X O deliver a System of the Doctrines and Rules proper for direct- ing the Practice of Physic, is an undertaking that appears to me to be attended with great difficulty ; and after an experience of more than forty years in that practice, as well as after much reading and reflec- tion, it was with great diffidence that I ever entered upon such a work. It was, however, what seemed to be my duty as a Professor that induced me to make the attempt; and Lwas engaged in it by the same sentiments that the illustrious Dr. Boerhaave has expressed in the following passage of the preface to his Institutions : Simtil enim docendo admotus eram sensu, propriorum cogitatorum explicatione do- centem plus prof cere, quam si opus ab alio conscriptum interpretari suscipit. Sua quippe optime intclligit, sua cuiqtte pra cateris placent, wide clarior fere doctrina, atque animata plerumtfite sequitur oratio. §hii vero sensa alterius exponit, infelicius sapenumero eadem assequi- lur ; quumque suo quisque sensu abundat, multa refutanda frequenter invenit, unde graven frustra laborem aggvavat, minusque incitata dictione utitur. It is well known, that a Text-book is not only ex- tremely useful, but necessary to Students who are to hear Lectures ; and from the same considerations that moved Dr. Boerhaave, I also wished to have one for myself; while at the same time, from some pe- culiar circumstances in my situation, I had some additional induce- ments to undertake such a work. Before 1 was established as Professor of the Practice of Physic in this University, I had been employed in giving Clinical Lectures in the Royal Infirmary ; and upon that occasion had delivered, what, in my own opinion, seemed most just with regard to both the nature and the cure of the diseases of which I had occasion to treat. But I soon found, that my doctrines were taken notice of, as new, and peculiar to myself ; and were accordingly severely criticised by those who, ha- ving long before been trained up in the system of Boerhaave, had continued to think that that system neither required any change, nor admitted of any amendment. I found, at the same time, that my doctrines were frequently criticised by persons who either had not been informed of them correctly, or who seemed not to understand them fully ; and therefore, as soon as I was employed to teach a more coniplete system of the Practice of Physic, I judged it necessary to publish a Text-book, not only for the benefit of my hearers, but that I might also have an opportunity of obtaining the opinion of the pub- lic more at large, and thereby be enabled either to vindicate my doc- trines, or be taught to correct them. These were the motives for my attempting the volumes I formerly published ; and now from many- years experience of their utility to my hea&ers, as wel^ as from the fa- vorable reception they have met with from the public, I am induced to give a new edition of t^iis Work, not only, as I hope, more correct in many parts, but also more complete and"comprehensive in Us ge« neiitl extent. S PREFACE. At the first publication of this work, it was intended chiefly fop the use of those gentlemen who attended my lectures ; altho' even then for the reasons I have mentioned, it was rendered more full than text- books commonly are; and, in the repeated editions I have.since had occasion to give, I have been constantly endeavoring to render it more rfull and comprehensive. In these respects, I hope the present edition will appear to be rendered more fit for general use, and better calcu- lated to afford satisfaction to all those who think they may still re- ceive any instruction from reading on this subject. While I thus deliver my work in its now more improved state, with the hopes that it may be of use to others as well as to those who hear my Lectures, I must at the same time observe, that it presents a sys- tem which is in many respects new, and therefore I apprehend it to be not only proper, but necessary, that I should explain he-re upon what grounds, and from what considerations, this has been attempted. In the first place, I apprehend that, in every branch of science with Tespect to which new facts are daily acquired, and these consequently giving occasion to new reflections, which correct the principles for- merly adopted, it is necessary from time to time, to reform and renew the whole system, with all the additions and amendments which it has received and is then capable of. That at present this is requisite with regard to the Science of Medicine, will, I believe, readily occur to every person who at all thinks for himself, aiid is acquainted with the Systems which have hitherto prevailed. While, therefore, I attempt this, I think it may be allowable, and upon this occasion even proper, that I should offer some remarks on the principal Systems of Medi- cine which have of late prevailed in Europe, and that I should take notice of the present state of Physic as it is influenced by these. Such remarks, I hope, may be of some use to those who attempt to improve their knowledge by the reading of books. Whether *the practice of Physic should admit of reasoning, or be entirely rested upon experience, has long been, and may still be, a matter of dispute. I shall not, however, at present, enter upon the discussion of this ; because I can venture to assert, that, at almost all times, the practice has been, and still is, with every person, founded more or less, upon certain principles established by reasoning ; and therefore, in attempting to offer some view of the present state of Physic, I.must give*an account of those systems of the principles of science which have lately prevailed, or may be supposed still to pre- vail in Europe. When, after many ages of darkness, which had destroyed almost the whole of ancient.literature, learning was again restored in the fifteenth century ;* so from causes which are well known, it was the * At this period the medical knowledge of Europe was chiefly, and indeed Solely, such as had been derived from, the Arabians. At the conquest of Con- stantinople by the Turks, about the middle of the fifteenth century, several of the Greeks fled into Italy, and the people of Europe communicating with them, found them to be intelligent, and some of them even learned men; the Europeans were thence led to study the Greek language, in order to read the Valuable books which these fugitives had so much extolled ; and among other "Works, those of Galen particularly attracted the notice of the physicians, which to their great astonishment, contained all the medical kaow ledge that PREFACE. ju system of Galen alone that the Physicians of those days became ac- quainted with ; and during the course of the sixteenth century, the study of Physicians was almost solely employed in explaining and con- firming that system. Early, indeed, in the sixteenth century, the no- ted Paracelsus * had laid the foundation of a Chemical system which was in direct opposition to that of Galen ; and, by the efficacy of the medicines employed by Paracelsus and his followers, their system came to be received by many : but the systematic Physicians continued to be chiefly Galenists, and kept possession of the Schools till the middle of the seventeenth century. It is not, however, necessary here to en- ter into any further detail respecting the fate of those two opposite sects ; for the only circumstance concerning them, which I would at present point out, is, that in the writings of bothy the explanations they severally attempted to give of the phenomena of health or sick- ness, turned entirely upon the state of the fluids of the body. Such was the state of the science of physic till about the middle of the seventeenth century, when the circulation of the blood came to be generally known and admitted ; and when this, together with the dis- covery of the receptacle of the chyle, and of the thoracic duct, finally" exploded the Galenic system. About the same period a considerable revolution had taken place in the system o£ Natural Philosophy. In the course of the seventeenth century, Galileo had introduced mathe- matical reasoning ; and Lord Bacon having proposed the method of induction, had thereby excited a disposition to observe facts, and to make experiments. These new modes of philosophizing, it might be supposed, would soon have had some influence on the state of medi- cine ; but the progress of this was slow. The knowledge of the Cir- culation did indeed necessarily lead to the consideration as well as to a clearer view of the Organic System in animal bodies ; which again led to the application of the mechanical philosophy towards explaining had been attributed to the Arabians. To the Greek writers, therefore, the physicians of those times closely applied their attention, thinking these books the only true fountains of medical knowledge ; and thus it was that the Ga* lenical doctrines became prevalent all over Europe.. * The remarkable circumstances in the life oFAureohis PSilippus Theophra-- stiis Bombastus Paracelsus de Hobeiiheim, as he called himself, are too numer- ous for insertion in the narrow limits allotted to these Notes. He was born at the village of Einfidlen, about two German miles from Zurick, in the year1 1493. At three years old he was made an eunuch by an accident. He tra- velled all over the continent of Europe, obtaining knowledge in chemistry and physic, and then travelled about the country practising what he had learned. His chief remedies were opium and mercury, and his great success increased his celebrity. He cured the famous printer Ffobeniw of Basil of an inveterate disease ; this cure brought him acquainted with Erasmus, and made him known to the magistracy of Basil, who elected ham professor in 1527. He lectured two hours every day. While seated in hisVhair, he burnt with great solemnity, the writings of Galen and Avtcenna; and declared to his- audience, that if God would not impart the secrets of physic, it was not on- ly allowable, but even justifiable to consult the devil. He soon left Basil, and continued to ramble about the country, generally intoxicated, and never chang- ing his clothes, or even going to bed. He died after an illness of a few days,. in- an inn at Saltsbiirgh, in 1541, in his 48th year, tho' he had promised him- Wlf, that, by tne use of his ellxer, he should live to the age of Methusalem. *u PREFACE. the phenomena of the animal ceconomy; and it was applied accord- ingly, and continued, till very lately, to be the fashionable mode of reasoning on the subject. Such reasoning, indeed, must still in several respects continue to be applied : but it would be easy to show, that it neither could, nor ever can be, applied to any great extent in ex- plaining the animal oecononay ; and we must therefore look for other circumstances which had a greater share in modelling the system o£ Physic. With this view, it maybe remarked, that till the period just now mentioned, every Physician, whether Galenist or Chemist, had been so much accustomed to consider the *tate and condition of the fluids, both as the cause of disease, and as the foundation for explaining the operation of medicines, that what we may term an Humoral Pa- thology still continued to make a great part of every system. In these circumstances, it was soon perceived, that chemistry promised a much better explanation than the Galenic or Aristotellian philoso- phy had done ; and, therefore, while the latter was entirely laid aside, a chemical reasoning was every where received. Lord Bacon with his usual sagacity, had early observed, that chemistry promised a greater number of facts, and he thereby gave it credit ; whilst the Gorpuscularian philosophy, restored by Gassendi, readily united with the reasonings of the Chemists ; and the philosophy of Des Cartes readily united with both. From all these circumstances, an Humoral, and chiefly a Chemical Pathology, came to prevail very much till the end of the last century ; and has indeed, continued to have a great share in our systems down to the present time. It is proper now, however, to observe, that about the beginning of the present century, when every part of science came to be on a more improved and correct footing, there appeared in the writings of St ah l, of Hoffman, and of Boerhaavk, three new, and considerably dif- ferent, Systems of Physic ; which have ever since had a great share in directing the practice of it. In order, therefore, to give a nearer view of the present state of Physic, I shall offer some remarks upon these different systems ; endeavoring to point out the advantages, as well as the disadvantages of each, and how far they still prevail ; or, according to my judgment deserve to do so. I shall begin with considering that of Dr. Stahl, which I think appeared first, and for a long time after was the pre\ ailing system in Germany. The chief and leading principle of this system is, that the rational soul of man governs the whole ceconomy of his body. At all times, Physicians have observed, that the animal ceconomy has in itself a power or condition, by which, in many instances, it resists the inju- ries which t! reaten it ; and by which it also, on many occasions, cor- rects or removes the disorders induced, or arising in it. This power, Physicians very anciently attributed, under a vague idea, to an agent in the system, which they called nature ; and the language of a vis conservatrix et medicatrix naturae, has continued in the schools of medicine from the most ancient times to the present. Dr. Stahl has explicitly founded his system on the supposition that the power of nature, so much talked of, is entirely in the rational soul. PREFACE. 2U11 He supposes, that upon many occasions, the soul acts independently of the state of the body ; and that, without any physical necessity arising from that state, the soul, purely in consequence of its intelli- gence perceiving the tendency of noxious powers threatening, or of disorders any wise arising in the system, immediately excites such mo- tions in the body as are suited to obviate the hurtful or pernicious eonsequences which might otherwise take place.—Manv of my rea- ders may think it was hardly necessary for me to take notice of a system founded upon so fanciful an hypothesis ; but there is often so mucfi seeming appearance of intelligence and design in the operati- ons of the animal ceconomy, that many eminent persons, as Perrault in France., Nichols and Mead in England, Porterfield and Simson in Scotland, and Gaubius in Holland, have very much countenanced the same opinion, and it is therefore certainly entitled to some regard. It is not, however, necessary for me here to enter into any refutation of it. Dr. Hoffman has done this fully, in his Commentarms de dif- ferentia inter Hoffmanni doctr'nium medico-mtchanicam et G. E. Stahlii medico-organicam ; and both Boerhaave and Haller, though, no favorers of materialism, have maintained a doctrine very opposite to that of Stahl. In my Physiology I have offered some arguments against, the same ; and I s*hall only add now, that whoever considers what has been said by Dr. Nichols in his Oratio de Anima Jledica, and by Dr. Gaubius in some parts of his Pathology, must perceive, that the admitting of such a capricious government of the animal oeconomy, as these authors in some instances suppose would at once lead us to reject all the phy- sical and mechanical reasoning we might employ concerning the hu- man body. Dr. Stahl himself seems to have been aware of this ; and therefore, in his preface to Juncker's Conspectus Therapeia Specialise has'acknowledged, that his general principle was not at all necessary; which is in effect saying that is not compatible with any system of principles that ought to govern our practice. Upon this footing, I might have at once rejected the Stalilion principle ; but it is even dangerous to bring any such principle into view ; for, after all Dr, Stahl had said in a passage just now referred to, I find, that, in the whole of their practice, both he and his fpllowers have been very much governed by their general principle. Trusting much to the constant attention and wisdom of nature, they have proposed the Art of curing by expectation ; have therefore, for the most part, proposed only very inert and frivolous remedies ; have zealously opposed the use of some of the most efficacious, such as opium and the Peruvian bark ; and are extremely reserved in the use of general remedies, such ai bleed- ing, vomiting, &c. Although these remarks, upon a system which may now be consi- dered as exploded or neglected, may seem superfluous ; I have been willing to give these strictures on the Stahlion system, that I might carry my remarks a little farther, and take this opportunity of obser- ving*, that, in whatever manner we may explain what have been called the operations of nature, it appears to me, that the general doctrine of Nature curing diseases, the so much vaunted Hippocratic method of curing, has often had a baneful influence on the practice of physic '9 jdv PREFACE. as either leading physicians into, or continuing them in, a vrez\ r.n3 feeble practice ; and at the same time superceding or discouraging" all the attempts of art. Dr. Huxbam has properly observed that even in the hands of Sydenham it had this effect. Although it may" sometimes avoid the mischiefs of bold and rash practitioners, yet it certainly produces that caution and timidity which have ever opposed the introduction of new and efficacious remedies. The opposition to chemical medicines in the sixteenth and seventeenth centuries, and the noted condemnation cf Antimony by the Medical Faculty of Pa- ris, are to be attributed chiefly to those prejudices, which the physi- cians of France did not entirely get the better of for near an hundred years after. We may take notice of the reserve it produced in Boer- haave, with respect to the use of the Peruvian Bark.- We have had lately published, under the title of Constitutiones Epidemic*, notes of the particular practice of the late Baron Van Swieten ; upon which the editor very properly observes, That the use of the bark, in ir/ter- mitting fevers, appears very rarely in that practice j and we know very well where Van Swieten learned that reserve. 1 might go farther, and show how much the attention to the Auto~ crctcia, allowed of, in one shape or other, by every sect, has corrupted the practice among all physicians, from Hippocrates to Stahl. It must, however, be sufficiently obvious, and I shall conclude the sub- ject with observing, that altho' the v'.s medicatrix natura, must un- avoidably be received as a fact ; yet whether it is admitted, it throws an obscurity upon our system ; and it is only where the impotence of our art is very manifest and considerable, that we ought to admit of it in practice. To finish our remarks upon the Stahlion System, I shall shortly observe, that it did not depend entirely upon the Autocrateia, but al- so supposed a state of the body and diseases, that admitted of reme- dies ; which, under the power and direction of the soul, acted upon the organization and matter of the body, so as to cure its diseases. Upon this footing, the Stahlion pathology turned entirely upon Ple- thora and Cacochymy. It was with respect to the former that they especially applied their doctrine of the Autocrateia in a very fanati- cal manner ; and, with respect to the latter, they have been involved in a humoral pathology as much as the systematic physicians who had gone before them, and with a theory so incorrect as not to merit the smallest attention. After all, I ought not to dismiss the considera- tion of the Stahlion system, without remarking, that as the followers of this system were very intent upon observing the method of nature, so they were very attentive in observing the phenomena of diseases, and have given us in their writings many facts not to be found else-- where. While the doctrines of Stahl were prevailing in the university of' Halle, Dr. Hoffman,* a professor in the same university proposed a * Frederick Hoffman was born at Halle, in the year 1660. He graduated in 1681 ; was made professor of physic there in the year 1693 ; and hlledthat chair till his death in 1742. A very remarkable circumstance of his life is, that he never took fees from his patients, but was content with his stipend. He was in high repute as a practitioner, and curing the Emperor Charles VI. PREFACE, xv system that was very different. He received into his system a great deal of the mechanical, Cartesian, and chemical doctrines of the sys- tems which had appeared before: but with respect to these, it is of no consequence to observe in what manner he modified the doctrines of his predecessors, as his improvements in these respects were no ways considerable, and no part of them now remain ; and the real value of his works, beyond what 1 am just now going to mention, rests entire- ly on the many facts they contain. The merit of Dr. Hoffman and of his works is, that he made, or rather suggested, an addition to the system, which highly deserves our attention. Of this I cannot give a clearer account than by giving it in the author's own words. In his Medicina Rationales Systematica, Tom III. § l.chap. iv. he has given his Genealcgia mcrborum ex turbato solidurvm et fluidorum me- chanismo ; and in the 47th and last paragraph of this chapter he sums up his doctrine in the following words : Ex hisce autcm omnibus ub^- rius hactenus excussis,per quam dilucide apparere arbitror, qucd solus spasmus et simplex A7'okia, aquabilem, liberum, acproportionatum sanguinis omnisque generis fluidorum motum, quibus excretior.um sue- cessus et integritas functionum animi et corporisproxime nititur, tur- bando acpervertendo, universam vitalem aconomiam subruant ac destru- ant; atque hinc universa pathologia longe rectius atque facilius ex VltlO MOfUUM MICROCOSMICORUM IN SOLIDIS, quam EX VARUS AF- rECTioyjBus yiTiosoauM humorum, deduci atque explicari possit, adeoque omnis generis agritudines intern*, ad fraeTernaTuhales generis nerposi affectiones sint referenda.

Hia works are collected into six volumes, folio, pub- lished at different times from 1748 to 1754. They abound with many useful practical directions; but at the same time, contain many frivolous remarks, and an abundance of conjectural theory. Xvi P R E F A C E. rnotus allerr.ndo ac moderando, suam edunt operationem : De quibus tameti omnibus, in vulgari usque eo recepta morborum doctrina, ahum est silentium. It is true that Dr. Willis * had laid a foundation for this doctrine, in his Pathologia Cerebri et Nervorem; and Baglivi had proposed a system of this kind in his Specimen de flbra motrici et morbosa. But in these writers it was either not extensively applied to diseases, or was still so involved in many physiological errors, that they had at- tracted little attention; and Dr. Hoffman was the first who gave any tolerable simple and clear system on the^ subject, or pointed out any extensive application of it to the explanation of diseases. There can^e no sort of doubt that the phenomena of the animal ce- conomjf in health and in sickness, can only be explained by consider- ing the state and affections of the primary moving powers in it. It is to me surprising that physicians were so long in perceiving this, and I think we are particularly indebted to Dr. Hoffman for putting us into the proper train of investigation; and it every day appears that Physicians perceive the necessity of entering more and more into this inquiry. It was this, I think, which engaged Dr. Kaaw Boerhaave to publish his work entitled Impetum faciens ; as well as Dr. Gaub- us to give the Pathology of the Solidum vivum. Even the Baron Van Swieten has upon the same view thought it necessary, in at least one particular, to make a very considerable change in the doctrine of his master, as he has done in his Commentary upon the 755th Apho- rism. Dr. Haller has advanced this part of science very much by his experiments on irritability and sensibility. In these and in many other instances, particularly in the writings of Mr. Barthez of Mont- pelior, of some progress in the study of the affections in the Nervous System, we must perceive how much we are indebted to Dr. Hoff- man for his so properly beginning \t. The subject, however, is diffi- cult : the laws of the Nervous System, in the various circumstances of the animal ceconomy, are by no means ascertained ; and, from want of attention and observation with the view to a system on this subject, the business appears to many as an inexplicable mystery. There is no wonder therefore, that on such a difficult subject, Dr. Hoffman's system was imperfect and incorrect; and has had less in- fluence on the writings and practice of Physicians since his time, than might have been expected. lie himself has not applied his funda- mental doctrine so extensively as he might have done ; and he has every where intermixed a Humoral Pathology, as incorrect and hy- pothetical as any other. Though he differed from his colleague Dr. • This illustrious physician was born at great Bedwin in Wiltshire in 1621. He took the degree of master of arts in 1642 at Oxford, where he was made professor of natural philosophy in 1660 : and that same year he took the de- gree of M. D. His practice was extensive and successful. He was one of the first members of the royal society in London, whither he removed in 1666 ; and soon made his name as illustrious by his writings, as he had al- ready done by his practice. His works had been often printed separately ; but they were not collected till after his death, which happened on the 1 ith of November, 1675. One edition was published at Geneva in 1676, and another at Amsterdam in 1682, both in quarto. PREFACE. xvii Stahl in the fundamental doctrines of his system, it is but too evident that he was very much infected with the Stahlian doctrines of Plethora and Cacochymy, as may be observed throughout the whole course of his work ; and particularly in his chapter De morborum generatione ex ni- mia sanguinis quantitate et humoruui impur it ate. But it is needless for me to dwell any longer upon the system of Hoff- man ; and I am next to offer some remarks on the system of Dr. Boer- haave the cotemporary of both the other Systematics,and who, over all Europe, and especially in this part of the world, gained higher reputa- tion than either of the others. ' Dr. Boerhaave * was a man of general erudition ; and, in applying to medicine, he had carefully studied the auxiliary branches of Anatomy, Chemistry, and Botany, so that he excelled in each. In forming a Sys- tem of Physic, he seems to have studied diligently all the several wri- tings of both ancient and modern Physicians ; and, without prejudice in favour of any former systems, he endeavoured to be a candid and genuine ecclectic. Possessed of an excellent systematic genius, he gave a system superior to any that ever before appeared. As in the great * Voorhoot, a small village about two miles from Leyden, gave birth to this eminent physician on the last day of the year 1668. He was educated at Leyden, and took his first degree in philosophy in 1690. His thesis on this occasion was a confutation of the doctrines of Epicurus, Hobbes, and Spinosa, in which he shewed great strength of genius and argument. Al- though he was at this time well qualified to enter into the church, which was his father's intention, yet he was difhdent of his abilities, and chose to at- tend the lectures of divinity longer. His patrimony was however now ex- hausted, and he supported himself at the university by teaching mathema- tics, while he prosecuted his theological studies. This conduct was much approved by the eminent men both of the University and City, and procured for Boerhaave the friendship of Mr. Vanderburg the Burgomaster of Leyden. Under the patronage, and at tha persuasion of this gentleman, Boerhaave applied himself to the study of physic with great ardor and indefatigable di- ligence. In a short time he became proficient in anatomy, chemistry, and the materia medica, which indeed are the basis of physic. Leaving Leyden he went to the university of Harderwick in Guelderland, and there took his degree of Doctor of Physic in July 1693. On his return to Leyden he stiil persisted in his intention of entering into the ministry, which luckily, for the sake of Physic, was frustrated by the following adventure : In a passage- boat where Boerhaave was, a discourse was accidentally started about the doctrines of Spinosa, as subversive of religion ; and one of the passengers, with vague invectives of blind zeal, opposed this philosopher's pretended mathematical demonstration. Boerhaave calmly asked him if he had read Spinosa's work, which he had so much derided. The bigot was suddenly struck dumb, and became fired with silent resentment. As soon as he arri- ved at Leyden, he spread abroad a rumor that Boerhaave was become a Spi- nosist. Boerhaave finding these prejudices to gain ground, thought it more prudent to pursue the science of physic, than risk the refusal of a licence for the pulpit. He now joined the practice of physic to the theory. On the r8th of May, 1701, he commenced his lectures on the Institutes of physic. In 1709 he was created professor cf medicine and botany; and in 1718 he succeeded Le Mort in the professorship of Chemistry. In August 1722, he was seized with the gout, and was obliged to resign his professorship of Che- mistry and Botany in 1729. He continued for some time to practice, but was at length obliged to quit that also j and he died on the 23d of September 1738. Vol. I. C xviii PREFACE, extent, and seemingly perfect consistency, of system, he appeared to improve and refine upon every thing that had before been offered ; and as in his Lectures he explained his doctrines with great clearness and elegance ; he soon acquired a very high reputation, and his sys- tem was more generally received than any former had been since the time of Galen. Whoever will consider the merits of Dr. Boerhaave, and can compare his system with that of former writers, must acknow- ledge that he was very justly esteemed, and gave a system which was at that time deservedly valued. But, in the progress of an inquisitive and indrustrious age, it was not to be expected that any system should last so-long as Boerhaave's" has done. The elaborate -Commentary of Van Sweiten on Boerhaave'* system of practice, has been only finished a few years ago ; and though this Commentator has added'many facts, and made seme corrections, he has not, except in the particular mentioned above, made any im- provement in the general system. It "rs even surprising that Boer- haave himself, though he lived near forty years after he had first form- ed his system, had hardly in all that time made any corrections of it or additions to it; the following is the most remarkable. In Apho- rism 75 5, the words forte et nervosi, tarn cerebri quam cerebelli cordi destinati inertia, did not appear in any edition before the fourth ; and what a difference of system this points at, eveiy physician must perceive. When I first applied to the study of Physic, I learned only the sys- tem of Boerfeaave ; and even when 1 came to take a Professor's chair in this university, I found that system here in its full force ; and as I believe it still subsists in credit elsewhere, and that no other system of reputation had been offered to the world, I think it necessary for me to point out particularly the imperfections and deficiencies of the Boerhaavian system, in-order to show the propriety and necessity of attempting a newone. To execute this,.however, so fully as I might, would lead me into a detail that can hardly be admitted of here ; and I hope it is not ne- cessary, as I think, that every intelligent person, who has acquired any tolerable knowledge of the present state of our science, must in many instances, perceive its imperfections. I shall therefore touch only upon the great lines of this system ; and from the remarks I am to offer, trust that both the mistakes and deficiencies which run through the whole of his works will appear. Dr Boerhaave's treatise of the diseases of the simple solid, has the appearance of being very clear and'Consistent, and was certainly con- sidered by him as a fundamental doctrine ; but, in my apprehension, it is neither correct nor extensively applicable. Not to mention the useless, and perhaps erroneous, notion of the composition of earth and gluten ; nor his mistake concerning the structure of compound mem- branes ; nor his inattention to the state of the cellular texture ; all of them circumstances which render his doctrine imperfect ; I shall insist only upon the whole being very little applicable to the explain- ing the phenomena of health or sicknes:. The laxity or rigidity of the simple solid, does, indeed, take place at the different periods of life, and may perhaps, upon other occasions, occur as the cause ot* disease : P'REFAC E. xi:! But I prrrjmr, that the state of the simple solid is, upon few occasi- ons, either changeable or actually changed ; and that, in ninety-nine cases of an hundred, the phenomena attributed to such a change, do truly depend on the state of the solidum vivum ; a circumstance which Dr. Boerhaave lias hardly taken notice of in any part of his works. How much this shows the deficiency and imperfection of his svstem, I need not explain. The learned work of Dr. Gaubius, above referred to, as well as many other treatises of late authors, point out suffici- ently the defects and imperfections of Boerhaave on this subject. After Dr. Boerhaave has considered the deseases of the solids, he in the next place attempts to explain the more simple diseases of the fluids ; and. there, indeed, he delivers a more correct doctrine of acid and alkali than had been given before : But, after all, he has done it very imperfectly. We have, indeed, since his time, acquired more knowledge upon the subject of digestion -y and so much as to know, that a great deal more is yet necessary to enable us to understand in what manner the animal fluids are formed from the aliments taken in. And although Dr. Boerhaave has fallen into no considerable error with respect to a morbid acidity in the stomach, he could not possibly be compleat upon that subject ; and his notion of the effects of acU dity in the mass of blood seems to have been entirely mistaken, andj is indeed not consistent with what he himself has delivered elsewhere* His doctrine of alkali is somewhat better founded,, but is probably carried too far ;. and the state of alkalescency and putrefaction, as well as all. the other changes which can take place in the condition of animal fluids, are particulars yet involved in great obscurity, and are therefore stilL subject of dispute. There is another particular, in which Boerhaave's doctrine con- cerningthe fluids appears to me imperfect and unsatisfactory ; and that is, in his doctrine de Glutinoso spontanea. The causes which he has assigned for it are by no means probable, and the actual existence of it is seldom to be proved. Some of the proofs adduced for. the exist- ence of a phlegma calidum, are manifestly founded on a mistake with respect to what has been called the inflamatory crust, (see Van Swie- ten.'s Commentary, page 96.) and the many examples given by Boer- haave of a glutinosum appearing in the human body, (Aph.. 75.) are all of them nothing more than instances of collections or concretions found out of the course of the circulation. If, then, we consider the imperfections of Dr. Boerhaave's doctrine with respect to the state and various condition of the animal fluids ; and if at the same time we reflect.how frequently he and his follow- ers have employed the supposition of an acrimony or lentor of the fluids, as causes of disease,, and for directing the practice ; we must, as I apprehend, be satisfied, that his system is not only deficient and incomplete, but fallacious, and apt to mislead. Although it cannot be denied, that the fluids of the human body suffer various morbid changes ; and that upon these, diseases may primarily depend : yet I must beg leave to maintain, that the nature of these changes is sel- dom understood, and more seldom still is it known when they have ta- ken place: that our reasonings conceiving them have been, for the most part, purely hypothetical j have therefore contributed nothing to XX PREFACE. improve, and have often misled, the practice of physic. In this, par- ticularly, they have been hurtful, that they have withdrawn our at- tention from, and prevented our study of, the motions of the animal system, upon the state of which the phenomena of diseases do more certain and generally depend. Whoever, then, shall consider the al- most total neglect of the state of the moving powers of the animal body, and the prevalence of an hypothetical humoral pathology, so 'conspicuous in every part of the Boerhaavian System, must be con- vinced of its very great defects, and perceive the necessity of attempt- ing one more correct. After giving this general view, it is not requisite to enter into par- ticulars ; but, I believe, there are very few pages of his aphorisms in which there does not occur some error or defect; although, perhaps, not to be imputed to the fault of Boerhaave, so much as to this, that since his time a great collection of new facts has been acquired by observation and experiment. This, indeed, affords the best and most solid reason for attempting a new system : for when many new facts have been acquired, it becomes requisite that these should be incor- porated into a system, whereby not only particular subjects may be improved, but the whole maybe rendered more complete, consistent, and useful. Every system, indeed, must be valued in proportion to the number of facts that it embraces and comprehends ; and Mons. Ouesney could not pay a higher compliment to the system of Boer- haave, than by saying that it exhibited La medicine collective. But here it will, perhaps be suggested to me, that the only useful work on the subject of physic, is the making a collection of all the facts that relate to the art, and therefore of all that experience has taught us with respect to the cure of diseases. I agree entirely in the opinion; but doubt if it can ever be properly accomplished, with- out aiming at some system of principles, by a proper induction and generalisation of facts : at least I am persuaded that it can be done not only very safely, but most usefully in this way. This, however, must be determined by a trial. I know that the late Mr. Lieutaud has attempted a work on a plan of collecting facts without any rea- soning concerning their causes : And while I am endeavoring to give some account of the present state of physic, I cannot dismiss the sub- ject without offering some remarks upon the promising Synopsis uni- versa medicina, composed by the first physician of a learned and in- genious nation. In thii work there are many facts and much observation from the Author's own experience, which may be useful to those who have otherwise some knowledge and discernment; but, throughout the whole work, there is such total want of method, arrangement, system, or decision, that in my humble opinion, it can be of little use, and may prove very perplexing to those who are yet to learn. The distinction of the genera of diseases, the distinction of the species of each, and often even that of the varieties, I hold to be a necessary foundation of every plan of physic, whether dogmatical or empirical. But very little of this distinction is to be found in the work of Mr. Lieutaud ; and in his preface he tells us, that he meant to neglect such arguta sedulitas. And indeed his method of managing his subject must cer- PREFACE. xxi tainly interrupt and retard all methodical nocclogy. His arrangement of diseases is according to no affinity, but that of the slightest and un- instructive kind, the place of the body which they happen to aif ct. His Gene: alia et incerta sedis, have hardly any collection at all ; the titles Rutumatisms, Hypocondriasis, Hydrops, follow one another. When he does attempt any geneivl doctrine, itMs not till lon^ after he has treated of the widely scattered particulars. Under each par- ticular title which he assumes, he has endeavored to enumerate the whole of the symptoms that ever appeared in a disease under that t'. tie ; and this without aiming at any distinction between the essen- tial and accidental symptoms, or marking the several combinations under which these symptoms do for the most part steadily appear. From the concurrence of accidental symptoms, the variety of the same disease is frequently considerable, u circumstance necessarily perplex- ing and distracting to young practitioners ; but it seems "strange to me, that an experience of thiity years, inconsiderable practice, could do nothing to relieve them. Mr. Lieutaud has at the same time increased the confusion that must arise from this want of distinction, by his considering as pri- mary diseases, what appear to me to be the symptoms, effects, and se- quels, of other diseases only. Of this I think the AZitus morbjsus, Virum exolutio, Dolores, Stagnatio sanguinis, Purulentia, Tremor, Hervigilium, Raucedj, Su/focatio, Vomica, Empyema, Singultus, Vo- mitus, Dolor Stomachi, Tenesmus, all treated cf under separate titles, are examples. A general symptomatologia may be a very useful work, with a view to a System of Pathology ; but with a view to practice without any System, it must have bad effects as leading only to a pal- liative practice, and diverting from the proper efforts towards obtain- ing a radical cure. Mr. Lieutaud, indeed, has endeavoured to exhi- bit the symptoms above mentioned as so many primary diseases: but he has seldom succeeded in this ; and, in delivering the practice he com- monly finds it necessary to consider them as symptoms, and that not without some theory, implied or expressed, with respect to their prox- imate causes. His title of Dolores may be tuk-rn as an example of this ; and from which it may be readily perceived how fir such treati- ses can be really useful. In establishing a proper pathology, there is nothing that has been of more service than the dissection of morbid bodies. Mr. Lieutaud has been much and most commendably employed in this way, and in this Synopsis he has endeavoured no communicate his knowledge on the subject ; but in my humble opinion, he has seldom done it in a manner that can be useful. In the same way that he has delivered the symptons of diseases without any instructive arrangement ; so on the subject of the appearances after death, he has mentioned every morbid appearance that had ever been observed after the disease of which he is then treating : but these appearances are strangely hud- dled together, without, any notice taken of those which belong to one set of symptons or to another; and with regard to the whole, without any attempt to distinguish between the causes of diseases and the cuj- ses of death ; although the want of such distinction is the well known ground of fallacy upon this subject. I take for an example, the ap- saii PREFACE. pr:.rnnc?s mentioned ss having been observed after dropsy. Here ni 'reed appearances, found in every part of tie body, in. every cavity of it, and in every viscus contained in these cavities, are enumerated : but which of these morbid states are more frequent or more rare, and which has been more particularly connected with the different causes or with the different state of symptoms previously recited, we are not informed, nor h.is he enabled us to discover. In short, the dissection of morb.d bodies has been, and may beT highly useful ; but in order to be so, must be under a different management from what we find either in this Synopsis, or even in the Historia Anatomico medica. Icannotdlsmissthis subject without remarking, that the dessection of morbid bodies, is chiefly valuable upon account of its leading us to discover the proximate causes of diseases ; and the great and valua- ble work of the illustrious Morgagni is properly intkled De sidJmsct cavsis. It may well seem surprising, then, that Lieutaud should find the wh< le of proximate causes atra calagine mersas ; and that he should never have thought of applying his dissections towards the ascertaining at least some of these. But let me now proceed to consider the important part of every practical work, and of this Synopsis universa medicina : that is, the method of curing diseases. Here, again, upon the same plan as i:i giving the histories of dis- ease, the method of cure is delivered by enumerating the whole of the remedies that have ever been employed in a disease under the title pre- fixed ; without assigning the species, or the circumstances to which the remedies, though of a very different and sometimes opposite na- ture, are particularly adapted. O;* the subject of Asthma he very justly observes that physicians have been to blame in confounding, un- der this title, almost all the species of Dyspnoea ; and he himself very properly considers Asthma as a disease distinct from all the other cases of Dyspnoea. Still, however, he considers Asthma zs of many different species, arising from many different causes, which till we understand better, we cannot attempt to remove. Notwithstanding •ill this, he proceeds to deliver a very general cure. Parum abest, says he, quia specifici titulogaudeant pectoralia, xulneraria, et incidentia 1 But from such language I receive no clear idea ; nor can I obtain any clear direction from the enumeration of his medicines. Bacca juniper-, gummi, tragacanteum vel ammoniacum, sapo aqua j'lcea, te- rcoiiii'iina, isfc. qua tamen hand indiscriminatim sunt usurpandar sed pro re nata, deluctu opus est. Very justly indeed, deluctu opus est; but here, as in many other instances, he gives us no sort of assistance. , From his endeavours, though not always successful, to neglect all system, his practice is generally delivered in a very indecisive man- ner; or, what has the same effect, in a way so conditional as will render it always difficult, and often impossible, for a young practiti- oner to follow him. Let us take, for example, his cure of Dropsy, " The cure may be begun by blood-letting in certain conditions ; but in others, it cannot be employed without danger. It gives relief in difficult breathing; but, after it is practised, the symptoms are ag- gravated, and rendered more obstinate. It is not to be concealed that ao:ne persons have been cured by repeated blood-lettings, or sponta- PREFACE. xnii neous hErnorrhagies ; but it is at the same time known, that such a remedy inopportunely employed, has in many instances hastened on the fatal event." In the same manner he treats of vomit;rig, purging, sweating, and the use of mineral waters ; but I must confess, that he has no where removed any of my doubts or difficulties, and indeed he has sometimes increased them. He says, that hepatics, or aperients, such as the lingua" ctriir.a, herba capillares, Isfc. deserve commendation ; but that when the disease has arisen to a certain degree, they have been,yi/r the most part, found to be useless. He observes, that the powder of toads given in wine, to the quantity of a scruple more, has succeeded with severals. Such are commonly, the methods of cure delivered by Mr. Lieu- taud, lengiori et fortefelicissima praxi ed'jetus. It '.\ould be tedious to enter further into that detail, which a cri- tic i-sm of this unmethodical and uninstruc-ive work might lead me into ; but, if the bounds proper for this preface did not prevent me, I would particularly show that the work is far from being free from those reasonings which the author pretends to avoid, and would affect even to despise. He still holds the doctrine? of the concoction and cri- tical evacuation of morbific matteu; doctrines depending vpon subtile theories, and which, in my opinion, can in no wise be ascertained as matters of fact. Mr. Lieutaud likewise is still very much upon the old plan of following nature, and therefore gives often what 1 consider as a feeble and inert practice. The hamectan- tia, dilueniia, demulcentia, et temperantia, are with him very uni- versal remedies, and often those Which alone are to be employed. The mention of these medicines might lead me to take notice'of Mr. Lieutaud's second volume, in which, ab insula remedivrum far- ragine alienus, he promises a great reformation upon the subject; but this falls so far short of the idea of British physicians, that I need not make any remarks upon it. With respect to his list of simples, or Emporetica, as he is pleased to term them, an English apothecary would smile at it; and with respect to his Officinal:a, I believe they are to be found no where but in the Codex Medio a;nc:itarius of Paris; and i:i his Magistralia his doses are generally such as the most timid practitioner of this country would hardly descend to, and such as none of our practitioners of experience would depend upon. In short, the whole of the work, both with respect to the theories with which it a- bounds, and to the facts which it gives', will not, in my apprehension, bear any serious criticism. But 1 must conclude ; and shall only say further, that such as I have represented it, is this work, executed by a man of the fir t rank in the profession. It is indeed tor that reason I have chosen it as the example of a work, upon the plan of giving facts only, and of avoiding the study or even the notice of the proximate causes of diseases ; and with what advantage such apian is pursued, I shall leave my readers to consider. In the following treatise I have followed a different course. I have endeavoured to collect the facts relative to the diseases of the human body, as fully as the nature of the work and the bound* necessarily prescribed to it would admit: But I have not been satiiiied with giv- XXIT PREFACE. ing the facts, without endeavouring to apply them to the investigati- on of proximate causes, and upon these to establish a more scientific and decided method of cure. In aiming at this, I flatter myself that I have avoided hypothesis, and what have been called theorie^. 1 have, indeed, endeavoured to establish many general doctrines, both physi- ological and pathological ; but I trust that these are only a generalisa- tion of facts, or conclusions from a cautious and full induction ; and if'any one shall refuse to admit, or directly shall oppose, my general doctrines, he must do it by showing that I have been deficient or mis- taken in assuming and applying facts. I have, myself, been jealous of my being sometimes imperfect in these respects ; but I have gene- rally endeavoured to obviate the consequences of this, by proving, that the proximate causes which I have assigned, are true in fact, as well as deductions from any reasoning that I may seem to have em- ployed. Further, to obviate any dangerous fallacy in proposing a method of cure, I have always been anxious to suggest that which, to the best of my judgment, appeared to be the method approved of by experience, as much as it was the consequence of system. Upon this general plan I have endeavoured to form a system of physic that should comprehend the whole of the facts relating to the science, and that will, I hope, collect and arrange them in better order than has been done before, as well as point out in particular those which are still wanting to establish general principles. This which I have attemped may, like other svstems, hereafter suffer a change ; but I am confident that we are at present in a better train of investigation than physicians were in before the time of Dr. Hoffman. The affections of the motions and moving powers of the animal eco- nomy, must certainly be the leading inquiry in considering the disea- ses of the human body. The inquiry may be difficult ; but it must be attempted, or the subject must be deserted altogether. I have there- fore, assumed the general principles of Hoffman, as laid down in the passage which I have quoted above ; and if I have rendered them more correct, and more extexisive in their application ; and, more particu- larly, if I have avoided introducing the many hypothetical doctrines of the Humoral Parthology which disfigured both his and all the other systems which have hitherto prevailed ; 1 lupe 1 shall be excused for attempting a system, which upon the whole nu.y appear new.

J.N teaching the Practice of Physic, we endeavor to give inftru6tion for discerning, distinguishing, prevent- ing and curing difeafes, as they occur in particular per- fons. 2.] The art of discerxing and distinguishing ditcafcs, may be beft attained by an accurate and complete obfervation of their phenomena, as thefe occur in con- courfe and in fucceflion, and by constantly endeavoring to diitinguifh the peculiar and infeparablc concurrence of iymptoms, to eitablifh a Methodical Nosolocy, or an arrangement of difeafes according to their genera and fpecies, founded upon obfervation alone, abftra&ed from all reafoning. Such an arrangement I have attempted in another work, to which in the courfe of the prefent I mall frequently refer. 3.J The prevention of difeafes depends upon the knowledge of their remote caufes ;* which is partly deli- vered in the general Pathology, and partly to be delivered in this treatife. * Remote causes are of two kinds, viz. the predisposing'and the exciting, err, as it is sometimes called, the occasional. The predisposing is that which renders the body liable or capable of being affected by disease when the ex- 1 iting cause is applied. No disease can exist without an occasional cause ; yet it is r.ececsarv, that at the same time, the state of the body should be such as to admit that cause to take effect, or act. The predisposing cause is inhe- rent in the body ; but it may nevertheless be induced or changed by an ex- ternal cause still more remote. Thuspl^hora may be the predisposing cause cf manv diseases, yet that same plethora may be induced by various causes p;eviou.-.ly acting on the body. The prevention of diseases is to avoid the CAt-iting cause, and to correct that state of the body, which renders, it capa- ble cf being affected by the excising cause. V u. 1. D 26 PR A.C T I C E, &c. 4.] The Cure of difeafes is chiefly, and almoft unavoid- ably founded in the knowledge of their proximate cawfcs.* This requires an acquaintance with the Inititutions of Me- dicine ; that is, the knowledge of the ftrutture, action, and functions of the human body ; of the fevcral changes which it may undergo ; and of the fevcral powers by which it can be changed. Our knowledge of thcfe particulars, however, is Hill incomplete, is in many refpects doubtful, and has often been involved in mi (take and error. The doctrine, therefore, of proximate caufes, founded upon that knowledge, mult be IVcquently precarious and uncer- tain. It is, however, polfible for a judicious phyfician to 2void what is vulgarly called theory, that is, all reafoning founded upon hypothecs, and thereby many of the errors which have formerly taken place in the Inlcitutions of Me- dicine. It is polTiblc alio for a pcrfon who has an exten- five knowledge of the facts relative to the animal cecono- my in health and in ficknefs, by a cautious and complete induction, to eftablifh many general principles which may guide his reafoning with fafcty ; and while n the fame time, a phyfician admits-as a foundation of practice thole rcafonings only which are fimple, obvious and certain, and for the molt part admits as proximate caufes thofe alone that are eftablifhed a^ matters of fact rather than as deductions of reafoning, he may with oveat advan- tage -eftablifh a fyftem of practice chiefly founded on the doclrine of proximate caufes. But when this cannot be done with fufficient certainty, the judicious and prudent phyfician will have recourfe to experience alone ; al- ways, however, aware .of the hitherto incomplete and fal- lacious ftate of Empiricifm. 5.] With a ftrict attention to thefe confiderations in the whole of the following Treatife, I proceed to treat <*f par- ticular difeafes in the order of my Methodical Nofology. * Proximate causes are those which immediately produce the disease, and v.hose removal cures the diteaie. • • C 27 ] PART I. Of Pyrexia, or Febrile Diseases. 6.] JTYREXIiE, or febrile difeafes, are diftinguifhed b-y the following appearances. After beginning with fome degree of cold ihivering, they mow fome increafe of heatx and an increafed frequency of pulfe, with the interruption and diforder of fcveral functions, particularly fome dimi- nution of (trength in the animal functions. 7.J Of thefe Pyrexia: I have formed a clafs, and have fubdivided it into live orders of Fevers, In f l amm at i- OS's, Eruptions, Hemorrhages, and Fluxes.—■ See Synopfis Xofologiae Methodical, Edit. 3. 1780. =3 BOOK I.

But we luppofe, that there are certain circumftances in common to all the difeafes comprehended under this order, which are therefore thofe eilentially ncceffary to, and properly conftituting the na- ture of lever. It is our bufm<3fc efpecially, and in the lirft place, to inveftigate thefe; and I expect, to find them as they occur in the parox'yfm, or fit, of an intermittent fe- ver, as this is moil commonly formed. 28 PRACTICE io.] The phenomena to be obferved in fuch a paroxyfm are the following. The perfon is affe&ed, hrlt, with a languor or fenfe of debility, a fluggifhnefs in motion, and fome uneafinefs in exerting it, with frequent yawing and ftretching. At the fame time, the face and extremities be- come pale ; the features Hi rink ; the bulk of every exter- nal part isdiminifhed ; and the fkin over the whole body, appears conftricted, as if cold had been applied to it. At the coming on of thefe fymptoms, fome coldnefs of the extremities, though little taken notice of by the patient, may be perceived by another perfon. At length, the pa- tient himfclf feels a fenfation of cold, commonly firft in his back, but, from thence, palling over the whole body ; and now his fkin feels warm to another perfon. The pa- tient's fenfe of cold increafing, produces a tremor in all his limbs, with frequent fuccefnons or rigors of the trunk of the body. When this fenfe of cold, and its effects, have continued for fome time, they become lefs violent, and are alternated with warm flulhings. By degrees, the cold goes off entirely ; and a heat, greater than natural prevails, and continues over the whole body. With this heat, the color of the fkin returns, and a preternatural rednefs appears, efpecially in the face. Whillt the heat and rednefs comes on, the fkin is relaxed and fmoothed, but for fome time, continues dry. The features of the face, and other parts of the body, recover their ufual fize, and become even more turgid. When the heat, rednefs, and turgefcence have increafed and continued for fome time, a moifture appears upon the forehead, and by degrees becomes a fweat, which gradually extends downwards over the whole body. As this fweat continues to flow, the heat of the body a- bates; the fweat, after continuing fome time, gradually ceafes; the body returns to its ufual temperature ; and molt of the fun6tions are reftored to their ordinary ftate.* 11.] This feries of appearance give occafion to divide the paroxyfm into three different Itages; which are called the Cold, the Hot, and the Sweating Stages or Fits. In the courfe of thefe, Amhderable changes happen in * This description of a paroxysm is truly5admirable.

As the fenfe of cold comes on, the pulfe becomes fm.:!!cr, very frequent and often irregular. As the cold abates :u;d the heat comes on, the pulfe becomes more regular, hard, and full; and in thefe refpecls, increafes till the fv. cat breaks out. As the fweat flows, the pulfe becomes foft- er, and lefs frequent, till the fweat ceafing altogether, it returns to its ufual ftate. 13.] The refpiration alfo fuffers fome changes. During the cold ftagc, the refpiration is fmall, frequent, and anxi- ous, and is fometimes attended with a cough : as the hot ftage comes on, the refpiration becomes fuller and more free ; but continues 11 ill frequent and anxious, till the flow- ing of the fweat relieves the anxiety, and renders the breath- ing lefs frequent and more free. With the ceahug of the fwe'at, the breathing returns to its ordinary ftate. 14.] The natural functions alfo fuffer a change. Upon the approach of the cold ftage, the appetite for food ceafes and does not return till the paroxyfm be over, or the fweat has flowed for fome time. Generally, during the whole of the paroxyfm, there is not only a want of appetite, but an averfion from all folid, and efpecially animal food. As the cold ftagc advances, there frequently comes on a fick- nefs and naufea, which often ir.crcafe to a vomiting of a matter that is for the mod part bilious. This vomiting commonly puts an end to the cold ftage, and brings on the hot. As the hot ftage advances, the naufea and vo- miting abate ; and when the fweat breaks out they gene- rally ccafc altogether. 15.] A confiderablc degree of thirft is commonly felt during the whole courfe of the paroxyfm. During the cold itage, the thirft fecms to arife from the drynefs and clammmcfs of the mouth and fauces, but during the hot ftage, from the heat which then prevails over the whole bo- dy ; and as the fweat flows, the mouth become moifter, and the thirft, together with the heat gradually abates* * *The thirst in the cold and hot stac;.•. of the paroxysm seems to he a pro- vident design of nature, and has been held i'crth as an argument for the cJi- 3.0 PRACTICE 16.] In the courfe of a paroxyfm, there is often a con- siderable change in the ftate of the fecrctions. The circum- ftances juft now mentioned fhow it in the fecretion of the faliva and mucus of the mouth; and it is ftill more re- markable with refpetf to the urine. During the cold ftage, the urine is almoft colorlefs,and without cloud or fediment. In the hot ftage it becomes high colored, but is ftill with- out fediment. After the fweat has flowed freely, the urine depoflts a fediment, commonly lateritious, and continues to do fo for fome time after the paroxyfm is over. 17.] Excepting in certain uncommon cafes which are at- tended throughout with a diarrhaa, ftools feldom occur till towards the end of a paroxyfm, when commonly a ftool happens, which is generally of aloofe kind.* 18. J Analogous to thefe changes in the ftate of the fecrc- tions, it frequently happens, that tumours fubfifting on the furface of the body, fuller during the cold ftage of fevers, a fudden and conliderable detumefcence ; but generally, though not always, the tumours return to their former Iize during the fweating ftage. In like manner, ulcers are fometimes dried up during the cold ftage; and return a- gain to difcharge matter during the fweating ftage, or after the paroxyfm is oyer. 19.] Certain changes appear alfo in fenfation and thought. During the cold ftage, the fenfibility is often greatly im- paired ; but when the hot ftage is formed, the fenfibility is recovered, and often confiderably inereafed. 20.] With refpecl to the intellectual functions, when the cold ftagc comes on, attention and recollection become difficult, and continue mote or lefs fo during the whole istence of the vis medicatrix naturae. The paroxysm concludes with a pro- fuse sweat; the production of this sweat requires an additional quantity o£ fluidity; and nature, by means of the thirst, seems anxious to supply the quantity of fluid matter necessary lor the perspiration that is requisite to re- move the disease. * The author's expression is here somewhat aukward; the meaning of the passage is, that stools seldom occur in the two rirst stages of a paro.w mii, except in peculiar cases attended with diarrhoea ; and if a. stocl happens a'oout the end of the paroxysm, it is generally of a loose kind. A spontaneous diarrhoea always inoreases the violence of the symptoms, and the obstinacy of the disease. Hence the absurd practice of pix-scrihing purges in agues, which never fail to exacerbate the paroxysms, and pVlong their continuance. If any uneasiness arises from accumulated i\c:cs hi '.he colon or rectum, they may be removed by emollient clysters. OP P.H Y S IC. 31 paroxyfm. Hence fome confufion of thought takes place, and often arifes to a delirium, which fometimes comes on at the beginning of the cold ftage, but more frequently not till the hot ftage be formed. 21.] It belongs alfo to this place to remark, that the cold ftage fometimes comes on with a drowfinefs and ftupor, which often increafe to a degree that may be called coma- tofe, or apoplectic. . 22.] We have ftill to add, that fometimes, early in the cold ftage, a headach comes on; but which, more com- monly, is not felt till the hot ftage be formed, and then is ufually attended with a throbbing of the temples. The headach continues till the fweat breaks out; but as this flowrs more freely, that gradually goes off. At the fame time with the headach, there are commonly pains of the back, and of fome of the great joints; and thefe pains have the fame courfc with the headach. 2-3.] Thefe are nearly the whole, and are at leaf! the chief of the phenomena which more conftantly appear in the paroxyfm of an intermittent fever ; and we have point- ed out thvir ordinary concourfe and fucceflion. With re- fpecl to the whole of them, however, it is to be obferved, that in different cafes, the feveral phenomena are in differ- ent degrees ; that the feries of them is more or less com- plete ; and that the feveral parts or ftages in the time they occupy, are in a different proportion fo one another. 2.{.J It is very feldom that a fever confifts of a^fingle paroxyfm, fuch as we have now defcribed; and it m«re generally happens, after a certain length of time has elapfed from the ceafing of the paroxyfm, that the fame feries of phenomena again arifes, and obferves the fame courfe as before ; and thefe ftates of Fever and Apyrexia often continue to alternate with one another for many times. In fuch cafes, the length of time from one paroxyfm to the be- ginning of another, is called an Intermission ; and the length of time from the beginning of one paroxyfm to the beginning of another next fucceeding, is called an In ter- val. 25.] When the difeafe confifts of a number of parox- yfms, it is generally to be obferved, that the intervals be- tween them are nearly equal; twit thefe intervals are of 32 PRACTICE different lengths in different cafes. The mo ft ufual inter- val is that of forty-eight hours, which is named the Ter tia:\' period. The next molt common is that of feven- tv-two hours, and is named the Quartan period. Some other intervals are alfo obferved, particularly one of twen- ty-four hours, named therefore, the Quotidian; and the appearance of this is pretty frequent. But all other intervals longer than that of the quartan are extremely rare, and probably arc only irregularities of the tertian or quartan periods.* 26.] The paroxyfms of pure intermittent fevers are al- ways finifhed in lefs than twenty-four hours : and though it happens that there are fevers which confiit of repeated paroxyfms, without any entire mtermifnon between them ; yet in fuch cafes it is obferved, that though the hot and "fweating ftages of the paroxyfm do not entirely ceafe be- fore the twenty-four hours from their beginning have ex- pired, they fuffer, however, hefore that time, a conhderable a!:;: temei it or Remission of their violence; and at the re- turn of the quotidian period, a paroxyfm is in fome fhape renewed, which runs the fame courfc as before. This con- ftitutes what is called a R e m r tt e n t Fe v e r. 27.] When in thefe remittents the remiflion is consider- able, and the return of a new paroxyfm isdiftinfctly mark- ed by the fymptoms of a cold ftage at the beginning of it; fuch fevers retain fhictly the appellation of Re mitten is. But when it happen, as it does in certain cafes, that the remiflion is not conhderable, is perhaps without fweat, and thit the returning paroxyfm is not marked by the molt ufual Iymptoms of a cold ftage, but chiefly by the aggra- vation or Exacerbation of a hot ftage, the difeafe is called a Continued Fever. 28.] In fome cafes of continued fever, the remifhons and exacerbations are fo inconlklerablc as not to be eafily * Of the quotidian, tertian, and quartan intermittents there are many va- ll.; es and forms ; as the double tertian, 1-,-ja ing a ;.;iro.\-, :rn every day, with the alternate paroxysms similar to one another.

OF PHYSIC. 33 ©bfervcd or diftinguifhed; and this has led phyficians to imagine, that there is a fpecies of fever fubfifting for feve- ral days together, and fcemingly, confifting of one parox-' ylm only. This they have called a Continent Fever ; but, in a long courfe of practice, I have not had an op- portunity of obferviug fuch a fever. 29.] It is, however, to be obferved here, that the fevers of a continued form are to be diftinguifhed from one ano- ther ; and that, while fome of a very continued form do ftill belong to the fection of intermittents, there are others which, though ftill conhlling of feparate and repeated pa- roxyfms, yet as different from their caufes and circumftan- ces from intermittents, are to be diftinguifhed from the whole of thefe, and are more ftriflly to be called and con- fidered as Continued.* Such are molt of thofe which have been commonly fuppofed to be Continent; and thofe which by moft writers have been limply named Co x- tinued ; and which term I have employed as the title of a fection, to be diftinguifhed from that of I n t e r m i t t e n t. I fliall here add the marks by which, in pra8ice, thefe different continued fevers may be diftinguifhed from one another. Thofe fevers of a continued form, which, however, ftill belong to the fection of Intermittents, may be diftinguifh- ed by their having paiTed from an intermittent or remit- tent form, to that of a continued ; by their fhowing fome tendency to become intermittent, or at leaft remittent; by their being known to have been occafioned by marfh mi- afmata ; and for the moft part, by their having but one paroxyfm, or exacerbation and remiflion, in the courfe of twenty-four hours. On the other hand, Continued Fevers, to be more ftrict- ly fo called, may be diftinguifhed by their fhowing little tendency to become intermittent or remittent in any part of their courfe, and efpecially after the firft week of their continuance ; by their being occafioned by human contagi- on, at leaft by other caufes than the marfh miafmata; and * This passage i.~ very obscure : the author's meaning is, thit some conti- nued fevers put on the appearance of intermittents ; but being different, in some peculiar and material circumstances, from intermittents, are n0t to be classed with them.

In both cafes, the knowledge of the nature of the epidemic for the time prevailing, may have a great fhare in deter- mining the nature of the particular fever. 30.] With refpeel to the form, or Type of fevers, this further may be obferved, That the quartan, while it has the longeft interval, has at the fame time, the longeft and moft violent cold ftage ; but, upon the whole, the fhorteft paroxyfm: That the tertian, having a fhorter interval than the quartan, has at the fame time, a fhorter and lefs vio- lent cold ftage ; but a longer paroxyfm : And laftly, that the quotidian, with the fhorteft interval, has the leaft of a cold ftage, but the longeft paroxyfm. 31.] The type of fevers is fometimes changed in their courfe. When this happens, it is generally in the following manner : Both tertians and quartans change into quotidi- ans, quotidians into remittents, and thefe laft become often of the moft continued kind. In all thefe cafes, the fever has its paroxyfm protracted longer than ufual, before it changes into a type of more frequent repetition. 32.] From all this a prefumption arifes, that every fever confifts of repeated paroxyfm, differing from others chiefly in the circum'ftances and repetition of the paroxyfms ; and tlierefore, that it was allowable for us to take the paroxyfm of a pure intermittent as an example and model of the whole.

OF PHYSIC. 35 pretend to afcertain it in a manner that may remove every difficulty ; but I fhall endeavor to make an approach to- wards it, and fuch as I hope, may be of ufe in conducting the pracfife in this difeafe -. while at the fame time I hope to avoid feveral errors which have formerly prevailed pn this fubjccL 34.} As the hot ftage of fever is fo conftantly preceded fey a cold ftage, we prefume that the latter is the caufe of the former ; and therefore, that the caufe of the cold ftage is the caufe of all that follows in the courfe of the parox- yfm.-----See Boerh. Aph. 756. 35 ] To difcovcr the caufe of the cold ftage of fevers, we may obferve, that k is always preceded by ftrong marks of a general debility prevailing in the fyftem. The finall- nefs and wreaknefs of the pulfe, the palenefs and eoldnefs • of the extreme parts, with the fhrinking of the whole body, fufficiently ihow that the action of the heart and larger ar- teries is, for the time, extremely weakened. Together with this, the langour, inactvity, and debility of die animal mo- tions, the imperfect fenfations, the feeling of cold, while the body is truly warm, and fome other fymptoms, all fhew that the energy of the brain is, on this occafion, great- ly weakened > and I prefume, that as the weaknefs of the acVion of the heart can hardly be imputed to any other caufe, this weaknefs alio is a proof of the diminifhed ener- gy of the brain. 36.] I fhall hereafter endeavor to fhow,. that the moft noted of the remote caufes of fever, as contagion, miafma- ta, cold and fear, are of a fedative nature ; and therefore render it probable that a debility is induced. Likewife, when the paroxyfms of a fever have ceafed to Be repeated, they may again be renewed, and are moft commonly re- newed by the application of debilitating powers. And further, the debility which fiihfifts in the animal motions and other fmitt ions through die whole of fever, renders it pretty certain that fedative or debilitating powers * have been applied to the body. • A purge administered six cr seven days after the appearance of any pa- roxysm, has frequently occasioned a relapse, and is a practice that ought to be carefully avoided. I have generally found that purges given in the be^iu.- nin£ of th* disease, increase the di.lkulty of curing iu 35 PRACTICE 37.] It is therefore evident, that there are three ftates which always take place in fever: a ftate of debility, a ftate of cold, and a ftate of heat; and ss thefe three ftates regularly and conftantly fucceed each other in the order we have mentioned them, it is prefumed that they are in the feries of caufe and effect with refpeft. to one another. This we hold as matter of fact, even although we fhould not be able to explain in what manner, or by what mechanical means thefe ftates feverally produce each other. 38 J How the ftate of debility produces fome of the fymptons of the cold ftage, may perhaps be readily ex- plained ; but how it produces all of them, I cannot ex- plain otherwife than by referring the matter to a general law of the animal ceconomy, whereby it happens, tfat pow- ers which have a tendency to hurt and deftroy the fyftem, often excite fuch motions as are fuited to obviate the ef- fects of the noxious power. This is the vis medica- trix nature, fo famous in the fchools of phylic ; and it feems probable, that many of the motions excited in fever are the effects of this power. 39.] That the increafed action of the heart and arteries, which takes place in the hot ftage of fevers, is to be consi- dered as an effort of the vis medicatrix natures, has been long a common 6pinion among phyficians; and I am dif- pofed to affert, that fome part of the cold ftage may be imputed to the fam6 power. I judge fo, becaufe the cold ftage appears to be univerfally a means of producing the hot; becaufe cold, externally applied, has very often fi- milar effects; and more certainly ftill, becaufe it feems to be in proportion to the degree of tremor in the cold ftage, lhat the hot ftage proceeds more or lefs quickly to a ter- mination of the paroxyfm, and to a more compleat foluti- on and longer intermiflion. See 30. 40.] It is particularly obferved, that during the cold ftage of fever, there feems to be a fpafm induced every where on the extremities of the arteries, and more efpecially of thofe upon the furface of the body. This appears from the fuppreffion of all excretions, and from the fhrinking of the external parts; and although this may perhaps be im- puted in part to the weaker action of the heart in prjopel- ling the blood into the extreme veffels; yet? as thefe fy mp- OF PHYSIC. 57 toms often continue after the action of the heart is reftored, there is reafon to believe, that a fpafmoclic conftriction has taken place ; that it fublifts for fome time, and fupports the hot ftage ; for this ftagc ceafes with the flowing of the fweat, and the return of other excretions, which are marks of the relaxation of velfels formerly conftricted. Hoft- iM:i. Med. rat. Syftem. Tom. 4. P. 1. Sect. 1. Cop. 1. art. 4. 41.] The idea of fever, then, may be that a fpafm of the extreme veffels, however induced, proves an irritation to the heart and arteries; and that this continues till the fpafm is relaxed or overcome. There are many appearance; which fupport this opinion; and there is little doubt that a fpafm docs take place, which proves an irritation to the heart, and therefore may be confidcred as a principal pa it in the proximate caufe of fever. It will ftill, however, re- main a queftion, what is the caufe of this fpafm; whether it be directlv produced by the remote caufes of fever, or if it be only a part of the operation of the vis medicatrix naturae. 42.] I am dil'pofed to be of the latter opinion, becaufe in the first place, while it remains ftill certain that a debility lays the foundation'of fever, it is not obvious in what man- ner the debility produces the fpafm, and what feems to be its effect, the mcreafed action of the heart and arteries; and secondly, becaufe, in almoft all the cafes, in which an effort is made by the vis medicatrix natures, a cold fit aid a fpafm of the extreme veffels are almoft always the begin- nings of fuch an effort. SccGaub. Pathol. Med1cin.art.750. 43.] It is therefore prefumed, that fuch a cold fit and fpafm, at the beginning of fever, is a part of the operation of the vis medicatrix; but, at the fame time, it feems to me probable, that during the whole courfe of the fever, there is an atony fubfifting in the extreme veffels, and that the relaxation of the fpafin requires the reftoring of the tone and action of thefe. 44.] This it may be difficult to explain; but I think it may be afcertaincd as a fact, by the confideration of the fymptoms which take place, with refpect to the functions of the ftomach in fevers, fuch as the anorexia, naufea, arid vomiting. (14.J 38 PRACTICE From many circumftances it is fufBciently certain, that there is a confent between the ftomach and furface of the body: and in all cafes of the confent of diftant parts, it is prefumed to be by the connexion of the nervous fyftcm, and that the confent which appears, is between the icntient and moving fibres of the one part witfc thofe of the other, is fuch, that a certain condition prevailing in the one part, occafions a fimilar condition in the other. In die cafe of the ftomach and furface of the body, the confent particularly appears by the connexion which is ob- ferved between the ftate of the perforation, and the ftate of the appetite in healthy perfons; and if it may be prefum- ed that the appetite depends upon the ftate of tone in the mufcular fibres of the ftomach, it will follow, that the- connexion of appetite and perfpiration depends upon a confent between the mufcular fibres of the ftomach, and. the mufcular fibres of the extreme veffels, or of the organ of perfpiration, on the furface of the body. It is further in proof of the connexion between the ap- petite and perfpiration, and at the fame time of the cir- cumftances on which it depends, that cold applied to the furface of the body, when it does not flop perfpiration, but proves a ftimulus to it, is always a powerful means of exciting appetite. Having thus eftablifhed the connexion or confent men- tioned, we argue, that as the fymptoms of anorexia, nau- fea, and vomiting, in many cafes, manifeftly depend upon a ftate of debility or lofs of tone in the mufcular fibres of the ftomach; fb it may be prefumed, that thefe fymptoms, in the beginning of fever, depend upon an atony commu- nicated to the mufcular fibres of the ftomach, from the mufcular fibres of the extreme veffels on the furface of the body. That the debility of the ftomach which produces vo- miting in the beginning of fevers, actually depends upon an atony of the extreme veffels on the furface of the body, appears particularly from a fact obferved by Dr. Syden- ham. In the attack of the plague, a vomiting happens,. which prevents any medicine from remaining on the fto- mach; and Dr. Sydenham tells us, that •in fuch cafes he could not overcome this vomiting but by external means OF PHYSIC. 39 applied to produce a fweat; that is, to excite the action of the veffels on the furface of the body. The fame connexion between the ftate of the ftomach ^nd that of the extreme veffels on the furface of the body, appears from this alfo, that the vomiting, which fo fre- quently happens in the cold ftage of fevers, commonly ceafes upon the coming on of the hot, and very certainly upon any fweal's coming out (14.) It is indeed probable, that the vomiting in the cold ftage of fevers, is one of the means employed by nature for reftoring the determination to the furface of the body; and it is a circumftance afford- ing proof, both of this, and of the general connexion be- tween the ftomach and furface of the body, that emetics thrown into the ftomach, and operating there, in the time of the cold ftage, commonly put an end to it, and bring on the hot ftage. It alfo affords a proof of the fame connexion, that cold Water, taken into the ftomach produces an increafe of heat on the furface of the body, and is very often a convenient and effectual means of producing fweat. From the whole we have now faid on this fubject, I think it is fufficiently probable, that the fymptoms of ano- rexia, naufea, and vomiting, depend'upon, and are a proof of, an atony fubfifting in the extreme veffels on the furface of the body; and that this atony therefore, now afcertained as a matter of fact, may be confidered as a principal circumftance in the proximate caufe of fever. 45.] This atony * we fuppofe to depend upon a dimi- nution of the energy of the brain; and that this diminution takes place in fevers, we conclude, not only from the de- bility prevailing in fo many of the funftions of the body, mentioned above (35.) but particularly from fymptoms which are peculiar to the brain itfelf. Delirium is a fre- quent fymptom of fever; and as from the phyfiology and pathology we learn that this fymptom commonly depends upon fome inequalitv in the excitement of the brain or in- tellectual organ; we hence conclude, that, in- fever, it denotes fome diminution in the energy of the brain. De- lirium, indeed, feems often to depend upon an increafed « * The reader will perc*ive, that the whole of the doctrine delivered in thic chapter is hypothetical. 40 PRACTICE impetus of the blood, in the veffels of the brain, and therefore attends phrenitis. It-frequently appears alfo in the hot fiage of fevers, accompanied with a headach and throbbing of the temples. But as the impetus of the blood in the veffels of tire head is often coniiderably increafed by cxercife, external heat, pafhons, and other caufes, without occafioning any delirium ; fo, fuppo- fmg that the fame impetus, in the caufe of fever, pro- duces delirium, the reafon muft be, that at the fame time, there is fome caufe which diminifhes the energy of the brain, and prevents a free ..communication between the parts concerned in the intellectual functions. Upon the fame principles alfo, I fuppofe there is another Ipecies of delirium, depending more entirely on the diminifhed ener- gy of the brain, and which may therefore arife, when there is no unufual incrcafe of the impetus of the blood in the veffels of the brain. Such feems to be the delirium oc- curring at the beginning of the cold ftagc of fevers, or in the hot ftagc of fuch fevers as fhow ftrong marks of debi- lity in thcwhole fyftem. 46.] Upon the whole, our doctrine of fever is explicitly this. The remote caufe-? (36.) are certain fedative powers applied to the nervous fyftem, which diminifhing the ener- gy of the brain, thereby produce a debility in the whole of the functions, (3^) and particularly in the action of the ex- treme veffels, (43. 44.) Suchy however, is, at the fame time, the nature of the animal ceconomy, (38.) that this debility proves an indirect ftimulus to the fanguifcrous fyftem ; whence, by the intervention of the cold ftage, and fpafm connected with it, (39. 40.) the action of the heart and lar- ger arteries is increafed, (40.) and continues fo (41.) till it has had the effect of rcftoring the energy of the brain, of extending this energy to the extreme veffels, of rcftoring therefore their action, and thereby efpecially overcoming the fpafm affecting them ; upon the removing of which, the excretion of fweat, and other marks of the relaxation of excrctories, take place. 47.] This doctrine will, as I fuppofe, fefve to explain not only the nature of fever in general, but alfo the vari- ous cafes of it which occur. Before proceeding, however, to this, it may be proper to point out the opinions, and as OF PHYSIC 41 I apprehend, the miftakes, which have formerly prevailed on this fubject. 48.] It has been fuppofed, that a lentor or vifcidity pre- vailing m the mafs of blood, and ftagnatingin the extreme veffels, is the caufe of the cold ftage of fevers and its con- fequences. But there is no evidence of any fuch vifcidity prcvioufly fubfifting in the fluids; and as it is very impro- bable that fuch a ftate of them can be very quickly pro- duced, fo the fuddennefs with which paroxyfms come on renders it more likely that, the phenomena depend upon fome caufe aEing upon the nervous fyftem, or the prima- ry moving powers of the animal economy. See Van Swieten apud Boerh. Aph.. 755. 49.] Another opinion, which has been almoft univer- fally received, is, that a noxious matter introduced into, or generated in, the body, is the proximate caufe of fe- ver; and that the increafed a&ion of the heart and arteries, which forms fo great a part of the difeafe, is an effort of the vis medicatrix naturce to expel this morbific matter ; and particularly to change or concoait, foas to render it either altogether innocent, or at leaft, fit for being more eafily thrown out of the body. This doctrine, however, although of as great antiquity as any of the records ofphy- hc now remaining, and although it has been received by almoft every fchool of medicine, yet appears to me to reft upon a very uncertain foundation. There are fevers pro- duced by cold, fear, and other caufes, accompanied with all the effential circumftances of fever, and terminating by fweat; but, at the fame time, without any evidence or fufpicion of morbific matter. There have been fevers fuddenly cured by a hemorrha- gy, fo moderate as could not carry out any confiderable portion of a matter diffufed over the whole mafs of blood; nor can we conceive how the morbific matter could becol- leded or determined to pafs off by fuch an outlet as in that cafe is opened. Even fuppofing a morbific matter were prefent, there is no explanation given, in what manner the concoaion of it is performed ; nor is it fhown that any fuch change does in fa& take place. In certain cafes, it is indeed evident, that a noxious matter is introduced into the body, and proves 42 PRAGTIGK the caufe of fever; but, even in thefe cafes, it appears that the noxious matter is thrown out again, without hav- ing fuffered any change; that the fever often terminates before the matter is expelled; and that, upon many occa- fions, without waiting the fuppofed time of concoction, the fever can be cured, and that by remedies which do not feem to operate upon the fluids, or to produce any eva- cuation. 50.] While we thus reafon againft the notion of fever heing an effort of nature, for concoaing and expelling a morbific matter; I by no means intend to deny that the caufe of fever frequently operates upon the fluids, and par- ticularly produces a putrelccnt ftate of them. I acknow- ledge that this is frequently the cafe; but, at the fame time, I maintain, that fuch a change of the fluids is not commonly the caufe of fever; that very often it is an ef- fea only; and that there is no reafon to believe the termi- nation of the fever to depend upon the expulfion of the putrid matter. 51.] Another opinion which has prevailed^ remains ftill to be mentioned. In intermittent fevers, a great quantity of bile is commonly thrown out by vomiting ; and this is fo Frequently the cafe, that many have fuppofed an unufual quantity of bile, and perhaps a peculiar quality of it, to be the caufe of intermittent fevers. This, however, does not appear to be well founded. Vomiting, by whatever means excited, if too often repeated, with violent {training, feems to be .powerful in emulging the biliary du6ts, and com- monly throws out a great deal of bile. This will happen efpecially in the cafe of intermittent fevers. For as, in the ftate of debility and cold ftagc of thefe fevers, the blood is not propeller! in the ufual quantity into the extreme vef- fels, and particularly into thofe on* the furface of the body, but is accumulated in the veffels of the internal parts, and particularly in the vena portarum ; fo this may occafion a more copious fecretion of bile. Thefe confiderations will, in fome meafure, account for the appearance of an unufal quantity of bile in intermittent fevers; but the circumftance which cheifiy occalions the appearance of bile in thefe cafes, is the influence of warm climates and feafons. Thefe feldom fail to produce a ftate OF PHYSIC. *2 of die human body, in which the bile is difpofed to pals off, by its fecretories, in greater quantity than ufual; and per- haps alfo changed in its quality, as appears from the difeafe of cholera, which fo frequently occurs in warm feafons. At the fame time, this difeafe occurs often without fever; and we fhall hereafter render it fufticiently probable, that intermittent fevers, for the moft part, arife from another caufe, that is, from marfh effluvia ; while on the other hand, there is no evidence of their arifing from the ftate of the bile alone. The marfh effluvia however, commonly ope- rate moft powerfully in the fame feafon that produce* the change of and redundance of the bile; and therefore confix dering the vomiting, and other circumftances of the intermit- tent fevers which here concur, it is not furprifmg that autum- nal intermittents are fo often attended with effufionsof bile. This view of the fubject does not lead us to confider the ftate of the bile as the caufe of intermittents, but merely as a circumftance accidently concurring with them, from the ftate of the feafon in which they arife. What attention this requires in the conduct, of die difeafe, I fhali confider hereafter. 52.] From this view of the principal hypothecs which have hitherto been maintained with refpea to the proximate caufe of fever, it will appear, that fevers do not arife from changes in the ftate of the fluids; but that, on the contrary, almoft the whole of the phenomena of fevers lead us to be- lieve, that they chiefly depend upon changes in the ftate of the moving powers of the animal fyftem. Tho' we mould not be able to explain all the circumftances of the difeafe, it is at leaft of fome advantage to be led into the proper train of inveftigation. I have attempted to purfue it; and fhall now endeavour to apply the dodrine already delivered, towards explaining the diverfity of fevers. CHAP. III. ©f tit Difference of jFeuer& ami itft'Cautfeff* 53.] A O afcertain the difference of fevers, I think itne, ceffary to obferve; in the firft place; that every fever of 44 PRACTICE more than one day's duration, confifts of repeated, and in fome meafure feparate paroxyfms; and that the difference of fevers taken notice of above (from 25. to 30.) appears to confift in the different ftate of paroxyfms, and in the differ- ent circumftances of their repetition. 54.] That fevers generally confift of diftina,and in fome meafure feparately repeated paroxyfms, I have alledged above to be a matter of fact; but 1 fhall here endeavor to confirm it, by afligning the caufe. 55.] In every fever, in which we can diftincTly obferve any number of feparate paroxyfms, we conftantly find that each paroxyfm is finifhed in lefs than twenty-four hours ; but as I cannot perceive any thing in the caufe of fevers determining to this, I muft prefume it to depend on fome general law * of the animal economy. Such a law feems to be that which fubjeas the economy, in many refpects, to a diurnal revolution. Whether this depends upon the ori- ginal conformation of the body, or upon certain powers conftantly applied to it, and inducing a habit, I cannot pofi- tively determine; but the returns of fleep and watching, of appetites and excretions, and the changes which regular- ly occur in the ftate of the pulfe, fhow fufticiently, that in the human body a diurnal revolution takes place. 56.] It is this diurnal revolution which, I fuppofe deter- mines the duration of the paroxyfms of fevers; and the conftant and univerfal limitation-of thefe paroxyfms, (as obferved in 55.) while no other caufe of it can be alligned, renders it fufticiently probable, that their duration depends upon, and is determined by, the revolution mentioned. And that thefe paroxyfms are conneaed with that diurnal revolution, appears further from this, that though the in- tervals of paroxyfms are different in different cafes, yet the times of the acceftion of paroxyfms are generally fixed to one time of the day; fo that Quotidians come on in the morning, Tertians at noon, and Quartans in the afternoon. 57.] It remains to be remarked, that as Quartans and Tertians are apt to become Quotidians, thefe to pafs into the ftate of Remittents, and thefe laft to become Continu- • The reader will find entertainment in admiring the ingenuity of the au- thor, in contriving several articles for maintaining his doctrine. Or.c hypo- thesis piled on the top of another, almost without end, O F P H Y S I C. 45 eel; and that, even in the Continued form, daily ex- acerbations and remiftions are generally to be obferved ; fo all this fhows fo much the power of diurnal revolution, that when, in certain cafes, the daily exacerbations and re- miifions are with difficulty diftinguifhed, we may ftill pre- fume, that the general tendency of the economy prevails, that the difeafe ftill confifts of repeated paroxyfms, and, upon the whole, that there is no fuch difeafe as that which the fchools have called a Continent Fever. I expea that this doaHne will be confirmed by what I fhall fay here- after, concerning the periodical movements obferved in continued fever. 58.] It being thus proved, that every fever, of more than one day's duration, confifts of repeated paroxyfms; we, in the next place, remark, that the repetition of paroxyfms depends upon the circumftances of die paroxyfms which have already taken place. From what was obferved (in 30* and 31.) it appears, that the longer paroxyfms are pro- traaed, they are the fooner repeated ; and therefore, that the caufe of the frequent repetition is to be fought for in the caufe of the protraction of paroxyfms. 59.] Agreeably to what is laid down in 46. and to the opinion of moft phyficians, I fuppofe, that in every fever there is a power applied to the body, which has a tenden- cy to hurt and deftroy it, and produces in it certain moti- ons which deviate from the natural ftate ; and at the fame time, in every fever which has its full courfe, I fuppofe, that in confequence of the conftitution of the animal eco- nomy, there are certain motions excited, which have a ten- dency to obviate the effeas of the noxious power, or to correa and remove them. Both thefe kinds of motion are confidered as conftituting the difeafe. But the former is perhaps ftriaiy the morbid ftate, while the latter is to be confidered as the operation of the vis me- dicatrix natures of falutary tendency, and which I fhall hereafter call the reaction of the fyftem. 60.] Upon the fuppofition that thefe two ftates take place in every paroxyfm of fever, it will appear to be chief- ly in the time of the hot ftage that the reaaion operates in removing the morbid ftate; and therefore as this operation fucceeds more or lefs quickly, the hot ftage of paroxyfms 46 PRACTICE will be fhorter or longer. But as the length of paroxyfm depends chiefly upon the duration of the hot ftage, fo the longer duration of this and of paroxyfms, muft be owing cither to the obftinacy of refiftance in the morbid ftate, or to the weaknefs of the falutary reaction ; and it is proba- ble that fometimes the one, and fometimes the otlier of thefe circumftances takes place. 61.] It feems to be only by the ftate of the fpafm, that we can judge of the refiftance of the morbid ftate of fever- and with refpea to this fpafm I obferve, that either the caufe exciting it may be different in different cafes; or, though the caufe fhould be the fame in different perfons, the different degree of irritability, in each may give occa- fion to a greater or letter degree of fpafm; and therefore, the reaaion in fever being given, the continuance of the hot ftage, and of the whole paroxyfm, may be longer or fhorter, according to the degree of fpafm that has been formed. 62.] One caufe of the obftinacy of fpafm in fevers may be clearly perceived. In inflammatory difeafes, there is a diathefis phlogiftica prevailing in the body, and this dia-- thefis we fuppofe to confift in an increafed tone of the whole arterial fyftem. When, therefore, this diathefis ac- companies fever, as it fometimes does, it may be fuppo- fed to give occafion to the febrile fpafm's being formed more ftrongly, and thereby to produce more protraaed paroxyfms. Accordingly we find, that all inflammatory fevers are of the continued kind; and that all the caufes of the diathefis phlogiftica have a tendency to change inter- mittent into continued fevers. Continued fevers, then, being often attended with the diathefis phlogiftica, we con- clude, that, in many cafes, this is the caufe of their conti- nued form. 63.] In many fevers, however, there is no evidence of any diathefis phlogiftica being prefent, nor of any other caufe of more conhderable fpafm; and, in fuch cafes, therefore, we muft impute the protraction of paroxvfms and the continued form of the fever, to the weaknefs cf reaaion. That this caufe takes place, we conclude from hence, that, in many cafes of fever, wherein the feparate paroxyfms are the longeft protraaed; and the- moft diffi- OF PHYSIC. 47 cultly obferved, we find the moft confiderable fymptoms of a general debility : and therefore we infer, that, in fuch cafes, the protracted paroxyfms, and continued form, de- pend upon a weaker reaaion; owing either to the caufes of debility applied having been of a more powerful kind, or from circumftances of the patient's conftitution favour- ing their operation. 64-.]-Upon thefe principles we make a ftep towards ex- plaining in general, with fome probability, the difference of fevers; but muft own, that there is much doubt and dif- ficulty in applying the do£trine to particular cafes. It ap- plies tolerably well to explain the different ftates of inter- mittents, as they arc more purely fuch, or as they ap- proach more and more to the continued form: But feve- ral difficulties ftill remain with refpea to many circumftan- ces of intermittents; and more ftill with refpea to the dif- ference of thofe continued fevers, which we have diftin- guifhed in our Nofology as different from intermittents, and as more efpeciallv entitled to the appellation of Conti- nued, (fee Syn. Nof. Meth. P. V. Ch. I. Sea. II.) and explained more fully above. 6$.] From the view given (63 and 64.) of the caufes of the protraaion of paroxyfms, and therefore of the form of Continued fevers, ftriaiy fo called, it feems probable, that the remote caufes of thefe operate by occafioning ei- ther a phlogiltic diathefis, or a weaker reaaion; for we can obferve, that the moft obvious difference of continued fe- vers depends upon the prevalence of one or other of thefe ftates. 66.] Continued fevers have been accounted of great di- verfity ; but phyficians have not been fuccefsful in mark- ing thefe differences, or in reducing them to any general heads. The diftinaions made by the ancients are not well underftood; and, fo far as either they or the modern nofo- logifts have diftinguifhed continued fevers by a difference of duration, their diftinaions are not well founded, and do not apply in fuch a manner as to be of any ufe. We think it agreeable to obfervation, and to the principles above laid down, (63. 64.) to diftinguifh continued fevers ac- cording as they fhow either an inflammatory irritation or a weaker reaaion. 48 PRACTICE 6y.] This diftinaion is the fame with that of fevers into the Inflammatory and Nervous; the diftinfction at prefent moft generally received in Britain. To the firft, as a genust I have given the name of Synochus; to the fccond, that of Typhus; and little ftudious whether thefe names beauthorifed by the ancient ufe of the fame terms, I depend upon their being underftood by the charaaers * annexed to them in our Nofology, which I apprehend to be founded on obfervation. 68.] By thefe characters I think continued fevers may in practice be diftinguifhed; and if that be the cafe, the principles above laid down will be confirmed. 69. J Befide thefe differences of continued fever, now mentioned, I am not certain of having obferved any other that can be confidered as fundamental. But the moft com- mon form of continued fevers, in this climate, feems to be a combination of thefe two genera; and I have therefore given fuch a genus a place in our Nofology, under the ti- tle of Synochus. At the fame time, I think that the limits between the Synochus and Typhus will be with difficulty aftigned; and I am difpofed to believe, that the Synochus arifes from the fame caufes as the Typhus, and is therefore only a variety of it. 70.] The Typhus feems to be a genus comprehending feveral fpecies. Thefe, however, are not yet well afcer- tained by obfervation; and in the mean time we can per- ceive that many of the different cafes obferved, do not im- ply any fpecific difference, but feem to be merely varieties arifing from a different degree of power in the caufe, from different circumftances of the climate or feafon in which they happen, or from different circumftances in the confti- tution of the perfons affiled. 71.] Some of the effects arifing from thefe circumftan- ces require to be particularly explained. One is, an unufual quantity of bile appearing in the courfe of the difeafe. This abundance of bile may poffibly attend fome continued levers, ftrictly fo called ; but, for the reafons above explained, it more commonly attends * These characters are, Synocha. Calorplurimumauctus ; pulsus frequent, validus, et durus ; urina rubra ; sensorii functiones plurimum turbats i vires multum imminutse. OF PHYSIC. 43 intermittents, and we believe, it might have been enume- rated (29.) among the marks diftinguifhingthe latter kind of fevers from the former. But though an unufal quantity of bile fhould appear with continued fevers, it is confider- ed in this cafe, as in that of intermittents, to be a coinci- dence only, owing to the ftate of the feafon, and produc- ing no different fpecies or fundamental diftinaion, but merely a variety of the difeafe. I think it proper to ob- ferve here, that it is probable that the moft part of the con- tinued fevers named Bilious have been truly fuch as belong to the feaion of Intermktents. 72.] Another effea of the circumftances occafionally va- rying the appearance of typhus, is a putrefcent ftate of the fluids. The ancients, and likewife the moderns, who are in general much difpofed to follow the former, have def- tinguifhed fevers, as putrid, and non putrid : but the noti- ons of the ancients, on this fubject, were not fufticiently correa to deferve much notice ; and it is only of late that the matter has been more accurately obferved, and better explained. From the diffolved ftate of the blood, as it prefents itfelf when drawn out of the veins, or as it appears from the red blood's being difpofed to be effufed and run off by various outlets, and from feveral other fymptoms to be hereafter mentioned, IJaave now no doubt, how much foever it has been difputed by fome ingenious men, that a putrefcency of the fluids, to a certain degree, does really take place in many cafes of fever. This putrefcency, however, often attends intermittent, as well as continued fevers, and of the continued kind, both the fynochus and typhus, and all of them in very different degrees; fo that whatever attention it may deferve in praaice, there is no fixing fuch limits to it as to admit of eftabhfhing a fpecies under the title of Putrid. ' 73.] Befide differing by the circumftances already men- tioned, fevers differ alio by their being accompanied with fymptoms which belong to difeafes of the other orders of pyrexiae. This fometimes happens in fuch a manner, as to render it difficult to determine which of the two is the pri- mary difeafe. Commonly, however, it may be afcertained by the knowledge of the remote caufe. and the prevailing Vwj.. t. • G SO P~R A C T I C IE epidemic, or by obferving the feries and fucccflion of fymptoms. 74.] Moft of our fyftems of phyfi-c have marked, as a primary one, a fpecies of fever under the title of Hectic -; but as it is defcribed, I have never feen it as a primary dif- eafe. I have conftantly found it as a fymptom of fome to- pical affeaion, moft commonly of an internal fuppuration; and as fuch it fhall be confidered in another place. 75.] The diftinaion of the feveral cafes of intermittent fever I have not profecuted here; both becaufe we can- not aflign the caufes of the differences which appear ; and becaufe J apprehend that the differences which in fact oc- cur may be readily understood from-what is laid above (25. 26. and 27.) and more -fully from our Methodical Nofology, Ch. I. Sea. I. CHAP. IV. SDf tit Eemote Cause of jFetoer, 76.] XXS fever has been held to confift chiefly in an in- creafed aaion of the heart and arteries, phyficians have fup- pofed its remote caufes to be certain dirc6t ftimulants fitted to produce, this increafed attion. In many cafes, however, there is no evidence of fuch ftimulants being applied ; and in thofe in which they are applied, they either .produce on- ly a temporary frequency of the pulfe, which cannot be confidered as a difeafe ; or, if they do produce a perma- nent febrile ftate, it is by the intervention of a topical in- flammation, which produces a difeafe different from what is ftriaiy called fever. (8.) 77.] Thatdirea ftimulants are the remote caufes of fe- ver, feems farther improbable ; becaufe the fuppofition does not account for the phenomena attending the accefli- on of fevers, and becaufe other remote caufes can with greater certainty be affigned. 78.] As fevers are fo generally epidemic, it is probable, that fome matter floating in the atmofphere, and applied to the bodies of men, ought to be confidered as the remote caufe of fevers : And thefe matters prefent in the atmof- OF PHYSIC 51 phere, and thus aaing upon men, may be confidered either as Contagions, that is, effluvia arifirfg direaiy or origi- nally from the body of a man under a particular difeafe, and exciting the fame kind of difeafe in the body of the perfon to whom they are applied; or Miasmata, that is, effluvia arifing from other fubftances than the bodies of men, producing a difeafe in the perfon to whom they are applied. 79.] Contagions have been fuppofed to be of great va- riety ; and it is pofiible this may be the cafe ; but that they truly are fo, docs not appear clearly from any thing we know at prefent. The genera and fpecies of contagious difeafes, of the Pyrexiae at prefent known, are in number not very great. They chiefly belong to the order of Fevers, to that of Exanthemata, or that of Profluvia. Whether there be any belonging to the order of Phlegmafise, is doubtful; and though there fhould, it will not much in- creafe the number of contagious pyrexiae. Of the conta- gious exanthemata and profluvia, the number of fpecies is nearly afcertained ; and each of them is fo far of a deter- mined nature, that though they have now been obferved and diftinguifhed for many ages, and in many different parts of the world, they have been always found to retain the fame general charaaer, and to differ only irr circumftan- ces, that may be imputed to feafon, climate, and other ex- ternal caufes, or to die peculiar conftitutions of the feveral pcrfons affected. It feems, therefore, probable, that in each of thefe fpecies, the contagion is of one fpecific na- ture ; and that the number of contagious exanthemata or profluvia is hardly greater than the number of fpecies enumerated in. the fyftems of nofology. 80.] If, while the contagious exanthemata and profluvia are thus limited, we fhould fuppofe the contagious pyrexia to be ftill of great and unlimited variety, it muft be with refpea to the genera and fpecies of continued fevers. But if I be right in limiting, as I have done, the genera of thefe fevers (6j.—70.) it will appear likely that the contagions which produce them are not of great variety; and this will be much confirmed, if we can render it probable that there is one principal, perhaps one common, fource of fuch con* fcagior^ 32 PRACTICE 81.] To thispurpofe it is how well knownt of its being in general a caufe of fevers, nor of its bein^ very univerfally the caufe of intermittent fevers, in all their different forms. The fimilarity of the climate, feafon, and foil, in the different countries in which intermittents arife, and the fimilaritv of the difeafes, though arifing in different regions, concur in proving, that there is one common caufe of thefe cufeafes, and that this is the marfh miafma. What is the particular nature of this miafma, we know not; nor do we certainly know whether or not it differs in kind; but it is probable that it does not; and that it varies only in the degree of its power, or perhaps as to its quan- tity, in a uiven fpace. 85.J It lias bc.c;i now rendered probable, that the remote caufes of fevers (8.) are chiefly Contagions or Miafmata, and neither of them of great variety. Wc have fuppofed that miafmata are the catife of intermittents, and contagions the caufe of continued fevers, ftridly fo named; but we cannot with propriety employ thefe general terms. For, as the caufe of continued fevers may arife from fomites, and may, in fuch cafes, be celled a Miafma; and as other miafmata alfo may produce contagious difeafes; it will be proper to diflinguifh the caufes of fevers, by ufmg the terms Human or Marsh Effluvia, rather than the general ones of Contagion Miafma. 86.] To render ourdoarine of fever confiftent and com- pile, it is neceffary to add here, that thofe remote caufes of fever, human and marfh effluvia, feem to be of a debi- litating or fedative quality. They arifc from a putrefcent matter. Their produttion is favoured, and their power in- creafed, by circumftances which favour putrefaction; and they often prove putrefactive ferments with refpect to the ^iimal fluids. As putrid matter, therefore, is always with refpea to animal bodies, a powerful fedative, fo it can hard- ly be doubted, that human and marfh effluvia are of the fame quality: and it is confirmed by this, that the debility which is always induced, feems to be in proportion to the other marks that appear of the power of thofe caufes. 87.] Though we have endeavoured to (how that fevers S4 PRACTICE generally arife from marfh or human effluvia, we cannot,, with any certainty, exclude fome other remote caufes, which are commonly fuppofed to have at leaft a fhare in producing thofe difeafes. And I proceed, therefore, to enquire concerning thefe caufes; the firft of which that merits attention, is the power of cold applied to-the human body. 88.] The operation of cold on a living body, is fo differ- ent in different circumftances, as to be of difficult explana- tion; it is here, therefore, attempted with fome diffidence. The power of cold may be confidered as abfolute or relative. The absolute power is that by which it can diminifh the temperature of the body to which it is applied. And thus,' * if the natural temperature of the human body is, as we fup- pofe it to be, that of 98 degrees of Farenheit's thermome- ter;* every degree of temperature lefs.than that, may be confidered as cold with refpea to the human body; and, in proportion to its degree, will havea tendency to diminifh the temperature of the body. But as the living human bo- dy has in itfelf a power of generating heat, fo it can fuftain its own proper heat to the degree above mentioned, though furrounded by air or other bodies of a lower temperature than itfelf; and it appears from obfervation, that, in this climate, air, or other bodies applied to the living man, do not diminifh die temperature of his body, unlefs the tem- perature of the bodies applied be below 62 degrees. From hence it appears, that the abfolute power of cold in this climate, does not aa upon the living human body, mile's the cold applied be below the degree juft now mentioned. It appears alfo that the human body's being furrounded by air of alower temperature than itfelf, is neceffary to its being retained in its proper temperature of 98 degrees: for, in this climate, every temperature of the air above 62 de- grees, applied to the human body, though ftill of a lower temperature than itfelf, is found to increafe the heat of it. And from all this it appears, that the abfolute power of cold with refpea to the human body, is very different from what it is with refpea to inanimate bodies. * In every instance of our mentioning decrees of heat or cold, we sha.'A roention them by the degrees in Farenheit's scale ; and the'exp re-iion of higher or lower shall always be according to that scale. OF PHYSIC. 55 89.] The relative power of cold with refpea to the liv- ing human body, is that power by which it produces a fen- fation of cold in it; and with refpea to this, it is agreeable to the general principle of fenfation, that the fenfation pro- duced, is not in proportion to the abfolute force of impref- hon, but according as the new imprefhon is ftronger or weaker than that which had been applied immediately be- fore. Accordingly, with refpect to temperature, the fen- fation produced by any degree of this, depends upon the temperature to which the body had been immediately be- fore expofed; fo that whatever is higher than this feels warm, and whatever is lower than it, feels cold; and it will therefore happen that the oppofite fenfations of heat and cold may on different occafions arife from the fame tem- perature, as marked by the thermometer. With refpea to this, however, it is to be obferved, that though every change of temperature gives a fenfation of cold or heat as it is lower or higher than the temperature applied immediately before, the fenfation produced is, in different cafes, of different duration. If the temperature at any time applied is under 62 degrees, every increafe of temperature applied will give a fenfation of heat; but if the increafe of temperature does not arife to 62 degrees, the fenfation produced will not continue long, but be foon changed to a fenfation of cold. In like manner, any tem- perature, applied to the human body, lower than that of the body itfelf, gives a fenfation of cold; but if the tem- perature applied does not go below 62 degrees, the fenfa- tion of cold will not continue long, but be foon changed to a fenfation of heat. It will appear hereafter, that the effeas of the fenfation of cold will be very different, according as it is more per- manent or tranfitory. 90.] Having thus explained the operation of cold, as ab- folute or relative, with refpea to the human body, I pro- ceed to mention the general effeas of cold upon it. 1. Cold, in certain circumftances, has manifeftly a seda- tive power. It can extinguifh the vital principle entirely, either in particular parts, or in the whole body ; and con- fidering how much the vital principle of animals depend* upon heat, it cannot be doubted that the power of cold is always more or lefs directly fedative. 58 PRACTICE This effea may be faid to take place from every degree of abfolute cold ; 2nd when the heat of the body has upon any oecafion been preternaturally increafed, every lower temperature may be ufeful in diminifhing the aaivity of, the fyftem ; but it cannot diminifh the natural vigor of thfc tital principle, till the cold applied is under 62 degrees ; nor even then will it have this ellect, unlefs the cold applied be of an intenfe degree, or be applied for fome length of time to a large portion of the body. 2. It is equally manifeft, that in certain circumftances, cold proves a stimulus to the living body, and particularly to the fanguiferous fyftem. It is probable, that this effea takes place in every cafe, in which the temperature applied produces a fenfation of cold; and this, therefore, as depending entirely on the re- lative power of cold, will be in proportion to the change of temperature that takes place. It appears to me probable, that every change .of tempe- rature, from a higher to a lower degree, will prove more or lefs ftimulant; excepting when the cold applied is {"o intenfe, as immediately to extinguifh the vital principle in the part. 3. Befide the fedative and ftimulant powers of cold, it is manifeftlv alfo a powerful astringent, caufmga contraction of the veffels on the furface of the body, and thereby pro- ducing a palenefs of the fkin, and a fuppreffion of perfpi- ration ; and it feems to have funilar effeas when applied to internal parts. It is like wife probable, that this con- ftriaion, as it takes place efpecially in confequence of the fenfibility of the parts to which the cold is applied, will in fome meafure be communicated to other parts of the bo- dy ; and that thereby the application of cold proves a tonic power with refpea to the whole fyftem. Thefe effeas of tonic and aftringent power feem to take place both from the abfolute and relative power of cold ; and therefore every application of it, which gives a fenfa- tion of cold, is in its firft effect, both aftringent and ftimu- luiU, though the former may be often prevented from being cither confiderable or permanent, when the latter immedi- ately takes p-lace. 01.] It will be obvious, that thefe feveral effeas of cold OF P II Y'S I c. s: cannot all take place at the fame time, but may in fuccef- fion be varioufly combined. The ftimulant power taking place obviates the effeas, at leaft the permanency of the effeas, that might otherwife have arifen from the fedative power. That the fame ftimulant power prevents thefe from the aftringent, I have faid above ; but the ftimulant and to- nic powers of cold are commonly, perhaps always, con- joined. 92.] Thefe general effeas of cold now pointed out are fometimes falutary, frequently morbid; but it is the latter only I am to confider here, and they feem to be chiefly the following. 1. A general inflammatory difpofition of the fyftem, which is commonly accompanied with Rheumatifm, or o- ther Phlegmafiae. 2. The fame inflammatory difpofition accompanied with Catarrh. 3. A Gangrene of particular parts. 4. A Palfy of a tingle member. 5. A Fever, or Fever ftriaiy fo called (8) which it of- ten produces by its own power alone, but more common- ly it is only an exciting caufe of fever by concurring with the operation of human or marfh effluvia. 93.] Cold is often applied to the human body without producing any of thefe morbid effeas, and it is difficult to determine in what circumftances it. efpecially operates in producing them. It appears to me, that the morbid effeas of cold depend partly upon certain circumftances of the cold itfelf, and partly on certain circumftances of the per- fon to whom it is applied. 94.] The circumftances of the cold applied, which feem to give it effea, are, 1. The intenfity or degree of the cold: 2. The length of time during which it is applied ; 3. The degree of moifture at the fame time accompanying it; 4. Its being applied by a wind or current of air; 5. Its be- ing a viciflimde, or fudden and confiderable change of temperature, from heat to cold. 95-] The circumftances of perfons rendering them more liable to be affiled by cold, feem to be, 1.

One part of the body being expofed to cold, while the reft is kept in its ufual-or a greater warmth. 96.] The power of ihefe circumftances (95) is demon- ftratcd by the circumftances enabling perfons to rciift cold. Thefe are a certain vigour of conftitution, cxercife of the body, the pretence of attive paffions, and the ufe of cor- dials. Befides thefe, there are other circumftances which, by a different operation, enable perfons to refift cold a6ting as a fenfation ; fuch as, paffions engaging a clofe attention to one object, the ufe of narcotics, and that ftate of the body in which fenfibility is greatly diminifhed, as in maniacs. To all which is to be added, the power of habit with ref- pea to thofe parts of-the body to which cold is more con- ftantly applied, which both diminifhes fenfibility and in- crcafes the power of the aaivity generating heat. 97.]Befide cold, there are omer powers-that feem to be remote caufes of fever; fuch as fear,intemperance in drink- ing, excefs in venery, and other circumftances, which evi- dently weaken the fyftem. But whether any of thefe feda- tive powers be alone the remote caufe of fever, or if they only operate either as concurring with the operation of marfh or human effluvia, or as giving»an opportunity to the operation of cold, are queftions not to be pofitively anfwered : they may poffibly of thcmfelves produce fever, but moft frequently they operate as concurring in one or other of the ways above mentioned. 98.] Having now mentioned the chief of the remote caufes of fevers, it may be further obferved, that thefe will arife more or lefs readily, according as miafmata and con- tagions are more or lefs prevailing or powerful, or as thefe are more or lefs favored by the concurrence of coldand other fedative powers. OF PHYS I-a >y CHAP. V. £Df t&e prognosis of j?et)crsr. Q9-}x\.S fevers (by 60.) confift of both morbid, and fa- lutary motions and fymptoms, the tendency of the-difeafe to a happy or fatal iffue,. or the prognoftic in fevers, has been eftablifhed by marking the prevalence of the morbid or of the falutary fymptoms ; and it might be properly fo eftablifhed, if we could certainly diltinguifh between the one and the other of thefe kind of fymptoms : but the ope- ration of the reaaion, or falutary efforts of nature in curing fevers, is ftill involved in fo much obfeurity, that I cannot explain the fevcral fymptoms of it fo clearly as to apply them to^ the cftabiifhing prognoftics; and this, I think, may be done better, by marking the morbid fymptoms which fhew the tendency to death in fevers. 100.] This plan of the prognoftics in fevers muft pro- ceed upon our knowledge of the caufes of death in general and in fevers more particularly. The caufes of death, in general,,arc either direa or in- dirca, The fir ft are thofe which dircaiy attack and deftroy the vital principle, as lodged in the nervous fyftem; or deftroy the organization of the brain immediately ncceffary to the action of that principle. The fecond,. or the indirea caufes of death, are thofe which interrupt fuch funaions as are ncceffary to the cir- culation of the blood, and thereby neceffary to the due continuance and fupport of the vital principle. 101.] Of thefe general caufes, thofe which operate more particularly in fevers feem to be, first, The violence oj re- action ; which either by repeated violent excitements, de- ftroy s the vital power itfelf; or, by its violence, .deftroy s the organization of the brain neceffary to the aaion of that power; or, by the fame violence, d^ftroys the organiza- tion of the parts more immediately ncceiiary to the circu- lation of the blood. Secondly, The caufe of death in fevers may be a poison, that i-'? a power capable of deftroying the vital principle^ t PRACTICE and thispoifonmaybe either the miafma or contagion which was the remote caufe of the fever, or it may be a putrid matter generated in the courfe of the fever. In both cafes, the operation of fuch a power appears either as aaing chiefly on the nervous fyftem, inducing the fymptoms of debility; or as aaing upon the fluids of the body, indu- cing a putrefcent ftate in them. 102.] From all this it appears, that the fymptoms fhow- ing the tendency to death in fevers, may be difcovercd by their being either the fymptoms Of violent reaction ; Of great debility ; Or, of a strong tendency to putrefaction in the flu,ids. Andupon this fuppofition, I proceed now to mark thofe fymptoms more particularly.* 103.] The fymptoms which denote the violence of reac- tion, are 1. The increafed force, hardnefs and frequency, of the pulfe. 2. The increafed heat of the body. 3. The fymptoms which are the marks of a general inflammatory diathefis, and more efpecially of a particular determination to the brain, lungs, or other important vifccra. 4. The fymptoms which are the marks of the caufe of violent re- aaion; that is of a ftrpng ftimulus applied, or of a ftrong fpafm formed, the latter appearing in a confiderable fup- preffion of the excretions. 104. The fymptoms which denote a great degree of de- iility, are, In the Animal Functions : I. The weaknefs of the * voluntary motions; II. The irregularity of the voluntary motions, depending on their debility; III. The weaknefs of fenfation; IV. The weaknefs and irregularity of the intelleaual operations. In the Vital Functions: I. The weaknefs of the pulfe ; II. The coldnefs and fhrinking of the extremities ; III. The tendency to a deliquium animi in an ered pof- ture; IV. The weaknefs of refpiration. * No part of medical knowledge is so serviceable in the practice of physic as prognostics. It wonderfully assists in the cure of all diseases, but more especially fevers, and other acute disorders. The young reader, therefore, ought to be particularly attentive to this part of the work. What the author advances is very different from what has gone before. We have here no hy- pothesis or fancies, no suppositions unsupported by facts ; but on the contra- ry, truths deduced from a careful cbitrvation of natui^, '.'v.fj ..>,) ,^ed in a distinct and perspicuous manner. OF PHYSIC. 61 In the Natural Functions: I. The weaknefs of the ftomach, as appearing in anorexia, naufea, and vomit- ing ; II. Involuntary excretions, depending upon a palfy of the fphinaers ; III. Difficult deglutition, depending up^. on a palfy of the mufcles of the fauces. 105.] Lastly, The fymptoms denoting the putrescent state of the fluids, are, I. With refpea to the ftomach; the loathing of animal food, naufea and vomiting, great thirft, and a defireof acids. II. With refpea to the fluids; 1. The blood drawn out of the veins not coagulating as ufual; 2. Hemorrhagy from different parts, without marks of increafed impetus; 3. Ef- fufions under the fkin or cuticle, forming patechia?, ma- culae, and vibices; 4. Effufions of a yellow ferum under the cuticle. III. With refpea to the ftate of the excretions; fetid breath, frequent loofe and fetid ftools, high coloured tur- bid urine, fetid fweats, and the fetor and lived colour of bliftercd places. IV. The cadaverous fmell of the whole body. 106.] Thefe feveral fymptoms have very often, each of them fingly, a fhare in determining the prognoftic; but more efpecially by their concurrence aiid combination with one another; particularly thofe of debility with thofe of putrefcency.* 107.] On the fubjea of the prognoftic, -it is proper to obferve, that many phyficians have been of opinion there is fomething in the nature of fevers which generally deter- in ine them to be of a certain duration; and therefore that their terminations, whether falutary or fatal, happen at cer- tain periods of the difeafe, rather than at others. Thefe periods are called the Critical Days; carefully mark- ed by Hippocrates and other ancient phyficians, as well as by moderns of the greateft eminence in practice; whilft at the fame time many other moderns, of no inconfiderable authority, deny their taking place in the fevers of thefe northern regions which we inhabit. * It may not be amiss to explain this circumstance a little more fully. Cold- ness of the extremities may alone be sufficient to induce practitioners'to think, the issue of the disease fatal ; yet if this symptom be combined with a weak- ness and irregularity of the intellectual operations, and these two accompani- ed with involuntary, loose, and foetid evacuations o;' stool, aiid •.;nr.e, rE/.ia rauy be pronounced to be at no great distance. 02 PRACTICE 10S.] I am of opinion that the doarine of the ancients,- and particularly that of Hippocrates, on the fubjea, wa^ well founded; and that it is applicable to the fevers of our climate. 109.] I am of this opinion, first, Becaufe I obferve that the animal economy, both from its own conftitution, and from habits which arc eafily produced in it, is readily fubjeaed to periodical movements. Secondly, Becaufe, in the difeafes or the human bpdy, I obferve periodical movements Lo take place with great conftancy and exaa. nefs; as in the cafe of intermittent fevers, and many other difeafes. 110.] Thefe confiderations render it probable, that ex- ^ aa periodical movements may take place in continued fe- vers ; and I think there is evidence of fuch movements ac- 1 tually taking piace. 111.] The critical days, or thofe on which we fuppofe the termination of continued fevers efpecially to happen, are, the third, fifth, seventh, ninth, eleventh, fourteenth, seventeenth, and twentieth. We mark none bevond this laft; becaufe, though fevers are fometimes protraded be- " yond this period, it is, however, more rarely; fo .that there- are not a fufficient number of obfervations to afcertain the courfe of them; and further, becaufe it is probable that*, in fevers long protra£ted, the movements become lefs exact and regular, and therefore lefs eafily obferved. 112.] That the days now mentioned are the critical days, feems to be proved by the particular fafts which are found in the writings of Hippocrates. From thefe faas, as col- leaed from the feveral writings of that author by M. do Haen, it appears, that of one hundred and fixty three in- fiances of the termination of fevers, which happened on- one or other of the firft twenty days of the difeafe,. there arc one hundred and feven, or more than two thirds of the whole number, which happened on one or other of the eight days above mentioned; that none happened on the fecond or thirteenth day; and upon the eighth, tenth, twelfth, fifteenth, fixteenth, eighteenth, and nineteenth, there are but eighteen inftanccs of termination, or one ninth of the whole. l_ 113.] As the terminations which happen on the feven OF PHYS I C. 63 "days laft mentioned, are, upon the whole, few; and, upon ^tny one of them, fewer than thofe which happen on any of oUr fuppofed critical days; fo there are therefore nine days which may be called x ox critical; while, on the other h?A\c], the many terminations which happened on the feventh, fourteenth, and twentieth days, afford a proof both of critical days in general, and that thefe are the chief of them. Hereafter I fhall mention an analogy that ren- ders the power of the other critical days fufticiently pro- bable. 114.] It appears further, that as, of the terminations which were final and falutary, not a tenth part happened on the noncritical days; and of the terminations which were final and fatal, though the greater number happened on the critical days, yet above a third of them happened on. the noncritical; fo it would appear that tfje tendency of the animal economy is to obferve the critical days, and that it is by the operation of fome violent and irregular caufe that the courfe of things is fometimes turned to the noncritical. 115.] What has been faid gives fufficient ground for prefuming, that it is the general tendency of the animal economy to determine the periodical movements in fevers to be chiefly on the critical days. At the fame time, we muft acknowledge it to be a general tendency only; and that, in particular cafes, many circumftances may occur to difturb the regular courfe of it. Thus, though the chief and more remarkable exacerbations in continued fevers happen on the critical days, there are truly exacerbations happening every day; and thefe, from certain caufes, may become confiderable and critical. Further, though inter- mittent fevers are certainly very ftrongly determined to obferve a tertian or quartan period, we know there are cer- tain circumftances which prevent them from obferving thefe periods exactly, and which render them either antici- pating or poftponing fo much, that the days of paroxyfms come to be quite changed ; and it is allowable to fuppofe, that the like may happen with refpect to the exacerbations of continued fevers, fo as thereby to difturb the regular appearance of critical days. A particular inftancc of this occurs with refpea to the fixfh day of fevers. In the writings of Hippocrates, there $4 PRACTICE are many inftances of terminations happening on the fixth day; but it is not therefore reckoned among the critical days; for, of the terminations happening on that day^ there is not one which proves finally of a falutary kind; the greater number are fatal; and all the reft are imperfea, and followed with a relapfe. All this fhows, that fome violent caufe had, in thefe cafes, produced a deviation from the ordinary courfe of nature; that the terminations on the fixth day are nothing more than anticipations of the feventh, and therefore a proof of the power of this laft.* 116.] The doctiine of critical days has been much em. barrafled by fome diffonant accounts of it, which appear in the writings imputed to Hippocrates.t But this may be juftlv accounted for frem thefe writings being truly the worts of different perfons, and from the moft genuine of them having fuffered many corruptions; fo that, in fhort, every thing which is inconfifteiit with the faas above laid down, may be afcribed to one or other of thefe caufes. 117.] This, further, has efpecially difturbed the doc- trine of critical days, that Hippocrates himfeif attempted, perhaps too haltily, to eftabhfh general rules, and to bring the doarine to a general theory, drawn from Pythagorean opinions concerning the power of numbers. It is this which feems to have produced the idea of odd days, and of a quaternary and feptenary period, do&rines which ap- * This idea of the general tendency of nature to preserve a regularity in the animal motions, is a most ingenious explanation of the apparent irregu- larities in the termination of fevers. It is perhaps one of the best defences cf the critical days that ever appeared, because it explains in a most satisfac- tory manner, why the termination on the sixth day should not be salutary. The Violence of the disturbing cause excites motions which nature has not the power of withstanding, and which are either the immediate causes of death, or induce such morbid affections as prove ultimately fatal. f To enter into a critical inquiry, whether the works handed down to us as the writings of Hippocrates are really the productions of that great man, or compilations from various physicians, would be foreign to the design of this work. The style of them is, if I may be allowed the expression, homogene* ous ; the same provincial dialect prevails through the whole of them ; and they ~re extremely remarkable, especially such of them as respect the critical da\s, for being rather a detail of observed facts, than reasonings brought to support a favorite hypothesis. It is probable indeed that Hippocrates, -who has got the credit of the work, might have been indebted 10 many of his co- temporaries for some of the materials that compose them ; but the sameness of the style is a strong presumptive argument that they are the production of one person, or at least of their having been reduced to their present form by ene and the same hand. Dr. Cullen's other supposition, of their having suf- fered many, and, he mi^ht have added, r.uteria! corruptions seems highly probable. OF PHYSIC. CS pear fo often in the writings of Hippocrates. Thefe, however, are inconfiftent with the faas above laid down ; and indeed, as Afclepiades and Celfus have obferved, are inconfiftent with one another. 118.] Upon the whole, therefore, it is apprehended, that the critical days above affigned are truly the critical days of Hippocrates, and may be confiftently explained in the following manner. 119.] From the univerfality of tertian or quartan peri- ods in intermittent fevers, we cannot doubt of there being, in the animal economy, a tendency to obferve fuch peri- ods ;* and the critical days above mentioned are confift- ent with this tendency of the economy, as all of them mark either tertian or quartan periods. Thefe periods, however, are not promifcuoufly mixed, but occupy conftantly their feveral ffortions in the progrefs of the difeafe; fo that, from the beginning to the eleventh day, a tertian period takes place, and, from the eleventh to the twentieth, and perhaps longer, a quartan period is as fteadily obferved. 120.] What determines the periods to be changed about the eleventh day, we have not clearly perceived; but the faa is certain : for there is no inftance of any termination on the thirteenth, that is, the tertian period next following the eleventh ; whereas, upon the fourteenth, feventeenth, and twentieth, which mark quartan periods, there are forty- three inftances of terminations, and fix only on all the in- termediate days between thefe. This prevalence of a quartan period leaves no room for doubting that the twentieth, and not the twenty-firft, is the critical day marked by Hippocrates, though the laft is men- tioned as fuch in the common edition of the Aphorifms, taken from an erroneous manufcript, which Celfus alfo feems to have copied. 121.] A confiftency with the general tendency of the fyftem renders the feries of critical days we have mentioned probably the true one; and the only remaining difficulty in finding what we have delivered to be the fame with the genuine doarine of Hippocrates, is the frequent mentioA of the fourth as a critical day. * The Author jnight have added, or periods compounded of tbe&e two. Vol. I. I SS PRA-CTJCI! It is true there are more inftanccs of terminations Ivap- pening on this day, than on fome of thofe days we have af- fcrted to be truly critical: but its inconfiftcncy with the more general tendency, and fome other confiderations, lead us to deny its being naturally a critical day ; and to think that the inftances of terminations, which have really occur- red on the fourth day, are to be reckoned among the other . * irregularities that happen in this matter. 122.] I have thus endeavored to fupport the doarine of critical days, chiefly upon the particular faas to be found in the writings of Hippocrates : And although I might al- fo produce many other teftimonies of both ancient and mo- dern times; yet it muft be owned, that fome of thefe tef- ; timonies may be fufpeacd to have arifen rather from a ve- * neration of Hippocrates, than from accurate obfervation,. 123.] With refpea to the opinions of many»moderns who deny the prevalence of critical days, they arc to be little regarded, for the obfervation of the courfe of conti- nued fevers is known to be difficult and fallacious ; and therefore the regularity of that courfe may have often efca- fed inattentive and prejudiced obfervers. 124.] Our own obfervations amount to this, That fe- vers with moderate fymptoms, generally the cafes of the fynocha, frequently terminate in nine days, or fooner, and very conftantly upon one or other of the critical days which fall within that period : but it is very rare, in this climate, that cafes of either the typhus or fynochus terminate be- fore the eleventh day ; and when they do terminate on this day, it is for the moft part fatally. When they are pro- tracted beyond this time, I have very conftantly founds that their terminations were upon the fourteenth, feven- teenth, or twentieth day. In fuch cafes, the falutary terminations arc fcldom at- tended with any confiderable evacuation. A fweating fre- quently appears, but is feldom confiderable ; and I have hardly ever obferved critical and decifive terminations at- tended with vomiting, evacuations by ftool, or remarkable changes in the urine. The folution of the difeafe is chief- ly to be difcerned from fome return of fleep and appetite, the ceafing of delirium, and an abatement of the frequency of the pulfe. By thefe fymptoms we can often mark'a crifis OF PHYSIC. 67 = "■ •» " of the difeafe : but it feldom happens fuddenly and entire. ly ; and it is moft commonly from ioine favorable fymp- toms occurring upon one critical"day,that we can announce a more entire folutionupon the next following.. Upon the whole, I am pcrf uaded, that if obfervations fhall be made with attention, and without prejudice, I fhall be allowed to conclude, with the words of the learned and fagacious Gaubius, "Fallor,ni Tua cenftitcrit Hippocra- ti audoiitas, Galeno fides, Nature virtus et ordo." ----- '■■■ .TM»ftC3Sj*g«««- " ---- CHAP.

