the author has thus attempted to exchange for an euphonous and strictly classical term, in perfect accordance with the ordinary law of diminutives, which seems to prevail through the general no- menclature of exanthematous diseases, as rubeola, variola, varicella. Treatise on the Plague, p. 233, 446 HjEMATICA. [CL. HI.-OR. III. Perhaps morula, from morus, a mulberry, a diminutive used in an approximating sense by Plautus, might have been somewhat more appropriate, since the eruption seems to bear a nearer resemblance to small mulberries than to rasp-berries. But as this last plant has laid a foundation for the vernacular name both on the African and American coast, on the former of which it is called yaw and on the latter pian or epian, both importing rasp-berry ; and as the earliest writers have, upon this authority, denominated it framboise or fram- bcesia, I have not felt myself at liberty to deviate, from the original idea. The disease as it occurs in Africa and America, exhibits some di- versity, and lays a foundation for two varieties as follow: x Guineensis. Attacking infants and young per- African Yaws. sons chiefly; and subsiding ac soon as the eruption appears. & Americana. Depascent; and destroying pro- American Yaws. gressively both muscles and bones. In the precursory remarks to the present genus, I have stated the reasons for introducing this species into the list of exanthems, or febrile eruptions; and the history of the disease will still further show that it could not with propriety have been placed under any other division. It is singular that we have no decided account of this malady among'the early writers; nor, indeed, any account whatever till after the appearance of syphilis ; whence, as several of its symptoms, and especially when the bones become affected, bear a resemblance to those of syphilis, yaws have been supposed by some writers to be a species of lues, and especially of that which in Scotland is denominated sibbens or sivens, of which we shall treat in the ensuing order: but the eruptive fever and consequent efflo- rescence, the indemnity from a second attack, as well as other symp- toms, draw a sufficient line of distinction. The first variety will often run through its course favourably without any medical assistance whatever; and is, indeed, often in- jured by it when incautiously and injudiciously interposed. This seems to be the primitive form, and thatu nder which it chiefly shows itself in Guinea, and some other parts of Africa, where, as just ob- served, it is vernacularly called yaw or morbus rubulus. It commences, like the other exanthems, with the ordinary symp- toms of fever, although they are usually more tardy in their pro- gress. Hence the precursory symptoms are languor, debility, head- ache, loss of appetite, rigor, and pain in the back and loins, which continue for a few days with evening exacerbations. To these suc- ceeds the specific eruption; consisting of successive crops of pa- pulae, at first not larger than a pin's head, but increasing in size with every series till they acquire the magnitude of a rasp-berry or mul- berry. The smaller papula? become real pustules, and discharge an GE. IV.-SP. II.] SANGUINEOUS FUNCTION. 447 opake whitish fluid when broken, and concrete into dense scabs or crusts. The larger are fungous excrescences, and, in their granu- lar surface, as well as in their size and colour, bear a near resem- blance to the fruit from which they derive their name. These sprouting tumours have but little sensibility, and suppurate very im- perfectly ; discharging rather a sordid ichor than a matured pus. They originate in scattered groups over different parts of the body, but are chiefly found, like the eruption of plague, in the groins, parotid glands, axilla?, and about the arms and pudenda: though they often disfigure the neck and face. The colouring matter of the hair, wherever they are seated, is obstructed in its secretion, and, as in ojd age, the hairs themselves, from a brown or a black, be- come a dead white. Dr. Thomas, who has given a very accurate account of this variety, apparently from personal knowledge, ob- serves that, " in general the number and size of the pustules are proportioned to the degree of eruptive fever. When the febrile symptoms are slight, there are few pustules; but they are mostly of a larger size than when the complaint is more violent and exten- sive."* The duration of the eruption is uncertain, and seems to depend considerably upon the state of the habit, and its power of promoting their maturity. They sometimes acquire full perfection in four or five weeks, and sometimes demand two or three months. In their progress to this state, there is usually some one that appears larger and more prominent than the rest, and is called the master-yaw. It is, in truth, a broader and more sloughy fungus, and discharges a larger portion of erosive sanies, which if not washed off as it issues, will spread widely, and sometimes work its way to an adjoining bone, and render it carious. When the tumours point from the soles of the feet, they cannot press through the thickness of the skin, and hence acquire form imperfectly, and produce highly elevated callu- ses, which are called tubba or crab-yaws : and often very much im- pede the power of walking. As soon as the eruption has attained its height, the tumours, when the disease proceeds favourably, be- come covered with crusts or scabs, which fall off daily in whitish scales; and, in the course of a fortnight, the skin is left smooth and clean; the master-yaw alone remaining and demanding attention. In attempting the cure of this disease, the first step should consist in separating the pati^^from his associates, to whom he will otherwise assuredly conjHpcate it by contagion. He should then take freely of decoction of sarsaparilla or some other warm di- luent, for the purpose of attenuating the specific virus in the blood, and quickening its passage towards the surface. And it is highly probable that the warm aperient bolus, composed chiefly of a scru- ple of sublimed sulphur and five grains of calomel, as recommended by the anonymous writer of a very excellent treatise upon the sub- Pract. of Phys. p. 643. cd. 1819. 448 I-LEMATICA. [CL. HI.-OR. III. ject in the Edinburgh Medical Essays,* may be found serviceable, continued every night. The master-yaw must be attacked with es- carotics, for it is to be destroyed in no other way. The callous tu- mours on the soles of the feet, should be softened by warm water, or cataplasms of some gentle stimulant; and, when on the point of breaking, are best attacked with a slight application of the actual cautery, which proves the most adviseable escarotic. The diet should be nutritious and liberal, so as to support the strength during the progress of the disease. And under this mode of treatment it is rarely that a patient fails to do well. Mercury was at one time given in great abundance from the com- mencement of the complaint, under an idea that it wouid prove as beneficial as in the case of lues. But it is now sufficiently known to be productive of great mischief, and particularly when carried, as it used to be, to a state of salivation. It retards the'cure, and generally aggravates the symptoms. It is often given in small doses as an alterative, when the disease is on the decline, and per- haps with advantage ; but it ought never to be employed in any other form. When the excrescences discharge a sordid ichor, they may also be stimulated with the nitric-oxyde mercurial ointment: but the na- tives themselves, who rigidly abstain from the internal use of mer- cury, employ, instead of this, a liniment of the rust or sub-carbon- ate of iron and lemon-juice, which proves a very useful application; though probably a solution of sulphate of zinc might answer better. And during the maturation of the eruption they excite a profuse sweat by what may be called a warm air bath, which consists in putting the patient into a cask with a fire at the bottom in a brazier or small fire-pan ; the top being covered over with a blanket. Un- der this mode of treatment a cure is said to be often effected in three weeks, and the funguses thoroughly healed.t ^ The second, or American variety, is a far more terrible com- plaint ; or rather is the same complaint in an exasperated and chro- nic form; and hence, though incomparably slower in its progres- than the plague, is accompanied with a carbuncular eruption quite as mischievous and disgusting, and more certainly fatal in its issue. It was first distinctly described by M. Virgile of Montpellier, who had practised with great reputation at St Domingo. There can be lit- tle doubt of its being imported intdHfet West Indies along with the slaves from the African coast; artd^ls here calied, as already ob- served, pian or epian, precisely synonymous with the African term yaw : the master-fungus being named mama-pian, or mother-yaw, as supposed to be the source or supply of the rest. The fungous ber- ries in this form, precisely correspond to the carbuncle already de- scribed under the trivial name of terminthus, which consists of a " core of fungus spreading in the shape, and assuming the figure. * Vol. v.

II.] SANGUINEOUS FUNCTION. 449 and blackish-green colour of the fruit or berry of the pine-nut, or terminthus of the Greeks."* And it has hence been conjectured, but without sufficient foundation, that the disease of yaws is refer- red to by Galen and Dioscorides under this name. The erosive secretion from the carbuncles of this variety, gene- rally, but especially from the mother-yaw, spreads widely, and, in its meandering, destroys all the surrounding parts, not excepting the bones. Nothing can exceed the revolting scene of a yaw-house, or hospital for the reception of slaves suffering under this disease in the West Indies. "■ Here," says Dr. Pinckard, " I saw some of the most striking pictures of human misery that ever met my eyes. Not to commiserate their sufferings is impossible, but their offen- sive and wretched appearance creates a sense of horror on behold- ing them. Of all the unsightly diseases which the human body is heir to, this is perhaps the worst. Some of these diseased and truly pitiable objects were crouching upon their haunches round a smoky fire ; some stood trembling on their ulcerated limbs ; others, sup- porting themselves by a large stick, were dragging their wretched bodies from place to place ; while many too feeble to rise, lay shivering with pain and torture upon the bare boards of a wooden platform"! Dr. Pinckard adds, that " unhappily this most odious distemper has not hitherto been found within the power of medi- cine : that it often exists for years, and even where it sooner yields, its removal is more the effect of time and regimen, than of medical treatment." This view of the case is too generally true: but from the length of time which, under the best treatment, is required to effect a cure, it seldom happens that these miserable wretches receive all the attention which their situation deserves ; and they are rarely suffi- ciently heedful of personal cleanliness, which, even alone, is of the utmost importance. This, with a generous diet to support the strength, pure air, regular hours of rest, and such exercise as can be used without fatigue, with warm balsamic applications to the sores, have not unfrequently succeeded, where the bones have not become extensively carious. But the latter stages of the disease are horrible when it proves fatal: for the pains are excruciating, the debility extreme, and the bones are covered over with a quag- mire of foul exostoses and corrupt ulcerations. It is happy for the European inhabitants of the West Indies that they are less liable to this miserable malady than their slaves: pro- bably from using a better diet and being more attentive to cleanli- ness. * Cl. in.

The words ordinarily used to import the diseases meant to be comprehended under the present order are cachexia and impetigo, or, as the Greeks expressed it, Av„s, lues, or lyes. None of these, however, exactly answer; and that, on two accounts ; first, because the order is limited to those depravities which seem to originate or manifest themselves chiefly in vessels or fluids of the sanguineous function ; and, secondly, because no very definite sense has hitherto been assigned to either of these terms ; and they- have, in conse- quence, been used in very different meanings by different writers, from the time of Celsus to our own day. Upon this subject the author has dwelt at large in his volume of JNosology, and it is not necessary to add to the remarks there offer- ed. 1 he word dysthetica has hence been adopted for the purpose of avoiding contusion, and is justified by the eusthesia and eusthetica (ET20E2IA and EYS0ETIKA) of Hippocrates and Galen, importing a "well-conditioned habit of body," as their opposite dysthetica, from the same root, imports "an ill-conditioned habit," but a habit as just observed, originating in, or dependent upon the organized parts or fluids of the sanguineous function. Thus explained: it will be found to embrace the following genera : 1. PLETHORA. PLETHORA. 2. H^EMORRHAGIA. HEMORRHAGE. 3. MARASMUS. EMACIATION. 4. STRUMA. SCROPHULA. KINg's EVIJ O. CARCINUS.

COMPLEXION FLORID ; VEINS DISTENDED ; UNDUE SENSE OF HEAT AND FULNESS J OPPRESSION OF THE HEAD, CHEST OR OTHER INTERNAL OR- GANS. Plethora is seldom ranked as a disease, and hence seldom treated of in a course of medical instruction. From what cause this omission pro- ceeds I know not, nor is it worth while to inquire. That it is an important omission will be obvious to every student before he has been six months in practice ; for there will probably be few affec- tions on which he will be sooner or more frequently ccfnsulted. Yet the subject has not always been neglected by nosologists, for plethora, as a genus, occurs in the classifications both of Linneus and Sagar. In a state of health, the quantity of blood produced from the sub- stances that constitute our common diet bears an exact proportion to the quantity demanded by the vascular system in its ordinary diameter, and the various secretions which are perpetually taking place in every part of the body. But the quantity of blood produced within a given period of time may vary; and the diameter of the blood vessels, or the call of the different secernent organs may vary; yet, so long as a due balance is maintained, and the proportion of new-formed blood is answerable to the demand, the general health continues per- fect or is little interfered with. Thus, a man exhausted and worn down by shipwreck, or by having lost his way in a desert, or who is just re- covering from a fever, will devour double the food, and elaborate double the quantity of blood, in the course of four and twenty hours, to what he would have done in the ordinary wear of life ; but the whole system demands this double exertion; the double supply is made use of, and the general harmony of the frame is as accurately maintained, as at any former period; there is no accumulation or plethora. It should also be observed, that in this case the same remedial or 4.V2 HJEMATICA. [CU- IH.-OR- IV- instinctive power that stimulates the sanguific organs to the forma- tion of a larger proportion of blood, stimulates also the blood-ves- sels to a diminution of their ordinary capacity; and lessens the acti- vity of the secernents; and hence the difficulty to which the animal machine is reduced is also met another way ; and a balance be- tween the contained fluid, and the containing tubes, is often pre- served as completely during the utmost degree of exhaustion, as in the fullest flow of healthy plenitude. We sometimes, however, meet with cases in which an increased supply of blood is fabricated when'no such increase is wanted, and the vessels remain of their ordinary capacity. And we also, some- times, meet with cases in which, from a peculiar diathesis, the capacity of the vessels is unduly contracted, while no change takes place in the ordinary supply of blood. It is evident that in both these contingencies there must be an equal disturbance of the bal- ance between the substance contained and the substance containing, and that the measure of the former must be too large for the mea- sure of the latter. In other words, there must be in both cases an excess of fluid or a plethora, though from very different, and what are usually regarded as opposite causes; and, hence, it has been distin- guished by different names; that proceeding from an actual surplus of blood being denominated a plethora ad molem, or a plethora in respect to its general mass, or absolute quantity ; and that proceeding from a diminished capacity of the vessels being denominated a plethora ad spatium, or a plethora in respect to the space to be occupied. It is possible, however, for both these causes of plethora to exist at the same time, and for the vessels to evince a contractile habit or diathesis, while the blood is produced in an inordinate proportion. And this, in truth, is by no means an uncommon state of the animal frame ; for where the excess of blood is the result of a highly vigo- rous action or entony of the organs of sanguification, we often see proof of the same entony or highly vigorous action through the whole range of the vascular system, and indeed of every other part of the machine; the pulse is full, strong, and rebounding; the mus- cular fibres firm and energetic, the complexion florid, the whole figure strongly marked. We have here the sanguine temperament; and this kind of plethora has hence been called the Sanguine Ple- thora. But we often meet with an inordinate formation of blood in a con- stitution where the vascular action is peculiary weak, instead of being peculiarly vigorous, the muscular, fibres are relaxed instead of being firm, and the coats of the vessels readily give way, and become enlarged instead of being diminished in their diameter; and where instead of entony or excess of strength, there is considerable irrita- bility or deficiency of strength in the organs of sanguification. Yet, though the cause is different, the result is the same ; the ves- sels, notwithstanding their facility of dilatation, at length become distended, and a plethora is produced which has been denominated GE. I.-sl\ I.] SANGUINEOUS FUNCTION. 453 a plethora ad vires; or a plethora as it respects the actual strength of the system. The pulse is here indeed full, but frequent and fee- ble ; the vital actions are languid; the skin smooth and soft; the figure plump, but inexpressive ; all which are symptoms of debility of the living power, or rather of that peculiar diathesis which has been distinguished by the name of the serous, phlegmatic, or pitui- tary temperament; and hence this sort of plethora has been com- monly denominated Serous Plethora. We have, hence, a foundation for the two following very distinct species of this affection the names for which are derived from their proximate causes. 1. PLETHORA ENTONIOA. SANGUINE PLETHORA. 2. ----.----ATONICA. SEROUS PLETHORA. SPECIES I. PLETHORA ENTONICA. Sanguine plethora. PULSE FULL, STRONG, REBOUNDING: MUSCULAR FIBRES FIRM AND VIGO- ROUS. Sanguine plethora is more common to men, serous to women. It is the disease of manhood, of the robust and athletic. Plethora of this kind must be distinguished from obesity ; in effect, they are rarely found in conjunction, for the entony or excess of vigorous action is common to every part of the animal frame, and hence, though it is probable that a larger portion of animal oil is secreted than in many other conditions of the body, yet it is carried off by the activity of the absorbness, and there is no leisure for its accumulation in the cellular membrane. And hence persons labouring under sanguine plethora are rather muscular than fat, and their distended veins lie superficially and appear to peep through the skin. In this state of the blood-vessels, slight excitements produce con- gestion in the larger vessels or organs. The head feels heavy and comatose; the sleep is disturbed by tumultuous dreams; the lungs labour in respiration, and the muscles feel a want of freedom or elasticity in exercise. If fever arise, it will assume the inflammato- ry type ; and a slight excess in feasting or conviviality will endan- ger an apoplexy. The cure, however, is not in general accompanied with much difficulty; and far more easily effected in this species than in the ensuing: for the entonic power may readily be lowered by vene- section and purgatives: and its disposition to return may commonly 454 HZEMATICA. [CL. I1I.-OR. IV. be prevented by the use of refrigerants, as nitre, or other neutral salts, and an adherence to a reducent diet and liberal exercise ; at the same time it should be observed, that where the plethora de- pends upon a sanguineous temperament, or phlogistic diathesis, venesection, though rightly employed at first, should be repeated with great caution, as it will tend to generate in the system a peri- odical necessity for the same kind of depletion, and consequently. promote the disease it is designed to cure. SPECIES 11. PLETHORA ATONICA. Serous plethora. PULSE FULL, FREQUENT, FEEBLE : V1T4L ACTIONS LANGUID ; SKIN SMOOTH AND SOFT ; FIGUkE PLUMP, BUT INEXPRESSIVE. The general pathology we have already treated of: and the reasons given under the last species for the usual appearance of sanguine plethora in persons of a spare and slender make, will explain the plumpness of figure and glossiness of skin which so peculiarly mark the species before us. In the first, there is great and universal vig- our and rapidity of action ; the secretions are all hurried forward in their elaborations, and carried off as soon as produced. In the sec- ond, there is little vigour or activity of any kind, and whatever is eliminated is suffered to accumulate. Hence costiveness is a com- mon symptom; the ankles are cold and pituitous; and the animal oil, when once separated and deposited in the chambers of the cel- lular membrane, remains there, becomes augmented, and produces corpulency and sleekness. The inertness of the body is communi- cated to the mind ; every exertion is a fatigue; and the mind thus participating in the inertness of the body, the countenance, though fair and rounded, is without expression, and often vacant. Debility is always a source of irritability : and hence there is great irregularity, and a seeming fickleness in many of the symptoms by which this species of plethora is characterized, and the results to which it leads. The bowels, though usually quiescent and costive are sometimes all of a sudden attacked with flatulent spasms or a troublesome looseness. The appetite is languid and capricious ; the heart teized with palpitations, the chest with dyspnoea and wheez- ing ; the head is heavy and somnolent; the urine pale, small in quantity and discharged frequently. In this species, as in the last, we are compelled to begin with eupping or the use of the lancet. But, though the distended and overflowing vessels demand an abstraction of blood, it should never GE. I.-SP. II.] SANGUINEOUS FUNCTION. 455 be forgotten that the relief hereby afforded is only temporary; and that, as the disease is, in this case, an effect of debility, we are directly adding to the cause as often as we have recourse to the lancet. Our leading object should be to give tone to the relaxed fibres; and to take off the morbid tendency to the production of a surplus of blood by counteracting the irritability which gives rise to it. Our attack must be made upon the entire habit, which as far as possible should undergo a total change. The diet should be nutri- tious, but perfectly simple, and the meals less frequent or less abund- ant than usual; the sedentary life should give way to exercise at first easy and gentle, but by degrees more active, and of longer ex- tent or duration. Tonics, as bitters, astringents and sea-bathing, may now be employed with advantage ; and the muscular fibres will become firmer as the cellular substance loses its bulk. The whole, however, must be the work of time; for although in morals it is a wholesome principle that bad habits cannot too speedi- ly be thrown off, it is a mischievous doctrine in medicine. Health being the middle term between excess and deficiency, every day is giving us a proof that where either of these extremes has become habitual, the system can only be let up or let down by slow degrees so as to reach and rest at the middle point with certainty, and with- out inconvenience. Professor Monro has furnished us with several very striking examples of this fact; and particularly among those who had acquired a habit of drinking very large quantities of spiri- tuous potation. A man of this description who had broken both bones of one leg, and was put, for a more speedy recovery, upon a diet of milk and water and water-gruel, was hereby thrown into a low fever with an intermitting pulse, twitching tendons, and deliri- um ; during which he got out of bed and kicked away the box in which his leg was confined. A by-stander and friend of the patient's of the same irregular habit, ventured to tell the professor that he would certainly kill him if he did not allow him ale and brandy; since, for several years antecedently, he had been accustomed to both these as his common drink; a little of each was, in consequence, permitted him ; but the patient's friends did not tie him down to this little; for extending the grant of an inch to an ell, they instantly gave the man a Scot's quart of ale and a gill of brandy, which was his usual allowance for the evening, he slept well and sound ; the next morning was free from delirium and fever; and, by a perse- verance in the same regimen, obtained a speedy cure without the least accident.* * Edin.

The term haemorrhagia, or hemorrhage, is derived from the Greek xtftx, " sanguis," and pV*-*, " rumpo." Dr. Cullen has adopted the same name for an order of diseases; but there are few parts of his arrangement that are more open to animadversion, and which in fact have been more animadverted upon than the present. The order of hemorrhages, or fluxes of blood, ranks in Dr. Cullen's sys- tem under the class pyrexia, or febrile diseases. Pyrexy, however. is only an accidental symptom in idiopathic hemorrhages of any kind, and has hence been omitted by all, or nearly all, other noso- logists in their definitions: while Dr. Cullen himself has found it impossible to apply it to many hemorrhages, among which are all those that are called passive ; and he has hence been obliged to transfer the whole of these to another part of his system, notwith- standing their natural connexion with the active, and to distinguish them by the feeble name of profusions, instead of by their own pro- per denomination. Blood, from whatever organ it flows, may have two causes for it- issue. The vessels may be ruptured by a morbid distention and impetus; or they may give way from debility and relaxation, their tunics breaking without any peculiar force urged against them, or their exhalents admitting the flow of red blood, instead of the more attenuate serum. To the former description of hemorrhages, Dr Cullen has given the name of active; to the latter that of passive. The distinction is sufficiently clear; and, under the names already employed in the preceding genus of this system, will lay a founda- tion for the two following species :— 1. K&MORRHAGIA ENTON1CA.

ACCOMPANIED WITH INCREASED VASCULAR ACTION: THE BLOOD FLORID AND TENACIOUS. *s the outlets of the body are but few, and all of them communi- cate with numerous organs, we cannot a ways determine with strict accuracy from what particular part the discharge flows. We have, however, sufficient reason for the following varieties:— x Narium.

I Proctica. ------■ a"al hemorrhage. The great predisponent cause of active hemorrhage, wherever it makes its appearance, is plethora or congestion A plethoric dia- thesis will, however, only predispose to a hemorrhage somewhere or other; and hence there must be a distinct local cause that fixes it upon one particular organ rather than upon another. The chief local cause is a greater degree of debility in the vessels of such or- o-an than belongs to the vascular system generally. But there are other and more extensive causes that operate upon some organs, and which consist in an unequal distribution of the blood and its peculiar accumulation in some vessels rather than in others. Ihus, some organs acquire developement and perfection sooner than others, ot which the head, peculiarly large even in infancy, furnishes us with a striking example : and, in the promotion of such developement, the flow of the blood is directed with greater force and in greater abundance. And hence, while the coats of the blood-vessels in this organ are yet tender, and destitute of that firmness which they de- rive from age, we have reason to expect hemorrhage as a frequent occurrence and particularly from the vessels of the nostrils; be- cause there is in the nose, for the use of the olfactory sense, a con- siderable net-work of blood-vessels expanded on the internal suriace of the nostrils, and covered only with thin and weak integuments. And, on this account, we see why young persons are so much more subject to bleedings from this organ than those in mature lite Hae- moptysis, or spitting of blood, takes place more commonly a few vears later, and when the animal frame has acquired its full growth, and consequently the vascular system its full extent or longitude. Antecedently to this, the impetus and determination of blood are VOL. H. 58 458 HiEMATICA. [CL. III.-OR. IV. greater in the aorta and its extreme ramifications than in the pul- monary artery, because more of the vital fluid is demanded for the progressive elongation of the very numerous arteries that issue from the former: and, consequently, a greater tendency to plethora ex- ists in this direction till the age of about fifteen or eighteen than in the direction of the lungs. .Till this period of life, therefore, we have no reason to expect hemorrhage from the respiratory organs. When this term, however, has arrived, the bias is thrown on the other side; and the vessels of the corporeal ami of the pulmonary circulation being equally perfected, the tendency to accumulation will be in the latter, in consequence of their shorter extent. This tendency will continue till about the age of thirty-five ; which is exactly correspondent with the observation of Hippocrates, who has remarked that haemoptysis commonly occurs between the age of fifteen and that of five-and-thirty. We have explained why it does not often occur before fifteen, but what is the reason of its seldom occurring after the latter period ? Dr. Cullen has ingeniously ex- plained it in the following manner. The experiments of Sir Clifton Wintingham, he observes, have shown that the density of the coats of the veins compared with that of the arteries is greater in young than in old animals; from which it may be presumed that the resis- tance to the passage of the blood from the arteries into the veins is greater in young animals than in old; and while this resistance con- tinues, the plethoric state of the arteries must be perpetually kept up. The very action, however, of an increased pressure against the coats of the arteries gradually thickens and strengthens them, and renders them more capable of resistance ; whence in time they come not only to be on a balance with those of the veins, but to prevail over them; a fact which is also established by the experiments just adverted to. After thirty-five, therefore, the constitutional balance becomes completely changed, and the veins instead of the arteries are chiefly subject to accumulation. The greatest congestion will usually, per- haps, be found in the vena portarum, in which the motion of the venous blood is slower than elsewhere ; and such congestion alone will frequently act upon the neighbouring arteries, and induce what may be called a reflex plethora upon them in consequence of their inability of unloading themselves: and hence, the chief origin of haematemesis, anal hemorrhage, and various other hemorrhages from the abdominal and pelvic organs. All these organs, however, are exposed to hemorrhage from inci- dental causes, as well as that constitutional change which has a ten- dency to produce the disease vicariously. Thus, hemorrhage in all of them is occasionally produced by vio- lent exertion, as great muscular force ; vehement anger, or other passions or emotions of the mind; severe vomiting, or coughing; suppressed evacuations of various kinds, especially hemorrhoids of long standing, catamenia, habitual ulcers, issues, or chronic erup- GE.

But in this last case it is probable that the living princi- ple of the stomach is in a state of weakness, as in all other cases in which exotic worms are found to continue alive under its action: since we know that this action when in full vigour is sufficient to destroy oysters, frogs, slugs, leeches, and various other cold-blooded animals in a short time. Haemoptysis is also said by many writers to have been produced by leeches accidentally taken into the sto- mach by a draught of water.f But it is probable that in this case there is a deception : and that the blood discharged by coughing from the trachea has first passed into it from the stomach and mouth. Local stimulants are also an occasional cause. Thus the vessels both of the kidneys and rectum have been excited to hemorrhage by an injudicious use of aloes, terebinthinate preparations, and pun- gent aliaceous sauces. And the former by cantharides, whether ap- plied externally or internally : for Schenck and other writers have given examples of haematuria excited in irritable constitutions by vesicatories alone.§ Occasionally, however, all the various kinds of hemorrhages be- fore us have assumed a different character, and proved salutary and critical. Thus, cephalitis has often ceased suddenly on a free and sudden discharge of blood from the nostrils; pneumonitis, from what has been deemed an alarming haemoptysis; visceral infarc- tions, from a liberal evacuation of the hemorrhoidal vessels; a jaun- dice has been carried off by a profuse haematuria,|| and fevers of va- rious kinds have instantly yielded to a spontaneous appearance of any of them. Such hemorrhages, however, though salutary in their onset, must be cautiously watched; since, if not checked when they have ac- complished their object, they are apt to pass into a chronic or pe- riodic form. Hence many persons have monthly discharges from the rectum; others from the nostrils; others again, occasional or periodic, from the lungs; and a few from the stomach.1T Tulpius gives a case of chronic haemoptysis that continued for thirty years ;** and others, instances of much longer duration.tt There is also another reason for an early attention to spontane- ous hemorrhages; and that is, the profuseness of the discharge • * Percival's Essays, n. p, 181. t Galen.

Dr. Banyer, in the Philosophical Transactions,* gives a case of this sort, in which the discharge was from the bladder; Buchner, another case from the same organ, in which it amounted to not less than four pounds :t and other writers bring examples ol its having proved fatal. The largest quantities, however, are usually lost from the nostrils. Ten, twelve, and upwards of twenty pounds have been known to flowaway before the hemorrhage has ceased. Bartholin mentions a case of forty-eight pounds,^ Rhodius another of eighteen pounds lost within thirty-six hours ;§ and a respectable writer in the Leip- sic Acta Erudita, a third of not less than seventy-five pounds with- in ten days ;|| which is most probably nearly three times as much as the patient possessed in his entire body at the time the hemorrhage commenced. In the Ephemera of Natural Curiosities is a case in which the quantity indeed is not given, probably from the difficulty of taking an account of it, but which continued without cessation for six weeks.1T In active hemorrhages from the nostrils, the epistaxis of many writers, the discharge is usually preceded by some degree of local heat and itching ; and occasionally by a flushing of the face, a throb- bing of the temporal arteries, a ringing in the ears, or a pain or sense of weight and fulness in the head. Yet not unfrequently the blood issues suddenly without any of these precursors; for, as we have already observed, the arteries distributed over the schneide- rian membrane are very numerous and superficial, and a very slight irritation is often sufficient to rupture them. That insolation or ex- posure to the direct rays of the sun, a cold in the head, or cold ap- plied to the feet or hands, coughing, or sneezing, especially upon the use of sternutatories, an accidental blow upon the upper part of the nose or forehead, or a jar of the entire frame, as on stumbling, should be sufficient to produce this effect, can easily be conceived; and these, in truth, are the common occasional causes : but it is sin- gular that it should follow, in some highly irritable idiosyncrasies, upon such very trivial excitements as have been noticed by many pathologists. Thus, Bruyerin** gives an example in which the nos- trils flowed with blood upon smelling at an apple ; Rhodius, upon the smell of a rose ;tt and Blancard, upon the ringing of bells :|f and * Voi. xlh. t Miscell. 1728. p. 1496.

We have already observed that the quantity of blood discharged by a spontaneous hemorrhage from the nostrils is sometimes enor- mous. This, however, is a more common result of passive than of active hemorrhage ; and is more usually found in advanced than in early life. If it be evidently connected with entonic plethora, or accompanied with the local symptoms just enumerated, it will afford a more effectual relief than bleeding in any other way, and should not be restrained till it has answered its purpose. Even a small portion of blood, not amounting to more than a table-spoonful or two, when thus locally and spontaneously evacuated, has afforded, on some occasions, a wonderful freedom and elasticity to an oppressed and heavy head : and, when more copious, has probably prevented an apoplectic fit, as it has often formed a salutary crisis in inflammation of the brain, or fevers in which the brain has been much affected. But when these reasons do not exist, the bleeding should be checked by astringent applications. Cold is the ordinary application for this purpose, and it commonly succeeds without much trouble. Cold water may be sniffed up the nostrils, or thrown up with a syringe; but the exertion of sniffing, or even the impetus of the water alone, where a syringe is employed, sometimes proves an excitement that more than counterbalances the frigorific effect. Independently of which there is an advantage in leaving the blood to coagulate on the ruptured orifice of the vessel, which these methods do not allow. By means of a syringe, however, we can throw up, when necessary, astringents of more power than cold water, as vinegar, or the sulphuric acid properly diluted, or a solu- tion of sulphate of zinc, copper, iron, or lead, after which we should force up tents of lint moistened with the same, and particularly with extract of lead diluted with only an equal quantity of water, as high as we are able with a probe or small forceps, so as to form a tight compress: the styptic agarics can be rarely used to advan- tage. The face may, at the same time be frequently immersed in ice-water, or water artificially chilled to the freezing point; and the temples, or even the whole of the head be surrounded with a band or napkin moistened with the same, and changed as soon as it acquires the warmth of the skin. When tents are used, they have sometimes been iilined with moistened powder of charcoal, which * Rhodius, Cent. i. Obs. 89. 462 PLEMATICA. [CL. III.-OR. IV. of itself has proved an excellent styptic. Cold applied to the back will succeed, but often fails; it is more certain of success when applied to the genitals. Emetics have occasionally been of service, and are recommended by Stoll.* The principle upon which they may be presumed to act will be noticed under haemoptysis. The bleeding has sometimes been checked by a sudden fright,! probably from the cold sweat that so often attends such an emotion : and Reidlin gives a case in which it was cured by sneezing ;f but this was probably a case of atonic hemorrhage, in which the spasmodic action might assist in corrugating the mouths of the bleeding vessels. It is rarely necessary or even proper in this variety of hemorrhage to employ any internal astringent or other tonic : but if this discharge should be excessive, and produce debility, the same plan may be resorted to as will be recommended under the ensuing species. In hemoptysis or spitting of blood, it is not always easy to deter- mine from what vessel or even from what organ the bleeding proceeds : for the blood may issue from the posterior cavity of the nostrils, or from the fauces as well as from the lungs. If, however, from the first, it will cease upon bending the head forward or lying procumbent, and will probably flow from the nose : if from the second, we shall commonly be able to satisfy ourselves by inspec- tion. Blood from the stomach is of a darker colour, thrown up by vomiting, and betrays an intermixture of food. If the haemoptysis be produced from the lungs, and belong strictly to the present species, and more especially if it be a result of entonic plethora, the blood will be chiefly thrown up by coughing; and the discharge will be preceded by flushed cheeks, dyspnoea, and pain in the chest. There is usually, also, a sense of tickling about the fauces, which often descends considerably lower; Salmuth asserts that he has known it extend to the scrobiculus cordis.§ These symptoms, moreover, indicate that the blood flows from a branch of the pulmonary rather than of the bronchial artery. The blood is here of a florid hue, and the hemorrhage sudden and often copious. If a branch of the bronchial artery give way, the flow of blood is usually much slower, and smaller in quantity : there are no precursive symptoms, the blood is rather hawked or spit up intermixed with saliva, and, from being longer in its ascent, is of a darker colour. From its lodgement, however, in the air-vesicles, it becomes a cause of irritation, and a frothy cough ensues, some- times accompanied with a little increase of the pulse and other febrile symptoms, as a feeling of heat and some degree of pain in the breast, which subsides after the ejection, and returns if there be a fresh issue. * Rat.

