FIRST SERIES. 1834-5. LECTURE I. GENERAL OBSERVATIONS. Gentlemen, As it is usual, at the commencement of a course of clinical in- struction, to devote the first lecture to a consideration of some general topics connected with the line of studies most proper to be pursued by those who wish to attain eminence; I have, in com- pliance with this custom, thought it right to lay before you some observations on the proper mode of studying physiology and morbid anatomy, with a view of showing how best to derive ad- vantages from these accessory but necessary sciences, sciences which, according to the manner in which they have been cultivated, have, at different periods, retarded or advanced that most important of all branches of professional knowledge, practical medicine. It is quite evident, that a knowledge of the functions and structure of the body in health is essential to him who undertakes the treatment of disease, and hence physiology has always occupied the atten- tion of physicians. Physiology, however, may be studied in very different ways, and with very different objects; and, until lately, all those who were engaged in the cultivation of this fascinating science, not contented with observing the state of the different parts and tissues during health, the nature and quality of the secretions, the mechanism and operation of the different organs, sought to ascend from a knowledge of effects to an investigation of causes, and, after they had classified the more obvious phenomena of living bodies, endeavoured to ascertain, if not the very principle of life, at least those motions and causes of motion which result imme- diately from the action of the living principle. Having thus, as they conceived, obtained a more accurate knowledge of the condi- tions of health, they proceeded to form general explanations of the 2 GRAVES’S CLINICAL LECTURES. causes of disease, and frame general rules for their removal. This method, apparently so philosophical, and possessing so many attrac- tions from the generality and simplicity of its application, has, more than any other circumstance, contributed to retard the pro- gress of medicine. Gentlemen, this is not only an ancient, it is also a modern evil. We live among systems. It is true, that the practice, founded on the mechanical, mathematical, chemical, and humoral physiologies, has been long since abandoned ; but the de- structive system of Brown has not long quitted the stage, where its place is occupied on the continent by those of Broussais and Rasori, and in Great Britain by the system which derives all diseases from derangement of the digestive functions, or from inflammation. Physiology legitimately embraces, not the study of vital actions, but merely aims at ascertaining and arranging their effects. The important facts which its study discloses, are perhaps infinite in number. As long as we confine ourselves to these we advance at every step, and all is clear and intelligible; but the moment we attempt to enquire into the causes and modes of vital action, we begin to retrograde, and all becomes hypothesis and confusion. Thus, an examination of the organ of sight discovers a wonderful and beautiful optical arrangement, calculated to form on the retina a picture of external objects, exact both in its colouring and out- line. The physiologist, examining with attention the different parts of the eye, and the laws of their respective refractions, inves- tigates the means by which distinct vision is secured at different distances ; he compares the human eye and its appendages with that of animals which live in water, those which soar into the highest regions of the atmosphere, and those which burrow under ground. He considers the eye of the mole, feeble but protected against injuries likely to be encountered in carrying on its subter- raneous works • of the eagle who, poised high in mid-air, selects its victim from the distant pasture ; of the fly, whose microscopic organ, with a range of vision scarcely exceeding the limits of con- tact, distinguishes objects the most minute ; and in all he finds variations in the optical instrument at once curious and intelligible. But when he endeavours to advance further in his enquiry, and tries to explain how an image, painted on the retina, produces vision, whether by the means of undulations arising from the rays of light, and propagated along the optic nerve to the brain, or whether because the retina is a nervous expansion, highly organ- ised and framed, so as to feel the coloured image painted on it, he is at once arrested in his progress by the barrier which is every where interposed between physical and vital actions, between the mechanism of the organs of sense and the mode in which they pro- duce ideas between body and mind. But has he, therefore, gained no real knowledge applicable to practical purposes, or has his time been merely spent in a pleasing but useless study? By no means;—being acquainted with the mechanism and arrangement of the optical instrument, he is often enabled to remedy its accidental derangement. By means of a con- GENERAL OBSERVATIONS. 3 cave glass he corrects a too speedy, by a convex a too tardy, con- centration of the rays of light. When the crystalline lens become opaque, his knowledge of its connections, nature, and position, enables him either to remove it altogether, or to displace it from the axis of vision, or to promote its absorption, and, in order to effect the latter purpose, he mechanically irritates it, knowing by experience that, after such an irritation, the process of absorption commences, although he is quite ignorant of the connection between mechanical irritation and this vital process. He who enquires into the physiology of the brain and spinal marrow can never dis- cover the nature of nervous influence, or the manner in which pressure on these organs destroys, or irritation deranges, the mo- tions of the voluntary muscles, and yet the entire treatment of cerebral or spinal diseases, whether spontaneous or from the effects of injury, is grounded on a knowledge of this physical fact; with- out it we could not estimate the value or effects of morbid changes in the brain or spinal marrow. On this reposes the rationale of the treatment of all convulsive, paralytic, and apoplectic affections. Although we know not the manner in which the eighth pair of nerves superintends the respiratory process, although we under- stand not how the phrenic nerve influences the motion of the dia- phragm, yet a knowledge of these facts led to a relief of spasmodic asthma, and to the recovery of persons apparently asphyxiated, by means of the galvanic stimulus passed along the course of these nerves. Knowing that some of the nerves, distributed to the face, are destined for sensation, while others serve for muscular motion, in cases of tic douloureux we divide the sentient and not the mo- tive nerves. In these, and a thousand other instances, physical physiology supplies us with information at once interesting and practical; it would be still easier to prove, as in the cases of Brown and Broussais, that vital physiology, by involving us in the discus- sion of subjects beyond the powers of our reason, never fails to en- tangle its votaries in a labyrinth, amidst whose mazes they move without progressing, and consume in idle speculations that time and labour they ought to spend in the acquisition of useful know- ledge. But I trust the period is at length arrived when this error will be avoided; for, on the whole, it must be confessed, that in consequence of a wrong method of studying, and a misconception of the true objects of physiology, this science has in many instances retarded the progress of practical medicine. Let us next consider the connection of morbid anatomy with practical medicine. Many have mistaken the end and object of morbid anatomy, and there are not wanting some who even deny its utility, while others again, in their zeal for its improvement, have endeavoured to extend its limits, so as to make it comprehend and embrace in the explanations it affords all the phenomena of disease. It is not easy to determine which of these parties has most injured the cause of practical medicine. Morbid anatomy comprehends not merely decided and permanent structural altera- tion, but embraces, so far as they are capable of being detected, 4 graves’s clinical lectures. even temporary physical changes in internal organs. In order justly to estimate its importance, we should recollect that the first alteration in the texture of a part is not the cause but the conse- quence of disease, for in every healthy organ the texture is natural, and as every change of texture is produced in consequence of de- rangement in the vital action of the vascular system of the part, it is obvious that structural alteration must, in the first instance, be always produced by functional derangement. Thus, the physical alterations which attend external inflammation—the tumefaction, the heat, the redness, are not the causes but the consequences of disease. But in thus reducing them to the rank of symptoms, do we diminish their importance ? Certainly not. For being imme- mediately connected, as effects, with the primary cause, they prove the most useful of all symptoms, in enabling us to ascertain the seat and progress of diseased action. In this respect they possess a manifest advantage over the general or constitutional symptoms. Thus, in cases of spontaneous gangrene, phlegmonous inflamma- tion, or erysipelas, what practitioner would be contented to draw his indications from the general symptoms, disregarding the appear- ance of the affected part? And yet this is exactly what those per- sons do, who refuse the aid of morbid anatomy in the treatment of internal disease. In external diseases most of the physical changes in the affected part can be at one recognised ; their diagnosis is therefore compara- tivelyeasy, and their treatment well established. In internal diseases the case is widely different, the physical alterations are here beyond the cognisance of our senses ; and, in order to ascertain their nature and situation, we must carefully compare the morbid appearances of internal organs, as revealed to us by dissection, with the symp- toms during life. Although alteration of structure is in the first instance produced by a disease in the vital action of the part, yet this structural alteration may itself become a new cause of mischief. Thus the vascular system of the lungs, from some unknown cause, assumes such a change of action as produces a deposition into the pulmonary texture of various fluid and solid products, by which the entrance of the air into its vesicles is prevented, and the respi- ratory function, one of the most important of the body, is thus con- siderably deranged. Again, whatever be the original vital derange- ment which causes scirrhus of the pylorus, the obstruction thus formed is a secondary cause of new and important symptoms. Another consideration, which enhances the value of morbid ana- tomy, arises from the fact, that when diseased action fixes itself in any part of the body, whether external or internal, and there gives rise to physical alterations, experience teaches us, that the progress of the disease may be often arrested by removing its effects. Thus, to recur to the example of external inflammation, the redness, the swelling, the heat of the part are but symptoms, and yet we find great benefit from the applications of remedies capable of diminish- ing them ; hence we leech, and apply cold lotions, &c. From all these considerations it is evident, that whenever disease is attended GENERAL OBSERVATIONS. 5 with either a temporary or a permanent alteration in the tissue of an internal organ, it will be of the greatest practical importance to ascertain the nature and extent of that alteration, and the progress of practical medicine will be exactly proportioned to the accuracy with which this can be accomplished. Thus, how much has the treatment of pectoral diseases been improved by the application of auscultation and percussion, means which are only useful by en- abling us to ascertain the physical alterations induced by the disease, or in other words, the morbid anatomy of the affected organ. Without their aid, how trace the progress and follow the increase or diminution of pulmonary inflammation ?—how demon- strate the existence of dropsical or pleuritic effusion within the chest?—how distinguish with certainty pleurodyne from pleurisy? I could prove the utter impossibility of distinguishing many cases of bronchitic from tubercular phthisis without their assistance. I might refer to chronic emphysema of the pulmonary tissue, a dis- ease of great importance, but actually unknown before the time of Laennec, who first accurately described it in the dead body; indeed, before the application of percussion and auscultation, a perfect knowledge of this derangement of the pulmonary structure in the dead body would not have assisted our diagnosis, for how recog- nise it during life? I might bring forward dilatation of the bron- chial tubes, another disease wholly unknown before Laennec’s time, and which, before his discovery, could not be recognised by the common method of observation. I might enlarge upon the great utility of attending- to the changes which take place within the chest in measles and scarlet fever, but the benefit resulting from an accurate acquaintance with the morbid anatomy of the thoracic cavity is now so generally acknowledged, that I shall rather choose my illustrations from other classes of diseases. Nosologists, until very lately, were agreed in attributing con- siderable frequency to those cases of apoplexy and paralysis which arise from serous effusion into the brain, or from a mere functional inaction or debility of the cerebral and nervous systems. This opinion was founded partly on speculative grounds, and partly on inadequate and imperfect post-mortem examinations, and in prac- tical books the symptoms supposed to announce sanguineous, serous, and nervous apoplexy, were dogmatically laid down. What was the consequence ?—Most disastrous, as I have had occasion to wit- ness, in some parts of the continent, where the elderly practitioners still adhered to the practice founded on this false pathology. What can be more melancholy than to see time wasted or misemployed in the exhibition of diuretics, to promote absorption of the serum effused into the brain, or of strong exciting remedies, such as arnica, camphor, &c., to overcome the nervous debility, in cases where copious depletion by the lancet and purgatives were urgently necessary. I do not deny that in some rare cases effusion into the brain is the cause of sudden death from apoplexy. I have seen such an event supervene in chronic dropsy, but there the termina- tion was very sudden, and the state of the case left no doubt as to G graves’s clinical lectures. the cause; but in the majority of the cases formerly treated as serous or nervous apoplexy a more careful examination would have detected marks of vascular excitement, or local inflammation, a subject I shall treat at large when on the pathology of the brain. A similar error in morbid anatomy led to a similarly erroneous practice in the treatment of hydrocephalus, and many cases of general and local dropsy. The effusion occupied the sole attention of pathologists ; the marks of preceding vascular excitement or inflammation escaped their notice. Time will not permit me to enlarge upon the light which morbid anatomy, rationally pursued, has shed upon diseases of the brain. It is sufficient to remark, that some of the most important modifica- tions of inflammation in that organ have been only lately discovered, and it is only lately that a minute and extensive examination of the different changes the brain undergoes in disease has begun to intro- duce a certain degree of regularity and precision into a department where all before was confusion and inaccuracy. Examples of the utility of morbid anatomy might be brought forward without num- ber :—the discovery of local inflammation being at times the cause of a disease in most of its symptoms resembling common ague ; the use of the lancet in the cold stage of ague, a practice which may be advantageously resorted to, in cases where each return of the fit is accompanied by a recurrence of inflammation in a vital organ, as the lungs or brain ; the connection between inflammation of the mucous membrane of the stomach, and some of those symptoms of fever formerly attributed to mere debility ; the influence of cerebral inflammation and congestion, in producing the symptoms formerly vaguely denominated typhus; the low character which fever as- sumes when accompanied by pneumonia (and that, too, often latent); the symptoms which are produced by follicular ulceration of the intestines, which so frequently occurs in the course of fever ; the diagnosis between the pain produced by neuralgia of the abdo- minal nerves, and that resulting from structural diseases of the intestinal canal; a more accurate knowledge of the state of the mucous membrane in the diarrhoea of phthisis, and in intestinal tympanitis; the numerous improvements in the treatment of dis- eases of the ear, which followed Itard’s investigations concerning the morbid anatomy of that organ ;—these and many other disco- veries, all replete with practical advantages, are the results of the attention of our cotemporaries to morbid anatomy; and, were I to appeal to the records of surgery, I might bring forward examples, if not more important, perhaps more evident and striking ; for the invention and success of most capital operations depend on a per- fect knowledge of the structural derangements, the removal or cure of which is attempted. Of this, examples suggest themselves on every side, but none is more striking than the one devised by Dupuytren for the cure of artificial anus, the most disgusting and loathsome malady to which human nature is subject, and deemed altogether incurable, until that excellent surgeon, by a combination of profound pathological and physiological knowledge, succeeded in GENERAL OBSERVATIONS. 7 planning and executing an operation, that were alone sufficient to immortalise his name. The study of morbid anatomy, however, is attended with no ordinary difficulties, and, when imperfectly understood, is liable to lead to erroneous results, for it requires much candour, much patience, and that experience which can be only acquired by long continued practice, to enable us to judge concerning diseased appearances. The power of accurately discriminating in the dead body the traces of disease cannot be suddenly acquired, and so numerous are the various errors to which superficial observers are liable, that much injury has thus resulted to medical science, dis- eased appearances being in some cases overlooked, and in others recorded where they did not exist. Those who are aware how often the congestion, which frequently takes place immediately before or after death, in the pulmonary tissue, in the mucous mem- brane of the lungs and alimentary canal, and who know how often this congestion alters the physical properties of these parts, so as almost exactly to simulate the vestiges of inflammation, will under- stand how it happens that in investigations connected with the real or supposed diseases of these parts, facts have been marshaled against facts, and observations arranged against observations, until the path which promised simplicity and order terminated in per- plexity and confusion. Hence the doctrines of Broussais received so many corroborations, and appeared to rest upon a numerous series of undoubted and well-authenticated facts. The morbid anatomist must of all things beware of seeing too much. He must avoid imposing on himself by every where seeing exactly what he expected to see, and above all things let him not always force himself to see something; for many diseases proceed to a fatal termination without having produced any evident morbid alteration. When I come to treat of the pathology of the brain and nervous system, I shall have occasion to advert to errors which late authors have committed from too great an anxiety on the one hand to reduce to a certain and definite system the morbid appearances of the brain and spinal marrow, as connected with their diseases, and, on the other, to find, in every case where the cerebral or nervous functions had been diseased, lesions of structure to account for the symptoms. Thus, to cite one of numerous instances, I shall have occasion to prove that epilepsy and mania often commence suddenly and vio- lently, without the existence of any organic alteration ; and, in- deed, that organic lesions are not necessarily connected with these formidable diseases is sufficiently proved by the occasional sudden manner in which they cease. Thus, a gentleman of great literary reputation was many years a patient of mine before his death, which happened in 1831, at the age of seventy. From the age of twenty-five to fifty-five he suffered from violent and frequently recurring fits of epilepsy; after having continued thirty years the disease ceased suddenly, without any assignable cause, and for the last fifteen years of his life he had not a single fit. I shall have 8 GRAVES’s CLINICAL LECTURES. occasion to show you how fine-drawn and how ill-founded the observations of those who profess to account for every nervous dis- turbance during1 life by cerebral lesions, who profess to distinguish accurately during life inflammation and irritation of the arachnoid or dura mater from irritation or inflammation of the brain itself, who maintain that one series of symptoms is produced by inflam- mation of the cortical, and another by inflammation of the medul- lary, substance, who have strained their eyes to discover, and their veracity to impose upon us. proofs that inflammatory or other dis- eased states of certain portions of the brain caused invariably similar affections of certain mental functions. These errors of some, even of the most eminent French pathologists, it will be my duty to notice from time to time; but I am sorry to say that much more unpardonable errors and misstatements have found their way into English and Irish publications on the pathology of the brain, and which I shall be compelled to speak of hereafter. Having made the preceding observations on the dangers which arise from an ill-directed application of the studies of physiology and morbid anatomy to the practice of medicine and surgery, I feel myself imperatively called on to present the other side of the ques- tion to your view, in exposing the still more dangerous doctrine advocated by those who depreciate the value of pathology and morbid anatomy as only instructive after the death of the patient, and even then as not unfrequently calculated rather to mislead than to advance the interests of practical medicine. It must be conceded, that he who is only a physiologist, cannot hope to cure disease, and that the mere morbid anatomist will be often misled by post-mortem appearances, if he has not attentively watched the progress of symptoms, and the effects of medicines, during life; for, unless this be done, he will, as I have already said, often mistake secondary for primary lesions, will confound effects with their causes, and will refer to certain alterations of structure, that which had originated in a functional disorder, a morbid state of parts very different from that which is observed after death. But when, to an accurate knowledge of physiology and morbid anatomy is joined an extensive observation of the progress of symp- toms, and the effects of therapeutical agents, how much more certain and satisfactory will be our practical decisions, and how much more likely our efforts to be attended with success, than if we merely studied disease at the bed-side of the patient. In the latter case, we might, indeed, become expert nosologists, be accu- rately acquainted with certain groups of symptoms, and even not unfrequently adopt the proper method of treatment. These symp- toms, considered together, we would call by a certain name, and hand down to posterity this new acquisition of medical knowledge, perhaps clothed in the garb of a dead language, and invested with the false dignity of a learned tongue. But what have we really thus effected for posterity? Our followers read our definitions of disease with an acquiescing admiration, and, sure of the efficacy of the remedies we have recommended, they go forth with an over- GENERAL OBSERVATIONS. 9 weening confidence in quest of the group of symptoms we have described, and when they have met with them, they look upon their task as already half accomplished, and promise a successful termination of the disease. “ Tell me the name of the disease,” was the motto of the nosologist, “ and I will tell you the remedy but, gentlemen, I will engage to tell you the names of a hundred diseases, without your being able to name the proper method of treatment. I tell you a man has dropsy, his limbs are anusarcous, water is accumulated in the peritoneal cavity, his urine is scanty, and his thirst increased. Will you, from this very excellent noso- logical definition, venture to prescribe for this case of dropsy ? For the sake of the suffering patient, and your own conscience, pre- scribe not on such data. And yet I regret to be obliged to say, that such a method of procedure is by no means rare, nay, it is even a matter of daily occurrence. But this case of dropsy will not yield. Some other boasted specific hydragogue or diuretic is had recourse to; still the patient grows worse and worse, and finally dies, but his friends are not discontented with the medical attendant, who excuses himself by asserting that he has succes- sively resorted to every remedy which has been recommended in dropsy; and, in truth, if you look over the list of medicines exhi- bited in rapid succession, you will probably find that his excuse is not unsupported by facts. But these cases in which every thing has been tried, are exactly those in which nothing has been tried, in which medicine has followed medicine, and each symptom of disease has indiscriminately been the object of attack, until death approaches with accelerated step, and charitably closes a scene dis- tressing to humanity, and disgraceful to the cause—I was going to say—of science; but who will venture to give so ennobling a name to this pseudo-practical knowledge—this worse than absolute igno- rance 1 Gentlemen, I am not combating phantoms; I do not, Quixote- like, contend with imaginary giants; no, what I have described, exists, the picture I have drawn has many an original. But let us have done with this subject; let us turn to the gratifying consider- ations of the progress which practical medicine is making under its parent science—physiology and morbid anatomy. The reason of man is now more fully employed than at any former period, a vast store of mental power, a vast mass of mind, is every where at work ; what formerly was vainly attempted by the labour of a few, is now easily accomplished by the exertions of the many. The empire of reason, extending from the old to the new world, from Europe to our Antipodes, has encircled the earth—the sun never sets upon her dominions—individuals must rest, but the collective intelligence of the species never sleeps; at the moment one nation, wearied by the toils of day, welcomes the shades of night, and lies down to seek repose, another rises to hail the light of morning, and, refreshed, speeds the noble work of science ! All enquiries commence, as it were, at the same point, as the labours of their predecessors are equally at the disposal of all, and, 10 graves’s clinical lectures. consequently, it is not surprising we should often find them arriv- ing together at the same end; thence the numbers of simultaneous discoveries of the same fact now so common. It is not unusual to find the publications of France, Germany, Italy, and England, simultaneously announcing the same discovery, and each zealously claiming for their respective countrymen an honour which belongs equally to all. I am sorry to say that, with some splendid excep- tions, this interesting and innocent controversy has been carried on by other countries, while Ireland has put in no claim for a share of the literary honours awarded to the efforts of industry or genius. But, gentlemen. I hope that this state of inaction, this state of mental torpor, has ceased, and that the time has passed away when we could not point out among our brethren any who had advanced the boundaries of the medical sciences, and thus promoted the inte- rests of humanity. Already have the names of several of the senior members of the profession been spread abroad ; already has the scientific character of this city been elevated by such men as Dease, Blake, Colles, Carmichael, Cusack, Crampton, Marsh, and Kirby; and already have some of the junior members of the profession attached their names to discoveries which shall be commemorated as long as anatomical sciences are cultivated ; I need scarcely add that I allude to the names of Jacob and of Houston. The interest- ing descriptions given by these gentlemen of their respective disco- veries, in a department of human anatomy in which all further dis- covery was looked upon as hopeless, are probably known to you all, and therefore it is unnecessary now to enlarge upon them. Neither have we, at present, leisure to enter into the no less inte- resting field of investigation which Dr. Corrigan has opened, by the publication of his experiments on the sounds and motions of the heart—experiments leading to conclusions so novel, that most physiologists were at first incredulous, and many even ventured boldly to call into question their accuracy. Without, at present, venturing to decide whether Dr. Corrigan’s opinions be in every respect correct, I may assert that his paper is written in the true spirit of philosophical enquiry, and that he deserves opponents of a far higher grade than those who have endeavoured to refute his arguments in the English periodicals. With regard to the treatment of disease, we must not omit the discovery, by Mr. Carmichael, jun., of this city, of the curative effects of spirits of turpentine in iritis ; for although we were in pos- session of two valuable remedies for the cure of this disease, bella- donna and mercury, yet there are cases in which it is useful to be able to accomplish a cure without the aid of salivation. It is with feelings of the greatest satisfaction and pride, that 1 claim the right of adding to this list the names of three gentlemen, whose friendship I have long enjoyed, Mr. Adams, Mr. M‘Dowell, and Dr. Stokes. Of the two former, it is unnecessary to speak, their contributions to science are so well and so duly appreciated. Concerning the latter, my colleague, Dr. William Stokes, I shall impose upon, myself an unwilling and constrained silence, partly CHRONIC BRONCHITIS. 11 because his merits claim a warmer and longer eulogy than would suit this time and place, but chiefly because his labours have placed him in a position, as, far elevated above the necessity of praise, as above the fear of censure. Neither shall I allow myself to eulogise, as they deserve, the talents and exertions in the cause of science rendered by Professors Apjohn, Harrison, Kane, Montgomery, and E. Kennedy. They all rank high among the successful cultivators of some of the most useful departments connected with our art; their names, associated with those already enumerated, form a cata- logue the subject of congratulation for the present, of happy augury for the future, for cold must be the breast of him who will not hail with joy every symptom of our country’s literary regeneration, dead the feelings which are not elated at the boon conferred on our species by every advance made by those who devote themselves to the grand, the noble pursuit of relieving the suffering, of healing the diseased ; but time bids me stop ; I shall, therefore, conclude by observing that the attention lately devoted to the distinctions be- tween real and pseudo morbid appearances, the diligent cultivation of morbid anatomy by men not the slaves of preconceived opinions, the abandonment of all systems whose baseless fabric rests on the phantoms of vital physiology, the importance now justly attached to medical statistics, to the study of endemic and epidemic mala- dies, to the operation of morbid poisons; these, and various other circumstances, give us reason to hope that the progress of the human mind, in investigating the means of preventing and curing diseases, will not be less rapid than it has been in the other depart- ments of knowledge; and thus it will be proved, that if man has passions which impel him to the destruction of man, if he be the only animal who, despising his natural weapons for attack or de- fence, has devised new means of destruction, he is also the only animal who has the desire, or the power, to relieve the sufferings of his fellow-creatures ; the only animal in whom the co-existence of reason and benevolence attests a moral as well as an intellectual superiority.