Of the Cure of Continued Fevers.. 125.] XjlS it is allowed, that in every fever which has its full courfe, there is an effort of nature of a falutary tenden- cy, it might be (ippofedthat the cure of fevers fhould be left to the operations of nature, or that our art fhould be only direfcted to fnpport and regulate thefe operations, and that we fhould form the indications accordingly. This plan, however, I cannot adopt, becaufe the operations of nature are very precarious, and not fo well underftood as to ena- ble us to regulate them properly. It appears to me, that milling to thefe operations has often given occafion to a negligent and inert praaice; and there is reafon to believe, that an attention to the operations of nature may be often fupcrceded by art. 126.] The plan which to me appears to be moft fuitable is that which forms the indications of cure upon.the view of obviating the tendency to death ; while at the fame time the means of executing thefe indications are directed by a proper attention to the proximate caufe of fevers. Upon this plan, in confequence of what has been laid down above on the tubject of the prognoftic, we form three general indications in the cure-of continued fevers ; and the one or other of thefe is to be employed according as the circumftances of the fever (102.) fhall direct. The firft therefore is} To moderate the violence of reaction. 6* PRACTICE The fecond is, Toremovethe causes or obviate the effects ef debility. And, The third is, To obviate or correct the tendency of the fiuids to putrefaction. 127.] The firft indication may be anfwered, that is, the violence of reaaion may be moderated. 1. By all thofe means v^ich diminifh the aaion of the heart and arteries. * 2. By thofe means which take off the fpafm of the ex- treme veffels, which we fuppofe to be the chief caufe of violent reaaion. 128.] The aaion of the heart and arteries may be di- minifhed, 1. By avoiding or moderating thofe irritations, which in • *• one degree or other,are almoft conftantly applied to the body. 2. By the ufe of certain fedative powers. 3. By diminifhing the tenfion and tone of the arterial • fyftem. 129.] The irritations (128. 1.) almoft conftantly appli- ed, are the impreffions made upon our fenfes; the exercife of the body and mind ; and the taking in of aliments. The avoiding thefe as much as poffible, or the moderating their force, conftitute what is rightly called the Antiphlo- gistic Reg 1 men, proper to be employed in almoft every Continued fever. 130.] The condua of the regimen is to be direaed by the following rules and confiderations. 1. Impreffions on the external fenfes, as being ftimulant to die fyftem, and a chief fupport of its aaivity, fhould be avoided as much as poffible; thofe efpecially of more conftant application, thofe of a ftronger kind, and thofe which give pain and uneafinefs. No impreflion is to be more carefully guarded againft than that of external heat; while at the fame time, every other means of increafing the heat of the body is to be fhmi- ned. Both thefe precautions are to be obferved as foon as the hot ftage is fully formed, and to be attended to during its continuance ; excepting in certain cafes, where a deter- mination to fweating is neceffary, or where the ftimulant effeas of heat may be compenfated by circumftances which determine it to produce a relaxation and revuliion. OF PHYSIC. 69 2. All motion of the body is to be avoided, efpecially that whfch requires the exercife of its own mufcles; and that pofture of the body is to be chofen which employs the feweft mufcles, and which keeps none of them long in a ftate of contraaion. Speaking, as it accelerates refpira- tion, is particularly to be refrained from. 3. The exercife of the mind .alfo is a ftimulus to the bo- dy ; fo that all impreffions, fchich lead to thought, and thofe efpecially which may excite emotion or paffion, are to be carefully fhunned. With refpea to avoiding impreffions of all kinds, an ex- ception is to be made in the cafe of a delirium coming on, when the prefenting of accultomed objeas may have the effea of interrupting and diverting the irregular train of ideas then arifing in the mind. 4. The prefence of recent aliment in the ftomach proves always a ftimulus to the fyftem, and ought therefore to be as moderate as poffible. A total abftinence for fome time may be of fervice; but as this cannot be long continued with fafety, we muft avoid the ftimulus of aliment, by choofing that kind which gives the leaft.* We fuppofe that alimentary matters are more ftimulant, according as they are more alkalefcent; and this leads to avoid all animal, and to ufe vegetable food only. As our drinks alfo may prove ftimulant, fo all aromatic and fpirituous liquors are to be avoided; and in anfwering the prefent indication, all fermented liquors, excepting thofe of the loweft quality, are to be abftained from.t 131.] Befides thefe ftimulant powers more conftantly applied, there are others which, although occafionally on- ly, yet, as commonly [accompanying fevers, muft be at- tended to and removed. J * In addition to these directions, it may be mentioned, that if the patient have a desire for food, which is seldom the case, he ought to make very spa- ring and frequent meals. Much food taken at once, proves a greater stimulus than the same quantity taken at several different times ; especially if suffici- ent quantities of diluting mucilaginous drink, such as lihtseed tea, barley- water, water-gruel, Sic. be taken along with it. f Thin liquors are the best in cases of this kind : of these we may either use water alone, or weak lintseed tea, thin barley-water, toast and water, whey, currant-jelly dissolved in water, with a variety of such mucilaginous acesceppdrinks. They ought to be taken in small quantities, and often. | Tms passage might have been more clearly expressed thus: besides the stimulant power* more constantly applied, others, only occasionally accompa- nying fevers, must be attended to and removed.- 70 PRACTICE One is, the fenfe of thirft, which, as a powerful ftimuTlis, ought always, in one way or other, to be removed.'* Another ftimulus frequently arifes from crudities, or corrupted humors in the ftomach ; and it is to be removed by vomiting, by dilution, or by the ufe of acid.f A third ftimulus often arifes from the preternatural re- tention of faeces in the interlines ; and ought to be remo- ved by frequent laxative grafters.J A fourth ftimulus to be conftantly fufpeacd in fevers, is a general acrimony of the fluids, as produced by the in- creafe of motion and heat, joined with an interruption of the excretions. This acrimony is to be obviated or remo- ved by the taking in of large quantities of mild antifeptic liquors.|| 132.] The avoiding of irritation in all thefe particulars, (130. and 131.) conftitutes the antiphlogiftic regimen ab- solutely neceffary for moderating the violence of reaction ; and, if I miftake not, is proper in almoft every circum- ftance of continued fevers ; becaufe the propriety and fafe- ty of employing ftimulants is often uncertain ; and becaufe feveral of thofe above mentioned, befide their ftimulant powers, have other qualities by which they may he hurtfuh It appears to me, that the fuppofed utility of ftimulants, in certain cafes of fever, has often arifen from a miftake in having afcribed to their ftimulant, what really depended upon their antifpafmodic power. 133.] A fecond head of the means (128. 2.) for mode* rating the violence of reaaion, comprehends certain feda- * The drinks mentioned in the former note are best adapted to this purpose. f The vegetable acids are the most suitable, especially the juices of acid fruits, as the juices of oranges, lemons, currants or apples, diluted with wa- ter. In some cases the mineral acids have been much extolled, especially the nitrous, when united with the spirit of wine. The spiritus stheris nitrosi of the last London Pharmacopoeia is used with success in these cases. It may- be given in barley-water, to the quantiry of twenty ot twenty-five drops with'. in the hour. + The preference of glysters to purging medicines is obvious.—The action even of the most gentle laxatives is always attended with some degree of sti- mulus, while glysters, especially the mild ones, seldom produce that effect. The best glyster in these cases, is half a pint of milk, with as much water, two ounces of oil, and one ounce of brown sugar, or, what is better than sv' gar, two ounces of manna. || The chief of these are the acid fruits diluted with water : to which, we may add the decoction of malt, of radix graminis, (the Triticum repens of Linne.) infusions of sage, mint, and other plant* ef that natural order which X-inne calls Spirantia. or PHYSIC. 71 ?ive powers, which may he employed to diminifh the aai- vity of the whole body, and particularly that of the fan- guiferous fyftem. The first of thefe to be mentioned is the application of cold. Heat is the chief fupport of the activity of the animal fyftem ; which is therefore provided in itfelf with a power of generating heat. But, at the fame time we obferve, that this would go to excefs, were it not conftantly moderated by a cooler temperature in the furrounding atmofphere. When, therefore, that power of the fyftem generating heat is increafed, as is commonly the cafe in fevers, it is necef- fary not only to avoid all means of increafing it further, hut it feems proper alfo to apply air of a cooler tempeia- ture ; or at leaft to apply it more entirely and freely, than in a ftate of health. Some late experiments in the fmall pox and in continu- ed fevers, fhow that the free admiffion of cool air to the body is a powerful remedy in moderating the violence of reaaion ; but what is the mode of its operation, to what circumftances of fever it is peculiarly adapted, or what li- mitations it requires, I fhall not venture to determine, till more particularly inftrutled by further experience. 134.] A second fedative power which may be employed in fevers, is that of certain medicines, known, in the writ- ings on the Materia Medica, under the title of Refrige- rants. The chief of thefe are acids of all kinds, when fuffici- ently diluted ; and they are, in fevcral refpeas, remedies adapted to continued fevers. Thofe efpecially in ufe are, the Vitriolic and Vegetable; and, on many accounts, we prefer the latter.* 135 ] Another fet of refrigerants are, the Neutral Salts, formed of the vitriolic, nitrous or vegetable acids; with al- kalines, eiftier fixed or volatile. All thefe neutrals, while * The vitridic acid is harsh to the taste, and frequently acts as an astrin- gent; it is therefore not always admissible. The best vegetable acids for this purpose, are as was said above, the natural juices of acid fruits. The acid of tartar is the best refrigerant we have: there is an excellent formula of it in the Swedish Pharmacopoeia, under the title of Pulvis refrigerans, which consists chiefly of the essential salt ; r" tartar and sugar. The dose ct the acid of tartar, prepared according to Scheele's prescription, is half a scru- ple, cr fifteen grains, in th* hour, largely diluted with a mucilaginous liquor. 72 PRACTICE they are'fflflblving in water, generate cold; but as that cold ceafes foon after the folution is fiuifhcd, and as the falts are generally exhibited in a diflolved ftate, their refri- gerant power in the animal body docs not at all depend up- on their power of generating cold with water. The neu- tral chiefly employed as a refrigerant, is Nitre; but all the others, "compounded as above mentioned, partake more or lefs of the fame quality.* 136.] Befides thefe neutrals, fome metallic falts alfo have been employed as refrigerants in fevers; and particu- larly the Sugar of Lead. But the refrigerant, powers of this are not well afcertained; and its deleterious qualities are too well known to admit of its being freely ufed. 137.] Under the third general head (128. 3.) of the means to be employed for moderating the violence of re- action, are comprehended the fevcral means of diminifh- ing the tenfion, tone, and activity, of the fanguiferous fyf- tem. As the aaivity of this fyftem depends, in a great meafure, upon the tone, and this again upon the tenfion of the veffels, given to them by the quantity of fluids they contain, it is evident, that the diminution of the quantity of thefe muft diminifh the aaivity of the fanguiferous fyftem. 138.] The quantity of fluids contained in the fanguifer- ous fyftem, may be diminifhed moft conveniently by the evacuations of blood-letting and purging. 139.] Nothing is more evident, than that blood-letting is one of the moft powerful means of diminifhing the acti- vity of the whole body, efpecially of the fanguiferous fyf- tem ; and it muft therefore be the moft effectual means of moderating the violence of reaaion in fevers. Taking this as a fact, I omit inquiring into its mode of operation, and fhall only confider in what circumftances of fevers it may be moft properly employed. 140.] When the violence of reaaion, and its conftant attendant, a phlogiftic diathefis, are fufticiently manifeft ; when thefe conftitute the principal part of the difeafe, and may be expeaed to continue throughout the whole of it, * Nitre has been leng used as a refrigerant. In too large quantities, how- ever, it has often done harm. It may therefore be necessary to guard the young practitioner against giving nitre in a larger quantity than two drachms in the twenty-four hours, nor in do,-,£■; of above ten grains, well diluted with* mucilaginous drinki. OfPHYSIC. *S as in the cafes-of synocha ; then blood-letting is the princi- pal remedy, and may be employed as far as the fymptoms of the difeafe may feem to require, and the conftitution of the patient will bear. It is, however, to be attended to, ^ that a greater evacuation than is neceffary, may occafion a flower recovery, may render the perfon more liable to are- lapfe, or may bring on other difeafes. 141.] In the cafe of synocha, therefore, thefe is little doubt about the propriety of blood-letting: but there are other fpecies of fever, as the synochus, in which a violent rea6tion and phlogiftic diathefis appear, and prevail during fome part of the courfe of the difeafe ; while, at the fame time, thefe circumftances do not conftitute the principal part of the difeafe, nor are to be expeaed to continue du- ring the whole courfe of it, and it is well known, that in many cafes, the ftate of violent reaaion is to be fucceeded, fooner or later, by a ftate of debility from the excefs of which the danger of the difeafe is chiefly to arife. It is$ therefore, neceffary, that, in many cafes, blood-letting fhould be avoided, and even although, during the inflam- matory ftate of the difeafe, it may be proper, it will be ne- ceffary to take care that the evacuation be not fo large as to increafe the ftate of debility which is to follow. 142.] From all this it muft appear, that the employing blood-letting, in certain fevers, requires much difcernment and fkill, and is to be governed by the confideration of the following circumftances; 1. The nature of the prevailing epedemic. 2. The nature of the remote caufe. 3. The feafon and climate in which the difeafe occurs, 4. The degree of phlogiftic diathefis prefent.* 5. The period of the difeafe. 6. The age, vigour, and plethoric ftate of the patient. 7. The patient's former difeafes and habits of blood- letting, -j'-' 8. The appearance of the blood drawn out. 9. The effeas of the blood-letting that may have been already praaifed. 143.] When, after the confideration of thefe circum- ftances, blood-letting is determined to be neceffary, it * The phlogistic diathesis is explained in art. 247. Vol. I. K 74 PRACTICE mould be obferved, that it is more cffeaual, according as the blood is more fuddenly drawn off, and as the body is at the fame time more free from all irritation, and confe- quently when in a pofture in which the feweft mufcles arc in aaion. 144.] Another evacuation whereby the quantity of fluids contained in the body can be confidcrably diminifhed, is that of Pitrging. 145.] If we confider the quantity of fluids conftantly pre- fent in the cavity of the inteftines, and the quantity which may be drawn from the innumerable excretories that open into this cavity, it will be obvious, that a very great evacu- ation can be made by purging; and, if this be done by a ftimulus applied to the inteftines, without being at the fame time communicated to the reft of the body, it may, by emp- tying both the cavity of the inteftines, and the arteries which furnifh the excretions poured into it, induce a confiderable relaxation in the whole fyftem; and therefore, purging feems to be a remedy fuited to moderate the violence of reaaion in fevers. 146.] But it is to be obferved, that as the fluid drawn from the excretories opening into the inteftines, is not all drawn immediately from the arteries, as a part of it is drawn from the mucous follicles only; and as what is even more immediately drawn from the arteries, is drawn off flowly, fo the evacuation will not, in proportion to its quantity, occafion fuch a fudden depletion of the red vef- fels, as blood-letting does; and therefore cannot operate fo powerfully in taking off the phlogiftic diathefis of the fyftem. 147.] At the fame time, as this evacuation may induce a confiderable degree of debility; fo, in thofe cafes, in which a dangerous ftate of debility is likely to occur, purg- ing is to be employed with a great deal of caution; and more efpecially as the due meafure of the evacuation is more difficult to be applied dian in the cafe of blood- letting. 148.] As we fhall prefently have occafion to obferve, that it is of great importance, in the cure of fevers, to re- ftore the determination of the blood to the veflels on the iurfaceof the body; fo purging, as in fome meafure tak- OF PHYSIC. 75 mg off that determination, feems to be an evacuation not well adapted to the cure of fevers. 149.] If, notwithstanding thefe doubts, (146. 147. and 148.) it fhall be afferted, that purging, even from the exhi- bition of purgatives, has often been ufeful in fcv'ers; I would beg leave to maintain, that this has not happened from a large evacuation; and therefore, not by moderat- ing the violence of reaaion, excepting in the caf*of a more purely inflammatory fever, or of exanthemata of an inflam- matory nature. In other cafes'of fever, I have feen a large evacuation.by purging, of mifchievous confequence ; and if upon occafion, a more moderate evacuation has appear- ed to be ufeful, it is apprehended to have been only "by taking off the irritation of retained-fa*ces, or by evacuat- ing corrupted humours, which happened to be prefent in the inteftines ; for both of which purpofes, frequent laxa- tives may be properly employed.* 150.] Another fet of means (127.2.) for moderating the violence of reaaion in fevers, are thofe fuited to take off the fpafm of the extreme veffels, which we believe to be the irritation that chiefly fupports the reaaion. Though I have put here thi* indication of taking off the fpafm of the extreme veffels, as iuborcinate to the general' indication of moderating the violence of rea£tion; it is, however, to be obferved here, that as fever univerially confifts in an increafed action of the heart, either in fre- quency or in force, which in cither cafe is fupported by a fpafm of the extreme veffels, fo the indication for remov- ing this is a very general one,, and applicable in almoft eve- ry circumftance of fever, *f-itiia,n ©unce or ten div*hr..s i.i br.v,Ie;'-\Y3.:er or fcisth. 70 FR AC 1 i u -L. i5i.] For taking off the fpafm of the extreme vcfliTs,, the means to be employed arc either internal or external. 152.] The internal means (151.) are, 1. Thofe which determine the force of the circulation to the extreme veffels on the furface of the body, and, by rcftoring the tone and aaivity of thefe veffels, may over- come the fpafm on their extremities. 2. Tho/e medicines which have the power of taking off fpafm in any part of the fyftem, and which arc known un- der the title of Antispasmodics. 153.] Thofe remedies which are fit to determine to the furface of the body, are, 1. Diluents. 2. Neutral Salts,. 3. sudorifics. 4. Emetics. 154.] Water enters, in a large proportion, into the coir. pofition of all the animal fluids, and a large quantity of it is always diffufed through the whole of the common mafs. Indeed, in a found ftate, the fluidity of the whole mafs de- pends upon the quantity of water prefent in it. Water, therefore, is the proper diluent of our mafs of blood; and other fluids are diluent only in proportion to the quantity of water they contain. 155.} Water may be faid to be the vehicle of the feve- ral matters which ought to be excerned; and in a healthy ftate the fulnefs of the extreme veffels, and the quantity of excretions, are nearly in proportion to the quantity of wa- ter prefent in the body. In fever, however, although the excretions are in fome meafure interrupted, they continue in fuch quantity as to exhale the more fluid parts of the blood ; and while a portion of them is at the fame time ne- ceiTarily retained in the larger veffels, the fmallcr and the extreme veffels, both from the deficiency of fluid, and, their own contraaed ftate, are lefs filled, and therefore al- lowed to remain in that condition. 15.6/] To remedy this contraaed ftate, nothing is more ncceffary than a large fupply of water or watery fluids, ta- ken in by drinking or otherwife; for as any fupcrfluous quantity of water is forced off by the feveral excretories, fuch a force applied, may be a means of dilating the ex^ OF P H Y SIC. 7/ treme veffels, and of overcoming the fpafm affeaing their extremities. 157.] Accordingly the throwing in of a large quantity of watery fluids has been, at all times, a remedy.much cm- ployed in fevers; and in no inftance more remarkably, than by the Spanifli and Italian phyficians, in the ufe of what they call the Dioeta aquca. 158.] This practice confifts in taking away every other kind of aliment and drink, and in giving in divided portions every day, for feveral days together, fix or eight pounds of plain water, generally cold, but fometimes warm. AH this, however, is to be done only after the difeafe has continued for fome time, and, at leaft, for a week.* 159.] A fecond means (153 2.) of determining to the furface of the body, is by the ufe of neutral falts. Thefe, in a certain dofe taken into the itomach, produce, foon af- ter, a fenfe of heat upon the fuiface of the body; and, if the body be covered clofe and kept warm, a fweat is rea- dily brought out. The fame medicines, taken during the cold ftage of a fever, very often put an end to the cold ftage, and firing on the hot; and they are alfo remarkable for flopping the vomiting- which fo frequently attends the cold ftage of fevers. All this fhows, that neutral falts have a power of determining the blood to the furface of the bo- dy, and may therefore be of ufe in taking off the fpafm which in fevers fublifts there. 160.] The neutral moft commonly employed in fevers, is that formed of an alkali with the native acid of vegeta- o * Simply as a diluent, water is undoubtedly the best drink that can be used, but by adding a small quantity of mucilage to it, two intentions are answered at the same time, viz. diluting and overcoming the acrimony ; hence the pro- priety of barley-water, water-gruel, lintseed tea, all made extremely weak ; of very slight decoctions of malt, of bread-crusts, or even the gelatinous parts of young animals, as calf's feet, or the more solid hartshorn shavings, &.c. These animal substances must however, be used in great moderation, and on- ly in those cases where the patient requires nourishment. When this watery regimen is carried to a great length, the patient turns anasarcous ; but this effect may be prevented by some of the neutral salts, of which the Kali ace- tatum of the London Pharmacopoeia is mo»i preferable, on account of its diu^ retic quality. The dose of it may be carried as far as half an ounte or six drachms in the day. The same intention may also be answered by eating water-cresses, radishes,if in season, or a little of theouterrind oi" turnips ;.all ©f which arc diuretics. "73. PRACTICE bles,* but all the other neutrals have more or lefs of the fame virtue ; and perhaps fome of them, particularly the ammoniacal falts, poflefs it in a ftronger degree.t 161.] As cold water taken into the ftomach, often fhows the fame diaphoretic effeas with the neutral falts, it is pro- bable that the effea of the latter depends upon their refri- gerant powers mentioned above, (134.) What is'the ef- fea of the neutral falts, given when they are forming and in a ftate of effervefcence ? It is probable that this circum- ftance may increafe the refrigerant power of thefe falts, and may introduce into the body a quantity of fixed-air; but for thefe purpofes it would feem proper to contrive that the whole of the effervefcence fhould take place in the ftomach/J" 162.] A third means (153. 3.) of determining to the fur- face of the body, and taking off the fpafm fubfi fling there, is by the ufe of fudorific medicines, and of fweating. 163.2 The propriety of this remedy has been much dis- puted ; and fpecious arguments may be adduced both for and againft this praaice. In favor of the praaice it may be hid,* 1. That, in healthy perfons, in every cafe of increafed aaion of the heart and arteries, a fweating takes place, and is feemingly the means of preventing the bad effects of fuch increafed action. 2. That, in fevers, their moft ufual folution and termi- nation is by fpontaneous fweating. 3. That, even when excited by art, it has been found manifeftly ufeful, at certain periods, and in certain fpecies- of fever. • The following is the usual dose of it every three or four hours : R. Sal. Absinth. 9i. Succ Limon. §v,. vel. p. s. ad. saturationcm ; Addc Aq. i-'ontanx glss. Syrup, comrnun. 3ii. M. f. haust. t The form and dose of this is the same with the foregoing, onlv using tha volatile alkali instead of the fixed. The aqua ammonia acetata of the London- Pharmacopoeia is one of the ammonixal salts, and may be given in doses oi" two drachms every four hours, diluted with an ounce and a half of water. $ It is certainly extreWly useful in suppressing vomitings in fevers. The method of producing the effervescence in* the stomach i= as follows:- Let the patient take the acid first, diluted with a sufficient quantity of water, and im- mediately after let him swallow the alkali, also diluted. The proportion of the alkali to the acid must be learned from chemistry. If the mild fixed alkaU' is good, it will saturate abou: twelve Ur.i^ its. weight ci' lemon juice. OF PHYSIC. 73 164.] Upon the other hand, it may be urged againft the jpraaice of fweating, 1. That as in fevers a fpontaneous fweating does not im- mediately come on, fo there muft be in thefe fome circum- ftances different from thofe in a ftate of health, and which mav therefore render it doubtful whether the fweating can be fafely excited by art. 2. That, in many cafes, the praaice has been attended with bad confcquences. The means commonly employed have a tendency to produce an inflammatory diathefis; which, if not taken off by the fweat following their ufe, muft be increafed with much danger. Thus, fweating em- ployed to prevent the acceffions of intermitting fevers, has often changed them into a continued form, which is always •dangerous. 3. The utility of the praaice is further doubtful, be- caufe fweating, when it happens, does not always give a fi- nal determination; as muft be manifcft in the cafe of inter- mittents, as well as in many continued fevers, which are fometimes in the beginning attended with fweatings that do not prove final;"and, on the contrary, whether fpontaneous or excited by art, feem often to aggravate the difeafe. 165.J From thefe confiderations, it is extremely doubt- ful ifrhe praaice of fweating can be admitted very generally; but at the fame time, it is alfo doubtful, if the failure of the praaice, or the mifchiefs faid to have arifen from it, have not been owing to the improper condua of the prac- titioner. With refpe£t to this laft, it is almoft agreed a- mong phyficians. 1. That fweating has been generally hurtful, when ex- cited by_ ftimulant, heating, and inflammatory medicines. 2. That it has been hurtful, when excited by much ex- ternal heat, and continued with a great increafe of the heat of the body. 3. That it is always hurtful, when it does not foon re- lieve, but rather increafes, the frequency and hardnefs of the pulfe, the anxiety and difficulty of breathing, the head- ach, and delirium. 4. That it is always hurtful, if it be urged when the fweat is not fluid, and when it is partial, and on the fupe- rior parts of the body only. SO PRACTICE 166.] In thefe cafes, it is probable, that either an in- flammatory diathefis is produced, which increafes the fpafm on the extreme veffels; or that, from other caufes, the fpafm is too much fixed to yield eafily to the increafed ac- tion of the heart and arteries ; and, upon either fuppofiti- on, it muft be obvious, that urging the fweat, as ready to produce a hurtful determination to fome of the internal parts, may be attended with very great danger. 167.] Though the doubts flarted (164.) are to be atten- ded to; and although the praftices (165.) having been found hurtful, are therefore to be rejected; it ftill renfains true. 1. That fweating has certainly been often ufeful in pre- venting the acceffion of fevers, when the times of this have been certainly forefeen, and a proper condua employed. 2. That, even after fevers have in fome meafure come on, fweating, when properly employed, either at the very beginning of the difeafe, or during its approach and gra- dual formation, has often prevented their further progrefs. 3. That, even after pyrexia? have continued for fome time, fweating has been fuccefsfully employed in curing them, as particularly in the cafe of rheumatifm. 4. That certain fevers, produced by a very powerful fedative contagion, have been generally treated, lb far as we vet know, moft fuccefsfully by fweating. 168.] Thefe inftances (167,) are in favour of fweating, but give no general rule; and it muft be left to further ex- perience to determine how far any general rule can be ef- tablifhed in this matter. In the mean time, if the praaice of fweating is to be attempted, we can venture to lay down •the following rules for the condua of it. 1. That it fhould be excited without the ufe of ftimu- lant inflammatory medicines. 2. That it fhould be excited with as little external heat,- and with as little increafe of the heat of the body, as poffi- ble. 3. That when excited, it fhould be continued for a due length of time, not lefs than twelve hours, and fometimes for twenty-four or forty-eight hours; always however, pro- viding that it proceeds without the circumftances menti- oned (165. 3. 4.) OF PHYSIC. 81 4. That for fome part of the time, and as long as the perfon can eafily bear, it fhould be carried on without ad- mitting of fleep.* 5. That it fhould be rendered univerfal over the whole body;and, therefore, particularly, that care betaken to bring the fweating to the lower extremities. 6. That the practice fhould be rendered faferbymoderate purging, excited at the fame time. 7. That it fhould not be fuddenly checked by cold any how applied to the body. 169.J When attention is to be given to thefe rules, the fweating may be excited, 1. By warm bathing, or a fomen- tation of the lower extremities. 2- By frequent draughts of tepid liquors chiefly water, rendered more grateful by the addition of a light aromatic,t or more powerful by that of a fmall quantity of wine. 3. By giving fome doles of neutral falts.* 4. Moft efFe&ually, and perhaps moft fafe- ly, by a large dofe of opiate, joined with a portion of neu- tral falts, and of an emetic.|j * This direction is not always absolutely necessary. f The light aromatics here mentioned are sage, mint, balm, &c. For the purpose of sweating, white wines answer best, especially the thin fresh wines ; as also Rhenish wines, particularly Hock. They must be taken warm and plentifully diluted. Wine whey is also a very powerful sudorific, as are also wheys made with vinegar, cream of tartar, the juices of acid fruits, or with dulcified spirit of nitre. \ Neutral salts may be given in the quantity of two scruples or a drachm : but the patient must nevertheless drink large quantities of warm water. The tartarous tartarisatus is the neutral most frequently used for producing sweats; its dose is generally £)i. but it may be increased to two drachms. || This is the well known Dover's powder, now called in the London Phar- macopoeia, pulvis ipecacuanhse compositus. It consists of 8 parts of neutral salt, one of opium, and one of ipecacuanha ; so that 10 grains of it are an ordinary dose : But it has been given to the quantity of a scruple wfthout a- ny bad consequences, and that dose repeated every two or three hours, till the effect was produced. In general, however, doses of 12 or 15 grains are the most usual, and are found by experience to be the best. The Dover's powder, when given in large quantities, often nauseates, and is rejected by vomit. In the Edinburgh Pharmacopoeia, the Dover's powder consists of 9 parts of neutral salt, one of opium, and one of ipecacuanha. The dose of this, therefore, will be nearly the same as the dose of the former ; 11 grains of Edinburgh Dover's powder being equivalent to 10 of the London. In ad- ministering this powder it may be necessary to observe, that the patient $ ought to refrain from drinking for at least an hour after taking it, because it nauseates more readily if much diluted }n the stomach ; and if the nausea be so great as to produce vomiting, its effects as a sudorific are considerably di- minished : when, however, a sweat is produced, thin diluting drinks may and ought to be plentifully given ; for in such cases, it is evident from the effect, that the medicine has passed out of the storna«h, and that no material ' nausea can then be produced by it. V»L.I. L 82 Practice In what cafes may cold water, thrown into the ftomach in large quantities, be employed to excite fweating ? See Celsus, Lib. III. chap, vii—ix. 170.] The fourth means (153. 1.) of determining to the fuiface of the body, and thereby taking off the fpafm affect- ing the extreme veffels, is by the ufe of emetics. °i7i-.] Emetics, and particularly antimonial emetics, have been employed in the cure of fevers ever fince the intro- du6lion of chemical medicines-: but for a long time, they were employed by chemifts and chemical praaitioners on- ly ; and although of late the ufe of them has become very general, their eificacy is ftill difputed, and their manner of operating is not commonly explained* 172.] Vomiting is, in many refpeas, ufeful in fevers; as it evacuates the contents of the ftomach; as it emulges the biiiary and pancreatic duas; as it evacuates the con- tents of the duodenum, and perhaps, of alfo a larger porti- on of the inteftines; as it agitates the whole of the abdo- minal vifcera, expedes the circulation in them, and pro- motes their feveral fecretions ; and laftly, as agitating alfo the vifcera of the thorax, it has like effeas there. AH thefe feveral effeas are in many cafes and circumftances of fever, procured with advantage; but do not properly fall under our view here, where we are to confider only the ef- fea of vomiting in determining to the furface of the body. 173.] This effea we do not impute to the exercife of vomiting in agitating the whole frame; but to the particu- lar operation of emetics upon the mufcular fibres of the fto- mach, whereby they excite the action of the extreme arte- ries on,the furface of the body, fo as thereby effeaually to determine the blood into thefe veffels, remove the atony, and take of the fpafm affeaing them. 174.] That fuch is the power of emetics, will appear from * AH the antimonial emetics are violent in their effects, and are sometimes attended with disagreeable consequences. Emetic tartar is found from ex- perience to be the safest of them ; but it is not always of the same strength, unless peculiar attention be paid to the making of it. The prescription for i* in the last Edinburgh'Pharmacopceia is preferable to that in the London. Some Chemists think that it would be better to use boiling water alone, and omit the alkaline salt, alledging that the alkali renders the precipitation variable in point of strength : But this opinion is erroneous. The alkali is used in or- der to free the precipitate more completely from any remains of the muriatic ■acid, making it thereby a milder powder and a more perfect calx.- OF PHYSIC. the fevcral confiderations mentioned above (44) and there- fore, that they are remedies well fuited to the cure of fevers. 175. J Emetics, for that purpofc, arc adminiftcfed in two different ways : that is, either in fuch doles as may excite full and repeated'vomitings;. or in fuch dofes as may ex- cite ficknefs and naufea only,.with little or no vomiting at all". 176.3 Full vomiting is belt fuited to the feveral purpo- . fes mentioned 172. and is alfo well fuited to determine to the furface of the body, fo as thereby to obviate the atony and fpafm which lay the foundation of fever. Thus vomit- ing, excited a little before die expeaed acceffion of the pa- roxyfm of an intermittent, has been found to prevent the paroxyfm altogether. And it has been obferved alfo, that when contagion Has been applied to a perfon, and firft dif- covers its operation, a vomit given wilt prevent the fever, which was otherwife to have been expected. See Lino on Fevers and Inspection. 177.] Thefe are advantages to be obtained by exciting vomiting at the firft approach of fevers, or of the parox- yfms of fevers ; and after fevers are formed.; vomiting may alfo be employed to take off, perhaps entirely, the atony and fpafm, or at leaft to moderate thefe, fo that the fever may proceed more gently and fafely. 178.J It is feldom, however, diat vomiting is found to produce a final' folution of fevers ; and after they are once formed, it is commonly neceffary to repeat the vomiting feveral times ; but tins is attended with inconvenience, and fometimes with di fad vantage.. The operation of full vo- miting commonly foon ceafes, and the exercife of vomit- ing is often a debilitating power; and therefore, when the vomiting does not remove the atony and fpafm very entire- ly, it may give occafion to their recurring with greater force. 179.] For thefe reafons,. after fevers are fully formed. phyficians have thought proper to employ emetics jii nau- feating dofes only. Thefe are capable of exciting the ac- tion of the extreme veffels, and their operation is more permanent. At the fame time, they often fhow their pow- er by exciting fome degree of fweat, and their operation is rendered more fafe, by their commonly producing fome evacuation by ftool. l8o.J Such are the advantages to be procured by nau. 8i PRACTICE feating dofes of emetics; and it only remains to mention, what are the medicines moft fit to be employed in that man- ner, what are the moft proper times for exhibiting, and what is the beft manner of adminiftering them. 181.J The emetics at prefent chiefly in ufe, are, Ipeca. cuanha and Antimony. The former may be employed for every purpofe of e- metics, particularly thofe mentioned (172.) It may like- wife be employed, either in larger or fmaller dofes for de- termining to the furface of the body ; but, even in very fmall dofes, it fo readily excites vomiting, as to be with dif- ficulty employed for the purpofe of nau feating only ; and however employed there is reafon to believe, that effeas are lefs permanent, andlefs powerfully communicated from the ftomach to the reft of the fyftem than thofe of Anti- mony. 182.] This therefore, is generally preferred; and its preparations, feemingly various, may all be referred to two heads ; the one comprehending thofe in which the reguline part is in a condition to be aaed upon by acids ; and there- fore, on meeting with acids in the ftomach becomes a£tive ; and the other comprehending thofe preparations in which the reguline part is already joined with an acid, rendering it aaive. 183.] Of each kind there are great numbers, but not differing effentially from one another. It will be enough for us to compare the Calx Antimonii Nirrata of the Edin- burgh Difpenfatory with the Emetic Tartar of the fame. The former, as I judge, is nearly the fame with what is called James's Powder.* Which of thefe is beft fuited to the cure of fevers, as above explained, feems doubtful; but it appears to me, that, although the former may have fome advantages from its flower operation, and may there- by feem to be more certainly fudorific and purgative, yet the uncertainty pf its dofe renders it inconvenient, has of- ten given occafion to the timid to be difappointed, and to the bold to do mifehief. On the other hand, the dofe of the Emetic Tartar can be exaaiy afcertained; and I think * The pulvis antimonialis of the London Pharmacopoeia is intended as a. substitute for, or imitation of, James's powder. The dose of it is 7 or 8 grains. It is by no means so sure in its operations as the emetic tartar; yet it has been Kiuch extolled by several err.inea modern practitioners.

J Whichfoever of thefe preparations be employed, I judge the moft proper time for exhibiting them, to be the time of acceflions; or a little before, when that can be certainly known. In continued fevers, the exacerba- tions are not always very obfervable; but there is reafon to think, that one commonly happens about noon, or foon after it, and another in the evening; and that thefe, there- fore, are the moft proper times for exhibiting emetics. 185.] With refpea to the manner of adminiftiation, that of the Calx Nitrata is fimple, as the whole of what is judged a proper dofe is given at once, and no more can properly be given till the time of the next acceffion.* The adminiftration of the Emetic Tartar is different. It is to be given in fmall dofes, not fufficient to excite vo- miting; and thefe doles, after fhort intervals, are to be repeated for feveral times, till ficknefs, naufea, and fome, but not much, vomiting, come on. The difference of this adminiftration muft depend upon the dofe, and the length of the intervals at which it is given. If it be intend- ed that the medicine fhould certainly operate by ftool, the dofes are made fmall, and the intervals long. On the contrary, when vomiting is proper, or when much purg- ing ought to be avoided, and therefore fome vomiting muft be admitted, the dofes are made larger and the inter- vals fhorter.t 186.] With refpea to both kinds of preparations, the repetition is to be made' at the times of acceffion, but not * The dose is ten or twelve grains. This calx, however, is verv uncertain in its operations, sometimes acting with great violence, and sometimes scarce- ly producing any perceptible effects. f The dose of the Antimonium tartarisatum should never exceed three grains. The best method of giving it is, to dissolve three grains in six oun- ces of water; and of this .mixture give two table spoonsful: if no vomiting ensues within twenty minutes, repeat the dose, and continue to give a table spoonful every ten minutes till the vomiting is excited^ which must be encou- raged by drinking plentifully of camomile tea, or a thin water gtuel. If the emetie tartar be intended for a sudorific, two table spoonsful of the following solution every two or three hours will perhaps be more proper than small doses of the other. R.

PRACTICE very often : for if the firft exhibitions duly managed, have- little effea, it is feldom that the after exhibitions have much ; and it fometimes happens that the repeated vomit- ings, and efpecially repeated purges, do harm by weaken- ing the patient.. 187. J The other fet of internal medicine?, (152. 2) which I fuppofe may be ufeful in taking off the fpafm of the ex- treme veffels, are thofe named Antifpafmodic. How many of thefe may be properly employed, I am uncertain; and their mode of operation is involved in great obfeurity. It is certain, however, that opium,, camphor, mufk, and per. haps fome others, have been employed in fevers with ad- vantage; but the circumftances in which they are efpeci- ally proper and fafe, I find difficult to afeertain; and therefore cannot venture here to lay down any general doc- trine concerning them. 188.] The external means (151.) fuited to take off the fpafm of the extreme veffels, are Blisterln g and Warm. BATHINCr. 1-89.J What are the effeas of Bliftering/fo frequently- employed in fevers, is not yet agreed upon among phyfi- cians; and many different opinions have been maintained on this fubjea, drawn not only from reafoning, but alfo from prefumed experience. I muft not, however, enter into controverfy; but fhall deliver my own opinion in a few words. 190.] I am perfuaded, that the fmall quantity of can- tharides abforbed from a bliftering plafter, is not i'umcient to change the confiftence of the mafs of blood ; and there- fore that fuch a quantity can neither do good, by refolving- phlogiftic lentor, ifitexifts; nor do harm, by increalin^ the diffolution of the blood arifing from a putrid tendency in it. I therefore negfea entirely the effects of cantharides. upon the fluids. 191.] The inflammation produced by the application of cantharides to the fkin. affords a certain proof of their fti- mulant power; but in many perfons, the effeas of that fti- mulus is not confiderable; in many it is not communicat- ed to the whole fyftem; and even when the effect does take place in the whole fyftem, it feems to be taken off en- tirely, by the effufion and evacuation of ferum from the- OF PHYSIC. 87 flittered part. I conclude, therefore, that neither much good is to be expe6ted, nor much harm to be apprehended, from the ftimulant power of bliftering; and the certainty of this conclufion is eftablifhed, by the great benefit arif- ing from the proper praaice of bliftering in inflammatory difeafes. 192.] Much has been imputed to the evacuation occa- fioned by bliftering; but it is never fo confiderable as to a flea the whole f\ item;,and therefore can neither, by fudden depletion, relax the fanguiferous veffels, nor, by any revulfion, affea the general diftribution of the fluids. 193.] The evacuation, however, is fo confiderable as to affea the neighbouring veffels; and the manifeft utility of bliftering near the part affected, i 1 inflammatory dif- eafes, leads me to believe, that bliftering, by deriving to the fkin, and producing an effufion there, relaxes the fpafm of the deeper feated veffels. I apprehend it to be in this manner, that the tumour of a joint, from an effufion into the cellular texture under the fltin, takes off the rheumatic pain affeaing'that joint. -^ 194. J Analagous to this, it may be held, that thetpod effects of bliftering in continued fevers, arife frqpits re- laxing the fpafm of the extreme veffels, by a corrrMhriJca- tion of the bliftered part with the reft of the fkin; armihis is illuftrated by the effea of bliftering in cholic and dylen- tery. 195.] It appears to me, that bliftering may be employ- ed at any period of continued fevers; but that it will be of moft advantage in the advanced ftate of fuch fevers, when the reaaion being weaker, all ambiguity from the ftimu- lant power of bliftering is removed, and when it may beft concur with other circumftances tending to a final folulion of the fpafm. 196.J From the view of this matter given in (193. and 194.) it will appear, that the part of the. body to which bhfters ought to be applied, is indifferent, excepting upon the fufpicion of topical affeaion, when the bliftering ought to be made as near as poffible to the part affeaed. 197.J Whether Sinapisms, and other Rubef acien- ti a, aain a manner analagous to what we have fuppofed ©f bliftering, maybe doubtful; but their effeas in rheu. 88 PRACTICE matifm, and other inflammatory difeafes render it pro- bable. 198.] The other external means of taking off the fpafm of the extreme veffels, is Warm Bathing. This was fre- quently, and in various circumftances, employed by the ancients; but till very lately has been negfeaed by modern phyficians. As the heat of the bath ftimulates the extreme veffels, and, with the concurrence of moiflure, alfo re- laxes them, it feems to be a fafe ftimulus,- and well fuited to take off the fpafm affeaing them. 199.] It may be applied to the whole body by immer- fion; but this is, in many refpe6ts, inconvenient; and whether fome of the inconveniences of immerfion might not be avoided by a vapour-bath, I have not learned from experience. I know, however, from much experience, that moft of the purpofes of warm bathing can be obtained by a fomentation of the legs and feet, if properly admi- nistered, and continued for a due length of time, which ought not to be lefs than an hour. 200.] The marks of the good effeas of fuch fomentati- on, are. the patient's bearing it eafily, its relieving deliri- um, ana inducing fleep. 201.] Having now confidered the feveral means of fatif- fying -the firft general indication in the cure of fevers, I proceed to the fecond(i26.) which is, To remove the cause9 or obviate the effects of debility. 202.] Molt of the fedative powers inducing debility, ceafe to aa foon after they have been firft applied ; and, therefore, the removing them is not an object of our pre- fent indication. There is only one which may be fuppo- fed to aa for a long time ; and that is, the contagion ap- plied : but we know nothing of the nature of contagion that can lead us to any meafures for removing or correa- ing it. We know only its effeas as a fedative power indu- cing debility, or as a ferment inducing a tendency to pu- trefaaion in the fluids. The obviating the latter will be confidered under our third general indication, and the for- mer alone to be confidered here. 203.] The debility induced in fevers by contagion, or other caufes, appears efpecially in the weaker energy of the brain; but in what this confifts, or how it may be di- OF PHYSIC 89 re&ly reftored, we do not well know. As nature, however, does, feemingly for this purpofe, excite the aaion of the heart and arteries, we afcribe the continuance of debility to the weaker reaftion of the fanguiferous fyftem; fo that the means to be employed for obviating debility, are immedi- ately direaed to fupport and increafe the aaion of the heart and arteries; and the remedies ufed are Tonics or Sti- mulants. 204.] In contagious difeafes, both from the effeas which appear, and from diffections, it is known that the tone of the heart and arteries is confiderably diminifhed; and that tonic remedies, therefore, are properly indicated, Thefe are to be confidered as of two kinds; the firft be- ing the power of cold, the fecond that of tonic medicines, 205.J The power of cold, as a tonic, I have mentioned above; (90.) and it is employed, in fevers, in two ways; either as the cold matter is thrown into the ftomach, or as it is applied to the furface of the body. 206. j As it has been fhown above, that the tonic pow- er of cold can be communicated from any one part to eve- ry other part of the fyftem; fo it will readily be allowed, that the ftomach is a part as fit for this communication as any other; and that cold drink, taken into the ftomach, may, therefore, prove an ufeful tonic in fevers. 207.] This the experience of all ages has confirmed; but, at the fame time, it has been frequently obferved, that, in certain circumftances, cold drink, taken into the ftomach, has proved very hurtful; and, therefore, that the ufe of cold drink in fevers requires fome limitations. What thefe limitations fhould be, and what are all the cir- cumftances which may forbid the ufe of cold drink, is dif- ficult to determine; but it feems clearly forbidden, in all cafes where a phlogiftic diathefis prevails in the fyftem, and more efpecially when there are topical affeaions of an inflammatory nature. 208.] The other method of employing cold as a tonic, is, by applying it to the furface of the body. The appli- cation of cold air to the furface of the body, as a refrige- rant power fit to moderate the violence of reaaion, I have fpoken of above; (133.) but probably it may alfo be con. fidered here as a tonic, and ufeful in cafes of debility. Vol. I. M 90 TII A C T 7 C E 209.J Not only cool air, but cold water alfo, may he applied to the furface of the body, as a refrigerant, and perhaps as a tonic. The ancients frequently applied it with advantage, to particular parts, as atonic; but it is a difcovery of modern times, that in the cafe of putrid fe- vers, attended with much debility, the body ma}' be waffl- ed all over with cold water. 210. J This was firft praaifed at Breflaw in Silcfia, as ap- pears from a differtation, under the title of' Epidemia ver- •na quae Wratiflaviam, anno 1737, afflixit, to be found in the appendix-to the Acta. Nat. Curios. Vol. X. And from otlier writers we find, that the practice has.paffed in- to fome of the neighbouring countries; although in tins ifland, fo far as I know, we have hitherto had no experi- ence of it. 211.] The medicines which have been employed in fe- vers, as tonics, are various. If the Saccharum Saturni has been found ufeful, it is, probably, as a tonic, rather than as a refrigerant; and the Ens Veneris, or other pre- parations of iron which have been employed, can aa as tonics only. The preparations of copper, from their ef- feas in epilcpfy, are prefumed to poffefs a tonic power; but, whether their ufe in fevers be founded upon their to- nic or their emetic powers, may be uncertain. The ufe of arfenic and of alum, in intermittent fevers, feems ma- Jiifeftly to depend upon their tonic power. And, upon the whole, there may occur cafes of continued fevers, which may be cured by tonics taken from the foflil king- dom; but the ufe of thefe has been rare, as well as die ef. feas uncertain; and phyficians have employed, more •commonly, the vegetable tonics. 212] A great variety of thefe has been employed in the .cure of intermittent fevers; but how many of them may be •employed in continued fevers, or in what circumftance* of thefe fevers, is not well afcertained; and I fhall now only confider the queftion with refpect to die moft celebrat- ed of thefe tonics, the Peruvian Bark.* * When or how the inhabitants of Peru first discovered the febrifuge pow- ers of this bark is involved in fable and uncertainty. They appear, however, 'to-have long known its virtue, although we have no proofs of rh«ir revealing it to the Europeans before the middle of the last century. The Spaniards OF PHYSIC. ?y 213.] This bark has been commonly confidered as a Specific, or as a remedy of which the operation was net imderftood. Entitis certainly allowable to inquire into this matter; and I apprehend it may be explained.. 214.]- To this purpofe it is to be remarked, that a?, in many cafes, the effeas of the bark are perceived foon af- ter its being taken into the ftomach, and before it can pofi- fibly be conveyed to the mafs of blood, we may conclude, that its effeas do not arife from its operating on the fluids; and muft, therefore, depend upon its operating on the nerves of the ftomach, and being thereby communicated to the reft of the nervous fyftem. This operation feems to be a tonic power, the bark being a remedy in many cafes of debility, particularly in gangrene; and, as the re- currence of the paroxyfms of intermittent fevers depends upon a recurrence of atony, (35. and 36.) fo probably the bark, by it tonic power, prevents the recurrence of thefe paroxyfms; and this is greatly confirmed by obferving, that many other tonic medicines anfwer the fame purpofe. *xll the tree which produces ir Palo de CalcTthirae, orfever tree. Linne calls it Cinchona officinalis, in memory of the Countess of Cinchon, the Spanish viceroy Vlady in Peru, who was the first European thathadbeen cure! by it. It was first brought into J.'ah by n Jesuit about the year 1649, and distributed thnugh Europe by the fathers of that order; hence the names Cortex and Fuiiis Jesxtitiau, Pit his Patrviv. By Cardinal tfe Lv;y's influence a cargo of it was procured and.brought to Home soon after; -whence it received the name of Puhis Carilir.aiis de Lugo. As this bark io a mc.i'uine of considerable importance, it may not be im- proper to join a short description of the external qualities of the best sort. It is in concave pieces, scarcely ever exceeding the fourth part of a cylinder cut longitudinally. It breaks short, and when broken evidently appears to ba composed of three distinct and separate coats, viz. one outer thin coat, tba< is somewhat rugged, often covered with moss of different kinds, and is of a reddish brown color like cinnamon. The middle coat is considerably thicker, of.a ctorer texture and deeper color than the first, and is less brittle but more resinr us than any other part. The third or innermost coat is woody and fi- brous, and hi' a brightish :td, at least considerably brighter than either of tile ethers. From this description of ti>e bark, great care must be taken in pon- dering it, not to leav= much gross powder, but to pass the whole of it through tha sieve, because ths most resinous, and consequently the most effectual, part c.f die bark is the longest and most difficult to powder,. With respect to *he two kinds of bark so much talked of andnoticed a few years ago, it mav be proper to observe, that they seem to be the production of the same tree. The Spaniards always selected such pieces as those above de- scribed out of the original packages, and rejected the thin, pale, and quilled sort, which the English preferred. ft is certain that both the red, pale, quil- led, and a variety of gradation between them, all occur in the sam'e chest as originally imported ; and it is extremely improbable, that the'bark of different kinds of trees should be packed together. Be this matter however as it may, e\perience gives the preference to-what is called the red bark, and ihis sort eight surely to be used. $2 PRACTICE 215,] If the operation of the bark may be thus explain- ed, from its poffeffmg a tonic power, it is eafy to perceive why it is improper when a phlogiftic diathefis prevails; and, from the fame view, we can afeertain in what cafes of continued fever it may be admitted. Thefe are either after confiderable renditions have appeared, when it may be employed to prevent the return of exacerbations, on the fame footing that it is ufed in intermittent fevers, or in the advanced ftate of fevers, when all fufpicion of an inflam- matory ftate is removed, and a general debility prevails in the fyftem; and its being then employed is fufticiently agreeable to the prefent practice. 216.] With refpea to the ufe of the bark, it is proper to add, that good effects are to be expefted from it, almoft only when given in fubftance and in large quantity.* 217.] Another fet of medicines to be employed for ob- viating debility and its effects, are the direct, ftimulants (203.) Thefe, in fome meafure, increafe the tone of the moving fibres; but they are different from the tonics, as more' directly exciting and increafing the action of the heart and arteries. This mode of their operation renders the ufe of them ambiguous; and when an inflammatory diathefis is prefent, as fo often happens in the beginning of fevers, the effects of thefe ftimulants may be very hurt- ful; but it ftill remains probable, that, in the advanced ftate of fevers, when debility prevails, they may be ufeful. 218.] What are the ftimulants that may be moft pro- perly employed, I am uncertain, as the ufe of them in this age has been rare; but I am difpofed to believe that, of all kinds, wine is the beft. 219.] Wine has the advantage of being grateful to the palate and ftomach, and of having its ftimulant parts fo much diluted, that it can be conveniently given in fmall dofes; fo that it maybe employed with fufficient caution; but it is of little fervice, unlefs taken pretty largely.t * The doses of the bark can only be determined from the sta^e of the pati« ent's stomach and the violence of the disease : It is usual to give a drachm of the powder at a dose, and repeat it every two or three hours, according to the exigency of the case, or the state of the patient's bowels. It frequently passes off by stool when given too liberally j this inconvenience is obviated by giving a few drops, 8 or 12 of laudanum, with each dose. f Wine is a valuable cordial, and is much superior to most other stimulants; it raises the pulse, supports the vis vitae, promotes diaphoresis, and resists putrefaction. With respect to the medical differences of wines, it may suf- OT PHYSIC. 93 220.] It may he fuppofed, and on good grounds, that wine has an operation analogous to that of opium, and fome other narcotic medicines. It may indeed be faid, that we can diftinctly mark its ftimulant power only, which renders its effects in the phrenitic delirium manifeftly hurtful, and, in the mild delirium, depending on debility, as remarkably ufeful. But in all this the analogy with opium is ftill obvious; and it is probable, that both wine and opium are more ufeful by their fedative and antifpaf- modic, than by their ftimulant powers. 221.] Thefe are the means of anfwering our fecond ge* neral indication; (126. 2.) and I now proceed to the third, which is, To obviate or to correct the tendency of the fluids to putrefaction. 222.] This may be done, 1. By avoiding any new application of putrid or pu- trefcent matter. 2. By evacuating the putrid or putrefcent matter alrea- dy prefent in the body. 3. By correcting the putrid or putrefcent matter remain- ing in the body. 4. By fupporting the tone of the veffels, and thereby re- filling further putrefaction, or obviating its effects. 223.] The further application of putrid or putrefcent matter may be avoided, 1. By removing the patient from places filled with cor- rupted air. 2. By correcting the air from which he cannot be re- moved. 3. By preventing the accumulation of the patient's own effluvia, by a conftant ventilation, and by a frequent change of bed-clothes and body linen. 4. By the careful and fpeedy removal of all excremen- tal matters from the patient's chamber. 5. By avoiding animal food or correcting it. 224.] The putrid or putrefcent matter, already prefent in the body, may be evacuated partly by evacuating fre- fice to observe that the effects of full bodied wines are more lasting than those of the thinner. Red wines are subastringent, and consequently possess a to- nic virtue, and are hence more proper in fevers of all kinds where wine is at all admissible, than white wines are. All sweet wines are nutritive and in general more stimulating than others ; hut they heat much and are apt to tutu sour on the stomach. $4 P R A CTICE quently the contents of the inteftines,* and more effea ital- \y ftill, by fupporting the excretions of perfpiration and urine, by the plentiful ufe of diluents, f 225.] The putrid or putrefcent matter, remaining in the body, may be rendered more mild and innocent by the ufe' of diluents ; or may be corrected by the ufe of analeptics. Thefe laft are of many and various kinds ; but which of them are conveniently applicable, or more particularly fuit- ed to the cafe of fevers, is not well afcertained. Thofe moft certainly applicable and ufeful, are, acefcent aliments, acids £ of all kinds, neutral falts || and fixed air.£ * The evacuants to be used in these cases are, the mdder purges, s"ch as manna, &c. Rhubarb and senna may also be used ; but we must avoid the drastic purges, such as jalap, scammony, aloes, and similar resinous purges. Calomel has been found very useful in these cases: It may be given to the quantity of 8 or 10 grains, and 3 ounces of the infusum sennx,, with half an ounce of Glauber's salt may be given, about 10 or 12 hours after it,, to accele- ^ rate its operation. ."m. f The diluents necessary in these cases must all be mixt with a little port wine or claret. Warm port wine and water is the best dijuent. ^ Whether all kinds of" acids are to be used as antiseptics is scmewl doubtful. The mineral acids, especially the vitriolic, have been much veco mended; but the vegetable acids seems much more efficacious. As their mildness allows us to give them in very large quantities, and as they r.-.crq easily enter into a union with the animal fluids than the fossile acids do. they s«em more suitable antiseptics i-i these cases. Whether there is any di'I'er- 'ence between *-he native vegetable acids and vinegar, with respect to their antiseptic qu'Jities, was formerly much disputed hv practitioners. Physi- cians, however,, have, now settled this question: and are generally of opinion, that in cases of putrescence arising from fevers, the fermented acid is most pro- per; but in cases if putrescence without fever, they prefer the native acidjuicc3. j) The antiseptic power of the different neutral salts is extremely various. According to the reasoning in the foregoing notf, those consisting of a vege- table acid base ought to be preferred ; and indeed experience confirms tlwe opinion. The Sniritus Mindereri would perhaps be useful, if it could be pre- vented from passing two hastily olFby sweat and urine. In dbses of a drachm every two hours, it is less subject to promote sweat and urine, than when gi- ven in theusual.dose of half an ounce. Lemon juice, saturated with volatile alkali, has often been successfully used in these cases ; especially vhen they arc taken either in the act o£ effervescence,, or separately, the one immediate- ly after the other. § The antiseptic qualities of fixed air are much doubted bv several eminent physicians. The giving it is frequently very difficult, avid sometimes even impossible. The author might have added several other antiseptics to the short list he has given : What he has mentioned, however, are such as are generally used, or appioved of by practitioners. Camphor is a considerable antiseptic, but it is of too heating a quality to be given in such quantities as, seem necessary. The common dose of it is from 1 to 10 grains, and it is best- exhibited in the form of a bolus ; in which form it may also be ioHed wiitL 6ome other antiseptic, as Be- Camphor, gr. viii. Spt.

That the bark may be employed with fafety at any period of intermittent fevers, providing that, at the fame time, there be neither a phlogiftic diathefis prevailing in the fyftem, nor any confiderable or fixed c .ngeftion pre- fent in the abdominal vifcera* 2. The proper time for exhibiting the bark in intermit- tent fevers, is during the time of intermiffion; and where intermiflions are to be expeOed, it is to be abftained from in the time of paroxyfms. 3. In remittents, though no entire apyrexia occurs, the bark may be given during the remiffions; and it fhould be given even though the remiflion mould be inconfidera- ble, if, from the known nature of ihe epidemic, intermiffi- ons or confiderable remilfions, are not to be foon expect- ed, and that great danger is apprehended from repeated exacerbations. 4. In the cafe of £fcnuine intermittents, while a due OF PHYSIC - 99 quantity of bark is to be employed, the exhibition of it outfit to be brought as near to the time of acceffion as the condition of the patient's ftomach will allow. 5. In ^encrat, in all cafes of intermittents, it is not fuffi- cient that the recurrence of paroxyfms be flopped for once by the ufe of die bark ; a relapfe is commonly to be expected, and fhould be prevented by the exhibition of the bark, repeated at proper intervals.* * The quantity of bark to be given in the intermission must be as great as the stomach can pos'-.ibb/ bear. It is very common to give 2 ounces"during the intermission, in doses of half a drachm cr two scruples every hour, espe- cially in quartans. But it has been found more successful in its operations, when we begin with small doses, viz. £)i. in the commencement of the inter- missions, and increase thedo.ses to 51. towards the .end of it. The bark some- times sits better on the stomach by adding to it about an eighth or a fourth of its weight of some aromatic antiseptic. Virginian snake root answers this intention very well. An ounce of red bark and 2 drachms of sna'ke root taken during the intermission of a tertian, if the stomach can bear it, or if no diar- riin a comes on, generally prevents m.: next paroxysm. In»case of diarrhoea being produced by baric, ten or twelve drops of laudanum are tobe given three or four times with each dose of the bark. The substances generally jquied with the bark in prescription, seem calculated either to promote its eScacy or reduce it to the intended form, without having regard to the agreeableness ©flfhe composition. T-his, however, is a point of great consequence, as the ,tmste of the bark, and the large quantity of it accessary for the cure, make th2 patient frequently loath it before its use ought to be discontinued. When made into an electuary cr bolus with syrups, it sticks about the mouth or fauces ; whence its taste remains »■ long while ; bur, when made into an electuary with mucilages, it passes down freely, scarcely leaving any taste behind it. The ta»te of the bark is very effectually concealed by liquorice root in a decoction or by the extract in an electuary. The extract of logwood also conceals the taste of the bark, and an electuary made with it, and a sufficient quantity cf mucilage, is a very elegant form; Decoetions, infusions, and tincture of the bark are much less efficacious than th:- rubstance The extract and the resin aiv seldom employed in the cure of-intermittents, except when other fqrms will not sit on the stomach. The formula in the lz»z London Pharmacopeia is the best, being a compound of both the extract and resin ; for the watery extract is strong in bitterness, butwonk inastringency.and the resin is Wrong in astriagency, .but weak in bitterness, and b<>fh qualities are necessv/\ lor curing intermittents. About 10 or 12 grains of the extract are equivalent to half a drachm of powd'.-r. Whan a paroxysm hns been stopped by the bark, it is by no means safe to abandon the use of this medicine altogether, as a. relapse is alwayr. to be apprehended. The doses are gradually to be diminish- ed, and the intervals between the times of giving them ire to be increased: After tertians, we may diminish the quantity daily one half, tiU we arrive at 2 drachms ; a.id these 2 drachms ought to bfi C*oi.tinned in do;;es of 2 scruples 3 a day for eight days ;. after which period, 2 scruples ought to be given night and morning for a week longer : after quartans, when the dose is reduced to 2 drachm-, a day, it will be prud-'U to continue giving this quantity daily lor a fortnight, and.half a drachm night and mornirig for a fortnight longer. In order the more effectually to prevent a relapse, great attention must be paid to diet and regimen. Patient's are genera".)' extremely voracious after the cure of intermittents ; and indeed they require considerable nutrition to supply the waste occasioned by the fever. Small quantities of food are tobe taken at once and to be often repeated; and the most nutritive, and at the game ti.ae, cosily o^cstabic food, nuul be chosen, x> broths.with barley aal ig© 1'RACTlCE 233. j Our fecond general indication for cor.chrcting the paroxyfms of intermittent fevers, fo as to obtain, a final fo- lution of the difeafe, may be anfwered, 1. By exhibiting emetics during the time of the cold ftage, or at the beginning of the hot. 2. By opiates given during the time of the hot ftage.* 234.J, The circumftances which may efpecially prevent the fulfilling of thofe two indications, and therefore give occaiion to our third, are a phlogiftic diathefis prevailing in the fyftem, and congestions fixed m the abdominal vif- cera.

Where thefe meafures are not immediately effectual, I hold it fafer to attempt the cure of the difeafe by the means pointed out in general in 229. rather than by thofe in ar- ticle fecond of the fame paragraph. *"*<.

Of the Phenomena of Inflammation. 235] VV HEN any part upon the furface of the body- is affeckd with unufual rednefs, heat, pain and tumour, we name the difeafe an Inflammation or Phlegmafia.

With respect to the regimen proper for convalescents from intermittents, it may sufnee to observe, that sleep may be indulged in. Exercise without fatigue is of great use, either bv walking, by riding on horseback, or in a carriage, according to the strength cf the pati- ent. But above all, cold must be carefully avoided ; lor nothing more effec- tually produces a relapse than an imprudent exposure to cold damp air, or a neglect in keeping the bedy properly clothed. The practice of giving purges after the cure of intermittents is highly blameable, and is frequently the <}ause of a rehp-e. Should costive*ness be troublesome, it may be removed by very mild emollient glysters. * This practic of giving vomits in the end of the rold rtage and an opiate after their, operation,:.: eld.

When the blood, after cooling and concreting, fhows a portion of the gluten feparated from the reft of the mafs, and lying on the furface of the craffamentum; as fuch feparation happens in all cafes of more evident phlegmafia; fo, in ambiguous cafes, we, from this appearance, joined with other fymptoms, infer the prefence of inflammation. U the fame time, it muft be obferved, that as feveral cir- cumftances in blood-letting, may prevent this feparation of gluten from Liking place in blood otherwife difpofed to it; fo, from the abfence of fuch appearance, wc cannot always conclude againft the prefence of inflammation. 238.J I cannot eafily give any other general hiftory of the phenomena of inflammation than what is contained in the three preceding paragraphs; and the variations which may take place in its circumftances, will occur to be more properly taken notice of under the feveral heads of the particular genera and fpecies to be hereafter mentioned. I proceed, therefore, to inquire into the proximate caufe of inflammation in general. Sect. II. Of the Proximate Cause of Inflammation. 239.] The phenomena of inflammation (235.) all con- cur in fhowing, that there is an increafed impetus of the blood in the veffels of the part affected; and as, at the fame time, the a£tion of the heart is not always evidently in- creafed* there is reafon to prefume, that the increafed im- Swieten, and most practical writers. It must not, however, be indiscrimi- nately used. It i; seldom attended with any salutary effect, except in vernal intermittents, and in the earlier period of the disease ; and it is constantly attended with disadvantage when the disease, has been of ion^ continuance. 102 PRACTICE petu > of the blood in the particular part is owing efpecially to the increafed action of the veffels of that part itfelf. 240.] The caufe of this increafed action in the veffels of a particular part is, therefore, what we are to confider as the proximate caufe of inflammation. In many cafes, we can mjmifeftiy perceive, that inflam- mation arifes from the application of ftimulant fubftances to the part. When the application of fuch ftimulaniSj dierefore, is evident, we feek for no other caufe of inflam- mation;, but as, in many cafes, fuch application is nei- ther evident, nor, widi any probability, to be fuppofed, we muft, in fuch cafes, feek for fome other caufe of die increafed impetus of the blood in the veffels of the part. 241.] Many phyficians have fuppofed^ that an obftruc- tion of the extreme veffels, any how produced, may prove a caufe of inflammation ; and particularly, that this may arife from an obftruction formed by a matter flopping up thefe veffels. But many difficulties attend this doctrine* 1. The opinion feems chiefly to have arifen frcm the appearance of the blood defcribed in (2.37.) when the fepa- rated gluten was confidered as a preternatural and morbid matter; but we now know very certainly, that this gluten. is conftantly a conftituent part of the human blood; and that it is "only a peculiar feparation of the parts of the blood that happens in confequence of inflammation and fome other circumftances, which gives occafion to the appear- ance that was falfely confidered asa mark of a morbid lentor in the blood. 2. There are no experiments directly in proof of a pre- ternatural lentor prevailing in the mafs of blood; nor is there any evidence of certain parts of the blood oceafion- ally acquiring a greater denlity and force of cohefion than ordinary; neither is there any p.-oof of the denier or more coherent parts being prefent in the mafs of blood, in fuch greater proportion than ufual, as to occafion *a dangerous fpiflitude. The experiments of Dr. Browne Langiifh on this fubjeft afford no conclufion, having been made on certain parts of the blood feparated from the reft, without * This is the Boerhaavian doctrine which the author, here refa'ts, manv objections might be made against several parts of this refutation; but to ex- amine it minutely, is foreign to my purpose, and would require i.icic rocja than the narrow limits of these notes can possibly allow. Or PHYSIC. 103 attending to the circumftances of blood-letting, which very much alter the ftate of the feparation and concretion of the blood drawn out of the veins. 3. The fuppofition of a preternatural lentor or vifcidity of the blood, is not well founded ; for it is probahle, that nature has fpecially provided againft a ftate of the fluids, fo incompatible with the exercife of the moft important func- tions of the animal economy. While motion continues to prevent any feparation of parts, and heat continues to pre- ferve the fluidity of the mo*e vifeid, there feems to be al- ways fo large a pfoportion of water prefent as to give a fufficient fluidity to the whole. I muft own that this is not abfolutely conclufive; but I ftill repeat it, as giving a probability to the general argument. 4. In the particular cafe of inflammation, there are fe- veral circumftances which render it probable that the blood is then more fluid than ufual. 5. I prefume that no fuch general lentor, as Boerhaave and his difciples have fuppofed, does ever take place; be- caufe if it did, it muft mow more confiderable effects than k commonly appear. 6. Befides the fuppofition of an obftrucfing lentor, phy- ficians have fuppofed, that an obftruction may be formed by an impermeable matter of another kind, and that fuch anobftruftionmay alfo be the caufe of inflammation. This fuppofition is what is well known in the fchools under the title of an error loci ; but it is an opinion that I cannot find to be at all probable : for the motion of the blood in the" extreme veffels is fo weak and flow, as readily to admit a retrograde courfe of it; and therefore, if a particle of blood fhould happen to enter a vcffel whofe branches will not allow of its paflage, it will be moved backwards, till it meet with a vefTel fit for tranfmittingit; and the frequent ramifications and anaftomofes of the extreme arteries are very favourable to this. I muft own indeed, that this ar- gument is not abfolutely conclufive ; becaufe I allow it to bg pretty certain that-an error loci, does actually upon occafion happen ; but for, the reafons I have given, it is probable that it feldom happens, and is therefore rarely the caufe of in.Manimation \ orif it be3 that it is not merely by 104 ? R AC i'lCE the obftru&ion that it produces; as, among other reafons, I conclude particularly from the following argument. 7. Though an obftruftion fhould be fuppofed to take place, it will not be fufficient for producing the effects, and . exhibiting the phenomena, that appear in inflammation. The theory that has been commonly employed on this occafion is by no means fatisfying ; and, in fact, it appears, from many obfervations and experiments, that confiderable ob- ftruttions may be formed, and may fubfift, without produc- ing the fymptoms of inflammation. 242.J Obftruction, therefore, from a matter flopping up the veffels, Gaub. Pathol. 249. 1. is not to be confi- dered as the primary caufe of inflammation ; but at the fame time, it is fuificicntly probable, that fome degree of ob- ftrufction does take place in every cafe of inflammation. The di (tenfion, pain, rednefs and tumour, attending in flam* mation, are to be explained only by fuppoting, that the ex- tremities of the arteries do not readily tranfmit the unufu- al quantity of blood impelled into them by the increafed action in the courfe of thefe veffels. Such an obftru6tion may be fuppofed to happen in every cafe 'of an increafed impetus of the blood ; but it is probable, that in the cafe ' of inflammation, there is alfo a preternatural refiftance to the free paffage of the fluids. 243.] From thedoBrine of fever, we are led to believe, that an increafed action of the heart and arteries is not fupported for any length of time'by any other means than a;fpafm affecting the extreme veffels; and that the fpafm takes place in inflammation feems likely, becaufe that eve- ry confiderable inflammation is introduced by a cold ftage, and is accompanied with that and other circumftances of pyrexia. It feems alfo probable, that fomething analo- gous to this occurs even in the cafe of thofe inflammations which appear lefs confiderable, and to be purely topical. 244.] From all this, the nature of inflammation may in many cafes be explained in the following manner. Some caufes of inequality in the diftribution of the blood may throw an unufual quantity of it upon particular veffels, to which itmuftneceffarily prove a ftimulus. But, further, it is probable, that, to relieve the congeltion, the vis me- dicatrix naturae increafes ftill more the aclion of thefe vcf- 0 F P H Y S I C. 105 f Is; and which, as in all other febrile difeafes, it effeas by the formation of a fpafm on their extremities. 245.] A fpafm of the extreme arteries, fupporting an increafed action in the courfe of them, may therefore be confidered as the proximate caufe of inflammation; at leaft, in all cafes not arifing from direct ftimuli applied; and even in this cafe the ftimuli may be fuppofed to produce a fpafm of the extreme veffels. 246. j That, in inflammation, there is the concurrence of a conftriction of the exlfeme veffels, with an increafed a6tion in the other parts of them, feems probable, from the confideration of Rheumatifm. This is a fpecies of inflam- mation which is often manifeftly produced, either by cold applied to over diftended veffels, or by caufes of 'an in- creafed impetus, and over diftention in veffels previoufly conftncled. Hence the difeafe efpecially appears at fea- fons liable to frequent and confiderable viciflitudes of heat and cold. To this we may add, that the parts of the body moft frequently affefted with inflammation, are thofe expofed, both to over diftention, from a change in the diftribution of the fluids, and, at the fame time, to the immediate ac- tion of cold. Hence, quinfies, and pneumonic inflamma- tions, are more frequent than any others. 247. j That a fpafm of the extreme veffels takes place m inflammation, is to be further prefumed from what is at the fame time the ftate of the whole arterial fyftem. In every confiderable inflammation, though arifing in one part only, an affeaion is communicated to the whole fyf- tem, mconfcquenceofwhichan inflammation is readily produced in.other parts befide that firft affeaed. This' general affeaion is well known among phyficians, under the name of the Diathesis Phlogis*ica. It appears moft commonly in perfons of the moft rigid fibres: is of- ten manifeftly induced by the tonic or aftringent powers 0. cold ; is increafed by all tonic and ftimulant powers ap- plied to the body ; is always attended with a hardnefs of the pulfe; and is moft effeaually taken off by the relat- ing power of blood-letting. From thefe circumftances, it feems probable, that the diathefis phlogiftica confifts in an increafed tone, or contraaility, and perhaps in an increa- V 0 L« 1% r\ 1&5 -P R AG T I C E fed-contraction of the mufcular fibres of the whole arteri- al fyftem. Such a ftate of the fyftem feems often to arife, and fubfift for lomc time, without the apparent inflamma- tion of any particular part; but fuch a Jlate of the fyftem renders it likely, that a fpafm may arife in any of the ex- treme veffels, and a particular inflammation be there pro- duced. It does, however, appear alfo, that the general diathefis frequently arifes from inflammation begun in a particular part. 248.] I have thus endeavored, in the cafe of inflamma- tion, to explain the ftate of the whole fyftem, as well as that of-the part more particularly affeaed. The latter I have confidered as when in its firft formation ; but after it has fubfifted for fome time, various changes take place in the part affeaed; and of thefe I muft now take notice. Of the Terminations of Inflammation. 249.] IF an inflammation be cured while the ftate and texture of the part remain entire, the difeafe is faid to be terminated by Resolution. This happens v.7hen the previous congeftion and fpafm have been in a moderate degree, and the increafed impetus of the blood has been fufficient to overcome the fpafm, to dilate the veffels and to remove the congeftion fo that the part is reftored to its ordinary and healthy ftate, A refolution takes place alfo when the increafed impe- tus of the fluids has produced an increafed exhalation into the adjoining cellular texture, or an increafed excretion iri fome neighbouring part, and has thereby relaxed the fpafm, and relieved the congeftion, in the veffels of the part'more particularly affeaed. Laftly, A refolution may take place, when the increaf- ed impetus of the blood in the whole fyftem occafions an evacuation, which, though in a diflant part, may prove fuf- ficient to take off the phlogiftic diathefis of the whole fyf- tem, and thereby relieve the congeftion and fpafm of the particular part affeaed by inflammation. 250.] The tumour which appears in inflammation may be imputed in part to the congeftion of fluids in their proper OF physic. ior vefTels; but is owinq; chieflv to an effufion of matter into the adjoining cellular texture ; and. accordingly, tumours feldoni appear but in parts adjoining to a lax cellular texture. If, in this cafe, the matter effufed be only a larger quantity of the ordinary exhaling f!aid. this, when the free circulation in the veffels is reftored, will be readily abforbed, and the ftate of the part will become the fame as before. But, if the increafed impetus of the blood in an inflamed part, dilate the exhalent vc'ifels to fuch a de- gree, that they pour out aa entire ferum, this will not be fo readily reabfbrbed : ana, from the experiments of Sir John Pringle, and efpecially from thofe of Mr. Gaber, Miscell. Taurin. Vol. II. we learn, that the ferum, under ftagnation, may fuffer a particular change, by having the gluten prefent in it changed into a white opaque, moderate- ly vifeid, mild liqour, which we name Pus. When this change takes place in the inflamed part, as it is at the fame time attended with an abatement of the-rednefs, heat, and pain, which before diftinguifhed the inflammation, fo the difeafe i-s faid to be terminated by £u p?u rat ton ; and an inflamed part, containing a colfeaion of pus is called an Abscess. 251.J In inflammation, the tendency of it to fu ppurati- on may be difcovered by the long continuance of the in- flammation, without the fymptoms of refolution ; by fome remiflion of the pain of diftention; by the pain becoming a throbbing kind, more diftinaiy connected with the pui- fation of the arteries; by the pulfe of the arteries being ful- ler and fofter; and often by the patient's being frequently affeaed with cold fhiverings. The period at which this takes place is not determined, but may fometimes fooner, fbmctimes later. When the tendency is determined, the time neceffary to complete fuppuration is different in dif- fer en.: cafes. When pus is completely formed, the pain in the part en- tirely ceafes, and a weight is felt in it. If the collection be formed immediately under the (kin,the tumour becomes pointed, the part becomes foft, and the fluci nation of the fluid within can commonly be perceived; while at the fame time, for the moft par.t, the rednefs of the fkin formerly prevailing is very much gone, 108 PRACTICE 252.] In abceffes, while the pus is formed of one part of die matter which had been effuied,the other and thinner parts are reabforbed, fo that in the abfcefs, when opened, a pus alone appears. Thus pus, however, is not the con- verted gluten alone : for the converfion of this being the effea of a particular fermentation, which may affea the folid fubftance of the part, and perhaps every folid of ani- mal bodies; fo it moft readily, and particularly, affeas the cellular texture, eroding much of it, which thereby be- comes a part of the pus. It generally happens alfo, that fome of the fmaller red veffels are eroded, and thereby fome red blood often appears mixed with the pus in abfeef- fes. Upon the whole, the internal fuiface of an abfcefs is to be confidered as an ulcerated part. 253-] This account of fuppuration explains, why an ab- fcefs, when formed, may either fpread into the cellular texture of the neighboring parts; or by eroding the incum- bent teguments, he poured out upon the furface of the bo- dy, and produce an open ulcer. 254«] We have here given the idea of an abfcefs as a col- leftion of matter following inflammation; but the term has been applied to every colfeaion of matter effufed, and changed by ftagnatiou in an enclofed cavity. , The matter of abfeeffes, and of the ulcers following them is various, according to the nature of what is effufed, and which may be, 1. A matter thinner than ferum. 2. An entire and pure ferum. 3. A quantity of red globules. 4. A matter furnifhed by particular glands feated in the part. 5. A mixture of matters from different fources, changed by peculiar fermentation. It is the fecond only which affords a proper pus; the ef- fufion whereof, whether in fuppurating parts or ulcers, feems to be the peculiar effea of an inflammatory ftate of the veffels; and for this reafon it is, that, when ulcers do not produce a proper pus, a circumftance always abfolute. iy neceffary to their healing, we in many cafes, bring the ulcers to a ftate of fuppuration, by the application of ftir © F P H Y S I C. 109 mulants exciting inflammation, fuch as balfams,.mercury, copper, Sec. 255-J When the matter effufed in the cellular texture of an inflamed part, is tainted with a putrid ferment, this produces in the effufed matter, a ftate approaching more or lefs to that of putrefaaion. When this is in a moderate degree, and affects only the fluids effufed, with the fub- ftance of the cellular texture, the part is faid to be affeaed with Gangrene ; but if the putrefa6tion affea alfo the veffels and mufcles of the part, the difeafe is faid to be a Sphacelus. 256-j A gangrene, and its confequences, may arife from a putrid ferment diffufed in the mafs of blood, and poured out with the ferum effufed, which it operates upon more powerfully while the ferum is ftagnant, and retained in the heat of the body : but it may alfo arife from the peculiar nature of the matter effufed being difpofed to putrefaaion ; as particularly feems to be the cafe of the red globules of the blood effufed in a large quantity. In a third manner alfo, a gangrene feems frequently to arife from the violent ex- citement of the inflammation deftroying the tone of the veffels ; whereby the whole fluids ftagnate and run into putrefaaion, which taking place in any degree, deftroysftill further the tone of the veffels, and fpreads the gangrene. 257.} In inflammation, the tendency to gangrene may be apprehended from an extreme violence of pain and heat in the inflamed part, and from a great degree of pyrexia attending the inflammation. The aaual coming on of gangrene may be perceived by the color of the inflamed-part changing from a clear to a dark red; by blifters arifing upon the part; by the part becoming foft, flaccid, and infenfible ; and by the ceafing of all pain while thefe appearances take place. As the gangrene proceeds, the color of the part becomes livid, and by degrees quite black; the heat of the part en- tirely ceafes; the foftnefs and flaccidityof the part increafe; it lofes its confiftence, exhales a cadaverous frriell,and may- then be confidered as affected with fphacelus. 258.] Gangrene is thus a third manner in which inflam- mation terminates; and the fchools have commonly mark- ed a fourth termination of inflammation; which is, by a no PRACTICE fcirrhus, or an indolent hardncfs of the part formerly ai- feaed with inflammation. This however, is a rare occur- rence, and does not feem to depend fo much upon the na- ture of inflammation, as upon the circumftances of the part affected. It is in glandular parts chiefly that feirrhofity is obferved ; and it is probably owing tothe parts readily ad- mitting aftagnation of the fluids. I have obferved, that inflammation feldom induces fcirrhus ; but that this lnore commonly arifes from'other caufes; and when inflamma- tion fupervenes, which it is fooner or later apt to do, it does not fo commonly increafe, as change the feirrhofity into fome kind of abfcefs. From thefe confederations it does not feem ncceffary to take any further notice of fcirr- hus as a termination of inflammation. 259.] There are, however, fome other terminations of inflammation, not commonly taken notice of, but now to be mentioned. One is, by the effufion of a portion of the entire mafs of blood, either by means of rupture cr of anaflomofis, into the adjoining cellular texture. This happens efpecially in inflammations of the lungs, where the effufed matter, by compreffmg the veffels and flopping the circulation, oc- cafions a fatal fuffocation ; and this is perhaps the manner in which pneumonic inflammation moft commonly proves fatal. 260.] Another kind of termination is, that of certain inflammations on the furface of the body, when there h poured out under the cuticle a fluid, which being too grofs to pafs through its pores, therefore feparates it from the fkin, and raifes it up into the form of a veficle'containing the effufed fluid ; and by which effufion the previous in- flammation is taken off. 261.] Befide thefe already mentioned, I believe there is ftill another manner in which inflammation terminates. When the internal parts are affeaed with inflammation^ there feems to have been almoft always upon their furface, an exudation, which appears partly asavifeid concretion upon their furface; and partly as a thin ferous fluid effufed into the cavities in which the inflamed vifcera are placed. Though we have become acquainted with thefe appearand ces only, as very conftantly accompanying thofe iidlaai- Oh PHYSIC. Ill Tnations which have proved fatal, it is however probable, that like circumftances may have attended thofe which were terminated by refolution, and may have contributed to that event. It is in favour of this fuppofition that there are inftances of pneumonic inflammation terminating in a hy- drothorax. Sect. IV. Of the Remote Causes of Inflammation. 262.J THE remote caufes of inflammation may be re- duced to five heads. l. The application of ftimulant fubftances; among which are to be reckoned the afction of fire, or burning. 2. External violence operating mechanically in wound- ing, bruiting, compreifing, or ovcrftretching the parts. 3. Extraneous fubftances, lodged in any part of the bo- dy, irritating by their chemical acrimony or mechanical form, or compreifing by their bulk or gravity. 4. Cold, in a certain degree, not fufficient immediately to produce gangrene. 5. An increafed impetus of the blood determined to a particular part. It will not be difficult to underftand how thefe remote caufes, fingly, or in concurrence, produce the proximate caufe of inflammation. 263.] It does not appear, that in different cafes of in- flammation, there is any difference in the ftate of the prox- imate caufe, except in the degree of it; and though fome difference of inflammation may arife from the difference of the remote caufes, yet this is not ncceffary to be taken notice of here; becaufe the different appearances which attend different inflammations may be referred, for the moft part, to the difference of the part affeaed; as will appear when we fhall confider the feveral genera and fpecies mark- ed in the Nofology. When I come to treat of thefe, I fhall find a more proper occafion for taking notice of the different ftates of the proximate, or of the differences of the remote caufe, than by treating of them in general here. 112 PRACTICE Sect.V. Of the Cure of Inflammation. 264.] THE indications of cure in inflammation are dik ferent, according as it may ftill be capable of refolution, or may have taken a tendency to the feveral other termi- nations above mentioned. As the tendency to thefe ter- minations is not always immediately evident, it is always proper, upon the firft appearance of inflammation, to at- tempt the cure of it by refolution. For this purpofe,- the indications of cure are, 1. To remove the remote caufes, when they are evi- dent, and continue to operate. 2. To take off the phlogiftic diathefis affeaing either the whole fyftem, or the particular part. 3. To take off the fpafm of the particular part, by re- medies applied either to the whole fyft.em, or to the part itfelf. 265.] The means of removing the remote caufes will readily occur, from confidering the particular nature and circumftances of the different kinds. Acrid matters muft be removed, or their aaion muft be prevented, by the ap- plication of correctors or demulcents.* Compreifing and overftretching powers muft be taken away ; and, from their feveral circumftances, the means of doing fo will be obvious. 266.] The means of taking off the phlogiftic diathefis of the fyftem, arc the fame with thofe;for moderating the violence of reaBion in fever, which are mentioned and treated of from (127 to 159) and therefore need not be re- peated here. I only obferve, diat in the ufe of thofe re- medies, there is lefs occafion for any referve than in many cafes of fever ; and more particularly, that topical bleed- ingst are here particularly indicated and proper. * If the matter causing the inflammation be an acid, thenthe application of an alkaline substance will be proper: If, on the contrary, the inflammati- on be produced by an alkali, then an acid must be applied. In many cases, however, the acrid substances causing inflammation are neither allialine nor acid ; and, in such cases, or when we cannot find a proper corrector, we must use demulcents, which by their obtunding quality, sheath the acrimony, or defend the parts to which they are applied from being irritated or corroded. f The advantages of topical bleedings, in most cases of local inflammation are very great. They may be performed by cupping, or what is in many ca- ses more preferable, by leeches. Cupping acts sometimes vm« ed, at what period they oughtto be opened, and the manner of opening the:ii| ths> reader can consult no author preferable- to Mr. Bell. JI5 PRACTICE cite the inflammation neceffary on the verge of the living part.* 272.] When the gangrene proceeds from a lofs of tone ; a,nd when this, communicated to the neighboring parts, pi events that inflammation which, as I have faid, is nccef- fary to the feparation of the dead part from the living; it will be proper to obviate this'lofs of tone by tonic medi- cines given internally; and, for this purpofe, the Peruvi- an bark has been found to be efpecially effectual. That this medicine operates by a tonic power, I have endea- I voured to prove above, (214.) and from what is faid in 215. the limitations to be obferved in employing it may al- fo be learned. When the gangrene arifes from the vio- lence of inflammation, the bark may not only fail of prov- ing a remedy, but may do harm: and its power as atonic is efpecially fuited to thofe cafes of grmgrcne which pro- ceed from an original lofs of tone, as in the cafe of palfy and oedema; or to thofe cafes of inflammation where a lofs of tone takes place, while the original inflammatory fymptoms are removed.t * The author mentioned in the preceding note treats this subject in his vi- sual ralional manner, and with n■, -less perspicuity than judgment. Contrary to the cpinion of all former writers on gangrene, he disapproves of scarifica- tions,, and the subsequent replication of antiseptics and stimulants. Mr. Bell's. reasoning against this practice is to the following purport: The degree of in- flaminaion requisite, and indeed necessary, for the separation of the dead parts, is only very flight, and when too violent, it fails to produce ,the desired erlect. Scarifications, and the subsequent application of stimul-nts, which increase the inflammation too much, are therefore hurtful. Again, in scari- fying, there is a considerable risk of wounding large bk>od vessels, nerves, or tendons ; bet-ides the disadvantage of allowing the putrescent fluids of the gangrene to enter more freely the sound parts, by increasing'the surface of the wound. With respect to the application of antiseptics.it is justly remarked, thai although these medicines have the quality of preserving dead animal sub- stances from corruption, they by no means .produce the same effect on living animal substances. But the concluding argument is of much greater weight, \\z. that, in a long course of extensive practice, no advantages ever accrued t from scariiication. These ohjectiens against promiscuous scarification were first proposed by Mr. Bell in his Treatise on Ulcers, about 12 years a.^o ; and the novelty of* the opinion excited the attention of almost every practitioner. At present, however, it is universally adopted, and would of itself, independent of the many improvements Mr. Bell has made in surgery, perpetuate his justly ac- quired fame. f The bark must be given ir> these cases in large quantities ; and as the pulse is in general very small, Port wine mut-t be used along with it. Beside the us.e of those remedies, a good nourishing diet is absolutely requisii.e,with such a quantity of strong generous wine as is fully sufficient to keep up the pulse, and induce the necessary slight degree of inflammation. When indeed the patient is extremely languid, and much reduced, the warm stimulating ' cordials, as camphor, confectio cardiacs, spin'-us ui'jmaticv.i volatilis, SiC. ni.'.y be used with «,dvaritage. OF PHYSIC. 117 573.] The other terminations of inflammation either do not admit of any treatment, except that of preventing them by the means of refolution ; or they belong to a treatife of furgery, rather than to this place. Having thus, therefore, delivered the general doarine, I proceed now to confider the particular genera and fpe-- cies of inflammation. It has been hinted above (263.) that the difference of inflammation arifes chiefly from the difference of the part affeaed : I have therefore arranged them, as they are cu- taneous, visceral, or articular; and in this or- der they are now to be confidered. CHAP. II. ©f 3inflamniattcn, more sttfctlg Cutaneous 274.] V>tUTANEOUS inflammations are of two kinds, commonly diftinguifhed by the names of Phlegmon and Erysipelas. Of the latter there are two cafes, which ought to be dif- tinguifhed by different appellations. When the difeafe is an affeaion of the fkin alone, and very little of the whole fyftem, or when the affeaion of the fyftem is only fympto- matical of the external inflammation, I fhall give the dif- eafe the name of Erythema; but when the external in- flammation is an exanthema, and fymptomatical of an af- fection of the whole fyftem, I fhall then name the difeafe Erysipelas.* 275.] It is the erythema only that I am to'confiderhere. For the di'ftinttion between Erythema and Phlegmon, I have formerly referred to the characters given of them in our Nofology. See Synops. Nosolog. Meth, Vol. II. p. 5. gen. vii. fpec. 1. and 2. But I think it proper now to de- liver the characters of them more fully and exaaiy here, as follows. A phlegmon is an inflammatory affeaion of the fkin, with a fwelling, riling generally to a more confiderable eminence in the middle of it; of a bright red colour; both * The Erysipelas is particularly described in article 6c6, et se^. M* PRACTICE the fwelling and color being prettv exaaiy circumfcribed; the whole being attended with a pain of diftention, often of a ftounding or throbbing kind, and frequently ending in fuppuration. An Erythema, Rofe, or St. Anthony's fire, is an inflam- matory affe6tion of the fkin, with hardly any evident fwel- ling; of a mixed and not very bright red color, readily difappearing upon preffurc, but quickly returning again; the rednefs of no regular circumfeription, but fpreading unequally and continuing almoft conftantly to fpr.ead upon the neighboring part; with a pain like to that from burn- ing; producing bliftcrs, fometimes of a fmall,. fometimes of a larger fize; and always ending in a defquamation of the fearff-fkin, fometimes in gangrene. This fubjeCt I am not to profecute here, as properly be- longing to furgery, the bufinefs of which I am feldom to* enter upon in this.work; and fhall therefore obferve only as neceffary here, that the difference of thefe appearances feems to depend on the different feat of the inflammation. In the phlegmon, the inflammation feems to affea efpecial- ly the veffels on the internal furface of the fkin communi- cating with the lax fubjacent cellular texture; whence a more copious effufion, and that of ferum convertible into pus, takes place. In the erythema, the inflammation feems to have its feat in the veffels on the external furface of the Ik in, communicating with the rete mucofum, which does not admit of any effufion, but what feparates the cuticle, and gives occafion to the formation of a bliftcr, while the fmaller fize of the veffels admits only of the effufion of a thin fluid, very feldom convertible into pus. Befides thefe differences in the circumftances of thefe two kinds of inflammation, it is probable that they alfo dif- fer with refpea to their caufes. Erythema is the effect ®f all kinds of acrids externally applied to the fkin; and, when arifing from an internal caufe, it is from, an acrimo- ny, poured out on the furface of the fkin under the cuticle. In the phlegmon an acrimony is not commonly evident. 276 j Thefe differences in the feat and caufes of the phlegmon and erythema being admitted, it will be evident, that when an erythema affefts any internal part, it can take place in thofe only whofe furfaces are covered with an epU thelion, or membrane analagous to the cuticle. * OF PHY S'lC, 111 277.] The fame diftinciion between the feat and caufes of the two difeafes will, as I judge, readily explain what has been delivered by praaical writers, with refpea to the cure* of thefe different cutaneous inflammations. But I fliall not, however, profecute this here, for the reafon given above; (275.) and, for the fame reafon, fhall not fay anything of the variety of external inflammation, that might otherwife be confidered herc.t chap. in. fl)f Dp&tfjalmia, or Jnflammation of tU Gpe." 278.] JL HE inflammation of the eye may be confider- ed as of two kinds; according as it has its feat in the mem- branes of the ball of the eye, when I would name it Oph- thalmia Mem bran arum ; or as it has its feat in the febaccous glands placed in the tarfus, or edges of the eve- lids, in which cafe it may be termed Ophthalmia Tarsi. Thefe two kinds are very frequently combined together, as the one may readily excite the other; but they are ftill to be diftinguifhed according as one or the other may hap- pen to be the primary affection, and properly as they often arife from different caufes. 279.] The inflammation of the membranes of the eye, affect* efpecially, and moft frequently, the adnata, appear- ing in a turgefcence of its veffels; fo that the red veffels which are naturally there, become not only increafed in fize, but there appear many more than did in a natural ftate. • This turgefeence of the veffels is attended with pain, efpecially upon the motion of the ball of the eye ; and this like every other irritation applied to the furface of the eye, produces an effufion of tears from the lachrymal gland. * The method of curing an erysipelas is delivered in article 708, et sequent. t The cure of erythema is chiefly effected by the antiphlogistic regimen al- ready sufficiently described. Although bleeding, purging, and the general remedies for resolving an inflammation, will in most cases, cure an erythema, yet as ii is a disease frequently depending on a peculiar acrimony, we shall always find great advantage from the external use of emollients applied cold, •r mucilaginous dilueirs taken internally. Ths disease, however, is scldoai dangerous, and generally terminates favorably, 120 T> R A C T I C b This inflammation commonly, and chiefly, affeBs the adnata fpread on the anterior part of the bulb of the eye ; but ufually fpreads alfo along the continuation of that membrane on the infide of the palpebral; and, as that is extended on the tarfus palpebrarum, the excretories of the febaceous glands opening there are alfo frequently affeaed, When the affeaion of the adnata is confiderable, it is fre- quently communicated to the fubjacent membranes of the eye, and even to the retina itfelf, which thereby acquires fo great a fenfibility, that the flighteft imprefhon of light becomes painful. J 280.] The inflammation of the membranes of the eye is in different degrees, according as the adnata is more or lefs affeaed, or according as the inflammation is cither of the adnata alone, or of the fubjacent membranes alfo; and upon thefe differences, different fpecies have been eftablifhed) and different appellations given to them. But I fhall not, however, profecute the confideration of thefe, being of opinion, that all the cafes of the Ophthalmia membranarum | differ only in degree, and. are to be cured by remedies of the fame kind, more or lefs employed. The remote caufes of Ophthalmia are many and vari- ous ; as, 1. External violence, by blows, contufions, and woundsj applied to the eyes; and even very flight impulfes appliedj t whilft the eyelids are open, to the ball of the eye itfelfj. • are fometimes fufficient for the purpofe. 2. Extraneous bodies introduced under the eyelids, ei- ther of an acrid quality, as fmokeand other acrid vapours,* or of a bulk fufficient to impede the free motion of the eyelids upon the furface of the eyeball. 3. The application of ftrong light, or even of a mode- rate light long continued. 4. The application of much heat, and particularly of that with moifture. 5. Much exercife of the eyes in viewing minute ob- jeBs. 6. Frequent intoxication. 7. Irritation from other and various difeafes of the eyes. * Hence chemists, when much.employed in processes where copious noxi- ous vapour* arise, ought to he extremely careful to avoid ihcm as much aa possible. - ____________________'_________________________ OF PHYSIC. 121 8.

A certain confent of the eyes with the other parts of the fyftem, whereby from a certain ftate of thefe parts, either a fimultaneous,or an alternating affeaion of the eyes, is produced. 281. J The proximate caufe of Ophthalmia, is not dif- ferent from that of inflammation in general; and the dif- ferent circumftances of Ophthalmia may he explained by the difference of its remote caufes, and by the different parts of the eye which it happens to affea. This may be underftood from what has been already faid;-and I fhall now therefore proceed to confider the Cure. 282.J In the cure of Ophthalmia, the firft attention will be always due to the removing of the remote caufes, and the various means neceffary for this purpofe will be direa- ed by the confideration of thefe caufes enumerated above. The Ophthalmia membranarum requires the remedies proper for inflammation in general; and when the deeper feated membranes are affected, and efpecially when a py- rexia is prefent, large general bleedings may be neceffary. But this is feldom the cafe; as the Ophthalmia, for the molt part, is an affeaion purely local, accompanied with little or no pyrexia. General bleedings, therefore, from the arm or foot, have little effea upon it; and the cure is chiefly to be obtained by topical bleedings, that is, blood drawn from veffels near the inflamed part; and opening the jugular vein or the temporal artery, may be confider- ed as in fome meafure of this kind. It is commonly fuf- ficient to apply a number of leeches* round the eye; and it is perhaps better ftill to draw blood from the temples, * Ten or twelve may be applied at onee, and when many are employed to- gether, they generally produce a better effect, than if fewer be employed re- peatedly : That is twelve at once are more efficacious than three at a thue re« peated four times a day. Vol. I. Q 122 P R A C T i CTE by cupping and fcarifying.* In many cafes, a very effec- tual remedy is, that of fcarifying the internal furface of the inferior eyelid; and more fo ftill, is cutting the turgid vef- fels upon the adnata itfelf.t 283.] Befidcs blood-letting, purging, as a remedy fuit- ed to inflammation in general, has been confidered as pe- culiarly adapted to inflammations in any of the parts of the head, and therefore to Ophthalmia; and it is fometimes ufeful; but, for the reafons given before with refpea to general bleeding, purging in the cafe of Ophthalmia does not prove ufeful in any degree in proportion to the evacu- ation excited. 284.] For the relaxing the fpafm in the part, and tak- ing off the determination of the fluids to it, bliftering near the part has commonly been found ufeful.J 285.] Efearical fparks taken from the eye will often fuddenly difeufs the inflammation of the adnata: but the effea is feldom permanent, and even a frequent repetition feldom gives an entire cure. 286. j Ophthalmia, as an external inflammation, admits of topical applications. All thofe, however, that increafe the heat and relax the veffels of the part, prove commonly hurtful; and the admiflion of cool air to the eye, the pro- per application of cold water immediately to the ball of ihe eye, and the application of various cooling and aftrin- * Cupping and fcarifying the temples ought to be performed with very great caution, becaufe of the numerous ramifications of conhderable branches of arteries in thofe places. f Thefe operations require great nicety.

They are feldom ferviceable, except they be repeated feveral times. Cutting the veffels of the adnata is perhaps the beft preventive of an opacity of the Cornea that we know : and wherever there is the leaft tendency to an opacity, the praflice fliould be put in execution. The operation ought to be repeated daily for two, three, or four weeks, or even longer, if a cure is not accompliflied fooner. | The part where blilters are ufually applied in ophthalmia are behind the ear, or the nape of the neck. The blilters ought to be kept open by the fub- fequent application of the mild bliftering ointment, if they affume appearances of healing. Setons in the neck are fometimes recommended ; but when fpeedy relief is required, they are of little fervice, becaufe they feldom begin to difcharge till the expiration of a few days ; befides they are extremely troublefome to the patient; and if the phlogiftic diathefis be confiderable, they'fometimes become fo exceedingly inflamed as to produce many difagreeable circumftan- ces that might have been avoided. OF PHY SIC. 123 gent medicines, which at the fame time do not produce much irritation, prove generally ufeful; even fpirituons liquors, employed in moderate quantity, have often been of fervicc* 287.] In the cure of Ophthalmia, much care is requr- fitc to avoid all irritation, particularly that of light; and the only fafe and certain means of doing this, is by confi- ning the patient to a very dark chamber. 288.] Thefe are the remedies of the Ophthalmia mem- branarum; and in the Ophthalmia tarfi, for as it is pro- duced by Ophthalmia membranarum, the fame remedies may be neceffary. As, however, the Ophthalmia tarfi may often depend upon an acrimony depofited in the fe- baceous glands of the part, fo it may require various in- ternal remedies according to the nature of the acrimony in fault; for which I muft refer to the confideration of fero- phula, fyphilis, or other difeafes with which this Ophthal- mia may be conncaed; and when the nature of the acri- mony is not afcertained, certain remedies, more generally adapted to the evacuation of acrimony, fuch, for inftance, as mercury, may be employed.t 289. J In the Ophthalmia tarfi, it almoft conftantly hap- pens, that fome ulcerations are formed on the tarfus. Thefe require the application of mercury or copper, ei- ther of which may by itfelf fometimes entirely cure the * A folution of a fcruple of fugar of lead in four ounces of diftilled water, is a very effectual application ; fome authors recommend equal parts of white vitriol and fugar of lead diffolved in diftilled water. Thefe ccllyria, as they are called, do infinite mifehief if they are too flrong. If, therefore, the patient complains of the leaft fmarting on their applicati- on, it will be neceffary to dilute them with the addition of more diftilled wa- ter. They ought to be applied cold, and pledgets moiftened with them ought tobe frequently renewed when they grow hot or dry. An additional direfti- 011 may be added, viz. that the folution of faccharum faturni be always made with diftillcd water, efpecially when it is to be ufed as a collyrium, becaufe the leaft impregnation of any mineral acid, however combined, decompcfes the fu-^ar of lead. CoLI pouUices of rafped raw potatoes or turnips are fometimes very efEca- ci'ius. They may be applied in a .fine muflin hag, and ought to be renewed whenever they grow warm. t If the ophthalmia be veneral, mercury is the only remedy, and external applications have little effect. If fcrophula is the caufe, relief is often fpeedi- 1 v procured by an application of the Coagulum a luminis, or the unguentum cirrinum, now called unguentum hydrargyri nhratum in the London Pharma- copeia.

J Both in Ophthalmia mc c.branarum, and in the Ophthalmia tarfi, it is neceffary to obviate that gluting or flicking together of the eye-lids which commonly happens in fleep; and this may be done by inlinuating a little of any mild unauous medicines, of fome tenacity, between the eye-lids before the patient fhall go to fleep.* CHAP. IV. 291.] JL HIS difeafe is an inflammation of the parts con- tained in the cavity of the cranium ; a$d may effea either the membranes of the brain, or the fobftance of the brain itfelf. Nofblogifts have apprehended, that thefe two ca- fes might be diftinguifhed by different fymptoms, and there- fore by different appellations : but this does not feem to be confirmed by obfervation and diflectiori; and therefore I fhall treat of both cafes under the title of Phrenzy, or Phrenitis. 292.] An idiopathic phrenzy is a rare occurrence, a fympathic more frequent ; and the afcertaining either one or the other is, upon many occafions, difficult. Many of the fymptoms by which the difeafe is moft commonlyjudg- ed to be prefent have appeared, w hen from certain conii- derations, it was prefumed, and even from diffection it ap- peared, that there had been no internal inflammation; and on the .other hand, diffe6tions have fhown, that the brain had been inflamed, when few of the peculiar fymptoms of phrenzy had before appeared.t 293.] The fymptoms by which this difeafe may be moft certainly known, are a vehement pyrexia, a violent deep- feated headach, a rednefs and turgefcence of the face and eyes, an impatience of light and noiic, a conftant watching * Hog's lard, frefh .preffed lintfeed-oil, or oil of almonds, anfwer this inten- tion very Well, or the unguentum fpermatis ce'ti, of the London Pharmaco- poeia. t This fentence is very obscure; the Author meant to fay, that the diag- nostic fymptoms of this difeafe are uncertain. OF PHYSIC. 125 and a delirium impetuous and furious. Some nofologifts have thought thefe fymptoms peculiar to an inflammation of the membranes, and that the inflammation of the fub- ftance of the brain was to be diftinguifhed by fome degree of coma attending it. It was for this reafon that in the No- fology I added the Typhomania to the charaaerof Phre- nitis; but upon further reflection, I find no proper foun- dation for this; and, if we pafs from the characters above delivered, there will be no means of fixing the variety that occurs. I am here, as in other analogous Cafes, of opinion, that the fymptoms above mentioned of an acute inflammation, always mark inflammations of membranous parts; and that an inflammation of the paronchyma or fubltance of vifce- ra, exhibits, at leaft commonly, a more chronic affeaion. 294.] The remote caufet>f phrenzy, are all thofe which directly ttimulate the membranes or fubftance of the brain; and particularly all thofe which increafe the impetus of the blood in the veffels of the brain. Among thefe the expo- fure of the naked head to the direa rays of a very warm fun, is a frequent caufe. The paffions of the mind, and cer- tain poifons, are amongft the remote caufes of phrenzy ; but in what manner they operate is not well underttood. 295.] The cure of phrenzy is the fame with that of in- flammation in general; but in phrenzy the moft powerful remedies are to be immediately employed. Large and re- peated blood-letting is efpecially neceflary ; and the blood fhould be drawn from veffels as near as poffible to the part affeaed. The opening of the temporal artery has been recommended, and with fome reafon : but the practice is attended with inconvenience ; and I apprehend that open- ing the jugular veins may prove more cffeaual; but at the fame time, it will be generally proper to draw blood from the temples by cupping and fcarifying.* * Prafti doners have in general admitted two kinds of phrexzv, viz. the idiopathic or true phrenzy, and the f> mptomatic. The former is what the Author defcribes in the text; and as he has omitted to defcribe the latter. which in article 292, he acknowledges to be the more frequent of the two, I fhall enumerate its fymptoms. The i'ymptomatic phrenzy is conftantly preceded by feme very acute inflam- matory fever. Its approach may be fufpecled by a fuppreluon of the excreti- ons, by coloilefs ftools, by a black, dry and rough tongue,'by pale and watery urine, which fometimes has black ord'ark brown clouds floating in it, by a de- fire but inability to lleep, by picking the bed clothes, by the eyes appearing 126 * PRACTICE 296.] It is probable, that purging, as it may operate by revulfion, may be of more ufe than in fome other inflam- matory affections. For the fame purpofe of revulfion, warm pediluvia are a remedy ; but, at the fame time fomewhat ambiguous The taking off the force of the blood in the veffels of the head by an creel pofture, is generally ufeful. 297.] Shaving of the head is always proper and ncceffa- ry for the admiflion of other remedies. Bliftering is com- monly ufed in this difeafe, but chiefly when applied near the part affeaed.* 298.] Every part of the antiphl otitic regimen is here neceflary, and particularly the admiflion of cold air. E- ven cold fubftances, applied clofe to the head, have been found fafe and highly ufeful; and the application of fuch refrigerants as vinegar, is certainly proper.t 299.] It appears to me certain, that opiates are hurtful in every inflammatory ftate of the brain; and it is to be obferved, that, from the ambiguity mentioned in (292.) the accounts of prattitioners, with regard to thejuvantia fierce, and the veffels of the albuginea becoming turgid, and by a few drops of blood dialling from the nofe. When moft of thefe fvmptoms appear in inflammatory fever-., we juftly ap- prehend an attack of the phrenzy, and ought to have immediate recourfe to Inch remedies as willleffen its violence, or altogether prevent itsaccefs. Large bleedings, if the pulfe permits muft be made on the lower extremities, cmfl'.i- ent glyfters are to be frequently injefled, laxatives administered, fometimes applied to the feet and legs, cupping glades applied 10 the thighs, and the pa- tient muft be forced to drink plentifully, for he is feldom thirlly in thefe ca- fes, although his tongue be parched. Befide thefe general remedies, peculiar attention muft be paid to the primary difeafe ; and the treatment of the fymp- tomatic phrenzy will vary according to the nature of the difeafe by which it is produced. No part of the practice of phyfic requires more judgment and fagacity in the practitioner, than afcertaining the proper mode of treating the fymptoma- tic phrenzy in different fevers. To enter fully into the fubject, would require more room than thefe notes will allow. I can only therefore recommend the young pratfitioner to pay great attention to it. He will find many ufeful prac- tical direftions for the treatment of thefe cafes, in moft of the medical wri- ters, both ancient and modern, efpecially Sydenham and Van Swieten. * It has been ufual to apply a large bliftering pl'arfter over the whole head, and fuffer it to remain on for eight and forty hours. This, Ivvever, hinders the application of other very powerful remedies. Shaving the head cf a fran- tic patient is always a troublefome operation ; but the very great benefit ari- fing from it, renders it abfolutely neceffary in all cafes; and the phyfician ought therefore to advife it on the firft fufpicion of an approachingphrenzy. f Many eminent practitioners have diffuaded the ufe of thefe refrigerant applications to the newly (haven head; the immediate relief which the mere (ha- ving 2 :..r. lly procures feems to indicate the propriety of the pra&ice : and experience has not difcovered any material difadvantages attending it, but on the contrary, much benefit accruing from it.

V. £>f t&c £tum02, ot Qnanc&e* 300.] X If IS name is applied to every inflammation of the internal fauces; but thefe inflammations are different, according to the part of the fauces which may be affeaed, and according to the nature of the inflammation. In the Nofology, therefore, after giving the charaacr of the Cy- nanche as a genus, I have diftinguifhed five different fpe- cies, which muft here hkewife be feparately confidered. Sect. I. Of the Cynanche Tonsillaris. 301.J THIS is an inflammation of the mucous mem- brane of the fauces, affecting efpecially that congeries of mucous follicles which forms the tonfils,andfpreadingfrom thence clou; the velum and uvula, foas frequently to affect every part of the mucous membrane. 302. J The difeafe appears by fome tumour, fometimes confiderable, and by a rednefs of the parts; is attended with a painful and .difficult deglutition; with a pain fometimes fhooting into the ear; with a troublefome clamminefsof the mouth and throat; with a frequent, but difficult, excre- tion of mucous; and the whole is accompanied with a py- rexia. 303.] This fpecies of quinfy is never contagious. It terminates frequently by refolution,* fometimes by fup- puration, but hardly ever by gangrene; although in difs difeafe fome floughy fpots commonly fuppofed to be fore- runners of gangrene, fometimes appear upon the fauces. 304. J This difeafe is commonly occafioned by cold ex- ternally applied, particularly about the neck. It affects efpecially the young and fan^uir.e, and a difpofition to it is often acquired by habit; fo that from every confiderable * As the moft frequent termination of this difeafe is by refolution, this mode ef cur« mult always be attempted, and will feldom fail of proving fuccefsful. 128 PRACTICE application of cold to any part of the body, this difeafe is readily induced. It occurs efpecially in fpiing and autumn, when viciflitudes of heat and cold frequently take place. The inflammation and tumour are commonly at firft moft confiderable in one tonfil; and afterwards, abating in that, increafe in the other. 395.] In the cure of this inflammation, fome bleeding may be proper: but large general bleedings will feldom be neceffary. The opening of the ranular veins feems to be an infignificant remedy; and leeches fet upon the external fauces arc of more efficacy. 306.] At the beginning of the difeafe, full vomiting has been frequently found to be of great fervice.* 307.J This inflammation may be often relieved by mo- derate aftringents, and particularly by acids applied to the inflamed parts.t In many cafes, however, nothing has been found to give more relief than the vapor of warm water re- ceived into the fauces by a proper apparatus. 308.] The other remedies of this difeafe are rubefaci- ent or bliftering medicines, applied externally to the neck; and with thefe, the employment of antiphlogiftic purga- tives,J as well as every part of the antiphlogiftic regimen, excepting the application of cold. 309. J This difeafe, as we have faid, often terminates by refolution, frequently accompanied with fweating ; which is therefore to be prudently favored and encouraged.|J ( * The formula of an emetic may be feen in the note on art. 185. f Various have been the opinions of phyficians refpecling the kind of gar* gles proper in thefe cafes. A pint of tincture of roles, with two drachms of honey, has often been found ferviceable. The following gargle is frequently ufed with fuccefs. Boil an ounce of oak-bark, bruifed in a quart of water, till half is evaporated, and to the ftrained liquor add an ounce of honey of rc~ fes, and a drachm of allum. Sage tea, with honey, is in common ufe, and frequently anfwers every purpofe. _ | Glauber's Salts anfwer the end of purges in thefe cafes very well, efpe- cially if the patient drinks copioufly during the operation. || Dover's powder is an excellent fudorific in thefe cafes. The method of giving it has been defcribed in a former note, on art. 169. Many other fudo- rifics, however, are found to anfwer tolerably well, as wine-whey, whey made with dulcified fpirit of nitre, vinegar-whey, fage tea, with feveral other drinks ofafimilar kind. The following bolus is often very efficacious, efpecially when the patient drinks largely of fage or balm tea. R. Camphor, gr. viii. Opii pur. gr. i. Tart. Vitriolat. 9i.

I have never had occafion to fee any cafe requiring bronchotomy. Of the Cynanche Maligna. 311.] THIS is a contagious difeafe, feldom fporadic, and commonly epidemic. It attacks perfons of all ages but more commonly thofe in a young and infant ftate. It attacks perfons of every conftitution when expofed to the contagion, but moft read ily the weak and infirm. 312.] This difeafe is ufually attended with a confidera- ble pyrexia ; and the fymptons of the acceffion of this, fuch as frequent cold fhiverings, ficknefs, anxiety, and vomit- ing, are often the firft appearances of the difeafe. About the fame time, a ftiffnefs is felt m the neck, with fome unea- finefs in the internal fauces, and fome hoarfenefs of the voice. The internal fauces, when viewed, appear of a deep red colour, with fome tumour ; but this laft is feldom con- fiderable, and deglution is feldom difficult orpainful. Very foon a number of white or afh coloured fpots appear upon the inflamed parts. Thefe fpots fpread and unite, cover- ing almoft the whole fauces with thick floughs; which falling off, difcover ulcerations. While thefe fymptoms proceed in the fauces, they are generally attended with a Small dofes of tartar emetic taken in fuch quantities as to produce a flight naufea without vomiting, are alfo good fudorifics.

There is often alfo efpecially in infants, a frequent purging; and a thin'acrid matter flows from the anus excoriating this and the neighboring parts. 313. J With thefe fymptoms, the pyrexia proceeds with a fmall, frequent, and irregular pulfe; and there occurs a manifeft exacerbation every evening, and fome r miffion in the mornings- A great debility appears in the animal funaions ; and the fenforium is affeaed with delirium, fre- quently with coma. 314.J On the fecond day, or fometimes later, effloref- cences appear upon the fkin, which are fometimes in fmall points hardly eminent; but, for the moft part, in patches of red colour, fpreading and uniting fo as to cover the whole fkin. The) appear firft about the face and neck, and in the courfe of fome days fpread by degrees to the lower ex- tremities. The fcarlet rednefs is often confiderable on the hands and extremities of the fingers, which feel ftiff and fwelled. This eruption is often irregular, as to the time of its appearance, as to its fteadinef s, and as to the time of its duration. It ufually continues four days, and goes off by fome defquamation of the cuticle ; but neither on its appearance, nor on its difquamation, does it always produce a remiflion of the pyrexia, or of* the other fymptoms. 315.] The progrefs of the difeafe depends on the ftate of the fauces and of the pyrexia. \\ nen the ulcers on the fauces, by their livid and black colour, by the fetor of the breath, and by many marks of acrimony in the fluids, fhow a tendency to gangrene, this takes place to a confiderable de- gree ; and the fymptoms of a putrid fever conftantly in- creafing, the patient dies, often on the third day, fometimes later, but fV the moft part before the feventh. ' The acri- mony poured out from the difeafed fauces muft ncceffari- ly, in part, pafs into the pharynx, and there fpread the in- feaion into the cefophagus, and fometimes through the whole of the alimentary'canal, propagating the putrefaai- on, and ofignexhaufting the patient by a frequent diarrhoea.

From diffeaions it appears, that, in the Cynanche maligna the laryax.and trachea are often'a A feaed in the fame manner as"i4ttl4jpynanche tracheal!*; and it is probable, that, irwcoiMBMfe'of that affeaion, the Cynanche maligna oftcyi proTe!3al hy fuch a fudden fuffocation as happens fyi the proper 6fnanche trachealis; but there is reafon to-fu|pect, that upip^fthis fubjea diffec- tors have not always' diftin^tuifhefl'.jA'operly between the two difeafes. ||, ■ - 316.] Tfiffc are fifec feveral'fatat terminations of the .C/n> anche maligna./and they do not always take place. : Some- > times the ufelT4%f*lne\fauccsvare °f'a milder nature ; ana the fever is mptkmbderate, as }wcjl as of a lefs putrid kind.

From what is faid in this and the preceding paragfaph, tlie prognostics in this difeafe may be readily learneQjjtj 317.] In the cure of this difeafe, its feptic tendenqrfe cheifly to be kept in view. The debility, with which it is attended, renders all evacuations by bleeding and purg- ing improper, except in a few inflanccs where the debility is lefs, and the inflammatory fymptoms more confiderable. The fauces are to be prcferud from the effeas of the acrid matter poured out upon them, and are therefore to be fre- quently waffled out by ami feptic gargles * or injeaions; * When the violence of the iymptoms is moderate, and when the ulceration is (light, fage tea, or tea made of role leaves, or both together, may be fuffi- cient. A gargle made of a pint of fage and rofe tea, three fpoonsful of vine- gar, and one fpoonful of honey, has been fuund as efficacious as any of the fharpcr autifeptics with the mineral acids.

But he often ufed it with a drachm of the Mel Egyptiacum cUfiblved in two ounces of it. The Mel Egyptiacum is a very harfh application, and ought to be cautious- ly ufed. If the Houghs caft off fo flowly as to require a powerful application, it is better practice to touch them with Mel Egyptiacum by means of an arm- ed probe, than to ufe gargles of which it is an .i.yf^^wt. In this difeafe, ftrict attention muft be giyen to the ufe of gargles avii mjl-'lipns for the tliroar, becaufe the cure feems to depend in part on procuring a difcharge from the glands cf the fauces which thefe gargles induce, and alio becaufe they are the only means of retarding the progrefs rjf the ulcers. * The quantity of bark given ought to be very confiderable, viz. as much as the ftomach and inteftines can poflibly bear.; half a drachm or two fcrupU-s every hour, with a glafs of good Port wine. A fcfiJpIe of confeftio cardiaca, joined with each dofe of the bark, has a double effect of making the bark lefs naufeous, and of preventing in fome meafure, a tendency to a diarrhoea, but opium is afovereign remedy fcr removing this fymptom when it is actually prefent. Mjfcdminiftering the bark, great care muft be taken to avoid a diarrhoea, which is a very dangerous fymptom in any period of the difeafe, but efpeci- ally after the third or fourth day, when the patient is in a confiderable ftate of debility. Children are more frequently attacked with this difeafe than adults ; and it is fometimes extremely difficult to prevail on them to take a fufficient quan- tity cf this neceffary and valuable, though naufeous medicine. In thefe ca- fes glyfters with powdered bark have been ufed with very great fuccefs. Two drachms of the fine powder may be given in five or fix ounces of barley-wa- ter, every 3 or 4 hours to very young children, and half an ounce or 6 drachms to children of 8 or 10 years old, in three quarters of a pint of I iilej -water. If the firft glyfter comes away too fpeedily, two or three grains cf opium may be added to the fubfequent glyfters. t In addition to the method of cure here delivered, it may be proper to ob- ferve, that as the cure depends much on the removal of every thing putrid frcm the patient, it is abfolutely neceffary to have the room well ventilated, but not with cold air. The reafon for this precaution is, that the patient al-. wavs^complains of the leaft admiffion of cold air, becoming fick and oppreff- edfprobably in confequence of the fudden difappearance of the efllorcfcence which always accompanies the difeafe. The linen ought frequently to be Changed, the patient kept clean, the mouth and throat frequently waflied, and great plenty of liquid vegetable nutriment mutt be given, with generous wine. A hemorrage from the nofe, mouth, or ears, very frequently occurs in the later ftages of a malignant fore throat. This difcharge is by no means criti- cal, but always a dangerous fymptom, and muft be flopped with the utmoft expedition. It is the confequence cf fome arterial branch being corroded by the mortification. If the hemorrhage withftands the ufual means of tents dip- OF PHYSIC. is* Sect. III. Of the Cynanche Trackballs. 318.] THIS* name has been given to an inflammation of the glottis, larynx, or upper part of the trachea, whe- ther it affect the membranes of thefe parts, or the mufcles adjoining. It may arife firft in thefe parts, and continue to fubfift in them alone; or it may come to affea thefe parts from the Cynanche tonlillaris or maligna fprcading into them. 319.] In either way it has been a rare occurrence, and few inftances of it have been marked and recorded by phy- ficians. It is to be known by a peculiar ringing found of the voice, by difficult refpiration, with a fe de of ftraiten- ing about the larynx, ahd by a pyrexia attending it. 320. J From the nature of thefe fymptoms, and from the diflection of the bodies of perfons who had died of this dif- eafe, there is no doubt of its being of an inflammatory na- ture. It does not, however, always run the courfe of in- flammatory affeaions, but frequently produces fuch an obftruaion of the paffage of the air, as fuffocates, and thereby proves fuddenly fatal. 321.J If we judge rightly of the nature of this difeaft^ it will be obvious, that the cure of it requires the moft pow- erful remedies of inflammation, to be employed upon the very firft appearance of the fymptoms.—When a fuffoca- tion is threatened, whether any remedies can be employed to prevent it, we have not had experience to determine. 32 2. J The accounts which books have hitherto given us of inffammation of the larynx, and the parts conneaed with it, amount to what we have now faid; and the inftaa- ces recorded have almoft all of them happened in adult perfons; but there is a peculiar affection of this kind hap- ped in vinegar, or a folution of alum, 8tc. recourfe muft be had to opium and bark j and the Part wine muft be given fparingly. I;i the advanced ftages, a diarrhcea frequently appears, efpeciallv in chil- dren; it proceeds from the putrid and acrid matter of the ulcers being recei- ved into the inteftines. It can only be prevented, or effectually removed, by a careful attention to keep the mouth as clean as poffible. * This difeafe has been fuppofed to be new, and confined chiefly to infants. It is, however, defcribed by many of both the ancient and modern writers. Boerhaave defcribes it in his 801ft and 8o2d Aphorifin. It is, indeed, uncom- mon in adults, and moft frequent in infants. It was never 1 i0!itly underftood, however, till Dr. Home, the profeffor of the Materia Medha in this Univer- fity, inveftigated its nature, and pointed out the only effectual method of cure. \Zi « PRACIRt pening efpecially to infants, which till lately has been little taken notice of. Dr. Home is the firft who has given any diftina account of it; but, fince he wrote, feveral other authors have taken notice of it, (fee Mien a e i. i s De an- gina polyposa sive membranacea, Argcntorati 1778) and have given different opinions with regard to it. Concern- ing this diverfity of opinions I fhall not at prefent inquire; but fhall deliver the hiftory and cure of this difeafe, in fo far as thefe have arifen from my own obfervation, from that of Dr. Home, and of other fkilful perfons in this, neighborhood. 323.] This difeafe feldom attacks infants till after they have been weaned. After this period, the younger drey are, the more they are liable to it. The frequency of it be- ^ comes lefs as children become more advanced; and there are no inftances of children above twelve years of age being affeaed with it. It attacks children of the midland coun- tries, as wTell as thofe who live near the lea. It docs not ap- pear to be contagious, and its attacks are frequently re- peated in the fame child. It is often manifeftly the effea of cold applied to the body; and therefore appears moft fre- quently in the winter and fpring feafons. It very common- ly comes on with the ordinary fymptoms of a catarrh; but fometimes the peculiar fymptoms of the difeafe fhow die in- felves at the very firft. *. 324.] Thefe peculiar fymptoms are the following; A hoarfenefs, with fome fhrillnefs and ringing found, both in. fpeaking and in coughing, as if the noife came from a bra- zen tube. At the fame time, there is a fenfe of pain about the larynx, fome difficulty of refpiration, with a whizzing found in infpiration, as if the paffage of the air was ftrait- ened. The cough w hich attends it, is commonly dry; and if .rany thing be fpit up, it is a matter of purulent appear- ance, and fometimes films refembling portions of a mem- brane. Together with thefe fymptoms, there is a frequen- cy of pulfe, a reftleffnefs, and an uneafy fenfe of heat. When the internal fauces are viewed, they are fometimes without any appearance of inflammation: but frequently a rednefs and even fwelling, appear ; and fometimes in the fauces there is an appearance of matter like to that rejeaed t by coughing. With the fymptoms now defcribcd and'4* CfF PHYSIC. 135 particularly with great difficulty of breathing, and a fenfe of ftrangling in the fauces, the patient is fometimes fuddenly taken off. 325.] There have been many diffeaions made of in- fants who had died of this difeafe ; and almoft conftantly there has appeared a preternatural membrane lining the whole internal Surface of the upper part of the trachea, and' extending in the fame manner downwards into fome of its ramifications. This preternatural membrane may be eafily feparated, and fometimes has been found feparated in part, from die fubjacent proper membrane of the trachea. This laft is commonly found entire, that is, without any ap- pearance of erofionor ulceration; but it frequently (hows the vcftiges of inflammation, and is covered by a matter refembling pus, like to that rejected by coughing; and very often a matter of the fame kind is found in the bron- enhe. fometimes in confiderable quantity. 326. J From the remote caufes of this difeafe; from the catarrhal fymptoms commonly attending it; from the py- rexia conftantly prefent withit; from the fame kind of pre- ternatural membrane being found in the trachea when the cynanche maligna is communicated to it; and, from lhe veftiges of inflammation on the trachea difcovered upon diffection ; we muft conclude, that the difeafe confifts in an inflammatory affeaion of the mucous membrane of the larynx and trachea, producing an exudation analogous to that found on the furface of inflamed vifcera, and appear- ing partly in a membranous cruft, and partly in a fluid re- fembling pus. 327.] Though this difeafe manifeftly confifts in an in- flammatory affection, it does not commonly end either in fuppuration or gangrene. The peculiar and troublefomc circumftances of the difeafe feems to confift in a fpafm of the mufcles of the glottis, which by inducing a fuffocation, prevents the common confcquences of inflammation. 328.j When this difeafe terminates in health, it is by a refolution of an inflammation, by ceafing of the fpafm of the glottis, by an expeaoration of the matter exuding from the trachea, and of the crufts formed here ; and frequent- ly it ends without any expeaoration, or at leaft with fuch only as attends an_ordinary catarrh. 13$ PRACTICE 329.] When the difeafe ends fatally, it is by a feffoca- tion ; feemingly, as we have faid, depending upon a fpafm * affeaing the glottis; but fometimes, probably, depending upon a quantity of matter filling the bronchiae. 330.] As we fuppofe the difeafe to be an inflammatory affedion, fo we attempt to cure it by the ufual remedies of inflammation, and which for the moft part I have found effeaual. Bleeding, both general and topical,* has often given immediate relief; and by being repeated, has entirely cured the difeafe. Bliftering alfo, near the part affeaed, has been found ufeful. Upon the firft attack of the difeafe, . vomiting, immediately after bleeding, feems to be of con- fiderable ufe, and fometimes fuddenly removes the difeafe. In every ftage of the difeafe, the antiphlogiftic regimen is neceffary, and particularly the frequent ufe of laxative glyfters.t Though we fuppofe that a fpafm affeaing the ' glottis is often fatal in this difeafe, I have not found antif- 1 pafmodic medicines to be of any ufe. Sect. IV. Of the Cynanche Pharyngcea. 331.] IN the Cynanche tonfillatis, the inflammation of the mucous membrane often fprcadsupon the pharynx, and into the beginning of the cefophagus, and thereby renders deglutition more difficult and uneafy : but fuch a cafe does not require to be diftinguifhed as a different fpecies from the common Cynanche tonfillaris; and only requires that blood-letting and other remedies fhould be employed with * The topical bleeding is beft performed by leeches. Three or four may he applied at once on each fide of the trachea, or on the trachea itfelf. Not- ■withftanding this recommendation of topical bleeding, previous general bleed- ing is abfolutely neceffary in every cafe, and ought never to he omitted. It frequently produces relief even while the blood is flowing from the vein; but in thefe cafes, it is imprudent to ftop the evacuation, even on the total removal ©f the fymptoms. As much blood muft be drawn as the infant can bear to lofe, and leeches ought moreover to be applied, as above directed ; for it fre- quently happens, that when all the fymptoms fuddenly difappear, the difeafe returns in a few hours with redoubled violence, and fpeedily puts an end t« the child's life. ^i. f Laxative glyfters are tobe carefully diftinguifhed from purging glyfters^jjB ■which generally irritate too violently, and thus increafe the inflammatory dWBH athefis.

We have never feci any cafe in which the inflammation began in the pha- rynx, or in which this part alone was inflamed ; but prac- tical writers have taken notice of fuch a cafe ; and to them therefore, I muft refer, both for the appearances which dif- tinguifh it, and for the method of cure. Sect. V. Of the Cynanche Parotideza. 332.] Tins is a difeafe known to the vulgar, and among them has got a peculiar appellation, in every country of Europe * ; but has been little taken notice of by medical writers. It is often epidemic, and manfeftly contagious. It comes on with the ufual fymptoms of pyrexia, which is foon after attended with a confiderable tumour of the ex- ternal fauces and neck.—This tumour appears firft as a glandular moveable tumour at the corner of the lower jaw ; but the fwelling foon becomes uniformly diffufed over a great part of the neck, fometimes on one fide only, but more commonly on both. The fwelling continues to in- creafe till the fourth day ;^ut from that period it declines, and iii a few days more panes off entirely. As the fwclliiw, of the fauces recedes, fome tumour affects the tefticlcs in the male fex, or the brcafts in the female. Thefe tumours are fometimes large, hard, and fomewhat painful; but in this climate are feldom either very painful or of long con tinuance. The pyrexia attending this difeafe is common- ly flight, and recedes with the fwelling of the fauces ; but fometimes, when the fwelling of the telticles does not fuc- cced to that of the fauces, or when the other has been fud- denly repreffed, the pyrexia, becomes more confiderable, is often attended with delirium, and has fometimes proved fatal. 333.] As this difeafe commonly runs its courfe without either dangerous ortroublefome fymptoms, foit hardly re- quires any remedies. An antiphlogiftic regimen and avoid- ing cold, arc all that will be commonly neceffary. But when, upon the receding of the fwelling of the telticles in males, of of the brcafts in females, the pyrexia comes to be * * It is called here, and in many parts »f Great-Britain, the Mii:!"(> Vol. 1.

CHAP. VI. flDf Pneumonia, or Pneumonic inflammation. 334-] UNDER this title I mean to comprehend the whole of the inflammations affeaing either the vifcera of the thorax, or the membrane lining the interior furface of that cavity : for neither do our diagnostics ferve to afeer- tain exaaiy the feat of the difeafe ; nor does the difference in the feat of the difeafe exhibit any confiderable variation in the ftate of the fymptons, nor lead to any difference in the method of cure. 335.] Pneumonic inflammation, however various in its feat, feems to me to be always known and diftinguifhed by "* J the followingfymptoms: pyrexia, difficult breathing, cough and pain in fome parts of the thorax. But thefe fymp- toms are, on different occasion^ varioufly modified. 336.] The difeafe almoft always comes on with a cold ftage, and is accompanied with ether fymptoms of pyrex- ia ; though, in a few inftanccs, the pulfe may not be more frequent, nor the heat of the body increafed bevond what is natural.- Sometimes the pyrexia is from the beginning accompanied with the other fymptoms ; but frequently it is formed for fome hours before the other fymptoms be- come confiderable, and particularly before the pain be felt. For the moft part, the pulfe is frequent,* full, ftrong, hard, and quick ;t but in a few inftances, efpecially in the advan- ced ftate of the difeafe, the pulfe is weak and foft, and at the fame time irregular. 337.] The difficulty -of breathing is always prefent, and tnoft confiderable in infpiration; both becaufe the lungs do * A frequent pulfe is when there is a great number of ftrokes in a given ^B time.

The difficulty of breathing is alfo greater when the patient is in one pofture of his body rather than another. It is generally greater when he lies upon the fide affected; but fometimes the contrary happens. Very often the patient cannot lie eafy upon either fide, finding cafe only vhen lying on his back; and fometimes he cannot breathe eafily, except when in fomewhat of an erea pofture. 338. ] A cough always attends this difeafe; but in differ- ent cafes, is more or lefs urgent and painful. It is fome- times dey, that is without any expeaoration, efpecially in the beginning of the difeafe : but more commonly it i:g even from the firft, moift, and the matter fpit up various both in conhftence and colour; and frequently it is ftreaked with blood.* 339-J The pain attending this difeafe, is in different cafes, felt in different parts of the thorax, but moft frequently in one fide. It has.been faid to affea the right fide more frequently than the left; but this" is not certain ; while on the other hand, it is certain that the left lias been very often affeaed. Tire pain is felt fometimes as if it were under the fternum ; fometimes in the back between the fhoulders ; and when in the fides, its place has been higher or lower,. more forward or backward : but the place of all others moft frequently affeaed, is about the fixth or feventh rib, near the middle of its length, or a little more forward. The pain is often f'evere and pungent;, but fometimes more dull and obtufe, with a fenfe of weight rather than of pain. It is moft efpecially fevere and pungent when occupying the place laft mentioned. For the moft part it continues fix- ed in one place ; but fometimes fhoots from the fide to the fcapula on one hand, or to the fternum and clavicle on the other. 340.] The varying ftate of fymptoms now mentioned docs not always a {'certain precifely the feat of the difeafe:* To me it feems prohable, that the difeafe is always feated, ar at leaft begins, in fome part of the pleura ; taking that * Young pradlitioners fliould not be alarmed at this fymptom; nor fliould they fuppofe it a dangerous one : it is on the contrary a falutary fymptom, and ought not to be rcftrained, c itlier by too rigorous an adherence to tha Jin* tiphlogiftic regimen, sr by ihe ufe of ftvptics au.i c-tlv;r aftringeuts. 140 PRACTICE membrane in its greateft extent, as now commonly under- stood ; that is, as covering not only the internal luvfacc ot the cavity of the thorax, but alfo as forming the mediafti- num, and as extended over the pericardium, and over the whole furface of the lungs. 341.] There is, therefore, little foundation for diftin- guilhing this difeafe by different appellations taken from the part which may be fuppofed to be chcifly affected. The term Plcurify, might v/ith propriety be applied to every cafe of the difeafe ; and has been very improperly limited to that inflammation which begins in, and cheifiy affects the pleura costalis. I have no doubt that fuch a cafe does truly occur : but, at the fame time, I apprehend it to be a rare occurrence; and that the difeafe much more frequently begins in, and chiefly affc&s, the pleura inventing the lungs, producing all the fymptoms fuppofed to belong to what has been called the Pleuritis vera. 342.] Some phyficians have imagined, that there is a cafe of pneumonic inflammation particularly entitled to the apellation of Peripneumony ; and that is, the cafe of an inflammation beginning in the parenchyma or cellular tex- ture of the lungs, and having its feat chiefly there. But it feems to me very doubtful, if any acute inflammation of the lungs or any difeafe which has been called Peripneumony be of that kind. It feems probable, that every acute in- flammation begins in membranous parts; and, in every diffie£tion of perfons dead of peripneumony, the external membrane of the lungs, or fome part of the pleura, has appeared to have been confidcrably affeaed- 343.] An inflammation ofthe pleura covering the upper furface of the diaphragm, has been diftinguifhed by the appellation of Paraphrenias, as fuppofed to be attended with the peculiar fymptoms of delirium, rilus fardonicus, and other convulfive motions: but it is certain, that an inflammation of that portion of the pleura, -and affecting '•alfo even the mufcular fubftance ofthe diaphragm, has of- ten taken place without any of thefe fymptoms; and I have not met with either diffedions, or any accounts of di flections, which fupport the opinion, that an inflammation of the pleu- ra covering the diaphragm, is attended with delirium more commonly than any other pneumonic inflammation. or PHYSIC : 141 3 4 4. J With refpea to the feat of pneumonic inflamma- tion, I muft obferve further, that although it may arife and fubfiit chiefly in one part of the pleura onlv. it is however frequently communicated to other, parts ofthe fame, and commonly communicates a morbid affeaion through its whole extent, 345.J The remote caufe of pneumonic inflammation, is commonly cold applied to the. body, obftructing perfpira- tion, and determining to the lungs ; while at the fame time the lungs themfelvcs arc expofed to the aaion of the cold. Thefe circumftances operate efpecially, when an inflamma- tory diathefis prevails i \ the fyftem ; and, confequently, upon perfons of the greater! vigor; in cold climates; in the winter feafon ; and particularly in the fpring, when vicifli- tudes of heat and cold are frequent. The difeafe, however, may arife in any feafon when fuch viciflitudes occur. Oihcr remote caufes alfo may have a fhare in this mat- ter ; fuch as every means of obllruaing, {training,* or o- therwife injuring,t the pneumonic organs. Pneumonic inflammation may happen to perfons of any age. but rarely to thofe under the age of puberty: and moll commonly it affeas perfons fomewhat advanced in life, as thofe between forty-five and fixty years ; thofe two, efpe- cially of a robuft aiid full habit. The pneumonic inflammation has been fometimes £0 much an epidemic, as to occafion a fufpicion of its depend- ing upon a {'pacific contagion ; but I have not met with any evidence in proof of this.—See Morgagni de can sis et sedibus morborum, epift. xxi. art. 26. 346. J The pneumonic, like other inflammations, may terminate by refolution, fuppuration, or gangrene; but it has alfo a termination peculiar to itfelf, as has been hinted above (259J ; a:id that is, when it is attended with an effu- fion of blood into the cellular texture of the lungs, which foon interrupting the circulation of the blood through this vifeus, produced a fatal fu [location. This, indeed, feems * Violent excraons, in fpeaking, finging, playing on wind inftruments, ruu- ni'i',- up hill, or in fliort any exercifs that iuci-eafes the action of the lungs. f Receiving nnxious vapors into the lungs is fometimes the caufe ot pneu- monic inflammation ; efpecially coiTiiive qp other acrid poifonous vapors, as the fumes of ari'enic, of fulphur, ofthe muriatic acid, and iimilar cauilic and definitive exhalations.