I.] SANGUINEOUS FUNCTION. 463 If the structure of the lungs be sound, we have no reason to prognosticate danger. On the contrary, it often affords great relief to a gorged liver, and has proved critical in obstructed menstruation. Excreted with the sputum it is frequently serviceable, as we have already observed, in cases of asthma, pleurisy, and peripneumony. But if it have been preceded by symptoms of phthisis, or a strumous diathesis, there is great reason for alarm ; for we can have little hope that the ruptured vessel will heal kindly and speedily, and have much to fear from the fresh jets, by which the extravasated blood becomes deposited and forms a perpetual stimulus in an irritable organ. The general pathology has been already laid down. The incidental causes are misformation of the chest; undue exertion of the respiratory muscles, whether in running, wrestling, singing, or blowing wind-instruments; excess in eating and drinking; or a violent cough. As a symptom or sequel, it occurs in wounds, phthisis, or the suppression of some accustomed discharge. In active hemorrhage from the lungs, venesection is one of the most important steps towards a cure ; and the blood should be drawn freely at once, rather than sparingly and repeatedly; though a second and even a third copious use of the lancet will often be found expedient. Emetics have been recommended, but they are of doubtful effect. They augment the vascular volume by relaxing the capillaries; but they stimulate locally by the act of rejection. Drastic purgatives are avoided because of the straining; but the straining in vomition is greater and more direct. Dr. Brian Robinson of Dublin, who was one of the most strenuous promoters of this mode of practice in his day, accounted for the benefit of emetics by the constriction which he conceived they produce upon the extreme vessels every where ; but to act thus they should rather nauseate than vomit; for in nausea we have great vascular depression, and a cold and general collapse on the surface ; while vomiting is known to rouse the system generally and determine towards the surface. Upon the recommendation of Dr. Robinson, Dr. Cullen followed the plan in several cases : " but in one instauce the vomiting," says he, " increased the hemorrhage to a great and dangerous degree ; and the possibility of such an acci dent again happening has prevented all my further trials of such a remedy."* Nauseating has on this account been preferred on the continent to full vomiting in hemorrhage from the stomach, and indeed various other organs as well as from the lungs; and ipeca- cuan in small doses has been generally preferred to the metallic salts, as more manageable ; half a grain or even a quarter of a grain being given every quarter of an hour for many hours in succession.! In general, however, we shall find it as successful and far less * Mm. Med. Part n. Ch. xix. p. 470. + Keck, AbhauJlung, und Beobacbtungen. MedinUches Wochenblr.tt. 173:'\ No. 49. 464 HJEMATICA. [CL. III.-OR. IV. distressing to employ mild aperients and sedatives. The first, and particularly neutral salts, are alone of great benefit, and their action should be steadily maintained. Sedatives are of still higher impor- tance, and especially those that reduce the tone of the circulation, as nitre and digitalis. The first, in about ten grains to a dose, should be given in iced water, and swallowed while dissolving; the dose being repeated every hour or two according to the urgency of the case. If there be much cough, it must be allayed by opium and blisters. Local astringents we cannot use, and general astringents are here manifestly counter-indicated, however useful in passive hemorrhage : though it should be recollected, that when an active hemorrhage from the lungs is profuse and obstinate, the vessels lose their tone and fall into a passive state. In h-ematemesis the blood is evacuated from the alimentary canal at either extremity, whether that of the mouth or of the anus: for the term is used thus extensively by the Greek writers. In both cases it is discharged in active hemorrhage with a considerable expulsive effort; and the discharge is preceded by tensive pain about the stomach ; and accompanied with anxiety and faintness. The quantity discharged from the stomach is in most cases larger than what is discharged from the lungs, and of a deeper hue : it is also thrown up by the act of vomiting, and usually intermixed with some of the contents of the stomach. And hence, there is no great difficulty in determining as to the source of the hemorrhage. Haematemesis, however, is far more frequently a disease of atony than of entony, and hence chiefly belongs to the next species. Its usual exciting causes, when it occurs under an entonic character, are concussion or other external violence, as a shock of electricity,* some strong emotion of the mind, as rage or terror, vomiting, or pregnancy. It has also occasionally been found, and often affords relief, in suppressed catamenia. The pathology we have already given; the blood may proceed from the spleen, the liver, the pancreas, the stomach itself, or the smaller intestines; and the mode of treatment should be as already advised for haemoptysis. In hematuria the blood is evacuated at the urethra; and the evacuation is preceded by pain in the region of the bladder or kidneys, and accompanied with faintness. The blood is sometimes intermixed with urine, but occasionally flows pure and uncombined: and in this last state the disease is called by Vogel stymatosis, and the bleeding is supposed,to proceed from the bladder rather than from the kidneys ; that from the latter being smaller in quantity, and remaining a longer time in the passages, and consequently of a darker colour. There is some ground for this opinion ; for when the bladder is the seat affected, there is far more local pain and faintness, than where the affection is in the kidneys. Hippocrates, indeed, has observed, that where the blood flows pure, copiously, * PcrcivaPs Essays, Vol. n. p. 181. GE. II.-SP. I.] SANGUINEOUS FUNCTION. 465 and suddenly, and without*pain, it proceeds from the kidneys; hut where it is small in quantity and of a blackish colour, and accompanied with much heat or pain, or both, its source is the bladder. But this remark, instead of opposing, tends rather to corroborate the preceding; for according to both views the seat of disease is distinguished by the greater or less degree of uneasiness that attends the discharge ; and this whether the quantity discharged be larger or smaller. It is not often, though sometimes, an entonic disease or an active hemorrhage. Its exciting cause is frequently a stone in the bladder; or a violent blow on the kidneys, or on the bladder, especially when the latter is full. It is also said by Schenck* and other writers to be occasionally produced by cantharides whether employed exter- nally or internally; for vesicatories alone are accused of occasion- ally exciting this complaint in irritable constitutions.! In connexion with the general course of treatment already re- commended in the preceding varieties, the compound powder of ipecacuan may here be employed with great advantage; for the pain and irritation are often intolerably distressing, and on this ac- count demulcent drinks are frequently found to produce considera- ble relief. In uterine hemorrhage the blood is discharged from the womb with a sense of weight in the loins, and of pressure upon the vagina. This is the menorrhagia of most of the nosologists, and is often, but very erroneously, described as an excess of the menstrual flux. It is in truth a real hemorrhage or issue of blood, instead of menstrual secretion, which is often entirely suppressed, though sometimes a small but inadequate portion is intermixed with the uterine bleed- ing : and hence Hoffman has properly denominated it uteri haemorr- hagia. It occurs both in an entonic and an atonic state of the ves- sels, and especially of the general system: and from the remarks of- fered under Plethora, it is not at all to be wondered at, that he- morrhage should in both conditions take place from the uterus very frequently, and perhaps more so than from any other organ. For reasons we shall have occasion to explain in a subsequent part of this work, the uterus, from the period of the completion of the female form, is stimulated, once in every lunation, to the secre- tion and elimination of a peculiar fluid, which exhibits the colour, though it is deficient in many of the properties of blood; and for this purpose the uterine arteries are, at such seasons, peculiarly turgid and irritable. There is hence always a tendency on such occasions to an hemorrhage in this quarter in females of a firm and robust texture, and of a plethoric habit. But if from cold or any other cause the uterine secernents do not at these seasons fulfil their office, and throw forth the proper fluid, the uterine arteries will be inordinately gorged ; the regular stimulus will be greatly augment' * Lib. vn. Obs. l. 24. ex Langio. t Hist. Mort. Uratislav. p. 58. 59 VOL. II. 466 H/EMATICA. [CL. III.-OR. IV. ed; pain, tension, and spasm will extend over the loins; and the ex- tremities of the vessels be ruptured, or their mouths give way by anastamosis ; and a considerable hemorrhage be the consequence. This is the ordinary period in which uterine hemorrhage takes place; though it may occur during any part of the interval between the catamenial terms, upon any of the occasional causes that operate upon other organs, and from the preceding varieties : as it * also well known to occur at times, with great violence, during pregnan- cy and in child-bed. When we come to treat of diseases appertaining to the sexual organs, we shall have to notice some singular cases of precocity in female infants, and especially that of a regular menstruation. It is upon this principle alone that we can account for uterine hemorr- hage in new-born infants; of which the medical records give seve- ral examples; and especially the Ephemerides of natural Curiosities. In suppressed menstruation uterine hemorrhage affords relief to the spasms and pains that harass the loins, and the head-ache and difficulty of breathing which have usually preceded the lumbar dis- tress. But the discharge may be immoderate, and become habitual. And it is hence best to be upon our guard, and to use venesection as a substitute ; and to prevent or diminish the spasmodic action by gentle aperients and the sedatives already recommended in haemop- tysis ; after which the case will become a disease of suppressed mensti uation alone, and must be treated according to the method recommended under that malady ; for a restoration of the catamenial secretion is its natural cure. I may here, however, observe, that when the suppression of this secretion has been of some standing and an uterine hemorrhage has periodically taken its place, accom- panied with distressing pains in the whole circle of the pelvic re- gion, we can sometimes suddenly restore a healthy action to the organ by a plan of anticipation. For this purpose I have prescrib- ed venesection about ten days before the return of the monthly paroxysm; and having thus taken off the plethoric impetus. I have, a few days afterwards, recommended the hip bath to be used in a tepid state, every night, and persevered in till the period of relapse; when I have often found that there has been neither tension nor spasm; that the loins have continued easy, and the hemorrhage has yielded to the natural secretion. In hemorrhage strictly ,anal, the flux of blood issues chiefly from the haemorrhoidal vessels; and as these are large, and but little sup- ported by any surrounding organization, they readily give way both in an entonic and atonic state of the frame, and particularly in case of plethora, upon very slight excitements ; as in straining to expel hardened feces, taking cold in the feet, or walking a little too far Irritants introduced by the mouth have also proved a frequent cause of this variety of hemorrhage ; as an injudicious use of aloes, tere- bmthinate preparations, or even pungent aliaceous sauces. The irritation ot piles is also a very common cause; and hence by some writers anal hemorrhage is only treated of as a symptom of that GE. II.-SP. I.] SANGUINEOUS FUNCTION. 467 variety of this last disease which is known by the name of bleeding piles. But this is highly incorrect; as anal hemorrhage often oc- curs, and very profusely, where no piles have ever been expe- rienced. This power of hemorrhage when active, as it is called, or in an entonic habit, is usually preceded by a sense of weight and pain within the rectum, and sometimes by a load in the head. And it has often, as already observed, proved critical and salutary, and car- ried off congestions from the abdominal viscera. It is however, peculiarly apt to become profuse, and to establish an order of re- currence ; and hence must be overpowered by the reducent and sedative plan recommended in most of the preceding varieties, and particularly in that of haemoptysis. The aperients employed, how- ever, should here be-peculiarly mild and alterant; and sulphur, which does not readily dissolve in the course of the intestinal canal, and often reaches the rectum in an unmixed state, is one of the best, and is often found strikingly serviceable. All stimulant foods, more- over, must be especially avoided; and the ordinary drink should be water, soda-water, or lemonade. Here also we are able, as in the case of hemorrhage from the nose, to employ local astringents, though it would be improper to use those that act generally, so long as plethora or an entonic habit continues. The patient may sit in a bidet of ice-water or water cool- ed artificially to the freezing point, or may use a cold hip-bath, and have injections of cold-water, or astringent lotions, as of alum, zinc, or even lead, thrown up the rectum ; the latter of which should be in such proportion as to remain there for half an hour or an hour.

Though the effect in this species is the same as in the preceding, the proximate cause, as well as the more obvious signs, are directly opposite. The general pathology has been given in the introducto- ry remarks to the genus, and the more common organs from which the hemorrhage proceeds are the same as already noticed under the preceding species; and hence the varieties of that may be regarded as thoso of the species before us. When plethora is the remote cause, which it often is, it is atonic plethora, or plethora of debility; but whatever has a tendency to 468 tLEMATICA. [CL. I1I.-OR. IV. loosen or enervate the tone of the solidum vivum, or living fibre, will lay a foundation for this kind of hemorrhage. It is hence a characteristic disease of advanced age, as entonic plethora is of youth and adult life ; and often takes place in those whose vigour is reduced by meagre or innutritious food, close confinement without exercise in a foul and stagnant atmosphere, or immoderate indul- gence in the pleasures of wine or sexual intercourse. Hence too its frequent occurrence, as a symptom, in tabes, atrophy, struma, scurvy, and low fevers. The characters of the several varieties of this species, as distin- guished from those of the preceding, are as follows :— In hemorrhage from the nostrils, the blood flows without heat or head-ache. In that from the respiratory organ, it is usually produced with- out even the exertion of coughing, and is often accompanied with a scirrhous or calculous affection of the lungs ; the countenance is pale and emaciated. In hemorrhage from the alimentary canal, the blood is discharg- ed without tensive pain : though there must necessarily be an ex- pulsive effort; and, from the inanition hereby produced, some de- gree of nausea and faintness. When evacuated by the urethra, there is, for the same reason, faintness, but little or no previous pain. The most singular and severest examples of hemorrhages from the urethra are those that have occurred during coition; sometimes intermixed with semen, sometimes instead of it, and sometimes immediately after emission. The individuals have been generally persons of highly irritable and delicate habits; and who have weakened themselves by too free an indulgence in pleasures of this kind. Numerous instances of this sort of hemorrhage are given in the Collections of Medical Curiosities, and especially in several of the German Ephemerides. There is little pain in atonic hemorrhage from the uterus : and it generally occurs at the natural cessation of the menstrual flux, or within a few years afterwards. As a concomitant, hemorrhage from this quarter is also frequently found in a scirrhous, cancerous, or other morbid states of the uterus, in whatever period of life these may occur ; whiofi, however, they do most usually after the age of forty or fifty. Atonic hemorrhage from the anus usually takes place spontane- ously with little or no pain ; but commonly with varices or conges- tions of the hemorrhoidal vessels, and is very apt to produce a habit of recurrence. In.all these varieties venesection must be had recourse to spar- ingly ; and never, unless where we have satisfactory evidence of atonic plethora or congestion. It may sometimes be requisite to use the lancet in nasal hemorrhage, for the head may feel oppres- sed and drowsy: and it will still more frequently be necessary in hemorrhage from the uterus; but the blood abstracted should rare- ly exceed seven or eight ounces; and in all other varieties, as a GE. II.—SP. II.] SANGUINEOUS FUNCTION. 469 general rule, it will be better to withhold our hand, and to proceed at once with a tonic plan of treatment. Into this plan we may, in the present species, freely admit the use of general astringents in conjunction with their local application, however objectionable in the preceding ; for a laxity and inelastici- ty of the fibrous structure are among the chief symptoms we have to oppose : and hence the mineral acids and metallic salts may be had recourse to with great advantage along with bitters; and, with a few exceptions, we cannot well err in the selection. The prepa- rations of iron may be rather too heating in haemoptysis, and per- haps in all atonic hemorrhages accompanied with much irritability. One of its mildest and best forms is that of a subcarbonate ; and per- haps the best mode of obtaining it in this form is by the celebrated composition of Dr. Griffiths. The myrrh is also in this preparation a useful article for the present purpose, and we shall rarely do bet- ter than employ it. In the London Pharmacopoeia, it is given un- der the name of mistura ferri composita. From the manifest power of opium to restrain most evacuations, it has often been employed in hemorrhages. It does not appear, how- ever, to have any direct effect in checking the discharge ; and in en- tonic hemorrhages, and especially when employed early, has been highly mischievous. But where in haemoptysis there is a perpetual cough from irritation, or in uterine hemorrhages a frequent recur- rence of spasmodic pains, it has been tried with considerable suc- cess. And the same remark will apply to hyoscyamus, and various other narcotics, which seem to be only useful on the same account. Cinchona, which is peculiarly objectionable in the preceding spe- cies, may here be had recourse to with considerable promise. It seems, however, to be chiefly serviceable in uterine hemorrhage, where the disease depends upon a laxity of the extremities of the vessels, which are therefore readily opened by every irritation applied to the system or to the diseased part. Whether in this case it acts altogether as a bitter, as supposed by Dr. CulJen, or partly also as an astringent, it may be difficult to determine; but the ques- tion is not of importance. For other general roborants to which it may be necessary to have recourse, the reader may turn to the treatment of limosis dyspepsia,* or indigestion ; and he may govern the patient's diet and regimen by the general plan there laid down. The local astringents and refrigerants, already recommended un- der the former species, may be here employed with even less re- serve : and when the bleeding has become chronic, which it is far more likely to do than in entonic hemorrhage, or has been so pro- fuse as very considerably to exhaust the system, a little wine or some other cordial should be administered as soon as we are consulted : for, however small the vessel that is ruptured, its orifice is incapa- ble of contracting from a total loss of tone : and hence a diffusible * Class i, Ord. i Vol. t. p. 111. 120. 470 HiEMATlCA. [CL. III.-OR. IV. stimulus gives it the irritation it stands in need of, and forms a salu- tary constringent. A striking case of this kind has already been given in treating of accidental hemorrhages from extracting teeth: and it is only a few weeks ago since the author was requested to at- tend in a similar hemorrhage from the nose. The patient was a lady of about fifty years of age, of slender and delicate frame, who had for some years ceased to menstruate. The bleeding had con- tinued incessantly for three or four days, during which she had been restrained to a very low diet, and allowed nothing hut toast and wa- ter for her common drink. She was faint, felt sick, and had a fee- ble pulse, and must have lost many pounds of blood, though no ex- act measure had been taken. I gave her instantly a free draught of negus made with port wine, prescribed camphor mixture with the aromatic spirit of ammonia, had the nostrils syringed with equal parts of tincture of catechu and water, and applied a neckerchief wetted with cold water round the temples, directing it to be re- newed every ten minutes. In half an hour the hemorrhage ceased, and on the ensuing day I found no other symptom than weakness, for which a nutritious but inirritant regimen was prescribed. A few days afterwards, the hemorrhage returned from sneezing or some other incidental stimulus, and was restrained, as I was told, for I did not see her, by a recurrence to the same plan. 1 recommend- ed, however, carriage exercise, and an excursion to the sea-coast, which has been complied with, and there has been no recurrence of the disease. To effect the same intention, I have occasionally advised cardiacs combined with astringents in haematemisis, where the discharge of blood has been profuse, and has continued for some days, and the patient has become considerably exhausted : and 1 do not recollect an instance in which the plan has proved unfriendly. In like man- ner, in very great faintness or deliquium produced by a copious and protracted hemorrhage from the uterus, I have had the vagina in- jected with equal parts of port wine and water acidulated with sul- phuric acid, and have found it equally successful. The subacetate of lead is also a preparation which in all such cases ought to be tried internally. It was at one time greatly out of favour from the writings of Sir George Baker and the concurrent opinion of Dr. Heberden. Of the mischievous effects uf various preparations of this metal when employed internally, the former has given numerous examples, and concludes with the following co- rollary : " that lead taken into the stomach is a poison ; I do not say ex proprietate naturae et tota substantia; hut which is capable of doing much more hurt than good to the generality of men in all the known ways of using it: and, consequently, that it cannot be avoided with too much caution.'"! In corroboration of which Dr. Heberden tells us that its good effects are by no means so certain * Vol. I. p. 31. t Med. Transact. Vol. I. p. 311. GE. II.-SP. II.] SANGUINEOUS FUNCTION. 471 as its mischief; and in most cases would be far overbalanced by it. In the form of a subacetate, however, all its evils seem to be sub- dued by a combination'with opium; for the first distinct knowledge of which the medical world is indebted to the penetration and judg- ment of Dr. Reynolds, who tried it, in this state of union, in various cases with the most perfect success, and without the least unfavour- able symptom whatever, whether of pain or even costiveness. He also employed with equal benefit the old tfnctura saturnina, and the sugar of lead ; of the former, giving eighteen drops with three drops of laudanum to a dose, and repeating the dose every four hours in a little barley-water; of the latter, giving one grain with three drops of laudanum mixed into a pill with conserve of roses; to be repeated every six hours. And under both forms he em- ployed these materials with great and unalloyed advantages in hemorrhages of most sorts, especially uterine, pulmonary, and nasal.* Dr. Latham! has since confirmed this practice of Dr. Reynolds in its fullest degree, and even extended its range ; and so little incon- venience has he found from the use of the superacetate that he has employed it " in doses of a grain three times a-day for six, eight, and ten weeks successively ; usually, but not always, combining it with opium or conium; without any other precaution than desiring the patients to obviate any costiveness by oleum ricini or confectio sen- nae." He has occasionally given two grains of the superacetate as an evening dose; once, in consultation with Dr. Reynolds, five grains ; and mentions another case in which he was concerned where ten grains a-day were taken without' any inconvenience. By a mis- take for sugar, a young woman, respecting whom he was consulted, swallowed at one time about two drachms of it, yet without any se- rious evil: the fauces and oesophagus were considerably constring- ed, and this seems to have been the chief mischief; for the bowels were opened by oleum ricini and other purgatives in the course of the day, and the patient was not at all worse for the accident on the ensuing morning. Emboldened by these facts, Dr. Latham has employed the same medicine in other diseases in which irritant astringents and tonics seem requisite, as in colliquative diarrhoeas and hectic perspirations, and more especially in that semipurulent expectoration which too often terminates in pulmonary ulceration and consumption ; and, as he confidently assures us, with great advantage. And he hence concludes that whatever deleterious properties may appertain to lead in some of its salts and oxydes, ndthing pernicious exists in its superacetate; in the process for which he conceives it either to be more completely freed from arsenical or other poisonous minerals than in its other forms, or rendered innocuous by the addition of the acetic acid. * Med.

It only remains to be added, that where entonic hemorrhage has occurred so profusely, or has continued so long as to reduce the system to an atonic state, it then becomes a disease of debility, and is to be treated as though originating under the present species. GENUS 111. MARASMUS. 32mactatfou. GENERAL EXTENUATION OF THE BODY WITH DEBILITY. Marasmus is a Greek term, derived from fix^xim, " maresco," " mar- cescere reddo." It was long ago used collectively to comprehend atrophy, tabes, and phthisis; and in employing it therefore in the present system as a generic name, we only restore it to its earlier sense. The generic character is common to all these subdivisions: for each is distinguished by a general emaciation of the frame ac- companied with debility, and consequently forms a species to maras- mus as a genus. With these species, the reader, however, will find a fourth unit- ed upon a high authority, with which I fully coincide, and to which I shall presently advert. Under the name of climacteric marasmus it is designed to embody that extraordinary decline of all the corpo- real powers, which, before the system falls a prey to confirmed old age, sometimes makes its appearance in advanced life without an\ sufficiently ostensible cause, and is occasionally succeeded by a re- novation of health and vigour, though it more generally precipi- tates the patient into the grave. Extenuation or leanness is not necessarily a disease ; for many persons who are peculiarly lean are peculiarly healthy; while some there are who take pains to fall away in flesh that they may increase in health and become stronger. Eut if an individual grow weaker as he grows leaner, it affords a full proof that he is under a morbid influence ; and it is this influence, this conjunction of exte- nuation with debility, as noticed in the definition, that is imported by the term marasmus, and its synonym emaciation. It is curious to observe, how much more easily the body wastes under a disease of some organs than of others : and it would be a subject of no small moment to inquire into the cause of this, and to draw up a scale of organs effecting this change from the lo ; est to the highest degree. Dr. Pemberton, in a work of considerable merit, published many years ago, threw out some valuable hints upon this subject, which it is to be lamented that he has not sincf GE# IU1 SANGUINEOUS FUNCTION. 473 followed up to a fuller extent. The following passage is well wor- thy of notice, and aptly illustrative of what is here intended. « Let us take " says he, "the two cases of a diseased state of the mesen- teric glands? and 'a diseased or scrophulous affection of the breas . In the former we shall find there is a great emacia ion ; in the lat- er none at all.-ln an ulceration of the small intestines great ema- dalion takes place; in scirrhus of the rectum none- n a disease of the gall-bladder, which is subservient to the liver, the bulk ot the body is rapidly'diminished ; but in a disease of the urinary Mad- der, which is subservient to the kidneys, scarcely ^diminution of bulk is to be perceived. In an abscess of an liver, the body be- Lmes mucreSated; but in an abscess of the kidneys, the bulk 16 "If wetxamfoe into the function of those parts, the diseases of which do or do not occasion emaciation, we may perhaps be led to the true cause of this difference of their effect on the bulk. In or- der, however, to understand more clearly how the functions of these parts bear relation to each other, it may be necessary to premise that the glands of the body are divided into those which secrete a fluid from the blood for the use of the system, and those which se- crete a fluid to be discharged from it. The former may be termed glands of supply ; the latter glands of waste. ° « The smaller intestines, in consideration of the great number of absorbents with which they are provided for the repair of the sys- tem, may be considered as performing the office of glands of sup- ply Large intestines, on the contrary, may be considered as per- forming the office of glands of waste : insomuch as they are furnish- ed very scantily with absorbents, and abundantly with a set of glands which secrete or withdraw from the system a fluid which serves to lubricate the canal for the passage of the feces, and which itself, together with the feces, is destined to be discharged from the sys- tem The glands which secrete a fluid to be employed m the system, as well as the glands of direct supply, may be considered the liver, the pancreas, the mesenteric glands, perhaps the sto- mach, and the small intestines ; and the glands of waste are the kidneys, breasts, exhalent arteries, and the larger intestines. The first set are, in fact, the general assemblage of the chyhfic organs; and it is upon their director indirect inability to carry in- to execution their proper function, that the first of the species we are now about to enter upon, that of atrophy, is founded in all its varieties. How far these remarks will apply to the other species of the present genus is not quite so clear The seat of the second and third may be doubtful, perhaps variable; that of phthisis, or the fourth, admits of no debate. Are the lungs to be regarded as an or- gan of waste or of supply ? The question may be answered in op- posite ways, according to the hypothesis adopted respecting the doctrine of respiration. They throw off carbonic acid gas Do they introduce oxygene or any other vital gas into the circulating system? As an organ of waste, we cannot upon the principle here VOL. IT. 474 HiEMATICA. [Ch. IH^-OR. IV. laid down, account for the emaciation which flows from a diseased condition of them. If it can be substantiated that they are an or- gan of supply, they confirm and extend the principle. Will this principle, moreover, apply in dropsy, in which there is even more emaciation than in phthisis ? The subject is worth enucleating ; but we have not space for it, and must proceed to arrange the four species that appertain to the genus before us:— 1. marasmus atrophia. atrophy. 2. ------■— climactericus. decay of nature. 3.--------tabes. decline. 4.--------phthisis. consumption. *"• All these follow in regular order, as genera or species in most of the nosological arrangements, and are set down as subdivisions of maiccs or marasmus. By Dr. Cullen, phthisis is regarded as a mere sequel of haemoptysis, upon which we shall have to observe in its proper place : while atrophia and tabes are given as distinct dis- eases under the ordinary head, only that for macies or marasmus he employs the term marcores as an ordinal term. The common dis- tinguishing marks are, that atrophy is emaciation without hectic fever; tabes, emaciation with hectic fever; and phthisis, emacia- tion and hectic fever coupled with pulmonary flisease. And such, with the exception of phthisis, is the distinction continued by Dr. Cullen in his Synopsis. But in his Practice of Physic he informs us that his views upon the subject had undergone a change, not only in respect to the subdivisions or varieties of these two diseases, but as to the diseases themselves. " I doubt," says he, " if ever distinction of tabes and atrophia, attempted in the IN osology, will properly apply; as I think there are certain diseases of the same nature, which sometimes appear with, and sometimes without fever."* ' This is written in the spirit of candour that so peculiar- ly characterizes this great man. But I cannot thus readily consent to relinquish a distinction which has received the sanction of so many observant pathologists, and which appears to me to have a sufficient foundation. It is difficult undoubtedly to assign a proper place to all the varieties, or subdivisions of these species; but this is a difficulty common to many other diseases equally; for we per- ceive fevers, nervous affections, and those of the digestive organs, perpetually running into each other in different varieties, while we find it convenient to arrange and describe them as distinct diseases notwithstanding. And, with the caution attempted to be exercised in respect to the species before us, 1 trust that the reader will not discern a greater transgression of boundary in the present than in various other cases of general allowance. ■* Vol. iv.

The specific is a Greek term deduced from x privativa, and rpip« "nutrio," and is literally, therefore, innutrition : a designation pe- culiarly significant, as the disease in all its forms or varieties seems to be dependent on a defect in the quantity, quality, or application of the nutrient part of the blood: and thqs lays a foundation for {he three following varieties: a Inopiae.

Nutrition not sufficiently intro- Atrophy of debility. duced into the blood by the chylific organs, or not sufficient- ly separated from it by the as- similating. In order that the body should maintain its proper strength and plumpness, it is necessary that the digestive organs should be sup- plied with a proportion of food adequate to the perpetual wear of its respective parts: for this wear, as we all know, produces a waste ; and hence the emaciation sustained by those who suffer from famine, in which there is no food introduced into the stomach, or from a meagre or unwholesome diet, in which the quantity intro- duced is below the ordinary demand. It is this condition that forms the first of the subdivisions or varieties, the atrophy of want, un- der which the species before us is contemplated in the present ar- rangement. But the ordinary demand may not be sufficient for the body, or some part of it may be in a state of inordinate wear and waste, as in very severe and protracted labour, in which the supply is rapidly carri- ed off by profuse perspiration, or in rupturing or puncturing a large artery, in which the same effect is produced by a profuse hemorr- hage. Any other extreme or chronic evacuation may prove equal- ly mischievous, as an excessive secretion from the bowels, from the vagina, from the salivary glands, from the breasts; as where a de- licate wet-nurse suckles two strong infants. And hence the origin of the second of the above varieties, or the atrophy ok waste. 476 HEMATIC A. [CL.IH.-0R.1V Now, in all these cases, wherever the sytem is in possession of an ordinary portion of health, there is a strong effort made by•the di- gestive powers to recruit the excessive expenditure by an addition- al elaboration of nutriment; and the instinctive effort runs through the entire chain of action to the utmost reach of the assimilating powers, or those secernents with which every organ is furnished to supply itself with a succession of like matter from the common pabulum of the blood. Hence the stomach is always in a state of hunger, as in the case of famine, profuse loss of blood, or recovery from fever; all the chylific organs secrete an unusual quantity of resolvent juices, an almost incredible quantity of food is demanded, and is chymified, chylified, and absorbed almost as soon as it enters the stomach; the heart beats quicker, the circulation is increased, and the new and unripe blood is hurried forwards to the lungs, which more rapidly expand themselves for the purpose, to be completed by the process of ventilation: in which state it is as rapidly laid hold of by the assimilating powers of every organ it seems to fly to, and almost instantly converted into its own substance. Such is the wonderful sympathy that pervades the entire frame ; and that runs more particularly through that extensive chain of ac- tion which commences with the digestive and reaches fo the assi- milating organs, constituting its two extremities. So long as the surplus of supply is equal to the surplus of ex- penditure, no perceptible degree of waste ensues; but the greater the demand, the greater the labour, and the turmoil is too violent to be long persevered in. The excited organs must have rest, or their action will by degrees become feeble and inefficient. And if this take place while the waste is still continuing, emaciation will be a necessary consequence even in the midst of the greatest abun- dance : and we hence obtain an explanation of the variety of ema- ciation before us. Thus far we have contemplated the animal frame in a firm and healthy constitution : and have supposed a general harmony of ac- tion pervading every link of the extensive chain of nutrition from the digestive organs to the assimilating powers. But we do not al- ways find it in this condition; and occasionally perceive, or think we perceive, that this necessary harmony is intercepted in some part or other of its tenor: that the digestive powers, or some of them, do not perform their trust as they should do or that the assi- milating powers, or some of them, exhibit a like default; or that the blood is not sufficiently elaborated in its course, or becomes loaded with some peculiar acrimony. And hence another cause, or rather an assemblage of other causes, competent to the disease before. It is from the one or the other of these sources that we are in most, perhaps in all, cases to derive the third modification of this disease, which is here distinguished, for want of a better term, by that of atrophy of debility. The disease under this form is often very complex, and it is difficult to trace out what link in the great GE. III.-SP. I.] SANGUINEOUS FUNCTION. 477 chain of action has first given way. Most probably, indeed, it is sometimes one link, and sometimes another. But from the sympa- thy which so strikingly pervades the whole, we see at once how easy it is for an unsoundness in one quarter to extend its influence to another, till the disease becomes general to the system. Yet I am much disposed to think that the atrophy so conspicuous in feeble habits, and the feeblest periods of life, as infancy and old age, com- mences most usually at the one or the other end of the chain, and immediately operates by sympathy on its opposite. This remark is in consonance with a very common law of life, by which impres- sions are more powerfully and more readily communicated from one extreme of an organ to another, than they are to any of the in- termediate points. It is hence the will operates instantly on the fingers, the stomach on the capillaries of the skin ; and that the irri- tation produced by a stone in the bladder is felt chiefly in the glans penis. And hence the close correspondence which we have already seen prevail between these two extremities of the nutritive function in the case of want and hunger. Where atrophy is connected with a morbid state of the digestive organs, we have a little light thrown on the nature of the disease, but not much. For first, this indigestion does not necessarily pro- duce this effect, since it is no uncommon thing for dyspeptic patients to become plethoric, and gain, instead of lose, in bulk of body. And next, the morbid state of these organs may be a secondary in- stead of a primary affection, and be dependent upon a general hebe- tude or some other unsound condition of the assimilating powers, constituting the other end of the chain; and hence exercising a stronger sympathy over them than over any intermediate organs whatever: as the digestive organs themselves, if the disease should have originated in them, may exercise a like sympathy over the assimilating powers, and hence produce that general extenuation which, as we have just observed, is not a necessary consequence of dyspepsy It is at least put, I think, beyond a doubt, that more than one set of organs is connected in the atrophy of debility. Where this atrophy takes place in infants at the breast or young children, it is ushered in by a flaccidity of the flesh, a paleness of the countenance, sometimes alternating with flushes, a bloated promi- nence of the belly, irregularity of the bowels, pendulousness of the lower limbs, general sluggishness, and debility, and, where walking has been acquired, a disinclination to motion, with fretfulness in the day, and restlessness at night. There is at first no perceptible fever, no cough or difficulty of breathing: but if the disease continue, all these will appear as the result of general irritation, and the skin will become dry and heated, and be covered over with ecthyma, impetigo, or some other squallid eruption. The breath is generally offensive, the urine varies in colour and quantity; and in infants at the breast, the stools are often ash-coloured or lienteric, or greenish, loose and griping. The ap- petite varies; in some cases it fails, in others it is insatiable 478 HJEMATICA. [CL. 111.-011. IV. Where these symptoms, or the greater part of them occur 'to an infant at the breast, it becomes us, in the first place, to be particu- larly attentive to the manner in which it has been nursed, in respect to cleanliness, purity of air, warmth, and exercise : we have next to turn our attention to the nurse's milk; and afterwards to an ex- amination whether the infant is breeding teeth, or has worms, or there be any scrophulous taint in the blood. For the last we have no immediate remedy; the rest we must correct as we find occasion. And if we have no reason to be satisfied upon any of these points, it may still be adviseable to change the milk. It is not easy to de- tect all the peculiarities of milk that may render it incapable of affording full nutrition: and there is reason to believe that one in- fant may pine away on what proves a healthy breast to another. I have given this advice in some dilemmas, and have often found a wonderful improvement on its being followed. In children on their feet, who are confined to the filth and suffo- cating air of a narrow cell, the common habitation of a crowding family, from Sunday morning to Saturday night; or who are pressed into the service of a large manufactory, and have learnt to become a part of its machinery before they have learnt their mother-tongue ; there is no difficulty in accounting for the atrophy that so often pre- vails amongst them. The appetite docs not here so much fail as the general strength ; their meals are, perhaps, doled out at the allotted hours by weight and measure ; but still they are falling vic- tims to emaciation; and are affording proof that air and exercise are of as much importance as food itself; that there are other or- gans than those of digestion upon which the emaciation must depend : and that, unless the supply furnished by the food to the blood-ves- sels be sufficiently oxygenized by ventilation, and coagulated by ex- ercise, the blood itself, however pure from all incidental acrimony or hereditary taint, will never stimulate the secernents of the vari- ous organs to which it travels, to a proper separation of its constitu- ent principles, and a conversion to'their own substance. In all these cases, therefore, the proximate cause seems to be lodged principally in the assimilating powers of the system; and whenever the digestive organs grow infirm also, it is rather by sym-» pathy with the former than by any primary affection of their own. There is a singular case of atrophy quoted by Sauvages, to which he has given the name of lateralis, and which unquestionably be- longs to this variety. It occurred in a young child, and took posses- sion of just one half the body ; the left side, from the axilla to the heel, being so completely wasted that the bones seemed only to be covered with skin, while the right side was fat. Under the influ- ence of topical antispasmodics, and sudorifics continued for seven years, the writer of the account tells us that, he began to get better —" melius habere coepit."* * Nos. Med. CI. x. Ord. i. Ex. Collect. Acad. Torn. in. p. 693 GE. 1II.-SP. L] SANGUINEOUS FUNCTION. 479 In the atrophy of debility common to old age, the cellular mem- brane, that is the containing as well as the parts contained, seems rather to shrivel away, in many cases to be carried away by absorp- tion, and the muscular fibres to become dried up and rigid rather than loose and flabby. In this case the assimilating powers seem to have done their duty to the last, and like an empty stomach when loaded with gastric juice in a moment of sudden death, to have preyed upon and devoured themselves : for it is probable that more than half the bulk of the muscles and of the parenchyma of many of the organs is carried off in the same manner. Here therefore we are to look for the proximate cause of the disease towards the other end of the chain, or among the chylific viscera. And we shall not in general look in vain. Not, indeed, that we shall always, or even * commonly, find it in the stomach or in the liver, for the appetite may not fail, though its demand is but small and it is easily satisfied ; and probably digests what Is introduced into it. Yet here the greater part of the food rests; or rather it passes through the intestines and very little into the lacteals, insomuch that many of our most cele- brated anatomists have thought, as I have already had occasion to observe,* that the mesenteric glands of old people become oblite- rated ; while Ruysch contended that mankind pass the latter part of their Jives without lacteals, and that he himself was doing so at the time of writing. The mode of treatment needs not detain us. Where the disease depends upon a want of wholesome food, or of food of any kind, the cure is obvious: where upon profuse evacuations, it falls within the the precincts of some other disease, and is to be governed by its remedies. And where the cause is an infirm condition of any part of the chain of nutritive functions, from the chylific to the assimilat- ing organs, the same tonic course of medicine that may be advisea- ble in the one case will be equally adviseable in the other. The bowels should be kept in a state of regularity ; mercurial alterants may sometimes be required, though less frequently than under one or two varieties of tabes; the bitters and astringents enumerated under dyspepsy may be had recourse to, according to the peculiarity of the case ; and cleanliness, fresh air, exercise, and cold-bathing will complete the rest. The atrophy of old age is to be met by the richest foods, wine, and the warmth of another person sleeping in the same bed. * Vol. i. p. 282. Parabysma Mesentericum. 480 HiEMATICA. [CL. III.-OR. IV.