Allow me to direct your attention to day to the case of J. Jowson in the chronic ward, labouring under an attack of exasperated chronic bronchitis—a disease which derives its chief importance 12 graves’s clinical lectures. from the circumstance of being exceedingly common. There is no morbid affection of the system more frequent or more general than chronic bronchitis; it is of every-day occurrence in dispen- sary practice; it is one of those cases which you will be constantly called on to treat; and hence the study of its nature and treatment has strong claims on your attention. This man is, as you have seen, about the middle age in point of years, but he is old in constitution. In this country you will find most of the labouring poor exhibiting symptoms of premature old age—the combined result of poverty, intemperance, and hardship. Obliged to work in the open air in bad weather, they get catarrhal affections, which are renewed by repeated exposure, and prolonged for want of proper care. The natural effect of cold frequently renewed and generally neglected is, that a tendency is produced in the bronchial mucous membrane to become congested and inflamed with facility, until at length the derangement becomes permanent, and the mucous membrane no longer returns to its normal and healthy condition during the intervals. The secretion of the mucous membrane of the bronchial tubes, in a perfectly healthy person, is almost entirely destitute of matter to be expectorated. In the normal state, the secretion of the bron- chial mucous membrane, though continually going on, scarcely ever exists in superfluous quantity, for a certain proportion of it is carried off by exhalation or absorption; a'perfectly healthy person, breathing a pure air, has no expectoration whatsoever. The moisture secreted by his bronchial mucous membrane contains nothing that the expired air cannot carry away in vapour, without leaving any residuum which, gradually accumulating, would at length require to be expectorated. In this respect the bronchial mucus in the healthy state differs from the mucus of other mem- branes of the same class; but disease destroys this beautiful pro- vision, and gives rise to a secretion of morbid mucus which cannot be gotten rid of in the usual way, and which must therefore be expectorated. Hence it is that persons, in whom a chronic state of congestion of the bronchial membrane has been generated by re- peated colds, have a secretion of superfluous matter always going on, and are constantly expectorating. This may continue for seve- ral years without much inconvenience; the principal annoyance the patient suffers is in getting up the phlegm in the morning. At this period there is always an accumulation of fluid in the lungs after the night, during which the cough is less frequent, and expec- toration less copious. Here let me remark, that, although a person may cough violently during his sleep, he never expectorates. Expectoration is accom- plished by the attention being directed to the chest, by an act of volition being put in force, so as to cause a constriction of the bronchial tubes, and generate a current of air of sufficient strength to expel the mucus. To effect this, the mere act of coughing is not sufficient, and consequently we do not expectorate during sleep ; for this purpose it is necessary for the patient to be awake. CHRONIC BRONCHITIS. 13 Frequently recurring catarrhal affections, besides generating a state of chronic derangement of the mucous lining of the lungs, have a necessary tendency to produce other bad effects. Dyspnoea is an ordinary attendant on chronic bronchitis ; the vesicular tissue, enfeebled by disease, loses its natural elasticity; and hence the act of respiration is performed weakly, and with considerable diffi- culty. In addition to this, the stress thrown on the air cells and passages gives rise to emphysema and dilatation of the bronchial tubes. When this man came into the hospital, he was labouring under an exacerbation of his chronic bronchitis, from a fresh attack of cold; he also suffered from dyspncea with a tendency to emphy- sema, and had been much debilitated by the frequent recurrence of his pulmonary symptoms. I do not intend to make any particular observations here on acute bronchitis supervening on chronic ; it is a dangerous disease, requiring prompt and careful attention. I merely refer to this case to point out the remedies which were em- ployed, and the principles which guided me in their selection. At the time of our patient’s admission, the fever which accom- panied the acute attack had subsided. His pulse was tolerably quiet, neither did he present any derangement of the heart’s action, and, so far, had escaped one of the consequences of chronic disease of the lung—namely, dilatation and hypertrophy of the right ven- tricle. Observe, the most important features in this case, so far as treatment is concerned, were these: there was no general inflam- matory condition of the system present; he had neither hot skin nor quick pulse; his expectoration was copious; the chest sounded well on percussion, and the only stethoscopic phenomena observed were extensive minute and moist bronchial rales. The case then stood thus : extensive bronchial inflammation with copious expec- toration, unaccompanied by fever, and occurring in a debilitated constitution. All weakening measures were therefore contra-indi- cated. It is true that the man had dyspncea, and complained of tightness across his chest—circumstances which might appear to demand the use of the lancet or leeches; if these means had been employed, he would certainly have experienced some relief; but in the course of a few hours the symptoms of distress would have returned, the weakness superinduced by bleeding would give rise to increased secretion into the bronchial tubes, and the patient would be worse than before. Under these circumstances, we re- frained from using the lancet or leeches ; but, deeming it advisable to get rid of the last traces of inflammatory action, we gave the following mixture:— R. Misturae amygdalarum, gxij., Nitratis potassse, 3 ij-, . Tartar, emetici, gr. j., Tinctur. opii camphorat., 3 ss. Ft. mistura pectoralis, sumat cochleare j., amplum omni hor&, vel urgente tusse. 14 GRAVES’S CLINICAL LECTURES. In explaining the rationale of this mixture, it is hardly necessary for me to state why the almond emulsion was used. In all cough bottles it is of importance that the basis should consist of some mild mucilaginous fluid; and hence we generally employ for this pur- pose demulcent syrups, emulsions made with olive oil, spermaceti, or almonds, or decoctions of mucilaginous seeds and roots. With the almond emulsion we combined tartar emetic and nitrate of potash—both antiphlogistic remedies, and calculated to act with peculiar effect in relieving congestion of the bronchial mucous membrane. You are aware that nitrate of potash in large doses is a powerful antiphlogistic, and you have seen it prescribed with excellent effects in cases of acute arthritis treated in this hospital. Nitrate of potash, when given to the amount of two or three drams in the day, combined with two or three grains of tartar emetic, is, next to bleeding, the most efficient means we possess of reducing inflammatory action; and were I to be asked what remedies I should employ in combating inflammation—supposing there were no such things as the lancet, or leeches, or calomel—I should certainly say nitrate of potash and tartar emetic. When given in small doses, this combination proves also extremely serviceable in less severe cases, and it was on this account we gave it in the present instance. To this we joined the camphorated tincture of opium, convinced that its stimulant properties could not prove injurious when com- bined with antiphlogistics, although it would be improper to admi- nister it alone. Experience has taught that when camphorated tincture of opium is given, in cases of chronic cough with expec- toration, it will (if much inflammatory action be present) check the expectoration and bring on dyspnoea. But when combined with nitrate of potash and tartar emetic, its bad effects are corrected, while its sedative influence remains unimpaired. In addition to this, I ordered the nitro-muriatic acid liniment to be rubbed over his chest. This liniment we are much in the habit of prescribing where a rubefacient is required. It is made by dili- gently mixing one dram of nitro-rpuriatic acid and one ounce of lard, by means of a wooden or ivory spatula. When this mixture is complete, two drams of spirits of turpentine are added; these ingredients soon separate from, and mutually react upon each other, so that the liniment is spoiled; we, therefore, never make it in large quantities. As his bowels were constipated, I gave him a pill composed of three grains of blue pill, quarter of a grain of col- chicum, two grains of scainmony, and half a grain of capsicum. Colchicum acts on the biliary secretion, particularly when combined with blue pill, and hence promotes the general action of the intes- tines. With these I combined a little capsicum, in consequence of the patient’s complaining of being annoyed by constant flatulence. It is a curious fact, that every chronic derangement of the bronchial mucous membrane is accompanied by flatulence. Whether this arises from the irritation of the bronchial membrane spreading by continuity of tissue, and rendering the tongue foul, the stomach weak, and the digestive function unnatural: or whether the de- CHRONIC BRONCHITIS. 15 rangement. of the bronchial mucous membrane, and the imperfect performance of the function of respiration, cause the secretion of air from the lungs to be diminished, in consequence of which air is secreted from the intestinal mucous membrane by a vicarious action—I cannot exactly state, but I think the latter hypothesis not very improbable. It is well known that the mucous membrane of the stomach and bowels enjoys the power of secreting and absorb- ing air; it secretes carbonic acid, nitrogen, and also other gases which seem peculiar to it—such as sulphuretted hydrogen. I am not aware that there is any distinct evidence that the last-named gas is ever secreted by the bronchial mucous membrane, but, as there are some cases in which the breath is remarkably fetid, I think it remains for future experiments to decide whether it may not be so under certain circumstances. It is, however, by no means improbable, that when an adequate cause produces considerable derangement in the respiratory function, and alters the nature of the aerial secretion from the lung, the mucous lining of the stomach and bowels may take on a vicarious action, and secrete gases ana- logous to those which in the normal state are secreted by the mucous membrane of the bronchial tubes. I think I have seen some well marked examples of this translation of the function of secreting air from the pulmonary to the intestinal mucous system in cases of spasmodic asthma and hysteria. I have seen patients who, pre- viously to an attack of asthma, had no symptoms of flatulence, and observed that, accordingly as the disease proceeded and the derange- ment of the respiratory function increased, the bowels became dis- tended with air. In hysteria, also, where derangement of the respiratory function is plainly denoted by the heaving of the chest, sighing, and dyspnoea, there is generally enormous and sudden inflation of the belly, loud borbyrygmi are heard, and there is a constant disengagement of air upwards and downwards. But to return to our patient. After we had removed all traces of active inflammation, and the case had been reduced to one of ordi- nary chronic bronchitis, we changed his cough mixture for the fol- lowing :— R. Misturse ammoniaci, 3 vj. Carbonatis sodae, 3 ss. Tincturae opii camphorat, 3 ss. hyoscyami, 3j. Vini ipecacuanhae, 3 ij- Fiat mistura pectoralis, sumat. cochl. j. amp. pro dose. The carbonate of soda was given with the view of removing some' acidity of stomach which he complained of; besides, it is a fact that alkalies produce good effects in many cases ef pulmonary irri- tation, as must have struck you from witnessing the success of the popular remedy for hooping-cough, recommended by Mr. Pearson. You will observe, gentlemen, how very different this cough mixture is from the former, it is much more stimulating, and, at the same time, more powerfully anodyne, the opium being here less diluted, 16 graves’s clinical lectures. and being aided by henbane ; the addition of ipecacuanha was in- tended to prevent a too speedy action on the part of the other ingre- dients, in diminishing the expectoration and constipating the bowels. I wish to call your attention to the plan of treatment, not with reference to this case alone, but with respect to chronic bronchitis in general. We first gave a combination of nitrate of potash and tartar emetic, with the view of removing any remaining traces of inflammatory action ; we next prescribed the misturse ammoniaci, with camphorated tincture of opium and carbonate of soda, &c.; and, finally, when the cough became entirely chronic, we gave the compound iron mixture, with tincture of hyoscyamus, in draughts, and an electuary, consisting of sulphur, cream of tartar, and senna. I need not repeat what you will find in every treatise on materia medica, with respect to the use of the compound iron mixture ; it is not to be given until all traces of fever and local inflammation are removed, and never until the secretion from the lungs is copious, and expectoration free. In such cases, the patient is generally weak, and the inordinate secretion adds to his debility. Here the compound iron mixture proves extremely serviceable, but you should com- mence its use with caution. Some persons are in the habit of giving it in doses of half an ounce, two or three times a day; this I never do; I begin with a dram, twice or three times a day, in an ounce of spearmint water, and add from half a dram to a dram of tincture of hyoscyamus. The dilution with mint water, and the addition of tincture of hyoscyamus, render it more valuable, by causing it to be more easily borne by the system, and less likely to be rejected by the stomach. Let me now explain my reasons for ordering the following electuary:— R. Electuarii sennae, 3 iij. Pulveris supertart, potassse, 3 j- Sulphuris loti, 3 ss. Syrupi zingiberis, q. s. Ut fiat electuarium, sumat cochleare, j. parvum bis vel ter quotidie. In the first place, when giving any stimulant medicine internally, it is essentially necessary to attend to the state of the bowels; in the next place, keeping the bowels freely opened, has a very re- markable effect in diminishing inordinate secretion from the bron- chial tubes. Where the patient’s strength can bear it, I often diminish supersecretion from the lung by strong hydragogue pur- gatives, as you saw in the case of a patient in the chronic ward, who had orthopnoea, and such an excessive secretion into the bron- chial tubes as to threaten suffocation. The patient being a strong man, and having no symptom of intestinal irritation, I prescribed a bolus, composed of a grain of elaterium, two of calomel, ten of jalap, and five of scammony, forming a powerful hydragogue pur- gative, which produced several fluid discharges. The man bore its operation well, and 1 repeated it in two days with the most decided benefit; indeed, he experienced from it more complete CHRONIC BRONCHITIS. 17 relief than he would have done from bleeding', blistering, or any other remedial means. In some cases of bronchitis with excessive secretion, you will be able to produce very striking effects by the use of hydragogue purgatives; this, however, will require both judgment and discretion, and it should be borne in mind, that, in the majority of cases, there are many circumstances which contra- indicate their employment. With respect to the use of sulphur in this case, I was led to pre- scribe it, in this and many other similar cases, from observing that chronic cough, and long-continued congestion of the bronchial mucous membrane, were more effectually relieved by the use of sulphureous waters, such as the Lucan and Harrowgate Spas, than by any other remedy that could be devised. I may here also observe, that the Lucan waters produce very striking effects in dis- eases of the skin, and that I have seen intractable cases of psoriasis, which lasted for years, yield to the use of the Lucan waters. It would appear that sulphur, when taken into the system, is either eliminated by the kidneys in the form of sulphates, or exhaled from the skin and mucous tissues in the form of sulphuretted hydrogen, and in this way we arrive at some explanation of its action in diseases of the skin, and chronic irritation of the bronchial mucous membrane. In fact, paradoxical as it may appear, sul- phur, although evidently stimulating, is nevertheless very effica- cious in curing many diseases connected with, or depending on, inflammation or congestion. Thus exhibited internally and pro- perly combined, what remedy gives such prompt and certain relief in that painful affection, piles? How rapidly does the specific irri- tation of the skin, termed scabies, yield to its use ! These, and similar facts, which might be brought forward in abundance, ought to countenance the use of this medicine in certain chronic inflam- matory affections of the bronchial tubes. The celebrated Hoffman was in the habit of adding sulphur to his cough prescriptions in all cases of chronic bronchitis in the aged and debilitated; and I have no doubt that from five to ten grains of sulphur, taken three or four times in the day, is one of the best remedies that can be prescribed in cases of chronic cough, accompanied by constitutional debility and copious secretion into the bronchial tubes. Within the last four years, my attention has been particularly directed to the use of sulphur in this and other affections, and I can state from expe- rience that it is a most valuable remedy. As it has a tendency to produce elevation of the pulse, increased heat of skin, and sweating, it will be necessaay to temper its stimulant properties by combin- ing it with cream of tartar, which is a cooling aperient,- and has the additional advantages of determining gently to the kidneys.1 The addition of the electuary of senna gives additional value to the com- bination, and quickens its action on the intestines. Such, gentlemen, are the principles that guided me in prescribing for this man. The long continuance of the complaint, the serious 'Baglivi has well said, “In morbis pectoris ad vias urinee ducendum est.” 18 graves’s clinical lectures. and extensive derangement of the pulmonary mucous membrane, the age, debility, and impoverished circumstances of the patient, forbid me to hope for a perfect cure; but he has been much relieved, and the same remedies applied to less desperate cases would have produced very striking effects. Still, if fortune were this moment to prove favourable to the poor fellow, if, when he leaves the hos- pital. instead of returning to hardship and exposure, he had the means of living in comfort, taking proper care of himself, traveling for health and amusement, and using a course of chalybeate spa waters, I have little doubt that with these aids the reparative powers of nature would succeed in obliterating every trace of pulmonary derangement. Permit me, gentlemen, to make a few observations here on what is popularly termed, cough. What is cough ? A sudden and violent expulsion of air from the lungs, produced by forcible con- traction of the diaphragm, aided by the abdominal and other expi- ratory muscles. What is the cause of cough? Pulmonary irrita- tion. What is the nature of this pulmonary irritation ? Here, gentlemen, is a question which every practitioner should put to himself when called on to treat a case of cough, and what affection is there which so frequently demands our assistance, and tasks our ingenuity? How abundant, how varied, are the examples of cough we meet with in our daily practice ! How obscure do we not find its nature on many occasions, and how difficult and per- plexing its treatment! Where the source of irritation is manifest, where the nature of the disease is simple and easily detected, where, after a proper examination, we can point to some part of the respir- atory system, and say here is the seat of the disease; in such cases, indeed, our course is sufficiently clear ; we may proceed with con- fidence, and practise with success. But how often are we, after weeks and even months of close and painful attention, baffled in our best-directed efforts, and forced to admit the humbling convic- tion that all our remedies are inefficient and useless, and that our character, as well as that of the profession, is likely to suffer in public estimation ! How often, too, do we discover with surprise, that the cough which we have been treating for weeks as a pure pulmonary affection, depends not on any primary derangement of the respiratory system itself, but upon the irritation of some distant organ, or upon peculiar conditions of the whole economy ! Before I proceed to enquire into the nature of the various sources of pulmonary irritation producing cough, I wish to remark that the exciting cause, or, in other words, that which immediately precedes and seems to give rise to a tendency to cough, is a sensation of tickling in the mucous membrane of the trachea, close to its bifurcation, and opposite the hollow at the fore part of the neck. It is also a curious fact that this sensation of tickling or itching is peculiar to this situa- tion, being never felt in any other part of the pulmonary mucous sys- tem. Whether the disease be seated above, as in case of laryngeal affections, orwhether it be below, as in case of disease of the lining membrane or parenchyma of the lung, it is here alone that the tickling CHRONIC BRONCHITIS. 19 sensation is felt. Another circumstance equally remarkable, and equally difficult of explanation, is the effect of position in cough. Persons labouring under slight bronchitis, or rather slight inflam- mation of the trachea, who scarcely cough half a dozen times in the course of the day, will, the moment they lie down at night, be seized with a violent and harassing cough, which may last for several minutes, and sometimes for hours, with little intermission. We can easily understand why empyema or pneumonia of one side of the chest may produce cough in certain positions and not in others, for here we have an obvious physical cause ; the accumulated fluid in the pleural cavity in the one case, and the diseased lung, whose specific gravity has been much increased by solidification, in the other, exercise an inconvenient degree of pressure on the sound lung, and hence give rise to irritation and cough, particularly in those positions which favour the operation of these physical causes of irritation. Here, however, the cause of irritation is very obscure. It may (but this I merely offer as an hypothesis) depend on the fluid secreted by the mucous membrane trickling over that part of the trachea where the tickling sensation is felt, the flow of mucus to this part being favoured by the recumbent position. That it does not depend on any supposed temporary congestion and irrita- tion of the lung, from the impression made on the skin by cold bed-clothes, I am quite convinced, for I have repeatedly observed it in persons warmly dressed, from merely lying down on a sofa close to the fire. You will, therefore, bear in mind, gentlemen, that although usually, when coughing is induced by any sudden change of position, we may infer that it is connected with some serious lesion of the lungs or pleura, yet we must not attach too much importance to this symptom in arriving at this conclusion, for cases are occasionally met with, in which mere tracheal or bronchial inflammation is attended with the same symptom to a very remarkable degree. I may observe, en passant, that the sensation of tickling or itch- ing appears to be almost exclusively confined to the skin. Here it appears to be dependent on slight causes, apparently incapable of producing that modification of nervous sensation termed pain. In other cases it seems to be connected with the rise and decline of the phenomena which indicate inflammatory action, arising in the first case (where it is generally less observable) from that nervous modification which precedes inflammation, and in the second being connected with some change in the nerves of the part which pre- cedes its return to a healthy condition. It does not appear to affect the mucous tissues, except in a very slight degree, and under pecu- liar circumstances. It is not observed in the pulmonary mucous tissue, except at that part of the trachea which I have already men- tioned, and it does not occur in any part of the intestinal mucous membrane. The only parts connected with the intestinal tube, in which it is felt, are the nose and on the anus, and here it is within the reach of scratching, the ordinary mode of relief. This is a for- tunate circumstance, gentlemen, for if any part of your bowels 20 graves’s clinical lectures. were to itch as your skin sometimes does the annoyance would be quite intolerable. If the presence of lumbrici in the small intes- tines, instead of producing a troublesome itching of the nose, as it often does,—if it produced, I say, a degree of itching equally intense in the mucous membrane of the bowels and stomach, what patient could endure greater torments than a person so afflicted? If ascarides gave rise to as intense a degree of itching within the colon, as they occasion at the verge of the anus, how dreadful would be the suffering thus induced ! Passing over the obvious and well known sources of pulmonary irritation, producing cough, such as bronchitis, pneumonia, &c., the first cause to which I shall direct your attention is one of not unfrequent occurrence, and where a mistake in diagnosis may lead to a practice useless to the patient and discreditable to the prac- titioner. The best mode of illustrating this is by giving a brief detail of a case which I attended with Dr. Shekleton. A young lady, residing in the neighbourhood of Dorset street, was attacked with symptoms of violent and alarming bronchitis. The fits of coughing went on for hours with extraordinary intensity ; it was dry, extremely loud, hollow, and repeated every five or six seconds, night and day, when she was asleep as well as when she was awake. Its violence was such that it threatened, to use a vulgar but expressive phrase, to tear her chest in pieces, and all her friends wondered how her frame could withstand so constant and so terri- ble an agitation ; and yet she fell not away proportionally in flesh, had no fever, and her chest exhibited nothing beyond the rales usually attendant on dry bronchitis. She was bled, leeched, blis- tered, and got the tartar-emetic mixture, but without experiencing the least relief. We next tried antispasmodics, varying and com- bining them in every way our ingenuity could suggest, still no change. We next had recourse to every species of narcotics, ex- hibiting in turn the various preparations of conium, hyoscyamus, opium, and prussic acid, but without the slightest benefit. Foiled in all our attempts we gave up the case in despair and discontinued our visits. Meeting Dr. Shekleton some time afterwards I enquired anxiously after our patient, and was surprised to hear that she was quite recovered and in the enjoyment of excellent health. She had been cured all at once by an old woman. This veteran prac- titioner, a servant in the family, suggested the exhibition of a large dose of spirits of turpentine, with castor oil, for the purpose of re- lieving a sudden attack of colic; two or three hours afterwards the young lady passed a large mass of tape worm, and from that mo- ment every symptom of pulmonary irritation disappeared. The next kind of cough, in which the cause of pulmonary irrita- tion is often misunderstood, is that which occurs in hysteric females. This kind of cough is one of the most alarming diseases in appear- ance you can possibly witness; in some it is loud, ringing, inces- sant, and so intensely violent, that one wonders how the air-cells, or blood-vessels, escape being ruptured. In others it is quite as incessant, occurring every two or three seconds, night and day, CHRONIC BRONCHITIS. 21 but is not very loud, and, indeed, in some it scarcely amounts to more than a constant teazing hem; in general the pulse is quick, but it is the quick pulse of hysteria, not of inflammation or fever. The patient suffers no aggravation of the cough from inspiring deeply, and her countenance exhibits no proof of malaeration of the blood, on the contrary it is blanched and pallid. She com- plains of variable or deficient appetite, headache, cold feet, and irregular or absent catamenia, although the cough continues for weeks, or even months, she does not emaciate like a person in incipient phthisis, although so much disturbed by the cough, and subsisting on so small a quantity of food. Here the history of the case, a knowledge of the patient’s habit, and the use of the stethoscope, are of great value. You will find that the patient is subject to hysteria, that she is generally pale and of a nervous habit, that the attack came on suddenly, and was superinduced by mental emotion, or some cause acting on the nervous system, or else arose gradually as one of the sequelae of catamenial disturbance, that the heat of skin and state of pulse are by no means proportioned to the violence of the symptoms, and the stethoscope will tell you that the signs of organic derangement of the lung are absent, you will thus be enabled to arrive at an accurate notion of the nature of the disease, and you will save the patient from the useless and often dangerous employment of anti- phlogistic means. Bleeding and leeching are, generally speaking, injurious ; such cases are best treated by stimulants, antispasmodics, and stimulant purgatives, together with the change of air, traveling, and the use of chalybeate spa waters. The third species of obscure cough, to which I shall direct your attention is one of deep importance for many reasons. It is that species of cough which depends upon pulmonary irritation con- nected with a venereal taint in the system. That syphilis may attack the pulmonary as well as the cutaneous, osseous, mucous, and other tissues, is not a discovery of modern times; it is a form of the disease long known, and you will find it mentioned by many of the old writers. Since syphilis has been classed by Willan and others among diseases of the skin, this notion seems to have been either abandoned or forgotten, but, as it strikes me, with very little justice. I entertain a firm conviction, that syphilis may affect the pulmonary as well as it does the cutaneous, or mucous, or osseous tissues, and that a patient, labouring under a venereal taint, may have irritation from this cause set up in the lung as well as in any of those organs in which it is usually manifested. The first per- son who mentioned this circumstance to me was the late Mr. Hewson, and since that time I have had repeated opportunities of confirming the truth of his opinion. Richter, Alibert, and Paget have well observed, that. Willan and Bateman’s classification of diseases of the skin is liable to the paramount objection, that it has no reference to the constitutional origin of cutaneous affections. I have the very same fault to find with modern treatises on diseases of the lungs. Pathologists have indeed enquired most accurately 22 GRAVES’S CLINICAL LECTURES. into the numerous morbid changes to which the pulmonary tissue is subject, but they have omitted a no less important part of their task, which is to investigate the states of constitution which origi- nated these changes. The agency, indeed, of scrofula has been enquired into with care, but how little attention has been paid to rheumatism, gout, syphilis, and scurvy, the fruitful sources of nu- merous diseases of the chest. By far the most interesting point connected with this affection is its diagnosis ; on this every thing depends. The great import- ance attached to the diagnosis arises from the circumstance of this disease presenting symptoms analogous to, and consequently being frequently confounded with, phthisis. A patient comes to consult you for cough ; you find him pale, emaciated, and feeble ; he sleeps badly, and is feverish at night, and has a tendency to sweat. Here there may be a double source of error. If the disease be mistaken for tubercle, and mercury not given, bad consequences will result; on the other hand, if tubercles be present, the effect of administer- ing mercury will be to precipitate the disease to a fatal issue. What is the nature of this disease, and how are you to recognise it? Mainly, I answer, by the history of the disease. If the pa- tient’s sufferings have commenced at the period of time, after primary sores on the genitals, when secondary symptoms usually make their appearance ; if some of his complaints are clearly trace- able to this source ; if, along with debility, night-sweats, emaciation, nervous irritability, and broken rest at night, we find cough; and if this group of symptoms have associated themselves with others, evidently syphilitic—such as periostitis, sore throat, and eruption on the skin—then we may, with confidence, refer all to the same origin, and may look upon the patient as labouring under a syphi- litic cachexy, affecting the lungs as well as other parts. In forming this diagnosis much caution and care are necessary, and we must not draw our conclusion until we have repeatedly examined the chest by means of auscultation and percussion ; if these fail to detect any tangible signs of tubercles, we may then proceed to act upon our decision with greater confidence, and may advise a suffi- cient but cautious use of mercury. Under such circumstances, it is most pleasing to observe the speedy improvement in the patient’s looks and symptoms ; the fever, night-sweats, and watchfulness diminish; he begins to get flesh and strength, and, with the symp- toms of lues, the cough and pectoral affection disappear. I am not prepared to say which of the pulmonary tissues is most usually attacked by the venereal poison, but I believe that it chiefly tends to the bronchial mucous membrane, although, like other animal poisons—e. g., those of measles and scarlatina—it may also occa- sionally produce pneumonia. The fourth species of obscure pulmonary irritation, producing cough, is that which is connected with a gouty diathesis. Gout may attack almost every tissue in the body. We may have it in the joints, as you are all well aware of; we may have it in the muscles and muscular aponeuroses, forming what has been termed CHRONIC BRONCHITIS. 23 the rheumatic gout; it occurs frequently in the fibrous tissues, and I have several times observed it in the cellular substance of various parts of the body, forming either diffuse oedema or tumours, which are exceedingly tender to the touch, and which are removed by treatment calculated to relieve the constitutional affection. It may attack the heart, giving rise to true pericarditis, or else to a func- tional disease with palpitations—a sensation of fluttering and sink- ing about that organ, and very remarkable intermission of the pulse; or it may affect the stomach, occasioning dangerous spasm or various dyspeptic symptoms; or it may seize on the intestines, producing irritation, colic, and gouty diarrhoea. I remember a pa- tient, of a confirmed gouty habit, expressing a great deal of sur- prise at getting an attack of gout in the testicle, for he could not conceive how a disease which generally affects the joints could occur in an organ so different in its nature. I replied, that the matter could easily be explained; because fibrous tissue, which gout most frequently attacks, enters into the composition of the testicle as well as that of the joints. Indeed, the testicle, with refer- ence to the texture of its envelopes and the extent of motion it enjoys, may be said to be provided with a sac-like joint. In like manner, gout very frequently attacks the mucous membrane of the trachea or bronchial tubes, causing a dry, annoying, and often a very obstinate cough. Where this cough comes on along with the fit of inflammation of the joints, its true nature is frequently overlooked, and it is believed to have originated in cold and to be mere common bronchitis. No matter what be the cause of inflammation in a gouty habit—no matter what the organ attacked by the inflammation be—it almost invariably assumes the character of true gouty inflammation. If a gouty person sprains a toe or an ankle, matters, after progressing for a time in the ordinary way, are sure in the end to exhibit a change of character; and the inflamed parts are observed either to grow unexpectedly worse, or to become stationary, at a time when a speedy termination of the local affec- tion seemed approaching. This is owing to its being now modified by the constitutional tendency to gout, which localises itself in the affected part. Precisely the same relations may be often observed between common bronchitis, produced by cold in a gouty habit, and the gouty bronchitis it indirectly produces. Gouty bronchitis often becomes chronic, continuing until it is relieved by a regular fit of the gout in the extremities. The fifth species of pulmonary irritation, in which the source of the disease is more or less obscure, is that which is connected with the scorbutic diathesis. It is important to be aware of this, par- ticularly for those who have charge of the health of the poorer classes, which is almost of more value than that of the rich, for on it their labour and their means of support depend. Among the poor, particularly in cities where the majority live on salt pro- visions, the scorbutic diathesis is very prevalent. It manifests itself either in the form of purpura, or in tendencies to hemorrhage from the nose, stomach, bowels, and bladder. It sometimes attacks the 24 graves’s clinical lectures. lungs, producing irritation of the bronchial mucous membrane, with cough and spitting of blood, and occasionally gives rise to pulmo- nary apoplexy. It is evident that pulmonic cases of this nature, originating in a scorbutic diathesis produced by confined air, damp lodging, and a salt diet, will require a treatment peculiar to them- selves, both during the attack and during convalescence. The last source of pulmonary irritation, to which I shall direct your attention, is that which proceeds from scrofula. You all know that scrofula has a tendency to attack every tissue in the body, but you may not perhaps be aware that it may affect those tissues in very different ways, and that scrofulous irritation may manifest itself in various forms, from the most trifling and transitory to the most extensive and permanent. I recollect a case I attended with Dr. Jacob, in which this fact struck me very forcibly. A fine boy, of high complexion, precocious intellect, and other marks of the scrofulous diathesis, got an attack of scrofulous ophthalmia of an intense character, and it required all the skill and ingenuity of Dr. Jacob to save him from blindness. During the period of our attend- ance, his brother (who was also of a strumous habit) began to com- plain of parts of his arm being sometimes a little sore. This circumstance attracted my attention, and on examination I found that several circular diffused swellings, of various sizes, often equaling half a crown in diameter, had successively appeared on different parts of his extremities and body. They evidently de- pended on inflammation of the sub-cutaneous cellular tissue, and exhibited a remarkable example of a most transitory local affection, produced by a constitutional cause—for these swellings arose, ar- rived at their acme, and subsided in the space of ten or twelve hours; they constituted, in truth, the first efforts of the scrofulous diathesis to localise itself, and, after a few weeks’ continuance, they were replaced by distinct and fixed, scrofulous inflammation of the metatarsal bones. Here was a very curious and instructive fact. A boy, evidently of a scrofulous diathesis, has circumscribed tumours, which arise, come to maturity of irritation, and subside in the course of a few hours. In some weeks afterwards, scrofulous irritation, in a decided and permanent form, fixes itself in the foot, producing inflamma- tion and ulceration. From this it may be inferred, that scrofula (for in this case I am firmly convinced these tumours were con- nected with strumous diathesis) may attack parts not only in its more permanent and destructive forms, but also in a manner so trifling and so transitory as to subside in a few hours, and leave no trace of its existence. The inferences deducible from this fact are numerous and important; for if scrofula may thus produce an acute and transitory inflammation of the sub-cutaneous cellular tissue, surely it may occasionally give rise to somewhat similar affections of internal organs—as the bowels, the lungs, &c.—and thus may occasion an acute bronchitis, a pneumonia, or an inflam- mation of the mucous membrane of the intestines, totally indepen- dent of the operation of cold, or the usual causes of such affections. SLEEPLESSNESS. 25 It has been too much the custom to refer merely chronic and fixed local inflammations to the agency of constitutional causes. The example before us proves that even the most transitory may have this origin. Scrofulous irritation may affect either the lining membrane or the parenchyma of the lung—giving rise in the one case to scrofu- lous bronchitis, in the other to scrofulous pneumonia; two affec- tions which may exist separately or combined, and either of which may prove fatal, with or without the development of tubercles in the lungs. Tubercles have, as I have elsewhere proved, too exclu- sively engrossed the attention of those who have investigated the pathology of phthisis; they are a very frequent product of the scrofulous diathesis, but the scrofulous bronchitis and scrofulous pneumonia are still more frequent and more important, and do not, as is falsely supposed, depend upon the presence of tubercles in the lungs. The pneumonia, the bronchitis, and the tubercles, where they occur together, are all produced by one common cause—scro- fula. Of this more hereafter. LECTURE III.