The fame exudation fhows itfelf, alfo, by a quantity of a ferous whitifh fluid, commonly found i:r the cavity ofthe thorax; and fome exudation or effufion is ufuallv found to have been made likewife into the cavity of the pericar- dium. 348.] It feems probable, too, that a like effufion is fome- times made into the cavity of the bronchiae : for, in fome perfons who have died after labouring under a pneumonic inflammation for a few days only, the bronchiae have been found filled with a confiderable quantity of a ferous and thickifh fluid; which, I think, muft be confidered rather as the effufion mentioned, having had its thinner parts tak- en off by refpiration, than as a pus fo fuddenly formed in the inflamed part. 349.] It is, however, not improbable, that this effufion, as well as that made into the cavities ofthe thorax and pe- ricardium, may be a matter of the lame kind with that which, in other inflammations is poured into the cellular texture of the parts inflamed, and there converted into pus : but, in the thorax and pericardium, it does not always af- fume that appearance, becaufe the cruft covering the fur- face prevents the abforption of the the thinner part. This abforption, however, may be compenfated in the bronchiae by the drying power of the air ; and therefore the effufion into them may put on a more perulent appearance. In many cafes of pneumonic inllammation, when the Sputa are very copious, it is difficult to fuppofe that the whole of them proceed from the mucus follicles ofthe bron- chiae. It feems more probable that a great part of them OF PHYSI C. US may proceed from the effufed ferous fluid we have been mentioning ; and this too will account for*thc fputa beiiig fo often of a pcrulent appearance. Perhaps the fame thing may account for that pcrulent expeaoration^ as well as that pcrulent matter found in the bronchiae, which the learn- ed Mr. de Hacn fays he had often obferved, when there was no ulceration ofthe lungs: and this explanation is at leaft more probable than Mr. de Haen's fuppofition of a pus formed in the circulating blood. 350.] To conclude this fubjett, it would appear, that the effufion into the bronchiae which we have mentioned, often occurs with the effufion of red blood in occafiomeg the fuffocation, which fatally terminates pneumonic inflam- mation ; that the effufion of ferum alone may have this ef- fea; and that the ferum poured out in a certain quantity, rather than any debility in the powers of ?xpecloration, is the caufe of that ceafing of expeaoration which very con- flantiy pre^edej the fatal event. For, in many cafes, the expectoration has ceafed, when no other fymptoms of de- bility have appeared, and when upon diffenion, the bron- chiae have been found full of liquid matter. Nay, it is even probable, that in fome cafes, fuch an effufion may take place, without any fymptoms of violent inflamma- tion ; and in other cafes, the effufion taking place, may feem to remove the fymptoms of inflammation which had appeared before, and thus account for thofe unexpeaed fatal terminations which have fometimes happened. Poffi- bly this effufion may account alfo for many of the pheno- mena of the Peripneumonia Notha. 351.] Pneumonic inflammation feldom terminates by refolution, without being attended with fome evident eva- cuation. An haemorrhagy from the nbfe happening upon fome of the firft days ofthe difeafe, has fometimes put an end to it; and it is faid that an evacuation from the hemor- rhoidal veins, a bilious evacuation by ftool, and an evacu- ation of urine with a copious fediment, have feverally had the fame effea : but fuch occurrences have been rare and unufual. The evacuation moft frequently attending, and feeming to have the greateft effett in promoting refolution, is an expeaoration of a thick, white, oryellowifh matter, a little H4r P R A C 1 l t: L ftreaked with blood, copious, and brought up without either much or violent couohin?". Very frequently the refolution of this difeafe is attended with, and perhaps produced by a fweat, which is warm, fluid, copious over the whole body, and attended with an abatement of the frequency of the pulfe, ofthe heat ofthe body, and ofthe other febrile fympioms. 352.] The prognostics in this difeafe are formed from obferving the ftate of the principal fymptoms. A violent pyrexia is always dangerous. The danger, however, is chiefly denoted by the difficul- ty of breathing. When the patient can lie on one fide on- ly ; when he can lie on neither fide, but upon his back on- ly ; when he cannot breathe with tolerable cafe, except the trunk of his body be ereCt; when even in this pofture the breathing is very difficult, and attended with a turgef- cence and flufhing of the face, together with partial fweats about the head and neck, and an irregular pulfe : thefe circumftances mark the difficulty of breathing in progreff- ive degrees, and confequently, in proportion, the danger ofthe difeafe. A frequent violent cough aggravating the pain, is always the fymptom of an obftinate difeafe. As I apprehend that the difeafe is hardly ever rcfolvcd, without fome expeaoration ; fo a dry cough muft be al- ways an unfavorable fymptom. As the expectoration formerly defcribed, marks that the difeafe is proceeding to a refolution ; fo an expectoration which has not the conditions there mentioned, muft denote at leaft a doubtful ftate of the difeafe ; but the marks taken from the colour ofthe matter are for the moft part falla- cious. An acute pain, very much interrupting infpiration is al- ways the mark of a violent difeafe; though not of one more dangerous, than an obtufe pain, attended with very diffi- cult refpiration. When the pains, which at firft had affeaed one fide only, have afterwards fpread into the other ; or when leaving the fide firft affeaed, they entirely pafs into the other : thefe are always marks of an increafing, and therefore of a dan- gerous difeafe. Or: P H Y SIC. US A deliiium coming on during a pneumonic inflammati- on, is conftantly a fymptom denoting much danger. 353-J When the termination of this difeafe proves fatal, it is on one or other of the days ofthe firft week, from the third to the fevcnth. This is the moft common cafe ; but, i:i a few inftanccs, death has happened at a later period of the difeafe. When the difeafe is violent, but admitting of refolution, this alfo happens frequently in the courfe of the firft week; but, in a more moderate ftate ofthe difeafe, the refolution is often delayed to the fecond week. The difeafe, on fome of the days from the third to the feventh, generally fuffers a remiffion ; which, however, may be often fallacious, as the difeafe does fometimes re- turn again with as much violence as before, and then with great danger. Sometimes the difeafe difappears on the fecond or third day, while an.eryfipelas makes its appearance on fome ex- ternal part : and if this continue fixed, the pneumonic in- flammation does not recur. 354-J Pneumonia, like other inflammations, often ends in fuppuration or gangrene.* 355. J When a pneumonia, with fymptoms neither very violent nor very flight, have continued for many days, it is to be feared it will end in a fuppuration. This, however, is not to be determined precifcly by the number of days: for, not only after the fourth, but even after the tenth day, * As this termination of Pneumonia is always fatal, it is highly" neceffary that the phyfician (hould be able to knew when a gangrene is to be fufpeaed, that lie may take the proper means for preventing it: or, when it is abfolute* ly formed, that he may favc his reputation, by informing the patient's relati- ons of the impending danger, and the fatal confcquences with which fuch a termination is attended : I fhall therefore add fome of the moft remarkable diagnoftics of an incipient gangrene in this difeafe. A purulent fpitting, ftreakedwith deep colored blood, or wiA a blackiih matter; a fetid breath ; a rattling in the throat; a dejected conwenance ; a dim eye ; a languid quick pulfe ; the blood drawn from a vein void of the inflammatory cruft; fetid green ftools in abundance ; urine of a bright flame color, or depofiting a black fediment of a fcaly appearance. More fymptoms of this fatal termination are unneceffary ; for, if moft of the above mentioned be prefent, the phyfician has no other duty to perform than warn the friends of the patient that death may Ije foon expected. It may be farther remarked, that when a gangrene is begun, the patient is confiderably freed from pain, and both himfelf and his attendants have great hopes of his recovering ; a few hours, however, foon undecieves them, and raifes the reputation of the phyfician, who has pro- nounced, a true prognofis. See fome other diagnoftics of gangrene $1 the notes on article 359. Vol. I. T 146 T R A C T I C £ there have been examples of a pneumonia ending by a re- folution ; and if the difeafe has fuffered fome intermiffion and again recurred, there may be in fiances of a refolution happening at a much later period from the beginning of the difeafe, than that juft now mentioned. 356.] But if a moderate difeafe, in fpite of proper re- medics employed, be protraaed to the fourteenth day with- out any confiderable remiflion, a fuppuration is pretty cer- tainly to be expcaed ; and it will be ftill more certain, if no figns of refolution have appeared, or if an expectorati- on which had appeared fhall have again ceafed, and the dif- ficulty of breathing has continued or increafed, \\ bile the other fymptoms have rather abated. 357.J That in a pneumonia, the effufion is made, which may lay the foundation of a fuppuration, we conclude from the difficulty of breathing becoming greater when the patient is in a horizontal pofture,* or when he can lie more eafily upon the affeaed fide. 358.J That in fuch cafes, a fuppuration has aft-uaHy be- gun, may be concluded from the patient's be in 3 frequently affeaed with flight cold fhiveiings, and v. ith a fenfe of cold fometimes in one, and fometimes in another part of the body. We form the fame conclufion alfo from the Rate of the pulfe, which is commonly lefs frequent and lbftcr, but fometimes quicker and fuller than before. 359.] That a fuppuration is already formed, mav he inferred from there being a confiderable remiflion r of the , pain which had before fubfifted, while along with this, 1 the cough, and efpecially the dyfpnoca, continue, and arc rather augmented. At the fame time, the frequency of the pulfe is rather increafed ; J the feverifh ftate fuffers consi- derable exacerbations every evening, and bv degrees, a heaic in all its circumftancfKs comes to be formed. * In all pneumonic affections, the breathing is generally mere difficult when the patient lies in an horizontal pofture, it cannot therefore be admitted as ^ diagnoitic of an effufion. f The young phyfician muft be on his guaid with refptft to this fymptom:- I for it is alfo a fvmptcm of an incipient, or an already formed gangrene: he ought therefore to be peculiarly attentive to the concomitant Iymptoms v. hie a j the author enumerates, viz. the continuance or augmentation oT the d'nT.cul'y J of breathing and the cough, both of which cither totally difr.ppcar, crate m confiderably leffened on the fupervention of gangrene. ™ \ The-increafed frequency cf the pulfe is alfo a fymptcra cf a rar.frene be- ii'ii formed, but if that increafed frequency he attended with febrile esae'erba- of physic. nr 300.] The termination of Pneumonia by gangrene, is much more rare than has been, imagined ; and when it does occur, it is ufually joined with the termination by effufion (346.) and the fymptoms ofthe one arc hardly to be dif- tinguilhed from thofe of the o.her. 361.] The cure of pneumonic inflammation, muft pro- ceed upon the general plan (264.) but the importance of the part affeaed, and the danger to which it is expofed, re- quire that the remedies be fully, as well as early employed. 362.] The remedy chiefly to he depended upon, is that of bleeding at the arm ; which will be performed with mo ft advantage in the arm of the fide moft affeaed, but mav be done in either arm, as may be moft convenient for the pa- tient or the furgeon. The quantity drawn muft be fuited to the violence of the difeafe, and to the vigour of the pa- tient ; and generally ought tobe as large as this laft circum- ftance will allow. The rcmiffion of pain, and the relief of refpiration, during the flowing ofthe blood, may limit the quantity to be then c|rawn ; but if thefe fymptoms of relief do not appear, the bleeding fhould be continued till the fymptoms of a beginning fyncope come on. It is feldom that one bleeding however large, will prove a cure of this difeafe; and although the pain and difficulty of breathing may be much relieved by the firft bleeding, thefe fjmp- toms commonly, and after no long interval, recur, often with as much violence as before. In the event o^fuch re- " currence the bleeding is to be repeated, even in the 'courfe of the fame day, and perhaps to the fame quantity as before. Sometimes the fecond bleeding may be larger than the firft. There are pei fens who, by their conftitution, are ready to fei it even upon a fmall bleeding; and in fuch perfons this may prevent the drawing fo much blood at firft as a pneumonic inflammation might require ; but, as the fame perfons are frequently found to bear after-bfeed- ings better than the firft, this allows the fecond and fubfe- cjucnt bleedings to be laigeiv and to fuch a quantity as the fymptoms ofthe difeafe may feern to demand. 363. J It is according to the ftate ofthe fymptoms, that tions ift the evenings, then, and then-only can tho. phyfician be fure that th« dilcafs '..as •.ermiuaii.i in fuppuration, and .:i£ in cftngrenc. 148 PRACTICE bleedings are to be repeated; and they will be more effec- tual when praaifed in the courfe of the firft three days, than afterwards; but they are not to be omitted, although four days may have already clapfed. If the phyfician fhall not have been called in fooner; or if the bleedings praaifed during the firft days fhall not have been large enough, or even although thefe bleedings fhall have procured fome re- miflion ; yet upon the recurrence of the urgent fymptoms, the bleeding fhould be repeated at any period of the dii- cafe, efpecially within the firft fortnight ; and even after- wards, if a tendency to fuppuration be not evident, or if, after a feeming folution, the difeafe fhall have again returned. 364. J With refpea to the quantity of b'lood which ought, or which with fafety may be taken away, no general rules can be delivered, as it muft be very different, according to the ftate of the difeafe and conftitution of the patient. In an adult male of tolerable ftrength, a pound of blood, avoirdupois, is a full bleeding. Any quantity abo ve twen- ty ounces, is a large, and any quantity below twelve a fmall bleeding. A quantity of from four to five pounds, in the courfe of two or three days, is generally as much as fuch patients will fafely bear; but, if the intervals between the bleedings and the whole of the time during which the bleed- ings have been employed have been long, the quantity taken upon the whole may be greater.* 365. J When a large quantity of blood has been ahcady taken from the arm, and when it is doubtful if more can with fafety be drawn in that manner, fome blood may ftill be taken by cupping and fcarifying. Such a meafure will be more particularly proper, when the continuance or * Bleedings produce the bell effect, when the blood is drawn off as quicl.ly as poffible in a large full ftream : and in order to prevent fyncope, the patient ought to be laid horizontally, or even with his head low* r than his trunk. With refpecl; to the quantity of blood to be drawn at once, or in the whole courfe 6f the difeafe, no general directions can be given : it muft depend en- tirely on the circumftances of the difeafe and the patient. In general, it is ufual to continue the difcharge until the patient can either breathe more freely, or feels a confiderable abatement of the pain. If, however, th? pain does not abate while the blood continues to flow, but figns of fainting appear, the blood muft then be-immediately {topped. If the pain and other fymptoms continue violent, or return after the firft bleeding, it will then be neceffary to have re- courfe to the operation : and it muft be repeated frequently through the courfe nf the difeafe : avoiding, however, fo large an evacuation at once as may in- duce fainting. The reafon of this precaution is evident, viz. that while the motion of the heart is fufp£nded during fainting, the bleed Magnate* in the right fide of the heart, a*d jjpaftenvavds thrown with greuicr impetucfity through the lungs. * *\fcj|^^. it O F P H Y S I C. 149 recurrence of pain, rather than the difficulty of breathing, becomes the urgent fymptom; and then the cupping and fcarifying fhould be made as near to the pained part as can conveniently be done. 366.] An expeaoration takes place fometimes very early in this difeafe; but if, notwithflanding that, the urgent fymptoms fhould ftill continue, the expeaoration muft not fuperfede the bleedings mentioned; and during the firft v days of the difeafe, its folution is not to be trufted to the expeaoration alone. It is in a more advanced ftage only, when the proper remedies have been before employed, and when the fymptoms have fuffered a confiderable remiflion, that the entire cure may be trufted to a copious and free expe6toration. 367.J During the firft days of the difeafe, I have not found that bleeding (tops expeaoration. On the contrary, I have often obferved bleeding promote it; and it is in a more advanced ftage of the difeafe only when the patient, by large evacuation and the continuance of the difeafe, has been already exhaufted, that bleeding feems to flop expec- toration. It appears to me, that even then bleeding does not ftop expeaoration fo much by weakening the powers of expectoration, as by favouring the ferous effufion into the bronchiae, (348) and thereby preventing it. 368. J While the bleedings we have mentioned fhall be employed, it will be neceffary to employ alfo every part of the antiphlogiftic regimen, (130—132) and particularly to prevent the irritation which might arife from any increafe of heat. For this purpofe, it will be proper to keep the patient out of bed, while he can bear it eafily ; and when he cannot, to cover him very lightly while he lies in bed. The temperature of his chamber ought not to exceed fixty degrees of Farenheit's thermometer ; and whether it may be at any time colder, I am uncertain. 369. j Mild and diluent drinks, moderately tepid, at leaft never cold, given by fmall portions at a time, ought to be adminiftered plentifully. Thefe drinks may be impregnated with vegetable acids.* They may be properly accompani- ed alio with nitre, or fome other neutrals;? but thefe falts fhould be given feparately from the drinks.J * See the Note on Art. 131. aci>U. f See the Note on Art. 160.

But as, when the irrita- tion of a blifter is prefent, it renders bleeding lefs effettu- al; fo the application of the blifter fhould be delayed till on is abfelutely neceffary in thefe cafCs, fo far from rendering the patient's common dri.ik naufeous, by impregnating it with ill flavored medicines, wc ooghr by every poffible means, to endeavor to make it as agreeable as we can, that he may be the more eafily prevailed on to take it plentifully. * The cooling laxaiives are, falts, manna, See. but in thefe cafes, 3 or 4 ounces of infufum femise, wiih half aa ounce of Glauber's fait may be given with*«t danger- * f The tartar emet;c is the medicine generally employed for this- purpofe.

If the difeafe Le moderate, the blifter may be applied immediately after the firft bleeding; but if the difeafe be violent, and it is prefum- ed that a fecond bleeding may be neceffary foon after the firft, it will then be proper to delay the firft blifter till alter the fecond bleeding, when it may be fuppofed that any fur- ther bleeding may be poftponed till the irritation arifing from the blifter fhall have ceafed. It may be frequently neceffary in this difeafe to repeat the bliftering: and in that cafe the plaifters fhould always be applied fomewhere on the thorax ; * for, when applied to more diftant parts, they have little effea.

The pilulx lilitierc of the Edinburgh Pharmacopoeia is a good formula, except that the dofe of it muft be large, in order to take a fufficientquantity*!' the fquills, 10 grains of it containing only 1 grain of dry fquills, fuppofing no fyrup to be ufed in making the mafs. One convenience indeed, attends this formula, viz. that we can give fmall dofes with more pre- ciliun than if we ufed the powder alone. The gum ammoniac is an expecto- rant; and therefore, when given along with the fquills in.thefe pills, may render a k-fs dole ofthe fquills neceffary. If the extraft of liquorice be omit* ted, the p. .portion of thefquir* to the whole will be iiKrj;U;d. 152 PRACTICE impregnated with vinegar, has often proved ufeful in pro- moting expeaoration.* But, of all other remedies the moft powerful for this purpofe, are antimonial medicines, given in naufeating do- fes, as in (179). Of thefe, however, I have not found the kermes mineral more efficacious than emetic tartar, or an. limonial wine ; and the dofe ofthe kermes is much more uncertain than that of the others. 374.] Though a fpontaneous fweating often proves the crifis of this difeafe, it ought not to be excited by art, un- lefs with much caution. At leaft I have not yet found it either fo e.ffcaual or fafe, as fome writers have alledged. When, after fome remiffion ofthe fymptoms, fpontaneous fweats of a proper kind arife. they may be encouraged ; but it ought to be without much heat, and without ftimu- lant medicines. If, however, the fweats be partial and clammy only, and a great difficulty of breathing ftill re- main, it will be very dangerous to encourage them. 375. J Phyficians have differed much in opinion with re- gard to the ufe of opiates in pneumonic inflammation. To me it appears, that, in the beginning of the difeafe, and be- fore bleeding and bliftering have produced fome remiffion ofthe pain and of the difficulty of breathing, opiates have a very bad effect, by their increafing the difheuiy of breath- ing, and other inflammatory fymptoms. But in a more advanced ftate ofthe difeafe, when the difheuiy of breath- ing has abated, and when the urgent fymptom is a cough, proving the chief caufe ofthe continuance ofthe pain and of the want of fleep, opiates may be employed with great advantage and fafety. The interruption of the expec- toration, which they feem to occafion, is for a fhort time only; and they feem often to promote it, as they occafion a ftagnation of what was by frepuent coughing diffipated infenfibly, and therefore give the appearance of what phyficians have called Concoaed Matter. * Some praaitioners propofethe fteam of vinegar alone : but it proves in general too irritating. The fame objeftion may be made againft ufing the fteam of wine, which fome praaitioners have recommended inftead of the fteam of vinegar. Plain water is the beft, as the warm vapor only a&s br relaxing the internal furface of the lungs. OF PHiSIC. 153 CHAP. VII. fl)f t&e Peripneumonia jftot&a, oi* 15agta# peripneumony* 376.] XJL DISXASE under this name is mentioned in fome medical writings of the fixtcenth century; but it is very doubtful if the name was then applied to the fame dif- eafe to which we now apply it. It appears to me, that unlets fome. of the cafes detcribed under the title of Ca- tarrhus Suffocative be fuppofed'to have been of the kind I am now to treat of, there was no defcription of this dif- eafe given before that by Sydenham, under the title I have employed here. 37-7.] After Sydenham, Boerhaave was the firft who in a fyftem took notice of it as a diftina difeafe; and he has defcribed it in his aphorifms, although with fome circum- ftances different from thofe in the defcription of Sydenham. Of late, Mr. Lieutaud has with great confidence afferted, that Sydenham and Boerhaave had, under the fame title, defer.!bed different difeafes ; and that, perhaps, neither of them had on this fubjea delivered any thing but hypothefis. 378.] Notwithflanding this bold affertion, I am humbly of opinion, and the Baron Van Swieten feems to have been of the fame, that Sydenham and Boerhaave did defcribe under the fame title, one and the fame difeafe. Nay, I am further of opinion, that the difeafe defcribed by Mr. Lieutaud himfelf, is not effcntially different from that def- cribed by both the other authors. Nor will the doubts of the very learned, but modeft Morgagni, on this fubjea, difturb us, if we confider, that while very few defcribers of difeafes either have it in their power,' or have been fufticiently attentive in diftinguifhing between the effential a;id accidental fymptoms of difeafe; fo, in a difeafe which may have not only different, but a greater number of fymptoms, in one perfon than it has in another, we need not wonder that the defcriptions of the fame difeafe by differ- ent perfons fliould come out in fome refpeas different. I fhall, however, enter no further into this controverfy ; but endeavour to defcribe the difeafe as it has appeared to myr Vol. I. U 1*4 PRACTICE felf; and, as I judge, in the effential fymptoms, much the fame as it has appeared to all the other authors mentioned, 379-] This difeafe appears at the fame feafons that other pneumonic and catarrhal affeaions commonly do ; that is, in autumn and fpring. Like thefe difeafes alfo, it is feem- ingly occafioned by fudden changes of the weather from heat to cold. It appears, alfo, during the prevalence of contagious catarrhs.; and it is frequently under the form ofthe Peripneumonia Notha that thefe catarrhs prove fa- tal to elderly perfons. This difeafe attacks moft commonly perfons fomewhat advanced in life, efpecially thofe of a full phlegmatic habit; thofe who have before been frequently liable to catarrhal affeaions; and thofe who have been much addiaed to the large ufe of fermented and fpiritous liquors. The difeafe commonly comes on with the fame fymp- toms as other febrile difeafes; that is, with alternate chills and heats; and the fymptoms of pyrexia are fometimes fufficiently evident; but in moft cafes thefe are very mode- rate, and in fome hardly at all appear. With the firft attack ofthe difeafe, a cough comes on; ufuafly accompanied with fome expeaoration, and in many cafes, there is a frequent throwing up of a confiderable quantity of vifcid opaque ma- cus. The cough often becomes frequent and violent; is fometimes accompanied with a rending head-ach ; and, as in other cafes of cough, a vomiting is fometimes excited by it. The face is fometimes flufhed, and fome giddinefsor drowfinefs often attends the difeafe. A difficulty of'breath- ing, with a fenfe of oppreffion, or ftraitening in the cheft, with fome obfeure pains there, and a fenfe of laffitude over the whole body, very conftantly attends this difeafe. The fclood drawn in this difeafe, ihows a buffy furface, as in other inflammatory affeaions. The difeafe has often the appearance only of a more vu olent catarrh, and after the employment of fome remedies is entirely relieved by a free and copious expeaoration. In other cafes, however, the feverifh and catarrhal fymp. toms are very moderate, and even flight; but after a feW/j days, thefe fymptoms fuddenly become confiderable, and' put an end to the patient's life when the indications of dan- ger were before very little evident. OF PHYSIC. 155 380.] From the different circumftances in which this dif- eafe appears, the pathology of it is difficult. It is certain- ly often no other at firft than a catarrhal affeaion, which,. in elderly perfons, is frequently attended with a large afflux of mucus to the lungs;. and. it was on this footing that Sydenham confidered it as only differing in degree from his Febris Hyemalis. A catarrh* however, is ftri&ly an affection of the mucus membrane and follicles of the bronchia? alone : but it may readily have, and frequently has, a degree of pneumonic inflammation joined to it; and in that cafe may prove more properly the peculiar dif- eafe we treat of here. But, further,, as pneumonic inflam- mation very often produces an effufion of ferum into the bronchia; (348.) fo this, in elderly perfons, may occur in confequence of a flight degree of inflammation ; and when it does happen, will give the exquifite and fatal cafes ofthe peripneumonia notha. 381.] After this attempt to eftablifh the pathology, the method of cure in the different circumftances of the dif- eafe will not be difficult. In cafe the fever, catarrhal and pneumonic fymptoms, are immediately confiderable, a blood-letting, will certain- ly be proper and neceffary : but, where thefe fymptoms are moderate, a blood-letting will hardly be requisite; and, when an effufion is to be feared, the repetition of blood- letting may prove extremely hurtful*. In all cafes the remedies chiefly to be depended upon, arc vomitingt and bliftering. J Full vomiting may be frequently repeated, and naufea- ting dofes |[ ought to be conftantly employed. * The intention of bleeding in this difeafe is merety to facilitate the circu- lation through the lungs, and to relieve the oppreflion in the breaft, when this intention is therefore anfwtred, and when the fhortnefsof breath and oppref- fion about the breaft are removed, there is no farther need of the lancet. As this difeafe chiefly attacks elderly perfons, and fuch as are of a phlegmatic habit, much harm may be dyne by repeated, bleedings, which alwajs increafe debility and retard the cure. t Vomiting, in this difeafe, has been thought by many praaitioners to be a doubtful remedy. The aftion of vomiting always oppreftes the breaft, and fometimes even increafes the fymptoms ofthe difeafe. t This is the chief remedy : and the blifters ought to be applied as near the part affecled as pofTible. |j In feveral of the former Jfotes we have- fully defcribed the methed of giv- ing the emetic tartar in naufeating doft s. Their principal effect, is to procure a perfpiration: and, when this effect is produced, the patient muft drink largely of any diluent or attenuating liquor, as thin barley water, with ths 15$ PRACTICE Purging may perhaps be ufeful; but as it is feldom fo in pneumonic affeaions, nothing but gentle laxatives are here neceffary.* In all the circumftances of this difeafe, the antiphlogif- tic regimen is proper ; cold is to be guarded againft ; but much external heat is to be as carefully avoided. 382.] If a perfon fweats eafily, and it can be brought out by the ufe of mild tepidliquors only, the praaice may in fuch perfons be tried. See Morgagni de Sed. et Caus. Epift. xiii. Art. 4. 383.] I might here, perhaps give a feparate feaion on the Carditis and Pericarditis, or the inflammation of the 'Heart and Pericardium; but they hardly require a particu- lar confideration. An acute inflammation of the pericardi- um is almoft always a part of the fame pneumonic affec- tion I have been treating of; and is not always diftin- guifhed by any different fymptoms: or, if it be, does not require any different treatment. The fame may be faid of an acute inflammation of the heart itfelf; and when it happens that the one or other is difcovered by the fymp- toms of palpitation or fyncope, no more will be implied than that the remedies of pneumonic inflammation fhould be employed with greater diligence. From diffeaions, which fhew the heart and pericardium affeaed with erofions, ulcerations, and abfeeffes, we difco- ver, that thefe parts had been before affeaed with inflam- mation ; and that in cafes where no fymptoms of pneumo- addition ofthe juice of fome of the acid fruits, or infulions of feme of the gentle aromatics, as fage.Jjalm, mint, &c. or even a thin wine whey. * Purging is furely hurtful in this difeafe, by inducing too great a ftate of debility: the inteftines, however, are tobe emptied in the beginning ofthe difeafe, which is beft done by a purging glyfter, and kept open by the fubfe- quent ufe of gentle laxatives, or by repetitions of mild emollient glyfters. The purging glyfter mav be made as follows : ^ ft. Aq. font. lb. 1. Fol. Senn. ^ss. Coqne leniter, et colaturae acute. ^>al. Cathart. ama. Bi. Mel. 511. M. t". Enema. The fubfequent glyfters ought to confift of nothing more than fimple barleyJ water, or milk and water. The laxatives, if they are ufed, fhould be very1 gentle and mild ; as cream of tartar, whey, manna, tamarinds, &.c. Half ari' ounce of manna diffolved in half a pint of cream of tartar whev, makes an a- greeable opening mixture ; half a tea-cupful of it may be taken three or four times a day, fo as to procure at leaft two or threeftools in the twenty-four hours. O F P H Y S I C. 157 nic inflammation had appeared: it may therefore be alledged that thofe inflammations ofthe heart and pericardium fhould be confidered as difeafes independent of the pneumonic. This indeed is juft : but the hiftory of fuch cafes proves, that thofe inflammations had been of a chronic kind, and hardly difcovering themfelves by any peculiar fymptoms ; or, if attended with fymptoms marking an affection of the heart, thefe were, however, fuch as have been known fre- quently to arife from other caufes than inflammation. There is therefore, upon the whole, no room for our treat- ing particularly of the inflammation of the heart or peri- cardium. CHAP. VIII. 2)f tfjc ®a$trftis, or 31nflammation of tU ^tomacf), 384.] ilMONG the inflammations of the abdominal region, I have given a place in our Nofology to the Perito- nitis; comprehending under that title, not only the inflam- mations affeaing the peritonaeum lining the cavity of the abdomen, but alfo thofe affeaing the extentions of this membrane in the omentum and mefentery. It is not, how- ever, propofed to treat of them here, becaufe it is very dif- ficult to fay by what fymptoms they are always to be known; and farther, becaufe when known, they do not require any remedies befide thofe of inflammation in general. I pro- ceed therefore, to treat of thofe inflammations, which af- feaing vifcera of peculiar funaions; both give occafion to peculiar fymptoms, and require fome peculiarities in the method of cure; and I fhall begin with the inflammation of the ftomach. 385.J The inflammation ofthe ftomach is of two kinds, Phlegmonic, or Erythcmatic* The firft may be feated in what is called the Nervous Coat of the ftomach, or in the peritonaeum inverting it. The fecond is always feated in the villous coat and cellular texture immediately fubjacent. * This is a new term : but whoever confiders what is laid in 274, will I expect., perceive the propriety, and even neccifity, of it. 4 158 PRACTICE 38S.] The phlegmonic inflammation of the ftomach, or what has been commonly treated of under the title of Ga- ftritis, is known by an acute pain in fome part of the region. ofthe ftomach, attended with pyrexia, with frequent vom- iting, efpecially upon occafion of any thing being taken down into the ftomach, and frequently with hickup. The pulfe is commonly fmall and hard; and there is a greater lofs of ftrengthin all the funaions of the body, than in the cafe of almoft any other inflammation. 387.J This inflammation may be produced by various caufes; as, by external contufion ; by acrids of various kinds taken into the ftomach; frequently by very cold drink. taken into it while the body is very warm-; and fometimes by over-diftenfion,from the having taken in a large quantity of food of difficult digeftion. All thefe may be confidered as external caufes;. but the difeafe fometimes arifes alfo from internal caufes not fo well underftood. It may arife from inflammations ofthe neighbouring parts com- municated to the ftomach, and is then to be confidered as asymptomatic affeaion only. It may arife alfo from va- rious acrimonies generated within the body, either in the ftomach itfelf, or in other parts, and poured into the ca- vity ofthe ftomach. Thefe are caufes more direaiy ap- plied to the ftomach; but there are perhaps others origin- ating elfewhere, and affeaing the ftomach only fympathe- tically. Such may be fuppofed to have a£ted in the cafe of putrid fevers and exanthematic pyrexia; in which, up- on diffeaion, it has been difcovered that the ftomach had been affeaed with inflammation. 388.J From the fenfibility of the ftomach, and its com- munication with the reft of the fyftem, it will be obvious, that the inflammation of this organ, by whatever caufes produced, may be attended with fatal confequences. In particular, by the great debility which fuch an inflammati- ^ on fuddenly produces, it may quickly prove fatal, without i running the common courfe of inflammations. ■ When it lafts long enough to follow the ordinary courfe •; of other inflammations, it may terminate by refolution, gangrene, or fuppuration. The feirrhofities which are of- ten difcovered affeaing the ftomach, are feldom known to be the confequences of inflammation. OF PHYSIC. 159 389.] The tendency of this difeafe to admit of refolu- tion, may be known by its having arifen from no violent caufe; by the moderate ftate of the fymptoms; and by a gradual rcmiffion of thefe, efpecially in confequence of re- medies employed in the courfe of the firft, or at fartheft, the fecond week of the difeafe. 390.J The tendency to fuppuration may be known by the fymptoms continuing, in a moderate degree, for more than one,or two weeks; and likewife by a confiderable re- miffion of the pain, while a fenfe of weight and an anxiety ftill remain. When an abfcefs has been formed, the frequency of the pulfe is at firft abated; but foon after, it is again increafed, with frequent cold fhiverings, and with marked exacerba- tions in the afternoon and evening, followed by night fweat- ings, and other fymptoms of hectic fever. Thefe at length prove fatal, unlefs the abfcefs opened into the cavity of the ftomach, the pus be evacuated by vomiting, and the ulcer foon heal. 391. J The tendency to gangrene may be fufpeaed from the violence of the fymptoms not yielding to the remedies employed during the firft days of the difeafe : and that a gangrene has already begun, may be known from the hid- den remiffion ofthe pain, while the frequency ofthe pulfe continues, and at the fame time becomes weaker, accom- panied with other marks* of an increafing debility in the whole fyftem. 39fc.] From the diffeaion of dead bodies it appears, that the ftomach very often has been affeaed with inflam- mation, when the charaaeriftic fymptoms of it (386.) had not appeared ; and therefore it is very difficult to lay down any general rules for the cure of this difeafe. 393.] It is only in the cafe of phlegmonic inflammati- on, charaaerifed in (386.) that we can advife the cure or refolution to be attempted by large and repeated bleedings employed early in the difeafe : and we are not to be deter- cd from thefe by the fmallnefs ofthe pulfe; for after bleed- ing, it commonly becomes fuller and fofter. After bleed- ing, a blifter ought to be applied to the region of the fto- * A delirium js one of the moft general concomitants of the increafing dc« bility of tfce fyftem, aud may be confidered as % diagnoftic. 160 PRACTICE mach ; and the cure will be afiiftcd by fomentations ofthe whole abdomen, as well as by frequent emollient and lax- ative glyfters. 394.] In this difeafe, the irritability ofthe ftomach will not admit of any medicines being thrown into it; and if any internal medicines can be fuppofed ncceffary, they muft be exhibited in glyfters. The giving of drink may be tried; but it ought to be of the very mildeft kind, and in very fmall quantities at a time.* 395.] Opiates, in whatever manner exhibited, are very hurtful during the firft days of the difeafe; but when its violence fhall have abated, and when the violenee of the pain and vomiting recur at intervals only, opiates given in glyfters may be cautioufly tried, and fometimes have been employed with advantage. 396.] A tendency to fuppuration, in this difeafe, is to be obviated by the means juft now propofed. After a certain duration of the difeafe, it cannot be prevented by any means whatever; and when actually begun muft jje left to nature; die bufinefs of the phyfician being only to avoid all irritation. 397. J A tendency to gangrene can be obviated in no other way than by the means fuggefted (393.) employed early in the difeafe; and, when it does aaually fupervene, admits of no remedy. 398.] Erythematic inflammations of the ftomach, are more frequent than thofe of thephlemonic kind. It appears at leaft, from diffeaions, that the ftomach has often been affeaed with inflammation, when neither pain nor pyrexia had before given any notice of it; and fuch inflammation I apprehend to have been chiefly of the erythematic kind. ThisTpecies of inflammation alfo, is efpecially to be ex- peaed from acrimony of any kind thrown into the ftomach; and would certainly occur more frequently from fuch a caufe, were not the interior furface of this organ common- ly defended by mucus exuding in large quantities from the numerous follicles placed immediately under the villous * Chicken broth is extremely mild ; it may be taken in fmall quantities, with about 8 or 10 grains of nitre in every pint of it. Lintfeed tea is alfo a very mild drink; and if the inflammation be owing to the prefence of any acrid matter initating the ftomach, it is of great fervice by its fheathing quality OF PHYSIC. 161 coat. Upon many occafions, hov/ever, the exudation of mucus is prevented, or the liquid poured out is of a lefs vifcid kind, fo as to be lefs fitted to defend the fubjacent nerves; and it is in fuch cafes that matters even of mode- rate acrimony, may produce an erythematic affeaion of the ftomach. 399.] From what has been faid, it muft appear that an erythematic inflammation ofthe ftomach may frequently occur; but will not always difcover itfelf, as it fometimes takes places without pyrexia, pain, or vomiting. 400. J There are cafes, however, in which it may be dif- covered. The affeaion ofthe ftomach fometimes fpreads into the oefophagus, and appears in the pharynx, as well as on the whole internal furface of the mouth. When, therefore, an erythematic inflammation affe&s the mouth and fauces, and when at the fame time there fhall be in the ftomach an unufual fenfibility to all acrids, with a frequent vomiting, there can be little doubt of the ftomach being affeaed with the fame inflammation that has appeared in the fauces. Even when no inflammation appears in the fauces yet it if fome degree of pain be felt in the ftomach, if there be a want of appetite, an anxiety, frequent vom- iting, an unufual fenfibility with refpea to acrids, fome thirft, and frequency of pulfe, there will then be room to fufpea an erythematic inflammation of the ftomach; and we have known fuch fymptoms, after fome time, difcover their caufe more clearly by the appearance of the in- flammation in the fauces or mouth. Erythematic in- flammation is often difpofed to fpread from one place to another on the fame furface; and, in doing fo, to leave the place it had firft occupied. Thus, fuch an inflammation has been known to fpread fucceffively along the whole courfe of the alimentary canal, occafioning in the in- teftines diarrhoea, and in the ftomach vomitings; thediarr- hcea ceafing when the vomitings came on, or the vomit- ings upon the coming on of the diarrhoea. 401.] When an erythematic inflammation of the fto- mach fhall be difcovered, it is to be treated differently, ac- cording to the difference of its caufes and fymptoms. When it is owing to acrid matters taken in by the mouth, and when thefe may be fuppofed ftill prefent in the ftomach, Vol. I. X Ifi PRACTICE they are to be wafhed out by throwing in a large quantity of warm and mild liquids, and by exciting vomiting. At the fame time, if the nature ofthe acrimony and its proper correaor be known, this fhould be thrown in ; or if a fpe- cific correaor be not known, fome general demulcents fhould be employed. 402. J Thefe meafures, however, arc more fuited to pre- vent the inflammation, than to cure it after it has taken place. When this laft may be fuppofed to be the cafe, if it be attended with a fenfe of heat, with pain and pyrexia, according to the degree of thefe fymptoms the meafures propofed in (393.) are to be more or lefs employed. 403.] When an erythematic. inflammation of theftomach has arifen from internal caufes, if pain and pyrexia accom- pany the difeafe, fome bleeding, in perfons not otherwife weakened, may be employed: but, as the affeaion often arifes in putrid difeafes, and in convalefcents from fever^ fo in thefe cafes, bleeding is inadmiffible ; all that can be done being to avoid irritation, and to throw into the fto- mach what quantity of acids, and ofafecfeent aliments, it fhall be found to bear. In fome conditions ofthe body in which this difeafe ari- fes, the Peruvian bark and bitters may feem to be indica- ted ; but an erythematic ftate of the ftomach does not com- monly allow of them. CHAP. IX. SDf t&e <£nte?itte, or 3|nflammation of tfee 3[ntcstine^ 404.] 1 HE inflammation of the inteftines, like that of theftomach, may be either phlegmonic or erythematic; but, on the fubjeft of the latter, I have nothing to add to what has been faid in the laft chapter; and fhall here there- fore treat ofthe phlegmonic inflammation only. 405.] This inflammation may be known to be prefent, by a fixed pain in the abdomen, attended with pyrexia, cof- tivenefs, and vomiting. Praaical writers mention the pain in this cafe as felt in different parts of the abdomen, accord- ing to the different feat ofthe inflammation3 and fo, indeed, OF PHYSIC. 163 it-irtfbmctirncs happens; but very often the pain fpreaas over the whole belly, and is felt more efpecially about the navel. 406.] The Enteritis and Gaftritis arife from like caufes; but the former more readily than the latter, proceeds from cold applied to the lower extremities, or to the belly itfelf. The enteritis has likewife its own peculiar caufes, as fuper- vening upon the fpafmodic cholic, incarcerated hernia, and, volvulus. 407.] Inflammations ofthe inteftines have the fame ter- minations as thofe ofthe ftomach ; and, in both cafes, the fevcral tendencies are to be difcovered by the fame fymp- toms (389. 391.). 408. j The cure of the interitis is, in general, the fame with that of the gaftritis ; (393. and fcq.) but in the inte- rnes, there is commonly ♦more accefs to the introduaion of liquids, of acids, acefcent, and other cooling remedies, and even of laxatives.* As, however, a vomiting fo fre- quently attends this difeafe, care muft be taken not to ex- cite that vomiting by either the quantity or the quality, of any thing thrown into the ftomach. * I 1 this difeafv,', we ought to be extremely cautious in the adminiftration either of the medicines or diluents. The reafon is evident from the follow- ing confiderations. In every cafe of inflammation of a canal, the bore of that canal is diminilhed, and frequently quite fhut. A quantity of any kind of in- gefta being forced againft this obilrucYion, muft neceflarily increafe the irrita- tion, and coiifrequently aggravate all the fymptoms. The fame reafon may be given for the caution neceffary in prefcribing laxatives, which always ir- ritate ; f r their action generally depends upon the irritation they produce. Large bleedings, emcllient glyfters frequently repeated, fomentations, the v/arm bath, and fmall anodyne glyfters occan\;nally injected, are the moft ef- fectual remedies in the firft ftage of this violent difeafe. When the pain re- mits, and the violence of the fymptoms abates, n ild diluents may then be ad- mitted, as chicken-broth, thin lintfecd tea, 8cc. and if fuch liquors be retain- ed without aggravating the fymptom";, \vu may then venture to give an ounce- of manna every three or four hours, till it procures a paffage. The internal ufe of opium has been extolled by feveral practitioners in.,thcfe cafes; but experience {hews that it generally does harm in every cafe cf in- flammation, efpecially in the early ftages of it. The anodyne glyfter is the lafeft method of ufing opium ; but glyfter3 of this kind are faid to obllruct: This objection is, however, ill founded ; for. by diminifhing the irritation, they evidently tend to refolve the inflammation. The following formula of an anodyne glyfter is generally ufed :„ JRc. Decoct, hord. 5-ir. . Opii puri gr. iv. M. In thefe glyRers, particular care muft be taken to avoid every thing that has the lealt tendency to irritae. If a gangrene be formed before the phyfician. be c;;l'cd, as is too frequently the ca,ic, then all remedies are in vain. 164 PRACTICE The fame obfervation with refpea to the ufe of opiat'es is to be made here as in the cafe of gaftritis. 409.] Under the title of Enteritis, it has been ufual with praaical writers to treat ofthe remedies proper for the cho- lic* and its higher degree named Ileus : but, although it be true that the ententes and cholic do frequently accom- pany each other, I ftill hold them to be diftintt difeafes, to be often occurring feparately, and accordingly to require and admit of different remedies. I fhall therefore delay fpcaking ofthe remedies proper for the cholic, till I fhall come to treat of this difeafe in its proper place. 410.] What might be mentioned with refpea to the fup- puration or gangrene occurring in the enteritis, may be fuf- ficiently underftood from what has been faid on the fame fubjea with refpea to the gaftritis. CHAP. X. £Df ifte hepatitis, or inflammation cf tfcc Litter* 411.] JL HE inflammation of the liver feems to be of two kinds; the one acute, the other chronic. 412.J The acute is attended with pungent pain; confi- derable pyrexia; a frequent, ftrong, and hard pulfe; and high colored urine. 413.] The chronic hepatitis very often does not exhibit any of thefe fymptoms; and it is only difcovered to have happened, by our finding in the liver, upon diffeaion, large abffceffes, which are prefumed to be the effea of fome decree of previous inflammation. As this chronic inflam- mation is feldom to be certainly known, and therefore "does not lead to any determined pra6tice, we omit treating of ifhere, and fhall only treat of what relates to the acute fpecies of the hepatitis.t 414. J The acute hepatitis maybe known by a pain more or lefs acute in the right hypochondrium, increafed by preffihg upon the part. The pain is very often in fuch a part of the fide as to make it appear like that of a pleurify; and frequently, like that too, is increafed on refpiraiioc, * See art. 435. t It is doubtful whether this chronic hepatitis ever exifts. 0 1' PHYSIC. 16S The difeafe is, in fome inftances, alfo attended with a cougb which is commonly dry, but fometimes humid : and whea the pain thus refembles that of a pleurify, the patient can- not lie eafily except upon the fide affeaed. In every kind of acute hepatitis, the pain is often ex- tended to the clavicle, and to the top of the fhoulder. The difeafe is attended fometimes with hickup, and fometimes with vomiting. Many praaical writers have mentioned the jaundice, or a yellow color of the fkin and eyes, as a very conftant fymptom of the hepatitis; but experience has fhown, that it may often occur without any fuch fymp- tom.* 415.] The remote caufes of hepatitis are not always to be dilcerned, and many have been amgned on a very un- certain foundation. The following feem to be frequently evident. 1. External violence from contufions orfalls,and efpecially thofe which have occafioned a fraaute of the cranium. 2. Certain paffions of the mind. 3. Violent fummerheats. 4. Violent exercife. 5. Intermittent and remittent fevers. 6. Cold applied externally, and internal- ly ; and therefore in many cafes the fame caufes which produce pneumonic inflammation, produce hepatitis; and whence alfo the two difeafes are fometimes joined together. 7. Various folid concretions or colfeaions of liquid mat- ter, in the fubftance of the liver, produced by unknown caufes. Laftly, The acute is often induced by a chronic inflammation of this vifcus. 416.] It has been fuppofed, that the hepatitis may^be an affection either of the extremities ofthe hepatic artery, or of thofe ofthe vena potarum; but of the laft fuppofition there is* neither evidence nor probability. 417.] It feems probable, that the acute hepatitis is ah ways an affeaion ofthe external membrane of tire liver _; and that the parenchymatic is of the chronic kind. The acute difeafe may be feated either on the convex or on ths concave furface of the liver. In the former cafe, a more pungent pain and hickup may be produced, and the ref- piration is more confiderably affeaed. In the latter, the e occurs lefs pain; and a vomitting is produced, commonly * This fymptom generally appears, however, after tl* difeafe has continu- ed for three or four days ; perhaps, indeed, it might have been prefent in the beginning, for it is fre<}nemlv fo flight as to cfcape obfervatioJl. 166 PRACTICE by fome inflammation communicated to the ftomach. The inflammation of the concave furface of the liver, may be- readily communicated to the gall bladder and biliary duas;, and this perhaps is the only cafe of idiopathic hepatitis at- tended with jaundice. 418.] The hepatitis, like other inflammation:, may end by refolution, fuppuration, or gangrene; and the tenden- cy to the one or the other of thefe events, may be known from what has been delivered above. 419.] The refolution of hepatitis is often the confe- quence of, or is attended with, evacuations of different kinds. A hemorrhagy, fometimes from the * right nofh il,. and fometimes frorruhe hemorrhoidal veffels, gives a fo- lution of the difeafe. Sometimes a bilious diarrhoea con- tributes to the fame event; and the refolution ofthe hepa- titis, as of other inflammations, is attended with fweating, and with an evacuation of urine, depofiting a copious fe- diment. Can this difeafe be refolved by expeaoration r" It would feem to be fometimes cared by an eryfipelas ap- pearing in fome external part. 420. J When this difeafe has ended in fuppuration, the puscolfeaed may be difcharged by the biliary duels; or, if the Tuppurated part docs not any where adhere clofely to the neighbouring parts, the pus may be difcharged into the cavity of the abdomen; but if, during the firft ftate of inflammation, the affeaed part of the liver fhall have formed a clofe adhefion to fome of the neighboring parts,. the difcharge of the pus after fuppuration may be various, according to the different feat of the abfcefs. When feat- ed on the convex part of the liver, if the adhefion be to the peritonaeum lining the common teguments, the pus. may make its way through thefe, and be difcharged out- wardly ; or, if the adhefion fhould have been to the dia- phram, the pus may penetrate through this, and into the cavity of the thorax, or of the lungs; and through the latter may be difcharged by coughing. When the abfcefs of the liver is feated on its concave part, then, in confe- quence'of adhefions, the pus may be difcharged into the * And the left alfo. It was a fancy of Galen's that inflammatory fevefs were only refolved by fuch hemorrhagies as flowed from the fide affected : Thus, an hemorrhage from the right noftril, refolved an inflammatorv of the liver ; but a difcharge from the left, an inflammavion of the fpleca. OF PHYSIC* 167 ftomach or the inteftines; and into thefe laft, either di- re6tly, or by the intervention of the biliary duels. 421. J The prognoftics h\ this difeafe are. eftablifhed up- on the general principles relating to inflammation, upon the particular circumftances of the liver, and upon the parti- cular ftate of its inflammation. The cure of this difeafe muft proced upon the general plan ; by bleeding, more or lefs, according to the urgency of pain and pyrexia ; by the application of blifters ; by fo- mentations, ofthe external par t> in the ufual manner, and ofthe internal parts by frequent emollient glyfters; by fre- quently opening the belly by means of gentle laxatives, and by diluent and refrigerant remedies., 4 2 2. J Although, in many cafes the chronic hepatitis does not clearly difcover itfelf; yet upon many occafions, it may perhaps be difcovered, or at leaft fufpeaed, from thofe caufes which might affea the liver (316.) having been applied; from feme fulnefs and fome tenfenefs of weight in the righ t hypochondrium ; from fome fhooting pains at times felt in that region; from fome uneafinefs or pain felt upon preffure in that part; from fome uneafinefs from lying upon the left fide; and laftly, from fome degree of pyrexia, combined with more or fewer of thefe fymptoms. When from feme of thefe circumftances a chronic inflammation is to be fufpeaed, it is to be treated by the fame remedies as in the laft paragraph, employ more or lefs, as the degree ofthe feveral fymptoms fhall more diftinftly indicate. 423.] When from either kind of inflammation a fup- puration of the liver has been formed, and the abfcefs points outwardly, the part muft be opened, the pus e- vacuated, and the ulcer healed according to the ordinary rules for clcanfine and healing fuch abfeeffes and ulcers. 424.] I might here confider the Splenitis, or inflamma- tion ofthe fpleen ; but it does not feem neceffary, becaufe the difeafe very feldom occurs. When it does, it may be readily known by the chapter given in our Nofology; and its various termination, as well as the pra&ice which it requires, may be undeiflood from what has been already faid with refpea to the inflammations of the other abdo- minal vifcera. 168 PRACTICE CHAP. XI. 4bi tfje JScpfeititf, or tfee Jnflammaticn of t&t t fcitmegs* 425.] 1 HIS difeafe, like other internal inflammations, is always attended with pyrexia; and is efpecially known from the region of the kidney being affeaed by pain, com- monly obtufe, fometimes pungent. This pain is not in- creafed by the motion of the trunk of the body, .fo much as a pain of the rheumatic kind affeaing the fame region. The pain ofthe nephritis may be often dif- tinguifhed by its fhooting along the courfe of the ureter; and is frequently attended with a drawing up of the tefticle, and with a numbnefs of the limb on the fide affeaed; al- though, indeed, thefe fymptoms moft commonly accom- pany the inflammation arifing from a calculus in the kid- ney or in the ureter. The nephritis is almoft conftantly attended with frequent vomiting, and alfo with coftive- nefs and cholic pains. Ufually the ftate of the urine is changed; it is moft commonly of a deep red color, is voided frequently, and in fmall quantity at a time. In more violent cafes, the urine is fometimes colorlefs. 426.] The remote caufes of this difeafe may be various; as^"external contufion; violent or long continued riding; {trains of 'the mufcles of the back incumbent on the kid- • neys; various acrids in the courfe of the circulation con- veyed to the kidneys; and perhaps fome other internal c3ufes not yet well known. The moft frequent is that of calculous matter obftru6ting the tubuli uriniferi, or calculi formed in the pelvis of the kidneys, and either flicking there, or fallen into the ureter. 427.] The various event of this difeafe may be under- itood from what has been delivered on the fubjea of other inflammations. 428.] Writers, in treating ofthe cure of nephritis, have commonly at the fame time treated of the cure of the Cal- culus renalis; but, though this may often produce ne- phritis, it is to be confidered as a diltina and feparate dif- eafe ; and what I have to offer as to the mode of treating OF PHYSIC. 16jj it, muft be referved to its proper place. Here I fhall treat only of the cure of the Nephritis Vera or Idiopa- thica. ' 429.] The cure of this proceeds upon the general plan, by bleeding, external fomentation, frequent emollient glyfters, antiphlogiftic purgatives, and the free ufe of mild and demulcent liquids*. The application of blifters is hardly admiffible; or, at leaft, will require great care, to avoid any confiderable abforption of ihe cantharides t 430.J The Cyftitis, or inflammation of the bladder, is * Thefe have all been enumerated in fome of,the preceding notes. f This is a very neceffary caution. Blifters generally affect, the urinary organs and veffels, occafloning much irritation, and confequently increafing the inflammation. As the author is rather fnort in his directions for the cure of this very troubhfome inflammation, it maybe proper to add fome particu- lar direclions for regulating our praftice in thefe cafes. An ulcer in the kidneys is extremely difficult to heal ; we ought therefor* always to attempt the cure of nephritis by refolution. The general remedies for anfwering this intention have been frequently enumerated, efpecially in the notes on art. 130—131.—The particular remedies more peculiarly adapt- ed to this difeafe arc demulcent drinks of the fofteft nature, and fuch as are^ leaft apt to irritate the parts ; as lintfeed-tea, decoclion of marih-mallows, &C. Nitre has been recommended among the general antiphlogiftic reme- dies ; but, in nephritis its ufe is doubtful, on account of its paffing quickly by the kidneys, and irritating them. A difficulty of making water is one of the fymptoms of this difeafe, and fome practitioners recommend heating diuretics. This praftice, however, is « extremely hurtful, and ought to be carefully avoided, becaufe thefe warm medicines, as turpentinesjhalfams, &c. always increafe the irritation, efpeci- ally in the urinary paffages. ^. ■ As the colon preffes immediately on the kidneys, efpecially on the right one, we fliould be careful to keep it empty, which js beft done by glyfters.- .Befide the ufe of glyfters in evacuating the contents flf the colon, they ail aa a fomentation to the inflamed part ; we ought therefore, in thefe cafes, to prefcribe them larger than ufual, and repeat them often. They ought to be extremely emollient, and void of every ingredient that is any way ftimulating. A quart of thin barley-wi.ter or liaifted tea anfwers the purpofe as com- pletely as any ofthe more compound emollient glyfters of the Pharmacopoeias. With refpecl to diet and regimen, we may obferve that lenient nourishment is highly proper; for every thing acrid naturally forces itfelf off by the mine, and consequently increaftse the irritation. A total abftinence from food is by no means advifaBle, becaufe, from abftinence, little urine is fecreted, and the fmaller the quantity fecreted it is generally the more acrid, and confe- quently noxious. The patient ought to be made to fit up as much as poffible. Warm foft beds, which are always improper in all inflammatory difeafes, are peculiarly hurtful in nephritis, if the patient lies on his back ; for in this pofition the kidneys are kept very warm, and are at the fame time prefledby the fuperincumbent weight ofthe abdominal vifcera, all which will contri- bute to increafe the inflammation. Although lying much ia bed be dif.p- proved, the patient ought by no means to be overfatigued with fitting too long. The room fliould be moderately cool, and the bed fpringy, but notfofc. In addition to what was faid above refpecling blifters in this difeafe, it may be neceffary to obferve, that other vificants befides cantharides may be ufed, fuch as muilard poultices, commonly called fuiapifms, a poultice of frelh leaves of the ranuntlus acris, and otlier acrid plants. Vol. I. Y J7U -PRACTICE feldom a primary difeafe ; and therefore is not tobe treat- ed of here. The treatment of it, fo far as neceffary to be explained, may be readily underftood from what has been already delivered. 431.] Of the vifceral inflammations, there remains to be confidered the inflammation of the Uterus; but I omit it here, becaufe the confideration of it cannot be feparated from that of the difeafes of child-bearing women. CHAP. XII. ©f tf)e iRfrcumatimtt, 432.] V|/F this difeafe there are two fpecies, the one na- med the Acute, the other the Chronic rheumatifm. 433.] It is the acute Rheumatifm which efpecially be- longs to this place, a? from ifls caufes, fymptoms, and me- thods of cure, it will appear to be a fpecies of phlegmatic or inflammation. ^ 434.] This difeafe is frequent mcedd", a,nd more uncom- mon in warm climates. It appears moft frequently in au- tumn and fpring, lefs frequently in winter when the cold is confiderable and conftant, and very feld^Vi during the heat jof fummer. It may occur, howevfci, at any feafon, if vi- ciflitudes of heat and cold be for the time frequent. 435.] The a£i|^»rheumatifm generally arifes from the application of cold to the body when any way unufually warm ; or when one part ofthe body is expofed to cold whilft the other parts are kept warm ; or, laftly, when the application of the cold is long continued, as it is when wet or moift clothes are applied to any part of the body. 436.] Thefe caufes may affea perfons of all ages; but the rhpumatifm feldom appears in either very young or el- derly' jierfons, and moft commonly occurs from the age of puberty to that of thirty-five years. 437.] Thefe caufes (435.) may alfo affea perfons of any conftitution -, but they moft commonly affeet thofe of a fanguine temperament. 438.] This difeafe is particularly diftinguifhed by pains affecting the joints, for the moft part the joints alone, but fometimes affeaing alfo the mufcular parts. Very often OF PHYSIC. ttt the pains fhoot alone; the courfe ofthe mufcles, from one joint to another, and are always much increafed by the aaion ofthe mufcles belonging to the joint or joints affeaed. 439.] The larger joints are moft frequently affeaed; fuch as the hip-joint and knees ofthe lower, and the fhoul- ders and elbows ofthe upperextremities. The ankles and wrifts are alfo frequently affeaed ; but the fmaller joints, fuch as thofe ofthe toes or fingers, feldom fuffer. 440.] This difeafe although confined to one part ofthe body only, yet very often affeas many parts of it ; and then it comes on with a cold ftage, which is immediately fucceeded by the other Iymptoms of pyrexia and particu- larly by a frequent, full, and hard pulfe. Sometimes the pyrexia is formed before any pains are perceived; but more commonly pains are felt in particular parts, before any fymptoms of pyrexia appear. 441.] When no pyrexia is prefent, the pain is fometime3 confined to one joint only ; but,-when any confiderable py- rexia is prefent, although the pain may be chiefly in one joint, yet it feldom happens-but that the pains affea feve- ral joints often at the very fame time, but for the moft part ^ fhifting their place, and having abated in onejoint, become , more violent in another. They do not commonly remain long in the fame joint, but frequently fhift from one to a- nother, and fometimes return to joints formerly affeaed ; and in this manner the difeafe often continues., for a long time. 442.] The pyrexia attending this difeafe has an exacer- bation every evening, and is moft confiderable during the night, when the pains alfo become more violent; and it is at the. fame time that the pains fhift their place from one joint to another. The pains feem tobe alfo increafed during the night, by the body being covered more clofely, and kept warmer. 443-] A joint, after having been for forne time affeaed with pain, commonly becomes affeaed alfo with fome rednefs and fwelling, which is painful to the touch. It fel- dom happens, that a fwelling coming on does not alleviate the pain of the joint; but the fwelling does not always take off the pain entirely, nor fecure the joint againft a return of it. 44i] The difeafe is commonly attended with fome * m PRACTICE fweating, which occurs early in the courfe ofthe difeafe ; but it is feldom free or copious, and feldom either relieves the pains or proves critical. 445.] In the courfe of this difeafe the urine is high co- loured, and in the beginning without fediment; but as the difeafe advances, and the pyrexia has more confiderable remiffions, the urine depofits a lateritious fediment. This, however, does not prove entirely critical; for the difeafe often continues long after fuch a fediment has appeared in the urine. 446.] When blood is drawn is this difeafe it always ex- hibits the appearance mentioned 237. 447.] The acute rheumatifm, though it has fo much ofthe nature ofthe other phlegmafia?, differs from all thofe hitherto mentioned, in this, that it is not apt to terminate in fuppuration. This almoft never happens in rheumatifm; but the difeafe fometimes produces eifufions of a tranfpa- rent gelatinous fluid into the fheaths of the tendons. If we may be allowed to fuppofe that fuch eifufions are fre- quent, it muft alfo happen, that the effufed fluid is com- monly reabforbed; for it has feldom happened, and never indeed to my obfervation, that confiderable or permanent tumours have been produced, or fuch as required to be o- pened, and to have the contained fluid evacuated. Such tumours, however, have occurred to others, and the open- ing made in them has produced ulcers difficult to heal. Vide Storck. Ann. Med. II. 448.] With the circumftances mentioned from (438. to 447.) the difeafe often continues for feveral wreeks. It fel- dom, however, proves fatal ; and it rarely happens that the pyrexia continues to be confiderable for more than two or three weeks. While the pyrexia abates in its violence, if the pains of the joints continue, they are lefs violent, more limited in their place, being confined commonly to one or a few joints only, and are lefs ready to change their place. 449.] When the pyrexia attending rheumatifm has en- tirely ceafed; when the fwelling, and particularly the red- nefs ofthe joints, are entirely gone ; but when pains ftill continue to affea certain joints, which remain ftiff, which feel uneafy upon motion, or upon change of weather; the dif- eafe is named the Chronic Rheumatifm? as it very often O F P H Y S I C. 173 continues for a long time. As the chronic is commonly the fequel of the acute rheumatifm, I think it proper to treat of the former alfo in this place. 450.] The limits between the acute and chronic rheuma- tifm are not always exaaiy marked. When the pains are ftill ready to fhift their place ; when they are efpecially fevere in the night-time ; when, at the, fame time, they are attended with fome degree of pyrexia, and with fome fwelling, and efpecially with fome rednefs of the joints; the difeafe is to be confidered as ftill partak- ing the nature of the acute rheumatifm. But when there is no degree of pyrexia remaining; when the pained joints are without rednefs; when they are cold and ftiff; when they cannot eafily be made to fweat; or when while a free and warm fweat is brought out on the reft of the body, it is only clammy and cold on the pained joints ; and when, efpecially the pains of thefe joints are increafed by cold, and relieved by heat applied to them; the cafe is to be confidered as that of a purely chronic rheumatifm. 451.] The chronic rheumatifm may affea different joints; but is efpecially ready to affea thofe joints which are fur- rounded with many mufcles, and thofe of which themufeles are employed in the moft conftant and vigorous exertions. Such is the cafe of the vertebrae of the loins, the affeaion of which is named Lumbago; or that of the hip-joint, when the difeafe is named lfchias, or Sciatica. 452.] Violent ftrains and fpafms occurring on fudden and fomewhat violent exertions, bring on rheumatic af- feaions, which at firft partake ofthe acute, but very foon change into the nature of the chronic rheumatifm. 453. J I have thus delivered the hiftory of rheumatifm; and fuppofe, that, from what has been faid, the remote caufes, the diagnofis, and prognofis of the difeafe, may be underftood. The diftinction of the rheumatic pains from thofe refembling them, which occur in the fyphilis and feurvy, will be obvious, either from the feat of thofe pains, or from the concomitant fymptoms peculiar to thefe difeafes.* The diftinttion of rheumatifm from gout * To diftinguifh the chronic rheumatifm from venereal or fcorbuticpains, is, however, in fome cafes, extremely difficult, tr.J cfien requires the uunuft 174 PRACTICE will be more fully underftood from what is to be delivered in the following chapter. 454.] Withrefpea to the proximate caufe of rheumatifm, there have been various opinions. It has been imputed to a* peculiar acrimony; of which, however, in ordinary cafes, I can find no evidence; and from the confideration ofthe remote caufes, the fymptoms, and cure of the dif- eafe, I think the fuppofition very improbable. The caufe of an Ifchias Nervofa affigned by Cotux- nius, appears to me hypothetical, and is not fupportcd by either the phenomena or method of cure. That, how- ever, a difeafe of a rheumatic nature may be occafioned by an acrid matter applied to the nerves, is evident from the toothach, a rheumatic affeaion generally arifing from a carious tooth. That pains refembling thofe of rheumatifm may arife from dcep-feated fuppurations, we know from fome cafes depending on fuch a caufe, and which, in their fymptoms, refcmble the lumbago or ifchias. I believe, however, that by a proper attention, thefe cafes depending on fup- puration, may be commonly diftinguifhed from the genu- ine cafes of lumbago and ifchias ; and, from what is faid in (447.) I judge it to be at leaft improbable, that a genu- ine lumbago or ifchias does ever end in fuppuration. 455.] The proximate caufe of rheumatifm has been by many fuppofed to be a lentor of the fluids obftruaing the veffels of the part; but the fame confideration as in (241. *5 2, 3, 4, and 5) will apply equally here for rejeaing the fuppofition of a lentor. * 456. J While I cannot, therefore, find either evidence or reafon for fuppofing that the rheumatifm depends upon any change in the ftate of the fluids, I muft conclude, that the proximate caufe of acute rheumatifm, is commonly thg fame with that of other inflammations not depending upon a dirett ftimulus. 457.J In the cafe of rheumatifm, I fuppofe, that the fagacity of the pracliticner. A due attention to the caufes of rheumatifm, recited in the foregoing articles, and a ftriclexamination whether the patient has been fubjefted to thefe caufes, will fometimes determine the difeafe; but it oftign happens, that the fame caufes which produce rheumatifm, alfo exacerbate venereal and foorbutic pains. No general rules can be delivered on this fubject; and the practitioner muft truft to his own fagacity fur direc- tion in this difficult diagnofis. OF PHYSIC. 175 moft common remote caufe of it, that is, cold applied, operates efpecially on the veffels of joints, from thefe be- ing lefs covered by a cellular texture than thofe of the in- termediate parts of the limbs. I fuppofe further, that the application of cold produces a con(tri6tion ofthe extreme veffels on the furface, and at the fame time an increafe of tone or phlogiftic diathefis in the courfe of them, from which arifes an increafed impetus of the blood, and, at the fame time, a refiftance to the * free paffage of it, and confequently inflammation and pain. Further, I fuppofe, that the refiftance formed excites the vis medicatrix to a further increafe of the impetus ofthe blood; and, to fup- port this, a cold ftage arifes, a fpafm is formed, and a pyrexia and phlogiftic diathefis are produced in the whole fyftem. 458.] According to this explanation, the caufe of acute rheumatifm appears to be exactly analogous to that of the inflammations depending on an increafed afflux of blood ■to a part while it is expofed to the aaion of cold. But there feems to be alfo, in the cafe of rheumatifm, a peculiar affection ofthe fibres ofthe mufcles. Thefe fibres feem to be under fome degree of rigidity, and therefore lefs eafily admit of motion; and are pained upon the exertions of it. It is alfo an affeaion of thefe fibres which gives an op- portunity to the propagation of pajns from one joint to another, along the courfe of the mufcles, and which pains are more feverely felt in the extremities of the mufcles ter- minating in the joints, becaufe, beyond thefe, the ofcil- lations are not propagated. This affection of the mufcular fibres attending rheu- matifm, feems to explain why ftrains and fpafms produce rheumatic affections; and, upon the whole, fhows, that, with an inflammatory affeaion of the fanguiferous fyftem, there is alfo in rheumatifm a peculiar affection of the muf- cular fibres, which has a confiderable fhare in producing the phenomena of the difeafe. 4 59-J Having thus given my opinion ofthe proximate caufe of rheumatifm, I proceed to treat ofthe cure. 460. J Whatever difficulty may occur with refpea to die explanation given, (457. and 458.) this remains certain; If 6 PRACTICE that in acute rheumatifm, at leaft in all thofe cafes which do not arife from direa ftimuli, there is an inflammatory affeaion of the parts, and a phlogiftic diathefis in the whole fyftem ; and upon thefe is founded the method of cure, which frequent experience has approved of. 461.] The cure therefore requires, in the firft place, an antiphlogiftic regimen, and particularly a total abftinence from animal food, and from all fermented or fpirituous li- quors ; fubftituting a vegetable or milk diet, and the plen- tiful ufe of bland diluent drinks. 462.] Upon the fame principle (449) at leaft with per- haps the fame exception as above, blood-letting is the chief remedy of acute rheumatifm. The blood ought to be drawn in large quantity, and the bleeding is to be repeated in proportion to the frequency, fullnefs, and hardnefs of the pulfe, and to the violence of the pain. For the moft part, large and repeated bleedings, during the firft days of the difeafe, feem to be neceffary, and accordingly have been very much employed: but to this fome bounds are to be fet; for very profufe bleedings occafion a flow re- covery, and, if not abfolutely effectual, are ready to pro- duce a chronic rheumatifm. 463.] To avoid that debility of the fyftem, which ge- neral bleedings arc ready to occafion, the urgent fymptom of pain may be often relieved by topical bleedings; and ^efpecially when any, fwelling and rednefs have come upon a joint, the pain of it may be very certainly relieved by fuch bleedings; but, as the continuance of the difeafe feems to depend more upon the phlogiftic diathefis of the whole fyftem, than upon the affeaion of particular parts, fo topical bleedings will not always fupply the place ofthe general bleedings propofed above.* •Thefe topical bleedings, however, have by repeated experience been found of effential advantage, efpecially when the partial inflammation has been very violent They are beft performed by leeches, many of which ou^ht to be ap- plied all over the inflamed part. Cupping has been long the favorite praftice of many phyficians, bnt it generally irritates more than the leeches ; vet in cafes that require immediate relief, it is preferable to them. The Glauber, or Eplom falts, are the moft convenient purges hi all cafer. of acute rheuma- tilm. Either of them may be given feparately, or join«d with the infufum iennx, as m the following formula : jRc« Intus. Senna ^iii. * Sal. Glauber. §ss. Tinct. Jalap. 3i« OF PHYSIC. 177 464.] To take off the phlogiftic diathefis prevailing in this difeafe. purging may be ufeful, if procured by medi- cines which do not ftimuhte the whole fyftem, fuch as neu- tral falts, and which have, in fome meafure, a refrigerant power. Purging, however, is not fo powerful as bleeding, in removing phlogiftic diathefis; and when the difeafe has become general and violent, frequent ftools are inconveni- ent, and even hurtful, by the motion and pain which they occafion. 465. J In acute rheumatifm, applications to the p:,inful parts are of little fervice. Fomentations, in the beginning of the difeafe rather aggravate, than relieve the pains. The rubefacients and camphire are more effeaual in re- lieving the pains; but generally they only fhift the pain from one part into another, and do little towards the cure of the general affection. Bliftering, applied to the pained part, may alfo be very effeaual in removing the pain from it; but will be of little ufe, except where the pains are much confined to one part. 466.] The feveral remedies mentioned from (450. to 454.) moderate the violence ofthe difeafe, and fometimes remove it entirely; but they fometimes fail in this, and leave the cure imperfea. The attempting a cure by large and repeated bleedings, is attended with many inconvenien- ces, (fee 140.) and the moft effeaual and fafe method of curing this difeafe, is, after fome general bleedings for tak- ing off, or at leaft diminifhing, the phlogiftic diathefis, to employ fweating, conducted by the rules laid down (168. and 169.)* 467.j Opiates, except where they are direaed to pro- cure fweat, always prove hurtful in every ftage of this dif- eafe. t Tinct.

Cream of tartar whey, mixed with twice its quantity of warm water, is a very proper drink to alfift the operation of purges. * Sweating is moft effectual in this difeafe, when produced by Dover's powder. The dofe of it is 12 or 15 grains, repeated at intervals, of two or three hours, till a fweat be produced. Diluent drinks are to be ufed with it : and it may be ncceffary to obferve, that they ought to be fuch as areJjand and by no means ftimulating; viz. barley-water, lintfeed-tea, thinwater-^uel. t Notwithftanding this caution, many practitioners ufe opiates, efpeci^ly Vol. I. Z A • 178 P R A C TICE 468.] The peruvian bark has been fuppofed a remedy in fome cafes of this difeafe ; but we have feldom found it ufeful, and in fome cafes hurtful. It appears to me to be fit in thofe cafes only, in which the phlogiftic diathefis is already much abated, and where, at the fame time, the exacerbations ofthe difeafe are manifeftly periodical, with 'confiderable remiffions interpofed.* 469. J Calomel and fome other preparations of mercury, have been recommended it the acute rheumatifm ; but I believe they are ufeful only in cafes of the chronic kind, or at leaft in cafes approaching to the nature of thefe. 470.] Having now treated fully ofthe cure of the acute rheumatifm, I proceed to treat ofthe cure of the chronic, which is fo frequently a fequel ofthe former. 471. J The phenomena ofthe purely chronic rheumatifm, mentioned in (438. and 439.) lead me to conclude, that its proximate caufe is an atony, both of the blood-veffels and of the mufcular fibres ofthe part affeaed, together with a degree of rigidity and contraaion in the latter, fuch as -frequently attends them in a ftate of atony. 472. J Upon this view ofthe proximate caufe the gene- ral indication of cure muft be, to reftore the aaivity and vigour ofthe vital principle in the part; and the remedies for this difeafe, which experience has approved of, are chief- ly fuch as are manifeftly fuited to the indication propofed. 473.] Thefe remedies are either external or internal. The external are, the fupporting the heat ofthe part, by keeping it conftantly covered with flannel; the increafing the heat ofthe part by external heat, applied either in a dry -or in a humid form ; the diligent ufe ofthe flefh-brufh, or when joined with camphor, to procure fweats in acute rheumatifm. This compound never fails to increafe the phlogiftic diarhelis, and confequently muft be hurtful. In the chronic rheumatifm, indeed, camphor and opium to- gether form a valuable medicine. The dofe is the following bolus : R. Camphor, gr. vi. Sp. Vini. gutt. x. Opii gr. i. Tart. Vitriol gr. xv. Syr. q. s.

Vtiterever an inflammatory diathefis prevails, the Peruvian barkis always an irrr^oper medicine, and it has been found by experience to be manifeftly feurtful in the beginning, or inflammatory ftate of the rhemnatifm. t OF phytic. m other means of friction ; the application of efearicity in fparks or Ihocks ; the application of cold * water by affu- hon or immerfion ; the applica-tion of effential oils of the moft warm and penetrating kind; the application of fait brine; and, laltly, the employment of cxercife, either of the part itfelf fo far as it can eafily bear it, or of the whole body bv riding or other mode of geftation. 474. J The interred remedies are,. 1. Large dofes of ef- fential oil drawn from refinous fubftances, fuch as turpen- tine ;J 2. Subftanees containing fuch oils, as guaiac ;,t 3. Volatile alkaline falts ; 4. Thefe, or other medicines di- reaed to procure fweat, (169.) and, laftly, Calomel,|[ or other preparation of mercury, in fmall dofes, continued for fome time. 475-] Thefe (462, 463.) are the remedies fuccefsfully employed in the purely chronic rheumatifm ; and there are ftill others recommended. As bleeding, general and to- pical, burning, bliftering, and iffues : but thefe appear to me to be chiefly, perhaps only, ufeful when the difeafe ftill partakes ofthe nature of acute rheumatifm 4. * This, when compared with art. 457 and others, feems to be a typogra- phical error, and the author meant warm. Pra&ice affords many inftances of chronic rheumatifm being occafioned by cold bathing. f Turpentine is an extremely healing oil, as indeed are all the effential oils ; its ufe therefore requires the greateft caution. The dofe is from 8 to 15 drops on a piece of fugar. Venice turpentine may be more conveniently given in the form of an emulfion, by diffolving it in water by means-of.yoiks of eggs. Two fcruples of turpentine is the ordinary dofe ; and when given in this li- quid and diluted llate, is much preferable to the oil. \ The officinal preparations of guaicum, are an extract of the wood* a folu- tion of the gum in rectified fpirit,. another in volatile alkali, and an empyreu- matical oil. The gum may be given in the quantity of 15 or 20 grains for a dofe, either in a belas, or made into an emulfion with yolk of egg and an ounce or two of water : In larger quantities it is too purgative. The volatile tlixer of the Edinburgh Pharmacopoeia is an excellent form, as the volatile fpirit promotes the medicinal virtue ofthe guaiacum. The dofe of it is from a drachm to half an ounce, morning and evening, in any convenient vehicle ; a tea-cupful of milk is the beft, as it (heaths in forne meafure the pungency of the medicine; Guaiacum is very conveniently joined with rhubarb and mag- nefia, when we find that(fuch a dofe of it, a.-, is neceffary for procuring a fuf- ficient opening, would be. too heating. A formula of this kind is defcribed in the note on article 558. |j Calomel, perhaps, has only beenferviceable in venereal cafes. | The diet in the cure of chronic rheumatifm ought tobe generous and full. In many cafes, efpecially among people in poor circumftances, good living, with two or three glaffcs of fherry in the day, has cured the difeafe without any medicines. One material circumftance ought not to be omitted: viz. that the cure is much impeded by coftivenefs : if, therefore, the guiacum does not procure two motions in the day, it will be neceffary to give along with it'iome warm laxative. The tiniftura facra is a proper medicine in thefe cafes : its dole is fi• jiu one to two ounces ' As is alfo the elixer facrum of the Edinburg; 180 PRACTICE CHAP. XIII. ©f t&e €Toot&ac&, or SDEontnlgia, 476.] i HAVE formerly confidered this difeafe as a fpe- cies of Rheumatifm, to be treated upon the lame principles as thofe delivered in the preceding chapter; but now, from more attentive confideration, I am led to confider the toothach as a diflinct difeafe. Whilft the moft of what has been delivered in the laft chapter proceeds upon the fup- pofition that the rheumatifm depends upon a certain ftate ofthe blood veffels and of the motion of the blood in them, without this being produced by the irritation of any acrid matter applied ; I judge, that in the toothach, though there are often the fame circumftances in the ftate of the blood veffels as in the cafes of rheumatifm, thefe circumftances in toothach always arife from the application of an acrid matter to the nerves of the teeth. 1 477. J This difeafe is often no other than a pain felt in a particular tooth, without any inflammatory affeaion be- ing at the fame time communicated to the neighboring parts. This, however, is rarely the cafe ; and for the moft part, together with the pain of the tooth, there is fome de- gree of pain and of inflammatory affeaion communicated to the neighboring parts, fometimes to the whole of thofe on the fame fide of the head with the affeaed tooth. 478. J This inflammatory affeaion feems to me to be al- ways an affeaion of the mufcles and of the membranous parts conneaed with thefe, without any tendency to fup- puration; and fuch an affeaion, as is excited by cold in fimilar parts elfewhere. It is from thefe circumftances that I conclude the affeaion to be of the rheumatic kind. 479. J It is poffible that the mufcles and membranes of the jaw may be affeaed by the fame caufes which produce the rheumatifm in other parts; and it is alfo poffible, that a rheumatic diathefis at firft produced by irritation, may fubfift in the mufcles and membranes of the jaw, fo that the inflammatory affeaion may be renewed by certain cau- fes without any new application of acrid matter: But I am College Pharmacopccia, its dofe may be fror a drachm to half an ounce, ss eccafion may require. OF PHYSIC. 181 pcrfuaded that either of thefe occurrences are very rare, and I have never been able to afcertain ahy cafes of tooth- ach to be of thefe kinds. I confider it, therefore, as high- ly probable that this rheumatic affection of the jaws winch we name toothach, is always dependent upon fome imme- diate application of acrid matter to the nerves ofthe teeth. 480.J It is however to be obferved, that this applica- tion of acrid matter does not always excite a pain in the tooth itfelf, or an inflammatory affeQion of the neighbor- ing parts; but that it v*ery often operates by producing a diatheiis only; fo that cold applied to the neighboring parts does excite both a pain in the tooth, and an inflam- matory affeaion of the neighboring parts which did not appear before. There feems to be alfo certain ftates of the body, which operate upon the fame diathefis fo as to produce toothach. Such feems to be the cafe of pregnant women, who are more liable to toothach than other women. There are probably alfo fome cafes of increafed irritability which render perfons more fubjea to toothach. Thus women are more liable to the difeafe than men, and particularly women liable to hyfteric affeaions. 481.] The acrid matter producing this difeafe feems to be generated firft in the hard fubftances of the teeth; and as it often appears firft upon the external furface of thefe, it might be fufpeaed to arife from the application of exter- nal matters to the teeth: But as the production of this acrimony is often begun in the internal cavity of the teeth, where the operation of external matters cannot be fufpefct- ed, and as even when it begins upon the external parts of the teeth, the operation of the caufe is at firft in a fmall portion ofthe teeth only, that it is difficult to fuppofe that any matter externally applied could a£t in fuch a partial manner; fo it is prefumed that the acrid matter occafion- ing the toothach is produced by fome vice originating in the fubflance of the tooth itfelf. When it begins upon the external furface, it is on the enamel; but upon the inter- nal furface, it muft be in the bony part. From what caufes it arifes in either of thefe fubftances, I do not at all know; but I fufpea diat it often arifes from fome more general fault in the fluids of the body. The frequent ufe 182 PRACTICE of mercury, efpecially when thrown much upon the mouthy and the ftate ofthe fluids in feurvy, feem both of them to- give a difpofition to a caries in the teeth; and it is poffi- ble that fome other acrimonious ftates of the fluids may have the fame effea. 482.] A caries in fome'part ofthe teeth, whether arif- ing upon their internal furface or upon their external, pro. ceedingfo far as to reach the nerves in the cavity of the teeth, is pretty manifeftly the caufe of toothach, and of the firft attacks of it; but when the cavity of (he teeth has been opened, fo that the external air or other matters can reach that cavity, thefe are often the exciting caufes of toothach, and ferve to prove in general, that acrid mat. ters applied to the nerves occafion the difeafe. 483. J What is the nature of the matter produced in the caries ofthe teeth, I do not uhderftand, nor have I found any proper correaor of it; but I prefume it to be ofthe putrid kind, as it often taints the breath with a fetid odo% 484.] In the cure of this difeafe, a long experience has fhown, that the extraaion of the carious tooth proves the moft effeaual, and very often the only effeaual, remedy of the difeafe. But as in fome cafes this extraaion is not proper, and as in many cafes it is obttinately avoided, other means of curing the difeafe, or at leaft of relieving the pain, have been fought for and much praaifed. 485.] Among thefe remedies, thofe arc likely to be the moft effectual which entirely deftroy the affeaed nerve, or at leaft fo much of it as is expofed to the aaion ofthe acrid matter in the tooth. Wnen an opening is made into the cavity of the tooth, the nerve of it may be deftroyed moft certainly by the aaual cautery ; and it may alfo poffibly be done by the application of potential cauftics, either of the alkaline or acid kind. 486.] When thefe remedies cannot be rendered effec- tual, relief may often be obtained by dimini thing the fen- fibility ofthe nerve affeaed, by die application of opium, or of the more acrid aromatic oils,* and direaiy to the nerve in the tooth. It appears alfo, that the fenfibility of the affeaed nerve may often be for fome time diminiihed * The Oleum Origani is the oil generally ufed for this purpofe. Great care muft be taken in ufing either thefe acrid effential oils, or the vr.riolic or other mineral acids, that n.opart of them touch the gums. U 1? PIT Y SIC. 183 by the external application of opium to the extremities of thofe nerves in the fkin, which are branches ofthe fame fifth pair of nerves with thofe of the teeth. 487.] When the difeafe confifts entirely in a pain ofthe nerve of the tooth, without any confiderable affeaion com- • municated to the neighboring parts, the remedies already mentioned are thofe efpecially to be employed; but when the difeafe confifts very much in an inflammatory affeaion of the mufcles and membranes of the jaw, and when at the fame time there is little or no accefs for the abovemen- tioncd remedies to the affeaed nerve, other meafures are to be employed for relieving the difeafe. 488. | If the difeafe he attended with any general phlo- giftic diathefis of the fyftem, or with any confiderable de- gree of pyrexia, a general bleeding may be ufeful in reliev- ing the dileafe; but thefe circumftances occur very rarely, and the difeafe is for the molt part a purely topical affec- tion; in which, as I obferved before, a general bleeding is of very little fervice. As this difeafe, however, is a to- pical inflammation, it might be fuppofed that topical bleedings would be very ufeful, and fometimes they are fo; but it in feldom that their effeas are either confider- able or permanent. The reafons of this I take to be that the difeafe docs not confift in an affeaion of the blood- vefiels alone, as in the ordinary cafes of rheumatifm; but in a peculiar affeaion of the fibres both of the mufcles and ofthe veffels ofthe part induced by irritation. The inef- ficacy of Lopical bleedings is with me a proof of the difeafe being of the latter kind. 489.] The remedies therefore neceffary to give relief in this difeafe, are thofe which take off the fpafm of the veffels, and efpecially of the mufcles and membranes affect- , ed. Such are bliftering, brought as near to the part affea- ed as can be conveniently done ;* and fuch are alfo increaf- * Blifters are applied moft fuccefsfully behind the ears, fuch applications, however, are always tfoublefome ; and their effects are often doubtful, other milder ftimulants frequently anfwer all the intention of blifters, and by' many praaitioners are thought to be equallv efficacious. The applications general- ly ufed are camphorated fpirit, or * ol'atile alkali. This laft, either alone or mixed with an equal quantity of oil of almonds rubbed on the jaw, the part being kept warm by apiece of flannel, has often been found extremely ufeful Warmth, any how produced on the part, always gives relief; while on the contrary, cold always ejiafperates the fymptoms ; hence the propriety of co- vering tlie jaws with flannel, and ayoiding a cold, ftreajn of air. J 184 PRACTICE ed excretions excited in the neighbouring parts, as of the faliva and mucus of the mouth by the ufe of acrid mafti- catories * It is often fufficient to excite a ftrong fenfation in the neighboring parts ; -as by can de luce, fpirit of la- vender, or Hungary water fnuffed up the noftrils; or by the vitriolic aether properly applied to the cheek. It is upon the fame footing that I fuppofe brandy or other ar- dent fpirit held in the mouth is often of fervice. 490. J There are cafes of toothach in which it does not appear that the difeafe arifes from an acrid matter imme- diately applied to the nerve ofthe tooth ; but from the ex- ternal application of cold, or fome other caufes immedi- ately applied to the mufcles and membraircs of the jaw; and which therefore feem to require fome remedies differ- ent from thofe above mentioned. But in all fuch cafes, it is to be fufpecled. that the effects of cold or of feme other fuch caufes are owing to a diathefis produced by an acrid matter applied to the nerve of a tooth, ana conti- nuing in fome meafure to aa there ; and we have accord- ingly often found, that the aaion of thofe external caufes were to be obviated only by the extraaion of the-tooth from which the diathefis had arifen.

Thefe arc horfe-radifh, fcurvy-grafs, the greater celandine, with fome others ; but the radix pyrethri is the beft.

From fuch a hiftory I expect that a general charaaer mav be given ; and fuch I think is the following, as given in the laft edition of our Nofology: Gen. XXIII. PODAGRA. Morbus hsereditarius, oriens fine can la externa evidente, fed praeeunte plerum- que ventriculi affeclione infolita; pyrexia ; dojor ad arti- culum et plerumque pedis pollici, certe pedum et manuum junauris, potiffimum infeftus; per intervalla revertens, et faepe cum ventriculi et internarum partium affeaionibus al- ternans. 492.] The Gout is generally a hereditary difeafe: but fome perfons, without hereditary difpofition, feem to acquire it; and, in fome a hereditary difpofition maybe coun- teracted by various caufes. Thefe circumftances may feem to give exceptions to our general pofition; but the facts direaiy fupporting it are very numeroas. 493.] This difeafe attacks efpecially the male fex: but it fometimes, though more rarely, attacks alfo the female.* * Hippocrates fays, that women feldom have the gout, and never before the disappearance of the catamenia. In his time and country,perhaps the la- dies were more temperate than they were in other ages and in other places. We find the gout a familiar difeafe among the Roman ladies ; which Seneca in his 95th epiftle, jullly afcribes to the luxurious living and debaucheries, in which they iniulged without controul. As the whole of that epiftle is an excellent account of the direful effects of high living and debauchery, it may not be unacceptable to the young praditioner, who perhaps, might otherwife be unacquainted with fo jutt a deicription df luxurious living, and its concom- itant evils. Independent of its containing a minute relation of Roman cuf- toms, which makes it a valuable morfel for antiquaries, it may be read with peculiar advantage by the young phyfician. As an apology for giving it iu the original, I fliall fay of Seneca, what an elegant Englifh writer fays of Ci- cero ; That any tranflation of his nervous language, is like the faint glimmer- ings of a taper compared with the blazinglight of the meridian fun.

IS/ 495.] The gout attacks efpecially men of robuft and large bodies, men of large heads, of full and corpulent ha. bits, and men whofe fkin is covered with a thicker reie mu- iosum, which gives a coarfer furface. 496. ] I f with the ancients, we might afcertaih, by certain terms, the temperaments of men, I would fay, that the gout attacks efpecially men of a choleric-sanguine temperament, and that it very feldom attacks the purely fanguine or me- lancholic. It is however^ very difficult to treat this mat- ter with due precifion. 497.] The gout feldom attacks perfons employed in con- ftant bodily labour, or perfons who live much upon vege- table aliment. It is alfo faid to be lefs frequent among thofe people who make no ufe of wine or other fermented liquors. 498. J The gout does not commonly attack men, till af- ter the age of five and thirty > and generally not till a ftill later period. There are indeed inftances of the gout oc- curring more early ; but thefe are.few in eomparifon of the numbers which agree with what we have given as the general rule. When the difeafe does appear early in life, it feems to be in thofe in whom the hereditary dif- pofition is very ftrong, and to whom the remote caufes to be hereafter mentioned have been applied in a coofider- able degree. 499.] As the gout is a hereditary difeafe, and affects ef- pecially men of a particular habit, its remote caufes may be confidered as predifponent and occafional. 500. J The predifponent caufe, fo far asexpreffed by ex- ternal appearances or by the general temperament we have already marked ; and phyficians have been very can- fident in affigning the occafional caufes: but, in a difeafe depending fo much upon a predifpofition, the afftgning the occafional caufes muft be uncertain ; as in the predifpo- fed, the occafional caufes may not always- appear, and in perfons not predifpofed, they may appear without effea. This uncertainty muft particularly affea the cafe of the gout; but I fliall offer what appears to me moft probable on the fubjea. 501.] The occafional caufes of the gout feem to be of two kinds. Firft, thofe which induce a plethoric ftate of ISS PRACTICE the body. Secondly, thofe which, in plethoric habit?, in- duce a ftate of debility. 502.] Of the firft kind are a fedentary indolent manner of life, a full diet of animal food, and the large ufe of wine or of other fermented liquors. Thefe ciicumftances com- monly precede the difeafe; and if there fhould be any doubt of their power of producing it, the faa, however, will be rendered fufticiently probable by what has been obferved in 497. 503.] Of the fecond kind of occafional caufes which induce debility are, execis in venery;* intemperance in the ufe of intoxicating liquors ;t indigcttion, produced either by the quantity or quality of aliments;J much ap- plication to ft udy or bufinefs ;|| night-watching:** execf- five evacuations ;tt the ceafing of ufual labom ;J+ the fud- den change from a very full to a very fpare diet;|||| the large ufe of acids and acefcents ;(*) and, laftly, cold(t) ap- plied, to the lower extremities. * Why excefs of venery fhould be caufe of gout, has much engaged the at- tention of medical writers, and various rcafous have been given why it fhould produce fuch an effect. There is not the leaft doubt of the-fact., though fome authors have ventured to deny it, and have excluded the excefs of venery from being a caufe of gout. It produces gout not primarily, but fecondarily, if I may be allowed the expreflion, by inducing a general ftae of debility, and by weakening the power of digeftion, both of which circumftances are caufes of the gout. f By intemperate drinking, the action of the ftomach and bowels becomes extremely feeble and languid, if it be not wholly deftroyed : hence continual indigeftions, to which the origin of the gout is attributed. J Both the quantity and the quality of the aliments may produce indigefti- on ; and hence the indulging in too great a-quantity of aliment, as well as in that which is of an indigeftible nature, are fecondary caufes of the gout: viz. caufes which induce a ftate of debility. || Much application to ftudy may d< ubtlefs induce Indigeftion, and thus increafe the general ftate of debility: it is not, however, by intenfe, or deep thinking merely, that men grow pale amid their books, but by the fedentary life which men generally lead, and the untimely lucubrations in which they inconfiderately indulge. Much application to bufinefs can ci.l. be an occafi- onal caufe of the gout, when the bufinefs requires a fedentary and inactive life ; but as moft bufinefs requires activity, attention to bufinefs is feldom the caufe of the gout. ** The want of fleep is always a caufe of indigeftion, and increafes debili- ty more perhaps when carried to excefs, than any other of the circumftances mentioned by the author. ft That large evacuations induce debility is fuftjciently evident. \\ Nothing more effecrually promotes digeftion than proper exercife ; the leaving off accuftomed labor muft therefore necefiarily induce indigeftion and confequently debility. |||| Why this induces debility is evident. See note on article 548. , (*) That acids, by impairing the digeftive powers of the ftomach, may pro- duce debility, is what every practitioner allows. (f) How cojd thus applied, can produce a ftate of debility, is not very evi- OF PHYSIC. 189 504 j The firft (502.) feem to aa by increafing the pre- difpofition. The laft (503.) are commonly the exciting caufes, both of the firft attacks, and of the repititions of the difeafe. 505.] It is an inflammatory affeaion of fome of the joints, which efpecially conftitutes what we call a parox- yfm of the gout. This fometimes comes on fuddenly withont any warning, but is is generally preceded by fev- eral fymptoms; fuch as the ceafing of a fweating which the feet had been commonly affected with before; an un- ufual coldnefs ofthe feet and legs; a frequent nuinbnefs, alternating with a fenfe of prickling along the whole ofthe lower extremities; frequent cramps ofthe mufcles of the legs; and an unufual turgefcence of the veins. 506.J While thefe fymptoms take place in the lower extremities, the whole body is affeaed with fome degree of torpor and languor, and the funaions of the ftomach in particular are more or lefs difturbed. The appetite isdi- minifhed, and flatulency, or other fymptoms of indigefti- on, are felt, Thefe fymptoms, and thofe of (505.) take place for feveral days, fometimes for a week or two, be- fore a paroxyfm comes on: but commonly, upon the day immediately preceding it, the appetite becomes great- er than ufual. 507.] The circumftanees of paroxyfms are the follow- ing. They come on moft commonly in the fpring, and fooner or later according as the vernal heat fucceeds iooner or later to the winter's cold; and perhaps fooner or later alfo according as the body may happen to be more or lefs expofed to viciffitudes of heat and cold. 508.J The attacks are fometimes felt firft in the even- ing, but more commonly about two or three o'clock of the morning. The paroxyfm begins with a pain affeaing one foot, moft commonly in the ball or firft joint of the great toe, but fometimes in other parts of the foot. With the coming on of this pain, there is commonly more or lefs of cold fhivering, which, as the pain increafes, gradu- ally ceafes, and is fucceeded by a hot ftage of pyrexia, which continues for the fame time with the pain ftfelk dent. It is, however, one of the occafional caufes of gout, as experie»ce fuf- ficientlv teftitlcs. Htf 190 PR......v.- From the firft attack, the pain becomes by degrees more violent, and continues in this ftate with great reftleffnefs of the whole body, till next midnight, after which it gra- dually remits; and, after it has continued for twenty-four hours from the firft attack, it commonly ceafes very en- tirely, and with the coming on of a gentle fweat, allows the patient to fall afleep. The patient, upon coining out of this fleep in the morning, finds the pained part affected with fome rednefs and fwelling, which, after having con- tinued for fome days, gradually abate. 509.] When a paroxyfm has thus conae on, although the violent pain after twenty-four hours be confiderably abated, the patient is not entirely relieved from it. For fome days he has every evening a return of more confi- derable pain and pyrexia, and which continue with more or fefs violence till morning. After continuing in this manner for feveral days, the difeafe fometimes goes entire- ly .off, not to return till after a long interval. 5 to.] When the difeafe, after having thus remained for fome time in a joint; ceafes very entirely, it generally leaves the perfon in very perfea health, enjoying greater eafe and alacrity in the funaions of both body and mind, than he had for a long time before experienced. 511.] At the beginning of the difeafe, the returns of it are fometimes only once in three^or four years : but, ^fter fome time, the intervals become fhorter, and the attacks become annual; afterwards they come twice each year, and at length recur feveral times during the whole courfe of autumn, winter, and fpring; and as it happens that, when the fits are frequent, the paroxyfms become alfo longer, fo, in the advanced ftate of the difeafe, the pati- ent is hardly ever tolerably free from it, except perhaps for two or three months in fummer. 512.] The progrefs ofthe difeafe is alfo marked by the parts which it affeas. At firft, it commonly affeas one foot only; afterwards every paroxyfm affeas both feet, the one after the other; and, as the difeafe continues to recur, it not only affeas both feet at once, but after hav- ing ceafed in the foot which was fecondly attacked, returns again into the foot firft affeaed, and perhaps a fecond time alfo into the other. Its changes of place are not only from. OF PHYSIC. 191 one foot to the other, but alfo from the feet into other joints, efpecially thofe of the upper and lower extremities; fo that there is liardly a joint of the body that is not, on one occafion or other, affeaed. It fometimes affects two different joints at the fame time; but more commonly it is fevere in a fmgle joint only, and paffes fucceflively from one joint to another; fo that the patient's affliction is often protraaed for a long time. 513.] When the difeafe has-often returned, and the pa- roxyfms have become very frequent, the pains are com- monly lefs violent than they were at firft; but the patient is more affeaed with ficknefs, and the other fymptoms of the atonic gout, which fhall be hereafter mentioned. 514.] After the firft paroxyfms of the difeafe, the joints which have been affeaed are entirely reftored to their form- er fupplenefs and ftrength; but after the difeafe has recurr- ed very often, the joints affeaed do neither fo fuddenly nor fo entirely recover their former ftate, but continue weak and ftiff; and thefe effeas at length proceed to fuch a degree, that the joints lofe their motion altogether. 515.] In many perfons, but not in all, after the difeafe has frequently recurred, concretions of a chalky nature are formed upon the outride of the joints, and for the moft part immediately under the fkin. The matter feems to be depofited at firft in a fluid form, but afterwards becomes dry and firm. In their dry ftate, thefe concretions are a friable earthy fubftance, very entirely foluble in acids. After they have been formed, they contribute, with other circumftances, to deftroy the motion of the joint. 516.] In moft perfons who have laboured under the gout for many years, a nephritic affection comes on, and difca- vcrs itfelf by all the fymptoms which ufually attend calcu- lous concretions in the kidneys, and which we fhall have occafion to defcribe in another place. All that is neceffary to be obferved here is, that the nephritic affeaion alternates with paroxyfms of the gout; and that the two affeaions, the nephritic and the gouty, are hardly ever prefent at the fame time. This alfo may be obferved, that children of gouty or nephritic parents, commonly inherit one or other of thefe difeafes; but whichever may have been the prin- cipal xiifeafe of the parent, fome of the children have the 152 PRACTICE one, and fome the other. In fome of them, the nephritic affeaion occurs alone, without any gout fupervcning; and this happens to be frequently the cafe ofthe female off- fpring of gouty parents. 5y.] In the whole ofthe hiftory already given I have defcribed the moft common form ofthe difeafe; and which therefore, however divcrfified in the manner I have faid, may be ftill called the regular ftate of the gout. Upon oc- ca! on, however, the difeafe affumes different appearan- ces;^ but, as I fuppofe the difeafe to depend always upon a certain diathefis or difpofition ofthe fyftem; fo every appearance which we can perceive to depend upon that fair.e difpofitionj 1 fliall confider as a fymptom and cafe of the <*out. The principal circumftance in what we term the Regular gout, is the inflammatory affeaion of the joints;; and, whatever fymptoms we can perceive tobe conneaed with, or to depend upon, the difpofition which produces that inflammatory affeaion, but without its tak- ing place, or being prefent at the fame time, we name the Irregular gout. 518.] Of fuch irregular gout there are three different ftates, which I name the atonic, the retrccedent, and the miyplaced gout. 519.] The atonic ftate is when the gouty diathefis pre- vails m the fyftem, but, from certain caufes. does not pro- duce the inflammatory affeaion ofthe joints. In this cafe, the morbid fymptoms which appear are chiefly affeaions of the ftomach; fuch as lofs of appetite, indigeftion, and its various circumftances of ficknefs, naufea, vomiting, flatulency, acrid ertfetations,. and pains in the region of the ftomach. Thefe fymptoms are frequently accompa- nied with pains and cramps in feveral parts of the trunk, and the upper extremities of the body, which are relieved by the difcharge of wind from the ftomach. Together with thefe affeaions of the ftomach there commonly oc- curs a coftivenefs; but fometimes a loofenefs with cholic * Thefe different appearances which the gout affumes, are extremely unlike the regular gout above defcribed; the young praftitioiier ought therefore to pay peculiar attention to them, that when he obferves them in patients, he mav not think them fymptoms of other difeafes, or even miftake them for primary difeafes. Errors of this kind are frequently committed by ignorant praditioners, to their own difevedit and the danger of their patient's life. e F P H Y S I C. 193 pains. Thefe affeaions of the alimentary canal arc often attended with all the fymptoms of hypochondriafis; asde- jedion of mind, a conftant and anxious attention to the llighteft feelings, an imaginary aggravation of thefe, and an apprehenfion of danger from them. In the fame atonic gout, the vifcera of the thorax alfo are fometimes affected, and palpitations, faintings,and afth- ma, occur. In the head alfo occur, headachs, giddinefs, apopfeaic and paralytic affeaions. 5'iO.] When the feveral fymptoms now mentioned occur in habits having the maiks of a gouty difpofition, this may be fufpected to have laid the foundation of them, and efpe- cially when either, in fuch habits, a manifeft tendency to the inflammatory affeaion has formerly appeared ; or when the fymptoms mentioned are intermixed with, and are re- lieved by, fome degree ofthe inflammatory gout. In fuch cafes there can be no doubt of confidering the whole as a ftate of the gout. 521.] Another ftate ofthe difeafe I name the retrocedent gout. This occurs when an inflammatory ftate ofthe joints has, in the ufual manner, come on, but which, without a- rifing to the ordinary degree of pain and inflammation, or, at leaft, without thefe continuing for the ufual time, and re- ceding gradually in the ufual manner, they fuddenly and entirely ceafe, while fome internal part becomes affeaed. The internal part moft commonly affeaed is the ftomach, which is then affeaed with anxiety, ficknefs, vomiting, or violent pain ; but fometimes the internal part is the heart, which gives occafion to afyncope ; fometimes it is the lungs which is affeaed with afthma ; and fometimes it is the head, giving occafion to apoplexy or palfy. In all thefe cafes, there can be no doubt ofthe fymptoms being all a part of the fame difeafe, however different the affeaion may feem to be in the parts which it attacks. 522.] The third ftate of irregular gout, which we name the misplaced, is when the gouty diathefis, inftead of pro- ducing the inflammatory affeaion of the joints, produces an inflammatory affeaion of fome internal part, and which appears from the fame fymptoms that attend the inflam- mation of thofe parts arifing from other caufes. Vsii.. I. B b 19i PRACTICE Whether the gouty diathefis does ever produce fuch in- flammation of thcintcrnal parts without having firft produc- ed it in the joints, or if the inflammation ofthe internal • part bealwaysa tranflation from the joints previoufly affect- eel, I dare not determine ; but, even fuppofnv* the latter to be always the cafe, I thank the difference of tire affection ofthe internal part muft ftill diftinguifh the mifplaced from what I have named the Retrocedent Gout. 523.] What internal parts may be affetted by the mif- pkeed gout I cannot precifely fay, becaufe I have never met with any cafes of the mifplaced gout in my practice ; and I find no cafes of "It diitinttly marked by praaical wri- ters, except that of a pneumonic inflammation. 524.] There are two cafes of a tranflatedgout; the one of which is an affection of the neck of the bladder, pro- ducing pain, ftrangury, and a catarrhus veficae : The other is an affection of the rectum, fometimes by pain alone 111 that part, and fometimes by hemorrhoidal fwelling there. In gouty perfons, I have known fuch affeaions alternate with inflammatory affeaions ofthe joints : But whether to refer thofe affections to the retrocedent, or to themifplac- •ed gout, I will not prefume to determine. 525.] From the hi'tory which I have now delivered of the gout, I-think it may be difeerned under all its various appearances. It is, however, commonly fuppofed, that there are cafes in which it may be difficult to diftinguifh gout from rheumatifm, and it is poffible there may be fuch cafes : but, for the moft part, the two difeafes may be dif- tinguifhed with great certainty by obferving the predifpo- fition, the antecedents, the parts affeaed, the recurrences of the difeafe, and its connection with the other parts ofthe fyftem ; which circumftances, for the moft part, appear very differently in the two difeafes. 526.] With refpea to the gout, our next bufinefs is to inveftigate its proximate caufe; which muft be a difficult tafk, and I attempt it with fome diffidence. 527.] Upon this fubjea, the opinion which has gene- rally prevailed is, that the gout depends upon a certain morbific matter, always prefent in the body; and that this matter, by certain caufes, thrown upon the joints or other parts, produces the feveral phenomena of the difeafe. OF PHYSIC. 1SS 528.] This doarine, however ancient and general, ap- pears to me very doubtful; for, Firft, There is no direct evidence of any morbific mat- ter being prefent in perfons difpofed to the gout. There are no experiments or obfervations which mow that the blood, or other humours of gouty perfons, are in any ref- pect different from thofe of other perfons. Previous to attacks of the gout, there appear no marks of any morbid ftate of the fluids; for the difeafe generally attacks thofe perfons who have enjoyed the moft perfect health, and.ap- pear to be in that ftate when the difeafe comes on. At as- certain period of the difeafe, a peculiar matter indeed ap- pears in ;,outy perfons; (515.) but this,, which does not appear in every inftar.ee, and which appears only after the difeafe has fubfifted for a long time, feems manifeftly to be the effect, not the caufe, of the difeafe. Further, though there be certain acrids which, taken into the body,. feem to excite the gout, (503.) it is probable that thefe acrids operate otherwife in exciting the difeafe, than by af-' fording the material caufe of it. In general, therefore^ there is no proof of any morbific matter being the caufe of the gout. Secondly, The fuppofitions concerning the particular nature ofthe matter producing the gout, have been fo va- rious and fo contradictory to each other, as to allow us to conclude, that there is truly no proof of the cxiftence of any of them.. With refpefct to many of thefe fuppofitions, they are fo inconfiftent with chemical philcfbphv. and with the laws of the animal.economy, that they muft be entirely rejected. Thirdly, The fuppofition of a morbific matter being the caufe ofthe gout, is n.uconfiitent with the phenomena of ihe difeafe, par;ici:Iaily, with its frequent and fudden trauflations from one part to another. Fourthly, The fuppofition is further rendered impro- bable by thw, that, if a morbific matter did cxift, ir.(v--_ ration fhould be fimilar in the feveral pints which it at- tacks; whereas it feems to be very dilfeent, being |hn .- lant, and exciting inflammation in the lointr, but fecauve and dellroying the tone in the ftomach: Whicn, coon -the fuppofition of particular matter aaing in both cafes, is no^. to be explained by any difference- in the part affeaed. 196 PRACTICE Fifthly, Some faas, alledged in proof of a morbific matter, are not fufficiently confirmed, fuch as thofe which would prove the difeafe to be contagious. There is, how- ever, no proper evidence of this, the faas given being not only few, but exceptionable; and the negative obfer- vations are innumerable. Sixthly, Some arguments brought in favour of a mor- bific matter, are founded upon a miftaken explanation. The difeafe has been fuppofed to depend upon a morbific matter, becaufe it is hereditary: But the inference- is not juft; for moft hereditary difeafes do not depend upon any morbific matter, but upon a particular conformation of the ftruaure of the body, tranfmitted from the parent to the offspring; and this laft appears to be particularly the cafe in the gout. It may be alfo obferved, that heredita- ry difeafes, depending upon a morbific matter, always ap- pear much more early in life than the gout commonly does. Seventhly, The fuppofition of a morbific matter being the caufe of the gout, has been hitherto ufelefs, as it has not fuggefted any fuccefsful method of cure. Particular fuppofitions have often corrupted the pra6licc, and have • frequently led from thofe views which might be ufeful, and from that praaice which experience had approved." Further, though the fuppofition of a morbific matter has been generally received, it has been as generally negfeaed in praaice. When the gout has affeaed the ftomach, no- body thinks of correaing the matter fuppofed to be pre- fent there, but merely of reftoring the tone of the moving fibres. Eighthly, The fuppofition of a morbific matter is quite fuperfluous; for it explains nothing, without fuppofing that matter to produce a change in the ftate of the moving powers; and a change in the ftate of the moving powers, produced by other caufes, explains every circumftance, J without the fuppofition of a morbific matter; and, to this . purpofe, it may be obferved, that many of the caufes (503.) exciting the gout, do not operate upon the ftate of the fluids, but directly and folely upon that of the mov- | ing powers. Laftly, The fuppofition of a morbific matter is alfo fu- U h PHASIC. 19* ■ perfluous; becaufe, without any fuch fuppofition, I think the difeafe can be explained in a manner more confiftent with its phenomena, with the laws of the animal economy, and with the method of cure which experience has approv- ed. I now proceed to give this explanation; but, before en- terim^ upon it, I muft prfemife fome general obfervations. 529.] The firft obfervation is, that the gout is a difeafe of the whole fyftem, or depends upon a certain general conformation and ftate of the body; which manifeftly ap- pears from the faas mentioned from (493. to 496.) But the general ftate of the fyftem depends chiefly upon the ftate of its primary moving powers; and therefore the gout may be fuppofed to be chiefly an affeaion of thefe. 530.] My fecond obfervation is, that the gout is manifeftly an affection of the nervous fyftem;* in which the primary moving powers of the whole fyftem are lodged. The oc- cafional or exciting caufes (503.) are almoft all fuch as ad direaiy upon the nerves and nervous fyftem; and the greater part of the fymptoms of the atonic or retrocedent gout are manifeftly affeaions of the fame fyftem (519. and 521.J This leads us to feek for an explanation of the whole ofthe difeafe in the laws of the nervous fyftem, and particularly the changes which may happen in the ba- lance of its feveral parts. 531.] My third obfervation is, that the ftomach, which has fo univerfal a confent with the reft ofthe fyftem, is the internal part that is the moft frequently, and often very confiderably affeaed by the gout. The paroxyfms of the difeafe are commonly preceded by an affeaion ofthe ftom- ach ; (506.) many ofthe exciting caufes (503.) aa firft up- on the ftomach; and the fymptoms of the atonic and retro- cedent gout (519. 521.) are moft commonly and chiefly af- feaions ofthe fame organ. This obfervation leads us to remark, that there is a ballance fubfifting between the ftate ofthe internal and that of the external parts ; and, in par- ticular, that the ftate ofthe ftomach is conneaed with that • Boerhaave after defcribing the difeafe, fays, Aphorifm, 1262. '<■ From all which it appears that the proximate caufe of the gout is a vitiated ftate ofthe moft minute, and confequently nervous veffelj of the budv; and aU'o of that fluid which flows through the nerves." 198 PRACTICE ofthe external parts (44.) fothat the ftate of tone in the one may be communicated to the other. 53-.] Thefe obfervations being premifed, I fhall now oner the following pathology of the gout. . In fome perfons there is a certain vigorous and pletho- ric ftate ofthe fyftem (495.) which, at a certain period of life, is liable to a lofs ol tone in the extremities. (498.) (505.) This is in fome meafure communicated to the wr.ole fyftem, but appears more efpecially in the functions ofthe ftomach. (506.) When this lofs of tone occurs while the energy of the brain ftill retains its vigour, the vis medica- trix naturay| excited to reftore the tone ofthe parts ; and accomplifrW it by exciting an inflammatory affection in fome part cf the extremities. When thi^ has fubfifted for forne days, the tone of the extremities, and of the whole fyftem, are reftored, and the patient returns to his ordina- nary ftate of health. (510.) 533-] This is the courfe of things, in the ordinary form of the difeafe, which we name the regular gout; but there are circumftances ofthe body, in which this courfe is in- terrupted or varied. Thus when the atony (505. 506.) has taken place, if the reaction (508.) do not fuccecd, the atony continues in the ftomach, or perhaps in other inter- nal parts, and produces that ftate which we have, for rea- fons now obvious, named the atonic gout. 534-] A fecond cafe of variation in the courfe ofthe gout is, when, to the atony, the reaction and mtiammation have to a certain degree fuccecded; but, from caufes ci- ther internal or external, the tone of the extremities, and perhaps of the whole fyftem, is weakened; fo that the in-. . flammatory ftate, before it had either proceeded to the de- gree, or continued for the time, requifite for rcftoring the tone ofthe fyftem, fuddenly and entirely ceafes. Hence the ftomach, and other internal pans, rclapfc into the ftate of atony; and perhaps have this increafed bv the ato- ny communicated from the extremities: All which appear* in what we have termed the retrocedent gout. 535-] A third cafe of variation from the ordinary- coiirfe of the gout, is, when, to the atony ufually preceding, an inflammatory reaaion fully fuccceds; but has its ufual deter- mination to thejoints by fome circumf bailees prevented- and- OF PHYSIC. 199 is therefore direaed to an internal part, where it produces an inflammatory affection, and that ftate of things which we have named the misplaced go it. 536.] WTc have thus offered an explanation of the cir- cumitances of the fyftem in the feveral ftates of the gout; and this explanation we fuppofe to be confiftent with the phenomena ofthe difeafe, and with the laws of the animal economy. There are indeed, with refpea to the theory of the difeafe, feveral queftions which might be put, to winch we have not given any-anf.ver. But, though per- haps we could give an anfwer to many of thefe queftions, it does not here appear neceffary; as at prefent we intend only to eftablifh fuch general facts with regard to this dif- eafe, as may lay a foundation for the cure of it, fo far as experience has enabled us to profecute it. Proceeding, therefore, upon the feveral parts of the pathology given, as fo many matters of faa, I fhall now confider what may be attempted towards the cure of the difeafe. 537]. In entering upon this, I muft obferve, in the firft place, that a cure has been commonly thought impoffible; and we acknowledge it to be very probable, that the gout as a difeafe of the whole habit, and very often depending upon original conformation, cannot be cured by medicines, the effects of which arc always very tranfitory, and feldom extend to the producing any confiderable change of the whole habit. 538.] It would perhaps have been happy for gouty per- fons, if this opinion had been implicitly received by them ; as it would have prevented their having been fo often the dupes of felf-interefted pretenders, who have either am uf- ed them with inert medicines or haverafhly employed thofe . of the moft pernicious tendency. I am much difpofed to believe theimpoffibility of a cure of the gout by medicines; and more cvrtainly ftill incline to think, that whatever may be the poffible power of medicines yet no medicine for cu- ring the gout has hitherto been found. Although almoft every age has prefented a new remedy, yet all hitherto of- fered have very foon been either neglected as ufelefs, or condemned as pernicious. 539-J Though unwilling to admit the power of medi- cines, yet I contend that a great deal can be done towards 200 PRACTICE th« cure of the gout by a regimen : And from what has been obferved (497.) 1 am firmly perfuaded, that any man who. early in life, will enter upon the conftant practice of bodily labour, and of abftinence from animal food, will be preferved entirely from difeafe. Whether there be any other means of radically curing the gout I am not ready to determine. There are hifto- ries of cafes of the gout, in which it is faid, that by great emotions of mind, by wounds, and by other accidents, the fymptoms have been fuddenly relieved, and never again returned ; but how far thefe accidental cures might be imi- tated by art, or would fucceed in other cafes, is at leaft extremely uncertain. 540.] The praaices proper and neceffary in the treat- ment of the gout, are to be confidered under two heads; first, As they are to be employed in the intervals of pa- roxyfms; or, secondly, As during the time of thefe. 541.] In the intervals of paroxyfms, the indications are, to prevent the return of paroxyfms, or at leaft to ren- der them lefs frequent, and more moderate. During the time of paroxyfms, the indications are, to moderate the violence, and fhortcn the duration of them as much as can be done with fafety. 542.] It has been already obferved, thatthe gout may be entirely prevented by conftant bodily exercife, and by a low diet; and I am of opinion, that this prevention may take place even in perfons who have a hereditary difpofi- tion to the difeafe. I muft add here, that, even when the difpofition has difcovered itfelf by feveral paroxyfnw of inflammatory gout, 1 am perfuaded that labour and . abftinence will abfolutely prevent any returns of it for the reft of life.* Thefe, therefore, are the means of an- fwering the firft indication to be purfued in the intervals of paroxyfms; and I muft here offer fome remarks upon the proper ufe of thefe remedies. * Several cafes are to be met with in practical authors, which confirm this Obfervation. Van Swieten relates the cafe of a prieft, who enjoyed a jich i living, ahd had been long an old and conftant fufferer in the gout ; but hap- pening at laft to be taken by the pirates of Barbary, was detained there in a ftate of flavery fot the fpace of two years, and kept conftantly at work in the galleys, with only a very fpare diet. The regimen he there underwent had this good effeft, that after he was ranfomed from his captivity, having loft his troublefome and monftrous fatnefs, he never once had a fit of the gout, though he lived feveral years af.er the event happened. • 1 OF PIPY SIC. 201 543.] Exercife, in perfons difpofed to the gout, is di- reaed to two purpofes: Que of thefe is the lengthen- ing of the tone of the extreme veffels; and the other, the guarding againft a plethoric ftate. For the former, if exercife be employed early in life, and before intem- perance has weakened the body, a very moderate degree of it will anfwer the purpofe; and for the latter, if abfti- nence be at the fame time obferved, little exercife will be neceffary. 544. j With refpea to exercife, this in general is to be obferved, that it fhould never be violent; for if violent, it it cannot be long continued, and muft always endanger the bringing on an atony in proportion to the violence of the preceding exercife; 545.] It is alfo to be obferved, that the exercife of gefta- tion though confiderable and conftant, if it be entirely with- out bodily exercife, will not anfwer the purpofe in prevent- ing the gout. For this end, therefore, the exercife muft be in fome meafure, that of the body, and muft be moderate, but at the fame time conftant and continued through life. 546.] In eveiy cafe and circumftance of the'gout in which the patient retains the ufe of his limbs, bodily ex- ercife, in the intervals of paroxyfms, will always be ufe- ful; and, in the beginning of the difeafe, when the difpo-' fition to it is not yet ftrong, cxercife may prevent a pa- roxyfm which otherwife might have come on. In more advanced ftates of the difeafe, however, when there is fome difpofition to a paroxyfm, much walking will bring it on; cither as it weakens the tone of the lower extremi- ties, or as it excites an inflammatory difpofition in them ; and it is probable, that in the fame manner ftrains or con- tufions often bring on a paroxyfm ofthe gout. 547.] Abftinence, the other part of our regimen (539 ) for preventing the gout, is of more difficult application. If an abftinence from animal food be entered upon early in hfe, while the vigour of the fvftcm is yet entire, we have no doubt of its being both'fafe and effeaual; but if the motive for this diet fhall not have occurred till the conftitution fhall have been broken by intemperarreej or by the decline of life, a low diet may then endanger the bringing on an atonic ftate. Vol, I. C c - se: "Practice 548 ] Further, if a low diet be entered upon only in the decline of life, and be at the fame time a very great change in the former manner of living, the withdrawing of an accuftomed ftimulus of the fyftem may readily throw this into an atonic ftate.* 549.] The fafety of an abftemious courfe may be great- er or lefs according to the management of it. It is ani- mal food which efpecially difpofes to the plethoric and in- flammatory ftate, and that food is to be therefore efpe- cially avoided; but, on the other hand, it is vegetable aliment of the loweft quality that is in danger of weaken- , ing the fyftem too much, by not affording fufficient nou- rifhment; and more particularly of weakening the tone of the ftomach by its acefeency. It is therefore a diet of a middle nature that is to be chofen; and milk is precifely of this kind, as containing both animal and vegetable matter. As approaching to the nature of milk, and as being a vegetable matter containing the greateft portion of nou- rifhment, the farinaceous feeds are next to be chofen, and are the food moft proper to be joined with milk. 550.] With refpea to drink, fermented liquors are ufe- ful only when they are joined with animal food, and that by their acefeency; and their ftimulus is only neceffary from cuftom. When, therefore, animal food is to be avoided, fermented liquors arc unneceffary; and, by in- creafing the acefeency of vegetables, thefe liquors may be hurtful. The ftimulus of fermented or fpirituous liquors, ' is not neceffary to the young and vigorous ; and, when much employed, impairs the tone of the fyftem. Thefe liquors, therefore, are to be avoided, except fo far as cuftom and the declining ftate of the fyftem may have rendered them neceffary. For preventing or moderating the regular gout, water is the only proper drink. ; 551.] With refpea to an abftemious courfe, it has been ^ fuppofed that an abftinence from animal food and ferment- i ed liquors, or the living upon milk and farinacea alone for the fpace of one year might be fufficient for a radical cure I of the gout; and it is poffible that, at a certain period of j • A fudden change from a full to a fpare diet was juftjy enumerated among J the occaficnai caufes of the gout in Art. 503. £■ & F P H Y S I C. 2C5 life, in certain circumftances of the conftitution, fuch x meafure might anfwer the purpofe. But this is very doubt- ful ; and it is more probable that the abftinence muft, in a great meafure, be continued, and the milk diet be perfift- ed in, for the reft of life. It is well known, that feveral perfons who had entered on an abftemious courfe, and had. been thereby delivered from the gout, have, however, upon returning to their former manner of full living, had the difeafe return upon them with as much violence as before, or in a more irregular and more dangerous form. 552.] It has been alledged, that, for preventing the- return of the gout, bloodletting, or fcarifications of the feet, frequently repeated,.and at ftated times, may be prac- tifed with advantage; but of this I have had no experience. 553.] Exercife and abftinence are the means of avoid- ing the plethoric ftate which gives the difpofition to the gout; and arc-therefore the means propofed for prevent- ing paroxyfms, or at leaft for rendering them lefs frequent, and more moderate. But many circumftances prevent the ftcadinefs ncceffary in pur filing, thefe meafures; and therefore, in fuch cafes,, unlefs great care be taken to avoid the exciting caufes, the difeafe may frequently re- turn ; and in many cafes, the preventing of paroxyfms is chiefly to be obtained by avoiding thole exciting caufes enumerated in (503.) The condua neceffary for avoid- ing them, will be fufffciently obvious to perfons acquaint- ed with die do8trincs of the Hygicinc, which I fuppofe to have been delivered in another place 554.] A due attcn:ion in avoiding thofe feveral caufes (502. 503.) will certainly prevent fits of the gout; and the taking care that the exciting caufes be never applied in a great degree, will certainly render fits more moderate when they do come on. But, upon the whole, it will ap- pear, that a ftria attention to the whole condua of lifcr is in this matter neceffary ;* and therefore, when the pre- * The phyfician has more difficulty in perfuading his patients to a proper regimen in the gout than in any other difeafe ; and.if he would gain reputa- tion, he ou^ht to pay peculiar attention to this part of pra&ice, and ufe his utmeft arc in convincing his patient of the necelfity of au abftemious diet,. and a regular conduct.. Gouty patients are generally the genuine oiTspring of jolly Bacchus, and; prefer the traniient indulgence of their jovial inclinations to the r&nfom of whole year-, of torment at the eafy price of a life of fobriety and temper- ance, until the invincible Ou- 204 PRACTICE difpofitio!! has taken place, it will be extremely difficult to avoid the difeafe. ** 555.] I am indeed firmly perfuaded, that, by obviat- ing the predifpofition, and by avoiding the exciting caufes, the gout may be entirely prevented: But as the meafures neceffary for this purpofe, will in moft cafes, be purfued with difficulty, and even with reluttance, men have been very defirous to find a medicine which might anfwer the purpofe without any reftraint on their manner of living. To gratify this defire, phyficians have propofed, and, to take advantage of it, empirics have feigned, many reme- dies, as we have already obferved. Of what nature feve- ral of thefe remedies have been, I cannot certainly fay; but, of thofe which are unknown, we conclude, from their having been only of temporary fame, and from their having foon fallen into negfea, that they have been either inert or pernicious, and therefore I make no inquiry after them ; and fhall now remark only upon one or two known remedies for the gout, which have been lately in vogue. 556.] One of thefe is what has been named in Eng- land the Portland Powder * This is not a new medicine, vinces them of their errors. They are then anxious for medical advice, and after confulting the phyfician, they are willing implicitly to obey his ftridhdt injundions. They feldom, however, then find much relief ; and remain living proofs of the truth cf the adage : --------fero medicina paratur, Cum mala per longas invalueie moras. * This medicine was fo called from one of the Dukes of Portland being cured by it, cf an hereditary and very inveterate gout. It confifts of equal parts of the follow ing bitter aromatics : viz. Rad. ariftolochiaerotundx, Rad. gentianae, Summitat. chamedryos, Summitat. chamzepityos, Summitat. cen- taur, min. A drachm of this powder is ordered to be taken, in any convenient vehicle, as a little wine, broth, tea, &c. in a morning, fafting, the patient tailing nothing for an hear and an half after it; it muft be ufed in this dofe for three months without the leaft interruption : Forty-five grains are to be taken daily in the fame manner, for the fucceeding three months: half a drachm every day, for the next fix months; and half a drachm every other day, during the fecond year. It it. fometimes two years complete before any change be produced, but the patient muft not therefore abandon the medi- cine, but continue its ufe. Thefe aromatic bitters have been long in ufe as remedies for the gout. We find Galen prefcribing in this difeafe the feeds and tops cf wild rue, birth-wort, lefler centaury, gentian, &.c. either fingiy, or mixed in certain proportions. Trallian defcribes fimilar antidotes, which he fays, muft be continued for a great length of time, viz. iix or feven months, or even ffcr a year and upwards. The tetra-pharmacon of Aetius, compofed cf gentian, birth-wort, bay-berries, and myrrh, is a rimilar remedy, and is alfo directed to be ufed for a great length of time. Carlius Aurelianus likewife mentions the bitters to be long ufed in the gout, and he gives them the appofite epi- thet of annalia. The Diatefferon, which has not been long throw ;i out of OF PHYSIC. 205 but is mentioned by Galen-, and, with fome little varia- tion in- its compofition, has been mentioned by the writers of almoft every age fince that time. It appears to have been at times in fafhion, and to have again fallen into neglect; and I think that this laft has been owing to its having been found to be, in many inftances, pernicious. In every inftance which I have known of its exhibition for the fengih of time prefcribed, the perfons who had taken it were indeed afterwards free from any inflamma- tory affection of the joints; but they were affected with many fymptoms of the atonic gout; and all, foon after finifhing their courfe of the medicine, have been attacked with apoplexy, afthma, or dropfy, which proved fatal. 557.J Another remedy which has had the appearance of preventing the gout, is an alkali in various forms, fuch as the fixed alkali both mild and cauftic, lime water, foap and abforbent earths. Since it became common to' exhi- bit thefe medicines in nephritic and calculous cafes, it has often happened that they were given to thofe who were at the fame time fubjea to the gout; and it has been obferv ed, that under the ufe of thefe medicines, gouty perfons have been longer free from the fits of their difeafe.* That, Z &kh£ " ftiU retahied " f°me °f thC h^ P^macopcias, is of rwLUf\ 'f^^ medi.cines h*s doubtlefs in many cafes completed cured the gout; but m many cafes, even in thofe that have been cured K? eales have lupervened.

As the preventing the gout depends very much on fupporting the tone of the ftomach, and avtfjding indigeftion; fo coitivenefs, by occafioning this, is very hurtful to gouty perfons. It is therefore ne- ceffary for fuch perfons to prevent or remove coftivenefs, and by a laxative medicine, when needful; but it is at the fame time proper, that the medicine employed fhould be fuch as may keep the belly regular, without much purging. Aloetics, rhubarb, magnefia alba, or flowers of fulphur, may be employed, as the one or the other may happen to be beft fuited to particular perfons.* of thofe readers who are unacquainted with the procefs, I fliall give an ab« ftraa of it. Difiblve three ounces, Troy weight, of good fait of' Tartar in a gallon and a half of rain water, or good foft fpring water ; fibre the folution, and put as much of it into the middle glafs of Parker's machine as will completely fill the veffel, referving the remainder for a fubfequent making. The effer- vefcing materials muft then be put into the lower veflel, and a gentle ftream of fixed airmuftbe made to pafs through the liquor, till it taftes evidently acidu- lous, which will probably require forty-eight or fixty hours, or infummer more. The method of managing the effervefcence is of confiderable confequence: for, if it is too violent at iirft, much air efcapes through the veffels without effect. Afcertain, by previous experiment, how much of the vitriolic acid,, which you have procured, for it is of very different ftrengths in the fhops, will faturate a drachm of the chalk. Put four ounces of dry powdered chalk into the lower veffel, and (hake it to one fide : under that fide put a wedge, fo as to raife it above an inch and an half from the table. With a long fun- nel, which reaches to the bottom of the veffel, pour in the quantity of vit- riolic acid neceffary for the faturation, which will run down to the other fide of the veffel, and not come into contarl with the chalk: through the fame funnel, pour very (lowly as much water as will be fufficient to cover about a fourth part of the chalk as it then lies. The veffel being gently fhaken occa- fionally, the effervefcence will go on very fiowly,. and the alkaline liqur.r will be fooner and more effedually faturated, than if the effervefcence had been too violent. If the materials are not fufficient for giving an acidulous taile to the liquor, the lower veffel muft be wafhed, and frefh chalk and acid again. put into it. The dofe of this water is half a pint about noon, and another in the even- ing. In urgent cafes half a pint has been given morning, noon, and night, for a confiderable time together, without difagreeing with the ftomach, or injuring the appetite or general health of the patient. If it proves flatulent, a tea-fpoonful or two, but not more, of fpirituous cinnamon water may be taken in each dofe. If it inflames or too violently irritates the urinary paffages, five or ten, or in urgent cafes, twenty drops of laudanum mav be taken with each dofe of the'water. * The following formula may b; ufed in particular cafco : 0 F P H Y S I C. 207 559-1 Thefc ar^ the feveral meafures (from 541. to 558.) to be purfued in the intervals of the paroxyfms; and we are next to mention the meafures proper durino- the time of them. 560.] As during the times of paroxyfms the body is in a fevenfh ftate, no irritation fhould then be added to it; and ever)- part, therefore, of the antiphlogiftic regimen', (130. to 133.) except the application of cold, ought to be ftriaiy obferved. Another exception to the general rule mav occur when the tone of the ftomach is weak, and when the patient has been before much accuftomed to the ufe of ftron^ drink • for it then may be allowable, and even neceffary,°to give feme animal food, and a little wine.* 561.] That no irritation is to be added to the fyftem during the paroxyfms of gout, except in the cafes men- tioned, is entirely agreed upon among phyficians: But it is a more difficult matter to determine whether, during the time of paroxyfms, any meafures may be purfued to mo- R.