For the ground-work of this species of marasmus I am entirely in- debted to Sir Henry Halford's elegant and perspicuous description of it in the Medical Transactions. The disease has hitherto never appeared in any nosological arrangement, but it has characters suf- ficiently distinct and striking for a separate species. In several of its features it bears a strong resemblance to the marasmus or atro- phy of old age described under the preceding species: but it differs essentially in the instances which it affords of a complete rally and recovery : and if the train of reasoning about to be employed in de- veloping its physiology prove correct, it will be found to differ also in its chief seat and proximate cause. The ordinary duration of life seems to have undergone little or no change from the Mosaic age, in which as in the present day it vari- ed from threescore-and-ten to fourscore years. In passing through this term, however, we meet with particular epochs at which the body is peculiarly affected, and suffers a considerable alteration. These epochs the Greek physiologists contemplated as five ; and, from the word climax (*A<^«|), which signifies a gradation, they de- nominated them climacterics. They begin with the seventh year, which forms the first climateric; and are afterwards regulated by a multiplication of the figures three, seven, and nine, into each other; as, the twenty-first year being the result of three times seven; the forty-ninth, produced by seven times seven ; the sixty-third, or nine times seven; and the eighty-first, or nine times nine. A more per- fect scale might perhaps have been laid down; but the general principle is well founded ; and it is not worth while to correct it. The two last were called grand climacterics, or climacterics empha- tically so denominated, as being those in which the life of man was supposed to have consummated itself; and beyond which nothing is to be accomplished, but a preparation for the grave. With the changes that occur on or about the first three of these periods we have no concern at present; and shall hence proceed to that which frequently strikes our attention as taking place about the fourth, or in the interval between the fourth and fifth. This change is of two distinct and opposite kinds; and it is necessary to notice each. We sometimes find the system at the period before us exhibiting all of a sudden a very extraordinary renovation of powers. The GE. 1II.-SP. II.] SANGUINEOUS FUNCTION. 481 • author has seen persons who have been deaf for twenty years abruptly recover their hearing, so as in some cases to hear very acutely : he has seen others as abruptly recover their sight, and throw away their spectacles, which had been in habitual employ- ment for as long a period ; and he has also seen others return to the process of dentition, and reproduce a smaller or larger number ot teeth to supply vacuities progressively produced in earlier life. Under the genus Odontia, in the first class and first order of the present system, several of these singular facts have been already noticed, and examples given of entire sets of teeth cut at this period. That the hair should evince a similar regeneration, of which instances are also adduced in the same place, and of which Forestus affords other examples,* is perhaps less surprising; since this has been known to grow again, and even to change its colour after death.! But I have occasionally seen several of these singu- larities, and especially the renewal of the sight and hearing, or of the sight and teeth, occur simultaneously. And hence Glanville spoke correctly when he affirmed that " the restoration of grey hairs to juvenility, and renewing exhausted marrow, may be effected without a miracle." On the other hand, instead of a renovation of powers at the period before us, we sometimes perceive as sudden and extraor- dinary a decline. We behold a man apparently in good health, without any perceptible cause, abruptly sinking into a general decay. His strength, his spirits, his appetite, his sleep fail equally; his flesh falls away; and his constitution appears to be breaking up. In many instances this is perhaps the real fact; and no human wisdom or vigilance can save him from the tomb. But in many instances also it is an actual disease, in which medical aid and kindly attention may be of essential service ; and upon an application of which we behold the powers of life, as in other diseases, rally; the general strength return; the flesh grow fuller and firmer, the complexion brighten ; the muscles become once more broad and elastic; and the whole occasionally succeeded by some of those extraordinary renovations of lost powers or even lost organs to which 1 have just adverted. The subject is obscure ; and it is as difficult perhaps to account for either of these extremes—for the sudden and unexpected decline, as for the sudden and singular restoration. That the decline however is a real malady, and not a natural or constitutional decay, is perfectly obvious from the recovery. And hence, Sir Henry Halford, in reference to the period in which it occurs, and by which, no doubt, it is influenced, has emphatically denominated it the Climacteric Disease. Under the last species the author observed that the great chain of the organs of nutrition extends from the chylific viscera to the * Lib. xxxi. Obs. 6. + Eph. Nat. Cur. passim. fil 182 HLEMATICA. [CL. III.-OR. IV. assimilating secernents ; that these form the ends of the chain ; that a powerful sympathetic action runs through the whole ; but that this action is more powerful between the one end of the chain and the other, than between any of its intermediate links. He observed further that in the atrophy of old age the failure of action seems to commence and to be chiefly seated at the chylific or chyliferous end, and that the assimilating secernents exhibit the same failure only afterwards and by sympathy : that the lacteals become generally, and sometimes altogether obliterated, while the assimilating process is supported by an absorption, first of the animal oil deposited in the cellular membrane, then of this mem- brane itself, and, lastly, of much of the muscular and parenchymatous structure of the general frame. In the disease before us the reverse of all this seems to take place ; and for its origin we must look to the assimilating powers constituting the other end of the chain. The patient falls away in flesh and strength before he complains of any loss of appetite, or has any dyspeptic symptoms; which only appear to take place afterwards by sympathy. And that the mesentery and lacteals are not paralyzed and obliterated, as in the atrophy of old age, is incontrovertible from the renovation of power and reproduction of bulk that form an occasional termination of the disease. In watching carefully the symptoms of this malady, when totally unconnected with any concomitant source of irritation either mental or bodily, we shall often perceive that it creeps on so gradually and insensibly that the patient himself is hardly aware of its commence- ment. " He perceives," to adopt the language of Sir Henry Halford, " that he is tired sooner than usual, and that he is thinner than he was; but yet he has nothing material to complain of. In process of time his appetite becomes seriously impaired; his nights are sleepless, or, if he get sleep, he is not refreshed by it. His face becomes visibly extenuated, or perhaps acquires a bloated look. His tongue is white, and he suspects that he has fever. If he ask advice, his pulse is found quicker than it should be, and he acknowledges that he has felt pains in his head aud chest; and that his legs are disposed to swell; yet there is no deficiency in the quantity of his urine, nor any other sensible failure in the action of the abdominal viscera, except that the bowels are more sluggish than they used to be." Sometimes he feels pains shooting over different par»ts of the body, conceived to be rheumatic, but without the proper character of rheumatism ; and sometimes the head-ache is accompanied with vertigo. Towards the close of the disease, when it terminates fatally, the stomach seems to lose all its powers ; the frame becomes more and more emaciated; the cellular membrane in the lower limbs is laden with fluid; there is an insurmountable restlessness by day, and a total want of sleep at night; the mind grows torpid and indifferent to what formerly interested it; and the patient sinks at last; seeming rather to cease to live, than to die of a mortal distemper. GE. III.-SP. II.] SANGUINEOUS FUNCTION. 483 Such is the ordinary course of this disorder in its simplest form when it proves fatal; and the powers of the constitution are incapable of coping with its influence. Yet it is seldom that we can have an opportunity of observing it in this simple form, and never perhaps but in a patient whose previous life has been entirely healthy, and whose mind is unruffled by anxiety. For if this complaint, whatever be its cause, should show itself in a person who is already a prey to grief, or care, or mental distress of any kind, or in whom some one or more of the larger and more important organs of the body, as the liver, the lungs, or the heart, has been weakened or otherwise injured by accident or irregularity, oris influenced by a gouty or other morbid diathesis, the symptoms will assume a mixed character, and the disease be greatly aggra- vated. It is these accidents indeed that for the most part constitute the exciting cause, as well as the most fearful auxiliary of the disease ; for, without such, it is highly probable that the predispo- sition might remain dormant; and that many a patient who falls a sacrifice to it would be enabled to glide quietly through the sequestered vale of age to the remotest limit of natural life, and at length quit the scene around him without any violent struggle or protracted suffering, with an euthanasia sometimes though rarely attained, but ardently desired by us all. Sir Henry Halford has remarked that the disease, according to his experience, is less common to women than to men. The author's own experience coincides with this observation. And we can be at no loss to account for the difference, when we reflect on the greater exposure of the latter than of the former to those contingencies which so frequently become occasional causes or auxiliaries, and which, at the period now alluded to, strike deeper and produce a much more lasting effect than in the heigh-day and ebulliency of life. There are some events, however, that apply equally to both sexes, and which very frequently lead to this affection ; and that is, the loss of a long-tried and confidential friend; of a beloved or only child; or of a wife or husband assimilated to each other in habits, disposition, general views and sentiments by an intercourse of perhaps thirty or forty years standing. This last, as it has occurred to me, is a more marked and more frequent cause of excitement than any other. 1 have seen it in some instances operate very rapidly : and have my eye at this moment directed to the melan- choly fate of a very excellent clergyman, between fifty and sixty years of age, the father of ten children, who were all dependent upon him, and whose benefice would have enabled him, in all probability, to provide for them respectably had he lived; but who, having lost the beloved mother of his family while lying-in of her tenth living child, was never able to recover from the blow, and followed her to the grave in less than three months. 1 have at other times seen the same effect produced as clearly and decidedly, though with a much tardier step, and unaccompanied 484 HiEMATICA. [CL. III.-OR. IV. with any sudden shock. 1 attended not long since a lady in Edge-- ware-Road, who died of a consumption at the age of fifty-four. Her husband, though not a man of keen sensibility, had attentively nursed her through the whole of her lingering illness, and had lived happily with her from an early period of life. He was aware of her approaching end, and prepared for it: and, in a few weeks after her decease, seemed to have recovered his usual serenity. Not long afterwards, however, he applied to me on his own account. I found°him dispirited, and losing flesh; his appetite was dimi- nishing, and his nights restless, with little fever, and altogether without any manifest local disorder. The emaciation with its accompanying evils, nevertheless increased, the general disease became confirmed, and in about five months he fell a sacrifice to it. Occasionally, however, where the climacteric temperament, if 1 may so express myself, is lurking, a very trivial accidental excite- ment proves sufficient to rouse it into action. " I have known," says Sir Henry Halford, " an act of intemperance, where intempe- rance was not habitual, the first apparent cause of it. A fall, which did not appear of consequence at the moment, and which would not have been so at any other time, has sometimes jarred the frame into this disordered action. A marriage contracted late in life has also afforded the first occasion to this change " It has in some instances followed upon a cutaneous eruption, of which the following case will afford a very striking example, and show in the clearest colours the general want of tone which under this morbid influence prevails throughout the system. Most pf my readers of this metropolis have beard of, and many of them have perhaps had the pleasure of being personally acquainted with the late James Cobb, Esq. Secretary to the East India Company, the history of whose life, from his intimate and extensive connexion and correspondence with the most brilliant and distin- guished characters of the age that have figured either in political or fashionable life, and more especially from his own fine taste and commanding talents, and his unwearied efforts to patronise merit in whatever rank it was to be found, ought not to have beeil withheld from the world. In November 1816 this gentleman, then in his sixty-first year, and blessed with one of the firmest and most vigorous constitutions that 1 have ever known, applied to me for an erysipe- latous affection of the-face. It was troublesome, and for nearly a fortnight accompanied with a slight fever, and a good deal of irri- tation. It subsided at length, but left a degree of debility which called for a change of air, and relaxation from public duty. He made a short excursion to France, and returned much improved, but evidently not quite restored to ail the strength and elasticity he formerly enjoyed. Insensibly, and without any ostensible cause, he became emaciated, walked from Russel-Square to the East India House with less freedom than usual, and found his earriage a relief to him in returning home. His appetite diminished, his nights were less quiet, and his pulse a little quickened. At one time he GE. III.-SP. H.] SANGUINEOUS FUNCTION. 485 complained of an inextinguishable thirst, and voided an unusual quantity of urine, so as to excite some apprehension of paruria mellita. The urine, however, evinced no sweetness, and both these symptoms rapidly disappeared under the medical treatment laid down for him. The general waste, and debility, however, con- tinued to increase ; his natural cheerfulness began to flag occasion- ally, and exertion was a weariness. At this period an inflammation commenced suddenly on the left side of the nates, which soon pro- duced a tumour somewhat larger than a goose's egg, and suppurated very kindly. Sir Gilbert Blane and Sir Walter Farquhar were now engaged in consultation with myself, as was Dr. Hooper afterwards, it was a doubtful question, what would be the result of this abscess ? It might be regarded as an effort of nature to re-invi- gorate the system by a critical excitement; and in this view of the case there was reason for congratulation. But it was at the same time obvious, that if the strength of the system should not be found equal to this new source of exhaustion, and could not be stimulated to meet it, the abscess might prove highly unfavourable. The tumour was opened, and about a quarter of a pint of well-formed pus discharged: but the morbid symptoms remained without altera- tion, and the cavity seemed rather disposed to run into a sinus along the perinaeum than to fill up. The opening was enlarged, but no advautage followed: it was evident there was too little vigour in the system to excite healthy action. The abscess was alternately stimulated with tincture of myrrh, a solution of nitrate of silver, and red precipitate ; but the surface continued glassy with a display of pale and flabby granulations, that vanished soon after they made their appearance. Mr. Cline was now united in consul- tation, and concurred in opinion that the wound was of subordinate importance, and would follow the fortune of the general frame. The issue was still doubtful, for the constitution resisted pertina- ciously, though upon the whole the disorder was gaining ground. Yet even at this time there was not a single organ we could pitch upon, with the exception of the abscess, that gave indication of the slightest structural disease. The lungs were perfectly sound and unaffected; the heart without palpitation ; the mind in the fullest possession of all its powers; the head at all times free from pain or stupor, even after very large doses of opium and other narcotics: the bile was duly secreted ; the urine in sufficient abundance ; and the bladder capable of retaining it without inconvenience through the whole night. The pulse, however, was quick, the stomach fastidious, and the bowels irregular, sometimes costive, and at others suddenly attacked with a diarrhoea that required instant and active attention to prevent a fatal deliquium. The wound continued on a balance : there was energy enough to prevent gangrene, but too little for incarnation. A clearer example of the disease before us cannot be wished for or conceived. Unfortunately its progress, though retarded by the arms of medicine, was retarded alone. One of the last recommen- 486 HjEMATICA. [cl. III.-OR. IV. dations was a removal into the country: but Mr. Cobb was now be- come so debilitated and infirm, that this was found a work of some difficulty, and required contrivance. His Royal Highness the Duke of Sussex, however, being kind enough to accommodate our patient with the use of his easy and convenient sofa-carriage, for as long a period as he might chuse, he proceeded without much fiitigue to a house provided for him on the borders of Windsor Forest. The distance was now become too considerable for me to attend him statedly, and I visited him but once or twice afterwards. He con- tinued, however, to decline gradually, and, in about a month from the time of his going to Windsor, sunk suddenly under a return of the diarrhoea. In the progress of this disease medicine will generally be found to accomplish but little. The constitutional debility must be met by tonics, cordials, and a generous diet: and a scrupulous attention should be paid to such contingencies of body or mind, as may form an exciting cause, or aggravate the morbid diathesis if already in a state of activity. Congestions must be removed where they exist, and every organ have room for the little play that the rigidity of advanced life allows to it: and where aperients are necessary, they should consist principally of the warm and bitter roots or resins, as rhubarb, guiacum, and spike aloes. In many instances the Bath water, and in a few that of Cheltenham, will be also found of colla- teral use : and especially where we have reason to hope that a be- neficial impression has been made on the disease, and that the sys- tem is about to recover itself. The last remark I shall beg leave to offer, I must give in the words of Sir Henry Halford himself. If not strictly medical, it is of more than medical importance ; and 1 have very great pleasure in seeing it put forth from so high an authority, and finding its way into a professional volume. " For the rest," says he, " the patient must minister to himself. To be able to contemplate with compla- cency either issue of a disorder which the great Author of our being may, in his kindness, have intended as a warning to us to pre- pare for a better existence, is of prodigious advantage to recovery, as well as to comfort; and the retrospect of a well-spent life is a cordial of infinitely more efficacy than all the resources of the me- dical art."

Tabes is a Latin term of doubtful origin. The lexicographers de- rive it from the Greek th*«, kt macero," varied in the Doric dialect to rxxa,—whence Scaliger makes a compound of raxtQtos, " mace- rans vita," " a consuming life, or life of consumption;" and sup- poses that such a word existed formerly, and that tabes is a deriva- tive from it. This is ingenious, but nothing more. Tab-eo, or tab-es, is most probably derived from the Hebrew ^tfjl fab), lite- rally " to pine away or consume ;" which is the exact meaning of the Latin terms. Tabes is sufficiently distinguished from atrophy by the presence of hectic fever; from climacteric decay, by the tendency to de- pressed spirits, as well as its appearing at any age ; and from con- sumption, by the local symptoms of the latter. Its ordinary causes are commonly supposed to be an acrimony in the blood from an absorption of pus, or the introduction of some poi- sonous substance, as quicksilver or arsenic ; or a scrophufous taint; or an irritation produced by excess in libidinous indulgences: thus laying a ground-work for the four following varieties : * Purulenta. Purulent decline. £ Venenata. Decline from poison. y Strumosa. Scrophulous decline. § Dorsalis. Decline of intemperance. In the first of these varieties the absorbed pus may be con- templated as acting the part of a foreign and irritating substance,* and as acting upon a peculiarity of constitution : but unless the latter be present, pus will rarely, if ever, be found to produce a tabid frame : for, as already observed under hectic fever, if absorbed pus be capable, independently of idiosyncrasy, of inducing a decline in one instance, it ought to do in every instance ; yet this we know is not the case, since buboes, empyemas, and other apostems and abscesses of large extent, have been removed by absorption, and yet no tabes has accompanied the process. It is said to occur more frequently where an abscess or a vomica is open ; in consequence of pus becoming more acrimonious by the action of the air. But * Armstrong, Diss, de Tabe purulenta.

IV. this supposition is altogether gratuitous : and where hectic fever accompanies a sore or open abscess, it is more probably from in- creased irritation on the edges or internal surface of the cavity, as already observed when treating on psoas abscess. In tabes venenata, Dr. Cullen conceives that one cause of ema- ciation is produced by an absorption of oil from the cells of the cel- lular membrane into the blood, for the purpose of inviscating the acrimonious spiculae of the poisonous substance. This may perhaps be true in some instances: but by far the greater number of poi- sons that enter the blood, whether by deglutition or inhalation, act by a chemical rather than by a mechanical power. Let them, how- ever, act as they may, the hypothesis is not necessary to account for the emaciation : for the acrimony with which the blood is here- by contaminated, is alone sufficient to excite and maintain the hec- tic ; as the hectic is alone sufficient to wear away the strength and substance of the system, and produces the waste. It is a disease, as Scheffler has observed, chiefly common to miners and mineralo- gists :* and, next to these, is to be found, perhaps, most frequently among the labourers in chemical laboratories. There are other poisonous irritants which are altogether regene- rate or hereditary, that, by their perpetual stimulation, ultimately ■produce the same effect; as those of chronic syphilis, cancer, and scurvy. A more common cause, however, than any of these, is to be found in a state of the system which has apparently a very near relation to that of scrophula, though it is difficult precisely to identify them. The variety from this cause is, hence, frequently treated of under the head of scrophula or struma; but as it is peculiarly connected with a morbid condition of one or more of the organs of nutrition. including those of digestion and assimilation, and is uniformly ac- companied with emaciation, irritation, and some degree of hectic fever, it more properly falls within the range of the genus ma- rasmus than that of struma, and constitutes a peculiar variety of decline. Of all the contaminations that lurk in the blood, and are propaga- ble in a dormant state, that of scrophula, consisting, as for the pre- sent we must allow it to do, in the acrimony before us, shows itself sooner than any of the rest. It is curious, indeed, to observe the different periods of time that hereditary diatheses of a morbid kind demand for their maturity, unless quickened intb developement by some incidental cause. Scrophula very generally shows itself in infancy; phthisis, rarely till at the age of puberty; gout, in mature life-; mania, some years later; and cancer still later than mania Scrophula runs its course first, and becomes dormant, though rarely extinct; phthisis travels through a term often or twelve years, and ifitdonot destroy its victim by the age of thirty-five, generally consents to a truce, and is sometimes completely subjugated.

When the strumous taint is excited into action in infant life, it ge- nerally fixes itself upon the chylific or chyliferous glands, especial- ly when they are in a weakly state; most commonly upon the me- sentery, and to this quarter it often confines itself; insomuch that u I have frequently," says Dr. Cullen, " found the case occurring in persons who did not show any external appearance of scrophula; but in whom the mesenteric obstruction was afterwards discovered by dissection."* It is supposed by Dr. Cullen, and by most patho- logists, that the emaciation is in this case produced invariably by an obstruction of the conglobulate or lymphatic glands of the mesente- ry, through which the chyle must necessarily pass to the thoracic duct. That an obstruction thus total may occur, is not to be alto- gether disputed, because the lymph has been found stagnated in its course by such an obstruction of lymphatic glands in other parts : but I have already observed that it is an interruption of very rare occur- rence ;! so rare, that Mr. Cruikshank affirms he never saw such a stagnation on the dissection of any mysenteric case whatever. And that a scropulous enlargement of the glands of the mesentery does not necessarily produce a total obstruction, is certain, because chil- dren, in whom mesenteric enlargement can be felt in the form of knots protuberating in the abdomen, have lived for a considerable number of years, sometimes ten or twelve, and have at last died of some other disease. And hence, it is perhaps more frequently the hectic fever kept up by the local irritation of the mesentery, and the general acrimony of the scrophulous taint in the blood, that pro- duces the emaciation in this case, than the pressure of a scrophu- lous infarction. " The mesenteric decline," says Dr. Young, " is generally pre- ceded by more or less of a head-ache, languor, and want of appe- tite. It is more immediately distinguished by acute pain in the back and loins, by fulness, and, as the disease advances, pain and tenderness of the abdomen. These symptoms are accompanied or succeeded by a chalky appearance, and want of consistency in the alvine evacuations, as if the chyle were rejected by the absorbents, and left in the form of a milky fluid in the intestines, and the func- tions of the liver were at the same time impaired, the natural tinge of the bile being wanting. The evacuations are also sometimes mixed with mucus and blood; and are attended by pain, irritation, and tenesmus, somewhat resembling those that occur in a true dy- sentery. Occasionally also there are symptoms of dropsy, and es- pecially of ascites; as if the absorption of the fluid, poured into the cavity of the abdomen, were prevented by local obstacles: the ab- sorbent glands, which are enlarged, being rendered impervious, and * Pract. of Phys.'Part.' in.

The appetite is generally good and often raven- ous ; probably produced by some remote irritation acting sympathe- tically on the stomach ; as that of the mesentery, or more likely that of the assimilating powers that constitute the opposite end of the chain of nutrient organs, and which from their morbid excite- ment produce a morbid waste, and demand a larger supply than they receive. As worms are easily generated, and multiply in the digestive organs when in a state of debility, they have often been found in a considerable number in this disease, and have sometimes been mistaken for the cause of the malady instead of the effect.*" Balme gives a case in which they were equally discharged by the mouth and anus.! In the strumous enlargements are occasionally found calcareous concretions, such as often appear in the joints when weakened by arthritic affections,^ or in other weak organs : and hence similar concretions are sometimes discovered in the lac- teals and the liver.§ The decline from an intemperate indulgence in libidinous plea- sures has been denominated tabes dorsalis, from the weakness which it introduces into the back, or rather into the loins, it is a disease of considerable antiquity ; for we find traces of it in the old- est historical records that have reached our own day : and it is par- ticularly described by Hippocrates under the name of $01212 NOTlAS,|| literally "humid tabes," from the frequent and involun- tary secretion of a gleety matter or rather of a dilute and imperfect seminal fluid. He explains it to be, as a disorder of the spinal mar- row, incident to persons of a salacious disposition, or who are new- ly married, and have too largely indulged in conjugal pleasures. He represents the patient as complaining of a sense of formication or a feeling like that of ants creeping from the upper part of his body, as his head, into the spine of his back; and tells us that when he discharges his urine or excrements there is at the same time a co- pious evacuation of semen in consequence of which he is incapable of propagating his species, or answering the purpose of marriage. He is generally short-breathed and weak, especially after exercise : he is sensible of a weight in his head, his memory is inconstant and is affected with a failure of sight and a ringing in his ears. Though without fever at first, he at length becomes severely feverish, and dies of that variety of remittent which the Greeks called leipyria, a sort of causus or ardent fever attended with great coldness of the extremities, but with a burning fire and intolerable heat within, an insupportable anxiety and unconquerable driness of the tongue. * Chesneau, Lib. v.

HI.] SANGUINEOUS FUNCTION. 491 Dr. Cullen does not think that the quantity of seminal fluid dis- charged by undue indulgence can ever be so considerable as to ac- count for this general deficiency of fluids in the body, and the debi- t lity that accompanies it, and adds that we must therefore seek for another explanation of these evils. " And whether," says he, " the effects of this evacuation may be accounted for either from the quality of the fluid evacuated", or from the singularly enervating pleasure attending the evacuation, or from the evacuation's taking off the tension of parts, the tension of which has a singular power in supporting the tension and vigour of the whole body, I cannot po- sitively determine ; but I apprehend that upon one or other of these suppositions the emaciation attending the tabes dorsalis must be ac- counted for."* # It is not difficult to trace this result in a less doubtful and more direct way. The sexual organs, both in males or females, have a close and striking sympathy with the organ of the brain; and the fluid they secrete with the nervous fluid. Whence Willis conceiv- ed that the fluids of both organs are the same, and hence expressly accounts for the debility.! Morbid salacity is no uncommon cause of madness, as we shall have occasion to observe hereafter. Irrita- tion of the uterus shortly after child-birth, is a still more frequent cause of the same mental affection. The testes are not capable of secreting their proper fluid till the sensorial organ has acquired, or is on the point of acquiring, maturity, so that both become perfect nearly at the same time; the mere apprehension of failure when in the act of embracing has at once, in a variety of instances, unnerv- ed the orgasm, and prevented the seminal flow so effectually, that the unhappy individual has often required many weeks or even months before he could recover a sufficient confidence to render the operation complete; while as Dr. Cullen has correctly observed the evacuation itself, even when conducted naturally, produces a plea- sure of a singularly enervating kind. It is in truth a shock that thrills through all the senses; and hence in persons of an epileptic temperament, has been known, as we shall have occasion to observe more fully hereafter, to bring on a paroxysm while in the act of in- terunion. It is hence easy to see that an immoderate excitement of the gene- ric organs, and secretion of seminal fluid must weaken the sen- sorial powers even at their fountain; and consequently that the nervous and muscular fibres throughout the entire frame, and even the mind itself, must be influenced by the debility of the sensorium. This we might suppose if there were no chronic flux from the se- minal vessels. But when we consider the effect often produced on the general frame by the discharge, or rather the irritation of a sin- gle blister; or, which is perhaps more to the purpose, of a small seton or issue, we can be at no loss to account for all the evils that * Pract. of Pliys.

IV. haunt the worn-out debauchee, and especially the self-abuser, from involuntary emissions of a seminal fluid however dilute and spirit- less, in connection with the dreadful debility we have just noticed, and which is the cause of this emission. The nervous irritation which results from this debility is the source of the hectic by which the miserable being is devoured: and hence the heavy terrors and insupportable anxiety, corporeal as well as mental, the sense of for- mication and other phantasms, the flaccidity of the back and loins, the withering of the entire body, the constant desire of erection with an utter inability of accomplishing it, which haunt him by day and by night, and throw him into a state of despondency. A fearful pic- ture, which cannot be too frequently before the eyes of a young man in this licentious metropolis in order to deter him from plung- ing into evils to which he is so often exposed.* Much of the medical treatment it may be proper to pursue has been anticipated in several of the preceding species. The first variety in which the decline is dependent on the stimu- lus of an abscess or sore, or the introduction of pus into the circula- tion, can only be cured by a cure of the local affection. The strength may in the mean while be supported by a course of inirri- tant tonics, as cinchona and the mineral acids, nutritious diet, gentle exercise and pure air. And, if stimulants be at any time employed with a view of acting more directly on the morbid irritation and changing its nature, they should be limited to the milder resins, as myrrh, or the milder terebinthinates, as camphor, and balsam of copaiva. In decline from the inhalation of metallic or other acrimonious vapours, if Dr. Cullen's hypothesis were established, that the ema- ciation is a mere result of the vis medicatrix naturae, and produced by an absorption of oil from the cellular membrane for the purpose of sheathing the minute goads of the poison, it would be our duty to follow up this indication and employ inviscating demulcents, both oils and mucilages. But this practice has rarely been productive of any success: and we have much more reason to expect benefit fr»m a use of the alkalies, which, by uniting with the metallic salts, if they still exist in the circulation, may disengage their acid princi- ples, reduce the metallic base to a harmless regulus, and, by the new combination hereby produced, form a cooling, perhaps'a seda- tive neutral The first step, however, is to remove the patient from the deleterious scene to an atmosphere of fresh air then to purify the blood, whether we employ the alkalies or not, with alter- ant diluents, as the decoction of sarsaparilla, and afterwards to have recourse to bitters, astringents, and the chalybeate mineral waters In strumous decline, the mode of treatment should run precisely parallel with that for most of the species of parabysma, or visceral turgescence, already laid down under their respective heads and Do^alirGiSuy P°n ^ TabCS D°r8aliS' LOnd* ""-BwwW, «»• de Tab.'

A summer's excursion with a cheerful and steady friend, into some un- tried and picturesque country, where the beauty and novelty of the surrounding scenery may by degrees attract the eye, and afford food for conversation, will be the most effectual step to be pursued if the symptoms be not very severe. The hours should be regular, with early rising in the morning, the diet light, nutritive, and invigorat- ing, and a little wine may be allowed after dinner; since it will al- most always be found that the patient has too freely indulged in wine formerly; and he must be let down to the proper point of abstinence by degrees.! The metallic tonics will commonly be found of more use than the vegetable, with the exception of iron, which is generally too heating: though the chalybeate waters may be drunk, if sufficiently combined with neutral salts. The local cold bath of a bidet should be used from the first, and afterwards bath- ing in the* open sea. If the disease have made such an inroad on the constitution that travelling cannot be accomplished; if the mind be overwhelmed, the back perpetually harassed with pain and feebleness, and the nights sleepless with hectic sweats and a frequent involuntary dis- charge, two grains of opium, or more if needful, should be taken constantly on going to bed; diluted acids, vegetable or mineral, should form the usual beverage, and a caustic be applied to the loins on each side. Hippocrates recommends the actual cautery, and that it should descend on each side of the back, from the neck* to the sacrum. Savine bougies have been prescribed by some wri- ters as a topical stimulus ; but a bidet of cold water is preferable ; with injections of zinc or copper, at first not rendered very astrin- gent, but gradually increased in power. * Vol. 282. p. 8.

QEonaumption. COUCH : TAIN OR UNEASINESS IN THE CHEST, CHIEFLY ON DECUMB1TURE : HECTIC FEVER : DELUSIVE HOPE OF RECOVERY. Consumption, or phthisic as it is sometimes called by old medical writers, is by Dr. Cullen contemplated as nothing more than a sequel of haemoptysis, instead of being regarded as an idiopathic affection; and his species, which are two, can only be viewed, and so appear to have been by Dr. Cullen himself, as separate stages in the progress of the complaint; his first species being denominated phthisis incipiens, and characterized by an absence of purulent ex- pectoration ; and his second, phthisis confirmata, distinguished by the presence of this last symptom. This, however, is a very unsatisfactory, as well as a very unscien- tific view of the subject, and evidently betrays the trammels of Dr. Cullen's classification; since he seems to have placed the disease in this position only because he could find no other to receive it: for he admits in his First Lines that, " phthisis arises also from other causes besides haemoptysis."* It is highly probable, indeed, that phthisis occurs, or at least commences, more frequently without hemorrhage from the lungs than with it, and consequently that haemoptysis ought much rather to be regarded as a symptom or sequel of phthisis, than phthisis of haemoptysis. " Haemoptysis," observes Dr. Young, in a work that has the rare advantage of combining great research and learning, comprehen- sive judgment, and a study of the present disease in his own per- son, " is usually enumerated among the exciting, or even among the more remote causes of consumption; but in a healthy constitu- tion, haemoptysis is not materially formidable; and it is conjectured that when it appears to produce consumption it has itself been oc- casioned by an incipient obstruction of a different kind."! So that on the concurrence of the two we may commonly adopt the opinion of Desault, and call it an haemoptysis from consumption, rather than a consumption from haemoptysis.^ Of the three varieties we are about to describe, we shall find haemoptysis a frequent cause of the second, but rarely of either oi the others. These varieties I have taken from Dr. Duncan's very valuable " Observations" on consumption : they are evidently drawn * Part i. Book iv. Ch. i.

Apostematous consumption. y Tubercularis. Tubercular consumption. In the first variety, the cough is frequent and violent, with a copious excretion of a thin, offensive, purulent mucus, rarely mixed with blood; generally soreness in the chest, and transitory pains shifting from side to side. It is chiefly produced by catching cold, or the neglect of a common catarrh. In the apostematous variety, the cough returns in fits but is dry: there is a fixed, obtuse, circumscribed pain in the chest, sometimes pulsatory ; with a strikingly difficult decumbiture on one side; the dry cough at length terminates in a sudden and copious discharge of purulent matter, occasionally threatening suffocation; the other symptoms being temporarily, in a few rare instances perhaps per- manently, relieved. When haemoptysis is the cause, the disease generally appears under this form. In the tubercular variety, the cough is short and tickling; and there is an excretion of the watery, wheylike sanies, sometimes tinged with blood ; the pain in the chest is slight; and there is mostly an habitual elevation of spirits. Usually the result of a scrophulous diathesis. In Dr. Duncan's observations, consumption or phthisis isintroduc- ed as a genus, and consequently the varieties now offered as so many species; yet as the tubercular may run into the apostematous varie- ty, and the catarrhal into both, according to the peculiarity of the constitution, and other concurrent circumstances, and more especi- ally as a common cause may produce all of them in different idiosyn- cracies, the present subdivision will perhaps be found the most cor- rect. Dr. Wilson Philip, has formed another variety (with him species) of consumption, to which he has given the name of Dyspeptic Phthisis, and which he supposes to be produced by a previously diseased state of the digestive organs in which the lungs ultimately participate. u Drunkards," says he, "at that time of life which disposes to phthisis, frequently fall a sacrifice to this form of the disease ; and those who have been long subject to severe attacks of dyspepsia, and what are called bilious complaints, are liable to it.—- What is the nature of the relation observed between the affection of the lungs, and that of the digestive organs in this species of phthisis't is the one a consequence of the other, or are they simultaneous af- fections, arising from a common cause ? they are not simultaneous affections, for the one always precedes the other. In by far the majority of cases in which both the lungs and digestive organs are affected, the affection of the digestive organ precedes that of the lungs. In some instances, we find the affection of the lungs the primary disease: but, in these the case does not assume the form 496 HiEMATICA. [CL. II1.-0R. IV. above described, but that of simple phthisis; and the hepatic affec- tion, which is always the most prominent feature of this derange ment in the digestive organs, does not show itself till a late period of the disease, and then little, if at all influences the essential symp- toms."* These remarks show clearly that phthisis in this form is a sequel of a prior disorder, rather than an idiopathic affection ; and, as . such, needs not be pursued further in describing the present species. It would however be tedious and of no practical use, to notice the different ramifications into which consumption has been follow- ed up by many of the most approved pathologists that have touched upon it. Among modern writers, more especially, it has been very unnecessarily subdivided : thus Bayle gives us six species, derived from supposed organic causes;! of most of which we can know no- thing till the death of the patient; Portal fourteen,]: the first two of which, the scrophulous and plethoric, are peculiarly entitled to attention, while the rest are drawn from other diseases with which it is often complicated, or bf which it is a sequel. In Morton and Sauvages the divisions and subdivisions are almost innumerable. The Greek pathologists are not chargeable with the same error; for in general they treat of the disease, under two branches alone, phthisis, and phthoe; the first importing abscess of the lungs, or the apostematous variety of the present classification, and the se- cond ulceration of the lungs, embracing perhaps the greater part of H^other two. The terms are those of Hippocrates, and they are thus interpreted by Aretaeus.§ Phthisis, as sufficiently appears from the last paragraph^ is a dis- ease of high antiquity as well as of most alarming frequency and fatality. So frequent, indeed, is it as to carry off prematurely, ac- cording to Dr. Young's estimate, and the calculation is by no means overcharged, one-fourth part of the inhabitants of Europe :|| and so fatal that M. Bayle will not allow it possible for any one to recover who suffers from it in its genuine form.1T I can distinctly aver how- ever, that I have seen it terminate favourably in one or two in- stances when the patient has appeared to be in the last stage of the disease, with a pint and half of pus and purulent mucus expecto- rated daily, exhausting night-sweats and anasarca ; but whether from the treatment pursued or a remedial exertion of nature I will not undertake to say. Dr. Parr affirms that he has witnessed six cases of decided phthisis recovered from spontaneously. The ordinary period of the consumptive diathesis is from the age of eighteen to * Trans, of Medico-Chirurg. Soc. Vol. vii. p. 499. t Recherches sur la Phthisie pulmonaire. Par. 1810.

Of the nature of the predisponent cause, we know little more than that it appears to appertain to a peculiarity of constitution which will be noticed presently. The exciting or occasional causes are very nume- rous, as mechanical irritation of the lungs from swallowing a piece of bone ; the dust of metallic or other hard substances perpetually inhaled ; frequent and sudden changes of temperature or exposure Of the body to cold when in a heated state and unprepared for it; overaction in speaking, singing, or playing on a wind-instrument; the irritation of various other diseases, as worms, scrophula, syphi- lis or measles ; the sudden suppression of cutaneous disease that has continued long and formed a part of the habit, as itch; or of any habitual discharge as that of menstruation, or blood from the he- morrhoidal vessels, when the discharge has become periodical: the irritation of a too rapid growth of the body, and that of various pas- sions perpetually preying upon the individual; as mortified ambi- tion, disappointed love, home-longing,! when at remote distance from one's friends and country. Examples of consumption from a mechanical irritation of the lungs are peculiarly numerous, and they furnish cases of every va- riety of the disease according to the habit or idiosyncracy, though the apostematous is less frequent than the rest. So common is th:s complaint among persons employed in dry-grinding, or pointing needles in needle-manufactories, that Dr Johnstone of Worcester informs us they seldom live to be forty, from the accumulation of the dust of the grind-stones in the air-cells of the lungs, and the ir- ritation and suppuration which follows.J It appears to be little less common among knife and scythe-grinders; whence, according to Dr. Simmons, the disease thus originating is called the grinders' rot,§ and Wepfer gives an account of its proving endemic at Wald- shut, on the Rhine, where there is a cavern in which mill-stones are dug and wrought, the air is always hot even in the winter, and a very fine dust floats in it, which penetrates leathern bags, and dis- colours, money contained in them. " All the workmen," says he, " become consumptive if they remain there for a year, and some even in a shorter time ; and they all die unless they apply early * Remarks on the frequency and fatality of different diseases, &c. 8vo.