Two cases which have been recently under treatment in this hospital demand your particular attention,—the man who has been labouring under a severe attack of jaundice, and the boy who is recovering from fever. A remarkable symptom in both of these patients, and which must have repeatedly attracted your notice, was a total privation of sleep. In the former case the sleeplessness continued for a week, in the latter for nine or ten nights. Sleeplessness is a very curious result of disease. It accompa- nies certain morbid conditions of the system brought on by actual disease, or by grief, care, and various other forms of mental disturb- ance, continues to harass the unhappy sufferer night after night, and frequently resists the most powerful and decided narcotics. I do not intend to enter into any enquiry respecting the different states of the constitution in which it occurs; my purpose is merely to offer a few practical remarks on the more obvious and striking examples, with the view of illustrating the cases to which I have directed your attention. There is a form of sleeplessness which is frequently the pre- cursor of insanity, and which has been well described by my friend 26 graves’s clinical lectures. Dr. Adair Crawford. The watchfulness in such cases is accom- panied by the well known symptoms of incipient mental derange- ment, and its treatment is therefore inseparably connected with that usually resorted to in cases of threatened insanity, and embraces the employment of means moral as well as physical. Of these it is not my intention to speak ; I may observe, however, that Dr. Crawford has found opium, gradually increased to very large and frequently repeated doses so as to produce sleep, the best remedy. In the case of jaundice, the patient passed several nights without any sleep. He was just beginning to recover from the jaundice when this new symptom appeared, and I directed your attention particularly to the circumstance, because every manifestation of nervous derangement connected with jaundice should be carefully watched. It frequently happens that jaundiced patients sleep too much, and in some cases the disease is accompanied by convulsions, succeeded by coma, most alarming symptoms, and almost invaria- bly the harbinger of a fatal termination. Dr. Marsh was the first who directed our attention to the great fatality of those cases of jaundice in which convulsions occur ; I have seen but one instance of recovery. It was in the case of a gentlemen labouring under icterus, very considerable hepatitis, with enlargement of the liver and anasarca, with ascites. He was treated by Dr. Osborne and myself, and had at least a dozen long and violent convulsive paroxysms, ending in coma, succeeded by temporary forgetfulness and fatuity. Repeated leeching of the right hypochondrium, active purgation, and mercurialisation of the system removed all the symptoms of disease, and he slowly but perfectly recovered. A very able and original writer, Dr. Griffin, of Limerick, has detailed the particulars of some interesting cases of this nature in the Dub- lin Medical Journal. You perceive, therefore, that in jaundice every thing denoting an unusual state of the nervous system, whe- ther it be too much sleep or too little, demands your attention. In this man’s case the jaundice was the result of an attack of hepatitis. We treated it with leeches, blisters, and the use of mer- cury, and in the course of a few days the stools became copiously tinged with bile, and symptoms of improving health appeared. At this stage, the dejections being bilious, but the jaundice still remain- ing, he began to exhibit symptoms of restlessness and nervous irri- tability, and finally became perfectly sleepless. Here, gentlemen, we had to deal with a new symptom, extremely harassing to the patient, and likely to react unfavourably on the orginal disease. As a preliminary step I determined to evacuate the bowels, and for this purpose I prescribed a purgative draught, consisting of five ounces of infusion of senna, half an ounce of sulphate of magnesia, a dram of tincture of senna, and a scruple of electuary of scam- mony. My object was to purge briskly, and then give a full nar- cotic. In all cases of jaundice depending on hepatic derangement, after you have succeeded in producing bilious evacuations, you should never omit prescribing an active aperient every second or third day for the space of ten days or a fortnight, with the view of SLEEPLESSNESS. 27 carrying off the remains of the disease so as to prevent the occur- rence of a relapse. Hence you will find such cases very much improved by the use of Cheltenham water, taken every day for three or four weeks after the reappearance of a bilious tinge in the alvine discharges. The stimulus of the purgative causes an increased flow of bile into the intestines, which removes the hepatic congestion, and carries off what is popularly termed the dregs of the disease, and promotes a rapid and complete recovery. It is a simple but successful practice, and I would advise you never to omit its employment in cases of this description. With respect to purgative mixtures, I may observe that you should prescribe a larger quantity of the infusion of senna than is generally ordered, if you wish to secure its certain and decided operation on the intestines. Hospital nurses, who reason from facts and experience, know this, and when directed to give a senna draught they always give a small teacupful. They administer from four to six ounces at a time, and I have observed that in this way the action of the medicine is more certain, and the benefit derived from it more extensive. I am convinced that the usual mode of giving this valuable purgative in private practice is bad; the quantity given is too small, and consequently it is necessary to repeat the dose several times, a mode of proceeding apt to occasion much nausea and griping; I would therefore recommend a quan- tity varying from three to six ounces, to be administered in all cases where the patient’s condition will admit of free purging. A most accurate observer of the effects of medicines, Mr. Kirby, is in the habit of ordering purgative mixtures in chronic cases to be taken at bed-time, and not, as is usually done, in the morning. He asserts that their action is milder and less irritating to the bowels when the patient lies in bed and is asleep until the period of their opera- tion, than if he were up and about. After the purgative had produced four copious discharges, I pre- scribed eight minims of black drop, to be taken at a late hour in the evening. Whenever I give opiates to procure sleep, I always observe the rule laid down by Dr. M‘Bride (a celebrated physician of this city), to select the period at which nature usually brings on sleep, and which varies according to circumstances and the habits of the patient. Whenever you have to deal with watchfulness in patients labouring under morbid states of the constitution, as, for instance, hectic, enquire when the tendency to sleep usually occurs, and administer your narcotic about an hour or two before its occur- rence. It is between three and five o’clock in the morning that the inclination to sleep is strongest; it is about this time that sentinels are most apt to slumber at their post, and consequently attacks upon camps or cities, made with the intention of effecting a sur- prise, are usually undertaken about this period of the morning. How well marked is the periodic tendency to sleep at this hour in all patients labouring under hectic fever produced by whatever cause. How often do we hear the poor sufferer complain of rest- lessly tossing about in his bed until three or four o’clock in the 28 graves’s clinical lectures. morning, when at last sleep, welcome although uneasy, for a few hours separates the patient from his pains. If given at an early hour in the evening, the effect of the opiate is not coincident with this periodic attempt of the constitution, and it fails in producing sleep; but if exhibited at a late hour, it begins to produce its sporific effect at the very time when nature inclines the harassed sufferer to repose, and the result of these combined influences is a deep, tranquil, and refreshing sleep. By observing this simple rule, I have often succeeded in producing sleep in cases where various narcotics had not only failed, but even added considerably to the irritation and discomfort of the patient. In cases of sleeplessness, where you have administered an opiate with effect, be careful to follow it up for some time, and do not rest satisfied with having given a momentary check to the current of morbid action. To arrest it completely, you must persevere in the same plan of treatment for a few days, until the tendency to sleep at a fixed hour becomes decidedly established. You must give an opiate the next night and the night after, and so on for five or six nights in succession ; and where the watchfulness has been of an obstinate and persistent character, narcotics must be employed for a longer period and in undiminished doses. I do not allude here to the sleeplessness which accompanies confirmed hectic and other incurable diseases; such cases require a particular mode of treatment, and generally call for all the varied resources of medi- cine. But in those instances of watchfulness, which are frequently observed towards the termination of acute diseases, it is always necessary to repeat the opiate for some time after you have suc- ceeded in giving a check to this symptom. You need not be afraid of giving successive opiates lest the patient should become accus- tomed to them and a bad habit be generated, for the rapid conva- lescence and renewed health, which are wonderfully promoted by securing a sound and refreshing sleep, will soon enable him to dispense with the use of opiates. Another disease in which sleeplessness is a prominent symptom, is delirium tremens. We have had an example recently in our wards, and you have seen the means employed to overcome it. The patient came into hospital with symptoms of extreme nerv- ous excitement and watchfulness, which had continued for some time, and were brought on, as is most commonly the case, by repeated fits of intoxication, succeeded by a pause of perfect sobriety—in Irishmen the result of necessity or accident. In this man you must have remarked the signal benefit which attended the use of a combination of tartar emetic and opium, and how rapidly the watchfulness disappeared. I shall not enter into the details at present, as I purpose to return to this subject on a future occasion. There is, however, one form of nervous irritability, frequently observed in persons who are in the habit of drinking freely, but without running into excess, and presenting as it were a shadow of delirium tremens, on which [ shall make a few remarks. This SLEEPLESSNESS. 29 curious state of the nervous system is generally found to exist in men about the middle period of life, and who consume a larger quantity of spirituous liquors than they are able to bear. Such persons, without suffering in appearance, or losing flesh, get into a chronic state of disturbed health, manifested by nausea, and even dry retching in the morning, loss of appetite, and impaired diges- tion ; but in particular by a deranged and irritable state of the nervous system, and by watchfulness. This forms one of the most distressing symptoms, and the patient generally complains that he cannot get any sound and refreshing sleep, that he lays awake for hours together, and that when he slumbers his rest is disturbed by disagreeable dreams, or broken by slight noises. How are you to treat this affection ? I can give you a valuable remedy for this deranged state of constitution—one which I have often tried, and which, from experience, I can strongly recommend. It is a mix- ture composed of tincture of columbo, quassia, gentian, and bark— say an ounce of each; and to this is added a grain, or bven two, of morphia. A compound tincture, somewhat analogous to this, is much in use among military gentlemen, and others, who have resided for a considerable time in India, where, from the heat of the climate, and the prevalence of intemperate habits, the stomach becomes relaxed and the nervous system irritable, so as to repre- sent, in a minor degree, the symptoms which characterise delirium tremens. You perceive I combine several tonics to form this mix- ture, because they are well known to produce a more beneficial effect when combined than when administered singly ; and I add to these a narcotic, which has the property of allaying nervous excitement without derangement of the intestinal canal. The dose of this mixture is a teaspoonful three or four times a day, and the best time for taking it is about an hour before meals. It gradually removes the nausea and debility of stomach, lessens nervous irri- tability and watchfulness, and with a proper and well regulated diet, and attention to the state of the bowels, I have seen it produce excellent effects. In such persons much benefit is derived from the use of the tepid shower-bath. Fever is another disease in which sleeplessness is a symptom, frequently of an unmanageable character, and pregnant with dan- ger to the patient. You witnessed this in the case of the boy who lies in the small Fever Ward, next to the man who is at present labouring under general arthritis. This boy had fever of a mild description, and unattended with any bad symptoms. His case scarcely required any attention, and he had almost arrived at a state of convalescence without the aid of medicine, when he began to lose his rest, and absolutely became sleepless for several nights. I beg your attention to this case, for many reasons. In the first place, you have seen that we tried many remedies without success, and afterwards fortunately hit on one which answered our purpose completely. Let us examine the nature of the medicines prescribed, and our reasons for giving them. In the first place we gave, as in the case of jaundice, an aperient, 30 graves’s clinical lectures. followed by a full dose of black drop. It failed in producing any sleep; we repeated it a second and a third time, but without the slightest benefit. I then remarked to the class, that, as I had noticed the good effects resulting from a combination of tartar emetic and opium in the case of delirium tremens, where opium alone failed in procuring sleep, it would be proper to give this remedy a trial. I observed, at the same time, that I was convinced that the preparations of antimony have a distinct narcotic effect, and that I had seen patients in fever whose watchfulness had been removed by antimony given in the form of tartar emetic or James’s powder. I said it was my firm impression that tartar emetic, along with its other effects, exerts a decided narcotic influence on the system, and that it is this which makes it so valuable a remedy in treating the sleeplessness of fever and delirium tremens. Hence I have been in the habit of giving tartar emetic, combined with opium, in fever, and, I must add, with very great success. Our predecessors were much in the habit of using antimonial mixtures in the treatment of fever; and they did this because they knew, by experience, that these remedies worked well. It is at present too much the fashion to decry their practice, and in this instance, I think, with very little justice. In this boy’s case, however, the combination of tartar emetic and opium did not succeed in producing sleep. Having thus failed in our first and second attempts, we had recourse to the liquor muri- atis morphias—a preparation first brought into use by Dr. Chris- tison, and which, in the form usually employed, is equal in strength to laudanum. It is an exceedingly valuable preparation for many reasons, and one which has the strongest claims to your notice. Being of the same strength as laudanum, it saves the trouble of learning and remembering new doses, and, in addition to this, it possesses the more important advantages of inducing sleep with more certainty, and not acting as an astringent on the bowels, or affecting the head so frequently as laudanum. You observe that I say so frequently ; I do so because cases now and then occur in which even moderate doses of the liquor of the muriate of mor- phia produce quite as much headache as laudanum. I prescribed the former in doses of fifteen drops every six hours, so as to give sixty drops in the day, and continued this practice for two days, but without the slightest effect. Here you see three modes of inducing sleep completely failed. The boy remained for a day without taking any medicine, and then we made another attempt, which was more successful. We first prescribed a purgative enema, and after this had operated he was ordered an opiate injection, consist- ing of four ounces of mucilage of starch and half a dram of laud- anum. He fell asleep shortly after using the opiate injection, and did not awake until the next morning. The following night the opiate was repeated in the same form, and with equal success; convalescence went on rapidly, and the boy’s health is now quite re-established. Here, then, is a singular fact attested by this case, that opiates in SLEEPLESSNESS. 31 the form of injection will succeed in producing sleep, where they have completely failed when administered even in large and re- peated doses by the mouth. Baron Dupuytren was the first who made this important observation, and proved that narcotics applied to the mucous surface of the rectum exercise a powerful influence on the nervous system, always equal, and very often superior, to the effect produced by taking them into the stomach. He maintains that, in delirium traumaticum and delirium tremens, a certain quan- tity of opium, when prescribed in the form of enema, will act with more decided effect in allaying nervous excitement than the same, or even a larger quantity, when taken by the mouth. I have no hesitation in giving full credit to this assertion, as the results of my experience tend strongly to confirm its truth. I have, not long since, published, in the Dublin Med. Journal, the case of a patient in Sir P. Dun’s Hospital, who was reduced to the last stage of debi- lity and emaciation from the combined effects of mercury and syphilis. The torture which this man endured from nocturnal pains, and a total deprivation of sleep, was such that he swallowed enormous doses of opium; in fact, he had, previously to his admis- sion into Sir P. Dun’s Hospital, exhausted all his means in pur- chasing opium. While in hospital, he used to take 150 drops of black drop in the course of a day, and yet, notwithstanding these excessive doses, he could only get a few minutes of unrefreshing slumber. After some time I changed the plan of treatment, and had the black drop administered in the form of enema. It suc- ceeded in producing a decided soporific effect, and in a short time he was able to enjoy a sufficient quantity of repose, from taking only one tenth of the quantity used by the mouth. I have also, in the same paper, adverted to the case of a medical gentleman who laboured under an affection of his joints, which was accompanied by spasms of the limbs and most excruciating pains. His agony was so intense that he used to swallow grain after grain of opium, until he had taken to the amount of thirty or forty grains, with the view of procuring some alleviation of his sufferings. He was prevailed on to give up altogether the use of opium by the mouth, and employ it in the form of enema, which he did with the most striking advantage—the quantity which succeeded in giving relief in this way being scarcely the twentieth part of what he ordinarily used. It is unnecessary for me to enter here into any discussion with respect to the nature and treatment of delirium traumaticum, and the sleeplessness which always accompanies it, as you will find this subject very ably treated in M. Dupuytren’s works, and in a very instructive and elegant lecture delivered by Mr. Crampton (the surgeon-general) in this hospital, and published in the last volume of the London Medical and Surgical Journal. There isT however, one kind of sleeplessness, arising from irritation of the skin produced by blisters, which frequently assumes a very serious character, and on which it may be necessary to offer a few observ- ations, as the subject has not been noticed sufficiently by practical 32 graves’s clinical lectures. writers. Trifling as the irritation resulting from a blister may seem, yet, under certain circumstances, it is a symptom of highly dan- gerous aspect, and becomes a source of just alarm. I have wit- nessed the loss of some lives from this cause, and many patients have, to my knowledge, been rescued from impending danger, by an early and proper share of attention being directed to its pheno- mena and treatment. The bad effects on the nervous system, occasionally produced by the application of blisters, are somewhat analogous to those which result from wounds and other external injuries, and to be accounted for on the same principle. Wounds and injuries sometimes make an impression on the nervous system, by no means proportioned to the importance of the injured organ to life, or to the extent of the mischief. An injury, produced by a body which strikes the sen- tient extremities of the nerves with great force, will sometimes pro- duce very remarkable effects on the system. Thus, a musket-ball striking a limb may, without wounding any great artery or nerve, or destroying any part of importance to life, produce a train of nervous symptoms of an extraordinary character. The person, without feeling much pain, and scarcely knowing that he has been wounded, without being terrified or having his imagination excited by any apprehended dangers, turns pale, gets a tendency to faint, and sometimes actually dies from the impression made on the nerv- ous system. In the same way, an external injury reacting on the nerves may bring on high mental excitement, delirium, and a total privation of sleep, as we exemplified in delirium traumaticum. I mention this with the view of establishing the proposition, that impressions made on the sentient extremities of the nerves are sometimes reflected on the nervous centres, producing the most alarming effects. In this way we can understand how the irritation of blisters may produce sleeplessness, mental aberration, and a train of symptoms analogous to those which characterise delirium trau- maticum. The delirium and sleeplessness arising from the irritation of blisters is by no means an uncommon disease. I have seen many examples of it in private practice, and I am anxious that you should be acquainted with its nature and treatment. It is generally met with in the case of children, in whom the cutaneous surface is extremely tender and irritable. I could relate several instances in which I have been called on to visit children labouring under fever, where symptoms of high nervous excitement were present, and where I found the little patients delirious, screaming, and per- fectly sleepless from this cause. I have found this alarming affec- tion generally occurring at an advanced stage of fever, and exhibit- ing a train of symptoms which closely resemble hydrocephalus. I have observed that after the application of a blister to relieve some suspected cerebral or abdominal or thoracic affection, jactitation, restlessness, constant application of the hand to the head, and deli- rium have appeared, and that these symptoms had been mistaken for incipient cerebritis or hydrocephalus, and treated with leeches SLEEPLESSNESS. 33 and purgatives. When the blister has been applied to the nape of the neck, the soreness and irritation of the skin on that part cause the child to roll its head from side to side on the pillow, with that peculiar motion and scream, supposed to prove to a demonstration the existence of hydrocephalus. I have learned also, that the above measures, so far from giving relief, have only tended to produce an exacerbation of the disease, and that the medical attendant has given up the case in despair. Now, gentlemen, if called to such a case what should be your practice? In four cases of this kind I gave my opinion frankly to the medical attendant, and told him he was pursuing a wrong course, that the disease was analogous to delirium traumaticum, and not to be treated by leeches or purga- tives, and least of all by blisters. I observed to him that these symptoms had made their appearance shortly after the child had been blistered for suspected disease of the belly, or head, or chest; and that it was useless to attempt to remove the disease by leeches, or purgatives, or blisters. The remedy I always proposed was opium, and it was acknowledged in four or five cases, that this remedy had succeeded not merely in relieving the existing symp- toms, but in saving the patient’s life. In such cases, particularly in young children, the opium must be given in small but frequently repeated doses, so as to ensure its energetic but safe action, and the greatest care must be taken to soothe the irritated portion of the skin by ointments, poultices, &c., while unwearied diligence must be bestowed upon the task of preventing the child from scratching the blistered surface. To effect this the child’s hands must be muffled in appropriate gloves, and must be secured in the sleeves of a shirt made for the purpose. I beg your attention still further to this subject of sleeplessness and delirium. I wish to mention the case of a gentleman who was a pupil of mine. This gentleman studied hard, attended lectures regularly, and was constantly in the dissecting room. While thus occupied, he happened to wound one of his toes in paring a corn, and afterwards wore a tight shoe on the injured foot. A small imperfect abscess formed in the situation of the corn, which was opened by one of his fellow students ; the incision gave very great pain, and was not followed by any discharge of matter. Next day he was feverish, and the lymphatics of the injured limb became extensively engaged, the inflammation ascending towards the glands of the groin and having a tendency to form a chain of insulated patches in different parts of the leg and thigh along the course of the lymphatics. This you will generally find to be the case in inflammatory affections of the lymphatics; the inflamma- tion is seldom continuous, but, in the majority of cases, is developed at certain insulated points, where small diffuse suppurations form very rapidly. After a few days, this young gentleman’s fever increased to an alarming height, he became completely sleepless, and had incessant delirium. He was purged briskly, leeched ex- tensively and repeatedly, his head shaved, and cold applications so constantly applied, that he appeared half drowned and collapsed. 34 graves’s clinical lectures. Notwithstanding this very active treatment not the slightest relief was obtained; neither were the symptoms mitigated by incisions made in the inflamed patches for the purpose of evacuating matter; the sleeplessness continued, and the delirium was as wild as ever. 1 saw him on the seventh or eighth day, when all antiphlogistic measures had failed, and his friends were quite in despair. On being asked my opinion, 1 stated that I looked upon the case as one of delirium, not proceeding from any determination to the head or inflammation of the brain, but depending on a cause analogous to those which produce delirium traumaticum, and that instead of antiphlogistics I would recommend a large dose of opium and some porter to be immediately given. Mr. Cusack, who visited the patient after me, concurred in this view, and a full opiate was administered in repeated doses. It succeeded in producing sleep and tranquilising the nervous excitement. I may here observe that a few days afterwards this gentleman had a return of the symptoms of cerebral disturbance with sleeplessness, in conse- quence of omitting his opiate, and that the opiate and porter were again administered, and again succeeded in removing the delirium and watchfulness. By perseverance in the use of the same means, the disease was completely removed, and convalescence established. The last kind of sleeplessness to which I shall direct your atten- tion, is that which is frequently met with in persons of a nervous and irritable disposition, in hypochondriacs and hysterical females. You will find such persons, although of active habits and with tolerable appetites, complaining of a total privation of their natural rest, and it is astonishing to think how long they may continue subject to this harassing watchfulness. I have frequently observed this affection among females of nervous habit, who possessed strong feelings of attachment to the interest and welfare of their families, and who were remarkable for an exemplary and over anxious dis- charge of their domestic duties. It is also very often met with in the upper classes of life, where the susceptibility to nervous excite- ment is morbidly increased by fashionable habits. I shall not enter into the various moral causes which tend to produce this state of the nervous system, and will content myself for the present with giving you some hints for the treatment of this obscure affection. As yet I have not any distinct and accurate notions of the disease, and can only guess at the treatment; but this much I may state, that such cases are not to be cured by the means which I have already detailed. If they are to be cured by any means, I think it is by antispasmodics, and remedies which have a gentle stimulant, and, if I may so express myself, alterative effect on the nervous system. I have cured two cases of this kind by musk and assafoetida, where every other remedy had failed. To one of these I was called by my friend, Dr. Neason Adams; the patient was a lady of delicate constitution and hysterical habit; she was emaciated, and suffered from a total loss of rest, but had no other disease. All kinds of narcotics had been tried unsuccessfully, and opium in all its forms had failed in procuring sleep. I advised the use of musk in doses SLEEPLESSNESS. 35 of a grain every second hour, and this means proved eminently successful. In another case I succeeded by administering the same remedy in combination with assafcetida. I have also remarked that assafcetida alone, given in doses of two or three grains three times a day, has very considerable effect in calming nervous irrita- tion of this description, and restoring the patient to the enjoyment of more prolonged and refreshing sleep. In all such cases the phy- sician must be most careful to have the appearance of not thinking the loss of sleep as a matter of much consequence, and the family of the patient must be directed to speak as little about the matter in his presence as possible;—nay, so powerful is the operation of moral impressions, that in one case, which I attended along with Mr. Halahan, I succeeded in procuring sleep by ordering a musk pill to be given every second hour night and day, and by desiring the patient to be awakened, should she be asleep, at the time the pill was to be taken. I laid great stress on the importance of so proceeding, and thereby produced so strong an effect on the patient’s mind, and inspired so great a confidence in the efficacy of the medi- cine, that she went to bed, not so much afraid of lying awake as afraid of being asleep at the hours when she ought to take a pill. The idea which had hitherto fixedly occupied her mind was dis- placed by a new impression, and relief was obtained the very first night. In affections of the head occurring in acute diseases, and attended with raving and loss of rest, it is a very usual practice to direct the application of cold lotions to the shaved scalp. Permit me, gentlemen, to make a few remarks upon this im- portant subject. I wish I could make myself well understood on this point, for I have seldom met with any person who seemed to bear in mind the true principle upon which cold is applied as a means of repressing local heat. In cases of determination of blood to the head occurring in fever, the common practice is to have the head shaved and cold lotions applied. Enter the room of a patient who is using cold applications, and you will observe the process conducted with great apparent nicety; the head is accurately shaved and carefully covered with folds of linen wet with a lotion to which spirit of rosemary or some odoriferous tincture has communicated an agreeable and refreshing smell; but when you come to examine the patient, you find his head smoking and the heat of his scalp increased. The nurse applies the lotion once every half hour, or perhaps not so often ; indeed, she seldom repeats the application until her notice is attracted by the steam rising from the patient’s head, or until she herself, awaking from a comfortable sleep, and going over to examine the state of the patient’s head, find the folds of linen which cover it as hot and dry as if they had been hung before a fire. Whether applied to reduce local inflammation in any part of the body, or to cool the scalp in determination to the head, cold lotions as ordinarily em- ployed do infinitely more harm than good. The cold is applied at distant intervals, its effect soon ceases and reaction constantly 36 graves’s clinical lectures. takes place, leaving the part as hot or even hotter than it was before. If you put your hand into snow for a few moments and then take it out, it quickly resumes its natural heat; and if you repeat this at considerable intervals, so as to give time for reaction to occur, the vessels assume a more energetic action, and it becomes hot and burning. If you continue to keep it in the snow for a long time, its heat becomes completely exhausted, reaction does not take place until after a considerable period, and very slowly, and the hand remains at a very low temperature for a good while. Bear this in mind, for it will direct you in the application of cold to reduce local heat. If cold applications be used at such intervals as to allow the scalp to react and resume its heat, rely upon it, it is much better to forbid them altogether. Where you wish to apply cold with effect, let it be done by relays of folded linen, wet with any frigorific mixture, and repeatedly applied to the scalp so as to leave no smoking, or, what is much better, get three or four blad- ders, put into each a quantity of pounded ice, and apply one over the crown of the head, one on each side, and lay one on the pillow for the back of the head to rest on. There is a vast difference between a thing being done and its being well done: so it is with regard to cold lotions ; so difficult is it to ensure their proper application, that I have entirely given them up in hospital practice, and rarely order them in private. I have been induced to abandon them in consequence of witnessing so many instances in which my directions were neglected, and con- sequently the cerebral congestion was augmented by their mal- application. Another serious inconvenience frequently arises from their use when applied in a slovenly manner, which is the danger of cold arising from the pillow and bed-clothes being wetted. It is a curious fact that the head is the only one of the three cavities with respect to which long established custom has laid down the maxim, that when its contents are inflamed we may cool the surface over it, while in inflammatory affections of the thoracic or abdominal viscera this practice is avoided as dangerous and inapplicable. Latterly, however, some medical men have been inclined to question the grounds on which cold applications have been rejected in the two latter cases, and some have even declared that they have used ice poultices in inflammations of the chest and belly with great success and perfect safety. I am not as yet pre- pared to adopt this practice, although I must confess that a review of the subject might incline me to give up my prejudices on this point. It is certainly but reasonable to think that what is true of the one may be also true of the other, and that the application of cold to the head and heat to the chest and belly has nothing in its favour beyond mere custom. It should be recollected, however, that the head and face are more accustomed to cold than the chest and belly, and hence are less liable to any mischief likely to arise from its application in an intense degree. Still I am inclined to think that there is much prejudice connected with the practice of COLD APPLICATIONS. 37 applying cold to the head; and I have very little doubt that if the matter was properly investigated, and a number of experiments made, it would lead to the abandonment of cold applications in most inflammatory diseases of the brain. In fevers, I can say positively that in the majority of cases they are positively injurious, as usually applied; sponging the bare scalp with tepid or warm vinegar and water, or even frequently repeated steeping of the head and tem- ples, will often succeed much better in abating the headache and restlessness of fever than any cold applications whatsoever. In 1832, a violent influenza, accompanied by most distressing head- ache, attacked thousands in Dublin ; this intense pain in the head was relieved by nothing so effectually as by diligent steeping of the temples, forehead, occiput, and nape of the neck, with water as hot as could be borne. I do not speak here of the application of cold to the head for the purpose of relieving local heat and inflammation, but to produce an effect on the whole system. Cold thus applied is of decided and unequivocal value. You are aware that in cases of fever accom- panied by symptoms of high mental excitement and great heat of skin, the use of cold dashing has produced the most extraordinary effects. Again, if a patient has taken too large a dose of prussic acid or any other narcotic, the best mode of rousing him is by pour- ing water on his face or chest from a height. In Turkey, if a person happens to fall asleep in the neighbourhood of a poppy field, and the wind blows over it towards him, he becomes gradually nar- cotised, and would die, if the country people, who are well ac- quainted with this circumstance, did not bring him to the next well or stream, and empty pitcher after pitcher on his face and body. This occurred to my friend, Dr. Oppenheim, during his residence in Turkey, and he owes his life to this simple but effectual treatment. To conclude, gentlemen, I may observe that sleeplessness in a chronic form is often produced by dyspepsia, and can only be relieved by the means suited to indigestion. Here it is that small doses of blue pill and tonic purgatives are of infinite service, com- bined with change of air, of scene, and an appropriate diet. In many females, sleeplessness is combined with menstrual irregularity, and can only be cured by means calculated to invigorate the health and restore the catamenial discharge to its natural periods and quantity, for the nervous system suffers equally whether they be suppressed or over abundant. It is singular how long sleeplessness often continues in chlorosis without inducing those serious conse- quences that are produced by this symptom in other morbid states of the system. In such cases much is sometimes accomplished by means of the common preparations of morphia, or by the use of Hoffman’s liquor (liquor asthereus oleosus), camphor, and other medicines that act upon the nervous system. It must be confessed, however, that these and every other expedient to obtain sleep often fail in chlorotic and hysterical females, in whom relief is only obtained by a gradual improvement of the general health and menstrual function. 38 graves’s clinical lectures. LECTURE IV. GANGRENE AND PLEURITIS. I have here the lungs of a patient who died yesterday in the fever ward, and to whose case I have frequently directed your at- tention. They present some pathological phenomena of consi- derable interest, and I would advise you to examine them carefully after lecture. The patient, who was advanced in life and of a feeble constitu- tion, had been ill for a week before his admission, with symptoms of dyspnoea, cough, and pain in the left side, which appeared shortly after his recovery from an attack of fever. On examining him the morning after his admission, we found the interior part of the left lung dull on percussion, the dnlness extending much higher up posteriorly than anteriorly. On applying the stetho- scope, we observed that, over a space about the size of two palms, no sound, morbid or otherwise, could be heard ; but above the line which bounded this space there were crepitating rales and bronchial respiration. We had, therefore, a twofold affection of the lung, pleuritis, as indicated by the pain in the side, dulness on percussion, and absence of all sound over a certain portion of the chest; and pneumonia, as indicated by cough and expectoration of viscid sputa, tinged with blood, dulness of sound on percussion, bronchial respiration, and crepitating rales. It is unnecessary for me to reca- pitulate all his symptoms, as I have, while visiting the wards, mentioned them in detail, and I shall merely state, that our exami- nation showed that this man, in the first place, was labouring under pleuritis, and that it was of that kind which is called dry pleurisy, and where there is no tendency to considerable effusion ; and, in the next place, that he had pneumonia of the inferior lobe of the left lung, extending up into the middle lobe posteriorly. You will recollect that, at the time of our examination, I marked on his skin with a pen the extent of the pleuritic inflammation as well as of the pneumonia, and you will find, by examining this lung, that my diagnosis was correct. You will observe the pleura presenting, over its inferior part, laterally and posteriorly, an effusion of lymph, with a very small quantity of sero-purulent fluid ; and here is the seat of the pneumonia, which occupied precisely the portion I pointed out and no more. With respect to treatment, it was antiphlogistic, pushed as far as the advanced stage of the disease and the age and debility of the patient permitted. He was leeched and blistered, and this was im- mediately followed up by the use of calomel and opium, and the application of mercurial ointment over the affected portion of the chest. This treatment appeared to check the disease and stop the progress of disorganisation in the lung ; at least it certainly arrested the pleuritis. The pulse became more tranquil, and what encou- raged us to entertain some slight hopes was, that the difficulty of GANGRENE AND PLEURITIS. 39 breathing subsided, and respiration became less frequent, although it was never reduced to any thing like the natural standard. I have already told you, that in studying acute and chronic affections of the chest, the two chief symptoms to be attended to, are the num- ber of respirations which occur in a minute, and the amount of dyspnoea complained of by the patient. Here, though the respira- tions sank from forty to thirty, still they were nearly double the natural frequency; and this, coupled with the age and debility of the patient, forbade us to hope for a cure. Though the pulse had become more tranquil, and the bloody expectoration had ceased, though dyspnoea was no longer complained of, and the frequency of respiration had become reduced, still the man’s countenance ex- hibited strong marks of suffering and debility, and the stethoscope showed that the disease still continued, and there was no tendency to resolution in the affected lung. Here the stethoscope was of great value. A person ignorant of its use, observing the tranquil state of the pulse, the diminution in the frequency of respiration and the cessation of dyspnoea, might be led to believe that the man was getting better, and to pronounce that the period of convales- cence was near. But the stethoscope told us that the hepatisation of the lung had no tendency to resolution, and when we observed, after a week, that it was still undiminished in extent, we were led to form an unfavourable prognosis. We knew that matters could not remain long in this state ; we knew that the disorganised lung acted as an irritant tending to keep up disease, and that the man was every moment liable to a fresh attack of inflammation. In the mean time the patient caught a fresh cold, from being exposed to the thorough air of our too well ventilated wards. This fell on his larynx, producing hoarseness, stridulous breathing, and copious expectoration. When an old person, reduced by some previous disease, catches cold, and gets, in consequence, a sudden and remarkable hoarseness, so that he can only speak in whispers; when, in addition to this, he has cough, stridulous breathing, and copious muco-purulent expectoration, you may be sure that the case is a bad one, and the patient in most imminent danger. In- flammation of the larynx in children is, you all know, a violent disease, it terminates in an effusion of lymph which, if not pre- vented, or remedied, by the most prompt and decided measures, too often produces fatal obstruction to the entrance of air, and death from asphyxia. In the adult, laryngitis does not, except in a very few instances, cause an effusion of lymph; still it is a severe disease, and well calculated to excite alarm. In the aged it is accompanied by considerable fever, and, what you would suppose likely to give relief, copious expectoration, evidently derived from the larynx itself;—and yet I do not recollect that I have ever seen a case of this kind that did not terminate fatally. I have very recently visited a case of this description, which occurred in the person of an eminent country practitioner, who had jyst come up to Dublin. He got an attack of cold, followed by hoarseness, which went on for two or three days without being attended to, until one evening 40 graves’s clinical lectures. he suddenly became alarmingly ill, and was obliged to send for his friend, Dr. Evanson, who prescribed and called on me the next day. I found him labouring under stridulous breathing, constant laryngeal cough, prostration of strength, and enormous muco- purulent expectoration. His pulse was very rapid, he complained much of oppression of the chest, and died the following night, more with symptoms of exhaustion than of asphyxia. The symptoms of laryngitis, which arose thus suddenly in our patient, were quickly succeeded by others. On Saturday morning we found him much worse, his countenance was sunk and livid, and his breath had become extremely fetid. His expectoration also exhibited a very remarkable change ; it was greenish, ichorous, and had a most intolerable fetor. He now began to manifest symptoms of awful prostration, his distress of respiration became intense, his eyes fixed, his extremities cold, and he expired in about forty hours from the commencement of the attack. Here, gentlemen, a man, after fever, gets an attack of pleuro- pneumonia, this is relieved to a certain extent by treatment, but the hepatisation remains unresolved. At the end of three weeks he gets an attack of laryngitis ; in addition to this, gangrene seizes on the diseased lung, and he sinks with great rapidity. Where gan- grene attacks the limbs it may creep on slowly, and life may be prolonged for a considerable time, but when it fixes on internal organs its course is rapid, and generally proves fatal in a few days. In the lung, unless the patient’s constitution is unimpaired and the disease limited, it will terminate quickly in death, and you have seen that, in this case, it only lasted from Saturday until Monday morning, that is to say about forty hours. After the acute stage of pneumonia had passed away, as denoted by the absence of fever and bloody sputa, and diminution of dyspnoea, and frequency of respiration, the case assumes a chronic character, which continues for nearly a fortnight, and then a new order of symptoms appears, manifested by fetid breath and expectoration, sudden prostration of strength, Hippocratic face, and cold extremities. Those who have watched this case must have been struck with these three remark- able stages : the first stage of inflammation, the succeeding one of chronic disease, and the termination in gangrene. It is not usual to find gangrene of the lung supervening on inflammation which is arrived at the chronic stage ; it is most commonly the result of acute inflammation of intense character, and comes on at a very early period of the disease. How are we to account for this sudden supervention of gangrene ? There was nothing in the nature of the pneumonic inflammation to dispose it to terminate in this way. It had lasted for three weeks, and had arrived at a stage in which inflammation very rarely assumes the gangrenous character. To what, then, are we to attri- bute it ? Partly to the debility of the man’s constitution, and partly to an erysipelatous tendency in the air, which is now very prevalent. Except there was something to dispose the lung to gangrenous disease, as an enfeebled habit and a vitiated quality of atmosphere, GANGRENE AND PLEURITIS. 