Dr. Sydenham has given it as his opinion, that the more vio- lent the inflammation and pain, the paroxyfms will be the fhorter, as well as the interval between the prefent and next paroxyfm longer; and, if this opinion be admitted as juft, it will forbid the ufe of any remedies which might moderate the inflammation; which is, to a certain degree, undoubtedly neceffary for the health of the body. On the other hand, acute pain preffes for relief; and, although a certain degree of inflammation may feem abfolutely ne- ceffary, it is not certain but that a moderate degree of it may anfwer the purpofe : And it is even probable, that, in many cafes, the violence of inflammation may weaken the tone of the parts, and thereby invite a return of pa- roxyfms. It feems to me to be in this way, that, as the difeafe advances, the paroxyfms become more frequent. 562.] From thefe laft confiderations, it feems probable, that, during the time of paroxyfms, fome meafures may be taken to moderate the violence of the inflammation and pain; and particularly, that in firft paroxyfms, and in the young and vigorous, blood-letting at the arm may be praaifed with advantage. But I am perfuaded, that this praaice cannot be repeated often with fafety ; becaufe blood-letting not only weakens the tone of the fyftem, but may alfo contribute to produce plethora. I believe, how- ever, that bleeding by leeches on the foot, and upon the inflamed part, may be praaifed, and repeated with greater fafety ; and I have known inftances of its having been prac- tifed with fafety, to moderate and fhorten paroxyfms , but how far it may be carried, we have not had experience enough to determine. 563.] Befides blood-letting, and the antiphlogiftic re- gimen, it has been propofed to employ remedies for mo- derating the inflammatory fpafm of the part affeaed, fuch as warm bathing and emollient poultices,- Thefe have fometimes been employed with advantage and fafety ; but at other times, have been found to give occafion to a re- troceffion of the gout.* __ * On this account thefe topic?l remedies ought to be ufed with great oau" tion : thejiemporary relief which they afford, by procuring an intermiffion of the pain, is agreeable to the patient, but it is frequently the occafion of an cxac erb^tion of all the fymptoms. OF PHYSIC. 209 564.] Bliftering is a very effeaual means of relieving and difcuffing a paroxyfm of the gout; but has alfo fre- quently had the effea of rendering it retrocedent.* 565.] The flinging with nettles I confider as analogous to bliftering; and I think it probable that it would be at- tended with the fame danger. 566.] The burning with moxa,t or other fubftances, I confider as a remedy of the fame kind. I have had indeed no evidence of this proving hurtful; but neither have I had any proper evidence of its having proved a radical cure. 567.] Camphire, and fome aromatic oils, have the power of allaying the pain, and of removing the inflam- mation from the part affeaed; but thefe remedies com- monly make the inflammation only fhift from one part to another, and therefore with the hazard of its falling upon a part where it may be more dangerous: and they have fometimes rendered the gout retrocedent. 568.] From thefe reffeaions (563. et feq.) it will ap- pear, that fome danger muft attend every external appli- cation to the parts affeaed during a paroxyfm; and that! therefore the common practice of committing the perfon to patience and flannel alone, is eftablifhed upon the bell foundation. 569.] Opiates give the moft certain relief from pain; but, when given in the beginning of gouty paroxyfms, occafion thefe to return with greater violence. When, * This is a very dangerous pra&ice. Blifters are however extremely ufe- ful, in bringing back the retrocedent gout to the part originally affe&ed; but, the violent degree of pain that accompanies the gout, when brought to a part already irritated by the blifters, frequently prevents a patient who has t.nce differed it, from allowing it a fecond time. It is, however, fo impor- tant and neceffary a practice, that it ought not to be omitted. As foon as the gout has been brought back to its original place, the blifters muft be immedi- ately removed, a piece of foft linen dipped in frefh oil, applied to the part, and the whole well wrapt up in foft flannel: a moderate degree of heat muft be preferved in the flannel, and the patient muft be encouraged to bear withi patience the violent pain which he fuffers. f Moxa is a foft Januginous fubftance prepared in Japan, from the young leaves of a fpecies of Artemifia, by beating them when thoroughly dried, and rubbing them between the ringers till nothing but the fineft fibres remairi. A little cone of this cottony fubftance is laid upon the Ik in, which is pre- viously moiftened to prevent the cone from hiding off: Fire is fet to the apex of the cdrie, and it is fuffered to burn till it extinguilhes itfelf. A fmall ef- char is produced and the ulcer either healed or kept open as occafion requires.

Cold bathing alfo may anfwer the purpofe, and may be eafily employed, if it appear to be powerful in ftimulating the fyftem, and be not applied when the extre- mities are threatened with any pain.t For fupporting the tone of the fyftem in general, when threatened with atonic gout, fome animal fopd+ ought to * The beft form for exhibiting opium in thefe cafes, is the Confeclio Opi- ata of the London Pharmacopoeia, or the ElecTarium Thebaicum of the Edinburgh. The dofe of the former is half a drachm, but of the latter a drachm and an half. As opiates ought never to be adminiftercd where the inflammation is vio- lent, but only in fuch cafes as are attended with little or no inflammation, thefe warm opiates cannot be improper. If however the praclitioner fliould think either of the above formula too hot, he can have recourfe to the T::;c- tura Thebaica. t Cold bathing is a doubtful remedy, and ought to be ufed with caution. If it does not prove a tonic, it ought to be abandoned; and we know by ex- perience that it frequently debilitates.

In the fame cafe, fome wine* alfo may be neceffary ; but it fhould be in moderate quantity, and of the leaft accfeent kinds; and, if every kind of wine fliall be found to increafe the acidity of the ftomach, ardent fpi- rits and water muft be employed.t 576.] For ftrengthening the ftomach, bitters and the Peruvian bark may be employed; but care muft be taken that they be not conftantly employed for any great length of time. Compare 556. The moft effectual medicine for ftrengthening the ftomach is iron, which may be employed under various preparations; but, to me, the beft appears to be the ruft in fine powder, which may be given in very large dofes.J For fupporting the tone of the ftomach, aromatics may be employed ; but fliould be ufed with caution, as the fre- , quent and large ufe of them may have an oppofite effea ; and they fhould therefore be given only in compliance with former habits, or for palliating prefent fymptoms.

No drink is perhaps more prejudicial for gouty patients, than what is called rich punch, viz. with a large quantity of fugar and lemon, efpecially when taken warm. ^ The dofe muft be very fmall at firft, not exceeding four or five grains in the day ; the dofes may be daily increafed two grains, till we arrive at ten or twelve, and after two or three days, ten grains may be given twice a day. Aromatics always make it fit eafier on the ftomach than it would do if takca alone ; the moft convenient form therefore is the following: R. Rubigv Martis, gr. 10. Confeci. Card. 3 lb* Syr.

In perfons liable to the atonic gout, ilfues may be eftablifhed in the extremities, as, in fome meafure, a fupplement to the difeafe. '■679'] A fecoiid cafe ofthe irregular gout, is that which I have named the Retrocedent. When this affeas the ftomach and inteftines, relief is to be inftantly attempted by the free ufe of ftrong wines, joined with aromatics, and given warm ; or if thefe fhall not prove powerful enough, ardent fpirits muft be employed, and are to be given in a large dofe. In moderate attacks, ardent fpirit impreg- nated with garlic, or with afafcetida, may be employed; or, even without the ardent fpirits, a folution of afafcetida with the volatile alkali may anfwer the purpofe. Opiates are often an effeaual remedy, and may be joined with aromatics, as in the Efeauarium Thebaicum * or they may be ufefully joined with volatile alkali and camphire.t Mufk has likewife proved ufeful in this difeafe.

BOOK III. Of Exanthemata, or Eruptive Fevers. 584.] X HE difeafes comprehended under this title, which make the third Order of Pyrexiae in our Nofology, are in general fuch as do not arife but upon occafion of a fpecific contagion applied, which firft produces fever, and afterwards an eruption upon the furface of the body ; and which difeafes, for the moft part, affea perfons but once in the courfe of their lives. 585.] Whether the charaaer ofthe Order may be thus limited, or if the Order may be allowed to comprehend al- fo the eruptive fevers produced by a matter generated in the body itfelf, and likewife thofe cafes of eruption which do not depend upon contagion, or upon a matter generat- ed before the fever, but upon a matter generated in the courfe of the fever, I am not ready to determine. Of the difeafes enumerated by the Nofologifts as Exanthema- ta, there are certainly three different kinds, which may be diftinguifhed by the circumftances mentioned in this and the preceding paragraph. Of the firft kind are the Small Pox, the Chicken Pox, the Meafles, the Scarlet Fever, and the Plague. Of the fecond kind feems to be the Eryfipelas; and of the third kind I judge the Miliaria and Petechia to be. But as I am no't fufficiently con- fident in the faas which fliould fupport thefe diftinaions, or which would enable us to apply them in all cafes; I go on in this book to treat of almoft all the exanthemata enu- merated by preceding Nofologifts, with only fome differ- ence in the arrangement from what it was in my former editions. CHAP. I. £Dftfje§maUP)r* 586.] 1 HE fmall pox is a difeafe arifing from a con- tagion of a fpecific nature, which firft produces a fever; O F PHY SIC. "215 and on the third or fourth day thereof, produces an erup- tion of fmall red pimples. Thefe are afterwards formed into puftulcs, containing a matter, which, in the courfe of eight days from the time of the eruption, is changed into pus. After this, the matter dries, and falls off in crufts. 587.] This i.> a general idea ofthe difeafe; but there are two particular forms or varieties of it, well known un- der the appellation!* of the Distinct and Confluent, which requires to be fpccially defcribcd. 588.J In the former, or the diftina finall pox, the eruptive fever is moderate, and appears to be evidently of the inflammatory kind, or what we name a Synocha. It generally comes on about mid-day, with fome fymptoms of a cold ftage, and commonly with a confiderable lan- guor and drowfinefs. A hot ftage is-foon formed, and becomes more confiderable on the fecond and third days. During this courfe, children are liable to frequent ftart- ings for their {lumbers; and adults, if they are kept abed, are difpofed to much fweating. On the third day, chil- dren are fometimes affeaed with one or two epileptic fits. Towards the end of the third day, the eruption common- ly appears, and gradually increafes during the fourth; appearing firft upon the face, "and fucceflively on the in- ferior parts, fo as to be completed over the whole body on the fifth day. From the third day the fever abates; and againft the fifth it entirely ceafes. The eruption appears firft in fmall red fpots, hardly eminent, but by degrees riling into pim- ples. Thefe are generally upon the face in fmall num- ber ; but even when more numerous, they are feparate and diftina from one another. On the fifth or fixth day, a finall vcficle, containing an almoft colourlefs or whey- coloured fluid, appears upon the top of each pimple. For two days, thefe vcficles increafes in breadth only, and there is a fmall hollow pit in their middle; fo that it is on- ly againft the eighth day that they are raifed into fpheroidi- cal puftulcs. Thefe vcficles or puftulcs, from their firft formation, continue to be furrounded with an exaaiy circular inflam- ed margin, which, when the puftules are numerous, diffu- fes fome inflammation over the neighbouring fkin, fo as to give fomewhat of a damafk rofe-colour to the fpaces be- 1 5 IS |£ PRACTICE tween the pufiufes. As the puftulcs increafe in fize, if they be numerous on the face, againft the eighth day the whole of the face becomes confiderably fwelled ; and, in particular, the eye-lids are fo much fwelled as entirely to ftiut the eyes. As the difeafe thus proceeds, the matter in the puftulcs becomes by de'grees more opaque and white, and at length of a yellowifh colour. On the eleventh day, the fwelling of the face is abated, and the puftulcs feem quite full. On the top of each a darker fpot appeafs; and at this place the puftule, on the eleventh day, or foon after, is fpon- taneoufly broken, and a portion of the matter oozes out; in confequence of which, the puftule is fhrivelled, and fubfides ; while the matter oozing out dries, and forms a cruft upon its furface. Sometimes a little only of the matter oozes out; and what remains in the puftule be- comes thick and even hard. After fome days, both the crufts and the hardened puftulcs fall off, leaving the fkin which they covered of a brown red colour; and it is only after many days that the fkin. in thefe places refumes its natural colour. In fome cafes, where the matter of.the puftulcs has been more liquid, the crufts formed by it are later in falling off, and the part they covered fuffers fome defquamation, which leaves in it a fmall pit or hollow. This is the courfe of things on the face; and fucceflivcly, the puftules on the reft of the body take the fame. The matter of the puftules, on the arms and hands, is frequently abforbed; fo that, at the height ofthe difeafe, thefe puftules appear empty veficles. On the tenth and eleventh days, as the fwelling of the face fubfides, a fwelling arifes in the hands and feet; but which, again, fubfides, as the puftules come to maturity. When the puftules on the face are numerous, fome de- gree of pyrexia appears on the tenth and eleventh days, but difappears again after the puftules are fully ripened; or perhaps remains in a very flight degree till the puftules on the feet have finifhed their courfe. It is feldom that in the diftina fmall-pox the fever continues longer. When the puftules on the face are numerous, fome uneafinefs in the throat, with ahoarfenefs of the voice comes on upon the fixth or feventh day, and a thin liquid is pour- ed out from the mouth. Thefe fymptoms increafe with OF PHYSIC. $1* the fwelling ofthe face ; and the liquids ofthe mouth and throat becoming thicker, are more difficultly thrown out. There, is, at the fame time, fome difficulty of fwallowing; fo that liquids taken in to be fwallowed are frequently re- jected, or thrown out by the note. But all thefe affections of the fauces abate as the fwelling ofthe face fubfides.* 589.] In the Other form of fmall-pox, or what is called the Confluent, the courfe of the difeafe is, in general, the fame with that we have defcribed; but the fymptoms of every ftage are more violent, and feveral of the circum- ftances are different. In particular, the eruptive fever is more violent. The pulfe is more frequent and more contraaed, approaching to that ftate of pulfe which is found in the typhus. The coma is mare confiderable, and there is frequently a de- lirium. Vomiting, alfo, is a common fymptom, efpeci- ally at the coming on of the difeafe. In very young in- fants, epileptic fits are fometimes frequent on the firft days, of the difeafe, and fometimes proves fatal before any erup- tion appears • or they ufher in a very confluent and putrid fmall pox. 590.] The eruption appears more early on the third day, and it is frequently preceded or accompanied with an eryfipelatous afflorefcence. Sometimes the eruption appears in clufters, like that of the meafies. When the eruption is completed, the pimples are always more nu- merous upon the face, at the fame time fmaller and lefs eminent. After the eruption, the fever fuffers fome re- miffiort, but never goes off entirely; and, after the fifth or fixth day, it again increafes, and continues confiderable through the remaining courfe of the difeafe. The vcficles formed on the tops of the pimples appear fooner; and while they increafe in breadth, do not retain a circular, but arc every way of an irregular figure. Many of them run into one another, infomuch that° very often * The difcharge of faliva is always falutarv, and ought to Be moderately encourajre.1. It is probably owing to the morbific matter attacking the fall. vary glands, and through them making its exit out of the body. A I the affeftions of the fauces, and the falivation, gradually abate as the fwe lm^ot the face iubf.de. ; but if thefe iymptoms difappear suddenly, or are not lucoied.d by a fwelling of the extremities, danger is to be apprehended rim remark,, fojely the refult of experience, and the ttpuStion ofS l-.-ems to be involved 111 conhderable difficulty. r Vol. I. E K Y 31* PRACTICE the face is covered rather with one veficlc than with a num- ber of puftules. The veficles, fo far as they are any-wife feparated, do not arife to a fpheroidical form, but remain flat, and fometimes the whole ofthe face is of an even fur- face. When the puftules are in any meafure feparated, their circumference is not bounded with an inflamed mar- gin, and the part of the fkin that is free from puftules is commonly pale and flaccid. The liquor that is in the puftules changes from a clear to an opaque appearance, and becomes whitifh or brown- ifh, but never acquires the yellow colour and thick con- iiftence that appear in the diftina fmall-pox. 591.3 The fwelling ofthe face which attends the diftina fmall-pox, when they are numerous, and almoft then only, always attends the confluent, comes on more early, and arifes..to a greater degree; but abates on the tenth day, and on the eleventh ftill more. At this time the puftules or veficles break, and lhrivelling pour out a liquor that is formed into brown-or black crufts, which do not fall off for many days after. Thofe of the face, in falling off, leave the parts they cover fubjea to a defquamation, which pretty certainly produce .pittings. On the other parts of the body, the puftules of the con- fluent fmall-pox are more diftina than upon the face, but never acquire the fame maturity -and conftftence of pus'as in the properly diftina kind. The falivation which only fometimes attends the diftinct {mall-pox, very conftantly attends the confluent: and both the falivation and the affeaion of the fauces above- mentioned are, efpecially in adults, in a higher degree. In infants, a diarrhoea comes frequently in place of the fali- vation. In the confluent fmall-pox, there is often a confiderable putrefcency of the fluids, as appears from petechia?, from ferous veficles, under which the fkin fhows a difpofition to gangrene, and from bloody urine or other haemorhargy, all which fymptoms frequently accompany this elifeafe. In the confluent fmall-pox, the fever, which had only fuffered a remiflion from the time of eruption to that of maturation, is often, at or immediately after this pteriod, renewed with confiderable violence. This is what has OF PHYSIC. 21* been called the Secondary Fever; and is, in different ca- fes, of various duration and event. 592] We have thus endeavoured to defcribe the vari- ous circumftances of the fmall-pox ; and from the differ- ence of thefe circumftances, the event of the difeafe may be determined. The whole of the prognofis may be near- ly comprifed in the following propofitions. The more exaaiy the difeafe retains the form of the diftina kind, it is the fafer; and the more completely the difeafe takes the form of the confluent kind, it is the more dangerous. It is only when the diftina kind fhows a great number of puftulcs on the face, or otherwife, by fever or putref- cency, approaches to the circumftances of the confluent, that it is attended with any danger. In the confluent fmall-pox there is always danger ; and this is always more confiderable and certain, according as the fever is more violent and permanent, and efpecially as the marks and fymptoms of putrefcency are more evident. When the putrid difpofition is very great, the difeafe fometimes proves fatal before the eighth day; but itvmoft cafes it is on the eleventh that death happens, and fome- times it is put off till the fourteenth or feventeenih day. Though the fmall-pox fliould not be immediately fatal, the more violent kinds arc often followed by a morbid ftate ofthe body, of various kind and event. Thefe con- fequences, as I judge, may be imputed fometimes to an acrid matter produced by the preceding difeafe, and de- pofited indifferent parts; and fometimes to an inflamma- tory diathefis produced, and determined to particular parts of the body. 593.] It is, I think, agreed among praaitioners, that, in the different cafes of fmall-pox, the difference chiefly depends upon the appearance of diftina or confluent'; and, from the above defcription of thefe kinds, it will ap- pear, that they chiefly differ in the period ofthe eruption, in the number of puftules produced, in the form of the puftules, in the ftate of the matter contained in them, in the continuance of the fever, and laftly in the danger of the difeafe. 594-] Upon inquiring into the caufes of thefe differen- ces, we might readily fufpea, that they depended upon a 220 PRACTICE' difference of the contagion producing the difeafe. This, however, is not probable: for there are innumerable in- ftances of the contagion, arifing from a perfon labouring under the fmall-pox of the diftina kind, producing ths confluent; and on the contrary. Since the practice of inoculation became frequent, we have known the fame variolous matter produce in one perfon the. diftina, and in another the confluent fmall-pox. It is therefore high- ly probable, that the difference of the fmall-pox does not depend upon any difference of the contagion, but upon fome difference in the ftate of the perfon to whom it j$ applied, or in the ftate of certain circumftances concur- ring with the application of the contagion. 595.] To find out wherein the difference in the ftate of the perfons to whom the contagion ofthe fmall-pox is ap- plied confifts, I obferve, that the difference between the diftina and confluent fmall-pox confifts efpecially in the number of puftules produced; which, in the diftina, are generally few, in the confluent, always' many. If, there- fore, we fhall be able to difcover what, in the ftate of dif- ferent perfons, can give occafion to more or fewer puf- tules, we fhall probably be able to account for all the other differences of the diftina and confluent fmall-pox, 596.] It is evident, that the contagion of the fmall-pox is a ferment with refpea to the human fluids, and affimi- lates a great part of them to its own nature ;* and it is pro- bable, that the quandty thus affimilated, is, in proportion to the bulk of their feveral bodies, nearly the fame in dif: ferent perfons. This quantity paffes again out of the bo- dy, partly by infenfible perfpiration, and partly by being depofited in puftules; but if the quantities generated be nearly equal, the quantities pafting out of the body by the two ways mentioned are very unequal in different perfons; and, therefore, if we can explain the caufes which deter- mine more to pafs by the one way than by the other, we * This opinion is moft probably true, but it is by no means (as the author fays,) evident. His reafoning however, is ingenious, and deferves atten- tion. The expulfion, or rather evacuation ofthe morbific matter is admitted as a cure ofthe difeafe, and the difference of the difeafe to the different manner in which this evacuation is made: But the author has not prowl either of the premiffes he has advanced, viz. that the quantity of hum** fluids which the ferment affimilates, is nearly the fame in different perfons', nor that any part of the morbihc matter, or the morbid affimilated fluids pafs off by perfpiration. OF PHYSIC. ?2J may thereby difcover the caufes which give occafion to more puftules in one perfon than in another. 597.] The caufes which determine more of the variol- ous matter to pafs by perfpiration, or to form puftules, are probably certain circumftances of the fkin, that determine more or lefs of the variolous matter to flick in it, or to pals freely through it. 598.] The circumftance of the ikin, which feems to determine the variolous matter to ftick in it, is a certain ftate of inflammation depending, much upon the heat of it. Thus we have many inftances of parts ofthe body, from being more heated, having a grc&tcr number of puf- tules than other parts. In the prefent praaice of inocu- lation, in which few puftules are produced, much feems to be owing to the care that is taken to keep the fkin cool. Parts covered with platters, efpecially with thofe of a fti- mulant kind, have more puftules than other parts. Fur* ther, certain circum Stances, fuch as adult age, full living, determining to a'phlogiftic diathefis, feem to produce a .greater: number of puftules ; while the contrary circum- ftances have contrary effects. 599 ] It is therefore probable, that an inflammatory ftate of the whole fyftem, and more particular!)' of the fkin, gives occafion to a greater number of puftules : and the caufes of this may likewife produce moft ofthe other circumftances ofthe confluent fmalkpox; fuch as the pe- riod of eruption; the continuance of the fever ; the effu- fion of a more putrefcent matter, and lefs fit to he convert- ed into pus ; and, what arifes from thence, the form and other circumftances of the puftules. 600.] Having thus attempted to account for the chief difference which occurs in the ftate of the fmall-pox, we fliall now try the truth of our doarine, by its application to praaice. 601.] In confidering the praaice, we view it firft, in general, as fuited to render the difeafe more generally be*- nign and fafe, and this by the praaice of inoculation. 602.] It is not neceffary here to defcribe the operation of inoculating; and what we name the pTaaice of inocula- tion, comprehends all the feveral meafures which precede or follow that operation, and are fuppofed to produce its falutary effeas. , 222 PRACTICE Thefe meafures are chiefly the following. 1. The choofing for the fubjea of inoculation perfons otherwife free from difeafe, and not liable, from their age or other circumftances, to any incidental difeafe. 2. The choofing a perfon at the time of life moft favour- able to a mild difeafe. 3. The choofing for the praaice a feafon the moft con- ducive to the mildnefs ofthe difeafe. 4. The preparing the perfon to be inoculated, by abfti- nence from animal food for fome time before inoculation. 5. The preparing the perfon by courfes of mercurial and antimonial medicines.* 6. The taking care, at the time of inoculation, to avoid cold, intemperance, fear, or other circumftances which might aggravate the future difeafe. 7. After thefe preparations and precautions, the choof- ing a fit matter to be employed in inoculation, by taking it from a perfon of a found conftitution, and free from any difeafe or fufpicion of it; by taking it from a perfon who has had the fmall pox of the moft benign kind; and, laftly, by taking tile matter from fuch perfons, as foon as it has appeared in the puftules, cither in the part inoculated, or on other parts of the body. 8. The introducing, by inoculation, but a fmall portioit of the contagious matter. 9. After inoculation, the continuing the vegetable diet, as well as the employment of mercurial and antimonial medicines ; and, at the fame time, frequently employing purgatives. 10. Both before and after inoculation, taking care to avoid external heat, either from the fun, artificial fires, warm chambers, much clothing, or being much in bed; and, on the contrary, expofing the perfon to a free and cool air. 11. Upon the appearance of the eruptive fever, the ren- dering that moderate by the employment of purgatives; by the ufe of cooling and antifeptic acids; and efpecially by expofing the perfon frequently to a cool and even a cold air, at the fame time giving freely of cold drink. 12. After the eruption, the continuing the application * Comgarethis paragraph with what follows in article 608. OF PHYSIC. .223 of cold air, and the ufe of purgatives, during the courfe of the difeafe, till the puftules are fully ripened. 603.] Thefe are the meafures propofed and praaifed in the latelt and moft improved ftate of inoculation ; and the advantages obtained by the whole of the praaice, or at leaft by moft of the meafures above mentioned, are now afcer- tained by a long experience to amount to this, That, in iiinety nine cafes of the hundred, inoculation gives a dif- tina fmall pox only, and that alfo very generally of the mildeft form ; but it will ftill be ufeful, for the proper condua of inoculation, to confider the importance and utility of the feveral meafures above mentioned, that we may thereby more exaaiy determine upon what the advan- tages of inoculation more certainly depend. 604.] As the common infc£tion may often feize perfons labouring under another difeafe, which may render the fmall pox more violent, it is obvious that inoculatirvmuft have a great advantage, by avoiding fuch concurrence. But as the avoiding fuch concurrence may often, in the mean while, leave perfons expofed to the common infec- tion, it merits inquiry, whether every difeafed ftate fhould rcftrain from the praaice of inoculation, or what are the particular difeafes that fhould do fo. This is not yet fuf- ficiently afcertained by obfervation; and we have fre- quently remarked, that the fmall pox have often occurred with a difeafed ftate of the body, without being thereby rendered more violent. In particular, we have obferved, that a ferophulous habit, or even the * Opiates, in all inflammatory cafes, ought to be cautioufly ufed. The danger arifing from them is confiderably obviated, by ufing only the gummy part of the opium, and therefore the watery folution of opium, ib in thefe cafes preferable to any other form. The Syrupus papaveris albi, is an opiate peculiarly adapted to this difeafe; the dofe of it is immaterial, provided we do not exceed four ounces in the foftr and twenty hours ; a table-fpoonful may be taken when the cough is iroublefome, and may be repeated every two or three hours according to the urgency of the fymptoms. t The complaints wl.ich the meafies leave are chiefly pneumonic. The cough is the moft troubiefome fymptom, and to relieve the patient from it, not only bleeding and purging muft be ufed, but expectorants ought alfo tobe adminiftered. The Lac Ammoniacum, formerly mentioned, has often prcv- eJ beneficial. On the fuppofition, that the cough and pneumonic affeclion remaining after the meafies are owing to a peculiar acrimony, fome pra&itiouers have recom- mended alteratives and demulcents : Experience, however, has found little advantage from their ufe. I once faw a body opened, that had died 32 dajs after the eruption ; the internal furface of the hronchise was covered with fmall furfuraceous fcales, fomewhat like thofe that appear on the fkin when the eruption goes off. Hence I have been induced to fuppofe, that expecto- rants are the belt remedies in thefe cafes, and indeed, experience cc minus the practice. Bleeding and purging are only to be occafionally ufed, in order to prevent the inflammation. The beft method of avoiding the ill confcquen- ces that follow the difeafe, is a free ufe of demulcent drinks during the eiup- OF PHYSIC. 237 649.] From our late experience ofthe benefit of cold air in the eruptive fever of the fmall-pox, fome phyficians have been of opinion, that the practice might be transfer- red to the mealies; but we have not yet had trials fuffi- cient to a {certain this. There is no doubt that external heat may be very hurtful in the meafies, as in moft other inflammatory difeafes; and therefore the body ought to be kept in a moderate tem- perature during the whole courfe of the meafies; but how far, at any period of the difeafe, cold air may be applied with fafety, we are yet uncertain. Analogy, though fo often the refource of phyficians, is, in geneial, fallacious; and further, though the analogy with the fmall-pox lead to » the application of cold air during the eruptive fever ofthe meailes, the analogy with catarrh feems to be againft the practice. After the eruption had appeared upon the fkin, we have had many inftances of cold air making it difap- pear, and thereby producing much diforder in the fyftem ; ' and have alfo had frequent examples of fuch diforder be- ing removed by rcftoring the heat ofthe body, and there- by again bringing forth the eruption.* CHAP. IV. SDft&e <®tailzt Sfztob 650.] J.T may be doubted if the fearlct fever be a difeafe fpecifically different from the cynanche maligna above def- cribed. The latter is almoft always attended with a fcar- fet eruption ; and, in all the inftances I have feen of what may be called the fearlet fever, the difeafe, in almoft eve- ry perfon affeaed, has been attended with an ulcerous fore throat. 651. This view ofthe matter may create fome doubt; tion, and of expectorants immediately after it. The decoaum hordei compo- fitum, ofthe London Pharmacopoeia is peculiarly adapted to thefe cafes, but it is much improved by adding half an ounce of Orrice root, when it is nearly boiled enough ; if the Orrice be added too foon, the efficacious part of it eva- porates. The Lac Ammoniacum above mentioned, is averv pr~j;;i «::;;i.mig- rant, but if it fliould prove too naufeous, through ufe, and be loathed by the patient, recourfe may be had tb the weak folution of the Tartar Einetic, fo oiten mentioned in thefe notes. * Though the application of cold air be dangerous, yet ventilation is of confiderable ufe in the meafies; as is alio a frequent change of linen, and clcanhnefs. 238 PRACTICE bin I am ftill of opinion, that there is a fcarlet fever which is a difeafe fpecifically different from the Cynanche Maligna. Dr. Sydenham has defcibed a fcarlet fever, which he had feen prevailing as an epidemic, with all the circumftances of the fever and eruption, without its being accompanied with any affeaion of the throat; at leaft he does not take notice of any fuch affeaion, which fuch an accurate ob- ferver could not fail to have done, if any fuch fymptom, as we have commonly feen making a principal part of the dif- eafe, had attended thofe cafes which he had obferved. Se- veral other writers have defcribed the fcarlet fever in the fame manner, and I know phyficians who have feen the dif- eafe in that form ; fo that there can be no doubt of there being a fcarlet fever not neceffarily conneaed with an ulce^ rous fore throat, and therefore a difeafe different from the Cynanche Maligna. 652.] But, further, although in all the inftances of fcar- let fever which I have feen, (and in the courfe of forty years I have feen it fix or feven times prevailing as an epedemic in Scotland) the difeafe, in almoft all the perfons affe6ted, was attended with an ulcerous fore throat, or was what Sau- vages names the Scarlatina Anginofa; and although, in fome inftances the ulcers of the throat were of a putrid and gangrenous kind, and at the fame time the difeafe in all its fymptoms refembled very exaaiy the Cynanche Ma- ligna ; yet I am ftill perfuaded, that not only the Scarla- tina of Sydenham, but that even the Scarlatina Anginofa of Sauvages, is a different difeafe from the Cynanche Maligna ; and I have formed this opinion from the follow- ing confiderations. 653.] 1st, There is a fcarletfever entirely free from any affeaion ofthe throat, which fometimes prevails as an epi- demic; and therefore there is a fpecific contagion produc- ing a fcarlet eruption without any determination to the throat. 2dly, The Scarlatina, which, from its matter being ge- nerally determined to the throat, may be properly termed Anginofa, has, in many cafes of the fame epidemic, been without any affeaion ofthe throat; and therefore the con- tagion may be fuppofed to be more efpecially determined to produce the eruption only. %dly, Though in all the epidemics that I could alledge to be thofe of the Scarlatina Anginofa, there have been OF PHYSIC. 239 fome cafes, which, in the nature of the ulcers, and in other circumftances, exaaiy refembled the cafes of the Cy- nanche Maligna; yet I have as conftantly remarked, that thefe cafes have not been above one or two in a hundred, while the reft have all of them been with ulcers of a be- nign kind, and with circumftances hereafter to be defcrib- ed, fomewhat different from thofe of the cynanche ma- ligna. qthly, On the other hand, as I have two or three times feen the cynanche maligna epidemically prevailing; fo, among the perfons affeaed, I have feen inftances of cafes as mild as thofe of the fearlatina anginofa ufually are : but here the proportion was reverfed; and thefe mild cafes were not one fifth of the whole, while the reft were of the putrid and malignant kind. Lastly, It applies to the fame purpofe to obferve, that, of the cynanche maligna, moft of the inftances terminate fatally; while, on the other hand, that is the event of very few ofthe cafes ofthe fearlatina anginofa. 654.] From thefe confiderations, though it may appear that there is fome affinity between the cynanche maligna and fearlatina anginofa, it will ftill remain probable that the two difeafes are fpecifically different. I have been at fome pains to eftablifh this opinion : for, from all my ex- perience, I find, that thofe two difeafes require a different treatment; and I therefore now proceed to mention more particularly the circumftances ofthe fearlatina anginofa. 655.] This difeafe commonly appears about the begin- ning of winter, and continues throughout that feafon. It comes on with fome cold fhivering, and other fymptoms of the fever which ufually introduces the other exanthe- mata. But here there is no cough, nor the other catarrhal fymptoms which attend the meafies; nor is there that anx- iety and vomiting which commonly introduce the conflu- ent fmall-pox, and which more certainly introduce the Cynanche Maligna. Early in the difeafe, fome uneafinefs is felt in the throat; and frequently the deglutition is difficult, gericrally more fo than in the Cynanche Maligna. Upon looking into the fauces, a rednefs and fwelling appear in color and bulk ap- proaching to the ftate of thefe fymptoms in the Cynanche Tonfllaris • but in the Scarlatina, there is always more or 840 PRACTICE lefs of fioughs, which feldom appear in the Cynanche Tonfillaris; and the fioughs* are commonly whiter than thofe in the Cynanche maligna. While thefe appearances are difcovered in the fauces, upon the third or fourth day a fcarlet eruption appears on the fkin in the fame form as defcribed in (314.) This eruption is commonly more confiderable and univerfal than in the Cynanche; but it feldom produces a remiflion ofthe fever. The eruption for the moft part remains till the third or fourth day after its firft appearance; but then goes off, ending in ameally defquamation. At this time the fever ufually fubfides; and generally, at,the fame time, fome degree >f fweat comes on. ,Tbe fioughs on the fauces, which appeared early in the difeafe, continue for fome days; but then falling off, dif- cover the fwelling abated, and an ulcer formed on one or both tonfils fhowing a laudable pus; and foon after the fever has fubfided, thefe ulcers heal up entirely. For the moft part this difeafe has much lefs of coryza attending it than the Cynanche maligna; and, when there is a coryza attending the Scarlatina, the matter difcharged is lefs acrid, and has not the fetid fmell which it has in the other difeafe. In the Scarlatina, when the eruption has entirely difap- _ peared, it frequently happens, that, in a few days after, the whole body is affeaed with an anafarcous fwelling; which, however, in a few days more, gradually fubfides- We have thus defcribed the moft common circumftan- ces of the Scarlatina Anginofa; and have only to add, that during the time of its being epidemic, and efpecially upon its firft fetting in, there are always a few7 cafes in which the circumftances of the difeafe approach' very nearly to thofe ofthe Cynanche Maligna; s#& it is only in thefe inftances that the difeafe is attended with any danger.* 656.] With refpea to the cure of this difeafe, when the fymptoms of it are nearly the fame with thofe of the Cy- nanche Maligna, it requires exaaiy the fame treatment as direaed in (317.) • * "Jne e cafes in which the difeafe is attended with danger, are, however, v£ry few,, and are only the effect of art. Teazing the patient by doing too Koch"; tormenting him with a clofe confinement to his bed, well furnifhed wjjjfyilankets ; and adding fuel to the flame, by forcing him to fwallow large qcBj^Jllies cf cordials and alexipnarmics, are the fure methods of ii creating* ihf.d-feafe : and the patient, diftreffed by Ui* exceflive efficioufnefs of hi& fage decior,4s obliged to take refuge in the arras of Death. % OF PHYSIC. 241 657.] When the fcarlet fever appears, without any af- feaion ofthe throat, the treatment of it is very fimple, and is delivered by Dr. Sydenham. An antiphlogiftic regi- men * is commonly all that is requifite; avoiding, on one hand, the application of cold air; and, on the other, any increafe of external heat. 658.] In the ordinary ftate ofthe Scarlatina Anginofa, the fame treatment is, in moft cafes, fufficient; but as here the fever is commonly more confiderable, and there is likewife an affeaion ofthe throat, fome remedies may be often neceffary. 659.] When there is a pretty high degree of fever, with a full pulfe, and a confiderable fwelling of the tonfils, bleeding is very proper, efpecially in adults; and it has been frequently practifed with advantage : but as, even in the Cynanche Tonfillaris, much bleeding is feldom ne- ceffary ; (305.) fo, in the Scarlatina, when the ftate ofthe fever and the appearances of the fauces render the nature of the difeafe ambiguous, bleeding may be omitted ; and, if not altogether avoided, it fhould at leaft not be large, and ought not to be repeated. 65o.] Vomiting, and efpecially naufeating dofes of emetics,t notwithflanding the.inflamed ftate ofthe fauces, have been found very ufeful in this difeafe. An open belly is proper in every form of this difeafe; and when the nau- feating dofes of emetics operate a little downwards, they are more ferviceable. 661.] In every form ofthe Scarlatina Anginofa, through the whole courfe of it, detergent gargles J fhould be em- ployed, and more or lefs as the quantity of fioughs and the vifcid mucus in the faucus may feem to require. 662.] Even in the milder ftates of the Scarlatina Angi- nofa, it has been common with practitioners to'exhibit the Peruvian bark through the whole courfe of the difeafe; but we are affured, by much experience, that in fuch ca- * The«ntiphlogiftic regimen muft not however be carried too far, left we induce a ftate of debility that may prove hurtfuL t Thefe have been mentioned in former notes. f The detergent gargles were defcribed in the note on article 317.- Thac- i.ire of rofes is generally ufed, and in moft cafes anfwerevery intention.

CHAP. V. ©f tbz Plague* Sect. I. Ofthe Phenomena of the Plague. 664.] X HE Plague is a difeafe which always arifes from contagion ; which affeas many perfons about the fame time; proves fatal to great numbers, generally produces fever; and, in moft perfons, is attended with buboes or carbuncles. 665.] Thefe are the circumftances which, taken toge- ther, give the chara6ler ofthe difeafe; but it is accompa- nied with many fymptoms almoft peculiar to itfelf, that, in different perfons, are greatly diverfified in number and degree, and fhould be particularly ftudied. I would with to lay the foundation for this; but think it unfit for a per- fon who has never feen the difeafe to attempt its particular hiftory. For this, therefore, I muft refer to the authors who have written on the fubjea; but allowing thofe only to be confulted, who have themfelves feen and treated the difeafe in all its different forms. 666.] From the accounts of fuch authors, it appears to me, that the circumftances which particularly diftinguifh this difeafe, and efpecially the more violent and danger- ous ftates of it, are 15*, The great lofs of ftrength in the animal fun&ions, which often appears early in the difeafe. 2dly, The ftupor, giddinefs, and confequent ftaggering, which refembles drunkennefs, or the head-ach and various delirium; which are all of them fymptoms denoting a great diforder in the funaioris of the brain. %dly^ The anxiety, palpitation, fyncope, and efoccially OF PHYSIC. S42 the weaknefs and irregularity of the pulfe, which denotes a confiderable difturbance in the aaion of the heart. 4-thly, The naufea and vomiting, particularly the vo- miting of bile, which fhows an accumulation of vitiated bile in the gall-bladder and biliary ducts, and from thence derived into the inteftines and ftomach; all of which fymp- toms I fuppofe to denote a confiderable fpafm, and lofs of tone, in the extreme veffels on the furface ofthe body. $thly, The buboes or carbuncles, which denote an acri- mony prevailing in the fluids. And, Lastly, The petechia?, hemorrhagies, and colliquative diarrhoea, which denote a putrefcent tendency prevailing to a great degree in the mafs of blood. 667.] From the confideration of all thefe fymptoms, it appears, that the plague is efpecially diftinguifhed by a fpe- cific contagion, often fuddenly producing the moft confi- derable fymptoms of debility in the nervous fyftem or moving powers, as well as of a general putrefcency in the j fluids; and it is from the confideration of thefe circum- ftances as the proximate caufe, that I think both' the pre- vention and cure of the plague muft be direaed. 668.] If this difeafe fliould revifit the nothern parts of Europe, it is probable, that, at the time, there will be no phyficians th.cn alive, who, at the firft appearance of the difeafe, can be guided by his former experience, but muft be inftrucfed by his ftudy ofthe writers on this fuhjea, and by analogy. It is, therefore, I hope, allowable for me, upon the fame grounds, to offer here my opinion with refpecl to both the prevention and cure of this difeafe. This paragraph was written before I had any notice of, the plague of Mofeow anno 1771; but I think'it will ftill apply' to the cafe of Great Britain and of many othe| N northern ftates. Sect. II. Of the Prevention of the Plagut. 669.] WITH refpea to the prevention: As we are firmly perfuaded that the difeafe never arifes in the north- ern parts of Europe, but in confequence of its being im- ported from fome other country; fo the firft meafure ne- ceffary, is the magiftrate's taking care to prevent the em- 444 PRACTICE portation : and this may generally be done by a due at- tention to bills of health, and to the performance of qua- rantines. 670.] With refpea to the latter, we are perfuaded, that the quarantine of perfons may fafely be much lefs than forty days; and, if this were allowed, the execution of the quarantine would be more exaa and certain, as the temp- tation to break it would be in a great meafure removed. 671.] With refpea to the quarantine of goods, it can- not be perfea, unlefs the fufpected goods be unpacked and duly ventilated, as well as the other means employed for correcting the infeaion they may cany; and, if all this were properly done, it is probable that the time common- ly prefcribed for the quarantine of goods might alfo be fhortened. 672.] A fecond meafure, in the way of prevention, be- comes requifite, when an infeaion has reached and pre- vailed in any place, to prevent that infeaion from fprcad- ing into other places. This can be done only by prevent, ing the inhabitants, or the goods of any infected place, from going out of it, till they have undergone a proper quarantine. 673.] The third meafure for prevention, to be employ- ed with great care, is to hinder the infection from fprcading among the inhabitants of the place in which it has arifen. The meafures neceffary for this, are to be direaed by the doarine laid down in (82.) and from that doarine we infer, that all perfons who can avoid any near communication , with infeaed perfons, or goods, may efcape the infection. 674.] For avoiding fuch communication, a great deal 'jaay be done by the magifjtrate: 1. By allowing as many jpf the inhabitants as are free from the infeaion, and cot neceffary to the fervice of the place, to go out of it. 2. By prohibiting all affemblies, or unnecelfary intercourfe of the people. 3. By taking care that neceffary communi- cations be formed without contaa. 4. By making fuch arrangements and provifions as may render it eafy for the families remaining, to fhut themfelves up in their own houfes. 5. By allowing perfons to quit houles in which an infeaion appears, upon condition that they go into la- zarettoes. 6. By ventilating and purifying, or deftroying at the public expence, all affeaed goods. LatUy, by a- OF PHYSIC. 24S voiding hofpitals, and providing feparate apartments for infected perfons. The execution of thefe meafures will require great au- thority, and much vigilance and attention, on the part of the magiftrate; but it is not our province to enter into any detail on this fubject of the public police. 675.] The fourth and laft part ofthe bufinefs of pre- vention, refpeas the condua of perfons neceffarily remain- ing in infeaed places, efpecially of thofe obliged to have fome communication with perfons infeaed. 676.] Of thofe obliged to remain in infeaed places, but not obliged to have any near communication with the fick, they may be preferved from the contagion by avoiding all near communication with other perfons, or their goods; and it is probable, that a fmall diftance will anfwer the purpofe, if, at the fame time, there be no ftream of air to carry the effluvia of perfons, or goods, to fome diftance. 677.] For thofe who are neceffarily obliged to have a near communication with the fick, it is proper to let them know, that fome of the moft powerful contagions do not operate, but when the bodies of men expofed to the con- tagion are in certain circumftances which render them more liable to be affeaed by it; and therefore, by avoid- ing thefe circumftances and caufes, they may often efcape infection. 678.] The bodies of men are efpecially liable to be af- feaed by contagions, when they are any ways confiderably weakened by want of food, and even by a feanty diet, or one of little nourifhment; by intemperance in drinking, which when the ftupor of intoxication is over, leaves the body in a weakened ftate; by excefs in venery; by great fatigue; or by any confiderable evacuation. 679.] The caufes which, concurring with contagion, render it more certainly aaive, arc cold, fear, and full living. The feveral means, therefore, of avoiding or guarding againft the action of cold (94, to 96.) are to be carefully ftudied. 680.] Againft fear the mind is to be fortified as well as poffible, by infpiring a favorable idea of the power of pre- servative means; by deftroying the opinion of the incura- ble nature of the difeafe; by occupying mens minds with 2iG P n A C T I c ?. bufinefs or labour; and by avoiding all ohjefis of fear, ai funerals, pa'fing bells, and any notice of the death o.( par- ticular friends. 681.] A full diet of animal food increafes the irritabi- lity ofthe body, and favors the operation of contagion ; and in digeftion, whether from the quantity or quality of food, has the fame effea. 682. J Befides giving attention to obviate the feveral cir- cumftances (009, 678, to 681.) which favor the operation of contagion, it is probable that fome means may be em- ployed for ftrengthening the bodies of men, and thereby enabling them to refift contagion. For this purpofe, it is probahle, that the moderate ufe of wine, or of fpirituous liquors, may have a good effea. It is probable alfo, that exercife, when it can be em- ployed, if fo moderate asto.be neither heating nor fatiguing to the body, may be employed with advantage- Perfons who have tried cold bathing, and commonly feel invigorating effects from it, if they are any ways fe- cure againft having already received infection, may polfibly be enabled to refift it by the ufe of the cold bath. It is probable, that fome medicines alfo may be ufeful in enabling men to refift infection : but amongft thefe I can hardly admit the numerous alexipharmics formerly pro- pofed; or, at leaft, very few of them, and thofe only of tonic power. Amongft thefe laft we reckon the Peruvian bjik; ami it is perhaps the moft effeaual. If any thing is to be expeaed from antifeptics, I think camphire, whe- ther internally or externally employed, is one of the moft promiimg. Every perfon is to be indulged in the ufe of any means of prefervation of which he has conceived a good opinion, whether it be a charm or a medicine, if the latter be not directly hurtful. Whether iffues be ufeful in preferving from, or in mo- derating the effeas of contagion, I cannot determine from the obfervations I have yet read. 683.] As neither the atmofphere in general, nor anv confiderable portion of it, is tainted or impregnated with the matter of contagions; fo the lighting of fires over a great part of the infected city, or other general fumigati- OF PHYSIC- 5i7 ons in the open air, are of no ufe for preventing the dif- eafe, and may perhaps be hurtful. 684.] It would probably contribute much to check the progrefs of infection, if the poor were enjoined to make a frequent change of clothing, and were fuitably provided for that purpofe; and if they were, at the fame time, in- duced to make a frequent ventilation of their houfes and furniture. Sect. III. Of the Cure ofthe Plague. ■ 685.] IX the cure of the plague, the indications arc the fame as thofe of fever in general, (126.) but here they are not all equally ncceffary and important. . 686.] The meafures for moderating the violence of re- action, which operate by diminifhing the aaion of the heart and arteries (i28.)'have feldom any place here, ex- cepting fo far as the antiphlogiftic regimen is -proper. Some phyficians, indeed, have recommended bleeding; and there may occur cafes in which bleeding may be ufe- ful ; but, for the moft part, it is unneceffary, and in many cafes it might be very hurtful. Purging has alfo been recommended ; and, in fome de- gree, it may be ufeful in drawing off the bile, or other pu- trefcent matters frequently prefent in the inteftines; but a large evacuation this way may certainly be hurtful.' 687.] The moderating the violence of reaction, fo far as it can be done by taking off the fpafm of the extreme veffels (151.) is a meafure ofthe utmoft neceftity in the cure of the plague; and the whole ofthe means (152, to 200.) fuited to this indication are extremely proper. 688.] The giving an emetic at the very firft approach of the difeafe, would probably be of great fervice; and it . is likely, that at fome other periods of the difeafe emetics ' might be ufeful, both by evacuating bile abundant in the alimentary canal, and by taking off the fpafm of the ex- treme veffels. 689.] From fome principles with refpea to fever in general, and with refpecl to the plague in particular, I am of opinion, that, after the exhibition of the firft vomit, the body fiioulu be difpofed ty fweat; which ought to be raif- 2« PRACTICE ed to a moderate degree only, but continued for at leaft twenty-four hours, or longer if the patient bear it eafily. 690.] This fweating fhould be excited and conduaed agreeably to the rules laid down in 168. It is to be pro- moted by the plentiful ufe of diluents, rendered more grateful by vegetable acids, or more powerful by being impregnated with fome portion of neutral falts. 691.] To fupport the patient under the continuance of the fweat, a little weak broth, acidulated with juice of lemons, may be given frequently ; and fometimes a little wine, if the heat of the body be not confiderable. 692.J If fudorific medicines are judged to be neceffary, opiates are the moft effeaual and fafe : but they fhould not be combined with aromatics; and probably may be more effectual, if joined with a portion of emetics, and of neutral falts. 693.] If, notwithflanding the ufe of emetics and fudo- rifics, the difeafe fhould ftill continue, the cure muft de- pends upon the employment of means for obviating debi- lity and putrefcency; and for this purpofe, the various re- medies propofed above (from 201, to 227.) may be ad- miniftered, but efpecially the tonics; and of thefe the chief are cold drink and the Peruvian bark. 694.] In the cure ofthe plague, fome attention is due to the management of buboes and carbuncles : but we do not touch this, as it belongs to the province of furgery.* CHAP. VI. ©f GE^gipelatf, 01 <&t. ant&onp's jFire. 695.] XN 273,1 mentioned the diftinaion which I pro- pofed to make between the difeafes to be named the Ery- thema and the Eryfipelas; and from thence it will appear, that Eryfipelas, as an Erythema following fever, may have its place here. * The reader might poflibly expect a detail of the medicines ufed in the plague, with their dofes, and the manner of adminiftering them ; but I thought it better to refer to the authors who have either feen the difeafe, or whe have exprefsly written on it. On confulting different authors, it appears, that every particular epidemic requires a different treatment, in fome part of the cure at leaft. Should any young practitioner be unfortunate enough to have occafion to exercife his art in the cure of the plague, he mult chiefly be dire&ed by the general indica- tions of the cure of fevers. Of PHYSIC 249 696.*] I fuppofe the eryfipelas to depend on a matter generated within the body, and which, analogous to fhe Other cafes of exanthefitata, is, in confequence of fever, thrown out upon the furface ofthe body. I own it may be difficult to apply this to every particular cafe of eryfi- pelas : but I take the cafe in which it is generally fuppofed to apply, that of the eryfipelas of the face ; which I fhall therefore confider here. 697.] The Eryfipelas of the face comes on with a cold - , fhivering, and other fymptoms of pyrexia. The hot ftage of this is frequently attended with a confufion of head, and Come degree of delirium; and almoft always with drowfi- nefs, or perhaps coma. The pulfe is always frequent, and commonly full and hard. 698.] When thefe fymptoms have continued for one, two, or at moft three days, there appears, on fome part of the face, a rednefs, fuch as that defcribed in (275.) as the appearance of Erythema. This rednefs, at firft, is of no great extent; but gradually fpreads from the part it firft occupied to the other parts of the face, commonly till it has affeaed the whole; and frequently from the face it fpreads over the hairy fcalp, or defcends on fome part of the neck. As the rednefs fpreads, it commonly difappears, or at leaft decreafes, in the parts it had before occupied. All the parts upon which the rednefs appears are, at the fame time, affeaed with fome fwelling, which continues for fome time after the rednefs has abated. The whole face becomes confiderably turgid; and the eye-lids are often fo much fwelled as entirely to fhut the eyes. $99-] When the rednefs and fwelling have proceeded for fome time, there commonly arife, fooner or later, blif- ters of a larger or fmaller fize, on feveral parts, of the face. Thefe contain a thin yellowifh or almoft colourlefs liquor, which fooner or later runs out. The furface of the fkin, in the bliftered places, fometimes becomes livid and black- ifh ; but this livor feldom goes deeper than the furface, or difeovers any degree of gangrene affeaing the fkin. On the parts of the face not affeaed with blifters, the cuticle fuffers, towards the end of the difeafe, a confiderable def- quamation. Sometimes the tumour of the eye-lids ends in a fuppuration, Vu:. I. 1, 250 PR Ai; 1 tuh 700.] The inflammation coming upon the face does not produce any remiflion ofthe fever which had before prevailed ; and fometimes the fever increafes with the in- creafing and fpreading inflammation. 701.] The inflammation ufually continues for eight or ten days; and for the fame time, the fever and fymptoms attending it alfo continue. 702.] In the progrefs of the inflammation the delirium and coma attending it fometimes go on increafing, and the patient dies apopfeaic on the feventh, ninth, or eleventh day ofthe difeafe. In fuch cafes it has been commonly fuppofed that the difeafe is tranflated from the external to the internal parts. But I have not feen any inftance in which it did not appear to me, that the affeaion of the 1 brain was merely a communication of the external affec- tion, as this continued increafing at the fame time with the internal. 703.] When the fatal event does not take place, the in- flammation, after having affe6ted a part, commonly the whole of the face, and perhaps the other external parts of the head, ceafes. With the inflammation, the fever alfo ceafes; and, without any evident crifis, the patient returns to his ordinary ftate of health. 704.] This difeafe is not commonly contagious; but as it may arife from an acrid matter externally applied, fo it is poffible that the difeafe may fometimes be communicat- ed from one perfon to another. Perfons who have once laboured under this difeafe are liable to returns of it. 705.] The event of this difeafe may be forefeen from the ftate ofthe fymptoms which denote more or lefs affec- tion of the brain. If neither delirium nor coma come on, the difeafe is feldom attended with any danger; but when thefe fymptoms appear early in the difeafe, and are in a con- fiderable degree, the utmoft danger is to be apprehended. 1 706.] As this difeafe often arifes in the part, at the fame time with the coming on ofthe pyrexia; as I have know* i it with all its fymptoms, arife from an acrimony applied to the part; as it is commonly attended with a full, and fre- quently a hard pulfe; as the blood drawn in this difeafe fhows the fame cruft upon its furface, that appears in the phlegmafiae; and, laftly; as the fwelling ofthe eye-lids, in 0 F P'H Y S I C. 251 this difeafe, frequently ends in a fuppuration; fo, from thefe confiderations, it feems doubtful if this difeafe be properly, in Nofology, feparated from the Phlegmafiae. At any rate, I take the difeafe I have defcribed to be what phyficians have named the Eryfipelas Phlegmonodes, and that it partakes a great deal of the nature ofthe Phlegmafiae. 707.] Upon this conclufion, the Eryfipelas of the.face is to be cured very much in the fame manner as phlegmonic inflammations, by blood-letting,cooling purgatives, and by employing every part of the antiphlogiftic regimen ;* and our experience has confirmed the fitnefs of this method of cure. 708.] The evacuations of blood-letting and purging, are to be employed more or lefs according to the urgency of fymptoms, particularly thofe of the pyrexia, and of thofe which mark an affeaion ©f the brain.

At com- ing on, they are fometimes' attended with drowfinefs, and even with fome delirium; hut this rarely happens; and thefe fymptoms do not continue after the inflammation is formed. I have never feen an inftance of the tranflation of this inflammation from the limbs to an internal part; and though thefe inflammations of the limbs be attended with pyrexia, they feldom require the fame evacuations as the eryfipelas ofthe face. At firft they are to be treated by dry mealy applications only; and all humid applica- tions, as fomentations, or poultices, are not to be applied, till, by the continuance of the difeafe, by the increafe of fwelling, or by a throbbing felt in the part, it appears that the difeafe is proceeding to fuppuration. 712.] We have hitherto confidered -eryfipelas as in a great meafure of a phlegmonic nature; and agreeably to that opinion, we have propofed our method of cure. But it is probable, that an eryfipelas is fometimes attended with, or is a fymptom of, a putrid fever; and, in fuch cafes, the evacuations propofed above may be improper, and the ufe of the Peruvian bark may be neceffary ; but I cannot be explicit upon this fubjea, as fuch putrid cafes have not come under my obfervation.

Many practitioners recommend the application of cabbage leaves to ery- fipelatous fwellings, and their efficacy has been frequently approved. They ought to be removed as foon as they groW warm or uneafy, and frefh cold ones applied. * Hoffman, Welfch, and feveral other writers, fix the firft appearance of this difeafe at Leipfic in the years 1651 and 1652. This, opinion, however, is falfe ; for defcriptions of miliary eruptions are to be found in the writings of the ancients, and among the moderns we find Riverius defcribing it in OF PHYSIC. 253 have fpread from thence into all the other parts of Europe;* and, fincc the period mentioned, to have appeared in ma- ny countries in which it had never appeared before. 714.] From the time of its having been firft particular- ly obferved, it has been defcribed and treated of by many different writers ; and by all of them, till very lately, has been confidered as a peculiar idiopathic difeafe. It is faid to have been conftantly attended with peculiar fymptoms. It comes on with a cold ftage, which is often confiderable. The hot ftage which fucceeds, is attended with great anxiety, and frequent fighing. The heat of the body becomes great, and foon produces profufe fweating; preceded, however, by a fenfe of pricking, as of pin-points in the fkin; and the fweat is of a peculiar rank and dif- agreeable odour. The eruption appears fooner or later in different perfons, but at no determined period ofthe dif- eafe. It feldom or never appears on the face ; but dif- eovers itfelf firft upon the neck and breaft, and from thence often fpreads over the whole bodv. 715. J The eruption named Miliary is faid to be of two kinds, the one named the Red, the other the White Milia- ry. The former which in Englifh is ftriaiy named the Rath, is commonly allowed to be a fy mptomatic affeaion ; and as the latter is the only one that has any pretenfions 'tobe confidered as an idiopathic difeafe, it is this alone that I fhall -more paiticularly defcribe and treat of in the prefent chapter. 716.] What then is called the White Miliary eruption France, juft after the appearance of the comet in the year 1618 ; to which phenomena that author afcribes the fatal epidemic, as well as the bloody wars that were at that time making horrid devaftations in Europe. < We meet with feveral accounts of the appearance of the miliary eruption in different parts of Europe foon after the middle of the laft century, not on- ly by medical writers, bur by general hiftorians • among the latter'of whom we may mention Robert Sibbald, who takes notice of it in his Scotia illuf- trata, pubhmed at Edinburgh in the year 1684. (Sibbald, however, was a phyiician.) To enumerate the medical writers who have defcribed the dif- eafe in the different parts of Europe, would take,more room than the (hort compafs of thefe notes admit, the chief of them are Welfch, Hoffman Lan- gius Reyger, Bonetus, Grinwald, Sydenham, Ramizini, Fuchfius, &c. &c 1 he authors above mentioned, and feveral others about the end of the laft and beginning of this century, entertained various opinions conceminff the nature of the miliary eruption, fome of them fuppofing it to be a critical termination of a peculiar fever, and others on the contrary ftrenuoullv infill- ing that it was only accidental or fymptomatic, and never critical or falutary 1 he controverfy, which was carried on with fome warmth, is now terminat- ed as will appear by what follows ; but the inquifitive young phyfician will find both entertainment and inftruaion in perufing it. A very good abftraft of it occurs in De ilaen's treatife on the divifion of Fevers 954 PRACTICE appears at firft like the red, in very fmall red pimples, for the moft part diftina, but fometimes cluftered together. Their flight prominence is diftinguifhed better by the fin- ger than by the eye. Soon after the appearance of this eruption, and at leaft on the fecond day, a fmall veficle ap- pears upon the top of each pimpk^ At firft the veiicle is whey colored ; but foon becomes white, and. Hands out like a tittle globule on the top ofthe pimple. In two or three days, thefe globules break, or are rubbed off ; and are fucceeded by fmall crufts, which foon after fall off in fmall fcales. While one fet of pimples takes this courfe, another fet fucceeds; fo that the difeafe often continues upon the fkin for many days together. Sometimes when one crop of this eruption has appeared, another, after fome • interval, is produced. And it has been further obferved, that in fome perfons there is -fuch a tendency to this dif- eafe, that they have been affected w ith it feveral times in the courfe of their lives. 717.] This difeafe is faid to affea both fexes, and per- fons of all ages and conftitutions; but it has been obferved, at all times, to affea efpecially, and moft frequently, ly- ing-in women. 718.] This difeafe is often accompanied with violent fymptoms, and has frequently proved fatal. The fymp- toms attending it are, however, very various. They are, in one or other inftances, all the feveral fymptoms attend- ing febrile difeafes; but I cannot find that any fymptom or concourfe of fymptoms are fteadily the fame in differ- ent perfons, fo as to furnifh any fpecific character to the difeafe. When the difeafe is violent, the moft common fymptoms are phrenitic, comatofe, and convulfive affec- tions, which are alfo fymptoms of all fevers treated by a very warm regimen. 719.] While there is fuch a variety of fymptoms ap- pearing in this difeafe, it is not to be expeaed that any one particular method of cure can be propofed: and accord- ingly we find, in different writers, different methods and remedies prefcribed; frequent difputes about the moft proper; and thofe received and praaifed by fome, op- pofed and rejeaed by others. 720.] I have thus given an account of what I have found delivered by authors who have confidered the white OF PHYSIC. 255 miliary fever as an idiopathic difeafe: but, now, "after having often obferved the difeafe, I muft fay that I doubt much if it ever be fuch an idiopathic as has been fuppofed, and I fufpca that there is much fallacy in what has been written on the fubjea. ^ 721.] It feems to me very improbable, that thfe1 fhould have been really a new difeafe when it was firft ccfcifidered as fuch. There appear to me very clear traces of it in au- thors who wrote long before that period; "and, though there were not, we know that the defcriptions of the anci- ents were inaccurate and imperfea, particularly with ref- pea to cutaneous affeaions; whilft we know alfo very well, that thofe affections which ufually appeared as fymp- tomatic only, were commonly negfeaed, or confounded together under a general appellation. 722.] The antecedent fymptoms of anxiety, fighing, and pricking of the fkin, which have been fpoken of as pe- culiar to this difeafe, are, however, common to many others; and, perhaps to all thofe in which fweatings are forced out by a warm regimen. Of the fymptoms faid to be concomitant of this erup- tion, there are none which can be conftant and peculiar but that of fweating. This, indeed, always precedes and accompanies the eruption ; and, while the miliary eruption attends many different difeafes, it never, however, ap- pears in any of thefe, but after fweating; and, in perfons labouring under thefe difeafes, it does not appear, if fweat- ing be avoided. It is therefore probable, that the erupti- on is the effea of fweating; and that it is the produce of a matter, not before prevailing in the mafs of blood, but generated, under particular circumftances, in the fkin it- felf. That it depends upon particular circumftances ofthe fkin, appears further from hence, that the eruption fel- dom or never appears upon the face, although it affeas the whole ofthe body befides; that it comes upon thofe places efpecially which are more clofely covered; and that it can be brought out upon particular parts by external applications. 723.] It is to be obferved, that this eruptive difeafe dif- fers from the other exanthemata in many circumftances; in its not being contagious, and therefore never epidemic; that the eruption appears at no determined period of the 256 PRACTICE difeafe; that the eruption has no determined duration; that fucceffive eruptions frequently appear in the courfe ofthe fame fever; and that fuch eruptions frequently oc- cur in the courfe of the fame perfon's life. All thefe circumftances render it extremely probable, that, inMe miliary fever, the morbific matter is not a fub- fifting contagion communicated to the blood, and thence, in confequence of fever and affimilation, thrown out upon the furface ofthe body ; but a matter occafionally pro- duced in the fkin itfelf, by fweating. 724.] This conclufion is further rendered probable from hence, that, while the miliary eruption has no pecu- liar fymptoms, or concourfeof fymptoms, belonging to it; yet upon occafion, it accompanies almoft all febrile dif- eafes, whether inflammatory or putrid, if thefe happen to be attended with fweating; and from thence it mav be prefumed, that the miliary eruption is a fymptomatic affec- tion only, produced in the manner we have faid. 725.] But, as this fymptomatic affeaion does not al- waysac.company every inflance of fweating, it may be pro- perlo inquire what are the circumftances which efpecially determines this eruption to appear ? To this, however, I can give no full and proper anfwer. I cannot fay that there is any one circumftance which in all cafes gives oc- cafion to the eruption; nor can I fay what different caufes may, in different cafes, give occafion to it. There is on- ly one obfervation I can offer to the purpofe of this in- quiry ; and it is, that, of the perfons, fweating under feb- rile difeafes, thofe are efpecially liable to miliary eruption, who have been previoufly weakened by large evacuations, particularly of blood. This will explain why it happens to lying-in women more frequently than to any other per- fons ; and to confirm this explanation, I have remarked, that the eruption happened to women not in child-bed, but who had been much fubjeaed to a frequent and copi- ous menftruation; and to an almoft conftant fluor albus. I have alfo had occafion to obferve it happen to men in fevers, after wounds from which they had fuffered great lofs of blood. Further, that this eruption is produced by a certain ftate of debility, will appear probable, from its often occurring in fevers of the putrid. kind7 which are always attended OF PHYSIC. 257 with great debility. It is true, that it alfo fometimes at- tends inflammatory difeafes, when it cannot be accounted for in the Tame manner ; but I believe it will be found to attend efpecially thofe inflammatory difeafes in which the fweats have been long protrafcfed or frequently repeated, and which have thereby produced a debility, and perhaps a debilitating putrid diathefis. 726.] It appears fo cleaily to me that this eruption is always a fymptomatic* and faaitious affeaion, that I am perfuaded it may be in moft cafes prevented merely by avoiding fweats. Spontaneous fweatings, in the begin- ning of difeafes, are very rarely critical; all fweatings, not evidently critical, fliould be prevented ; and the promot- ing them, by increafing external heat, is commonly very pernicious. Even critical fweats fliould hardly be en- couraged by fuch means. If, therefore, fpontaneous fweats -arife, they are to be checked by the coolnefs of the cham- ber ; by the lightnefs and coolnefs of the bed-clothes; by the pcrfon's laying out their hands and arms, and by their taking cold drink: and, by thefe precautions, I think I have frequently prevented miliary eruptions, which were otherwife likely to have appeared, particularly in lying-in women. 727.] But it may happen, when thefe precautions have been neglected, or from other circumftances, that a milia- ry eruption does aaually appear; and the queftion will then be put, how the cafe is to be treated ? It is a queftion of confequence, becaufe I believe that the matter here ge- nerated is often of a virulent kind; it is frequently the off- fpring of putrefcency ; and, when treated by increafing the external heat of the body, it feems to acquire a virulence which produces thofe fymptoms mentioned in 718. and proves certainly fatal. * As this difeafe is always fymptomatic and never idiopathic, the method of curing muft neceffarily vary in different cafes ; the chief attention of the phy- fician muft therefore be turned to the primary difeafe, and to the meaus of preventing this fymptom from appearing in thofe difeafes \fhich it accom- panies. The author judicioufly begins his method of cure by giving dire&ions for preventing the eruption, which he properly fuppofes to be entirely faaitious, and to depend on the application of too much heat. With a proper atten- tion to the direftions given in the teyt, we may. in general prevent the erup- tion. I f, however, the eruption is prefent before the phyfician is called, thofe remedies muft be ufed for i<* removal that are enumerated in the fubfecruent articles. \ CM.. I. K K . 958 PRACTICE It has been an unhappy opinion with moft phyficians, that eruptive difeafes were ready to be hurt by cold ; and that it was therefore neceffary to cover up the Dody very clofely, fo as thereby to increafe the external heat-. We now know that this is a miftaken opinion; that increafing the external heat of the body is very generally mifehiev- ous; and that feveral eruptions not only admit, but require the application of cold air. We are now* perfuaded, that the praaice which formerly prevailed, in the cafe of mi- liary eruptions, of covering up the body clofe, and both fc by external means, and internal remedies, encouraging the fweatings which accompany this eruption, was highly pernicious, and commonly fatal. I am therefore of opi- nion, even when a miliary eruption has appeared, that in all cafes where the fweating is not manifeftly critical, we fhould employ all the feveral means of flopping it that are mentioned above ; and I have fometimes had occafion to obferve, that even the admiflion of cool air was fafe and ufeful. 728.] This is, in general, the treatment of miliary e- ruptions; but, at the fame time, the remedies fuited to the primary difeafe, are to be employed; and therefore, when the eruption happens to accompany inflammatory affeaions, and when the fulnefs and hardnefs of the pulfe or other fymptoms fhow an inflammatory ftate prefent, the cafe is to be treated by blood-letting, purging, and other antiphlogiftic remedies. Upon the other hand, when the miliary eruption attends difeafes in which debility and putrefcency prevail, it will be proper to avoid all evacuations, and employ tonic and * The prefent rational pra&ice has entirely akered the regimen in fevers; and inftead of macerating the patient in a hot bed, and obliging him to breathe the corrupt air of a confined chamber, we now cover him with light bed-clothes, and ventilate his room. It may, however, be neceffary to guard the young phyfician againft the ex- cefs of this praftice. The precept, Omne nimium nocet, fhould always b« attended to. If the patient feels any difagreeabte effeas, or if he fhould fuf- fer rigors, or trembles from the admiffion of cold air, it is certainly prejudi- cial, and its admiffion ought to be regulated. It may not be improper to mention another caution, viz. That the young praftitioner muft not, by the means here recommended, check fweats that irt really critical. To determine what fweats are, and what are not, critical, is perhaps, in fome cafes, attended with confiderable difficulty. In general how- ever, critical fweats may be known by their happening on the critical days before mentioned in articles 107. et feq. and by their always being immediately followed by an abatement of all, or at leaft the greateft part of tbt; fymptcitrt.

I fhall conclude this fubjea with mentioning, that the venerable octogenarian praaitioncr, de Fifcher, when treating of this fubjea, in laying down the indications of cure, has given this as one of them: " Excretionis peri- phericae non primariam habere rationem."

In this I follow Dr. Hoff- man, who joins the aaive hemorrhagies with the febrile difeafes; and have accordingly eftablifhed thefe hemorr- hagies as an order in the clafs of Pyrexiae. From this or- der I exclude all thofe eifufions of red blood that are ow- ing entirely to external violence; and all thofe which, though arifing from internal caufes, are, however, not au tended with pyrexia, and which feem to be owing to a pu- trid fluidity of the blood, to the weaknefs or to the erolioii ofthe veffels, rather than to any increafed impetus ofthe blood in them. 736.] Before proceeding to treat of thofe proper he- morrhagies^which form an order in our Nofology, I fhall treat of aaive hemorrhagy in general; and indeed the fe- veral genera and fpecies, to be treated of particularly af- terwards, have fo many circumftances in common with one another, that the general confideration to be now of- fered will prove both proper and ufeful. Sect. I. ,, = <\ Of the Phenomena of Hemorrhagy. 737.] THE phenomena of hemorrhagy are generally the following. Hemorrhagies happen efpecially in plethoric habits, and to perfons of a fanguine temperament. They appear moft commonly in the fpring, or in the beginning of fummer. For fome time, longer or fhorter in different cafes, be- fore the blood flows, there are fome fymptoms of fulnefs £63 PRACTICE and tenfion about the parts from whence the blood is to iffue. In fuch parts as fall under our view, there are fome rednefs fwelling, and fenfe of heat or of itching; and in the internal parts from which blood is to flow, there is a fenfe of weight and heat; and, in both cafes, various pains are often felt in the neighbouring parts. 738.] When thefe fymptoms have fubfifted for fome time, fome degree of a cold ftage of pyrexia comes on, and a hot ftage is formed; during which, the blood flows of a florid color, in a greater or leffer quantity, and continues to flow for a longer or a fhorter time ; but commonly, af- ter fome time, the effufion fpontaneoufly ceafes, and to- gether with it the pyrexia alfo. 739-] During the hot ftage which precedes an hemorr- hagy, the pulfe is frequent, quick,* full, and often hard; but, as the blood flows, the pulfe becomes fofter and left frequent. 740.] In hemorrhagies, blood drawn from a vein, does, upon its concreting, commonly fhow the gluten feparated, or a cruft formed, as in the cafes of Phlegmafiae. 741.] Hemorrhagies from internal caufes, having once happened, are apt, after a certain interval, to return; in fome cafes very often, and frequently at ftated periods. 742.] Thefe are, in general, the phenomena of hemorr- hagy; and if in fome cafes all of them be not exquifkely marked, or if perhaps fome of them do not at all appear, it imports only, that, in different cafes the fyftem is more or lefs generally affeaed; and that, in fome cafes, there are purely topical hemorrhagies, as there are purely topi- cal inflammations. Sect. II. Of the Proximate Cause ef Hemorrhagy. 743.] THE pathology of hemorrhagy feems to be fuf- ficiently obvious. Some inequality in the diftribution of the blood, occafions a congeftion in particular parts of the fanguiferous fyftem; that is, a greater quantity of blood is poured into certain veffels than their natural capacity is fuited to receive. Thefe veffels become thereby, preter- * The difference between a frequent and quick pulfe was mentioned in a note on article 336. OF PHYSIC 563 naturally diftended; and this diftention, proving a ftimulus to them, excites their afction to a greater degree than ufual, which pufhing the blood with unufual force into the ex- tremities of thefe veffels, opens them by anaftomofis, or rupture; and, if thefe extremities be loofely fituated on external furfaces, or on the internal furfaces of certain ca- vities that open outwardly, a quantity of blood flows out of the body. 744.] This reafoning will, in fome meafure, explain the produaion of hemorrhagy. But it appears to me, that, in moft cafes, there are other circumftances that occur to produce it; for it is probable, that, in confequence of con<- geftion, a fenfe of refiftance arifes, and excites the aaion of the Vis Medicatrix Naturae, the exertions of which are ufually made by the formation of a cold ftage of pyrexia, inducing a more vigorous action of the veffels; and the concurrence of this exertion more effeaually opens the extremeties, and occafions the flowing out of the blood. 745.] What has been delivered in the two preceding paragraphs, feems to explain the whole phenomena of he- morrhagy, except the circumftance of its frequent recur- rence, which I apprehend may be explained in the follow- ing manner. The congeftion and confequent irritation being taken off by the flowing of the blood; this, therefore, foon after, fpontaneoufly ceafes; but, at the fame time, the internal caufes which had before produced the unequal diftribution of the blood, commonly remain, and muft now operate the more readily, as the over-ftretched and relaxed veffels of the part will more eafily admit of a con- geftion of blood in them, and, confequently, produce the fame feries of phenomena as before. 746.] This may fufficiently explain the ordinary return of hemorrhagy: but there is ftill another circumftance, which, as commonly concurring, is to be taken notice of; and that is, the general plethoric ftate of the fyftem, which renders every caufe of unequal diftribution of more confi- derable effea. Though hemorrhagy may often depend upon the ftate of the veffels of a particular part being fa- vourable to a congeftion's being formed in them; yet, in order to that ftate's producing its effea, it is neceffary that the whole fyftem fliould be at leaft in its natural plethork condition; and, if this fhould be in any degree increafed 264 PRACTICE beyond what is natural, it \* ill ftill more certainly deter- mine the effeas of topical confoimation to take place. The return of hemorrhagy, therefore, will be more cer- tainly occafioned, if the fyftem becomes preternaturally plethoric; but hemorrhagy has always a tendency to in- creafe the plethoric ftate ofthe fyftem, and, confequently, to occafion its owrn return. 747.] To fhow that hemorrhagy does contribute to produce or increafe the plethoric ftate of the fyftem, it is only neceffary to obferve. that the quantity of ferous fluids being given, the ftate of the excretions depends upon a certain balance between the force of the larger arteries pro- pelling the blood, and the refiftance of the excretories: but the force ofthe arteries depends upon their fulnefs and diftenfion, chiefly given to them by the quantity of red globules and gluten, which are, for the greateft part con- fined to the red arteries; and therefore, the spoliation made by an hemorrhagy, being chiefly of red globules and glu- ten, the effufion of blood muft leave the red arteries more empty and weak. In confequence of the weaker aaion of the red arteries, the excretions are in proportion dimi- nifhed ; and, therefore, the ingefta continuing the fame, more fluids will be accumulated in the larger veffels. It is by this means that the lofs of blood by hemorrhagies, whether artificial or fpontaneous, if within certain bounds, is commonly fo foon recovered : but as the diminution of the excretions, from a lefs quantity of fluid being impelled into the excretories, gives occafion to thefe veffels to fall into a contraaed ftate; fo, if this fhall continue long, thefe veffels will become more rigid, and will not yield to the fame impelling force as before. Although the arte- ries, therefore, by new blood colfeaed in them, fhall have recovered their former fulnefs, tenfion, and force; yet this force will not be in balance with the refiftance of the more rigid excretories, fo as to reftore the former ftate of excretion; and, confequently, a further accumulation will take place in the arteries, and an increafe of their pletho- ric ftale be thereby induced. In this manner, we perceive moreclearly, that hemorrhagy, as producing a more ple- thoric ftate of the fyftem, has a tendency to occafion its own recurrence with greater violence; and, as the renewal and further accumulation of blood require a determinate OF PHYSIC. 265 time, fo, in the feveral repetitions of hemorrhagy, that time will be nearly the fame; and therefore the returns of he- morrhagy will be commonly atftated periods, as has been obferved frequently to happen. 748.] I have thus explained the nature of hemorrhagy in general, as depending upon fome inequality in the diftri- bution of the blood, occasioning a congeftion of it in par^ ticular parts of the fanguiferous fy ftem. It is indeed pro- bable, that, in moft perfons, the feveral parts of the fan- guiferous fyftem, are in balance with one another; and that the denfity, and confequently the refiftance, in the fevcral veffels, is in proportion to the quantity of blood which each fliould receive; from whence it frequently happens, that no inequality in the diftribution of the blood takes place in the courfe of a lor.5 life. If, however, we confider that the fanguiferous fyftem is conftantly in a ple- thoric ftate, that is, that the veffels are conftantly diftend- ed beyond that fize which they would be of, if free from any di{tending force, we fliall be fatisfied that this ftate may be readily changed. For as, on the one hand, the veffels are elaftic, fo as to be under a conftant tendency to contraa upon the withdrawing of any part of the defend- ing force; and, on the other hand, are not fo rigid but that, by an increafe ofthe impetus of the blood in them, they may be more than ordinarily diftended; fo we can eafily underftand how, in moft perfons, caufes of an in- creafed contraaion or diftenfion may arife in one part or other ofthe fyftem, or that an unequal diftribution may take place ; and how, in an exquifitely diftended or ple- thoric fyftem, a fmall inequality in the diftribution ofthe blood may form thofe congeftions which give occafion to hemorrhagy. 749.] In this manner I endeavour to explain how he- morrhagy may be occafioned at any period of life, or in any part of the body : but hemorrhagies happen in cer- tain parts more frequently than in others, and at certain periods of life more readily than at others; and therefore, in delivering the general doarine of hemorrhagy, it may be required that I fhould explain thofe circumftances which produce the fpccialities mentioned ; and I fliall now at- tempt it. • Vor. I. I. 1. 266 PRACTICE 75°-] The human body, from being of a finall bulk at its firft formation, grows afterwards to a confiderable fize. This increafe of bulk confifts, in a great meafure, in the increafe of the quantity of fluids and a proportional en- largement of the containing veffels. But at the fame time, the quantity of folid matter is alfo gradually increafed; and, in whatever manner we may fuppofe-this to be done, it is probable that the progrefs, in the whole growth of animal bodies, depends upon the extenfion of the arterial fyftem ; and fuch is the conftitution of the fanguiferous fyftem, that the motion of the blood in the arteries has a conftant tendency to extend them in every dimenfion. 751.] As the ftate of the animal folid is, at the firft form- ation of the body, very lax and yielding ; fo the extenfion of the fyftem proceeds, at firft, very fait: but, as the ex- tenfion gives occafion to the appofition of more matter to the folid parts, thefe are, in proportion to their extenfion, conftantly acquiring a greater denlity, and therefore giving more refiftance to their further extenfion and growth. Ac- cordingly, we obferve, that as the growth of the body ad- vances, its increafe, in any given time, becomes propor- tionally lefs, till at length it ceafes altogether. 752.] This is the general idea of the growth ofthe hu- man body, till it attain the utmoft bulk which it is capable of acquiring : but, it is to be remarked, that this growth does not proceed equally in every part of the body, it be- ing requifite for the ceconomy of the fyftem, that certain parte fhould be firft evolved, and fhould alfo acquire their full bulk fooner than others. This appears particularly with refpea to the head, the parts of which appear to be firft evolved, and fooneft to acquire their full fizes. 753.] To favour this unequal growth, it is prefumed, that the dimenfions or the laxity of the veffels of the head, or that the direaion of the force of the blood, are adapted to the purpofe; and from what has been faid in 751. it will alfo certainly follow, that as the veffels of the head . grow fafteft, and fooneft acquire their full fize, fo they will fooneft alfo acquire that denfity which will prevent their further extenfion. While, however, the force of the heart, and the quantity of the fluids, with refpea to the whole fyfteim, remain the fame, the diftending and extend- ing powers will be direaed to fuch parts as have not yet O F P H Y S I C. 267 acquired the fame denfity and dimenfions of thofe firft evolved; and the diftending and extending powers will proceed to operate till every part ofthe fyftem, in refpea of denfity and refiftance, fhall have been brought to be in balance with every other, and till the whole be in balance with the force of the heart, fo that there can be no further growth in any particular part, unlefs fome preternatural circumftance fhall happen to arife. 754.] In this procefs ofthe growth ofthe body, as it feems in general to depend upon a certain balance between the force of the heart, or diftending power, and the refift- ance of the folids; fo it will appear, that, while the folids remain very lax and yielding, fome occafional increafe of the diftending power may arife without producing any very perceptible diforder in the fyftem. But, it will alfo ap- pear, that, in proportion as the diftending power and re- fiftance ofthe folids come to be more nearly in equal bal- ance with one another, fo any increafe of the diftending power will more readily produce a rupture of veffels, which do not eafily yield to extenfion. 755-] from all this, it muft follow, that the effeas of any unufual plethoric ftate ofthe fyftem, will be different according as this fliall occur at different periods of the growth of the body. Accordingly, it is evident, that if the plethoric ftate arifes while the head is yet growing, and while the determination of the blood is ftill more to the head than to the other parts, the increafed quantity of the blood will be efpecially determined to the head; and as there alfo, at the fame time, the balance between the dif- tending and extending power is moft nearly adjufted, fo the determination of the blood will moft readily produce in that part a rupture of the veffels, or an hemorrhagy. Hence it is, that hemorrhagies of the nofe fo frequently happen to young perfons; and in thefe more readily, as they approach nearer to their acme, or full growth; or, if it may be faid, perhaps more properly, as they approach nearer to the age of puberty, when, perhaps, in both fexes, but efpecially in the female, a new determination arifes in the fyftem. 756.] The determination of a greater quantity of blood to the veffels of the head, might be fuppofed to occafion a rupture of veffels in otlier parts of the head; as- well as in 26S PRACTICE the nofe : but fuch a rupture does not commonly happen; becaufe in the nofe there is, for the purpofe of fenfe, a confiderable net work of blood-\ cffels expanded on the internal furface of the noftrils, and covered only with thin and weak teguments. From this circumftance it is, that upon any increafed impetus of the blood in the veffels of the head, thofe of the nofe are moft eafily broken; and the effufion from the nofe taking place, it not only relieves the other extremities of the external carotid, to which the arteries of the nofe chiefly belong, but relieves alfo, in a great meafure, the fyftem of the internal carotid. For, from the internal carotid, certain branches are fent to the nofe, are fpread out on its'internal furface, and probably1 inofculated with the extremities of the external carotid: fo that, whichfoever of the extremities are broken, the vii derivation^ of Haller will take place; the effufion will re- lieve the whole fanguiferous fyftem of the head; and the fame effufion will alfo commonly prevent an hemorrhagy happening at the fame time in any other part of the body. 757.] From thefe principles, it will appear why he- morrhaies of the nofe, fo frequent before the period of puberty, or of the acme, feldom happen after thefe peri- ods: and I muft obferve further, that although they fliould occur, they would not afford any objeaion to my doarine, as fuch hemorrhagies might be imputed to a peculiar lax- ity of the veffels of the nofe, and perhaps to a habit ac- quired with refpea to thefe veffels, while the balance of the fyftem might be otherwife adjuftcd. 758.] When the procefs ofthe growth ofthe body goes on regularly, and the balance of the fyftem is properly ad- jufted to the gradual growth of the whole, as well as to the fucceffive growth of the feveral parts, even a plethoric ftate does not produce any hemorrhagy, or at leaft any af- ter that of the nofe : but if, while the plethoric ftate con- tinues, any inequality fliall alfo fubfift in any ofthe parts of the fyftem, congeftions, hemorrhagic or inflammatory, « may be ftill readily formed. 759-] Jn geneiai? ft ixiay be obferved, that, when the feveral parts of the fyftem of the aorta have attained their full growth, and are duly balanced with one another, if then any confiderable degree of plethora remain or arife, the nicety of the balance will be between the fy Items ofthe OF PHYSIC. 269 aorta and pulmonary artery, or between the veffels of the lungs and thofe of all the reft of the body. And although the leffer capacity of the veffels of the lungs is commonly compenfated by the greater velocity ofthe blood in them ; yet, if this velocity be not always adjufted to the neceffary compenfation, it is probable that a plethoric ftate ofthe whole body will always be efpecially felt in the lungs; and, therefore, that an hemorrhagy, as the effea of a ge- neral plethora, may be frequently occafioned in the lungs, even though there be no fault in their conformation. 760.] In fome cafes, perhaps, an hemorrhagy from the lungs, or an hemoptyfis, does arife from the general ple- thoric ftate of the body ; but an hemoptyfis more frequent- ly does, and may be expeaed to happen, from a faulty proportion between the capacity of the lungs and that of the reft of the body. 761.] When fuch a difproportion takes place, it will be evident, that an hemoptyfis will efpecially happen about the time that the body is approaching to its acme ; that is, when the fyftem of the aorta has arrived at its utmoft ex- tenfion and refiftance, and when, therefore, the plethoric ftate of the whole muft efpecially affea the lungs. 762.] Accordingly, it has been conftantly obferved, that the hemoptyfis efpecially occurs about the time ofthe body's arriving at its acme ; but I muft remark alfo, that the hemorrhagy may occur fooner or later, according as the balance between the veffels of the lungs, and thofe of the fyftem of the aorta, happen to be more or lefs exa6tly adjufted to one another ; and it may, therefore often occur much later than the period mentioned, when that balance, though not quite even, is however not fo ill adjufted, but that fome other concurring caufes are neceffary to give it effea. 763.] It was anciently remarked by Hippocrates, and has been confirmed by modern obfervation, that the he- moptyfis generally occurs in perfons between the age of fifteen and that of five and thirty; that it may happen at any time between thefe two periods; but that it feldom happens before the former, or after the latter; and it may be proper here to inquire into the reafon of thefe two li- mitations. •- *sro PRACTICE 764.] With refpea to the firft, the reafon of it has been already explained in 761, and 762. With refpea to the fecond limitation, I expea that the reafon of it will be underftood from the following conli- derations. It has been already obferved, that the extenfion and growth of the body require the plethoric ftate of the ar- terial fyftem ; and nature has provided for this, partly by the conftitution of the blood being fuch, that a great por. tion of it is unfit to pafs into the exhalents and excreto- ries ; partly by giving a certain denfity and refiftance to the feveral exhalents and excretories through which the fluids might pafs out of the red arteries ; and partly, but efpecially, by a refiftance in the veins to the free paffage of the blood into them from the arteries. 765.] With refpea to this laft and chief circumftance, it appears from rhe experiments of Sir Clifton Wintring- ham, in his Experimental Inquiry, that the proportional denfity ofthe coats ofthe veins to that of the coats of the arteries, is greater in young than in old animals: From which it may be prefumed, that the refiftance to the paf- fage of the blood from the arteries into the veins, is great- er in young animals than in old; and, while this refiftance continues, the plethoric ftate of the arteries muft be con- ftantly continued and fupported. As however the denfity of the coats of the veffels confifting chiefly of a cellular texture, is increafed by preffure ; fo, in proportion as the coats of the arteries are more expofed to preffure by dif- tenfion than thofe ofthe veins, the former, in the progrefs of the growth of the body, muft increafe much more in denfity than the latter; and, therefore, the coats of the ar- teries, in refpea of denfity and refiftance, muft come, in time, not only to he in balance with thofe of the veins, but to prevail over them : a faa which is fufficiently prov- ed by the experiments of the abovementioned ingenious author. By thefe means, the proportional quantities of blood in the arteries and veins muft change in the courfe of life. In younger animals, the quantity of blood in the arteries muft be proportionally greater than in old ones; but by the in- creafing denfity of the arteries, the quantity of blood in, them muft be continually diminifhing, and that in the veins OF PHYSIC. 271 be proportionally increafing, fo as at length to be in a pro- portionally greater quantity than that in the arteries. When this change happens in the proportional quantities of the blood in the arteries and veins, it muft be evident that the plethoric ftate of the arteries will be in a great meafure taken off; and, therefore, that the arterial hemorrhagy is no longer likely to happen ; but that, if a general pletho- ric ftate afterwards takes place in the fyftem, it muft efpe- cially appear in the veins. 766.] The change I have .mentioned to happen in the ftate of the arterial and venous fyftems, is properly fup- pofed to take place in the human body about the a-e of thirty-five, when it is manifeft that the vigour of the body, which depends fo much upon the fulnefs and tenfion ofthe arterial fyftem, no longer increafes; and therefore it is, that the fame age is the period, after which the arterial he- morrhagy, hemoptyfis, hardly ever appears. It is *^iic, there are inftances of the hemoptyfis happening at a later period; but it is for the reafons given (757.) which fhow that an hemorrhagy may happen at any period of life, from accidental caufes forming congeftions, independent of the ftate of the balance ofthe fyftem at that particular period. 767.] I have faid (765.) that if, after the age of thirty- five, a general and preternatural plethoric ftate occur, it muft efpecially appear in the venous fyftem; and I muft now obferve, that this venous plethora may alfo give oc- cafion to hemorrhagy. 768.] If a plethoric ftate of the venous fyftem take place, it is to be prefumed, that it will efpecially and in the firft place affect, the fyftem of the vena portaru'ra, in which the motion of the venous blood is more flow than elfewhere; in which the motion ofthe blood is little affifted by exter- nal compreffion; and in which, from the want of valves in the veins that form the vena portarum, the motion of the blood is little affifted by the compreffion that is appli- ed; while, from the fame want of valves in thofe veins, the blood is more ready to regurgitate in them. Whether any regurgitation of the blood can produce an aaion in the veins, and which inverted, or directed towards their ex- tremities, can force thefe, and occafion hemorrhagy. may perhaps be difputed : but it appears to me that an hemorr- hagy, produced by a plethoric ftate of the veins, may be 272 PRACTICE explained in another and more probable manner. If the blood be accumulated in the veins, from an eruption of its proper courfe, that accumulation muft refift the free paffage of the blood from the arteries into the veins. This again muft produce fome congeftions in the extremities of the red arteries, and therefore feme increafed aaion in them, which muft be determined with more than ufual force, both upon the extremities of the arteries, and upon the exhalants proceeding from them ; and this force may occafion an effufion of blood, either by anaftomofis or rupture. 769.] In this manner I apprehend the hemorrhoidal flux is to be explained, fo far as it depends upon the ftate of the whole fyftem. It appears moft commonly to proceed from the extremities of the hemorrhoidal veffels, which, being the moft dependent and diftant branches of thofe vernsf that form the vena portarum, are therefore the molt readily affeaed by every accumulation of blood in that fyftem of veins, and confequently by any general plethora in the venous fyftem. 770.] It is here to be obferved, that I have fpoken of this hemorrhagy as proceeding from the hemorrhoidal vef- fels only, as indeed it moft commonly does; but ii will be readily underftood, that the fame accumulation and refift- ance to the venous blood may, from various caufes, affea many of the extremities of the vena portarum, which lie very fupcrficially upon the internal furface of the alimen- tary canal, and give occafion to what has been called the Morbus Niger or Mclcena. 771.] Another part in which an unufually plethoric ftate of the veins may have particular effeas, and occafion hemorrhagy, is the head. In this, the venous fyftem is of a peculiar conformation, and fuch as feems intended by nature to give there a flower motion to the venous blood. If, therefore, the plethoric ftate of the venous fyftem in general, which feems to increafe as life advances, fhould at length increafe to a great degree, it may very readily affea the venous veffels of the head, and produce there fuch a refiftance to the arterial blood, as to determine this to be poured out from the nofe, or in the cavity of the cranium. The fpecial effea of the latter effufion will be, to produce the difeafe termed Apoplexy; and which, OF PHYSIC. 273 therefore, is properly named by Do&or Hoffman, He- morrhage Cerebri: and the explanation of its caufe, which I have now given, explains well why it happens ef- pecially to men of large heads and fhort necks, and to men in the decline of life, when the powers promoting the mo- tion of the blood are much weakened. 772.] I have thus attempted to give the hiftory of the plethoric and hemorrhagic ftates of the human body, as they occur at the different periods of life ; and hope I have thereby explained, not only the nature of hemorrhagy in general, but alfo ofthe particular hemorrhagies which moft commonly appear, and as they occur fucceflively at the different periods of life. Sect. III. Ofthe Remote Causes of Hemorrhagy. 773.] IN the explanation hitherto given, I have efpe- cially confidered the predifpofition to hemorrhagy; but it is proper alfo, and even neceffary; to take notice of the occafional caufes, which not only concur with the predif- ponent, in exciting hemorrhagy, but may alfo fometimes be the fole caufes of it. 774.] Thefe occafional caufes are, 1. External heat, which, by rarefying the blood, pro- duces or increafes the plethoric ftate of the body; and the fame heat, as giving a ftimulus to the whole fyftem, muft urge any particular determinations before eftablifhed, ftill further, or may urge to excefs any inequality, otherwife innocent; fo that, in either way, external heat may im- mediately excite hemorrhagies, to which there was a pre- difpofition, or may form congeftions where there were none before, and thereby occafion hemorrhagy. 2. A confiderable and fudden diminution of the weight ofthe atmofphere, which feems to occafion the fame effeas as heat, by producing alfo an cxpanfion of the blood. 3. Whatever increafes the force of the circulation, and thereby the velocity of the blood, may operate in the fame manner as heat, in urging not only previous determina- tions wj,th violence, but alfo in urging to excefs inequali- ties, otherwife innocent. All violent exercife; thereforej Vor. 1. M si 274 PRACTICE and efpecially all violent efforts, which, not only by a Jarger and longer infpiration, but alfo by the fimultancous aaion of many mufcles interrupting the free motion of the blood, impel it with unufual force into the extreme veffels more generally, and, according to the different poftures of. the body, and mode of the effort, into certain veffels more particularly. Among the caufes increafing the force ofthe circulation, anger* and other violent aaive paffions are to be reckoned. 4. The violent exercife of particular parts of the body. If thefe are already affeaed with congeftions, or liable to them, fuch exercife may be confidered as a ftimulus ap- plied to the veffels of that particular part. Thus, any violent exercife of refpirationt may excite hemoptyfis, or occafion its return. 5, The poftures of the body increafing determinations, or ligatures occafioning accumulations of the blood in par- ticular parts of the body. 6. A determination into certain veffels rendered habitual by the frequent repetition of hemorrhagy from them. 7. Cold, externally applied, as changing the diftribu- tion of the blood, and determining it in greater quantity into the internal parts. ~~sIcV. IV. Of the Cure cf Hemorrhagy. 775.] HAVING thus confidered the proximate and remote caufes of hemorrhagy in general, our next bufinefs is, to treat of the cure of the difeafe in the fame manner. In entering upon this fubjeel, the firft queftion which prefents itfelf, is, Whether the cure of hemorrhagies ought to be attempted by art, or if they fhould be left to the con- dua of nature ? 776.] The latter opinion was the favourite doarine of the celebrated Dr. Stahl, and his followers. They maintained, that the human body is much difpofed to a plethoric ftate; and, confequently, to many diforders which * Paffionate children frequently bring on a bleeding of the nofe; and wben /uch an.accident happens, the child's face, before the blood breaks out, be- comes red, and all the veffels of the head and neck feem diftended and full. f A.s playing on the German flute, or any other wind inllrument that K' «uires a great force to blow it. OF PHYSIC. in nature endeavours to obviate and relieve by exciting he- * morrhagy : that this, therefore, is often neceffary to the balance and health of the fyftem : that it is accordingly to be generally encouraged, fometimes folicited, and is not to be fuppreffed, unlefs when it goes to great excefs, or happens in parts in which it may be dangerous. 777.] Much of this doarine may be admitted. The human body, upon many occafions, becomes preternatu- rally plethoric; and the dangerous confequences which might from thence be apprehended, feem to be obviated by an hemorrhagy taking place: and, further, the neceffity of hemorrhagy often appears from hence, that the fup- preffion of it feems to occafion many diforders. All this feems to be juft; but, in the conclufion drawn from it, there is a fallacy. 778.] It appears to me certain, that hemorrhagy, either upon its firft attack, or upon its after recurrence, is never neceffary to the health of the body, excepting upon the fnppofition, that the plethoric ftate which feems to require the evacuation, cannot be otherwife prevented or removed; and as I imagine it poffible by other means to prevent or remove a plethoric ftate, fo I do not think that hemorrha- gy is,, in all cafes, ncceffary. In general, I am of opini- on, that hemorrhagy is to be avoided. 1. Becaufe it does not always happen in parts where it is fafe. 2. Becaufe often, while it does relieve a plethoric ftate, it may, at the fame time, induce a very dangerous difeafe. 3. Becaufe it may often go to excefs, and either endan- ger life, or induce a dangerous infirmity. And, laftly, Becaufe it has a tendency to increafe the plethoric ftate it was meant to relieve; to occafion its own recurrence, (720.) and thereby to induce a habit, which, if left to the precarious and unequal operation of nature, may, from the frequent errors of this, be attended with much danger. 779.] It is further tobe confidered, that hemorrhagies do not always arife from the neceflities of the fyftem, but often proceed from incidental caufes. It appears to me, that all hemorrhagies of the latter kind may be immediately fuppreffed, and the repetition of thcm; as it induces a pie. 275 PRACTICE thora, and a habit not otherwife neceffary may be pre- vented with great advantage. 780.] Upon the whole of this fubjea I conclude, that every preternatural hemorrhagy, or, in other words, every one except that of the menfes in females, is to be avoided, and efpecially the returns of it prevented ; and I therefore now proceed to mention, how hemorrhagy, and its recur- j rences, may, and fliould be prevented. 781.] From the principles delivered above, it will im- mediately appear, that the prevention, either of the firft attacks, or the returns of hemorrhagy, will chiefly, and ' in the firft place, depend upon the preventing or removing, any confiderable degree of a plethoric ftate which may happen to prevail in the body. It is true, that, where the hemorrhagy depends upon the particular conformation of certain parts, rather than upon the general plethoric ftate of the whole; the meafures for removing or preventing the latter, may not always be fufficient for preventing he- morrhagy : but at the fame time it muft be evident, that determinations, in confequence of the conformation of particular parts, will always be urged more or lefs, in pro- portion to the greater or leffer degree of the plethoric ftate of the whole fyftem; and therefore, that, even in the cafes depending upon particular conformation, the preventing or removing an unufually plethoric ftate, will always be a chief means of preventing hemorrhagy. It is further to be attended to, that there may be feveral inequalities in the balance ofthe fyftem, which may have little or no ef- fea unlefs when the fyftem becomes prctcrnaturally ple- thoric; and therefore, that, in all cafes, the preventing or removing of the plethoric ftate of the fyftem, will be a chief means of preventing the firft attacks, or the returns of hemorrhagy. It now, therefore, remains to explain, how the plethoric ftate of the fyftem is to be prevented or removed. 782.] The fluids of the human body are in continual 1 wafte -by the excretions, but are commonly replaced by ' the aliments taken in; and if the quantity of aliments in any meafure exceed that of the excretions, an increafe of the quantity of the fluids of the body, or, in other words, a plethoric ftate, muft neceffarily arife. This, to a cer- tain degree, is requifite for the growth of the body, but, j'i O F P H Y S I C. 277 -even then, if the proportion of the aliments to the excre- tions, be greater than is fuited to the growth of the body, and more certainly ftill, if, after the growth is completed, when an equality between the ihgesta and the excreta fhould be eftablifhed, the difproportion ftill continue, a preterna- turally plethoric ftate muft arife. In both cafes, it is evi- dent, that the plethora muft be prevented or correaed by adjufting the ingefta and excreta to each other; which ge- nerally may be done, either by diminifhing the ingefta, or by increafing the excreta.* The former may be effected by the management of the diet, the latter by the manage- ment of exercife. 783.] The ingefta may be diminifhed, either by giving aliment in lefs quantity than ufual, or by giving aliments of a lefs nutritious quality; that is, aliments of a fubftance which, under the fame bulk and weight, contain lefs of a matter capable of being converted into animal fluids, and more of a matter ready to pafs off by the excretions, and confequently lefs of a matter to be retained and accumu- lated in the veffels. The choice of aliments fuited to thefe purpofes muft he left to be direaed by the doarines ofthe Materia Medica. 784.] The increafing of the excreta, and thereby dimi- nifhing the plethoric ftate of the fyftem, is to be obtained by increafing the exercife of the body; and generally for adjufting the balance between the ingefta and excreta, and thereby obviating the plethoric ftate, it is neceffary that exercife, in a due meafure, be very conftantly employed.t 785.] The obferving abftinence, and the employment of exercife, for obviating or removing the plethoric ftate of the body, were formerly confidered pretty fully, when treating ofthe gout, (547, to 551.) fo that the lefs is ne- ceffary to be faid here : and it is now only requifite to ob- ferve, that the fame doubts, as in cafe of the gout, do not occur here with regard to the fafety of thofe meafures, * This effeft may furely be more fpeedily produced by ufeing both thefe means at once. t The exercife bell adapted to thefe cafes is fuch as does not heat the body or increafe the force of the blood. Hence riding- moderately, travelling iu a carriage, or failing, are preferable to walking. Young people may nfe fuch gentle exercife as may amufe the mind, and at the^fame time conduce to bo- dily health, as gardening, feveral agricultural labours, or mechanical opera- tions ; or fome of the fports that require a gentle bodilv exertion, as bow lii^g, archer/, Stc. 27* PRACTICE which, in a plethoric ftate of the body difpofing to he- morrhagy, are always admiflible and proper. Flere, how- ever, it is to be obferved, that fome choice in the mode of exercife is neceffary, and that it fhould be different ac- cording to the particular determinations which may hap- pen to prevail in the fyftem. In general, in the cafe of plethora difpofing to hemorrhagy, bodily exercife will al- ways be hazardous, and geftation more commonly fafe. 786.] Artificial evacuations may be employed to di- minifh the plethoric ftate of the body: and when, at any time, it has become confiderable, and immediately threat- ens a difeafe, thefe evacuations fhould be made to the quantity that the fymptoms feem to require. But it is conftantly to be attended to, that blood-lettings are impro^ perly employed to prevent a plethora, as they have a ten- dency to increafe it (720.) and as they require to be often repeated, and are thereby apt to induce a habit which may be attended with much danger.* 787.] While a plethora, and thereby the predifpofition to hemorrhagy, is avoided, or removed, the other mea- fures neceffary for preventing the occurrence of this, are thofe for avoiding the remote caufes. Thefe have been enumerated in 774, and the means of avoiding them, fo far as within our power, are fufficiently obvious. * Brilk purges are perhaps preferable to every other mode of evacuating the ingefta; and in thefe cafes we may have recourfe to draftics without any apprehenfion of danger.

Z79 788.] Having thus mentioned the means of preventing either the firft attacks, or the recurrence of hemorrhagy ; I muft next fay how it is to be managed when it has aaual- ly come on. 789.] When an hemorrhagy has come on which ap- pears to have arifen from a prctematurally plethoric ftatef^ or from fome change in the balance of the fanguiferous fyftem, no meafures are to be immediately taken for fup- preffing it; as we may expea, that, when the quantity of blood neceffary for the relief of the fyftem is poured out, the effufion will fpontaneoufly ceafe.* 790.] In many cafes however, it may be fufpeaed, that the quantity of blood poured out, is not exaaiy in proportion to the neceflities of the fyftem, either for reliev- ing a general plethora or a particular congeftion, but that it is often to a greater quantity than thefe require. This we fuppofe to happen in confequence of an inflammatory diathefis prevailing, and of a febrile fpafm being formed; and therefore it is in many cafes proper, as well as for the moft part fafe, to moderate the evacuation, and, when it threatens to go to excefs, to fupprefs it altogether. 791.] An hemorrhagy may be moderated by avoiding any irritation that might concur to increafe it; fo that every part ofthe antiphlogiftic regimen is to be obferved; particularly external heat, both as it rarefies the fluids, and ftimulates the folids, is to be carefully avoided: and, it is probable, than in all cafes an hemorrhagy may be fafely moderated by cool air applied, and cold drink exhibited. 792.] A fecond means for the fame purpofe. is, the ufe of refrigerant medicines, and particularly of acids and nitre.t • The doctrine here delivered, and the practice founded on it, is pure Stah- lianifm ; and is, doubtlefs, in thefe cafes the beft practice. A patient, how- ever, is not always fatisfied when the phyfician is inailive, which often ob- liges him to prelcribe fome of the medicamenta inertiora, and the choice of them mult be left to the practitioner's own fagacity. •f The refrigerant medicines have been enumerated in former notes, arti- cles 134, and 135. The Tinetura rofarum is a very proper acid refrigerant in rauft hemorrhagies. The dofe of it muft be proportioned to the exigency of the cafe ; it ought never to exceed four ounces in the fpace of an hour; an ounce every half hour is generally fufficient, and a greater quantity at a time frequently occafions gripes, and by its irritation increafes the difeafe; efpe- cially if it dots not produce a diarrhoea which is feldom the cafe. With ref- pecl to nitre, the precautions, mentioned in the note on article J35, muft be obferved. The dulcified fpirit of vitriol or of nitre are npt always fafe me- dicines in thefe cafes as they heat and irritate. The acid of tartar, in the form defcribed in the note on urtLU 134. anfwers very well in molt cafts. + SO PRACTICE 793.] A third means which has been frequently em- ployed, is that of blood-letting. The propriety of this practice may be doubtful, as the quantity of blood pour- ed out by the hemorrhagy, may be fuppofed to anfwer the purpofe of an evacuation in any other way; and I am •pready to allow, that the practice has been often fuperflu- - ous, and fometimes hurtful, by making a greater evacua- tion than was neceffary or fafe. At the fame time, I ap- prehend it is not for the mere purpofe of evacuating, that blood-letting is to be praaifed in the cure of hemorrhagy; but that it is further ncceffary for taking off the inflamma- tory diathefis which prevails, and the febrile fpafm that has been formed. Accordingly, in the cafe of hemorrha- gy, when the pulfe is not frequent, but quick and full, and does not become foftcr or flower upon the flowing of the blood, and that the effufion is profufe, and threatens to continue fo, it appears to me, that blood-letting may be neceffary, and I have often found it ufeful. It feems pro- bable alfo, that the particular circumftances of venefettion may render it more powerful for taking off the tenfion and inflammatory irritation of the fyftem, than any gradual flow from an artery. 794.] That a fpafm ofthe extreme veffels has a fhare in fupporting hemorrhagy, appears to me probable from hence, that bliftering has been often found ufeful in mo- derating and fupprcfling the difeafe. 795.] Do emetics and vomiting contribute to the cure of h|mprrhagy ? See Dr. Bryan Robinson on the vir- tues and power of medicines. 796.] When an hemorrhagy is very profufe, and feems to endanger life, or even threatens to induce a dangerous infirmity, it is agreed on all hands, that it is to be imme- diately fuppreffed by every means in our power, and par- ticularly that, befides the means above-mentioned for mo- derating the difeafes, aftringents, internal or external, where the latter can be applied, are to be employed for fuppreffing it. 797.] The internal aftringents are either vegetable or foflil. The vegetable aftringents are feldom very powerful in the cure of any hemorrhagies, except thofe of the alimen- tary canal. OF PH Y SIC. 23i The foffil aftringents arc more powerful; but fome choice amongft the different kinds may be proper. The chalybeats, fo frequently employed, do not appear to me to he very powerful. -.:);.. ; The preparations of lead are certainly more fo, tmr are other.vife of fo pernicious a quality, that they flifirrlH not % "* be employed except in cafes of the mm oft danger. The«^ Thfetura Saturnina, or Antiphthifica, as it has been called,^V' appears to be of little efficacy;* but whether from the finall portion of lead which it contains, or from die ftate in which the lead is in it, I am uncertain. The foffil aftringent that appears to me the moft pow- erful, and at the fame time the moft fafe, is alum.t 798.] External aftringents, when they can be applied, are more effeaual than the internal. The choice of thefe is left to the furgcons. 799.] The moft powerful of all the aftringents appears to me to be cold, which may be employed, either by ap- plying cold water to the furface of the body, or by thfefw- ing it into the internal parts.^ rr#j-" 8oq.J For fuppreffmg hemorrhagies, many fupfrftitious remedies and charms || have been recommended, and pre- tended to have been employed with fuccefs. The feeming fuccefs of thefe, however, has been generally owing to the by-ftanders miftaking a fpontaneous ceafing of the hemorr- hagy for the effea of the remedy. At the fame time, I believe, that thofe remedies may have been fometimes ufeful, by impreffing the mind with horror, awe, or dread. * It is a very dangerous medicine, and ought to be ufed with the uttnoft, caution. But fince its efficacy is doubtful, we had better abandon it altoge- ther, except when every other remedy Fails. f Alum frequently irritates if given in too large dofes at firft, p>o*ing fometimes a purgative and fometimes an emetic. In cafes of great danger,, however, it mult be given in large quantities by frequently repeating fmall dofes. Five grains is a fufficient dofe to begin with ; but it may be repeated every hour, or every half hour. Some authors have given it in dofes of a fcruple feveral times a day ; but that is certainly too great a quantity at once. f Van Swieten relates a cafe of a bleeding at the nofe being ltopped by the application of pledgets, dipped in cold wine and water, to the fcrotum * a lhivering was produced, and the bleeding Hopped. || It is ait'>nii1ring that thefe charms iliouf I continue in ufe in this enlight- ened age. They are nraftifed among the country people frequently. Some of them, however, aa mechanically, as the application ofthe great key of the church-door to the nape of the neck, in bleedings at the nofe ; drinking large draughts of cold water out of a human fcull, &c. The cold iron and the cold water were in fail proper remedies. Vol. i, N n ?8U PRACTICE 801.] Upon occafion of the profufe hemorrhagies, opi- ates hav*e been employed with advantage; and, when the fulnefs and inflammatory diathefis ofthe fyftem have.been previoufly taken off by the hemorrhagy itfelf, or by blood- letting, I think opiates may be employed with fafety.* 802.] For reftraining hemorrhagy, ligatures have been applied upon the limbs, in the view of retarding the return of the venous blood from the extremities ; but they ap- pear to me to be of uncertain and ambiguous ufe. 803.] In the cafe of profufe hemorrhagies, no pains are to be taken to prevent a Deliquium Animi, or fainting, as the happening of this is often the moft certain means of flopping the hemorrhagy.t 804.] Having thus delivered the general doarine of he- morrhagy, I proceed to confider the particular cafes of it. It may perhaps be remarked, that I have marked fewer of thefe than are commonly enumerated by the nofologifts; but my reafons for differing from thefe authors, muft be left to a nofological difcuffion, to be entered into elfewhcre more properly than here. CHAP.

The blood flowing from both noftrils at the fame time, fhows commonly a more confiderable difeafe. 807.] This hemorrhagy happens to perfons of every conftitution and temperament, but moft frequently to thofe * Opium, however, ought to be cautioufly employed in aaive hemorrha- gies, which are frequently accompanied with a phlogiftic diathofis ; opium is generally, if not univerfally, hurtful. But, as the author observes, when the hemorrhagy has reduced the inflammatory diathefis, we may then give opium freely: and for this purpofe large dofes are preferable to fmaller ones." f Attention, however, is neceffary in this cafe, as fainting is frequently tJw forerunner of death. 0 F P H Y S I C. 283 of a plethoric habit and fanguine temperament. It hap- pens to both fexes, but moft frequently to the male. 808. J This hemorrhagy may occur at any time of life ; but moft commonly happens to young perfons, owing to the ftate ofthe ballance of die fyftem peculiar to that age, as mentioned in (755.) 809. j Although generally it happens to perfons before they have arrived at their full growth, and more rarely af- terwards ; yet fometimes it happens to perfons after their acme, and during the ftate of manhood : And it muft then be imputed to an unufually plethoric ftate of the fyftem ; to an habitual determination of the blood to the veffels of the nofe; or to the particular weaknefs of thefe. 810.] In all thefe cafes the difeafe may be confidered as an hennorrhagy purely arterial, and depending upon an arterial plethora ; but it fometimes occurs in the decline of life, when probably it depends upon, and may be confi- dered as a mark of a venous plethora of the veffels of the head. See (771.) 811.] This hemorrhagy happens alfo at any period of life, in certain febrile difeafes, which are altogether or part- ly of an inflammatory nature, and which fhow a particular determination of the blood to the veffels of the head. Thefe difeafes. often admit of a folution by this hemorrha- gy, when it may be properly termed critical. 812.] The difeafe fometimes comes on without any pre- vious fymptoms; particularly, when fome external vio- lence has a fhare in producing it. But, when it proceeds entirely from an internal caufe, it is commonly preceded by hcadachs, rednefs of the eyes, a florid colour of the face, an unufual pulfation in the temples, a fenfe of ful- nefs about the nofe, an an itching of the noftnls.. A round belly, pale urine, coldnefs of the feet, and cold fhi- veringover the whole body, are alfo fometimes among the fymptoms that precede the difeafe 813. J From the weaknefs of the veffels of the nofe, the blood often flows from them without any confiderable ef- fort of the whole fyftem, and therefore without any ob- fervable febrile diforder; which, however, in many cafes, is, iu all its circumftances, very difcernable. 814.] An hemorrhagy of the nofe happening to young perfons, b; and may generally be confidered as a flight 584 PRACTICE difeafe of little confequence, and hardly requiring any re- medy. But, even in young perfons, when it recurs wry frequently, and is very copious, it will require particular attention, as it is tobe confidered as a mark of arierial plethora; and, as frequently returning, it may increafe the plethoric itate ; which, in a more advanced 11 age of life, may give the blood a determination to parts from which the hemorrhagy would be more dangerous. All this will more particularly require attention, according as the marks of plethoi a, and of a particular congeftion, preceding the hemorrhagy, are more confiderable; and as the flowing of the blood is attended with a more confiderable degree of febrile diforder. 815.] When the epiftaxis happens to perfons after their acme, returning frequently, and flowing copioufly, it is ah ways to be confidered as a dangerous difeafe, and as more certainly threatening the confcquences mentioned in the laft paragraph. 816.] When this hemorrhagy happens in the decline of life, it may he confidered as in itfelf very falutary: but at the fame time, it is to be confidered as a mark of a very dangerous ftate of the fyftem ; that is, as a mark of a very ftrong tendency to a venous plethora in the veffels of the head: and I have accordingly obferved it often followed by apoplexy, palfy, or fuch like difeafes. 817.] When an hemorrhagy from the nofe happens in febrile difeafes, as mentioned in 811, and is in pretty large quantity, it may be confidered as critical and falutary; but his very apt to be profufe, and even in this way dangerous. It upon fome occafions occurs during the eruptive fever of feveral exanthemata, and in fuch cafes fometimes falu- tary; but, if thefe exanthemata be accompanied with any putrid tendency, this hemorrhagy, like artificial blood-let- tings, may have very bad effeas. 818.] Having thus explained the feveral circumftances of epiftaxis, I proceed to confider the management and cure of it. I ufe the exprefiion of management, becaufe it has been ufually thought to require no cure, but that nature fhould be allowed to throw out blood in this way very frequently; and as often as it appears to arife from inter- nal caufes, that is, from a ftate of the fyftem fuppofed to require fuch evacuation. OF PHYSIC. 285 819.] I am however, of opinion, for the reafons given in (778.) that this difeafe is very feldom to be left to the conduct of nature; and that in all cafes it fliould be mo- derated by keeping the patient in cool air; by giving cold drink; by keeping the body and head crea; by avoiding any blowing of the nofe, fpeaking, or other irritation: And, when the blood has flowed for fome time, without frK)\ving any tendency to ceafe, a profufe bleeding is to be prevented by meafures employed to flop it, fuch as pref- fing the noftril from which the blood flows, waffling the face with cold water, or applying this to other parts of the body. 820.] Even in the cafe of young perfons, where the dif- eafe is leaft hazardous, and even in the firft attaas, I judge fuch meafures to be proper; but they will be ftill more proper if the difeafe frequently recurs without any external violence; if the returns fhall hsquen to perfons of a habit difpofed to be plethoric; andniore»rticularly, if the marks of a plethoric ftate appear in the-pwrcedent fymptoms (812) 8ii.] Even in young perfons, if the bleeding be very profufe and long continued, and more efpecially if the pulfe become weak and the face pale, I apprehend it will be pro- per to fupprefs the hemorrhagy by every means in our pow- er. See (796.) and following paragraphs.* 822.] Further, in the fame cafe of young perfons, when the returns of this hemorrhagy become frequent, and ef- pecially with the marks of a plethoA habit, I think it ne- ceffay to employ fuch a regimen as may prevent-a pletho- ric ftate, (782. 786.) At the fame time, care fhould be taken to avoid all circumftances which may determine the blood more fully to the veffels ofthe head, or prevent its free return from them ; and, by keeping an open belly to make fome derivation from them.t 8 2 3.