[CL. 1H.-OR- IV- for assistance."* And, hence, Dr. Fordyce had much reason for regarding the dust of the streets of London, as a serious cause of pulmonic disorders;! though it is a cause that has been much di- minished since the introduction of paving and watering. A lodgement of some fragment of a bone even in the oesophagus has, in like manner, been a frequent cause of phthisis, which has often been protracted through a long period of time. Thus Claubry gives a case of this kind which had continued for fourteen years, and the patient seemed to be in the last stage of a consumption when he was fortunate enough to bring up the piece of bone spon- taneously, in consequence of which he recovered, though for the preceding four years he had laboured under an haemoptysis.^ Mr. Holman describes a similar case that had run on for fifteen years, accompanied with cough, haemoptysis, and hectic diarrhoea; and which was also speedily relieved in consequence of the bony frag- ment, three quarters of an inch in length, and apparently carious, being suddenly coughed up after the discharge of a pint of blood.§ A moderate use of the vocal organs, as of any other, tends to strengthen them, and to enable public speakers, singers, and per- formers on wind-instruments to go through great exertion without in- convenience, which would be extremely fatiguing to those who are but little practised in any of these branches; but the labour is often carried too far, and the lungs become habitually irritated, and hae- moptysis succeeds. I have known this terminate fatally among clergymen; who have lamented, when too late, that in the earlier part of life they spent their strength unsparingly in the duties of the pulpit. Hence, Dr. Young observes from Rammazini,|| that public speakers, readers, and singers, are most liable to pulmonary diseases, and that Morgagni and Valsalva have confirmed the ob- servation. Cicero himself felt it necessary, as he tells us in his book on orators, to retire from the forum for two years, during which he travelled into Asia, and afterwards returned with renewed vigour to the duties of his profession; and Moliere died of haemoptysis, immediately after performing, for the fourth time, his Malade Ima- ginaire.1T There are many diseases that have a peculiar tendency to excite phthisis from their close connexion with the lungs, or affinity to hec- tic fever, which is one of its most prominent symptoms. Thus, ne- glected catarrhs form a frequent foundation, and measles for the same reason. Whether the tubercles found in the substance of the * Observationes de affect. Capitis. 4to.

There is a case by Lissardet, of a fatal con- sumption which succeeded to a psora, supposed to have been too hastily cured ; and another by Coeuvet of a more favourable termi- nation, under similar circumstances, the dartre having re-appeared. It has occurred more than once to myself, that the lungs have been attacked during the cure of cutaneous affections, and, in one i nstance fatally, even where no hasty mode of treatment had been pursued* The tendency of the syphilitic poison to produce phthisis has been noticed by almost every writer from the time of Bennet, who particularly dwells upon it;! but whether this would be adequate to such a purpose without an hereditary predisposition is uncertain. And the same remark may be made respecting worms which Mor- gagni has stated to be a very common cause.J Indeed any habitual irritation, in any part of the alimentary canal seems capable of ex- citing a sympathetic action in the lungs; and hence Wilson in Dr. Duncan's Annals, gives a case of hectic in a child produced bv swallowing a nail two inches long, which remained in the stomach fifteen months, and was then thrown up, and succeeded by a recov- ery of health.§ Rapid growth is always attended with debility and consequent ir- ritability of the entire system; and, where there is a predisposition to consumption, this also becomes often its harbinger, unless great caution is observed on the occasion. Richerand relates a case of this kind that terminated fatally, the individual having grown more than an English foot in a year.|| I have known a still more rapid growth without any other inconvenience than that of languor; but in this case there was no phthisical predisposition. Where the chest labours under any misformation we can readily trace another cause of excitement, and are prepared to meet the examples that from this source so frequently occur to us in prac- tice. But it is less easy to explain by what means persons other- wise deformed, and particularly those who have had limbs ampu- tated, should be more liable to consumption than others ; yet this al- so is a remark that has been made by Bennet,1T though I do not know that it has been supported by concurrent observation. Of all the occasional or accidental causes of phthisis, however, frequent and sudden vicissitudes of temperature are probably the * On Consumptive Diseases, p. 269. t Vestibulum Tabidoruin, 8vo. 1654.

IV. most common; so common indeed, and at the same time so active, as often to be a cause of consumption in constitutions where we can- not trace any peculiar taint or predisposition whatever. Several hundred cases of phthisis from this cause, among which were ma- ny fatal ones, occurred in the channel fleet that blockaded the port of Brest in April 1800, as is particularly noticed by Dr. Trotter. The summer was hot and dry, the duty very severe ; and the sail- ors, wet with sweat, were frequently exposed to currents of air at the port holes; and little time was allowed for refitting * Hence the most frequent examples of consumption are to be found in those countries- 'which are most subject to changes of temperature. In Great Britain, it is calculated that this disease carries off usualfy about one-fourth of its inhabitants; at Paris, about one-fifth ; and at Vienna, one-sixth : while it is by no means common in Russia, and still less so in the West Indies ; for it is checked in both regions by the greater uniformity of the atmos- phere whether hotter or colder.! It is a singular fact, and not well accounted for, that of all places which have hitherto been compared, the proportional mortality from consumption appears to have been the greatest at Bristol; and this, not among its occasional visitors, but its permanent inhabitants; and yet, as though in defiance of experience, this very place has been chosen as the great resort of consumptive persons.^ Nor does its mineral water seem entitled to any higher compliment than its atmosphere. Dr. Beddoes affirms in direct terms that it is of no manner of use ;§ and Dr. Thomas, in more measured language, speaks nearly to the same effect: " In my humble opinion," says he, " the waters of the hot-wells are by no means deserving of the credit ascribed to them; as, during a residence of some time at and near these wells, 1 cannot charge my memory with a single instance where any person, labouring under a confirmed phthisis, experienced much relief from their use alone."1f Where a consumptive diathesis has once originated, it is often very evidently transmitted to succeeding generations; and there is great reason to believe that the disease is in a certain degree contagious. M. Portal, and a few other pathologists of distinction, have doubted or denied that it possesses any such property ; but the apparent instances of communication among near relations and close attentive nurses, and especially between husbands and wives, who have fallen victims to it in succesion, are so frequent, that its contagious power has been admitted by most practitioners and in most ages. Aristotle appeals to it as a matter of general belief * Medicina Nautica. Vol. m. p. 325. t W'oolcombe (Dr. W.) Remarks on the frequency aiid fatality of Diseases, 8vo. Lond. 1808.—Southey (Dr. H.

IV.] SANGUINEOUS FUNCTION. 501 among the Greeks in his day :* and it has since been assented to in succession by Galen, Morton, Hoffman, Vogel, Desault, Darwin, and most modern writers. 1 have myself been witness to various cases which could not be ascribed to any other cause ; and Dr. Rush has given an account of a consumption manifestly contagious, which spread from the pro- prietors of an estate among the negroes, who were neither related to the first victims, nor had been subjected to fatigue or anxiety on their account, and amongst whom it scarcely ever makes its appear- ance.! The disease, however, is but slightly contagious, admitting it to be so at all; and seems to demand a long and intimate com- munion, as, for instance, that of sleeping or constantly living in the same room, to render the miasm effective. Yet, in the present state of the question, most judicious practitioners from the time of Galen have thought it right to follow his advice, and to caution attendants upon consumptive patients against the danger of being constantly about their persons through the whole course of the disease. The diathesis strictly consumptive is usually associated, in the ' language of Hippocrates,! and Aretaeus,§ with a smooth, fair, and ruddy complexion, light or reddish hair, blue eyes, a long neck, a narrow chest, slender form, and high shoulders, or, in the words of Hippocrates, shoulders projecting like wings, and a sanguine dispo- sition. In some instances, however, the skin is dark, and the hair almost black. According to Dr. Withering and Dr. Darwin, the most constant of a consumptive habit is an unusual magnitude of the pupil, to which some have added long and dark eye-lashes ; but this last character seems loose and unestablished. It is a remark far better supported that the teeth are peculiarly clear, and the eyes peculiarly bright; and that both become more so when the disease has once commenced its inroad; the former assuming a milky whiteness, 'and the latter a pearly lustre: showing how completely the animal oil is absorbed and carried off, not merely from the surface, and from the interstices of the muscles by which the form chiefly becomes emaciated, but from every organ what- ever : and, in the appearance of the teeth, affording an additional proof to those already offered when treating of odontia,|| that these peculiar bones are not extraneous bodies, destitute of vascularity, but possessing the same organization as other bones; rendered yellow by a deposit of animal oil, and blanched by its removal. Professor Camper, and most physicians with him, affirm that this appearance accompanies all the varieties of the disease ; but Dr. Foart Simmons limits it to the tubercular alone; and conceives it to * Problem, Sect. i. 7. t Medical Inquiries and Observations, &c.

IV. be a distinguishing characteristic of this form of the disease or of a predisposition to it. And he remarks further, that of those who are carried off by tubercular phthisis, the greater number will be found never 1o have had a carious tooth.* The earliest symptoms of phthisis, in whatever manner excited, are insidious, and show themselves obscurely. The patient is, perhaps, sensible of an unusual languor, and breathes with less freedom than formerly, so that his respirations are shorter and increased in number. He coughs occasionally, but does not com- plain of its being troublesome, and rarely expectorates at the same time : yet if he make a deep inspiration he is sensible of some degree of uneasiness in a particular part of the chest. These symptoms gradually increase, and at length the pulse is found quicker than usual, particularly towards the evening; a more than ordinary perspiration takes place in the course of the night; and if the sleep be not disturbed by coughing, a considerable paroxysm of coughing takes place in the morning, and the patient feels relaxed and enfeebled., This may be said to form the first stage of the disease : and it is the only hopeful season for the interposition of medical aid. The malady is now deciiedly established ; the cough increases in frequency, and from being dry is accompanied with a purulent mucus, varying, according to the peculiar modification of the disease, from a watery whey-like sanies occasionally tinged with blood, to a sputum of nearly genuine pus. It may, as Aretaeus has well observed, be livid, deep-black, light-brown, or light-green; flatten- ed or round; hard or soft; fetid or without smell. In many cases it is very scanty ; and we may also add with Aretaeus that in some consumptions there is no expectoration at all; for in the apostema- tous variety the sufferer has sometimes died before the vomica has broken. The uneasiness in the chest, only perceived at first on making a deep inspiration, is now permanent and attended with a sense of weight: the hectic fever has assumed1 its full character; the patient can lie with comfort only on one side, which is usually the side affected; and the breathing, as Bennet has remarked, is frequently accompanied by a sound like the ticking of a watch. The strength now fails apace ; the pulse varies from about a hundred to a hundred and twenty or thirty; the teeth, from a cause just pointed out, increase in transparency, and the sclerotica of the eye is pearly-whife ; " the fingers, to continue the elegant descrip- tion of Aretaeus as given by Dr. Young, are shrunk, except at the joints, which become prominent; the nails are bent for want of support, and become painful; the nose is sharp, the cheeks are red, the eyes sunk, but bright, the countenance as if smiling; the whole body is shrivelled; the spine projects, instead of sinking, from the decay of the muscles; and the shoulder-blades stand out like the wings of birds." * Practical Observations on the Treatment of Consumptions. By Samuel Foart Simmons, M. D. 8vo. London, 1779. GE. III.-SP. IV.] SANGUINEOUS FUNCTION. 503 The third stage is melancholy and distressing, but usually of short duration. It commences with a depressing and colliquative diarrhoea; but till this period, and occasionally indeed through it, the patient supports his spirits and flatters himself with ultimate success, while all his friends about him are in despondency, and find it difficult to suppress their feelings. The voice becomes hoarse, the fauces aphthous, or the throat ulcerated, with a difficulty of swallowing. Dropsy, in various forms, now makes its approach ; the limbs are anasarcous, the belly tumid, or the chest fluctuating; and the oppression is only relieved by an augmentation of the night-sweats or of the diarrhoea; for it is generally to be found that the one set of symptoms is less as the other is greatej. " A few days before the patient's death, he is frequently unabh/to expecto- rate from apparent weakness, and sometimes dies absolutely suffo- cated : but much more commonly the secretion of pus, as well as the expectoration, has ceased ; as if the capillary arteries had lost their power, or the fluids of the system were exhausted. There is also sometimes a degree of languid delirium for some days, and occasionally a total imbecility for a week or two : though, in gene- ral, the faculties are entire, and the senses acute, the patient being perfectly alive to the danger and distress of his situation, and retain- ing, even when his extremities are becoming cold, a considerable quickness of hearing and feeling. The closing scene is often painful, but it sometimes consists in the gradual and almost imper- ceptible approach of a sleep which is the actual commencement of death."* Such is the common progress and termination of the disease; but it varies considerably in the character and combination of its symptoms, and particularly in the tardiness or rapidity of its march, according to the habit or idiosyncrasy of the individual, or the variety of the disease itself. Where the constitution is firm, and the hereditary predisposition striking, it commonly assumes the apostematous form, and runs on to the fatal goal with prodigious speed, constituting what among the vulgar is called, with great force or expression, a galloping consumption. In this case, the activity of the absorbent, and, indeed, of every other part of the general system is wonderful: the whole frame is in a state of estuation and greedily preying upon itself. The animal spirits are more than ordinarily recruited, and all is hope and ardent imagina- tion ; the secernents play with equal vigour, and the skin is drench- ed with moisture, the bronchial vessels are overloaded with mucus, vomica after vomica becomes distended with pus, and the bowels are a mere channel of looseness. The absorbents drink greedily; and animal oil, cellular membrane, parenchyma, and muscle, are all swallowed up and carried away, till every organ is rapidly reduced to half its proper weight and bulk, and the entire figure becomes a shrivelled skeleton. So swift was the progress of the disease in the * Voung, On Consumptive Diseases, p. 28. f>04 HJEMATICA. [CL. III.-OR. IV. case of the Duchess de Pienne, that M. Portal informs us she died in ten or twelve days from the first alarm. On other occasions, the march of the consumption is as remarka- ble for its tardiness. This is particularly the case with the tuber- cular variety when not quickened in its pace by returns of hemop- tysis. Hoffman gives instances of two or three who lived under the disease for thirty years: and in the Edinburgh communications is the case of an individual who passed nearly the whole of a long life under its influence, who was consumptive from eighteen to seven- ty-two, and died of the complaint at last. Of two hundred cases, however, selected by M. Bayle, a hundred and four died within nine months, whfsh may hence be regarded as the mean term. Dissections seem to prove that the most frequent variety of con- sumption is the tubercular: the tubercles consisting of circumscrib- ed nodules or indurations, by Weffer called grandines,* found indis- criminately in all parts of the cellular texture, but more abundantly at the upper and posterior parts. They are at first very minute, whitish and opake, like small absorbent glands, but sometimes more transparent, like cartilage, with black dots in their substance. They augment by degrees till they are half an inch or more in diameter ; but in general when they have acquired the size of large peas they begin to soften in the centre, and then open by one or more small apertures into the neighbouring bronchiae, or remain for a longer time closed, and constitute small vomicae, containing a curdy half- formed pus. Occasionally they unite into large abscesses.! Now as we have before observed from Dr. Baillie that nothing like a gland is to be found in the cellular membrane of the lungs in a sound state, constituting the seat of these tubercles, and as scrophula se- lects for its abode a glandular structure, tubercular consumption cannot perhaps with strict propriety be called a scrophulous dis- ease : yet as the untempered fluid contained in the tubercles resem- bles that of scrophula, and, more' especially, as this variety of con- sumption is very generally found in constitutions distinctly scrophu- lous, the analogy between the two is extremely close, and has often led to a similar mode of treatment. In some cases, proper abscesses or larger vomicae are found with- out any trace of tubercles ; and especially when the disease has fol- lowed rapidly upon peripneumony, or taken place in persons of ro- bust habits or entonic plethora. And, where the catarrhal symp- toms have been striking, and, in the increasing hoarseness and free discharge of muculent pus, have evinced expensive inflammation on the surface, of the trachea, M. Portal has found the whole extent of the tube lined by a crust resembling bone. In some instances, the lungs, from the accretion of new matter, have weighed not less than five or six pounds, which is nearly four times their ordinary * Sepulchr.

IV.] SANGUINEOUS FUNCTION. 505 weight; but in others, they have been so reduced as in the Ian guage of the same writer to leave u a vacant space" in the chest; or, in that of M. Bayle, to be shrivelled into leather. On this ao* count, breathing would be impossible if it were not that the lungs in a state of health are capable of containing ten times as much air as is received by an ordinary act of inspiration: and hence are ca- pable of losing a very large portion of their capacity without suffo- cation. In some cases, one lung has been entirely destroyed, and the office of respiration maintained by the remaining lung alone for many years.* Many ingenious experiments have been invented to distinguish between pus and mucus, in order to determine the actual nature of the disease. Such trials may gratify the curiosity of the patholo- gist, but from the variable, and frequently complicated nature of the expectoration, as well in the most dangerous as in the earlier stages of the complaint, we can derive little assistance from this distinc- tion. Mr. Hunter, as a test, employed muriate of ammonia, having observed that a drop of pus united with a drop of this fluid is ren- dered soapy, while neither blood nor mucus is affected by it.! Mr. Charles Darwin Heu miserande puer! si qua fata aspera rumpas Tu Marcellus eris— proposed a double test of sulphuric acid, and a solution of pure po- tass. If, on the addition of water to pus dissolved in each of these separately, there be a powerfut precipitation, the matter made use of is determined to be pus: if there be no precipitation in either, it is mucus. But the simplest and truest character of pus, as was first observed and described by Sir Everard Home i*, that it is a whitish fluid composed of globules contained in a transparent liquid ; that it does not coagulate by heat; and is only condensed by alco- hol. The presence of the globules, as remarked by Dr. Young, may be easily determined by putting a small quantity of the liquid between two pieces of plate-glass. If it be pus, we shall perceive^ on looking through it towards a candle placed a little way off, the appearance, even in the day-time, of a bright circular corona of co- lours, of which the candle will be the centre; a red area sur- rounded by a circle of green, and this again by another of red ; the colours being so much the brighter, as the globules are the more numerous and the more equable. If the substance be simply mu- cous, there v/ill be no rings of colours ; though a confused coloured halo may sometimes be perceived by the mixture of mucus with blood or some other material.

IV. thing he conceived more contradictory than the writings upon both these subjects. Boerhaave regarded consumption as a local disease, or conversion of all the blood and chyle into pus by means of an erosive ulcer seated in the lungs: Stahl as a general disease unaf- fected by pus or any other acrimony. The latter ascribed consump- tion to the very abundant use of bark which was then prevailing in Europe : while Morton regarded bark as his sheet-anchor in effect- ing a cure. Consumption, according to Brillouet and many other writers, is identic with scrophula, and is only to be cured by alka- lies, corrosive sublimate, or other mercurial alterants, employed for the cure of scrophulous affections.* According to Cullen, though it has an apparent connexion with scrophula, the analogy affords us no assistance in the treatment, and the remedies for the one are of no avail in the other* Dr. Rush contemplated it for the most part as an entonic or in- flammatory disease, and particularly in its first stage, though it i* sometimes accompanied with a hectic or even a typhous fever. And hence his principal remedies were salivation, or bleeding which he sometimes prescribed fifteen times in six weeks, emetics, nitre in large doses, a milk and vegetable diet, walking in cold air even during an haemoptysis, and afterwards severe exercise. The hardships of a military life, says he, have effected cures in a multi- tude of cases of confirmed consumption ; and a riding post-man has been relieved more than once by the pursuit of his occupation.! This bold practice excited many followers, and was tried with va- riable success upon a large scale. But a practice of an opposite kind equally bold, and which soon became equally popular, was pro- posed at the same time by M. Salvadori of Trent.f Consumption, in the view of this pathologist, is an atonic instead of an entonic disorder from the beginning, a disease of direct debility and not of inflamma- tion ; and hence is only to be cured by an active plan of stimulants and roborants from the first. The patient's diet is to consist of co- pious meals of meat and wine, and his chief regimen to be that of climbing hills, or precipitous steeps in the morning as quickly as he is able, till he is out of breath and bathed in sweat, and then aug- menting the perspiration by placing himself near a large fire. Mr. May, who adopted the same general principle, seems to have post- poned the gymnastic part of the process till the symptoms were al- leviated, and to have called in the aid of medicines which Salvadori regarded as superfluous. May's medicinal means were emetics, bark and laudanum, night and morning ; and for diet, he prescribed soup, meat, wine, porter, brandy and water, eggs, oysters, with proper condiments. Swinging was interposed twice a-day; and horse-ex- cise was to complete the cure.§ * Journ. de Med. 1777. t Med. Inquir. and Observ. i. 8vo. Phil. 1789. n. 1793. v. 1802.

IV.] SANGUINEOUS FUNCTION. 507 Many later writers believe consumption to be very generally pro- duced by a habit of drinking vinegar daily to improve the figure : and Desault relates a case in which this effect was produced in the course of a month.* Galen recommends vinegar as the best refri- gerant we can employ : and Dr. Gregory, in 1794, gave the case of a patient who recovered by using three dozen lemons daily. Dr. Beddoes felt justified in declaring fox-glove a cure for consumption as certain as bark for agues:! Dr Barton affirms he has never known but one case cured by it, though others may have been pal- liated :\ and Dr. Parr asserts roundly that it is more injurious than beneficial.§ Contradictory, however, as are these statements with each other, they are chiefly so, as being either too highly coloured or too in- discriminate. We have already considered phthisis under three va- rieties or modifications, chiefly in respect to it being deeper seated or more superficial; the apostematous lying lowermost, the tuber- cular somewhat higher, and the catarrhal on the surface. But each of these, as it occurs in different constitutions, or under different circumstances, may exhibit very different symptoms and demand a very different, and perhaps an opposite mode of treatment. And hence most of the principles on which the preceding opinions and modes of practice are founded, may derive authority from particu- lar examples of success; and are so far correct, though, perhaps, none of them will apply to the whole. So considerable, indeed, are the shades of distinction from this multiplicity of causes that every separate case of consumption should be allowed to speak for itself, and must call for much deviation from the widest line of treat- ment we can ever propose to ourselves under the form of general rules. The continuance of the disease when once produced may depend, as we took occasion to observe when discussing the nature of hectic fever,|| on the state of the constitution, or on the local irritation; for the hectic may be kept up by either, and so long as this conti- nues we can have no expectation of a recovery. In the first place, the local irritation may be small, while the constitution itself is bad, and does not dispose the parts to a healing condition. And, se- condly, the constitution may be good while the local irritation is so considerable that there is not remedial power enough in the former to subdue it. How far both these principles have been kept in view by pathologists at large in their treatment of phthisis it is difficult to determine, though they ought never to be lost sight of: yet the ge- neral intentions by which they seem to have been guided, in the * Sur les Maladies Veneriennes, la Rage, et la Phthisie, 12.

To take off inflammatory action. II. To correct the specific acrimony. III. To support under debility. IV. To subdue the local irritation and improve the secretion. V. To excite a change of action. I. If the patient be of a robust habit and in the prime and vigour of life, and if the symptoms indicate considerable inflammation, whether in the lungs or bronchia?, such as, in the former case, fixed pain and weight in the chest, increased by lying one side, with a dry but troublesome cough ; and in the latter, a general soreness rather than pain in the chest, frequent and violent cough with a copious excretion of a thin, offensive, and purulent mucus ; and, in both cases, with a full and strong pulse, the fever, though remissive, making an approach towards a cauma, constituting the plethoric species of M. Portal, and the inflammatory of Dr. Rush, there can be no question that our object in both these cases should be to di- minish the vascular action by every mean in our power. Copious bleeding by venesection should be had recourse to with all speed: and though we shall seldom be called upon so closely to follow the steps of Dr. Dover as to repeat the operation fifty times in succes- sion* before we desist, it may be necessary to follow it up rapidly to the third, fourth, or fifth time, M. Portal, in the catarrhal varie- ty, bled a man, seventy-eight years old, three times with the happi- est effect. Immediately after the use of the lancet, we should em- ploy small doses of ipecacuan or antimonial powder, so as to main- tain a nausea till the pulse is lowered. Where the symptoms approach to peripneumony, the latter is to be preferred; where they lean to an inflammation of the mucous membrane of the bron- chia? the former, of which three or four grains may be given three or four times a-day, and will often prove expectorant, and unload the muscous pellicles of the air-cells. The bowels should, in the mean time, be thoroughly opened by neutral salts or uniting three or four grains of calomel with the nauseating powder: and after this the fox-glove may be had recourse to with a considerable pro- mise of success. Von Helmont first employed this last medicine as a specific for scrophula : but the only specific influence we know it to possess is on the kidneys, and on the action of the heart and arteries. It is for this last effect we look to it in the present in- stance ; the only effect in all probability that renders it of any ad- vantage i.n consumption. In catarrhal phthisis it seems sometimes, however, to improve the character of the exspuition, and to render it less thin and acrid : but this is, perhaps, a collateral result of the diminished action of the arterial system : for an increased flow of genuine mucus, like that of genuine pus, depends upon only a small ^Ancient Physician's Legacy to his Country, 8vo. Lond. GE. III.-SP. IV.] SANGUINEOUS FUNCTION. 50VJ augmentation of vascular energy : since, if the vessels be urged be- yond this, the secretion is hot, watery and acrimonious. If sudorifics be ever advisable in any modification of phthisis, it is here we may expect to find them of use. Bennet indulged the hectic morning sweats as a mean of abating the symptoms, and Morton observes that nothing is gained by checking them: Jiut it is perfectly clear that they very greatly add to the debility, and never prove critical. It has been proposed by others, however, to overcome the morbid sweats by exciting a sweat of a different kind : " for it is as practicable," says Mr. Watt, " to cure sweating by sudorifics, as diarrhoea by cathartics."* There is something plausible in this remark, and the experiment might, perhaps, be allowed to form a part of the reducent plan before us. But the au- thor has never tried it, and even in the state of the disease we are now contemplating, he would prefer mild diaphoretics or relaxants to drastic sudorifics. When a sufficient inroad has thus been made upon the inflamma- tory diathesis, we may content ourselves with an administration of the cooling neutrals, of which nitre is one of the best. It may be given in almond emulsion in the proportion of a scruple to half a pint; and, if the cough be still troublesome, may be conveniently united with some light narcotic, as the extract of hyoscyamus or white-poppy. The diet and general regimen are points of great im- portance ; but upon these we shall have to speak presently. It is not often, however, that phthisis commences with the inflam- matory action we have thus far contemplated.!' Its ordinary march is unostentatious and insiduous; and it takes possession of the fair and delicate, rather than of the firm and athletic frame, and chiefly in those possessing this figure who can trace it in their ancestors and have hence reason to apprehend an hereditary taint. II. Of the proximate cause of this predisponent diathesis we know nothing: it is generally supposed to have a near analogy to that of scrophula; and when called into action it commonly shows itself in the form of the tubercular variety: the tubercles themselves, though not occurring in a structure strictly glandular, bearing a con- siderable resemblance to scrophulous indurations. And, on this account, as there are various medicines, and a particular regimen that seems to have a beneficial effect upon a scrophulous habit, the same have been often resorted to for the cure of consumption. Thus, sea-water, the alkalies, almost all the metallic salts, and es- pecially those of mercury, have been repeatedly tried, but apparent- ly with very doubtful success. Mr. Spalding, in the American Medi- cal Repository, gives the case of a patient who had taken nearly two pounds of potash and soda, intermixed like common salt with his ordinary food, and, he states, with considerable benefit after fox- glove, sulphuric acid and bitters had been successively found to disa- * Cases of Diabetes, Consumption, &c. 8vo.

IV. gree ;* and Dr. Trotter affirms that among seamen in scrophulous consumption, as he calls the tubercular, salt and salt diet have proved of eminent service, but that the most effectual remedy is cinchona with sulphur.! Yet, however serviceable such medicines may have been found in the particular cases recorded, they have not succeeded in ordi- nary practice. " In scrophula," says Dr. Cullen, " the remedies that are seemingly of most power are sea-water and certain mineral waters, but these have generally proved hurtful in the case of tuber- cles of the lungs. I have known," he adds, "several instances of mercury very fully employed for certain diseases in persons who were supposed at the time to have tubercles formed, or forming in their lungs : but though the mercury proved a cure for those other disease5, it was of no service in preventing phthisis, and in some cases seemed to hurry it on."j Nor have any other metallic salts been of more use than those of mercury. Dr. Roberts has had the spirit and perseverance to run through the whole range of such of them as can in any way be thought applicable to this complaint; and has also had the candour, after a sufficient scale of trial in St. Bartholomew's, a candour how seldom to be met with, to confess that none of them were adminis- tered with success. The experimented list consisted of silver in its nitrate ; lead in its superacetate, combined with opium for counter- acting its deleterious effects; zinc, in its sulphate and oxyde ; and the precipitate from the sulphate of potash, combined with myrrh; arsenic in the neutral salt formed by a combination with potash ; manganese in its white oxyde, in doses of ten grains every six hours; cobalt in its black oxyde, in doses of from one grain to four; am- nioniated copper; and muriate of barytes. And with a like want of success, he tells us in addition, were employed the vegetable narco- t tics, aconite, hyoscyamus, stramonium, belladonna, as also toxicoden- dron. || We may hence, I think, fairly conclude with Dr. Cullen that, " the analogy of scrophula gives no assistance in this matter."§ This part of our subject, however, ought not to be closed without briefly adverting to the practice which has lately been adopted by some pathologists, of giving very small doses of antimony in the form of tartar emetic dissolved in a large body of some simple men- struum and continuing it for an almost indefinite period of time : but whether this be recommended with a view of destroying any specific acrimony, or of allaying general irritation, I cannot deter- mine. Dr. Balfour dissolves two grains of the emetic tartar in six ounces of water, and prescribes an ounce of this mixture, that is, a * Vol. v. p. 220. t Medicina Nautica. Vol. III. p. 359.

IV.] SANGUINEOUS FUNCTION. 511 third part of a grain of the tartarized antimony, to be taken every hour, and a smaller quantity where this is found to nauseate. M. Lenthois, in his Methode Preservatif, apparently with a view of im- itating the great processes of nature in her manufacture of those me- tallic and other mineral waters which have been taken with most success, gives it in a far more divided state, and consequently with a much larger quantity of menstruum. He first dissolves a grain of tartarized antimony in eight table spoonfuls of distilled water, and then adds to the entire mixture six or eight pints of water in addition, and sometimes not less than twelve. The solution thus weakened is employed by the patient for common drink in every case and stage of consumption, either alone or with some other drink at meals, or occasionally with wine ; it is taken without limitation at all sea- sons and hours. How far this method may answer I cannot say from personal practice : but the success of M. Lenthois in rendered suspicious from its pretended extent; for he hereby prevents the disease, as he tells us, if it be not begun, and cures three out of four where it is. III. But though in consumptions we can avail ourselves but little of the treatment that applies to scrophula, and know nothing what- ever of the nature of its specific acrimony or miasm, we see enough to convince us that consumption, in its general character is, like scrophula, a disease of debility: and that wherever it exhibits an excess of vascular action, it is merely in consequence of being plant- ed upon a plethoric or entonic temperament. And hence another principle, conspicuous in most of the remedial plans to which it has given birth, is that of supporting the system while labouring under its influence. This principle is well founded but of difficult application; and, like the opposite principle of reduction, has been often carried to an extreme. In its ordinary course, the disease is not only pecu- liarly prodigal of animal strength, but peculiarly protracted in its duration, while the fever, though remissive, rarely subsides alto- gether, or allows any interval of which we can avail ourselves. In some instances, however, it does allow such interval, and espe- cially where it has continued for a long period, and has broken down the general vigour of the frame; in which case Moreton occa- sionally found the inflammatory form with which it commenced con- verted into a low intermittent, sometimes assuming the quotidian, but more generally the tertian type ; beginning with cold fits, and suc- ceeded by intense heat and profuse sweats which exhausted the patient, though they left him in high spirits during the inter- missions.* And in such cases, it is possible that the tonic and stimu- lant plan of bark, wine, and even high-seasoned dishes, with cold air, cold bathing, and active exercise, so warmly eulogized by many writers, may occasionally prove successful, and particularly where the disease is of the apostematous or catarrhal variety, and there is no constitutional taint to oppose at the same time. * See Epanetus Hectica. Vol. u. p. 115. 512 ILEMATICA. [CL. II1.-0R. IV. But this is a plan which cannot be brought into general practice; and, in supporting the strength of the system, we are ordinarily compelled to pursue a very different course. The first means by which we are to aim at accomplishing this is of a negative kind; and consists in saving the frame as much as pos- sible from the profuse exhaustion it is daily sustaining, by calming the febrile irritation, and checking the colliquative sweats, which, as already observed, are never of a critical kind. " I have sometimes succeeded very decidedly," says Dr. Young in a note to the author, while the present sheet was printing, " in checking the sweats by Dover's powder: but I do not know that the progress of the disease has been much retarded by this pallia- tion " Bleeding, however plausible, and even advantageous when the pulse is full and strong, and the pain in the side acute, can rarely be allowed when the frame is delicate and irritable, and the pulse small and weak. Where the local distress is considerable, it may be had recourse to as a palliative, but never carried beyond a few ounces, nor repeated without great hesitation. To emetics there is less objection, but vomiting is here to be preferred to nauseating. The latter, though it lowers the pulse, produces considerable fatigue and distress. The former emulges the bronchial glands, and diminishes the local irritation by transfer- ring it through the means of a general glow and moisture over the system at large. The dose may be repeated three or four times a week, and should have its power limited as nearly as may be to a single inversion of the stomach. In the selection of emetics some judgment is required, for those should be carefully avoided, which, like the antimonial prepara- tions, produce loose evacuations, and excite considerable sweating. The ipecacuan is perhaps one of the simplest and the best. Dr. Simmons, however preferred the sulphate of copper, giving first of all half a pint of water to the patient, and then the blue vitriol from two grains to twenty, according to his age and strength, dis- solved in an additional cup-full of water. In general, he found that the moment the emetic reached the stomach it was thrown up again, upon which the patient was ordered to swallow another half pint of water : which was sufficient to take off the nausea.* The reason that prohibits nauseating, prohibits also the use of fox-glove : for, though the pulse may be diminished, nothing more is obtained, and even this is obtained at too great an expense of sensorial power in the degree of debility we are now contemplating: and the remark will apply to most of the narcotics, whether of the umbellate or solanaceous orders. The neutral salts answer better, and especially nitre; and there is no modification of the disease in which this may not be given, and will not prove an excellent re- frigerant as well as sedative. The general error, however, has * Practical Observations on the Treatment of Consumption, &c. GE. III.-SP. 1V.1 SANGUINEOUS FUNCTION. 513 been in administering it too freely, as in doses of fifteen grains or a scruple; in which case, it becomes a direct irritant, and does much more harm than good. Seven or eight grains at a time, as already prescribed, is a far better proportion, and even in this quantity it will answer best if considerably diluted. It is often united with narcotics; but these are never found of use unless to palliate the cough or local distress; for otherwise they increase the heat, and quicken the pulse. Most of the acids may also be employed for the same purpose, and with equally good effect They may, indeed, be regarded in the joint character of sedatives, refrigerants, and astringent tonics; and have hence every claim to attention. The mineral have been most commonly in use ; but, from their erosive quality, they cannot be thrown in sufficient abundance into the circulating fluids: and on this account the vegetable are to be preferred; and, of the vege- table, the fermented acids, which, though somewhat less grateful than the native, seem to be more effectual as tonics. The acetous acid v\as employed freely by Galen, diluted with water, who re- garded it as the best refrigerant we can select. It is continued to the present day among the Moorish physicians at Tunis, and, ac- cording to the late M. Orban, with decided success. He observed its effects, during three months, upon one patient who appeared to be labouring under a confirmed phthisis from a neglected catarrh. The quantity of vinegar drunk in the course of every twenty-four hours was seven fluid-ounces intermixed with seven times as much rain-water, and sweetened with two ounces of refined sugar. This apozem was accompanied with astringent and tonic pills composed chiefly of alum and sulphate of iron, of each of which two grains and a half were taken daily. The diet allowed was very slender, and consisted of nothing more than vermicelli or millet, boiled in water, and seasoned with a little oil and salt. Of this, only two meals in the four and twenty hours were allowed for several weeks. And, on the patient's becoming very costive under its use, the Moorish physician paid no attention to the symptom, but told M. Orban, that a constipated state of the bowels was the best symptom that could occur, and that the more strikingly this prevailed the more certain he was of a cure. M. Orban left this patient in a fctate of convalescence bordering on perfect health ; and, on his return to France, pursued the same plan, with the exception of the ironj which he omitted as too stimulant, and found it, in many cases, eminently successful, though not in all.* It has since been tried in our own country and has often proved equally advantageous. Dr. Roberts has paid particular attention to its effects ; and, upon a pretty extensive scale, has been satisfied with them. One of hi9 cases was of a very unpromising aspect; and consisted of a voung gentleman, seventeen years of age, whose elder brother had died ef phthisis two years before. The cough, which, in the morning * Med. Trans. Vol. V. Art. xvin VOL. II. 6t> o 14 H/EMATICA. [CL. I1I.-OR. IV. was very considerable, was accompanied with expectoration some- times streaked with blood; a confirmed hectic preyed upon him and the night sweat was so profuse that his hair was drenched with it. « Mv patient," says Dr. Roberts, '■ was at once relieved by the use of the acid, and, in a short time, so lost his complaints, that, by my advice, he discontinued the remedy/'* The acetic and acetous acid seem to have been employed indiscriminately ; over which the citric, which was also tried, did not seem to have any advantage. The acetous was usually given in half ounce doses with an ounce of infusion of cascarilla, and a little mucilaginous powder or syrup, the dose being repeated three or four times a day. From these facts, as well as from a host of others of the same kind that might be adduced, the acetous acid appears to be a power- ful sedative. It diminishes action generally, checks night sweats, restrains haemoptysis, retards the pulse, and produces costiveness. It becomes, hence, necessarily a refrigerant; and it is probable that its refrigerant depends entirely upon its sedative power. That itis also an active astringent is known to every one ; but this seems to be a distinct quality ; for simple astringents, as bistort and catechu, have no pretensions to be sedative ; and the metallic salts, with the exception of those of lead, are directly stimulant. On account of this sedative quality, vinegar, when drunk in abundance, where there is no morbid excitement to suppress, becomes often highly mischievous : for, by unduly taking off the action of the assimi- lating powers, it prevents the secretion both of flesh and animal oil, and hence produces emaciation or a slender form ; and is at times expressly resorted to for this very purpose by young and thought- less females who are afraid of becoming too corpulent. This effect also is often ascribed to its astringent quality, yet improperly ; for it is the character of astringents to increase the solid contents of the frame, and give breadth as well as firmness to the muscles. In haemoptysis, I have carried the use of acetous acid much farther than was prescribed by Dr. Roberts, and with manifest and unmixed advantage. The proper astringents have also not unfrequently been employ- ed in phthisis for the same negative purpose of producing strength by checking the exhausting discharges of sweat, pus, or mucus, blood, and often diarrhoea; but they have rarely proved successful. Some degree of benefit seems occasionally to have been derived from the use of oak-bark, several of the agarics! given in the torm of lozenges, and the superacetate of lead ;\ but they have far more generally been employed without success or with more mischief than advantage. The most direct means of supporting the system would be by * Med. Trans, ut supra. t De Haen, Rat. Med. Tom. n. 567. Dufresnoy, in Corvisart, Journ. Med. Cent. vn. 531. 1804. X Ewell in S.'-dile.