41 we could not, under the existing circumstances, have expected such a termination. That this view of the subject is correct, is shown by the simultaneous occurrence of gangrene in another part, which had not been previously diseased, or subject to inflammation, except shortly before the man’s death,—I allude to the larynx. If you examine the larynx you will find the mucous membrane at the posterior surface, and where it invests the chord® vocales, destroyed by gangrenous sloughing. You perceive, then, we had gangrene in the larynx and lung, simultaneously. The gangrene of the lung was not therefore attributable to the occurrence of local in- flammation having a tendency to gangrene, but dependent upon a constitutional affection produced by debility and a vitiated state of atmosphere. If this man had chanced to get a wound on any part of his body, T have no doubt but that it would exhibit a gangrenous character, and, in the same way, if he happened to get inflamma- tion of the bowels, it is most probable that this also would have ended in gangrene. I have frequently, in the advanced stage of fever, where the patient is much reduced, and where signs of a morbid condition of the fluids are present, seen gangrene occur simultaneously in various parts of the body. What I wish to impress on you is, that though the inflammation of the lung ended suddenly in gangrene, it was not in consequence of the inflamma- tion having in itself any such tendency, but in consequence of a change produced in the man’s constitution by atmospheric influence, and which was favoured by his advanced age and great debility. The inference to be drawn from the sudden occurrence of gan- grene in this case is, that it does not depend merely on violence of inflammation. At one time pathologists were inclined to believe that gangrene was invariably the result of excessive inflammation, or at least of inflammatory action disproportioned to the vitality of the parts attacked, and that it was possible to prevent any inflam- mation from ending in gangrene by prompt and active treatment. But there are certain states of the constitution which have a ten- dency to convert every form of inflammation into gangrene, and that wholly independent of the violence of the local inflammatory action. Thus, a person reduced by fever, small-pox, or malignant scarlatina, becomes liable to be attacked with gangrene in various parts of the body from the slightest causes. In all parts which are exposed to any degree of pressure, you will, under such circum- stances, have gangrenous sores formed; and. even in parts where no degree of pressure has been exercised, sphacelus is not unfrequently produced, as we see in many cases of confluent small-pox, and in the mortification of the pudenda in female children, which some- times occurs in bad measles. In such instances, gangrene is not preceded by symptoms of inflammatory action; and. in the present case, it is very probable that no inflammation of the lung, properly so called, preceded the gangrenous affection which terminated life. Permit me now to direct your attention to the case of a man named T. Kelly, who lies in the upper fever ward, and has been under the care of Mr. Knott. He is at present labouring under an 42 graves’s clinical lectures. attack of pleuritis and pneumonia, each modifying the other—the pleuritis being here also of that nature which is, by contra-distinc- tion, termed dry. A few particulars in this case demand our notice. In the first place, from looking at this man and examining his pulse, you would never suppose that he was labouring under a formidable disease. A careless observer, finding the pulse to be soft, regular, and only seventy-two in a minute—that respiration was tolerably free, and the skin cool—might here very easily overlook the true nature of the disease, and say this man has no fever, no inflamma- tion of any internal organ. Yet a careful examination shows that the right lung and pleura are extensively engaged. In the next place, we find that the pleuro-pneumonia has attacked the upper part of the lung instead of the lower. Pneumonia has a great ten- dency to attack the lower and posterior parts of the lung; indeed, so frequently do we meet it in this situation, that we look upon its occurrence in the upper part of the lung as a rare exception to a general rule. The third point connected with this case is, that, though the patient is labouring under pleuritis and pneumonia, his blood does not exhibit the slightest symptom of being affected by this combination of violent inflammations. When drawn from the arm, it separated very imperfectly into crassamentum and serum, and there was no deposition of that buffy coat which has been so often noticed by our ancestors as occurring in pleuritis, and hence termed crusta pleuritica. Here, from observing that there was no formation of coagulum—no cupped or buffed appearance in the blood, and that the pulse was soft and regular—some persons would have argued that no inflammation was present; but how false and dangerous such a conclusion would be, any one may convince him- self by making a careful stethoscopic examination. The fourth point (which was first observed by Mr. Knott) is, that there is a considerable disproportion in the size of the sides of the chest; the right side measuring better than two inches and a half more than the left. Now, there must be some cause for this ; and as the man has pleuritis on this side, it would be natural to infer that there is a considerable effusion of fluid in the cavity of the pleura, and that the dilatation of the side is produced by empyema. There are some circumstances, however, in this case which forbid us to adopt such a conclusion. In the first place, this great increase of size in one side of the chest would indicate a very considerable effusion. By empyema, I do not mean the effusion of a quantity of lymph, which does not push back the lung more than a line, but an effu- sion of fluids of various densities, and in large quantity, exercising very considerable pressure on the lung, and pushing it back towards its root. There are two circumstances in this case which should be attended to; first, the man is a labourer, and in such persons the chest, measured across the pectoral muscles, is always found to be on the right side half an inch, and sometimes nearly an inch, larger than it is on the left. This is accounted for by the increased development of the muscles of the right side from constant use. In the next place, we find that this man has not only pneumonia GANGRENE AND PLEURITIS. 43 and pleuritis, but also a tendency to superficial inflammation occu- pying the parietes and integuments of the chest, as indicated by a feeling of pain and soreness in various regions of that side, but particularly at the lower part, where the sound is clear on percus- sion. Now, where the sound is clear on percussion, you are aware that no effusion of fluid exists. The fact is, that, in addition to pleuritis and pneumonia, the man is labouring under pleurodynia, with a tendency to inflammation in the superficial parts of the chest. Under these circumstances, we should not be surprised to find some oedema of the parts; and here we have a second cause for the greater measurement of the right side of the chest. These are the only points connected with this case to which I shall advert at present, except to mention that the treatment was obviously indicated to be antiphlogistic. You might perhaps think that in treating this man it was a matter of indifference whether you had recourse to tartar emetic, either alone or in combination with nitrate of potash, or to calomel and opium; but you may lay it down as a rule now firmly established, that, in cases like this, the mercurial plan answers much better than tartar emetic. After bleeding this man, then, we gave him mercury in such doses as to affect his system as rapidly as possible, and we followed up our general means of depletion by the application of leeches, which, in all inflammatory affections of the chest, are indicated in propor- tion to the pain and tenderness of the chest complained of by the patient. Indeed, something similar must guide us in judging how far we are likely to procure relief, in cases of inflammation of any internal organ, by means of the application of leeches to the sur- face over the organ affected. No good is ever obtained by their application, unless tenderness or soreness on pressure be distinctly observable, and the relief obtained is always proportioned to the diminution of this tenderness where it existed ; where it does not exist, the application of leeches only leads to loss of time, and we must employ other remedies in such cases. There is another symptom in this case which might deceive you into the belief that empyema is present; the motions of the right side of the chest are much more limited than those of the left. When you look at him stripped, you perceive an obvious difference between the respiratory motions on each side; the motions of the unaffected are free, and much more extensive than those of the dis- eased side. Now, generally speaking, this is a symptom most com- monly observed in empyema and a few other diseases. It may also exist where there is extensive hepatisation of one lung, for, in proportion to the impossibility of air entering the diseased lung, will the motions of the corresponding side of the chest be dimi- nished. How are we to account for it in this man’s case ? The pneumonia is not extensive enough to cause it. and we have no evidence of the existence of any effusion into the pleural sac suffi- cient to explain it. The only way we can account for it is by recollecting that the man has pleurodynia; and, as every attempt at dilating the chest gives him pain, he endeavours to control its 44 graves’s clinical lectures. motions oil that side as much as he possibly can. This is a fact well worthy of notice. It exhibits to us a beautiful provision of nature, which enables a person, by an intense discharge of the respiratory function in one lung, to compensate himself for a limited and imperfect performance of it in that half of the chest where it is limited by pain, paralysis, or disorganisation. As I am on the subject of pneumonia, it may be necessary to make a few remarks on some points connected with it, and first with respect to the expectoration. With the characters of true pneumonic sputa, I suppose, you are sufficiently acquainted; you had many opportunities of examining the expectoration of the pa- tient who died of gangrene of the lung at the time he was labour- ing under acute pneumonia, and while hepatisation was still going on. But I wish to observe—and I beg you will impress this on your minds—that there may be cases of extensive pneumonia without any expectoration from the commencement of the disease to the period of complete resolution. A case occurred in this hos- pital, of a young woman, named Mary Nowlan, who had half one lung and the lower third of the other hepatised during a severe attack of pneumonia, and yet it was not accompanied at its com- mencement by expectoration ; there was no expectoration during its continuance, and resolution went on, and the was restored to its healthy condition without any expectoration. She remained in the hospital for two months, the lung being extensively engaged; and during this time she was carefully watched, but we never could discover any thing like sputa from the beginning to the end of the disease. This is a very singular but instructive case. Another fact with regard to expectoration. A man may get an attack of pneumonia, and, in consequence of the rush of blood which accom- panies the first access of inflammatory action in the lung, may have at the beginning some bloody expectoration, but after a day or two this subsides ; and though the lung is extensively engaged, the pa- tient may not have any expectoration whatever throughout the whole course of the disease up to the period of total resolution. I have seen this occurrence most distinctly marked in a case which I attended with Dr. Marsh. A gentleman, who had got an attack of acute pneumonia, had bloody expectoration for the first and second day, but on the third, when I saw him, it had ceased, and all expectoration continued absent for five weeks, at the end of which he completely recovered. He was an intelligent and scien- tific man—knew well what was the matter with him, and enter- tained the old notion that all inflammatory affections of the lungs resolve themselves by expectoration. Hence he looked day and night for its occurrence with considerable anxiety, but not the least sign of sputa appeared. In this case the hepatisation, which was very extensive, became completely resolved in the course of five weeks, and yet it is a singular fact that there was no expectoration whatever, from the commencement of resolution to its termination. Hence you may perceive, that in pneumonia the sputa may be absent from the beginning to the end of the disease; and that, HEPATISATION OF THE LUNG. 45 though the hepatisation may be very extensive, still resolution will occur without the slightest expectoration. Again, inflammation may attack a considerable portion of the lung, and the patient may have bloody expectoration for the first two or three days, or during the stage of congestion ; this may cease altogether, and the patient have no sign of sputa of any description up to the period of com- plete resolution. These are, no doubt, rare exceptions to the gene- ral law which regulates the course of pneumonic inflammation, in which we have sputa of one kind or other at every period of the disease; but they possess a considerable degree of interest, and it is of some importance to be acquainted with them. Allow me to repeat here an observation I have already made. The lung becomes attacked by inflammation, this goes on to hepa- tisation, that is, a certain portion of the pulmonary tissue which had been before pervious, becomes impervious ; instead of being a soft, elastic, crepitating, sponge-like body, it becomes solid, inelastic, and very like that organ from which this condition derives its name, the liver. One of the most curious things, the knowledge of which we have arrived at by the discovery of the stethoscope, is, that not only small, but even very extensive, portions of the lung may become thus solidified and altered in their texture, so that a return to the normal condition would seem almost impossible, and. yet we know that a person may have nearly two thirds of one lung reduced to this state of solidification, and still become after- wards as-healthy as ever. Now, if you read Laermec’s admirable remarks on pneumonia, and other treatises on the same subject, you will find that the circumstances which indicate the resolution of pneumonia, are sputa of a certain character, and the reappearance of crepitus. I need not repeat here what I suppose you are all aware of, that crepitus commences before hepatisation, ceases on’'its appearance, and returns again when resolution take place. The latter kind is what has been termed by Laermec, crepitus redux. Nature accomplishes the resolution of pneumonia not only by ab- sorption of those particles which the process of morbid action has deposited in the tissue of the lung, but by secretion into the air cells and minute bronchial tubes, and it is the presence of this secretion which gives rise to the crepitus redux. Now, the obser- vations which T have made with respect to the total absence of expectoration in some cases of pneumonia, apply here also; for where all sputa are absent, where there is no expectoration from the be- ginning to the end of the disease, you can have no crepitus redux. This observation I have made in several cases. The fact which I wish to impress on your attention is, that in some cases of pneu- monia expectoration may be completely absent; here the crepitus redux is never heard. Thus, in the case of Mary Nowlan, resolu- tion went on to the re-establishment of the healthy and normal condition of the lung, without the slightest crepitus being heard. The same thing has been observed in two or three cases by my friend Mr. Dwyer. It is not necessary for the resolution of hepa- tisation, that there should be increased excretion into the bronchial 46 graves’s clinical lectures. tubes, during the time nature is employed in absorbing the matter deposited in the lung. In the ordinary way it is removed partly by absorption and partly by excretion into the bronchial tubes. Sometimes, however, interstitial absorption alone seems to be suffi- cient for this purpose, and the cases I have mentioned prove that it is in the power of nature to remove the morbid product in this way, without calling in the aid of the bronchial tubes. I may, however, remark that such cases are rare, and that resolution proceeds much more slowly than where free expectoration is present. Before I conclude, I wish to make a few observations on a case of erysipelas which has recently occurred in our wards. Indeed we have had within the last two days three cases of erysipelas, the disease, in two instances, attacking patients who lay close to each other. Erysipelas is at present epidemic, and has been so for some time. Its character and mode of treatment have been well de- scribed by Mr. M‘Dowel, in a late paper, published in the Dublin Medical and Chemical Journal, which I would recommend you to peruse attentively. It has been observed by Ur. Cusack and others, that when erysipelas prevails as an epidemic we may expect puerperal fever, and scarlatina of a bad and dangerous type. Hence it would appear that the same noxious quality of atmosphere which generates one disease, may give additional malignity to others. One of these cases of erysipelas occurred, in the fever ward, under peculiar circumstances. A young woman was admitted some time ago, labouring under spotted fever; she had been many days ill before her admission, and continued for a considerable time in an uncertain state. It is unnecessary for me to enter into any details regarding her treatment; but after the more obvious indica- tions were answered, she was ordered to use the liquor chlorid. sodae, and became convalescent, or quam proxime so. Her tongue began to clean, the abdomen was soft, the bowels natural, the skin cool, and the pulse about eighty. One evening she got fresh symp- toms of fever, raved during the night, and next morning, when we visited the wards, we found her pulse accelerated, her tongue dry, black in the centre, and dusky red at the edges and tip, and, in addition to this, she had some diarrhoea. The nostrils were filled with a semicoucrete mucus, exhaling a most offensive odour ; in fact, one could hardly approach her bed without experiencing nausea from its extreme fetor. The inside of the nares was red and swollen ; in short, erysipelas was seen occupying the nose, upper part of the face, and forehead. It had first attacked the skin and subcutaneous cellular tissue, producing considerable oedema, and from this it had extended to the mucous membrane of the nose. Erysipelas generally commences in the skin, but sometimes it has its origin in the mucous membrane. I need not tell you that erysipelas of this oedematous character, accompanied by such a remarkable change in the secretion of the nostrils, and occurring in a person weakened by fever, was to be looked upon as a dangerous disease. I have not time to enter into any further observations on this subject, and will proceed at once ERYSIPELAS. 47 to mention our plan of treatment. How did we treat this case? Not by the usual antiphlogistic means, for the patient was greatly debilitated. Blood-letting, leeching, emetics, and purgatives, were here out of the question ; however valuable they may be in ordinary cases, we could not use them here without risking the patient’s life. You might think that an emetic or a purgative could do very little harm, and might effect much good, but you are to recollect that the girl had nausea, thirst, bowel complaint, and great prostration of strength. What then was to be done ? First, we applied a blister to the nape of the neck, to act partly on the brain and pre- vent delirium, and partly on the erysipelatous inflammation of the nose and forehead. How blisters act in this case I do not exactly know, but you are all aware that a blister applied in the neighbour- hood of a patch of this kind of oedematous erysipelas, is often fol- lowed by very good effects. Whether it is by exciting a new irritation, or by directing the current of the cutaneous circulation to another part, and causing a flow of serum thither, I cannot tell, but blisters certainly do give very considerable relief. So much for external means. Now with respect to internal, the only one we could give here, with any prospect of benefit, was the sulphate of quinine. But the patient had nausea, thirst, and diarrhoea, and if you administer quinine by the mouth, under such circumstances, you will do more harm than good. I therefore prescribed it in the form of enema, directing five grains of quinine, combined with four of tincture of opium, and two ounces of mucilage of starch, to be thrown up the rectum every fourth hour. Under this treatment the girl began to improve rapidly, the erysipelas faded away, the fever declined, and she is now once more convalescent. I also ordered her nostrils to be repeatedly syringed with warm water and vinegar. Here, gentlemen, you perceive our treatment has been successful in a case occurring under very unfavourable circumstances. It is a case, the study of which will afford you some instruction, parti- cularly if you compare its symptoms, progress, and treatment, with the case of erysipelas which occurred in the strong healthy girl who is lying near, and which we are at present treating on the emetico-carthartic plan. 48 graves’s clinical lectures.

LECTURE Y. The object of clinical instruction being the study of diseases— their nature and their treatment—it is our duty to apply that study in the manner most likely to encourage the accumulation of prac- tical knowledge. In accordance with this view, and in order to prepare you for the various emergencies that may hereafter demand the application of that knowledge, I shall proceed to select, from the cases at present in the house, such as, from their singularity, interest, or importance, seem to claim something more than a mere passing notice. A man named James Byrne, who lies next the door in the chro- nic ward, and has been supposed to labour under aneurism of the thoracic aorta, leaves the hospital to-day. It is very probable, how- ever, that he will hereafter be forced to return ; for, whatever be the nature of his disease, it is incurable, and depends on some profound organic lesion. I would advise any gentleman, who has not attended to this very obscure case before, to take the opportunity of making an accurate examination of the patient during the short time he remains in the hospital. While the phenomena of this case are still fresh in our minds, let us briefly discuss the question, whether this man really has aneurism of the thoracic aorta, and enquire whether there may not be some other cause to which his symptoms might be attributed with a more reasonable degree of probability. He was admitted on tlTe 23d of October, 1834, and had been in the hospital before for a considerable time. He states that, eighteen months previously to his last admission, he was exposed to wet and cold, which pro- duced a feverish attack, with symptoms of local inflammation in the lung, manifested by cough and difficulty of breathing. These were soon afterwards followed by dropsical swelling, and he applied at this hospital for relief. After remaining under treatment for about two months he began to improve, and left the hospital, as he states, quite relieved. He enjoyed tolerably good health, and con- tinued to work at his trade as a bricklayer until about five weeks before his last admission, when he was again attacked with cough and difficulty of breathing, accompanied by oedema of the left side of the chest and left arm. On examining him after his admission, the following phenomena were observed:—The left side of the face and neck was slightly oedematous; the left external jugular vein, with its immediate branches, engorged and very prominent; the THORACIC ANEURISM. 49 left arm and left side of the chest cedematous, and pitting on pres- sure ; no affection of the bronchial mucous membrane, or paren- chyma of the lungs, sufficient to account for the cough, can be detected by auscultation. Considerable dulness over the situation of the heart, and extending upwards over the sternal region on the left side ; the right sternal region sounds clear and natural. The heart has not been removed from its normal situation ; its pulsa- tions can be felt over the ordinary extent, and no more, and they communicate a natural impulse to the finger. On applying the stethoscope over the heart its sounds were found to be regular and natural, but on placing it higher up, over that part of the sternal region which was dull on percussion, a loud bruit de rape was heard. Let us analyse these symptoms. In the first place, we found the anasarcous swelling occupying the left side of the chest and the corresponding arm, and in a slight degree the left side of the neck and face, accompanied by a turgid state of the jugular vein. Now, you may lay it down as a general rule, that where one side of the chest and the corresponding upper extremity is affected by ana- sarca, it proceeds from some cause residing in the chest. I have told you before that in all cases of dropsy, whether acute or chro- nic—whether accompanied by ascites or not—when anasarcous swelling appears in the trunk and upper extremities before it is observed in the abdomen or lower extremities, the dropsy in gene- ral is inflammatory, or, when not so and chronic, it proceeds from disease of some of the thoracic viscera, and it is in the chest alone that we are to look for its cause and origin. Now, applying this rule to the present case, we are led to enquire what is it that, by pressing on the veins within the chest, gives rise to engorgement of the superficial vessels on the left side of the neck, and to ana- sarcous swelling of the left arm and left side of the chest. The pressure must, in our patient, be applied to a portion of the venous system, which carries blood from the left side of the head and the left upper extremity ; in short, it must be applied to the great vein formed by the junction of the left subclavian and left jugulars. Now, this left vena innominata sive vena brachio- cephalic a differs considerably from its fellow on the right side, which is very short, and nearly vertical in direction. The vein on the left side is three times longer, and directed transversely to the right, inclining at the same time downwards. It crosses behind the first bone of the sternum, lying in front of the three primary branches given off from the transverse portion of the arch of the aorta. You per- ceive, therefore, that it lies in a position most convenient to receive pressure in consequence of aneurism in any of these great vessels. This vein receives, before joining the cava, the internal mammary vein of the left side ; you understand, now, why any thing pressing on it is apt to produce engorgement of the superficial veins on the left side of the chest and trunk, together with oedema of these parts. That we are not to look for the cause of the disease in the heart itself, appears from various circumstances. The situation of that 50 graves’s clinical lectures. organ is not changed; its beating can be felt only over the usual extent of surface ; it communicates a natural impulse to the finger, and when examined with the stethoscope its sounds are discovered to be normal and regular. Neither can we attribute the disease to any affection of the mucous lining or parenchyma of the lung; the only morbid sounds which can be detected in the respiratory organs being a few slight bronchial rales. Now, it is sufficiently obvious that the situation of the part which sounds dull on percussion would suggest the idea of aneu- rismal dilatation of the arch of the aorta, or some of its immediate branches. But had dillness over so large a space of the chest, embracing nearly the whole left sternal region, been produced by aneurism of the aorta, or any of its branches, it is evident that the aneurismal sac must be very large. Where an aneurism gives rise to extensive dulness of the chest, you may be always certain that it has arrived at a very considerable size; for the dulness is caused by the immediate contiguity of the aneurismal sac to the parietes of' the chest, and hence the dulness is always in proportion to the amount of lung displaced. When you applied your hand over the sac, in such a case as that which we are now7 considering, where the aneurism was of large size and closely applied to the parietes of the thorax, you would feel a very remarkable pulsation ; your hand would be, as it were, lifted from the chest by each impulse communicated to the sac, and you would have palpable, unequivo- cal evidence of the cause of the dulness on percussion. Now, in the case before us, there was no such pulsation observed—whether we examined him while lying quietly in bed, or after he had walked briskly about for some time so as to excite the action of the heart and arterial system. Again, aneurismal sacs, as you are all aware of, before they produce extensive dulness of any portion of the parietes of the chest, point, as it were, in some particular situa- tion, becoming distinctly prominent, and producing an eccentric motion around them, in consequence of the thoracic parietes being absorbed, or yielding at the point of greatest pressure. From these circumstances, considerable doubts have arisen in my mind as to the cause of this man’s symptoms being connected with aneurismal disease of the great vessels of the thorax. I am rather inclined to attribute the bruit de rape, and dulness of sound on percussion, to a lesion of a different character. Let us suppose that in this case a tumour has been developed in the cellular or glandular substances, situated in or towards the left side of the chest, occupying the anterior mediastinum, pushing back the lung, and pressing on the large vessels connected with the base of the heart; what are the phenomena it would naturally present? First, we should have dulness of sound on percussion, corresponding in extent with that portion of the chest to which the tumour was applied ; secondly, we should have bruit de sovfflet, and probably bruit de rape, in consequence of the pressure of the tumour on the aorta; thirdly, a tumour in this situation would necessarily com- press some of the larger bronchial tubes, and thus give rise to THORACIC ANEURISM. 51 cough and dyspnoea. If a tumour presses on the trachea, or one of the larger bronchial tubes, why does it produce pulmonary irri- tation? Not by mere pressure on the part—for the pressure is applied so gradually, and with such a broad surface, that its effects could be scarcely felt; and it might go on to produce complete obliteration of the tube without giving rise to any inflammation, if its action were limited exclusively to the part compressed. But it strangles, as it were, that portion of lung to which the tube be- longs ; a certain portion of a large bronchial tube is considerably narrowed by the pressure of the tumour, the free entrance and exit of air are impeded, and consequently that portion of the lung, which may be very large, is greatly deranged in its functions. Hence arises that sensation of distress termed dyspnoea. Again, as soon as the free ingress and egress of air are prevented, we have not only the occurrence of dyspnoea, but also other effects equally referable to the same cause; the blood circulating through that part of the pulmonary tissue is imperfectly aerated, and does not undergo the necessary change; the secretions and exhalations from that part are altered and unnatural, and consequently it becomes engorged, giving rise to irritation, cough, and expectoration. To understand this aright, you should bear in mind that this portion of the lung undergoes the same changes that the whole of the lung undergoes in persons who are asphyxiated; that is, it becomes gorged with blood—for the moment that the black venous blood, which is carried into the pulmonary tissue from the right side of the heart, ceases to be properly aerated, that moment it stagnates in the lung, and soon renders it engorged. This is precisely the state of lungs which occurs in the posterior portions of those organs in persons who die a lingering death, and which has most absurdly been termed the pneumonia of the dying. But, to return to this man’s case, I am inclined to think that the symptoms here present may with more colour of probability be attributed to the presence of a solid tumour developed in the chest, the nature of which I can only guess at, and that it is situated in the anterior mediastinum, close to the origin of the aorta. Some of these tumours which have been discovered in the chest are of an adipose nature; some of them resemble the cerebral substance in colour and consistence, and others are like the steatomatous tumours formed in other parts of the body. A few months ago, Surgeon Blackley was consulted about a young gentleman who had been gradually attacked with symptoms of pulmonary irritation, cough, and difficulty of breathing. The disease was supposed by some to be consumption, and a physician who had been in attendance thought it depended chiefly on de- rangement of the stomach. Mr. Blackley had his doubts with respect to both of these opinions, and requested of me to visit and examine the patient. I could not detect any rales indicating the existence of tubercles, but over a large portion of the chest, and nearly corresponding with that part which sounds morbidly in the patient Byrne, there was dulness on percussion, the young gentle- 52 GRAVEs’s CLINICAL LECTURES. man had fits of cough and dyspnoea, and now and then difficulty of swallowing ; a bruit de soufflet could be heard over the dull por- tion of the chest, but the sounds and impulse of the heart were regular and natural. I expressed a very doubtful opinion of the case, but at the same time stated my belief that the case was not one of tubercular phthisis, of empyema, or of pneumonia ; and I also said that it did not seem to be produced by disease of the heart itself. I dwelt especially on the existence of bruit de soufflet in the region which was dull on percussion, and which was some- what removed from the heart, and which, from its situation, I inter- preted as indicating something pressing either the arch of the aorta, or some of its branches. I was not able to detect pulsation or any other symptom of aneurism, and consequently professed myself unable to say what that something was. The result proved that, although the true cause of the disease did not occur to me, I had nevertheless approached the discovery as nearly as could be done without actually making it; for, soon after this, the young gentle- man died, and on opening the chest a large tumour of a steatoma- tous character was discovered pressing on the divisions of the trachea, of the aorta, and on the oesophagus. Another case of the same kind was published some time ago in the Dublin Medical Journal. We are, I believe, still in the infancy of diagnosis, so far as regards tumours developed in the chest, producing anoma- lous symptoms, and giving rise to suspicions of aneurismal or tubercular disease. With respect to the patient Byrne, I am in- clined to think that the morbid phenomena are referable to a tumour of this description, and I ground my diagnosis chiefly on the absence of pulsation, which should be distinctly present if the dul- ness on percussion, here observable, depended on the proximity of an aneurismal sac to the parietes of the thorax. As I am speaking of pulsation, permit me to observe that, in some cases, where there is no actual disease present, the pulsations of the heart are visible over a very large extent of surface, so as to convey the impression that aneurismal dilatation exists. Of this I have lately seen a very remarkable example. In a case which I saw this week with Mr. Cusack, the patient’s heart could be ob- served beating violently over the whole chest, and Mr. Cusack, when he laid his hand on the patient’s chest, said he could not divest himself of the idea that there was some unnatural condition of the heart and great vessels. Now the violence of the heart’s action in this case depended on disease of the brain. In some inflammatory or congestive diseases of the brain with a tendency to coma the heart labours intensely, its pulsations are quite awful, and it seems as if it were about to burst through the parietes of the chest. Again, this extraordinary action of the heart occurring in cerebral disease is almost invariably accompanied by a hard bound- ing pulse. I mention these circumstances for the purpose of putting you on your guard, and that you should not in such cases allow yourselves to be deceived, and suppose that the symptoms are to be met in every instance by copious blood-letting. Some cases of this THORACIC ANEURISM. 53 description will bear depletion well, others will not. Yon know it was a maxim of Laennec’s, that in bleeding we are to be guided more by the strength of the heart’s action than by that of the pulse. I have already shown that this test does not always hold good. You recollect the patient who was under treatment here some time ago, with violent action of the heart and a hard bounding pulse. This patient, a strong healthy man, had just disembarked, after a rough passage from Liverpool, during which he vomited much, and suffered intensely from headache, which he ascribed to the violence of retching. Walking along the quay, he was suddenly attacked with hemiplegia, and was immediately brought into the hospital, where he was bled and purged. Next day we found him still hemiplegic, and complaining of violent pain in the head. Active antiphlogistic treatment was used, but on the third day he became comatose, and was convulsed in the limbs of the healthy side. His face was flushed, his temporal arteries were dilated and pulsated violently, and his pulse was hard, while the heart pulsated with great strength. This attack came on during our visit, and I ordered a vein to be opened immediately. The blood flowed freely. When about fourteen ounces were taken the pulse suddenly flagged and grew extremely weak, and never again rose. He died in about two hours, and an ignorant person would have ascribed his death to the bleeding. On examination, sixteen hours after death, we found extensive puriform effusion on the surface of the brain, to- gether with a large clot of blood and surrounding ramollissement. This was a very remarkable case, and conveyed a very important lesson, teaching us not to be too much led away by the violence of the heart’s action ; for I have no doubt that here the use of the lancet shortened the man’s life. Had such a case as this occurred to any of you in private practice, it would be almost fatal to your reputation. Here we have a patient with his face flushed, his skin hot, his temporal arteries throbbing violently, and his pulse feeling like a piece of whip-cord ; he is blooded, and up to a certain point the pulse remains firm; he then begins to sink rapidly, and expires in two or three hours. Bear in mind, then, that a state of the sys- tem may exist, in which the heart’s action is intense, and the pulse hard and bounding, and yet where bleeding to any amount will be badly borne. Such cases are generally connected with inflamma- tion of the brain, accompanied by a tendency to coma. Here you must bleed with great caution, let the quantity you take away be moderate, and rather rely upon large relays of leeches and strong purgatives for removing the cerebral symptoms. You may after- wards endeavour to moderate the heart’s action by the use of digi- talis and opium ; a grain of the former, and one twelfth of a grain of the latter, made into a pill with some extract of hops, may be given every second hour, until it begins to produce some effect on the heart’s action, when it may be either discontinued or given at longer intervals, as the circumstances of the case may require. Where, after bleeding and other antiphlogistic measures, the pulse continues high, and the action of the heart violent, I can recom- 54 graves’s clinical lectures. mend digitalis very strongly, and the small portion of opium here combined with it can do no harm. Combined in small quantities with digitalis, opium does not produce any tendency to determina- tion to the head, and it prevents the digitalis from sickening the stomach. I have frequently employed it, and found great benefit from its exhibition. I may observe, that when you are anxious to secure the full sedative effects of digitalis on the heart and pulse, you must give it in large doses. In small quantities it does not act well, and seems rather to produce a tendency to excitement of the heart. There is another patient about to leave the hospital to-day, on whose case I wish to make some observations. This young man, whom you have seen lying in the chronic ward, in the bed next but one to Byrne’s, caught cold about seven or eight months ago, followed by cough, wheezing, and dyspnoea, which, after a month or six weeks, subsided. About two months before he came into the hospital, he renewed his cold, and with it the cough and dys- pnoea returned. On his admission he complained of difficulty of breathing, which attacked him every night; he went to bed well, and slept tranquilly for two or three hours, and then was awakened by pain and sense of tightness in the chest, with great dyspnoea. When the paroxysm came on, it compelled him to get up and walk about the room gasping for breath; and, after continuing for two or three hours with great dyspnoea, wheezing, anxiety, and cough, went off with free expectoration and sweating. As soon as the sweating and expectoration appeared, he lay down without any inconvenience, and slept quietly until morning. The only addi- tional symptom he complained of was palpitation of the heart, which sometimes affected him when employed at hard labour. On examining the lungs there was nothing found except a few bron- chitic rales. The heart was normal in its action, and no morbid sound could be detected by the stethoscope. In addition to this, you will recollect that the man was in the prime of life, had a full and well-formed chest, a quiet pulse, regular bowels, and a good appetite. Here you perceive a man from repeated colds gets chronic irri- tation of the bronchial tubes, and this induces asthmatic paroxysms, which come on, as is usual in such cases, at a certain hour of the night. It was plain, therefore, that he was labouring under a well marked form of asthma, a disease which, in its pure and simple state, is seldom met with in hospitals, being generally observed in connection with disease of the heart, or long-continued bronchitis in old persons. Chronic bronchitis is one of the most common causes of asthma; indeed, you will scarcely ever meet a patient who has been subject to chronic irritation of the bronchial tubes, who does not also labour under more or less asthmatic dyspncea. The disease is generally met with in persons advanced in life, and who have suffered from repeated attacks of bronchitis ; it is not usual to find it in so young a man as this patient, and presenting, as he does, such very slight symptoms of derangement of the bron- chial mucous membrane. ST. JOHN LONG’S LINIMENT. 