Ofthe Phenomena and Cause of the Phthisis Pulmonalis. 852.] JL HE Phthifis Pulmonalis I would define to be, an expeaoration of pus or purulent matter from the lungs, attended with a fever. As this is the principal fpecies of phthifis, I fhall fre- quently in this chapter employ the general term of phthifis, though ftrictly meaning the phthifis pulmonalis. 853.] I have met with fome inftances of an expeaorati- on of purulent matter, continuing for many years, accom- panied with very few fymptoms of he6tic, and at leaft with- out any heaic exquifitely formed : But, in none of thefe inftances, were the perfons fo entirely free from fymptoms of hectic, as to form any exception to the general definiti- on. 854.] In every inftance of an expeaoration of pus, I prefume there is an ulceration of the lungs. The late Mr. Haen is the only author that I know of, who has advanced another opinion, and has fuppofed, that pus may be form- ed in the blood-veffels, and be from thence poured into the bronchiae. Admitting his faa, I have attempted an explanation ofthe appearance of pus without ulceration in (349.) but, after all, I cannot help fufpeaing the accura- cy of his obfervations; muft entirely reject his explanation of them; muft however allow, that we ftill want faas to dill .lived in twenty times it's weight of water, and fweetened with a little fyrup of rofes, is alio a fuitable drink. A deco&ion either of the frelh fruit of quinces, fweetened with fugar, or an infufion of quince marmalade, is another e*cellent acid aftringent. In addition to what has been faid, it may be proper to obferve, that cpium is admiffible only in very few cafes of he- moptyfis; viz. when the hemoptyfis is the cenfequence of coughing. Thefe cafes are very difficultly diftinguifhed. If the blood be thrown out into the lungs, a cough is excited for its difcharge, and then the hemoptyfis is the primary difeafe ; in this cafe opium does more harm than good.—But if a cough.arifing from any other irritating caufe, than extravafated blood in the lungs fliould by its violence and long continuance, produce an hemoptyfis, then opium, joined with fuch remedies as are fuitable to remove the peculiar irritation, is the onlv medicine on which we can have any reliance ; and in thefe cafes we muftuie it in largedqfes, fuch as forty or fifty drops of laudanum. O b t ft Y S I C. 295 fupport the explanation I have offered; and doubt much if it will apply to any cafe of phthifis. For thefe realbns I ftill conclude, agreeably to the faith of all other diffeai- ons, and the opinions of all phyficians, that the fymptoms mentioned in our definition depend always upon an ulcera- tion formed in the lungs. 855.] It has fometimes happened, that a catarrh was attended with an expectoration of a matter fo much refem- bling pus, that phyficians have been often uncertain whe- ther the difeafe was mucus or pus, and therefore whether the difeafe was a catarrh or a phthifis. It is often of con- fequence to determine thefe queftions; and it appears to me that it may be generally done, with fufficient certainty, from the following confederations, of which each particu- lar is not always fingly decifive, but when they are taken together can hardly deceive us. 1. From the colour pFtheorffter; as mucus is natural- ly tranfparent, ancj^pus alwifr^sopaque. When mucus be- comes opaque, as it fometimes does, it becomes white, yellow, or gre>nifh; but the laft mentioned colour is hard- ly ever fo remarkable in mucus as in pus. 2. From the confidence; as mucus is more vifcid and coherent, and py»s lefs fo, and may be more friable. When mucus is thrown into water, it is not readily diffufed, but remains united in uniform and circular maffes : but pus, in the fame circumftances, though not readily diffufed, does not remain fo uniformly united, and by a little agita- tion is broken into ragged fragments. 3. From the odour; which is feldom perceived in mu- cus, but frequently in pus. It has been propofed to try the odour of the matter expectorated, by throwing it upon live coals; but in fuch a trial both mucus and pus give out a difagrecable fmell, and it is»not eafy to diftinguifh be- tween them. 4. From the fpecific gravity compared with water; and indeed, it is ufual for the mucus ofthe lungs to fwim on the furface of water, and for ufus to fink in it. But in this we may fometimes be deceives; as pus which has entangled a great deal of air may fwim, and mucus that is free from air may fink. 5. From the mixture which is difcernable in the matter brought up; for if a yellow or gujeftifh matter appears fur- «S PRACTICE " rounded with a quantity of tranfparent or lefs opaque and lefs coloured matter, the more ftrongly coloured matter may be generally confidered as pus; as it is not eafy to undcrftand how one portion ofthe mucus of the lungs can be very confiderably changed, while the reft of it is very little fo, or remains in its ordinary ftate. 6. From the admixture of certain fubftances with the matter thrown out from the lungs. To this purpofe we are informed by the experiments ofthe late Mr. Charles Darwin: a. That the vitriolic acid diflolves both mucus and pus, but moft readily the former: That, if water be added'Jo fuch a folution of mucus, this is feparated, and either fwims on the furface, or, divided into flocculi, is fufpended in the liquor; whereas, when water is added to a like folution of pus, this falls to the bottom, or by agita- tion is diffufed fo as to exhibit a uniformly turpid liquor. b. That a folution ofthe qiuftic fixed alkali, after feme time, diflolves mucus, and generally pus; and, if water be added to fuch folutions, the pus is precipitated, but the mucus is not. From fuch experiments it is.fuppofed, that pus and mucus may be certainly diftinguifhed from each other. 7. From the expeaoration's being attended with a hec- tic fever. A catarrh, or expeaoration of mucus, is often attended with fever: but never, fo far as I have obferved, with fuch a fever as I am prefently to defcribe as a heaic. This, in my opinion, is the moft certain mark of a puru- lent ftate in fome part of the body; and if others have thought differently, I am perfuaded that it has been owing to this, that, prefuming upon the mortal nature of a con- firmed or purulent phthifis, they have confidered every cafe in which a recovery happened, as a catarrh onlv: but, that they may have been miftaken in this, fhall be fhown hereafter. 856.] Having thus confidered the firft part of the cha- raaer of the phthifis pulmonalis as a mark of an ulcerati- on ofthe lungs ; and having juft now faid, that the other part of the character, that is, the heaic fever, is a mark or indication ofthe fame thing; it is proper now to confi- der this here, as I had with that view omitted it before (74.) 857.] A heaic fever has the form of a remittent, which OF PHYSIC. S9f —i—■-= • -hA has exacerbations twice every day. The firft of thefe oc- curs about noon, fometimes a little fooner or later; and a flight rcmiffion of it happens about five afternoon. '"*This laft is foon fucceeded by another exacerbation, gradually increafing till after midnight: But after two o'clock of the morning, a remiffion takes place, which becomes more and more confiderable as the morning advances. The exacerbations are frequently attended with fome degree of cold fhivering; or at leaft, the patient is exceedingly fen- fiblc to any coolnefs of the air, feeks external heat, and often complains of a fenfe of cold, when, to the thermo- meter, his fkin is preternaturally warm. Of thefe exacer- bations, that ofthe evening is always the moft confiderable. 858. j It has commonly been given as a part ofthe chai raaer of a heaic fever, that an exacerbation of it com- monly appears after the taking food; and it is true that dinner, which is taken at noon or after it, does feem to occafion fome exacerbation, But this muft not make us judge the mid-day exacerbation to be the effea of eating only; for I have often obferved it to come on an hour be- fore noon, and often fome hours before dinner; which, in this country at prefent, is not taken till fome time after- noon. It is indeed to be obferved, that in almoft every perfon, the taking food occafions fome degree of fever: but I am perfuaded this would not appear fo confiderable in a heaic, were it not that an exacerbation of fever is prefent from another caufe; and accordingly, the taking food in the morning has hardly any fenfible effea. 859. ] I have thus defcribed the general form of heaic fever; but many circumftances attending it, are further to be taken notice of. The fever I have defcribed does not commonly fubfift long, till the evening exacerbations become attended with fweatings; which continue to recur, and to prove more and more profufe, through the whole courfe ofthe difeafe. Almoft from the firft appearance of theheaic, the urine is high-coloured, and depofites a copious branny red fe- diment, which hardly ever falls clofe to the bottom of the veffel. In the heftic, the appetite for food is generally lefs im- paired than in any other kind of fever. Y<.u I. pf 23* PRACTICE The^Jjirftis feldom confiderable; the mouth is com- monly mdift; and as the difeafe advances, the tongue be- comes free from fur, appears very clean; and in the ad- vanced flages of the difeafe, the tongue and fauces appear to be fomewhat inflamed, and become more or lefs cover- ed with aphthae. As the difeafe advances, the red vfeffels of the adnata of the eye difappear, and the whole of the adnata becomes of a pearly white. The face is commonly pale; but, during the exacerba- tions, a florid red, and an almoft circumfcribed fpot, ap- pear on each cheek. For fome time, in the courfe of a heaic, the belly is bound; but, in the advanced ftages of it, a diarrhoea al- moft always comes on, and continues to recur frequently during the reft of the difeafe, alternating in fome meafurq with the fweatings mentioned above. The difeafe is always attended with a debility, which gradually increafes during the courfe of it. During the fame courfe an emaciation takes place, and goes to a greater degree than in almoft any other cafe. The falling off of the hairs, and the adunque form of the nails, are alfo fymptoms of the want of nourifhment. Towards the end of the difeafe, the feet are often affea- ed with cedematous fwellings. The exacerbations of the fever are feldom attended with any headach, and fcarcely ever with delirium. The fenfes and judgment commonly remain entire to the very end of the difeafe; and the mind, for the moll part, is confident and full of hope. Some days before death, a delirium comes on, and conw monly continues to the end. 860.] The heaic fever now defcribed (857, 858.) as accompanying a purulent ftate of the lungs, is perhaps the cafe in which it moft frequently appears: but I have never feen it in any cafe, when there was not evidently, or when I had not ground to fuppofe, there was a permanent puru- lency or ulceration in fome external or internal part. It was for this reafon that in (74.) I concluded it to be a fymptomatic fever only. Indeed, it appears to me to be always the effeft of an acrimony abforbed from abfeeffes or tilcersj althoughitis not equally the effeft of every fort OF PHYSIC. 29* of acrimony;, for the fcofbutic and cancerous kinds often fubfift long in the body without producing a heaic. What is theprecife ftate of the acrimony producing this I cannot determine, but it feGms to be chiefly that of a vitiated puru- lency. 861.] However this may be, it appears, that the heaic's depending in general upon an acrimony, explains ks pecu- liar circumftances. The febrile ftate feems to be chiefly an exacerbation of that frequency ofthe pulfe, which oc- curs twice every day to perfons in health, and may be pro- duced by acrimony alone. Thefe exacerbations, indeed, do not happen without the proper circumftances of py- rexia ; but the fpafm ofthe extreme veffels in a heaic does not feem to be fo confiderable as in other fevers: and hence the ftate of fweat and urine which appears fo early and fo conftantly in heaics. Upon the fame fuppofition of an acrimony corrupting the fluids, and debilitating the moving powers, I think that moft of the other fymptoms may alfo be explained. 86-2.] Having thus confidered the charaaeriftical fymp- toms and chkf part of the proximate caufe of the phthifis pulmonalis, I proceed to obferve, that an ulcer of the lungs, and ks concomitant circumftance of heaic fever, may arife from different previous affeaions ofthe lungs: all of which however may, in my opinion, be referred to five heads; that is, 1. To an hemoptyfis; 2. To a fuppu- ration of the lungs in confequence of pneumonia; 3. To catarrh; 4. Toafthma; or, 5. To a tubercle. Thefe fe- veral affections, as caufes of ulcers, fhall now be confi- dered in the order mentioned. 863.] It has been commonly fuppofed, that an hemop- tyfis was naturally, and almoft neceffarily, followed by an ulcer ofthe lungs:. but I will prefume to fay, that, in ge- neral, this is a miftake; for there have been many inftan- ces of hemoptyfis occafioned by external violence* without being followed by any ulcer of the lungs; and there have alfo been many inftances of hemoptyfis from an internal caufe, without any confequem ulceration. And this too has been the cafe, not only when the hemoptyfis happen- ed to young perfons, and recurred for feveral times, but wheri it has often recurred during the courfe of a long life. It is indeed eafy to conceive, that a rupture of the veffel* 30c PRACTICE of the lungs like that of the veffels of the nofe, may be often healed, as the furgeons fpeak, by the firft intention. It is probable therefore, that it is an hemoptyfis in parti- cular circumftances only, which is neceffarily followed by an ulcer; but what thefe circumftances are, it is difficult to determine. It is poffible, that merely the degree of rup- ture, or frequently repeated rupture preventing the wound from healing by the firft intention, may occafion an ulcer;- or it is poffible that red blood effufed, and not brought up entirely by coughing, may, by ftagnating in the bronchiae, become acrid, and erode the parts. Thefe however are but fuppofitions, not fupported by any clear evidence. And, if we confider that thofe cafes of hemoptyfis which follow the predifpofition (831.—834.) are thofe efpecially which end in phthifis, we fhall be led to lufpea that there are fome other circumftances which concur here to deter- mine the confequence of hemoptyfis, as I fhall hereafter endeavour to fliow. 864.] Any fuppofition,however,which we canmakewith refpc6t to the innocence of an hemoptyfis, muft not fuper- fede the meafures propofed aboye for its cure ; both be- caufe we cannot certainly forefee what may be the confe- quence of fuch an accident, and becaufe the meafures above fuggeftedare fafe ; for, upon every fuppofition, it is a di- athefis phlogiftica that may urge on every bad confequence to be apprehended. 865.] The fecond caufe of an ulceration ofthe lungs, to be confidered, is a fuppuration formed in confequence of pneumonia. 866.] From the fymptoms mentioned in ("857.—85S.) it may with reafon be concluded, that an abfcefs, or, as it is called, a vomica, is formed in fome part ofthe pleura, and moft frequently in that portion of it invefting the lungs. Here purulent matter frequently remains for fome time, as if enclofed in a cyft: but commonly it is not long be- fore it comes to be either abforbed, and transferred to fome other part of the body; or that it breaks through in-. to the cavity of the lungs, or into that of the thorax. In the latter cafe, it produces the difeafe called empyema ; but It is only when the matter is poured into the cavity of the bronchiae, that it properly conftitutes the phthifi.s pul- monalis. Jn the cafe of empyema, the chief circumftances *0F PHYSIC. 301 of the'phthifis are alfo prefer.r; but I fhall here confider that cafe only in which the abfcefs of the lungs gives occa- fion to a purulent expeaoration. 867.] An abfcefs of the lungs, in confequence of pneu- monia, is not always followed by a phthifis: for fome- times a hectic fever is not formed; the matter poured into the bronchia i> a proper and benign pus, which is fre- quently coughed up very readily, and fpitout: and, though this purulent expeaoration fhould continue for fome time, yet if a heaic does not come on, the ulcer foon heals, and every morbid fymptom difappears. This has happen- ed to frequently, that we may conclude, that neither the accefs of the air, nor the conftant motion of the lungs, will prevent an ulcer of thefe parts from healing, if the matter of it be well-conditioned. An abfcefs ofthe lungs, therefore, does not neceffarily produce the phthifis pul- monalis; and if it be followed by fuch a difeafe, it muft be in confequence of particular circumftances which cor- rupt the purulent matter produced, render it unfuitable to the healing of the ulcer, and at the fame time make it af- ford an acrimony, which, being abforbed, produces a heaic and its confequences. 868.] The corruption of the matter of fuch abfeeffes may be owing to feveral caufes, as, 1. That the matter effufed during the inflammation, had not been a pure fe- rum fit to be converted into a laudable pus, but had been united with other matters which prevented that, and gave a confiderable acrimony to the whole: Or, 2. That the matter effufed, and converted into pus, either merely by a long ftagnation in a vomica, or by its conneaion with an empyema, had been fo corrupted, as to'become unfit for the purpofe of pus in the healing of the ulcer. Thefe feem to be poffible caufes of the corruption of matter in abfeeffes, fo as to make it the occafion of phthifis in per- fons otherwife found; but it is probable, that a pneumonic abfcefs does efpecially produce phthifis when it happens to perfons previoufly difpofed to that difeafe, and therefore only as it concurs with fome other caufes of it. 869.] The third caufe fuppofed to produce phthifis, is a catarrh; which in many cafes feems in length of time to have the expectoration of mucus proper to it, gradually changed into an expedoration of pus; and at the fame time, 302 PRACTICE by the addition of a heaic fever, the difeafe, which was at firft a pure catarrh, is converted into a phthifis. Thitf fuppofition, however, is not eafily to be admitted. The catarrh is properly an affeaion of the mucus glands of the trachea and bronchize, analogous to the coryza, and lefe violent kinds of cynanche toniillaris, which very feldom terminate in fuppuration. And although a catarrh fhould be difpofed to fuch termination, yet the ulcer produced might readily heal up, as it does in the cafe of a cynanche tonfillaris ; and therefore fhould not produce a phthifis. 870] Further, the catarrh, as purely the effea of cold, is generally a mild difeafe, as well as of fhort duration; and ofthe numerous inftances of it, there are at moft but very few cafes which can be faid to have ended in phthifis. In all thofe cafes in which this feems to have happened, it is to me probable, that the perfons affeaed were pe'cufc arly predifpofed to phthifis. And the beginning of phthifis fo often refembles a catarrh, that the former may have been miftaken for the latter. Befides, to increafe the fal- lacy, it often happens that the application of cold, which is the moft frequent caufe of catarrh, is alfo frequently the exciting caufe of the cough which proves the begin* ning of phthifis. 871.] It is tome, therefore, probable, that a catarrh is very feldom the foundation of phthifis; but I would not pofitively affiert that it never is fo; for it is poffible that the cafes of a more violent catarrh may have joined with them a pneumonic 1ffeaion, which may end in a fuppura- tion; or it may happen that a long continued catarrh, by the violent agitation ofthe lungs in coughing will produce fome of thofe tubercles which are prefently to be menti- oned as the moft frequent caufe of phthifis. 872.] It muft be particularly obferved here, that no- thing faid in (871.) fhould allow us to negfea any appear- ance of catarrh, as is too frequently done; for it may be either the beginning of a phthifis, which is miftaken for a genuine catarrh, or that even as a catarrh continuing long* it may prdduee a phthifis, as in (871.) 873.] Many phyficians have fuppofed an acrimony of the fluids eroding fome ofthe veffels of the lungs, to be a frequent caufe of ulceration and phthifis. But this ap- pears to me to be a mere fuppofition: for in any of the in- OF PHYSIC. 303 Hances ofthe produ&ion of phthifis which I have feen, there was no evidence of any acrimony of the blood capa- ble of eroding the veffels. It is true, indeed, that in ma- ny cafes an acrimony fubfifting in fome part of the fluids, is the caufe of the difeafe; but it is at the fame time pro- bable, that this acrimony operates by producing tubercles, rather than by any direct erofion. 874.] It has been mentioned in (862.) that an afthma may be confidered as one ofthe caufes of phthifis; and by afthma I mean, that fpecies of it which has been commonly named the Spafmodic. This difeafe frequent- ly fubfifts very long without producing any other, and may have its own peculiar fatal termination, as fhall be explain- ed hereafter. But I have feen it frequently end in phthi- fis; and in fuch cafes I fuppofe it to operate in the man- ner above alledged of catarrh, that is, by producing tu- bercles, and their confequences, which fliall be prefently mentioned. 875.] I come now to confider the fifth head of the caufe of phthifis, and which I apprehend to be the moft frequent of any. This I have faid, in general, to be tu- bercles; by which terms arc meant, certain fmall tumours, which have the appearance of indurated glands. Diffec- tions have frequently fhown fuch tubercles formed in the lungs; and although at firft indolent, yet at length they become inflamed, and are thereby changed into little ab- feeffes, or vomica?, which breaking, and pouring their matter into the bronchia?, give a purulent expeaoration, and thus lay the foundation of phthifis. 876.] Though the matter expeaorated upon thefe oc- cafions has the appearance of pus, it is feldom that of a laudable kind; and, as the ulcers do not readily heal, but are attended with a heaic fever, for the moft part ending fatally, I prefume that the matter of the ulcers is imbued with a peculiarly obnoxious acrimony, which prevents their healing, and produces a phthifis in aH its circum- ftances, as mentioned above. 877.] It is very probable that the acrimony which thus difeovers itfelf in the ulcers, exifted before, and produced the tubercles themfelvcs; and it is to this acrimony that we muft trace up the caufe of the phthifis following thefe tubercles. This acrimony is probably, in different cafe»> 3? 4 PRACTICE of different kinds; and it will not be eafy to determine its varieties: but to a certain length I fhall attempt it. 878.] In one cafe, and that, too, a very frequent one, of phthifis, it appears, that the noxious acrimony is of the feme kind with that which prevails in the fcrophula. This may be concluded from obferving, that a phthifis, at its ufual periods, frequently attacks perfons born of feropbu- lous parents; that is, of parents who had been affeaed with fcorphula in their younger years: that very often, when the phthifis appears, there occur at the fame time fome lym- phatic tumours in the internal parts; and very often I have found the tabes mefenterica, which is a ferophulous affec- tion, joined with the phthifis pulmonalis. To all this I would add, that, even when no ferophulous affeaion has either manifeftly preceded or accompanied a phthifis, this laft however moft commonly affeas perfons of a habit re- fembling the ferophulous; that is, perfons of a fanguine, or of a fanguineo-melancholic temperament, who have very fine fkins, rofy complexions, large veins, foft flefh, and thick upper lip: and further, that in fuch perfons the phthi- fis comes on in the fame manner that it does in perfons having tubercles, as fliall be immediately explained. 879.] Another fpecies of acrimony producing tubercles of the lungs, and thereby phthifis, may be faid to be the exanthematic. Il is well known, that the fmall-pox fome- times, and more frequently meafies, lay the foundation of phthifis. It is probable alfo, that other exanthemata have the fame effea; and from the phenomena of the difeafe, and the diffeaions of perfons who have died of it, it is pro- bable, that all the exanthemata may occafion a phthifis, by affording a matter which in the firft place produces tubercles. 880.] Another acrimony, which feems fometimes to produce phthifis, is the fiphyiitic; but whether fuch an acrimony produces phthifis in any other perfons than the ,, previoufly difpofed, does not appear to me certain. 881 ] What other fpecies of acrimony, fuch as from * fcurvy, from pus abforbed from other parts ofthe body, from fuppreffed eruptions, or from other fources, may alfo produce tubercles and phthifis, I cannot now decide, but muft leave to be determined by thofe who have had experience of fuch cafes. 0FPHYS1C. 3C5 882.] There is one peculiar cafe of phthifis, which from my own experience I can take notice of. This is the cafe of phthifis from a calcareous matter formed in the lungs, and couched up, frequently with a little blood, fometimes with mucus only, and fometimes with pus. . How this matter is generated, or in what precife part of the lungs it is feated, I acknowledge myfelf ignorant. In three cafes of this kind which have occurred to me, there' was at the fame time no appearance of ftony or earthy concretions iri any other part of; he body. In one of thefe cafes, an cxqui- fittly formed phthfis came on, and proved mortal: While in the other two, the fymptoms of phthifis were never fully formed^ andafter fome time, merely by a milk diet and avoiding irritation, the patients entirely recovered. 883] Another foundation for phthifis, analogous, as I judge, to that of tubercles, is that which occurs to certain artificers whofe employment keep them almoft conftantly expofed to dull; fuch as ftone-cutters, millers, flax-dreffers, and fome others. I have not obferved in this country ma- ny inftances of phthifis which could be referred to^this \ caufe; but, from Ramazzini, Morgagni, and fome other writers, we muft conclude fuch cafes to be more fre- quent in the fouthern parts of Europe. 884.] Befides thefe now mentioned, there are probably fome other caufes producing tubercles, which have not yet been afcertained by obfervations; and it is likely, that in the ftate of tubercles there is a variety not yet accounted for; but all this muft be left to future obfervation and inquiry. 885.J It has been frequently fuppofed by phyficians, that the phthifis is a contagious difeafe; and I dare not af- fert that it never is fuch: but in many hundred inftances of the difeafe which I have feen, there has been hardly one which to me could appear to have arifen from contagion. It is poffible, that in warmer climates the effeas of conta- gion may be more difeernible. After having faid that a phthifis arifes from tubercles more frequently than from any other caufe, and after hav- ing attempted to affign the variety of thefe, I now proceed to mention the'peculiar circumftances and fymptoms which ufually accompany the coming on of the difeafe from tu-, bcrcles. Vol. I, Q <^ 3Q6 PRACTICE 886.] A tuberculous and purulent ftate. of tne mng' has been obferved in very young children, and in fome others at feveral different periods before the age of puber- ty and full growth; but inftances of this kind are rare: and the attack of phthifis, which we have reafon to impute to tubercles, ufually happens at the fame period which I have afiigned for the coming on of the hemoptyfis. 887.] The phthifis from tubercles does alfo generally affea the fame habits as the hemoptyfis, that is, perfons of a flender make, long necks, narrow chefts, and prominent fhoulders; but very frequently the perfons liable to tuber- cles have lefs of a florid countenance, and of the other marks of an exquifitely fanguinc temperament, than the perfons liable to hemoptyfis. ,n 888.] This difeafe, arifing from the tubercles, ufualjy commences with a flight and fhort cough, which, becoiaes habitual, is often little remarked by thofe affeaed, and fometimes fo little as to be abfolutely denied by them. At the fame time their breathing becomes eafily hurried by any bodily motion, their body grows leaner, and they be- come languid and indolent. This ftate fometimes con- tinues for a year, or even for two years, without the per- fons making any complaint of it, excepting only that they are affeaed by cold more readily than ufual, which fre- quently increafes their cough, and produces fome catarrh. This, again, however, is fometimes relieved; is fuppofed to have arifen from cold alone; and therefore gives no alarm either to the patient or to his friends, nor leads them to take any'precautions. 889.] Upon one or other of thefe occafions of catching cold, as we commonly fpeak, the cough becomes more con- fiderable; is particularly troublefome upon the patient's Jying down at night, and in this ftate continues longer than is ufual in the cafe of a fimple catarrh. This is more efpe- cially to call for attention, if the increafe and continuance^ of cough come on during the fummer feafon. 890.J The cough which comes on as in (888.) is very^ often for a long time without any expeaoration,; but when, from repeatedly catching cold, it becomes fiibre conftant, it is then at the fame time attended with fome expectora- tion, which is moft confiderable in the mornings. The matter of this expeaoration becomes by degrees more co- OF PHYSlt 507 pious, more vifcid, and more opaque; at length of a yel- low or greenifh colour, and of a purulent appearance. The whole ofthe fitter, however, is not always at once entirely changed in this manner; but, while one part of it retains the ufual form of mucus, another fuffers the changes now defcribed. 891.] When the cough increafes, and continues very frequent through the night, and when the matter expeao- ratcd undergoes the changes I have mentioned, ihe breath: ing at the fame time becomes more difficult, and the ema- ciation and weaknefs go on alfo increafing. In the female fex, as the difeafe advances, and fometimes early in its progrefs, the menfes ceafes to flow; and this circumftance is to be confidered as commonly the effea, although the fex themfelves are ready to believe it the fole caufe of the dif- eafe. 892.] When the cough comes on as in (888.) the pulfe is often natural, and for fome time after continues to be fo; but the fymptoms have feldom fubfifted long before the pulfe becomes frequent, .and fometimes to a considera- ble degree, without much ofthe other fymptoms of fever. At length, however, evening exacerbations become re- markable; and by degrees the fever affumes the exquisite form of heaic, as'defcribed in (847—859.) 893.] It is feldom that the cough, expeaoration, and fever, go on increasing, in the manner now defcribed, without fome pain being felt in fome part of the thorax. It is ufually and moft frequently felt at firft under the fter- num, and that efpecially, or almoft only, upon occasion of coughing; but very oaen, and that too, early in the courfe ofthe difeafe, a pain is felt on one side, fometimes very conftantly, and fo as to prevent the>crfon from lying easily upon that side: but at other times the pain is'felt only upon a full infpiration, or upon coughing. Even when no pain is felt, it generally happens that phthisical perfons cannot lie easily on ft^ne one of their fides, with- out having^their difficulty of breathing increafed, and their cough excited. 894.] The phthisis begins, and fometimes proceeds to its fatal iffuc, in the manner defcribed from (888, to 894.) without any appearance of hemoptyfis. Such cafe> are indeed rare; bur it is very common for the difeafe to ad. *<>« PRACTICE vance far, and even to an evident purulcncy aad heaic ftate, without any appearance of blood in the fpitting : fo that it may be affirmed, the difeafe is frequency not founded in he- moptysis. At the fame time, we muff allow, not only that it fometimes begins with an hemoptysis, as it is faid in (863.) but further, that it feldom happens that in the progrefs of the difeafe more or lefs of an hemoptysis does not appear. Some degree of blood-fpitting does, indeed, appear fome- times in the ftate mentioned (888. 892.) but more com- monly in the more advanced ftages of the difeafe only, and particularly upon the firft appearance of purulency. How- ever this may be, it is feldom, in the phthisis from tuber- cles, that the hemoptysis is considerable, or requires any re- medies different from thofe which are otherwife neceffary for the ftate of the tubercles. 895.] I have now defcribed a fucceflion of fymptoms which, in different cafes, occupy more or lefs time. In this climate they'very often take up fome year*, the fymp- ; toms appearing efpecially in the winter and fpring, com- monly becoming eafier, and fometimes almoft difappear- ing, during the fummer: but returning again in winter, they at length after two or three years, prove fatal, to-% ' waids the end of fpring or the beginning of fummer. 896.] In this difeafe, the prognofis is for the moft part unfavourable. Of thofe affeaed with it, the greater num- ber die; but there are alfo many of them who recover en- tirely, after having been in very unpromifing circumftan- ces. What are, however, the circumftances more certain- ly determining to a happy or to a fatal event, I have not yet been able to afcertain. 897.] The following aphorifms are the refult of my ob- fervations. A phthifis pulmonalis from hemoptyfis, is more fre- quently recovered than one from tubercles. An hemoptyfis not only is not always followed by a phthifis, as we have faid above (863.) but even when fol- -T lowed by an ulceration, the ulceration is fometimes attend- . ed with little of heaic, and frequently admits of being foon healed. Even when hemoptyfis and ulceration have hap- pened to be repeated, there are inftances of perfons reco- • vering entirely after feveral fuch repetitions! A phthifis from a fuppuration in confequence of pneu- __________________________________■________*lr;____________ OF PHY SIC £09 monic inflammation, is that which moft rarely occurs in this climate; and a phthifis does not always follow fuch fuppuration, when the abfcefs formed foon breaks and dif- charges a laudable pus; but, if the abfcefs continues long lhut up, and till after a confiderable degree of heaic has been formed, a phthifis is then produced, equally danger- ou . as that from other caufes. A phthifis from tubercles has, I think, been recovered: but it isof all others the moft dangerous; and, when arifing from a hereditary taint almoft certainly fatal. The danger of a phthifis, from whatever caufe it may have arifen, is moft certainly to be judged of by the de- gree to which the he£tic and its confcquences have arrived. From a certain degree of emaciation, debility, profufe fweatiiv,, and diarrhcea, no perfon recovers. A mania coming on, has been found to remove all the fymptoms, and fometimes has entirely cured the difeafe; but, in other cafes, upon going off of the mania, the phthi- fis has recurred, and proved fatal. The pregnancy of women has often retarded the progrefs of a phthifis; but commonly it is only till after delivery, when the fymptoms of phthifis return with violence3 and foon prove fatal. Sect. II. Of the Cure of Phthisis. 898.] FROM what has been juft now faid, it will readily appear, that the cure ofthe phthifis pulmonalis muft be exceedingly difficult; and that even the utmoft care and attention in the employment of remedies, have feldom fucceeded. It may be doubtful whether this failure is to be imputed to the imperfeaion of our art, or to the abfo-i lutely incurable nature of the difeafe. I am extremely averfe in any cafe to admit of the latter fuppofition, and can always readily allow of the former; but, in the mean time, mull mention here, what has been attempted towards either curing or moderating the violence of the difeafe. 899.] It muft be obvious, that according to the differ- ent circumftances of'this difeafe, the method of cure muft be different. Our firft attention ihould be employed in Sid PRACTICE watching the approach of the difeafe, and preventing its proceeding to an incurable ftate. In all perfons of a phthifical habit, and efpecially in thofe born of phthifical parents, the fiighteft fymptoms of the approach of phthifis, at the phthifical period of life, ought to be attended to.* 900.] When an hemoptyfis occurs, though it be not always followed with ulceration and phthifis, thefe how- ever are always to be apprehended; and every precaution is to be taken a.gainft them. This is efpecially to be done by employing every means of moderating the hemorrhagy, and of preventing its return, direaed in (891.) et seq. and thefe precautions ought to be continued for feveral years after the occurrence ofthe hemoptyfis. 901.] The phthifis which follows a fuppuration from pneumonic inflammation, can only be prevented with cer- tainty, by obtaining a refolution of fuch inflammation. What may be attempted towards the cure of an abfcefs and ulcer which have taken place, I fhall fpeak of hereafter. 902.] I have faid, it is doubtful if a genuine catarrh ever produces a phthifis; but have allowed that it poffibly may: and both upon this account, and upon account of the ambiguity which may arife, whether the appearing ca- tarrh be a primary difeafe, or the effea of a tubercle, I confider it as of confequence to cure a catarrh as foon as *poffible after its firft appearance. More efpecially when it fhall linger, and continue for fome time, or fhall, after fome intermiffion, frequently return, the cure of it fhould be diligently attempted. The meafures requifite for this purpofe fhall be mentioned afterwards, when we come to treat of catarrh as a primary difeafe; but, in the mean time, the means neceffary for preventing its producing a phthifis fhall be mentioned immediately, as they are the fame with thofe I fhall point out as neceffary for preventing a phthifis from tubercles. 903.] The preventing of a phthifis from afthma muft: be by curing, if poffible, the afthma, or at leaftVby mode- rating it as much as may be done: and as it is probable that afthma occafions phthifis, by producing tubercles, the mea- * This early attention to the nrft fymptoms ofthe difeafe is ofthe mmoftcon-* fequence, for it is only in the early ftage that any remedies can be employed with fuccefs, as experience has fufficiently taught. Sec Article 905. et fe^. OF PHY SIC. 3H fures neceffary for preventing phthifis from afthma, will be the fame with thofe neceffary in the cafe of tubercles, which I am now about to mention. r 904.] I confider tubercles as by much the moft frequent caufe of phthifis; and even in many cafes where this feems to depend upon hemoptyfis, catarrh, or afthma, it does however truly arife from tubercles. It is upon this fub- jea, therefore, that I fhall have occafion to treat of the meafures moft commonly requifite for curing phthifis. 905.] When, in a perfon born of phthifical parents, of a phthifical habit, at the phthifical period of life, the fympr toins (888.) in the fpring, or the beginning of fummer,' fhall appear in the fiighteft degree, we may prefume that a tubercle, or tubercles, either have been formed, or are forming in the lungs; and therefore, that every means we can devife for preventing their formation, or for procuring their refolution, fliould be employed immediately, even ahhough the patient himfelf fhould overlook or negfea the fymptoms, as imputing them to accidental cold. 906.] This is certainly the general indication; but how it may be executed, I cannot readily fay. I do not know that, at any time, phyficians have propofed any remedy capable of preventing the formation ofthe tubercles, or of rcfolving them when formed. The analogy of fcrophula, gives no aflifiance in this matter. In fcrophula the reme- dies that are feemingly of moft power, are, fea-water, or certain mineral waters; but thefe have generally proved hurtful in the cafe of tubercles of the lungs. I have known feveral inftances of mercury very fully employed for cer- tain difeafes, in perfons who were fuppofed at the time to have tubercles formed, or forming, in their lungs; but though the mercury proved a cure for thofe other difeafes, it was of no fervice in preventing phthifis, and in fome cafes feemed to hurry it on. 907.] Such appears to me to be the prefent ftate of our art, with refpea to tlie cure of tubercles; but I do not def- pair of a remedy for the purpofe being found hereafter. In the mean time, all that at prefent feems to be within the reach of our art, is to take the meafures proper for avoidr ing the inflammation of tubercles. It is probable that tu- bercles may fublift long without producing any diforder; and I am difpofed to think, that nature fometimes refolyes 3!2 PRACTICE and difeuffes tubercles which have been formed; and that nature does this only when the tubercles remain in an un- inflamed ftate; and therefore, that the meafures neceffary to be taken, are chiefly thofe for avoiding the inflamma- tion of the tubercles. 908] The inflammation of a tubercle ofthe lungs is to be avoided upon the general plan of avoiding inflamma- tion, by blood-letting, and by an antiphlogiftic regimen; the chief part of which, in this cafe, is the ufe of a low diet. This fuppofes a total abftinence from animal food, and the ufing of vegetable food almoft alone: but it has been found, that it is not neceffary for the patient to be confin- ed to vegetables of the weakeft nourifhment, it being fuffi- cient that the farinacea be employed, and together with thefe, milk. 909.J Milk has been generally confidered as the chief remedy in the phthifis, and in the cafe of every tendency to it; but whether from its peculiar qualities, or from its being of a lower quality, with refpea to nourifhment, than any food entirely animal, is not certainly determined. The choice and adminiftration of milk will be properly di- rected, by considering the nature ofthe milk of the feve- ral animals from which it may be taken, and the particular ftate of the patient with refpea to the period and circum- ftances ofthe difeafe, and to the habits of his ftomach with refpea to milk. 910.] A fecond means of preventing the inflammation ofthe tubercles ofthe lungs, is, by avoiding any particu- lar irritation ofthe affeaed part, which may arife from any violent exercife of refpiration; from any confiderable de- gree of bodily exercife; from any pofition of the body, which ftraitens the capacity of the thorax; and laftly, from cold applied to the furface of the body, which determines the blood in greater quantity to the internal parts, and par- ticularly to the lungs. 911.] From the laft-mentioned confideration, the ap- plication of cold in general, and therefore the winter-fea- fon, in cold climates, as diminifhing the cutaneous per- fpiration, is to be avoided; but more particularly, that ap- plication of cold is to be fhunned that may fupprefs per- fpiration, to the degree of occafioning a catarrh, which confifts in an inflammatory determination to the lungs? and O F P H Y 3 I C. 313 may therefore m^ft certainly produce an inflammation of the t ubercles there. By confidering, that the avoiding heat is a part of the antiphlogiftic regimen above recommended, and by compar- ing this with what has been juft now laid refpeaing the avoiding cold, the proper choice of climates and feafons for phthifical patients will be readily underftood. 912.] A third means of avoiding the inflammation of the tubercles ofthe lungs confifts, in diminifhing the de- termination of the blood to the lungs, by fupporting and increafing the determination to the furface of the body; which is to be chiefly and moft fafely done by warm cloth- ing,* and the frequent ufe of the exercifes of geftation. 913.] Every mode of geftation has been found of ufe in the phthifical cafes; but riding on horfeback, as being accompanied with a great deal of bodily exercife, is lefs fafe in perfons liable to an hemoptyfis. Travelling in a carriage unlefs upon very fmooth roads may alfo be of doubtful effea; and all the modes of geftation that are em- ployed on land, may fall fhort of the effeas expeaed from them, becaufe they cannot be rendered fufficiently con- ftant ; and therefore it is that failing, of all other modes of geftation, is the moft effeaual in pneumonic cafes, as be- ing both the fmoothefl and moft conftant. It has been imagined, that fome benefit is derived from the ftate of the atmofphere upon the fea; but I cannot find that any impregnation of this which can be fuppofed to take place, can be of fervice to phthifical perfons. It is however piobable, that frequently fome benefit may be derived from the more moderate temperature and greater purity of the air upon the fea. 914.] In order to take off any inflammatory determi- nation of the blood into the veffels of the lungs, blifters ap- plied to fome part of the thorax may often be of feFvice; and for the fame purpofe, as well as for moderating the general inflammatory ftate ofthe body, iffues of various kinds may be employed with advantage. • This is a moft effential part in the cure of phthifis, and many other defea- ts prevalent in cold climates. The warm clothing that is moft effe&ual is flannel fliirts next the fkin. It frels a little difagrecable at firft to a perfon unaccuftomed to it; but the great relief it affords, and the comfortable fenfation it produces, are fo ftrong in- ducements for continuing its ufe, that few people who have once experienced its beneficial effects have any defire torelinquiih it. Vol. I. R r 311 PRACTICE 915.] The feveral meafures to be purfued in the cafe of what is properly called an Incipient Phthisis, have now been mentioned; but they have feldom been employed in fuch cafes in due time, and have therefore, perhaps, feldom proved effectual. It has more commonly happen- ed, that after fome time, an inflammation has come upon the tubercles, and an abfcefs has been formed, which open- ing into the cavity ofthe bronchiae, has produced an ulcer, and a confirmed phthisis. 916.] In this ftate of matters, fome new indications dif- ferent from the former may be fuppofed to arife, and in- dications for preventing abforption, for preventing the ef- feas of the abforbed matter upon the blood, and for heal- ing the ulcer, have been aaually propofed. I cannot find, however, that any of the means propofed for executing thefe indications, are either probable or have proved effec- tual. If, upon fome occasions, they have appeared to be ufeful,'it-has been probably by anfwering fome other in- -tention. While no antidote againft the poifon which efpecially operates here, feems to have been as yet found out, it ap- pears to me, that too great a degree of inflammation has a great fliare in preventing the healing of the ulcers which occurs; and fuch inflammation is certainly what has a great fhare in urging on its fatal confcquences. The only prac- tice, therefore, which I can venture to propofe, is the fame in the ulcerated as in the crude ftate of a tubercle; that is, the employment of means for moderating inflammation, which have been already mentioned (908. et seq.) 917. J The bal famics whether natural or artificial, which have been fo commonly advifed in cafes of phthisis, ap- pear to me to have been propofed upon no fufficient grounds, and to have'proved commonly hurtful. The re- sinous and acrid fubftance of myrrh, lately recommended, has not appeared to me to be of any fervice, and in fome cafes to have proved hurtful.* 918.] Mercury, fo often ufeful in healing ulcers, has been fpecioufly enough propofed in this difeafe; but whe- ther that it be not adapted to the particular nature of the * From the preceeding account of the difeafe, it is fufliciently evident that all acrid and hot fubftances mull be hurtful in phthifis.

Upon many trials which I have feen made, it has proved of no fervice, and commonly has appeared to be manifeft- ly pernicious. 919.] The Peruvian bark has been recommended for fe-i veral purpofes in phthifical cafes; and it is faid, upon fome occafions to have been ufeful ; but I have feldom found it to be fo ; and as by its tonic power it increafes the phlogiftic diathefis of the fyftem, I have frequently found it hurtful. In fome cafes, where the morning re- miffions ofthe fever were confiderable, and the noon exa- cerbations well marked, I have obferved the Peruvian bark given in large quantities, have the effect of flopping thefe exacerbations, and at the fame time of relieving the whole ofthe phthifical fymptoms : but in the cafes in which I ob- ferved this, the fever fliowed a conftant tendency to recur; and at length the phthifical fymptoms alfo returned, and proved (juickly fatal. 920.] Acids of all kinds, as antifeptic and refrigerant, are ufeful in cafes of phthisis ; but the native acid, of vege- tables* is more ufeful than the foffil acids, as it.can be gi- ven in much larger quantities, and may alfo be given more fafely than vinegar, being lefs liable to excite coughing. • 921.] Though our art can-do fo little towards the cure of this difeafe, we muft, however, palliate the uneafy fymp- toms of it as well as we can. The fymptoms efpecially urgent arc the cough and diarrhoea. The cough may be in fome meafure relieved by demulcents, (872.) but the re- lief obtained by thefe is imperfea and transitory, and very often the ftomach is difturbed by the quantity of oily, mu- cilaginous, and fweeU fubftances, which are on thefe occa- sions taken into it. 922.] The only certain means of relieving the cough, is by employing opiates. Thefe, indeed, certainly in- creafe the phlogiftic diathefis of the fyftem; butcommonly they do not fo much harm in this way, as they do fervice by quieting the cough, and giving fleep. They are fup- * The acid fruits, acid of tartar, acid of forrel, and other plants yielding an acid but not an acrid, juice.

In the advanced ftate of the difeafe, opiates feem to increafe the fweatings that occur; but they compenfate this, by the eafe they afford in a difeafe which cannot be cured. 923.] The diarrhoea which happens in the advanced ftate of this difeafe, is to be palliated by moderate aftrin- gents, mucilages, and opiates. Rhubarb, fo commonly prefcribed in every diarrhoea, and all other purgatives, are extremely dangerous in the colliquative diarrhoea of hettics. Frefh fubacid fruits, fuppofed to be always laxative, are often in the diarrhoea of hectics, by their antifeptic quality, very ufeful. CHAP.

Ofthe Phenomena and Causes of the Hemorrhois. 924.] XX DISCHARGE of blood from fmall tumours on the verge of the anus, is the fymptom which generally conftitutes the Hemorrhois; or, as it is vulgaily called, the Hemorrhoidal Flux. But a difcharge of blood from within the anus, when the blood is of a florid colour, fhow- ing it to have come from no great diftance, is alfo confi. deredasthe fame difeafe; and phyficians have agreed in making two cafes or varieties of it, under the names of External and Internal Hemorrhois. 926.] In both cafes it is fuppofed that the flow of blood is from tumours previously formed, which are named He- morrhoids, or piles ; and it frequently happens, that the tumours exift without any difcharge of blood; in which cafe,however, they are fuppofed to be a part of the fame difeafe, and are named Hemorrhoides Caecae,6r Blind Piles. 926.] Thefe tumours, as they appear without the anus, are fometimes feparate, round, and prominent, on the verge of the anus; but frequently the tumour is only one tumid ring, forming, as it were, the anus pufhed without the body. OF PHY SIC. 31T 927.] Thefe tumours, and the difcharge of blood from them, fometimes come on as an affeaion purely topical, and without any previous diforder .in other parts ofthe bo- dy : but it frequently happens, even before the tumours are formed, and more efpecially before the blood flows, that various diforders are felt in different parts ofthe body, as headach, vertigo, ftupor, difficulty of breathing, fick- nefs, cholic-pains, pain of the back and loins; and often, together with more or fewer of thefe fymptoms, there oc- curs a confiderable degree of pyrexia. The coming on of the difeafe with thefe fymptoms, is ufually attended with a fenfe of fullnefs, heat, itching, and pain in and about the anus. Sometimes the difeafe is preceded by a difcharge of fe- rous matter from the anus: and fometimes this ferous dif- charge, accompanied with fome fwelling, feems to be in place of the difcharge of blood, and to relieve thole dif- orders of the fyftem which we have mentioned. This fe- rous difcharge, therefore, has been named the Hemorr- hois Alba. 928.] In the hemorrhois, the quantity of blood difcharg- ed is different upon different occafions. Sometimes the blood flows only upon the perfons going to ftool; and com- monly, in larger or lelfer quantity, follows the difcharge of the faeces. In other cafes, the blood flows widiout any difcharge o^ fasces; and then, generally, it is after havmg been preceedcd by the diforders above mentioned, when it is alfo commonly in larger quantity. This difcharge of blood is often very confiderable; and, by the repetition, it is often fo great, as we could hardly fuppofe the body to bear but with the hazard of life. Indeed, though rarely, it has been fo great as to prove fuddenly fatal. Thefe con- fiderable difcharges occur efpecially to perfons who have been frequently liable to the difeafe. They often induce great debility ; and frequently a leucophlegmatia, or drop- fy, which proves fatal. The tumours and difcharges of blood in tljis difeafe, . often recur at exaaiy ftated periods. 929.] It often happens, in the decline of life, that the hemorrhoidal flux, formerly frequent, ceafes to flow; and,. upon that event, it generally happens that the perfons are affeaed with apoplexy or palfy. 318 PRACTICE 930.] Sometimes hemorrhoidal tumours are affeaed* with confiderable inflammation; which, ending in fuppu- ration, gives occafion to the formation of hftulous ulcers in thofe parts. 931.] The hemorrhoidal tumours have been often con- fidered as varicous tumours, or dilatations of veins; and it is true, that in fome cafes varicous dilatations have ap- peared upon diffettion. Thefe, however, do not always appear; and I prefume it is not the ordinary cafe, but that the tumours are formed by an effufion of blood into the cellular texture of the inteftine near to its extremity. Thefe tumours, efpecially when recently formed, frequent*. ly contain fluid blood; but, after they have remained for fome time, they are commonly of a firmer fubftance. 932.] From a confideration of their caufes, to be here- after mentioned, it is fufficiently probable, that hemorrhoi- dal tumours are produced by fome interruption of the free return of blood from the veins of the lower extremity of the reaum; and it is poffible, that a confiderable accumu- lation of blood in thofe veins, may occafion a rupture of their extremities, and thus produce the hemorrhagy or tu- mours I have mentioned. But, confidering that the he- morrhagy occurring here is often preceded by pain, in- flammation, and a febrile ftate, as well as by many other fymptoms which fhow a connection between the topical af- feaion and the ftate of the whole fyftem, it feems probable that the interruption of the venous blood, which we have fuppofed to take place, operates in the manner explained in (768.) and therefore, that the difcharge of blood here is commonly from arteries. 933-] Some phyficians have been of opinion, that a difference in the nature of the hemorrhois, and of its effeas upon the fyftem, might arife from the difference of the he- morrhoidal veffels from which the blood iffued. But it appears to me, that hardly in any cafe we can diftinguifh the veffels from w7hich the blood flows; and that the fre- quent inofculations, of both the arteries and veins which belong to the lower extremity of the reaum, will render the effeas of the hemorrhagy nearly the fame, from which- foever of thefe veffels the blood proceed. 934-] In (768.) * have endeavoured to explain the man- ner in which a certain ftate of the fanguiferous fyftem mi«»— £Df t&e Leucorr&oea, jFiuor $ftu3, cr eobite*. 984.] JtLiVERY ferous or puriform difcharge from the vagina, may be, and has been comprehended under one or other of the appellations I have prefixed to this chapter.

From the leucorrhcea not having appeared foon after communi- cation with a perfon who might be fufpected of communi- cating infection, and from the firft appearance of the dif- eafe not being accompanied with any inflammatory affec- tion of the pudenda.* 986.] The appearance of the matter difcharged in the leucorrhcea, is very various with refpect to confiitence and colour; but from thefe appearances, it is not always poflt- ble to determine concerning its nature, or the particular fource from whence it proceeds. 987. J The leucorrhcea, of which I am to treat, as afcer- tained by the feveral circumftances (985.) feems to proceed from the fame caufes as that Ipecies of menorrhagia which I fuppofe to arife from the laxity of the extreme veffels of the uterus. It accordingly often follows or accompa- nies fuch a menorrhagia; but though the leucorrhcea de- pends chiefly upon the laxity mentioned, it may have pro- ceeded from irritations inducing that laxity, and feems to be always increafed by any irritations applied to the uterus. 988. J Some authors have alleged, that a variety of cir- cumftances in other parts of the body may have a fliare in * Nothing is more frequent with ignorant practitioners than to miftake a gonorrhea for a leucorrhcea. Women in general give the name of whites to a gonorrhoea, and therefore the unwary practitioner may the more eafily be milled. The diilinguifiiing character!

The other diftinguifiiing marks of a gonorrh ia are, fmarting in making water, itching of the pndrnda, increafed inclination for venery, a fwelling of the labia and ofthe glands about th« groin. Some anthers mention the color of the dif- charged matter as a dilunguifhing mark; thii, however, is inconftant. IS PRACTICE bringing on and in continuing this affection of the uterus now under confideration; but I cannot difcover the reali- ty of thofe caufes; and it feems to me, that this leucor- rhcea, excepting in fo far as it depends upon a general de- bility ofthe fyftem, is always primarily an afftclion ofthe uterus; and the affections of other parts of the body which may happen to accompany it, are for the moft part to be confidered as effects, rather than as caufes. 989.] The effects of the leucorrhcea arc much the fame with thofe of menorrhagia : inducing a general debility, * and in particular, a debility in the functions ofthe ftomach. If, however, the leucorrhcea be moderate, and be not ac- companied with any confiderable degree of menorrhagia, it may often continue long without inducing any great de- gree of debility, and it is only when the difcharge has been very copious as wrell as conftant, that its effects in that way 1 are very remarkable. • 990.] But, even when its effects upon the whole body are not very confiderable, it may ftill be fuppofed to weaken the -genital fyftem; and it feems fufficiently probable that this difcharge may often have a fhare in occafioning barrennefs. 991. J The matter difcharged in the leucorrhcea, is at firft generally mild; but after fome continuance of the dif- eafe, it fometimes becomes acrid;* and by irritating, or perhaps eroding, the furfaces over which it pafies, induces various painful diforders. 992.] As I have fuppofed that the leucorrhcea proceeds from the fame caufes as that fpecies of menorrhagia which is chiefly owing to a laxity of the uterine veffels, it muft be treated, and the cure attempted, by the fame means as delivered in (981.) for the cure of menorrhagia, and with ' lefs referve in refpect of the ufe of aftringents.t * The young practitioner muft not conclude toohaftily that an ulcer exifts ^ in the uterus when the matter difcharged is acrid.—Practice has offered ma- ny inftances where the matter has excoriated the pudenda, and yet no ulcer a cxifted. f The electuary mentioned at the end of the laft note on Article 982, hat JJ been found very efficacious in fome cafes of leucorrhoea.—Its dofe may be j J increafed to a drachm tfirice a-day, either fwallowed as a bolus, or diffolved IkVl in an ounce of pure water, and half an ounce of pure cinnamon-water.

The former I fuppofe to be the moft ufual caufe of retention, the latter the moft common caufe of fuppreffion; and of each of thefe I fhall now treat more par- ticularly. 997-J The retention ofthe menfes, the emansio emensium of Latin writers, is not to be confidered as a difeafe mere- ly from the menfes not flowing at that period which is ufual w7ith molt-other women. • This period is fo different in dif- ferent women, that no time can be precifely afligned as proper to the fex in general.—In this climate, the menfes ufually appear about the age of fourteen; but in many they appear more early, and in many not till the fixteenth year: in which laft cafe it is often without any diforder be- ing thereby occafioned. It is not therefore from the age of the perfon that the retention is to be confidered as a dif- eafe; and it is only to be confidered as fuch, when about the time the menfes ufually appear, fome diforders arife in other rJarts of the body which may be imputed to their retention; being fuch as, when arifing at this period, are known from experience to be removed by the flowing of the menfes. 998.] Thefe diforders are, a fluggifhnefs, and frequent fenfe of laffitude and debility, with various fymptoms of dyfpepfia; and fometimes with a preternatural appetite.* At the fame time the face lofes its vivid colour, becomes pale, and fometimes of a yellowifh hue; the whole body becomes pale and flaccid; and the feet, and perhaps alfo a great part of the body, become affected with cedematous fwelling. The breathing is hurried by any quick or labo- rious motion of the body and the heart is liable to palpita- tion and fyncope.—A headach fometimes occurs; but more certainly pains of the back, loins, and haunches.t * This is a very extraordinary fymptom, which has not hitherto been ex« plained. It fometimes accompanies every ceffation of the uterine difcharge, but frequently appears in the moft violent degree in pregnancy. In young women, the appetite for chalk, lime, rubbim, charcoal, and various abforbents, is the moft prevalent. Stahl, and his followers, made great ufe of this cir- Ctimftance in fupporting their favourite opinion of the vis medicatrix naturx. \ Thefe pains are not properly fymptoms of the difeafe, but prognoftic* of OF PHYSIC. 15 999-] Thefe fymptoms, when occurring in a high de- gree, conftitute the chlorosis of authors, hardly ever ap- pearing feparate from the retention of the menfes; and, attending to thefe fymptoms, the caufe of this retention may, I think, be perceived. Thefe fymptoms manifeftly fhow a confiderable laxity and flaccidity ofthe whole fyftem; and therefore give rea- fon to conclude, that the retention of the menfes accom- panying them, is owing to a weaker action of the veffels of the uterus; which therefore do not impel the blood into their extremities with a force fufficient to open thefe, and pour out blood by them. 1000.J How it happens that at a certain period of life a flaccidity of the fyftem arifes in young women not ori- ginally affected with any fuch weaknefs or laxity, and of which but a little time before, they had given no indication, may be difficult to explain; but I would attempt it in this way. As a certain ftate of the ovaria in females, prepares and difpofes them to the exercife of venery, about the very period at which the menfes firft appear, it is to be prefum- ed, that the ftate of the ovaria and that of the uterine vef- fels are in fome meafure connected together; an<5 as gener- ally fymptoms of a change in the ftate of the former appear before thofe of the latter, it may be inferred that the ftate of the ovaria has a great fhare in exciting the aftion of the uterine veffels and producing the menftrual flux. But analogous to what happens in the male fex, it may be pre- fumed, that in females a certain ftate of the genitals is ne- ceffary to gire tone and tenfion to the whole fyftem; and therefore that, if the ftimulus.arifing from the genitals be wanting, the whole fyftem may fall into a torpid and flac- cid ftate, and from thence the chlorofis and retention o£ the menfes may arife. 1001.J It appears to me, therefore, that the retention1 of the menfes is to be referred to a certain itate or affection of the ovaria: but what is precifely the nature of this af- fection, or what are the caufes of it, I will not pretend to explain; nor can I explain in what manner that primary caufe of rctentipn is to be removed. In this, therefore,. the efforts nature male;; to remove, the difeafe.; They are fymptoms ofthe vis medicatrix. u PRACTICE as in many other cafes, where we cannot affign the proxi- mate caufe of difeafes, our indications of cure muft be formed for obviating and removing the morbid effects or fymptoms which appear. 1002.] The effects, as has been faid in (999.) confift in a general flaccidity of the fyftem, and confequently in a weaker action of the veffels of the uterus; fo that this de- bility may be confidered as the more immediate caufe of the retention. This therefore, is to be cured by reftoring the tone of the fyftem in general, and by exciting the ac- tion of the uterine veffels in particular. 1003.] The tone of the fyftem in general is to be reftor- ed by exercife, and in the beginning ofthe difeafe, by cold bathing. At the fame time, tonic medicines* may be em- ployed; and of thefe the chalybeates have been chiefly recommended. 1004.] The action of the veffels ofthe uterus may be excited : ill, By determining the blood into them more copiouf- ly ; which is to be done by determining the blood into the defcending aorta, by purging, by the exercife of walking,t by friction, and by warm bathing ofthe lower extremities. It is alfo probable that the blood may be determined more copioufly into the hypogastric arteries which go to the ute- rus, by a compreffion of the iliacs ; but the trials of this kind hitherto made have feldom fucceeded. 1005.] 2^y? The action of the uterine veffels may he excited by ftimulants applied to them. Thus thofe purga- tives which particularly ftimulate the inteftinum rectum,* * Forms of the tonic medicines have been given in fome of the preceding notes. The electuary in the note on article 9S2. is frequently ufed with fuc- cefs.- In this cafe, we muft not ufe aftringents, but tonics, and confequently only fuch tonics as are not aftringents, at leaft in a high degree. The fimple bitter tonics frequently anfwer where the fymptoms are not fevere. The in- fufum gentianae compofitum of the new London Pharmacopoeia is a good for- mula. The dofe of it is two ounces twice a day, or oftener, if the ftomadl can bear it. Chalybeates are abfolutely neceffary if the difeafe withftands the ufe of bitters ; they may be given in any of the forms mentioned in the preceding notes. t Dancing is alfo a proper exercife in this difeafe. | The ftimulant purges are in general the drafticrefins, as Scammony, Aloes. &c. Various formulx of them have been recommended in thefe cafes ; the pilul* Rufi is commonly ufed with good effect. It may be given in the quan- tity of half a drachm, or, in ftrong conftitutions, two fcruples. It ought not tobe repeated above twice a week; and, in the intermediate days, we may employ the tonic medicines above mentioned. The Filulaeecphraeticae ofthe, Edinburgh Pharmacopoeia is another very effectual medicine iu thefe cafes, O F ft H Y S I C. 17 may alfo prove ftimulant to the uterine veffels connected with thofe of the rectum. The exercife of venery cer- tainly proves a ftimulus to the veffels of the uterus; and therefore may be ufeful when, with propriety, it can be employed. The various medicines recommended as fti- mulants of the uterine veffels, under the title of Emmena- gogues, have never appeared to me to be effectual; and I cannot perceive that any of them are poffefled of a fpecific power in this refpe6t. Mercury, as an univerfal ftimulant, may act upon the uterus, but cannot be very lately em- ployed in chloiotic perfons. One of the moft powerful means of exciting the action of the veffels in every part of the fyftem is, the electrical fhock; and it has often been employed with fuccefs for exciting the veflels ofthe uterus. 1006.J The remedies (1002—1005.) now mentioned, are thofe adapted to the retention of the menfes; and I am next to confider the cafe of suppression. In entering upoa this, I muft obferve, that every interruption of the flux, after it has once taken place, is not to be confidered as a cafe of fuppreffion. For the flux, upon its firft appear- ance, is not always immediately eftablifhed in its regular courfe; and therefore, if an interruption happen foon after the firft appearance, or even in the courfe of the firft, or perhaps fecond year after, it may often be confidered as a cafe of retention, efpecially when the difeafe appears with the fymptoms peculiar to that ftate. 1007.] Thofe which may be properly confidered as cafes of fuppreffion, are fuch as occur after the flux has been for fome time eftablifhed in its regular courfe, and in Its dofe is half a drachm twice a week, if we intend to purge brifkly, but, 07 giving a fmaller quantity, as ten, twelve, or fifteen grains Once a-day, a com- ftant ftimulus is preferved, which fome practitioners prefer.

Other fti- mulants than purges have been employed in amenorrhoea, as the tinctura fabi- na compofua of the new London Pharmacopoeia; its dofe is thirty or forty drops, 'm any fuitable vehicle, as the tinctura myrrh fymptomatic of other affections, and is therefore not to be confidered here. 1009.] The idiopathic cafes of fuppreffion (1007.) ^ dom continue long without being attended with various fymptoms or diforders in different parts of the body; very commonly arifing from the blood which fhould have paff. ed by the uterus, being determined more copioufly into other parts, and very often with fuch force as to produce hemorrhagies in thefe. Hence hemorrhagies from the nofe, lungs, ftomach, and other parts, have appeared in confe- quence of fuppreffed menfes. Befides thefe, there are commonly hyfteric and dyfpeptic fymptoms produced by the fame caufe; and frequently cholic pains, with a bound belly. 1010.] In the idiopathic cafes of fuppreffion, (1007.) the indication of cure is to remove the conftriction affect. ing the extreme veffels ofthe uterus ; and for this purpofe the chief remedy is warm bathing applied to the region of the uterus. This, however, is not alwavs effeaual, and I do not know of any other remedy adapted to the indication. Befides this, we have perhaps no other means of removing the conftriBion in fault, but that of increafing the action and force ofthe veffels ofthe uterus, fo as thereby to over- come the refiftance or conftriction of the extremities. This therefore is to be attempted by the fame remedies in the ca.fe of fuppreffion, as thofe prefcribed in the cafes of re- tention (1003. 1005.) The tonics, however, and cold- bathing (1003.) feem to be lefs properly adapted to the t> F P H Y S I C. 19 cafes of fuppreffion, and have appeared to me of ambigu- ous effect.* 1011.] It commonly happens in the cafes of.fuppreffion, that though the menfes do not flow at their ufual periods, there are often at thofe periods fome marks of an effort having a tendency to produce the difcharge, It is there- fore at thofe times efpecially when the efforts ofthe fyf- tem are concurring, that we ought to employ the remedies for curing a fuppreffion; and it is commonly fruitlefs to employ them at other times, unlefs they be fucht as re- quire fome continuance in their ufe to produce their effects. 1012. J Nearly fimilar to the cafes of fuppreffion, are thofe cafes in which the menfes flow after long intervals, and in lcffer quantity than ufual; and when thefe cafes are attended with the diforders in the fyftem (1009.) they are to be cured by the fame remedies as the cafes of entire fup- preffion. 1013.] It may be proper in this place to take noticraf the defmenorrhea, or cafes of menftruation in which the menfes feem to flow with difficulty, and are accompanied with much pain in the back, loins, and lower belly. We impute this diforder partly'to fome weaker aaion ofthe veflels ofthe uterus, and partly, perhaps more efpecially, to a fpafm of its extreme veffels. We have commonly found the difeafe relieved by employing fome of the reme- dies of fuppreffion immediately before the approach ofthe period, and at the fame time employing opiates. CHAP. IX. £)f ^mptomatic ^emorrbagieau 1014.] J_ HAVE thought it very improper, in this work, to treat of thofe morbid affeaions that are almoft always fymptomatic of other more primary difeafes; and this for * The Emenagogues enumerated in the note on article 1006, are more effi- cacious in thefe cafes than the tonics and chalybeates mentioned in the note on article 1003, for this reafon, that the fuppreffion of the menfes depends more on the conftriction, than on a laxity of the extreme veffels. Some cafes indeed, occur, where a lax habit is the caufe of fuppreffion, but they are rare. The phyfician ought to be attentive in difcriminating fuch cafes, becaufe a liberal ufe of forcing emenagogues is always hurtful in them ; they can only be relieved by tonics, and Efpecially by chalybeates. t Vu. tonics or alterants. JO PRACTICE feveral reafons, particularly becaufe it introduces a gffcat deal of confufion in direBing praaice, and leads phyfici- ans to employ palliative meafures only. I fliall here, how- ever, deviate a little from my general plan, to make fome refleaions upon fymptomatic hemorrhagies. 1015.] The hemorrhagies of this kind that efpecially deferve our notice, are the Hematemefis, or Vomiting of Blood; and the Hematuria, or the Voiding of Blood from the urinary paffage. Upon thefe I am here to make fome remarks; becaufe, though they are very generally fymp- tomatic, it is poffible they may be fometimes primary and idiopathic affections; and becaufe they have been treated of as primary difeafes in almoft every fyftem of the prac- tice of phyfie. Sect. I. % Ofthe Hematemesis, or Vomiting of Blood. ioi 6.J I HAVE faid above in (944.) in what manner blood thrown out from the mouth may be known to pro* cced from the ftomach, and not from the lungs; but it may be proper here to fay more particularly, that this may be certainly known, when the blood is brought up manifeftly by vomiting without any coughing; when this vomiting has been preceded by fome fenfe of weight, anxiety, and pain, in the region of the ftomach; when the blood brought up is of a black and grumous ap- pearance, and when it is manifeftly mixed with other con- tents of the ftomach; we can feldom have any doubt of the fource from whence the blood proceeds, and therefore pf the exiftence of the difeafe we treat of. 1017.] We muft allow it to be poffible that a plethoric ftate of the body from general caufes may be accompani- ed with caufes of a peculiar determination and afflux of blood to the ftomach, fo as to occafion an hemorrhagy there, and thence a vomiting of blood; and in fuch a cafe this appearance might be confidered as a primary difeafe. But the hiftory of difeafes in the records of phyfie, afford little foundation for fuch a fuppofition; and on the con- trary, the whole ofthe inftances of a vomiting of blood which have been recorded, are pretty \panifeftly fymptom* atic of a more primary affection. • OF PHYSIC. 21 Of fuch fymptomatic vomitings of blood, the chief in- -, ftanccs are the following. 1018.] One ofthe moft frequent is that which appears in confequence of a fuppreffion of an evacuation of blood which had been for fome time before eftablifhed in another part of the body, particularly that of the menftrual flux in women. • 1019.] There are inftances of a vomiting of blood hap- pening from the retention ofthe menfes : but fuch inftances are very uncommon ; as retention of the menfes rare.ly happens in confequence of, or even with a plethoric ftate of the body; and as rarely does it produce that, or the hemorr- hagy in queftion. There are inftances of a vomiting of blood happening to pregnant women ; that might therefore alfo be impu- ted to the fuppreffion of the menfes, which happens to wo- men in that ftate. There have indeed been more inftan- ces of this than ofthe former cafe ; but the latter are ftill very rare: for although the blood which ufed to flow month- ly before impregnation, is, upon this taking place, retained, it is commonly fo entirely employed in dilating the uterine veffels, and in the growth of the foetus that it is feldom found to produce a plethoric ftate of the body, requiring a vicarious outlet. v. The vomiting of blood, therefore, that is vicarious of the menftrual flux, is that which commonly and almoft on- ly happens upon a fuppreffion of that flux, after it had been for fome time eftablifhed. 1020.] When fuch a fuppreffion happens, it maybe fup- pofed to operate by inducing a plethoric ftate of the whole body, and thereby occafioning hemorrhagy from othes parts of it; and hemorrhagies from many different parts of the body have been obferved by phyficians as occur- ring in confequence of the fuppreffion we fpeak of. It is however the great variety of fuch hemorrhagies, that leads me to think, that with the plethoric ftate ofthe whole body there muft be always fome peculiar circumftances in the part from which die blood flows, that determine its afflux to that particular, often Angularly odd, part; and diere- forc, that fuch hemorrhagies may from thefe circumftances occur without any confiderable plethora at the fame time prevaling in the whole fyftem. Vol. IJ. G 22 PRACT ICE 1021.} It is tobe obferved, that if we arc to expect an hemorrhagy in confequence of a fuppreffion of the menfe'l inducing a plethoric ftate of the fyftem, we fliould expea efpecially an hemoptyfis, or hemorrhagy from the lungs, as a plethora might be expected to fhow its effeas efpeci- ally there; and accordingly, upon occafion of fuppreffed menfes, that hemorrhagy occurs more frequently than any other : but even this, when it does happen, neither in its circumftances nor its confequences, leads us to fuppofe,| that at the fame time any confiderable or dangerous ple- thora prevails in the body. . 3 02 2.J Thefe confiderations in (1020. 1021.) will, I ap- prehend, apply to our prefent fubjea; and I would there^ fore alledgc, that a hematemefis may perhaps depend up- on particular circumftances of the ftomach determining an afflux of blood to that organ, and may therefore occur without any confiderable or dangerous plethora prevail- ing in the fyftem. What are the circumftances of the fto- mach, which upon the occafion mentioned, may determin© an afflux of bipod to it, I cannot certainly or clearly ex- plain ; but prefume that it depends upon the connection. and confent which we know to fubfift between the uterus and the whole of the alimentary canal, and efpecially that. principal part of it, the ftomach. 1023.] From thefe refteaions, we may, I think draw the following conclufions: I. That the hematemefis we fpeak of is hardly ever a dangerous difeafe. I;I. That it will hardly ever require the remedies fuit- ed to the cure of aaive hemorrhagy ; and at leaft that it w;ll require thefe only in thofe unufual cafes in which there appear ftrong marks of a general plethora, and in which the vomiting of blood appears to be confiderably aaive,, very profufe, and frequently recurring. III. That a vomiting of blood from fuppreffed menfes, ought feldom to prevent the ufe of thefe remedies of ame- norrhea, which might be improper in the cafe of an aaive idiopathic hemorrhagy. 1034,] Another cafe of fymptomatic hematemefis quite analagous to that already, mentioned, is.the hematemefis following, and feemingly depending upon,-the fuppreffion 0 rF P H Y S I C. gff of an hemorrhoidal flux, which had been eftablifhed and frequent for fome time before. ' This may perhaps be explained by a general plethoric, ftate induced by fuch a fuppreffion; and indeed fome de- gree of a plethoric ftate muft in filch a cafe be fuppofed to- take place; but that fuppofition alone will not explain the? whole of the cafe; for a general plethora would lead us ta txpeaan hemoptyfis (i02i.) rather than an hematemefis^ and there is therefore fomething ftill wanting, as in the former cafe} to explain the particular determination to the ftomach. - Whether fuch an explanation can be gdt'from the con- nexion between the different parts of the fahguiferous vef- fefs of the alimentary canal, Or from the connexion of the whole of thefe veffels with the vena portarum, I mall not venture to determine. But in the meah tiine I imagine, that the explanation required is rather to be detained from- #»at connexion of the ftomach with the hemorrhoidal af- feaion that I have taken notice of in (945J 1625. J H6w we may explain the hematemefis Occafi- oned by a fuppreflion of the hemorrhois, the confiderations in (load, 1021.) will apply here as in the analogous cafe1 of hematemefis from fuppreffed menfes; and will'therefore allow us alfo to conclude here, that the difeafe we now treat Ofwillferdoni be dangerous, and will feldom require the feme remedies that idiopathic and active hemorrhagy does.- 10267.] The cafes of hematemefis already mentioned* may be properly fuppofed to be hemorrhagies of the arte-' rial kind; but it is probable that the ftomach is alfo liable to hemorrhagies of the Venous kind (767.) In the records of phyfie therefcre many inftances of vo- miting blood, which were accompahied with a tumefied fpleen, which had eomprcfTed the vas breve, and thereby fVre-ventcdthe free return of venousblood from tfiLftomacrv How fuch an interruption of the venous blooTmay occa- fion-an hemorrhagy from either the extremities of the veins trvemferves, or from the extremities of their correfponderit arteries, we have explained above in (76&.J and the hifto-' nes of tumefied fitfeerrs compreffing the vafa brevia, afford ah excellent illuftration and confirmation of our doarine' 0V1 that fubject, and render it fufficiently jWbable that vomitings of Wood often arife from fuch a caufe, Vk PRACTICE 1027.] It is alfo poffible, that an obftruction of the li- ver refifting the free motion of the blood in the vena por- tarum, may fometimes interrupt free return of the venous blood from the veffels of the ftomach, and thereby occafi- on a vomiting of blood; but the inftances of this are nei- ther fo frequent nor fo clearly explained as thofe of the former cafe. 1028.J Befides thefe cafes depending on the ftate of the liver or fpleen, it is very probable that other hemorrhagies of the ftomach are frequently of the venous kind. The difeafe named by Sauvages Melaena, and by other writers commonly termed the Morbus Niger (771.] con- lifting in an evacuation either by vomiting or by ftool, and fometimes in both ways, of a black and grumous blood can hardly be otherwife occafioned, than by a venous hemorr- hagy from fome pfert of the internal furface of the alimen- tary canal. It is, indeed, poffible, that the bile may fometimes put on a black and vifcid appearance and give a real founda- tion for the appellation of an Atra Bilis : but it is certain, that inftances of this are very rare ; and it is highly pro- bable that what gave occafion to the notion of atra bilis among the ancients, was truly the appearance of blood pour- ed into the alimentary canal in the manner I have menti- oned ; and which appearance, we know, the blood always puts on when it has ftagnated there for any length of time. I fuppofe it is now generally thought, that Boerhaave's no- tion of fuch a matter exifting in the mafs of blood, is with- out any foundation; whilft, by diffeaions in modern times, it appears very clearly, that the morbus niger prefenting fuch an appearance of blood, always depends upon the e f- fufion and ftagnation I have mentioned. 1029.3 From this account ofthe melaena it will appear that vomiting of blood may arife in confequence of blood being poured out in the manner I have mentioned, either into the cavity of the ftomach itfelf, or into the fuperior portions of the inteftines, from whence matters often pafs into the ftomach. 1030.] Both in the cafe ofthe melaena, and in the ana- logous cafes from affeaions of the fpleen or liver, it will appear, that the vomitings of blood occurring muft he confidered as fymptomatic affections, not at all to be treat- OF PHYSIC. 25 cd as a primary aaive hemorrhagy, but by remedies, If any fuch be known, that may refolve the primary obflruv.- tions.* * This is doubtlefs the moft rational practice, namely, to rcf Ive the ob- ftrufVion which has occafioned the blood to be thrown or drive;, to the intef- tines. To difcover this primary obftruction is, however, extremely dillicult ; and, even when it is difcovered, it is frequently not eafily refolved ; in fuch cafes, therefore, we muft ufe the general remedies for removing the plethora, except laxatives, the operations of which, in general, derive the fluids fo the inteltines. Sweating is perhaps the beft general evacuation for determinir.g the fluids from the inteftines ; but its ufe ought to be preceded by bleeding : and icought not, in thefe cafes, to be excited by naufeating dofes of emetics, as thefe produce the fame effect as laxatives ; we muft therefore have re- courfe to the light aromatics, fage, mint, balm, white-whey, &c.

AU thefe ityptics and aftringeiftTarc xv\ 25 PRACTICE 1031.] I believe I have now mentioned almoft the whole ofthe caufes producing an hematemefis; and certainly the caufes mentioned, are thofe which moft commonly give occafion to that fymptom. Poffibly, however, there may be fome other caufes of it, fuch as that fingular one men- tioned by Sauvage of an aneurifm of the aorta burfting in- to the ftomach; and it is poffible, that fome difeafes of other contiguous parts, which have become clofely. ad- hering to the ftomach, may fometimes, by a rupture into the cavity of the ftomach, pour blood into it, which is af- terwards rejected by vomiting. It is poffible alfo, that abfeeffes and ulcerations of the ftomach itfelf, may fome- times pour blood into its cavity to be thrown up by vo- miting. I did not think it neceffary, among the fymptomatic vo- mitings of blood, to enumerate thofe from external vio- lence, nor, what is analogous to it, that which arifes from violent ftraining to vomit; which laft, however, is much more rare than might be expected. In either of thefe cafes the nature of the difeafe cannot be doubtful, and the ma- nagement of it will be readily underftood from what has been delivered above with refpect to moderating and ref- training hemorrhagy in general. Sect. II. Of the Hematuria, or the Voiding of Blood from the Uri- nary Passage. 1032.J IT is alleged, that an hematuria has occurred without any other fymptom of an affection of the kidneys or urinary paffages being prefent at the fame time; and as this happened to plethoric perfons, and recurred at fixed periods, fuch a cafe has been fuppofed to be an inltance of idiopathic hematuria, and of the nature of thofe active he- morrhagies I have treated of before. 1033-J I cannot pofitively deny the exiftence of fuch a cafe; but muft obferve, that there are very few inftances of to produce coftivenefs, which muft be removed by emollient glyfters as lax- ative medicines are, for the reafons above mentioned, generally hurtful in thefe cafes. The young practitioner muft not truft. to tftefe medicines for completely curing a hemorrhage frorrtfhe inteftines; they are only palliatives, and are of no other ufe than to check the violence of the difeharge until the? true cauf^of the difeafe be drfcovered; and the difeoyery ef this caufe mull be Jeft to the fagaeity of the phyfician. OF PHYSIC. 2* fuch upon the records of phytic ; that none have ever ocl curred to my obfervation, or to that of my friends; and that the obfervations adduced may be fallacious, as I have frequently obferved an hematuria without fymptoms of other affection ofthe kidney or urinary paflages being, for the time, prefent; whilit, however, fits of a nephralgia cal- culofa having, before, or foon after, happened, rendered it to me fufticiently probable, that the hematuria was owin* to a wound made by a ftone prefent in fome part of the urinary paflages. 1034-J The exiftence of an idiopathic hematuria is fur- ther improbable, as a general plethora is more likely to produce an hemoptyfis (1021.) and as we do not well know of any circumftances which might determine more particularly to the kidneys. An idiopathic hematuria, there- fore, mult certainly be a rare occurrence; and inftances of fymptomatic affections of the fame kind are very frequent. *°35-] O*16 of the mofl frequent is, that hematuria which attends the nephralgia calculofa, and feems mani- feftly to be owing to a ftone wounding the internal furface of the pelvis of the kidney or of the ureter. In fuch cafes, the blood difcharged with the urine is fometimes, of a pret- ty florid colour, but for the moft part isof a dark hue: the whole of it is fometimes diffufed or diffolved, and therefore entirely fufpended in the urine; but if it is in any large quantity, a portion of it is depofited to the bottom of the veffel containing the voided blood and urine. On differ- ent occafions, the blood voided puts on different appear- ances. If the blood poured out in the kidney has happen- ed to ftagnate for fome time in the ureters or bladder, it is fometimes coagulated, and the coagulated part is after- wards broken down-into a grumous mafs of a black or dark colour, and therefore gives the fame colour to the urine voided; or if the quantity of broken down blood is finall, it gives only a browniIn urine refembling coffee. It fometimes alfo happens, that the blood ftagnating and coagulating in the ureters, takes the form "of thefe veffels, and is therefore voided under the appearance of a worm: and if the coagulated blood happens to have, as it may fometimes have, the gluten feparated from the globules, thefe worm-like appearances have their external furface whitifh, and the whole feemingly forming a tube contain- 28 PRACTICE ing a red liquor. I have fometimes obferved the blood which had feemingly been coagulated in the ureter, come away in an almoft dry ftate, refembling the half burnt wick of a candle.* 1036.] Thefe are the feveral appearances of the blood voided in the hematuria calculofa, when it proceeds efpe- cially from the kidneys or ureter; and many of the fame appearances are obferved when the blood proceeds only from the bladder when a ftone is lodged there; but the attending fymptoms will commonly point out the different feat of the difeafe. In one cafe, when a quantity of blood from the kidney or ureter is coagulated in the bladder, and is therefore dif- ficultly thrown out from this, the pain and uneafinefs on fuch an occafion may appear chiefly to be in the bladder, though it contains no ftone; but the antecedent fymptoms will commonly difcover the nature of the difeafe. 1037.] *n an)' °f tne ca^es °f me hematuria calculofa, it will hardly be neceffary to employ the remedies fuited to an active hemorrhagy. It will be proper only to em. ploy the regimen fit for moderating hemorrhagy in general, and particularly here to avoid every thing or circumftance that might irritate the kidneys or ureters. Of fuch cafes of irritation there is none more frequent or more confider* able than the prefence of hardened fa?ces in the colon; and thefe therefore are to be frequently removed by the frequent ufe of gentle laxatives.t 1038. J The hematuria calculofa J may be properly • In general, the blood is coagulated and grumous ; hence the urine depoflts a dark brown fubftance fomewhat refembling coffee-grounds. As the grum- ous blood is fpecifically heavier than the urine, it falls to the bottom of the bladder, and is confequently voided in greater quantity in the beginning than towards the end of making water, the urine that comes off firft being very deep coloured and muddy, but becoming, while it flows, gradually more tranf- parent and pure, until at laft it is perfectly of a natural appearance. The pa- tient generally mentions this circumftance in defcribing his complaints, with this addition, that he has in t\.e beginning fome difficulty of making water, but that this difficulty decreafes in proportion as the urine becomes more tranfparent. f Glyfters are preferable to purgatives in thefe cafes, becaufe they are lefi ftimulating; and the emollient glyfters are preferable to all others, for their only intention is to foften the hardened faeces. The only purgatives to be tifedr are thofe ofthe mildeft kind, as manna, oil, caffia, &c. The intention of purgatives, in thefe cafes, is only to remove the hardened faeces ; and this intention can often be fufficiently anfwered by a proper choice of food, as broths, efpecially thofe made with barley and young animal flefti; barley gruel, with prunes boiled in it; fiewed endive, lettuce, and otheroleraceousdimes. J The hematuria calculofa being fymptomatic, can only be cured by remov- ing the caufe; it may, however, be greatly relieved by demulcents, as lint- OF PHYSIC ■ 89 confidered as a cafe ofthe hematuria violenta: and there- fore I fubjoin to that the other inftances of hematuria from external violence; fuch as that from external contufion on the region of the kidney,* and that from the violent or long continued exercife of the mufcles incumbent on the kidneys. An inltance of the latter caufe occurs efpecially in riding.t 1039.] It may alfo be confidered as a cafe of the hema- turia violenta, when the difeafe occurs in confequence of the taking in of certain acrid fubftances, which pafs again efpecially by the urinary paflages; and by inflaming and fwelling the neck of the bladder, bring on a rupture ofthe over diftended blood-veffels, and give occafion to a bloody urine. The moft noted inftance of this is in the effect of cantharides in a certain quantity, any way introduced into the body. And poffibly fome other acrids may have the fame effect. J 1040. J Befide thefe moft frequent inftances of hematu- ria, which cannot be confidered as idiopathic hemorrhagies, there are fome other inftances of hematuria mentioned by feed tea, decoction of marfli-mallows, mucilage of gum Arabic, thick barley- water, he. * The hematuria proceeding from a contufien of the region of the kidneys requires general and topical bleeding, with purges, and an attention to the antiphlogiftic regimen. Some practitioners recommend the warm balfams in ■thtjle cafes; but, on account of their heating quality, their ufe is fomewhat doubtful. Nitre is not always admiffible, on account of its irritating the kid- neys ; but it is a powerful antiphlogiftic ; and, if it is ufed in thefe cafes, rt muft be well diluted : the mucilaginous drinks are abfolutely neceffary, and ought to be ufed plentifully. f The only method of treating this kind of hematuria is by reft. A perfon ful>ject to it ought never to ride | This fpecies of hematuria is cured by evacuating the acrid fubftance, and by the ufe of the mucilaginous drinks before mentioned. The acrid fubftance may be evacuated by antiphlogiftic purges, or by the milder diuretics, as nitre, decoctions of parlley roots, cream of tartar, whey, &c. The action of can- tharides on the urinary paflages is not well explained. We can fcarcely be- lieve that any part of the cantharides is abforbed from the bliftering plaifter; yet its effects are the fame with thofe produced by taking the cantharides in- ternally. The llrjingury, and .its concomitant fymptoms, may be relieved by large and plentiful dilution, and a free ufe ofthe mucilaginous drinks.

Thefe may be confidered as analogous to the hematemefis produced by the like caufes ; and the feveral reflections made above on that fubject, will I think, apply here, and particularly the conclufions formed in (1023.) Inftances, however, of either of thefe cafes, and efpecially ofthe firft, have been extremely rare. 1041. J Of fuch fymptomatic hematuria there is howe- ver one inftance deferving notice; and that is, when a fup- preffion ofthe hemorrhoidal flux, either by a communica- tion of veffels, or merely by the vicinity of parts, occa- fions a determination of the blood into the veffels of the neck of the bladder, which in confequence of a rixis or anaftomofis, pour out blood to be voided either with or without urine. This caufe is what has been named the Hemorrhoides Veficae; and with fome propriety, when it ris manifeftly an evacuation vicarious of what had before been ufually made from the rectum. With refpect to the management of the hemorrhoides veficae, I would apply the whole ofthe doctrines that I have delivered above, with refpect to the cure of the proper hemorrhoidal affedion.* 1042.] There remains ftill to be mentioned one other , inftance of fymptomatic hematuria, which is that which j happens in the cafe of confluent and putrid fmall-pox, as well as in feveral other inftances of putrid difeafes. The 1 blood, in fuch cafes, may be prefumed to come from the kidneys; and I apprehend that it comes from thence in confequence of that fluidity which is always produced in the blood approaching to a putrid ftate. Such hematuria, therefore, is not to be confidered as a fymptom of any af- fection ofthe kidneys, but merely as a mark of the putref- cent ftate of the blood. 1043.] *n certam difeafes the urine is difcharged of fuch < a deep red colour, as to give a fufpicion of its being ting- ed by blood prefent in it; and this has given occafion to Sauvages, amongft the other fpecies of hematuria, to mark the hematuria fpuria, and the hematuria lateritia ; both of which, however, he fuppofes to be without any blood pre- fent in the urine. In many cafes it is of importance, in * Articles 846. et fequent. OF FH Y SIC. afccrtaining the nature ofthe difeafe, to-determine whether the red colour of urine be from blood prefent in it, or from a certain ftate of the falts and oils which are always in greater or leffer proportion conftituent parts of the urine; and the queftion may be commonly determined by the following confidcrations. It has been obferved above, that when any confiderable quantity of blood is voided with the urine, there is always a portion of it depofited at the bottom of the veffel con- taining the voided blood and urine: and in fuch a cafe there will be no doubt in attributing the colour of the urine float- ing above to fome part of the blood diffufed in it. The q ueftion, therefore, with refpect to the prefence of blood in the urine can only occur when no fuch depofition as I have mentioned appears; and when the blood that may be fuppofed to be prefent is diffolved or diffufed, and there- fore entirely fufpended in the urine. In this cafe the pre- fence ofthe blood may be commonly known, ift, By the colour, which blood gives, different from any urine w ithout blood that I have ever feen; and I think a little experience will enable molt perfons to make this diftinction.. 2dly, By this, that the prefence of blood always diminifhes the trans- parency ofthe urine with which it is mixed; and it is very feldom that urine, though very high coloured, lofes its tranfparency; at leaft this hardly ever appears, if the urine is examined when recently voided. 3dly, When urine has blood mixed with it, it tinges a piece of linen dipped into it with a red colour, which the higheft coloured urine without blood, never does.. 4thly, High coloured urine without blood, upon cooling, and remaining at reft in a veflel, almoft always depofites a lateritious fediment; and if upon any occafion bloody urine fhould depofit a fedi- ment that may be of a portion ofthe blood formerly dif- fufed in it, the difference, however, may be difcerned by this, that the fediment depofited by urine without blood, upon the ..rincs being again heated, will be entirely redif- folved, which will not happen to any fediment from blood.. Laftly, we know no ftate of urine without blood, which fhews any portion of it, coagulated by a heat equal to that of boiling water; but blood diffufed in urine is ftill coagu. lable by fuch a heat; and by this teft, therefore, the pro* fence of blood in urine may be commonly afcertained^ t 'S2 ] BOOK V. Of Profluvia, or Fluxes, with Pyrexia. 1044.] JL ORMER nofologifts have eftablifhed a clafs of difeafes under the title of Fluxes, or Profluvia; but as in this clafs they have brought together a great number of difeafes, which have nothing in common, excepting the fingle circumftance of an increafed difcharge of fluids, and which alfo are, in other refpeefs, very different from one another; I have avoided fo improper an arrangement, and have diftributed moft ofthe difeafes comprehended in fuch a clafs by the nofologifts, into places more natural and proper for them.* I have, indeed, ftill employed here the general title; but I confine it to fuch fluxes only as are conftantly attended with pyrexia, and which therefore ne- ceffarily belong to the clafs of difeafes of which I am now treating. Of the fluxes which may be confidered as being very conftantly febrile difeafes, there are only two, the catarrh and dysentery; and of thefe therefore I now proceed to treat. CHAP. I. £)f t{je Catarrh 1045.] X HE catarrh is an increafed excretion of mu- cus from the mucous membrane of the nofe, fauces, and bronchia?, attended with pyrexia. Practical writers and nofologifts have diftinguifhed the difeafe by different appellations, according as it happens to affect thofe different parts ofthe mucous membrane, the one part more or lefs than the other: But I am of opinion, that the difeafe, although affecting different parts, is al- ways of the fame nature, and proceeds from the fame caufe. Very commonly, indeed, thofe different parts are affected at the fame time; and therefore there can be little room for the diftinction mentioned. * Sausages enumerates no lefs than thirty-fix genera of fluxes, each of which are fubdivided into numerous fpecies. Vogel has forty-five ger.era, under the title of Profliivia, moft of which are extremely different frcm each other in their effential qualities. OF PHYSIC. S3 The difeafe has been frequently treated of under the ti- tle of Tuffis, or Cough; and a cough, indeed, always at- tends the chief form of catarrh, that is, the increafed ex- cretion from the bronchiae: but a cough is fo often a fymp- tom of many other affections, which are very different from one another, that it is improperly employed as a generic title. 1046.] The remote caufe of catarrh is moft commonly cold applied to the body. This application of cold pro- ducing catarrh, can in many cafes be diflinctly obferved; and I would believe it always to be fo, were men acquaint- ed with, and attended to, the circumftances which deter- mine cold to act upon the body. See (94—96.) From the fame paragraphs we may learn what in fome perfons gives a prediipolition to catarrh. i<*47-] The difeafe, of which I am now to treat, ge- nerally begins with fome difficulty of breathing through the nofe, and with a fenfe of fome fullnefs flopping up that paffage. This is alfo often attended with fome dull pain and a fenfe of weight in the forehead, as well as fome itiff- nefis in the motion of the eyes. Thefe feelings, fometimes at their very firft beginning, and always foon after, are at- tended with the diftillation from the nofe; and fometimes from the eyes, of a thin fluid, which is often found to be fomewhat acrid, both by its tafte, and by its fretting the parts over which it pafles. 1048. J Thefe fymptoms conftitute the coryza and^nz- vedo of medical authors, and are commonly attended with a fenfe of laffitude over the whole body. Sometimes cold fhiverings are felt, at leaft the body is more fenfible than ufual to the coldnefs ofthe air; and with all this the pulfe becomes, efpecially in the evenings, more frequent than ordinary. 1049.J Thefe fymptoms feldom continue long before they are accompanied with fome hoarfenefs, and a fenfe of roughnefs and forenefs in the trachea, and with fome dif- ficulty of breathing, attributed to a fenfe of ftraitnefs of thecheft, and attended with a cough, which feems to arife from fome irritation felt at the glottis. The cough is ge- nerally at firft dry, occafioning pains about the cheft, and more efpecially in the breaft. Sometimes, together with thefe fymptoms, pains refembling thofe of the rheumatifm 34 PRACTICE are felt in fevcral parts of the body, particularly about the neck and head. While thefe Iymptoms take place, the appetite is impaired, fome thirft arifes, and a general laf- fitudc is felt over all the body. 1050. j Thefe fymptoms (1047.—1°49-] mark the vio- lence and height ofthe difeafe; which, however, docs not commonly continue long. By degrees the cough becomes attended with a copious excretion of mucus; which is at firft thin, but gradually becoming thicker, is brought up with lefs frequent and lefs laborious coughing. The hoarle- nefs and forencis of the trachea likewife going off, the fe- brile fymptoms abating, the cough becoming lefs frequent, and with lefs expectoration, the difeafe foon after ceafes altogether. • 1051.] Such is generally the courfe of this difeafe, which is commonly neither tedious nor dangerous; but, upon fome occafions, it is in both refpects otherwife. A perfon affected with catarrh feems to be more than ufually liable to be affected by cold air; and in that condition, if expofed to cold, the difeafe, which feemed to be yielding, is often brought back with greater violence than before; and is rendered not only more tedious than otherwife in would have been, but alfo more dangerous by the fuper- vening of other difeafes. 1052.J Some degree of the cynanche tonfillaris often accompanies the catarrh; and, when the latter is aggravat- ed by a frefh application of cold, the cynanche alfo be- comes more violent and dangerous, in confequence of the cough which is prefent at the fame time. 1053. J When a catarrh has been occafioned by a violent caufe; when it has been aggravated by improper manage- ment; and efpecially when it has been rendered more vio- lent by frefh and repeated applications of cold, it often paifes into a pneumonic inflammation attended with the utmolt danger. 1054.] Unlefs, however, fuch accidents as thofe of (1051.—1053.) happen, a catarrh, in found perfons not far advanced in life, is, I think, always a flight difeafe, and attended with little danger. But, in perfons of a phthi- fical difpofition, a catarrh may readily produce an hemop- tyfis, or perhaps form tubercles in the lungs; and more certainly, in perfons who have tubercles already formed 111 OF PHYSIC 35 the lungs, an accidental catarrh may occafion the inflam- mation of thefe tubercles, and in confequence produce a phthifis pulmonalis. 1055. J *n ^derly perfons, a catarrh fometimes proves a dangerous difeafe. Many perfons, as they advance in life, and efpecially after they have arrived at old age, have the natural mucus of the lungs poured out in greater quan- tity, and confequently requiring a frequent expectoration. If tlierefore a catarrh happen to fuch perfons, and increafe the influx of fluids to the lungs, with fome degree of in- flammation, it may produce the peripneumonia notha, which in fuch cafes is very often fatal. See (376. 382.) 1056.] The proximate caufe of catarrh feems to be an increafed afflux of fluids to the mucus membrane of the nofe, fauces, and bronchiae, along with fome degree of in- flammation affecting thefe parts. The latter circumftance is confirmed by this, that in the cafe of catarrh, the blood drawn from a vein commonly exhibits the fame inflamma- matory cruft which appears in the cafe of phlegmafiae. 1057.J The application of cold which occafions a ca- tarrh, probably operates by diminifhing the perfpiration ufually made by the fkin, and which is therefore determin- ed to Ute mucus membrane of the parts above mentioned. Asa part of the weight which the body daily lofes by infen- fible evacuation, is owing to an exhalation from the lungs, there is probably a connection between this exhalation and the cutaneous perfpiration, fo that the one may be increafed in proportion as the other is diminifhed: And therefore we may undcrftand how the diminution of cutaneous per^ fpiration, in confequence of the application of cold, may increafe the afflux of fluids to the lungs, and thereby pro- duce a catarrh. 1058.] There are fome obfervations made by Dr. James Keil which may feem to render this matter doubt- ful; but there is a fallacy in his obfervations. The evi- dent effects of cold in producing coryza, leave the matter in general without doubt; and there are feveral other cir- cumftances which fhow a connection between the lungs and the furface ofthe body. 1059.] Whether, from the fuppreffion of perfpiration, a catarrh be produced merely by an increafed afflux of fluids, or whether the matter of perfpiration be at the fame 86 PRACTICE time determined to the mucous glands, and there excite a particular irritation, may be uncertain; but the latter fup- pofition is fufficiently probable. ic6o.] Although, in the cafe of a common catarrh, which is in many inftances fporadic, it may be doubtful whether any morbific matter be applied to the mucous glands; it is, however, certain, that the fymptoms of a catarrh do frequently depend upon fuch a matter being ap- plied to thefe glands; as appears from the cafe ofthe mea- fies, chin-cough, and efpecially from the frequent occur- rence of contagious and epidemical catarrh. 1061. J The mention of this laft leads me to obferve, that there are two fpecies of catarrh, as I have marked in my Synopfis of Nofology. One of thefe, as I fuppofe, is produced bv cold alone, as has been explained above; and the other feems manifeftly to be produced by a fpeci- fic contagion. Of fuch contagious catarrhs,* I have pointed out in the Synopfis many inftances occurring from the 14th century down to the prefent day. In all thefe inftances the pheno- mena have been much the fame ; and the difeafe has always been particularly remarkable in this, that it had been the moft widely and generally fpreading epedemic known. It has feldom appeared in any one country of Europe, without appearing fucceffively in every other part of it; and in fome inftances, it has been even transferred to Ame- rica, and has been fpread over that continent, fo far as we have had opportunities of being informed. 1062.J The catarrh from contagion appears with nearly the fame fymptoms as thofe mentioned (1047—1049-) *' feems often to come on in confequence of the application of cold. It comes on with more cold fhivering than the catarrh arifing from cold alone, and fooner fhows febrile fymptoms, and thefe likewife in a more confiderable degree. Accordingly, it more fpeedilyruns its courfe, which is com- monly finifhed in a few days. It fometimes terminates by a fpontaneous fweat; and this in fome perfons, produces a miliary eruption. It is, however, the febrile ftate of this difeafe efpecially, that is finiflied in a few days ; for the cough, and other catarrhal fymptoms, do frequently con- • Thefe epidemical catarrh* hav« twen lately termed Influenzas. ■OF PHYSIC. -37 tlnue longer; and often, when they appear to be going off, they are renewed by any frefh application of cold. 1063.] Confidering the number of perfons who are af- fected with catarrh, of either the one fpecies or the other, andefcape from it quickly without any hurt, it may be al- lowed to be a difeafe very free from danger : but it is not always to be confidered as fuch ; for in fome perfons it is accompanied with pneumonic inflammation. In the phthi- fically difpofed, itoften accelerates the camming on of phthi- fis ; and in elderly perfons, it frequently proves fatal in the manner explained above, (1053. and 1055.) 1064.] The cure of catarrh is nearly the fame, whether it proceed from cold or contagion ; with this difference, that in the latter cafe, remedies are commonly more necef- fary than in the former. In the cafes of a moderate difeafe, it is commonly fuf- ficient to avoid cold, and to abftain from animal food for fome days ;* or perhaps to lie a-bed, and, by taking fre- quently of fome mild and dilueru drink a little warmed, to promote a very gentle fweat; and after thefe to take car6 to return very gradually only, to the ufe ofthe free air. 1065.] When the difeafe is more violent, not only the antiphlogiftic regimen muft be exactly obferved, but va- rious remedies alfo become neceffary. To take off the phlogiftic diathefis which always attends this difeafe, bloodletting, in a larger or fmaller quantity, and repeated according as the fymptoms fliall require, is the proper remedy. For reftoring the determination of the fluids to the fur- face ofthe body,t and at the fame time for expeding the * Perhaps an abftinence from all food would accelerate the cure > The mu- cilaginous drinks ought to be taken in conilderable quantities, and they are fomewhat nutritive. t The means of producing a gentle and continued perfpiration have been mentioned in a former note. In catarrh, however, the ufe of the warmer fu- ctorifics feems moft effectual. The elixir paregoricum, diluted with whey, ef- pecially whey made with the dulcified fpirit of nitre, is of finguiar ufe ; but it ought not to be given if there is a confiderable degree of phlogiftic diathe- fis. In this cafe, a fpoonful of the following folution may be given every two or three hours, till a fweat break out: ft. Tart. emet. gr. ii. Aq. font. Bv>« ?vr. Althsex 5ii. M.

PRACTICE fecretion of mucus in the lungs, which may take off the inflammation of its membrane, vomiting is the moft effec- tual means. For the latter purpofe, it has been fuppofed, that fquills, gum ammoniac,* the volatile alkali, and fome other me- dicines, might be ufeful: But their efficacy has never ap- peared to me to be confiderable ; and, if fquills have ever been very ufeful, it feems to have been rather by their eme- tic, than by their expectorant powers. When the inflammatory affections of the lungs feem to be confiderable, it is proper, befides blood-letting, to ap- ply blifters on fome part ofthe thorax. As a cough is often the moft troublefome circumftance of this difeafe, fo demulcents may be employed to allevi- ate it. See (373.) But after the inflammatory fymptoms have much abat- ed, if the cough fhould ftill continue, opiates afford the moft effectual means of relieving it; and in the circumftan- ces juft now mentioned, they may be very fafety employ- ed. See (375.) After the inflammatory and febrile ftates of this difeafe are almoft entirely gone, the moft effectual means of dif- cufling all remains of the catarrhal affection, is by fome •exercife of geftation diligently employed. CHAP. II. 1066.] X HE dyfentery is a difeafe in which the patient has frequent ftools accompanied with much griping, and followed by a tenefmus. The ftools, though frequent, are generally in fmall quantity; and the matter voided is cheif- demulcent, as Extra& of liquorice, &c. or to take a tea-fpoonful of equal parti of oil and honey, in order to prevent the (harp matter from irritating the fau- ces. The Ele&. Peflorale of the Edinburgh Pharmacopoeia not only relieves the tickling, but tends to produce a falutary diaphorefis; its dofe is the fize of a nutmeg three or four times a-day. * The ammoniac and fquills may be joined together in the following form: R.

At the fame time • the natural faeces feldom appear, and, when they do, it is- generally in a compact; and hardened form. 1067.] This difeafe occurs efpecially in fummer and au- tumn, at the fame time with autumnal intermittent and re- mittent fevers; and with thefe it is fometimes combined or eomplicatedi* 1068.J The difeafe comes on fometimes with cold fni- verings, and other fymptoms of pyrexia; but more com- monly the fymptoms of the topical affection appear firft. The belly is coftive, with an unufual flatulence in the bowels. Sometimes, though more rarely, fome degree of diarrhoea is the firft appearance. In moft cafes the difeafe begins w7ith griping, arid a frequent inclination to go to- ftool. In indulging this, little is voided ; but fome tenef- mus attends it. By degrees, the ftools become more fre- quent, the griping more fevere, and the tenefmus more confiderable. Along with thefe fymptoms there is a lofs of appetite; and frequently ficknefs, naufea, and vomiting, alfo affecting the patient. At the fame time there is always more or lefs of pyrexia prefent, which is fometimes ofthe remittent kind, and obferves a tertian period.—Some- times the fever is manifeftly inflammatory, and very often of a putrid kind.. Thefe febrile ftates continue to accom- pany the difeafe during its whole courfe, efpecially when it terminates foon in a fatal manner. In other cafes, the fe- brile ftate almoft entirely difappears, while the proper dyfenteric fymptoms remain for a long time after. 1069. J In the courfe of the difeafe, whether of fhorter or longer duration, the matter voided by ftool is very vari- ous. Sometimes it is merely a mucous matter, without any blood exhibiting that difeafe which Dr. Roderer has named the morbus mucosus, and others the dy sent aria alba. For the moft part, however, the mucus difcharged is more or lefs mixed with blood. This fometimes appears only in ftreaks amongft the mucus; but at other times is more copious, tinging the whole of the matter difcharged; and upon fome occafions a pure and unmixed blood is voided in confiderable quantity. In other refpects, the matter voided is varioufiy changed in colour and confiftence, and • It appears more efpecially in armies encamped in low fwampy ground^ and, without proper management, is highly deftructive« 4* PRACTICE is commonly of a ftrong and unufually fetid odour. It 19 probable, that fometimes a genuine pus is voided; and frequently a putrid fanies, proceeding from gangrenous parts. There are very often mixed with the liquid matter fome films of membranous appearance, and frequently fome fmall maffes of a feemingly febacious matter. 1070.] While the ftools confifting of thefe various mat-, ters are in many inftances, exceedingly frequent, it is fel- dom that natural faeces appear in them; and when they do appear, it is, as I have mentioned, in the form oi fcybala, that is, in fomewhat hardened, feparate balls. When thefe are voided, whether by the efforts of nature, or as folicited by art, they procure a remiffion of all the fymp- toms, and more efpecially of the frequent ftools, griping-, and tenefmus. 1071. J Accompanied with thefe circumftances, the dif- eafe proceeds for a longer or a fhorter time. When the pyrexia attending it is of a violent inflammatory kind, and more efpecially when it is of a very putrid nature, thedif, eafe often terminates fatally in a very few days, with all the marks of a fupervening gangrene. When the febrile ftate is more moderate, or difappears altogether, the dif- eafe is often protracted for weeks, and even for months; but even then, after a various duration, it often terminates fatally, and generally in confequence of a return and con- fiderable aggravation ofthe inflammatory and putrid ftates. In fome cafes the difeafe ceafes fpontaneoufly; the frequen- cy of ftools, the griping, and tenefmus, gradually diminifh- es, while natural ftools return. In other cafes, the difeafe with moderate fymptoms, continue long, and ends in a di- arrhcea, fometimes accompanied with lienteric fymptoms. 1072.] The remote caufe of this difeafe have been vari- oufly judged of. It generally arifes in fummer or autumn after confiderable heats have prevailed for fome time, and efpecially after very warm, and at the fame time very dry ftates of the weather; and the difeafe is more frequent in warm, than in cooler climates.—It happens, therefore, in the fame circumftances and feafons which confiderablv af- fect the ftate of the bile in the human body ; but as the cholera is often without any dyfenteric fymptoms, and co- pious difcharges of bile have been found to relieve the 0 F P H Y S I C. 41 fymptoms of dyfentery, it is difficult to determine what connection the difeafe has with the ftate of the bile. 1073.] It has been obferved, that the effluvia from very putrid animal fubftances, readily affect the alimentary ca, nal; and upon fome occafions they certainly produce a diarrhoea; but, whether they ever produce a genuine dy- fentery, I have not been able to learn with certainty. 1074.] The dyfentery does often manifeftly arife from the application of cold, but the difeafe is always contagi- ous : and, by the propagation of fuch contagion, indepen* dent of cold, or other exciting caufes, it becomes epidemic in camps and other places. It is, therefore, to be doubt- ed, if the application of cold does ever produce the difeafe* unlefs where the fpecific contagion has been previoufly re- ceived into the body: And upon the whole, it is probable* that a fpecific contagion is to be confidered as always the remote caufe of this difeafe. 1075.] Whether this contagion, like many others, be of a permanent nature, and only fhows its effects in certain circumftances which render it active, or if it be occafion- ally produced, I cannot determine. Neither, if the latter fuppofition be received, can I fay by what means it may be generated. As little do we know any thing of its na- ture, confidered in itfelf; or at moft this only, that, in common with many other contagions, it appears to be com- monly of a putrid nature, and capable of inducing a pu- trefcent tendency in the human body. This, however, does not at all explain its peculiar power in inducing thofe fymptoms which properly and effentiaUy conftitute the difeafe of dyfentery. (1066.) 1076.] Of thefe fymptoms the proximate caufe is ftill obfeure. The common opinion has been, that the difeafe depends upon an acrid matter received into, or generated in the inteftines themfelves, exciting their periftaltic mo- tion, and thereby producing the frequent ftools which oc* cur in this difeafe. But this fuppofition cannot be admit- ted ; for in all the inftances known of acrid fubftances ap- plied to the inteftines and producing frequent ftools, they at the fame time produce copious ftools, as might be ex- pected from acrid fubftances applied to any length of the inteftines. This, however, is not the cafe in dyfentery ; in which the ftools, however frequent, are generally in very 42 PRACTICE fmall quantity, and fuch as may be fuppofed to proceed from the lower parts of the rectum only. With refpect to the fuperior portions ofthe inteftines, and particularly thofe ofthe colon, it is probable they arc under a preter- natural and confiderable degree of conftriction: For, as I have obferved above, the natural fa?ces are feldom void- ed; and when they are, it is in a form which gives reafon to fuppofe, they have been long retained in the cells of the colon, and confequently that the colon had been affected with a preternatural conftriction. This is confirmed by almoft all the defections which have been made of the bo- dies of dyfenteric patients, in which, when gangrene had not entirely deftroyed the texture and form of the parts, confiderable portions of the great guts have been found af- fected with a very confiderable conftriction. 1077.] I apprehend, therefore, that the proximate caufe of dyfentery, or at leaft the chief part of the proximate caufe, confifts in a preternatural conftriction of the colon, occafioning at the fame time thofe fpafmodic efforts which are felt in fevere gripings, and which efforts, propagated downwards to the rectum, occafion there the. frequent mu- cous ftools and tenefmus. But, whether this explanation (hall be admitted or not, it will ftill remain certain, that hardened faeces retained in the colon are the caufe of the griping, frequent ftools, and tenefmus; for the evacuation of thefe faeces, whether by nature or by art, gives relief from the fymptoms mentioned; and it will be more fully and ufefully confirmed by this, that the moft immediate and fuccefsful cure of dyfentery is obtained by an early and conftant attention to the preventing the conftriction, and the frequent ftagnation of faeces in the colon. 1078.] In this manner I have endeavoured to afcertain the proximate caufe of dyfentery, and therefore to point out alfo the principal part ofthe cure, which, from want of the proper view of the nature of the difeafe, feems to have been in feveral refpects fluctuating and undetermined among practitioners. 1079-J The moft eminent of our late practitioners, and of the greateft experience in this difeafe, feem to be of opi- nion, that the difeafe is to be cured moft effectually by purging affiduoufly employed. The means mav be vari- ous; but the moft gentle laxatives are ufually fufficient; OF PHYSIC. 42 and as they muft be frequently repeated, the moft gentle are the molt fafe; the more efpecially as an inflammatory ftate fo frequently'accompanies the difeafe. Whatever laxatives produce an evacuation of natural faeces, and a confequent remiffion of the fymptoms, will be fufficient to effectuate the cure. But if gentle laxatives fhall not produce the evacuation now mentioned, fome more pow- erful medicines muft be employed;* and I have found no- thing more proper or convenient than tartar emetic, given in fmall dofes, and at fuch intervals as may determine their operation to be chiefly by ftool. Rhubarb, fo frequently employed, is in feveral refpects amongft the moft improper purgatives. 1080. J Vomiting has been held a principal remedy in this difeafe; and may be ufefully employed in the begin- ning of it, with a view to both the ftate ofthe ftomach and of the fever; but it is not neceffary to repeat it often; and unlefs the emetics employed operate alfo by ftool, they are of little fervice. Ipecacuanha feems to poffefs no fpecific power ; and it proves only ufeful when fo ma- naged as to operate chiefly by ftool. 1081.] For relieving the conftriction of the colon, and evacuating the retained fseces,t glyfters may fometimes be ufeful: but they are feldom fo effectual as laxatives given by the mouth; and acrid glyfters, if they be not effectual in evacuating the colon, may prove hurtful by ftimulating the rectum too much.

In the fame cafe, the pains may be re- lieved, and, as I think, the conftritlion ofthe colon may be taken oft, by blifters applied to the lower belly.t 1084.] At the beginning of this difeafe, when the fever is any way confiderable, biood-letting, in patients of tolera- ble vigour, may be proper and neceffary ; and, when the pulfe is full and hard, with other fymytoms of an inflam- matory difpofition, blood-letting ought to be repeated. But, as the fever attending dyfentery is often of a putrid kind, or does, in the courfe of the difeafe, become foon of that nature, blood-letting muft be employed with great caution. 1085.] From the account now given of the nature of this difeafe, it will be fufficiently obvious, that the ufe of aftringents in the beginning of it muft be abfolutely perni- cious. 1086.] Whether an acrid matter be the original caufe of this difeafe may be uncertain ; but from the indigeftion and the ftagnation of fluids in the ftomach which attend the difeafe, it may be prefumed, that fome acrid matters are * The griping is much relieved, and fometimes prevented, by drinking plentifully of any mucilaginous warm liquors during the operation of the purges ; as barley water, with bruifed prunes boiled in it. f Blifters applied to the abdomen, befides being exceflivcly troublefome, muft neceffarily be extremely painful. Pra&itioners have probably been deceived in thinking that blifters have re- lieved gripings in the dyfentery, for they are feldom employed alone ; and the effefts of purges and diluents have perhaps been miftaken for the effe&s cf a* blifter that might have happened to have been applied at the time when thefe other remedies were ufed. Too ftriet an attention to the falfe axiom, poft hoc ergo propter hoc, has been the fource of numerous errors in the pradice •f phyfie, and has raifed the reputation of the phyfician and his remedieSj when the merit was only due to nature.

At the fame time, from this confideration that mild oily matters thrown into the inteftines in confiderable quantity always prove Iaxatire, I am of opinion that the oleaginous demulcents arc the moft ufeful.* 1087. J As this difeafe is fo often of an inflammatory or of a putrid nature, it is evident that the diet employed in it fhould be vegetable and acefcent. Iviiik in its entire ftate is of doubful quality in many cafes; but fome portion of the cream is often allowable, and whey is always proper. In the firft ftages of the difeafe, the fweet and fubacid fruits are allowable, and even proper. It is in the more advanced ftages only that any morbid acidity feems to prevail in the ftomach, and to require fome referve in the ufe of acefcents. At the beginning of the difeafe, abfor- bents feem to be fuperfluous; and by their aftringent and feptic powers they may be hurtful. 1088.] When this difeafe is complicated with an inter- mittent fever, and is protraBcd from that circumftance chief- ly, it is to be treated as an intermittent, by adminiftering the Peruvian bark, which, however, in the earlier periods of the difeafe, is hardly to be admitted.

Thefe 1 again diftinguifh, as they confift, either in the interrupti- on and debility ofthe powers of fenfe and motion, or in the irregularity with which thefe powers are exercifed; and have accordingly arranged them under the four orders of Coma- ta, Adynamia:, Spasmi, and Vesanice, to be denned as we proceed to treat of. them more particularly.

I. ©fapopler?. 1093.] APOPLEXY is that difeafe in which the whole of the external and internal fenfes, and the whole of the vo- luntary motions, are in fome degree abolifhed ; while ref- piration and the action of the heart continue to be perform- ed.* By its being an affection ofthe whole of the powers of fenfe and of voluntary motion, we diftinguifh it from Palsy; and by its being with the continuance of refpirati- on and the action of the heart, it is diftinguifhed from Syn- cope. I have further added to the ordinary definition of apoplexy, that the abolition ofthe powers of fenfe and mo- tion is in some degree only ; meaning by this to imply, that under the title of Apoplexy, are here comprehended thofe difeafes which, as differing from it in degree only, cannot, with a view either to pathology or pradice, be properly diftinguifhed from it: Such are the difeafes fometimes treated of under the names of Cams, Cataphora, Coma, and Lethargus. 1094. J Apoplexy, in all its different degrees, moft com- monly aifects perfons advanced in life, and efpecially thofe above fixty years of age. It moft ufually affe£ts perfons of targe heads and fhort necks,f perfons of a corpulent habit, perfons who have palfed an indolent life and ufed a full diet, and efpecially thofe who have indulged infrequent intoxication. Men who have long labored under a frequent and copious difcharge of blood from the hemorrhoidal vef- fels, upon either the fuppreffion or fpontaneous ceafing of that difcharge, are particularly liable to be affected with apoplexy. • " The appearance of a profound and continual fleep," is by Boerhaave judicioufly added to the definition of Apcptexy. To diftinguifh between a pro- found fleep and apoplexy, which verv much reu-mble each other, is, however, extremely eafy. A man in a profound lleep may in general be roufed by the application of ftrong ftimulants to the organs of fenfe which produce no effeit on an apopledtic patient. To diftinguifh between apoplexy and a fit of drunk- ennefs is not fo eafy ; for drunken people arc fometimes incapable of being roufed by any ftimulants, remaining totally, infeniible and motionlefs. The fumes ofthe liquor with which they have been intoxicated may fometimes be difcovered by fmelling : a drunken fit may alfo be Known by the palenels of the drunken man's face, and by his manner of living. t Different authors, one of whom is Boerhaave, have fuppofed that a v\?r. tcbra is fometimes wanting, the neck conufting only of lix inftcaa cf feven vertebra:. 48 PRACTICE 1095.] This difeafe frequently comes on very fuddenly: But in many cafes it is preceded by various fymptoms fuch as frequent fits.of giddinefs, frequent headachs, a hemorrha- gy from the nofe, fome tranfitory interruption ol leein^ and hearing, fome falie vilion and hearing, fome tranfitory de- gree of numbnefs or lofs of motion in the cxticmitics. fome faltering of the tongue in fpeaking, a lofi. of memory, a frequent cirowfinefs, and frequent fits of incubus. 1096.] An attention to thefe fymptoms, and to the pre- difponcnt circumftances (1094.) will often enable us to fore fee the more violent attacks of this difeafe. 1097.] When the difeafe comes on fuddenly to a confi- derable decree, it has been frequently obferved to have been immediately induced by violent exercife, by a full and long continued infpiration; by a fit of anger ; by much external heat, efpecially that arifing from a crowed affembly of peo- ple; by warm bathing; by intoxication; by long ftooping with the head down; and by a tight ligature about the neck. The difeafe has been remarked to make its attacks moft frequently in the fpring feafon, and efpecially when the ver- nal heat fuddenly fucceeds to the winter cold. 1098.J The fymptoms denoting the prefence of this dif- eafe will be fufficiently known from the definition given (1093.) Although the whole ofthe body is affected with the lofs of fenfe and motion, it fometimes takes place more upon one fide of the body than the other ; and in that cafe the fide leaft affected with palfy is fometimes affected with convulfions. In this difeafe there is often a ftertorous breathing; and this has been faid to be a mark of the moft violent ftate of the difeafe: But it is not always prefent even in the moft complete form or moft violent degree of the difeafe. 1099. J The proximate caufe of this difeafe may be, in general, whatever interrupts the motion of the nervous pow- er from the brain to the mufcles, from voluntary motion ; or, in fo far as fenfe is affected, whatever interrups the mo- tion ofthe nervous power from the fentient extremities of the nerves ofthe brain. 1100.J Such an interruption of the motions of the ner- vous power may be occafioned, either by some compression ofthe origin of the nerves, or by something destroying the mobility of the nervous power. Both thefe caufes we muft OFPHYSIC. * 49 treat of more particularly; and, firft, of that of compref- fion, feemingly the moft frequent occafion of apoplexy, and perhaps the occafion of all thofe apoplexi.es acting from internal caufes. not.J The lofs of fenfe and motion in particular parts of the body, may be obcafioned by a compreffion, either of tie origin of certain nerves only, or ofthe fame nerves in foinc part of their courfe from the brain to the organs of fenfe and motion. Such cafes of partial compreffion will be more properly confidered hereafter ; and the affection I am now to treat of being general, it mult depend upon a very general compreffion ofthe origin of the nerves, or me- dullary portion of the brain ; and therefore this more gen- eral compreffion only is to be confidered here. 1102. J This compreffion of the origin ofthe nerves, or medullary portion of the brain, may be produced in diftjjy:- ent ways ; as, l. By external violence fracturing and preffing in a part of the cranium. 2. By tumors, fometimes foft, fometimes bony, formed in different parts of the brain, or in its membranes, and becoming of fuch a bulk as to comprefs the medullary fubftance of the brain. 3. By the blood being accumulated in the blood-veffels of the brain, and diftending them to fuch a degree as to comprefs the medullary portion of the fame. 4. By fluids effufed in different parts of the brain, or in- to the cavity of the cranium, and accumulated in fuch quantity as to occafion the compreffion we treat of. An<^ as to this laft, it is to be remarked here, that the fluids effufed may be of two kinds; that is, they may be either a portion of the common mafs of blood, poured out from red veffels ; or a portion of ferum or colorlefs fluid, poured out chiefly by exhalants. 1103.] Of thefe feveral caufes of compreffion, the firft is not to be confidered here, becaufe the removing it does not belong to our province ; and the confideration of the fecond may be omitted, as in moft inftances it is neither to be difcerned nor cured by any means yet known. The third and fourth caufes of compreffion, as they are the moft frequent, and are alfo moft properly the fubjects of our air, fo they are thofe which deferve our particular attention : SO PRACTICE and we fliall therefore endeavor to trace them further back in the feries of caufes which mav produce them. 1104.] f>otn me ftates of over diftention and of effufion may be produced by whateveHnereafes the afflux and im- petus of the blood in the arteries of the head ; fuch as vi- olent exercife, a violent fit of anger, external heat applied, or any ftrong preffure upon the defcending aorta. 1105.J But both thefe ftates of over diftention and of effufion, may alfo and feem to be more frequently produ- ced by caufes that operate by preventing the free return of the venous blood from the veffels of the head to the right ventricle of the heart. 1106. j The venous veffels of the brain are of a confor- mation ar.d diftribution fo peculiar, as to lead us to believe, that Nature intended to retard the motion of the: blood, ana"accumulate it in thefe veffels; and therefore, even very fmall additional refiftances to the motion of the blood from thefe towards the right ventricle of the heart, may ftill more readily accumulate the blood in them. Such accumulation ■will moft readily happen in advanced life, when the venous fyftem in general is in a plethoric ftate, and when this ple- thora takes place efpecially in the venous veffels of the brain. It will, in like manner, be moft apt to occur in perfons whofe heads are large with refpect to the reft of the body; and in perfons of a fhort neck, which is un- favorable to i'he return of the venous blood from the head. The accumulation of blood in the venous veffels of the brain, will alfo be moft likely to occur in perfons of a corpulent habit, either becaufe thefe may be confidered to be in a plethoric ftate, or becaufe obefity, by1 occafioning a compreffion of the blood veffels in other parts of the body, more readily fills thofe of the brain, which are en- tirely free from any fuch compreffion. 1107. J Thefe are the circumftances in the conftitution ofthe body, which, producing a {lower motion and return of the venous blood from the veffels of the head, favor an accumulation and diftention in them; and we now proceed to mention the feveral occafional caufes, which, in every perfon, may directly prevent the free return ofthe blood from the veffels of the head towards the heart. Such are, 1. Stooping down with the head, or other fituations of the body in which the head is long kept in a depending ftate, O F P H Y S I C. 51 and in which the gravity of the blood increafes the aRIux of it by the arteries, and oppofes the return of it by the veins. 2. A tight ligature about the neck, which compreffes the veins more ftrongly than the arteries. 3. Any obftruction of a confiderable number of the veins carrying the blood from the head, and more efpecially any confiderable obftruction ofthe afcending vena cava. 4. Any confiderable impediment of the free paffage of the fjlood from the veins into the right ventricle of the heart; and it is commonly by this, and the immediately preceding circumftances, that polypous concrotk>n:> in the cava, or right ventricle, are found to occafiontapoplexy.. 5. The return of blood from the veins of the head to- wards the heart, is efpecially interrupted by every circum- ftance that produces a more difficult tranfmiffion of the blood through the veffels of the lungs. It is well known, that, at the end of every expiration, fome interruption is given to the free tranfmiffion of the blood through the lungs; and that this at the fame time gives an interruption to the motion ofthe blood from the veins into the right ventricle ofthe heart. This clearly appears from that re- gurgitation ofthe blood in the veins, which occafions the alternate heaving and fubfiding that is perceived in the brain of living animals when the cranium is removed, and which is obferved to be fynchronous with the alternate mo- tions of refpiration, From this we readily perceive, that whatever occafions a difficulty in the tranfmiffion ofthe blood through the lungs, muft alfo interrupt the free return ofthe venous blood from the veffels of the head ; and muft there- fore favour, and perhaps produce, an accumulation of blood, and an over-diftcntion in thefe veffels. It is further to be obferved, that as a very full infpira- tion, continued for any length of time, occafions fuch an interruption of the free tranfmiffion of the blood through the lungs, as produces a fuffufion of face, and a manifeft turgefcence of the blood-vcffels of the head and neck ; fo every full and long continued infpiration may occafion an accumulation of blood in the veffels of the head, to a very confiderable degree. Thus, as every ftrong exertion of the mufcular force ofthe body requires, and* is attended with, a very full and long continued infpiration, we thence 53 PRACTICE learn why the violent exertions of mufcular force have been fo often the immediate or exciting caufes of apopicxy. It may alfo be remarked, that corpulency and obelity feem to operate very much, by occafioning a more diffi- cult tranfmiffion of the blood through the veffels of the lungs. It appears that in fat perfon,-, from the compref- fion of the blood veflels in many parts ofthe body, the vef- fels ofthe lungs are thereby kept very full; fo that upon the leaft increafe of bodily motion, which fends the blood falter into the lungs, a more frequent and laborious refpira- tion becomes in fuch pcrlons immediately neceflary. This fhows, tlS| in fuch perfons, the blood is not freely transmit- ted through the lungs;.a circumftance \vhich, as in other inftances, muft give a conftant refiftance to the return of blood from the veffels ofthe head, and therefore favour or occafion an accumulation of blood in them. Is the motion of the blood in the veffels of the head ren- dered flower by ftudy, care, and anxiety? 1108.] It is to be obferved further, that thefe feveral caufes (1104.—1107.) of a preternatural fulnefs in the blood veffels of the brain, may produce apoplexy in dif- ferent ways, according as the fulnefs takes place in the ar- teries or in the veins. 1109.] Accordingly, firfl, the increafed afflux of blood into the arteries of the brain, and an increafed action in thefe, may either occafion a rupture in their extremities, and thereby an effufion of red blood producing compref- fion; or the fame aiilux and increafed action may occa- fion an increafed exhalation from their extremities, of a ferous fluid, which, if not as quickly re-abforbed, may foon accumulate in fuch quantity as to produce compreffion. 1110.] Secondly, The plethoric ftate of the venous vef- fels of the brain, may operate in three different ways. 1. The fulnefs of the veins may give fuch refiftance to the blood flowing into them from the arteries, as to deter- mine the impetus of the blood to be fo much greater upon the extremities of the arteries as to occafion a rupture of thefe, and confequently an effufion of red blood, or the Hazmorrhagia cerebri, which Hoffman confiders as a frequent caufe of apoplexy, and which we have before ex- plained in (771.J 2. Whilit the fame refiftance to the blood flowing from OF P FI Y S I C. -ft*- 53 the arteries into the veins, increafes the impetus of the blood to the former, this may, without occafioning rup- ture, increafe the exhalation from their exhalant extremi- ties, and produce an effufion of a ferous fluid; in the fame manner as fuch refiftance in the veins produces hydropic effufions in other parts of the body. 3. If we may fuppofe, as no lymphatics have been yet difcovered in the brain, that the ordinary abforbents are not prefent there, and that the exhaled fluids are abforbed or taken up by the extremities of the veins; this will fhow ftill more clearly that a refiftance to the motion ^he blood in the veins of the brain, may readily produce aMccurnu- lation of ferous fluid in its cavities, and confequently a compreffion producing apoplexy. 111 x.J Befides thefe caufes of apoplexy from afflux in the arteries, or refiftance in the veins, an effufion of ferum may happen from two other caufes. The one is a relaxation ofthe exhalants, as in the other cafes of hydropic diathefis prevaling in the body ; and it is not unufual for a general dropfy to end in apoplexy. The fecond is an over pro- portion of watery parts in the mafs of blood, which is there-i fore ready to run off by the exhalants, as in the cafe of an ifchuriarenalis; which, when it proves incurable, very com- monly terminates in apoplexy. 1112.J We have now mentioned the feveral caufes of apoplexy depending upon compreffion; and from the whole it will appear, that tha moft frequent of all thefe caufes is a plethoric ftate, or an accumulation and congeftion of blood in the venous veffels of the head, operating, according to its degree, in producing over-diitention or effufion. The frequent operation of fuch a caufe will efpecially appear from a confideration of the predifponent circumftances 1 (1094.) and from the antecedent fymptoms. (1095.) 1113. J From the view I have now given ofthe caufes of apoplexy arifing from compreffion, it will readily appear that there is a foundation for the common diftinction of this difeafe into the two kinds of Sanguine and Serous. But this diftinction cannot be very ufefully applied in prac- tice, as both kinds may often depend on the fame caufe, that is, a venous plethora, and therefore requiring very Dearly the fame method of cure. The only diftinction Vol. II. G- 54 ^k- ** R#A C T T C E that can dc pioperly made of apoplexies from comprcffiot:, is perhaps the diftinction of ferous apoplexv, into that de- pending on the plethora mentioned (1112.) and that de- pending on hydropic diathefis or an over proportion of water in the blood (1111,) the former caufes giving a pro- per idiopathic, the latter only a fymptomatic difeafe. ix 14.J Befide the caufes now mentioned, occasioning apoplexy by compreffion, I al ledge there are other caufes producing the fame difeafe, bv directly deftroying the mo- bility of the nervous power. iSuch caufes feem tobe the mephitiJkrifing from fermenting liquors, and from manv other foffl^cs; the fumes arifing from burning charcoal; the fumes of mercury, of lead, and of fome other metal- lic fubftances; opium, alcohol, and many other narcotic poifbns: To all which 1 would add the power of cold, of concuffion, of electricity, and of certain paffions'of the mind. 1115.J None of thefe poifons or noxious powers feem to kill by acting firft upon the organs of refpiration, or up- on the fanguiferous fyflem ; and I believe their immediate .'md direct atlion to be upon the nervous power, deftroying its mobility, becaufe the fame poifons fhow their power in deftroying the irritability of mufcles and ofthe nerves con- nected with them, when both thefe arc entirely icperated from the reft ofthe body. 1116. J It appears tome probable, that the apoplectic ftate in fome degree accompanying, and almoflPalways Suc- ceeding, an epileptic paroxyfm, does not depend upon com- preffion, but upon a certain ftate of immobility of the ner- vous power, produced by certain circumftances in the ner- vous fyftem itfelf, which fometimes feem to be commit ~ nicated from one part of the body to another, and at length to the brain. 1117.3 The fame obfervation may be made with refpect •to many inftances of hyfteric paroxyfm ; and the circum- ftances, both of epileptic and hyfteric paroxyfms, ending in coma, or a degree of apoplexy lead me to think, that al- fo the apoplexy proceeding from retrocedent or atonic gout is ofthe fame kind, or that it depends upon an immo- bility of the nervous power, rather than upon compreffion. 1118. J If may indeed happen, that as theapoplectic and gouty predifpofitions do often concur in die fame perfon; OF PHYSIC. <•" 55 fo it may confequently happen, that the apoplexy coming upon gouty perfons, may fometimes depend u]*>n com- preffion; and diffe6tions may, accordingly,*lifcover that the circumftances of fuch a cafes had preceded. But, in many cafes of apoplexy following a retrocedent, or atonic gout, no fuch antecedent or concomitant circumftances, as commonly occur in cafes of compreffion, do diftinctly or clearly appear; while others prefent themfelves, which point out an affection ofthe nervous power alone. 1119.] With refpect, however, to the circumftances which may appear upon the diffection of perfijs dead of apoplexy, there may be fome fallacy in jui^ig, from thofe circumftances, of the caufe of the difeafe. What- ever takes off or diminifhes the mobility of the nervous power, may very much retard the motion of the blood in the veffels ofthe brain; and that perhaps to the degree of increafing exhalation, or even of occafioning rupture and effufion : fo that, in fuch cafes, the marks of compreffion may appear, upon diffection, though the difeafe had truly depended on caufes deftroying the mobility ofthe nervous power. This feems to be illuitrated and confirmed from what occurs in many cafes of epilepfy. In fome of thefe, after a repetition of fits, recovered from in the ufual man- ner, a fatuity is induced, which commonly depends upon a watery inundation ofthe brain: And in other cafes of epilepfy, when fits have been often repeated without any permanent confequence, there happens at length a fatal paroxvfm; and upon difle£tion it appears, that an effufion of blood had happened. This,-1 think, is to be confider- ed as a caufe of death, not as a caufe of the difeafe: for in fuch cafes, I fuppofe that the difeafe -had diminifiVd the action of the veffels of the brain, and thereby given oc- cafion to a ftagnation, which produced the appearances mentioned. And I apprehend the fame reading will ap- ply to the cafes of retrocedent gout, which^1 deftroying the energy ofthe brain, may occafion fuch a ftagnation as will produce rupture, effufion, and death; and in fuch a cafe, the appearances upon diffection might lead us to think that the apoplexy had depended entirely upon compreffion. 1120.J The fevcral caufes mentioned in (1114.) are of- ten of fuch power as to occafionimmediate deatjp and tlierefore have not commonly bcenflken notice of as afford- 56 PRACTICE ing inftmces of apoplexy ?-but, as the operation of the whole %f thefe caufes is fimilar and analogous, and as in moft inftanc«o of the operation of thefe caufes an apoplectic ftate is manifeftly produced, there can be little doubt in confidering molt of the inftances of their effects as cafes of apoplexy, and therefore fuch as fall properly under our confideration here. 1121. J This difeafe of apoplexy is fometimes entirely recovered from; but more.frequently it ends in death, or in a hemiplegia. Even when an attack of the difeafe is re- coveredAom, we generally find it difpofed to return; and the repei^d attacks of it almoft always, fooner or later, bring on the events we have mentioned. ii22.J The feveral events of this difeafe, in health, death, or another difeafe, may be expected and forefeen from a confideration of the predifponent circumftances (1094.) of the antecedent fymptoms (1095.) of theexciting caufes (1097.) of the violence and degree of the fymp- toms when the difeafe has come on (1093.) of the duration of the difeafe; and of the effects of the remedies employed. 1123. J From the great danger attending this difeafe when it has come on (1121.) it will readily appear, that our care fliould be chiefly directed to the prevention of it. This, I think, may be often done by avoiding the remote and exciting caufes; and how this may be accomplifhed, will be obvious from ihe enumeration of thofe caufes given above (1097.) But it will alfo appear from what is faid above, that the prevention of this difeafe will efpecially depend upon obviating the predifponent caufe; which, in moft cafes, feems to be a plethoric ftate of the blood-vef- fels of the brain. This, I think, may be obviated by dif- ferent means; and, in the firft place, by a proper manage- ment of exercife and diet. 1124. J ^e exercife ought to be fuch as may fupport the perfpin^n, without heating the body or hurrying refpiration; and, therefore, commonly by fome mode of geftation. In perfons not liable to frequent fits of giddi- nefs, and who are accuftomed to riding on horfeback, this exercife is, of all others, the beft. Walking, and fome other modes of bodily exercife, may be employed with the reftrictions juft now mentioned; but in old men, and OF PHYSIC. ST in men of corpulent habits, bodily exercife ougnt always to be very moderate. • 1125.J In perfons who pretty early in lifeihow the pre- difpofition to apoplexy, it is probable that a low diet, with a good deal of exercife, might entirely prevent the difeafe; but, in perfons who are advanced in life before they think of taking precautions, and are at the fame time of a cor- pulent habit, which generally fuppofes their having been accuftomed to full living, it might not be fafe to put them Upon a low diet; and it may be enough that their diet be rendered more moderate than ufual, efpecially \ykh refpect to animal fooci| and that, at fuppcr, fuch food mould be abftained from altogether. In drinking, all heating liquors are to be abftained from, as much as former habits will allow; and the fmalleft ap- proach to intoxication is to be carefully fhunned. For ordinary draught, fmall beer is to be preferred to plain water, as the latter is more ready to occafion coftivenefs, which in apoplectic habits is to be carefully avoided. The large ufe of tobacco in any fhape, may be hurtful; and except in cafes where it has been accuftomed to occafion a copious excretion from the head, the interruption of which might not be fafe, the ufe of tobacco fhould be avoided; and even in the circumftance mentioned, where it may be in fome meafure neceffary, the ufe of it fhould at leaft be rendered as moderate as poffible. 1126.J Evacuations by ftool may certainly contribute to relieve the plethoric ftate of the veffels of the head; and, upon an appearance of any unufual turgefcence in thefe, purging will be very properly employed: But, when no fuch turgefcence appears, the frequent repetition of large purging might weaken the body too much; and, for pre- venting apoplexy, it may for the moft part be enough to keep the belly regular, and rather open, by^ gentle laxa- tives.* In the fummer feafon, it may be ufeful to drink, * Gentle laxatives have been often enumerated in the preceding notes. In thefe cafes, however, there is no danger to be apprehended from the ufe of the relinous draftics, provided that they are not given in fuch dofes as may ■weaken the patient too much. They ought not to be ufed for the purpofe of purging, but only for keeping the body moderately open; and this effeft ma/ be fafely produced by live or eight grains of Rufus's pills taken occafionally at bed-time, or by a tea-fpoonful or two of the Tinft. jalap, or a table-fpoon- ful of the elixir fenna: in the morning. The fame end may, in many cafe:,, bo anfwered by a due ittcutionto diet. 53 PRACTICE every morning, of a gcntjp laxative mineral water, but never iff'large quantity. 1127. J In the cafe of a plethoric ftate of the fyftem, it ^ might be fuppofed that bl^tfcl-letting worild be the moft | effectual means of diminifhing the plethora, and of pre- venting its confequences; and, when an attack of apo- plexy is immediately threatened, bldod-lctting is certainly the remedy to be depended upon; and blood fliould be taken largely, if it can be done, from the jugular vein, or temporal artery. But, when no threatening turgefcence \ appears,^he obviating plethora is not judicioufly attempt- ed by blood-letting, as we have endeavoured to demon- ftrate above, (786.) In doubtful circumftances, leeches applied to the temples or fcarificatious of the hind-head, may be more fafe than general bleedings. f 1128. J When there arc manifeft fymptoms of a pletho- j ric ftate in the veffels of the head, a fe.ton, or pca-iffue, near tire head, may be very ufeful in obviating any turgef- J cence of the blood. j 1129. J Thefe are the means to be employed for pre- 1 venting the apoplexy which might arile from a plethoric ftate ofthe veffels of the brain; and if, at the fame time, great care is taken to avoid the excitingcauies (1097.) I hefe means will be generally fuccefsful. In the cafes proceeding from other caufes (1114.) a-. their application is fo immediately fucceeded by the dif- A cafe, they hardly allow any opportunity for prevention. 1130.J For the Cure of apoplexies from internal cau- I fes, and which I fuppofe to be chiefly thole from comprel- 1 lion, the ufual violence and fatality of it require that the J proper remedies be immediately and largely employed. The patient is to be kept as much as poffible in fome- what of an erect pofture, and in cool air; and therefore neither in a warm chamber, nor covered with bed clothes, nor furrounded with a crowd of people. 1131. J In all cafes of a full habit, and where the difeafe has been preceded by marks of a plethoric ftate, blood- letting is to be immediately employed, and very largely. In my opinion, it will be moft effectual when the blood is taken from the jugular vein; but, if that cannot be pro- perly done, it may be taken from the arm. The opening •* of the temporal artery, when a large branch can be opened, OF PHYSIC. 5* fo as fuddenly to pour out a confiderable quantity of blood, may alio be an effectual remedy; but, in execution, it is more uncertain, and may be inconvenient. It may be in fome meafure fiipplied, by cupping and fcarifying on the temples or hind-head. This, indeed, fhould feldom be omitted; and thefe fcarifications are always preferable to the application of leeches. With refpect to every mode of blood-letting, this is to be obferved, that when in any cafh of apoplexy, it can be perceived that one fide of the body is more affected with the lofs of motion than the other, the blood-letting, if pof- fible, fliould be made on the fide oppofite to that moft affected.* 1132.J Another remedy to be employed is purging, to be immediately attempted by acrid glyfters;t and, at the fame time, if any power of fwallowing remain, by draftic purgatives given by the mouth. Thefe, however, left they may excite vomiting fliould be given in divided por- tions at proper intervals. + 1133.