IV.] SANGUINEOUS FUNCTION. 515 those tonics that unite an astringent with a bitter principle ; but we have already observed that the system is usually, and particularly in the beginning and at the height of the disease, in too high a de- gree of irritation for a convenient use of any medicines of this kind : though where the complaint has lasted for many months, and appears to he rather of the tubercular, or catarrhal, than of the apostematous variety, these may sometimes be employed with great success. The Angustura bark generally agrees better than the cinchona, and to this myrrh and iron may at such times be added in increasing doses, and particularly as prepared in the mistura ferri composita of the London College. In the tubercular variety, the cinchona seldom agrees in any stage : Dr. Cullen conceives never; and tells us that even where the disease has assumed something of an intermitent character, quotidian or tertian, and he has, on this account been tempted to try it in free doses, he has in no instances succeeded so as to establish a complete cure. •k for in spite," says he, " of large exhibitions of the bark, the paroxysms in less than a fortnight or three weeks after they had been stopped, always returned, and with greater violence, and proved fatal. In the latter stages of the apos- tematous variety, and especially when the vomica? are small and in perpetual succession, he thinks, however, it may be of service, in restoring a healthy action, and promoting a secretion of genuine pus. In this last case, and here perhaps only, we may venture with success on the use of the cold bath. In a more irritable state or stage of the complaint, the tepid bath may occasionably prove ser- viceable ; and, where it does so, should be repeated three or four times a week, or even oftener. Of the effect of the banos de tierra of the once celebrated Solano de Luque I cannot speak from per- sonal knowledge. It consists in burying the patient up to the chin in fresh mould. It would be most obvious to suppose that this was designed to act as a tonic, and check the undue tendency to perspi- ration by a protracted chill, but that Van Swieten tells us the smell of fresh earth is serviceable, and approves of it on this account. It has since been recommended by Dr. Simmons and M. Ponteau. Before, however, the hectic, or the general irritability of the system has so far subsided as to render tonics adviseable, our chief dependence for giving support to the system must be upon diet and regimen. The diet should be of the lightest kinds, and in very small pro- portion, or with long intervals of rest; for some degree of exacer- bation, in the stage of the disease we are now contemplating, is al- ways produced by the process of digestion. Under limosis expers we have already seen how very small a portion of food is necessary for the support of life, when neither mental nor muscular exercise are made use of; and, though hectic fever itself is a source of very great exhaustion, this exhaustion will be less in proportion as we produce less excitement, whether from eating or any other cause. And hence the mo«t cautious phvsicians. from the time of the Greeks die 1LBMATICA. [CL. III.-OR. IV, to our own day, have concurred in recommending food in small quantity as well as of the lightest materials. It is not merely the stomach and its colhtitious organs that are hereby put at rest, but the circulating system, the assimilating powers, the brain, and the intestines. And hence there was much judgment in the remark of the Moorish physician to M. Orban in the case just adverted to, in which the diet was peculiarly reduced and slender, that costiveness, so far from being an evil, was one of the most promising symptoms that could occur, and which rarely required any attention. It gives proof in reality, that the secernents of the larger intestines are quiescent, that the lacteals have absorbed nearly the whole of the materials introduced into the stomach, and that there is scarcely any refuse matter to irritate afterwards, or be carried off in the form of feces. The food itself should consist principally of milk and the farina- ceous parts of plants, if it be not limited entirely to these: and up- on a diet of this kind, in conjunction with temperate air and exer- cise, the Greek; physicians placed their only hopes of a cure. Wheth- er it be necessary to pay that strict attention to the different kinds of milk which we find in many writers of established reputation I cannot fully determine. Galen recommends woman's milk, as lightest of all, then ass's, next goat's or ewe's, and lastly cow's ;* and Van Swieten adopts the recommendation of Galen.! Mare's milk has since been proposed as preferable to all these : but the analyses published by different chemists vary so much from each other, that it is difficult to come to a conclusion. If the experi- ments of Stipriaan may be depended upon, mare's milk contains most sugar and least cream, butter or caseous matter; and woman's nvtk moct sugar and least butter and caseous matter next to mare's, w.th most cream next to sheep's.J Whence mare's milk should be the lightest of the whole, but less nutritive than woman's. Accord- ing to Parmentier, however, ass's milk contains a less proportion of caseous matter than any of the rest. Peculiar properties may sometimes be given to milk by the food fed upon ; and hence Galen endeavoured to render it more astrin- gent by placing the animal, that was to furnish it, in pasturage, en- riched for the purpose with agrostis, lotus, polygonum, and melys- sophyHum. And as the patient became convalescent, and could bear a richer nutriment, he was allowed to sail down the Tiber and use the cow's milk of Stabiae, which was peculiarly celebrated for its excellence.

Four ounces of this are usually taken morning and evening with an equal quantity of fresh milk from the cow.* The chief foods which have been allowed in the general treat- ment of consumption in its earlier and middle stages, in conjunction with milk and the farinacea, are the vegetable and animal mucilages, but particularly the former. And of these, that obtained from the Iceland liverwort, has been held, and deservedly so, in the highest degree of estimation; for to an aliment of sufficient aourishmmt it adds a tonic power by its bitterness; yet a power that so far from increasing vascular action seems rather to quiet it; as though the bitter principle were itself in possession of something of the seda- tive quality of the hop, Ignatius's bear, or some other plant that decisively unites the two. Were it not, however, that every thing seems to be valued in proportion to the distance of its growth and the difficulty and ex- pense of acquiring it, it would not be necessary for us to go the Arctic circle in quest of Liverworts, as there are several species indigenous to our own country that have all the good qualities of that of Iceland, and in an equal degree: particularly the lichen cocciferus or pyxidatus, commonly known by the name of cup-moss. This was long ago recommended in hooping-cough by Willis; as it has since been employed in hectic affections by Strack ; and by Van Woensel in both phthisis and hooping-cough, and apparently with considerable success.! The lichen pidmonarius, lungwort or lung- moss, common to most parts of Europe, and our own country among the rest, has also occasionally been made use of for the same pur- poses. It is, however, less mucilaginous than several other spe- cies, and so bitter as to be disagreeable to the palate, and in some places, and especially in the Siberian variety, to be employed as a substitute for hops. It requires on this account a longer maceration in water for extracting the bitter principle before it is used. In supporting or recruiting the strength, a due attention to air and exercise is also of high importance. The advantages offered by the first are those of a mild, dry, and equable atmosphere ; and probably these are the whole. If the patient's own country give him these, he need not wander from home. If it do not he must create an artificial atmosphere in his own chamber, or set of cham- bers, by keeping the thermometer at from 60° to 65° of L< arenheit, and confining himself, to this temperature; or he must seek the atmosphere he stands in need of in a foreign climate. The disad- vantage of the former is that though be may support the requisite temperature, he cannot conveniently obtain a sufficient change of * Med. Trans.

IV. uir, nor so well avail himself of the various exercises that might be useful to him, as if he were at liberty to go abroad. Hence a change of abode has been recommended in all ages to those whose native soil is subject to considerable and sudden atmos- pherical variations, though pathologists have by no means agreed upon a meteorological standard. For the patient's residence in our own country, the south-western boundary of the Cornish coast, and particularly Penzance, seems to offer the best asylum ; and where a foreign climate is recommended it should lie between thirty and forty degrees of latitude ; if lower than this, the disease, and es- pecially where ulceration has taken place, seems to be exacerbated instead of diminished; and consequently its fatal issue to be quick- ened ;* notwithstanding that to the natives consumption is little known within the tropics. Generally speaking, a change of climate or of local situation has been determined upon too late ; and hence has not been attended with all the benefit that might otherwise have been reasonably hoped for. On which account, many pathologists have considered it as of little importance, if not more injurious than staying at home, though the most celebrated spots should be selected. Thus Dr. Carmichael Smyth asserts that Madeira is unfavourable to the consumptive when the lungs are materially injured, notwith- standing the mildness and equability of its climate.! Nice and Na- ples are said to be equally unfriendly from the neighbourhood of mountains; and Dr.JSouthey's inquiry has led him to conclude that in Malta, Sicily, and other islands in the Mediterranean, phthisis, though a rare disease among the natives, does not appear to be re- tarded in those who visit them for a cure-! M. Portal dissuades from all such trials by affirming that there is no dependence to be placed upon them, since he has seen the disease accelerated in Eng- lishmen, or those of other northern nations, by a visit in quest of milder air to the south of France; whilst in the natives of Langue- doc or Provence it has been restrained by a removal to Paris.6 The whole of this, however, only shows us that very great care is necessary in determining concerning the state and stage of the disease, the patient's constitution, and the local features of the situa- tion that may be proposed for his residence. Where, in the com- mencement of the disease, there is great irritability, or an inflam- matory diathesis ; or in its advance the strength of the constitution is greatly reduced; and especially where an obstinate diarrhoea has supervened, the fatigues of journeying and of a sea-voyage, and the necessary relinquishment of many of those minuter, but still import- ant conveniences, to which the patient has been accustomed at Sir G.

The topography of the situation about to be chosen is of equal importance ; for if it be strongly marked by lofty cliffs or mountains, the air will seldom circulate freely, but rush in currents in some parts, and be obstructed and become stagnant in others. Such is the state of Hastings on the Sussex coast of our own country, which would otherwise form an excellent asylum for those who are subject to pulmonary affections, and cannot remove far from their native abodes. The shore is skirted by two enormous cliffs of sand- stone that rise between two and three hundred feet in perpendicu- lar height. The old town is built in a deep ravine opening towards the north-east, that lies between them, and the new town imme- diately under the cliffs, fronting south and west: and hence, while the air is rushing in a perpetual current through the former, it becomes stagnant, heated and suffocative in the latter. On this ac- count, it has uniformly been found that small islands without any great boldness of feature, enjoy the most equable temperature, and, when within the range already pointed out, form the most favoura- ble situations for consumptive cases. Madeira is, upon the whole, the best foreign station in the winter season; but from its mountain- ous face, catarrhal affections, and even genuine consumption itself, are, according to Dr. Gourlay, not uncommon to the natives; and in removing to it, therefore, it will be necessary to select a spot of sufficient elevation, and equally sheltered from the meteorological evils of currents, tempests, and suffocative heat. For the reasons just stated, the most equable of all temperatures is that of the sea itself: and hence many patients, who feel incon- venience from a residence on the sea-side, are almost instantly re- lieved by sailing at a few miles distance from it. This has often been resolved into the exercise of sailing, or the sea-sickness which in many instances is hereby excited. It is, nevertheless, a distinct advantage from either, and resolvable into the explanation just stated. Sea-sickness, however, is of unquestionable service in many cases: and particularly in those in which a protracted nausea by other means has already been recommended. The exercise of sailing is useful on another and a very different account. All motion without exertion, or with no more exertion than gives a pleasurable feeling to the system, which the Greeks expressed by the term aeora, in- stead of exhausting, tranquillizes, and proves sedative. It retards the pulse, calms the irregularities of the heart, produces sleep, and even costiveness. Hence sailing on the Tiber was a common pre- scription among the Roman physicians; and many consumptive pa- tients have found great benefit from long voyages, in which they have suffered no sea-sickness, and have been exposed to many varie- ties of atmospherical temperature. Hence, too, the well known ad- vantage of exercise in a swing, or in a carriage, on horseback, or even on foot, as soon as these can be engaged in with comfort: thr 520 HEMATIC A. [CL. IU.-OR. IV. organs of respiration, like those of every other kind, deriving strength, instead of weakness, from a temperate use of them. Gymnastic medicine, however, seems by many pathologists to have been carried to an extreme; and especially by Sydenham, who employed horse-exercise in all stages of the disease, and roundly affirms that neither mercury in syphilis, nor bark in intermittents, is more effectual than riding in consumptions.* Nor is carriage- exercise, says he, by any means to be despised though not equal to that of the saddle. Hoffman, and Baglivi adopted the same opinion, and laid it down in terms nearly as unqualified. Where phthisis is a secondary disease, and dependent upon some obstruction of the digestive viscera, exercise of this kind may, in many instances, be employed as an important co-operation with other means even from ths beginning; and to such cases of consumption Desault judicious- ly limits it. In the present day it has been revived by Mr. Stewart uider a variety of ingenious modifications, and appears in many eu.-^s to have afforded relief: but the constitutions of mankind must strm^elv have altered since the days of Sydenham, if the severity of horse exercise could as that period have been employed as a specific remedy in consumptions of every kind. Stoll did not find it -o in the middle of the last century ; for he tells us that if a con- sumptive patient mount his horse he will ride to the banks of the Styx is surely as if he were in a pleurisy. And Stoerck died con- sumptive though in the habit of riding, killed by an haemoptysis ap- parently produced by this exercise.J IV. Another part of the curative process in the disease before us, has consisted in endeavouring to subdue the local irritation, and im- prove the secretion from the lungs. This has been chiefly attemp- ted by fumigations, medicated airs, and expectorants. Bennet was strongly attached to the first of these, and thought they proved peculiarly detergent, and enabled the patient to throw up a more laudable discharge with increased facility. He some- times employed aromatic herbs which were immersed in hot water, over which the patient held his head surrounded with clothes to confine the vapour, which was thus inhaled with every inspiration. But he seems to have placed more dependance on an inhalation of the fumes of various terebinthinate resins, as frankincence, styrax, and turpentine itself, mixed into a powder or troche with a few other ingredients, and burnt on coals: to which he sometimes added a considerable proportion of orpiment. And such was the success ascribed to this practice, that Willis, not many years after, resolved the greater exemption of certain parts of England and Holland, from coughs and consumptions, to the turf and peat fires which the in- habitants were in the habit of using, and the arsenical principle which was intermixed with the material. In our own day, terebin- * Opp. p. 629. t Nat. Med. i. t Quarin, pp. 168, 103 6E. I1I.-9P. IV.] SANGUINEOUS FUNCTION. tbinate fumigations have been very extensively tried in consequence of the warm recommendation of Dr. now Sir Alexander Crichton, who thought he had perceived great and decisive advantage from the aroma of pitch and tar diffused through rope manufactories, ships, and other places where these articles are in perpetual use. I have tried this repeatedly by heating a tin vessel of tar over an oil or spirit lamp, and thus impregnating the atmosphere of the chamber with the powerful vapour that arises. In doing this, how- ever, we must be careful not to burn the tar; for in such case the room will be filled with an empyreumatic smoke that will greatly add to the patient's cough instead of diminishing it. In those states of the disease in which terebinthinates, as myrrh., benzoin, or co- paiba, may be taken internally with a prospect of success, this kind of fumigation will sometimes prove useful also: and it is hence far better adapted to the tubercular and catarrhal than to the aposte- matous variety. In a chronic state of both the first, I have some- times thought it serviceable ; but I have more frequently used it without any avail. Pneumatic medicine, which, about thirty years ago, was in the highest popularity, does not appear, when candidly examined, to have been more successful. Oxygene gas has, in almost every in- stance, proved so stimulant, and so much increased the signs of in-< flammatory action, that though it has seemed occasionally to afford a momentary relief in a few cases, it has rarely been persevered in more than a fortnight, by which time it has often suppressed the usual expectoration, and produced an haemoptysis.* There was much more reason and ingenuity in recommending an inhalation of hydrogene intermixed with common air than of oxy- gene : since the effect of this gass in destroying the irritability of the living fibre is known to every one; and it was hence a plausible conjecture that by being applied immediately to the seat of disease it might sufficiently subdue the inflammatory impetus, change the action of the ulcerated surface, improve the secretion, and annihi- late the hectic. The experiment has been tried at home and abroad upon a pretty extensive scale, by employing different proportions of hydrogene, so that the patient has twice a-day breathed from a pint to a quart of the gass at a time, diluted with from twelve to six times its measure of common air; and making every allowance for an exaggeration of statement in those who have most warmly en- gaged in the practice, it seems difficult not to concede that it has proved serviceable in various cases. A combination of hydrogene with common air seems, indeed, to be beneficial in various other modes of application; but whether by lowering the ordinary stimulus of common air or by directly decom- posing and exhausting the nervous fluid communicated to the lungs it is not easy to determine. In either way, however, it has an equal tendency to indispose them to inflammatory action. Thus Clapier, * Fourcroy, Annales Chirur. I v. p. 83. 1790. VOL. II. 6G 521 r)22 -HjEMATICA. [CL. IH.-OR. IV. in the Journal de Medicine, relates a case of confirmed consumption r.nred by an habitual residence in a coal-mine;* and expressly states that the matter expectorated soon began to assume a more healthy appearance, and was excreted more freely. It is, in like manner, a common remark that the miners in Cornwall are more generally exempt from phthisis than most other persons:! and that butchers, who are perpetually engaged in slaughter-houses, and surrounded by a vapour impregnated with hydrogene, possess an equal emanci- pation. It is probably to this cause, if to any, we are to ascribe the benefit which Bergius found consumptive patients derive from a re- sidence in cow-houses,! and which was not long since a fashionable mode of practice in our own country. Expectorants and demulcents have, also, very generally been em- ployed for the same purpo=e; that of subduing the disease by ex- citing a healing action in the tubercles or ulcerations, indicated by an improvement in the expuition. Of the general nature and mode of action of these classes of medi- cines, we have already spoken at large in discussing the treatment of cough and asthma :§ and our remarks, therefore, upon the present occasion will be but few. Where the irritation is considerable, and accompanied with much increase cf vascular action as in the commencement of the aposte- matous and catarrhal varieties, the best demulcents, and, indeed, the only medicines of this kind we can employ as palliatives, are the vegetable mucilages, as of tragacanth, quince seeds or gum Arabic. Where it is necessary to diminish the general action, these may be united with small doses of ipecacuan, or of squills; which have the double power of exciting nausea, and unloading the mu- cous follicles of the bronchiae as expectorants. And, where the cough is very troublesome, and the pain acute, they should be uni- ted with narcotics, as opium or hyoscyamus.' In a more advanced stage of the disease, and through the entire course of the tubercular variety, except where haemoptysis is present, the expectorants more properly so called have often been employed with advantage. One of the oldest of these is sulphur, and perhaps one of the best; from its not readily dissolving in the first passages, it i? carried to the rectum, and the skin sometimes, with little alte- ration ; and hence gently stimulates both extremities, loosens the boweK and excites a pleasing diapnoe on the surface. It is in this way it appears to be serviceable in an inflammatory or tubercular state of the lungs. It was in high repute among the Greek and Ro- man physicians, who, when employing it as an expectorant, usually combined ;t with yolk of egg ; and it has maintained its character to the present day. In the tubercular, or scrophulous variety, as it is * Jnu.n. Med. xvm. 59. + Southey, Observations on Pulmonary Consumption, 8vo. 1814. X Ni'up Schwed. Abhandl. 1782. P. in. p. 298.

The vulnerary balsams an.l resins, however, have been more ge- nerally had recourse to; but ought rarely, perhaps never, to be em- ployed in an early stage of the disease. Their action is common, and depends upon their possession of a terebinthinate principle ; and hence they might be used indiscriminately, but that some of them are less stimulant and heating than the rest. Myrrh and camphor are among the least irritant, and may often be employed when we dare not trust to any other. Copaiba, though of somewhat greater balsamic pungency, has often been found essentially useful. Marry- att was peculiarly attached to it: he gave twenty drops of it night and morning upon sugar; and asserts that, when an ulcer has been formed, it ought never to be omitted :J and Dr. Simmonds appears to hold it in nearly as high an estimation.§ V. The last part of the general therapeutic process which has been attempted in most ages, has consisted in endeavouring to dimi- nish or carry off the local affection by a transfer of action. Blisters have very generally been applied for this purpose to the back or the chest. Their service is temporary, but often very ef- ficacious, and they ought never to be neglected. It was formerly the custom to render them perpetual by the use of savine ointment, or some other escharotic. But it is equally less painful and more beneficial to let the skin heal, and renew them after short in- tervals. Setons, issues, and caustics, however, where the constitution is not very delicate, nor the habit very irritable, have proved far more powerful revellent^, on account of their more violent stimulus and greater permanency of action. The actual cautery, though much abstained from in modern practice from its apparent, rather than real severity, was in almost universal use in ancient times; and, in the mode described by Celsus, was undoubtedly a very formidable operation. When the disease, says he, has taken a deep root, the cautery must be applied under the chin, in the throat, twice on each breast, and under the shoulder-blades; and the ulcers must not be healed as long as the cough continues. Dr. Mudge pursued this plan to a very considerable extent on his own person, and ascribes his cure to the use of it. He applied a large caustic between the shoulders, which produced an eschar of nearly three inches in dia- meter, and held fifty peas : but he confined himself at the same time to milk and a vegetable diet.|| Bennet exchanged the caustic for * Medicine Expectante, Tom. ill. p. 237. 8vo.

Yet scions are said by those who have employed them to be still more service- able than issues. , . . , , The obvious intention is to produce a revulsion; and hence by transferring the morbid action to a part of less importance, to allow the lungs to return to a healthy condition. . Such transfer may, by these means, in some cases, be rendered to- tal, though, in general, the morbid irritation is only partially, in- stead of entirely, carried off. There are other means, however, by which it seems to be removed altogether, although they are means that are seldom put into our hands. Thus M: Bayle's fifty-third case is that of a medical man who was fully prepared to meet his fate, and resolved to take no medicine whatever. At this time a severe rigor from an unknown cause at- tacked him, succeeded by a sweating fit so profuse that his linen was changed two-and-twenty times in a night, and even thi* was not sufficient. The paroxysm proved critical; and the disease was thus carried off by an ephemera.* Sir Gilbert Blane gives an account of a like singular and salutary change excited by a hurricane at Barbadoes, in 1780 ; which pro- duced such an effect on the air, or on the nerves of the sick, that some who were labouring under incipient consumption were cured by it; while others, who had reached a more advanced stage, were decidedly relieved, and freed for a time from many of their symptoms.! Bennet relates a case of consumption which was suspended for two days in all its symptoms, except the emaciation, by a severe tooth-ache.J In Hautesierck's collection, we have an account of a recovery from a purulent expectoration, by the formation of a fistu- lous abscess in another part of the body, which was itself cured by an operation.§ And we have numerous instances of consumption produced by a sudden cure of some chronic cutaneous eruption, and especially itch ; and of its ceasing upon a restoration of the pri- mary complaint. There is, however, no affection that seems to keep a consumptive diathesis in so complete a state of subjugation as that of pregnancy. Most practitioners have seen cases in which a female has dropped all the symptoms of phthisis upon conception, and has continued free from the disease till her delivery. Suckling does not seem to continue the truce ; but if she conceive again shortly afterwards, she renews it: and there have been instances, in which from a rapid succession of pregnancies, the suspension has * Kecherches sur la Phthisie, &c. ut supra. t Observations on the Diseases of Seamen, 8vo.

As one disease, therefore, or state of body, is well known to have a frequent influence upon another, and consumption is found to be thus influenced by various affections, it is a question well worth in- quiring into whether there be any malady of less importance, which, like cow-pox over small-pox, by forestalling an influence on the con- stitution, may render it insusceptible of an attack of phthisis > Dr. Wells not many years ago, very ingeniously engaged in an inquiry of this kind ; and finding that it was common for the consumptive in Flanders to remove to the marshy parts of the country where agues were frequent, he began to think, not indeed that agues might give an exemption from consumptions, but that the situation which pro- duced the former might prove a guard against the latter. And so far as his topographical investigations have been carried, and they have extended over some part or other of all the quarters of the globe, this opinion has been countenanced : for he has discovered that wherever intermittents are endemic, consumption is rarely to be met with; while the latter has become frequent in proportion as draining has been introduced.* The later inquiries of Mr. Southey do not support this hypothesis; but the question is yet unsettled, and well worth pursuing; and Mr. Mansford who practices in the in- terior of Somersetshire, has still more lately published a work which, though not written as a defence of Dr. Wells's opinion, in- directly confirms it, by endeavouring to prove that a low, inland situation, like the vales of his own country, are far better calculated as a residence for consumptive patients than the air of mountains or of the sea-coast.!

IV. importing swine-evil, swine-swellings, or morbid tumours to which swine are subject. Celsus employs struma, which was common in his own day, and has well described the complaint under this name, which is therefore selected on the present occasion. It is probably derived from rr^aftx, " congestion," or " coacervation," as of straw in a litter, feathers in a bed, or tumours in the body; in which last sense Cicero elegantly employs the term as a metaphor in the phrase "struma civitatis," "the scrophula or king's-evil of the state." The medical dictionaries and glossaries concur in deriving struma from the Latin struo, but the terminating syllable of the noun should rather prove it to issue from a Greek source. Dr. Stoll endeavoured to make a distinction between scrophula and struma,* by regarding the one as a local, and the other as a con- stitutional and hereditary disease; but although he has been follow- ed by a few writers, as well in our own country as on the conti- nent, it is a distinction which has been generally relinquished as neither useful nor founded in fact Other animals are subject to this disease besides man. It is, as already observed, from the frequency of its appearance among swine that the Greek name, as well as the more recent one of scrophula, is derived. Among horses we meet with it at least as often, when it is called farcy; under which modification it is propagable by trarisfusion of blood from the diseased horse, not only to other horses, but to asses also, as has been lately proved by Professor Coleman, at the Veterinary Institution. Sauvages, who has many species under the generic character, has two for the forms now referred to. The porcine species he denominates scrophula Cha- lasis, and the equine s. Farcimen. As it is not the intention of the present work to notice the dis- eases of other animals, otherwise than by an occasional and inci- dental glance, we shall proceed to a contemplation of the present genus under the single species of 1. struma vulgaris. king's evil. The strumous and mesenteric decline, in the present classification atrophia strumosa, is often introduced as a second species : but though nearly allied to the present genus, it has so much closer a connexion with all the subdivisions of the genus marasmus, and especially with that of atrophia that the former is evidently its proper place ; and we have accordingly treated of it under that genus. In Dr. Cullen's Synopsis, it is arranged under the genus scrophula ; and in defe- rence to his authority it was allotted a like position in the first edition of the Nosology of the present writer : but in the subsequent editions it will be found transferred to the position before us. * Praelect. p. 30.

King's Etofl. tumours confined to the external conglobate glands; PEA-SIZED7 or chesnut-sized ; appearing in infancy or youth ; SUBSIDING ON mature age ; hereditary. Scrophula though not a contagious disease is unquestionably here- ditary :* and hence very generally dependent upon a peculiar diathesis. Yet, like many other hereditary diseases, it is also occa- sionally generated as a primary affection, without any hereditary taint that can be discovered. I have at this moment a gentleman under my care who has been greatly afflicted with it for many years, and is now chiefly labouring under its sequelae : for the sores, which are in different glands and joints, and some of which have affected the bones, are healing: yet of eight brothers and sisters who have reached the middle of life, he is the only one who has discovered any tendency to such complaint, nor is it to be traced through any part of the family lineage as far as it can be ascended. When it occurs as a primary or ingenerated affection it is by no means always limited to any particular temperament or habit of body. The individual just noticed is of moderate stature, brown complexion, dark brown hair, and ruddy face : and I am still occa- sionally attending a lady who has long been subject to the same complaint without any trace of hereditary predisposition, of a sallow countenance, dark eyes and hair, and of rather tall and slender make. But where scrophula appears hereditary, and espe- cially where it does not show itself very early, it is often accom- panied with a peculiar constitution. " It most commonly," says Dr. Cullen, " affects children of soft and flaccid flesh ; of fair hair, and blue eyes; smooth skins, and rosy cheeks; and such children have frequently a tumid upper lip, with a chop in the middle of it; and this tumour is often considerable and extended to the columna nasi, and lower part of the nostrils." And it is a farther remark of Dr. Cullen, but which I have not found to hold very generally, that, where it takes place in children whose parents have given no signs of it, the latter have nevertheless evinced much of the habit and constitution by which the disease is ordinarily characterized. From all this we have a clear proof that king's evil is a disease of debility, operating by a specific influence on the circulating, and * Kirkland, On the Present State of Surgery, Vol. II.

IV. particularly on the lymphatic system.* Whether thi* influence is the result* of a specific matter is by no means so clear; however common the opinion. It is also a general belief that this specific matter is from the first a specific irritant or acrimony. But this at least is a mistake : for the disease is accompanied throughout with diminished, instead of with increased irritability ;! and hence the power producing it must be of a sedative rather than of an exciting or actuating quality. And it is in this diminution of irritability that scrophula differs from all other atonic diseases, since the debility and the irritability generally augment in like proportion, and main- tain an equal march. Early life is peculiarly characterized by an abundance of albumen, as its maturity is by an abundance of fibrin. Dr. Parr ascribes the scrophulous diathesis to a redundancy of albumen at this period, together with an excess of oxygene and a deficiency of azote, evi- denced by the florid hue of the countenance. By this hypothesis he obtains a sort of lentor in the circulating system ; and accounts for the origin of scrophulous tumours by arguing that, since the mobility of the lymphatic system is peculiarly affected and diminish- ed, the viscid fluids will be most disposed to stagnate there, and particularly in the lymphatic glands; as they must necessarily stagnate most where the impelling power is least. Be the proximate cause, however, what it may, as the remote cause is of a debilitating kind, we can readily see what are likely to prove occasional and co-operative causes ; or those calculated to call the remote cause into a state of activity. They must consist of every thing that directly lowers and reduces the tone of the living fibre, and puts the system out of that state of firm and vigorous elasticity which is the best prophylactic against scrophula, and keeps the scrophulous diathesis most effectually in a state of subjection. And hence we find the common debilitating powers of cold, damp, meagre or unwholesome food, want of cleanliness, and a close and suffocating atmosphere, the most usual incidental sources of scrophula. But for these, a scrophulous predisposition might remain dormant in the constitution through the whole of life ; and descend to, and disorder the next generation, without having in the least disturbed the present. But the moment any of these occasional causes become adjuncts with the scrophulous diathesis, scrophula, rather than any other disease they are also calculated to promote, will make its appearance, and commence its ravage. And hence the frequency of this disease in large manufacturing towns, and in higher and colder latitudes than 45°. For the same reason, the disease has, at times, been called into activity by local injuries, the depressing influence of severe grief, on a sudden reverse of worldly prosperity. It is also sometime? * Gain, Krai.ken geschichten. p. 121. t Richter, Chir. Bibl. Band. vm. p. 501. GE. IV.-9P.

But though scrophula usually commences in the lymphatic glands it often extends beyond them: as gout, that ordinarily shows itself at first in the small joints, and rheumatism in the large joints, spread not unfrequently to the membranes and the muscles. I have said that under the influence of the scrophulous diathesis the circulating system is weakened generally; and hence also we frequently find the eyes, the mucous glands of the nose, the tonsils, and even the joints and bones successively yielding to its influence. The disease for the most part shows itself early in life, though rarely before the second, and commonly not till the third, year of infancy ; from which period it continues to prey on the system till the seventh, when, in ordinary cases, it gradually subsides and dis- appears. If the predisposition be not considerable, the attack is sometimes postponed till after the seventh year, and has occasionally been retarded till the age of puberty, after which, however, we have very seldom any manifestation of the disease. The first tumours we meet with are usually upon the sides of the neck, below the ears, or under the chin; confined to the lymphatic glands in these parts, and only spreading to the salivary when the disease has considerably advanced. The tumours are, perhaps, two or three in number, moveable, soft and slightly elastic, of a globular or oval figure, without pain or discolouration of the skin. In this state they continue for a year or two: after which they grow larger, and become more fixed; and acquire a purplish redness. They then give a feeling of greater softness, and at length of fluctuation : after which the skin, in one or more of them, becomes paler, and a peculiar liquid is poured forth at several small aper- tures, apparently like immature pus, but growing daily less puru- lent, and at length assuming a curd-like form. The tumour or cluster of tumours then subsides; but others rise in the neighbour- hood ; and in this manner the disease proceeds, fresh tumours form- ing, chiefly in the course of the spring, as the older disappear, and the same process is continued for several years: after which the ulcers heal spontaneously with puckered and indelible indentations, provided the disease terminates favourably : but if not, other parts of the system, as we have already observed, become tainted with the morbid influence, and add to the sum of distress. If the attack fall upon the eye-lids they become inflamed, are swollen and red, and pour forth, from their minute glands, an erosive but viscid secretion which glues them together at night, so that in the morning they are opened with difficulty. The adnata partakes of the irritation, which is at length communicated to the whole globe of the eye, and not unfrequently to the cheek, from the acrid discharge that flows down. An unsightly lippitude and eversion of the lower eye-lid is hence a very common result of a scrophulous attack on this organ. In like manner the disease, in this unfavourable and aggravated vor.. n. ft 7 530 HiKMATlCA. [CL. III.-OR. IV. state, often makes its assault on the limbs, and fixes on the ligaments, cartilages, or even the bones theniselv-s ; and particularly when- ever anv injury occurs to a joint. An indolent tumour first shows itself which tardily advances in magnitude with a kind of smothered inflammation, and at length opens on the surface from one or more minute ulcerations which discharge the sanious kind of fluid we have already noticed. And it is here we perceive how nearly scrophula is related to hydarthrus or white-swelling; and how readily the former may become a cause of the latter, as already observed under that species. If the strumous diathesis be excited by the fracture of a bone the broken ends unite with great difficulty, and sometimes not at all. A specific tumour forms in the seat of the injury, the soft parts are often affected with a weak inflammation, and ulcerate slowly ; and the bone is rendered carious. If the injury occur in the middle of a cylindrical bone an exfoliation may take place in a long course of time : but if at its extremity, it will become spongy, enlarged, and disorganized. If a cure be at length effected, the enlargement will remain and the articulation be lost: yet amputa- tion will be of no use while the part continues under the influence of the scrophulous taint. In the worst and severest stage of the disease, the entire system appears to be contaminated ; hectic fever ensues, and sometimes tubercular phthisis which gradually puts an end to the contest. In attending to the cure, we must not be unmindful of the princi- ple we have endeavoured to establish that scrophula is a disease of debility principally affecting the lymphatic system, accompanied with diminished irritability. And it hence follows that our chief dependence must be upon a tonic and stimulant plan, so modified as to meet the patient's age, idiosyncrasy, and manner of life. How far an acrimonious principle may be generated, after the disease has become aggravated and general, it is difficult to say r but in its commencement, and while confined to the lymphatic glands, and indeed through the whole of its ordinary and milder course, it induces diminished rather than exalted irritability, and consequently gives no proof of an acuating or acrimonious source, let such a source has been supposed even from its first appearance : and hence sedatives and narcotics have found a place among the most cele- brated of its remedies: while, as the chemical character of the ac- rimony has been also pretended to be developed, and has been de- clared to be a specific acid, another class of remedies had recourse to has been the alkalies. That the latter are often of considerable service ought, I think, freely to be admitted; but we have assuredly no proof that they become beneficial as correctors of acidity. They are gentle stimu- lants admirably adapted to the debilitated and indolent condition of the vascular system they are intended to excite : and hence in what- ever form they are given have a chance of doing good. And it is to this principle we are perhaps to resolve all the advantage that has been stated by different writers, and in different ages of the «^ upon. Where the disease has spread widely or continued long, some of the muscles of respiration participate in the irritation, and the breathing is performed with difficulty. When cancer attacks the uterus it is known by tensive lancinat- ing pains in this organ, shooting through the region of the pelvis ; indurations in the part sensible to the touch; a preceding and im- moderate leucorrhoea, or menstruation ; sometimes both. The ul- cerative process, as far as we are acquainted with it, is the same as already described; and as soon as it has worked to the surface oi the organ, there is a sanious, or bloody, or mixed discharge charac- terized by the peculiar stench of the disease. By degrees, the labia swell and become edematous; and if, as sometimes happens, the inguinal glands be obstructed, the edema extends along the thigh. Cancer in the vagina which, however, rarely takes place, can easily be felt, and in the rectum the distinction is not difficult. The nature of the discharge, and the other symptoms just noticed, are sufficient to decide its existence. It is still more obvious in the penis. None of these symptoms assist us in determining its presence in the stomach : and hence how confidently soever it may be conjec- tured from the marks of an acute and burning pain, tenderness of the epigastrium upon pressure, nausea, and rejection of food, and even an offensive fetor in the breath, the disease can seldom be completely asertained till after death. The progress of cancer in the testicle is often slower than in many other parts. In chimney-sweepers we can trace an obvious cause, which is that of soot lodged in its rugae, and irritating as well from its own acrimony as from that of the perspiratory fluid with which it comes in contact and forms an union. A painful ragged sore with hard rising edges is first produced ; or, sometimes, a little indurated wart; which, from inattention, increases in size, is repeatedly rub- bed off by the exercise of climbing, enlarges and deepens its sphere of irritation, grows more malignant, and at length is converted into a real cancer, and affects the whole scrotum or the body of the testis. In whatever part of this complicated organ, however, the disease commences, it is progressively communicated to the rest; the scir* rhosity increases in size and hardness, till the tumour often acquires an enormous and irregular magnitude, studded externally with nu- merous protuberances, and the shape of the testis, even before ul- ceration, is entirely lost. In the progress of the disease, the sper- matic chord becomes affected, and the taint or irritation is communi- cated more or less to the viscera of the peritoneal or lumbar cavi- ties. From the cancerous effect of a highly irritable wart or crack on the scrotum of chimney-sweepers, we may derive some idea of the formation of cancers on other superficial parts of the body from a similar beginning. These most frequently occur on the lips, nose, or eye-lids ; and oftener from a crack than from a wart. The edges of the sore become hard, and one or more tumours issue from them, which increase in size and gradually evince a cancerous character. 540 ilematica, [cl. hi.-or. iv. On the tongue the same disease sometimes shows itself; and more usually commences with a small wart or pimple near the tip, which hardens by degrees, grows highly irritable and malignant, and, spreading its influence through the entire organs, swells it to a pro- digious size and renders it of a scirrhous induration. Cancer is said, in a few instances, to have terminated spontane- ously. De Haen gives us one example of this :* and Parr affirms that he has seen six cases of the same in his own practice. But he adds, in proof of its being a constitutional affection, that in every case the cure was followed by some other disease, as an enteritis, fixed pains in the limbs, a sciatica, or an apoplexy, in one of these cases the apoplectic attack occurred twice, and the last was fatal.! In general, however, a cure is rarely affected but by the knife or a caustic, the use of which it does not belong to the present course of study to explain. Yet the progress of the complaint may per- haps be arrested; and we are often able, without cutting, to render it, at least tolerable, for a series of years. In an early stage of the disease relief may often be obtained by topical bleeding, as with leeches ; and topical refrigerant applications, as saturnine lotions, or sheet-lead in very thin layers, as the linings of tea-packages, an application which has of late been brought forward as something new, but which was employed long ago, and may be found recom- mended in many of the older journals of established reputation.^ The diet should be limited to the mildest nutriment, and wine he sedulously avoided. At this period, indeed, whatever can prevent or lessen inflammation should be seriously studied, and adhered to. Ponteau relates the case of a cure produced by rigid abstemious- ness alone, the patient taking nothing whatever but water for a period of two months.§ As, however, the disease advances and assumes more of a chronic character, the activity of the smaller vessels may be gently urged in order to relieve or prevent congestion. And, where the irrita- tion is not great, we may by degrees apply gentle stimulants also externally, and let the saturnine lotion be superseded by the acetat- ed solution of ammonia, tar-water as recommended by Quadrio, or an illination of the surrounding parts with mercurial ointment com- bined with a small portion of camphor. The internal medicines which have been chiefly trusted to for the cure of cancer, are the lurid and umbellate narcotics and the mineral tonics: the former apparently for the purpose of taking off irritation, and, in some instances, correcting the specific acrimo- * Epist.