55 This case exhibits a remarkable proof of what may be done by simple means in relieving an urgent disease. The man was, with the exception of asthma, in good health ; his bowels were regular, his appetite good, his pulse tranquil, and the signs of pulmonary irritation trifling. There was no necessity, then, for administering remedies to improve the tone of the digestive organs, nor were we authorised to use the lancet or apply leeches. I therefore confined my attention to two points : the application of irritants to the neck and chest externally, and the internal use of remedies calculated to relieve bronchial irritation. I ordered him to rub the nape and sides of the neck, and the fore part of the chest, with a liniment composed of strong acetic acid, 3ss, spirit of turpentine, 3iij, rose water, 3 iiss, essential oil of lemons a few drops, and yolk of egg in sufficient quantity to suspend the turpentine. This liniment is an imitation of the celebrated liniment of St. John Long. I gave a bottle of the real liniment to Dr. Apjohn, to analyse, and he thinks it consists of acetic acid, spirit of turpentine, and two animal mat- ters, one containing azote, the other not; the latter probably some species of fat, probably goose-grease. Now this fat did not exist in St. John Long’s liniment in the form of soap, it was evidently some kind of fatty matter blended with water, probably by means of trituration with yolk of egg. The active ingredients are spirits of turpentine and strong acetic acid. This liniment should be applied by means of a sponge. It acts as a rubefacient, and generally in- duces an eruption of small pimples after a few applications. The spirit of turpentine must be well mixed with the water (which ought to be added to it gradually) by means of yolk of egg, before the acetic acid is added. With this liniment our patient was desired to rub the fore part of the chest, and the nape and sides of the neck. It was applied to the chest with the view of relieving the bronchial irritation, and we ordered it to be rubbed over the nape of the neck, along the course of the cervical portion of the spinal marrow, and over the sides of the neck along the course of the pneumogastric nerve, because all the organs to which the latter nerve is distributed, are evidently affected in cases of spasmodic asthma. Thus a paroxysm of asthma is not only attended with increased action of the heart, dyspnoea, and hurried breathing, but also with marked derangement of the stomach, particularly towards the termination of the fit, when the patient generally has a feeling of uneasiness in the sto- mach, with flatulence and a sense of ’fulness, induced probably by the derangement of circulation in the lung. You are aware of the close sympathy which exists between the stomach and lungs, and you must have been struck with the fact, that stimulant and irritating remedies applied to the epigastrium often relieve affections of the lung more completely than when applied to the chest. Thus in using the tartar emetic ointment for the relief of hooping-cough, it has been found to act most beneficially when applied over the region of the stomach ; and the same thing may be said of Roche’s embrocation, which does more good when rubbed over the spine 56 graves’s clinical lectures. or epigastrium, than when applied to the parietes of the thorax. On these principles, I ordered the counter-irritation to be applied over the course of the cervico-spinal and pneumogastric nerves, over the chest, and subsecpiently over the stomach. This liniment in a very short time produces redness and heat of the parts to which it is applied, and it is more than probable that its effects are not limited to temporary rubefacience, but that it also acts on the nervous system. We have innumerable proofs that turpentine exercises a special influence over the nervous system, and we know that it is rapidly absorbed even without the aid of friction. I fear, however, that we shall never be able to confer on our liniment all the wonderful properties attributed to that of St. John Long. You know it has been asserted that St. John Long’s liniment never reddened the skin, except over the exact spot where disease was situated. 1 was assured by a young lady who used this liniment, that she rubbed it all over the chest, and that it pro- duced no discoloration of skin, except in two spots where she felt pain. She at first mentioned but one spot which was painful, but St. John Long, having applied the liniment himself, told her she had deceived him, and that there was pain in another spot. It had other effects equally miraculous. An eminent Dublin lawyer de- clared that it drew nearly a pint of water from his head, and Lord Ingestre testified that it extracted quicksilver from his brain ! These, and other wonderful stories, told by several persons of dis- tinction with a full belief in their authenticity, furnish a useful lesson to mankind, showing that gross credulity is not confined exclusively to the poor and the ignorant, but may be found among the highest classes of society. It is a singular fact also, and illus- trative of the tendency which exists in human nature to deceive and be deceived, that notwithstanding the repeated failure, and even fatal effects, of St. John Long’s applications, many persons still regard his opinion as oracular, and look upon his remedies as ines- timable discoveries. When I mentioned to the gentleman who brought me the bottle of liniment, that St. John Long himself died of phthisis, and brought this forward as a strong argument against the infallible efficacy of his remedies, he said that this very circum- stance was one of the most remarkable proofs of his sagacity, for St. John Long had always maintained that the liniment was not suited to his own case, and that there was something in his consti- tution which neutralised its good effects; and so it happened, for when he applied the liniment to his skin it did not produce the red spots which usually resulted from its application in other persons. In fact, such was the credulity of St. John Long’s patients, that his death passed among them as the strongest proof of the infallibility of his medicines. Indeed he is considered by many of our nobility as a sort of medical martyr, who, having sacrificed life in the accomplishment of his mission, rising from earth, let his prophetic mantle fall on the highest bidder ! But to return to our patient. In this case the liniment did a great deal of good, but it was not the only means we employed. CHRONIC BRONCHITIS. 57 We observed that the asthmatic paroxysm came on every night, continued for two or three hours, and then went off with free ex- pectoration and sweating. In order to prevent this, we gave him a draught, which he was to take when awakened by the pain and sense of tightness in his chest. He took this, and it had the effect of arresting the paroxysms, so that he no longer found it necessary to leave his bed. That this remedy had succeeded in averting the disease, was plain from the following circumstance:—one day the clinical clerk had omitted to repeat his draught, and he consequently got no medicine; on that night the asthmatic paroxysm returned and went through its usual course as before. This draught was very simple, being composed of half a dram of tincture of hyos- cyamus, half a dram of vinegar of squills, and the same quan- tity of ipecacuanha wine in an ounce of camphor mixture. It is scarcely necessary for me to explain the nature of the ingredients. The tincture of hyoscyamus possesses narcotic and antispasmodic properties, and ipecacuanha and squill are known to have great efficacy in disease of the bronchial mucous membrane, being both promoters of expectoration, and the latter also acting on the urinary organs. Without, however, attempting to explain the precise mode in which each of these ingredients acted, it will be sufficient to state that the combination had a beneficial effect, and checked the asthmatic paroxysms. We persevered in using it, as well as the liniment, until all tendency to asthma had disappeared, and the normal state of the function of respiration became perfectly re- established. There is in the male chronic ward a patient named Garret Kane, to whose case I shall for a few moments draw your attention. This man is about forty-five, and, like most of his countrymen who have been addicted to whiskey, he is beginning to show the fatal effects of intemperance. He had been ill for several months before he came into the hospital, and is at present labouring under general anasarca, affecting the chest, upper and lower extremities, accom- panied by an accumulation of fluid, but not very extensive, in the cavity of the peritoneum. I do not intend here to enter into the general pathology of dropsy, or to enquire what was its origin in this instance ; I shall confine myself to an explanation of the rea- sons which have induced me to select the plan of treatment I have adopted. In the first place, it is a case of chronic dropsy ; secondly, it is unattended by fever; thirdly, it is a case in which mercury has been used with some temporary relief, but the disease returned afterwards in a worse form; lastly, it is dropsy accompanied by obstinate diarrhoea, and therefore contra-indicating the use of pur- gatives or even of diuretics, for you are aware that the whole class of diuretic medicines acts more or less on the intestinal canal. I may mention here, acetate and nitrate of potash, turpentine, colchi- cum, squill, and many other remedies of the same kind. All diuretics act either as purgatives, or they have a stimulant and irri- tating effect on the bowels. This patient has bowel complaint, and therefore we are prevented from giving diuretics or purgatives ; 58 graves’s clinical lectures. and the absence of inflammatory symptoms precludes the employ- ment of the lancet or cupping-glasses. You perceive that our field for practice is extremely limited ; we dare not bleed, cup, purge, give mercury, or diuretics ; the nature of the case contra-indicates the use of all these remedies, and hence we are deprived of the power of using the most energetic agents employed in the treat- ment of dropsy. What then is to be done ? Having observed that the man’s appetite and thirst are very great, and that his urine con- tains a large quantity of albumen, that he has no fever, and no symptoms of local inflammation, 1 decided at once on trying the efficacy of Dover’s powder in doses of a scruple in the day, divided into four pills, and gradually increased until it amounts to half a dram, or two scruples, in the twenty-four hours. A species of analogy exists between cases of this kind and cases of diabetes; in both there is the same tendency in the blood to part with its watery constituents, in both the same inordinate thirst and craving appetite are observed, and in both there is the same deposition of animal matter in the urine. The principal difference between them is, that in one case the watery fluid is effused into the cellular sub- stance and peritoneal cavity, while in the other it is eliminated from the system through the medium of the kidneys. It was this analogy which led me to adopt Dover’s powder in the treatment of this man’s case. Last year we had a patient here under treatment who was dropsical, and at the same time passed five quarts of urine daily ; before I had recourse to the ordinary treatment for dropsy, I determined to try the use of Dover’s powder. The disease yielded rapidly to this plan of treatment, and the man left the hospital quite relieved. In the patient Kane a small sore has formed on one of the lower extremities, perforating the skin and cellular substance to the depth of two or three lines; through this aperture a great deal of the anasarcous fluid has drained, and still continues to flow oft’. This is a very fortunate circumstance, as it will tend to prevent any ex- cessive accumulation in the cellular membrane. Previous to its occurrence I had ordered the scrotum and prepuce, which were enormously distended, to be punctured with a needle. The best mode of doing this is to prick the part quickly, so as to give as little pain as possible, the point of the needle should merely pene- trate the true skin, the punctures should vary in number from twenty to fifty or sixty, according to the size of the part and the extent of the effusion, and they should be at least half an inch asunder. By observing these rules you will succeed in evacuating the water without running the risk of exciting erysipelas, which in such cases frequently leads to disastrous consequences. Punc- turing with a lancet is not so good as with a needle, it is much more apt to excite irritation in the parts, and thus lead to the super- vention of erysipelatous inflammation. The judicious application of acupuncturation, in cases of chronic dropsy, often accomplishes a great deal, for when the external anasarcous oedema is thus drained away, the fluid in the peritoneal cavity is more rapidly SECONDARY SYPHILIS. 59 absorbed; in some cases, indeed, the good effects of external drain- age on the ascites are so rapid, that we are almost tempted to believe that some direct communication may exist between the subcutaneous tissue and the apparently shut sac of the peritoneum. Be this as it may, the good effects in some cases are as decisive as if such a communication existed. This phenomenon countenances the hypothesis of the possibility of fluids percolating through lining membranes. Note.—In the foregoing lecture I have adverted to a subject not hitherto sufficiently considered by pathologists, viz., the immediate effects produced in the bronchial tubes and pulmonary tissue when an internal tumour presses on one of the bronchi. The result is a certain degree of cough, expectoration, and dyspnoea. In some cases the bronchial inflammation thus produced may go on to actual ulceration, which authors have been too much disposed to regard as being mechanically produced by the local irritation of pressure. Professor Albers, of Bonn, cites one case in which a scirrhous tumour of the oesophagus produced ulceration of the neighbouring compressed bronchus, but he says nothing of the manner in which this effect was accomplished. In some cases, no doubt, inflammation may be propagated from the morbid growth, but in the tumours I speak of, no evidence of inflammation existed. Professor Albers’s observations on this subject may be seen in his paper on Widening of the Pulmonary Artery, Rust’s Magazin fur die gesammte Heilkunde, 42 Band, 1 Heft, p. 177.

LECTURE YI. You have observed that we have two cases of syphilis under treatment—one in the female, the other in the male chronic ward. They possess no peculiar interest beyond the ordinary run of syphi- litic affections, still they deserve a share of your attention ; for it is on your experience of individual cases, much more than on the knowledge derived from books, that your treatment of this obscure and Protean malady will depend. It is now more than a year since the female patient received the syphilitic poison into her constitution. What the nature of the primary sore was we cannot ascertain, but, from the account she has given, it seems to have been true chancre. Some time effer 60 graves’s clinical lectures. this occurred, she got sore throat, articular pains, and an eruption, for which she was treated in this hospital about ten months since, and dismissed apparently cured. The disease, however, returned in a few weeks, and she has been labouring under its effects up to the present moment. Three circumstances in this case demand our attention: first, the re-appearance of syphilis after a mercurial course—for she was mercurialised here soon after her first admis- sion ; secondly, she exhibits a degree of syphilitic cachexy, being rather pale and emaciated; and, thirdly, the slow progress which the disease has made in her system, being limited to a few blotches on the skin, some periostitic swelling of the bones of the leg, pains, and slight arthritis. In treating this case I intend to give mercury, so as to affect her system; and, having accomplished this, I shall keep her under its influence for some time. I shall also, should it appear necessary, order her a free allowance of the decoction of sarsaparilla. Under this treatment you will find that the eruption will soon disappear, the periostitic pains and swelling be removed, and the constitution begin to improve. She has been ordered three grains of blue pill, and half a grain of calomel, three times a day—a quantity which you will generally find sufficient to bring on mercurial action in females. I have no doubt but that the disease will, in this case, yield to mercury in a very short time, and. that her health will be completely restored. The failure of mercury in producing a per- manent cure, on a former occasion, is no argument against its employment here; if there were no syphilitic taint in question, I do not know any remedy by which the cutaneous affection and the periostitis could be more effectually relieved. On another occasion I shall speak more at large upon this important subject, and shall bring forward facts in proof of the assertion, that mercury may fail to eradicate the effects of the venereal poison at a certain period of the disease, and may nevertheless be capable of curing the dis- ease effectually at a future time. This may appear paradoxical, but it is not the less true. The other patient, John Kelly, presents an eruption of red scaly blotches, extensively diffused over the trunk and extremities, and closely resembling psoriasis. This man, like many others, denies the occurrence of a recent syphilitic taint, and gravely states that it is some years since he exposed himself to infection. Instances of this kind are to be met with every day; patients will not tell the truth about these matters, and false statements tend to throw a darker shadow over a disease in itself sufficiently obscure. How- ever, in this case, the poison seems to have confined its effects to the cutaneous surface; there is no affection of the throat, perios- teum, or joints. The eruption covers almost every portion of his body; it made its appearance two months before admission, and was preceded by feverish symptoms and pains in the larger articu- lations. In undertaking the treatment of this case, there is one practical point to be held in view. The man’s general health is good, his 61 SYPHILITIC ERUPTION. strength undiminished, and his circulation active. I therefore ordered him to be blooded, and have kept him for eight or nine days on antimonials and low diet. By preparing him in this way, I knew that the mercury which I intended to give him would act more rapidly on his system; and such was the case—for on the second day after he commenced using it his mouth became affected. But here a difficulty arose, which, in cases of this description, is apt to embarrass our treatment: the mercurial influence appeared much sooner than I expected or wished. He had been ordered three grains of blue pill, and half a grain of calomel three times a day ; and on the second day, before he had taken six pills, saliva- tion commenced. Now, in all cases where mercury affects the mouth sooner than you desire, and as it were in spite of you, it will not do as much good as where its action proceeds regularly and in accordance with your purpose. It is a general rule, that most benefit is to be expected from mercury where its action is regularly progressive, or where the quantity taken is in proportion to the effect produced on the system. Hence we look upon it as an unfavourable occurrence, when a small quantity of mercury occa- sions sudden and copious salivation ; such an event deranges our calculations, and tends to embarrass our practice. Now, in this case the patient, after taking five pills, became salivated on the second day. We found we had been going on too fast; it was necessary therefore to pause, but not desist. We accordingly re- duced the quantity of mercury to three grains of blue pill, and half a grain of calomel, to be taken every second night. By these means we kept up a slight discharge of saliva, and the man’s symptoms began to improve. The eruption is now disappearing rapidly, and it is to this point I wish to call your attention. What are the marks which indicate the subsidence of an eruption of this kind, and by what criterion are you enabled to judge of the progress of the cure ? When the parts are about to return to their healthy condition, three circumstances occur; first, the vivid red or copper colour of the eruption begins to fade; secondly, the heat of the affected parts becomes reduced; thirdly, the excessive secretion of morbid cuticle is arrested, and the quantity of minute scales cover ing the blotches diminished. In such cases, the affected parts of the skin are highly vascular, and the secretion of cuticle is mor- bidly excessive in quantity; hence the continued desquamation from the surface of the blotches. You should, therefore, attend not merely to the colour of the eruption, but also to the quantity of minute scales on each blotch, when you wish to ascertain whether an eruption is fading or not. You can judge of this by your eye, or you can tell it by passing your finger over the diseased surfaces. The fading of the colour of the eruption, the decrease of the eleva- tion and roughness in the blotches, and the gradual disappearance of the minute scales—these are the circumstances by which you can ascertain the subsidence of a syphilitic eruption. As the cure progresses, you find the parts assuming a more natural appearance; the same quantity of morbid cuticle is no longer thrown out by the 62 graves’s clinical lectures. affected spots of corium; the blotches become smooth and lose their elevation, and, finally, the red colour of the skin disappears. Of all the symptoms, discoloration of skin is the last to recede, and it generally happens that enough has been done in the way of treat- ment long before the skin resumes its natural complexion. If you were to continue the administration of mercury until the natural colour returned, you would very often push it to a useless and even dangerous extent. In such cases, a faded brownish or dirty tinge remains long after the re-establishment of healthy action. There is a case in the female fever ward which requires a pass- ing observation. A young woman, previously in the enjoyment of good health, was seized with symptoms of fever after exposure to cold ; she got rigors, followed by headache, hot skin, thirst, nausea, and acceleration of pulse. It is unnecessary for me to detail the symptoms which attended her illness during the past week; I shall content myself with pointing out the symptoms which particularly attracted my attention to her case on Saturday morning. At that time her fever had increased; she complained of severe headache and restlessness; had foul tongue, thirst, and symptoms of gastro- intestinal irritation. Such matters, however, demand no very par- ticular consideration; what chiefly fixed my attention was the occurrence of slight and transient rigors during my examination : I observed her shuddering three or four times in the space of a few minutes. On questioning her respecting these brief rigors, she in- formed me that they had occurred with more or less frequency for the last three days. Now. wdienever you meet with a symptom of this description in fever, be on your guard; watch the case with anxious, unremitting attention, and never omit making a careful examination. It is in this way that one of the worst complications of fever—treacherous and fatal disease of the brain—very often commences. On examining this girl, we found that she had not only headache, but also acute pain referred to the left ear, the exter- nal meatus of which was observed to be hot and tender to the touch. In addition to this, we were informed by the nurse that she had been seized with a sudden fit of vomiting shortly after we left the ward on the day before. Here was an array of threatening symp- toms calculated to awaken attention in any, even the most heedless observer. A patient, after exposure to cold, is attacked with symp- toms of fever ; she has headache and restlessness : she then begins to complain of acute pain in the ear, darting inwardly towards the brain ; and, finally, is seized with sudden vomiting. Under these circumstances, it is not difficult to form a diagnosis, and there can be little doubt but that the phenomena here present were indicative of incipient inflammation of the membranes of the brain. It is not easy to say whether in such cases the inflammatory affection of the membranes precedes the external otitis, or whether the inflamma- tion commences in the external ear and spreads inwards, though I am inclined to adopt the latter supposition, and the circumstance of the fever and earache arising from cold seems to give an addi- tional degree of probability to this view of the question. Be this INFLAMMATION OF THE BRAIN. 63 tis it may, there could be no doubt but that this girl was, on Satur- day, labouring under incipient inflammation of the membranes of the brain, as denoted by headache, rigors, acute pain in the ear, and vomiting. Here let me observe, gentlemen, that, in cases of this description, I look on the occurrence of external tenderness, not merely as an indication of internal disease, but also as a favourable symptom. I have remarked that in all cases where this happens, the physician becomes more speedily and sensibly aware of the existence of inter- nal disease, and the remedial means employed act with a more de- cidedly beneficial effect. I would prefer having to deal with an inflammatory affection of the brain or bowels, accompanied by external tenderness, and would feel much more certain as to the result, than if this symptom were but faintly marked, or totally absent. This observation is founded on experience. In treating this case, you have seen that I have ordered relays of leeches to be applied in the vicinity of the affected ear until the earache has ceased. I have long followed this practice of applying a number of leeches in succession for the relief of local inflamma- tion, and I can state with confidence that the result has been, in the majority of cases, highly satisfactory. Some prefer the application of a great many leeches at once; but my experience speaks strongly in favour of the practice of applying a small number, repeated at short intervals, until the violence of the local inflammation is sub- dued. Relays of six or eight leeches will suffice in the majority of cases of pectoral, cerebral, or abdominal inflammation. In some, however, when the attack is violent, fifteen or twenty must be applied at once; each succeeding relay may consist of a smaller number than that which preceded it. In this manner I have main- tained a constant oozing of blood from the integuments over an inflamed organ for twenty-four, or even thirty-six hours. In addi- tion to this, I determined to bring her system rapidly under the in- fluence of mercury, and, with this intent, administered calomel to the amount of a scruple in the twenty-four hours. These means have acted favourably, and she feels much better to-day. (This patient perfectly recovered.) Allow me to make one observation more which this case suggests. This young woman, you recollect, had, on her admission, some epigastric tenderness, which we removed by leeching, and she remained free from any symptoms of gastric irritation until last Saturday, when she got a sudden attack of vomiting. Now, in all feverish complaints, where, during the course of the disease, the stomach becomes irritable ivithout any obvious cause, and where vomiting occurs ivithout any epigastric tenderness, you may expect congestion, or incipient inflammation, of the brain or its membranes. If called to a case of scarlatina, where there is severe vomiting, and perhaps diarrhoea, unaccompanied by thirst or epigastric tenderness, what should your practice be? Are yon to direct your attention to the alimentary canal, and endeavour to arrest these symptoms? No. The vomiting here depends on 64 GRAVEs’s CLINICAL LECTURES. active congestion of the head, and such cases are very apt to end in coma, convulsions, or death, from disease of the brain. You are all aware, that in cases of injuries of the head, followed by congestion of the brain, vomiting is one of the most prominent symptoms. The same thing occurs in febrile affections, attended with determination to the head. You are not to conclude that a fever is gastric, because it commences with nausea and vomiting; this is a serious, and very often a fatal, mistake; yet I am sorry to say it has been committed by many practitioners, and I have been guilty of it myself. In such cases, you should not waste time in attempting to relieve gastric irritation by cold drinks, and leeches to the epigastrium, or to check diarrhoea by chalk mixture and opiates; you should direct your attention at once to the seat and origin of the mischief, and employ prompt and effectual means to relieve the cerebral congestion. Where the disease sets in with severe vomiting, unaccompanied by distinct evidences of gastric inflammation, whether it be common fever, or scarlatina, or measles, or small-pox, I commence the treatment by applying leeches to the head, convinced that in this way I shall be most likely to prevent an approaching dangerous congestion of the brain. I am anxious to impress this observation on your minds, because I am fully sensible of its importance, and feel certain that you will derive much advantage from bearing it in recollection during the course of your future practice. The next affection to which I shall draw your attention is chro- nic rheumatism, of which we have a well-marked instance in the man who lies in the chronic ward immediately under the window. He complains of pain, weakness, and numbness of the lower extre- mities, for which he used the decoction of sarsaparilla and minute doses of corrosive sublimate, for a fortnight, without any obvious improvement in his symptoms. His complaint is of considerable duration, it being now fifteen weeks since he was first attacked. This, I need not tell you, is a very unpromising feature in his case. When rheumatism has continued for three or four months, it be- comes a very intractable disease; indeed, there is scarcely any affection which tasks the ingenuity, and tries the patience, of a medical man more than chronic rheumatism. In this case, how- ever, we have been so fortunate as to hit on a remedy suited to the complaint; the man has been rapidly improving within the last fortnight, and is now nearly well. You will recollect that, when I undertook the treatment of this case, the patient was free from fever, his general health but little impaired, his pulse tranquil, his appetite good, no remarkable tenderness or redness of the joints— in fact, nothing to indicate the existence of acute local inflamma- tion ; consequently, it would have been useless to have recourse to leeches or blood-letting, or to administer antimonials, nitre, or col- chicum. In such cases as this a different line of practice must be followed; you must have recourse to stimulant diaphoretics—reme- dies which will increase the secretion from the skin, at the same time that they exercise a stimulating action on the nervous and CHRONIC RHEUMATISM. 65 capillary systems. Accordingly we prescribed for this man the fol- lowing electuary, of which he was to take a teaspoonful three times a dayPowdered bark 3j, powdered guaiacum 3j, cream of tartar 3j, flower of sulphur 3ss, powdered ginger 3j, to be made into an electuary with the common syrup used in hospitals. The guaiacum not only acts on the nerves, tending to remove chronic pains, but also acts on the skin: you will find these, and other pro- perties possessed by it, detailed at large in your works on Materia Medica. Whether given in the form of powder or tincture, it often proves an extremely useful remedy in cases of chronic rheumatism, where no symptoms of active local inflammation or general fever exist; where either of these are present it is inadmissible. Ginger has also a stimulant effect, although its action is much more limited. It is a favourite domestic remedy, and is very frequently prescribed by our rival candidates for therapeutic celebrity—old ladies—in cases of chronic, or, as they term it, cold rheumatism; and I must confess that I have seen some benefit derived from their specific— ginger tea. With these we combined sulphur, which exerts a pecu- liar stimulant operation on the skin and alimentary canal. Sulphur is an extremely active remedy, and singularly penetrating in its nature, finding its way into many of the secretions and most of the tissues of the body. You will find it in the urine in the form of sulphates, and it is exhaled from the skin and mucous membrane of the bowels in the form of sulphuretted hydrogen. Having said so much respecting sulphur, you will perhaps enquire why I pre- scribed the bark ? It is not easy to give a satisfactory explanation of this; but we know, from experience, that in cases of rheumatism, after fever and local inflammation are removed, bark and other tonics have been found extremely valuable. The cream of tartar is given with the view of tempering the other stimulant remedies, it being known to possess cooling and aperient properties. The whole form a combination which is similar in its composition to a well-known popular remedy for rheumatism—the Chelsea Pen- sioner. Having thus explained the general tendency of these medicines, and mentioned that they are to be made up into an electuary, it only remains to speak of the effect produced, and the dose or quan- tity to be given. I have stated that the ordinary dose is a teaspoon- ful three times a day; this, however, will be too much for some, and too little for others. The object in every case should be to keep up a mild but steady action on the bowels, and to procure a full alvine discharge at least once a day. If the dose mentioned already does not answer this purpose, it must be increased; if the bowels are too free, it must be diminished. You should never omit making regular enquiries after the state of the bowels, while the patient is using this electuary; for, if these matters are neglected, the patient will not obtain the full benefit to be derived from it. Besides opening the bowels, this electuary acts on the skin, and fre- quently causes a rapid disappearance of the disease. I need not say that, in addition to this, I ordered warm baths; they coincide 66 graves’s clinical lectures. in effect with the electuary, acting on the skin, and tending to relieve the rheumatic pains. There is another very remarkable case bearing some affinity to the preceding, on which it may be necessary to offer a few remarks; I allude to the patient with sweating arthritis, to whom I drew your attention this morning. This poor man. who is somewhat advanced in life, has been labouring for several months under inflammation of the joints of a rheumatic character, manifesting itself by pain, stiffness, swelling, and probably some slight effusion into the syno- vial membranes. These symptoms were accompanied by profuse and constant perspirations, with a tendency to diarrhoea—circum- stances which caused a manifest deterioration of his health and strength ; he became pale, cachectic, and emaciated. His case had been very tedious and intractable; he had been a long time in the hospital, and had used all the most appropriate remedies, but with- out any appreciable improvement; his joints remained stiff, painful, and almost useless; he was greatly reduced in strength, and entirely confined to his bed. In addition to this, his pulse continued unre- duced in frequency, and this is always a bad sign; cases of rheu- matic arthritis, attended by prolonged excitement of the circulation and copious sweating, are generally found to exhibit an intractable chronicity, and too often terminate in rendering the unfortunate patient a cripple for life. Now in this case many remedies had been tried without effect, and the state of the man’s constitution, combined with the circum- stance of his having a tendency to bowel complaint, contributed to reduce still further the scanty list of our remedial agents. Altera- tive remedies, to affect the general system, were almost entirely out of the question, and a vast number of local applications had proved unsuccessful. It occurred to me here, that some benefit might be derived from mercurial ointment, gently rubbed over the affected parts, assisting its action by the use of rollers applied round the joints. Fortunately, the experiment proved successful; in the course of a week or ten days, the swelling diminished considerably, the pain is nearly gone, and the power of motion is returning. His mouth has become affected, but the relief experienced appears to be proportioned, not to the influence of mercury on the general system, but to its effect on each individual joint. As a proof of this, I may state that the man has been mercurialised before, but without any favourable result. Here, gentlemen, is an important point for consideration. A patient labours under a certain number of local inflammations, for which mercury is given internally, so as to affect the mouth, but without any manifest improvement of symptoms; we afterwards try the same remedy in another form; we apply it locally, in the shape of ointment, rubbed into the skin over the diseased parts, and we succeed in giving relief. This is a fact deserving of attention. You will perhaps ask me to explain this—I cannot do it; but I can bring forward many other analogous examples. If you refer to Mr. M‘Dowel’s valuable paper on Erysipelas, published in a late number ARTHRITIS. 67 of the Dublin Medical and Chemical Journal, you will find that many cases of this affection derived great benefit from the use of mercurial ointment; in fact, much more than they could by giving mercury internally. In the next place, I have met with many cases of enteritis and peritonitis, where the disease continued after the system became affected by mercury; and I have observed that these cases yielded rapidly to blistering the abdomen, and dressing the raw surfaces with mercurial ointment. Dr. Marsh and I attended a young gentleman lately, who had low fever, accompa- nied by a quick but feeble pulse, and great restlessness. About the tenth day, his belly became tender and exquisitely painful; he had thirst, diarrhoea, and other symptoms of enteric and peritoneal inflammation. Before his illness, he had been of rather delicate habit, and had further impaired his health by close study. He was therefore unfit for depletion, and of this we were convinced by the debility which followed the application of a few leeches. Under these circumstances, we ordered a large blister to be applied to the abdomen, and the vesicated surface to be dressed with mer- curial ointment. This proved eminently successful; the perito- nitis, enteric irritation, and fever, soon disappeared, and the young gentleman recovered completely. The same thing is seen in many cases of pleuritis; the constitutional effect of mercury will fail in removing the affection of the pleura until it is applied locally. I might also refer to instances of common inflammation of the testicle, in which mercurial ointment, smeared over the part, has been found decidedly beneficial. It is unnecessary for me, how- ever, to multiply examples; what I have stated give ample proof of the utility of mercury applied locally. When I was a student, it was the fashion to scout the doctrine that any distinct effect could be produced by the local application of mercury; our teachers laid it down as an axiom, that, to produce any sensible effect, it was necessary that it should first enter the system through the lym- phatics. Thus, when you mb mercurial ointment over the liver to remove hepatic derangement, they said, before it could exert any influence on the liver, it had to pass along the thoracic duct, be- come mixed with the circulation, and manifest its peculiar action on the whole economy. Hence, in a case of hepatitis or testitis, it was deemed useless to apply mercurial ointment over the liver or testicle, since it had, as they expressed it, to go its rounds through the whole system, before it could affect either of these organs. This reasoning has an appearance of plausibility, but it is con- tradicted by facts. Numerous examples might be cited to prove that the greatest advantage may be derived from the local applica- tion of mercury, independent of any effect produced by it on the general system. How often do we see an incipient bubo dispersed by mercurial frictions, before any constitutional effects occur? How frequently do we see laryngeal and hepatic inflammation relieved by the use of mercurial ointment without salivation ? Do the beneficial effects, which we so often observe from the emplas- trum ammoniaci cum hydrargyro, depend necessarily upon the 68 graves’s clinical lectures. mouth being affected ? Is the relief which follows the use of mer- curial ointment in erysipelas or testitis, unattainable unless pre- ceded by mercurial action in the whole system? Indeed, any person who reviews this subject dispassionately, will see that the doctrine of a preliminary constitutional affection being absolutely necessary, in order to obtain the specific action of mercury on any particular organ, is wholly untenable; while, on the other hand, there is a host of evidence to prove that, locally applied, it produces a primary and distinct effect, totally independent of its action on the general economy. The last case to which I shall direct your attention, is one of syphilitic iritis. A young man has been admitted this morning, presenting symptoms of secondary syphilis in a well marked form, but simple and incomplicated by any previous treatment. He took no medicine for the primary or secondary symptoms, except two pills, which he got at a dispensary about two months ago, and which were not followed by any sensible effect. The secondary symptoms came on with pains and feverishness, and are at present extensively diffused over his body in the form of elevated blotches, of a character intermediate between the papular and squamous. About four or five days back, he was advised to take a warm bath for his pains, but having to walk a considerable distance afterwards, the day also happening to be chilly and sharp, he got cold in re- turning home, and soon after experienced pain in the left eye, with lachrymation, and diminution of the power of vision. Had he been exposed in the same way while in health, he would probably get slight conjunctivitis, or sore throat, or bronchitis; but the case was altogether different with a man labouring under a constitutional affec- tion, having a tendency to manifest itself in almost every tissue of the body, and prepared to modify every form of inflammation to which accident might give rise. Again, if the man’s constitution was in a sound state, his feverish cold, or conjunctivitis, or sore throat, could be removed by very simple means, such as bathing the feet, taking a little warm whey on going to bed, and some opening medicine the next morning. But here the state of the constitution occasions the substitution of syphilitic iritis for simple conjunctival inflammation, and demands a peculiar plan of treat- ment. You are all aware, that persons who have taken mercury for syphilis, without being entirely cured, are very liable to get iritis on slight exposures. Some persons attribute this entirely to the mercury; but mercury, in such cases, merely acts by rendering the patient more liable to cold, so that when iritis occurs in a patient who has been under a mercurial course, it is not in conse- quence of the direct operation of mercury, but by its increasing his liability to be affected by impressions from cold. For the same reason, the circumstance of his having taken mercury before, is not, as some persons maintain, any argument against his using it a second time. On examining this man, we found that he had some pain re- ferred to the eyebrow ; the eye also is more vascular than natural, SYPHILITIC IRITIS. 69 and presents that appearance which is so characteristic of iritis ; there is some alteration in the colour of the iris along its free margin, but no irregularity of pupil. Along with these symptoms, there is dimness of vision, and objects appear as if seen through a veil. This arises not from any opacity of the cornea, or opales- cence of the aqueous or vitreous humours, but from inflammation affecting the iris, ciliary zone, and, probably, the coats of the retina. In such cases, where the inflammation spreads from the iris to the ciliary zone, it would appear that the ciliary nerves and retina par- take in the mischief, for vision becomes affected before we can dis- cover any appearance of derangement in the optical instrument. The peculiar appearance of the eye in this man, the change of colour in the free margin of the iris, and the diminution of the power of vision co-existing with an eruption of the skin, point out the nature of the disease, and show that the affection of the eye, though proceeding from a common cold, has been modified by the syphilitic taint in the constitution. We next come to consider the plan of treatment to be pursued. In order to prepare his system for mercury, I have ordered him to be blooded, purged, and put on the use of antimonials for two or three days. Venesection, purging, and tartar emetic, may be of some use in relieving or arresting the symptoms of iritis, but I do not place any great reliance on them for removing the disease ; I merely employ them as auxiliaries, depending on mercury for the cure. Here it may be necessary to observe, that there is con- siderable variety in cases of iritis. Some are extremely mild; there is no palpable sign of acute inflammation present, and the chief symptom is diminution of the power of vision. Such attacks are sometimes not perceived by the patient until some accident informs him that the sight of one eye is nearly gone. In other cases, after reaching a certain point, it begins to decline, and fre- quently terminates spontaneously. Others present symptoms of a more decided character, but still are free from danger. Every attack, however, where the inflammation is at all of an intense character, will go on to destroy vision, unless met by prompt and efficacious treatment. Tn this man’s case the symptoms are not very acute, and hence there is no necessity for having recourse to mercury at once; the disease might certainly terminate in disor- ganisation of the eye, but it would be some weeks before this would be accomplished. On the other hand, there are cases which, if neglected, would destroy vision irremediably in the space of three or four days. Such cases require extremely prompt and energetic measures. But where iritis is not of a violent kind, you need not depart from the plan of treatment you would have laid down for the cure of syphilitic affections where no iritis existed. Here you bleed, purge, give antimonials and mercury, and you find that the syphilitic eruption and iritis disappear together. But where the symptoms of iritis are so severe as to threaten rapid disorganisation of the eye, you disregard the syphilitic affection, and direct your entire attention to the preservation of the eye. Here you bleed, 70 graves’s clinical lectures. leech, apply belladonna to the eye, and give calomel, in doses of ten grains or a scruple, every third or fourth hour, so as to bring the system as rapidly as possible under the influence of mercury. With respect to belladonna, I believe you are all aware of its value in iritis. Some think that its action is merely mechanical, that it dilates the pupil and no more; but I am firmly convinced that its influence is not limited to mere dilatation of the pupil. I believe that it acts on the vitality of the eye, and that when employed externally or internally, it possesses the properties of diminishing the irritability of that organ, and thus tends indirectly to remove local inflammation. In scrofulous ophthalmia, where the eye is exquisitely sensible, where the slightest exposure to light causes intense pain, and copious lachrymation, one of the best remedies I am acquainted with is belladonna, given internally. Thus, you perceive that belladonna has not only a mechanical action, producing dilatation of the pupil, and tending to prevent adhesions, but also, by its influence on the retina and ciliary nerves, diminishes the irritability of the eye, and aids materially in effecting the removal of local inflammation.