This remedy I do not confider as a ftimulant, or capable of making any confiderable re- vulfion; but, applied to the head, I fuppofe it ufeful in taking off the hemorrhagic difpofition fo often prevailing there. ii35.]#It has been ufual with practitioners, together with the remedies already mentioned, to employ ftimulants of various kinds; but I am difpofed to think them gene- rally hurtful; and they muft be fo, wherever the fulnefs of the veffels, and the impetus of the blood in thefe, is to be diminifhed. Upon this principle it is therefore agreed, that ftimulants arc abfolutely improper in what is fuppofed tobe a fanguine apoplexy; but they are commonly fup- pofed to be proper in the ferous. If, however, we be right in allcdging that this alfo commonly depends upon a plethoric ftate of the blood-veflels of the brain, ftimulants muft be equally improper in the one cafe as in the other. 1136. J It may be argued from the almoft univerfal emr ployment of ftimulants, and fometimes with feeming ad- vantage, that they may not be fo hurtful as my notions of the caufes of apoplexy lead me to fuppofe. But this ar- gument is, in feveral refpects, fallacious; and particularly in this, that in a difeafe which, under every management, often proceeds fo quickly to a fatal termination, the effects of remedies are not to be eafily afcertained. 1137.] I have now mentioned the feveral remedies which I think adapted to the cure of apoplexy arifing from compreffion, and fliould next proceed to treat ofthe cure of apoplexy arifing from thofe caufes that directly deftroy the mobility of the nervous power. But many of thofe caufes are often fo powerful, and thereby fo fuddenly fatal in their effects, as hardly to allow of time for the ufe of remedies; and fuch cafes, therefore, have been fo feldom- the fubjects of practice, that the proper remedies are not fo well afcertained as to enable me to fay much of them here. 1138.] When, however, the application of the caufes, O F PH Y SIC 61 (1114.) is not fo powerful as immediately to kill^and in- duces only an apoplectic ftate, fome efforts are to be made to obviate the confequences, and to recover the patient; and even in fome cafes where the caufes referred to, from the ceafing of the pulfe and of refpiration, and from a cold- nefs coming upon the body, have induced an appearance of death; yet, if thefe appearances have not continued'^ long, there may be means of recovering the perfons to life and health. I cannot, indeed, treat this fubject com- pletely; but for the cure of apoplexy from feveral of the caufes mentioned (1114.) fhall offer the following general directions. 1. When a poifon capable of producing apoplexy has been recently taken into the ftomach, if a vomiting fpon- taneoufly arifes, it is to be encouraged; or, if it does not fpontaneoufly come on, a vomiting is to be immediately excited by art, in order that the poifon may be thrown out as quickly as poffible. If, however, the poifon has been taken into the ftomach long before its effects have appear- ed, we judge that, upon their appearance* the exciting of vomiting will be ufelefs, and may perhaps be hurtful. 2. When .the poifon taken into the ftomach, or other- wife applied to the body, has already induced an apoplec- tic ftate, as thofe caufes do commonly at the fame time oc- cafion a ftagnation or flower motion ofthe blood in the veffels ofthe brain and ofthe lungs, fo it will generally be proper to relieve this congeftion by taking fome blood from the jugular vein, or from the veins of the arm : 3. Upon the fame fuppofition of a congeftion in the brain or lungs, it will generally be proper to relieve it by means of acrid glyfters producing fome evacuation from the in- teftines. 4. When thefe evacuations by blood-letting and purg- ing have been made, the various ftimulants which have been commonly propofed in other cafes of apoplexy, may be employed here with more probability and fafety * One * The ftimulants are various according to the various parts of the body to which thevare generally applied, as volatile and vinous fpirits, or vinegar, to the nofe and temples; acrid eflential oils, mixed with thrice their weight of hog's lard, to the breaft and back ; blifters, hot finapifms, and warm fomen- tations, with horfe-radifti, to the extremities; friftions with warm bruiries; the aftual cautery to the foles of the feet, and palms of the hands ; with fe- veral others, which are more particularly defcribed in the notes on article ; 160, et feq. Vol. IU H 6? PRACTICE of thegioft effectual means of roufing apoplectics of this kind feems to be throwing cold water on feveral parts oi the body, or wafhing the body all over with it. 5. Although the poifon producing apoplexy happens to be fo powerful as very foon to occafion the appearances of death above-mentioned; yet if this ftate has not con- tinued long, the patient may often be recoverable; and the recovery is to be attempted by the fame means that are directed to be employed, for the recovery of drowned per- fons, and which are now commonly known. CHAP. II. 1139.] X ALSY is a difeafe confiffing in a lofs of the power of voluntary motion, but affecting certain parts of the body only, and by this it is diftinguifhed from apoplexy. (1093.) One ofthe moft frequent forms of palfy is when it affects the whole of the mufcles on one fide of the body; and then the difeafe is named a. Hemiplegia. 1140.] The lofs ofthe power of voluntary motion may be owing either to a morbid affection ofthe mufcles or or- gans of motion, by which they are rendered unfit for mo- tion ; or to an interruption of the influx of the nervous power into them, which is always neceffary to the motions of thofe that are under the power of the will. The difeafe,. from the firft of thefe caufes, as confifting in an organic and local affection, we refer entirely to the clafs of local dif- eafes.. I am here to confider that difeafe only which de- pends upon the interrupted influx of the nervous power; and it is to this difeafe alone I would give the appellation of Palsy. A difeafe depending on an interrupted influx of the nervous power, may indeed often appear as merely a local affection; but as it depends upon an affection of the moft general powers of the fyftem, it cannot be properly feparated from the fyftematic affections. 1141.] In palfy, the lofs of motion is often accompanied with the lofs of fenfe; but as this is not conftantly the cafej and as therefore the lofs of fenfe is not an effential fymp- tom of palfy, I have not ta| a cold watery infufion, or in an infufion in ale. The fcurvy-grafs is another of the fame clafs; it may be eaten raw, or we may give forty or fifty drops ofthe Spiritus cochlearix, O F P H Y S I a" 71 may in this way alfo be of fervice in fome cafes of ferous palfy. ■** 3. The various aromatics, whether employed in fub- ftance, in tinaure, or in their effential oils, are often pdw- erful ftimulants; but being more adhefive and inflamma- tory than thofe laft mentioned, they are therefore, in all ambiguous cafes, lefs fafe.* 4. Some other acrid vegetables have been employed; but we are not well acquainted with their peculiar virtues, or proper ufe. 5. Some refinous fubftances, as guaiacum, and the te- rebinthinate fubftances, or their effential oils, have been with fome probability, employed; but they are apt to be- come inflammatory. Decoaions of guaiacum, and fome other fudorifics, have been direaed to excite fweating by the application of the fumes of burning fpirit of wine in the laconicum, and have in that way been found ufeful. 6. Many of the feted antifpafmodic medicines have been frequently employed in palfy ; but I do not perceive in what manner they are adapted to the cure of this difeafe, and I have not obferved their good effeas in any cafes of it. 7. Bitters, and the Peruvian bark, have, alfo been em- ployed; but with no propriety or advantage that I can perceive.t 1169.] With refpea to the whole of thefe internal ftimu- lants, it is to be obferved, that they feldom prove very pow- erful ; and wherever there is any doubt concerning the na- ture or ftate of the difeafe, they may readily do harm, and are often therefore of ambiguous ufe. either on a piece of fugar, or mixed with half an ounce of fyrup, four or five times a-day. This fpirit ought to be kept well corked, as it foon loofes all its activity, if it be expofed to the air. * The aromatics belt adapted for ftimulating, in thefe cafes, are fuch as Linne calls Spirantia; the chief of them are, Marum, Rofemary, Lavender, &c. Their fpiritous waters are much more efficacious than the plants in fub- ftance, or in any other form ; and their efficacy is confiderably increafed by uniting them to volatile fpirits, as in fome of the formulae mentioned in the firft note on this article. fj In fome cafes, paralytic patients, for want of exercife, fink into a ftate of debility, with lofs of appetite, and confequent emaciation, in which bitters, Peruvian bark, and other tonics, are frequently of fome advantage.

SDf ^pncope, or jfainting. 1170.] i HIS is a difeafe in which the aaion ofthe heart and refpiiation become confiderably weaker than ufual, or in which for a certain time thefe functions ceafe altogether. 1171.] Phyficians having obferved that this affeaion oc- curs in different degrees, have endeavoured to diftinguifh thefe by different appellations -. but as it is not poffible to afcertain thefe different degrees with any precifion, fo there can be no ftritt propriety in employing thofe different names; and I fliall here comprehend the whole of the af- fections of this kind under the title of Syncope. 1172.J This difeafe fometimes comes on fuddenly to a confiderable degree, but fometimes alfo it comes on gradu- ally ; and in the latter cafe, it ufually comes on with a fenfe of langour, and of anxiety about the heart, accompanied at the fame time, or immediately after with fome giddinefs dimnefs of fight, and founding in the ears. Together with thefe fymptoms, the pulfe and refpiration become weak ; and often fo weak, that the pulfe is fcarcely to be felt, or the refpiration to be perceived ; and fometimes (hefe mo- tions, for a certain time, ceafe altogether. While thefe fymptoms take place, the face and whole furface of the body become pale, and more or lefs cold according to the degree and duration of the paroxyfm. Very commonly, at the beginning of this, and during its continuance, a cold fweat appears, and perhaps continues, on the fore- head, as well as on fome other parts of the body. During the paroxyfms, the animal funaions, both of fenfe and motion, are always in fome degree impaired, and very of- ten entirely fufpended. A paroxyfm of fyncope is often, after fome time, fpontaneoufly recovered from; and this recovery is generally attended with a fenfe of much anxiety about the heart. O F P H Y S I C. 73 Fits of fyncope are frequently attended with, or end in, vomiting; and fometimes with convulfions, or an epilep- tic fit. 1173.] Thefe are the phenomena in this difeafe; and from every view of the greateft part of them, there cannot be a doubt that the proximate caufe of this difeafe is a very weak or a total ceafing of the aaion of the heart. But it will be a very difficult matter to explain in what manner the feveral remote caufes operate in producing the prox- imate caufe. This, however, I fhall attempt, though w-ith that diffidence which becomes me in attempting a fub- jea that has not hitherto been treated with much fuccefs. 1174.] The remote caufes of fyncope may, in the firft place, be referred to two general heads. The one is, of thofe caufes exifting and acting in the brain, or in parts of the body remote from the heart, but aaing upon it by the intervention ofthe brain. The other general head of the remote caufes of fyncope, is of thofe exifting in the heart itfelf, or in parts very immediately conneaed with it, and thereby aai ng more direaiy upon it in producing this difeafe. 1175. J In entering upon the confideration ofthe firft fet of thofe caufes (1174.) I muft affume a propofition which I fuppofe to be fully eftablifhed in phyfiology. It is this: That, though the mufcular fibres of the heart be endowed with a certain degree of inherent power, they are ftill, for fuch action as is neceffary to the motion ofthe blood, very conftantly dependent upon a nervous power fent into them from the brain.* At leaft this is evident, that there are certain powers aaing primarily, and perhaps only in the brain, which influence and varioufly modify the aaion of the heart. I fuppofe, therefore, a force very conftantly during life exerted in the brain, with refpea to the moving fibres ofthe heart, as well as of every part ofthe body; which force I fhall call the energy of the brain; and which I fuppofe may be, on different occafions, ftronger or weak- er with refpea to the heart. I * The author here differs fomewhat in opinion from phyfioligifts. He al- Q "To^s, indeed, that the heart pofleffes a vis infita in a certain uegree, but he will not allow this vis infita tobe fufficiently itrongfor carrying on the circu- lation ; and he thinks that fome energy muft be imparted to the heart frcm the brain, in order to enable that important mufcle to perform its office. In tupportof this opinion, we have a plain faft, which the author might have adduced, viz. that a ligature on the nerves going to the heart immediately flops its motions. 71 PRACTICE 11 ;6J Admiring thefe propofitions, it will be obvious, that if I can explain in what manner tfie firft fet of remote .; caufes (1174.) diminifh the energy ofthe brain, I fhall at the fame time explain in what manner thefe caufes occafion g a fyncope. . n 77. J To do this, I obferve, that one ofthe moft evi- dent of the remote caufes of fyncope is a hemorrhagy, or an evacuation of blood, whether fpoiuaneous or artificial. ,, And as it u very manifeft that the energy of the brain de- pends upon a certain fulnefs and tenfion of its blood-veffels, ' for which nature feems to have induftrioufly provided by fuch a conformation of thofe blood-veflels as retards the motion of the blood both in the arteries and veins of the brain; fo we can readily perceive, that evacuations of blood, by taking off the fulnefs and tenfion ofthe blood-veffels of the brain, and thereby diminifhing its energy with refpect to the heart, may occafion a fyncope. In many perfons, a fmall evacuation of blood will have this effea; and in *.. fuch cafes there is often a clear proof of the manner in which the caufe operates, from this circumftance, that the i effea can be prevented by laying the body in a horizontal M pofture; which, by favoring the afflux ofthe blood by the i arteries, and retarding the return of it by the veins, pfle- ferves the neceffary fulnefs ofthe veffels ofthe brain. It is farther to be remarked here, that not only an eva- I cuation of blood occafions fyncope, but that even a change 4 j in the diftribution of the blood, whereby a larger portion gJ of it flows into one part of the fyftem of blood-veffels, and J confequently lefs mto other, may occafion a fyncope. It wk is thus I explain the fyncope that readily occurs upon the evacuation of hydropic waters, which had before filled the cavities of the abdomen or thorax. It is thus alfo I ex-. j plain the fyncope that fometimes happens on bjood-letting, J but which does not happen till the ligature which had been employed is untied, and admits a larger afflux of blood in- to the blood-veffels of the arm. Both thefe cafes of fyn- fc cope fhow, that an evacuation of blood does not always occafion the difeafe by any general effea on the whole fyf- tem, but often merely by taking off the requifite fulnefs of the blood-veffels of the brain. 1178.J The operation of fome others of the remote ■caufes of fyncope, may be explained on the following prin- OF P PI Y S I C. ciples. Whilft the energy of the brain is, upon^differcnt occafions, manifeftly ftronger or weaker, it feems to be with this condition, that a ftronger exertion of it is necef- farily followed by a weaker ftate of the fame. It feems to depend upon this law in the conftitution ofthe nervous p.ow- cr, that the ordinary contraaion of a mufclc is always al- ternated with a relaxation ofthe fame; that, unlefs a con- traaion proceeds to the degree of fpafm, the contraaed ftate cannot be long continued; and it feems to depend up- on the fame caufe that the voluntary motions which al- ways require an unufual increafe of exertion, occafion fatigue, debility, and at length irrefiftible fleep. From this law, therefore, ofthe nervous power, wc may underftand why a fudden and violent exertion of the ener- gy of the brain is fometimes followed by fuch a diminution of it as to occafion a fyncope; and it is thus I fuppofe that a violent fit of joy produces fyncope, and even death. It is upon the fame principle alfo, I fuppofe, that an exqui- fitc pain may fometimes excite the energy ofthe brain more ftrongly than can be fupported, and is therefore followed by fuch a diminution as muft occafion fainting. But the effe6t of this principle appears more clearly in this, that a fainting readily happens upon the fudden remiffion of a confiderable pain; and thus I have feen a fainting occur upon the redu&ion of a painful diflocation. " 1179.] It feems to be quite analogous when a fyncope immediately happens on the finifhing of any great and long- continued effort, whether depending on the will, or upon a propenfity; and in this way a fainting rbmetimes happens to a woman on the bearing of a child. This may be well illuftrated by obferving, that in perfons already much weak- ened, even a very moderate effort will fometimes occafion fainting. 1180.] To explain the operation of fome other caufes of fyncope, it may be obferved, that as the exertions of the energy of the brain are efpecially under the influence of the will, fo it is well known that thofe modifications of A the will which are named Paffions and Emotions, have a powerful influence on the energy of the brain in its aaions upon the heart, either in increafing or diminifhing the force of that energy. Thus, anger has the former, and fear the latter effett; and thence it may be underftood how terror 76 PRACTICE often occafions a fyncope fometimes of the moft violent kind, named Afphyxia, and fometimes death itfelf. 1181.] As, from what I have juft mentioned, it appears, that the emotions of defire increafe, and thofe of averfion diminifh, the energy ofthe brain; fo it may be underftood, how a ftrong averfion, a horror, or the feeling which arifes upon the fight of a very difagreeable objea, may occafion fainting. As an example of this, I have known more than one inftance of a perfon's fainting at the fight of a fore in another perfon. 1182.] To this head of horror and difguft, I refer the operation of thofe odours which in certain perfons occa- fion fyncope. It may be fuppofed, that thofe odours arc endowed with a directly fedative power, and may thereby occafion fyncope; but they are, many of them, with ref- pea to other perfons, evidently of a contrary quality; and it appears to me, that thofe odours occafion fyncope only in thofe perfons to whom they are extremely difagreeable. 1183.] It is, however, very probable, that, among the caufes of fyncope, there are fome which, analogous to all thofe we have already mentioned, aa by a dire£lly fedative power: And fuch may either be diffufed in the mafs of blood, and thereby communicated to the brain; or may be only taken into the ftomach, which fo readily and fre- quently communicates its affeaions to the brain. 1184. J Having now enumerated, and, as I hope, ex- plained the moft part of the remote caufes of fyncope, that either operate immediately upon the brain, or whofe ope- ration upon othef parts of the body is communicated to the brain, it is proper to obferve, that the moft part of thefe caufes operate upon certain perfons more readily and more powerfully than upon others; and this circumftance, which may be confidered as the predifponent caufe of fyn- cope, deferves to be inquired into. It is in the firft place, obvious, that the operation of fome of thofe caufes depends entirely upon an idiofyncrafy in the perfons upon whom they operate ; which, however, I cannot pretend to explain. But, in the next place, with refpea to the greater part of the other caufes, their effeas feem to depend upon a temperament which is in one de- gree or other in common to many perfons. This tempe- rament feems to confift in a great degree of fenfibility and OF PHYSIC. mobility, arifing from a ftate of debility, fometimes de- pending upon original conformation, and fometimes pro- duced by accidental occurrences in the courfe of life. 1185. J The fecond fet of the remote caufes of fyncope (1174.) or thofe aaing direaiy upon the heart itfelf, are certain organic affeaions of the heart itfelf, or of the parts immediately conneaed with it, particularly the great vef- fels which pour blood into, or immediately receive it from, the cavities of the heart. Thus a dilatation or aneurrfm of the heart, a polypus in its cavities, abfeeffes or ulcera- tions in its fubftance, a clofe adherence ofthe pericardium to the furface of the heart, aneurifms of the great veffels near to the heart, polypus in thefe, and oflifications in thefe or in the valves of the heart, are one or other of them conditions which, upon diffeaion, have been difcovered in thofe perfons who had before laboured under frequent fyncope. 1186.J It is obvious, that thefe conditions are all of them, either fuch as may, upon occafion, difturb the free and regular influx into, or the free egrefs ofthe blood from, the cavities of the heart; or fuch as may otherwife difturb its regular aaion, by fometimes interrupting it, or fome- times exciting it to more violent and convulfive aaion. The latter is what is named the Palpitation of the Heart, and it commonly occurs in the fame perfons who are liable to fyncope. 1187.] It is this, as I judge, that leads us to perceive in what manner thefe organic affeaions of the heart and great veffels may occafion fyncope: for it may be fuppofed, that the violent exertions made in palpitations may either give occafion to an alternate great relaxation, (1178.) or to a fpafmodic contraaion; and in either way fufpend the aaion of the heart, and occafion fyncope. It feems to me pro- bable, that it is a fpafmodic contraaion ofthe heart that , occafions the intermiffion ofthe pulfe fo frequently accom- f. panying palpitation and fyncope. 1188.] Though it frequently happens that palpitation and fyncope arife, as we have faid, from the organic affec- tions above mentioned,, it is proper to obferve, that thefe difeafes, even when in a violent degree, do not always depend on fuch caufes aaing direaiy on the heart, but are often Vol. II. K 78 PRACTICE dependent on fome of thofe caufes which we have men- tioned above as atting primarily on the brain. 1189.J I have thus endeavored to give the pathology of fyncope; and of the cure I can treat very fhortly. The cafes of fyncope depending on the fecond fet of caufes, (1174.) and fully recited in (1185.) I fuppofe to b© generally incurable; as our art, fo far as I know, has not yet taught us to cure any of thofe feveral caufes of fyncope (1185.) The cafes of fyncope depending on the firft fet of caufes, (1174.) and whofe operation I have endeavored to explain in (1177. et. seq ) I hold to be generally curable, either by avoiding the feveral occafional ^caufes there pointed out, or by correaing the predifponent caufes (1184.) The lat- ter, I think, may generally be done by correaing the debi- lity or mobility of the fyftem, by the means which I have already had occafion to point out in another place.* CHAP.

J But as this difeafe is alfo frequently a feconda- ry and fympathic affeaion, fo the fymptoms above-men- tioned are often joined with many others; and this has giv- en occafion to a very confufed and undetermined defcrip- tion of it, under the general title of Nervous Difeafes, or under that of Chronic Weaknefs. It is proper, however, to diftinguifh them; and I apprehend the fymptoms enu- merated above are thofe effential to the idiopathic affeaion I am now to treat of. * See article 217. &c. O F P H Y S I C. 79 1192.] It is indeed to be particularly obferve^ that thefe fymptoms are often truly accompanied with a certain ftate of mind which may be confidered as a part of the idi- opathic affection : but I fhall take no further notice of this fymptom in the prefent chapter, as it will be fully and more properly confidered in the next, under the title of Hypo- chondriafis. 1193.] That there is a diftina difeafe attended always with a greater part of the above fymptoms, is rendered ve- ry probable by this, that all thefe feveral fymptoms may arife from one and the fame caufe; that is, from an imbe- cility, lofs of tone, and weaker aaion in the mufcular fibres of the ftomach; and I conclude therefore, that this imbe- cility may be confidered as the proximate caufe of the difeafe I am to treat of under the name of Dyfpepfia. 1194. J The imbecility of the ftomach, and the confe- quent fymptoms (1190.) may, however, frequently depend upon fome organic affeaion of the ftomach itfelf, as tu- mour, ulcer, or feirrhofity; or upon fome affeaion of other parts of the body communicated to the ftomach, as in gout, amenorrhcea, and, fome others. In all thefe cafes, how- 1 ever, the dyfpeptic fymptoms are to be confidered as fe- condary or fympathic affeaions, to be cured only by cur- ing the primary difeafe.—Such fecondary and fympathic cafes cannot, indeed, be treated of here; but as I prefume that the imbecility of the ftomach may often take place without either any organic affeaion of this part, or any more primary affeaion in any other part of the body; fo I fuppofe and expea it will appear, from the confideration of the remote caufes, that the dyfpepfia may be often an idiopathic affeaion, and that it is therefore properly taken into the fyftem of methodical Nofology, and becomes the fubjea of our confideration here. 1195.] There can be little doubt, that in moft cafes, the weaker aaion ofthe mufcular fibres of the ftomach, 'is the moft frequent and chief caufe of the fymptoms menti- oned in (1190.) but I dare not maintain it to be the only caufe of idiopathic dyfpepfia. There is, pretty certainly, a peculiar fluid in the ftomach of animals, or at leaft a pe- culiar quality in the fluids, that we know to be there, up- on which the folution of the aliments taken into the ftomach -chiefly depends: and it is at the fame time probable, that 80 PRACTICE the peculiar quality of the diffolving or digefting fluids may be varioufly changed, or that their quantity may be, upon occafion, diminifhed. It is therefore fufficiently probable, that a change in the quality or quantity of thefe fluids may produce a confiderable difference in the pheno- mena of digeftion, and particularly may give occafion to many of the morbid appearances mentioned in (1190.) 1196.] This feems to be very well founded, and points out another proximate caufe of dyfpepfia betide that we have already afligned: But, notwithflanding this, as the peculiar nature of the digeftive fluid, the changes which it may undergo, or the caufes by which it may be changed, are all matters fo little known, that I cannot found any praaical doarine upon any fuppofition with refpea to them; and as, at the fame time, the imbecility of the fto- mach, either as caufing the change in the digeftive fluid, or as being induced by that change, feems always to be pre- fent, and to have a great fhare in occafioning the fymp- toms of indigeftion; fo I fhall ftill confider the imbecility of the ftomach as the proximate and almoft fole caufe of dyfpepfia. And I more readily admit of this manner of proceeding; as, in my opinion, the doarine applies very fully and clearly to the explaining the whole of the prac- tice which experience fci eftablifhed as the moft fuccefsful in this difeafe. 1197.] Confidering this, then, as the proximate caufe of dyfpepfia, I proceed to mention the feveral remote caufes of this difeafe; as they are fuch, as, on different occafions, feem to produce a lofs of tone in the mufcular fibres of the ftomach. They may, I think, be confidered under two heads. The first is, of thofe which att direaiy and immediately upon the ftomach itfelf: The second is, of thofe which a6t upon the whole body, or particular parts of it, but in confequence of which the ftomach is cniefly or almoft only affeaed. 1198. J Of the firft kind are, 1. Certain fedative or narcotic fubftances taken into the ftomach; fuch as tea, coffee, tobacco* ardent fpirits, opi- um, bitters, aromatics, putrids, and acefcents. 2. The large and frequent drinking of warm water, or of warm watry liquids. OF PHYSIC. 81 3. Frequent furfeit, or immoderate repletion of the ftomach. 4. Frequent vomiting whether fpontaneoufly arifing, or excited by art. 5. Very frequent fpitting, of rejeaion of faliva. 1199.] Thofe caufes which a6t upon the whole body, or upon particular parts and funaions of it, are, 1. An indolent and fedentary life. 2. Vexation of mind, and diforderly paffions of any kind. 3. Intenfe ftudy, or clofe application to bufinefs too long continued. 4. Excefs in venery. 5. Frequent intoxication; which partly belongs to this head, partly to the former. 6. The being much expofed to moift and cold air when without exercife. 1200.] Though the difeafe, as proceeding from the laft; fet of caufes, may be confidered as a fymptomatic affec- tion only; yet as the affe6tion of the ftomach is generally the firft, always the chief, and often the only effea which thefe caufes produce or difcover, I think the affeaion of the ftomach may be confidered as the difeafe to be attend- ed to in praaice; and the more nroperly fo, as in many cafes the general debility is c Vn) be cured by reftoring the tone of the ftomach, and by remedies firft applied to this organ. 1201.J For the cure of this difeafe, we form three fever- al indications; a prefervative, a palliative, and a curative. The first is, to avoid or remove the remote caufes juft now enumerated. The second is, toremovethofefymptoms whichefpecially contribute to aggravate and continue the difeafe. And, The third is, to reftore the tone of the ftomach; that is, to correa or remove the proximate caufe of the difeafe. 1202. J The propriety and neceffity of the firft indica- tion is fufficiently evident, as the continued application, or frequent repetition of thofe caufes, muft continue the dif- eafe; may defeat the ufe of the remedies; or, in fpite of thefe, may occafion the recurrence of the difeafe. It is commonly the neglett of this indication which renders this difeafe fo frequently obftinate.—How the indication is to be executed, will be fufficiently obvious from the confi- 82 PRACTICE. deration ofthe feveral caufes: but it is proper for the prac- titioner to attend to this, that the execution is often ex- ceedingly difficult, becaufe it is not eafy to engage men to break in upon eftablifhed habits, or to renounce the pur- fuit of pleafure; and particularly, to perfuade men that thefe praaices are truly hurtful which they have often prac- tifed with feeming impunity. 1203. J The fymptoms of this difeafe which efpecially contribute to aggravate and continue it, and therefore re- quire to be more immediately correaed or removed, arc, firft, the crudities ofthe ftomach already produced by the difeafe, and difcovered by a lofs of appetite, by a knk of weight and uneafinefs in the ftomach, and particularly by the eruaation of imperfeaiy digefted matters. Another fymptom to be immediately correaed, is an unufual quantity, or a higher degree than ufual, of acidity prefent in the ftomach, difcovered by various diforders in digeftion, and by other effeas to be mentioned afterwards. The third fymptom aggravating the difeafe, and other- wife in itfelf urgent, is coftivenefs, and therefore conftant- ly requiring to be relieved. 1204. J The first of thefe fymptoms is to be relieved by exciting vomiting; and the ufe of this remedy, therefore, ufually and properly begins the cure of this difeafe. The vomiting may be excited by various means, more gentle or more violent. The former may anfwer the purpofe of evacuating the contents ofthe ftomach: but emetics, and vomiting, may alfo excite the ordinary aaion of the ftom- ach; and both, by varioufly agitating the fyftem, and par- ticularly by determining to the furface of the body, may contribute to remove the caufes of the difeafe. But thefe latter effeas can only be obtained by the ufe of emetics of the more powerful kind, fuch as the antimonial emetics ef- .pecially are.* 1205. J The second fymptom to be palliated, is an excefs of acidity, either in quantity or quality, in the contents of the ftomach. In man there is a quantity of acefcent aliments al- moft commonly taken in, and, as I think, always undergoes an acetous fermentation in the ftomach; and it is therefore that, in the human ftomach, and in the ftomachs of allani- * The formulae and dofe3 of antimonial emetics have been defcribed in a note on Article 185. OF PHYSIC. 2-3 mals ufing vegetable food, there is always found an acid prefent. This acid, however, is generally innocent, and occafions no diforder, unlefs either the quantity of it is large, or the acidity proceeds to a higher degree than ufual. But, in either of thefe cafes, the acid occafions various dif- orders, as flatulency, eruaation, heartburn, gnawing pains of the ftomach, irregular appetites and cravings, loofenefs, griping, emaciation, and debility. To obviate or remove thefe effeas aggravating and continuing the difeafe, it is not only neceffary to correa the acid prefent in the ftom- ach; but, efpecially as this acid proves a ferment deter- mining and increafing the acefeency of the aliments after- wards taken in, it is proper alfo, as foon as poffible, to cor- rea the difpofition to exceffive acidity. 1206.] The acidity prefent in the ftomach may be cor- reaed by the ufe of alkaline falts, or abforbent earths;* or by fuch fubftances, containing thefe, as can be decom- pofed by the acid of the ftomach. Of the alkalines, the cauftic is more effeaual than the mild; and this accounts for the effeas of lime-water. By employing abforbents, we avoid the excefs of alkali, which might fometimes take place. The abforbents are different, as they form a neu- tral more or lefs laxative; and hence the difference between magnefia alba and other abforbents. It is to be obferved, * No part of thepra&ice of phyfie requires more caution than the admini- ftering alkaline falts, andabforbent earths. The alkaline falts, by theircaul- tic quality, corrode the ftomach, and blunt its adlion, when taken'in too Urge quantities ; and efpecially if, from a miftaken diagnofis, no acid is in the ftomach, Lime-water is certainly preferable to the alkaline falts; its dofe may vary from two to four ounces twice a-day, according to the urgency of the cafe. The abforbent earths, as chalk, crabs eyes, fcc. if they do not meet with an acid, are apt to concrete into a hard indiffoluble mafs, by the mucus of the ftomach. Magnefia is doubtlefs, in many cafes, preferable to a cal- careous earth ; when, on account of its purgative quality, we cannot continue its ufe. Chalk is preferable to the teftaceous powders, becaufe it is free from that glutinous fubftance with which teftaceous powders abound, and which the more readily difpofes them to concrete in the ftomach. The dofe of magnefia is from £)i. to 3L twice or thrice a-day; and its purgative qua- lity may, in many cafes, be prevented, by adding to each dofe of it ten 01 fifteen grains of rhubarb, and five or fix drops of oil of anife-feed. The De ■ co&um cretaceum of the Edinburgh Pharmacopoeia is a good form for the exhibition of chalk. But chalk may be given with rhubarb and oil of anife- feeds, like magnefia. The Trochifci e creta is a convenient form for giving the chalk, had the crabs eyes been omitted. The following antacid troches are both effectual and pleafant: B:. Magnes. alb. vi. Sacch. alb. §iii.

This, however, cannot be long continued without corrupting the ftate of our blood; and as vegetable food cannot be entirely avoided, the excefs of their acefeency may in fome meafure be avoided, by choof- ing vegetable food the leaft difpofed to a vinous fermenta- tion, fuch as leavened bread and well fermented liquors, and, inftead of frefh. native acids, employing vinegar. 1208.J The acid arifing from acefcent matters in a found ftate of the ftomach, does not proceed to any high degree, or is again foon involved and made to difappear: But this does not always happen; and a more copious acidity, or a higher degree of it, may be produced, either from a change in the digeftive fluids, become lefs fit to moderate fermentation and to cover acidity, or from their not being fupplied in due quantity. How the former may be occa- fioned, we do not well underftand; but we can readily perceive that the latter, perhaps the former alfo, may proceed from a weaker aaion of the mufcular fibres ofthe ftomach. In certain cafes, fedative paffions, immediately after they arife, occafion the appearance of acidity in the ftomach which did not appear before; and the ufe of fti- mulants often correas or obviates an acidity that would otherwife have appeared. From thefe confiderations, we conclude, that the produaion and fubfiftance of acidity in the ftomach, is to be efpecially prevented by reftoring and exciting the proper aaion of it, by the feveral means to be mentioned hereafter. 1209.] But it is alfo to be further obferved, that though there are certain powers in the ftomach for pre- venting a too copious acidity, or a high degree of it, they are not however always fufficient for preventing acefeency, or for covering the acidity produced; and therefore, a^ long as vegetable fubftances remain in the ftomach, their acefeency may go on and increafe. From hence we per- ceive, that a f pecial caufe of the excefs of acidity may be, the too long retention of .acefcent matters in the ftomach; OF PHYSIC. 55 v.'hether this may be from thefe matters being of more dif- ficult folution, or from the weaknefs of the ftomach more flowly difcharging its contents into the duodenum, or from fome impediment to the free evacuation of the ftomach by the pylorus. The latter of thefe caufes we are well ac- quainted with, in the cafe of a fcirrhous pylorus, producing commonly the higheft degree of acidity. In all the inftan- ces of this feirrhofity I have met with, I have found it in- curable : But the firft of thefe caufes is to be obviated by avoiding fuch aliments as are of difficult folution; and the fecond is to be mended by the feveral remedies for exciting the aaion ofthe ftomach, to be mentioned afterwards. 1210.] The third fymptom commonly accompanying dyfpepfia, which requires to be immediately removed, is coftivenefs. There is fo much conneaion between the fe- veral portions of the alimentary canal with refpea to the periftaltic motion, that, if accelerated or retarded in any one part, the other parts of it are commonly affeaed in the fame manner. Thus, as the brifker aaion of the ftomach muft accelerate the aaion of the inteftines, fo the flower aaion of the inteftines muft in fome meafure retard that of the ftomach. It is therefore of confequence to the pro- per aaion of the ftomach, that the periftaltic motion of the inteftines determining their contents downwards, be regularly continued; and that all coftivenefs j or interrup- tion of that determination, be avoided. This may be done by the various means of exciting the aaion of the intef- tines: But it is to be obferved here, that as every confi- derable evacuation of the inteftines weakens their aaion, and is ready therefore to induce coftivenefs when the eva- cuation is over; fo thofe purgatives which produce a large evacuation, are unfit for correaing the habit of coftive- nefs. This, therefore, fhould be atlempted by medicines which do no more than folicit the inteftines to a more rea- dy difcharge of their prefent contents, without either hur- rying their aaion, or increafing the excretions made into their cavity; either of which effeas might produce a purg- ing. There are, I think, certain medicines peculiarly proper on this occafion, as-they feem toftimulate efpeci- ally the great guts, and to aa little on the higher parts of the inteftinal canal.* • Ten or fifteen grains of Pil. Ruf. anfwer this purpofe fufficiently well. Vol. II. h 6€ PRACTICE 1211.] We have thus mentioned the feveral means of executing our fecond indication; and I proceed to the third, which is, as we have laid, the proper curative; and it is to reftore the tone of the ftomach, the lofs of which we confider as the proximate caufe of the difeafe, or at leaft as the chief part of it. The means of fatisfying this indication we refer to two heads. One is, of thofe means which operate direaiy and chiefly on the ftomach itfelf; and the other is, of thofe means which, operating upon the whole fyftem, have their tonic effefts thereby commu- nicated to the ftomach. 1212. J The medicines which operate direaiy on the fto- mach are either ftimulants or tonics. The ftimulants are faline or aromatic. The faline are acids or neutrals. Acids of all kinds feem to have the power of ftimulat- ing the ftomach, and therefore often increafe appetite: But the native acids, as liable to fermentation, may otherwife do harm, and are therefore of ambiguous ufe. The acids, therefore, chiefly and fuccefsfully employed are the vitri- olic,* muriatic,t and the diftilled acid of vegetables, as it is found in tar-water, which are all of them antizymics.+ The neutral falts anfwering this intention are efpecially thofe which have the muriatic acid in their compofition, r though k is prefumed that neutrals of all kinds have more or lefs of the fame virtue.|{ 1213. J The aromatics, and perhaps fome other acrids, certainly ftimulate the ftomach, as they obviate the acef- eency and flatulency of vegetable food: but their ftimulus is tranfitory; and if frequently repeated, and taken in large quantities, they may hurt the tone of the ftomach.** It is to be-regretted that the Author did not mention thofe certain medicine* to which he alludes. * The dofe of the vitriolic acid ought not to exceed ten drops*, and it fhould be well diluted with water. t The Tki&ura, Martis of the Edinburgh College powerfully ftimulates the ftomach, and acts at the fame time as a tonic; its dofe is from ten to twenty drops thrice a-day, in a fuiEcient quantity of any proper liquid, and it is a very agreeable medicine. $ I. e. refift fermentation. || The Sal digeftivus, i. e. the muriatic acid faturated with vegetable fixed alkali, was thought to be preferable to common fait in promoting digeftion. Hence its old name of Sal digeftivus. Its Cuperiority over common fait is however doubtful. ** This caution againft the too free ufe of aromatics ought to be peculiarly attended to by the young praftitioner. The fpeedy relief which they procure tempts the patient to have frequent recourfe to them, which, as the Author. OF PHYSIC. 87 1214.] The tonics emplbyed to ftrengthen the ftomach are bitters, bitters and aftringents combined, and chaly- beates. Bitters are undoubtedly tonic medicines, both with ref- pea to the ftomach and the whole fyftem: But their long- continued ufe has been found to deftroy the tone of the ftomach and ofthe whole fyftem ; and, whether this is from the mere repetition of their tonic operation, or from fome narcotic power joined with the tonic in them', I am uncertain. 1215.J Bitters and aftringents comJbined are prpbably more effeaual tonics than either of them takervfingly ; and we fuppofe fuch a combination to take place in the Peru- vian bark; which therefore proves a powerful tonft,' *ltath with refpea to the ftomach and to the whole fyftem. But I have fome ground to fufpea that the long continued ufe of this bark may, like bitters, deftroy, both the tone of the ftomach and ofthe whole fyftem.* 1216.] Chalybeates may be employed as tonics in vari- ous forms,t and in confiderable quantities, with fafety. They have been often employed in the form of mineral wa- ters, and feemingly with fuccefs : But, whether this is ow- ing to the chalybeate in the compoiition of thefe waters, or to fome other circumftances attending their ufe, I dare not pofitively determine; but the latter opinion feems to me the more probable. 1217. J The remedies which ftrengthen the ftomach, by being applied to the whole body, are, exercife, and the ap- plication of cold. As exercife ftrengthens the whole body, it muft alfo ftrengthen the ftomach but it does this alfo in a particular manner, by promoting perfpiration, and exciting the aai- on ofthe veffels on the furface ofthe body, which have a particular confent with the mufcular fibres ofthe ftomach. This particularly explains why the exercifes of geftation, though not the moft powerful in ftrengthening the whole juftly obferves, may materially hurt the tone of the ftomach, and confequent- ly increafe the difeafe which they were intended to remove. * Forms of thefe tonics may be feen in the preceding notes on Articles 981, 982, 992. f See the notes on Articles 981, 982, 992. In thefe cafes the Tindhira:' Martis, mentioned in the note on Article 1212, is as proper a form of chaly- beates as any we can ufe. Its dole is from ten to twenty drops in any pro- per vehicle. A glafs of cold fpring water, acidulated with a few drops of this tincture, is agreeable and refrefhing, and may be ufed a-, the pntirnt'3 common drink; its agreeablenefs may be conliderably increafed by adding tb, each half pint glafs, a table-fpoonful of ample cinnamon-wa:'-;. S9 PRACTICE fyftem, are, however, very powerful in ftrengthening the ftomach ; of which we have a remarkable proof in the ef- feas of failing. In ftrengthening the general fyftem, as fa- tigue muft be avoided, fo bodily exercife is of ambiguous ufe ; and perhaps it is thereby that riding on horfeback has been fo often found to be one of the moft powerful means of ftrengthening the ftomach, and thereby of curing dyfpepfia. 1218.] The other general remedy of dyfpepfia is the ap- plication of cold; which may be in two ways; that is, ei- ther by thefamplication of cold air, or of cold water. It is probable, that, in the atmofphere conftantly furrounding our bodies, a certain degree of cold, confiderably lefs than . the temperature of our bodies themfelves, is neceffary to the health of the human body. Such a degree of cold feems to ftrengthen the veffels on the furface of the body, and therefore the mufcular fibres of the ftomach. But, further, it is well known, that if the body is in exercife fufficient to fupport fuch a determination to the furface, as to prevent the cold from producing an entire conftriction of the pores; a certain degree of cold in the atmofphere, with fuch exer- cife, will render the perfpiration more confiderable. From the fharp appetite that in fuch circumftances is commonly produced, we can have no doubt, that by the application of fuch cold, the tone of the ftomach is confiderably flrength- ened. Cold air, therefore, applied with exercife, is a moft powerful tonic with refpect to the ftomach; and this ex- plains why, for that purpofe, no exercifes within doors,, or in clofe carriages, are fo ufeful as thofe in the open air. 1219.] From the fame reafoning, we can perceive, that the application of cold water, or cold bathing, while it is a tonic with refpea to the fyftem in general, and efpecially as exciting the action of the extreme veflels, muft in both re- fpeas be a powerful means of ftrengthening the tone of the ftomach. 1220. J Thefe are the remedies to be employed towards a radical cure of idiopathic dyfpepfia; and it might be, perhaps, expeaed here, that I fhould treat alfo of the vari- ous cafes of the fympathic difeafe. But it will be obvious that this cannot be properly done without treating of all the difeafes of which dyfpepfia is a fymptom, which cannot be proper in this place. It has been partly done already, and will be further treated of in the courfe of this work. In OF PHYSIC. *9 the mean time, it may be proper to obferve, that there is not fo much occafion for diftinguifh ing between the idiopa- thic and fympathic dyfpepfia, as there is in many other cafes of idiopathic and fympathic difeafes. For, as the fympa- thic cafes of dyfpepfia are owing to a lofs of tone in fome other part of the fyftem, which is from thence communi- cated to the ftomach ; fo the tone of the ftomach reftored, may be communicated to the part primarily affeaed; and therefore the remedies of the idiopathic may be often ufe- fully employed, and are often the remedies chiefly em- ployed in fympathic dyfpepfia. 1221. J Another part of our bufinefs here might be to fay, how fome other of the urgent fymptoms, befides thofe above-mentioned, are to be palliated. On this fubjea, I think it is enough to fay, that the fymptoms chiefly requir- ing to be immediately relieved, are flatulency, heartburn, o- ther kinds of pain in the regionofthe ftomach, and vomiting. The dyfpeptic are ready to fuppofe that the whole of their difeafe confifts in a flatulency. In this it will be ob- vious that they are miftaken; but, although the flatulency is not to be entirely cured, but by mending the imbecility of the ftomach by the means above-mentioned; yet the fla- tulent diftention of the ftomach may be relieved by carmi- natives, as they are called, or medicines that produce a dif- charge of wind from the ftomach; fuch are the various antif- pafmodics, of which the moft effeaual is the vitriolic aether. The heartburn may be relieved^by abforbents,* antif- pafmodics,t or demulcents.J The other pains of the ftomach may be fometimes re- lieved by carminatives,|| but moft certainly by opiates: * The abfoiSents have been defcribe I a&ove, fee note on Article 1206. •f It may be doubtful whether antifpafmodics are effectual in removing heartburn. Opium undoubtedly often gives relief in dofes of twenty or thir- ty drops of laudanum. | Extract of liquorice is as good a demulcent in thefe cafes as^any in the lift of the Materia Medica. Sucking a little piece of it, and drinking a. cup or two of weak lintfeed-tea after it, feldom fail of giving relief. |j Carminatives fuitable in thefe cafes are the ellential oils of the feeds of fome aromatic umbiliferous plants, as 01. Anifi. the dofe of which is t.fteen or twenty drops on a piece of fugar, though common practice feldom goes half that length. The Oleum Carvi is another excellent carminative, but it is very hot, and its" dofe muft never exceed five drops; two drops are a mo- derate dofe. The Oleum Mentha: is another good carminative ; its dofe is two or three drops on a piece of fugar. Two "Tains of the Extraft of opiun., or forty drops of the laudanum, are ufually given in half a cupful of liuturec•- tea.

A langour, liftlcffnefs, or want of refolution and aaivity . with refpeft to all undertakings; a difpofition to feriouf- nefs, fadnefs, and timidity; as to all future events, an ap- prehenfion of the worft or moft unhappy ftate of them> and therefore, often upon ftight grounds, an apprehenfion of great evil. Such perfons are particularly attentive to the ftate of their own health, to even the fmalleft change of feeling in their bodies; and from any unufual feelingy perhaps of the fiighteft kind, they apprehend great danger, and even death itfelf. In refpea to all thefe feelings and apprehenfions, there is commonly the moft obftinate belief and perfuafion. 1223.] This ftate of mind is the Hypochondriafis of medical writers. See Linnaei Genera Morborum, Gem 76. et Scgari Syftema Symtomaticum, Clafs XIII. Gem Vfs.;. The fame ftate of mind is what has been commonly c«flled Vapours and fyzo Spirits. Though the term Va- pours may be founded on a falfe theory, and therefore im- proper, I beg leave, for a pupofe that will immediately ap- pear, to employ it for a little here. 1224.] Vapours, then, or the ftate of mind defcribed above, is, like every other ftate of mind, conneaed with a certain ftate of the body, which muft be inquired into in orde£to its being treated as a difeafe by the art of phytic- 1225.] This ftate of the body, however, is not very ea- fily afcertained: for we can perceive, that on different oc- cafions it is very different; vapours being combined fome- times with dyfpepfia, fometimes with hyfteria, and fome- times vith melancholia, which are difeafes feemingly de- pending on very different ftates of the body. 1226.] The combination of vapours with dyfpepfia is very frequent, and in feemingly very different circumftan- OF PHYSIC SI == ?r ■' ces.

Firft, as the difeafe occurs , in young perfons of both fexes, in perfons of a fanguine temperament, and of a lax and flaccid habit? Secondly, as it occurs in elderly perfons of both fcxes, of a melan- cholic temperament, and of a firm and rigid habit. 1227.] Thefe two different cafes of the combination of vapours and dyfpepfia, I confider as two diftina dif- eafes, to be diftinguifhed chiefly by the temperament pre- vailing in the perfons affeaed. As the dyfpepfia of fanguine temperaments is often with- • out vapours; and as the vapours when joined with dyfpep- fia in fuch temperaments, may be confidered as, perhaps,. always a fymptom ofthe affeaion of the ftomach; fo to» this combination of dyfpepfia and vapours, I would ftill apply the appellation of Dyspepsia, and confider it as ftria- iy the difeafe treated of in the preceding chapter. But the combination of dyfpepfia and vapours in me- lancholic temperaments, as the vapours or the turn of mind peculiar to the temperament, nearly that defcribcd above in (1222.) are effential circumftances ofthe difeafe; and as this turn of mind is often with few, or only flight fymp- toms of dyfpepfia; and, even though the latter be attend- ing, as they feem to be rather the effeas of the general tem- perament, than of any primary or topical affeaion of the ftomach; I confider this combination as a very different difeafe from the former, and would apply toit ftriaiy the appellation of Hypochondriasis. 1228.] Having thus pointed out a diftinaion between- Dyfpepfia and Hypoehondriafis, I fliall now, ufing thefe terms in the ftria fenfe above mentioned, make fome obfer- vations which may, I think, illuftrate the fubjea, and more clearly and fully eftablifh the diftinaion propofed. 1229.] The dyfpe*piki often appears early in life, and i^ frequently much mended as life advances: But the hypo- chondriacs feldom appears early in life, and more ufually in more advanced years only; and more certainly ftill, when it has once taken place, it goes on increafing as lite- advances to old age. This feems to be particularly well illuftrated, by our oh ferving the changes in the ftate of the mind which ufual:;. -92 P R A C T I c r take place in the courfe of life. In youth, the mind ii J ichearful, aaive, rafh, and moveable : But, as life advances* ■ the mind by degrees becomes more ferious, flow, cautious, ^ and fteady ; till at length, in old age, the gloomy, timid^ diftruftfui,and obftinate ftate of melancholic temperaments, is more exquifitely formed. In producing thefe changes, it is true, that moral caufes have a fhare; but it is at the fame time obvious, that the temperament of the body de- termines the operation of thefe moral caufes, fooner of later, and in a greater or leffer degree, to have their effects. The fanguine temperament retains longer the charaaer of . youth, while the melancholic temperament brings on more early the manners of old age. 1230.] Upon the whole, it appears, that the ftate ofthe mind which attends, and efpecially diftinguifhes hypochon- driafis, is the effea of that fame rigidity of the folids, tor. por of the nervous power, and peculiar balance between the arterial and venous fyftcms which occur in advanced ^ life, and which at ail times take place more or lefs in melan- cholic temperaments. If therefore there be alfo fome- what of a like ftate of mind attending the dyfpepfia which occurs early in life in fanguine temperaments and lax ha- bits, it muft depend upon a different ftate of the body, and probably upon a weak and moveable ftate of the ner- vous power. i 1231.J Agreeable to all this in dyfpepfia, there is more of fpafmodic affeaion, and the affeaion ofthe mind (1 222.} \ is often abfent, and, when prefent, is perhaps always of a fiighter kind ; while in hypochondriafis the affection of the mind is more conftant. and the fymptoms of dyfpepfia, or the affeaions of the ftomach, are often abfent, or, when prefent, are in a fiighter degree. I believe the affeaion of the mind is commonly different in the two difeafes. In dyfpepfia, it is often languor and timidity only, eafily difpelled; while, in hypochondriafis, it is generally the gloomy and rivetted apprehenfion of evil. The two difeafes are alfo diftinguifhed by fome other circumftances. Dyfpepfia, as I have faid, is often a fymp- tomatic affeaion; while hypochondriafis is, perhaps, al- ways a primary and idiopathic difeafe. As debility may be induced by many different caufes^ OF PHYSIC* *3 dyfpepfia is a frequent difeafe; while hypochondriafis, de- pending upon a peculiar temperament, is more rare. 1232.] Having thus endeavoured to diftinguifh the two difeafes, I fuppofe the peculiar nature and proximate caufe of hypochondriasis will be underftood; and I proceed, therefore, to treat of its cure. So fcr as the affeaions of the body, and particularly of the ftomach, are the fame here as in the cafe of dyspepsia^ the method of cure might be fuppofed to be alfo the fame; and accordingly the praaice has been carried on with little diftinaion: But I am perfuaded that a diftinaion is often neceffary. 1233.] There may be a foundation here for the fame prefervative indication as firft laid down in the cure of dys- pepsia; (1202.) but I cannot treat this fubjea fo clearly or fully as I could wifh, becaufe I have not yet had fo much opportunity of obfervation as I think neceffary to afcertain the remote caufes; ann I can hardly make ufe of the obfervation of others, who have feldom or never diftin- guifhed between die two difeafes. What, indeed has been laid with refpea to the remote caufes of melancholia, will often apply to the hypochondriasis*, which I now treat of; but the fubjea of the former has been fo much involved in a doubtful theory, that I find it difficult to felea the faas that might properly and ftriaiy apply to the latter. I delay this fubjea, therefore, till another occafion; but in the mean time truft, that what I have faid regarding the nature ofthe difeafe, and fome remarks I fhall have occa- fion to offer in confidering the method of cure, may in fome meafure fupply my deficiency on this fubjea of the remote caufes. 1234.] The second indication laid down in the cure of dyfpepfia (1201.) has properly a place here; but it is ftill to be executed with fome diftinaion. 1235.] An anorexia, and accumulation of crudities in the ftomach, does not commonly occur in hypochondriafis as in dyfpepfia; and therefore vomiting (1204.) *s not fo often neceffary in the former as in the latter. 1236.] The fymptom of excefs of acidity, from the flow evacuation of the ftomach in melancholic temperaments, often arifes to a very high degree in hypochondriafis; and Vol. II. M 94 PRACTICE therefore, for the fame reafon as in (1205.) it is to be ob- viated and correaed with the utmoft care. It is upon this account that the feveral antacids, and the other means of obviating acidity, are to be employed in hypochondriafis, and with the fame attentions and confiderations as in (1206.) and following; with this refleaion, however, that the exr citing1 the aaion of the ftomach there mentioned, is to be a little differently underftood, as fliall be hereafter ex- plained. 1237. J As coftivenefs, and that commonly to a confi- derable degree, is a very conftant attendant of hypochon- driafis, fo it is equally hurtful as in dyfpepfia. It may be remedied by the fame means in the former as in the latter, and they are to be employed with the fame rcftriaions a3 in (1210.) 1238.] It is efpecially with refpea to the third indica- tion laid down in the cure of dyfpepfia (1201.) that there is a difference of praaice to be obferved in the cure of hy- pochondriafis; and that often one direaiy oppofite to that in the cafe of dyfpepfia, is to be followed. 1239.] In dyfpepfia, the chief remedies are the tonic medicines, which to me feem neither neceffary nor fafe in hypochondriafis; for in this there is not a lofs of tone, but a want of aaivity that is to be remedied. Chalybeate mineral waters have commonly been em- ployed in hypochondriafis, and feemingly with fuccefs. But this is probably to be imputed to the amufement and exercife ufually accompanying the ufe of thefe waters, ra- ther than to the tonic power of the fmall quantity of iron which they contain. Perhaps the elementary water, by favouring the excretions, may have a fhare in relieving the difeafe. 1240.] Cold bathing is often highly ufeful to the dyf- peptic, and, as a general ftimulant, may fometimes feem ufeful to the hypochondriaic; but it is not commonly fo to the latter; while, on the other hand, warm bathing, hurt. fui to the dyfpeptic, is often extremely ufeful to the hypo- chondriac. 1241.J Another inftance of a contrary praaice necef- fary in the two difeafes, and illuftrating their refpeaive na- tures, is, that the drinking tea and coffee is always hurtful 0 F P H Y S I C. 95 to the dyfpcptic, but is commonly extremely ufeful to the hypochondriac. 1242.] Exercife, as it ftrengthens the fyftem, and thereby the ftomach, and more efpecially, as by increafing the perfpiration, it excites the aaion of the ftomach, it proves one of the moft ufeful remedies in dyfpepfia; and further, as, by increafing the perfpiration, it excifes the aaivity of the ftomach, it likewife proves an ufeful reme- dy in the hypochondriafis. However, in the latter cafe, as I fhall explain prefently, it is ftill a more ufeful reme- dy by its operation upon the mind than by that upon the body. 1243.] It1S now proper that we proceed to confider the moft important article of our praaice in this difeafe, and which is, to confider the treatment of the mind; an affec- tion of which fometimes attends dyfpepfia, but is always the chief circumftance in hypochondriafis. What I am to fuggeft here, will apply to both difeafes; but it is the hy- pochondriafis that I am to keep moft conftantly in view. 1244..] The management ofthe mind in hypochondriacs, is often nice and difficult. The firm perfuafion that gene- rally prevails in fuch patients, does not allow their feelings to be treated as imaginary, nor their apprehenfion of dan- ger to be confidered as groundlefs, though the phyfician may be perfuaded that it is the cafe in both refpeas. Such patients, therefore, are not to be treated either by raillery, or by reafoning. It is faid to be the manner of hypochondriacs to change often their phyfician; and indeed they often do it confift- ently ; for a phyfician who does not admit the reality of the difeafe, cannot be fuppofed to take much pains to cure it, or to avert the danger of which he entertains no ap- prehenfion. If inany cafe the pious fraud of a placebo be allowable, it feems to be in treating hypochondriacs ; who, anxious for relief, are fond of medicines, and, though often difap- pointed, will ftill tafte every new drug that can be propo- fed to them. 1245.] As it is the nature of man to indulge every pre- fent emotion, fb the hypochondriac cherifhes his fears; and, attentive to every feeling, finds in trifles light as air a ftrong confirmation of his apprehenfions. His cure, 96 P R A C T I C E therefore, depends efpecially upon the interruption of his attention, or upon its being diverted to other objeas than his own feelings. 1246.3 Whatever averfion to application of any kind may appear in hypochondriacs, there is nothing more per- nicious to them than abfolute icilcnefa, or a vacancy from all eameft purfuit. It is owing to wealth admitting of in- dolence, and leading to the purfuit of tranfitory and unfa- tisfying amufements, or to that of exhaufting pleafurrs only, that the prefent times exhibit to us fo many inftances of hypochondriacifm. The occupations of bufinefs fuitable to their circum- ftances and iituation in life, if neither attended with emo- tion, anxiety, nor fatigue, are always to be admitted, and periifted in by hypochondriacs. But occupations upon which a man's fortune depends, and which are always, therefore, objeas of anxiety to melancholic men; and more particularly where fuch occupations are expofed to accidentalftnterruptions, difappointments, and failures, it is from mefc that the hypochondriac is certainly to be withdrawn. 1247.J The hypochondriac who is not neceffarily, by circumftance or habits, engaged in bufinefs, is to be drawn from his attention to his own feelings by fome amufement. The various kinds of fport and hunting, as purfued wTith fome ardour, and attended with exercife, if not too violent, are amongft the moft ufeful. All thofe amufements which are in the open air, joined with moderate exercife, and requiring fome dexterity, are generally of ufe. Within doors, company which engages attention, which is willingly yielded to, and is at the fame time of a chear- ful kind, will be always found of great fervice. Play, in which fome fkill is required, and where the ftake is not an objea of much anxiety, if not too long pro- traaed, may often be admitted. In dyipeptics, however, gaming, liable to fudden and confiderable emotions, is dangerous; and the long conti- nuance of it, with night watching, is violently debilitating. But in melancholies, who commonly excel in fkill, and are lefs fufceptible of violent emotions, it is more admiffible^ and is often the only amufement that can engage them. OF PHYSIC. 97 Mufic, to a nice ear, is a hazardous amufement, as long attention to it is very fatiguing. 1248.] It frequently happens, that amufements of every kind are rejeaed by hypochondriacs; and in that cafe, me- chanical means of interrupting thought are the remedies to be fought for. Such is to be found in brifk exercife, which requires fome attention in the condua of it. Walking is feldom of this kind; though, as gratifying to the reftleffne fs of hypochondriacs, it has fometimes been found ufeful. The required interruption of thought is beft obtained by riding on horfeback, or in driving a carriage of any kind. The exercife of failing, except it be in an open boat, engaging fome attentidh, does very little fervice. Exercife in an eafy carriage, in the direaion of which the traveller takes no part, unlefs it be upon rough roads, or driven pretty quickly, and with long continuance, is of little advantage. 1249.] Whatever exercife may be employed, it will be * moft effeaual when employed in the purfuit of a journey; firft, becaufe it withdraws a perfon from many objeas of uneafinefs and care which might prefent themfel ves at home; fecondly, as it engages in more conftant exercife, and in a greater degree of it than is commonly taken in airings a- bout home; and laftly, as it is conftantly prefenting new objeas which call forth a perfon's attention. 1250.] In our fyftem of Nofology we have, next to Hy- pochondriafis, placed the Chlorofis, becaufe I once thought it might be confidered as a genus, comprehending, befides the Chlorofis of Amenorrhcea, fome fpecies of Cachexy: But, as I cannot find this tobe well founded, and cannot diftinttly point out any fuch difeafe, I now omit confidering Chlorofis as a genus here; and, as a fymptom of Amenorrhcea, I have endeavoured before to explain it under that title. BOOK III. Of Spasmodic Affections without Fever. 1251.] U NDER this title I am to comprehend all the difeafes which confift in motu abnormi; that is, in a pre- 9* PRACTICE ternatural ftate of the contraaion and motion of the muf- cular or moving fibres in any part ofthe body. 1252.] It will hence appear, why, under this title, I have comprehended many more difeafes than Sauvages and Sagar have comprehended under the title of fpafmi, or that Linnaeus has done under the title of Motorii. But I expea it will be obvious, that, upon this occafion, it would not be proper to confine our view to the affeaions of the voluntary motion only; and if thofe Nofologifts have introduced into the clafs of Spafmi, Palpitatio and Hyfteria, it will be with equal propriety that Afthma, Co- lica, and many other difeafes, are admitted. 1253.] It has been hitherto the method of our Nofolo- gifts to divide the Spafmi into the tfro orders of Tonici and Clonici, Spaftici and Agitatorii; or, as many at prefent ufe the terms, into Spafms ftriaiy fo called, and convul- fions. I find, however, that many, and indeed moft of the difeafes to be confidered under our title of Spafmodic af- feaions, in refpea of tonic or Clonic contractions, are of a mixed kind: and, therefore, I cannot follow the ufual general divifion; but have attempted another, by arrang- ing the feveral Spafmodic difeafes according as they affea the feveral funaions, Animal, Vital, or Natural. Sect. I. Of the Spasmodic Affections of the Animal Functions, 1254.] AGREEABLE to the language of the ancients, the whole of the difeafes to be treated of in this feaion might be termed spasmi; and many ofthe moderns continue to apply the term in the fame manner : but I think it con- venient to diftinguifh the terms of Spasm and Convulsion, by applying the former, ftriaiy to what has been called the Tonic ; and the latter, to what has been called the Clonic Spafm. There is certainly a foundation for the ufe of thofe different terms, as there is a remarkable difference in the ftate of the contraaion of moving fibres upon differ- ent occafions. This I have indeed pointed out before in my treatife of Phyfiology, but mult alfo repeat it here. 1255.] In the exercife of the feveral fun6tions of the animal ceconomy, the contraaions ofthe moving fibres are excited by the will, or by certain other caufes fpecially ap- pointed by nature for exciting thofe contraaions; and thefe OFPHYSIC. 99 other caufes I name the natural causes. In a ftate of health, the moving fibres are contraaed by the power of the will, and by the natural causes only. At the fame time the contraaions produced are in force and velocity regulated by the will, or by the circumftances ofthe natural caufes; and the contraaions, whether produced by the one or the other, are always foon fucceeded by a ftate of relaxation* and are not repeated but when the power of the will or of the natural caufes is again applied. 1256.j Such are the conditions ofthe aaion ofthe mov- ing fibres in a ftate of health; but in a morbid ftate the contraaions of the mufcles and moving fibres ordinarily depending upon the will are excited without the concur- rence of the will, or contrary to what the will intends; and in the other funaions they are excited by the aaion of un- ufual and unnatural caufes. In both cafes, the contrac- tions produced may be in two different ftates. The one is, when the contra6tions are to a more violent degree than is ufual in health, and are neither fucceeded by a fpontane- ous relaxation, nor even readily yield to an extenfion ei- ther from the aaion of antagonift mufcles, or from other extending powers applied. This ftate of contraaions is what has been called a tonic spasm, and is what I fhall name fimply and ftriaiy a spasm. The other morbid ftate of contraaion is, when they are fucceeded by a relaxation, but are immediately again repeated without the concurrence ofthe will or ofthe repetition of natural caufes, and are at the fame time commonly, with refpea to velocity and force, more violent than in a healthy ftate. This ftate of morbid contraaion is what has been named a clonic spasm, and what I fhall name fimply and ftriaiy a convulsion. In this fec\ion I fhall follow nearly the ufual divifion of the fpafmodic difeafes into thefe confifting in Spafm, and thofe confifting in Convulfion; but it may not perhaps be in my power to follow fuch divifion exaaiy. CHAP. I. fl)f Cetanug* 1257.] JJOTH Nofologifts and Praaical Writers have diftinguifhed Tetanic complaints into the feveral fpecies of iOO PRACTICE Tetanus, Opifthotonos, and Emprofthotonos; and I have in my Nofology put the Trifmus, or Locked Jaw, as a genus diftina from the Tetanus. All this, however, I now judge tobe improper; and am of opinion that all the feveral terms mentioned denote, and are applicable only to, different degrees of one and the fame difeafe; the hif- tory and cure of which I fnall endeavour to deliver in this chapter. 1258.]Tetanic complaints may, from certain caufes, oc- cur in every climate that we are acquainted with ; but they occur moft frequently in the warmeft climates, and molt commonly in the warmeft feafons of fuch climates. Thefe complaints affea all ages, fexes, temperaments, and com- plexions. The caufes from whence they commonly pro- ceed, are cold and moifture applied to the body while it is very warm, and efpecially the fudden viciffitudes of heat and cold. Or, the difeafe is produced by punaures, la- cerations, or other lefions of nerves in any part of the bo- dy. There are, probably, fome other caufes of this dif- eafe; but they are neither diftinaiy known, nor well afcer- tained. Though the caufes mentioned do, upon occafion, affea all forts of perfons, they feem however to attack perfons of middle age more frequently than the older or younger, the male fex more frequently than the female, and the robuft and vigorous more frequently than the weaker. 1259.] If the difeafe proceed from cold, it commonly comes on in a few days after the application of fuch cold; but, if it arife from a punaure or other lefion of a nerve, the difeafe does not commonly come on for many days af- ter the lefion has happened, very often when there is nei- ther pain nor uneafinefs remaining in the wounded or hurt part, and very frequently when the wound has been entire- ly healed up. 1260. J The difeafe fometimes comes on fuddenly to a violent degree, but more generally it approaches by flow degrees to its violent ftate. In this cafe it comes on with a fenfe of ftiffnefs in the back-part of the neck, which, gradually increafing, renders the motion of the head dif- ficult and painful. As the rigidity ofthe neck comes on and increafes, there is commonly at the fame time a fenfe cf uneafinefs felt about the root of the tongue; which by OF P H Y S IC. 101 degrees, becomes a difficulty of fwallowing, and at length an entire interruption of it. While the rigidity of the neck goes on increafing there arifes a pain, often violent, at the lower end ofthe fternum, and from thence fhoofinn in- to the back. When this pain arifes, all the mufcles of the neck, and particularly thofe of the back part of it, are im* mediately affeaed with fpafm, pulling the head ftrongly backwards. At the fame time, the mufcles that pull up the lower jaw, which upon the firft approaches of the dif- eafe were affeaed with fome fpaftic rigidity, are now gene- rally affeaed with more violent fpafm, and fet the teeth fo clofely together that they do not admit of the fmalleft opening. This is what has been named the Locked Jaw, and is often the principal part of the difeafe. When the difeafe has advanced thus far, the pain at the bottom of the fternum returns very frequently; and with it the fpafms of the hind neck and lower jaw are renewed with violence and much pain. As the difeafe thus proceeds, a greater number of mufcles come to be affeaed with fpafms. After thofe of the neck, thofe along the whole of the fpine become affea- ed, bending the trunk ofthe body ftrongly backwards; and this is what has been named the Opisthotonos. In the lower extremities, both the flexor and extenfor mufcles are commonly at the fame time affeaed, and keep the limbs rigidly extended. Though the extenfors of the head and back are ufually the moft ftrongly affeaed, yet the flexors, or thofe mufcles of the neck that pull the head forward, and the mufcles that fhould pull down the lower jaw, are often at the fame time ftrongly affeaed with fpafm. During the whole of the difeafe, the abdominal mufcles are violently affeaed with fpafm, fo that the belly is ftrong- ly retraaed, and feels hard as a piece of board. At length the flexors of the head and trunk become fo ftrongly affeaed as to balance the extenfors, and to keep the head and trunk ftraight, and rigidly extended, incapa- ble of being moved in any way; and it is to this ftate the term of Tetanus has been ftriaiy applied. At the fame time, the arms, little affeaed before, are now rigidly ex- tended; the whole of the mufcles belonging to them being affeaed with fpafms, except thofe that move the fingers, Vox., IT. N 102 PRACTICE which often to the laft retain fome mobility. The tongue alfo long retains its mobility ; but at length it alfo becomes affeaed with fpafms, which, attacking certain of its muf- cles only, often thrufts it violently out between the teeth. At the height of the difeafe, every organ of voluntary motion feems to be affeaed; and amongft the reft, the mufcles of the face. The forehead is drawn up into fur- rows, the eyes, fometimes diftorted, are commonly rigid, and immoveable in their fockets; the nofe is drawn up, and the cheeks are drawn backwards towards the ears, fo that the whole countenance expreffes the moft violent grin- ning. Under thefe univerfal fpafms, a violent convulfion commonly comes on, and puts an end to life. 1261.] Thefe fpafms are every where attended with moft violent pains. The utmoft violence of fpafm is how- ever, not conftant; but, after fubfifting for a minute or two, the mufcles admit of fome remiffion of their contrac- tion, although of no fuch relaxation as can allow the action of their antagonifts. This remiflion of contraaion gives alfo fome remiffion of pain; but neither is of long dura- tion. From time to time, the violent contraaions and pains are renewed fometimes every ten or fifteen minutes, and that often without any evident exciting caufe. But fuch exciting caufes frequently occur; for almoft every attempt to motion, as attempting a change of pofture, endeavoring to fwallow, and even to fpeak, fometimes gives occafion to a renewal of the fpafms over the whole body. 1262.J The attacks of this difeafe are feldom attended with any fever. When the fpafms are general and violent, the pulfe is contracted, hurried, and irregular; and the re- fpiration is affeaed in like manner: but, during the remif- fion, both the pulfe and refpiration ufually return to their natural ftate. The heat ofthe body is commonly not in- creafed ; frequently the face is pale, with a cold fweat up- on it; and very often the extremities are cold, with a cold fweat over the whole body. When, however, the fpafms are frequent and violent, the pulfe is fometimes more full and frequent than natural; the face is flufhed, and a warm fweat is forced out over the whole body. 1263.] Although fever be not a conftant attendant of 4his difeafe, efpecially when arifing from a lefion of nerves; yet, in thofe cafes proceeding from cold, a fever fometimes OF PHYSIC, 103 has fupcrvencd, and is faid to have been attended with in- flammatory fymptoms. Blood has been often drawn in this difeafe, but it never exhibits any inflammatory cruft ; and all accounts feem to agree, that the blood drawn feems to be of a loofer texture than ordinary, and that it does not coagulate in the ufual manner. 1264.] In this difeafe the head is feldom affiled with delirium or even confufion of thought, till the laft ftage of it; when, by the repeated fhocks of a violent diftemper, every funttion ofthe fyftem is greatly difordered. 1265.J It is no lefs extraordinary, that, in this violent difeafe, the natural funaions are not either immediately or confiderably affeaed. Vomitings fometimes appear early in the difeafe, but commonly they are not continued; and it is ufual enough for the appetite of hunger to remain through the whole courfe of the difeafe; and what food happens to be taken down, feems to be regularly enough digefted. The excretions are fometimes affeaed, but not always. The urine is fometimes fuppreffed, or is voided with difficulty and pain. The belly is coftive: but, as we have hardly any accounts excepting of thofe cafes in which opiates have been largely employed, it is uncertain whe- ther the coftivenefs has been the effea of the opiates or of the difeafe. In feveral inftances of this difeafe, a miliary eruption has appeared upon the ikin; but whether this be a fymptom ofthe difeafe, or the effea of a certain treat- ment of it, is undetermined. In the mean while, it has not been obferved to denote either fafety or danger, or to have any effett in changing the courfe of the diftemper. 1266.J This difeafe has generally proved fatal; and this indeed may be juftly fuppofed to be the confequence of its nature : but, as we know, that, till very lately, phyfi- cians were not well acquainted with a proper method of cure; and that fince a more proper method has been known and praaifed, many have recovered from this difeafe; it may be therefore concluded, that the fatal tendency of it is not fo unavoidable as has been imagined. In judging of the tendency of this difeafe, in particular cafes, we may remark, that, when arifing from lefions of the nerves, it is commonly more violent, and of more dif- ficult cure, than when proceeding from cold; that the dif- eafe which comes on fuddenly, and advances quickly to a 104 PRACTICE violent degree, is always more dangerous than that which is flower in its progrefs. Accordingly, the difeafe often proves fatal before the fourth day; and, when a patient has palfed this period, he may be fuppofed to be in greater fafety, and in general the difeafe is the fafer the longer it has continued. It is however, to be particularly obferved, that, even for many days after the fourth, the difeafe con- tinues to be dangerous; and, even after fome confiderable abatement of its force, it is ready to recur again with its former violence and danger. It never admits of any fud- den, or what is called critical folution; but always recedes by degrees only, and it is often very long before the whole of the fymptoms difappear. 1267.J From the hiftory of the difeafe now defcribed, it will-be evident, that there is no room for diftinguifhing the tetanus, opisthotonos, and trismus or locked jam, as different fpecies of this difeafe, fince they all arife from the fame caufes, and are almoft conftantly conjoined in the fame perfon. I have no doubt that the emprosthotonos be- longs alfo to the fame genus; and as the ancients have fre- quently mentioned it, we can have no doubt of its having occurred : But, at the fame time, it is certainly in thefe days a rare occurrence; and, as I have never feen it, nor find any hiftories in which this particular ftate ofthe fpafms is faid to have prevailed, I cannot mention the other cir- cumftances which particularly attend it, and may diftin- guifh it from the other varieties of tetanic complaints. 1268.] This difeafe has put on ftill a different form from any of tho,fe above mentioned. The fpafms have been fometimes confined to one fide ofthe body only, and wfiich bend it ftrongly to that fide. This is what has been named by Sauvages the Tetanus Lateralis, and by fome late wri- ters die Pleurosthotonos. This form of the difeafe has cer- tainly appeared very feldom; and, in any of the accounts given of it, I cannot find any circumftances that would lead me to confider it as any other than a variety of the fpecies already mentioned, or to take further notice of it here. 1269.] The pathology of this difeafe I cannot in any meafure attempt; as the ftruaure of moving fibres, the ftate of them under different degrees of contraaion, and particularly the ftate of the fenforium, as varioufly deter- mining the motion of the nervous power; are all matters O F P H Y S I C. 105 very imperfeaiy, or not at all, known to me. In fuch a fituation, therefore, the endeavouring to give any rules of praaice, upon a fcientific plan, appears to me vain and fruitlefs ; and towards dire.aing the cure of this difeafe, we mult be fatisfied with having learned fomcthing ufeful from analogy, confirmed by experience. 1270.] When the difeafe is known to arife from the le- fion of a nerve in any part of the body, the firft, and as I Judge, the moft important ftep to be taken towards the cure, is, by every poffible means, to cut off that part from all communication with the fenforium, either by cutting thro' the nerves in their courfe, or perhaps by deftroying, to a certain length, their affeaed part or extremity. 1271.] When the cure ofthe difeafe is to be attempted by medicine, experience has taught us that opium has of- ten proved an effeaual remedy; but that, to render it fuch, it muft be given in much larger quantities than have been employed in any other cafe; and in thefe larger quantities, it may, in this difeafe, be given more fafely than the body has been known to bear in any other condition. The prac- tice has been, to give the opium either in a folid or liquid form, not in any very large dofe at once, but in moderate dofes, frequently repeated, at the interval of one, two, three, or more hours, as the violence of the fymptoms feem to require.* Even when large quantities have been given in this way, it appears that the opium does not ope- rate here in the fame manner as in moft other cafes; for, * Though the exhibition of opium in Tetanus has been the moft. univerfal praftice, it muft neverthelefs be acknowledged, that, in many, if not in moft cafes, it has been ineffectual. The difeafe, indeed, is in general fatal; but, as in moft of the cafes that terminated happily, opium has been given, as the Author defcrihes, either in large dofes, or frequently repeated fmall dofes,. we muft neceffarily conclude that the praftice ought to be followed. I have feen only one cafe of Tetanus; it proceeded from a wound which a carpenter received in the wrift of his left arm with a faw. The inflammation was vio- lent: The ftiffnefs of the neck at firft appeared on the third day, when the inflammation began to abate after bleeding, and the application of emollient poultices: The pulfe was weak and fmall; thirty drops of laudanum were given ; the fymptoms increafed ; and, on the day-following, the jaw became fixed. Thirty drops of laudanum were repeated ; and the fymptoms abating within two hours after its exhibition, indicated a repetition of the dofe. which, from its good effe&s, was a fourth time repeated that fame day. The wound fuppurated ; and the day following, with two dofes of forty drops of laudanum, the fymptoms of Tetanus wholly difappeared, but hf the patient in a moft debilitated ftate. A coftivenefs fupervened, that was removed with the ufe of manna and Glauber's falts occafionally: The patient was nourifhed with rich broths and wine; but he did not recover hir> former ftrength til! after Jix weeks, although the wound healed in half that tur.e. 106 PRACTICE though it procure fome remiffion ofthe fpafms and pains, it hardly induces any fleep, or occafions that ftupor, intox- ication, or delirium, which it often does in other circum- ftances, when much fmaller quantities only have been given. It is therefore very properly obferved, that, in tetanic af- feaions, as the opium fhows none of thofe effeas by which it may endanger life, there is little or no reafon for being fparing in the exhibition of it; and it may be given, proba- bly fhould be given, as largely and as fait as the fymptoms of the difeafe may feem to demand. It is particularly to be obferved,that though thefirft ex- hibition of the opium may have produced fome remiflion of the fymptoms, yet the effeas of opium do not long con- tinue in the fyftem ; and this difeafe being for fome time ready to recur, it is commonly very neceffary, by the time that the effeas ofthe opium given may be fuppofed to be wearing off, and efpecially upon the leaft appearance of the return of the fpafms, to repeat the exhibition of the opium in the fame quantities as before. This praaice is to be continued while the difeafe continues to fhow any difpofition to return ; and it is only after the difeafe has already fubfifted for fome time, and when confiderable and long-continued remiffions have taken place, that the dofes ofthe opium may be diminifhed, and the intervals of ex- hibiting them be more confiderable. 1272. J The adminiftering of opium in this manner, has in many cafes been fuccefsful; and probably would have been equally fo in many others, if the opium had not been toofparingly employed, either from the timidity of praai- tioners, or from its exhibition being prevented by that in- terruption of deglutition which fo often attends this difeafe. The latter circumftance direas, that the medicine fliould be immediately and largely employed upon the firft ap- proach ofthe difeafe, before the deglutition becomes diffi- cult; or that, if this opportunity be loft, the medicine, in fufficient quantity, and with due frequency, fhould be thrown into the body by glyfters; which, however, does not feem to have been hitherto often praaifed. 1273.] It is highly probable, that, in this difeafe, the in- teftines are affeaed with the fpafm that prevails fo much in other parts ofthe fyftem; and therefore that coftivenefs O F P H Y S I C. 1CKT occurs here as a fymptom of the difeafe.* It is probably alfo increafed by the opium, which is here fo largely em. ployed; and, from whichever of thefe caufes it arifes, it cer- tainly muft be held to aggravate the difeafe, and that a re- laxation of the inteftinal canal will contribute to a relaxati- on of the fpafms elfewhere. This confideration directs tire frequent exhibition of laxitives while the power of deglu- tition remains, or the frequent exhibition of glyfters when it does not; and the good effects of both have been fre- quently obferved. 1274.] It has been with fome probability fuppofed, that the operation of opium in this difeafe, may be much affift- ed by joining with it fome other of the moft powerful an- tifpafmodics. The moft promifing are mufk and cam- phire; and fome praaitioners have been of opinion, that the former has proved very ufeful in tetanic complaints. But, whether it be from its not having been employed of a genuine kind, or in fufficient quantity, the great advantage and propriety of its ufe are not yet clearly afcertained. It appears to me probable, that analogous to what happens with refpea to opium, both mufk and cam phi re might be employed in this difeafe, in much larger quantities than they commonly have been in other cafes. 1275.J Warm bathing has been commonly employed as a remedy in this difeafe, and often with advantage; but, fo far as I know, it has not alone proved a cure; and, in fome cafes, whether it be from the motion of the body here required, exciting the fpafms, or from the fear of the bath, which fome perfons were feized with, I cannot determine; but it is allowed, that the warm bath hath in fome cafes done harm, and even occafioned death. Partial fomenta- tions have been much commended, and, I believe, upon good grounds: And I have no doubt but that fomentations ofthe feet and legs, as we now ufually apply them in fevers, might, without much ftirring of the patient, be very affidu- Qufly employed with advantage. 1276.J Unauous applications were very frequently em- ployed in this difeafe by the ancients: and fome modern praaitioners have confidered them as very ufeful. Their effeas, however, have not appeared to be confiderable; and, as a weak auxiliary only, attended with fome incon- * This fymptom occurred in the cafe mentioned in the preceding note. 108 PRACTICE venience, they have been very much ncgleaed by the Bii- tifh praaitioners. 1277.] Bleeding has been formerly employed in this difeafe; but of late it has been found prejudicial, except- ing in a few cafes, where, in plethoric habits, a fever has fupervened. In general, the ftate of men's bodies in warm climates is unfavorable to blood-letting: and, if we mav form indications from the ftate of the blood drawn out of the veins, the ftate of this in tetanic difeafes would forbid bleeding in them. 1278.J Bliftering alfo has been formerly employed in this difeafe; but feveral praaitioners affert, that blifters are conftantly hurtful, and they arc now generally omitted. 1279.] Thefe are the praaices that hitherto have been generally employed; but of late we are informed by feve- ral Weft India praaitioners, that in many inftances they have employed mercury with great advantage. We are told, that it muft be employed early in the difeafe ; that it is moft conveniently adminiftered by unaion, and fhould be applied in that way in large quantities, fo that the body may be foon filled with it, and a falivation raifed, which is to be continued till the fymptoms yield. Whether this method alone be generally fufficient for the cure of the dif- eafe, or if it may be affifted by the ufe of opium, and re- quire this in a certain meafure to be joined with it, I have not yet certainly learned. 1280.] I have b6en further informed, that the tetanus, in all its different degrees, has been cured by giving inter- nally the Piffelacum Barbadenfe, or, as it is vulgarly cal- led, the Barbadoes Tar. I think it proper to take notice of this here, although I am not exaaiy informed what quantities of this medicine are to be given, or in what cir- cumftances of the difeafe it is molt properly to be era- ployed. 1281.] In the former edition of this work, among the remedies of tetanus I did not mention the ufe of cold bath- ing; becaufe, though I heard of this, I was not informed of fuch frequent employment of it as might confirm my opinion of its general efficacy; nor was I fufficiently in- formed of the ordinary and proper adminiftration of it. But now, from the information of many judicious praai- tioners who have frequently employed it, I can fay, that it OF PHYSIC. 109 Is a remedy which in numerous trials has been found to be of great fervice in this difeafe; and that, while the ufe of the ambiguous remedy of warm bathing is entirely laid a- fide, the ufe of cold bathing is over the whole of the Weft Indies Commonly employed. The adminiftration of it is fometimes by bathing the perfon in the fea, or more fre- quently by throwing cold water from a bafon or bucket upon the patient's body, and over the whole of it: When this is done, the body is carefully wiped dry, wrapped in blankets, and laid abed, and at the fame time a large dofe of an opiate is given. By thefe means a confiderable re- miffion of the fymptoms is obtained; but this remiffion, at firft, does not commonly remain long, but returning again in a few hours, the repetition both of the bathing and the opiate becomes neceffary. By thefe repetitions, however, longer intervals of eafe are obtained, and at length the dif- eafe is entirely cured; and this even happens fometimes very quickly. I have only to add, that it does not appear to me, from any accounts that I have yet had, that the cold bathing has been fo frequently employed, or has been found fo commonly fuccefsful in the cafes of tetanus in confequence of wounds, as in thofe from the application of cold. 1282. J Before concluding this chapter, it is proper for me to take fome notice of that peculiar cafe of the tetanus, or trifmus, which attacks certain infants foon after their birth, and has been properly enough named the Trifmus Nufcentium. From the fubjects it affeas, it feems to be a peculiar difeafe: for thefe are infants not above two weeks, and commonly before they are nine days, old; in- fomuch that, in countries where the difeafe is frequent, if children pafs the period now mentioned, they are confider- ed as fecure againft its attacks. The fymptom of it chiefly taken notice of, is the trifmus, or locked jaw, which is by the vulgar improperly named the Falling of the Jaw. But this is not the only fymptom, as, for the moft part, it has all the fame fymptoms as the Opifthotonos and Tetanus ^riaiy fo called, and which occur in the other varieties of the tetanic complaints above defcribed. Like the other varieties of tetanus, this is moft frequent in warm climates, but it is not, like thofe arifing from the application of cold, Vol. II. O 110 PRACTICE entirely confined to fuch warm climates, as inftances of it . have occurred in moft of the northern countries of Europe. ; In thefe latter it feems to be more frequent in certain dif- trias than in others; but in what manner limited, I cannot determine. It feems to be more frequent in Switzerland than in France. I am informed of its frequently occurr- ing in the Highlands of Scotland; but I have never met with any inftance of it in the low country. The particular caufes of it are not well knownr and various conjeaures have been offered; but none of them are fatisfying. It is a difeafe that has been almoft conftantly fatal; and this, 1 alfo, commonly in the courfe of a few days. The women 1 are fo much perfuaded of its inevitable fatality, that they feldom or never call for the affiftance of our art. This has by cutting it out, or by de- ftroying it by the application of anaaual or potential cau- tery. idly, When the part cannot be properly deftroyed, that we fhould endeavour to correa the morbid affection in it by bliftering, or by eftablifhing an iffue upon the part. %dly, When thefe meafures cannot be executed, or do not fucceed, if the difeafe feems to proceed from the ex- tremity of a particular nerve which we can eafily come at in its courfe, it will be proper to cut through that nerve, as before propofed on the fubjea of tetanus. 4_thly, When it cannot be perceived that the aura arifes from any precife place or point, fo as to direa to theabove- mentioned operations ; but, at the fame time, we can per- ceive its progrefs along the limb ; it frequently happens that the epilepfy can be prevented by a ligature applied upon the limb, above the part from which the aura arifes; and this is always proper to be done, both becaufe the pre- venting a fit breaks the habit of the difeafe, and becaufe the frequent compreffion renders the nerves lefs fit to pro- pagate the aura. 1320.] The cure of idiopathic epilepfy, as I have faid above, is to be direaed by our knowledge of the remote caufes. There are therefore two general indications to be formed. The firft is, to avoid the occafional caufes; and the fecond is, to remove or correa the predifponent. This method, however, is not always purely palliative; as in many cafes the predifponent may be confidered as the only proximate caufe, fo our fecond indication may be of- ten confidered as properly curative. 1321.J From the enumeration given above, it will be manifeft, that for the moft part the occafional caufe:;, fo ii:: PRACTICE far as they are in our power, need only to be known, in order to be avoided; and the means of doing this will be fufficiently obvious. I fhall here, therefore, offer only a few remarks. 1322. J One ofthe moft frequent ofthe occafional caufes is that of over diftention (1314.) which, fo far as it depends upon a plethoric ftate of the fyftem, I fhall fay hereafter how it is to be avoided. But as, not only in the plethoric, but in every moveable conftitution, occafional turgefcence is a frequent means of exciting epilepfy, the avoiding there- fore of fuch turgefcence is what ought to be moft conftant- ly the objea of attention to perfons liable to epilepfy. 1323.J Another of the moft frequent exciting caufes of this difeafe are, all ftrong impreffions fuddenly made upon the fenfes; for as fuch impreffions, in moveable constitu- tions, break in upon the ufual force, velocity, and order of : the motions of the nervous fyftem, they thereby readily produce epilepfy. Such impreffions therefore, and efpe- cially thofe which are fuited to excite any emotion or paf- fion of the mind, are to be moft carefully guarded againft by perfons liable to epilepfy. 1324.J In many cafes of epilepfy, where the predifpo- nent caufe cannot be correaed or removed, the recurrence of the difeafe can only be prevented, by the ftritlefl atten- tion to avoid the occafional; and as the difeafe is often con- firmed by repetition and habit, fo the avoiding the frequent recurrence of it is of the utmoft importance towards its cure. Thefe are the few remarks I have to offer with refpea to the occafional caufes; and muft now obferve, that, for the moft part, the complete, or, as it is called, the Radical Cure, is only to be obtained by removing or correaing the predifponent caufe. 1325.J I have faid above, that the predifponent caufe of epilepfy is a certain mobility ofthe fenforium; and that this depends upon a plethoric ftate of the fyftem, or upon a certain ftate of the debility in it. 1326.] How the plethoric ftate of the fyftem is to be correaed, I have treated of fully above in (781. et seq.) and I need not repeat it here. It will be enough to fay, that it is chiefly to be done by a proper management of exercife and diet; and, with refpea to the latter, it is par- ticularly to be obferved here, that an abftemious courfe has OF PHYSIC. 123 been frequently found to be the moft certain means of curing epilepfy. 1327.] Confidering the nature ofthe matter poured out by iffues, thefe may be fuppofed to be a conftant means of obviating the pf ihoric ftate of the fyftem ; and it is, per- haps, therefore, that they have been fo often found ufeful in epilepfy. Poffibly, alfo, as an open iffce may be a means ofdetermining occafional turgefcences to fuch places, and therefore of diverting them in fome meafure from their aaion upon the brain; fo alfo, in this manner, iffues may be ufeful in epilepfy. 1328.] It might be fuppofed that blood-letting would be the moft effeaual means of correaing the plethoric ftate of the fyftem; and fuch it certainly proves when the ple- thoric ftate has become confiderable, and immediately threatens morbid effeas. It is therefore, in fuch circum- ftances, proper and neceffary: But as we have faid above, that blood-letting is not the proper means of obviating a recurrence of the plethoric ftate, and, on the contrary, is often the means of favoring it; fo it is not a remedy advifa- ble in every circumftance of epilepfy. There is, however, a cafe of epilepfy in which there is a periodical or occa- fional recurrence of the fulnefs and turgefcence of the fan- guiferous fyftem, giving occafion to a recurrence of the difeafe. In fuch cafes, when the means of preventing ple- thora have been neglected, or may have proved ineffeaual, it is abfolutely neceffary for the praaitioner to watch the returns of thefe turgefcences, and to obviate their effeas by the only certain means of doing it, that is, by a large blood-letting. 13 29. J The fecond caufe of mobility which we have af- figned, is a ftate of debility. If this is owing, as it frequent- ly is, to original conformation, it is perhaps not poffible to cure it; but when it has been brought on in the courfe of life, it poffibly may admit of being mended; and, in either cafe, much may be done to obviate and prevent its effeas. 1330.] The means of correaing debility, fo far as it can be done, are, The perfon's being much in cool air; the frequent ufe of cold bathing; the ufe of exercife, adapted to the ftrength and habits of the perfon; and, perhaps, the •ufe of aftringent and tonic medicines. Thefe remedies are fuited to ftrengthen the inherent 124 PRACTICE power of the folids or moving fibres: but as the ftrength of thefe depends alfo upon their tenfion, fo when debility has proceeded from inanition, the ftrength may be reftor- ed, by reftoring the fulnefs and tenfion of the veffels by a nourifhing diet; and we have had inftances of the proprie- ty and fuccefs of fuch a praaice. 1331.] The means of obviating the effeas of debility, and ofthe mobility depending upon it, are the ufe of tonic and antifpafmodic remedies. The tonics are, Fear, or fome degree of terror ; aftrin- gents ; certain vegetable and metallic tonics; and cold- bathing. 1332.J That fear, or fome degree of terror, may be of ufe in preventing epilepfy, we have a remarkable proof in Boerhaave's cure of the epilepfy, which happened in the Orphan-houfe at Haerlem. See Kauu Boerhaave's trea- tife, intitled Impetum Faciens, § 406. And we have met with feveral other inftances ofthe fame. As the operation of horror is in many refpeas analogous to that of terror, feveral feemingly fuperltitious remedies have been employed for the cure of epilepfy ; and, if they have ever been fuccefsful, I think it muft be imputed to the horror they had infpired.* 1333. J Ofthe aftringent medicines ufed for the cure of epilepfy, the moft celebrated is the viscus quercinus, which, when given in large quantities, may poffibly be ufeful; but I believe it was more efpecially fo in ancient times, when it was an objea of fuperftition. In the few inftan- ces in which I have feen it employed it did not prove of any effea.f 1334-J Among the vegetable tonics, the bitters are to be reckoned; and it is by this quality that I fuppofe the o- range-tree leaves to have been ufeful : but they are not always fo. 1335-J The vegetable tonic, which from its ufe in ana- logous cafes is the moft promifing, is the Peruvian bark; * Drinking a draught of the blood of a gladiator juft killed; drinking a draught of water with a toad at the bottom of the jug; eating a piece of hu- man liver, or the marrow ofthe bones ofthe leg of a malefactor; powder of the human fkisll; or the mofs that grows on it; with a variety of fuch abomi- nable remedies, were formerly in great repute, and indeed fome of them are ftill retained in feveral foreign Pharmacopoeias. — t The dofe of it was from half a drachm to a drachm in powder, or about an ownce in i.ifuhon. OF PHYSIC. 133 this, upon occafion, has been ufeful, but has alfo often fail- ed. It is efpecially adapted to thofe epilepfies which recur afcertain periods, and which are at the fame time without the recurrence of any plethoric ftate, or turgefcence of the blood; and in fuch periodical cafes, if the bark is employed fome time before the expeaed recurrence, it may be ufeful; but it muft be given in large quantity, and as near to the time of the expected return as poffible. 1336.] The metallic tonics feem to be more powerful than the vegetable, and a great variety of the former have been employed. Even arfenic has been employedin the cure of epilepfy; and its ufe in intermittent fevers gives an analogy in its favour. Preparations of tin have been formerly recommended in the cure of epilepfy, and in the cure of the analogous difeafe of hyfteria ; and feveral confiderations render the virtues of tin, with refpea to thefe difeafes, probable : but I have had no experience of its ufe in fuch cafes. A much fafer metallic tonic is to be found in the prepa- rations of iron ; and we have feen fome of them employ- ed in the cure of epilepfy, but have never found them to be effeaual. This, however, I think, may be imputed to their not having been always employed in the circumftan- ces ofthe difeafe, and in the quantities of the medicine, that were proper and neceffary.* 1337.] Of the metallic tonics, the moft celebrated and the moft frequently employed is copper, under various preparation. What preparation of it may be the moft ef- feaual, I dare not determine ; but of late the cuprum am- moniacum has been frequently found fuccefsful.t 1338.] Lately the flowers of zinc have been recommend- ed by a great authority as ufeful in all convulfive difor- ders ; but in cafes of epilepfy, I have not hitherto found that medicine ufeful. J * The method cf ufing iron was defcribed in a note on article 576. t This was a favorite remedy of the Author's. He firft introduced it into practice in this country, and the preparation of it was inferted in the Edin- burgh Pharmacopoeia. It is employed by beginning with fmall dofes of half a grain, and increafing them gradually to as much as the ftomach will bear. It is, however, like all preparations of copper, a very dangerous medicine, and ought to be ufed with caution. f The great authority by which the flowers of zinc were recommended was Gaubius. It is as dangerous a medicine as the cuprum ammoaiacum, and muft be ufed with the fame caution. Vol. II. Q 126 PRACTICE 1339.] There have been of late fome inftances of the cure of epilepfy by the accidental ufe of mercury ; and if the late accounts ofthe cure of tetanus by this remedy are confirmed, it will allow us to think that the fame may be adapted alfo to the cure of certain cafes of epilepfy. 1340.] With refpea to the employment of any ofthe above mentioned tonics in this difeafe,it muft be obferved, that in all cafes where the difeafe depends upon a conftant or occafional plethoric ftate ofthe fyftem thefe remedies are likely to be ineffeaual; and if fufficient evacuations are not made at the fame time, thefe medicines are likely to be very hurtful. 1341.] The other fet of medicines which we have men- tioned as fuited to obviate the effeas of the two great mo- bility of the fyftem, are the medicines named antispasmo- dics. Of thefe there is a long; lift in the writers on the Materia Medica, and by thefe authors recommended for the cure of epilepfy. I'he greater part, however, of thofe taken from the vegetable kingdom, are manifeftly inert and infignificant.* Eventhe root of the wild valerian hard- ly fupports its credit. 1342.J Certain fubftances taken from the animal king- dom feem to be much more powerful: and of thefe the chief, and feemingly the moft powerful, is mufk ; which employed in its genuine ftate, and in due quantity, has of- ten been an effeaual remedy.t It is probable alfo, that the oleum arrimale, as it has been * This is certainly true ; but it muft be acknowledged that fome of them are manifeftly active and ufeful, as the afafcetida, fagapenum, and other fetid gums. The pilulx gummofae of the Pharmacopoeias are good formulae for thefe naufeous medicines ; and their being reputed inefficacious and infigni- ficant feems to have arifen from their not having been given in fufficient large dofes. They may be given with fafety to the quantity of two drachms in a day, in repeated dofes of twenty or thirty grains each ; and, if they ftiould happen to purge, this inconvenience may be prevented, by adding a quarter or half a grain of opium to each dofe of the pills, or taking tea drops of lau- danum after each dofe, as occafion may require. f Mufk is more eSTeclual when given in fubftance than in any preparation that has been attempted; it is given in dofes of from ten to thirty grains, and frequently repeated. It may be made into a bolus, as in the following formula : Be. Mosch. gr. xv. Tere in mortar, marmor. cum Sacch. alb. t^i.; et adde Confe£t. cardiac. 3ss. M. f. Bolus. This bolus may be repeated three or four times a-day, OF PHYSIC. 127 named, when in its pureft ftate, and exhibited at a proper time, may be an effeaual remedy.* 1343.] In many difeafes, the moft powerful antifpafmo- dic is certainly opium ; but the propriety of its ufe in epi- lepfy has been difputed among phyficians. When the dif- eafe depends upon a plethoric ftate in which bleeding may be neceffary, the employment of opium is likely to be ve- ry hurtful : but, when there is no plethoric or inflammato- ry ftate prefent, and the difeafe feems to depend upon irri-" tation,or upon increafed irritability, opium is likely to prove the moft certain runedy.t Whatever effeas in this and other convulifve diforders have been attributed to the hy- ofcyamus, muft probably be attributed to its poffefling a narcotic power fimilar to that of opium. 1344.] With refpea to the ufe of antifpafmodics, it is to be obferved, that they are always moft ufeful, and perhaps only ufeful, when employed ata time when epileptic fits are frequently recurring, or near to the times ofthe accef- fion of fits which recur after confiderable intervals. 1345«] Oi the fubjea of the cure of epilepfy, I have on- ly to add, that as the difeafe in many cafes is continued by the power of habit only, and that in all cafes habit has a great fhare in increafing mobility, and therefore in continu- ing this difeafe; fo the breaking in upon fuch habit, and changing the whole habits ofthe fyftem, it is likely to be a powerful remedy in epilepfy. Accordingly, a confidera- ole change of climate, diet, and other circumftances in the manner of life, has often proved a cure of this difeafe.^ 1346.] After treating of epilepfy, I might here treat of * The dofe of this oil is from twenty to thirty drops; it is, however, fel- dom ufed. j In thofe cafes, in which fome peculiar fymptoms indicate the approach of the rit, opium taken in a large dofe has fometimes prevented it altogether; but moft commonly, however, fuch a dofe greatly Ieffens its violence. Two grains of opium in fubftance, or fixty or feventy drops of laudanum, are large xlofes. J: After all that has been faid on this difeafe, we muft acknowledge that we know but little of its true nature, and, confequently, no certain method of cure can be given. It has baffled the fkill cf phyficians from the earliett ages of phyfie, and ftill remains to be one of thofe many difeafes which we cannot certainly cure. Some fpecies of it, indeed, are certainly curable ; but thefe are few, and fuch only as are fymptomatic, or arife from peculiar mechanical irritations. Experience has moreover fhown us, that the difeafe often exifts without any apparent irritation, and without any caufe obfervable on diffec- tion : Much room is therefore left for future inveftigations 011 this dark fub- jeil; and we muft at prefent content ourfelves with the hopes that time will unfold what human ingenuity has not yet been capable of eifefling. «t 123 PRACTICE particular convulfions, which arc to be diftinguifhed froirV epilepfy by their being more partial : that is, affeaing cer- tain parts ofthe body only, and by their not being attend- ed with a lofs of fenfe, nor ending in fuch comatofe ftate as epilepfy always does. 1347.] Of fuch convulfive affeaions many different in- ftances have been obferved and recorded by phyficians. But many of thefe have been manifeftly fympathic affetti- *ons, to be cured only by curing the primary difeafe upon which they depend, and therefore not to be treated of here: Or, though they are fuch as cannot be referred to another difeafe, as many of them however have not any fpecific charaaer with which they occur in different perfons, I muft therefore leave them to be treated upon the general principles I have laid down with refpea to epilepfy, or fhall lay down with refpea to the.following convulfive dif- order; which, as having very conftantly in different per- fons a peculiar charaaer, I think neceffary to treat of more particularly. t——^»———.» CHAP. III. £Df tfje Cfjorca or Dance of %t. Ottus* 1348.] X HIS difeafe affeas both fexes, and almoft on- ly young perfons. It generally happens from the age of ten to that of fourteen years.* It comes on always before the age of puberty, and rarely continues beyond that period. 1349.] It is chiefly marked by convulfive motions fome- what varied in different perfons, but nearly of one kind in all; affbaing the leg and arm on the fame fide, and gener- ally on one fide only. 1350.] Thefe convulfive motions commonly firft affeQ: the leg and foot. Though the limb be at reft, the foot is often agitated by convulfive motions, turning it alternately outwards and inwards. When walking is attempted, the affeaed leg is feldom lifted as ufual in walking, but is drag- ged along as if the whole limb were paralytic; and, when it is attempted to be lifted, this motion is unfteadily per- * I have feen it in a robuft man of forty-two. This patient, after various ineffectual remedies had been ufed,,- was cured by ftrong electrical fhocks di- re Ac d through the v/hole body. 0 F P H Y S I C. 129 formed, the limb becoming agitated by irregular convuU five motions. 1351.] The arm of the fame fide is generally affeaed at the lame time; and, even when no voluntary "motion is at- tempted, the arm is frequently agitated with various con- rulfive motions. But efpecially when voluntary motions are attempted, thefe are not properly executed, but are varioufly hurried or interrupted by convulfive motions in a direaion contrary to that intended. The moft common inftance of this is in the perfon's attempting to carry a cup of liquor to his mouth, when it is only after repeated efforts, interrupted by frequent convulfive retraaions and devia- tions, that the cup can be carried to the mouth. 1352.J It appears to me, that the will often yields to thefe convulfive motions, as to a propcnfity, and thereby they are often increafed, while the perfon affeaed feems to be pleafed with increafing the furprife and amufement which his motions occafion in the byftanders. 1353.] In this difeafe the mind is often affeaed with fome degree of fatuity; and often fhows the fame varied, defultory, and caufelefs emotions which occur in hyfteria. 1354. J Thefe are the moft common circumftances of this difeafe ; but at times, and in different perfons, it is varied by fome difference in the convulfive motions, particularly by thefe affeaing the head and trunk of the body. • As in this difeafe there feem to be propenfities to motion, fo va- rious fits of leaping and running occur in the perfons affea- ed ; and there have been inftances of this difeafe, confift- ing of fuch convulfive motions, appearing as an epidemic in a certain corner ofthe country. In fuch inftances, per- fons of different ages are affeaed, and may feem to make an exception to the general rule above laid down; but ftill the perfons are, for the moft part, the young of both fexes, and ofthe more manifeftly movable conftitutions. 1355. J The method of curing this difeafe has been va- rioufly propofed. Dr. Sydenham propofed to cure it by alternate bleeding and purging. In fome plethoric habits I have found fome bleeding ufeful; but.in many cafes I have found repeated evacuations, efpecially by bleeding, very hurtful. In many cafes, I have found the difeafe, in fpite of re- medies of all kinds, continue for many months; but I have \:,o PRACTICE alfo found it often readily yield to tonic remedies, fucH as the Peruvian bark, and chalybeates. The late Dr. De Haen found feveral perfons laboring under this difeafe cured by the application of elearicity. Sect. II. Ofthe Spasmodic Affections ofthe Vital Functions. CHAP. IV.* ©f tbe palpitation cf t&c $>eart. 1356.] X HE motion thus named is a contraaion or fyf- tole of the heart, that is performed with more rapidity, and generally alfo with more force than ufual and when at the fame time the heart ftrikes with more than ufual violence againft the infide of the ribs, producing often a confidera- ble found. 1357.] This motion, or palpitation, is occafioned by a great variety of caufes, which have been.recited with great pains by Mr. Senac and others ; whom, however, I can- not follow in all the particulars with fufficient difcernment, and therefore fliall here only attempt to refer all the feve- ral cafes of this difeafe to a few general heads. 1358.] The firft is of thofe arifing from the application of the ufual ftimulus to the heart's contraaion; that is, the influx of the venous blood into its cavities, being made with more velocity, and therefore, in the fame time, in greater quantity than ufual. It feems to be in this man- ner that violent exercife occafions palpitation. 1359. J A fecond head ofthe cafes of palpitation, is of thofe arifing from any refiftance given to the free and en- tire evacuation ofthe ventricles ofthe heart. Thus a liga- ture made upon the aorta occafions palpitations of the moft violent kind. Similar refiftances, either in the aorta or pulmonary artery, may be readily imagined ; and fuch has been often found in the dead bodies of perfons who, during life, had been much affeaed with palpitations. To this head are to be referred all thofe cafes of palpi- * Though I have thought it proper to divide this book into fecYions, I think it necefTary, for the convenience of references, to number the chapters from the beginning. Author. 0 F P H V S I C. IS1 taiion arifing from caufes producing an accumulation of blood in the great veffels near to the heart. 1360.] A third head ofthe cafes of palpitation, is of thofe m arifing from a more violent and rapid influx ofthe nervous power into the mufcular fibres of the heart. It is in this manner that I fuppofe various caufes acting in the brain, and particularly certain emotions of the mind occafion palpitation. 1361.] A fourth head of the cafes of palpitation, is of thofe arifing from caufes producing a weaknefs in the ac- tion ofthe heart, by diminifhing l he energy of the brain with refpea to it. That fuch caufes operate in producing palpitation, I prefume from hence, that all the feveral cau- fes mentioned above (1177. et seq.), as in this manner pro- ducing fyncope, do often produce palpitation. It is on this ground that thefe two difeafes are affeaions frequently occurring in the fame perfon, as the fame caufes may oc- cafion the one or the other, according to the force of the caufe and mobility ofthe perfon acted upon. It feems to be a law of the human economy, that a degree of debility occurring in any funaion, often produces a more vigour- ous exertion of the fame, or at leaft an effort towards it., and that commonly in a convulfive manner. I apprehend it to be the convulfive aaion, frequently ending in fome degree of a fpafm, that gives occafion to the intermittent pulfe fo frequently accompanying palpitation. 1362.] A fifth head of the cafes of palpitation may per- haps be of thofe arifing from a peculiar irritability or mo- bility ofthe heart. This, indeed, may be confidered as a predifponent caufe only, giving occafion to the aaion of the greater part of the caufes recited above. But it is pro- per to obferve, that this predifpofition is often the chief part of the remote caufe; infomuch that many of the caufes producing palpitation would not have this effea but in per- fons peculiarly predifpofed. This head, therefore, of the cafes of palpitation, often requires to be diftinguifhed from all the reft. r 1363.] After thus marking the feveral cafes and caufes of palpitation, I think it neceffary, with a view to the cure of this difeafe, to obferve, that the feveral caufes of it may be again reduced to two heads. The firft is, of thofe con- fifting in, or depending upon, certain organic affeaions of 132 PRACTICE the heart itfelf, or of the great veffels immediately connea- ed with it. The fecond is, of thofe confifting in, or de-* pending upon, certain affeaions fublifting and acini!; in- other parts of the body, and acting either by the force of the caufe, or in confequence of the mobility of the hcait, 1364.J With refpea to the cafes depending upon the firft fet of caufes, I muft repeat-here what I faid with ref- pea to the like cafes of fyncope, that I do not know any .means of curing them. They, indeed, admit of fome pal- liation, first, by avoiding every circumftance1 that may hurry the circulation ofthe blood; and, second, by every means of avoiding a plethoric fiate of the fyftami, or any occafional turgefcence of the blood. In mahy of thefe cafes, blood-letting may give a temporary relief: But in fo far as debifity and mobility are concerned, in fuch cafes this remedy is likely to dp h-rm. 1365.J With refpect to the cafes depending upon the other fet of caufes, they may be various, and require very different meafures: But I can here fay in general, that thefe cafes may be confidered as of two kinds; one de- pending upon primary affeaions in other parts of the body, and aaing by the force ofthe particular caufes; and ano- ther depending upon a ftate of mobility in the heart itfelf. In the firft of thefe, it is obvious, that the cure of palpita- tion muft be obtained by curing the primary affeaion*; which is not to be treated of here. In the fecond, the cure muft be (obtained, partly by diligently avoiding the occa- fional caufes, partly and chiefly by correaing the mobility of the fyftem, and of the heart in particular; for doing which we have treated ofthe proper means elfewhere. CHAP. V. ©f £>£0pnoea, or Difficult 15reatfmtg, 1366.] X HE exercife of refpiration, and the organs*of it, have fo conftant and confiderable a conneaion with almoft the whole of the other funaions and parts ofthe human body, that upon almoft every occafion of difeafe, refpiration muft be effeaed. Accordingly, fome difficul- ty and diforder in this funaion, are in faa fymptoms very generally accompanying difeafe. - ■O F P H Y S IC. 133 1367.] Upon this account, the fymptom of difficult breathing deferves a chief place and an ample confiderati- on in the general fyftem of Pathology; but what fhare of confideration it ought to have in a treatife of Praaice, I find it difficult to determine. 1368.] On this fubjea, it is, in the firft place, neceffary to diftinguifh between the fymptomatic and idiopathic af- feaions ; that is, between thofe difficulties of breathing which are fymptoms only of a more general affeaion, or of a difeafe fubfifting primarily in other parts than the organs of refpiration, and that difficulty of breathing which depends upon a primary affeaion ofthe lungs themfelves. The various cafes of fymptomatic dyfpnoea I have taken pains to enumerate in my Methodical Nofology, and it will be obvious they are fuch as cannot be taken notice of here. 1369.] In my Nofology I have alfo taken pains to point out and enumerate the proper, or at leaft the greater part ofthe proper, idiopathic cafes ofthe dyfpncea: but from that enumeration it will, I think, readily appear, that few, and indeed hardly any, of thefe cafes, will admit or require much of our notice in this place. 1370.] The Dyfpncea Sicca,* species 2d, the Dyfpncea Acreage sp. %d, the Dyfpnoea Terrea,\ sp. 4th, and Dyfp- ncea Thoracica,\\ sp. jth* are fome of them with difficulty known, and are all of them difeafes which in my opinion do not admit of cure. All, therefore, that can be faid con- cerning them here is, that they may admit of fome pallia- tion; and this, I think, is to be obtain chiefly by avoiding a plethoric ftate of the lungs. § and every circumftance that may hurry refpiration. 1371.] Of the Dyfpncea Extrinseca,^ sp. %th, I can fay no more, but that thefe external caufes marked in the Nofology, and perhaps fome others that might have like effeas, are to be carefully avoided; or, when they have been applied, and their effeas have taken place, the difeafe is to be palliated by the means mentioned in the laft paragraph. * The definition, which the Author gives of this fpecies in his Nolblogy,:U Dnpntte cvm tustiple- nmque sicca.

VI. 1374.3 A'HE Jterm of afthma has been commonly appli- ed by the vulgar, and even by many writers on the Praaice of Phyfie, to every cafe of difficult breathing, that is, toJ every fpecies of Dyfpncea. The Methodical Nofologifts, alfo, have diftinguifhed Afthma from Dyfpncea chiefly^ and almoft fotely, by the former being the fame affeaion with the latter, but in a higher degree. Neither of thefe applications 0f the term feems to have been correa or pro- per. I am of opinion, that the term Afthma may be moft properly applied, and fhould be confined, to a cafe of dif- ficult breatnjhg that has peculiar fymptoms, and depends * It U defined, Dysfnaa cum tussifrtauente mt/cum -viscidttm copiostsm encifnte. t The remedies fof thl» pmpofit At£ imetics/rndarlfics, n( eMpecuwMfU; formula of Wrick may be feem in the Motes on Article ipoc. | It b defined, Byspmaa arm urimphttn^tt trdemant: pedum, tint fiuctuatime in peelere, vel ahU (baracteristicis hydrotheracis signis. rfon fails into a much wifhed for fleep. ..;;'• >K *'• * This defcription of the difeafe under connderatfoh ts eXcenenV K : I1 RACTIGE 137S.] During thefe fits the puiie often continues in its natural ftate; but in fome perfions the fits are attended with a frequency of pulfe, and with fome heat and thirft, as marks of fume degree of fever. If urine be voided at the beginning of a fit, it is commonly in confide;, iblc quantity, and with little colour or odour; but, after the fit is over, the urine voided is in the ordinary quantity of a high colour, and fometimes depofits a fediment. In fome perfons, during the fit, the face is a little flufhed and turgid; but more commonly it is fomewhat pale and fhnmk. 1379.] After fome fleep in the morning, the patient, for the reit 01 the day, continues to have more free and eafy breathiivj, but it is feldom entirely fuch. He ftill feels fome tiqhtnefs acrofs his breaft,-cannot breathe eafily in a horizontal pofture, and can hardly bear any motion of his body, without having his breathing rendered more difficult and uneafy. In the afternoon he has an unufual flatulen- cy of his ftomach, and an unufual drowfinefs; and, very frequendy, thefe fymptoms precede?!the firft attacks of the difeafe. But, whether thefe fymptoms appear or not, the difficulty of breathing returns towards the evening; and then fometimes gradually increates, till it becomes as vio- lent as in the night before: or if, during the day, the diffi- culty of breathing has been moderate, and the perfon got fome fleep in the firft part of the night, he is, however, waked about midnight, or at fome time between midnight and two o'clock in the morning; and is then fuddenly feiz- edwith a fit of difficult breathing, which 111ns the fame courfe as the night before. 1380.] In this manner fits return for feveral nights fuc- cefiivdly: but generally, after fome nights paffed in this way, the fits fuffer more confiderable renditions. This ef- pecially happens when the remifiions are attended with a more copious expectoration in the mornings, and that this continues from time to time throughout the day. In thefe circumftances, afthmatics, for a long time after, have na& only more eafy days, but enjoy alfo nights of entire fleep, without the recurrence of the-difeafe. 1381.] When this difeafe, however, has once taken place in the manner above defcribed, it is ready to return at times for the whole of life after. Thefe returns, however, hap- pen with different circumftances in different pericm.-. OF PHYSIC. 137 1382.] In fome perfons the fits are readily excited by external heat, whether ofthe weather or of a. warm cham- ber, and particularly by warm bathing; In fuch perfon j fits are more frequent in fummer,.and particularly during tjjp dog-days, than at other colder feafons. The faiae per- fons are alfo readily affeaed by changes of the v. eather; efpecially by fudden changes made from a colder to a warm- er, or what is commonly the fame thing, from a heavier to a lighter atmofphere. The fame perfons are alfo affeaed by every circumftance ftraitenir.g the capacity of the tho- rax, as by any ligature made, or even by a plaiftcr laid upon it; and a like effea happens from any increafed bulk of the ftomach, either by a full meal, or by air cpjjected in it. They are likewife much affeaed by cxercife, or what- ever elfe can hurry the circulation of the blood. 1383.] As afthmaticftfs feem thus to depend upon fome fulnefs of the veflels of the lungs, it is probable that an ob- ftruction of perfpiration, and the blood being lefs determin- ed to the furface of the body, may favor an accumulation in the lungs, and thereby be a means of exciting afthma. This feems to be the cafe of thofe afthmatics who have fits moft frequently in the winter feafon, and who haye com- monly more of a catarrhal affeaion accompanying the afthma; which therefore occurs more frequently in winter, and more manifeftly from the application of ccld.- 1384.J Bcfide thefe cafes of afthma excited by heat or cold, there arc others, in which the fits are efpecially excit- ed by powers applied to the nervous fyftem; as by paffions of the mind, by particular odours, and by irritations of fmoke and duft. That this difeafe is an affection of the nervous fyftem, and depending upon a mobility of the moving fibres ofthe lungs', appears pretty clearly from its being frequently attended with other fpafmodic affeQaons depending upon mobility; fuch as hyfteria, hypochondria- fis, dyfpepfia, and atonic gout. 1385.] From the whole of the hiftory of afthma now delivered, I think it will readily appear, that the proximate caufe of this difeafe is a preternatural, and in fome meafure a fpafmodic, conftriaion of the mufcular fibres of the bronchia?; which not only prevents the dilatation of the bronchiae neceffary to a free and full infpiration, biit gives alfo a rigidity which prevents a full and free exfpiration. 13S PRACTICE This preternatural conftriftidh, like many other convulfive arid fpafmodic affections, is readily excited by a turgef- cenfe of the blood, or other caufe of any unufual fulnefs and diftention of the veffels of the lungs. 1386.] This difeafe, as coming by fits, may be generally diftinguifhed from moft other fpecies of dyfpncea, whoie caufes being more conftantly applied, produce therefore a more conftant difficulty of breathing. There may, how- ever, be fome fallacy in this matter, as fome of thefe caufes may be liable to have abatements and intenfities, whereby the dyfpncea produced by them may feem to come by fits; but I believe it is feldom that fuch fits put on the appear- ance of the genuine afthmatic fits defcribed above. Perhaps, however, there is ftill another cafe that may give more dif- ficulty ; and that is when feveral of the caufes,*which we have affigned as caufes of feveral ofthe fpecies of difficult breathing referred to the genus of Dyfpncea, may have the effea of exciting a genuine afthmatic fit. Whether this Can happen to any but the peculiarly predifpofed to afth- ma, I am uncertain; and therefore, whether in any fuch cafes, the afthma may be confidered as fymptomatic ; or if, in all fuch cafes, the afthma may not ftiil be confidered and treated a< an idiopathic difeafe. 1387. J The afthma, though often threatening immediate" death, feldom occafions it, and many perfons have lived tong under this difeafe. In many cafes, however, it does prove fatal; fometimes very quickly, and perhaps always at length. In fome young perfons it has ended foon, by occafioning a phthifis pulmonalis. After a long continu- ance, it often ends in a hydrothotax ; and commonly, by occafioning fome aneurrfm of the heart or great veffels, it thereby proves fatal. 1388.] As it is feldom that an afthma has been entirely cured ; I therefore cannot propofe any method of cure which experience has approved as generally fuccefsful. But the difeafe admits of alleviation in feveral refpeas from the ufe of reiriedijgs; and my bufinefs now fhall be chiefly to offer fome Remarks upon the choice and ufe of the remedies which have^neen commonly employed in cafes of afthma. ljj&q.] As the danger of an afthmatic fit arifes chiefly from the difficulttranfirmffion ofthe blood through the vef- fels ofthe lungs, threatening fuffocation; To the moft pro- u * I'WiSlC. W bable means of obviating this feems to be blood-letting; anf fits, blood-let.. ^ing cannot be frequently repeated without exhaufting and weakening the patient too much. It is further to be obfer- ved that |poodletting is not fo neceffary as might be ima- gined, as the paflage pf the blood through the lungs is not fo much interrupted as has been commonly fuppofed- This I particularly conclude from hence, that, inftead o.l the fuffufion of face, which is the ufual effea of fuch inter: ruption, the face, in afthrpatk fits, is often flirunk and pate* I conclude the fame alfo from this, that, in afthmatic fits* blood-letting does not commonly give fo much relief as, upon the contrary fuppofition, might be expeaed. 1390.] As I have alledged above, that a turgefcence of the blood is frequently the exciting caufe of afthmatic fit.:, fo it might be fuppofed, that a plethoric ftate of the fyftem might have a great fhare in producing a turgefcence of the blood in the lungs; and. efpecially, therefore, that blood- letting might be a proper remedy in afthma. I allow it to be fo in the firft attacks ofthe difeafe: but as the difeafe, by continuing, generally takes off the plethoric ftate of the fyftem; fo, after the difeafe has continued for fome time, I alledge that blood-letting becomes lefs and lefs neceffary. 1391. J Upon the fuppofition of afthmatics being in a plethoric ftate, purging might be fuppofed to prove a re- medy in this difeafe: but, both becaufe the fuppofition is not commonly well founded, and becaufe purging is feldom found to relieve the veffels of the thorax, this remedy has not appeared to be well fuited to afthmatics* and large purging has always been found to do much harm. But as afthmatics are always hurt by the ftagnation and accumula- tion of matters in the alimentary canal, fo coftivenefs.muft fee avoided, and an open belly proves ufeful. In the time of fits, the employment'of eniollient and moderately laxa- tive glyfters* has been found to give confiderable relief. 130,2.] Asa flatulency ofthe ftomach, and other fymp. • # A glyfter of milk, with a little fait, is generally fufficient.-—The coftivenefs may be remove* by mucilaeSiibu* laxatives of thettdlder kKd, as manu», caifai,*&Cv or by.a proper attention to diet!, especially 6y ufing the pulps of particular fruiu, at prunes or raifiitt bailed in barley-wares; roaifce* applet eatciWthinrowa fugar, «c* U PRACTICE kmns of indigeftion, are frequently attendants of afthma, and verv troublcforr.c to afthmatics; fo, both for removing thefe fymptoms, and for taking oft all determination to the lungs, the frequent ufe of gentle vomits* is proper in this difeafe. In certain cafes, where a fit was expeaed to com.e on in the courfe of the night, a vomit given in the evening has frequently feeined to prevent it. 1393.] Bliftering between the fhouldcrs, or upon the breaft, has been frequently employed to relieve afthmatics; but in the pure fpafmodic afthma we treat of here, I have rarely found blifters ufeful, either in preventing or reliev- ing fits. 1 394.] Iffues are certainly ufeful in obviating plethoia; but as fuch indications feldom arife in cafes of afthma, fo iffues have been feldom found ufeful in this difeafe. 1395.] As afthmatic fits are fo frequently excited by a turgefcence of the blood, fo the obviating and allaying of this by acids and neutral falts, feems to have been at all times the objea of praaitioners. See Fl o yer on the Asthma. 1396.J Although a plethoric ftate of the fyftem may icem to difpofe to afthma, and the occafional turgefcence of the blood may feem to be frequently the exciting caufe ofthe fit; yet it is evident, that the difeafe muft have arifen chiefly from a peculiar conftitution in the moving fibres of the bronchiae, difpofing them upon various occafions to fall into a fpafmodic conftriaion; and therefore, that the entire cure of the difeafe can only be expeaed from the correcting of that predifpofition, or from correcting the pre- ternatural mobility orirritability of thelungs in that refpea. 1397.] In cafes wherein this predifpofition depends up- on original conformation, the cure muft be difficult, and perhaps impoffiblc; but it may perhaps be moderated by the ufe of antifpafmodics. Upon this footing, various re- medies of that kind have been commonly employed, and particularly the fetid gums; but we have not found them of any confiderable efficacy, and have obferved them to be fometimes hurtful by their heating too much. Some other antifpafmodics which might be fuppofed powerful, fuch as mufk, have not been properly tried. The vitriolic ether has been found to give relief, but its effcBs are not lafting. » Vomits ought, in thefe cafes, to be mild. Some formula of tlcm arc given in one of the Note* ca article 185. OF PHYSIC. 141 1398.] As in other fpafmodic affeaions, fo in this, the molt certain and powerful antifpafmodic is opium* I have often found it effeaual, and generally fafe ; and if there have arifen doubts with refpea to its fafety, I believe they have arifen from not diftinguifh ing between certain pletho- ric and inflammatory cafes of dyfpncea, improperly named Afthma, and the genuine fpafmodic afthma we treat of here. 1399.] As in many cafes this difeafe. depends upon a predifpofition which cannot be correaed by our art, fo in fuch cafes the patient can only efcape the difeafe by avoid.- ing the occafional or exciting caufes, which I have endea^ voured to point out above, It is, however, difficult to give any general rules here$ as different afthmatics have their different idiofyncrafies with refpea to externals. Thus* one afthmatic finds him felf eafieit living in the midft a great city, while another cannot breathe but in the free air ofthe country* In the latter cafe, however, moft afthmatics bear the air of a low ground, if tolerable free and dry, better than that of the mountain* 1400.] In diet, alfo, there is fome difference tobe made with refpea to different afthmatics. None of them bear a large or full meal, or any food that is of flow and difficult folution in the ftomach ; but many of them bear animal food of the lighter kinds, and in moderate quantity. The ufe of vegetables which readily prove flatulent, are always very hurtful In recent afthma, and efpecially in the young and plethoric, a fpare, light, and cool diet is proper, and com- monly neceffary ; but after the difeafe has continued for years, afthmatics commonly bear, and even require, a tolerable full diet, though in all cafes a very full diet is very hurtful. 1401. J In drinking, water, or cool watery liquors, are the only fafe and fit drinks for afthmatics; and all liquors ready to ferment, and become flatulent, are hurtful to them. Few afthmatics can bear any kind of ftrong drink; and any excefs in fuch is always very hurtful to them. As afthmatics are commonly hurt by taking warm or tepid drink ; fo, both upon that.aecount and upon account of the liquors weakening the nerves of the ftomach, neither tea nor coffee is proper in this difeafe. # Theereateffieacvof opium, in cafe* of fpafmodic afthma, is fully confirmed by estperience. ft buRhT toTOven fn W doleS,'but not often repeated in the'day.