Fothergill is friendly to its use ;* and Bellt and Fearon* recommend it both externally and internally, alone or in combination with opium. For this discrepancy of judgment we have in some measure endea- voured to account. Yet the advocates of the medicine have, doubt- less, in some instances, suffered themselves to speak of it in exag- gerated terms; and it is highly probable that in others, where it has seemed altogether inefficacious, the hemlock, whether in pow- der or extract, was administered in an imperfect state. Dr. Cullen gives a striking example of this last fact in a lady who, being very particular in the use of this medicine, employed the powder as mostly to be depended upon, and weighed out her own doses, begin- ning with a small quantity at a time and proceeding gradually till she took sixty grains at once. By this period her parcel of the powder was exhausted; and she had derived no beneficial effect. She supplied herself, however, with another parcel, and being warned that different samples were rarely of the same strength, she reduced her first dose of the new plant to a scruple: yet even this nearly killed her: for in ten or fifteen minutes she was affected with sickness, tremor, giddiness, delirium and convulsions. Happi- ly the sickness proceeded to a vomiting, and the poison was reject- ed. But of the fresh supply she was never afterwards able to take more than five or six grains at a dose, notwithstanding she had taken sixty grains of the preceding without any mischief.§ Yet the quantities pretended to be given by some practitioners are far beyond this last amount. Thus, Dease informs us that he gave an ounce and a half of the powder every twenty-four hours,[| and performed a cure ; and Rostard that his ordinary allowance was six drachms of the extract for the same period, which is a still high- er proportion.IT Warner gave a drachm and a half, and thought it an enormous quantity, without mischief.** Upon the whole, the balance of experiments seems very much to confirm the candid report of Dr. Akenside. Schaeffer, and many others contend that even its beneficial influence is nothing more than a result of its narcotic power: but it does seem, in some in- stances, to act as a discutient, and to improve the quality of the secretion as well as to relieve the pains. Dr. Cullen advances further, and tells us that he has found it in several cases, make a considera- ble approach towards healing the sore; " Though I must own," * Works, Vol. n. passim. t On Ulcers, Part n.

I.] SANGUINEOUS FUNCTION. 543 says he, " that I was never concerned in a cancerous case, in which the cure of the sore was completed."* Of the other narcotics, chiefly of the solanaceous order, that have been employed, it is hardly worth while to speak particularly. The same uncertainty has accompanied their use : and some of them, as aconite and dulcamara, have been rather supposed to effect what- ever temporary benefit has flowed from their employment by the general disturbance they produce in the system, whereby a transient stop is put to every other anomalous action, than by their sedative power. Of the metallic oxydes that have been brought into use, the only ones itis necessary to notice are those of mercury, iron, and arsenic. The first has been uniformly found mischievous when carried to the extent of salivation. Loss asserts that by this mean he has cured a cancer of the nose and face ;t but this was probably a spurious dis- ease of zaruthan, as it has been called by some writers. It has more generally been employed as a gentle stimulant or alterant. Many practitioners have preferred the corrosive sublimate in small doses; but the submuriate is a far better preparation. And even this is given with more advantage in the form of Plummeris, or the compound calomel pill, than alone, a form that conveniently unites a mild stimulant with a mild relaxant. To this,*if the pain be acute, should be added a small quantity of opium ; at the same time care- fully guarding the bowels against constipation by any convenient aperient, if the pill itself should not prove sufficient. Iron has been tried in almost every state of combination, and there is reason to believe that in some of these it has proved beneficial. The ferrum ammoniatum appears to have been the most successful, and is still the most popular. Under the name of flores marliales it was introduced for this purpose before the public as far back as the middle of last century, by Francis Xavier de Mars, obtained, however, by a very uncouth and operose process. Dr. Denman was particularly attached to this metal in whatever form administer- ed, and broadly affirms that after having employed almost all the medicines recommended for this disease in every different stage, he has never found any of them possess the pretensions of iron ; and that the rest may be generally regarded as totally unavailing.^ Its greatly stimulant power rather recommends it to us on the present occasion than proves an objection ; for it is the kind of stimulus we stand in need of to excite a new local action. It is said to produce a very speedy mitigation of pain, an improved discharge, and a less fetid smell: and, even in hopeless cases, to render the disease less malignant and distressing: unfortunately, however, its effects, like those of conium, have rarely been found permanent; and it has closed its career as a palliative rather than as an antidote. * Mat.

But of all the medicines of this class arsenic has acquired the highest and most extensive reputation. This is a strictly oriental remedy, employed, as we shall have occasion more fully to observe when treating of elephantiasis, for every impurity of the blood. Who first ventured upon it in Europe for the disease before us, is not very satisfactorily known. It was common in the time of Hil- danus who ascribes its introduction into practice by the monk Theo'doric, who flourished about the beginning of the eleventh century* It has formed the basis of almost all the secret remedies for cancer which have at any time been current, whether external or internal, from that of Fuschius, in the fourteenth century, who united it with soot and scrpentary, to that of Richard Guy who wrote upon the disease? in the middle of the last century, and whose boasted arcanum was found to be a composition of arsenic, sulphur, hogsfennel (peucedanum officinale,) and arows's-foot (ranunculus syh:esiris.)l Of the real effects of arsenic, as of several of the preceding medi- cines, we labour under great obscurity from the discrepant reports which have been communicated. Le Febure with a host of practi- tioners antecedent to, and contemporary with himself, employed it both externally and internally, and regarded it as a specific.§ Smalz thinks it serviceable.j| SchneiderlT and Justamond declare it to be useless, though the'latter employed it locally as an escharotic. Hil- danns** and Deliusff assert it to be injurious; and SchenckfJ and Meibom§§ give examples of fatal effects from its employment. Fatal effects, indeed, it is easy to produce, provided a sufficient degree of caution be not employed in experimenting upon it. And, in truth, it is not till lately *hat any very convenient form has been devised for trying its virtues without a risk of mischief; but the arsenical solution of the London College, for which we are indebted to Dr. Fowler, has given us a preparation of this kind. Yet even with this advantage we cannot boast of any certain success in the use of arsenic. It acts very differently on different constitutions, though generally speaking it proves beneficial; and in some cases may produce a radical cure. But more commonly, like the pre- parations of hemlock and iron, it unfortunately loses its effect as- * Cent. vi. Obs. 81. t Essays on Scirrhous Tumours and Cancers. 1759. % Richter, Chir. Bib).

And perhaps the only power that is capable of neutralizing cancer or keeping it permanently in subjection is the existence of a pre- dominant diathesis of some other kind. How far the remark may have been made antecedently I know not, but, from a pretty close attention to the subject within my own sphere of observation, 1 have been led to conclude that cancer does not often make its at- tack upon those who are constitutionally subject to gout, and seems to be restrained by its influence. The list of external applications is still more numerous than that of internal. We have already glanced at the local treatment before ulceration has taken place. After this period, sedative applications do not succeed, and moderate stimulants alone seem best to afford relief. In fact, the inflammation has now acquired much of the character of a malignant erythema, and requires warmer applica- tions than phlegmonic sores. Yet a cure is rarely to be effected except by a caustic or knife. When the poison was supposed to be of an acid character a solution of the alkalies was employed to cor- rect it, and the ammonia produced from burnt toads was at one time in very high repute. It was afterwards conceived to be of an alka- line nature ; and various acids, and particularly the carbonic acid gas, were regarded as the best antagonists. Who first employed it for the present purpose is not known; but it stands recommended as early as 1776, in an article of Magellan, inserted in Roster's Jour- nal ; and an easy and convenient mode of application has lately been contrived by Dr. Ewart of Bath. Dr. Crawford, however, for the same purpose preferred a lotion of muriatic acid diluted with three or four times its weight of water. Carminati and Senebier applied the gastric juice of animals; but poultices of carrots or charcoal have of late years been in more general reputation. All these have a considerable influence in correcting the oppres- sive fetor, and keeping the sore clean; but whether they go beyond this has been doubted. Yet even this is of great importance, since such an effect must necessarily give some check to the spread of the ulceration, afford solace to the patient, and probably improve the nature of the discharge itself. And hence many writers have been sanguine enough to expect an entire cure from such processes ; and others have given accounts of such cures nearly accomplished ; but which seem seldom, if ever, to have been rendered complete. Fomentations of hemlock and various other narcotics have been also had recourse to, and sometimes tepid baths of the same, in which the patient has been ordered to sit for twenty minutes at a time ; and temporary benefit has sometimes followed the use of these means ; but they have often been tried with as little avail as the sucking of toads, which was at one time a fashionable remedy, and esteemed of great importance, the animal* being feigned to expire in agonies as the poison of the ulcer was drawn out, and its surface assumed a better aspect. Bouifey, who was a witness to their use, vol. rr. 69 546 Htf.MATICA. [CL. III.-OR. IV. tells us, and probably with some truth, that they did more harm than good,* and dealt out more poison than they took away. The era of this invention is unknown, but it was still in use, about half a century ago in our own country if we may judge from one of the private letters of Junius to Woodfall, who alluding to the princess dowager of Wales, at that time afflicted with a cancer that destroy- ed her in January 1772, asserts that " she suckles toads from morn- ing till night.'"t One of the best detergents appears to be arsenic finely levigated and sufficiently reduced in strength by an union with calamine or some other ingredient. It is also one of the best caustics, in a sim- ple or more concentrated state, and was freely employed as such by Mr. Justamond. Guy's powder, which we have already noticed, is used externally for the same purpose. We have already observed that sheets of lead, among other pre- parations of this metal, were applied to the cancer about forty or fifty years ago, and bound over ft with some degree of pressure. But a pressure of a much severer kind together with the use of the same metallic sheeting, has of late years been employed by Mr. Young and apparently in many cases with a very salutary effect, so far as relates to checking the spread of the disease, a diminution of the tumour, and an improvement of the nature of the discharge. The plan, however, has failed in many instances; and how far it may have produced in any instance a decided cure, the author can- not positively affirm. The sheet-lead is applied with a considera- ble tenseness of compression by means of plaster-straps, tin-plates, folded linen, and appropriate rollers. The force employed how- ever is less severe at first, but progressively increased; and the change of action is with much more reason ascribed to the sedative effect of the mechanical pressure than to that of the lead. After all, when the cancerous character of the tumour is once decidedly established, there is little dependence to be placed]? upon any plan but that of extirpation by a caustic or the knife. The actual cautery as employed by M. Maunoir, of which we shall have to speak more at large when discussing the genus Ulcus, may per- haps be most advantageously made use of in small cancers of the face, but the knife is the preferable instrument where the organ is large and extensively affected. Mr. Bell advises an early perform- ance of the operation; Mr. Pearson, that we should wait till the extent of the disease has fully unfolded itself, so that no morbid part may be left behind. Yet some parts may be doubtful even at last, and, wherever there is the least suspicion of this, they should un- questionably be removed along with the more decided portion of the morbid structure. Even this remedy, however, can only apply to exterior organs. In all other instances, the practice is melancholy from the first. * Journ. de Med. Tom. 1.XII. t G. Woodfall's Edition, Vol. I. p. *241.

The term lues is derived from the Greek Xva>, " solvo, dissolvo"— u to macerate, dissolve or corrupt;" and agreeably to the common rule of expressing the power of the Greek v by a Roman y, should be written lyes, as in the case of Lyssa, and Paralysis, both of which are derived from the same root; but lues has been employed so long and so generally, that it would be little less than affectation to attempt a change : and in allucinatio, or hallucinatio, from the Greek xXva or xXva-n, we are supported by a similar example of deviation from the common rule. It appears to have been known to the world from "an early age, as I have remarked in the running comment to the volume of No- sology, that acrimonious and poisonous materials are, at times, se- creted by the genitals, capable of exciting local, and perhaps con- stitutional affections, in those who expose themselves to such poi- sons by incontinent sexual intercourse. Celsus enumerates va- rious diseases of the sexual organs, most of which are only refera- ble to this source of impure contact; but the hideous and alarming malady which was first noticed as proceeding from the same source towards the close of the fifteenth century, and which has since been called almost exclusively venereal disease has suppressed, till of late, all attention to these minor evils, in the fearful contemplation of so new and monstrous a pestilence; to various modifications of which most of the anterior and slighter diseases of the same organs seem to have been loosely and generally referred; as though there were but one specific poison issuing from this fountain, and conse- quently but one specific malady. On which account, much confusion has arisen in the history and description of the disease ; and syphi- lis, its most striking species, though commonly admitted, as we shall see presently, to be comparatively of recent origin, is by Plenck,* * Beobachtungen, &c. 11. 548 H^EMATICA.

Richter,* Stoll,t and other writers of considerable eminence, re- garded as of far higher antiquity; asserted by Lefevre de Ville- brunej to have existed eight centuries before the expedition of Co- lumbus to America, and by De Blaguy§ to have been extant in the Mosaic age. The keen and comprehensive mind of Mr. John Hunter first call- ed the attention of practitioners to the idea of different poisons and dif- ferent maladies ; and the subject has since been pursued by Mr. Aber- nethy with a force of argument, and illustrated by a range of exam- ples, that seem to have put the question at rest. Mr. Abernethy has sufficiently established that, independently of the specific disease now generally recognized by the name of syphilis, there are nume- rous varieties of some other disease, perhaps other specific diseases, which originate from a distinct poison, possibly from several distinct poisons secreted in the same region from peculiarity of constitution, or causes hitherto undiscovered ; and which are accompanied with pri- mary and secondary symptoms that often vary in their mode of ori- gin, succession, and termination, from those of genuine syphilis, though in many instances they make a striking approach to it; and to which, therefore, Mr. Abernethy has given the name of pseudo- syphilitic diseases. Whether these really constitute distinct species, issuing from dis- tinct sorts of infection, or are mere varieties or modifications of one common species produced by one common morbid secretion, has not yet been sufficiently determined. In this ignorance upon the subject, it is better, for the present, to regard them in the latter, as being the more simple view ; and with this preliminary explana- tion the expediency of allotting the two following distinct species to the genus lues will 1 think be obvious to every one. 1. lues syphilis. pox. 2.----syphilodes. bastard pox. * Chir.

The vulgar term for the ulcers is Chancres, and the vulgar name for the disease is Pox, formerly Great-Pox* as contradistinguished from variola or small-pox, on account of the larger size of its blotch- es. It was also very generally called French Pox, as being suppos- ed to be a gift to Europe from the French nation. There is some uncertainty concerning the origin of the specific term syphilis, which was probably however invented by Fracasta- rio about the close of the fifteenth century, from the Greek me of which cases, however, it seems necessary to suppose the existence of a cut or crack or some other breach of surface in the skin, and particularly about the lips, with which the syphilitic virus must have come into union. And it is hence easy to conceive how much more readily it may be communicated by the insertion of an exotic tooth,§ by bleeding or scarification with an infected lancet,|| or by the attend- ance of ans infected midwife,1T who has sometimes given the com- plaint both to the mother and the child. A very melancholy instance of infection is related by Dr. Barry of Cork, communicated by a woman who was in the habit of draw- ing the breasts of puerperal patients, and who, upon examination, was found to have chancres on the lips and roof of her mouth ; probably caught from some impure person in the course of her vocation. From the numerous engagements of this woman, the disease had spread very widely ; and the rapidity of its progress was as striking as the manner of its communication. " The nipple,11 says Dr. Barry, " first became lightly inflamed, which soon produced an excoriation, with a discharge of a thin liquor: from whence red spreading pustules were dispersed round it and gradually spread over the breast, and, where the poison remained uncorrected, produced ulcers. The pudenda soon after became inflamed, with a violent itching, which terminated in chancres that were attended with only a small discharge ; and, in a short time after, pustules were spread over the whole body. It finished this course, with all these symptoms, in the space of three months^ The disorder made a quick and rapid progress in those who firsff-eceived it, they not being apt to suspect an infectilh of this nature in their circum- stances. The husbands of several had chancres, which quickly * Reid, Diseases of the Army, &c. Gruner, die Venerische Austehung durcl\ gemeinschafftlische Trinkgeschirre.

But such of them escaped who had timely notice of the nature of the disease before the pudenda were affected. Some infants received it from their mothers, and to the greatest part of them it was fatal.'1* Where a wet-nurse and the infant she suckles are both affected, and there is a doubt which has communicated it to the other, collateral circumstances will assist us much: but where the one, as is usually the case, has constitutional symptoms, and the other only local, the former must have had the disease longest, and conse- quently have been the sodfce of contamination. Such, however, is the unsusceptibihty of some idiosyncrasies, that the matter of syphilis, like that of small-pox, seems to have no effect upon them, and they are proof against its activity. I once knew a young physician who finding himself to be thus naturally protected, fearlessly, and for the sake of experiment, associated himself with females in the rankest state of the disease, and escaped in every instance. In like manner Schenckt gives us a case of an infant rendered syphilitic through a diseased father, while the mother remained unaffected; and Mauriceau and other writers, give cases of infants which have been fortunate enough to avoid infection though born of syphilitic mothers :| while Pallas asserts that the Ostiacks have a general immunity from the disease under whatever form it offers itself.§ The medicines which have been chiefly had recourse to, or have been found most serviceable in curing syphilis or arresting its progress, are narcotics, diluent diaphoretics, diuretics, drastic pur- gatives and those which introduce a large portion of oxygene into the system ; practitioners having directed their attention at different times to rendering the vascular fibres inirritable to the specific acrimony of the disease, to expelling it by some of the emunctories opening externally, or to dulcifying it by a chemical combination. Of the narcotics, recourse has been chiefly had to opium, conium, solanum, and bella-donna, manifestly upon the principle of their being sedatives, and hence rendering the system inirritable to the syphilitic virus. This some of them accomplish in a very consider- able and desirable degree ; and particularly opium which has been mostly trusted to, anfftried upon a wider scale than any of the rest. It moderates and alleviates every symptom; and, from a cause not well ascertained, may be taken in%ery large doses with less incon- venience in syphilis than in almost any other disease. From "its palliative effects it has been supposed by many practitioners capable of producing a radical cure ; and numerous accounts to this purpose have .been published by those whose judgments have been unduly * Edin.

On these accounts it is not necessary to enlarge: they have been long before the world, and have called forth other trials which have not proved equally successful. Nar- cotics in general, and opium beyond the rest, add considerably to the efficacy of other means, and particularly of mercury; but of themselves they are not competent to remove the complaint, and consequently are not to be depended upon. The hst of warm and diluent diaphoretics that have been employed as remedies in syphilis are very extensive ; but it may be sufficient to enumerate the following: mezereon, guiacum, sarsaparilla, sapo- naria, bardana, smilax, and one or two species of asclepias or swallow-wort. All these are supposed to be serviceable by exciting a determi- nation to the skin, and throwing off the syphilitic poison, as various other poisons are thrown off, from the surface: and in very warm climates many of them are said to operate a radical cure; though the statements to this effect are rarely such as we can depend upon. Some of them, moreover, as the saponaria or soap-wort, and smilax or china-root, possess a viscid or unctuous principle, which has been supposed ofuse in obtunding the acrimony of the poison, and thus blunting its effects even before it is discharged from the body. The soap-wort has the advantage of being found in the hedges of our own country. 'Bhey have all had their day, and the only one at present in much request is sarsaparilla, of the actual amount of whose virtues it is difficult to speak with precision. Like the lobelia syphilitica or blue cardinal-flower, which is a purgative plant, it owes its earliest reputation to the American tribes; and when first imported into Europe by the Spaniards about the year 1563, it had the character of being a specific for the venereal complaint. From being ex- tolled, however, too highly, for it has never fulfilled this character in the old world, it has since sunk, like many other useful medi- cines, into a very unmerited contempt, insomuch that Dr. Cullen allows but eight lines to its history and qualities, in the course of which he tells us that if he were to consult his own experience, he would not give it a place in the Materia Medica, as he has never found it an effectual medicine in syphilis or any other disease.* The London College, however, have evinced a different opinion, for they have adopted it under various forms: and Dr. J. Thomson, of the Depot Hospital, Edinburgh Castle, has been so highly satis- fied with its antisyphilitic powers, that he has for some years relinquished the use of mercury altogether in favour of a new mode of practice, which consists chiefly in the employment of sarsaparilla.1 Upon a very large scale he has met with very great success ; though he candidly acknowledges that the secondary s}rmptoms of the disease have required a longer time to be overcome under the new * Mat.

Its fair pretensions appear to be those of a mild stimulant and diaphoretic. It is hence in many cases a useful auxiliary to mercury : but I have chiefly found it succeed in chronic cases where the constitution has been broken down perhaps equally beneath a long domination of the disease and a protracted, and apparently inefficient, mercurial process. In eonnexion with a milk diet and country air, and with a total aban- donment of mercury, I have here often found it of essential import- ance, and have seen an incipient hectic fall before a free use of it in a week. Its best form is the old one of the decoction of the woods. The syphilitic poison has also been often attempted to be thrown out of the body by exciting the excretories of some other organ than those of the skin or in conjunction with them. Thus the flam- mula Jovis, or upright traveller's joy, the clematis recta of Linneus, which acts powerfully both on the surface and on the kidneys, is said to have been employed with great advantage, and was at one time in high and extensive estimation. It was given in the form of an infusion of tbe'leaves, and Dr. Stoerck, with his usual liber- ality, assigns it an extravagant praise, informing us that it effectual- ly subdues all the secondary symptoms of inveterate head-aches, bone-pains, nodes, ulcerations of the throat, and cutaneous erup- tions.* The lobelia syphilitica of the American Indians has a still faflrer claim to notice. It is a drastic purgative, uniting something of the stimulant and narcotic powers of tobacco, to which it has some resemblance in its taste. In the simple life and inirritating diet of the American tribes, it is possible that it may have proved as suc- cessful as it is stated to have done ; but it has completely failed in Europe. Of the antisyphilitics, whose influence seems to depend on their being loaded with oxygene, the principal are the mineral acids, and the metallic oxydes. Of the first, the nitric has chiefly been made a subject of experi- ment in our own country, though the sulphuric has been employed abroad.! How far it exercises a chemical power upon the syphi- litic virus, and forms a new and blander substance with it, is uncer- tain. Its general effects are, as we might expect them to be, tonic and sedative ; whence the appetite is increased, a greater rigidity or firmness is given to the living fibre, and a greater density to the coagulable lymph: the action of the bowels and even of the blad- der being diminished. Besides these, it has a particular effect on the mouth approaching to that of ptyalism, for the gums are ren- dered slightly sore, the mouth and tongue become moist, and in In- dia and other warm climates a real salivation is said to ensue. Un- *■ Libellus quo demonstratur herbam veteribus dictam flamtnulam Jovis possa tuto exhiberi. Vienn. 1769. t Crato, Epist. v. p. 293.

The acid he was in the habit of employing was a direct aqua regia as already noticed in the treatment of jaundice ;* and with the internal use of this, he combined that of the acid bath as there also particularly specified. His object was to effect a cure without incurring any of the evils so frequent upon a mercurial course; and to this object the proposed plan has, in his opinion, given com- plete success. It would have been happy for the world if this suc- cess had been permanent and universal; but the plan has since fallen in its reputation not much less in India than in Europe. The metallic oxydes have offered a large field for experiment; and almost all the metals have been had recourse to in rotation, as copper, iron, antimony, mercury, arsenic, and even gold. The pretensions of arsenic are certainly considerable : it forme the ordinary medicine employed in syphilis by the cabirajas or native Indian physicians, who depend upon it as a specific. They give it in the form of white arsenic in combination with black-pepper, as we shall notice more at large when treating of elephantiasis, for which also it is esteemed a powerful remedy. The only auxiliary is a ca- thartic of manna dissolved in a decoction of nympha? a nelumbo. Of the effects of any of the preparations of gold we know but little. Many of them were in high repute formerly as a cure for various cachexies, and are said to have been used with success in syphilis.f They have since been repeated in France, and are re- ported to be entitled to all the distinction they have at any time attained; but as a train of experiments upon this subject is still in hand we may hope for more'certain information in a short time.J Antimony, and perhaps a few other metals are useful auxiliaries; but, in fact, the only metal, and I may add the only medicine, on which we can confidently rely for a perfect cure of syphilis in all its stages in our own climate, is mercury. This has been tried from an early period in almost every variety of preparation ; and, provided a sufficiency of it is introduced into the system, in every variety it has been found to succeed: so. that in the present day the peculiar form is regarded of less importance than on it? first use ; though we may observe that it seems to be most rapidly efficacious in those forms that introduce the largest propor- tion of oxygene into the system. And as it operates chiefly, like most other medicines, through the medium of circulation, when it once becomes mixt with the current of the blood it is equally effi- * Vol. I. Cl. I. Old. 11. Gen.

Mercury is an universal stimulant, and increases the action ol all the secretories at one and the same time ; for it operates simulta- neously on the intestines, the skin, the salivary glands, and even the bladder; though it displays itself chiefly by its action on the saliva- ry glands. It has also, when given in moderate doses, considerable pretensions to a tonic power, though this is overwhelmed by its stimulant effects when the dose is considerably increased. It seems therefore to unite most of the virtues of the preceding remedies, excepting the sedative; and hence it is greatly improved by the addition of opium and camphor, which give it the quality it stands in need of. Independently, however, of its combining in itself many of the virtues of the preceding remedies mercury seems also to possess seme specific virtue unknown to the rest; for we can associate all the general qualities by a combination of different medicines with- out producing the same result. Mercury, indeed, to these general qualities adds that of peculiarly stimulating the salivary glands, which the other remedies employed in syphilis do not at all, or never in an equal degree; but that its specific power as an antitode does not depend upon its being a sialogogue is clear, because while it has sometimes excited salivation without effect, it has at other times produced a perfect cure without any salivation whatever, for in some idiosyncrasies the salivary glands are not affected by its ir- ritation. Dr. Cullen, however, who had a mortal aversion to considering any medicine in the character of a specific, denies that mercury is a specific in syphilis, as he does also that it is an attenuant of the blood or an antidote to the disease. It is in vain to point out to him its specific influence upon the salivary glands, or its specific action upon their mouths; he denies the whole, and contends that mercury might travel, and perhaps would travel for ever in some other direction, were it not for the friendly interposition of the am- moniacal salts of the blood, which he fancies to have a close affin- ity with mercury as they have also with the salivary glands ; in con- sequence of which, they take the mercury by the hand and intro- duce the one stranger to the other :* thus solving the difficulty like a divinity in the catastrophe of a drama. The result of the whole, in the opinion of Dr. Cullen, is that mercury cures the venereal disease, not by producing any change in the state of the fluids, but entirely by giving a stimulus to the excretories at large, by what- ever contrivance it reaches them, and thus increasing the excre- tions and washing out the poison from the body. That it does this is highly probable; but this alone is not suffi- cient, for fresh poison is continually forming by the process of as- * Mat. Med. Part. n. Ch. xvn. p. 443—450.—See also the present Work, Vol I. p. 5!i. «3E. VI.-*P. U] SANGUINEOUS FUNCTION. 561 similation, or the conversion of some part of the fluids it comes in contact with into its own nature ; since if it wore not so, and the minute drop of virus that excited the disease at first remained with- out any increment, there can be no question that such a general «couring of the system would be unnecessary, and that the ordinary evacuations would be sufficient to throw it off. And hence we .have not only to carry away the poison that is actually present in the ves- sels but to prevent the formation of new. Now it is in this power of prevention that the specific virtue of mercury seems to consist; and this it is that renders it paramount to all other remedies in the cure of syphilis. It is not only an evacuant but an antidote. By what means, however, it becomes an antidote, or exerts its specific power, we know not. The matter of a chancre mixed up with a quantity of Plenck^ gummy solution of mercury has been applied to a sound person without occasioning eith- er a chancre or any other syphilitic symptoms. And it has hence been supposed that mercury neutralizes the syphilitic virus and produces a third and harmless substance. As it has been further supposed that it is by the disengagement of the oxygene which the various preparations of mercury introduce into the system that this effect is accomplished. All this is ingenious and may be true, but the evi- dence does not come home to the conclusion. Even the experi- ment with chancrous matter and the mercurial solution has not been -Mjtisfactoriiy performed; and if the result were as here stated, the matter while it has no power of assimilating the solution into its own nature, as it has the fluids of the human body, may only have been rendered inert by simple dilution. We have said, that provided a sufficient quantity of mercury be introduced into the system, the particular preparation is of no great importance. Van Swieten preferred the oxymuriate, and every one followed his example. The calcined mercury came next into po- pularity and triumphed over everv other form. It was the leading article of most of the secret remedies that were sold for the com- plaint and especially of Keyseris pills, the receipt for which was purchased with great formality by the French government, with an express provision not to make it public till the inventor's death.* These pills, however, which consisted of nothing more than mer- cury calcined by a needlessly operose elaboration, and mixed up with manna, were found in many cases to irritate the bowels even when united with aromatics and opiates; and hence they gradually yielded on the continent to Plenck's solution, which still holds a considerable sway. In our own country, it is now most usual to employ the mercurial pill, or calomel, either alone or together with mercurial ointment. Yet, whatever plan is preferred, much caution is necessary in carrying it into effect; for the older practitioners who employed larger doses * Des Dragees ou Pilules de M. Keyser. P;'.

IV' did as much mischief to the constitution by the antidote as it had received by the infection. If calomel be employed, about two grains a day will be sufficient, guarded when necessary by a grain of opium, and if the ointment be preferred half a drachm of the strong mercurial ointment may be rubbed in night and morning. If the disease be not severe or of long standing, it will not be necessary, with a little management, to produce salivation, which in most in- stances may be regarded only as a test that the system is thoroughly impregnated with the medicine : but in chronic cases we ought not to be satisfied without it. In all cases of its use, but particularly in cases of salivation, care should be taken to avoid cold, and flannel should be worn next the skin; for it is important that the excretories should harmonize in an increased defluxion. It is also of importance that the diet be light and simple, as the pulse is usually accelerated, and, by a stimu- lating regimen, would be so much quickened as to do serious mis- chief. Mr. Hunter lays no stress upon this point but it ought by no means to be neglected. If a buboe have formed in the groin the mercurial ointment is best rubbed in a little below it, as it would increase the inflamma- tion if applied to the tumour itself. In about a week or ten days, the mouth will become slightly sore, when the further use and pro- portion of the ointment or other preparation must be regulated by the violence or duration of the complaint. Where salivation is de- termined upon, the flux should be suffered to continue for about a month. An.injudicious use of mercury, or indeed any use of it, in highly irritable habits, will sometimes excite a very troublesome erythema that spreads itself in trails or patches over the whole surface; com- monly however commencing about the genitals, and lower limbs. It is accompanied with a painful tenderness and itching of the skin, and, as the erythema meanders onward, the trails or patches first observed heal as new ones make their appearance. We have al- ready glanced at this affection under the vesicular species of ery- thema.* Mercury must in this case be desisted from, the bowels be loosened with some gentle aperient and the irritability opposed by sedative and mild cardiacs as camphor, guaiacum, and sarsaparilla; and particularly by the mineral acids. * Vol. u.

Jfcistarti tyo\\ #LCERS INDETERMINATE IN THEIR CHARACTER ; SYMPTOMS IRREGULAR I& THEIR APPEARANCE ; USUALLY YIELDING SPONTANEOUSLY ; VARIOUSLY AFFECTED BY A COURSE OF MERCURY. I have already observed at the opening of the present genus that the species before us is designed to include a multiplicity of affec- tions which in many of their signs have a close resemblance to syphilis, but differ from it in the progress of the symptoms as well as in the means that are necessary for a cure. Such affections are of high antiquity, and some of them appear to be glanced at in the sacred records. By Celsus the subject is touch- ed upon scientifically: it has been taken up in modern times by Mr. Hunter with that spirit of inquiry which peculiarly distinguish- ed him,* and has^since been pursued by Mr. Abernethy with a kindred comprehension and genius.f The subject, however, is still in its embryo. Mr. Hunter considered his own remarks rather as hints for others to prosecute than as a complete account of it. And though Mr. Abernethy has accumulated facts and cases, and ably illustrated them with observations that sufficiently establish these hints, and give something of a body to the outline, we are still in want of distinctive characters, and cannot determine with any de- gree of accuracy whether the wide group of complaints that fall within the present range of contemplation, are mere varieties of a common species produced by a common poison, or distinct species dependent upon distinct poisons, as discriminate from each other as all of* them are from proper syphilis. It was regarded by Mr. Hunter as a pathognomic character of syphilis, first that it never ceases spontaneously; secondly, that it is uniform and progressive in its symptoms; and thirdly, that itis only to be cured by mercury. How far the last position may admit of such a modification as may leave it open to occasional exceptions in other climates, it is n'ot worth while to inquire. In our own, the whole of these dicta stand upon a rock of facts progressively accumulating and confirmed by every day's experience. And the family of complaints included under the name of bastard-pox, or pseudo-syphilitic disease are in direct contradistinction to all of them; for they are perpetually giv- ing proofs of a spontaneous cessation ; they are irregular and de- * Treatise on the Venereal Disease. + Surgical Observations qn Diseases resembling Syphilis.