General remaiks on the pathology of paralysis—Dr. Graves’s new views upon this sub- ject—Their application to the study of several varieties of paraplegia—Explanation of Mr. Stanley’s cases of paraplegia; of Dr. Stokes’s cases—Two cases of paraplegia after enteritis—Paraplegia after metritis—Paraplegia the consequence of poisoning by lead; by arsenic—Paraplegia arising from irritation of the urethra, (case commu- nicated by Dr. Hutton.) Having recently met with some very interesting and remarkable cases of impairment of the muscular functions of the lower extre- mities, I am anxious to offer a few observations on paraplegia, par- ticularly while the subject is still fresh in my mind: we can resume the consideration of our clinical cases at a future opportunity. I would entreat your favourable attention on this occasion, while I lay before you some opinions on paraplegia peculiar to myself, and differing from the views entertained by the generality of medical writers; the subject, too, is one of extreme interest, involved in much obscurity, and offering an extensive field for investigation : I trust, however, I shall be able to communicate some new matter calculated to throw much additional light on the nature of this affection, and thus contribute to fill up the blanks which exist in an important department of pathological medicine. You are aware that by paraplegia is meant that species of para- lysis in which the lower extremities are affected—a paralysis fre- quently embracing loss of motion and loss of sensation in the lower extremities, accompanied in many instances with derangement of the motor power of the bladder and rectum. Now, I wish you PARAPLEGIA. 71 clearly to understand that it is not my intention to describe the symptoms, or discuss the causes, of those species of paraplegia which are well ascertained, and of which you will find satisfactory descriptions in your books: under this head may be classed all those cases which are produced by disease of the spinal marrow, its membranes, the vertebrae or their appendages, their ligaments, and diseases directly affecting the great nerves which supply the lower extremities. All these matters have been sufficiently studied, and require no additional observations from me; my object is to elucidate some of the obscurer varieties of paraplegia. I have touched on this topic before in my lectures delivered at the Meath Hospital, but since that time I have met with many cases, and made enquiries which tend to throw additional light on the subject. I have read, with the attention which it merits, a lecture on this subject, published by my colleague, Dr. Stokes, in Renshaw’s Lon- don Medical and Surgical Journal, and also Mr. Stanley’s inte- resting cases in the 18th volume of the Medico-Chirurgical Trans- actions, published in the year 1833. In Mr. Stanley’s paper, several cases of paraplegia are brought forward, the explanation of which had not been understood before or even at the time he wrote, but which I had given several months previously, as applied to paralysis in general, in two lectures in the 58th and 59th numbers of the London Medical and Surgical Journal, and which had been delivered at the Meath Hospital, in Nov. 1832, and were pub- lished immediately afterwards. In fact, the explanation offered by Mr. Stanley is merely a corollary of the propositions which I laid down at that time, and which I shall beg leave to repeat here. Before I commenced my investigations on the subject, patholo- gists, in endeavouring to ascertain the causes of paralysis, sought for the sources of the disease almost solely in the centres of the nervous system. They looked for the causes of paralysis in the brain or spinal cord, where they supposed it originated either in organic or functional derangement of these important organs. In the lectures to which I have already referred, I showed that this mode of accounting for all forms of paralysis, by referring them to original disease of the nervous centres, was in many instances in- correct, and proved, I think to the satisfaction of the class and those who read the lectures, that a most important and influential cause of paralysis had been hitherto nearly overlooked—a cause which, commencing its operation on the extremities, and not on the centres of the nervous system, might, by a reflex action, produce very remarkable effects on distant parts. I brought forward on that occasion many arguments, facts, and cases, to prove the possibility of such an occurrence—to show that it frequently happens that impressions made on the extremities of the nerves will generate a morbid action in them; that this morbid action will be conveyed along their branches and trunks to the spinal cord or brain ; and that, continuing its propagation, it may, by a retrograde course, be carried thence along the nerves to distant organs, and in this way give rise to disease in parts originally intact and healthy. I brought 72 graves’s clinical lectures. forward several instances to prove that, when a certain portion of the extreme branches of the nervous tree has suffered an injury, the lesion is not confined merely to the part injured, but in many instances is propagated back towards the nervous centres; and that, in this way, not only the nervous filaments of the injured part may be affected, but also the main trunk of the nerve and other branches, or that the lesion may reach the brain or spinal cord, and thus produce still more extensive effects on the system. What I endeavoured to impress upon the class at that time was, that pain, numbness, spasm, and loss of the power of muscular motion, may be produced by causes acting on the extremities of the nerves; and that such affections, commencing in the extremities of the nerves, may be propagated towards their centres so as to be finally confounded with diseases originating in the centres them- selves. For a detailed account of my views on this subject, I beg leave to refer to the published lectures; at present I shall content myself with recapitulating a few of the facts on which these views were grounded. If you place your hand in snow or ice-cold water, you will find that it is not merely the parts subjected to the influence of cold that become numb, and that the diminution of power is not entirely limited to the muscles concerned in the peculiar motions of the fingers, but extends also to those of the fore-arm, by which the principal motions of the hand are performed. Here the impression of cold is found to affect not only the parts immediately exposed to it, but also parts that are quite removed from its influence and warmly covered. We see that not only the muscles attached to the fingers, but also those of the fore-arm, undergo from this cause a temporary paralysis. Now, if a cause of a trifling nature, and acting only for a time, can, when applied to a part, produce loss of power in another and more central part, we may infer that the same cause acting permanently might produce permanent paralysis of the latter. We can, therefore, conceive how in this case the agency of cold might travel upwards and reach the muscles of the arm also, and thus we should have a change, commencing in the tips of the fingers, propagated to parts at a considerable distance from the situation of the original lesion. Again, we find that an injury, affecting one branch of a nerve, will be propagated by a retrograde action so as to affect another and distinct branch, as was exemplified in a case mentioned in my former lectures on paralysis. A young lady, having wounded the inside of her ring finger with a blunt needle, observed that she had, in consequence of the injury, a considerable degree of numbness, not only in the wounded finger, but also in the little finger next to it. Here we find that an impres- sion made on the nerve of one finger not only affects that finger, but also travels backwards so as to operate on the branch given off by the ulnar nerve to supply the little finger—and given off\ ob- serve, above the place of the wound—so that the phenomena were identical with those which would arise from an injury inflicted on the branch which supplied both fingers. Within this last month, PARAPLEGIA. 73 I have had an opportunity of witnessing a very striking fact of this nature. A young gentleman, distinguished for the extent of his classical and mathematical acquirements, and who had just suc- ceeded in obtaining the senior wranglership, swallowed a small but angular piece of chicken-bone. It lodged low down in the oeso- phagus, and was not pushed, by means of a probang, into the stomach until after the lapse of more than an hour. Considerable inflammation of the pharynx, oesophagus, and surrounding tissues, was the consequence; on the third day of his illness he got a vio- lent, long continued, and ague-like rigor, which terminated in a profuse perspiration, and ushered in a well-marked inflammation of the neck of the bladder. In the next place, we find that impres- sions affecting the frontal branches of the fifth nerve may, by a reflex action, operate on the retina so as to cause blindness. Here the morbid action travels from the circumference towards the centre, and is again reflected towards the circumference so as to affect a separate and distinct part. Of this I lately saw a curious and instructive example. A medical student, traveling through Wales on the outside of the mail, was exposed for many hours to a keen northeasterly wind blowing directly in his face. When he arrived at the end of his journey, he found that his vision was impaired, and that every thing seemed as if he was looking through a gauze veil. There was no headache, no symptom of indigestion, to ac- count for this evidently slight degree of amaurosis, and yet he was recommended to use cupping to the nape of the neck, and strong purgatives. When he consulted me, which he did in the course of a few days afterwards, I at once saw that there was something un- usual in the case; and, after a careful examination, I at length elicited from him the fact of his having been exposed to the influ- ence of the cold wind. It was now apparent that the retina suffered in consequence of an impression made on the facial branches of the fifth pair. The cure was effected, not by a treatment directed to relieve cerebral congestion, but by stimulation of the skin of the face, forehead, temples, &c. It is, however, unnecessary to multiply examples to prove the truth of the proposition, that disease may commence in one portion of the nervous extremities, and be propagated towards the centre, and hence, by a reflex action, to other and distant parts. Bearing this in mind, we can explain why it is that disease commencing in one part of the system may produce morbid action in another and distinct part, and it certainly appears strange, that, with so many striking examples before them, pathologists should have so long overlooked this cause, when seeking to explain the nature of many forms of paralysis. If certain irritations of the nervous extremities in one part of the body are capable of giving rise to a derangement in the whole system of voluntary muscles; if a local affection may become the cause of exalting and rendering irregular the functions of every muscle in the body; then, surely, it is not difficult to con- ceive that a cause, local as the former, and tending not to exalt but to depress the motor function of the muscles, may likewise affect 74 graves’s clinical lectures. not merely the nerves and muscles of the part, but also those of the whole body, or of distant organs, giving rise to paralysis. Now, pathologists have long recognised the fact, that general muscular excitement and spasm may arise from the operation of a local irri- tation. A man gets a contused wound on his thumb, or one of his fingers, and some superficial nerves are injured. In the course of a few days he begins to feel a degree of stiffness about the lower jaw and muscles of the neck, accompanied by a sense of constric- tion about the diaphragm. This increases gradually, all the volun- tary muscles are thrown into a state of fixed spasm, and he gets tetanus. Here a few trifling branches of the digital nerves are injured, the morbid action is conveyed from them along the nerves of the arm to the spinal cord and brain, and is thence, by a reflex action, propagated all over the body. A wound of the finger causes a morbid action in its nerves, and it has been acknowledged by pathologists that this, by acting on the brain and spinal cord, may give rise to a general morbid action of the muscular system. This being the case, there is nothing improbable in supposing that a cause affecting any portion of the branches of the nervous tree, and which produces effects of a paralytic nature, may likewise react backwards towards the nervous centres, and thence, by a reflex progress, may extend its influence to distant parts of the circumfe- rence. To give another instance : how often do we see irritation, com- mencing in the intestinal mucous membrane, propagated backwards towards the brain ? Take the familiar example of intestinal worms. A child labours under worms; here the irritation of the digestive mucous surface, whether it be produced by the worms, or by the indigestion which accompanies them, is propagated from the sto- mach and bowels to the brain, and thence reflected to the volun- tary muscles, causing general convulsions. Dr. William Stokes details the following case in his lectures. “ A young woman was admitted into one of the surgical wards of the Meath Hospital, for some injury of a trivial nature. While in the hospital, she got feverish symptoms, which were treated with purgatives, consisting of calomel, jalap, and the black bottle, a remedy which deserves the name of coffin bottle, perhaps, better than the pectoral mixture so liberally dealt out in our dispensaries as a cure for all cases of pulmonary disease. She was violently purged, the symptoms of fever subsided, and she was discharged. A few days afterwards, her mother applied to have her readmitted, and she was brought in again, and placed in one of the medical wards. Her state on admission was as follows :—She had fever, pain in the head, violent contractions in the fingers, and alternate contraction and extension of the wrist and fore-arm. These mus- cular spasms were so great, that the strongest man could scarcely control the motions of the left fore-arm. In addition to these symptoms, she had slight thirst, some diarrhoea, but no abdominal tenderness. On this occasion, a double plan of treatment was pursued, the therapeutic means being directed to the head, in con- PARAPLEGIA. 75 sequence of the marked symptoms of local disease of the brain, and to the belly, from the circumstance of abdominal derangement observed in this and her former illness. She died shortly after- wards, with violent spasms of the head and fore-arm; and as she had presented all the ordinary symptoms of a local inflammation of the opposite side of the brain, we naturally looked there first for the seat of disease. After a careful examination, however, no per- ceptible trace of disease could be found in the substance of the brain, which appeared all throughout remarkably healthy. She had all the symptoms which, according to Serres and Foville, would indicate disease of the optic thalamus or posterior lobe of the oppo- site side, yet we could not find any lesion whatever of its substance, after the most careful examination. But on opening the abdomen, we found evident marks of disease; the lower third of the ileum, for the length of six or eight inches, was one unbroken sheet of recent ulcerations.” This case, gentlemen, you will perceive just now, bears very strongly on the subject of paraplegia arising from enteritis. Again : how often do we see convulsions brought on in the same way by cutaneous irritation ? A child gets an attack of fever, accompanied by general irritability and restlessness. During the course of the disease, the lungs become affected, and the medical attendant applies a large blister, which is left on for several hours. Next day the symptoms of nervous irritation become more violent; the child is perfectly restless, or, if it dozes for a moment, awakes screaming, and is finally attacked with general convulsions. Many other examples could be brought to support this view of the ques- tion, and prove that morbidly increased action of the whole mus- cular system may be excited by a cause acting merely on some insulated portion of the nervous extremities. I think, therefore, that I am borne out by analogies strikingly exhibited by numberless examples, in asserting that the circumfe- rence of the nervous system has been too much neglected by patho- logists, in their explanations of the nature and causes of paralytic affections. I could give many instances of pains commencing in particular parts of the body, and traveling back towards the spine, so as to give rise to an affection of that organ, which has been too generally looked upon as the result of idiopathic disease. How often does this happen in hysteria? How often does it happen that the organ primarily engaged in hysterical cases becomes, during the attacks, acutely painful, and that, as the disease proceeds, the pain travels back towards the spine, until at length the spinal cord itself becomes affected, and we find acute pain and tenderness over some portion of its track ? I am fully persuaded that many modern authors, who have ascribed the phenomena of hysteria and other affections to spinal irritation, have been too hasty and indiscrimi- nate in their explanations. In the majority of cases, you will find hysteric patients complain at first, not of pain in any part of the spinal cord, but in the right side in the situation of the liver, in the region of the heart or stomach, or in the head, or the pelvic region. 76 graves’s clinical lectures. At this period there is seldom any tenderness over the spinal cord; but, as the disease goes on, the irritation which existed in some of those situations to which I have referred, is extended to the spine, and pain and tenderness are now felt over some of the spinous pro- cesses of the vertebrae. When this has taken place, then the spinal irritation thus produced becomes itself a new cause of disease, from which, as a centre, the morbid influence is propagated to other organs. The profession owe much to Teale, Griffin, and other writers, who have pointed out the importance of attending to this spinal tenderness in cases of hysteria, &c. Still, however, like all those who have been employed in investigating a new subject, they have perhaps generalised too hastily, and have, in many cases, regarded this spinal tenderness as a cause, when it should have been merely considered as a consequence. Having thus endeavoured to explain some of the general prin- ciples which should guide us in the investigation of nervous dis- eases, I shall relate some cases of paraplegia, which, though differ- ing in their origin as to the organ inflamed, will strike you as exhibiting a close analogy to those published by Mr. Stanley. “In November, 1832, I attended, with Mr. Kirby and Mr. Cusack, a young gentlemen, aged fourteen, who was residing at a boarding school in the vicinity of Dublin. He had eaten a large quantity of nuts on the eve of Allhallows, and had, in consequence, obstruction of the bowels, attended with sense of weight and pain of the sto- mach, nausea, loss of appetite, and obstinate constipation. Active purgatives, of different kinds, were employed without effect, and the obstruction was only removed by the use of repeated enemata, thrown up with Read’s syringe, introduced as far into the cavity of the intestine as the circumstances of the case permitted. To these means, assisted by leeching and stuping, the constipation yielded; but its removal was followed by symptoms of enteric inflammation, embracing not one, but all the coats of the intestine—the mucous, the muscular, and certainly the peritoneal. The occurrence of a new and violent disease greatly impeded his cure; we had a long and anxious attendance, and the young gentleman escaped with great difficulty. However, the enteric symptoms at length gave way, convalescence became manifestly established, the patient was able to sit up in his bed, and as his strength and appetite were rapidly returning, he was informed that he might get up. On attempting to leave his bed, it was found that he had lost the power of using his lower extremities—in fact, he had become paraplegic. He had perfect power over his arms and trunk, but the lower extre- mities were quite useless. The paralysis, however, was entirely limited to the muscles; there was no diminution of sensibility in the limbs; no numbness, pain, or sensation of formication; and the muscular functions of the bladder and rectum were, apparently, uninjured. Before I enter on the explanation of this case, permit me to recite the following:—In the month of November last, I was called to visit a lady residing in the neighbourhood of Merrion PARAPLEGIA. 77 square, who was said to be labouring under symptoms of dyspepsia. She had a sense of weight about the stomach, nausea, tendency to vomit, epigastric and hypochondriac tenderness, (the latter situated in the right side,) but no fever or excitement of the circulation. In the course of two or three days, she became slightly jaundiced, and it was evident that the latent cause of her disease was, in all pro- bability, a gastro-duodenitis terminating in an affection of the liver. It is sufficient to say that this lady’s symptoms went on, and that the diseased action gradually extended to the whole intestinal tube, liver, and peritoneum. Her bowels became tympanitic, her belly extremely tender on pressure, she got low fever, with quick pulse and great restlessness, and was saved with difficulty by the repeated application of leeches, and the use of calomel so as to affect the mouth. She became convalescent; but with the return of health, it was found that she had lost the power of using her lower extre- mities. She still continues paraplegic. In the case of the young gentleman already detailed, you will recollect that the paralysis was entirely limited to the muscular functions of the lower limbs, and that there was no derangement of sensation, no lesion of the muscular powers of the rectum and bladder. The same thing occurred in this case. There was in the beginning no impairment of sensibility, and the power over the rectum and bladder was uninjured. “Within the last three weeks, however, she has complained of pain in the loins and bowels, and the muscular functions of the bladder are becoming deranged.”1 Indeed, the case is rather unfavourable ; it has resisted the ordinary remedies, and threatens to become one of confirmed paraplegia. It is to be observed, that in this lady the loss of power was much more complete that in the young gentleman before referred to; his paraplegia was by no means perfect, and yielded to the employment of stimulating frictions to the extremities, combined with a cautious use of internal stimulants and tonics. In neither of these cases was the loss of muscular power so great as to deprive the patients of the use of their legs while lying in bed. They could then be raised, flexed, and extended with apparent ease and strength ; and yet, when the patient attempted to stand up or walk, he was totally unable to do either, his legs sinking under him; and even when supported by a person at each side, so as to take the greater part of the weight of the body of!'the limbs, he was still unable to advance one foot before another. I cannot understand why so great a dif- ference should exist between the muscular force of the legs in the one position and in the other. Here, you perceive, we have more or less complete loss of power of the lower extremities, supervening on inflammation of the gas- trointestinal mucous surface. Of this I have now witnessed seve- ral examples. How are we to account for this? In what way does paraplegia arise from inflammation of the bowels? The mode in which I would explain this phenomenon is as follows:— 1 This sentence was inserted on the 23d March, 1835. Mr. Carmichael and Dr. Nalty have seen this lady repeatedly. 78 GRAVE,s’s CLINICAL LECTURES. The impression made by inflammatory derangement on the nervous filaments distributed to the mucous coat of the intestines is propa- gated to the spinal cord, and from this reacts on the muscular func- tions of the lower extremities. It is true that the intestines, and most of the abdominal organs, are almost exclusively supplied with nerves from the great sympathetic; but you are to recollect that these communicate by numerous branches with the spinal nerves, and that, consequently, morbid impressions made on their extremi- ties may be rapidly and extensively propagated to the spinal cord, and from thence by a reflex action to the muscular nerves of the lower extremities. When I first met with cases of paraplegia after inflammation of the bowels, or fever with gastro-enteric symptoms, I thought that, owing to some peculiarity in the case, the great lumbar nerves had become implicated in the disease; that there was an actual inflammatory state of the neurilema, accompanied by thickening and effusion, which, by compressing the nervous matter, gave rise to the paraplegic symptoms. A more extensive review of the subject, however, has convinced me that this is not the fact; for, if it were, the affection of the nerves would naturally be attended with acute pains shooting in the direction of their course—for, as far as my experience goes, in every instance of in- flammation attacking the neurilema, intense pain is felt in the parts to which the branches of the affected nerve are distributed. Again, though this explanation might apply to cases in which the inflam- mation was general—as where enteric is combined with peritoneal inflammation—it would not apply to those cases in which the inflammatory action is localised. Thus, in Mr. Stanley’s cases, the paraplegia supervened on inflammation principally limited to the kidneys. In seven cases detailed in Mr. Stanley’s paper, we find paralytic symptoms produced, not by any derangement commenc- ing in the brain or spinal cord, but in consequence of an irritation having its seat and origin in the kidneys; and yet, in the majority of his patients, the paraplegia was as complete as if it had been produced by idiopathic disease of the cord or its investments. What was equally remarkable, many of those cases were accom- panied by spinal tenderness; so that the most experienced practi- tioners, on a review of the symptoms, were inclined to look upon them as cases of disease affecting the vertebras, or the spinal cord and its sheath. Yet on dissection there was no caries of the bones; no destruction of lisraments; no remarkable vascularity, softening, or suppuration of the spinal cord; no inflammation of its mem- branes, or effusion into its sheath. In almost all, the morbid phe- nomena were confined to the kidneys; there were depositions of pus dispersed through their substance, and the mucous lining of the infundibula, ureters, and bladder, was thickened and vascular. The formation of purulent matter was not, however, connected with the paraplegia further than as being, like it, produced by the same cause—inflammation of the kidney. In one case the para- plegia was very complete, and yet the inflammation of the kidney had not advanced to the stage of suppuration. PARAPLEGIA. 79 There can be little doubt that others have frequently noticed the occurrence of paraplegia after inflammation of the bowels, although no author has as yet written upon the subject. It is well to be ac- quainted with the occasional occurrence of so untoward and obsti- nate a sequela of enteric inflammation, in order that we may watch attentively the state of the lower extremities immediately after the inflammation of the bowels has been subdued. As the patient, in such cases, has no pains in his limbs, and is not conscious of any loss of power until he attempts to stand up—and as this attempt is not usually made for many days after the subsidence of the inflam- mation of the bowels, in consequence of the great debility which the disease and the active treatment necessarily resorted to produce —this variety of paraplegia is very liable to be overlooked in its commencement, and is thus neglected at the very period when treatment is most likely to prove beneficial. The foregoing observ- ations have, no doubt, excited a suspicion in the minds of some of you, that the paralysis so often observed to follow painter’s colic may be derived from a reaction of the nervous system of the bowels on that of the muscular system in general. Dr. Bright, indeed, has asserted that inflammation of the spinal marrow or sheath, as denoted by spinal tenderness, always precedes the paralysis pro- duced by lead. It often does, but by no means constantly; for I have pointed out to you several cases in this hospital in which not the slightest vestige of spinal tenderness could be detected either before the commencement, or during the progress, of the paralysis which so often follows painter’s colic. I am not inclined to adopt the supposition that the paralysis in such cases is merely secondary, and the result of the intestinal irritation. I think it much more probable that it depends on the poisonous effects of the lead acting directly on the nervous system. The same observation applies to the paralysis which so often occurs as a result of large doses of arsenic. Orfila has remarked that some of the dogs he experi- mented on, and which narrowly escaped dying in consequence of large doses of arsenic, became, when they recovered from the imme- diate effects of the poison, permanently paraplegic. I look upon this paralysis as a direct consequence of the deleterious action of arsenic on the nervous system, and not as the result of the gastro- enteritis it invariably produces. The fact, however, is well worthy of attention, that both arsenic and lead produce intestinal irritation in the first instance, and loss of muscular power in the second. A knowledge of this fact will prepare us for understanding the con- nection which appears to exist between intestinal irritation and paralysis. In a lecture published by my colleague, Dr. William Stokes, in the 137th number of the London Medical and Surgical Journal, he makes the following observations, which I shall beg leave to quote:—-Here, then, we have well-marked paraplegia without any perceptible organic change in the spinal cord or its investments, but presenting distinct traces of disease in the kidneys. This leads me to observe the very close connection which exists between the kid- 80 graves’s clinical lectures. neys and spinal cord—a connection which has been long recognised by medical practitioners, but only in a limited point of view; for, though they were of opinion that disease of the kidneys and a dis- charge of ammoniacal urine were the results of spinal disease, they never seem to have reflected that the reverse of this might happen. It seems, however, now to be almost completely esta- blished, that disease of the kidneys may produce symptoms which are referable to disease of the spine. Medical men have been too much in the habit of looking at this matter only in one point of view. They know that disease of the spine will produce disease of the kidneys, and here they stop; but it has been shown that the reverse of this may happen, and that renal disease may produce very remarkable lesions in the functions of the spine. Of this very curious occurrence we have many analogies in pathology. Thus, for instance, in several cases of cerebral disease, but particularly in hydrocephalus, we have vomiting; here we have functional disease of the stomach depending on disease of the brain. Take the reverse of this,—observe the delirium which attends a case of gastroente- ritis ; here you have the functions of the brain deranged in a most remarkable manner, and this produced by sympathy with an in- flamed mucous membrane. The truth is, that in the spine and kidney, as well as in various parts of the body, we may have two organs so closely connected in sympathy, that disease of the one will bring on serious functional lesion of the other.” It will be seen that these observations coincide, in many points, with the principles I have laid down in the published lectures which I delivered on the subject of nervous pathology, and to which I have already referred. On this point Mr. Stanley makes the following remarks:—“In reflecting on the phenomena of the first series of cases which have been detailed in this paper, it might be thought improbable that irritation, commencing in the kidney or in the bladder, should be propagated through sentient nerves to the spinal cord, and that the impression should thence be transmitted through both the motive and sentient spinal nerves to the limbs— here occasioning an impairment both of sensation and of the power of motion. Some illustration of this subject seems to be furnished by the researches of experimental physiology. If, in an animal, ‘a few seconds after it has been deprived of life, the spinal cord be then divided in the middle of the neck, and again in the middle of the back, upon irritating a sentient organ connected with either isolated segment, muscular action is produced—that is to say, a sentient organ is excited—and an irritation is propagated through the sentient nerve to the isolated segment of the spinal marrow, where it gives rise to some change, which is followed by an impulse along the voluntary nerves to the muscles of the part.” In the instances which have been adduced, irritation, commencing in the nerves of an internal organ—the kidney—has been transmitted through the spinal cord to the motive and sentient nerves of the 1 Outlines of Human Physiology, by H. Mayo. PARAPLEGIA. 81 lower extremities; but the same phenomena may occur in an oppo- site order, as in the case of a compound fracture or other severe injury of the lower extremity, followed by retention of urine from irritation arising in the anterior crural and ischiatic nerves, and communicated through the lumbar and sacral plexuses of spinal nerves to the nerves of the bladder. Extending these views to cases of neuralgia where there is no visible derangement of struc- ture or other local cause of excitement, it will always be difficult to determine whether the source of irritation be in the affected nerves, or in the central portion of the nervous system whence they are derived.” You will perceive that this explanation, as far as it goes, though not in the same words, is in meaning the same as that which I have given, with this exception—that it is only a corollary of the general principles which I had laid down in my lectures on the pathology of the nervous system. Long before the publication of Mr. Stanley’s paper, I had established the proposition that impres- sions made upon any portion of the nervous extremities may be propagated towards their centres, and thence by a reflex action transmitted to the nerves of other and distant parts, so as to give rise to morbid phenomena analogous to those which are produced by disease originating in the central parts themselves. Applying this principle to the subject of paraplegia, we shall find that, inde- pendently of cerebral or spinal disease, it may arise from a variety of causes, each referable to lesions commencing in distinct and iso- lated portions of the nervous extremities. Thus, in Mr. Stanley’s cases, the exciting cause seems to have originated in the urinary system; in the cases which I have detailed, where it supervened on inflammation of the bowels, it commenced in the digestive (and it appears, from a communication made to Mr. Stanley by Mr. Hunt, of Dartmouth, that the same thing may result from irritation exist- ing in the uterine) system. Mr. Hunt alludes to several cases of disease of the uterus being followed by such loss of power in the lower limbs, that the patients were entirely confined to bed; adding that there was no change of structure in the parts to which the symptoms referred as the source of irritation. Jn addition to these, I shall in my next lecture bring forward several cases to prove that a similar loss of power may be produced by the action of cold on the lower extremities. Indeed, the number of cases which I have recently met with, where paraplegia was evidently brought on by exposing the lower extremities to cold and wet, has very strongly directed my attention to this form of the disease; and I trust I shall be able, at our next meeting, to communicate some very interesting matter on the subject. I shall conclude this lecture by reading the following case, for which I have been indebted to the kindness of my friend Dr. Hutton. “ Richard M‘Nab, a sailor, aged thirty-eight, was admitted into the Richmond Hospital on the 16th of January, 1835, and placed under Dr. Hutton’s care. His previous history was briefly as 82 graves’s clinical lectures. follows:—In the summer of 1826 he strained his back in leaping, and was confined to bed in consequence of the accident, but reco- vered in about twelve days. Shortly afterwards he contracted gonorrhoea, which was attended with hernia humoralis; this yielded to repeated local bleeding, but a gleet remained, and this, after con- tinuing for some time, disappeared under the use of sea-bathing. He then enjoyed good health, with the exception of occasional slight pain in the lumbar region, until October, 1830, when, being much exposed to cold and wet during a long and fatiguing voyage, he got an attack of piles, for which he was under medical treat- ment for seven months. During the continuance of this affection, he first observed a frequency in micturition, but had no retention or sensible obstruction of urine. After recovering from the hsemor- rhoidal attack, he enjoyed good health until September, 1834, when, coming from Cadiz to the port of Dublin in a very leaky vessel, he suffered greatly from cold, wet, and fatigue—being almost con- stantly engaged at the pumps, which could not be left for ten minutes at a time. In addition to this, being deprived of his usual allowance of spirits for thirty-two days, he found himself, on his arrival in Dublin, in a very weak state. He rested from his occu- pation for a fortnight after discharging his cargo, and states that during this time he drank from four to six glasses of whiskey daily. He then went on board the Elizabeth, of London, as chief mate, but after eight or nine days his back and lower extremities became affected with pain and weakness, which increased to such a degree that he was obliged to give up his occupation on the thirteenth day. He states that, during the time his back and legs were getting weak, he was obliged to pass water about three times in an hour, which he did with pain and tenesmus. On the 1st of January the pain of his back was very severe, and he lost the use of his limbs, but not completely, for he could support himself, and even walk a little with the aid of two sticks. “At the time of his admission he appeared somewhat broken down in his general health ; he was pale, emaciated, and laboured under derangement of his digestive organs. He suffered from occasional chills, succeeded by heats and sweating, which occurred at irregular periods; he also laboured under micturition, dysuria, and the stream of urine was much diminished ; the weakness and loss of power in his lower extremities as reported. “ His treatment was as follows :—First, cupping over the loins, then moxas in the same situation; attention to his digestive organs; diluents and opiates for the urethral symptoms. On the 26th of the same month, a very close stricture was found to exist in the membranous portion of the urethra. A small catgut bougie of double length was introduced, so that one half of it projected from the meatus; over this was slided a small gum-elastic catheter of ordinary length, and open at each end, until it traversed the stric- ture and reached the bladder; the catgut bougie was then with- drawn, and the gum-elastic catheter secured. A little constitutional disturbance followed, but soon subsided, and in a few days gum- PARAPLEGIA. 