VII. ©f tfje Cfnncougi), or ^oopingcougfr, 14°3-3 X HIS difeafe is commonly epidemic, and mani- feftly contagious. It feems to proceed from a contagion of a fpecific nature, and of a finguiar quality, it does not, like moft other contagions, neceffarily produce a fever; nor does it, like moft others, occafion any eruption, or pro- duce otherwife any evident change in the ftate of the human fluids. It has, in common with the catarrhal contagion, and with that of the meafies, a peculiar determination to the lungs; but with particular effeas there, very different from thofe ofthe other two ; as will appear from the hiftory of this difeafe now to be delivered. 1404.] This contagion, like feveral others, affeas per- fons but once in the courfe of their lives ; and therefore, neceffarily, children are moft commonly the fubjeas of this difeafe : But there are many inftances of it occurring in perfons confiderably advanced in life; though it is pro- bable, that the further that perfons- are advanced in life, they are the lefs liable to be affeaed with this contagion. 1405*«] The difeafe commonly comes on with the ordi- nary fymptoms of a catarrh arifing from cold; and often, for many days, keeps entirely to that appearance ; and I have had inftances of a difeafe which, though evidently ari- fing from the chincough contagion, never put on any other form than that of a common catarrh. This, however, fel- dom happens; for, generally in the fecond, and at fartheft in the third week after the attack, the difeafe puts on its pe- culiar and charaaeriftic fymptom, a convulfive cough. This is a cough in which the exfpiratory motions peculiar to coughing are made with more frequency, rapidity, and vio- lence, than ufual. As thefe circumftances, however, in dif- ferent inftances of coughing, are in very different degrees; fo no exaa limits can be put to determine when the cough can be ftriaiy faid to be convulfive; and it is therefore OF PHY.SIC. 143 efpecially by another circumftance that the chincough is diftinguifhed from every other form of cough. This cir- cumftance is, when many exfpiratory motions have been convulfively made, and thereby the air is in great quantity thrown out from the lungs, a full infpiration is neceffarily and fuddenly made; which, by the air ruffling in through the glottis with unufual velocity, gives a peculiar found. This found is fomewhat different in different cafes, but is in general called a Hoop; and from it the whole of the dif- eafe is called the Hooping Cough. When this fonorous infpiration has happened, the convulfive coughing is again renewed, and continues in the fame manner as before, till a quantity of mucus is thrown up from the lungs, or the contents of the ftomach are thrown up by vomiting. Ei- ther of thefe evacuations commonly puts an end to the coughing, and the patient remains free from it for fome time after. Sometimes it is only after feveral alternate fits of coughing and hooping that expeaoration or vomiting takes place; but it is commonly after the fecond coughing that thefe happen, and put an end to the fit. 1406.] When the difeafe, in this manner, has taken its proper form, it generally continues for a long time after, and generally from one month to three; but fometimes much longer, and that with very various circumftances. 1407. J The fits of coughing return at various intervals, rarely obferving any exaa period. They happen frequent- ly in the courfe of the day, and more frequently ftill in the courfe of the night. The patient has commonly fome warning of their coming on; and, to avoid that violent and painful concuffion which the coughing gives to the whole body, he clings faft to any thing that is near to him, or de- mands 10 be held faft by any perfon that he can come at. When the fit is over, the patient fometimes breathes faft, and feems fatigued for a little after: but in many this ap- pears very little; and children are commonly fo entirely relieved, that they immediately return to their play, or what elfe they were occupied in before. 1408.] If it happens that the fit of coughing ends in vo- miting up the contents of the ftomach, the patient is com- monly immediately after feized with a ftrong craving and demand for food, and takes it in very greedily. 1409.] At the firft coming on of this difeafe, the expec- 144 PRACTICE toration is fometimes none at all, or of a thin mucus only; and while this continues to be the cafe, the fits of coughing are more violent, and continue longer; but commonly the expeaoration foon becomes confiderable, and a very thick mucus, often in great quantity, is thrown up; and as this is more readily brought up, the fits of coughing are of fhort- er duration. 1410.], The violent fits of coughing frequently interrupt the free tranfmiffion of the blood through the lungs, and thereby the free return of blood from the veffels ofthe head. This occafions that turgefcence and fuffufion of face which commonly attends the fi ts of coughing, and feems to occafion alfo thofe eruptions of blood from the nofe, and even from the eyes and ears, which fometimes happen in this difeafe. 1411.] This difeafe often takes place in the manner we have now defcribed, without any pyrexia attending it; but, though Sydenham had feldom obferved it, we have found the difeafe very frequently accompanied with pyrexia, fometimes from the very beginning, but more frequently only after the difeafe had continued for fome time. When it does accompany the difeafe, we have not found it appear- ing under any regular intermittent form. It is conftantly in fome degree prefent; but with evident exacerbations to- wards evening, continuing till next morning. 1412.} Another fymptom very frequently attending the chincough, is a difficulty of breathing; and that not only immediately before and after fits of coughing, but as con- ftantly prefent, though in different degrees in different per- fons. I have hardly ever feen an inftance of a fatal chin- cough, in which a confiderable degree of pyrexia and dy- fpncea had not been for fome time conftantly prefent. 1413. J When by the power of the contagion this dif- eafe has once taken place, the fits of coughing are often re- peated, without any evident exciting caufe : But in many cafes, the contagion may be confidered as giving a predif- pofition only ; and the frequency of fits depends in fome meafure upon various exciting caufes; fuch as, violent exercife ; a full meal; the having taken in food of diffi- cult folution ; irritation ofthe lungs by duff, fmoke or dif- agreeable odours of a ftrong kind : and efpecially any con-. {iderable emotion of the mind. 1414.] Such are the chief circumftances of this di^afe. OF PHYSIC. 145 and it is of various event; which, however, may be com- monly forefecn by attending to thefollowing confiderations. The younger that children are, they are in the greater danger from this difeafe ; and of thofe to whom it proves fatal, there are many more under two years old than above it. The older that children are, they are the more fecure a- gainlt an unhappy event ; and this I hold to be a very ge- neral rule, though I own there are many exceptions to it. Children born of phthifical and afthmatic parents are in the greateit danger from this difeafe. When the difeale, beginning in the form of a catarrh, is attended with fever and difficult breathing, and with little expeaoration, it often proves fatal, without taking on the form of the hoopingcough; but, in moft fuch cafes, the coming on ofthe convulfive cough and hooping, bringing on at the fame time a more free expeaoration, generally re- moves the danger. When the difeafe is fully formed, if the fits are neither frequent nor violent, with moderate expeaoration, and the patient, during the intervals of the fits, is eafy, keeps his ap- petite, gets fleep, and is without fever or difficult breathing, the difeafe is attended with no danger; and thefe circum- ftances becoming daily more favorable, the difeafe very foon fpontaneoufly terminates. An expeaoration, either very fcanty or very copious, is attended with danger; efpecially if the latter circumftance is attended with great difficulty of breathing. Thofe cafes in which the fits terminate by a vomiting, and are immediately followed by a craving of food, are generally without danger. A moderate hemorrhagy from the nofe often proves falu- tary ; but very large hemorrhagies are generally very hurtful. This difeafe coming upon perfons under a ftate of much debility, has very generally an unhappy event. The danger of this difeafe fometimes arifes from the vio - lence ofthe fits of coughing, occafioning apoplexy, epilep- fy, or immediate fuffocation: But thefe accidents are very rare; and the danger of the difeale feems generally to be in proportion to the fever and dyfpncea attending it. 1415. J The cure of this difeafe has been always confi- dered as difficult, whether the purpofe be to obviate its fa- tal tendency when it is violent3 or merely to fhor/-i «'^ U6 PRACTICE courfe of it when it is mild. When the contagion is recent, and continues to aa, we neither know how to correa, nor how to expel it; and therefore the difeafe neceffarily con- tinues for fome time: But it is probable, that the conta- gion in this as in other inftances ceafes at length to aa; and that then the difeafe continues, as in other convulfive affections, by the power of habit alone. 1416. j From this view of the matter I maintain, that the praaice muft be different, and adapted to two different indications, according to the period of the difeafe. At the beginning of the difeafe, and fome time after, the remedies to be employed muft be fuch as may obviate the violent effeas of the difeafe, and the fatal tendency of it; but, after the difeafe has continued for fome time, and is without any violent fymptoms, the only remedies which can be required are thofe which may interrupt its courfe, and put an entire ftop to it fooner than it would have fpontaneoufly ceafed. 1417.] Foranfwering the firft indication. In plethoric fubjects, or in others, when from the circumftances of the cough and fits it appears that the blood is difficultly tranf- mitted through the lungs, blood-letting* is a neceffary reme- dy; and it may be even neceffary to repeat it, efpecially in the beginning of the difeafe; But, as fpafmodic affe6tions do not commonly admit of much bleeding, fo it is feldom proper in the chincough to repeat this remedy often. 1418.] As coftivenefs frequently attends this difeafe, fo it is neceffary to obviate or remove it by laxatives employ- ed; and keeping an open belly is generally ufeful: But large evacuations in this way are commonly hurtful.t 1419. J To obviate or remove the inflammatory deter- mination to the lungs that fometimes occurs in the difeafe, bliftering is often ufeful, and even repeated bliftering has been of fervice; but iffues have not fo much effea, and fhould by no means fuperfede the repeated bliftering that may be indicated. When blifters are proper, they are more effeaual when applied to the thorax, than when ap- plied to any diftant parts. 1420.] Of all other remedies, emetics are the moft ufe- ful in this difeafe; both in general by interrupting the re- * Bleeding, in thefe cafes, is beft performed by leeches; and they feem to give greater relief whea applied about the neck than on any other part. t In general, the belly may be kept open by a proper attention to diet: roafted apples, eaten with hrown fugar, ftewed prunes, and other funilar food, which children generally devour with avidity, fufficiently anfiver the purpose of removing or preventing coftivenefs. O F P H Y S I C. 147 turn of fpafmodic affeaions", and in particular by deter- mining very powerfully to the furface of the body, and thereby taking off determinations to the lungs. For thefe purpofes, I think, full vomiting is frequently to be employ- ed; and, in the intervals neceffary to be left between the times of full vomiting, naufeating dofes of the antimonial emetics may be ufeful.* I have never found the sulphur auratum, fo much praifed by Cloffius, to be a convenient medicine, on account of the uncertainty of its dofe; and the tarter emetic employed in the manner direaed by the late Dr. Fothergill, has appearad*to be more ufeful. 1421.] Thefe are the remedies to be employed in the firft: ftage of the difeafe for obviating its fatal tendency, and putting it into a fafe train. But in the fecond ftage, when I fuppofe the contagion has ceafed to aa, and that the dif- eafe continues merely by the power of habit, a different indication arifes, and different remedies are to be employed. 1422.] This difeafe, which often continues for a long time, does not, in my opinion, continue during the whole of that time in confequence of the contagion's remaining in the body, and continuing to aa in it. That the difeafe does often continue long after the contagion has ceafed to aa, and that too by the power of habit alone, appears to me proba- ble from hence, that terror has frequently cured the difeafe; that any confiderable change in the ftate of the fyftem, fuch as the coming on of the fmall-pox, has alfo cured it; and laftly, that it has been cured by antifpafmodic and tonic medicines ; whilft none of all thefe means of cure can be fuppofed either to correa or to expel a morbific matter, though they are evidently fuited to change the ftate and ha- bits of the nervous fyftem. 1423.] From this view we are direaed to the indication that may be formed, and in a great meafure to the remedic which may be employed in what we fuppofe to be the fe cond ftage of the difeafe. It may perhaps be alledged, thai this indication of fhortening the courfe of the difeale is not » The method of giving tartar-emetic in naufeating dofes has been frequently mentioned in pre- ceding notes ; but in cafes of chincough, where children are generally our patients, we arc under the neceffity of varying the dofes to tho age and conititution. When the child u under s year old, wc oueht to ufe the weak folution of tartar-emetic, fpecified in the end of the lalt note on article iHs, in repeated dofes cf a table-fpoonful every ten or fifteen minutes, till it operates.

A violent vomiting was produced, and the child died fuddenly, during the action of the medicine: on infpecling the body after death, we found the ftomach burft, there being In it a laceration th»t admitted two fingers. The nupection0. this body has always made me extremely cautious in adminiftering emetics to y«wng children. 14& PRACTICE 'very important or neceffary, as it fuppofes that the danger or violence is over, and, in confequence, that the difeafe w;ll foon fpontaneoufly ceafe. The laft fuppofition, how- ever, is not well founded; as the difeafe, like many other convulfive and fpafmodic affeaions, may continue for a long time by the power of habit alone, and by the rcpetU tion of paroxyfms may have hurtful effeas; more efpe- cially as the violence of paroxyfms, and therefore their hurtful effeas, may be much aggravated by various exter- nal caufes that may be accidentally applied. Our indica- tion, therefore, is proper; and we proceed to confider the feveral remedies which may be employed to anfwer it. 1424.] Terror may poffibly be a powerful remedy, but it is difficult to meafure the degree of it that fhall be pro- duced ; and, as a flight degree of it may be ineffectual, and a high degree of it dangerous, I cannot propofe to employ it. 1425.J The other remedies which we fuppofe fuited to our fecond indication, and which indeed have been frequent- ly employed in this difeafe, are antifpafmodics or tonics. Of the antifpafmodics, caftor has been particularly re* commended by Dr. Morris; but in many trials we have not found it effeaual. With more probability mufk has been employed : but whether it be from our not having it of a genuine kind, or not employing it in fufficiently large dofes, I cannot deter- mine ; but wc have not found it commonly fuccefsful. Of antifpafmodics, the moft certainly powerful is opium : and when there is no confiderable fever or difficulty of breath- ing prefent, opium has often proved ufeful in moderating the violence of the chincough; but I have not known it employed fo as entirely to cure difeafe. If hemlock has proved a remedy in this difeafe, as we muft believe from Dr. Butter's accounts, I agree with that author, that it is to be confidered as an antifpafmodic. Upon this fuppofition, it is a probable remedy ; and from the accounts of Dr. Butter and fome others, it feems to have been often ufeful: but, in our trials, it has often difap- pointed us, perhaps from the preparation of it not having been always proper.* 1426.] Of the tonics, I confider the cupmofs, formerly # Experience has not found that any of the antifpafmodics have ever been emploved with much advantage in this difeafe. All of them are extremely naufeous, and confequently difficultly given to children who cannot well fwallow pills.

I confider the ufe of this medicine as the moft certain means of curing the difeafe in its fecond ftage; and when there has been little fever pre- fent, and a fufficient quantity ofthe bark has been given, it has feldom failed of foon putting an end to the difeafe. 1427.J When convulfive diforders may be fuppofed td continue by the force of habit alone, it has been found that a confiderable change in the whole of the circumftances and manner of life has proved a cure of fuch difeafes; and analogy has applied this in the cafe of the chincough fo far, that a change of air has been employed, and fuppofed to be ufeful. In feveral inftances I have obferved it to be fo; but I have never found the effeas of it durable, or fuffi- cient to put an entire ftop to the difeafe. Sect* III.

Probably they proceed from affeaions of different natures, and fhould therefore be dif- tinguifhed by different appellations > but I muft own that the utmoft precifion in this matter will be difficult. In my effay towards a methodical Nofology, I have, however, at- tempted it. For thofe pains that are either acute and pun- gent, or accompanied with a fenfe 0$ diftention, or with a fenfe of conftriaion, if they are at the fame time, not at- tended with any fenfe of acrimony or heat, I employ the appellation of Gaftrodynia, Toexprefs thofe painful or uneafy fenfations which feem to arife from a fenfe of acri- mony irritating the part, or from fuch a fenfe of heat as the application of acrids, whether externally or internally ap- plied, often gives, I employ the term of Cardial^ja; and by Vei.. Ik T 150 PRACTICE this I particularly mean to denote thofe feelings which are expreffed by the term Heartburn in the Englifh language. I think the term Soda has been commonly employed by praaical writers to exprefs an affeaion attended with feel- ings of the latter kind. 1429.] Befide the pains denoted by the terms Caftro- dynia, Periadynia, Cardialgia, and Soda, there is, I think, another painful fenfation different from all of thefe, which is named by Mr. Sauvages Pyrofis Suecica; and his account of it is taken from Linnaeus, who names it Cardialgia Spu- tatoria. Under the title of Pyrofis Mr. Sauvages has form- ed a genus, of which the whole of the fpecies, except the eighth, which he gives under the title of Pyrofis Suecica, are all of them fpecies of the Gaftrodynia or of the Cardi- algia ; and if there is a genus to be formed under the title of Pyrofis, it can in my opinion comprehend only the fpe- cies I have mentioned. In this cafe, indeed, I own that the term is not very proper ; but my averfion to introduce new names has made me continue to employ the term of Mr. Sauvages. 1430.] The Gaftrodynia and Cardialgia I judge to be for the moft part fymptomatic affeaions; and therefore have given them no place in this work : but the Pyrofis, as an idiopathic difeafe, and never before treated of in any fyftem, I propofe to treat of here. 1431.} It is a difeafe frequent among people in lower life, but occurs alfo, though more rarely, in people of bet- ter condition. Though frequent in Scotland, it is by no means fo frequent as Linnaeus reports it to be in Lapland. It appears moft commonly in perfons under middle age, but feldom in any perfons before theage ofpuberty. When it has once taken place, it is ready to recur occafionally for.a longtime after ; but it feldom appears in perfons con- fiderably advanced in life* It affeas both fexes, but more frequently the female. It fometimes attacks pregnant wo- men, and fome women only when they arc in that condi- tion. Of other women, it more frequently affeas the unmarried ; and of the married, moft frequently the bar- ren, I have had many inftances of its occurring in wo- men labouring under a fluor albus. 1432«J The fits of this difeafe ufually come on in the morning and afternoon, when the ftomach is empty „ The OF PHYSIC. 151 firft fymptom of it is a pain at the pit of the ftomach, with a fenfe of conftriaion, as if the ftomach was drawn towards the back; the pain is increafed by raifing the body into an erea pofture, and therefore the body is bended forward. This pain is often very fevere ; and, after continuing for fome time, it brings on an eruaation of a thin watery fluid in confiderable quantity. This fluid has fometimes an a- crid tafte, but is very often abfolutely infipid. The eruc- tation is for fome time frequently repeated ; and does not immediately give relief to the pain which preceded it,^ but does fo at length, and puts an end to the fit. 1433.] The fits of this difeafe commonly come on with- out any evident exciting caufe; and I have not found it fteadily conneaed with any particular diet. It attacks per- fons ufing animal food, but I think more frequently thofe living on milk and farinacea. It feems often to be excited. by cold applied to the lower extremities; and is readily excited by any confiderable emotion of mind. It is often without any fymptoms of dyfpepfia. 1434. J The nature of this affeaion is not very obvious; but I think it may be explained in this manner: It feems to begin by a fpafm of the mufcular fibres of the ftomach; which is afterwards, in a certain manner, communicated to the blood-veffels and exhalants, fo as to increafe the impetus of the fluids in thefe veffels, while a conftriaion takes place on their extremities. While therefore the increafed impe- tus determines a greater quantity than ufual of fluids into thefe veffels, the conftriaion upon their extremities allows only the pure watery parts to be poured out, analogous, as I judge, in every refpea, to what happens in the diabetes hyftericus. 1435.J The praaice in this difeafe is as difficult as the theory. The paroxyfm is only to be certainly relieved by opium. Other antifpafmodics, as vitriolic ether and vola- tile alkali, are fometimes of fervice, but not conftantly fo. Although opium and other antifpafmodics relieve the fits, they have no effea in preventing their recurrence. For this purpofe, the whole of the remedies of dyfpepfia have been employed without fuccefs. Of the ufe of the nux vomica, mentioned as a remedy by Linnaeus, I have had no experience. PRACTICE * CHAP. IX. Of tbe Colic. *43^«] A HE principal fymptom of this difeafe, is a pain felt in the lower helly. It is feldom fixed and pungent in one part, but is a painful diftention in fome meafure fpread- ing over the whole of the belly; and particularly with a fenfe of twitting or wringing round the navel. At the fame time, with this pain, the navel and teguments of the belly are frequently drawn inwards, and often the mufcles of the belly are fpafmodically contraaed, and this in feparate por- tions, giving the appearance of a bag full of round balls. 1437.] Such pains, in a certain degree, fometimes occur in cafes of diarrhoea and cholera; but thefe are lefs violent and more tranfitory, and are named Gripings. It is only when more violent and permanent, and attended with cof- tivenefs, that they conftitute colic. This is alfo commonly attended with vomiting, which in many cafes is frequently repeated, efpecially when any thing is taken down into the ftomach; and in fuch vomitings, not only the contents of the ftomach are thrown up, but alfo the contents of the du- odenum, and therefore frequently a quantity of bile. 1438.] In fome cafes of colic, the periftaltip motion is inverted through the whole length of the alimentary canal, in fuch a manner that the contents of the great guts, and therefore ftercoraceous matter, is thrown up by vomiting; and the fame inverfion appears ftill more clearly from this, that what is thrown into the reaum by glyfter is again thrown out by the mouth. In thefe circumftances of inverfion the difeafe has been named Ileus, or the Iliac Paffion; and this ha6 been fuppofed to be a peculiar difeafe diftina from co- lic; but to me it appears that the two difeafes are owing to $he fame proximate caufe, and have the fame fymptoms, pqly in a different degree. 1439.] The colic is often without any pyrexia attending it. Sometimes, however, an inflammation comes upon the part of the inteftine efpecially affeaed; and this inflamma- tion aggravates ail the fymptoms of the difeafe, being pro- bably what brings on the moft confiderable inverfion of the periftaltic motion; and, as the ftercoraceous vomiting is what efpecially diftingujfhes the ileus, this has been confw 15* OF PHYSIC 153 dered as always depending on an inflammation of the h> teftines. However, I can affirm, that as there are inflam- mations of the inteftines without ftercoraceous vomiting, fo I have feen inftances of ftercoraceous vomiting without inflammation; and there is therefore no ground for diftin- guifh ing ileus from colic, but as a higher degree of the fame affeaion. 1440.J The fymptoms of the colic, and the diffeaions of bodies dead of this difeafe, fhow very clearly that it de- pends upon a fpafmodic conftriaion of a part of the intef- tines; and that this therefore is to be confidered as the proxi- mate caufe ofthe difeafe. In fome of the diffeaions of perfons dead of this difeafe, an intus-fufception has been remarked to have happened ; but whether this be conftant- ly the cafe on all the appearances of ileus, is not certainly determined. 1441. J The colic has commonly been confidered as be- ing of different fpecies, but I cannot follow the writers on this fubjea in the diftinaions they have eftablifhed. So far, however, as a difference of the remote caufe confti- tutes a difference of fpecies, a diftinaion may perhaps be admitted ; and accordingly in my Nofology I have mark- ed feven different fpecies : But I am well perfuaded, that in all thefe different fpecies the proximate caufe is the fa:: ie, that is, a fpafmodic conftriaion of a part of the inteftin"0; and confequently, that in all thefe cafes the indication f cure is the fame, that is, to remove the conftriaion me - tioned. Even in the feveral fpecies named Stercorea, Ccl- losa, and Calculosa, in which the difeafe depends upon h 1 obftruaion of the interline, I am perfuaded that thefe ob- ftruaions do not produce the fymptoms of colic, except- ing in fo far as they produce fpafmodic conftriaions ofthe inteftines; and therefore, that the means of cure in thefe cafes, fo far as they admit of cure, muft be obtained by the fame means which the general indication above-mentioned fuggefts. 1442.] The cure, then, of the colic univerfally, is to be obtained by removing the fpafmodic conftriaions ofthe inteftines; and the remedies fuited to this ptrpofe may be referred to three general heads: 1. The taking off the fpafm 1^ various anfifpafmodi^ powers. 4P ¥5-* PRACTICE ■ * 2. The exciting the aaion ofthe inteftines by purgatives. 3. The employing mechanical dilatation. a 443.J Before entering upon a particular account of thefe remedies, it will be proper to obferve, that in all cafes of violent colic, it is advifable to praaife blood-letting; both as it may be ufeful in obviating the inflammation which is commonly to be apprehended, and even as it may be a means of relaxing the fpafm of the inteftine. This remedy may perhaps be improper in perfons of a weak and lax habit, $mt in all perfons of tolerable vigour it will be a fafe reme- dy-; and in all cafes where there is the leaft fufpicion of an inflammation aaually coming on, it will be abfolutely ne- ceffary. Nay, it will be even proper to repeat it perha.ps feveral times, if, with a full and hard pulfe, the appearance of the blood drawn, and the relief obtained by the firft bleeding, fliall authorife fuch repetition. 1444. J The antifpafmodic powers that may be employed, are, the application of heat in a dry or humid form, the ap- plicationof blifters, the ufeof opium, and theufeof mild oils. The application of heat, in a dry form, has been employ- ed by applying to the belly of the patient a living animal, or bladders filled with warm water, or bags of fubftances which long retain their heat; and all thefe have fometimes been applied with fuccefs; but none of them feem to me fo powerful as the application of heat in a humid form. This may be employed either by the immerfion of a great part of the body in warm water, or by fomenting the belly with cloths wrung out of hot water. The immerfion has advantages from the application of it to a greater part of the bodyj and particularly to the lower extremities: But immerfion cannot always be conveniently praaifed, and fo- mentation may have the advantage of being longer continu- ed; and it may have nearly all the benefit of immerfion, if it be at the fame time applied both to the belly and to the lower extremities. 1445.] From confidering that the teguments of the lower belly have fuch a conneaion with the inteftines, as at the fame time to be affeaed with fpafmodic contra6tion, we perceive that blifters applied to the belly may have the effect of taking off the fpafms both from the mufcles of the belly and from theJnteftines; and accordingly, blif- tering has often been enjoyed in the colic with advantage. OF PHYSIC. i'.f * =?== m Analogous to this, rcbefacients applied to the belly have been frequently found ufeful. 1446.] The ufe of opium in the colic may feem to be an ambiguous remedy. Very certainly it may for fome time relieve the pain, which is often fo violent and urgent, that it is difficult to abftain from the ufe of fuch av remedy. At the fame time, the ufe of opium retards or fufpends the periftaltic motion fo much, as to allow the inteftines to fall into conftriaions; and may therefore, while it relieves the pain, render the caufe of the difeafe more ohftinatc. O^ this account, and further as opium prevents the opefatiow* of purgatives fo often neceffary in this difeafe, many prac- titioners arc averfe to the ufe of it, and fome entirely reject the ufe of it as hurtful. There are, however, others who think they can employ opium in this difeafe with much ad- vantage. In all cafes where the colic comes on without any pre- vious coftivenefs, and arifes from cold, from paffions ofthe mind, or other caufes which operate efpecially on the ner- vous fyftem, opium proves a fafe and certain remedy;, but in cafes which have been preceded by long coftivenefs, or where the colic, though not preceded by coftivenefs, has however continued for fornc days without a ftool, fo that a ftagnation of faeces in the colon is to be fufpeaed„4he ufe of opium is of doubtful effea. In fuch cafes, unlefs a* ftool has been firft procured by medicine, opium cannot be employed but with fome hazard of aggravating the dif- eafe. However, even in thofe circumftances of cofti^rev nefs, when, without inflammation, the violence of the fpafm is to be fufpeaed, when vomiting prevents .the exhibition of purgatives, and when with all this the pain is extremely urgent, opium is to be employed, not only as an anodyne, but alfo as an antifpafmodic, neceffary to favor the opera- tion of purgatives; and may be fo employed, when, either at the fame time with the opiate, or not long after it, a pur- gative can be exhibited. Is the hyofcyamus, as often fhowing, along with its nar- coticj a purgative quality, better fuited to this difeafe than opium ? 1447.] It is feemingly on good grounds that fevcral praaitioners have recommended the large ufe of mild oils in this difeafe, both as antifpafmocScs and as laxatives; and, L54 PRACTICE where the palate and ftomach could admit them, I have found them very ufeful. But as there are few Scottifh ftomachs that can admit a large ufe of oils, I have had few opportunities of employing them. 144 8. J The fecond fet of remedies adapted to the cure of colic, are purgatives; which, by exciting the aaion of the inteftines, either above or below the obftruaed place, may remove the conftriaion; and therefore thefe purga^ rives may be given either by the mouth, or thrown by glyf- ters into the anus. As the difeafe is often feated in the greatiguts; as glyfters, by having a more fudden operation, may give more immediate relief; and as purgatives given by the mouth are ready to be rejeaed by vomiting; fo it is common, and indeed proper, to attempt curing the colic in the firft place by glyfters. Thefe may at firft be of the mildeft kind, confifting of a large bulk of water, with fome quantity of mild oil; and fuch are fometimes fufficiently efficacious: However, they are not always fb; and it is commomy neceffary to render them more powerfully fti- mulant by the addition of neutral falts, of which the moft powerful is the common or marine fait. If thefe faline glyfters, as fometimes happens, are rendered again too quickly, and on this or otherwife are found ineffectual, it may be proper, inftead of thefe falts, to add to the glyfters an infufion of fenna, or of fome other purgative that can be extraaed by water. The antimonial wine* may be fometimes employed in glyfters with advantage. Hardly auy glyfters are more effeaual than thofe made of turpen- tine propcrlyt prepared. When all other injeaions are found ineffetlual, recourfe is to be had to the injeaion of tobacco fmoke; and, when even this fails, recourfe is to be had to the mechanical dilatation to be mentioned hereafter* 1449. J ^s gtyfters often fail altogether in relieving this difeafe, and as even when they give fome relief they are often imperfea in producing a complete cure; fo it is ge- * Tartar emetic is furer than the antimonial wine; but it is a very violent remedy, and ought tw be ufed with caution even in glyfters.

The more powerful of thefe, or, as they are called, the Draftic Purgatives, may be fometimes neceffary; but their ufe is to be avoided, both becaufe they are apt to be rejeaed by vomiting, and becaufe when they do not fuc- ceed in removing the obftruaion they are ready to induce an inflammation. Upon this account it is ufual, and in- deed proper, at leaft in the firft place, to employ the milder and lefs inflammatory purgatives. None have fucceeded,. with me better than the chryftals of tartar,* becaufe this medicine may be given in fmall but repeated dofes to a confiderable quantity; and under this management it is the purgative leaft ready to be rejeaed by vomiting, and much lefs fo than the other neutral falts. If a ftronger purgative be required, jalap,f properly prepared, is lefs offenfive to the palate, and fits better upon the ftomach, than moft other powerful purgatives. On many occafions of colic, nothing is more effeaually purgative than a large dofe of calomel.J Some praaitioners have attempted to remove the obftruaion of the inteftines by antimonial emetics [| exhibited in fmall dofes, repeated at proper intervals; and when thefe dofes are not entirely rejeaed by vomiting, they often prove effeaual purgatives. When every purgative has failed, the aaion of the in- teftines has been effeaually excited by throwing cold wa- ter on the lower extremities. 1450. J The third means of overcoming the fpafm of trie inteftines in this difeafe, is by employing a mechanical di- latation; and is has been frequently fuppofed that quick- filver, given in large quantity, might operate in this man- * Cryftals of tartar may be given in dofes of two drachms each, repeated every two hours or of- tener.

It is better to avoid them altogether, for they may do much mifehief. Vol. 11. U 158 PRACTICE ner. I have not, however, found it fuccefsful; and the theory of it is with me very doubtful. Some authors have mentioned the ufe of gold and filver pills, or balls, fwal- lowed down; but I have no experience of fuch praftices, and I cannot fuppofe them a probable means of relief. 1451.] Another means of mechanical dilatation and a more probable meafure, is by injeaing a large quantity of 4 warm water by a proper fyringe, which may throw it with fome force, and in a continued ftream, into the reaum. Both from the experiments reported by the late Mr. De Haen, and from thofe I my felf have had occafion to make, I judge this remedy to be one of the moft powerful and "1 effeaual.* 1452.] I have now mentioned all the feveral means that may be employed for the cure ofthe colic, confidered as a genus; but before I quit this fubjea, it may be expcaed that I fhould take notice of fome of the fpecies which may feem to require a particular confideration. In this view it may be expeaed that I fhould efpecially take notice of that fpecies named the Colic of Poitou, and particularly known in England by-the name of the Devonfhire Colic. 1453. J This fpecies of the difeafe is certainly a peculiar 1 one, both in refpea to its caufe and its effeas; but, as to > the firft, it has been lately fo much the fubje£t of investi- gation, and is fo well afcertained by the learned phyficians- J Sir George Baker and Dr. Hardy, that it is unneceffary for me to fay any thing of it here. With refpea to the cure of it,t fo far as it appears in the form of a colic, my want of experience concerning it does not allow me to fpeak with any confidence on the fub- jea; but, fo far as I can learn from others, it appears to me, that it is to be treated by all the feveral means that I have propofed above for the cure of colic in general. How far the peculiar effeas of this difeafe are to be cer- # It is to be thrown up, by means of a large fyringe, in fuch quantities, that the patient begins to feel a fenfe of uneafinefs from the great diftention which it occafions. Some patien ts have borne two gallons to be injected, and the cafes were attended with the defired fuccefs. The cafes in which thefe large injeaions are moft ufeful, are thofe in which hardened feces are accumulated in thc~ c 'on. The warm water anfwers two intentions, viz. dilating the paflage, and foftening the faeces. -1 n the early ftage of this difeafe, the belly is to be kept open by the mildeft laxatives, and a milk diet ftriftfy ufed. The following formula anfwers extremely well : JBc- Mannx, 01. Clivar. aa 5*u 21. f. Linftus.

X. fl)f tU C&olcra. a454«] IN this difeafe, a vomiting and purging concur- ring together, or frequently alternating with one another, are the chief fymptoms. The matter rejeaed both up- wards and downwards appears manifeftly to confift chiefly of bile. 1455-j From this laft circumftance I conclude, that the difeafe depends upon an increafed fecretion of bile, and its copious effufion into the alimentary canal: and, as in this it irritates and excites the motions above mentioned, I infer, that the bile thus effufed in larger quantity is at the fame time alfo of a more acrid quality. This appears likewife from the violent and \tery painful gripings that at- tend the difeafe, and which we can impute only to the vio- lent fpafmodic contraaions of the inteftines that take place here. Thefe fpafms are commonly communicated to the abdominal mufcles, and very frequently to thofe of the extremities. 145S.J In the manner now defcribed, the difeafe fre- quently proceeds with great violence, till the ftrength of the patient is greatly, and often fuddenly, weakened; while a coldnefs of the extremities, cold fweats, and faintings, coming on, an end is put to the patient's life, fometimes in the courfe of one day. In other cafes the difeafe is lefs violent, continues for a day or two, and then ceafes by degrees; though fuch recoveries feldom happen without the afliftance of remedies. 1457.J Tne attac^s of trus difeafe are feldom accompa- nied with any fymptoms of pyrexia; and though, during the courfe of it, both the pulle and refpiration are hurried and irregular, yet thefe fymptoms are generally fo entirely removed by the remedies that quiet the fpafmodic affeaion peculiar to the difeafe, as to leave no ground for fuppofing that it had been accompanied by any proper pyrexia. 1458.] This is a difeafe attending a very warm ftate of 100 PRACTICE the air; and, in very warm climate?, it may perhaps ap- pear at any time of the year: But even in fuch climates it is moft frequent during their warmeft feafons; and in tern- perate climates, it appears only in the warm feafons. Dr. Sydenham confidered the appearances of this difeafe in England to be confined to the month of Au^uft; but he himfelf obferved it to appear fometimes towards the end of fummer, when the feafon was unufually warm; and that, . in proportion to the heat, the violence of the difeafe was greater. Others have obferved that it appeared more early in fummer, and always fooner or later, according as the great heats fooner or later fet in. 1459.} From all thefe circumftances, it is, I think, ve- ry evident, that this difeafe is the effea of a warm atmof- phere, producing fome change in the ftate of the bile in the human body: And the change may confift, either in the matter ofthe bile being rendered more acrid, and there- by fitted to excite a more copious fecretion ; or, in the fame matter, its being prepared to pafs off in larger quan- tity than ufual. 1460.} It has been remarked, that in warm climates and feafons, after extremely hot and dry weather, a fall of rain cooling the atmofphere feems efpecially to bring on this difeafe ; and it is very probable that an obfiru&ed perfpi- ration may have alfo a fhare in this, though it is alfo cer- tain that the difeafe does appear when no change in the temperature of the air, nor any application of cold has been obferved. 1461.J It is poffible, that, in fome cafes, the heat ofthe feafon may give only a predifpofition, and that the difeafe may be excited by certain ingefta or other caufes ; but it is equally certain, that the difeafe has occurred without any previous change or error, either in diet, or in the manner of life, that could be obferved. 1462.j The Nofologifts have conftituted a Genus un- der the title of Cholera, and under this have arranged as a fpecies every affeaion in which a vomiting and purging of any kind happened to concur. In many of thefe fpecies, however, the matter evacuated is not bilious; nor does the evacuation proceed from any caufe in the ftate of the atmofphere. Further, in many of thefe fpecies alfo, the vomiting which occurs is not an effential, but merely an OF PHYSIC. 1.4I accidental fymptom from the particular violence of the difeafe. The appellation of Cholera therefore fliould, in my opinion, be confined to the difeafe I have defcribed above; which by its peculiar caufe, and perhaps alfo by its fymptoms, is very different from all the otlier fpecies that have been affociated with it. I believe that all the other fpecies arranged under the title of Cholera by Sauvages or Sagar, may be properly enough referred to the genus of Diarrhcea; which we are to treat of in the next chapter. The diftinaion I have endeavoured to eftablifh between the proper Cholera, and the other difeafes that have fome- times got the fame appellation, will, as I judge, fuperfede the queftion, Whether the Cholera, in temperate climates, happens at any other feafon than that above affigned ? 1i^3-] In the cafe of a genuine cholera, the cure of it has been long eftablifhed by experience. In the beginning of the difeafe, the evacuation of the redundant bile is to be favored by the plentiful exhibition of mild diluents,* both given by the mouth, and injeaed by the anus; and all evacuant medicines, employed in ei- ther way, arc not only fuperfluous, but commonly hurtful. 1464.] When the redundant bile appears to be fuffici- ently wafhed out, and even before that, if the fpafmodic affeaions of the alimentary canal become very violent, and are communicated in a confiderable degree to other parts of the body, or when a dangerous debility feems to be in- duced, the irritation is to be immediately obviated by opiates in fufficiently large dofes, but in fmall bulk, and given either by the mouth, or by glyfter.t 1465.J Though the patient be in this manner relieved, it frequently happens, that when the operation of the opi- um is over, the difeafe fhows a tendency to return; and, for at leaft fome days after the firft attack, the irritability of the inteftines, and their difpofition to fall into painful fpafmodic contraaions, feem to continue. In this fitua- tion, the repetition of the opiates, for perhaps feveral # Thin rice gruel is as proper a mild diluent as any we can ufe; as is alfo water in which a cruft cf bread is boiled. A very fmall quantity of port wine may be added to thefe diluents if the pulle tie fmall or weak. t A pill confifting of a grain of opium may be given every two hours, and if it does not relieve ths fymptoms after the third orfourth repetition, we may inject the following glyfter : ft.

H52 PRACTICE days, may come to be neceffary; and as the debility com- monly induced by the difeafe favours the difpofition to fpafmodic affections, it is often ufeful and neceffary, to- gether with the opiates, to employ the tonic powers of the Peruvian bark.* CHAP. XI. ffif Diarrhoea or Loosene&s, 1466.] JL HIS difeafe confifts in evacuation by ftool, more frequent and of more liquid matter than ufual. This leading and characteristic fymptom is fo diverfified in it% degree, in its caufes, and in the variety of matter evacu- ated, that it is almoft impoffible to give any general hiftory of the difeafe. 1467.] It is to be diftinguifhed from dyfentery, by not being contagious; by being generally without fever; and by being with the evacuation of the natural excrements, which are, at leaft for fome time, retained in dyfentery. The two difeafes have been commonly diftinguifhed by the gripings being more violent in the dyfentery; and they are commonly lefs violent and lefs frequent in diarrhoea: but as they frequently do occur in this alfo, and fometimes -to a confiderable degree, fo they do not afford any proper diftinaion.t 1468.] A diarrhoea is to be diftinguifhed from cholera chiefly by the difference of their caufes; which, in cholera, is of one peculiar kind; but in diarrhoea is prodigioufly di'werfified, as we fhall fee prefently. It has been common to diftinguiffi cholera by the evacuation downwards being of bilious matter, and by this being always accompanied with a vomiting of the fame kind; but it does not univer- fally apply, as a diarrhoea is fometimes attended with vo- miting, and even of bilious matter. 1469.] The difeafe of diarrhoea, thus diftinguifhed, is very greatly diverfified; but in all cafes, the frequency of * The bark in there cafes is often fuccefsfully given alone with rhubarb, m in the following formula ft.

OF P H Y S I€. 163 ftools is to be imputed to a preternatural increafe of the „ periftaltic. motion in the whole, or at leaft in a confidera- ble portion, of the inteflinal canal. This increafed aaion is in different degrees, is often convulfive and fpafmodic, and at any rate is a motus abnormis : for which reafon, in the Methodical Nofology, I have referred it to the order k of Spafmi, and accordingly treat of it in this place. 1470.] Upon the fame ground, as I confider the difeafe named Lientery to be an increafed periftaltic motion over the whole of the inteftinal canal, arifing from a peculiar ir- ritability, I have confidered it as merely a fpecies of diar- rhoea. The idea of a laxity- of the inteftinal canal being ! /• the caufe either of lientery, or other fpecies of diarrhoea, . 'Appears to me without foundation, except in the fingle cafe of frequent liquid ftools from a palfy of the sphincter ani. 1471.] The increafed aaion of the periftaltic motion, I confider as always the chief part ofthe proximate caufe of diarrhoea: but the difeafe is further, and indeed chiefly, diverfified by the different caufes of this increafed aaion; which we are now to inquire into. 1472.] The feveral caufes of the increafed aaion ef the inteftines may be referred, I think, in the firft place, to two general heads. The first is, of the difeafes of certain parts of the body . which, either from a confent of the inteftines with thefe parts, or from the relation which the inteftines have to the: whole fyftem, occafion an increafed aaion in the intef- tines, without the transference of any ftimulant matter from the primary difeafed part to them. The second head of the caufes of the increafed aaion of the inteltines is the ftimuli of various kinds, which are ap- plied direaiy to the inteftines thtmfelves. 14:73-1 Thefe affeaions of other parts of the fyftem may affea the inteftines without the transference or application. . of any ftimulant matter, we learn from hence that the paf- fions ofthe mind do in fome perfons excite diarrhoea. 1474.] That difeafes in other parts may in like manner affea the inteftines, appears from the dentition of infants frequently exciting diarrhoea. I believe that the gout of- ten affords another inftance of the fame kind; and proba- bly there are others alfo, though not well afcertained. 16 i PRACTICE 1475.] The ftimuli (1472.) which may be applied to the inteftines are of very various kinds; and are either, 1. Matters introduced by the mouth. 2. Matters poured into the inteftines by the feveral ex- cretories opening into them. 3. Matters poured from certain preter-natural openings made into them in certain difeafes. 1476-.J Of thofe (1475, 1.) introduced by the mouth, the firft to be mentioned are the aliments commonly taken in. Too great a quantity of thefe taken in, often prevents their due digeftion in the ftomach; and by being thus fent in their crude, and probably acrid, ftate to the inteftines, they frequently excite diarrhoea. .The fame aliments, though in proper quantity, yet hav- ing too great a proportion, as frequently happens, of fa- line or faccharine matter along with them, prove ftimulant to the inteftines, and excite diarrhoea. But our aliments prove efpecially the caufes of diarrhoea, according as they, from their own nature, or from the weaknefs of the ftomach, are difpofed to undergo an undue degree of fermentation there, and thereby become ftimu- lant to the inteftines. Thus acefcent aliments are ready to produce diarrhoea; but whether from their having any di- reaiy purgative quality, or only as mixed in am over pro- portion with the bile, is not well determined. 1477.J Not only the acefcent, but alfo the putrefcent difpofition of the aliments, feems to occafion a\diarrhcea; and it appears that even the effluvia of putrid bodies, taken in any way in large quantity, "have the fame effect. Are oils or fats, taken in as a part of our aliments, ever the caufe of diarrhoea? and if fo, in what manner do they operate?* 1478.J The other matters introduced by the mouth, which may be caufes of diarrhoea, are thofe thrown in ci- ther as medicines, or poifons that have the faculty of fti- mulating the alimentary canal. Thus, in the lift of the Materia Medica, we have a long catalogue of thofe nam- ed purgatives; and in the lift of poifons, wc have many poffeffed of the fame quality* The former, given in a cer- quantity, occafion a temporary diarrhoea; and given in very large dofes, may occafion it in excefs, and continue # Rancid oils and fats certainly irritate the inteftines, and may therefore produce diarrhoea. 0 F P H Y S I c. les it longer than ufual, producing that fpecies of diarrhoea named a Hypercatharfis. 1479-J Tne matters (1475, 2.) poured into the cavity of the inteftines from the excretories opening into them, and which may occafion diarrhoea, are either thofe from the pancreatic or biliary dua, or thofe from the excreto- ries in the coats of the inteftines themfelves. 1480.] What changes may happen in the pancreatic juice I do not exaaiy know; but I fuppofe that an acrid fluid may iffue from the pancreas, even while ftill entire in its ftruaure; but more efpecially when it is in a fupporated, fcirrhous, or cancerous ftate, that a very acrid matter may be poured out by the pancreatic du6t, and occafion diar- rhoea. 1481.] Wre know well, that from the biliary dua the bile may be poured out in greater quantity than ufual; and there is little doubt of its being alfo fometimes poured out of a more than ordinary acrid quality. It is very probable, that in both ways the bile is frequently a caufe of diarrhoea. Though I have faid above;that diarrhoea may be com- monly diftinguifhed from cholera I muft admit here, that as the caufes produciiig that ftate ofthe bile which occafi- ons cholera, may occur in all the different poffible degrees of force, fo as, on one occafion, to produce the moft vio- lent and diftin£tfy marked cholera; but, upon another, to produce only the gentleft diarrhoea: which, however, will be the farfc&difeafe, only varying in degree: So I think it probable^.;.that in warm climates, and in warm feafons, a diairhazaj^iliosa of this kind may frequently occur, not to be always certainly diftinguifhed from cholera. However this may be, it is fufficiently probable, that, in fome cafes, the bile, without having been aaed upon by the heat of the climate or feafon, may be redundant and acrid, and prove therefore a particular caufe of diar- rhoea. 1482J Befide bile from the feveral caufes and in the conditions mentioned, the biliary dua may pour out pus, or other matter from abfeeffes in the liver, which may be the caufe of diarrhoea. Praaical writers take notice of a diarrhoea wherein a thin antl bloody liquid is difcharged; which they fuppofe ViL. II. X >r}6 PRACTICE to have proceeded, from the liver, and have therefore gii- ven the difeafe the name of Hepatirrhoea : but we have^iot met with any inftance of this kind; and therefore cannot properly fay any thing concerning it. 1483.] A fecond fet of excretories, from which matter is poured into the cavity of the inteftines, are thoTe from the coats of the inteftines themfelves; and are either the exhalants proceeding direaiy from the extremities of arte- teries, or the excretories from the mucous follicles: and / both thefe fources occur in prodigious number over the internal furface of the whole inteftinal canal. It is proba- ble that it is chiefly the effufion from thefe fources which, in moft inftances, gives the matter of the liquid ftools oc- curring in diarrhoea. 1484.] The matter from both fources may be poured out in larger quantity than ufual, merely by the increafed aaion of the inteftines, whether that be excited by the paf- fions of the mind (1473.) by difeafes in other parts of the fyftem (1472, 1.) or by the various ftimulants mentioned (1476.) and following; or the quantity of matter poured out may be increafed, notfo much by the increafed aaion of the inteftines, as by an increafea1 afflux of fluids from other parts of the fyftem. Thus, cold applied to the furface of the body, and fur> preffing perfpiration,. may determine a greater quantity of fluids to the inteftines. Thus, in the ischuria renalis, the urine taken into the- blood-veffels is fometimes determined to pafs off again by the inteftines. ^ In like manner, pus or ferum may be abforbed from the cavities in which they have been ftagnant, and be again poured out into the inteftines, as frequently happens, in particular with refpea to the water of dropfies. 1485.J It is to be obferved here, that a diarrhoea may * be excited not only by a copious afflux of fluids from other ! parts of the fyftem, but likewife by the mere determination of various acrid matters from the mafs of blood into the cavity of the inteftines. Thus it is fuppofed that the mor- bific matter of fevers is fometimes thrown o it into the ca- vity of the inteftines, and gives a critical diarrhoea: and whether I do or do not admit the doarine of critical eva~ cuations, I think it is probable that the morbific matter of O F P H Y S I C. 167 the exanthemata is frequently thrown upon the inteftines, and occafions diarrhoea. i486.] It is to me further probable, that the putrefcent matter diffufed over the mafs of blood in putrid difeafes, is frequently poured out by the exhalants into the inteftines, and pr6ves there the caufe, at leaft in part, of the diar- rhoea fo commonly attending thefe difeafes. 1487. J Upon this fubjea of the matters poured into the cavity of the inteftines, I have chiefly confidered them as poured out in unufual quantity, but it is probable that, for the moft part, they are alfo changed in their quality, and become of a more acrid and ftimulant nature; upon which account efpecially it is that they excite, or at leaft increafe a diarrhoea. 1488.] How far, and in what manner, the exhalant fluid may be changed in its nature and quality, we do not cer- tainly know: but with refpea to the fluid from the mu- cous excretories, we know, that, when poured out in un- ufual quantity, it is commonly, at the fame time, in a more liquid and acrid form; and may prove, therefore, confiderably irritating. 1489.] Though the copious effufion of a more liquid and acrid matter from the mucous excretories, be probably owing to the matter being poured out immediately as it is Jecreted from the blood into the mucous follicles, without being allowed to ftagnate in the latter, fo as to acquire that milder quality and thicker confiftence we commonly find in the mucus in its natural ftate; and although we might fuppofe the excretions of a thin and acrid fluid fhould al- ways be the effea of every determination to the mucous follicles, and of every ftimulant applied to them ; yet it is certain, that the reverfe is fometimes the cafe; and that, from the mucous follicles, there is frequently an increafed excretion of a mucus, which appears in its proper form of a mild, vifcid, and thickifh matter. This commonly occurs in the cafe of dyfentery ; and it has been obferved to give a fpecies of diarrhoea, which has been properly named the Diarrhoea Mucosa. 1490.] A third fource of matter poured into the cavity of theinteftines, and occafioning diarrhoea (1475.3 )is from thofe preternatural openings produced by difeafes in the inteftines or neighboring parts. Thus the blood-veffels on 158 PRACTICE the internal furface of the inteftines may be opened by ero- fion, rupture, or anaftomofis, and pour into the cavity their blood, which, either by its quantity, or by its acrimo- ny, whether inherent, or acquired by ftagnation, may fome- times give a diarrhoea evacuating bloody matter. This is what I think happens in that difeafe which has been called the Melcena or Morbus Niger. 1491.] Another preternatural fource of matter poured into the cavity ofthe inteftines, is the rupture of abfeeffes feated either in the coats ofthe inteftines themfelves, or in any ofthe contiguous vifcera, which, during an inflamed ftate, had formed an adhefion with fome part of the intef- tines. The matter thus poured into their cavity may be various; purulent, or famous, or both together, mixed at the fame time with more or lefs of blood; and in each of thefe ftates may be a caufe of diarrhoea. 1492.] Amonglt the ftimuli that may be direaiy applied to the inteftines, and which, by increafing their periftaltic motion, may occafion diarrhoea, I muft not omit to men- tion worms, as having frequently that effect. 1493.] I muft alfo mention here a ftate ofthe inteftines, wherein their periftaltic motion is preternaturally increaf- ed, and a diarrhoea produced; and that is, when they arc affeaed with an erythematic inflammation. With refpea _ to the exiftence of fuch a ftate, and its occafioning diar->3 rhoea, fee what is faid above in (398.) and following. WheAa ther it is to be confidered as a particular and diftina cafe^ of diarrhoea, or is always the fame with fome of thofe pro- duced by one or other of the caufes above-mentioned, I have not been able to determine. 1494.] Laftly, by an accumulation of alimentary or ojF other matter poured into the cavity of the inteftines from feveral of the fourcts above-mentioned, a diarrhoea may be efpecially occafioned when the abforption of the Meals, or of other abforbents, is prevented, either by an obftruc- tionof their orifices, or be an obftruaion of the mefenteric glands, through which alone the abforbed fluids can be tranfmitted. In one inftance of this kind, when the chyle prepared in the ftomach and duodenum is -not abforbed in the courfe of the inteftines, but paffes off in confiderable quantity by the anus, the difeafe has been named Morbus Cceliacus, or OF PHYSIC. 16f fimply and more properly Cceliaca; which accordingly I have confidered as a fpecies of diarrhoea. 1495.J I have thus endeavored to, point out the various fpecies of difeafe that may come under the general appel- lation of Diarrhoea; and from that enumeration it will ap- pear, that many, and indeed the greater part of the cafes of diarrhoea, are to be confidered as fympathetic affeaions, and to be cured only by curing the primary difeafe upon which they depend; of which, however, I cannot proper- * ly treat here. From our enumeration it will alfo appear, that many of the cafes of diarrhoea which may be confider- ed as idiopathic, will not require my faying much of them here. In many inftances, the difeafe is afcertained, and alfo the caufe affigned, by the condition of the matter eva- cuated ; fo that what is ncceffary to correa or remove it will be fufficiently obvious to petitioners of any know- ledge. In fhort, I do not find that I can offer any .general plan for the cure of diarrhoea; and all that I can pretend to do on this fubjea, is to give fome general remarks on the praaice that has been commonly followed in the cure of this difeafe. 1496. J The praaice in this difeafe has chiefly proceed- ed upon the fuppofition of an acrimony in the fluids, or m of a laxity in the fimple and moving fibres of the inteftines; v and the remedies employed have accordingly been, Cor- ^ reaors of particular acrimony, general demulcents, evacu- d» ants by vomiting or purging, aftringents, or opiates. Upon ** each of thefe kinds of remedies I fhall now offer fome re- marks. 1497.] ^n ac'd acrimony is, upon feveral occafions, the caufe of diarrhoea, particularly in children; and in fuch cafes the abforbent earths have been very properly em- ployed. The common, however, and promifcuons ufe of thefe, hath been very injudicious; and where there is any putrefcency, they muft be hurtful. 1498.] The cafes in which there is a putrid or putref- cent acrimony prevailing, have been, I think, too feldom taken notice of; and, therefore, the ufe of acids too fel- dom admitted. The acrimony to be fufpeaed in bilious cafes, is probably of the putrefcent kind. 1499.] The general correaors of acrimony are the mild diluents and demulcents. The former have not been fb l7o 'PRACTICE much employed in diarrhoea as they ought; for, joined with demulcents, they very much increafe the effe6ts of the latter : And although the demulcents, both mucilaginous and oily, may by themfelves be ufeful, yet without the af- fiftance of diluents they can hardly be introduced in fuch ■quantity as to anfwer the purpofe.* 1500.] As indigeftion and crudities prefent in the ftom- ach. are fo often the caufe of diarrhoea, vomiting muft there- fore be frequently very ufeful in this difeafe. In like manner, when the difeafe proceeds, as it often does, from obftructed perfpiration, and increafed afflux of (luids to the inteftines, vomiting is perhaps the moft effec- tual means of reftoring the determination ofthe fluids to the furface of the body. It is poffible alfo, that vomiting may give fome inverfion of the periftaltic motion, which is determined too much downwards in diarrhoea; fo that upon the whole it is a re- medy which may be very generally ufeful in this difeafe.t 1501.] Purging has been fuppofed to be more univer- fally neceffary, and has been more generally praaifed. This, however, in my opinion, proceeds upon very mif- taken notions with refpea to the difeafe; and fuch a prac- tice feems to me for the moft part fuperfluous, and in ma- ny cafes very hurtful. It goes upon the fuppofition of an acrimony prefent in the inteftines, that ought to be carried out by purging: but, if that acrimony has either been in- troduced by the mouth, or brought into the inteftines from ^ other parts ofthe body, purging can neither be a means of correcting nor of exhaufting it; and muft rather have the effea of increafing its afflux, and of aggravating its effects. From whatever fource the acrimony which can excite a harrhoea proceeds, it may be fuppofed fufficient to evacu- ate itfelf, fo far as that can be done by purging; and as # Lintfeed tea is both diluent and demulcent; but as the patient fometimes loaths it, we may in its place ufe a decoction of marih-mallow root, or of quince feed. Thefe infulions and decoctions ought to be extremely thin. An ounce of bruifed quince feed will make three pints of water as thick and ropy as the white of an egg : hence a drachm is fufficient for a pint of the decoction. Wc have another in ftaaceofa diluent and demulcent in the almond emulfion, which is an exceed- ingly elegant medicine. The formulae iu both the London and Edinburgh Pharmacopoeias are not well adapted to cafe.; of diarrhoea: for the former contains fugar, and the latter bitter almonds ; both of which ingredients increafe the irritation. In thefe cafes, therefore, an emulfion made with. fweet almonds and gum arabic, is preferable to either of the others; as, ft. Amygdal. dulc. decorticat. §i. Gum Arabic. ^\.

Wtf- *■ ———__ in cholera, fo in the fame kind of diarrhoea, it will be more proper to affift the evacuation by diluents and demulcents, than to increafe the irritation by purgatives. 1502. J If, then, the ufe of purgatives in diarrhoea may be confidered, even when an acrimony is prefent, as fuper- fluous, there are many other cafes in which it may be ex- tremely hurtful. If the irritability ofthe inteftines fhall, from affeaions in other parts of the fyftem, or other caufes, have been already very much increafed, purgatives muft neceffarily aggravate the difeafe. In the cafe of lientery, nobody thinks of giving a purgative; and in many cafes of diarrhoea approaching to that, they muft be equally im- proper. I have already obferved, that when diarrhoea pro- ceeds from an afflux of fluids to the inteftines, whether in too great quantity, or of an acrid quality, purgatives may be hurtful; and whoever, therefore, confiders the numer- ous and various fources from which acrid matter may be poured into the cavity of the inteftines, will readily per>- ceive, that in many cafes of diarrhoea, purgatives may be extremely pernicious. There is one cafe in particular to be taken notice of. When, from a general and acrid diffolution of the blood, the ferous fluids run off too copioufly in the cavity of the inteftines, and excite that diarrhoea which attends the ad- vanced ftate of heaic fever, and is properly called a. Col- liquative Diarrhoea; I have, in fuch cafes, often feen pur- gatives given with the moft baneful effeas. There is ftill another cafe of diarrhoea in which purga- tives are pernicious; and that is, when the difeafe depends, as we have alleged it fometimes may, upon an erythema- tic inflammation of the inteftines. I need hardly add, that if there be a cafe of diarrhoea depending upon a laxity of the folids, purgative^ cannot there be of any fervice, and may do much harm. Upon the whole, it will, I think, appear, that the ufe of purga- tives in diarrhoea is very much limited; and that the pro- miscuous ufe of them, which has been fo common, is in- judicious, and often pernicious. I believe the praaice has been chiefly owing to the ufe of purgatives in dyfente- ric cafes, in which they are truly ufeful; becaufe, con- . i72 PRACTICE trary to the cafe of diarrhoea, there is iii dyfentery a con- fiderable conftriaion of the inteftines.* 1503. J Another fet of remedies employed in diarrhoea are aftringents. There has been fome hefitation about the employment of thefe in recent cafes, upon the fuppofition that thev might occafion the retention of an acrid matter that fhould be thrown out. I cannot, however, well un- dcrftand or affign the cafes in which fuch caution is necef- fary ; and I think that the power of aftringents is feldom fb great as to render their ufe very dangerous. The only difficulty which has*occurred to me, with ref- pea to their ufe, has been to judge of the circumftances to which they are efpecially adapted. It appears to me to be only in thofe where the irritability of the inteftines de- pends upon a lofs of tone : And this, I think, may occur from the debility ofthe whole fyftem, or from caufes aa- ing on the inteftines alone. All violent or long continued fpafmodic and convulfive affeaions of the inteftinal canal neceffarily irwtoce a debility there; and fuch caufes often take place, from violent irritation, in colic, dyfentery, cholera, and diarrhoea.f 1504.] The laft of the remedies of diarrhoea that re- main to be mentioned are opiates. The fame objeaions have been made to the ufe of thefe, in recent cafes of diar- rhoea, as to that of aftringents; but on no good grounds: For the effea of opiates, as aftringent, is never very per- manent ; and an evacuation depending upon irritation, * Notwithftanding-all the author advances concerning the danger of purgatives fn » diarrhoea, there are fome cafes in which they are of lingular utility. His arguments in this article »re doubtlef* juft; and, in the fpecies of diarrhoea which he here enumerates, purgatives are certainly hurtful' but many inltancc* of diarrhoea occur, which proceed from an acrimony that is extremely tenacious, and that adheres clofay to the Internal furface of the inteltines, or is retained in their folds, rh fuch- cafes, purgatives are tfeonly remedies for removing the difeafe, and ought therefore to be ufed. In all otlier cafes'? as the .juthor juftly obferves, they are certainly pernicious. Having afcertained ivhen purgatives are pro^T, the next confideration is, -what purgatives ought to be ufed .' The anfwer is Ctivious:—Neutral falts, particularly Soda phofpliorata, Rochal fait, Glauber's falts, and Eplom fait, which are enumerated in the order of their being agreeable, but in a contrary order to their decree pfefficacy; 4fce Epfom fait being the leaft agreeable, but the moft efficacious. i The aftringents to be ufed, when they are proper, are various: as Alum, Logwood, Catechu. Rhubarb, St. The author juftly remarks, that aftringents are only ufeful in cafes of debility, and therefore the tonic aftringents are undoubtedlv preferable to any other. Rhubarb and Peruvian hark, each poueffing both thefe qualities, may therefore be advaniageoufly ufed conjointly, as in the following formula: R. Pulv. Cort. Peruv. .^i. Rad. Rhei, 3 ft. M. f. Pulv. The dofe of this powder may be varied according to circumftances, from a fcruple to a drachm, .twice a day, witha glafs of Port wine after it. It may not be improper to obferve,'that in diarrhoea* in general, peculiar attention muft be paid to diet. The oleraceous and acefcent vegetables muft be carefully avoided; a* muft alio all fermented liquors except Port wine: of the farinaceous vege- tables, rice is the beft; and rice-water, with a little cinnamon and Port wine, is the moft proper ilrink for patient* in thefe cafes. Roafted meats are preferable to boiled: and veal, lamb, or chickens,. preferable to beef or mutton. Perk is very improper 1 as are alfo all kinds of filh. Puddings of all kinds without fruit are very proper food for fuch patients, efpecially rice-puddings made without e££s., but with milk and cinnamon ; and alfo rice-milk, fago with Tort wine, blancnunije. &x. OF PHYSIC. 174 - though it may be for fome time fufpcnded by opiates, yet always returns very foon. It is only by taking off irrita- bility that opiates are ufeful in diarrhoea; and therefore, when the difeafe depends upon an increafe of irritability alone, or when, though proceeding from irritation, that irritation is correaed or exhaufted, opiates are the moft ufeful and certain remedy. And though opiates are not fuited to correa or remove an irritation applied, they are often of great benefit in fufpending the effeas of that irri- tation whenever thefe are violent: And, upon the whole, it will appear, that opiates may be very frequently, and with great propriety, employed in the cure of diarrhoea. CHAP. XII. ©f tfte Diabetes, 1505.] 1 HIS difeafe confifts in the voiding of an unu- fually large quantity of urine. *> As hardly any fecretion can be increaferTwithout an in- creafed aaion of the veffels concerned in it, and as fome inftances of this difeafe are attended with affeaions ma- nifeftly fpafmodic, I have had no doubt of arranging the diabetes under the order of Spafmi. 1506. J This difeafe is always accompanied with a great degree of thirft, and therefore with the taking in of a great quantity of drink. This in fome meafure accounts for the very extraordinary quantities of urine voided: But ftill, independent of this, a peculiar difeafe certainly takes place; as the quantity of urine voided does almoft always exceed the whole of the liquids, and fometimes the whole • of both folids and liquids, taken in. I 1507.] The urine voided in this difeafe is always very \ clear, and at firft fight appears entirely without any color; ; but viewed in a. certain light, it generally appears to be flightly tinged with a yellowifh green, and m this refpea has been very properly compared to a folution of honey in a large proportion of water. Examined by the tafte, it is very generally found to be more or lefs fweet; and many experiments thaehave now been made in different inftances of the difeafe fhow clearly Vol. II. Y 174 PRACTICE that fuch urine contains, in confiderable quantity, a fac- charine matter which appears to be very exaaiy of the na- ture of common fugar. 1508.] Doaor Willis feems to me to have been the fit ft who took notice of the fweetnefs of the urine in diabetes, and almoft every phyfician of England has fince taken no- tice of the fame. It is to be doubted, indeed, if there is any cafe of idiopathic diabetes in which the urine is of a different kind. Though neither the ancients, nor, in the other countries of Europe, the moderns, till the latter were direaed to it by the Englifh, have taken notice of the fweetnefs of the urine, it does not perfuade me, that either in ancient or in modern times the urine in diabetes was of another kind. I myfelf, indeed, think I have met with one inftance of diabetes in which the urine was perfectly infipid; and it would feem that a like obfervation had oc- curred to Dr. Martin Lifter. I am perfuaded, however, that fuch inftances are very rare; and that the other is by much the more^common, and perhaps the almoft univerfal occurrence. I judge, therefore, that the prefence of fuch a faccharine matter may be confidered as the principal cir- cumftance in idiopathic diabetes; and it gives at leaft the only cafe of that difeafe that I can properly treat of here, for I am only certain that what I am further to mention re- lates to fuch a cafe. 1509.] The antecedents of this difeafe, and confequent- ly the remote caufes of it, have not been well afcertained. It may be true that it frequently happens to men who, for a long time before, had been intemperate in drinking; that it happens to perfons of a broken conftitution, or who, as we often exprefs it, are in a cacheaic ftate; that it fome- times follows intermittent fevers; and that it has often oc- curred Jrom excefs in drinking of mineral waters. But none of thefe caufes apply very generally to the cafes that occur: Such cafes are not always, nor even frequently, followed by a diabetes; and there are many inftances of diabetes which could not be referred to any of them. In moft of the cafes of this difeafe which I have met with, I could not refer it to any particular caufe. 1510.] This difeafe commonly comes on flowly, and almoft imperceptibly, without an^ previous diforder. it often arifes to a confiderable degree, and fubfifts long with- 0 F PHYSIC. 1^5 out being accompanied with evident diforder in any parti- cular part of the fyftem. The great thirft which always, and the voracious appetite which frequently, occur in it, are often the only remarkable fymptoms. Under the con- tinuance of the difeafe, the body is often greatly emaciated; and a great wreakncfs alfo prevails. The pulfe is common- ly frequent; and an obfcure fever is for the moft part pre- fent. When the difeafe proves fatal, it generally ends with a fever, in many circumftances, particularly thofe of emaciation and debility, refembling a heaic. 1511.] The proximate caufe of this difeafe is not cer- tainly or clearly known. It feems to have been fometimes conneaed with calculous affe6tions of the kidneys; and it is poffible, that an irritation applied there may increafe the fecretion of urine. It perhaps often does fo; but how it fhould produce the finguiar change that takes place in the ftate of the urine, is not to be eafily explained. It certain- ly often happens, that calculous matters are long prefent in the urinary paffages, without having any fuch effea as that of producing diabetes in any fhape. Some have fuppofed that the difeafe occurs from a relax- ed ftate of the fecretory veflels of the kidneys; and indeed the diffeaions of perfons who had died of this difeafe have fhown the kidneys in a very flaccid ftate. This however, is probably to be confidered as rather the effea than the caufe of the difeafe. That no topical affeaion of the kidneys has a fhare in producing this difeafe, and that a fault in the affimilation of the fluids is rather to be blamed, I conclude from hence, that even the folid food taken in, increafes the quantity of the urine voided, at the fame time with an increafe of the faccharine matter above-mentioned. 1512.] The diabetes has been fuppofed to be o#ing to a certain ftate of the bile: and it is true, that this difeafe has fometimes occurred in perfons who were at the fame time affeaed with difeafes of the liver: But this occurrence does not often take place; and the diabetes frequently occurs feparately from any affeaion of the liver. In twenty in- ftances of diabetes which I have feenj there was not in any one of them any evident affection of the liver. The explanation that has been offered of the nature and 176 PRACTICE operation of the bile, in producing diabetes is very hypo- thetical, and no wife fatisfying. 1513.] As I have already faid, I think it probable, that fn molt cafes the proximate caufe of this difeafe is fome fault in the aflimilatory powers, or in thofe employed in converting alimentary matters into the proper animal fluids. This I formerly hinted to Dr. Dobfon, and it has been pro- fecuted and publifhed by him; but I muft own that it is a theory embarraffed with fome difficulties which I cannot at prefent very well remove. 1514.] The proximate caufe of diabetes being fo little known or afcertained, I cannot propofe any rational me- thod of cure in the difeafe.* From the teftimony of feveral authors, I believe that the difeafe has been cured: but I believe alfo, that this has feldom happened; and when the difeafe has been cured, I doubt much if it was effefcted by the feveral remedies to which thefe cures have been afcribed. In all the inftances of this difeafe which I my felf have feen, and in feveral others of which I have been informed, no cure of it has ever been made in Scotland, though many in- ftances of it have occurred, and in moft of them the reme- dies recommended by authors have been diligently employ- ed. I cannot, therefore, with any advantage, enter into a detail of thefe remedies; and as the difeafe, together with its feveral circumftances, when they fliall hereafter occur, is likely to become the fubjea of diligent invettigation, I avoid going farther at prefent, and judge it prudent to fuf- pend my opinion till I fhall have more obfervations and experiments upon which I can form it more clearly. CHAP. XIII. ©f «tfje listeria, or tfje 5>p$teric iDisease. 1515.] i HE many and various fymptoms which have been fuppofed to belong to a difeafe under this appellati- on, render it extremely difficult to give a general charaaer * The difeafe !s l.app'.ly not very common: but, when a phyfician is called, he is under the neceffity of doing fomething, and not remaining inaftive. Some general directions mav therefore be ac- ceptable to the yoiing practitioner. The cure will principally confift in avoiding whatever mav relax the renal vellels, efpecially bv avoiding ftrong drink. As the quantity of urine is always lefs in pro- portion as the perfpiration u increafed, it feems advifeable to keep the furface of the Ikin lax and perfpirable ; and, if the patient's ftrength allows him, he ought frequently to ufe bodily exercife to promote fweat. For a fimilar reafon, external cold muft be avoided, becaufe by diminifhing perfpi- ntion, a larger quantity of fluids is derived to the kidneys. In fome cafes the difeafe may be pro- bably owing to a lax or weak itate of the kidneys: hence the indication of tonics, as Peruvian bark, ar d other tonic bitters. ut ij ri i S I C. 177 or definition of it. It is, however, proper in all cafes to attempt fome general idea; and therefore, by taking the moft common form, and that concurrence of fymptoms by which it is principally diftinguifhed, I have formed a character in my fyftem of Methodical Nofology, and fhall here endeavour to illustrate it by giving a more full hiftory of the phenomena. 1516. J The difeafe attacks in paroxyfms or fits. Thefe commonly begin by fome pain and fulnefs felt in the left fide of the belly. From this a ball* feems to move with a grumbling noife into the other parts of the belly; and, making as it were various convolutions there, feems to O .... move into the ftomach; and more diftinctly ftill riles up to the top of the gullet, where it remains for fome time and by its preffure upon the larynx gives a fenfe of fuffocation. By the time that the difeafe has proceeded thus far, the patient is affeaed with a ftupor and infenfibility, while at the fame time the body is agitated with various convulfi- ons. The trunk of the body is wreathed to and fro, and the limbs are varioufly agitated; commonly the convulfive motion of one arm and hand, is that of beating with the doled fift, upon the breaft very violently and repeatedly. This ftate continues for fome time, and has during that time fome remiffions and renewals of the convulfive mo- tions; but they at length ceafe, leaving the patient in a ftu- pid and feemingly fleeping ftate. More or lefs fuddenly, and frequently with repeated fighing and fobbing, toge- ther with a murmuring noife in the belly, the patient re- turns to the exercife of fenfe and motion, but generally without any recolleaion of the feveral circumftances that »iad taken place during the fit. 1517.] This is the form of what is called an hysteric paroxysm, and is the moft common form; but its parox- yfms are confiderably varied in different perfons, and even in the fame perfon at different times. It differs, by hav- inn more or fewer ofthe circumftances above-mentioned; by thefe circumftances being more or lefs violent; and by the different duration ofthe whole fit. Before the fit there is fometimes a fudden and unufually large flow of limpid urine. At the coming on of the fit, the ftomach is fometimes affeaed with vomiting, the lungs # Commonly called Globus liysltritus by authors. 178 PRACTICE with confiderable difficulty of breathing, and the heart with palpitations. During the fit, the whole of the belly, and particularly the navel, is drawn ftrongly inwards; the fpincter and ani is fometimes fo firmly conltriaed as not to admit a fmall glyfter-pipe, and there is at the fame time an entire fuppreffion of urine. Such fits are, from time to time, ready to recur; and during the intervals, the pa- tients are liable to involuntary motions, to fits of laughing and crying, with fudden tranfition from the one to the o- ther; while fometimes falfe imaginations, and fome degree of delirium, alfo occur. 1518.] Thefe affeaions have been fuppofed peculiar to the female fex ; and indeed they moft commonly appear in females: but they fometimes, though rarely, attack the male fex; never, however, that I have obferved, in the fame exquifite degree. In the female fex, the difeafe occurs efpecially from the age of puberty to that of thirty-five years; and though it does fometimes, yet very feldom appears before the former or after the latter of thefe periods. At all ages, the time at which it moft readily occurs is that of the menftrual period. The difeafe more efpecially affects the females of the moft exquifitely fanguine and plethoric habits, and frequently af- feas thofe of the moft robuft and mafculine conftitutions. It affeas the barren more than breeding women, and therefore frequently young widows. It occurs efpecially in thofe females who arc liable to the Nymphomania; and the Nofologifts have properly enough marked one of the varieties of this difeafe by the title of Hysteria Libidinosa. In the perfons liable to the fits of this difeafe, it is rea- dily excited by the paffions of the mind, and by every con- fiderable emotion, efpecially thofe brought on by furprife. The perfons liable to this difeafe acquire often fuch a degree of fenfibility, as to be ftrongly affeaed by every impreffion that comes upon them by furprife. 1519. J In this hiftory, there appears to be a concurrence o^ fymptoms and circumftances properly marking a very particular difeale, which I think may be diftinguifhed from all others. It feems to me to have been improperly confi- dered by phyficians as the fame with fome other difeafes3 OF PHYSIC. 179 and particularly with hypochondriafis. The two difeafes may have fome fymptoms in common, but for the moft part are confiderably different. Spafmodic affeaions occur in both difeafes; but neither fo frequently nor to fo great a degree, in hypochondriafis as in hylteria. Perfons liable to hyfteria are fometimes affeaed at the fame time with dyfpepfia. They are often, however, en- tirely free from it; but I believe this never happens to per- fons affeaed with hypochondriafis. Thefe different circumftances mark fome difference in the two difeafes; but they are ftill more certainly diftinguifhed by the temperament* they attack, and by the timet of life at which they appear to be moft exquifitely formed. It has been generally fuppofed, that the two difeafes dif- fer only in refpea of their appearing in different fexes. But this is not well founded: For although the hyfteria ap- pears moft commonly in females, the male fex is not abfo- lutely free from it, as I have obferved above; and although the hypochondriafis may be moft frequently in men, the inftances of it in the female fex are very common.^ 1520.] From all thefe confiderations, it muft, I think, appear, that the hyfteria may be very well, and properly, diftinguifhed from hypochondriafis. Further, it feems to me to have been with great impro- priety, that almoft every degree of the irregular motions of the nervous fyftem has been referred to the one or other of thefe two difeafes. Both are marked by a peculiarity of temperament, as well as by certain fymptoms commonly accompanying that; but fome of thefe, and many others ufually marked by the name of nervous fymptoms may, from various caufes, arife in temperament different from that which is peculiar to either hyfteria or hypochondriafis, and without being joined with the peculiar fymptoms of ei- ther the one or the other difeafe: So that the appellations of Hyfteric and Hypochondriac are very inaccurately ap- plied to them. Under what view thefe fymptoms are other- wife to be confidered, I am not ready to determine; but muft remark, that the appellation of Nervous Difeafes is too vague and undefined to be of any ufeful application. * Hyfteria attacks the fanguine and plethoric, but Hypochondriafis the melancholic. t Hypochondriafis fcarcely ever appears early in life, nor Hylteria late : and Hypochondriafis be- comes aggravated, but Hylteria relieved by advancing age. J I'he Hypochondriafis in women hat been frequently miftaken for Hyfteria. 1*0 PRACTICE 1521.J Having thus endeavored to diftinguifh hyfteria from every other difeafe, I fliall.now attempt its peculiar pathology. With refpea to this, I think it will, in the firft place, be obvious, that its paroxyfms begin by a convulfive and fpafmodic affeaion ofthe alimentary canal, which is af- terwards communicated to the brain, and to a great part of the nervous fyftem. Although the difeafe appears to be- gin in the alimentary canal, yet the connection which the paroxyfms fo often have with the menftrual flux, and with the difeafes that depend on the ftate of the genitals, fhows, that the phyficians have at all times judged rightly in con- fidering this difeafe as an affeaion of the uterus and other parts ofthe genital fyftem. 1522.J With regard to this, however, I can go no farther. In what manner the uterus, and in particular the ovaria, are affected in this difeafe; how the affection of thefe is commu- nicated, with particular circumftances, to the alimentary canal; or how the affeaion of this, riling upwards, affctts the brain, fo as to occafion the particular convulfions which occur in this difeafe, I cannot pretend to explain. But although I cannot trace this difeafe to its firft caufes, or explain the whole of the phenomena, I hope, that with refpect to the general nature ofthe difeafe, I may form fome general conclufions, which may ferve to direa our condua in the cure of it. 1523.J Thus, from a confideration ofthe predifponent and occafional caufes, it will, I think, appear, that the chief part of the proximate caufe is a mobility of the fyftem, de- pending generally upon its plethoric ftate. 1524.J Whether this difeafe ever arifes from a mobility ofthe fyftem, independent of any plethoric ftate of it, I cannot pofitivcly determine; but in many cafes that have fubfifted for fome time, it is evident that a fenfibility, and confequently a mobility, are acquired, which often appear when neither a general plethora can be fuppofed to fubfiit,. nor an occafional turgefcence to have happened. How- ever, as we have fhown above, that a diftention of the vef- fels ofthe brain feems to occafion epilepfy, and that a tur- gefcence of the blood in the veffels of the lungs feems to produce afthma; fo analogy leads me to fuppofe, that a turgefcence of blood in the uterus, or in other parts of the genital fyftem, may occafion the fpafmodic and convulfive OF PHYSIC. 181' motions which appear in hyfteria. It will, at the fame time, be evident, that this affeaion ofthe genitals muft ef- pecially occur in plethoric habits ; and every circumftance mentioned in the hiftory of the difeafe ferves to confirm this opinion with refpect to its proximate caufe. 1525.] From this view ofthe fubjea, the analogy of hyf- teria and epilepfy will readily appear ; and why, therefore, I am to fay that the indications of cure are the fame in both. As the indications, fo the feveral means of anfwering them are fo much the fame in both difeafes, that the fame obfervations and direaions, with regard to the choice and employment of thefe remedies, that have been delivered above on the fubjea of epilepfy, will apply pretty exaaiy to hyfteria; and therefore need not to be repeated here.* CHAP.

The dofe of it is 30 or 40 drops repeated occafionally.—The Tinftura Valerianae volatilis of both the Pharmacopxias is alfc frequently ufed. Its dofe is a tea-fpoonful or two.—Few of the compolitions of the (hops are found tobe more efficacious antifpafmodics, than the Spiritus jttheris Vitriollcus compofitus of the London Pharmacopoeia.

Thefe and other antifp ifmodics may be ufed promifruoufly ; for in different cafes and conftitutior.j, they prove differ- ently oificacin'ii. Sometimes they may be varioufly combined with one another, and with opium.

I 18£ PRACTICE fatisfying to my felf, or that I can expeatoprovefoto others. I find alfo, with refpea to the cure of this difeafe, that there is no fubjea in which the fallacy of experience appears more ftrongly than in this. From the moft ancient to the prefent times, many remedies for preventing and curing this difeafe have been recommended under the fane!ion of pretended experience, and have perhaps alfo kept their cre- dit for fome time: but fucceeding times have generally, upon the fame ground of experience, deftroyed that credit entirely; and moft of the remedies formerly employed are now fallen into abfolute neglea. In the prefent age, fome new remedies have been propofed, and have experience al- ledged to vouch for their efficacy; but many doubts ftill remain with refpea to this: and though I cannot determine in this matter from my own experience, I think it incum- bent on me to give the beft. judgment I can form with ref- pea to the choice of the remedies at prefent recommended. 1527.] I am in the firft place, firmly perfuaded, that the moft certain means of preventing the confequences of the bite, is to cut out, or otherwife deftroy, the part in which the bite has been made. In this every body agrees; but with this difference, that fome are of opinion that it can only be effeaual when it is done very foon after the wound has been made, and they therefore neglea it when this opportunity is miffed. There have been, however, no experiments made proper to determine this matter: and there are many confiderations which lead me to think, that the poifon is not immediately communicated to the fyftem j and therefore, that this meafure of deftroying the part may be praaifed with advantage, even many days after the bite has been given. 1528.] Whilft the ftate of our experience, with refpea to feveral remedies now in ufe, is uncertain, I cannot ven- ture to affert that any of thefe is abfolutely ineffeaual; but I can give it as my opinion, that the efficacy of mer- cury, given very largely, and perfifted in for a long time, both as a means of preventing the difeafe, and of curing it when it has aaually come on, is better fupported by ex- perience than that of any other remedy now propofed or commonly employed. ,83 BOOK IV. Of Vesania:, or Disorders ofthe Intellectual Functions, CHAP. I. £)f £Je#aniac in general* J529 ] X HE Nofologifts, Sauvages and Sagar, in a clafs of difeafes under the title of Vesania, have comprehend- ed the two orders, of Hallucinationes or Falfe Perceptions, and of Morositates or Erroneous Appetites and Paffions; and, in like manner, Linnaeus in his clafs of Men tales, correfponding to the Vefanice of Sauvages, has compre- hended the two orders of Imaginarii and Pathetici, nearly the fame with the Hallucinationes and Morositates of that author. This, however, from feveral confiderations, ap- pears to me improper ; and I have therefore formed a clafs of Vefanice nearly the fame with the Paranoias of Vogel, excluding from it the Hallucinationes and Morofitates, which I have referred to the Morbi Locales. Mr. Vogel has done the like, in feparating from the Paranoial the falfe perceptions and erroneous appetites; and has thrown thefe into another clafs, to which he has given the tide of Hype- raefthefes. 1530.] It is indeed true, that certain hallucinationes and morofitates are frequently combined with what I pro- pofe to confider as ftriaiy a vefania or an erroneous judg- ment; and fometimes the hallucinationes feem to lay the foundation of, and to form almoft entirely, the vefania. But as moft part of the hallucinationes enumerated by the Nofologifts are affeaions purely topical, and induce no other error of judgment befide that which relates to the fingle objea of the fenfe or particular organ affeaed ; fo thefe arc certainly to be feparated from the difeafes which confift in a more general affeaion of the judgment. Even, when the hallucinationes conftantly accompany or feem to induce the vefania, yet being fuch as arife from internal caufes, and may be prefumed to arife from the fame caufe as the more general affeaion of the judgment, they are therefore to be confidered as fymptoms of this only. In like manner I judge with refpea to the morofitates, or erroneous paffions; that accompany vefania; which, as 184 PRACTICE confequences of a falfe judgment, muft be confidered as arifing from the fame caufes, and as fymptoms only, of the more general affection. There is, indeed, one cafe of a morofitas which feems to induce a vefania, or more general affedion of the judg- ment; and this may lead us to confider the vefania, in this cafe, as a fymptom of an erroneous appetite, but will not afford any good reafon for comprehending the morofitates in general under the vefania?, confidered as primary difeafes. The limitation, therefore, of the clafs of Vefaniae to the lefions of our judging faculty, feems from every confider- ation to be proper. The particular difeafes to be comprehended under this clafs, may be diftinguifhed according as they affia perfons in the time of waking or fleeping. Thofe which affea men awake, may again be confidered, as they confift in an erroneous judgment, to which I fhall give the appellation of Deliriums or as they confift in a weaknefs or imperfec- tion of judgment, which I fhall name Fatuity. I begin with the confideration of Delirium. 1531-] As men differ greatly in the foundnefs and force of their judgment, fo it may be proper here to afcertain more precifely what error or imperfeaion of our judging faculty is to be confidered as morbid, and to admit of the appellations of Delirium and Fatuity. In doing this, I fhall firft confider the morbid errors of judgment under the general appellation of Delirium, which has been com- monly employed to denote every mode of fuch error. 1532.] As our judgment is chiefly exercifed in difcern- ing and judging of the feveral relations of things, I appre- hend that'delirium may be defined to be,—In a perfon a- wake, a falfe or miftaken judgment of thofe relations of things, which, as occurring moft frequently in life, are thofe about which the generality of men form the fame judgment; and particularly when the judgment is very different from what the perfon himfelf had before ufually formed. 1533. J With this miftaken judgment of relations there is frequently joined fome falfe perception of external ob- jeas, without any evident fault in the organs of fenfe, and which feems therefore to depend upon an internal caufe; that is, upon the imagination arifing from a condition in U£ PH'xSie. 185 the brain prefenting objeas which are not aftually prefent. Such falfe perceptions muft neceffarily occafion a delirium, or an erroneous judgment, which is to be confidered as the difeafe. 1534-] Another circumftance, commonly attending de- lirium, is a very unufual afibciation of ideas. As, with refpea to moft of the affairs of common life, the ideas laid up in the memory are, in moft men, affociated in the fame manner; fo a very unufual affociation, in any individual, muft prevent his forming the ordinary judgment of thofe relations which are the moft common foundation of afib- ciation in the memory: And therefore this unufual and commonly hurried afibciation of ideas, ulually is, and may be confidered as, a part of delirium. In particular, it may be confidered as a certain mark of a general morbid affec- tion of the intelleaual organs, it being an interruption or perverfion of the ordinary operations of memory, the com- mon and neceffary foundation of the exercife of judgment. 1535-J A third circumftance attending delirium, is an emotion or paflion, fometimes of the angry, fometimes of the timid kind; from whatever caufe in the perception or judgment, it is proportioned to fuch caufe, either in the manner formerly cuftomary to the perfon himfelf, or in the manner ufual with the generality of other men. 1536.] Delirium, then, may be more fhortly defined— In a perfon awake, a falfe judgment arifing from percep- tions of imagination, or from falfe recolleaion, and com- monly producing difproportionate emotions. Such delirium is of two kinds; as it is combined with pyrexia and comatofe affeaions: or, as it is entirely without any fuch combination. It is the latter cafe that we name Insanity ; and it is this kind of delirium only that I am to treat of here. 1537.] Infanity may perhaps be properly confidered as a genus comprehending many different fpecies, each of which may deferve our attention; but before proceeding to the confideration of particular fpecies, I think it proper to at- tempt an inveftigation ofthe caufe of infanity in general. 1538.] In doing this, I fhall take it for granted, as de- monftrated elfewhere, that although this difeafe feems to be chiefly, and fometimes folely, an affeaion of the mind; yet the conneaion between the mind and body in this cafe 186 PRACTICE is fuch, that thefe affedions of tjie mind muft be confider- ed as depending upon a certain ftate of our corporeal part. See Halleri Prim. Lin. Phyfio. log. $ 570. See Bocr- haavii Inft. Med. $ 581. 696. 1539.] Admitting this propofition, I muft in the next pla.ce affume another, which 'I likewife fuppofe to be de- monftrated elfewhere. This is, that the part of our body more immediately conneaed with the mind, and therefore more efpecially concerned in every affeaion of the intel- , le&ual funaions, is the common origin of the nerves; which I fhall, in what follows, fpeak of under the appellation of the Brain. 1540.] Here, however, in affuming this laft propofition, a very great difficulty immediately prefents itfelf. Altha' we cannot doubt that the operations of our intelka always depend upon certain motions taking place in the brain, (fee Gaub. Path. Med. J 523;) yet thefe motions have never . been the objeas of our fenfes, nor have we been able to perceive that any particular part ofthe brain has more con- cern in the operations of our intellea than any other. Nei- ther have we attained any knowledge of what fhare the fe- veral parts ofthe brain have in that operation; and there- fore, in this fituation of our fcience, it muft be a very diffi- cult matter to difcover thofe ftates of the brain that may give occasion to the various ftate of our intelleaual funaions. '1541.] It may be obferved, that the different ftate of the motion of the blood in the veflels of the brain has fome fhare in affeaing the operations ofthe intellea*. and phy- ficians, in feeking for the caufes of the different ftates of our intelleaual funaions, have hardly looked further than into the ftate of the blood, or into the condition of the blood itfelf: but it is evident that the operations of the intellec- tual funaions ordinarily go on, and are often confiderably varied, without our being able to perceive any difference either in the motions or in the condition of the blood. 1542. J Upon the other hand, it is very probable that the ftate of the intelleaual funaions depends chiefly upon the ftate and condition of what is termed the Nervous Power, or, as we fuppofe, ofa fubtile very moveable fluid, includ- ed or inherent, in a manner we do not clearly underftand in every part ofthe medullary fubftance ofthe brain and nerves, and which in a living and heajthy man is capable OF PHYSIC. W of being moved from every one part to every other of the nervous fyftem. 1543-] With refpea to this power, we have pretty clear proof that it frequently has a motion from the fentient ex- tremities of the nerves towards the brain, and thereby pro- duces fenfation; and we have the fame proof, that in con- fequence of volition the nervous power has a motion from the brain into the mufcles or organs of motion. Accord- ingly, as fenfation excites our intelle£tual operations, and volition is the effea of thefe, and as the conneaion between fenfation and volition is always by the intervention of the brain and of intelleaual operations; fo we can hardly doubt, that thefe latter depend upon certain motions, and the various modification of thefe motions, in the brain. 1544-J To afcertain the different ftates of thefe motions may be very difficult; and phyficians have commonly con- fidered it to be fo very myfterious, that they have general- ly defpaired of attaining any knowledge with regard to it: But I confider fuch abfolute defpair, and the negligence it infpircs, to be always very blameable; and I fhall now venture to go fome length in the inquiry, hoping that fome fteps made with tolerable firmnefs may enable us to go ftill further. 1545«J To this purpofe, I think it evident, that the ner- vous power, in the whole as well as in the feveral parts of the nervous fyftem, and particularly in the brain, is at dif- ferent times in different degrees of mobility and force. To thefe different ftates, I beg leave to apply the terms of Excitement and Collapse. To that ftate in which the mo- bility and force are fufficient for the exercife of the func- tions, or when thefe ftates are any way preternaturally in- creafed, I give the name of Excitement; and to that ftate in which the mobility and force are not fufficient for the ordinary exercife of the funaions, or when they are dimi- nifhed from the ftate in which they had been before, I give the name of Collapse. I beg, however, it may be ob- ferved, that by thefe terms I mean to exprefs matters o£ faa only; and without intending, by thefe terms, to ex- plain the circumftance or condition, mechanical or phyfi- cal, of the nervous power or fluid in thefe differ«ht ftates. i 546.] That thefe different ftates of excitement and col- lapfe take place on different occafions, muft, I think, be 188 PRACTICE manifeft from numberlefs phenomena of the animal eco- nomy : But it is efpecially to our prefent purpofe to ob- ferve, that the different ftates of excitement and collapfe, are in no inftance more remarkable, than in the different ftates of waking and fleeping. In the latter, when quite complete, the motion and mobility of the nervous power, with refpea to the whole of what are called the Animal Funaions, entirely ceafe, or, as I would exprefs it, are in a ftate of collapfe; and are very different from the ftate of waking, which in healthy perfons I would call a ftate of general and entire excitement. 1547.] This difference in the ftates of the nervous pow- er in fleeping or waking being admitted, I muft in the next place obferve, that when thefe ftates are changed from the one into the other, as commonly happens every day, the change is hardly ever made inftantaneoufly, but almoft always by degrees, and in- fome length of time only: And this may be obferved with refpea to both fenfe and moti- on. Thus when a perfon is falling afleep, the fenfibility is gradually diminifhed : So that, although fome degree of fleep has come on, flight impreffions will excite fenfation, and bring back excitement; which the fame, or even ftron- ger impreffions, will be infufficient to produce when the ftate of fleep has continued longer, and is, as we may fay, more complete. In like manner, the power of voluntary motion is gradually diminifhed. In fome members it fails fooner than in others; and it is fome time before it be- ' comes general and confiderable over the whole. The fame gradual progrefs may be remarked in a per- fon's coming out of fleep: The ears in this cafe are often awake before the eyes are opened or fee clearly, and the fenfes are often awake before the power of voluntary motion is recovered; and it is curious to obferve, that, in fome cafes, fenfations may be excited without producing the or- dinary affociation of ideas. See Mem. de Berlin, 1752. 1548.] From all this, I think it will clearly appear, that not only the different ftates of excitement and collapfe can take place in different degrees, but that they can take place in different parts of the brain, or at leaft, with refpect to the differentA^inaions, in different degrees. As I prefume that almoft every perfon has perceived the gradual approach of fleeping and waking, I likewife fup- OF PHYSIC. 189 pofe every perfon has obferved, that, in fuch intermediate ftate of unequal excitement, there almoft always occurs more or lefs of delirium, or dreaming, if any body choofes to call it fo. There are in this ftate falfe perceptions', falfe affociations, falfe judgments, and difproportionate emo- tions; in fhort, all the circumftances by which I have above defined delirium. This clearly fhows that delirium may depend, and I fhall hereafter endeavor to prove that it commonly does depend upon fome inequality in the excitement of the brain; and that both thefe affertions are founded on this, that, in order to the proper exercife of our intelleaual fanaions, the ex- citement muft be complete, and equal in every part of the brain. For though we cannot fay that the veftiges of ideas are laid up in different parts ofthe brain, or that they are in fome meafure diffufed over the whole, it will follow upon either fuppofition, that as our reafoning and our intelleaual operations always require the orderly and exaa recolleaion or memory of affociated ideas; fo, if any part of the brain is not excited, or not excitable, that recolleaion cannot pro- perly take place, while at the fame time other parts of the brain, more excited and excitable, may give falfe percep- tions, affociations, and judgments. 1549.] It will ferve to illuftrate this, that the collapfe in fleep is more or lefs complete; or that the fleep, as we com- monly fpeak, is more or lefs profound; and therefore, that in many'cafes, though fleep takes place to a confiderable de- gree, yet certain impreffions do ftill take effea, and excite motions, or, if you will, fenfations in the brain; but which fenfations, upon account of the collapfed ftate of fo great a part of the brain, are generally of the delirious kind, or dreams, confifting of falfe perceptions, affociations, and judgments, that would have been corrected if the brain had been entirely excited. Eve*ry one, I believe, has obferved, that the moft im- perfea fleeps, are thofe chiefly attended with dreaming; that dreams, therefore, moft commonly occur towards morning, when the complete ftate of fleep is pafling away; and further, that dreams are moft commonly excited by ftrong and uneafy impreffions made upon the body. I apprehend it may alfo be an illuftration of the fame V'JL. II. A A Bo PRACTICE thing, that, even in waking hours, we have an inftance of an unequal ftate of excitement in the brain producing deli- rium. Such, I think, occurs in the cafe of fever. In this it is manifeft, that the energy of the brain, or its excite- ment, is confiderably diminifhed with refpeci to the animal funaions: and it is accordingly upon this ground that 1 have explained above, in (45.) the delirium which fo com- monly attends fever. To what I have there faid I fhail here only add, that it may ferve to confirm my doarine, that thedelirium in fever comes onat a certain period ofthe difeafe only, and that we can commonly difcernits approach by a more than ufual degree of it appearing in the time of the patient's falling into or coming out of fleep. It appears, therefore, that delirium, when it firft comes on in fever, depends upon an inequality of excitement; and it can hard- ly be doubted, that the delirium which comes at length to prevail in the entirely weakened ftate of fevers, depends upon the fame caufe prevailing in a more confiderable degree. 1550.J From what has been now delivered, I hope it will be fufficiently evident, that delirium may be, and fre- quently is, occafioned by an inequality in the excitement. ofthe brain. How the different portions of the brain may at the fame time be excited or collapfed in different degrees, or how the energy of the brain may be in different degrees of force, with refpea to the feveral animal, vital, and natural func- tions, I cannot pretend to explain; but it is fufficiently evident in faa, that the brain may be at one and the fame time in different conditions with refpea to thefe functions. Thus in inflammatory difeafes, when by a ftimulus applied to the brain the force of the vital funaions is preternatural- ly increafed, that of the animal is either little changed, or confiderably diminifhed. On the contrary, in many cafes of mania, the force of the animal fun6tions depending al- ways on the brain, is prodigioufly increafed, while the ftate ofthe vital funaion in the heart is very little or not at all changed. I muft therefore fay again, that how difficult foever it may be to explain the mechanical or phyfical con- dition ofthe brain in fuch cafes, the faas are fufficient to fhow that there is fuch an inequality as mi.y difturb our intelleaual operations. 1551.] I have thus endeavoured to explain the general OF PHYSIC. 19 i caiife of Delirium; which is of two kinds, according as it is with, or without, pyrexia. Of the firft I take no fur- ther notice here, having explained it as well as I could above in (45.) I proceed now to confider that delirium which properly belongs to the clafs of Vefanise, and which I fhall treat of under the general title of Insanity. i552-] In entering upon this fubjea, it immediately occurs, that in many inftances of infanity, we find, upon diffeaion after death, that peculiar circumftances had tak- en place in the general condition of the brain. In many cafes, it has been found of a drier, harder, and firmer con- fiftence, than what it is ufually of in perfons who had not been affeaed with that difeafe. In other cafes, it has been found in a more humid, foft, and flaccid ftate ; and in the obfervations of the late Mr. Meckel,* it has been found confiderably changed in its denfity or fpecific gravity. Whe- ther thefe different ftates have been obferved to be uniform- ly the fame over the whole of the brain, I cannot certainly learn; and I fufpea the difleaors have not always accu- rately inquired into this circumftance: But in feveral inftan- ces, it appears that thefe ftates had been different in differ- ent parts of the brain; and inftances of this inequality will afford a confirmation of our general doarine. The accurate Morgagni has obferved, that in maniacal perfons the medullary portion ofthe brain is ufually dry, hard, and firm.: And this he had io frequently obferved, that he was difpofed to confider it as generally the cafe. But in moft of the particular inftances which he has given, it appears, that, for the moft part, while the cerebrum was of an unufually hard and firm con fiftence, the cerebellum was of its ufual foftnefs,.and in many ofthe cafes it was unufual- ly foft and flaccid. In fome other cafes, Morgagni obferves, that while a part of the cerebrum was harder and firmer than ordinary, other parts of it were preternaturally foft. 1553.] Thefe obfervations tend to confirm our general doarine: And there are others which I think will apply to the fame purpofe. Upon the diffeaion of the bodies of perfons who had la- bored under infanity, various organic affeaions have been # Memoir, de Berlin pour l'annee 1764. It appeared in many Inftances of infane perfons, that •he medullary fubftance of the cerebrum was drier, and of a left fpecific gravity, than in perfons who >-a ' been always of a found judgment. Author. 192 PRACTICE difcovered in particular parts ofthe brain; and it is fuffi- ciently probably, that fuch organic affeaions might have produced a different degree of excitement in the free and affeaed parts, and muft have interrupted in fome meafure the free communication between the feveral parts of the brain, and in either way have occafioned infanity. There have occurred fo many inftances of this kind, that I believe phyficians are generally difpofed to fufpe£t or- ganic lefions ofthe brain to ex ift in almoft every cafe of infanitv. 1554.J This, however, is probably a miftake: For we know that there have been many inftances of infanity, from which the perfons have entirely recovered ; and it is difficult to fuppofe that any organic leiions of the brain had in fuch cafe taken place. Such tranfitory cafes, indeed, render it probable, that a ftate of excitement, changeable by various caufes, had been the caufe of fuch inftances of infanity. 1555.] It is indeed further atferted, that in many inftan- ces of infane perfons, their brain had been examined after death, without fhowing that any organic lefions had before fubfifted in the brain, or finding that any morbid ftate of the brain then appeared. This, no doubt, may ferve to Ihow, that organic lefions had not been the caufe of the dif- eafe; but it does notaffure us that no morbid change had taken place in the brain: For it is probable, that the diffec- tors were not always aware of its being the general condi- tion of hardnefs and denfity, as different in different parts ofthe brain, that was to be attended to, in order to difcover the caufe of the preceding difeafe; and therefore many of them had not with this view examined the ftate of the brain, as Morgagni feems carefully to have done. 1556. J Having thus endeavored to inveftigate the caufe of infanity in general, it were to be wifhed that I could ap- ply the doarine to the diftinguifhing the feveral fpecies of it, according as they depend upon the different ftate and circumftances ofthe brain, and thereby to the eftablifhing of a fcientific and accurately adapted method of cure. Thefe purpofes, however, appear to me to be extremely difficult to be attained; and I cannot hope to execute them here. All I can do is to make fome attempts, and offer fome reft aaions, which further obfervation, and greater fa- gacity, may hereafter render more ufeful. OFPHYSIC. 193 - 1557-] The ingeniousTDr. Arnold has been commend- ably employed in diftinguifhing the different fpecies of in- fanity as they appear with refpea to the mind: and his la- bors may hereafter prove ufeful, when we fliall come to know fomething more ofthe different ftates of the brain correfpondmg to thefe different ftates of the mind; but at prefent I can make little application of his numerous dif- tinaions. It appears to me that he has chiefly pointed out and enumerated diftinaions, that are merely varieties, which can lead to little or no variety of praaice: And I am ef- pecially led to form the latter conclufion, becaufe thefe va- rieties appear to me to be often combined together, and to be often changed into one another, in the fame perfon; in whom we muft therefore fuppofe a general caufe of the dif- eafe, which, fo far as it can be known, muft eftablifh the pa- thology, and efpecially direa the praaice. 1558.] In my limited views of the different ftates of in- fanity, I muft go on to confider them under the two heads OT Mania and Melancholia: And though I am fenfible that thefe two genera do not comprehend the whole of the fpe- cies of infanity, I am not clear in affigning the other fpecies . which may not be comprehended under thofe titles. 1 fliall, however, endeavor, on proper occafions as I go along, to point them out as well as I can. CHAP. II. SDf s@ania, or e@atme0tf. 1559.] X HE circumftances which I have mentioned above in (1536.) as conftituting delirium in general, do more efpecially belong to that kind of it which I fhall treat of here under the title of Mania. There is fometimes a falfe perception or imagination of things prefent that are not; but this-is not a conftant, nor even a frequent, attendant o'f the difeafe. The falfe judg- ment, is of relations long before laid up in the memory. It very often turns upon one fingle fubjea; but more commonly the mind rambles from one fubjea to another with an equally falfe judgment concerning the moft part of them ; and as at the fame time there is commonly a falfe affociation, this, increafes the confufion of ideas, and 194 PRACTICE therefore the falfe judgments. What for the moft part more efpecially diftinguifhcs the difeafe is a hurry of mind, in purfuing any thing like a train of thought, and in run- ning from one train of thought to another. Maniacal per- fons are in general very irafcible; but what more particu- larly produces their angry emotions is, that their falle judgments lead to fome action which is always pufhed with impetuofity and violence; when this is interrupted or ref- irained, they break out into violent anger and furious vio- lence againft every perfon near them, and upon every thing that ftands in the way of their impetuous will. The falfe judgment often turns upon a.miftaken opinion of fome injury fuppofed to have been formerly received, or now fuppofed to be intended: and it is remarkable, that fuch an opinion is often with refpea to their former deareft friends and relations; and therefore their refentment and anger are particularly directed towards thefe. And al- though this fhould not be the cafe, they commonly foon Jofe that refpea and regard which they formerly had for their friends and relations. With all thefe circumftances, it will be readily perceived, that the difeafe muft be attend- ed very conftantly with that incoherent and abfurd fpeech we call raving. Further, with the circumftances menti- oned, there is commonly joined an unufual force in all the voluntary motions; and an infenfibility or refiftance of the force of all impreffions, and particularly a refiftance of the powers of fleep, of cold, and even of hunger; though indeed in many inftances a voracious appetite takes place. 1560.] It appears to me that the whole of thefe cir- cumftances and fymptoms point out a confiderable and unufual excefs in the excitement of the brain, efpecially with refpea to the animal funaions; and it appears at the fame time to be manifeftly in fome meafure unequal, as it very often takes place with refpecf to thefe funaions alone, while at the fame time the vital and natural are commonly very little changed from their ordinary healthy ftate. 1561. J How this excefs of excitement is produced, it may be difficult to explain. In the various inftances of what Sauvages has named the Mania Metastatica, and in all the inftances I have mentioned in my Nofology under the title of the Mania Corporea, it may be fuppofed that a morbid organic affeaion is produced in fome part of the OF pHtsrc. i95- brain; and how that may produce an increafed of unequal' excitement in certain parts of it, I have endeavoured to' explain above in (1553.) But I muft at the fame time acknowledge, that fuch remote caufes of mania have very rarely occurred; and that therefore fome other caufes of the difeafe muft. be fought for. The effeas of violent emotions or paffions of the mind have more frequently occured as the remote caufes of ma- nia; and it is fufficiently probable, that fuch violent emo- tions, as they do often immediately produce a temporary increafe of excitement, fo-they may, upon fome occafions of their permanent inherence or frequent repetition, pro- duce a more confiderable and more permanent excitement,- t that is, a mania. With refpea to thofe caufes of mania which arife in con- fequence of a melancholia which had previoufly long fub- fifted; whether we confider that melancholia as a partial infanity, or as a long perfifting attachment to one train-o? thinking, it will be readily perceived, that in either cafe fuch an increafe of excitement may take place in fo confi- derable a degree, and in fo large a portion of the brain, a? may give occafion to a complete mania. 1562.] Thefe confiderations with regard to the remote caufes appear (to me to confirm fufficiently our general doarine of increafed and unequal excitement in the mania which I have defcribed above; but 1 muft own that I have not exhaufted the fubjea, and that there arc cafes of ma- nia of which I cannot affign the remote caufes; but al- though I cannot in all cafes explain in what manner the mania is produced, I prefume, from the explanation given, and efpecially from the iymptoms enumerated above, to conclude, that the difeafe defcribed above depends upon an increafed excitement of the brain; an opinion in which I am the more confirmed, as I think it will point out the proper method of cure. At leaft I think it will moft clear- ly explain the operation of thofe remedies, which, fo far as I can learn from mv own experience and that of others, have proved the molt fuccefsful in this difeafe; and, to illultrate this, I now enter upon the confideration of thefe remedies, and to make fome remarks upon the proper manner of employing them. 1-563.3 Reftraining the anger and violence of madmen 196 T R A C T I C E is always neceffary for preventing their hurting thcmfclves or others: But this reftraint is alfo to be confidered as a re- medy. Angry paffions are always rendered more violent by the indulgence of the impetuous motions they produce; and even in madmen the feeling of reftraint will fometimes prevent the efforts which their paffion would otherwife oc- cafion. Reftraint, therefore, is ufeful, and ought to be complete; but it fhould be executed in the eafielt manner poffibly for the patient, and the {trait waiftcoat anfwers eve- ry purpofe better than any other that has yet been thought of. The reftraining madmen by the force of other men, as occafioning a conftant ftruggle and violent agitation, is often hurtful. Although, on many occafion>, it m*y not be fafe to allow maniacs tov be'upon their legs or to walk about, it is never defirable to confine them to a horizontal fituation; and whenever it can be admitted, they fhould be more or lefs in an erect pofture. Although there may be no fymptoms of any preternatural fulnefs or increafed impetus of blood in the veffels of the brain, a horizontal pofture always increafes the fulnefs and tenfion of thefe veffels, and may thereby increafe the excitement of the brain. 1564.] The reftraint mentioned requires confinement within doors, and it fliould be in a place which prefents as few objeas of fight and hearing as poffible; and particu- larly, it fhould be removed from the objeas that the pa- tient was formerly acquainted with, as thefe would more readily call up ideas and their various affociations. It is for this reafon that the confinement of madmen fliould hard- ly ever be in their ufual habitation; or if they are, that their apartment fhould be ftrippedof all its former furniture. It is alfo for the molt part proper, that maniacs fhould be without the company of any of their former acquaintance; the appearance of whom commonly excites emotions that increafe the difeafe. Strangers mav at firft be offenfive; but in a little time they come to be objeas either of indif- ference or of fear, and they fliould not be frequently changed. 1565.] Fear being a paffion ihat diminifhes excitement, may therefore be oppofed to theexcefs of it; and particu- larly to the angry and irafcible excitement of maniacs. Thefe being more fufceptible'of fear than might be expea- ed, it appears to me to have been commonly ufeful. In moft cales if ha* appeared to be neceffary to employ a ve- Oi physic. isr ry conftant impveffion of fear; and therefore to infpire them with the awe and dread of fome particular per- fons, efpecially of thofe who are to be conftantly near them. This awe and dread is therefore, by one means or other, to be acquired; in the firft place, by their being the authors of all the reftraints that may be occafionally proper; but fometimes it may be neceffary to acquire it even by ftripes and blows. The former, although having the appearance of more feverity, are much fafer than ftrokes or blows about the head. Neither of them, how- ever, fhould be employed further than feems very necef- fary, and fhould be trufted only to thofe whofe difcretion can be depended upon. There is one cafe in which they are fupcrfluous; that is, when the maniacal rage is either not fufceptible of fear, or incapable of remembering the objeas of it; for in fuch inftances, ftripes and blows would be wanton, barbarity. In many cafes of a moderate dif- eafe, it is of advantage that the perfons who are the authors of reftraint and punifhment fhould be upon other occafions the beltowers of every indulgence and gratification that isad- miffible; never, however, negleaing to employ their awe when their indulgence fhall have led to any abufe. 1566. J Although in mania, no particular irritation nor fulnefs of the fyftem feem to be prefent, it is plain, that the avoiding all irritation and means of fulnefs is proper; and therefore, that a diet neither ftimulating nor nourish- ing is commonly to be employed. As it may even be ufeful to diminifli the fulnefs of the fyftem, fo both a low and a fpare diet is likely in moft cafes to be of fervice. 1567.J Upon the fame principle, although no unufual fulnefs of the body be prefent, it may be of advantage to diminifli even its ordinary fulnefs by different evacuations. Blood-letting, in particular, might be fuppofed ufeful; and in all recent cafes of mania it has been commonly prac- tifed, and I think with advantage; but when the difeafe has fubfifted for fome time, I have feldom found bloodleuing of fervice. In thofe inftances in which there is any frequency or fulnefs of pulfe, or any marks of an increafed impetus of the blood in the veffels of the head, blood-letting is a proper and •vena neceffary remedy. Some praaitioners, in fuch cafes, have preferred to a particular manner of blood-letting, re- Vol. II. B B I9rJ PRACTICE commending arteriotomy, fcarifying the hind-head, cr opening the j ugular vein; and where any fulnefs or inflam- matory difpofition in the veffels of the brain is to be fuf- peaed, the opening the veffds neareft to them is likely to be of the greateft fervice. The opening, however, of ei- ther the temporal artery or the jugular vein in maniacal perfons is very often inconvenient; and it may generally be fufficient to open a vein in the arm, while the body is kept in fomewhat of an erea pofture, and fuch a quantity of blood drawn as nearly brings on a deliquiuni animi, which is always a pretty certain mark of fome diminution ofthe fulnefs and tenfion of the veffels of the brain. 1568.] For the fame purpofe of taking off the fulnefs and tenfion of thefe veffels of the brain, purging may be employed; and I can in no other view underftand the ce- lebrated uie of hellebore among the ancients. 1 cannot, however, fuppofe anv fpecific power in hellebore; and can by no means find that, at leaft the black hellebore, is fo efficacious with us as it is faid to have been at Anticyra. As coftivenefs, however, is commonly a very conftant and hurtful attendant of mania, purgatives come to be fometimes very neceffary; and I have known fome bene- fit obtained from the frequent ufe of pretty draftiG purga- tives. In this, however, I have been frequently difap- pointed; and I have found more advantage from the fre- quent ufe of cooling purgatives, particularly foluble tar- tar, than from more draftic medicines. 1569.} Vomiting has alfo been frequently employed in mania; and by determining powerfully to the furface of the body, it may poffibly diminifh the fulnefs and tenfion ofthe veffels, and thereby the excitement of the brain; but I have never carried the ufe of this remedy fo far as might enable me to judge properly of its effects. Whether it may do harm by impelling the blood too forcibly into the veffels of the brain, or whether by its general agitation of the whole fyftem it may remove that inequality of excite- ment which prevails in mania, I have not had experience enough to determine. 1570.] Frequent fhaving of the head has been found of fervice in mania, and by promoting perfpiration it probably takes off from the excitement of the internal parts. This, however, it is likely, may be more effeaually done by OF PHYSIC 119 bliftering, which more certainly takes off the excitement of fubjacent parts. In recent cafes it has been found ufe- ful by inducing fleep; and when it has that effea, the re- petition of it may be proper: but in manical cafes that have lafted for fome time, bliftering has not appeared to me to be of any fervice; and in fuch cafes alfo I have not found perpetual blifters, or any other form of iffue, prove ufeful. 1571. J As heat is-the principal means of firft exciting the nervous fyftem, and eftablifliing the nervous power and vital principle in animals: fo, in cafe of preternatural 1 excitement, the application of cold might be fuppofed a proper remedy: but there are many inftances of maniacs who have been expofed for a great length of time to a con- fiderable degree of cold without having their fymptoms anywife relieved. This may render in general the applica- tion of cold a doubtful remedy; but it is at the fame time certain, that maniacs have often been relieved, and fome- times entirely cured, by the ufe of cold bathing, efpecially when adminiftered in a certain manner. This feems to confift, in throwing the madman in the cold water by fur- prife; by detaining him in it for fome length of time; and pouring water frequently upon the head, while the whole ofthe body except the head is immerfed in the water; and thus managing the whole procefs, fo as that, with the aflift- ance of fome fear, a refrigerant effea may be produced. This, I can affirm, has been oPten ufeful; and that the external application of cold may be of fervice, w7e know further from the benefit which has been received in fome ma- niacal cafes from the application of ice and fhow to the naked head, and from the application of the noted Clay Clap. Warm bathing alfo has been recommended by fome praaical writers; and in fome rigid melancholic habits k may poffibly be ufeful, or asemploycd in the manner pre- fcribed by fome, of immerfing the lower parts of the body in warm water, while cold water is poured upon the head and upper parts. jjOf this praaice, however, I have had no experience, and in the common manner of employing warm bathing I have found it rather hurtful to maniacs. 1572.] According to my fuppofition that the difeafe de- pends upon an increafed excitement of the brain, efpecially with refpea to the. animal funaions, opium, fo commonly 2*0 PRACTICE powerful in inducing fleep, or a confiderable collapfe as to thefe functions, fhould be a powerful remedy of mania. That it has truly proved fuch, I believe from ibe teftimony of Bernard Iluet, whofe praClice is narrated at the end of Wepferi Hiftoria Apopleaicorum. I leave to my readers to ftudy this in the work I have referred to, where every part of the praaice is fully, and it appears ir> me, very ju- dicioufly delivered. I have never indeed carried the trial fo far as feems to be requifite to an entire cure : but I have frequently employed in fome maniacal cafes large dofes of opium; and when they had the effect of inducing fleep, it was manifeftly with advantage. At the fame time, in fome cafes, from doubts, whether the difeafe might not depend upon fome organic lefions of the brain, when the opium would be fuperfluous; and in other cafes, from doubts, whether there might not be fome inflammatory affeaion joined with the mania, when the opium would be hurtful, I have never pufhed this remedy to the extent that might be neceffary to make an entire cure. 1573.} Camphire has been recommended as a remedy ©f mania, and there are inftances alledged of its having per- formed an entire cure. As it appears from the experiments of Beccaria that this fubftance is poffeffed of a fedative and narcotic virtue, thefe cures are not altogether improbable: but in feveral trials, and even in large dofes, I have found no benefit from it; and excepting thofe in the Philosophi- cal Tranfactions, No. 400. I have hardly met with any other teftimonies in its favour. 1574.J I have been informed that fome maniacs have been cured by being compelled to conftant? and even hard labour; and as a forced attention to the-condua of any bodily exercife is a very certain means of diverting the mind from purfuing any train of thought, it is highly pro- bable that fuch exercife may be ufeful in many cafes of mania. I muft conclude this fubjea with observing, that even in feveral cafes of complete mania I Have known a cure take place in the courfe of a journey carried on for fome length of time. 1575.] Thefe are the remedies which have been chieflv employed in the mania that has been above defcribed, and I believe they have been employed promifcuoufly without OF P H Y S I C. 201 fuppofing that the mania was to be diftinguifhed into differ- ent fpecies. Indeed I am not ready to fay how far it is to be fo diftinguifhed, but I fliall offer one obfervation which may poffibly merit attention. it appears to me that there are two different cafes of ma- nia that are efpecially different according to the original temperament of the perfons whom the difeafe affeas. It perhaps occurs moft frequently in perfons of a melancho- lic or atrabilarian temperament; but it certainly does alfo often occur in perfons of that very oppofite temperament which phyficians have named the Sanguine. According as the difeafe happens to occur in perfons of the one or other of thefe temperaments I apprehend it may be confidered as of a different nature; and I believe, that accurate ob- fervation, employed upon a fufficient number of cafes, would difcern fome pretty conftant difference, either of the fymptoms, or at leaft of the ftate of fymptoms, in the two cafes. I imagine that falfe imaginations, particular averfions and refentments, are more fixed and fteady in the melancholic than in the fanguine; and that fomewhat inflam- matory is more commonly joined with mania in the fanguine than in the melancholic. If fuch difference, however, does truly take place, it will be obvious, that it may be proper to make fome difference alfo in the praaice. I am of opin- ion, that in the mania of fanguine perfons, bloodletting and other antiphlogiftic meafures are more proper, and have been more ufeful, than in the melancholic. I likewife appre- hend that cold bathing is more ufeful in the fanguine than in the melancholic : But I have not had experience enough to afcertain thefe points with fufficient confidence. I have only to add to this other obfervation, that maniacs of the fanguine temperament recover more frequently and more entirely than thofe of the melancholic. CHAP. III. £Df apelanc&oip ami otfrer jFormg of 3|n0anitp,. 1576.] JVLeLANCHOLY has been commonly confi- dered as partial infanity; and as fuch it is defined in my Nofology: but I now entertain doubts if this be altogether proper. By a partial infanity, I underftand a falfe and mif- 202 PRACTICE taken judgment upon one particular fubjea, and what re- lates to it; whilft, on every other fubjea, the perfon af- feaed judges as the genefality of other men do. Such cafes have certainly occurred; but, I believe, few in which the partial infanity is ftriaiy limited. In many cafes of general infanity, there is one fubjea of anger or fear, upon which the falfe judgment more particularly turns, or which is at leaft more frequently than any other the prevailing ob- ject of delirium: and though, from the inconfiftency which this principal objea of delirium muft produce, there is there- fore alfo a great deal of infanity with regard to moft other objeas; yet this laft is in very different degrees, both in different perfons, and in the fame perfon at different times. Thus perfons confidered as generally infane, will, however, at times, and in fome cafes, pretty conftantly judge proper- ly enough of prefent circumftances and incidental occur- rences; though, when thefe objeas engaging attention are not prefented, the operations of imagination may readily bring back a general confufion, or recal the particular ob- jea of the delirium. From thefe confiderations, I am in- clined to conclude, that the limits between general and par- tial infanity cannot always be fo exaaiy afligned, as to de- termine when the partial affeaion is to be confidered as giving a peculiar fpecies of difeafe, different from a more general infanity. 1577-3 When infanity, neither ftriaiy partial, nor en- tirely nor conftantly general, occurs in perfons of a fanguine temperament, and is attended with agreeable, rather than with angry or gloomy emotions, I think fuch a difeafe muft be confidered as different from the Mania defcribed above; and alfo, though partial, muft be held as different from the prpper Melancholia to be mentioned hereafter. 1578.] Such a difeafe, as different from thofe defcribed (1555.) requires, in my opinion, a different adminiftration of remedies; and it will be proper for me to take particu- lar notice of this here. Although it may be neceffary to reftrain fuch infane per- fons as we have mentioned (1577.) fr°m purfuing the ob- jeas of their falfe imagination or judgment, it will hardly be requifite to employ the fame force of reftraint that is ne- ceffary in the impetuous and angry mania. It will be ge- nerally fufficient to acquire fome awe over them, that may O F P H Y S I C. 303 be employed, and fometimes even be neceffary, to check the rambling of their imagination, and incoherency of judgment. 1579-j The reftraint juft now mentioned as neceffary will generally require the patient's being confined to one place, for the fake of excluding the objects, and more par- ticularly the perfons, that might excite ideas conneaed with the chief objeas of their delirium. At the fame time, however, if it can be perceived there are objeas or perfons that can call off their attention from the purfuit of their own difordered imagination, and fix it a little upon fome others, thefe laft may be frequently prefented to them: and for this reafon, a journey, both by its having the effea of inter- rupting all train of thought, and by prefenting objeas en- gaging attention, may often be ufeful. In fuch cafes alfo, when the infanity, though more efpecially fixed upon one miftaken fubjefct, is not confined to this alone, but is fur- ther apt to ramble over other fubjeas, with incoherent ideas, I apprehend the confining or forcing fuch perfons to-* fome conftant uniform labor, may prove an ufeful remedy. 1580. J When fuch cafes as in (1577.) occur in fanguine temperaments, and may therefore approach more nearly to Phrenitic Delirium; fo, in proportion as the fymptoms of this tendency are more evident and confiderable, blood- letting and purging will be the more proper and neceffary. 1581.] To this fpecies of infanity, when occurring in fanguine temperaments, whether it be more or lefs partial, I apprehend that cold bathing is particularly adapted; while, in the partial infanity of melancholic perfons, as I fhall fhow hereafter, it is hardly admiffible. 1582.] Having thus treated of a fpecies of infanity, dif- ferent, in my apprehenfion, from both the Mania and Me- lancholia, I proceed to confider what feems more properly, to belong to this laft. 1583.] The difeafe which I name Melancholia is very often a partial infanity only. But as in many inftances, though the falfe imagination of judgment feems to be with refpea to one fubjea only; yet it feldom happens that this does not produce much inconfiftency in the other intellec- tual operations: And as, between a very general and a very partial infanity, there are all the poffible intermediate de- grees; fo it will be often difficult, or perhaps improper, to diftinguifh melancholia by the charaaer of Partial Infanity 204 PRACTICE alone. If I miftake not, it muft be chiefly diftinguifhed by its occurring in perfons of a melancholic temperament, and by its being always attended with fome feemingly groundlefs, but very anxious fear. 1584.] To explain the caufe of this, I muft obferve, that perfons of a melancholic temperament are for the molt part of a ferious thoughtful difpofition, and difpofed to fear and caution, rather than to hope and temerity. Perfons of this caft are lefs moveable than others by any impref- fions; and are therefore capable of a clofer or more contin- ued attention to one particular objea, or train of thinking. They are even ready to be engaged 111 a conftant applica- tion to one fubjea; and are remarkably tenacious of what- ever emotions they happen to be affeaed with. 1585.] Thefe circumftances ofthe melancholic charac- ter, feem clearly to fhew, that perfons ftrongly affeaed with it may be readily feized with an anxious fear; and that this, when much indulged, as is natural to fuch perfons, may eafily grow into a partial infanity. 1586. J Fear and dejection of mind, or a timid and def- ponding difpofition, may arife in certain ftates, or upon certain occafions of mere debility: and it is upon this foot- ing, that I fuppofe it fometimes to attend dyfpepfia. But in thefe cafes, I believe the defpondent difpofition hardly ever arifes to a confiderable degree, or proves fo obftinate- ly fixed as when it occurs in perfons of a melancholic tem- perament. In thefe laft, although the fear proceeds from the fame dyfpeptic feelings as in the other cafe, yet it will be obvious, that the emotion may arife toa more confiderable degree; that it may be more anxious, more fixed, and more attentive; and therefore may exhibit all the various cir- cumftances which I have mentioned in (1222.) to take place in the'difeafe named Hypochondriasis. 15^7-J 1° confidering this fubjea formerly in diftin- guifhing Dyfpepfia from Hypychondriafis, although the fymptoms affecting the body be very much the fame in both, and even thofe affeaing the mind be fomewhat fimi- lar, I found no difficulty in diftinguifhing the latter difeafe, merely from its occurring in perfons of a melancholic tem- perament. But I muft now acknowledge, that I am at a lofs to determine how in all cafes hypochondriafis and me- OF PHYSIC. 20J lancholia may be diftinguifhed from one another, whilft the fame temperament is common to both. 1588.] I apprehend, however, that the diftinaion may be generally afcertained in the following manner. The hypochondriafis I would confider as being always attended with dyfpeptic fymptoms: And though there may be, at the fame time, an anxious melancholic fear arifing from the feeling of thefe fymptoms; yet while this fear is only a miftaken judgment with refpe6t to the ftate of the perfon's own health, and to the danger to be from thence apprehended, I would ftill confider the difeafe as a hypo- chondriafis, and as diftina from the proper melancholia. But when an anxious fear and defpondency arifes from a miftaken judgment with refpea to other circumftances than thofe of health, and more efpecially when the perfon is at the fame time without any dyfpeptic fymptoms, every one will readily allow this to be a difeafe widely different from both dyfpepfia and hypochondriafis; and it is, what I would ftriaiy name Melancholia. 1589.J In this there feems little difficulty; but as an ex- quifitely melancholic temperament may induce a torpor and ffownefs in the aaion of the ftomach, fo it generally produces fome dyfpeptic fymptoms; and from thence there may be fome difficulty in diftinguifhing fuch a cafe from hy- pochondriafis. But I would maintain, however, that when the charaaers ofthe temperament are ftrongly mark^k and more particularly when the falfe imagination turnsllpon other fubjeas than that of health, or when, though relative to the perfon's own body, it is of a groundlefs and abfurd kind; then, notwithftanding the appearance of fome dyfpep- tic fymptoms, the cafe is ftill to be confidered as that of a melancholia, rather than a hypochondriafis. 1590.] The difeafe of melancholia, therefore manifeftly depends upon the general temperament of the body: and although, in many perfons, this temperament is not attend- ed with any morbid affeaion either of mind or body; yet when it becomes exquifitely formed, and is in a high degree, it may become a difeafe affeaing both, and particularly the mind. It will therefore be proper to confider in what this melancholic temperament efpecially confifts; and to this purpofe, it may be obferved, that in it there is a degree of Vol. II. C c 20fJ PRACTICE torpor in the motion of the nervous power, both with rcf- pecf to fenfation and volition; that there is a general rigid- ity of the fimple folids; and that the balance of the fan- guiferous fyftem, is upon the fide of the veins. But aH thefe circumftances are the direaiy oppofite of thofe ofthe fanguine temperament; and muft therefore alfo produce an oppofite ftate of mind. 1591.J It is this ftate ofthe mind, and the ftate ofthe brain correfponding to it, that is the chief objea of our pre- fent confideration. But what that ftate of the brain is, will be fuppofed to be difficult to explain; and it may perhaps feem rafh in me to attempt it. I will, however, venture to fay, that it is probable the melancholic temperament of mind depends upon, a drier and firmer texture in the medullary fubftance ofthe brain; and that this perhaps proceeds from a certain want of fluid in that fubftance, which appears from its being of a leffer fpe- cific gravity than ufual. That this ftate of the brain in melancholia does aaually exift, I conclude, first, from the general rigidity of the whole habit; and, secondly, from dif- feaions, fhowing fuch a ftate of the brain to have taken place in mania, which is often no other than a higher degree of melancholia. It does not appear to me any wife difficult to fuppofe, that the fame ftate of the brain may in a mo- derate degree give melancholia; and in a higher, that mania which melancholia fo often paffes into; efpecially if I fhall be allowed further to fuppofe, that either a greater degree of firmnefs in the fubftance of the brain may render it fuf- ceptible of a higher degree of excitement, or that one por- tion of the brain may be liable to acquire a greater firmnefs than others, and confequently give occafion to that inequal- ity of excitement upon which mania fo much depends. J592'] I hive thus endeavored to deliver what appears to me moft probable with refpea to the proximate caufe of melancholia; and although the matter fliould in fome refpeas remain doubtful, I am well perfuaded that thefe ob- fervations may often be employed to direa our praaice in this difeafe, as I fhall now endeavor to fhow. 1 S93J In moft ofthe inftances of melancholia, the mind is to be managed very much in the fame manner as I have advifed above with regard to hypochondriafis; but as in the cafe of proper melancholia, there is commonly afalfeima- OF PHYSIC. 307 ^nation or judgment appearing as a partial infanity, it may be further neceffary in fuch cafes to employ fome artifices for corre£ting fuch imagination or judgment. 1594* J Tfie various remedies for relieving the dyfpeptic fymptoms which always attend hypochondriafis, will feldom be eiuier requifite or proper in melancholia. There is only one of the dyfpeptic fymptoms, which, though there fhould be no other, is very conftantly prefent in melancholia, and that is coftivenefs. This it is always proper and even neceffary to remove; and I believe it is upon this account that the ufe of purgatives has been found fb often ufeful in melancholia. Whether there be any pur- gatives peculiarly proper in this cafe, I dare not pofitively determine; but with refpea to the choice of purgatives in, melancholia, I am of the fame opinion that I delivered above on this fame fubjec^ with refpe6t to mania. 1595.] With refpea to other remedies, I judge that blood-letting will more feldom be proper in melancholia than in mania; but how far it may be in any cafe proper, muft be determined by the fame confideration as in the cafe of mania. 1596.J The cold bathing that I judged to be fo very ufeful in feveral cafes of infanity, is, I believe, in melan- cholia, hardly ever fit to be admitted; at leaft while this is purely a partial affeaion, and without any marks of violent excitement. On the contrary, upon account ofthe gener- al rigidity prevailing in melancholia, it is probable that warm bathing may be often ufeful.. 1597.J With refpea to opiates which I have fuppofed might often be ufeful in cafes of mania, I believe they can feldom be properly employed in the partial infanities of the melancholic, except in certain inftances of violent ex- citement, when the melancholia approaches nearly to the ftate of mania. 1598.J In fuch cafes of melancholia approaching to a ftate of mania, a low diet may fometimes be neceffary; but as the employing a low diet almoft unavoidably leads to the ufe of vegetable food, and as this in every torpid ftate of the ftomach is ready to produce fome dyfpeptic fymp- toms, fuch vegetable food ought, in moderate cafes of me- lancholia, to be ufed with fome caution. Though exercife, as a tonic power, is not proper either 205 PRACTICE in hypochondriafis or melancholia; yet, with refpea to its effects upon the mind, it may be extremely ufeful in both, and in melancholia is to be employed in the fame manner that I have advifed above in the cafe of hypochondriafis. J599.] Having now delivered my doctrine with refpea to the forms of infanity, I fliould in the next place proceed < to confider the other genera of Amentia and Oneirodynia, J which in the Nofology I have arranged under the order of I Vefaniae; but as I cannot pretend to throw much light up- on thefe fubjeas, and as they are feldom the objeas of praaice, I think it allowable for me to pafs them over at prefent; and the particular circumftances of this work in fome meafure require that I fliould do fo. ii ' ■ — PART III. Of CACHEXIES. 1600.] U NDER this title I propofe toeftablifh a clafs of difeafes, which confift in a depraved ftate of the whole, or of a confiderable part, of the habit of the body, without any primary pyrexia or neurofis combined with that ftate. 1601. J The term Cachexy has been employed by Lin- naeus and Vogel, as it had been formerly by other authors, for the name of a particular difeafe; but the difeafe to which thefe authors have affixed it, comes more properly under another appellation; and the term of Cachexy is more pro- perly employed by Sauvages and Sagar for the name of a clafs. In this I have followed the laft-mentioned nofolo- gifts, though I find it difficult to give fuch a charaaer of the clafs as will clearly apply to all the fpecies I have compre- hended under it. This difficulty would be ftill greater, if, in the clafs I have eftablifhed under the title of Cachexies, I were to comprehend all the difeafes that thofe other no- fologifts have done; but I am willing to be thought defi- cient rather than very incorrea. Thofe difficulties, how- ever, which ftill remain in methodical nofology, muft not affea us much in a treatife of praaice. If I can here pro- perly diftinguifh and defcribe the feveral fpecies that truly and moft commonly exift, I fhall be the lefs concerned about the accuracy of my general claflification ; though at OFPHYSIC '2€r9 the fame time this, I think, is always to be attempted; and I fhall purfue it as well as I can. , ______ .... _____•_ BOOK I. Of E M 4 cTa T I 0 N S. 1602.] HjMACIATION, or a confiderable diminution of the bulk or plumpnefs of the whole body, is for the moft part only a fymptom of difeafe, and very feldom to be con- fidered as a primary and idiopathic affeaion. Upon this account, according to my general plan, fuch a fymptom might perhaps have been omitted in the Methodical Nofo- logy : but both the uncertainty of concluding it to be al- ways fymptomatic, and the confiftency of fyftem, made me introduce into the Nofology, as others had done, an order under the title of Marcores; and this renders it requifite now to take fome notice of fuch difeafes. 1603.] Upon this occafion, therefore, I hope it may be ufeful to inveftigate the feveral caufes of emaciation in all the different cafes of difeafe in which it appears. And this I attempt, as the fureft means of determining how far it is a primary, or a fymptomatic affeaion only; and even in the latter view, the inveftigation may be attended with fome advantage. 1604. J The caufes of emaciation may, I apprehend, be referred to two general heads; that is, either to a general deficiency of fluid in the veffels of the body, or to the par- ticular deficiency of the oil in the cellular texture of it.* Thefe caufes are frequently combined together; but it will be proper, in the firft place, to confider them feparately. 1605.] As a great part of the body of animals is made up of veffels filled with fluids, the bulk of the whole muft depend very much on the fize of thefe veffels, and the quan- tity of fluids prefent in them : and it will therefore be fuffi- ciently obvious, that a deficiency of the fluids in thefe vef- fels muft, according to its degree, occafion a proportionate diminution of the bulk of the whole body. This, how- ever, will appear ftill more clearly, from confidering that in the living and found body the veffels every where feem * Might not a third caufe be added, viz. a deficiency of the folid parts 1 21ft PRACTICE to be preternaturally diftended by the quantity of fluids prefent in them; but being at the fame time elaftic, and conftantly endeavouring to cohtraa themfelves, they muft on the withdrawing of the diftending force, or, in other words, upon a diminution of the quantity of fluids, be in proportion contraaed and diminifhed in their fize. And it may be further obferved, that as each part of the vafcular fyftem communicates with every other part of it; fo every degree of diminution of the quantity of fluid, in any one part, muft in proportion diminifh the bulk of the vafcular fyftem, and confequently of the whole body.* 1606. J The diminution and deficiency of the fluids may be occafioned by different caufes: fuch as, firft, by a due quantity of aliments not being taken in; or by the aliment taken in not being of a fufficiently nutritious quality. Of the want of a due quantity of aliment not being taken into the body, there is an inftance in the atrophia lactantium Sauvagelii, fpecies 3. and many other examples have oc- curred of emaciation from want of food, occafioned by po- verty, and other accidental caufes. With refpea to the quality of food, I apprehend it arifes from the want of nutritious matter in the food em- ployed, that perfons living entirely on vegetables are fel- dom of a plump and fucculent habit.t -1607.] A fecond caufe of the deficiency of fluids may be, the aliments taken in not being conveyed to the blood- veffels. This may occur from a perfon's being affeaed with a frequent vomiting; which, rejeaing the food foon after it had been taken in, muft prevent the neceffary fup- ply of fluids to the blood-veffeb.J Another caufe, fre- quently interrupting the conveyance of the alimentary matter into the blood-veffels, is an obftruaion of the con- globate lymphatic glands of the mefentery, through which the chyle muft neceffarily pafs to the thoracic duct. Many inftances of emaciation, feemingly depending upon this * There may, however, be a partial without a jeneral emaciation, as is the cafe in a palfied limb • but this partial diminution of bulk In the difeafed limb is not owing to a leflened quantity of the ge- neral mafs of the circulating fluids, but to the languid circulation in that part, the arteries not pro- pelling the blood through it with fufficient vigor. " v t As the author fays at the conclusion of thischapter, " After having confidered the various caufe* of emaciations, I fliould perhaps treat of their cure: but it will readifv appear, that the greater pare of the cafes above mentioned are purely fymptomatic, and confequently that the cure ofthem mult be that of the primary difeafes upon which they depend. Of thofe cafes that can any wife be con- fidered as idiopathic, it will appear that they are to be cured entirely by removing the remote caufes •'* it may not be improper to treat of the cure as we proceed. This fpecies of emaciation may be obvioufly cured by a rich and nutritious diet. t This fpecies may be cured bypreventing the vomiting by antifpafmodics, efpecially opium, and by the ufe of gentle laxatives occafioually.