In illustration of these remarks, 1 might refer to the observations' of those who have been attentive to the subject on a large scale; but I refer more particulaily to the collection of cases which Mr. Abernethy has printed in the work already adverted to. The disease ordinarily commences with local symptoms, though not always: but the local symptoms have a less resemblance to those of genuine syphilis than the constitutional by which they are suc- ceeded. A few foul and highly irritable sores are unexpectedly discovered on the genitals, commonly larger than chancres, and less thickened and indurated, about the size of a six-pence, and frequent- ly sprouting with fungous granulations. Rarely, but very rarely, they have the guise of a true chancre: so rarely, indeed, that of the twenty cases contained in Mr. Abernethy's book, the fifth is the only one that answers to this description. These are sometimes succeeded by buboes; and sometimes not. And where buboes take the lead they run their course more rapidly, and with more violent inflammation than in the true disease, and spread to a greater num- ber of circumjacent glands. These often heal by the ordinary means without mercury, or constitutional symptoms of any kind. But not unfrequently, in a few weeks or months they fare followed by a soreness and ulceration of the tonsils, copper-coloured spots over the body, and nodes or swellings of the periosteum in various bones; and sometimes these symptoms change their order of succession, or appear single. In a few instances, the constitutional symptoms take the lead and the local follow, of which Mr Abernethy's fourth case affords an example. The patient here perceived, first of all, a small ulcer on the breast near the nipple, after having suckled a nurse-child about four months. It was of the size and shape of an almond, and was ascribed to the child's having a sore nose and lips. A gland in the axilla soon swelled and subsided: but in about two months the patient had a severe febrile attack accompanied with a sore throat; from this she soon recovered, but had shortly afterwards a copper- coloured eruption scattered over the body; and upon the disappear- ance of this, white blisters about the pudenda which gave her pain in walking. About a week afterwards her husband found a sore on the penis covered by a black scab, of about the size of a sixpence, with a base neither hard nor thick, but with the surrounding skin much inflamed. Another formed in the course of the lymphatics towards the groin: the inguinal glands enlarged, and one of" them suppurated ; and an eruption of a papulous erythema, ushered by a few febrile symptoms, followed in about three weeks. The sores were twice touched with lunar caustic, and, as well as the bubo, we're afterwards washed with calomel in lime-water: they gradual- ly healed. Both patients recovered, the wife with little assistance from mercury, having taken only a few compound calomel pills with small doses of nitric acid; the husband without mercury altogether,^ GE.TI.HSP.il.] SANGUINEOUS FUNCTION. . 56S except that a dose of calomel was once administered with other aperient drugs as a purge. In all these cases, we meet with a virus that seems to be more active and irritating than that of genuine syphilis, but which, while it pursues, though with much irregularity, the same general path, runs through its course much quicker, and is more effectually coped with by the natural strength, or remedial instinct of the constitu- tion. And hence, all that we are here called upon to do in the way of treatment is, to support the general vigour, and second the in- stinctive effort. This is best to be accomplished by tonics and gentle stimulants, and, where necessary, by sedatives. The mineral acids are the best means of supplying the first intention; camphor, the decoction of the woods, and the compound calomel pill, where small doses of mercury do not irritate, the second; and opium the third : though to this last it will rarely be necessary to have re- course at all. The distinction between these affections and genuine syphilis is frequently difficult, but of importance : since, as a full use of mercu- ry seldom seems to do good, and often does serious mischief in the former, such a plan has a chance of overwhelming the constitution with a second disorder instead of freeing it from a first. To this family of maladies we are probably to refer the disease, which, for a century or two, has been known in Scotland by the name of sibbens or sivens, literally rubula, or rasp-berry eruption: and which seems to he a variety of lues rendered hybrid by passing through a constitution already contaminated with genuine rubula or yaws. The locai symptoms have a much nearer resemblance to those of bastard-pox than of genuine syphilis, but, in its constitution- al progress, after the ordinary affection of the fauces, the disease has a tendency to throw forth, over the surface, an eruption of tubercles which speedily degenerate into fungous ulcers resembling yaws, rather than an eruption of copper-coloured spots : which tu- bercles sometimes show themselves also in the throat itself. The constitutional disease spends itself chiefly on Jhe surface, and the bones are rarely affected. With these exceptions we may agree with Dr. Gilchrist,* and Mr. Hill of Dumfries,! that it has not a symptom which does not accompany the lues venerea (meaning syphilis J through all Europe; that both are equally infectious; both only communicated by sexual intercourse or other familiar contact; and both beneficially treated by mercury; which, they affirm, is the only remedy to be depended on. Mr. Hill tells us that it was in- troduced into the vicinity of Dumfries, about the year 1772, " by some pocky soldiers, who, to prevent their debauching in town, were disposed through the neighbouring villages." Even upon his own showing, however, a much looser and blander exhibition of mercury than is sufficient for the cure of a confirmed syphilis, will * Account of a very infectious Distemper, Sic.

It is pro- bable, therefore, that sibbens might be eradicated by other means as well; but these gentlemen, notwithstanding the peculiarity of many of its symptoms, regarded it as a genuine syphilis; and, in consequence, did not direct their attention to any other mode of treatment.

Thus applied, therefore, the term imports elephant-skin : in the same man- ner as the same national school denominated dandriff pityriasis, or bran-skin, from the skin, under this disease resembling branny scales; and another sort of scaly malady ichthyiasis, or fish-skin, from the resemblance of the skin, when thus affected, to the scales of fishes. There are, however, two diseases of a very different kind, which occur in the translations of the Greek and Arabic wri- ters under the name of elephas, elephantia, or elephantiasis; that immediately before us, and the thick leg of Barbadoes and other hot climates: and, as the former of these has also, by many of the Ara- bian writers, been called lepra or leprosy, and especially black le- prosy, though as distinct from genuine leprosy as it is from the thick-leg; and, as the common term lepra has been continued in the translations of such writers, and copied from them by writers of our own times, an almost impenetrable confusion has been thrown around the whole of these diseases; and they have, even by mo- dern writers been strangely huddled together, and contemplated as mere modifications of one and the same malady, or as having some other connection which does not in reality exist. My attention was particularly called*to this subject about five or six years ago by an application from Dr. Bateman, who was then preparing his work for the press, on Cutaneous Diseases, to assist him in unravelling it from the thorny maze in which it was at that time enveloped, and, as the following letter from him, written in conse- quence of my acceding to his request, shows the real difficulty of GE.

I be- lieve the proper tubercular elephantiasis of the Greeks; was called juzam, or aljuzam by the old Arabians {dsjuddam and madsjuddam by the moderns, according to Niebuhr.)* " If so, do the other Arabian writers also designate the proper elephantiasis, by the same appellation ?—For instance, is it used by Haly Abbas ?T " Again, what is the Arabic term applied to the thick leg (which most of the translators call elephantiasis, but which the translator of Haly Abbas, calls elephas, thus distinguishing it from elephantia ?)— The thick leg is described by Haly Abbas,J by Avicen,§ by Rhases|| and by Avinzoar.lF The translators of the other works in these places, use the word elephantia^ " Thus, the proper elephantiasis is called elephantia by (the trans- lator of) Haly Abbas, and lepra by (the translators of) Avicen, Rhases, and Avinzoar.—And the thick leg is the elephas of the for- mer, and the elephantia of the latter.—My chief inquiry is, whether the difference is only among the translators, or whether there is likewise a want of uniformity in the nomenclature of the original writers. " En passant, I may observe, that some farther confusion has arisen among the translators, respecting another leprous disease, as it has been called, which the Arabians seem to have considered as having some affinity with the proper elephantiasis (juzam,) but yet is materially different in its symptoms ; and which they have denomi- nated baras, or barras, and albaras, and which appears to accord ac- curately with the leuce of the Greeks, and the vitiligo (species 3.) of Celsus.—If the Hebrews did Sot apply the term (translated) leprosy, to several affections of the skin) such as the scaly lepra graecorum, the psoriatis of Dr. Willan, and the leuce, which I suspect they did:) this leuce or baras would seem to be the unclean leprosy described in Leviticus, Cap. xm ** " if your knowledge of the oriental languages will enable you, together with your knowledge of these diseases, to disperse some * See Avincen.

The substance of the author's reply to this letter, already given in a note to the volume of Nosology, but which ought not to be omitted on the present occasion, was as follows : . . n The Greeks became first acquainted with the elephantiasis from their casual intercourse with Egypt. To this quarter, Lucretius, adopting the common opinion, ascribes its origin ; Est Elephas morbus, qui propter fluraina JVili, Gignitur iEgypto in media neque praeterea usquam.* High iip the Nile, mid Egypt's central plains, Springs the Black Leprosy, and there alone. Arabia, however, seems rather to have been the prolific source of this terrible scourge than Egypt: if we may judge from what seems highly probablemamely that this is the disease with which Job was afflicted in Idumea, a part of Arabia, as described in the sacred poem that bears his name under the appellation of fiJHS y^l " the stroke of the scourge," 'and which affords, without question, the most ancient record in the world, composed in a mixt language of Ara- bic and Hebrew; and if we add to this the still more powerful argu- ment that the Arabic name of the disease has extended itself all over the east, and is almost the only name by which it is known in Egvpt, Persia, and India, in all which regions the disorder is about equallv common. Yet the Arabic name is not elephas or elephantiasis, but juzam, literally "disjunction, amputation," vulgarly, indeed, and more generally pronounced and written judam from a root which imports " erosion," " truncation," " excision;" evidently referring to the destructive character of the disease, and the spontaneous separation of the smaller menibers, as the fingers and toes when severe in its progress. The Arabians, however, have a malady, but of a very different kind, to which they also give the name of elephas, or elephant affec- tion, in their own language dalfil, which is literally morbus clephas: and which they sometimes contract tofil, or elephas alone. It is the " swelled, tumid, or Barbadoes leg," of modern writers, the bucne- mia tropica of the present system. And, on this account, when learn- ing, and especially medical learning, found an asylum, during the dark ages, at the splendid courts of Bagdat, Bassorah, and Cordova; and the best Greek writers were translated into Arabic, or the best Greek and Arabic into Latin, two different diseases were found to possess a like name : for the Greeks, notwithstanding that they had elephantiasis to signify juzam, could only translate dal fil by elephan- tiasis also. And hence arose that confusion of the two maladies which has continued to the present moment, notwithstanding the * De Rer. Nat. vj, 1112. ©E. VII.] SANGUINEOUS FUNCTION. 569 wide distinction between them, the one being a tubercular affection of the whole body, while the other is a scaly affection of only par- ticular parts, and commonly of not more than a particular limb. The leprosy properly so called, the leuce (xivxv) of the Greeks, and the baras or beras of the Arabians, was, by many of the Arabian physicians, and very generally among the people, supposed, in vari- ous cases, to terminate in juzam or elephantiasis, as though this also was nothing more than a different stage or degree of the same disease. And hence another error and perplexity in medical study. Alsahavarius thus unites them, and they are jumbled together or explained alike in nearly all the oriental dictionaries; in which beras or leprosy, and juzam or elephant-skin, are, almost without an exception, regarded as convertible terms. This oriental confusion of two very different diseases was readily copied by the Latin trans- lators, till at length, both in the east and west, beras or lepriasis, though literally scale-skin, became a sort of family name for almost every foul disfigurement of the skin, whether tubercular, or scaly, cutaneous or constitutional. And, on this account, elephanti-'sis and leprosy, and several other diseases even in the nosology of Linneus, are included under the term lepra; all which the disciples of this school, extending a principle very widely adopted by them, ascribe to animalcules drunk in with the common beverage of water, espe- cially the gordius marinus. The author ought not to conceal Dr. Bateman's acknowledgment of this communication, and his assent to its explanation contained in the following opening of a letter received a few days afterwards : " I thank you sincerely for your ready and interesting communi- cation, which satisfactorily explains the point, respecting which I was the least able to obtain satisfaction from the translators, viz. that the Arabians had applied the term elephant (elephas, according to the able translator of Haly Abbas,) or fil, as you state to the swelled leg. This is some apology for the appropriation of the Greek term elephantiasis, (though it actually denoted a different disease) to the Arabian thick leg ; but the appropriation of lepra, which is never mentioned by the Greeks but as a " superficial, rough, and scaly affection," to the tubercular juzam, has unfortu- nately misled and confused us for a thousand years " Dr. Bateman adds, that he apprehends the term elephantiasis had also a reference to the magnitude and duration of the disease, inde- pendently of the appearance of the skin. And it is very probable, as the malady was likewise sometimes denominated leontiasis, that the formidable and frightful aspect of the patient labouring under it, may have been hereby compared to the general exterior of both the elephant and the lion: for while Aretaeus tells us, in describing it, that " it is disgusting to the sight, and in all respects terrible like the elephant," Avicenna, affirms, " it renders the countenance ter- rible to look at, and somewhat of the form of the lion's visage." Besides the elephantiasis of the Arabians, we have a disease of the same kind, or which seems to be of the same kind, common to vol.. n. 72 070 HJLMATICA. [CL, II1.-OR. Ff. some parts of Italy, and another common to some parts of Spain; both which seem, indeed, to have issued from the Arabian stock. And hence elephantiasis, as a genus, offers us the three following species :■ 1. ELEPHANTIASIS AKABICA. ARABIAN ELEPHANTIASIS. 2.------------ITALICA. ITALIAN ELEPHANTIASIS. 5.-------»- ASTURIENSIS.

TUBERCLES CHIEFLY ON THE FACE AND JOINTS; FALL OF THE HAIR EX- CEPT FROM THE SCALP: VOICE HOARSE AND NASAL: CONTAGIOUS AND HEREDITARY. This species, which is the oldest of the three, is also the most in- veterate : for we do not know that the Italian species is contagious, though, like the Arabian, it appears to be hereditary: while the Spa- nish is, perhaps, neither contagious nor hereditary. In some parts of the world, indeed, even the present species is said not to be contagious, though all the writers concur in its being hereditary in every quarter. Thus Dr. Schilling, while he admits the latter effect, asserts that it is not contagious in Surinam : and Dr. T. Heberden asserts the same of this disease in Madeira. " I not on- ly," says he, " am a daily witness of communication between lepers and other people without the least ill consequence, but know seve- ral instances where a leprous husband (afflicted with the Arabian leprosy or elephantiasis) married to a sound wife, has cohabited with her for a long series of years, and had several children by her, without her having contracted the least symptom of the disorder, although the children have inherited it; and vice versa, between a leprous wife and sound husband."* That the disease, however, is contagious as well as hereditary in India and Arabia, we have the concurrent testimony of all the medi- cal writers of both countries, native as well as foreign ; so that there can be no doubt upon the subject. And hence, the Madeira and Surinam juzam should seem to be a variety of the oriental, influen- ced by peculiarity of climate or some other incidental cause. This severe malady, wherever it shows itself is sometimes slow in its growth, and continues many years without deranging the func- * Medical Transactions, Vol. I. p. 35. GE. VII.-SP.

The alse of the nose become swelled and scabrous, and the nostrils are preternaturally dilated; the lips are tumid; the external ears, particularly the lobes, are enlarged and thickened, and be6et with tubercles. The skin of the forehead and cheeks grows dense and hard, and forms large and prominent rugae, espe- cially over the eyes ; the hair generally, except on the head, falls off; the voiGe becomes hoarse and obscure; the external sensibili- ty is obtuaded or totally abolished, so that pinching or puncturing gives no pain. The tubercles at length begin to crack, and ulce- rate ; ulcerations appear in the throat and nostrils; the breath is intolerably offensive ; the palate destroyed; the nose falls off; the fingers and toes, from the increased depth and virulence of the ul- cerations become gangrenous, and separate, and drop off one after another. The mental powers suffer less than in the two other spe- cies : the dreams, however, are greatly disturbed, the manners, for the most part, morose and melancholy; and sometimes there is an inextinguishable desire of sexual intercourse. This disease is also known in the high northern latitudes of Nor- way and Iceland. In the last place, it is peculiarly prevalent, pro- duced, as Dr. Henderson justly observes, by the rancidity of the food usually fed on, wet woollen cloths, an insalubrious air, and want of cleanliness. It is called " Likthra," or " Putrefaction:" and a hospital is established for it in each of the four quarters of the island. It seems to be here both infectious and hereditary. " In its primary stage," says Dr. Henderson, " its symptoms are incon- siderable. A small reddish spot, scarcely larger than the point of a needle, breaks out at first about the forehead, nose, corner of the eyes and lips: and in proportion as it increases other pustules make their appearance on the breast, arms, arm-pits, which generally dry up in one place and break out in another without pain, till the dis- ease has considerably advanced, when they cover almost the whole body, give the skin a scabrous appearance, stiffen it sometimes in shining scales which fall off like dust, sometimes in malignant tu- mours and swellings. The patient, in the mean time, labours under lassitude of body, anaesthesia and lowness of spirits." The misera- ble progress is nearly a transcript of the description just given. The patient is so worn out with fatigue and melancholy, as to be of- ten tempted to make way with himself. He surrenders one part of the body after another to the insatiable malady; " till at length," says Dr. Henderson, " death, the long-wished-for deliverer, comes suddenly and puts an end to his misery."* The cure is extremely difficult; but a course of warm diaphore- tics succeeded by tonics and especially the metallic tonics, seems to have constituted the most successful plan. Hence a free use of sarsaparilla, mezereon, or guaiacum, has been found beneficial; and * Iceland, or the Journal of a Residence in that Island, Vol. i. p. 295, 8yo„ Edin. 1818. 572 H.EMATICA. [«- UI.-OR. IV- mercurial alteratives still more so; though salivation appears to have been uniform!v mischievous. Even the lobelia has had it« ad- vocates, and upon the ground of its proving salutary in syphilis it has probably also been sometimes serviceable in elephantiasis. Dr. Schilling endeavours to increase the determination to the skin, by advising a use of the warm-bath and gentle exercise, and embrocat- ing the bodv with spirit of wine or rum or exposing it to a vapour- bath of mastic, ohbanum, benzoin, or lavender. In India the cabirajas, or native physicians, after bleeding and purging, immediately apply to the metallic tonics, and particularly to the white oxyde of arsenic, which they give as in the case of sy- philis, and indeed of various other impurities of the blood, in the form of pills; mixing the arsenic, which, in Hindustanee, is sane hya, and in Arabic, shucc, with six times its weight of black pep- per into a mass with a little water; so that each pill may contain about two-thirds of a grain of arsenic and four grains of pepper, which is to be taken twice a-day. And this medicine is regarded almost as a specific antidote. It has no doubt proved often success- ful : and I have known various cases in our own country in which it has been found equally so in the form of the arsenical solution. In this quarter of the globe, however, Mr. Playfair has. of late years revived the use of one of the species of asclepias or swallow- wort. In Europe, the a. Vincetoxicum was formerly in high favour as an alterant and alexipharmic, and was often denominated contra- yerva Germanorum: but its virtues were not sufficient to support its character. The swallow-wort employed by Mr. Playfair is the a. gigantea, a native of the east, and appears, from an account late- ly published by Mr. Robinson,* to be possessed of more active and possibly more salutary, qualities. It is the nudar of Hindustan. The tonic found most useful by Dr. T. Heberden in Madeira was bark, which however, has not proved of equal success in other pla- ces or the hands of other practitioners; but he employed it in con- nexion with that course of external stimulants which has been found generally serviceable, and probably not a little contributed to its wonderful efficacy in the various cases he refers to, and particular- ly one of a confirmed and chronic attack. " I have," says he, " in this island experienced the use of the bark in four or five leprous patients with success. One had a confirmed elephantiasis; the oth- ers were only incipient; having no other symptoms than florid or livid tubercles in the face and in the limbs. The confirmed ele- phantiasis was attended with livid and scirrhous tubercles which had overspread the face and limbs ; the whole body was emaciated • the eye-brows inflated ; the hair of the eye-brows fallen off entirely '; the bones of the nose depressed ; the alae nasi tumefied, as likewise the lobes of the ears; with a suffusion on both eyes which had al- most deprived the patient of his sight. There was a want of sensa- * Medico-chirurg. Trans. Vol. 3^. GE. VII.-SP. I.] SANGUINEOUS FUNCTION. 573 tion in the extremities; and a loss of motion in the fingers and toes." For upwards of seven years Dr. Heberden had used every medi- cine he could think of to relieve this patient, but in vain. Antimo- nials and mercurials of almost every kind; neutral salts, the warm diaphoretics, as sassafras, and sarsaparilla, warm baths, and medicat- ed baths, were alike fruitless. On May 2, 1758, he made his pa- tient commence an electuary of powder of bark, with a third part bark of sassafras root, inspissated with syrup. And of this the quan- tity of a large nutmeg was ordered to be taken twice a-day. The patient at the same time had his arms and legs bathed with an em- brocation consisting of an ounce of lixivium of tartar and two drachms of spirit of sal ammoniac, intermixed with half a pint of proof spirit. By the latter end of May, the tubercles were conside- rably softened : by June 28, they were dispersed ; a red scurfy ef- florescence alone remaining behind, which in ten days lost its florid hue, and peeled off, leaving the cuticle sound and clean. " The pa- tient," says he, "gradually recovered the sensation in his legs and arms, and the use of his toes and fingers; the hair has grown again on his eye-brows ; and the only remainder of the distemper which I can perceive, is that the nose continues somewhat flatter from the depression of the bones. The suffusion is quite cured, and the pa- tient is ivaaexa *xt tv%{oosf* of a healthy skin and colour. SPECIES II. ELEPHANTIASIS ITALICA. Ktaltau Elephantiasis.

For a knowledge of this species we are almost exclusively indebted to the Italian physicians who have generally given it the name of pellagra or pelagra. The first writer upon the subject appears to have been Francis Frapolli, a physician of Milan, whose work, " In morbum vulgo Pelagram dictum," was published at Milan in 1771, and who expresses himself doubtful whether the disease, though not antecedently described, is not referred to occasionally by earlier writers, although he does not think that the pilarella, as the syphi- lis was called when it proved depilatory to the chin and eye-brows, * Med. Trans, ut supra. 574 HiEMATICA. [CL. 1II.-0R. IV. was the disease in question, notwithstanding this seems to have been an extensive opinion at the time. The next tract of any note upon the subject, was published at Venice in 1784, by G. M. d'OIeggio, under the title of « A Theoretical and Practical Treatise on the Dis- eases of Vernal Inoculation, commonly called Pellagra."* But the best account we have received of this complaint is from the pen of Dr. Jansen of Leyden which appeared in 1788, and asserts that it is endemic in the Milanese territory.t It is, in truth, common to both the Milanese and Venetian territories as well as to other dis- tricts widely differing in soil and temperature: and can scarcely, therefore, be referred to either of these sources. It is commonly ascribed, as we have observed above, to the heat of the sun's rays after the chill of winter, and is hence called mal del sole, which we have just seen, was the view taken of it by d'OIeggio; while by Odoardo it is attributed to a scrophulous habit,! and by Videmari and others, who have too much limited themselves to the nature of the eruption, to an impetiginous impurity.§ But none of these ex- planations seem to rest on any very solid foundation ; and, upon the whole, we have more reason for regarding it, as produced by the debilitating causes of hot, confined air, want of cleanliness and bad diet, operating in many cases upon a diathesis hereditarily tainted. It is found chiefly among the Milanese and Venetian peasantry, whose hovels are full of wretchedness, and rarely makes its appear-, ance till after the age of puberty. The first symptoms of the disease are general languor, listless- ness, gloom, feebleness, and stupor in the legs, and hence unsteady walking; vertigo and confusion of ideas. Domeier, another writer upon the subject, extends the stupor of the legs to the entire frame, and asserts that anaesthesia is a characteristic symptom of this species.|j But this assertion is not confirmed by the history of other patholo- gists : though the languor and inertness is often very great as well • as universal. These symptoms usually take place in the spring; and, as the summer approaches, a sense of tension, burning, and itching, is felt in every external organ except the head, followed by an inflation of the epidermis, and tubercles of, a shining red colour. After some days, the tubercles desquammate, and the skin appears at first red, but soon recovers its natural colour. As the summer, however, advances, every symptom commonly subsides, and the. strength returns with the winter. But if the symptoms do not thus subside., they become considerably exasperated and form a second stage of the * Tratto teoretico-practico delle malattie dell insolato di primavera volgari- mente dette della Pellagra. t De Pelagra morho in Mediolanensi Ducatu endemio.

The cutaneous affection now diminishes; but the nervous symptoms are greatly augmented. The vertigo increases; the patient is sad and loves solitude, and melancholy delirium alternates with furious mania. The taedium vita? is insupportable, and self-murder is a frequent consequence. Strambio remarks that those who labour under this disease have the greatest tendency to drown themselves, " as by an hallucina- tion," says he, " opposite to that of hydrophobia."* Coercion is at last necessary; and a diarrhoea, atrophy, or dropsy closes the dreadful scene, if the patient do not sink earlier from corporeal and mental exhaustion. The treatment need not essentially differ from that of the pre- ceding species. Pure air, habitual cleanliness, warm bathing, and a nutritious diet, with such tonics, whether vegetable or mineral, as best agree with the constitution, have proved most successful, where the disease has not advanced beyond the reach of recovery.

This species agrees in many of its symptoms with the Italic, and if is only worth while to notice the points in which they differ. Upon the whole, we may observe, that all the species coincide is being founded on an exhausted constitution, in the general character of the tubercles and in their fatal termination by dropsy, atrophy, or some other asthenic disease. The Arabic species attacks the face, the roots of the hair and the palate-bones before the remain- ing parts on which it preys are diseased, and the affection of the skin increases with the increase of the other symptoms. In the Italian species, the affection of the skin diminishes as the nervous and mental commotion augments. The pellagra also is distinguished * De Pellagra, Observationes. Ann. i. n. m.

In the Asturian species, the crustaceous tubercles are peculiarly painful; highly fetid, deeper furrowed with cracks, and more disgusting to the sight; attacking the head as well as other parts indiscriminately, and destroying the roots of the hair. The mind is less affected than in the last, and with melancholy and terror rather than with raving delirium. Tbis species constitutes the Asturian leprosy of Thiery, Vander- monde, and Sauvages; but genuine leprosy is not a constitutional complaint; and the present is its proper place. As the tubercles desquammate, the skin appears of a glossy leprous red, and the disease is hence called by the Spaniards Mai de la Rosa. The causes are extreme poverty and its attendants, filthy bad diet, and crowded unventilated rooms in the deep and swampy vallies of the country, almost impervious to the rays of the sun: and hence the medical treatment and general regimen recommended under the preceding species will afford the fairest promise of success here.

THE CONSTITUTION INFLAMMABLE IN CONSEQUENCE OF A LONG AND IMMODE- RATE USE OF SPIRITUOUS LIQUORS : THE COMBUSTION EASILY EXCITED OR SPONTANEOUS. In this wonderfuf^nalady, the art of medicine can be rarely of any avail; since the mischief is, in almost all instances, only to be discovered after a cessation of life, and the destruction of some part of the body by an actual flame, or fire, in many instances sponta- neously issuing from its surface. There may be some difficulty in giving credit to so marvellous a diathesis; yet examples of its existence and of its leading to a migratory and fatal combustion are so numerous and so well authenticated, and press upon us from so many different countries and eras, that it would be absurd to with- hold our assent. In almost every instance, the combustion seems to have taken place in females, advanced in life, and immoderately addicted to spirituous liquors.* In some cases the heat that has set them on fire appears to have originated in themselves; in others to have been communicated by a stove, or a candle : or a stroke of lightning ;t but in no case has the fire or flame hereby excited in the body been so powerful as essentially to injure the most combus- tible substances immediately adjoining it, as linen or woollen furni- ture. The body, in several instances, has been found actually burning, sometimes with an open flame flickering over it; and some- times with a smothered heat or fire without any open flame what- ever : while the application of water has occasionally seemed rather to quicken than impede the igneous progress. This is the more extraordinary, as the human body, in every other state we are acquainted with, whether of health or disease, is scarcely at all combustible of itself, and cannot be reduced to ashes without the assistance of a very large pile of faggots or other fuel, as universal experience in this very ancient mode of sepulture, and the history of martyrs, who have been condemned to the flames, abundantly testify. The event has usually taken place at night when the sufferer has been alone ; and has commonly been discovered by the fetid, pene- trating scent of sooty films which have spread to a considerable distance; the unhappy subject has, in every instance, been found dead, and more or less completely burnt up; the burnt parts * Bartholin, Act.

Pierre-Aime-Lair,* that these ac- counts at first appeared to me to be worthy of very little credit, but they are presented to the public as true by men whose veracity is unquestionable. Bianchini, Maffei, Rolli, Le Cat, Vicq d'Azyr, and other men distinguished by their learning, have offered certain testimony of the facts. Besides it is not more surprising to meet with such incineration than a discharge of saccharine urine, or an appearance of the bones softened to a state of jelly." Those who are desirous of pursuing this curious subject farther, and of entertaining themselves with the very extraordinary histories connected with it, as also of examining the various hypotheses by which they have been accounted for, may consult the Philosophical Transactions, Vols, xliii and xliv, the first of which contains numer- ous examples; as also a variety of foreign journals of established reputation, referred to, and cited in the running commentary to the author's volume of Nosology. We have not space to enter into these separate cases, though many of them are highly interesting; but in a general course of medical study, the phenomenon ought not to be passed by : it forms one of the most curious links in the long chain of morbid affections, and equally demands our attention as pathologists and physiologists.

The term purpura," observes Dr. Bateman, most correctly, " has been employed by different writers in so many ac- ceptations that some ambiguity would perhaps have been avoided by discarding it altogether; for some authors have used it as an ap- pellation for measles, others for scarlet-fever, for miliaria, strophu- * Journ. de Physique.

For as a term it is neither Greek nor Latin, nor any language whatever; but an intolerable barbarism, derived, as is commonly supposed, from the German compound schar-bocke literally " aggregate-pox," " cluster-pox;" but more likely from scharf-pocke, " violent, or vehement pox ;" or schorf- pocke, " scurf, or scurvy-pox," to which the inventor has endeavour- ed to give a sort of Latin termination. Independently of which scorbutus, as employed at present, only indicates a particular species of scurvy ; and could not therefore, without imprecision, be used in a generic signification. The sense here expressed by porphyra, runs, as nearly as possi- ble, parallel with the range assigned by Dr. Willan to purpura. " With Riverius and some other authors," says he, " I propose to express by the term purpura an efflorescence consisting of some dis- tinct, purple specks and patches, attended with general debility, but not always with fever." And again " cases of the purpura seem to have been studiously multiplied in periodical publications, and in medical or surgical miscellanies. I consider it under all the forms described as pertaining to the scurvy, though it is not always attended with sponginess of the gums, and a discharge of blood from them according to the definition of scorbutus in nosology."t Porphyra, in its present signification, is intended to include every description of petecchial eruption, and spontaneous ecchymosis not dependent on fever as their cause, in which case these affections are only symptomatic. The genus thus explained will associate under its banners the three following species: PETECCHIAL-SCURVY. LAND-SCURVY.

Pulicose or petecchial spots were at one time supposed to be, in every instance, the result of debilitating and putrid fever*. Riverius is, perhaps, the earliest author who distinguishes between simple petecchiae, and petecchial fevers. Vascular debility or relaxation is, however, the predisposing cause in both cases. They neces- sarily, indeed, accompany each other, and, wherever they exist in any considerable degree, they lay a foundation for those minute ex- travasations which constitute the present species; and which may take place either from occasional ruptures of the weakened coats of the minute subcutaneous blood-vessels, in consequence of their being incapable of resisting the impetus of the blood that flows through them; or from the mouths of many of them, which should give forth only the finer and limpid particles of the blood, yielding and allowing an exit to the red globules. Both these may follow upon atonic fevers; but the usual remote causes in the species before us, are severe labour with innutritious or spare diet, and especially with impure air; an impoverished state of the system from a sudden and profuse loss of blood; a sedentary and inactive life or some chronic and exhausting disease by which the general strength has been broken down. To these Riverius adds suppression of the catamenia, and a certain mild ebulliency of the blood in boyhood—levem quamdam sanguinis ebullitionem; a phrase apparently importing an excess of sanguineous temperament: from both which he tells us he has frequently seen the disorder originate. And he is confirmed in the last by a case hinted at by Dr. Perceval in his manuscript comment on the author's Nosology, in which he observes under the present species, that " in a young lady of a full habit, and florid complexion, if the skin of the face or neck were touched even slightly blood oozed from the pores." The disease seems also to be produced at times by some unknown cause; of which Cullen has given a striking instance in his Materia Medica. " The patient," says he, " was a woman who had lived very constantly upon vegetable aliment and had not been exposed, so far as could be judged, to any febrile or putrid contagion; and yet, without any feeling of any other disorder, was affected with numerous petecchiae over the whole surface of her body. After these had continued for some days without any symptoms of fever, she was affected with swelled and bleeding gums, with fetid breath GE. IX.-SP.

It is possible in this case that the brain may have lost its energy, and the blood become impoverished by too low a diet, though the history is not given with sufficient fulness to speak with much de- cision upon this point. The fever was evidently produced by the irritability of weakness, and necessarily ran into a typhous type from the same cause. The disease, as it commonly shows itself, under two forms, which may thus be described as varieties. x Pulicosa.

The flea-bite spots preceded Nettle-wheal Scurvy. by reddish, rounded and net- tle-sting wheals, but with- out the nettle-sting itching; fugacious and migratory. The first variety is not only produced by debility, but attended with languor and pains in the limbs, and chiefly affects women and children in consequence of their greater laxity of fibre. The second variety may possibly be accompanied with some kind of acrimony in the blood, and something more of a constitutional affection; for there is usually a loss of appetite, and an edematous swelling of the hands and ankles; while the spots are brighter at night and darker in the day; evidently proving great irritability in the capillaries, and especially towards the period of the natural evening paroxysm of fever, and great atony in the absorbents. This variety often continues for five or six weeks. Better diet, freedom from hard labour, pure air, sea-bathing, the mineral acids, and other tonic medicines, afford a pretty certain process of cure. SPECIES II.

The seat of the aneurism at length becomes distress- ingly painful from the increased circulation and swelling; the skin assumes a livid hue, and seems verging to a gangrenous state; a bloody serum oozes from it, and it often ulcerates : when the walls of the arterial sac, meeting with less support than hitherto, give way, the blood bursts forth with violence, and, if the artery be large, soon produces death by inanition. Such is the general course of encysted aneurisms that show them- selves externally; but as they often occur in vessels more deeply seated, we cannot so readily mark their progress, and can often only guess at their existence. They have been discovered, however, by particular symptoms in the chest, neck, head, forehead, temples, and back, as well as in every limb; and it is difficult to say which part is most subject to their appearance. In an early stage of the disease, it cannot easily be mistaken for any other; for the signs of a regular pulsation, absence of pain, and disappearance of the tumour on pressure, are sufficient to distinguish it. But when, in the progress of the complaint, the pulsation becomes almost imperceptible, and the tumour hard, it has been confounded with other encysted tumours, scrophulous swellings, and abscesses. The last is the most common error, and, by leading to an injudicious opening, has sometimes proved a fatal one.* The disease has occasionally been cured naturally by a deposit of coagula in the sac, which, as they have gradually increased, have gradually also filled up and obliterated the cavity of the sac. Mr. Hodgson has given a curious case of this kind in his treatise, " on the Diseases of Arteries and Veins." In such instances, however, it is probable that the disease is unconnected with an aneurismal diathesis, and is a result of some local cause. Pressure, under the same circumstances of local affection, has sometimes produced a like good effect. Dr. Albers of Bremen gives an instance of this even in an aneurism of the femoral artery^ It has commonly been said that the compress should never amount to more than an easy support to the weakened and enlarged organ :J and it is very probable that tight bandages, by impeding the circu- lation in the adjoining veins as well as arteries, have often proved injurious Dr. Perceval, however, in the manuscript comment with which he has enriched the author's volume of Nosology, has the following notice under the present head ; seeming to show that even a tight compress has at times been of the highest advantage ; and a like success is related by Acrel in an aneurism of the aorta.5 "In the rebellion of 1798, an officer received a wound from a bayonet which grazed the left carotid artery and produced a * Reinesius, Scliola Ictormn Medica, p. 321. t Trans, of Medico-Chirurg.

To describe the nature of the operation would be to travel into the province of surgery. 1 may, however, observe that in cases of necessity it has often been performed with full success, and even a perfect use of the affected limb, in trunks of a very large calibre. Mr., now Sir Astley Cooper, has given an account of two cases in which the operation was effected on the carotid artery. J he, first proved unsuccessful from the long standing and size of the sac, which pressed with perpetual irritation on the larynx and pharynx, exciting frequent hts ot coughing, and preventing deglutition. The second case terminated favourably ; but the tumour was smaller and of more recent growth. In the second variety or diffuse aneurism, the aneurism by infusion of M. Petit,§ the coats of the artery, instead of being dilated into a sac, are divided; and, the blood flowing at large into the cellular or other surrounding parts, the tumour is extensive and undefined. This is usually the result of external violence : the swelling often spreads to an unlimited range, and the progress towards a rupture of the integuments is more rapid than in the last. Here pressure is of no avail, and even mischievous; since it will more effectually obstruct the course of the blood in the surrounding veins, than in the divided artery: and the operation can rarely be dispensed with. Mr. B. Bell was fortunate enough to succeed in the case of a division * De Sed. et Caus. Ep. xvn. Art. 30, 31. t Vol. vn. p. 341. X Lond. Med. Journ.

The division was produced by an accidental and forcible entrance of a pair of long-pointed scissors into the hip. The patient fainted from loss of blood, and the wound on the surface was healed. The aneurism, however, continue!; fresh blood was perpetually poured forth; in six weeks, the tumour on the hip became enormous, the thigh was rigidly contracted, the bam recurvated, the leg shrunk, cold, and useless. On making an incision eight inches long, the blood issued in such torrents that the patient fainted, and was supposed to be dead or dying, but the artery could not be traced. At this critical moment Mr Bell ran the bistoury upwards and downwards, and at once made the wound two feet long: when thrusting his hand to the bottom of the tumour, he felt the blood still jutting warm from the artery, laid hold of it, and found it to be the posterior iliac cut through transversely. He tied it, and, loosely dressing the wound, left the patient on a bed in the opera- tion-room, as he was too much reduced to be removed. In seven months he was completely restored to health, and recovered the entire use of the affected leg. The third variety or varicose aneurism was first distinctly pointed out by Dr. Hunter, who characterized it by this name. It is produced by puncturing an artery through a vein, that lies immediately above it and upon it, as in blood-letting at the arm, so that the arterial blood flows from the arterial puncture, not through the cellular substance, but into the superincumbent vein through the corresponding venous puncture. In this case, the tumour is don- gated, taking the course of the vein, which is hereby distended and rendered varicose. Sometimes, indeed, where the venous commu- nications are frequent, all the adjoining veins participate in the distension, and are equally affected. The tumour, as in the first variety, disappears upon pressure ; and, as soon as the pressure is removed, the blood issues from the arterial puncture with a whizzing sound and a tremulous motion, rather than a distinct pulsation. This is the least dangerous of all the forms of aneurism, and that in which pressure may be applied most successfully. It has some- times produced a radical cure ; but in all instances so far succeeded as to render the operation unnecessary, provided the patient passes a quiet and unfatiguing life : for it has been known to exist twelve, twenty, and even thirty years, without any serious injury to the general health. The fourth variety is distinctly a constitutional affection, and usually of considerable distress and oppression. It is characterized by an obtuse intumescence and constant disquiet of the praecordia; with a sense of internal weight and pulsation increased on the smallest motion. It is the ca idiogmus of Galen and Sauvages; the aneurisma praecordiorum of many authors, and the polvpus cordis of others. The symptoms are usually found on dissection to proceed from an aneurismal enlargement of some part of the GE. X.-SP. I.] SANGUINEOUS FUNCTION. OMI substance of the heart, or the larger vessels in its immediate neighbourhood, sometimes accompanied with, and perhaps produced by, a polypous concretion; and sometimes without any such sub- stance whatever: and where the larger vessels are affected they are here, more than in any other variety, thickened and rendered rigid by irregular deposits of calcareous or ossific matter. It is found chiefly in persons of advanced age ; but whether in young or old is clearly a result of organic debility. It is well observed, indeed, by M. Rostan, that a dilatation and thickening of the walls of the heart, are not a consequence of great power or strength of constitution with energy of healthy action; but is generally caused by that state of the arteries which is an ordinary result of old age, in which they lose their natural elasticity, and become ossified, thick, inorganic tubes. This ossification affects the valves of the heart as well as the vessels in its neighbourhood, whence the heart is perpetually oppressed, and called upon for increased action : which increased action itself is another cause of increased thickening in the cardiac coats. The disease not unfrequently proceeds from a distinct cyst some- times found in the substance of the heart, as the right auricle, of which an example is given by Bartholin ;* or the left ventricle, as stated by Dr. Douglas ;t but more usually in the arch of the aorta. In many of these cases we can trace the cause; for the aneuris- mal artery is at times as contracted in the vicinity of the sac, as if it had been tied by a ligature. The aorta has, occasionally, in this manner been rendered altogether impervious, the circulation being continued by an enlargement of the anastomosing vessels.^ On this account, Morgagni ascribes the disease before us to a narrowness of the larger arteries as its common cause ; and hence explains why it is so frequently found among tailors, and other sedentary workmen § The medical treatment can be rarely more than remedial. Fa- tigue and great exertion must be sedulously avoided, together with keen mental excitement. The diet should be light, the meals and hours of rest regular; and the exercise should be that of a carriage. The bowels must be attended to; and, where the palpitation or other distress is peculiarly troublesome, it may sometimes be reliev- by camphor, volatile alkali, and tincture of hyoscyamus. We may observe, before quitting the subject, that the largest aneurisms have been those of this quarter, and particularly of the aorta, as there is here the greatest force of action.