83 elastic catheters of a much increased size were introduced with facility. “ A very remarkable amendment took place in his back and lower extremities, in a very few days after the first introduction of the instrument; in fact, it teas almost sudden. Warm baths, friction to his limbs, &c., completed his cure. He was discharged on the 25th of February, at which time the power of his lower limbs was perfectly restored, and the symptoms affecting the urinary system had disappeared.” You at once perceive the extreme importance of this case; it bears directly on the question before us, and proves that urethral irritation may, as well as inflammation of the kidneys, give rise to paraplegia ; and it affords another striking illustration of the gene- ral proposition which I have laid down. LECTURE VIII. In my last lecture, I gave a brief summary of the opinions which I had published on the subject of nervous pathology, in the year 1833, and showed that the principles there laid down were entitled to serious consideration, as connected with the explanation of many forms of paralysis hitherto not well understood. I trust I have proved, to your satisfaction, that the nervous extremities have been too much overlooked by medical writers in seeking to explain the source and origin of paralytic affections; and that many cases of loss of the power of motion and sensation can be clearly traced to the agency of causes acting primarily on the sentient extremities of the nervous system. I adduced numerous facts to show, that an impres- sion made upon some portion of the extremities of the nerves may be propagated towards their centres, and transmitted thence to other and distant parts, producing there pain, spasm, impairment of sen- sibility, and diminution or total loss of muscular power. With reference to the subject of paraplegia, I cited the cases published by Mr. Stanley, and expressed my opinion, that the loss of power in the lower extremities was the result of a morbid action com- mencing in the sentient nerves of the kidneys, and propagated through the medium of the spinal cord to the muscular and sentient nerves of the lower limbs; and I brought forward some new cases of paraplegia, supervening on inflammation of the bowels, with the view of illustrating the principles I had already laid down. In the next class of cases we have to consider, the cause of the paraplegia is extremely obscure—I mean those cases in which the paraplegia occurs during the course of fever. Here the other suf- ferings of the patient, and his general debility, attract our notice so exclusively, that the paralysis entirely escapes notice until conva- lescence is established—until, in fact, the patient wishes to support 84 graves’s clinical lectures. himself on his legs. He then finds, much to his surprise, that his limbs collapse under him, and that he has little or no power over them; this appears to him the more extraordinary on account of his having recovered a good deal of strength in his upper extre- mities. Thus, a Miss F. was attacked in fever, while on a visit to a friend in Dublin. She was attended by Mr. Carmichael. Her fever was protracted and severe, and exhibited, during its progress, well marked symptoms of gastro-intestinal irritation and congestion, viz., tympanitis, epigastric and abdominal tenderness, &c. When her convalescence was established, her attendants found, to their great alarm, that she had no power in her legs. She complained of coldness and numbness in the lower extremities. This lady gradually recovered the use of her legs, but not until moxas, with- out number, had been applied along the course of the spinal column. The cure lasted about a year. No evidence could at any time be detected, indicating disease of the spinal bones or liga- ments. Mr. Carmichael has seen several cases of paraplegia fol- lowing the remittent gastric fever of children, totally unconnected with spinal disease. Such an occurrence is most usual in children of a scrofulous temperament, and is seldom, very seldom, remedied either by time or medicine. Two explanations suggest themselves as capable of accounting for the paraplegia after fever. The first rests upon the frequency of the occurrence of violent pain in the small of the back in the commencement of this disease. This pain in the back is often excruciating, and generally accompanied by proportionally violent pains in the lower extremities. I am quite as anxious to relieve the pain in the back in the beginning of fever, as I am to remove headache; one is almost as serious as the other, for the vital importance of the spinal marrow in the economy is scarcely less than that of the brain. In reference to this point of practice, I have been in the habit of using the expression, (in order to fix the attention of my pupils,) that such a patient has not any pain in his head, but he has gotten his headache in the small of his back. Now, when headache is the prominent feature of the first stage of fever, how few will omit bleeding, leeching, cupping,, cold or hot applications, &c. &c. When, on the contrary, the lumbar spinal marrow is the seat of the congestion, how generally do practitioners neglect the applica- tion of topical bleeding, and other appropriate remedies. Were such neglect of less frequent occurrence, it is probable that paraplegia after fever would not so often be met with. Some may be inclined to look for the source of the paraplegia which follows fever in the irritation of the gastro-intestinal mucous surface, propagated by a reflex progress of the spinal marrow. It is not easy to decide be- tween these two explanations, but I confess myself more inclined to adopt the former than the latter. I shall now proceed to lay before you some facts and cases illus- trating the nature of another form of paraplegia, a form of extreme interest, from the circumstance of its being hitherto but little under- stood, and not mentioned by any writer I am acquainted with, as PARAPLEGIA. 85 well as from the peculiar nature of its origin, and the frequency of its occurrence. I have, within a comparatively short period of time, met with several instances of this affection, and have some cases of it at present under treatment. Before I enter on this part of the subject, I may be allowed to remark that, in some cases, loss of the power of motion in a limb can evidently be traced to the operation of a cause whose action is confined altogether to the surface. Thus, in the case of a woman in Sir P. Dun’s Hospital, erysipelas occupied the calf and inside of the right 4eg, and occasioned some inflammation and tenderness along the chain of lymphatics extending to the groin, where one of the inguinal glands was slightly enlarged and painful. The erysipelas yielded to the employment of local and general remedies; but, for several days, and particularly while the disease was at its acme, she was altogether destitute of any power of motion in the affected limb; she could neither bend the leg on the thigh, nor could she raise the whole limb. This affection must have been produced by a reflex action propagated from the cutaneous branches to the larger muscular nerves. It is evident, that the muscles which move the leg on the thigh could have been affected only in this way, for they lay far above the part in which the erysipelatous inflammation existed. It is in the same way that we are to account for the paralysis observed in cases of phlegmasia dolens. Sometimes the reverse of this happens, and a single limb be- comes paralysed, on account of an injury done to one of its prin- cipal nerves by the application of sudden violence, or of pressure long continued. Thus, a case was related to my friend Dr. Bren- nan and myself, in which a robust gentleman, having been much fatigued during the day, fell asleep after dinner, his head resting on his arms, which were crossed on the table. In consequence of some unfortunate awkwardness in his position, one of the ulnar nerves was compressed during the time he slept, and, on awaking, his fore-arm and hand were completely powerless. Many remedies were tried in this case without success, and the paralysis continued until the day of his death, which occurred several years afterwards. A lady, not long since, was tripped in walking across the floor, and fell with considerable force. The parts which sustained the prin - cipal shock were the left hip and trochanter. From the moment of the accident, she lost all power in the left lower extremity, which remained permanently paralytic. Fracture or dislocation was sus- pected at first, but a minute and careful examination showed that the suspicion was groundless. No injury of the spine could be detected, and she had no numbness, pain, or formication, in the affected limb. After a month, she was placed under the judicious care of Mr. Kirby, who used every topical application likely to prove useful, but without the slightest benefit. She returned to the country, where she died shortly afterwards, quite unexpectedly, in the bloom of life, and without the occurrence of a single symp- tom indicative of approaching danger. No autopsy was permitted. I shall now, with the view of illustrating the form of paraplegia 86 GRAVEs’s CLINICAL LECTURES. to which I have alluded, read the following very remarkable case, which I had an opportunity of tracing through all its stages, and which made a very considerable impression on me at the time. The history is chiefly derived from notes furnished by the patient himself before he became too weak to write; what relates to the latter stages of his complaint, is taken from my own case-book. Mr. B., aged twenty-three, was remarkably strong and healthy, though of a spare habit. He was able to take a great deal of exer- cise, capable of enduring much fatigue, and passionately fond of hunting, fishing, and shooting, particularly the latter ; and, in pur- suit of his favourite amusements, frequently exposed himself to wet feet during his excursions through bog lands, and when wading in the water. These habits, however, he laid aside after the occurrence of the first attack of his illness, which happened in 1829. He had for many years been of a costive habit, his bowels being frequently confined for a week at a time, but did not experience any sensible bad effects from this circumstance, and never took any aperient medicine. Since the first attack, in January, 1829, this state ceased, and his bowels became ever afterwards inclined to loose- ness, which always increased before the appearance of one of the attacks, accompanied by griping, nausea, and inclination to vomit. Each attack was generally preceded by a copious secretion of insipid watery fluid in the mouth, and then the characteristic symptoms of his disease commenced. These consisted in obstinate and protracted nausea and vomiting ; he first threw lip whatever happened to be on his stomach at the time, and afterwards every thing he swallowed, whether solid or liquid. The matter ejected was at first acid and afterwards bitter, varying in colour from mucous to bilious, but being generally of a greenish and occasion- ally of a bluish tinge. The greenish fluid annoyed him much from its extreme bitterness, and the quantity thrown up in the course of a day varied from three to four quarts of fluid. He complained also of pain, referred to the stomach or lower part of the chest, which continued throughout the attack, being most acute at its commencement; for the last year, this sensation had passed into a feeling of painful constriction, which he described as a “con- tracted feeling of his inside,” and compared it to something like the effects of a cord drawn tightly, so as to compress or strangulate his body exactly along the outline occupied by the insertions of the diaphragm. During the prevalence of the attack, he had profuse perspirations, particularly towards the termination of each paroxysm. The duration of the first attack did not exceed four or five day«, after which, he became quite well, and continued so for six or seven months, when his symptoms suddenly returned. He began to reject every thing from his stomach as before, but in the course of a few days the vomiting disappeared, and for a considerable interval he had no return of his complaint. In the year 1830, he had three attacks of a similar description ; from these he recovered also completely, and without remarking any diminution of power in his lower extremities. In 1831, however, the disease began to PARAPLEGIA. 87 assume a more serious aspect; the paroxysms became much in- creased in severity, lasted longer, and recurred at shorter intervals. For one of these attacks he took mercury, and was salivated. In 1832, his symptoms became still more violent, and the duration of the paroxysms more protracted. He had one in March, a second in May, and a third in June, each of which was accompanied by some numbness and loss of power in the lower extremities; this, however, was slight, and disappeared altogether as the vomiting subsided. About this time, he noticed that his urine was scanty, and deposited more sediment than usually. He also complained of being very apt to catch cold whenever he got out of bed, and stated that he suffered occasionally from severe twitches and pains in his legs, thighs, arms, and other parts of his body, which were generally succeeded, and carried off, by profuse perspirations. In August, 1832, he had a violent attack, which lasted nearly a month. The vomiting was incessant, continuing night and day, and he suffered severely from the feeling of painful constriction already described. On getting up after this attack, his legs sud- denly failed him, and he dropped down on the floor quite powerless. The paralysis did not now disappear during the intervals, although it grew somewhat better after each fit of vomiting had ceased ; in- deed he used to improve in his walking after the paroxysm had entirely disappeared; and, aided by two sticks, supported himself so as to give some hopes of a recovery, until a recurrence of his attack reduced him again to a state of almost total paraplegia. His legs now began to waste sensibly, and he noticed that they had lost their feeling and were remarkably cold. He also complained of severe twitches of pain in various parts of his body, accom- panied by profuse night sweats, and turbid, scanty urine. For some months before his death he was completely paraplegic, and continued to be attacked with violent fits of vomiting. The vomiting went on night and day, and he was unable to retain the mildest and most soothing substances for a moment on his stomach. Mr. Crampton and Ur. Ireland attended him with me, and we had recourse to every thing we could think of to allay the irritability of his stomach, but in vain. After continuing to resist obstinately every form of treatment for five or six days and nights, the vomit- ing would suddenly cease, the gentleman would exclaim, “Now I am well,’’and he would then eat, with perfect impunity,substances which would prove irritating and indigestible to many stomachs. This was one of the most singular circumstances I ever witnessed. The transition from a state of deadly nausea and obstinate retching to a sharp feeling of hunger, used to occur quite suddenly. One hour he was the most miserable object you could behold, racked with painful constrictions across the epigastrium, alternately flushed or bathed with cold perspiration, and rejecting every thing from his stomach, the next found him eating with a voracious appetite whatever he could lay hold of, and digesting every thing with appa- rent facility. It may be observed that as the disease in this case proceeded, the 88 graves’s clinical lectures. intervals between the attacks became diminished, while the parox- ysms became increased in duration. For the first two years they continued only for four or five days, and appeared at intervals of six or seven months ; latterly they used to last for eight or ten days, and returned every third or fourth week. During the parox- ysm the only thing which he took was a little cold water with some brandy and a few drops of laudanum, which remained longer on his stomach than any thing else, and enabled him to enjoy a few minutes’ sleep. He never complained of any headache, and his intellect was remarkably clear, and his memory good. No trace of organic disease could be detected in the abdominal viscera, and there was not the slightest tenderness over any part of the spine. He also retained to the last a complete power over the bladder and rectum. At length his system began to give way; long confinement to bed, and the frequent recurrence of these exhausting attacks, com- pletely wore him out, and he sank on the 30th September, 1833. A post mortem examination was allowed by his friends, and we scrutinised every part of his system with the most anxious care. The brain, cerebellum, spinal cord, and their investing membranes, were carefully inspected; we examined the large nervous trunks that supply the lower extremities, inspected the viscera of the thorax, and searched for evidences of disease in the stomach and intestinal tube: we could find none. There was no lesion of the brain or spinal cord, no thickening or vascularity of membranes, the large nerves exhibited their normal condition, the stomach was perfectly healthy, the intestinal canal natural, the liver and other glandular viscera of the abdomen without any trace of appreciable derangement. Here, then, was a case of perfect paraplegia, (I say perfect, for he had lost all power of his lower extremities for more than two months before his death) which may be fairly termed functional, inasmuch as there was no lesion of any part of the nervous cen- tres to explain the phenomena present. How then are we to account for them? The first symptoms were undoubtedly those of abdominal irritation, as manifested by the tendeney to diarrhoea in an originally costive habit, accompanied by violent paroxysms of vomiting, which recurred at distant intervals. Are we to attribute this diseased condition of the stomach and bowels, which, from the remarkable periodicity of its occurrence, was evidently functional, to irritation, congestion, or inflammation of the brain or spinal marrow? From the data we are in possession of, it appears that this question must be answered in the negative. There was no headache, heat of scalp, throbbing of the temporal arteries, or other sign of determination to the head ; or congestion, or inflammation of the brain, either before or during the attacks. The patient’s in- tellect was all throughout remarkably clear, and his memory good. Again, if we look for the origin of the disease in the spinal cord or its investments, we can find nothing to assist in explaining the phenomena. There was no pain in any portion of the spinal cord, PARAPLEGIA. 89 and at no period of his illness could we detect any tenderness over the spinous processes. The history of the case seems to prove that whatever was the cause which operated on the nerves of the stomach and intestines, it gradually extended the sphere of its morbid influence to the spinal cord, and, through it, implicated the nerves of the lower extremities. The case is in many respects highly interesting, and well worthy of the attention of the patho- logical enquirer. The dissection was conducted, in the presence of Dr. Ireland and myself, by my friend and former pupil, Mr. Harris, so advantageously known for his skill in morbid anatomy. It was not made in a hurried or careless manner, each organ was carefully examined, and the process occupied at least four hours. The next case to which I shall call your attention is one which I have already given in a former lecture: it seems, however, to be so similar in the nature of its exciting cause to the foregoing, though differing in some of its symptoms, that I shall beg leave to repeat it here. James Moore, aged 32, was admitted into the Meath Hospital on the third of March, 1833, under Dr. Stokes’s care, for an attack of paraplegia, which he attributed to cold and wet feet while engaged in working in a quarry. About a month before admission he per- ceived a stiffness of the great toe of his right foot, afterwards numb- ness and coldness of the sole, and then of the leg as far as the knee, and dragging of the limb in walking. During the progres- sion of the disease up along the thigh it commenced in the left foot, and, after a few days, he experienced almost complete paralysis of sensation in the right lower extremity, and a lesser degree in the left, accompanied by so much diminution of the power of motion, as to render him unable to walk without support. About three weeks after the appearance of paralysis in the lower extremities, the little finger of the right hand was attacked with numbness, which passed successively to the rest, attended by some loss of the sense of touch and power of grasping objects. He had also reten- tion of urine, and the bowels were obstinately constipated. There was no tenderness over any part of the spine. He had no pain in the head ; his pupils were natural; pulse, sleep, and appetite also natural. Here we have an instance of paraplegia apparently originating from an impression made on the nerves of the lower extremities. The man had been engaged in draining a quarry, and during his occupation was constantly exposed to wet; shortly after this he begins to complain of numbness and loss of power in the right lower extremity, and, during the progression of the disease up along the limb, the left becomes similarly engaged. About three weeks afterwards, the hands, which had been also, but not so fre- quently, exposed to the influence of cold and wet, begin to be affected with numbness, and the power of grasping objects becomes diminished. To what can we attribute these symptoms, except to the influence of cold acting on the nervous filaments of the cutaneous surface of the limbs, extending its morbid impression to 90 graves’s clinical lectures. the spine, and thence reacting on the nerves, so as to produce im- pairment of the power of motion and diminished sensation ? The man certainly had no symptom of cerebral or spinal disease, nor was there any thing connected with the state of the nervous cen- tres which would lead to the supposition that paraplegia was the result of an irritation originally affecting the brain or spinal cord. It was on these grounds that I gave it as my opinion at the time, that the disease was an example of creeping paralysis, having its origin in an affection of the peripheral extremities of the nerves. The next case is one which was also under treatment in the Meath Hospital during the course of last winter : for the particulars I am indebted to my collegue, Ur. William Stokes. A robust, middle-aged man was admitted into the chronic ward of the Meath Hospital, in the latter end of February, 1834, labour- ing under paraplegia. He stated that he was generally employed as a boatman about the river and port, was frequently exposed to cold and wet, particularly in his lower extremities, and that He was in the habit of drinking freely. He had enjoyed good health until about seven weeks before admission, when he was seized with numbness of the feet and legs, which, after continuing for three or four days, was followed by tingling pains running along the course of the nerves. He then remarked that the power of his lower ex- tremities became much diminished, and this gradually increased so as to prevent him from walking or even standing without support. His bowels became obstinately costive, and about a month after the commencement of his attack, he perceived that his urine was dis- charged in smaller quantity than usual, and that he was much more frequently called on to pass it than before. He also men- tioned that he had gonorrhoea about six months before, and that he had used balsam copaiba and injections. Some time after this he said he noticed some white matter passing with the urine, but did not pay any particular attention to it as it gave him no inconvenience. His appetite was tolerably good, and he had no headache or any symptom of determination of blood to the brain. He denied having received any injury of the back, and there was no tenderness over the spinous processes of the vertebras. He had no pain in the spine, either before or since the occurrence of his illness, nor was there any symptom of inflammation of the substance or membranes of the spinal cord. When admitted, he had considerable diminution of sensation and complete loss of motion in one of the lower extremi- ties ; in the other he still retained some power. He had also reten- tion of urine, requiring the daily use of the catheter. The treatment was as follows :—He was placed on one of Dr. Arnott’s hydrostatic beds, as there was a great tendency to stripping over the hips and sacrum, a purgative pill was administered two or three times a day to remove the costiveness, and he was ordered to be cupped over the loins. The latter was done in consequence of his complaining of some tenderness on pressure in the situation of the kidneys. His symptoms, however, went on without any im- provement, and he died about a month after his admission. PARAPLEGIA. 91 On dissection the following phenomena were observed. The kidneys (which were first examined) appeared rather soft, and of a yellowish colour, blit there was no vascularity, suppuration, or other change of structure. The ureters were somewhat distended, but presented no other trace of disease. The bladder was contract- ed, its muscular coat thickened, and its mucous membrane very vascular. There was no affection of the prostate. On examining the spinal cord, Dr. Stokes observed that he thought the cauda equina appeared to be slightly softened, but remarked that from its appearance he could not state that it was actually diseased. The rest of the spinal cord appeared healthy and normal; there was no vascularity, effusion, or softening. External to the sheath of the cord there was a small, flattened, oval body, about the size of half a very small hazelnut, and of a consistence intermediate between lymph and fat. Around this there was some slight degree of vas- cularity. Dr. Stokes observed, that from the small size of this body, and the peculiarity of its texture, he entertained strong doubts as to its having any influence in the production of the symptoms noticed during life. He remarked, although it might have been originally the product of inflammation, and have existed in the form of an effusion of lymph, still the circumstance of its conversion into a fatty substance proved that it must have existed for a very con- siderable time, and the smallness of its size, as well as the obscurity of its origin, did not by any means satisfactorily explain the occur- rence of paraplegic symptoms. The next case which I have to lay before you, appears to be ana- logous in its mode of origin to the former:—“A gentleman of strong constitution, and extremely fond of field sports, particularly fishing and shooting, exposed himself repeatedly to wet feet at a time when he was labouring under the effects of a long mercurial course. Taking large quantities of blue pill, and exposing the lower ex- tremities to wet at the same time, are circumstances which have an obvious tendency to produce disease, and it is not to be wondered if this gentleman became the victim of his want of caution. He got numbness and weakness in his legs, which he at first attributed to fatigue and over exertion ; but as the disease went on, he became more and more powerless, and, finally, applied to me respecting his illness. On examination I found that he had no pain in the back, or tenderness on pressure; nothing, in fact, to indicate any original affection of the spinal cord. The functions of the brain also were natural, and there was nothing about him to lead me to suspect cerebral disease. He had, however, considerable impair- ment of the muscular functions of the lower extremities, and could not walk without the aid of crutches, or some person to support him. In treating this case, I looked upon it as an instance of imperfect paraplegia, in which the paralysis apparently rose from impressions made upon the sentient extremities of the nerves of the legs and feet, at a time when these nerves were particularly liable to be deranged in their functions from the previous use of mercury. | therefore had recourse to remedies directly applied to the extremi- 92 Graves’s CLINICAL LECTURES. ties of those nerves, and fortunately succeeded in restoring this gentleman to the use of his limbs. The cure, however, was not perfect, for a very notable degree of weakness still remains. Of this form of paraplegia I have now witnessed many instances. In most cases I was induced to think that it arose from impressions made by cold and wet on the lower extremities. It is most com- monly observed in young gentlemen who are addicted to fishing and shooting, and who in pursuit of their amusements get wet feet repeatedly, from walking over boggy grounds, or wading in the water. It is also observed in labourers whose employment obliges them to stand in water for many hours together, as in draining, pump-sinking, and other similar occupations. In all cases it as- sumes the creeping form, and generally appears at first in one limb, and afterwards in the other. There is, however, considerable va- riety in the rate of its progress ; in some cases the patients become almost completely paraplegic in a few weeks from the commence- ment of the disease, in others it will go on for months, and even years, before the power of the lower extremities is completely de- stroyed. Where its progress is slow, it makes its approach in an insidious manner, and is at first scarcely noticed by the patient. Its latency is here further favoured by the absence of pain, numbness, or formication ; for it is only at the more advanced stages of such cases that derangement or diminution of sensation is noticed. It is only when making some unusual exertion, as in going up stairs or ascending a hill, that the patient finds a more than ordinary degree of weakness in the lower extremities. The first symptom which generally attracts his attention is an incapability of walking as far as he has been accustomed, but this is attributed to some temporary weakness, or is considered to be the result of previous fatigue. As the disease progresses, walking up an ascent becomes a matter of some difficulty, there is a shuffling motion of the legs, and the pa- tient is apt to stumble from slight obstructions. Gradually the loss of power becomes more manifest, it excites the attention and sur- prise of the patient, and he finds that he is no longer able to walk without the aid of a stick or some person to lean on. The paralysis is, however, seldom complete ; with the help of crutches the patient continues to hobble about, and it is only in bad cases, and at an advanced period of the disease, that he becomes completely para- plegic. The paralysis is never so sudden nor so complete in this form of paraplegia, as it is in cases of disease of the spinal cord, or scrofulous ulceration of the bones and ligaments. In other cases, however, the paraplegia, though evidently of the same origin, and having the same creeping character, advances with much more rapidity ; and the patient may, in a few weeks from the commencement of the attack, experience a very considerable diminution of power in the lower extremities. In such cases it will be generally found that one limb is much more affected than the other, the loss of power being most complete in the limb which was first engaged. With respect to sensation, it appears to be affected as well as PARAPLEGIA. 93 motion. In the slow and chronic form of this species of paraplegia, it does not attract the attention of the patient so quickly as the derangement of muscular power: it is generally some time before he notices any diminution of sensation, and then accidentally. In the more advanced stage, however, this becomes manifest, and is accompanied by a sensation of cold in the lower limbs, which sel- dom extends higher than the knees. In the more rapid and acute form, the derangement of sensation is much more obvious, and is generally the first symptom noticed by the patient. There is at first a feeling of numbness, which commences in the toes or feet, and extends up the limb : this, in the course of a few days, is fol- lowed by formication and tingling pains in the course of the nerves, and then loss of power and diminished sensation. There is, how- ever, in both these forms of paraplegia, much less impairment of sensation than of motion, and the loss of sensation is never so com- plete as in paraplegia from disease of the spine. There is one curious symptom occasionally observed in this dis- ease, which is that, before the appearance of any decided symptoms of loss of power in the lower extremity, irritation of the lower part of the digestive tube takes place; the rectum becomes morbidly excited ; the patient complains of tenesmus, and thinks he is about having an attack of piles. This was the first symptom observed in one of the cases I attended; the patient complained so much that we were induced to examine the state of the rectum, but could not find any thing to account for the morbid excitement. The same observations apply to the bladder, with this exception, that the morbid irritability of this organ occurs occasionally after the disease is confirmed and has made considerable progress. On the whole, however, affections of the bladder and rectum are rare in this form of paraplegia ; and it is only at the advanced stages that we sometimes meet with that derangement in the motor powers of the bladder and rectum, which occurs so frequently, and at such an early period, in the paraplegia from spinal disease. In cases of paraplegia from disease of the spinal cord or its investments, it has been observed that the urine becomes altered in its quality, and assumes an ammoniacal odour. I have not observed this occurrence in the forms of paraplegia that I have detailed. The urine is turbid, scanty, and voided oftener than usual; but I cannot say that I have seen it in any case decidedly ammoniacal, even in the advanced stages of the disease, and where the patient was com- pletely bed-ridden. Should future observations prove that this diagnostic mark is constant, it may be of some value in distinguish- ing this from other forms of paraplegia. In these cases there is scarcely any thing which would lead us to fix on the spine as the seat and origin of the disease; neither can we find any thing in the brain with which we can connect the paraplegic symptoms. There is no pain of the head or spine, very seldom any tenderness, the patients are in the full vigour of intel- lect, and all the organs of sense in their normal condition. The functions of respiration and circulation are unaffected; and it was 94 graves’s clinical lectures. remarked in the first case which I have detailed, that there was no change in the pulse, either during the fits of vomiting, or the inter- vals of ease. The appetite also is generally good ; but, in almost every instance I have met with, there has been remarkably obsti- nate constipation. With respect to the prognosis and treatment of this form of para- plegia, I have but little to say. The prognosis is generally unfa- vourable, particularly where the disease has lasted for some time, and is accompanied by morbid irritation, or loss of power in the bladder or rectum. It is also bad in proportion to the slowness with which it has come on, and the absence of pain or formication of the lower extremities. With respect to treatment, I may observe that I have never seen any benefit derived from applications to the spine. The application of blisters or issues over the back or loins, does not appear to be productive of the least good effect; of the latter, I can speak positively from experience. They are an en- during source of annoyance to the patient, and never produce the least amelioration of symptoms. I am in the habit of applying my local remedies to the legs and thighs, selecting those parts in which the greatest cutaneous sensibility exists, What I generally do, is to keep up a succession of blisters along the inside of the legs, and over the anterior and inner parts of the thighs. The practice of medicine furnishes many proofs of the utility of stimulant applica- tions to the nervous branches, in case of disease affecting the larger trunks. Thus, in sciatica, a blister applied over the ham or calf of the leg, where many of the ultimate ramifications of that nerve are superficial, will frequently produce a much more decided effect than when applied over the origin of the nerve itself. Liniments of a stimulating kind, and blisters repeatedly applied, are the local means on which I chiefly rely in the treatment of this form of para- plegia. After some time, I commence with the use of strychnine, and continue it until some sensible effect on the system is produced, when I omit its further use, and have recourse to the exhibition of sulphur. These are the two internal remedies from which I have derived most benefit. I have in such cases seen very good effects from a perseverance in the use of the sulphur electuary, of which I have given a formula in one of my published lectures. Much also will be accomplished by the external use of sulphur, in the form of baths, and hence cases of paraplegia of this kind might be mate- rially benefited by the internal and external use of the waters of Lucan, Harrogate, Baden, Barege, &c. With respect to the use of mercury, it appears to be decidedly injurious. I have seen it given in three cases; in all it did much more harm than good. This is all I have to say at present on the subject of paraplegia. I fear much that many omissions, and considerable deficiency of materials, will be observed in the statements I have laid before you, I hope, on some future occasion, to be able to communicate a more minute and better digested series of observations on this obscure form of disease. The subject, however, is in itself so interesting, and so important, that I have been tempted to bring it before you, PERITONITIS AND ENTERITIS. 95 perhaps prematurely. My anxiety to excite discussion, and attract further attention to a department of practical medicine hitherto quite neglected, must on this occasion plead my excuse. LECTURE IX. Case of peritonitis and enteritis terminating- in fatal convulsions—Enormous accumu- lation of lumbrici in the bowels, producing death by convulsions—Causes of catarrhal affections of the bronchial tubes—On the rd,les produced by bronchitis—Remarkable proportion between the frequency of the pulse and the respiration—Use of emetics and chalybeates in chronic bronchitis—Symptoms which contra-indicate chalybeates —Trismus from inflammation of the temporal muscles—Pain in the nerves of the face, simulating tic douloureux, and caused by a carious tooth—Case of jaundice, with remarks—Connection between arthritis, jaundice, and urticaria—Analogous series of affections often caused by eating fish. Let me direct your attention for a few moments to a case which presents some interest, as connected with the obscurity of its nature; I allude to that of the young woman. Moran, who died this morning. She came in, on Monday week last, with symptoms of ordinary con- tinued fever, for which the only remedies employed were effer- vescing draughts, diluents, and a proper attention with regard to diet. She had some headache, which went away a few days after her admission; and, as she made no other complaint, her case was looked upon as one of simple fever. Some time afterwards, it was observed that her abdomen was tympanitic, and that she had diarrhoea; but she persisted in denying that she had any abdominal pain or tenderness. In addition to this, symptoms of bronchial in- flammation set in, but without any remarkable distress of respira- tion, or acceleration of pulse. She made no complaint whatever, and seemed extremely unwilling to communicate any information respecting her condition. Under these circumstances, all that could be done was to treat the symptoms as they became manifest, and, accordingly, after having leeched the belly, I ordered a large blister to be applied so as to cover the epigastrium and lower part of the chest anteriorly. The only thing remarkable in her case, and to which I should have called your attention more particularly, was the repeated occurrence of rigors. It appeared, from the account given by the nurse, that she had frequent attacks of shivering on last Friday, and the two preceding days ; and I have already told you, that where this occurs, you should always suspect the exist- ence of some local inflammation. Such were the principal phenomena observed in this case. On Saturday, she stated that she felt better after the application of leeches, and had no pain or tenderness whatever in the belly; but still it was observed that the tympanitis was undiminished, and that she was not by any means improving. This morning she called to the nurse to assist her in getting to the night-chair, when, after a 96 graves’s clinical lectures. few minutes, she was suddenly seized with a violent convulsive fit, and expired. I may observe, that there was nothing in this case which would lead one to suspect the existence of cerebral inflammation. The fever was of the ordinary kind ; there was no remarkable accelera- tion of pulse (the number of beats in the minute being only 84 when we examined her on Saturday); she had some headache, but this did not continue; and there was no flushing of the face, redness or suffusion of the eyes, heat of scalp, or throbbing of the temporal arteries. There was nothing to inform us that disease was going on in the brain, and yet the patient dies violently convulsed. Under these circumstances, how are we to explain the manner of her death ? At present, I believe it would be better not to enter on any enquiry respecting this point. I shall endeavour to procure an examination of the body, and, until then, shall make no further ob- servation. On opening the body the next day, no trace of disease could be found in the brain. The thoracic viscera were also healthy, with the exception of some vascularity and congestion of the bronchial mucous membrane. In the abdomen there were ample marks of extensive inflammation. The cavity of the peritoneum contained a quantity of serous fluid; the intestines were glued together by lymph at almost every point of contact; and the serous membrane was highly vascular. The mucous membrane of the intestines was extensively inflamed, and there were numerous small ulcers in the situation of the glands of Peyer. The uterus, with its append- ages, was in a state of intense inflammation, and presented marks of recent delivery. It appeared afterwards, that she had been delivered of a male infant, the fruit of an illicit intercourse, a few days before her admission into the hospital. Under the influence of shame, and a desire to conceal her condition, she had, through- out her illness, persisted in strongly denying the existence of any abdominal symptoms whatever. Here this question,—whether the disease might have been cured had its true nature been discovered on her admission,—naturally suggests itself. I must candidly confess that I think it might; and I regret extremely that the peculiar circumstances of the case ren- dered her anxious to conceal the existence of the symptoms of abdominal inflammation ; for had it been otherwise, a more active antiphlogistic and mercurial treatment might, perhaps, have been successfully applied. This case affords another example of the truth of what I endea- voured to establish in a former lecture, concerning the effects which irritations of the periphery are capable of producing on the central portions of the nervous system; for here death was induced by con- vulsions, the mediate cause of which was situated not in the brain but in the abdomen. A very remarkable and striking case of a somewhat similar nature, has been lately published by Dr. Eber- maier, in Rust's Magazine (Vol. 42, Part I., p. 52, et seq.), in which the abdominal irritation, caused by an enormous collection BRONCHITIS. 97 of lumbrici in the small intestines, occasioned, in a child who had previously enjoyed good health, a sudden attack of pain in the belly, and vomiting terminating speedily in fatal convulsions. The intestines were not inflamed, but were completely obstructed, in many parts of the ileum, by successive round masses, formed by agglomerations of lumbrici, rolled up together, and enveloped in an adhesive paste formed of half-digested bread, cemented by a tena- cious mucus. The worms were too numerous to count, amounting to many hundreds. A man named Murray, of middle age and rather strong constitu- tion, has been recently admitted into the small chronic ward, with bronchitis of long standing, and frequent exacerbations. It is a case in which I am afraid a permanent cure is out of the question, and so far it is unsatisfactory; still it is necessary to be acquainted with such cases, for it is a matter of some importance to be able to inform a patient whether his disease is curable or not, and how far it admits of being relieved by treatment. Bronchitis is an affection which generally arises from impressions made by cold, either on the skin or on the mucous membrane of the lung. I think it extremely probable that, when a person gets a catarrhal affection from exposure to cold, it is not always in conse- quence of an impression made on some part of the cutaneous sur- face. Indeed, it appears reasonable to believe that an attack of bronchial inflammation may be equally the result of an impression made directly on the mucous lining of the lung; and that a person exposed to sudden change of temperature, as in passing from a heated room into the cold air, may get inflammation of the mucous membrane of the bronchial tubes, for the same reasons that, under similar circumstances, inflammation may be generated in the mu- cous membrane of the eye, giving rise to conjunctivitis. We know well that one of the most common causes of inflammation of the conjunctiva, is the sudden exposure of the eye to cold sharp air, after it has been for some time submitted to the relaxing influences of strong heat and light; and there is no reason why the same rapid change of temperature, under similar predisposing causes, should not originate disease in the mucous membrane of the bronchial tubes. It is true, indeed, that nature has taken especial pains to maintain an equable temperature in the air admitted into the chest at each respiration; the passage of this air through the mouth, nose, and pharynx, where it is warmed by the contact of an extensive mucous surface, and the small proportion which it bears to the residual air remaining in the lungs after an ordinary expiration, are circumstances that must powerfully counteract the low tempe- rature of air inspired in very cold weather. Still a considerable difference of temperature must exist between the inspired and ex- pired air, and consequently the air passages are exposed, more than any other tissue of the body, to successive and rapid alternations, which never cease from infancy to old age. Nature has, of course, wisely accommodated the vitality of the bronchial mucous mem- brane to the circumstances in which it is placed, and the force of a 98 GRAVES’S CLINICAL LECTURES. never-ceasing habit still further enables it to sustain rapid vicissi- tudes of temperature with impunity. In this it is probably equaled by the surface of the eyeball, which, alternately covered, warmed, and moistened by the eyelids during the act of winking, and ex- posed to the cold of the air, increased by a rapid evaporation from its own surface while the eye is open, must, indeed, undergo rapid variations of temperature, and yet it is never frost-bitten. When inflammation has fastened on the mucous membrane of the air passages, it makes a vast difference as to the part on which it fixes. The air passages commence with the larynx, and termi- nate with the ultimate ramifications of the bronchial tubes. If the disease settles at the entrance of the air passages, and forms laryn- gitis, the case becomes a very serious one, laryngitis being in the infant, and sometimes also in the adult, attended with dangerous and even fatal symptoms. If the trachea should happen to be the part on which the disease falls, the inconvenience and suffering are also considerable, but the danger is by no means so urgent as in the former case. The same thing may be said of the larger bronchial tubes; inflammation here is rarely attended with such violent symptoms as those which characterise laryngitis, and it is much more amenable to treatment. Out when inflammation attacks the minute bronchial tubes to any considerable extent, and particularly if it happens to be general—that is, if it affects the bronchial tubes in every part of the lungs—we have just grounds for alarm ; the disease is one of an intense character, and, unless quickly relieved, runs on to a fatal termination with great rapidity. You perceive, then, that if a patient catches cold, and gets an attack on the chest, it is of great importance to be able to ascertain what the situation and extent of the disease are, and whether the minute bronchial tubes are engaged or not. Now, how do you know this? Simply thus:—You first make a cursory examination of the whole chest, by applying the stethoscope over the superior, middle, and inferior portion of each lung, both before and behind; and, if you every where hear something, you conclude that the bronchitis is general, and not confined to any particular part. You next proceed to examine with greater attention these wheezing sounds; you apply the stethoscope, and if you find in each sepa- rate spot many sources of diseased sound—if you hear a ivheezing from a great many points close together—you may be sure that the morbid sound proceeds from inflammation of the minute tubes, for the larger ones cannot exist in the small spots over which you apply the stethoscope in such numbers as to give rise to so remark- able a plurality of sounds. Of this you may be certain, that, when you find a great many sounds are audible over a small space, the minute bronchial ramifications are engaged. It is the custom, with those who lecture on auscultation, to enu- merate many sounds as connected with alterations in the condition of the bronchial tubes. We hear of the mucous, the sonorous, and the sibilant ronchus—their varieties and intermixtures. Now I know, by experience, that these names are very apt to confuse and SOUNDS HEARD IN THE CHEST. 99 perplex the young; stethoscopist. There is no necessity for studying with great attention the definitions of these words, or the descrip- tions of the various sounds they are meant to represent: I am always anxious to avoid loading the memory of the student with names. With regard to the rales in bronchitis, all he need bear in mind is, that the nature of the sound produced by air passing through the bronchial tubes will be modified accordingly as these tubes are large or small, are dry or moist, or as the moisture they contain is thin or not. The two things of greatest importance in examining a case of bronchitis is to ascertain whether the minute bronchial ramifications are engaged, and, if the tubes contain any moisture, whether it is thin or viscid. I seldom, therefore, confuse the student by telling him whether the rifle is sibilant or sonorous, when asked about the nature of the sounds heard in a case of bronchial inflammation. All I say in reply is this: that the sounds are produced by the large or small bronchial tubes, and that they are either moist or dry. When the large bronchi alone are inflamed, the sounds issuing from the lung subjacent to the stethoscope are comparatively few in number, sel- dom exceeding two or three; they are likewise, when dry, of a grave tone, resembling the prolonged note of a violoncello, or the cooing of a dove; or, when moist, the bubbles are large, scattered, uneven. When the minute tubes are engaged, we hear, on the contrary, not a few, but many sounds, evidently proceeding from a small portion of lung; three, four, or even six or seven sounds may be perceived together, or circumscribed within very narrow limits. These sounds undergo rapid changes of tone during the same respiration, while every moment some of them appear to cease, to be replaced by new ones. The wheezing they produce is, when dry, sharp; but observe, it is very unusual to find every one of them dry : when dry sounds occur, they are generally accompanied by others, equally minute, but evidently moist. The moment I find, on applying the stethoscope, that a great many sounds are heard over a small spot, and that these sounds are dry and sharp, or are accompanied by certain modifications denoting the passage of air through fluid, I call the disease inflammation of the minute bronchial tubes, with increased secretion obstructing the free en- trance of air. An attention to these considerations is of great importance in ascertaining the nature of acute or chronic bron- chitis; for the danger is not only proportioned to the extent of the disease, but also the circumstance of the minute tubes being engaged, and the quantity of fluid they contain. The sound shows that not only the minute tubes are diseased, but also that there is a consider- able quantity of viscid fluid in them, preventing the entrance of air into the air cells, and tending to produce asphyxia. In the case we are at present considering, we found, on examin- ing the chest, that the minute bronchial tubes were extensively engaged, and they were obstructed by a copious secretion of mucus producing considerable dyspnoea. We found, however, that this condition had lasted for many months, and that the disease was 100 graves’s clinical lectures. essentially chronic. He had no fever; his skin was cool; his tongue moist; appetite and digestion good ; and his pulse, which had been only 60 on his admission, sank to 46 after he had been in bed for some days. Such extreme slowness of pulse as this is a very re- markable circumstance, particularly in cases of pulmonary disease : it is seldom met with except in cases of cerebral affections. Here was a man breathing twenty-six times in a minute, and with a pulse at 46; whereas, if the pulse was proportioned to the respira- tion, it would have been much quicker. The relation of the num- ber of respirations to the beats of the artery at the wrist should be as one to four; thus, when we breathe fifteen times in a minute, the pulse should be at 60. But here we find a man breathing twenty-six times in a minute, and yet his pulse is only 46. We had another instance like this, in a patient in the chronic ward, whose pulse was 60, while his respirations were thirty-six in a minute. It seldom happens, when pulmonary disease is in the acute form, and respiration considerably accelerated, that there is not a corresponding increase in the frequency of the pulse ; but, in chronic cases of this description, the system becomes gradually accustomed to the derangement; the continued acceleration of breathing ceases to affect the action of the heart; the lung, which is obstructed by disease in the performance of its functions, con- trives, by working more frequently, to aerate the requisite quantity of blood, and, the heart adapting itself to the change of circum- stances, the pulse returns gradually to the natural standard. I have seen many cases of phthisis, in which there was accelerated breathing, with slow pulse, but these were always cases of a chronic kind. I have never observed the same phenomena co-existing when the disease was acute; it is a state of things which is compatible only with chronicity of disease, in which the system becomes gradually accustomed to the change, and a kind of artificial equi- librium is finally established. In this case we find that a man of tolerably good constitution, after exposure to cold, gets an attack of bronchitis, which becomes chronic and extends almost over the whole lung. He has a cous;h always existing—sometimes better, sometimes worse, occasionally aggravated. This cough is accompanied by a copious secretion of mucus; and this state of things continues for more than twelve months. Now, when bronchitis has lasted so long on persons of his class in life, it is very difficult to be cured ; his poverty, his want of proper clothing, his liability to the ordinary exciting causes of bronchitis from the nature of his employment, and the habitual disregard of self so constantly observed in persons of this descrip- tion, are all circumstances which forbid us to entertain any hopes of giving permanent relief. There are two points to be attended to in the treatment of this and every other case of chronic bronchitis: first, whether there be any recent attack, and consequently any fever and exacerbation of the local symptoms present; and, in the next place, whether the secretion from the bronchial mucous membrane be copious or EMETICS AND CH AL VBEATES IN BRONCHITIS. 101 scanty. Now, at the period of this man’s admission, there was some slight excitement of the pulse, but there was no fever or in- crease of bronchial inflammation present, and the heart’s action was apparently not influenced by the state of the lung. In addition to this, there was no urgent dyspnoea, and the secretion from the lungs was extremely abundant. We therefore commenced by ad- ministering an emetic, which was repeated for two or three days, and then prescribed the following mixture: mist, ferri composita, 3 ij ; tinct. scillae, tinct. hyoscyami, aa gj ; to be taken three times a day in an ounce of almond emulsion. In chronic bronchitis, where no fever, no remarkable dyspnoea or acceleration of the pulse is present, and where the bronchial secretion is very copious, you will be able to produce very good effects by giving an emetic every night for two or three nights, before you begin with remedies calculated to arrest the supersecretion from the lung. They are productive of a double advantage in such cases: a large quantity of mucus is discharged from the stomach and lungs, expectoration is rendered more easy, the tongue cleans, and the appetite is im- proved. It was on this account we gave them in the present case, and, as you may have perceived, with much benefit. In no disease are we more apt to have a foul, loaded, and furred tongue, than in bronchitis. This state of the tongue, being usually accompanied by loss of appetite and indigestion, is frequently attributed to a bad stomach. Now the truth is, that in such cases the state of the tongue and the state of the stomach are both produced by one and the same cause—viz., the unnatural state of the bronchial mucous membrane. In the latter tissue the train of morbid actions com- menced, and from it was derived that source of irritation which, inducing disease in the bronchial mucous membrane, caused a state of parts rapidly propagated along that membrane to the mouth and tongue on the one hand, and to the stomach on the other. We afterwards had recourse to a tonic and astringent chalybeate—the mist, ferri comp.—with the view of improving the general system, and checking the superabundant secretion from the bronchial tubes. The action of a chalybeate is not merely limited to strengthening the tone of the stomach and general system ; it is also well calcu- lated to arrest the superabundant secretion from mucous surfaces in many chronic fluxes, and hence its utility in gleet, diarrhoea, and chronic bronchitis. We gave the compound iron mixture in prefer- ence to a simple chalybeate, because the other ingredients—namely, myrrh and sub-carbonate of potash—have a tendency to produce the same effect. I do not, however, prescribe this medicine in such large doses as I have frequently seen ordered, and I never give it alone. I order a dram or two to be taken three times a day, and I dilute this quantity by adding to it half an ounce or an ounce of almond emulsion or mint water. In this form it is a much safer remedy in the treatment of fluxes depending on chronic inflamma- tion, and its exhibition is much less likely to be followed by sinister accidents. I have, in the present instance, combined with it a small quantity of squill ; the reason of making this addition is so obvious 102 GRAVES’s CLINICAL LECTURES. that it is unnecessary for me to do more than notice this fact. I have also added some tincture of hyoscyamus, which is an ex- tremely valuable sedative in the treatment of many forms of pulmo- nary disease. However well planned this treatment seemed to be, it did not succeed. After taking the mixture for a day or two, the man began to complain of tightness across his chest, and we were obliged to give it up. I have already stated, that in cases of this description, where the patient is using remedies to arrest secretion, you should be cautious in administering them at first, and attend carefully to their effects. If, after a patient has been using a chalybeate, or any remedy administered for similar purposes, you find that constric- tion of the chest and dyspnoea is increased, no matter whether the secretion is diminished or not, you may be sure that you are doing more harm than good. When the remedy acts favourably, you may know it by the following signs :—respiration becomes less frequent, and is performed with less distress, the expectoration be- comes more free, the sputa begin to assume the globular form, its quantity is diminished, and it is less tenacious and viscid in its consistence. When you give a stimulant, therefore, in chronic bronchitis, you must watch its effects with care, and if it produces any increase in the difficulty of respiration, or any pain or tightness of chest, you must omit it altogether, and pass to an expectorant of a less irritating character. In this case we stopped the use of the mistura ferri composita, and immediately ordered the patient to take a grain of tartar emetic in a pint of whey. This simple remedy succeeded in a very remarkable manner, producing on the first day a very considerable alleviation of symptoms. A man was admitted into the chronic ward a few days ago who cannot separate the lower from the upper jaw to the distance of more than two lines. What are the cases in which we find this immobility of the lower jaw? Most commonly in tetanus or locked- jaw ; but here this cannot be the case, for the man has no sign indicative of a tetanic affection, no rigidity of the muscles of the neck ; his countenance is very different from that of a tetanic pa- tient, and he has not been exposed to any of the ordinary exciting causes of that disease. But leaving all consideration of the nature of the disease out of the question, what is it that prevents him from moving his lower jaw ? It must depend on one of two causes; either the muscles which perform the motions of the lower jaw are stiff, rigid, and incapable of motion, or else there is some disease of the articulation which obstructs the motion of the bone. This pro- position is universally true of all articulations, that when they become impeded or completely obstructed in their motions, the derangement arises from some abnormal condition of the muscles, or of the bones and ligaments which form the joint. In this case we find, that, in addition to being unable to perform the proper motions of the lower jaw, the patient has intense pain, darting from the angle of the jaw towards the temple, the ear, and the side of the neck. This pain is of an extremely violent cha- CASES SIMULATING TIC DOULOUREUX. 103 racter, so as to resemble tic douloureux, and the resemblance is still farther increased by its being more or less intermittent. Now, on enquiry into the history of this case, we find that the patient had some time ago laboured under toothache, for which he got the last molar tooth but one of the upper jaw extracted, and that immedi- -ately afterwards he was seized with violent pain in the part, and found that he could no longer move his lower jaw as usual. I have seen many cases of this kind, in which a painful or carious tooth, or an injury done to the gum or jaw, has been followed by violent darting pain in the nerves of the face, simulating in many particulars tic douloureux. I remember being sent for to Middle- ton, near Cork, some time since, to see a young lady of delicate constitution, whose health was materially deranged from what was said to be an attack of tic douloureux. She had been under the care of many practitioners, and had used very large doses of the carbonate of iron and sulphate of quinine, and at the time I visited her was taking arsenic. The first thing I did on my arrival was to examine her teeth. On close inspection I observed that on the crown of one of the upper molar teeth there was a spot which ap- peared to be decayed, and found on enquiry that she had frequently suffered from pain in this spot when she drank any cold liquid. I had the tooth drawn and soon afterwards the pain completely ceased. Yet in this case the pain was not only of an intense character, pre- venting sleep and wearing out her strength, but it had its intermis- sions, and was aggravated at particular hours of the day. Another instance of the same kind came under my notice about twelve months ago. A young lady was brought to me by a medical friend of her’s to have my advice for an attack of tic douloureux. She had been attended by this gentleman with great care, and no mode of relief left untried, for her sufferings were intense, and she had constant exacerbations of pain. I asked him, were her teeth sound, or had she any disease of the gum or jaw ? He said not, and that he was sure of this, for he had examined her teeth over and over again. On opening her mouth, however, I thought I saw some appearance of unsoundness in one of her teeth, and recommended her to go to Mr. M’Clean and get it drawn. She did so, and the pain quickly disappeared. I could also give many cases in which an injury done to some of the branches of the dental nerve has given rise to symptoms closely resembling those of the tic doulour- eux. One of the most curious circumstances connected with such cases is, that the pain is always of a more or less intermittent cha- racter. The same thing is observed in that form of headache which arises from irritation of the brain, produced by spiculae of bone growing from the internal table of the skull. In a case which occurred some time back at the Meath Hospital, where several spi- culas, some of them more than a quarter of an inch in length, were pressing on the brain, the headache was of a distinctly intermittent character. This remarkable periodicity of exacerbation, in cases where the operation of the exciting cause continues still the same, seems to be peculiar to the nervous system. 104 graves’s clinical lectures. In many cases considerable derangement of the facial nerves is found to follow an injury done to some branch of the dental nerve in drawing a tooth. When the bone has been injured by the force used in extracting the tooth, it frequently happens that, if the injury be not quickly repaired, and the parts healed up, symptoms resem- bling those of tic douloureux or rheumatic neuralgia will supervene, and give the patient a great deal of annoyance. Such was the ori- gin of the mischief in the case before us; the man received an injury of the upper jaw in drawing a tooth, which is not as yet healed, as you may perceive by introducing a probe between the separated portions of gum, when you will find it grate against the rough sur- face of the bone. In addition to this, there is considerable tenderness of the gum and swelling of the neighbouring parts, which have extended to the muscles, their sheaths, and finally to the articulation of the lower jaw. You can satisfy yourselves of this by examining the parts and striking the lower jaw, so as to press it suddenly up- wards and backwards into the glenoid cavity, just in the same way as you press the thigh bone against the acetabulum when you wish to ascertain whether there is inflammation of the hip joint. The motion of the lower jaw is here prevented by inflammation, ex- tending from the upper jaw so as to involve its ligaments and the neighbouring muscular sheaths. There are other causes, also, which may be attended with the same diminution of motion in the joint. Thus a man may get an attack of rheumatism in the scalp, which may extend to the temporal muscles and prevent him from being able to depress his lower jaw, and I have known cases in which this condition of the temporal muscle has given rise to sus- picions of the existence of trismus. When you examine the articu- lation you find nothing amiss, but when you come to press on the temporal muscle above the zygoma, the patient complains of pain and tenderness. The irritation produced by rheumatic inflamma- tion gives rise to a fixed rigid state of the muscle, and hence the patient cannot open his mouth. This form of disease I have de- scribed long since, in a paper published in the Dublin Hospital Reports. It can be relieved with great ease by applying leeches to the temple, and ordering the patient to rub over the part a small portion of mercurial ointment with extract of belladonna, two or three times a day. The same state of the temporal muscle is some- times observed as resulting from an extension of inflammation, in case of a wound of the scalp in its vicinity. In the case before us, almost every thing will depend on the process which nature may adopt with respect to the injury of the maxillary bone. If the bone throws up healthy granulations, and the inflammatory process ceases, the affection of the nerves, as well as of the muscles and joint, will quickly subside. All we can do under the circumstances is to apply leeches over the side of the face, and order the man to rub in mercurial ointment; every thing, how- ever, will depend on the turn the disease of the bone may take. I wish to make a few observations on a case of jaundice in the small chronic ward. I do not intend to enter into any particular JAUNDICE WITH ARTHRITIS AND URTICARIA. 105 enquiry concerning the causes of this disease; you are aware that it may depend upon many causes, upon affections of the mind, gastro-duodenitis, inflammation or abscess of the liver, the presence of gall-stones, diseases of the head of the pancreas, aneurism of the hepatic artery, and, what is more remarkable, in some cases may arise without any assignable cause whatever. In the present in- stance it seems to have been the result of acute hepatitis. The man was attacked with symptoms of inflammation of the liver, and about a fortnight afterwards became jaundiced. It is unnecessary for me to draw your attention to the history of the case, or the pre- sent state of the patient; all I shall do at present is to make a few remarks on some points of treatment. In the first place, the jaundice is, as you perceive, of an intense character; the man is as yellow as he could be. Now this I look upon as a favourable sign; the deeper the colour is in recent cases the greater is the chance of effecting a cure. There are no cases so untractable as those in which the tinge of yellowness is so faint that you would be likely to overlook it, as in the case of a man in the chronic ward, in whom the colouring is so slight, that it re- quires some attention to ascertain whether he is jaundiced or not. Such a care as this is always of a chronic, untractable character, and this is too frequently connected with a scirrhous state of the liver. Again, in this man’s case we cannot detect any appearance of bile in the evacuations : this is another good sign. When jaun- dice co-exists with bilious stools, the prognosis is, generally speak- ing, bad. A but slight tinge of yellowness of skin, and the con- tinued presence of bile in the stools, are two circumstances which I always look upon as indicative of an unmanageable and frequently incurable affection. It generally depends on a scirrhous state of the liver, or some organic derangement beyond the power of medi- cal treatment. Again, another good sign in jaundice is, that as long as the bile is absent in the stools it should be present in the urine. If a patient labouring under jaundice has clay-coloured stools, and you find on examination that his urine becomes heavily laden with it, it is a very favourable circumstance, for it shows that, al- though the usual channel for the exit of bile from the system is stopped up, nature has provided a remedy for the evil by establish- ing another emunctory. You can understand then the reason of the anxiety I felt at finding that this patient’s urine was becoming paler and diminishing in quantity, at a time when bile was not present in the stools. In acute cases of jaundice, you should always bear in mind that patients will sometimes have a complete sup- pression of the biliary discharge, followed by coma, without any symptoms of disease of the brain. Why this occurs iti some and not in all cases we cannot understand, but, from whatever cause it may arise, we find that in some instances jaundiced patients become stupid and lethargic, and die in a state of confirmed coma. In such cases there is always very great danger, and where coma has appeared as a prominent symptom of jaundice, you should always give an unfavourable prognosis. I have never seen but one patient 106 graves’s clinical lectures. recover under such circumstances. On the other hand, it is equally curious that derangement of the urinary system is one of the most common symptoms of disease of the brain. You will therefore un- derstand the cause of my alarm, when I observed a diminution of the urinary secretion in this patient. As soon as I perceived this symp- tom, though the patient had been taking mercury, and was improv- ing at the time, I immediately administered a diuretic, and this fortunately succeeded in producing a copious flow of urine. We prescribed the following diuretic, which had not been taken for many hours when it produced a decided determination to the kid- neys :— R. Mistura amygdalarum, 3 viij. Nitrat. potassse, Bij. Tinct. digitalis, gtt. xv. Spiritus setheris nitrosi, 3 ij- of which a tablespoonful was to be taken every second hour. There is one practical remark to be made on this and other simi- lar cases. As soon as the symptoms of jaundice begin to decline, and bile makes its appearance in the stools, you should attend care- fully to the state of the patient, and note any symptom which may occur of an anomalous character. Now, in this patient’s case, we observed that a degree of restlessness was present, which terminated in a complete want of sleep. About the time when he began to manifest a degree of improvement, he became quite sleepless with- out any evident cause, and continued so for two or three nights; and I have already stated in a former lecture that, no matter when this symptom occurs, whether in fever or towards the termination of some acute disease, it always requires your attention. I there- fore immediately took proper steps to restore sleep; and accordingly we find, on enquiring this morning, that he has rested well and feels much better. The man had been taking mercury, and his bowels were free; but, not content with this, I gave him a purgative, consisting of infusion of senna with electuary of scammony. This he was directed to take early in the morning, so as to secure its operation before night; and about nine or ten in the evening, after his bowels had been freely opened, he took a full opiate, which pro- duced a long and refreshing sleep. Before I conclude, allow me to communicate a few detached observations on the connection which exists between jaundice and some other diseases—as, for example, inflammation of the joints. It is now many years since Dr. Cheyne and I attended a gentleman in Lower Mount street, who, in consequence of exposure to cold, was attacked with inflammation of the joints, accompanied by con- siderable general fever; almost every joint was attacked in succes- sion, and his sufferings were excessive. The disease bore the form I have so often described under the name of acute sweating arthritis—a form very obstinate and difficult to treat, and accom- panied after some time with great constitutional debility. When this gentleman had been about ten days confined to bed under treatment, he suddenly became jaundiced, and it was now evident URTICARIA. 107 that acute, but not violent, hepatitis was superadded to the original disease. In a day or two afterwards, a copious eruption of nettle rash— urticaria—appeared over his body and extremities. Exactly the same diseases appeared, and in a similar order of succession, in a man treated in the Meath Hospital, in June, 1832—an occurrence which at. the time excited some interest among the students; for when I observed that jaundice had supervened on arthritis, I men- tioned to the class that it was not at all unlikely that the jaundice would be soon attended by urticaria. I was induced at the time to make this remarkable prediction, as my mind was full of the subject, having been engaged, along with Mr. Porter, in attending a medical friend residing in Bagot street, in whom jaundice was soon followed by urticaria. Since my attention has been drawn to the connection between these three diseases, I have seen and heard of several other instances in which they appeared thus associated together. A circumstance so remarkable deserves to be studied with more than ordinary interest. Let us, therefore, consider what facts are supplied by physiology and pathology capable of throwing some light upon this hitherto unobserved and uncultivated subject. In the first place, nothing has been longer recognised by physicians, as an established fact, than the intimate sympathy which exists, both in health and disease, between the digestive organs and the skin. Now, acute hepatitis always produces more or less derange- ment of the stomach and alimentary canal, and we may therefore consider its connection with urticaria in the same way that we are in the habit of viewing the cases, so frequently observed, in which certain sorts of fish have produced serious symptoms of indigestion followed by nettle rash. The association between these two dis- eases is rendered more remarkable by the fact, that, when fish taken as food exerts a poisonous effect on the system, it frequently pro- duces not merely violent stomach and bowel complaint, but also inflammation of the joints and rheumatic pains. If I can establish this, you will allow that the connection between arthritis, disease of the digestive organs, and urticaria, can no longer be considered as fortuitous and depending on the accidental concurrence of causes having no determinate relation, but must be looked on as owing to and arising from the operation of some fixed law which regulates and originates this development of morbid actions in, if not a fre- quent, at least an uniform mode of succession. The Otaheitan eel (puhhe pirre rowte) produces, when eaten, a most copious scarlet eruption of the skin—most probably urticaria —and occasions sudden tumefaction of the abdomen, together with swelling of the extremities, hands, and feet; the pain felt in the limbs is so excruciating that the patient becomes quite frantic. I may remark here that this, and many other species of fish which act as poisons on the system, give rise very speedily to paralysis of the extremities. You will find, in the Edinburgh Medical and Surgical Journal, vol. iv. p. 396, in an excellent review of Dr. Chisholm’s work on the poison of fish, an account of the effects 108 graves’s clinical lectures. produced by eating the tnurcena conger, the following passage. “ In the course of the following night, they were all seized with violent griping and cholera, together with a peculiar sensation in the lower extremities, attended with violent convulsive twitches, faintings,