In an enormous aneurism of the ab- dominal aorta, Morgagni mentions that the posterior wall of the artery itself was destroyed, the neigbouring parts supplying the place of a wall :| and in a like aneurism of the thoracic branch he found the bones in the vicinity broken and demolished by the force of its pressure.§ SPECIES II. EXANGIA VARIX. Qgnviv. SOFT, LIVID TUMOUR OF A VEIN. This disease is to veins what the true or encysted aneurism is te arteries. The coats of the veins are preternaturally dilated, and more in some parts than in others, so that a vein thus enlarged to any considerable extent often appears to be a chain of venous cysts; and as, contiguous veins often communicate, the enlargement is not unfrequently extended from one to another till the whole forms a plexus of varices, and every part seems ready to burst. In some instances, they are said to have bursted. This assertion, however, wants confirmation: but if it were true, we should be put into pos- session of a diffused as well as an encysted variety of veins, and the disease would make a still nearer approach to that of arteries. This affection mostly occurs in the veins of the lower extremities in consequence of their being the most dependent part. They of- ten arise spontaneously in persons of lax fibres ; but are far more frequently a consequence of undue fatigue, strains, cramps, or pres- sure. The most frequent cause is a pressure of the fetus in preg- nancy against the external iliac veins, in consequence of which the blood ascends with difficulty from all the veins below, which become distended and weakened by its accumulation. From strains or other causes however, varices have been occa- sionally traced in other large veins than those of the extremities. Thus Tozelli discovered it, after death, in the vena azygos ;|| and * Dissert, de stupendo Aneurysmate brachii, Sic. Jen. 1734. t Phil. Trans. N.287. X De Sed. et Caus. Morb.

Morgagni asserts that the spermatic varix appears more frequently on the left than on the right side, from the insertion of the spermatic vein into the emulgent.t The best remedy in all cases where it can be applied is a mode- rate, steady, and continued pressure : which, where the varix occurs in the legs, is easily accomplished by an elastic stocking, or, which is preferable, a circular bandage of fine elastic flannel. Dauter's plan of using cold water is also a very simple, and, where the varix is fresh, not unfrequently a very efficacious remedy :| but how far a solution of mineral acids or metallic salts may add to its virtue, as recommended by some practitioners, the author cannot affirm from his own practice. From their disfigurement and great discomfort, varices have some- times been attempted to be removed by a division between two ligatures, not widely different from the operation for the aneurism. The attempt has, in several instances, succeeded ; but it has more frequently failed, and a serious and far more extensive enlargement of the vein with varicose prominences has followed, similar to that which sometimes occurs in drawing blood from the arm ; of which till of late years no very intelligent explanation has been given, and which I shall therefore endeavour briefly to illustrate. This singular and painful line of swelling was at first supposed to arise from the prick of a nerve ; but the nerves liable to be wounded in bleeding are mostly small and unimportant; while others are often pricked and wounded in many of the common operations of surgery without any serious consequence whatever. The mischief has by other writers as Heister, Garengeot, and Haller, been ascribed to wounding a tendon or its aponeurosis; but unluckily for such phy- siologists, tendons in other places are often torn or wounded with very little inconvenience ; even the Achilles tendon, the largest in the body, is frequently broken, without any of the severe symptoms that sometimes arise from blood-letting. Besides which, the acci- dent from bleeding occurs as frequently when a person has been bled in a vein which has no tendon near it, as when there is reason to expect that a tendon may have been wounded. It happens as often that a swelled arm is the consequence of bleeding in the ce- phalic or cephalic-median vein, as of bleeding in the basilic or basi lie-median. Mr. J. Hunter was the first physiologist who ascertained the real cause of the mischief before us: and traced it to a general principle which he laid down as applicable to all internal cavities; namely^ *See Richter's Chirurgische Bibliothek in loco. t De Sed. et Caus. Morb. Ep. xi.m. Art. 34. J: Von dem auserlichen ortlkhen Gebranche des Kalten Wassers, &c. Leips. 1784. 600 HjEMATICA. [CL. HI.-OR. IV. that when injured or rendered otherwise imperfect, they are often apt to inflame at the injured part, and to have the inflammation spread rapidly over their whole extent, as I have already had an opportunity of observing under peritonitis, puerperal fever, and on various other occasions. He was first led to this view of the cause in the case of veins, from noticing what occasionally happens to horses. It is no uncommon thing for hostlers, out of an unnecessary or ill-judged care, to bleed these animals in the neck even when in perfect health : and in several instances of this kind Mr. Hunter had observed that the neck swelled, and the horse died; and, on ex- amining the nature of the disease by dissection, he found that the cavity of the vein was inflamed, and that the inflammation had spread along its internal surface to the chest, sometimes even to the heart itself. And he afterwards found a like effect produced in the veins of the human arm, where inflammation had succeeded to bleed- ing; and particularly ;n one case that occurred in St. George's hos- pital, being that of a man who died suddenly on the eighth day after having been bled in the basilic vein of the right arm, and having suffered from inflammation as a consequence. On dissecting the arm, he found.not only that the cavity of the vein had inflamed, but that the inflammation had extended from the puncture, which had been made by the lancet in blood-letting, as high as the axilla; proceeding also to some distance below the puncture. About the middle of the arm the vein had suppurated; and, from the ulcera- tion or absorption of parts which attends abscesses, the vein was di- vided into two ; and each extremity, like the internal surface of the abscess, was irregular and jagged. Mr. Hunter was disposed to think that the principal cause which produces the inflammation of a vein after bleeding is the want of a disposition to heal, arising either from its being exposed, or in con- sequence of the lips of the orifice in the skin not being properly brought together. And he hence strongly advises that the sides of an opened vein should at all times be made to approximate as accu- rately as possible, and that the orifice in the skin should be drawn to one side of that in the vein, so as to make the skin do the office of a valve to the venal opening.* There seems, however, in this explanation to be a something wanting; and I cannot avoid thinking, as in the case of puerperal fever, that there must be at the same time some peculiar local or constitutional irritability predisposing the injured part to run into an inflammatory action. It is also perfectly clear that the tingling and shooting pains which succeed venesection, are sometimes produced by a partial division of a nerve ; of which Mr. Sherwen of Enfield has given a very striking example in a case that only yielded to an entire division of the nerve by a transverse section above the orifice, after every other attempt had been tried in vain.t *' Edin.

SKIN MORE OR LEi5 BLUE J LIPS PURPLE ; GENERAL HEBETUDE, AND INAf T1VITV. This species is designed to express that singular appearance and diseased state of the entire system produced by a connate communi- cation of the two ventricles of the heart, and consequently an im- perfect discharge of the carbone of the blood at the lungs which constitute the proper organ of its elimination. From the Greek xvxm, or " blue," Dr. now Sir Alexander Crichton, in allusion to the colour of the skin by which it is peculiarly distinguished, has ele- gantly named it cyania, and the term has been adopted, as a specific appellation on the present occasion. Antecedently to birth, the lungs are of small comparative impor- tance to the functions of life and growth, and hence no more blood seems Jto circulate through them than is necessary for their de- velopement and health. The florid, or decarbonated blood, in- stead of being received from the lungs by the pulmonary veins, is received from the placenta by the venae cavee, and passes for the most part at once into the general circulation, chiefly by means of the foramen ovale by which the two ventricles commu- nicate, and partly by means of the ductus arteriosus, by which the pulmonary artery at this time anastomoses with the aorta; that por- tion of blood only which escapes through this canal flowing forward into the collapsed substance of the lungs; amounting probably to not more than a third or a fourth part of the whole. Immediately on birth, however, the plan of decarbonization is immediately changed. The fetal duct and foramen are closed, and the whole mass of blood flows black instead of florid from the venae cavae into the heart, and is sent by the pulmonary artery to the lungs for ventilation instead of to the placenta, in which organ, by the disengagement of the carbone with which it is loaded, and part- ly perhaps by the absorption of oxygene from the respired air (for .the subject is still open to controversy.) it acquires its perfect ela- boration and florid hue. It is hence obvious that if, in consequence of any aberration from the common law which regulates the wonderful change that thus takes place in the infantine heart and its attached vessels at the time of birth, either of these communications should remain open, Ihe venous or black-blood must wholly, or in a very considerable degree, be thrown back again into the general circulation instead of passing to ihe lungs: and the minute arteries on the surface. vol. it. 76 602 HiEMATICA. [CL. IH.-OR. IV. which give to the complexion its tinge, being filled with the same, the general hue must be changed from a florid to a blue or purple, more or less deep according as the pulmonary circulation is more or less impeded. It is this natural defect that constitutes the disease before us. In the varicose aneurism a small part of the florid or arterial blood flows through an accidental opening into the veins, but never in such a quantity as to disturb the economy of general health. In cyania a much larger, but variable proportion, of the black or ven- ous blood flows by a physical opening into the arteries; and usually with serious inconvenience to the general health, most commonly indeed with fatal effects. How far the ordinary disengagement of carbone from the blood may be dispensed with, or, in other words, to what extent these connate communications may remain, and the present disease take place without endangering the life, we have no exact means of ascertaining. Dissections have shown us that the foramen ovale has continued partially open to old age, without much or even any interference with the common functions of health :* but we may confidently assert that, whenever so large a portion of venous blood is thrown into the arterial circulation as to give a blue or purple tinge to the lips of the skin generally, all the functions will be performed fee- bly, and there is great danger that the infant will never reach the age of puberty. There may be living power enough in the blood to support the growth of the frame during the retired and quiet tenor of infancy, in which there are no sudden exertions or calls for a more than ordinary expenditure of sensorial power: and hence, it is no un- common'thing for a child to survive the first three or four years of life with a skin completely blue, and consequently with a full proof that the foramen ovale, or the ductus arteriosus, or both, are open to a very considerable extent, and that not more than perhaps a third or fourth part of the general current of the blood passes into the lungs and undergoes the process of ventilation. But as soon as a more active period of life commences, and the child is trusted to his feet, and engages, or should engage, in the pursuits or even amusements of boyhood, with all its physical and moral excitements, the living power is not adequate to the demands made upon it, and he sinks beneath their oppression, and generally expires in a fainting fit. There is commonly, moreover, through the short and pitiable term of his existence the clearest proof of general torpitude and deficient energy; every exertion is a trouble, every stimulus produces fa- tigue : the muscles enlarge, but they want vigour and elasticity : and, so far as I have seen, the faculties of the mind are equally blunted. The celebrated blue-boy described by Dr. Sandifort, advanced farth- er towards an adult age than is by any means common. Here the aorta took its rise from both ventricles; the pulmonary artery was * Geschichte einer chirurg. Privatgesellschaft in Kopenhagen.—Bertholin. Anal. Reform. Lib. li. cap. S. GE. X.-SP. III.] SANGUINEOUS FUNCTION. 603 scarcely pervious to a small probe, and the difficulty of passing the probe from the heart to the lungs was greater than in the contrary direction. The patient was affected with an asthma from his second year and terminated the miserable series of his sufferings in his thirteenth* In the case of a young female related by Morgagni the term of life was protracted to the sixteenth year; but there ap- pears to have been a somewhat freer communication with the lungs, notwithstanding that the foramen ovale was open wide enough to admit the little finger. The patient, however, was sickly from her birth, and laboured under great general debility; her respiration was difficult, and her whole skin of a livid colour.! Life, however, for a short time has been maintained under still more complicated misformations of the heart, and adjoining arteries. Mr. Standert gives the case of a blue-child that lived ten days, in which the two ventricles communicated, there was no pulmonary artery, but its place was supplied by an artery that branched off to the lungs from the aorta in the situation of the ductus arteriosus, the blood from which was returned by four small pulmonary veins. J And in Dr. Baillie's Morbid Anatomy is a still more complicated case of a child that lived about two months, in which the two ven- tricles communicated, but seemed to change their respective offices;. the aorta arising from the right ventricle, and the pulmonary artery from the left. The arterious duct was also open.§ In distressing affections of this kind the art of medicine is un- available ; and all we can advise is perfect tranquillity, a light diet, and attention to the state of the bowels.

And even in this last view they have rarely preserved their gradations with any thing like an uni- form consent; the whole of them sometimes expressing the highest and sometimes an inferior degree of the malady they equally im- port. For reasons stated in the volume of Nosology, the first of these terms is here employed in a generic sense, and the two latter as subdivisions or species included under it; sphacelus importing mor- tification as it occurs in its ordinary form, with lividity, vesication, ulceration, and fetor; and necrosis that insendbility and shrivelling of the flesh which occasionally occurs in paralytic limbs. The genus will also extend to two other species; as the gangrene which commences in a bone and is usually called a caries; and that pecu- liar form of the disease which begins insensibly in the extremities, and spreads without fever in an ascending direction till the affected limbs drop off in succession. All these will therefore be treated of in the following order: MORTIFICATION. MILDEW-MORTIFICATIOX. DRY GANGRENE. C-tRIES. SPECIES I. GANGRAENA SPHACELUS. ^Hovttft'Ccitfon. THE DEAD PART SOFT, MOIST, CORRUPT, AND HIGHLY OFFENSIVE. Mortification is a disease of debility; it is a total torpitude or in- sensibility of an organ while in the possession of its ordinary fluids and general structure, how much soever that structure may be in- jured, produced by a discontinuance of the living principle that has hitherto actuated it; in consequence of which the laws of animal chemistry, thus far held in subjection by the superior sway of the liv- ing power, acquire an ascendancy, a play of chemical affinities takes place, and putrefaction, or a decomposition of the organized sub-' stance, and a restoration of its constituent parts to their elementary forms, necessarily ensues. This total debility, insensibility, or torpitude, may be produced by too much or too little action or excitement; for the vital flame may be supplied so rapidly as to destroy by its own violence, or there may be no supply whatever. And we are hence furnished with the two following varieties of the disease : 1.

The ordinary causes of the first are fever, inflammation, local vio- lence, or severe cold. Those of the second are old age, impure air, scanty or innutritious food; and, for the same reason, as Sir Clifton Wintringham has observed, ossification in the arteries of the part affected; which is, indeed, chiefly a consequence of old age. Where mortification ensues, upon a severe contusion or other m- iurv, in a person of florid and vigorous health, and in the prime ot life, we have an example of the first variety. There is in this case high inflammatory action, great heat, swelling, and pulsation ; the vessels are supplied with a superabundance of living power, (the excitability of the Brunonians,) and are in consequence excit- ed beyond their strength; they are hence worn out by the impetu- osity of the toil, lose their tone, and become torpid and insensible from the vehemence of their own exertion. _ The second variety may be illustrated by the mortification which so frequently takes place in the extremities of persons already ex- hausted by hard labour, intemperance, or advanced years, and whose extremities are bloated and anasarcous. Instead of a superabundant supply of living power there is, in this case, little or no power whatever ; for the sensorial fluid is secreted so sparingly as to be almost incapable of reaching the extremities, and particularly the lower limbs : the muscular fibres of which, however, are in them- selves so irritable that a more than ordinary excitement is scarcely capable of rousing them; and hence they yield to the process of putrefaction from a cause the very reverse of what operates in the preceding case. Under the first form, there is more pain and fever, as there is more sensibility and violence, than under the second ; and, on this account, the destructive march is more rapid; but with these ex- ceptions the symptoms, which are the ordinary ones of putrefaction, are the same. The colour of the skin changes to a dark red, or livid hue; the cuticle is separated from the true skin by the inter- position of an ichorous fluid contained in vesicles, or bullae, or dif- fused generally; it bursts by degrees; and the subjacent integuments are cold, black, flaccid, sloughy, and insensible ; sanious or bloody discharge of a most offensive smell. If the sphacelus meet with no check from art or nature it spreads rapidly in every direction, particularly under the first variety ; and more especially when aided by an impure or unventilated atmos- phere, of which the hospital gangrene, as it is called, furnishes us with a fearful example. " I have seen," says Dr. Hennen, "■ the external ear and the palpebral destroyed in this manner as if in a series of concentric circles. Even upon surfaces barely contiguous, as the fingers and toes, it generally spread in a similar way; so that * Comment, u' n.orbis (piibut-'ifirn, Av. I'.'o. 54. 606 HAMATICA. [CL. III.-OR. IT. the sore which might have been on the middle finger or toe, and confined entirely to it at the morning dressing, by night engaged the adjoining sound ones, and in less than twelve hours more em- braced the whole foot or hand. The gangrene still advancing, fresh sloughs were rapidly formed, the increasing cup-like cavity was filled up, and overtopped by them, and the erysipelatous livor and vesication of the surrounding skin gained ground, while chains of inflamed lymphatics could be traced from the sores to the ad- joining glands; thus exciting inflammation and suppuration which often furnished a new nidus for gangrene. The face of the sufferer assumed a ghastly anxious appearance; his eyes became haggard, and deeply tinged with bile ; his tongue loaded with a brown or blackish fur, his appetite entirely failed him, and his pulse was con- siderably sunk in strength and proportionably accelerated. During this state, Dr. Hennen adds, that the bravest soldiers be- trayed " the greatest imaginable impatience of pain and depression of spirits. Men who had borne amputation without a groan shrunk at the washing of their sores, and shuddered at the sight of a dead comrade ; or even on hearing the report of his death, predicted their own dissolution, and sunk into sullen despair. The third and last stage was now fast approaching. The surface of the sore was covered with a bloody oozing; and, on lifting up the edge of the flabby slough, the probe was tinged with dark-coloured grumous blood, with which also its track became immediately filled: re- peated and copious venous bleedings now came on which rapidly sunk the patient: the sloughs, whether falling off spontaneously, or detached by art, were quickly succeeded by others, and discovered, on their removal, small thickly studded specks of arterial blood. At length an artery sprung, which, in the attempt to secure it, most probably burst under the ligature : the tourniquet or other pressure, was now applied, but in vain ; for while it checked the bleeding, it accelerated the death of the limb, which became frightfully swelled and horribly fetid. Incessant retchings soon came on, and, with cauma, involuntary stools, and hiccough, closed the scene."* In this extreme form of gangrene a septic principle appears to be developed, very highly acrimonious and capable of propagating the same disease by contagion. For not only " upon surfaces bare- ly contiguous" was it found to obtain an existence, but " the skin of other persons, although perfectly sound, which had been touched with a sponge employed in washing the gangrenous sores, ulcerated, and soon became itself a slough. This, adds Dr. Hennen, was often observable among the orderlies and nurses." The treatment belongs rather to the department of surgery than of medicine. It is obvious, however, that under the above two va- rieties it must be greatly varied to meet the variety of cause and constitution. Where an inflammatory diathesis is present, evacu- ants of every kind must be had recourse to without sparing, as ve- * Principles of Military Surgery, 2d. Edit. 8vo. Edinb. 1310. GE. XI.-SP.

But where, on the contrary, the mortification is that of atony, the warmest tonics and stimulants are demanded, both locally and generally, from the first. If the limb be frost-bitten, and there be danger of mortification from this source, a plan of treatment will be requisite different from both the above, the advantage of which is known to every one, though the principle upon which it acts has never been clearly ex- plained. The torpitude or insensibility of the part affected is, in this case, evidently produced by the exhausting power of the cold, which de- stroys or extinguishes the irritable and sensorial principle as rapidly as it is supplied. Putrefaction, however, or a decomposition of the organic structure, does not readily ensue because the auxiliaries of this change, and which are absolutely necessary to its production, such as heat, air, and moisture, are not present: for as the parts become frozen they lose their moisture or fluidity, and as there is no breach of surface, there is no communication with the exter- nal air. When a limb in this state is suddenly brought before the fire it becomes gangrenous almost instantly; for by this mean pu- trefaction obtains possession of these auxiliaries; and, in its process, gains the start of the remedial or restorative power of nature. And hence it is well known that the worst thing that can be done to a frozen limb is to bring it into such a situation. On the contrary, if we give time to this restorative power to exert itself while we prevent the process of putrefaction from taking place, by keeping the limb very nearly in the same condition of freezing, or rather' by raising it out of this condition by slow and imperceptible decrees we shall have the best chance of recovering it to life: since we hereby afford an opportunity for the warm and circulating blood and he active principle of irritability to push forward once more into he vessels of the frozen structure, which, however, weakened and ^v^Xr^ b— imposed, and to reSet The advantage of plunging a frozen limb, first into ice-water in this nTW3rdS T Water.raised J»t ^ove the freezing poinT,tid in this manner advancing it gradually to a common temperature i of general notoriety; and it is this plan which forms the usua treatment.

Tins is the necrosis ustilaginea of Sauvages, the specific epithet be- ing derived from the cause to which it has commonly been ascribed, and from which, in various cases, it seems to take its rise; I mean the use of grain vitiated or poisoned by the growth of parasitic plants in the interior of the culm or straw, chiefly the " ustilago," u blight or mildew ;" whence the name of " mildew-mortifications" among ourselves, as that of Ergot, or spur, among the French, from the resemblance which the mildewed or blighted corn bears to the spur of a cock, in Latin clavus, which is the name borne by this par- asitic plant in the language of many botanists. Grain thus injured by some fungus or other has been found, when employed as food, productive of two dreadful diseases ; to both of which, indeed, the French have given the name of Ergot, as occa- sioned by a common cause; as they have also that of mal des ardent from the burning internal heat which is felt in either case. The one of these disorders is a typhous fever, with the general charac- ter of pestis, or what Sauvages calls erysipelas pestilens, which is synonymous with the third variety of pestis in the present work: the other is the migratory gangrene before- us, which commences, without fever, in the hands and feet, with a sense of numbness^and external coldness, a dusky or livid cuticle, great debility of mind and body, often violent spasmodic contractions :* and spreads rapid- ly over the system, till the fingers, arms, nose, legs, or thighs are affected, and some of them drop off spontaneously. Mr. Pott has described this species, with a few slight varieties of symptoms, at full length, but without appearing to satisfy himself with any particular cause. " Beginning," says he, " at the extremi- ty of one or more of the small toes, in more or less time it passes on to the foot and ankle, and sometimes to a part of the leg, and, in spite of all the aid of physic and surgery, most commonly destroys the patient. It is very unlike to the mortification from inflamma- lion, to that from external cold, from ligature or bandage; or to that which proceeds from any known and visible cause, and this as * Morgc^i ;.

In some few instances, it makes its appearance with little or no pain ; but, in by much the majority of these cases, the patients feel great uneasiness through the wbole foot and joint of the ankle, particularly in the night, even before these parts show any mark of distemper, or before there is any other than a small discoloured spot on the end of one of the little toes.—Each sex is liable to it: but for one female in whom I have met with it, I think 1 may say that 1 have seen it in at least twenty males. 1 think, also, that I have much more often found in the rich and voluptuous, than in the labouring poor; more often in great eaters, than free drinkers. It frequently happens to persons ad- vanced in life, but is by no means peculiar to old age. It is not in general preceded or accompailied by apparent distemperature of either of the part or of the habit. In its severer attacks, however, the constitution seems to be ge- nerally contaminated, the mind and body become equally debili- tated, there is great irritability, and a tendency to convulsive ac- tion. According to every statement this singular disease seems to be connected with a diseased state of the digestive organs, from excess of liviDg, deleterious food, or some other cause in connection with great nervous debility :* and the tendency to gangrene proceeds rather from a deficiency of sensorial power, rather from any mor- bid condition of the circulating system, whether atonic or entonic. And, hence, we find it best relieved by free doses of opium, in con- junction with a generous and even stimulant diet. Bark is of no avail, and the local use of spiritous fomentations and cataplasms, warm pun- gent oils and balsams, of as little. Mr. Pott tried them in every form, but without the smallest success : and at length, employing no other topical application than smooth soft unirritating poultices, he confin- ed himself to the use of opium alone, of which he sometimes gave a grain every three hours. And under the influence of this medicine the progress of the gangrene has often become checked in a few days, and a line of separation distinctly marked; soon after which, the mortified parts have sloughed away, the diseased' bone dropped spontaneously from the affected joint, healthy granulations succeeoed, and in due time a cure has been effected.

THE DEAD PART DRV, SHRIVELLED, HARD, AND DUSKY. This singular species of gangrene seems to proceed from a maras- mus or atrophy of the affected.limb, in consequence of which, as in the atrophy of the body at large, the animal oil, flesh, and fluids al- so are gradually absorbed, and the limb becomes emaciated and withered. During the progress of this change, it necessarily grows feebler and more torpid, till at length it is no longer capable of be- ing stimulated by the sensorial fluid, and its different parts turn dead and rigid. In palsied limbs, a termination of this kind is by no means uncommon. In some instances of this affection, the blood-vessels have col- lapsed, perhaps become obliterated without a retention of any of the constituent principles of the circulating fluid, and consequently the withered limb has preserved something of the natural colour of the skin. In others, the red particles of the blood, changed, as in the veins, to a dark or livid hue, have, to a certain degree, remained in the vessels and given to the limb a purple or variegated dye. And hence the species has laid a foundation for the two following varieties : x Albida. Retaining something of the natural colour of White gangrene. the skin. Z Discolor. The natural colour changed to livid, or a Black gangrene. mixture of hues. It has never hitherto been satisfactorily explained how it happens that under this kind of mortification, or death, the parts should not, as in the preceding species, fall a prey to putrefaction. Per- haps the following remarks may afford some clue to this singular exception. We have already had occasion to observe, under the first species, that a frost-bitten limb does not putrefy so long as it continues fro- zen, because the accessaries or co-operative powers of putrefaction, without which this process cannot take place, are not present, such as warmth, moisture, and a free influx of air. Now none of these are present in the species before us, for the limb is cold, completely emptied of its fluids, and impervious to atmospheric influence : and consequently there are the same obstructions to putrefaction in dry gangrene, as in a limb killed by the biting power of frost. So in the burning sands of Egypt, a buried corpse is often found, if dug up a month or two after interment, with as few marks of pu- GE. XI.—SP. HI.] SANGUINEOUS FUNCTION. 611 trefaction. I have said that warmth is a necessary auxiliary, but it must be warmth to a certain degree only : for if it exceed this, all the interior fluids will by the heat itself be raised towards the surface, and pass off rapidly in the form of vapour; in consequence of which, the animal substance whence they issue will be as destitute of mois- ture as if it were frozen, and hence as incapable of putrefying. Now this is the case with a body interred in the sultry sands of the Delta : all its fluids are so highly rarefied as to evaporate, and be drunk up by the bibulous soil by which it is surrounded before any organic decomposition takes place : and hence the buried corpse, instead of crumbling into dust is converted into a kind of natural mummy, some parts of which exhibit proofs of that waxy fat to which the French chemists have given the name of adipocire : but no part of which undergoes the decomposition of putrefaction. I do not mean that this is always the case, but that it has occurred in a variety of instances, where the antiseptic incidents have been pecu- liarly favourable to such an effect. Dr. Alix of Altenburg, gives a singular example of the second va- riety of this species, in a man of seventy-two years cf age, which commenced, contrary to its usual course, with inflammatory symp- toms. The back of the left hand was attended with heat, swelling, and pain, accompanied with thirst, a smart fever, and delirium. At the time Dr. Alix saw him, a -blackness had spread over ail the hand, and part of the fore-arm, which were of a gangrenous hue, but without pain and as hard as wood. The pulse was small, and the spirits low. Amputation was advised, but not agreed to. About six months afterwards he saw the patient again accidentally : the gangrene had spread up to the elbow-joint, the limb was still with- out pain, the pulse was better, and there was no want of appetite. As it was not supposed the man could live long, no farther inquiries were made about him till a full year afterwards, when he was found to be as firm and stout as ever, although he at this time laboured under a tertian intermittent, and had lost one of his eyes. The gangrene had spread over the whole arm up to the shoulder-joint: the limb still continued hard, and as black as smoked meat; but did not emit any cadaverous smell. In about a month from this time, the arm dropped off spontaneously without the least hemorrhage : the exposed surface of the shoulder dried without any discharge whatever, and the old man, at the time of publishing the case, four years afterwards, was in the enjoyment of a very good share of health.* In this instance, the small proportion of living power which conti- nued after the inflammation had subsided, preserved the limb from putrefaction ; aided by the hard and shrunk condition into which it had fallen from absorption, and a paralysis of the secernents. Where there is no inflammation topical stimulants, and especially of the oleaginous kind, as camphorated oils and warm balsams, with * Matthrci Francisci Alix, Med. r-t Chir. Doct. Sic.

Repeated blisterings and setons have also proved serviceable, and the voltaic trough still more so, in conjunc- tion with a nutritive and generous diet. But when the gangrene has established itself, medical skill can do nothing more than look on and lament its want of power. SPECIES IV. GANGR.ENA CARIES. tiTartrs. THE DEAD PART ORIGINATING IN A PORTION OF THE SUBJACENT BONE : PAIN DEEP-SEATED, SUPERJACENT INTEGUMENTS FLACCID AND DISCO- LOURED. Bones, cartilages, and membranes in their nascent state are nearly alike; being formed in the same manner, and exhibiting the same kind of structure. Membrane is an. expansion of gelatine richly mapped with vessels and nerves, and containing a small proportion of albumen to give it a requisite degree of firmness; cartilage is membrane with a larger proportion of albumen to give it a still greater degree of firmness; and bone is cartilage hardened by an absorption and deposit of lime through the whole of its make. And hence bones, notwithstanding their solidity, possess the same living power and are subject to the same diseases as the soft parts. Like the soft parts, therefore, they are subject to a cessation or loss of this living principle, and the disease is, in this case, usually called a caries, a Latin term, probably derived from the Hebrew rH3 " ^ dig into, penetrate, or erode," "• to scoop, or hollow out." It may originate in a bone itself, which constitutes a proper caries; or it may be communicated from a superjacent ulceration, in which form it is more correctly denominated a carious ulcer. The history and treatment of caries belong rather to the depart- ment of surgery than of medicine ; and are to be learnt from writers on this branch of the profession who have expressly treated of it; among whom may especially be mentioned Wiseman,* Petit,t and Monro,J particularly the last, as his learned and ingenious essay on this subject ought to engage the attention of every one.

The cautery thus prepared and applied, has been frequently found the most effectual as well as the shortest means of extirpating can- cerous schirrosities about the lips, and other parts of the surface. And it is peculiarly calculated for radically destroying many of those irregular and spongy excrescences which, from their readiness to bleed freely, have been distinguished by the name of fungus hema- TODES. The nature and origin of these parasitic substances have not been very satisfactorily explained. By some writers, and especially by M. Roux, they are regarded as soft and fungous cancers, but they seem to be without any of the pathognomic signs by which cancers are distinguished. They are not known to be hereditary, nor to become scirrhous in any stage, nor do they chiefly affect a glandular situation. They are found in every part of the body, appearing at first like a small sarcomatous tumour, with a soft or medullary feel: the tumour enlarges, and secretes an acrimonious fluid which con- taminates the parts adjoining, whether gland, muscle, cellular mem- brane or periosteum, and converts them into its own nature. At the same time it erodes the skin and soon sprouts above it in a loose, luxuriant and cauliflower form, of a dark red, or purple hue, loaded with blood-vessels, and bleeding profusely upon a slight puncture or even pressure. This singular fungus has often sprung up in in- ternal cavities, as the ball of the eye, the lungs, the testicles and the uterus: and has occasionally appeared in the breast, the spleen, and the liver. In these situations it is apt to ravage without re- straint, and there is great difficulty in destroying it without destroy- ing the organ from which it issues. But wherever the hand can follow them they are often repressed, and have been sometimes ex- tirpated by caustics, and particularly by being sprinkled with a mixture of powder of arsenic and opium ; and sometimes, where it is seated on a narrow peduncle, by a ligature. The actual cautery, however, wherever it can be applied, seems to afford the quickest and most effectual cure, and in the peduncular variety offers the best means of preventing a profuse hemorrhage, by being applied to the stump after the body of the tumour has been removed by the knife.

We have already seen, that inflammations of every kind propagate themselves by continuous sympathy; and hence one cause of the spread of those that are ulcerative. But ulcerative inflammations do not spread equally; for those parts are most subject to their ac- tion, and consequently give way soonest where the living principle is weakest, or the structure is most loose and cavernous. And hence 1 GE. XII.-SP. III.] SANGUINEOUS FUNCTION. 619 a more frequent origin of hollows and sinuses in the cellular sub- stance, particularly in the more dependent parts, as about the rec- tum, and the urethra. These sinuses or hollows are soon filled with lymph or some other fluid, and this fluid, in a vitiated state of the ulcer, soon becomes acrimonious and erosive; and we have hence a chemical cause of extension or elongation added to that of a structural. And to this cause we are chiefly to ascribe the origin of the fistula lachrymalis. When these sinuosities are first formed or scooped out, their walls ' are soft, irritable, and of the common cellular web; but when they have remained for a considerable period of time they become cal- lous and insensible : forming the two following varieties noticed in the volume of Nosology. x Recens. The channel fresh and yielding. Recent Sinus. C Fistulosum. The channel chronic and indurated. Fistulous or Pipy-sinus. The form assumed by a sinus is determined by the course of the probe ; its capacity by the quantity of water or any other fluid it will contain when injected by a syringe. Three modes of cure have been attempted, that of incarnation or filling up the hollow by sound granulations issuing from the bottom; that of coalition or an union of the walls of the sinus, and that of destroying it by an opening down its entire length. The first is sometimes accomplished by warm detergent balsams or lotions where the sinus is shallow. The second is more usually had re- course to where it is deeper; and attempted first by irritant and even erosive injections, so as to excite a new inflammation down the whole course of the canal; and afterwards by pressure applied at first to its lowest part, and advanced gradually to its mouth; or, which is better, by a seton passed from the orifice of the ulcer to the utmost depth of the sinus, leaving here an opening sufficiently large for the escape of whatever matter might otherwise collect and become stagnant. The third mode of cure is effected by the knife, and where unaccompanied with danger or inconvenience from the vicinity of large blood-vessels or nerves, is by far the speediest aud most decisive of the whole.

A valuable practicable paper upon this disease is to be found in the Philosophical Transactions* addressed to the Royal Society By M. Daviel, surgeon to Lewis XV. of France ; who describes it as a cancer, to which, indeed, from its tendency to ramify, and the viru- lence of its discharge it has some resemblance; and whence Sauva- ges denominates it cancer Lupus. It commences in the subjacent periosteum or perichondrium from a diseased condition of the or- gan; at first assumes externally the form of a tubercule or wart; and though found over the body generally, is most common to the eje-lids, nostrils, cheeks, and other parts of the face. At is highly irritable ; and when the tubercle has acquired the size of a fig or filbert, it ulcerates the cuticle, shows a callous edge, and spreads with a most offensive ichor in every direction: often throwing forth fungous excrescences from the bottom. Occasionally before it opens externally, from the acrimony se- creted below, an herpetic vesication is formed on the surface. If partially extirpated, it grows again with rapidity and to a grea- ter extent; caustics always exacerbate it; and the only radical cure consists in dissecting the diseased part, and removing the whole of the periosteous or cartilaginous base as far as it appears to be af- fected. SPECIES V. ULCUS CARIOSUM. <£arious Wllttv. THE ULCER EXTENDING INTO THE SUBSTANCE OF THE SUBJACENT BONE. When a portion of a bone is killed by an ulcerative process com- mencing in itself, it forms as we have already observed, a caries properly so called. When it is destroyed by the spread of a sore commencing in the integuments or muscles above it, the disease is called a carious ulcer. And when the ulceration extends to the medulla of the bone it is often denominated an arthrocace. Upon this subject, however, it is not necessary to enlarge in the present place; as we have already discussed the general nature and the ordinary forms of ulceration under the first species of the Genus before us, and the mode by which the death and separation of one portion of* bone from another are effected, under the fourth species of the preceding Genus. * Vol. XLix, year 1755.