It has alfo been remarked, that fuch cafes have moft frequently occurred in ferophu- lous perfons, in whom the mefenteric glands are common- ly affeaed with tumour or obftruaion, and in whom, ge- nerally at the fame time,- fcrophula appears externally. Hence the Tabes scrophulosa Synop. Nosolog. vol. ii. p. 266. And under thefe I have put as fynonimes Tabes glandularis, fp. 10. Tabes mescnterica, fp. 9. Scrophula mesenterica, fp. 4. Atrophia infantilis, fp. 13. Atrophia rachitica, fp. 8. Tabes rachialgica, fp. 16. At the fame time, I have frequently found the cafe occurring in per- fons who did not fhow any external appearance of fcro- phula, but in whom the mefenteric obftruaion was after- wards difcovered by diffeaion. Such alfo I fuppofe to have been the cafe in the difeafe frequently mentioned by authors under the title of the Atrophia infantum. This has received its name from the time of life at which it ge- nerally appears; but I have met with inftances of itatfour- teen years of age afcertained by diffeaion. In feveral fuch cafes which I have feen, the patients were without anv fero- phulous appearances at the time, or at any period of their lives before.* In the cafe of phthifical perfons, I fliall hereafter men- tion another caufe of their emaciation; but it is probable that an obftruaion of the mefenteric glands, which fo fre- quently happens in fuch perfons, concurs very powerfully in producing the emaciation that takes place. Although a ferophulous taint may be the moft frequent caufe of mefenteric obftruaions, it is fufficiently probable that other kinds of acrimony may produce the fame, and the emaciation that follows. It may perhaps be fuppofed, that the interruption of the chyle's palling into the blood-veffels may be fometimes ow- ing to a fault of the abforbents on the internal furface of the inteftines. This, however, cannot be readily afcer- tained: but the interruption of the chyle's palling into the blood-veffels may certainly be owing to a rupture of the thoracic dua; which, when it does not prove foon fatal, * Thefe cafes are generally incurable; if, however, there be no fufpicion of fcrophula, we may at- tempt a cure by endeavoring to removethe ooftrudtion either by invigorating the habit, or by active aperients.

It is not, however, eafy to afcertain the cafes of emaciation which are to be attributed to this caufe; but I apprehend that the emaciation which attends long fubfifting cafes of dyfpepfia, or of hypochon- driafis, is to be explained chiefly in this way. It is this which I have placed in the Nofology under the title of the Atrophia deb}lium; and of which the Atrophia Nervosa, Sauv. fp. 1. is a proper inftance, and therefore put there as a fynonime. But the other titles of Atrophia Lateralis, Sauv. fp. 15. and Atrophia senilis, Sauv. fp. 11. are not fo properly put there, as the y muft be explained in a different manner.t 1609.] A fourth caufe of a deficiency ofthe fluids in the body, may be exceffive evacuations made from it by differ- ent outlets; and Sauvages has properly enumerated the following fpecies, which we have put as fynonimes under the title of Atrophia inanitorum,; as, Tabes nutricum, fp. 4; Atrophia nutricum, fp. 5; Atrophia a leucorrhcea, fp. 4; Atrophia ab alvi filuxu, fp. 6; Atrophia d ptyalismo, fp. 7; and laftly, the Tabes d sanguifluxu; which, it is to be obferved, may arife not only from fpontaneous hemor- rhagies or accidental wounds, but alfo from blood-letting in too large a quantity, and too frequent repeated. Upon this fubjea it feems proper to obferve, that a mea- gre habit of body frequently depends upon a full perfpira- tion being conftantly kept up, though at the fame time a large quantity of nutritious aliment is regularly taken in.J 1610. J Befides this deficiency of fluids from evacuations by which they are carried entirely out ofthe body, there may be a deficiency of fluid and emaciation in a confider- able part of the body, by the fluids being drawn into one part, or colleaed into one cavity; and of this we have an inftance in the Tabes a hydrope, Sauv. fp. ij..|| * This is an abfolute incurable difeafe. + This fpecies of emaciation may be fuecelsfully cured by the means of thofe remedies mentioned in the Notes on Articles 1104. 1206. mo. 1212. 1213. inc. 1216. 1221. X In thefe cafes aftringents are the principal remedies on which we muft, depend'; and thofe aftrin* pt nts muft be chofen which arc adapted to fupprefs the peculiar evacuation that occafions the difeafe. ■i The emaciation from this caufe is merely fymptomatic, and can only be cured oy curing the jitn-.-y dileale. '- O F P H Y S I C. 211 1611.] In the Methodical Nofology, among the other, fynonimes of the Atrophia inanitorum I have fet down the Tabes dorsalis; but whether properly or not, I at prefent verv much doubt. In the evacuation confidered as the caufe of this tabes, as the quantity evacuated is never i'o great as to account for a general deficiency of fluids in the body, we muft feek for another explanation of it. And whether the effeas ofthe evacuation may be accounted for, either from the quality ofthe fluid evacuated, or from the fingularly enervating pleafure attending the evacuation, or from the evacuation's taking off the tenfion of parts, the tenfion of which has a finguiar power in fupporting the ten- fion and vigour of the whole body, I cannot pofitively de- termine; but I apprehend that upon one or other of thefe fuppolitions the emaciation attending the tabes dorsalis muft be accounted for; and therefore, that it is to be confidered as an inftance ofthe Atrophia debilium, rather than of the Atrophia inanitorum* 1612. J A fifth caufe of a deficiency of fluids and of emaciations in the whole or in a particular part of the body, may be the concretion of the fmall veffels, either not ad- mitting of fluids, or of the fame proportion as before; and this feems to me to be the cafe in the Atrophia senilis, Sauv. fp. 2. Or it may be a palfy of the larger trunks ofthe arte- ries rendering them unfit to propel the blood into the fmaller veffels; as is frequently the cafe of paralytic limbs, in which the arteries are affeaed as well as the mufcles. The Atro- phia lateralis, Sauv. fp. 15, feems to be of this nature.t 1613. J A fecond general head ofthe caufes of emacia- tion I have mentioned in (1603.) to be a deficiency of oil. The extent and quantity of the cellular texture in every part of the body, and tlierefore how confiderable a part it makes in the bulk of the whole is now well known. But this fubftance, in different circumftances, is more or lefs filled with an oily matter; and therefore the bulk of it, and in a great meafure that of the whole body, muft be greater or lefs according as this fubftance is more or lefs filled in that manner. The deficiency of fluids, for a reafon to be im- mediately'explained, is generally accompanied with a de ficiency of oil: But phyficians have commonly attended * If a particular abominable praaice be the caufe, it muft be abandoned before a cure can be ""t&s is one ofthe Incurable fpecies of emaciation, and it can only be relieved by a very nutrit \vv and invigorating djet. VOL. Ii. £> B *14 PRACTICE more to the latter caufe of emaciation than to the oi/.er, that being ufually the moft evident; and I fhall now endea- vour to affign the feveral caufes of the deficiency of oil as it occurs upon different occafions. 1614.] The bufinefs of lecretion in the human body is in general little underftood, and in no inftance lefs fo thai. in that of the fecretion of oil from blood which does not appear previoufly to have contained i;. It is poffible, therefore, that our theory of the deficiency of oil may be in feveral refpeas imperfea; but there are certain facts that may in the mean time apply to the prefent purpofe. 1615.] Firft, it is probable, that a deficiency of oil may be owing to a ftate of the blood in animal bodies lefs fitted to afford a fecretion of oil, and confequently to fup- ply the watte of it that is conftantly made. This ftate of the blo.cl muft efpecially depend upon the ftate of the ali- ments taken in, as containing lefs of oil or oily matter. From many obfervations made^ both with refpea to the human body and to that of Other animals, it appears pretty clearly, that the aliments taker) in by men and domeftic animals, according as they contain more of oil, are in ge- neial more nutritious, and in particular are better fitted to fill the cellular texture of their bodies with oil. I might illuftrate this, by a minute and particular confideration of the difference of alimentary matters employed; but it will be enough to give twTo inftances. The one is, that the herbaceous part of vegetables does not fatten animals, fo- much as the feeds of vegetables, which manifeftly contain in any given weight a greater proportion of oil ; and a fecond inftance is, that in general vegetable aliments do not fatten men fo much as animal food, which generally contains a larger proportion of oil. It will be obvious, that upon the fame principles a want of food, or a lefs nutritious food, may not only occafion a general deficiency of fluids (1605.) DUt mual ai^° afford lefs oil, to be poured into the cellular texture. In fuch cafes, therefore, the emaciation produced, is to be attri- buted to both thefe general caufes.* 1616. j A fecond cafe of the deficiency of oil may be explained in this manner. It is pretty manifeft, that the j oil of the blood is fecreted and depofited in the cellular * The ewe of tbfrljpecitt of emaciation wiEbeoeft effettedbyarich i'.t'-.c! animal food. OF PHYSIC. 215 texture in greater or leffer quantity, according as the cir- culation of the blood is fafter or flower ; and therefore that exercife, which haftens the circulation ofthe blood, is a frequent caufe of emaciation. Exercife produces this ef- fea in two ways, ift, By increafing the perfpiration, and thereby carrying off a greater quantity of the nutritious matter, it leaves lefs of it to be depofited in the cellular texture; thereby not only preventing an accumulation of fluids, but, as I have faid above, caufing a general defi- ciency of thefe, which muft alfo caufe a deficiency of oil in the cellular texture, sdly, It is well known, that the oil depofited in the cellular texture is upon many occafi- ons, and for various purpofes of the economy, again ab- forbed, and mixed or diffufed in the mafs of blood, to be irom thence perhaps carried entirely out of the bodv by the feveral excretions. Now, among other purpofes of the accumulation and reabfoption of oil, this feems to be one, that the oil is requifite to the proper aaion of the moving fibres in every part of the body; and therefore that nature has provided for an abforption of oil to be made according as the aaion of the moving fibres may demand it. It will thus be obvious, that the exercife of the mufcu- lar and moving fibres every where, muft occafion an ab- forption of oil; and confequently that fuch exercife not only prevents the fecretion of oil, as has been already faid, but may alio caufe a deficiency of it, by occafioning an abforption of what had been depofited; and in this way perhaps efpecially, does it produce emaciation.* 1617.] A third cafe ofthe deficiency of oil may occur from the following caufe. It-is probable, that one pur- pofe of the accumulation of oil in the cellular texture of animals is, that it may, upon occafion, be again abforbed from thence, and carried into the mafs of blood, for the purpofe. of enveloping and correaing any unufual acrimo- ny arifing and exifting in the ftate ofthe fluids. Thus, in moft inftances in which we can difcern an acrid ftate of the fluids, as in fcurvy, cancer, fyphilis, poifons, and feve- ral other difeafes, we find at the fame time a deficiency of oil and an emaciation take place; which, in my apprehenfion, muft be attributed to the abforption of oil, which the pre- fence of acrimony in the body excites. * Abftinence from too fevere exercife is the only cure for th:.; fpecies of the difeafe. 2 IS PRACTICE It is not unlikely- that certain poifons introduced into the body, may fubfift there; and, giving occafion to an ab- forption of oil, may lay a foundation for the Tabes a ve- neno, Sauv. fp. 17.* 1618.J A fourth cafe of emaciation, and which I would attribute toafuddenand conhderablcabforption of oil from the cellular texture, is that of fever, which fo generally pro- duces emaciation. This may perhaps be in part attributed to the increafed perfpiration, and therefore to ihe general deficiency of fluids that may be fuppofed to take place : but whatever fhare that may have in producing the effea, we can, from the evident flirinking and diminution of the cellular fubftance, wherever it fall's under our obfervation, certainly conclude, that there has been a very confidetable abforption of the oil which had been before depofited in that Jubilance. This explanation is rendered the more probable from this, that I fuppofe the abforption mention- ed is neceffarily made for the purpofe of enveloping or cor- reaing an acrimony, which manifeftly does in many, and and may be fufpeaed to arife in all, cafes of lever. The moft remarkable inftance of emaciation occurring in fevers, is that which appears in the cafe of heaic fevers. Here the emaciation may be attributed to the profufe fweatings that commonly attend the difeafe; But there is much reafon to believe, that an acrimony alfo is prefent in the blood; which, even in the beginning of the difeafe, prevents the fecretion and accumulation of oil; and in the more ad- vanced ftates of it, muft occafion a more confiderable ab-. forption of it; which, from the fhrinking of the cellular fubftance, feems to go farther than in almoft any other in- ftance.t Upon the fubjea of emaciations from a deficiency of fluids, it may be obferved, that every increafed evacuati- on excites an abforption from other parts, and particularly from the cellular texture; and it is therefore probable, that a deficiency of fluids, from increafed evacuations, produces an emaciation, not only by the watte of the fluids # As this kind of emaciation proceeds from various caufes, the practitioner muft, after having af- certained the true caufe, endeavor to remove it: and this mult be left entirely to his own fagacity. It may however be proper to obferve, that feveral of thefe emaciations proceed from incurable difea- fes _; as from Cancer, Scrophula, &c. and confequently admit of no cure : And thofe emaciations which proceed from fcurvy, fyphilis, or thofe difeafes which we can cure, are only to be cured by curing the primary difeafe. + This emaciation is purely fymptomatic, and consequently cannot be cured hut by removing the primary difeafe, and a fubfequent very nutritious aiet, ccnuiu.-.^ chiefly cf ,-jima: fool. OF PHYSIC. 2 IT in the vafcular fyftem, but alfo by occafioning a confider- able abforption from the cellular texture. 1619.] I have thus endeavoured to explain the feveral cafes and caufes of emaciation; but I could not profecute the confideration of thefe here in the order they are fet down in the Methodical Nofology. In that work I was engaged chiefly in arranging the Species of Sauvages; but it is my opinion now, that the arrangement there given is erroneous in both combining and feparating fpecies im- properly : And it feems to me more proper here to take notice of difeafes, and put them together, according to the affinity of their nature, rather than by that of their ex- ternal appearances. I doubt, if even the diftinaion ofthe Tabes and Atrophia, attempted in the Nofology, will pro- perly apply; as I think there are certain difeafes of the lame nature, which fometimes appear with, and fometimes without, fever. 162.0.J After having confidered the various cafes of emaciations, I fhould perhaps treat of their cure: But it will readily appear, that the greater part of the cafes above mentioned are purely fymptomatic, and confequently that the cure of them muft be that of the primary difeafes upon which they depend. Of thofe cafes that can anywife be confidered as idiopathic, it will appear that they are to be cuied entirely by removing the remote caufes; the means of accomplifhmg which muft be fufficiently obvious.

I. 1622.] J_ HE only difeafe to be mentioned in this chap- ter, I have, with other Nofologifts, named Polysarcia; and in Englifli it may be named Corpulency, or, more itriaiy, Obefity; as it is placed here upon the common fuppofition of its depending chiefly upon the increafe of oil in the cellular texture of the body. This corpulency, or obefity, is in very different degrees in different perfons, ani is often confiderable without being confidered as a dif- eafe. There is, however, a certain degree of it, which will be generally allowed to be a difeafe; as, for example, when it renders perfons, from a difficult refpiration, uneafy in themfelves, and, from the inability of exercife, unfit for difcharging the duties of life to others: And for that reafon I have given fuch a difeafe a place here. Many phyficians have confidered it as an "objed of praaice, and as giving,' even in a very high degree, a difpofition to ma- ny difeafes; J am of opinion that it fhould be an objea of . praaice more frequently than it has been, and therefore that it merits our confideration here. 1623.] It may perhaps be alledged, that I have not been fufficiently correa, inputting the difeafe of corpulency as an intumefcentia pinguedinofa, and therefore implying its being an increafe of the bulk of the body from an accumu- lation of oil in the cellular texture only. I am aware of' this objeaion: and as I have already laid, that emaciation {1604.) depends either upon a general deficiency of fluids in the vafcular fyftem, or upon a deficiency of oil in the cellular texture; fo I fhould perhaps have obferved farther, that the corpulency, or general fulnefs of the body, may depend upon the fulnefs of the vafcular fyftem as well as upon, that of the cellular texture. This is true; and for the fame reafons I ought, perhaps, after Linnaeus and Sa- gar, to have fet down plethora as a particular difeafe, and as an inftance of morbid intumefcence. I have, however, avoided this, as Sauvages and Vogel have done; becaufe I O F P H y SIC. 2i9 apprehend that plethora is to be confidered as a ftate of temperament only, which may indeed difpofe to difeaf-; but not as a difeafe in itfelf, unlefs, in tire language of the Stahlians, it be a plethora commota, when it produces a dif- eafe accompanied with particular fymptoms, which give oc- cafion to its being diftinguifhed by a differcm appellation. Further, it appears to me, that the fymptoms which Lin- naeus, and more particularly thofe which Sagar employs in the character of plethora, never do occur but when the m- tumefeentia pinguedinofa has a great fhare in producing them. It is, however, very neceffary to obferve here, that plethora and obefity are generally combined together; and that in fome cafes of corpulency it may be difficult to deter- mine which ofthe caufes has the greateft fhare in producing it. It is indeed very poffible that a plethora may occur without great obefity; but I apprehend that obefity never happens to a confiderable degree without producing a ple- thora ad spatium in a great part of the fyftem of the aorta, and therefore a plethora ad molem in the lungs, and in the veffels of the brain. 1624.] In attempting the aire of polyiarcia, I «-.m of opinion that the conjunaion of plethora and obefity, m the manner juft now mentioned, fhould be conftantly attended to; and when the morbid effeas of the plethoric habit art" threatened, either in the head or lungs, that blood-letting is to be praaifed: but at the fame time it is to be obferved, that perfons of much obefity do not bear blood-letting well;. and when the circumftances I have mentioned do not im- mediately require it, the praaice upon account of obefity alone, is hardly ever to be employed. The fame remark is to be made with refpea to any other evacuations that may be propofed for the cure of corpulency: for without the other means I am to mention, they can give but a very im- perfea relief; and, in fo far as they can either empty 01 weaken the fyftem, they may favor the return of plethora, and the increafe of obefity. 1625.] Polyfarcia, or corpulency, whether it depend upon plethora or obefity, whenever it either can be confi- dered as a difeafe, or threatens to induce one, is to be cur- ed, or the effeas of it are to be obviated, by diet and exer- cife. The diet muft be fparing; or rather, what is more admiffiblej it mufl be fuch as affords little nutritious mat* £20 P R A C T I C E' ter. It fnuft therefore be chieflv, or almoft only, of vegeta- ble matter, and at the very utmoft of milk. Such a diet fhould be employed, and generally ought to precede cxer- cife: for obefity does not eafily admit of bodily cxercife j which is, however, the onlv mode tffat can be very effedua!. Such, indeed, in many cafes, may feem difficult to be ad- mitted; but I am of opinion, that even the moft corpulent may be brought to bear it, by at firlt attempting it very moderately, and increafing it by degrees very (lowly, but at the fame time perfilting in fuch attempts with great con- ftancy.* 1626.] As thefe. though the only effeaual meafures, are often difficult to be admitted or carried into execution, fome other means have been thought of and employed for reducing corpulency. Thefe, if I miftake not, have all been certain methods of inducing a faline ftate in the mafs of blood; for fuch I fuppofe tobe the clfc-as of vinegar and of foap, which have been propofed. I'he latter, I believe, hardly paffes into the blood-vcffels, without being refolved and formed into a neutral fait, with the acid which it meets with in the ftomach. How well acrid and faline fubftances are fitted to diminifh obefity, may appear from what has been faid above in (1616.) What effeas vine- gar, foap, or other fubftances employed, have had in re- * dueins; corpulency, there have not proper opportunities of ■obferving occurred to me: But I am well perfuaded, that the inducing a faline and acrid ftate of the blood, may have worfe confequences than the corpulency it was in- tended to correct; and that no perfon fliould hazard thefe, while he may have recourfe to the more fafe and certain means of abftinence and exercife. CHAP. II. £)f JFiatulent ^toeliingai. 1627.] X HE cellular texture of the human body very readily admits of air, and allows the fame to pafs from any one to every other part of it. Hence Emphyfemata have often appeared from air colleaed in the cellular texture under the fkin, and in feveral other parts ofthe body. The * Befides the mear.s mentioned by the author, evacuatic-.-i if different kinds ought to be occaflon- alry made, efpecially by purging and fweating. OF PHYSIC, 221 flatulent fwellings under the fkin, have indeed moft com- monly appeared in confequence of air immediately intro- duced from without: But in fome inftances of flatulent fwellings, efpecially thofe of the internal parte not com- municating with the alimentary canal, fuch an introduaion cannot be perceived or fuppofed; and therefore, in thefe cafes, fome other caufe of the produaion and colfeaion of air muft be looked for, though it is often not to be clearly afcertained. In every folid as well as every fluid fubftance which makes a part of the human body, there is a confiderable quantity of air in a fixed ftate, which may be again reftored to its elaftic ftate, and feparated from thofe fubftances, by the power of heat, putrefacfion, and perhaps other caufes: But which of thefe may have produced the feveral inftan- ces of pneumatofis and flatulent fwellings that have been recorded by authors, I cannot pretend to afcertain. In- deed upon account of thefe difficulties, I cannot proceed with any clearnefs on the general fubjecf of pneumatofis; and therefore, with regard to flatulent fwellings, I find it neceffary to confine my felf to the confideration of thofe of the abdominal region alone; which I fhall now treat of un- der the general name of Tympanites. 1628.J The tympanites is a fwelling of the abdomen; in which the teguments appear to be much ftretched by fome diftending power within, and equally ftretched in every pofture of the body. The fwelling does not readily yield to any preffure; and in fo far as it does, very quick- ly recovers its former ftate upon the preffure being removed. Being ftruck, it gives a found like a drum, or other ftretch- ed animal membranes. No fluctuation within is to be per- ceived; and the whole feels lefs weighty than might be ex- peaed from its bulk. The uneafinefs of the diftention is commonly relieved by the difcharge of air from the ali- mentary canal, either upwards or downwards. 1629.] Thefe are the chafers by which the tympanites may be diftinguifhed from the afcites or phyfeonia; and many experiments fhow, that the tympanites always de- pends upon a preternatural colfeaion of air, fomewhere within the teguments of the abdomen: But the feat of the air is in different cafes fomewhat different; and this pro- duces the different fpecies of the difeafe. Vol. II. E E 222 PRACTICE One fpecies is, when the air colleaed is entirely confin- ed within the cavity of the alimentary canal, and chiefly in that of the inteftines. This fpecies, therefore, ?s named the Tympanites intestinalis, Sauv. fp. 1. It is, of all others, the moft common; and to it efpecially belong the charac- ters given above. A fecond fpecies is, when the air colleaed is not en- tirely confined to the cavity of the inteftines, but is alfo prefent between their coats; and fuch is that which is nam- ed by Sauvages Tympanites enterophysodes, Sauv. fp. 3. This has certainly been a rare occurrence; and has proba- bly occurred only in confequence of the tympanites intes* tinalis, by the air efcaping from the cavity of the inteftines into the interftices of the coats. It is, however, poffible that an erofion of the internal coat of the inteftines may give occafion to the air, fo conftantly prefent in their ca- vity, to efcape into the interftices of their coats, though in the whole of their cavity there has been no previous accu- mulation. A third fpecies is, when the' air is colleaed in the fac of the peritonaeum, or what is commonly called the cavity of the abdomen, that is, the fpace between the peritonaeum and vifcera; and then the difeafe is named Tympanites ab- dominalis, Sauv. fp. 2. The exiftence of fuch a tympan- ites, without any tympanites intestinalis^ has been difputed; and it certainly has been a rare occurrence: But from fe- veral diffeaions, it is unqueftionable that fuch a difeafe has fometimes truly occurred. A fourth fpecies of tympanites is, when the tympanites intestinalis and abdominalis are joined together, or take place at the fame time. With refpea to this, it is probable that the tympanites intestinalis is the primary difeafe ; and the other, only a confequence of the air efcaping, by an e- rofion or rupture of the coats of the inteftines, from the ca- vity of thefe into that of the abdomen. It is indeed poffible that in confequence of erofion or rupture, the air which is fo conftantly prefent in the inteftinal canal, may efcape from thence in fuch quantity into the cavity of the abdomen, as to give a tympanites abdominalis, whilft there was no pre- vious confiderable accumulation of air in the inteftinal ca- vity itfelf; but I have not faas to afceruin this matter properly. ( OF PHYSIC. 223 A fifth fpecies has alfo been enumerated. It is when a tympanites abdominalis happens to be joined with the hy- drops ascites; and fuch a difeafe therefore is named by Sau- vages Tympanites asciticus, Sauv.fp. 4. In moft cafes of tympanites, indeed, fome quantity of ferum has, upon dif- feaion, been found in the fac of the peritonaeum ; but that is not enough to conftitute the fpecies now mentioned; and when the colfeaion of ferum is more confiderable, it is com- monly where, both from the caufes which have preceded, and likewife from the fymptoms which attend, the afcites may be confidered as the primary difeafe; and therefore that this combination does not exhibit a proper fpecies of the tympanites. 1630.] As this laft is not a proper fpecies, and as fome of the others are not only extremely rare, but even, when occurring, are neither primary, nor to be eafily diftinguifh- ed, nor, as confidered in themfelves, admitting of any cure, I fhall here take no further notice of them ; confining my- felf, in what follows, to the confideration of the moft fre- quent cafe, and almoft the only objea of praaice* the tym- panites intestinalis* 1.6-3,1.] With refpea to this, I cannot perceive that it a- rifes in any peculiar temperament, or depends upon any predifpofition, which can be difcerned. It occurs in ei- ther fex, at every age, and frequently in young perfons. 1632.} Various remote caufes of it have been affigned : But many of thefe have not commonly the effect of produ- cing this difeafe; and although fome of them have been truly antecedents of it, I can in few inftances difcover the man- ner in> which they produce the difeafe, and therefore cannot certainly afcertain them to have been caufes of iu 1633.] The phenomena of this difeafe in its feveraf fta- ges are the following. The tumour of the belly fometimes grows very quickly to a confiderable degree, and feldom in the flow manner the afcites commonly comes on. In fome cafes, howTever, the tympanites comes on gradually, and is introduced by an unufual flatulency of the ftomach and inteftines, with frequent borborygmy, and an uncommonly frequent ex- pulfion of air upwards and downwards. This ftate is alfo frequently attended with colic pains, efpecially felt about the navel, and upon the fides towards die back ^ but gep.e- 224 PRACTICE rally as the difeafe advances, thefe pains become lefs con- fiderable. As the difeafe advances, there is a pretty con- ftant defire to difcharge air, but it is accomplifhed with difficulty; and when obtained, although it give fome relief from the fenfe of diftention, this relief is commonly tran- fient and of fhort duration. While the difeafe is coming on, fome inequality of tumour and tenfion may be perceiv- ed in different parts of the belly; but the diftention foon becomes equal over the whole, and exhibits the phenome- na mentioned in the charaaer. Upon the firft coming on of the difeafe, as well as during its progrefs, the belly is bound, and the faeces difcharged are commonly hard and dry. The urine, at the beginning, is ufually very little changedin quantity or quality from its natural ftate: But as the difeafe continues, it is commonly changed in both refpeas; and at length fometimes a ftranguary, and even an ifchuria, comes on. The difeafe has feldom advanced far, before the appetite is much impaired, and digeftion ill performed; and the whole body, except the belly, becomes confiderably emaciated. Together with thefe fymptoms, a thirft and uneafy fenfe of heat at length come on, and a confiderable frequency of pulfe occurs, which continues throughout the courfe of the difeafe. When the tumour of the belly arifes to a confiderable bulk, the breathing be- comes very difficult, with a frequent dry cough. With all thefe fymptoms the ftrength of the patient declines; and the febrile fymptoms daily increafing, death at length enfues, fometimes probably in confequence of a gangrene coming upon the inteftines. 1634. J The tympanites is commonly of fome duration, and to be reckoned a chronic difeafe. It is very feldom quickly fatal, except where fuch an affeaion fuddenly arifes in fevers. To this Sauvages has properly given a deferent appellation, that of Meteorismus; and I judge it may always be confidered as a fymptomatic affection, en- tirely diftina from the tympanites we are now confidering. 1635.] The tympanites is generally a fatal difeafe, fel- dom admitting of cure; but what may be attempted in this way, I fhall try to point out, after I fhall have endeavour- ed to explain the proximate caufe, which alone can lay the foundation of what may be rationally attempted towards its cure, OF PHYSIC! 525 1636.] To afcertain the proximate caufe of tympanites, is fomewhat difficult. It has been fuppofed in many cafes, to be merely an uncommon quantity of air prefent in the alimentary canal, owing to the extrication and detachment of a greater quantity of air than ufual from the alimentary matters taken in. Our vegetable aliments, I believe, al- ways undergo fome degree of fermentation ; and in confe- quence, a quantity of air is extricated and detached from them in the ftomach and inteftines: But it appears, that the mixture of the animal fluids which our aliments meet with in the alimentary canal, prevents the fame quantity of air from being detached from them that would have been in their fermentation without fuch mixture; and it is pro- bable that the fame mixture contributes alfo to the reab- forption of the air that had been before in fome meafure detached. The extrication, therefore, of an unufual quantity of air from the aliments, may, in certain circum- ftances, be fuch, perhaps as to produce a tympanites; fo that this difeafe may depend upon a fault of the digeftive fluids, whereby they are unfit to prevent the too copious extrication of air, and unfit alfo to occafion that reabforp- tion of air which in found perfons commonly happens. An unufual quantity of air in the alimentary canal, whether owing to the nature of the aliments taken in, or to the fault of the digeftive fluid, does certainly fometimes take place; and may poffibly have, and in fome meafure certainly has, a fhare in producing certain flatulent diforders of the ali- mentary canal; but cannot be fuppofed to produce the tympanites, which often occurs when no previous diforder had appeared in the fyftem. Even in thofe cafes of tym- panites which are attended at their beginning with flatulent diforders in the whole of the alimentary canal, as we know that a firm tone of the inteftines both moderates the extri- cation of air and contributes to its reabforption or ready expulfion, fo the flatulent fymptoms which happen to ap- pear at the coming on of a tympanites, are, in my opinion, to be referred to a lofs of tone in the mufcular fibres of the inteftines, rather than to any fault in the digeftive fluids. 1637.] Thefe, and other confiderations, lead me to con- clude, that the chief part of the proximate caufe of tympa- nites, is a lofs of tone in the mufcular fibres of the inteftines. But further, as air of any kind accumulated in the cavity of <.2S PRACTICE the inteftines fhould, even by its own clafticity, find its way either upwards or downwards, and fhould alfo, by the at- fiftance of infpiration, be entirely thrown out of the body; fo, when neither the reabfoption nor the expulfion takes place, and the air is accumulated fo as to produce tympa- nites, it is probable that the paffage of the air along the courfe ofthe inteftines is in fome places of thefe interrupt- ed. This interruption, however, can hardly be fuppofed to proceed from any other caufe than fpafmodic conftric- tions in certain parts ofthe canal; and I conclude, there- fore, that fuch conftriaions concur as part in the proximate caufe of tympanites.—Whether thefe fpafmodic conttric- tions are to be atributed to the remote caufe of the difeafe, or may be confidered as the confequence of fome degree of atony firft arifing, I cannot with certainty, and do not find it neceffary to determine. 1638. J Having thus endeavoured to afcertain the proxi- mate caufe of tympanites, I proceed to treat of its cure; which indeed has feldom fucceeded, and almoft never but in a recent difeafe. I muft, however, endeavour to fay what may be reafonably attempted; what has commonly been attempted; and what attempts have fometimes fuc- ceeded in the cure of this difeafe. 1639.J It muft be a firft indication to evacuate this air accumulated in the inteftines: and for this purpofe it is ne- celiary that thofe conftriaions, which had efpecially occa- fioned its accumulation, and continue to interrupt its paf- fage along the courfe of the inteftines fhould be removed. As diefe, however, can hardly be removed but by exciting the periftaltic motion in the adjoining portions of the intef- tines, purgatives have been commonly employed; but it is at the fame time agreed, that the more gentle laxatives on- ly ought to be employed, as the more draftic, in the over- fhetched and tenfe ftate of the inteftines, are in danger of bringing on inflammation. It is for this reafon, alfo, that glyfters have been frequent- ly employed; and they are the more neceffary, as the faeces collected are generally found to be in a hard and dry ftate. Not only upon account of this ftate of the fasces, but, far- ther, when glyfters produce a confiderable evacuation of air, and thus fhow that they have fome effea in relaxing the fpafms of the inteftines, they ought to be repeated very frequently. OF PHYSIC. 227 1640.] In order to take off the conftriaions of the in- teftines, and with fome view alfo to the carminative effeas of the medicines, various antifpafmodics have been propof- ed, and commonly employed; but their effeas are feldom confiderable, and it is alledged that their heating and inflam- matory powers have fometimes been hurtful. It is, how- ever, always proper to join fome ofthe milder kinds with both the purgatives and glyfters that are employed;* and it has been very properly advifed to give always the chief of antifpafmodics, that is, an opiate, after the operation of purgatives is finiflied. 1641. J In confideration of the overftretched tenfe, and dry ftate of the inteftines, and efpecially of the fpafmodic conftriaions that prevail, fomentations and warm bathing have been propofed as a remedy; and are faid to have been employed with advantage: but it has been remarked, that very warm baths have not been found fo ufeful as tepid baths long continued. 1642.] Upon the fuppofition that this difeafe depends efpecially upon an atony of the alimentary canal, tonic re- medies feem to be properly indicated. Accordingly cha- lybeates, and various bitters, have been employed; and, if any tonic, the Peruvian bark might probably be ufeful. 1643.] But as no tonic remedy is more powerful than cold applied to the furface of the body, and cold drink thrown into the ftomach; fo fuch a remedy has been thought of in this difeafe. Cold drink has been conftantly prefcribed, and cold bathing has been employed with advantage; and there have been feveral inftances of the difeafe being fud- denly and entirely cured by the repeated application of fnow to the lower belly. 1644.] It is hardly neceffary to remark, that, in the diet of tympanitic perfons, all forts of food ready to become flatulent in the ftomach are to be avoided; and it is proba- ble, that the foffil acids and neutral falts, as antizymics, may be ufeful.t 16*45.] In °bftinate and defperate cafes of tympanites, * The antifpafmodics that are to be joined with purgatives ought to be effential olU, efpecially the effential oils of umbelliferous plants, as oil of annffccd, oil of carui, &c. and their dofe ought to be moderate. In manv cafes they may be ufed in repeated fmall dofes by themfelves oa a piece of fu- ear. 'Hie dofe of the ol. anifi ought not to exceed ten or twelve drops, nor of the: ol. carui hvc 5rops; larcer dofes arc too heating. It may be proper aho to obferve, that the effential oils of the verticellated plants, as mint, marjoram, thyme, &c. are much too heating, and much more fo thofe of tlie aromatics, as cloves, cinnamon, &c. . . . . + The foffil acids arc undoubtedly very powerful in refitting fermentation; and It tW air in tH« iatcftincii is produced by ienucnuuon, they art confequently nlgbly ufeful. 22S PRACTICE the operation of the paracentefis has been propofed: but it is a very doubtful remedy, and there is hardly any tefti- mony of its having been praaifed with fuccefs. It muft be obvious, that this operation is a remedy fuited efpecial- ly, and almoft only, to the tympanites abdominalis; the exiftence of which, feparately from the intestinalis, is very doubtful, at leaft not eafily afcertained. Even if its exift- ence could be afcertained, yet it is not very likely to be cured by this remedy; and how far the operation might be fafe in the tympanites intestinalis, is not yet determined by any proper experience. CHAP. III. 1646.] A. PRETERNATURAL colfeaion of ferous or watery fluids, is often formed in different parts ofthe human body; and although the difeafe thence arifing be diftinguifhed according to the different parts which it oc- cupies, yet the whole of fuch colfeaions come under the general appellation of Dropfies. At the fame time, al- though the particular inftances of fuch colfeaion are to be diftinguifhed from each other according to the parts they occupy, as well as by other circumftances attending them; yet all of them feem to depend upon fome general caufes, very much in common to the whole. Before proceeding, therefore, to confider the feveral fpecies, it may be proper to endeavour to affign the general caufes of dropfy. 1647.] In perfons in health, a ferous or watery fluid feems to be conftantly poured out, or exhaled in vapour, into every cavity and interftice of the human body capable of receiving it; and the fame fluid, without remaining long or being accumulated in thefe fpaces, feems conftant- ly to be foon again abforbed from thence by veffels adapted to the purpofe. From this view of the animal economy, it will be obvious, that if the quantity poured out into any fpace, happens to be greater than the abforbents can at the fame time take up, an unulual accumulation of ferous flu- id will be made in fuch parts; or though the quantity poured o«:t bs not more than ufual, yet if the abforption OF PHYSIC. 229 be anywife interrupted or diminifhed, from this caufe alfo an unufual colfeaion of fluids may be occafioned. Thus, in general, dropfy may be imputed to an increaf- ed effufion, or to a diminiihed abforption; and I therefore proceed to inquire into the feveral caufes of thefe. 1648.3 An increafed effufion may happen, either from a preternatural increafe of the ordinary exhalation, or from the rupture of veffels carrying, or of facs containing, fe- rous or watery fluids. 1649. J The ordinary exhalation may be increafed by various caufes, and particularly by an interruption given to the free return of the venous blood from the extreme veffels of the body to the right ventricle of the heart. This interruption feems to operate by refifting the free paflageof the blood from the arteries into the veins, thereby increaf- ing the force of the arterial fluids in the exhalants, and con- fequently the quantity of fluid which they pour out. 1650. J The interruption ofthe free return ofthe venous blood from the extreme veflels, may be owing to certain circumftances affeaing the courfe of the venous blood; very frequently, to certain conditions in the right ventricle of the heart itfelf, preventing it from receiving the ufual quantity of blood from the vena cava; or to obftruaions in the veffels ofthe lungs preventing the entire evacuation of the right venticle, and thereby hindering its receiving the ufual quantity of blood from the cava. Thus, a poly- pus in the right ventricle of the heart, and the oflification of its valves, as well as all confiderable and permanent ob- ftruaions of the lungs, have been found to be caufes of dropfy. 1651.] It may ferve as an wluftration of the operation of thefe general caufes, to remark, that the return of the venous blood is in fome meafure refitted when the pofture of the body is fuch as gives occafion to the gravity of the blood to oppofe the motion of it in the veins, which takes effea when the force of the circulation is weak; and from whence it is that an upright pofture of the body produces or increafes ferous fwellings in the lower extremities. 1652.] Not only thofe caufes interrupting the motion of the venous blood more generally, but', farther, the in- terruption of it in particular veins, may likewife have the Vor.. II. F f 250 PRACTICE effea of increafing exhalation, and producing dropfy.. The moft remarkable inftance of this is, when confiderable obftrufctions of the liver prevent the blood from flowing freely into it from the vena portarum and its numerous branches; and hence thefe obftru6tions are a frequent caufe of dropfy. 1653.J Scirrhofities of the fpleen and other vifcera, as well as the feirrhofity of the liver, have been confidered as caufes of dropfy; but the manner in which they can pro- duce the difeafe, I do not perceive, except it may be where they happen to be near fome confiderable vein, by the compreffion of which they may occafion fome degree of afcites; or, by compreffing the vena cava, may pro- duce an anafarca of the lower extremities. It is indeed true, that feirrhofities of the fpleen and other vifcera, have been frequently difcovered in the bodies of hydropic per- fons: But I believe that they have been feldom found un- lefs when feirrhofities of the liver were alfo prefent; and I am inclined to think, that the former have been the effeas of the latter, rather than the caufe of the dropfy; or that, if feirrhofities ofthe other vifcera have appeared in hydro- pic bodies when that of the liver was not prefent, they muft have been the effe6ts of fome of thofe caufes of dropfy to be hereafter mentioned; and confequently to be the acci- dental attendants, rather than the caufes, of fuch dropfies. 1654.] Even in fmaller portions ofthe venous fyftem, the interruption of the motion of the blood in particular vqins has had the fame effea. Thus a polypus formed in the cavity of a vein, or tumours formed in its coats, pre- venting the free paffage ofthe blood through it, have had the effea of producing dropfy in parts towards the extremi- ty of fuch veins. 1655 J But the caufe moft frequently interrupting the motion of the blood through the veins is, the compreffion of tumours exifting near to them; fuch as aneurifms in die arteries, abfeeffes, and fcirrhous or fteatomatous tumours in the adjoining parts. To this head may be referred the compreffion of the defcending cava by the bulk of the uterus in pregnant wo- men, and the compreffion ofthe fame by the bulk of wa- ter in the afcites; both of which compreffions frequently produce ferous fwellings in the lower extremities. OF PHYSIC. 251 1656. J It may be fuppofed, that a general preternatural plethora ofthe venous fyftem may have the effea of in- creafing exhalation; and that this plethora may happen from the fuppreffion of fluxes, or evacuations of blood, which had for fome time taken place in the body, fuch as the menftrual and hemorrhoidal fluxes. A dropfy, how- ever, from fuch a caufe, has been at leaft a rare occurrence; and when it feems to have happened, I fhould fuppofe it owing to the fame caufes as the fuppreffion itfelf, rather than to the plethora produced by it. 1657.] One of the moft frequent caufes of an increafed exhalation, I apprehend to be the laxity of the exhalant veffels. That fuch a caufe may operate, appears probable from this, that paralytic limbs, in which fuch a laxity is to be fufpected, are frequently affeaed wkh ferous, or, as they are called, cedematous fwellings. But a much more remarkable and frequent example of its operation occurs in the cafe of a general debility of the fyftem, which is fo often attended with dropfy. That a general debility docs induce dropfy, appears fufficiently from its being fo commonly the confequence of powerful- ly debilitating caufes; fuch as fevers, either of the continu- ed or intermittent kind, which have lafted long; long con- tinued and fomewhat exceflive evacuations of any kinds; and in fhort, almoft all difeafes that have been of long con- tinuance, and have at the fame time induced the other fymptoms of a general debility. Among other caufes inducing a general debility ofthe fyftem, and thereby dopfy, there is one to be mentioned as frequently occurring, and that is, intemperance in the ufe of intoxicating liquors; from whence it is that drunk- ards of all kinds, and efpecially dram-drinkers, are fo af- feaed with this difeafe. 1658. ] That a general debility may produce a laxity of the exhalants, will be readily allowed: and that by this ef- pecially it occafions dropfy, I judge from thence, that while moft of the caufes already mentioned are fuited to produce dropfies of particular parts only, the ftate of general debi- lity gives rife to increafed exhalation into every cavity and and interftice of the body, and therefore brings on a gener- al difeafe. Thus, we have feen effufions of a ferous fluid . made, at the fame time, into the cavity of the cranium, in- 232 PRACTICE to that ofthe thorax and of the abdomen, and likewife in- to the cellular texture almoft over the whole of the body. In fuch cafes, the operation of a general caufe difcovered itfelf, by thefe feveral droplies increafing in one part as they diminifhed in another, and this alternately in the different parts. This combination, therefore, of the different fpe- cies of dropfy, or rather, as it may be termed, this univer- sal dropfy, muft, I think, be referred to a general caufe; and in moft inftances, hardly any other can be thought of, but a general laxity of the exhalants. It is this, therefore, that I call the hydropic diathesis; which frequently ope- rates by itfelf; and frequently, in fome meafu e, concur- ring with other caufes, is efpecially that which gives them their full effea. This ftate of the fyftem, in its firft appearance, feems to be what has been confidered as a particular difeafe under the name of Cachexy ; but in every inftance of it that has occurred to me, I have always confidered, and have always found, it to be the beginning of general dropfy. 1659.] ^he feveral caufes of dropfy already mentioned may produce"the difeafe, although there be no preternatu- ral abundance of ferous or watery fluid in the blood-vef- fels; but it is now'to be remarked, that a preternatural abundance of that kind may often give occafion to the dif- eafe, and more efpecially when fuch abundance concurs with the caufes above enumerated. One caufe of fuch preternatural abundance may be an unufual quantity of water taken into the body. Thus an unufual quantity of water taken in by drinking, has fome- times occafioned a dropfy. Large quantities of water, it is true, are upon many occafions taken in; and being as rea- dily thrown out again by ftool, urine, or perfpiration, have not produced any difeafe. But it is alfo certain, that, upon fome occafions, an unufual quantity of watery li- quors taken in has run off by the feveral internal exhalants, and produced a dropfy. This feems to have happened, either from the excretories not being fitted to throw out the fluid fo faft as it had been taken in, or from the excretories having been obftruaed by accidentally concurring caufes. Accordingly it is faid, that the fudden taking in of a large quantity of very cold water, has produced dropfy, probably from the cold producing a conftriaion of the excretories. OF PHYSIC. 233 The proportion of watery fluid in the blood may be in- creafed, not only by the taking in a large quantity of water by drinking, as now mentioned, but it is poffible that it may be increafed alfo by water taken in from the atmof- phere by the fkin in an abforbing or imbibing ftate. It is well known that the fkin may be, at leaft, occafionally in fuch a ftate; and it is probable, that in many cafes of be- ginning dropfy, when the circulation of the blood on the furface of the body is very languid, that the fkin may be changed from a perfpiring to an imbibing ftate; and thus, at leaft, the difeafe may be very much increafed. 1660.J A fecond caufe of a preternatural abundance of watery fluids in the blood-veffeLs, may be, an interruption of the ordinary watery excretions; and accordingly it is ailedged, that perfons much expofed to a cold and moift air are liable to dropfy. It is alfo faid, that an interrup- tion, or confiderable diminution, of the urinary fecretion, has produced the difeafe: and it is certain, that, in the cafe of an ischuria renalis, the ferofity retained in the blood- veffels has been poured out into fome internal cavities, and has occafioned dropfy. 1661. J A third caufe, of an over proportion of ferous fluid in the blood ready to run off by the exhalants, has been very large evacuations of blood, either fpontaneous or artificial. Thefe evacuations, by abftraaing a large proportion of red globules and gluten, which are the prin- cipal means of retaining ferum in the red veffels, allow the ferum to run off more readily by the exhalants: And hence dropfies have been frequently the confequence of fuch eva- cuations. It is poffible alfo, that large and long-continued iffues, by abftraaing a large porportion of gluten, may have the fame effea. An over-proportion ofthe ferous parts ofthe blood, may not only be owing to the spoliation juft now mentioned, but may, I apprehend, be likewife owing to a fault in the digefting and alfimilating powers in the ftomach and other organs; whereby they do not prepare and convert the ali- ments taken in, in fuch a manner as to produce from them the due proportion of red globules and gluten; but, ftill continuing to fupply the watery parts, occafion thefe to be in an over-proportion, and confequently ready to run off 134 PRACTICE in too large quantity by the exhalants. It is in this man- ner that we explain the dropfy, fo often attending chlorofis: which appears always at firft by a pale colour of the whole body, fhowing a manifeft deficiency of red blood; which in that difeafe can only be attributed to an imperfect* digef- tion and affimilation. Whether a like imperfeaion takes place in what has been called a Cachexy, I dare not determine. This difeafe in- deed has been commonly and very evidently owing to the general caufes of debility above-mentioned: and it being probable that the general debility may affea the organs of digeftion and affimilation; fo the imperfett. ftate of thefe funaions, occafioning a deficiency of red globules and glu- ten, may often concur with the laxity of the exhalants in producing dropfy. 1662.] Thefe are the feveral caufes of increafed exhala- tion, which I have mentioned as the chief caufe of the ef- fufion producing dropfy; but I have likewife obferved in (1648.) that with the fame effea, an effufion may alfo be made by the rupture of veffels carrying watery fluids. In this way, a rupture of the thoracic dua, has given oc- cafion to an effufion of chyle and lymph into the cavity of the thorax; and a rupture of the laaeals has occafioned a like effufion into the cavity ofthe abdomen; and in either cafe, a dropfy has been produced. It is fufficiently probable, that a rupture of lymphatics, in confequence of ftrains, or the violent compreffion of neighbouring mufcles, has occafioned an effufion; which, being diffufed in the cellular texture, has produced dropfy. It belongs to this head of caufes, to remark, that there are many inftances of a rupture or erofion of the kidney, ureters, and bladder of urine; whereby the urine has been poured into the cavity of the abdomen, and produced an afcites. 1663.] Upon this fubjea, of the rupture of veffels car- rying, or of veficles containing, watery fluids, I muft ob- ferve, that the diffeaion of dead bodies has often fhown veficles formed upon the furface of many of the internal parts; and it has been fuppofed, that the rupture of fuch veficles, commonly named Hydatides, together with their continuing to pour out a watery fluid, has been frequently the caufe of dropfy. I cannot deny the poffibility of fuch O F P H Y S I C. iii a caufe, but fufpea the matter muft be explained in a dif- ferent manner. There have been frequently found, in almoft every dif- ferent part of animal bodies, colfeaions of fpherical vefi- cles, containing a watery fluid; and in many cafes of fup- pofed dropfy, particularly in thofe called the preternatural encylted droplies, the fwelling has been entirely owing to a colfeaion of fuch hydatides. Many conjectures have been formed with regard to the nature and produaion of thefe veficles: but the matterat laft feems to be afcertained. It feems to be certain, that each of thefe veficles has with- in it, or annexed to it, a living animal of the worm kind; which feems to have the power of forming a veficle for the purpofe of its own economy, and of filling it with a wa- tery fluid drawn from the neighbouring parts: And this animal has therefore been properly named by late natura- lifts the Tcenia hydatigena. The origin and economy of this animal, or an account of the feveral parts of the hu- man body which it occupies, I cannot profecute further here; but it was proper for me, in delivering the caufes of dropfy, to fay thus much of hydatides: And I muft con- clude with obferving, I am well perfuaded, that moft of the inftances of preternatural encyfted droplies which have appeared in many different parts ofthe human body, have been truly colfeaions of fuch hydatides; but how the fwellings occafioned by thefe are to be diftinguifhed from other fpecies of dropfy, or how they are to be treated in praaice, I cannot at prefent determine. 1664.] After having mentioned thefe, I return to con- fider the other general caufe of dropfy, which I have faid in (1647.) mav Dc> ^n interruption or diminution of the abforption that fhould take up the exhaled fluids from the feveral cavities and interftices of the body; the caufes of which interruption, however, are not eafily afcertained. 1665.] It feems probable, that abforption may be di- minifhed, and even ceafe altogether, from a lofs of tone in the abforbent extremities of the lymphatics. I cannot indeed doubt that a certain degree of tone or aaive power is neceffary in thefe abforbent extremities; and it appears probable, that the lame general debility which produces that laxity of the exhalant veffels, wherein I have fuppofed the hydropic diathefis to confift, will at the fame time oc- 2ZS P R A C if I C E cafion a lofs of tone in the abk|rbents; and therefore that a laxity of the exhalants will generally beaccompanied with a lofs of tone in the abforbents; and that this will have a fhare in the produaion of dropfy. Indeed it is probable that the diminution of abforption has a confiderable fhare in the matter; as dropfies are often cured by medicines which feem to operate by exciting the action of the abfor- bents. 1666.] It has been fuppofed, that the abforption per- formed by the extremities of lymphatics may be interrupt- ed by an obftruaion of thefe veffels, or at leaft of the con- globate glands throuoh which thefe veffels pafs. This, how- ever, is very doubtful. As the lymphatics have branches frequently communicating with one another, it is not pro- bable that the obftruction of any one, or even feveral of thefe, can have any confiderable effea in interrupting the abforption of their extremities. And for the lame reafon it is as little probable that the obftruaion of conglobate glands can have fuch an effea; at leaft it is only an obftruction of the glands of the mefen- tery, through which fo confiderable a portion ofthe lymph paffes, that can poffibly have the effect of interrupting ab- forption. But even this we fliould not readily fuppofe, there being reafon to believe that thefe glands, even in a confiderably tumefied ftate, are not entirely obftruaed: And accordingly I have known feveral inftances of the moft part ofthe mefenteric glands being confiderably tume- fied, without either interrupting the tranfmiffion of fluids to the blood-velfels, or occafioning any dropfy. An hydropic fwelling, indeed, feems often to affea the arm from a tumour of the axillary gland: but it feems to me doubtful, whether the tumour of the arm may not be owing to fome compreffion of the axillary vein, rather than loan obftruction of the lymphatics. 1667. J A particular interruption of abforption may be fuppofed to take place in the brain. As no lymphatic vef- fels have yet very certainly been difcovered in that organ, it may be thought that the abforption, which certainly takes place there, is performed by the extremities of veins, or by veflels that carry the fluid direaiy into the veins; fo that any impediment to the free motion of the blood in the veins ef the brain, may interrupt the abforption there, and OF PHYSIC. &37 occafion that accumulation of ferous fluid which fo fre- quently occurs from a congeftion of blood in thefe veins. But I give all this as a matter of conjeaure only. 1668.] Having thus explained the general caufes of dropfy, I fhould proceed, in the next place, to mention the feveral parts of the body in which ferous collections take place, and fo to mark the different fpecies of dropfy: But I do not think it neceffary for me to enter into any mi- nute detail upon this fubjea. In many cafes, thefe col- feaions are not to be afcertained by any external fymptoms, and therefore cannot be the objeas of praaice; and many of them, though in fome meafure difcernible, do not feem to be curable by our art. I the more efpecially avoid mentioning very particularly the feveral fpecies, becaufe that has already been fufficiently done by Dr. D. Monro, and other writers, in every body's hands. I muft confine myfelf here to the confideration of thofe fpecies which are the moft frequently occurring and the moft common ob- jeas of our pra6tice; which are, the Anafarca, Hydro- thorax, and Afcites; and each of thefe I fhall treat of in fo many feparate feaions. Sect. I. Of Anasarca. 1669.] THE Anafarca is a fwelling upon the furface ofthe body, at firft commonly appearing in particular parts only, but at length frequently appearing over the whole. So far as it extends, it is an uniform fwelling over the whole member, at firft always foft, and readily receiving the pref- fure of the finger, which forms a hollow that remains for fome little time after the preffure is removed, but at length rifes again to its former fulnefs. This fwelling generally appears, firft, upon the lower extremities: and there too only in the evening, difappearing again in the morning. It is ufually more confiderable as the perfon has been more in an erea pofture during the day; but there are many inftances of the exercife of walking preventing altogether its otherwife ufual coming on. Although this fwelling ap- pears at firft only upon the feet and about the ankles; yet if the caufes producing it continue to aa, it gradually ex- Vol. II. C c 238 PRACTICE tends upwards, occupying the legs, thighs, and trunk of the body, and fometimes even the head. Commonly the fwelling of the lower extremities diminifhes during the night; and in the morning, the fwelling of the face is moft confiderable, which again generally difappears almoft en- tirely in the courfe of the day. 1670.] The terms of Anasarca and Lewcophlegmatia have been commonly confidered as fynonymous; but fome authors have propofed to confider them as denoting dif- tina difeafes. The authors who are of this opinion em- ploy the name of Anasarca for'that difeafe which begins in the lower extremities, and is from thence gradually ex- tended upwards in the manner I have juft now defcribed; while they term Leucophlematia, that in which the fame kind of fwelling appears even at firft very generally over the whole body. They feem to think alfo, that the two difeafes proceed from different caufes;. and that, while the anafarca may arife from the feveral caufes in (1649.— 1660.) the leucophlegmatia proceeds efpecially from a deficiency of red blood, as we have mentioned in (1661. et seq.) I cannot, however, find any proper foundation for this diftinaion. For although in dropfies'proceeding from the caufes mentioned in (1661. et seq.) the difeafe appears in fome cafes more immediately affeaing the whole body; yet that does not eftablifh a difference from the common cafe of anafarca: for the difeafe, in all its circumftances, comes at length to be entirely the fame; and in cafes occa- fioned by a deficiency of red blood, I have frequently ob- ferved it to come on exaaiy in the manner of an anafarca, as above defcribed. 1671.J An anasarca is evidently a preternatural collec- tion of ferous fluid in the cellular texture immediately un- der the fkin. Sometimes pervading the fkin itfelf, it oozes out through the pores of the cuticle; and fometimes, too grofs to pafs by thefe, it raifes the cuticle in blifters. Sometimes the fkin, not allowing the water to pervade it, is compreffed and hardened,, and at the fame time fo much diftended, as to give anafarcous tumours an unufual firm- nefs. It is in thefe laft circumftances alfo that an erythe- matic inflammation is ready to come upon anafarcous fwellings. 1672. J An anafarca may immediately arife from any o£ OF PHYSIC. 339 The feveral caufes of dropfy which aa more generally up- on the fyftem: And even when other fpecies of dropfy, from particular circumftances, appear firft; yet whenever ■thefe proceed from any caufes more generally affeaing the fyftem, an anafarca fooner or later comes always to be joined with them. 1^73-] The manner in which this difeafe commonly firft -appears, will be readily explained by what I have faid in {11651.) refpeaing the effeas of the pofture ofthe body. lis gradual progrefs, and its affeaing, after fome time, not only the cellular texture under the fkin, but probably alfo much of the fame texture in the internal parts, will be underftood partly from the communication that is readily made between the feveral parts of the cellular .texture ; but efpecially from the fame general caufes of the difeafe producing their effeas in every part of the body. It ap- pears to me, that the wrater of anafarcous fwellings is more readily communicated to the cavity of the thorax, and to the lungs, than to the cavity of the abdomen, or to the vifcera contained in it. - 1674. J An anafarca is almoft always attended witha fcarcity of urine; and the urine voided, is, from its fear- city, always of a high color; and from the fame caufe, after cooling, readily lets fall a copious reddifh fediment. This fcarcity of urine may fometimes be owing to an ob- ftruaion of the kidneys; but probably is generally occa- fioned by the watery parts of the blood running off into the ^cellular texture, and being thereby prevented from pafling •in the ufual quantity to the kidneys. The difeafe is alfo generally attended with an unufual degree of thirft ; a circumftance I would attribute to a like abftraaion of fluid from the tongue and fauces, which are extremely fenfible.to every diminution ofthe fluid in thefe parts. 1675.] The cure of anafarca is*o be attempted upon three general indications. 1. The removing the remote caufes of the difeafe. 2. The evacuation of the ferous fluid already colleaed in the cellular texture. 3. The reftoring the tone of the fyftem,, the lofs of which may be confidered in many cafes as the proximate caufe of the difeafe. 240 PRACTICE 1676.] The remote caufes are very often fuch as had not only been applied, but had alfo been removed* long before the difeafe came on. Although, therefore, their ef- feas remain, the caufes themfelves cannot be the objeas of praaice; but if the caufes ftill continue to be applied, fuch as intemperance, indolence, and fome others, they muft be removed. For the moft part, the remote caufes are certain difeafes previous to the dropfy, which are to be cured by the remedies particularly adapted to them, and cannot be treated of here. The curing of thefe, indeed, may be often difficult; but it was proper to lay down the prefent indication, in order to fhow, that when thefe re- mote caufes cannot be removed, the cure of the dropfy muft be difficult, or perhaps impoffible. In many cafes, therefore, the following indications will be to little pur- pofe; and particularly, that often the execution of the fe- cond will not only give the patient a great deal of fruitlefs trouble, but commonly alfo hurry on his fate. 1677.J The fecond indication for evacuating the col- leaed ferum, may be fometimes executed with advantage, and often, at leaft, with temporary relief. It may be per- formed in two ways. Firft, by drawing off the water di- rectly from the dropfical part, by openings made into it for that purpofe: Or, fecondly, by exciting certain ferous excretions; in confequence of which, an abforption may be excited in the dropfical parts, and thereby the ferum abforbed and carried into the blood-veffels may afterwards be direaed to run out, or may fpontaneoufly pafs out, by one or other of the common excretions. 1678.J In an anafarca, the openings into the dropfical part are commonly to be made in fome part of the lower extremeties; and will be moft properly made by many finall punaures reaching the cellular texture. Formerly, confiderable incifions were employed for this purpofe: but as any wound made in dropfical parts, which, in order to their healing, muft neceffarily inflame ahd fuppurate, are liable t to become gangrenous; fo it is found to be much fafer to make the openings by fmall punaures only, which may heal up by the firft intention. At the fame time, even with refpecl to thefe punaures, it is proper to obferve, that * Thefe are large evacuations of different kinds, but efpecially hemorrhagies, which have ceafed before the dropfy came on. f Peculiarly liable in this di&afe on account of the dirainUhed tone, and couiequently the dinurulhed ft.-engt± of the parts. ™ OF PH'iSIC. /. 11 they fhould be made at fome diftance from one another, and that care fhould be taken to avoid making them in the moft depending parts. 1679.] The water of anafarcous limbs may be fome- times drawn off by pea-iffues, made by cauftic a little be- low the knees: for as the great fwelling of the lower ex- tremities is chiefly occafioned by the ferous fluid exhaled into the upper parts conftantly falling down to the lower; fo the iffues now mentioned, by evacuating the water from thefe upper parts, may very much relieve the whole ofthe difeafe. Unlefs, however, the iffues be put in before the difeafe is far advanced, and before the parts have very much loft their tone, the places of the iffues are ready to become affeaed with gangrene. Some praaical writers have advifed the employment of fetons, for the fame purpofe that I have propofed iffues; but I apprehend, that fetons will be more liable than iffues to the accident juft now mentioned. 1680.] For the purpofe of drawing out ferum from anafarcous limbs, blifters have been applied to them, and fometimes with great fuccefs; but the bliftered parts are ready to have a gangrene come upon them. Bliftering is therefore to be employed with great caution ; and perhaps only in the circumftances that I have mentioned above to be fit for the employment of iffues. 1681.] Colewort-leaves applied to the flan, readily oc- cafion a watery exfudation from its furface; and applied to the feet and legs affeaed with anafarca, have fometimes drawn off the water very copioufly, and with great advantage. Analogous, as I judge, to this, oiled iilk-hofe put upon the feet and legs, fo as to fhut out all communication with the external air, have been found fometimes to draw a quantity of water from the pores of the fkin, and are faid in this way to have relieved anafarcous fwellings; but in feveral trials made, I have never found either the applica- tion of thefe hofe, or that of the colewort-leaves, of much fervice.* 1682.] The fecond means propofed in (1677.) for drawing off the water from dropfical places, may be the em- ployment of emetics, purgatives, diuretics, or fudcnfics. 1683.J As fpontaneous vomiting has fometimes . xe:'ed « Hew doss tliis l»lt agree wi;h the firft fentence of tLi> article I £*: PRACTICE an abforption in hydropic parts, and thereby drawn off the waters lodged in them, it is reafonable to fuppofe that vo- miting excited by art may have the fame effea; and ac- cordingly it has been often practifed with advantage. The praaice, however, requires that the ftrong antimonial eme- tics be employed, and that they be repeated frequently af- ter fhort intervals. 1684. J Patients fu limit more readily to the ufe of pur- gatives, than to that of emetics; and indeed they common- ly bear the former more eafily than the latter. At the fame time, there are no means wc can employ to procurea copious evacuation of ferous fluids with greater certainty than the operation of purgatives, and it is upon thefe ac- counts that purging is the evacuation which has been moft frejq wmlv^euid perhaps with moft fuccefs, employed in ^lrop"tp*-^Tnas been generally found neceffary to employ ~p.urgai.ives of the more draftic kind; which are commonly known, and need not be enumerated here.t I believe, in- deed, that the more draftic purgatives are the moft effeaual for exciting abforption, as their ftimulus is moft readily communicated to the other parts ofthe fyftem; but of late an opinion has prevailed, that fome milder purgatives may be employed with advantage. This opinion has prevailed particularly with regard to the cryitals vulgarly called the Cream of Tartar, which in large dofes, frequently repeat- ed, have fometimes anfwered the purpofe of exciting large evacuations both by ftool and urine, and has thereby cured dropsies. This medicine, however, has frequently failed, + The Draftic purgatives arc Jalap, Colycynth, Gambogc^Scaremony, Src. Their Draftic quality however, depends very much on the dofe in which they ..re given, ("mail dofes being gently laxative, while large ones are very violent in their operation. Tney ought feldom to he given alone, but in •conjunction with fome aromatic, which greatly increafes their action, and at the fame time prevents the UT.ea'nefs of griping, with which their operation is frequently attended : molt of thefe drattict being relinous fubftances, they are difficultly fallible in tire alimentary canal, or if reduced to a pow- der they are liable to concrete ; in cither cafe their action is impeded. To remedy thefe inconveni- >encies, it is ufual to add to them fotne fait, which both divides the relin and prevents its concretion ; r.nd confequently increafes its action. For thefe reafons, we find in the fhops manv formulx, in which the draftee refins are mixed with either falts or aromatics, or both: As, the Pulvis Alretiors, Pulvis e Scammonio compofitus, Pulvis e Scammoniorurn Aloe, Pulvls e fenna compofitus, and Hec- tnarium e Scammonio ofthe London Pharmacopxia; and, the Pulvis e Jalappa compofitus, Pulvis c cc.immonio ccmpolitus Pilulx Alceticse, Pilulae ex colocynthide cum Alee, Pilulae, e Jalappa, and I'ilulse Rufi of the Edinburgh Pharmacopccia. Any of the foregoing coaipofition% it given in fufficient dofes, are very active and brilk purges. Many more might be contrived, and on fome occafioiv ^ia.y be nrcelfary. For procuring a brilk dif- charge of fluids, an addition of Calomel is remarkably effkaciou.,, as in the following formulx: R. Scammon. Calomel. Crem. Tart. Zinzib aa. p. a?. M. f. Pulv.

OF PHYSIC. 2*3 both in its operation and effects, when the draftic purga- tives have been more fuccefsful. Practitioners have long ago obferved, that, in the em- ployment of purgatives, it is requifite they be repeated af- ter as fhort intervals as the patient can bear; probably for this reafon, that when the purging is not carried to the de- gree of foon exciting an abforption, the evacuation weakens the fyftem, and thereby increafes the afflux of fluids to the hydropic parts. 1685. ) The kidneys afford a natural outlet for a great part of the watery fluids contained in the blood-veffels; and the increafing the excretion by the kidneys to a confi- derable degree, is a means as likely as any other of exciting an abforption in dropfical parts. It is upon this account that diuretic medicines have been always properly employ- ed in the cure of dropfy. The various diuretics that may be employed, are enumerated in every treatife of the Ma- teria Medica and of the Practice of Phyfie, and therefore need not be repeated here. It happens, however, unluck- ily, that none of them are of very certain operation; nei- ther is it well known why they fometimes fucceed, and why they fo often fail; nor why one medicine fliould prove of fervice when another does not.. It has been generally the fault of writers upon the Practice of Phyfie, that they give us inftances of cafes in which certain medicines have proved very efficacious, but neglecl to tell us in how many inftances the fame have failed. 1686.J Itdeferves to be particularly obferved here, that there is hardly any diuretic more certainly powerful than a large quantity of common water taken in by drinking. I have indeed obferved above in (1659.; tnat a *ar§e qua- lity of common water, or of watery liquors taken in by drinking, has fometimes proved a caufe of dropfy; and practitioners have been formerly fo much afraid that watery liquors taken in by drinking might run off into the dropfi- cal places and increafe the difeafe, that they have generally enjoined the abftaining, as much as poffible, from fuch li- quors. Nay, it has been further aliened, that by avoiding this fupply of exhalation, and by a total abftinence from drink, dropfies have been entirely cured. What conclu- fion is to be drawn from thefe facts, is however, very doubt- ful. A dropfy arifing from a large quantity of liquids ta- tU "PRACTICE ken into the body, has been a very rare occurrence; and there are, on the other hand, innumerable inftances of very large quantities of water having been taken in and running off again very quickly by ftool and urine, without produc- ing any degree of dropfy. With refpecl to the total ab- ftinence from drink, it is a practice of the moft difficult execution; and therefore has been fo feldom pra£tifed, that we cannot poffibly know how far it might prove effec- tual. The practice of giving drink very fparingly, has in- deed been often employed: but in a hundred inftances I have feen it carried to a great length without any manifeft advantage; while, on the contrary, the practice of giving drink very largely has been found not only fafe, but very often eff'cftual in curing the difeafe. The ingenious and learned Dr. Millmanhas, in my opinion, beencommendably employed in reftoring the praQice of giving large quanti- ties of watery liquors for the cure of dropfy. Not only from the inftances he mentions from his own practice, and from that of feveral eminent phyficians in other parts of Europe, but alfo from many inftances in the records of phyfie, of the good effefts of drinking large quantities of mineral waters in the cure of dropfy, I can have no doubt ofthe practice recommended by Dr. Millman being very often extremely proper. I apprehend it to be efpecially adapted to thofe cafes in which the cure is chiefly attempt- ed by diuretics. It is very probable that thefe medicines can hardly be carried in any quantity to the kidneys with- out being accompanied with a large portion of water; and the late frequent employment of the cryftals of tartar has often fhown, that the diuretic efFerita. of that medicine* are almoft only remarkable when accompanied with a large quantity of water; and that without this, the diuretic effects of the medicine feldom appear. I fliall conclude this fubject with obferving, that as there are fo many cafes of dropfy abfolutely incurable, the prac- tice now under confideration" may often fail, yet in moft cafes it may be fafely tried; and if it appear that the water taken in pades readily by the urinary fecretion, and efpeci- ally that it increafes the urine beyond the quantity^of drink taken in, the practice may probably he continued w-ith great advantage: but, on the contrary, if the urine be not increa f- cd, or be not even in proportion to the drink taken in. it OF PHYSIC. ' 245 may be concluded, that the water thrown in runs off by the exhalants, and will augment the difeafe. »687.] Another fet of remedies which may be employ- ed for exciting a ferous excretion, and thereby curing dropfy, is that of fudorifics. Such remedies, indeed, have been fometimes employed; but however ufeful they may have been thought, there are few accounts of their having effected a cure; and although I have had fome examples of their fuccefs, in moft inftances of their trial they have been ineffectual. Upon this fubject it is proper to take notice ofthe fever- al means that have been propofed and employed for difli- pating the humidify ofthe body; and particularly that of heat externally applied to the furface of it. Of fuch ap- plications I have had no experience; and their propriety and utility muft reft upon the credit of the authors who re- late them. I fhall offer only this conjecture upon the fub- ject: That if fuch meafures have been truly ufeful, as it has feldom been by the drawing out of any fenfible humid- ity, it has probably been by their reftoring the perfpiratiorj, which is fo often greatly diminifhed in this difeafe; or, per- haps, by changing the ftate of the ,fkin, from the imbibing condition which is alledged to take place, into that of pert- piring. 1688.] When, by the feveral means now mentioned, we fhall have fucceeded in evacuating the water of dropfies, there will then efpecially be occafion for our third indica- tion ; which is, to reftore the tone qf the fyftem, the lofs of which is fo often the caufe of the difeafe. This ^indica- tion, indeed, may properly have place from; die very firft appearance of the difeafe; and certain meafu?es adapted to this purpofe may, upon fuch firft appearance, be em- ployed with advantage. In .many cafes of a moderate dif- eafe, I am perfuaded that they may obviate any future increafe of it. 1689. J Thus, upon what is commonly the firft fymp- toms of anafarca, that is, upon the appearance of what are called Oedematous Swellings of the feet and legs, the three remedies of bandaging, friction, and exercife, have often been ufed with advantage. 1690.] That fome degree of external compreffion is Vol. 11. H k 246 PRACTICE fuited to fupport the tone of the veffels, and particularly to prevent the effects of the weight of the blood in dilating thofe of the lower extremities, mult be fufficiently evident; and the giving that compreffion by a bandage properly ap- plied, has been often ufeful. In applying fuch a bandage, care is to be taken that the compreffion may never be great- er on the upper than on the lower part ofthe limb; and this, I think, can hardly ever be fo certainly avoided, as by employing a properly conftructed laced flocking. 1691.] Friction is another means by which the action of the blood-veffels may be promoted, and thereby the ftag- nation of fluids in their extremities prevented. According- ly, theufe ofthe flefh-brufh has often contributed to difcufs cedematous fwellings. It appears to me, that friction, for the purpofes now mentioned, is more properly employed in the morning, when the fwelling is very much gone off, than in the evening, when any confiderable degree of it has already come on. I apprehend alfo, that friction being made from below upwards only, is more ufeful than when made alternately upwards and downwards. It has been common, inftead of employing the flefh-brufh, to make friction by warm and dry flannels; and this may in fome cafes be the moft convenient: but I cannot perceive that the impregnation of thefe flannels with certain dry fumes is of any benefit. 1692.] With refpect to exercife, I muft obferve, that although perfons being much in an erett pofture during the day, may feem to increafe the fwelling which comes on at night; yet as the action of the mufcles has a great fhare in promoting the motion of the venous blood, fo I am certain, that as much exercife in walking as the patient can eafily bear, will often prevent that cedematous fwelling, w'hich much ftanding, and even fitting, would have brought on. 1693.] Thefe meafures, however, although they may be ufeful at the coming on of a dropfy, whofe caufes are not very powerful, will be often infufficient in a more vio- lent difeafe; and fuch therefore will require more power- ful remedies. Thefe are, exercife and tonic medicines; which may be employed both during the courfe of the dif- eafe and efpecially after the water has been evacuated. 1694.J Exeroife is fuited to affift in every function of the animal ceconomyj particularly to promote perfpiration, OF PHYSIC. *47 and thereby prevent the accumulation of watery fluids in the body. I apprehend alfo, that it may be the moft ef- fectual means for preventing the fkin from being in an im- bibing ftate; and, as has been hinted above on the fubject of Emaciation^ 1608.) I am perfuaded, that a full and large perfpiration will always be a means of exciting- abforption in every part of the fyftem. Exercife, there- fore, promifes to be highly ufeful in dropfy; and any mode of it may be employed that the patient can moft con- veniently admit of. It fhould, however, always be as much as he can eafily bear: and in anafarca, the fhare" which the exercife of mufcles has in promoting the motion of the ve- nous blood, induces me to think that bodily exercife, to whatever degree the patient can bear it, will always be the molt ufeful. From fome experience alfo, I am perfuaded, that by exercife alone, employed early in the difeafe, many droplies may be cured. 1695.] Befides exercife, various tonic remedies are pro- perly employed to reftore the tone ofthe fyltem. The chief of thefe are, chalybeates, the Peruvian bark, and various bitters. Thefe are not only fuited to reftore the tone of the fyftem in general, but are particularly ufeful in ftrengthen- ing the organs of digeftion, which in dropfies are frequent- ly very much weakened; and for the fame purpofe alfo aromatics may be frequently joined with the tonics. 1696.] Cold bathing is upon many occafions the moft powerful tonic we can employ; but at the beginning of dropfy, when the debility of the fyftem is confiderable, it can hardly be attempted with fafety. After, however, the water of dropfies lias been very fully evacuated, and the indication is to ftrengthen the fyftem for preventing a re- lapfe, cold bathing may perhaps have a place. It is, at the fame time, to be admitted with caution; and can fcarce- ly be employed till the fyftem has otherwife recovered a good deal of vigour. When that indeed has happened, cold bathing may be very ufeful in confirming and com- pleting it. 1697. J In perfons recovering from dropfy, while the fe- veral means now mentioned for ftrengthening the fyftem are employed, it will be proper at the fame time .ta keep conftantly in view the fupport of the wratery excretions.; and confequently the keeping up the perfpiration by a great 243 PRACTICE deal of exercife, and continuing the full flow of the urina- ry excretion by the frequent ufe of diuretics. ---—»©<■■--- Sect. II. Of the Hydrothorax or Dropsy of the Breast. 1698.] THE preternatural collection of ferous fluid in the thorax, to which we give the appellation of Hydrotho- rax, occurs more frequently than has been imagined. Its prefence, however, is not always to be very certainly known; and it often takes place to a confiderable degree before it be difcovered. 1699.] Thefe collections of watery fluids in the thorax* ate found in different fituations. Very often the water is found at the fame time in both facs of the pleura, but fre- quently it? one of them only. Sometimes it is found in the pericardiuLi alone; but for the moft part it only appears there when at the fame time a collection is prefent in one or both cavities of the thorax. In fome inftances, the col- lection is found to be only in that cellular texture of the lungs which furrounds the bronchiae, without there being at the fame time any effufion into the cavity of the thorax. Pretty frequently the water collected confifts chiefly of a great number of hydatides in different fituations; fome- times feemingly floating into the cavity, but frequently connected with and attached to particular parts of the inter- nal furface of the pleura. 170x3.] From the collection of water being thus in vari- ous fituations and circumftances, fymptoms arife which are different in different cafes; and from thence it becomes of- ten difficult to afcertain the prefence and nature of the af- fection. I fhall, however, endeavor here to point out the moft common fymptoms, and efpecially thofe of that prin- cipal and moft frequent form of the difeafe, when the fe- rous fluid is prefent in both facs of the pleura, or, as we ufually fpeak, in both cavities of the thorax. 1701. J The difeafe frequently comes on with a fenfe of anxiety about the lower part of the fternum. This, before it has fubfifted long, comes to be joined with fome difficul- ty of breathing ; which at firft appears only upon the per- fon's moting a little falter than ufual, dpon his talking up OF PHYSIC. 249 sm acclivity, or upon his afcending a ftaircafe: But after fome time, this difficulty of breathing becomes more con- ftant and confiderable, efpecially during the night, when the body is in a horizontal fituation. Commonly, at the fame time, lying upon one fide is more eafy than upon the other, or perhaps lying upon the back more eafy than upon either fide. Thefe circumftances are ufually attended with a fre- quent cough, that is at firft dry; but which, after fome time, is accompanied with an expectoration of this mucus. With all thefe fymptoms, the hydrothorax is not certain- ly difcovered, as the fame fymptoms often attend other dif. eafes of the breaft. When however, along with thefe fymp- toms there is at the fame time an cedematous fwelling of the feet and legs, a leucophlegmatic palenefs of the face, and a fcarcity of urine, the exiftence of a hydrothorax can be no longer doubtful. Some writers have told us, that fometimes in this difeafe, before the fwelling of the feet comes on, a watery fwelling ofthe ferotum appears; but I have never met with any inftance of this. 1702. J Whilft the prefence of the difeafe is fomewhat uncertain, there is a fymptom which fometimes take place, and has been thought to be a certain characteriftic of it; and that is, when foon after the patient has fallen afleep, he is fuddenly awaked with a fenfe of anxiety and difficult breathing, and with a violent palpitation of the heart. Thefe feelings immediately require an erect pofture; and very often the difficulty of breathing continues to require and to prevent fleep for a great part of the night. This fymptom I have frequently found attending the difeafe: but I have alfo met with feveral inftances in which this fymptom did not appear. I muft remark further, that I have not found this fymptom attending the empyema, or any other difeafe ofthe thorax; and therefore, when it attends a difficulty of breathing, accompanied with any the fmalleft fymptom of • dropfy, I haveliad no doubt in concluding the prefence of water in the cheft, and have always had my judgment con- firmed by the fymptoms which afterwards appeared. 1703.] The hydrothorax often occurs with very few, or almoft none, ofthe fymptoms above-mentioned; and is hot, therefore, very certainly difcovered till fome ethers appear. The moft decifive fymptom is a fluctuation of water in the cheft, perceived by the patient himfelf, Or by 250 PRACTICE the phyfician, upon certain motions of the body. How far the method propofed by Aucnbrugger will apply to af- certain the prefence of water and the quantity of it in the cheft, I have not had occafion or opportunity to obferve. It has been faid, that in this difeafe fome tumour appears upon the fides or upon the back, but I have not met with any inftance of this. In one inftance of the difeafe, I found one fide ofthe thorax confiderably enlarged, the ribs itand- ing out farther on that fide than upon the other. A numbnefs and a degree of palfy in one or both arms, has been frequently obferved to attend a hydrothorax. Soon after this difeafe has made fome progrefs, the pulfe commonly becomes irregular, and frequently intermitting: but this happens in fo many other difeafes of the breaft, that, unlefs when it is attended with fome other ofthe above- mentioned fymptoms, it cannot be confidered as denoting the hydrothorax. 1704.] This difeafe, as other dropfies, is commonly at- tended with thirft and a fcarcity of urine, to be explained in the fame manner as in the cafe of anafarca (1674.) The hydrothorax, however, is fometimes without thirft, or any other febrile fymptom; although I believe this happens in the cafe of partial affections only, or when a more general affedion is yet but in a flight degree. In both cafes, how- ever, and more efpecially when the difeafe is confiderably advanced, fome degree of fever is generally prefent: and I apprehend it to be in fuch cafe, that the perfons affected are more than ufually fenfible to cold, and complain of the coldnefs ofthe air when that is not perceived by other perfons. 1705.] The hydrothorax fometimes appears alone, with- out any other fpecies of dropfy being prefent at the fame time: and in this cafe the difeafe, for the moft part, is a partial affection, as being either of one fide of the thorax only, or being a collection of hydatides in one part of the cheft. The hydrothorax, however, is very often a part of ' more univerfal dropfy, and when at the fame time there is water in all the three principal cavities and in the cellular texture of a great part of the body. I have met with fe- veral inftances in which fuch univerfal dropfy began firft by an effufion into the thorax. The hydrothorax, however, more frequently, comts on from an anafarca gradually in- creafing; and, as I have faid above, the general diathefis 0 F PH Y S 1C. 251 feems often to affect the thorax fooner than it does either the head or the abdomen. 1706.] This difeafe feldom admits of a cure, or even of alleviation, from remedies. It commonly proceeds to give more and more difficulty of breathing, till the action of the lungs be entirely interrupted by the quantity of water ef- fufed; and the fatal event frequently happens more fud- denly than was expected. In many of the inftances of a fatal hydrothorax, I have remarked a fpitting of blood to come on feveral days before the patient died. 1707.J The caufe of hydrothorax is often manifeftly one or other of the general caufes of dropfy pointed out above: but what it is that determines thefe general caufes to act more efpecially in the thorax, and particulaily what it is that produces the partial collections that occur there, I do not find to be eafily afcertained. 1708.] From what has been faid above, it will be evi- dent, that the cure of hydrothorax muft be very much tlie fame with that of anafarca; and when the former is joined with the latter as an effect of the fame general diathefis, there can be no doubt of the method of cure being the fame in both. Even when the hydrothorax is alone, and the difeafe partial, from particular caufes acting in the tho- rax only, there can hardly be any other meafures employ- ed, than the general ones propofed above. There is only one particular meafure adapted to the hydrothorax; and that is, the drawing off the accumulated waters bv a para- centefis ofthe thorax. 1709.J To what cafes this operation may be moft pro- perly adapted, I find it difficult to determine. That it may be executed with fafety, there is no doubt; and that it has been fometimes practifed with fuccefs, feems to be very well vouched.* When the difeafe depends upon a general hydropic diathefis, it cannot alone prove a cure, but may give a temporary relief; and when ether remedies # la the memoirs of the Academy of Sciences at Paris, for 1703, M. De Verney relates ihs cafeef a woman who had both an Afcites and Hydrothorax. He firft emptied the abdomen by tapping, anj?; a few davs afterwards he pierced the thorax with a trochar, near to the (pine, between the t=:o$i. and third falfe ribs; by which opening he drevr orf a conilderable quantity of water: the operation jave immediate relief to the patient, and (he was able to return to her ordinary employment**! about a month's time.—Biarichi alfo relates a fuccefofu! operation of tapping the thorax; but te feems to be timid in his practice, and confeiies that he h.-.s feldom v-jnttyred on the 0jw.1t' jr..— The practice of evacuating water contained in the thorax by an incifi< 'i is very old.

Sect. III. Of Aicites, or,Dropsy of the Lower Belly. 1710.3 THE name of Ascites is given to every collec- tion of waters canting a general fwelling and diftention of the lewerheHy; and fuch collections are more frequent than thofe which happen in the thorax. - 171.1.. J The -collections in the lower belly, like thofe of the thorax, are found in different fituations. Moft com- monly they are in the fac of the peritonaeum, or general cavity of the abdomen: 'but they often begin by facs form- ed upon, arid connected with, one or other of the vifcera; and perhaps the moft frequent inftances of this kind occur in the ovaria of females. Sometimes the water of afcites is found entirety without the peritonaeum, and between this and the abdominal mufcles. 1712.) Thefe collections connected with particular vif- cera, and thofe formed without the peritonaeum, form that difeafe which; authors have termed the encysted dropsy, or hydrops saccaiks. Their precife feat, and thek exiftence, is Very often difficult to be afcertained. They are gen<&saily formed bycorte&ions of hydatides. 1713.] In the moft ordinary cafe, that of abdominal dropfy, the fwelling at firft is in forme meafure over die whole fcelly, but generally appears moft confiderable in theepi- gamium. As the difeafe, however, advances, the fwelling becomes more uniform over the whole. The diftention, and fenfe of weight, though cflwfiderable, vary a little ac- cording as the pofture of the body isTchanged ; the weight being felt the moft upon the fide on which the ptaiient lies, while at the fame time on the oppofite fide the diftention becomes fomewhat'fefs. In almoft all the inftances of af- cites, the fluctuation^©f the water within, may be perceived by the practitioner's feeling, and fometimes by his hearing. This perception of fluctuation does not certainly diftinglifh Or PHYSIC. 25* the different ftates of dropfy; but ferves very well to dif- tinguifh dropfy from tympanites, from cafes of phyfeonia, and from the ftate of pregnancy in women. 1714.] As afcites frequently occurs when no other fpe* cies of dropfy does at the fame time appear; but fometimes the afcites is a part only of univerfal dropfy. In this cafe, it ufually conies on in confequence of an anafarca, gra- dually increafing; but its being joined with anafarca, does not always denote any general diathefis, as for the moft part an afcites fooner or later occafions cedematous fwellings of the lower extremities. When the collection of water in the abdomen, from whatever caufe, becomes confiderable, it is always attended with a difficulty of breathing; but this fymptom occurs often when, at the fame time, there is no water in the thorax. The afcites is fometimes unaccompa- nied with any fever; but frequently there is more or lefs of fever prefent with it. This difeafe is never confiderable, without being attended with thirft and fcarcity of urine. 1715. J In the diagnofis of afcites, the greateft difficulty that occurs, is in difcerning when the water is in the cavity of the abdomen, or when it is in the different ftates of en* cyfted dropfy above-mentioned. There is, perhaps, no cer- tain means of afcertaining this in all cafes; but in many we may attempt to form fome judgment with regard to it. When the antecedent circumftances give fufpicion of a general hydropic diathefis; when at the fame time fome degree of dropfy appears in other parts ofthe body; and when, from its firft appearance, the fwelling has been equal- ly over the whole belly, we may generally prefume that the water is in the cavity of the abdomen. But when an af- cites has not been preceded by any remarkable cachectic ftate of the fyftem, and when at its beginning the tumour and tenfion had appeared in one part of the belly more than another, there is reafon to fufpect an encyfted dropfy. Even when the tenfion and tumour of the belly have be- come general and uniform over the whole; yet if the fyf- tem ofthe body in general appear to be little affected; if the patient's ftrength be little impaired; if the appetite con- tinue pretty entire, and the natural fleep be little interrupt- ed ; if the menfes in females continue to flow as ufual; if there be yet n© anafarca; or, though it may have already t0L. II. I 1 :^4 practicl taken place, if it be ftill confined to the lower extremities',. aj^d there be no leucophlegmatic palenefs or fallow colour in the countenance; if there be no fever, nor fo much' thirft, or fcarcity of urine, as occur in a more general affec- tion ; then, according as more of thefe different circum- ftanees take place, there will be the ftronger ground for fuppofing the afcites to be of the encyfted kind. The chief exception to be made from this as a general rule, will, in my opinion, be when the afcites may with much probability, be prefumed to have come on in confe- quence of a fcirrhous liver; which, I apprehend, may oc- cafion a collection of water in the cavity of the abdomen, while the general fyftem of the body may not be otherwife much affected. 1716.] With refpect to the cure of afeftes when of the encyfted kind, it.does.not, fo far as I know, admit of any. When the collection of water is in the abdominal cavity alone, without any other fpecies of dropfy prefent at the fame time, I apprehend the afcites will always be of diffi- cult cure; for it may be prefumed to depend upon a feir- rhofity of the liver, or other confiderable affection of the abdominal vifcera, wrhich I conceive to be of very difficult cure, and therefore the afcites depending upon them. At the fame time, fuch cafes may often admit of a temporary relief by the paracentefis. 1717.] When the afcites is apart of univerfal dropfy, it may, as far as other cafes of that kind can, admit of a cure; and it will be obvious, that fuch a cure muft be ob- tained by the fame means as above propofed for the cure of general anafarca.* It frequently happens that the afcites is attended with a diarrhoea; and, in that cafe, does not admit of the ufe of purgatives fo freely as cafes of anafarca commonly do. It is therefore often to be treated by diuretics almoft alone. The diuretics that may be employed, are chiefly thofe above mentioned; but in afcites, a peculiar one has been found out. It is a long-continued gentle friction ofthe fkin over the whole of the abdomen, by the fingers dipped in oil. This has fometimes been ufeful in exciting an in- creafed flow of urine; but in moft of the trials of it which I have known made, it has failed in producing that effect. * Sec the notes on article 1664. O F P H Y S I C. 255 1718.] The afcites admits of a particular means for im- mediately drawing off the collected waters: and that is the well-known operation ofthe paracentefis of the abdomen. In what circumftances of afcites this operation can riioft properly be propofed, it is difficult to determine; but, fo far as I can judge, it muft be regulated by very much the fame confiderations as thofe above-mentioned with regard to the paracentefis of the thorax. The manner of performing the paracentefis of the abdo- men, and the precautions to be taken with refpect to it, are now fo commonly known, and delivered in fo many books, that it is altogether unneceffary forme to offer any direc- tions upon that fubject here; efpecially after the full and judicious information and directions given by Mr. Bell, in the fecond volume of his System of Surgery. CHAP. IV. £>f General ^toelitnpf, ARISING FROM AN INCREASED BULK OF THE WHOLE SU^SfANCE OF PARTICULAR PARTS. 1719.] LJ PON the fubjects of this chapter, feveral no- fological difficulties occur,, and particularly.with refpect to admitting the Physconva into the order of General Swel- lings. At prefent, however, it is not neceffary forme todifcufs this point, as I am here to omit entirely the confideration of Phyfconia; both becaufe it can feldom admit of any fuccefs- ful practice,and becaufe I cannot deliverany thing ufefulei- ther withregard to the pathology or practice in fuch a difeafe. 1720.] The only other genus of difeafe comprehended under the title of the prefent chapter, is the Rachitis; and this being both a proper example ofthe clafs of Cachexy, and of the order of Intumesccntice or General Swellings, I fliall offer fome obfervations with regard to it. Of RACHITIS, or RICKETS. 1721.] THIS difeafe has been fuppofed to have appear- ed only in modern times, and not above two hundred years ago. This opinion, notwithstanding it has been maintained by perfons of the moft refpectable authority,* appears to * Boerhaave was of this opinion, See Van Swielca's Commentary on AphorUffi 148a. »»6 PRACTICE me, from many confiderations^ improbable ; but it is a point of two litde confequence to detain my readers here. The only application of it which defervcs any notice is, that it has led to a notion of the difeafe having arifen from the lues venerea, which had certainly made its firft appear*- ance in Europe not very long before the date commonly affigned for the appearance of rachitis : But I fhall hereaf- ter fhow, that the fuppofed connection between the Siphy- lis and Rachitis is without foundation.t 1722.] In delivering the hiftory of the Rickets, I muft, in the firft place, obferve, that with refpect to the antece- dents of the difeafe, every thing to be found in authors up- on this fubject, appears to me to reft upon a very uncertain foundation. In particular, with refpect to the ftate ofthe parents whofe offspring become affected with this difeafe, I have met with many inftances of it, in children from feem- ingly healthy parents, and have met likewife with many in- ftances of children who never became affected with it, al- though born of parents who, according to the common ac- counts, fhould have produced a rickety offspring : So that even making allowance for the uncertainty of fathers, I do not find the general opinion of authors upon this fubject to be properly fupported. 1723.] The difeafe, however, may be juftly confidered as proceeding from parents ; for it often appears in a great number of the fame family : And my obfervation leads jne to judge, that it originates more frequently from mo- thers than from fathers. So far as I can refer the difeafe of the children to the ftate of the parents, it has appeared to me moft commonly to arife from fome weaknefs, and pretty frequently from a fchropbulous habit in the mother, To conclude the fubject, I muft remark, that in many ca- fes I have not been able to difcern the condition of the pa- rents, to which I could refer it. When nurfes, other than the mothers, have been employ- ed to fuckle children, it has been fuppofed that fuch nurfes have frequently given occafion to the difeafe :J and when nurfes have both produced and have fuckled children who became rickety, there may be ground to fufpect their hav- ing occafioned the difeafe in the children of other perfons: But I have had few opportunities of afcertaining this mat- t See Artkte 17*8. t Thi««pi»ion was held by Boerhaave, and notyrtthftandine what tkc Autfer fay* at UK CWl Of tfiU fwagrajA, the ofttiog h certainly foaiiacd on experience? OF PHYSIC. 257 ter. It has in fome meafure appeared to me, that thofe nurfes are moft likely to produce this difeafe, who give in- fants a large quantity of very watery milk, and who conti- nue to fuckle them longer than the ufual time. Upon the whole, however, I am of opinion, that hired nurfes feldom occafion the difeafe, unlefs when a predifpofition to it has proceeded from the parents. 1724. With regard to the other antecedents, which have been ufually enumerated by authors as the remote caufes of this difeafe, I judge the accounts given to be extremely fal- lacious; and I am very much perfuaded, that the circum- ftances in the rearing.of children, have lefs effect in prou ducing rickets than has been imagined. It is indeed not unlikely, that fome of thefe circumftances mentioned as re* mote caufes may favor, while other circumftances may re- fift, the coming on of the difeafe ; but at the fame time, I doubt if any of the former would produce it where there was no predifpofition in the child's original conftitution. This opinion of the remote caufes, I have formed from obi ferving, that the difeafe comes on when none of thefe had been applied; and more frequently that many of them had been applied without occafioning the difeafe. Thus the learned Zevi an i alleges, that the difeafe is produced by an acid from the milk with which a child is ferjifor the firft nine months of its life: But almoft all children are fed with the fame food, and in which alfo an acid is always produc- ed; while at the fame time, not one in a thbufand of the infants fo fed becomes affected with the rickets. If, there- fore, in the infants who become affeQed with this difeafe, a peculiarly noxious acid is produced, we muft feek for fome peculiar caufe of its production, either in the quality of the milk, or in the conftitution of the child; neither of which however, Mr. Zeviani has explained. I cannot indeed be- lieve that the ordinary acid of milk has any fhare in pro- ducing this difeafe, becaufe I have known many inftances of the acid being produced and occafioning various difor- ders, without, however, its ever producing rickets. Another of the remote caufes commonly affigned, is the child's being fed with unfermented farinaceous food; But over the whole world, children are fed with fuch farinacea, while the difeafe of rickets is a rare occurrence : And I have known many inftancest where cbjldrenj^ayg, beeojggi 258 PRACTICE with a greater than ufual proportion of fermented farina- cea, and alfo a greater proportion of animal food, without thefe preventing the difeafe. In my apprehenfion, the like obfervations might be made with refpect to moft ofthe cir- cumftances that have been mentioned as the remote caufes of rickets. 1725.] Having thus offered my opinion concerning the fuppofed antecedents of this difeafe, I proceed now to men- tion the phenomena occurring after it has actually come on.* The difeafe feldom appears before the ninth month, and feldom begins after the fecond year, of a child's age. 111 the interval between thefe periods, the appearance of the difeafe L> fometimes fooner, fometimes later; and common- ly at firft the difeafe comes on flowly. The firft appear- ances are, a flaccidity of the flefh, the body at the fame time becoming leaner, though food be taken in pretty large- ly. The head appears large with refpect to the body; with the fontanelle, and perhaps the futures, more open than ufual in children of the fame age. The head con- tinues to grow larger; in particular, the forehead becom- ing unufually prominent; and at the fame time the neck continues flender, or feems to be more fo, in proportion to the head. The dentition is flow, or much later than ufual; and thofe teeth which come out, readily become black, and frequently again fall out. The ribs lofe their convex- ity, and become flattened on the fides; while the fternum is pufhed outward, and forms a fort of ridge. At the fame time, or perhaps fooner, the epiphyfes at the feveral joints of the limbs become fwelled; while the limbs between the joints appear, or perhaps actually become, more flender. The bones feem to be every where flexible, becoming va- rioufly diftorted; and particularly the fpine ofthe back be- coming incurvated in different parts of its length. If the child, at the fame time the difeafe comes on, had acquired the power of walking, it becomes daily more feeble imits motions, and more averfe to the exertion of them, lofing at length the power of walking altogether. Whilft thefe fymp- toms go on increafing, the abdomen is always full, and preter- naturally tumid. The appetite is often good, but the ftools are generally frequent and loofe. Sometimes the faculties ofthe mind are impaired, and ftupidity or fatuity prevails; » '1«.. admirable defcription of the difcafe merits the peculiar attention of the young practitioner. Or r K T 3 I C. 25? but commonly a premature fenfibility appears, and they acquire the faculty of fpeech fooner than ufual. At th# firft coming on of the difeafe, there is generally rro fever at- tending it: but it feldom continues long, till a frequent pulfe, and other febrile fymptoms, come to be conftantly prefent. With thefe fymptoms the difeafe proceeds, and continues in fome inftances for fome years; but very often, in the courfe of that time, the difeafe ceafes to advance, and the health is entirely eftablifhed, except that the dis- torted limbs, produced during the difeafe, continue for the reft of life. In other cafes, however, the difeafe proceeds increafing, till it has affected almoft every function of the animal ceconomy, and at length terminates in death. The variety of fymptoms which in fuch cafes appear, it does not feem neceffary to enumerate, as they are not effential to the conftitution of the difeafe, but are merely confe- quences of the more violent conditions of it. In the bo- dies of thofe whohave died, various morbid affections have been difcovered in the internal parts. Moft of the vifcera of the abdomen have been found to be preternaturally en- larged. The lungs have alfo been found in a morbid ftate, feemingly from fome inflammation that had come on to- wards the end of the difeafe. The brain has beqn com monly found in a flaccid ftate, with effufions of a ferous fluid into its cavities. Very univerfally the bones have been found very foft, and fo much foftenedas tobe readily cut by a knife. The fluids have been always found in a diffolved ftate, and the mufcular parts very foft and ten- der; and the whole of the dead body without any degree of that rigidity which is fo common in almoft all odiers. 1726.] From thefe circumftances ofthe difeafe, it feems to confift in a deficiency of that matter which fliould form the folid parts of the body. This efpecially appears in the faulty ftate of offification, feemingly depending upon the deficiency of that matter which fliould be depofited in the membranes which are deftined tobecome bony, and fhould give them their due firmnefs and bony hardnefs.. Itappears that this matter is not fupplied in due quantity; but that in place of it, a matter fitted to increafe their bulk, parti- cularly in the epiphyfes, is applied too largely. What this deficiency of matter depends upon, is difficult to be afcer- tained. It may be a fault in the organs- of digeftion and af- 260 PRACTICE es. ___ finidation, which prevents the fluids in general from being properly prepared: or. it may be a fault in the organs of nutrition, which prevents the fecretion of a proper matter to be applied. With refpect to the latter, in what it may confift, I am entirely ignorant, and cannot even difcern that fuch a condition exifts: but the former caufe, both in its nature and exiftence, is more readily perceived; and it is probable that it has a confiderable influence in the mat- ter; as in rachitic perfons a thinner ftate of the blood, both during life and after death, fo commonly appears. It is this ftate of the fluids, or a deficiency of bony matter in them, that I confider as the proximate caufe ofthe difeafe; and which again may in fome meafure depend upon a ge* neral laxity and debility of the moving fibres of the organs. that perform the functions of digeftion and affimilation. 1727.] There is, however, fomething ftill wanting to ex- plain, why thefe circumftances difcover themfelves at a par- ticular time of life, and hardly ever either before or after a certain period ; and as to this I would offer the following conjectures. Nature having intended that human life fhould proceed in a certain manner, and that certain functions mould be exercifed at a certain period of life only ; fo it has generally provided, that at tharperiod, and not fooner, the body fliould be fitted for the exercife of the functions, fuited to it. To apply this to our prefent fubject, Nature feems to have intended that children fhould walk only at twel ve months old; and accordingly has provided that againft that age, and no fooner, a matter fhould be prepared fit to give that firmnefs to the bones which is neceffary to prevent their bending too eafily under the weight of the body. Nature, however, is not always fteady and exact in executing her own purpofes; and if therefore the preparation of bony matter fhall not have been made againft the time there is a particular occafion for it, the difeafe of rickets, that is, of foft and flexible bones, muft come on ; and will difcover itfelf about the particular period we have mentioned. Fur- ther, it will be equally probable, that if at the period men- tioned, the bones fhall have acquired their due firmnefs, and that nature goes on in preparing and fupplying the proper bony matter, it may be prefumed, that againft the time a child is two years old, fuch a quantity of bony matter will be applied, as to prevent the bones from becoming again OF PHYSIC. 261 foft and flexible during the reft of life; unlefs it happen, as indeed it fometimes does, that certain caufes occur to wafh out again the bony matter from the membranes in which it had been depofited. The account I have now given of the period at which the rickets occur, feems to confirm the opinion of its proximate caufe being a deficien- cy of bony matter in the fluids ofthe body. 1728.] Ii has been frequently fuppofed, that a fiphylitic taint has a fhare in producing rickets; but fuch a fuppofi- tion is altogether improbable. If our opinion ofthe rick- ets having exifted in Europe before the fiphylis was brought into it, be well founded, it wilhhen be certain that the difeafe may be occafioned without any fiphylitic acrimony having a fhare in its production. But further, when a fiphylitic acrimony is tranfmitted from the parent to the offspring, the fymptoms do not appear at a particular time of life on- ly, and commonly more early than the period of rickets; the fymptoms alfo are very different from thofe of rickets, and unaccompanied with any appearance ofthe latter; and, laftly, the fymptoms of fiphylis are cured by means which, in the cafe of rickets, have either no effect, or a bad one. It may indeed poffibly happen, that fiphylis and rickets may appear in the fame perfon; but it is to be con- fidered as an accidental complication : and the very few in- ftances of it that have occurred, are by no means fufficient tcT eftablifh any neceffary connection between the two difeafes. 1 729.] With refpect to the deficiency of bony matter? which I confider as the proximate caufe of rickets, fomei further conjectures might be offered concerning its remote caufes; but none of them appear to me very fatisfying; arid whatever they might be, it appears to me they muft again be refolved into the fuppofition of a general laxity and debility of the fyftem. 1730.] It is upon this fuppofition almoft alone that the cure of rickets has entirely proceeded. The remedies have been fuch efpecially as were fuited to improve the tone of the fyftem in general, or of the ftomach in "particular: and we know that the latter arc not only fuited to improve the rone of the ftomach itfelf, but by that means to improve alfo the tone of the whole fyftem. 1731.] Of tonic remedies, one ofthe moft promifing V u. 11. K. s 362 PRACTICE feems to have been cold bathing; and I have found it the moft powerful in preventing the difeafe. For a long time paft, it has been the practice in this country, with people of all ranks, to wafh their children from the time of their birth with cold water; and from the time that children are a month old, it has been the practice with people of better rank to have them dipped entirely in cold water every morn- ing: And wherever this practice has been purfued, I have not met with any inftance of rickets. Arnongft our com- mon people, although they wafh their children with cold water only, yet they do not fo commonly prafctife immer- fion: And when arnongft thefe I meet with inftances of rickets, I prefcribe cold bathing; which accordingly has often checked the progrefs of the difeafe, and fometimes feems to have cured it entirely. 1732.] The remedy of Ens Veneris, recommended by Mr. Boyle, and fincehis time very univerfally employed, is to be confidered as entirely a tonic remedy. That or fome other preparation of iron I have almoft conftantly employed, though not indeed always with fuccefs. I have been perfuaded, that the ens veneris of Mr. Boyle, not- withftanding his giving it this appellation, was truly a pre- paration of iron, and no other than what we now name the Flores Martiales:* But it appears, that both Benevoli and iL 1739.] JL HE character of this difeafe I have attempted in my Nofology: But it will be more properly taken from the whole of its hiftory, now to be delivered, i- . ^ . S I C. 265 1740.] It is commonly, and very generally, a hereditary difeafe; and although it fometimes may, yet it rarely ap- pears, but in children whofe parents had at fome period of their lives been affected with it. Whether it may not fad to appear in the children of fciQphulous parents, and dif- cover itfelf afterwards in their offspring in the fucceeding generation, I cannot certainly determine ; but believe that this has frequently happened. It appears to me to be deriv- ed more commonly from fathers than from mothers; but whether this happens from there being more ferophulous men than ferophulous women married, I am not certain. With refpect to the influence of parents in producing this difeafe, it deferves to be remarked, that in a family of many children, when one of the parents has been affected with fcrophula, and the other not; as it is ufual for fome of the children to be in conftitution pretty exactly like the one parent, a-id others of them like the other; it commonly happens, that thofe children who moft refemble the fero- phulous parent become affected with fcrophula, while thofe refembling the other parent entirely efcape. 1741.] The fcrophula generally appears at a particular period of life. It feldom appears in the. firft, or even in the fecond year of a child's life; and moft commonly it oc- curs from the fecond, or, as foniealledge, and perhaps more properly, from the third, to the feventh year. Frequently, however, it difeovers itfelf ata later period; and there are inftances of its firft appearance, at every period till the age of puberty; after which, however, the firft appearance of it is very rare. 1742.] When it does not occur very early, we can ge- nerally diftinguifh the habit of body peculiarly difpofed to it. It moft commonly aficcts children of foft am\Jlaccid habits, of fair hair and blue eyes; or at leaft affects thofe much more frequently than thofe of an oppofite complexion. It affects efpecially children of fmooth fkins and rofy cheeks and fuch children have frequently a tumid upper lip, with a chop in the middle of it; and this tumour is often con- fiderable, and extended to the columna nafi and lower part of thenoftrils. The difeafe is foretimes joined with, or follows rickets; and although it frequently appears in chil- dren who have not had rickets in any great degree, yet it often attacks thofe who, by a protuberant forehead, by tu- 266 PRACTICE mid joints, and a tumid abdomen, fhow that they had fome rachitic difpofition. In parents who without having had the difeafe themfelves, feem to produce ferophulous chil- dren, we can commonly perceive much of the fame habit and conftitution that has been juft now defcribed. Some authors have fuppofed that the fmall pox has a tendency to produce this difeafe; and Mr. De Haen afferts its followirigthe inoculated, more frequently than the natural, fmall pox. This laft pofition, however, we can confident- ly affirm to be a miftake; although it muft be allowed, that in fact the fcrophula does often come on immediately af- ter the fmall pox. It is, however, difficult to find any connection between the two difeafes. According to my obfervation, the accident only happens in children who have pretty manifeftly the feropriulous difpofition; and I have had feveral inftances of the natural fmall pox coming upon children affetted at the fame time with fcrophula, not only without this difeafe being any ways aggravated by the fmall pox, but even of its being for fome time after much relieved. 1743.] The fcrophula generally fhows itfelf firft ata particular feafon of the year; and at fome time between the winter and fummer folftice; but commonly long before the latter period. It is to be obferved further, that the courfe of the difeafe is ufually connected with the courfe of the feafons. Whilft the tumours and ulcerations pecu- liar to this difeafe, appear firft in the fpring, the ulcers are frequently healed up in the courfe of the fucceeding fum- mer, and do not break Out again till the enfuing fpring, to follow again with the feafon the fame courfe as before. 1744.] Frequently the firft appearance of the difeafe is the tumid and chopped lip above-mentioned. Upon other occaflnns the firft appearance is that of finall fpherical or oval tumours, moveable under the fkin. They are foft, but with fome elafticity. They are without pain; and without any change in the colour of the fkin. In this ftate they often continue for a long time; even for a year or two, and fometimes longer. Moft commonly they firft appear upon the fides of the neck below the ears; but fometimes alfo under the chin. In either cafe, they are fuppofed to affect in thefe places the conglobate or lym- phatic glands only; and not at all the falivary glands, till- OF PHYSIC. ser the difeafe is very greatly advanced. The difeafe fre- quently affects, and even at firft appears in, other parts of the body. In particular, it affefts the joint* of the elbows and ankles, or thofe of the fingers and toes. The appear- ances about the joints are not commonly, as elfewhere, fmall moveable fwellings; but a tumour almoft uniformly furrounding the joint, and interrupting its motion. 1745-J Thefe tumours, as I have faid, remain for fome time little changed; and, from the time they firft appeared in the fpring, they often continue in this way till the return of the fame feafon in the next, or perhaps the fecond year after. About that time, however, or perhaps in the courfe ofthe feafon in which they firft appear, the tumour be- comes larger and more fixed; the fkin upon it acquires a purple, feldom a clear rednefs: but growing redder by degrees, the tumour becomes fofter, and allows the fluc- tuation of a liquid within to be perceived. All this pro- cefs, however, takes place with very littiepain attending it. At length fome part of the fkin becorfres paler; and by one or more fmall apertures a liquid is poured out. j 746.] The matter poured out has at firft the appear- ance of pus, but it is ufually of a thinner kind than that from phlegmonic abfeeffes; and the matter as it continues to be difcharged, becomes daily lefs purulent, and appears more and more a vifcid ferum, intermixed with fmall pieces of a white fubftance refembling the curd of milk. By de- grees the tumour almoft entirely fubfides while the ulcer opens more, and fpreads broader: unequally, however, in different directions, and therefore is without any regular circumfcription.—The edges of the ulcer arc comrr.or.lv flat and fmooth, both on their outfide and their inner edge, which feldom puts on a callous appearance. The ulcer?, however, do not generally fpread much, or become deep- er; but at the fame time their edges do not advance, or put on any appearance of forming a cicatrix. 1747.] In this condition the ulcers often continue for a long Dme; while new tumours, with ulcers fucceeding them in the manner above defcribed, make their appearance in different parts of the body. Of the firft ulcers, how- ever, fome heal up, while other tumours and ulcers appear in their vicinity, or in other parts of the body: And in this manner the difeafe proceeds, fome of the ulcers healing up, 268 PRACTICE at leaft to a certain degree, in the courfe of fummer, and breaking out in the fucceeding fpring: Or it continues, by new tumours and ulcers fucceeding them, in the fpring fea- fon, making their appearance fuccetfively for fevcral years. 1748.] In this way the difeafe goes on for fevcral years; but very commonly in four or five years it is fpontaneouf- ly cured, the former ulcers being healed up, and no new tumours appearing: And thus at length the difeafe ceafes entirely, leaving only fome indelible efchars, pale and fmooth, but in fome parts fhriveiled; or, where it had oc- cupied the joints, leaving the motion of thefe impaired, or entirely deftroyed. 1749.] Such is the moft favourable courfe of this dif- eafe; and with us, it is more frequently fuch, than other- wife: But it is often a more violent, and fometimes a fatal malady. In thefe cafes, more parts of the body are at the fame time affected; the ulcers alfo feeming to be imbued; with a peculiarly fharp acrimony, and therefore becoming more deep, eroding, fpreading, as well as feldomer healing up. In fuch cafes, theVyes are often particularly affeBed. The edges of the eyelids are affected with tumour and fuper- ficial ulcerations; and thefe commonly excite obftinate in- flammation in the adnata, which frequently produces an opacity PRACTICE 1754.] For the cure of fcrophula, we have not yet learn- ed any practice that is certainly or even generally fuccefsful. The remedy which feems to be the moft fuccefsful, and which our practitioners efpecially truft to and employ, is the ufe of mineral waters; and indeed the waffling out, by means of thefe, the lymphatic fyftem, would feem to be a meafure promifing fuccefs: but in very many inftances of the ufe of thefe waters, I have not been well fatisfied that they hadihortened.the duration of the difeafe more than had often happened when no fuch remedy had been employed. 1755. J With regard to the choice of the mineral waters moft fit for the purpofe, I cannot with any confidence give an opinion. Almoft all kinds of mineral waters, whether chalybeate, fulphureous or faline, have been employed for the cure of fcrophula, and feemingly with equal fuccefs and reputation; A circumftance which leads me to think, that, if they are ever fuccefsful, it is the elementary water that is the chief part of the remedy. Of late, fea water has been efpecially recommended and employed; but after numerous trials, I cannot yet difcover its fuperior efficacy. 1756. J The other remedies propofed by practical wri- ters are very numerous; but, upon that very account, I apprehend they are little to be trufted: and as I cannot perceive any juft reafon for expecting fuccefs from them, I have very feldorn employed them. Of late, the Peruvian bark has been much recommend- ed : And as in ferophulous perfons there are generally fome marks of laxity and flaccidity, this tonic may poffibly be of fervice; but in a great variety of trials, I have never feen it produce any immediate cure of the difeafe. In feveral inftances, the leaves of coltsfoot have appear- ed to me to be fuccefsful. I have ufed it frequently in ftrong decoction, and even then with advantage; but have found more benefit from the expreffed juice, when the plant could be had in fomewhat of a fucculent ftate, foon after its firft appearance in the fpring. 1757.] I have alfo frequently employed the hemlock, and have fometimes found it ufeful in difcuffing obftinate fwellings: But in this, it has alfo often difappointed me; and I have not at any time obferved that it difpofed fero- phulous ulcers to heal. OF PHYSIC. 271 I cannot conclude the fubject of internal medicines with- out remarking, that I have never found, either mercury or antimony, in any fhape, of ufe in this difeafe; and when any degree of a feverifh ftate had come on, the ufe of mer- cury proved manifeftly hurtful. 1758.] In the progrefs of fcrophula, feveral external medicines are requifite. Several applications have been V ufed for difcuffing the tumours upon their firft coming on; but hitherto my own pra6tice, in thefe reflects, has been attended with very little fuccefs. The folution of faccha- rum faturni has teemed to be ufeful; but it has more fre- quently failed: And I have had no better fuccefs with the fpiritus Mindereri. Fomentations of every kind frequent- ly have been found to do harm; and poultices feem only to hurry on a fuppuration. I am doubtful if thi., laft be ever pra6tifed with advantage; for ferophulous tumours fometimes fpontaneoufly difappear, but never after any degree of inflammation has come upon them; and there- fore poultices, which commonly induce inflammation, prevent that difcuffion of tumours, which might otherwife have happened. Even when ferophulous tumours have advanced towards fuppuration, I am unwilling to haften the fpontaneous open- ing, or to make it by the lancet; becaufe I apprehend the ferophulous matter is liable to be rendered more acrid by communication with the air, and to become more eroding and fprcading than when in its inclofed ftate. 1759-J 1 ne management of ferophulous ulcers has, fo far as I know, been as little fuccefsful as that of the tu- mours. Efcharotic preparations, ofeither mercury or cop- per, have been fometimes ufeful in bringing on a proper fuppuration, and thereby difpofing the ulcer to heal; but they have feldom fucceeded, and more commonly they have caufed the ulcer to fpread more. The efcharotic from which I have received moft benefit is burnt alum, and a portion of that mixed with a mild ointment, has been as ufeful an application as any I have tried.- The applica- tion, however, that I have found moft ferviceable and very univerfally admiffible, is that of linen cloths wetted with cold water, and frequently changed when they are becom- ing dry, it being inconvenient to let them be glued to the fore. They are therefore to be changed frequently during 272 PRACTICE the day; and a cloth fpread with a mild ointment or plafter may be applied for the night. In this practice I have fometimes employed fea water; but generally it proved too irritating; and neither that nor any mineral water has ap- peared to be of more fervice than common water. 1760.] To conclude what I have to offer upon the cure of fcrophula, I muft obferve, that cold bathing feems to have been of more benefit than any other remedy that I have had occafion to fee employed. CHAP. II. £Df ^ipbiUaf, or tfce Oenereal Disease, 1761.] XjlFTER practitioners have had fo much expe- rience in treating this difeafe, and after fo many books have been publifhed upon the fubject, it does not feem neceffa- ry, or even proper, for me to attempt any full treatife con- cerning it; and I fhall therefore confine myfelf to fuch general remarks, as may ferve to illuftrate fome parts of the pathology or of the practice. 1762. J It is fufficiently probable, that anciently, in cer- tain parts of Afia, where the leprofy prevailed, and in Eu- rope after that difeafe had been introduced into it, a difeafe ofthe genitals, refembling that which now commonly arifes' from fiphylis, had frequently appeared: but it is equally probable, that a new difeafe, and what we at prefent term Siphylis, was firft brought into Europe about the end of the fifteenth century ; and that the diftemper now fo fre- quently occurring, has been very entirely derived from that which was imported from America at the period mentioned.* 3 763-] This difeafe, at leaft in its principal circumftan- ces, never arifes in any perfon but from fome communica- tion with a perfon already affe£ted with it. It is moft com- monly contracted in confequence of coition with an infect- ed perfon ; but in what manner the infection is communi- cated, is not clearly explained. I am perfuaded, that in coi- tion, it is communicated without there being any open ul- * Various opinions have been held by different phyficians about the origin of this difeafe; fome fuppofing it to have exifted in the old world, while others tliinlc it was imported from the new world difcovered by Columbus. The difpute produced many controvcrfial traits, from the perufal of which, the young practitioner can gain little advantageous knowledge. All that we certainly kilowabout the origin of the difeafe is, that it was firft obferved among the French, when they were at Naples in the year 14.03, and that it was brought into France by the French who returnee! thither with Charles Columbus landed at Paloson the 15th March in the fame year, on his return from his lirft voyage* .The difeafe therefore, if imported by Columbus's crew muft have fpread rapidly through Europe. ' OF PHYSIC. • 273 cer either in the perfon communicating or in the perfon re- ceiving the infection ; but in all other cafes, I believe it is never communicated in any other way than by a contact of ulcer, either in the perfon communicating, or in the perfon receiving the infection. 1764.J As it thus arifes from the contact of particular parts, fo it always appears firft in the neighborhood ofthe parts to which the infecting matter had been immediately applied; and therefore, as moft commonly contracted by coition, it generally appears firft in the genitals. 1765.] After its firft appearance in particular parts', more efpecially when thefe are the genitals of either fex, its ef- fects for fome time feem to be confined to thefe parts; and indeed, in many cafes, neverextcnds further. In other cafes however, the infecting matter paffes from the parts firft af- fected, and from the genital, therefore, into the blood-vef- fels; and being there diffufed, produces diforders in many other parts of the body. From this view of the circumftances, phyficians have very properly diftinguifhed the different ftates ofthe dif- eaje, according as they are local or are more univerfal. To the former they have adapted appellations fuited to the man- ner in which the difeafe appears: and to the other the gene- ral affection, they have almoft totally confined the appella- tions of Siphylis, Lues Venerea, or Pox. In the remarks I am now to offer, I fhall begin with confidering the local affection. 1 j66.] This local affeftion appears chiefly in the form of gonorrhoea or chancre. The phenomena of gonorrhoea,either upon its firft com- ing on or in its after progrefs, or the fymptoms of ardor urina?, chordee, or others attending it, it is not neceffary for me to defcribe. I fliall only here obferve, that the chief circumftance to be taken notice of, is the inflamed ftate of the urethra, which I take to be infeparable from the difeafe. 1767.] In thefe well known circumftances, the gonor- rhoea continues for a time longer or fhorter, according to the conftitution of the patient; it ufually remaining longeft in the moft vigorous and robuft, or according to the pa- tient's regimen, and the care taken to relieve or cure the difeafe. In many cafes, if by a proper regimen the irrita- tion of the inflamed ftate is carefully avoided, the gonor- £74 PRACTICE rhoEa fpomaneoufly ceafe?, the fymptoms of inflammation gradually abating, the matter difcharged becoming of a thicker and more vifcid confiftence, as well as of a whiter colou-; till at length, the flow of it ceafes altogether; and whether it be thus cured fpontaneoufly, or by art, the dif- eale often exifts without communicating any infection to the other parts ofthe body. 1768.] In other cafes, however, the difeafe having been neglected, or by an improper regimen aggravated, it con- tinues with all its fymptoms for a long time; and produces various other diibiders, in the genital parts, which, as com- monly taken notice of by authors, need not be defcribed here. I flnJl only obferve, that the inflammation ofthe urethra, which at firft feems to be feated chiefly, or only, in its anterior parts, is in fuch neglected and aggravated cafes fpread upwards along the urethra, even to the neck ofthe bladder. In thefe circumftances, a more confider- able inflammation is occafioned in certain parts ofthe ure- thra; and confequently, fuppuration and ulcer are produc- ed by which the venereal poifon is fometimes communi- cated to the fyftem, and gives rife to a general fiphylis. 1769.3 It was fome time ago a pretty general fuppofi- tion, that the gonorrhoea depended always upon ulcers of the urethra, producing a difcharge of purulent matter; and fetch ulcers do indeed fometimes occur in the manner that has been juft now mentioned. We are now afiured, how- ever, from many directions of perfons who had died when labouring under a gonorrhoea, that the difeafe may exift, and from many confiderations it is probable that it com- monly does exift, without any ulceration of the urethral fo that the difcharge which appears, is entirely that of a vi- tiated mucus from the mucous follicles ofthe urethra. 1770.3 Although moft of the fymptoms of gonorrhoea fhould be removed, yet it often happens that a mucous fluid continues to be difchanied from the urethra for a longtime aiter, and fometimes for a great part of a perfon's life. This difcharge is what is commonly called a Gleet. With refpect to this, it is proper to obferve, that in fome cafes, when it is certain the matter difcharged contains no venereal poifon, the matter may, and often docs put on that puriform appearance, and that yellow and greenifh colour, which appears in the difcharge at the beginning and durin* O F P H Y S I C. z,l5 the courfe of a virulent gonorrhoea. Thefe appearances in the matter of a gleet which before had been of a lefs co- loured kind, have frequently given occafion to fuppofe that a frefh infefction had been received: But I am certain that fuch appearances may be brought on by, perhaps, various other caufes; and particularly, by intemperance in venery and drinking concurring together. I believe, indeed, that this feldom happens to any but thofe who had before fre- quently laboured under a virulent gonorrhoea, and have more or lefs of gleet remaining with them: But I muft al- fo obferve, that in perfons who at no period of their life had ever laboured under a virulent gonorrhoea, or any other fymptom of fiphylitic affection, I have met with in- ftances of difcharges from the urethra refembling; thofe of a virulent gonorrncea. The purpofe of thefe obfervations is, to fuggeft to prac- tioners what I have not found them always aware of, that in perfons laboring under a gleet, fuch a return of the ap- pearances of a virulent gonorrhoea may happen without any new infection having been received, and confequently not requiring the treatment which a new infection might perhaps demand. When, in the cure of gonorrhoea, it was the praBice to employ purgatives very frequently,and fome- times thofe of the draftic kind, I have known the gleet, or fpurious gonorrhoea, by fuch a practice much increaicdand long continued, and the patient's conftitution veiy much hurt. Nay in order more certainly further to prevent mif- takes, it is to be obferved, that the fpurious gonorrhoea is fometimes attended with heat of urine, and fome degree of inflammation; but thefe fymptoms are feldom confiderable, and merely by the affiftance of a cool regimen, commonly difappear in a few days. 1771.3 With refpect to the cure of a virulent gonorrhoea, I have only to remark, that if it be true, as I have menti- oned above, that the difeafe will often, under a proper re- gimen, be fpontaneoufly cured ; and that the whole of the virulent matter may be thus entirely difcharged without the affiftance of art; it would feem that there is nothing requi- red of practitioners, but to moderate and remove that in- flammation which continues the dileale, and occaiions ;]! the troublefome fymptoms that ever attend it. The fole bufinefs therefore of our art in the cure of gonorrhoea, is 276 PRACT/CE to take off the inflammation accompanying it: And this I think may commonly be done, by avoiding exercife, by ufing a low and cool diet, by abftaining entirely from ler- mcnted and fpirituous liquors, and by taking plentifully of mild diluent drinks.* 1772.J The heat of urine, which is fo troublefome. in this difeafe, as it arifes from the increafed fenfibility of the urethra in its inflamed ftate; fo, on the other hand, the ir- ritation of the urine has the effect of increafing the inflam- mation, and is therefore to be removed as foon as poffible. This can be done moft effeaually by taking in a large quan- tity of mild watery liquors. Demulcents may be employ- ed; but unlefs they be accompanied with a large quantity of water, they will have little effect.t Nitre had been com- monly employed as a fuppofed refrigerant: Bur., from much obfervation, I am convinced, that in a fmall quanti- ty it is ufelefs, and in a large quantity certainly hurtful ;J and, for this reafon, that every faline matter paffing with the urine generally gives fome irritation to the urethra. To prevent the irritation of the urethra arifing from its increaf- ed fenfibility, the injection of mucilage or of mild oil into it has been practifed; but I have feldom found this of much fervice. 1773J In gonorrhoea, as coftivenefs may be hurtful, both by an irritation of the fyftem in general, and of the urethra in particular, as this is occafioned always by the a- voidinjj of hardened faeces; fo coftivenefs is to be careful- ly avoided or removed ; and the frequent ufe of large gly- *This (imple method of curings gonorrhoea is, in many cafes fufficient, but it can only bedepend- rd on when the difeafe is (light and the patient of a heahhy conftitution.

If glyfters, however, do not entirely obvi- ate coftivenefs, it will be neceffary to give laxatives by the mouth: which, however, fliould be of the mildeft kind, and fhould do no more than keep the belly regular and a little loofe, without much purging.* The practice of frequent purging, which was formerly fo much in ufe, and is not yet entirely laid afide, has al- ways appeared to me to be generally fuperfluous, and of- ten very hurtful. Even what are fuppofed to be cooling purgatives, fuch as Glauber's fait, foluble tartar, and cry- ftals of tarter, in fo far as any part of them pafs by urine, they, in the fame manner as we have faid of nitre, may be hurtful; and fo far as they produce very liquid ftools, the matter of which is generally acrid, they irritate the rectum, and confequently the urethra. This laft effect, however, the acrid, and in any degree draftic, purgatives, more cer- tainly produce. J774'] 1° cafes of a gonorrhoea attended with violent inflammation, blood-letting may be of fervice; and in the cafe of perfons of a robuft and vigorous habit, in whom the difeafe is commonly the moft violent, blood-letting may be very properly employed. As general bleedings, how- ever, when there is no phlogiftic diathefis in the fyftem, have little effect in removing topical inflammation; fo in gonorrhoea, when the inflammation is confiderable, topical bleeding applied to the urethra by leeches, is generally more effectual in relieving the inflammation.t 1775. J When there is any phymofis attending a gonor- nicea, emollient fomentations applied to the whole penis are often of fervice. , In fuch cafes it is neceffary, and in all others ufeful, to keep the penis laid up to the belly, when the patient either walks about or is fitting.^ # A tea-fpoonful of the following electuary taken occafionally will keep the belly fufficiently open. ft.

They may be applied en the under fide of the penis, and three or four thus applied have frequently produced amazing effects. The operation, however, is extremely painful, and is ieldom fubmittcd to a fecond time by a patient who has once experienced it. % In all cafes of inflammation of the urethra thefe emollient applications give great relief. The common white bread poultice may be ufed during the night time or while the patient Is in bed; and warm flannels impregnated with lmtXcecl-tea while he is fitting up. Vol. H. M m 278 PRACTICE 1776.] Upon occafion of frequent priapifm and chor- dee, it has been found ufeful to apply to the whole ofthe penis a poultice of crumb of bread moiftened with a ftrong folution of fugar of lead. I have, however, been often difappointed in this praBice, perhaps by the poultice keep- ing the penis too warm, and thereby exciting the very fymp- toms I wifhcd to prevent. Whether lotions of the exter- nal urethra with a folution of the fugar of lead, might be ufeful in this cafe, I have not properly tried* 1777.] With refpea to the ufe of injcBions, fo frequent- ly employed in gonorrhoea, I am perfuaded, that the early ufe of aftringent injections is pernicious; not by occafion- ing a fiphylis, as has been commonly imagined; but by increafing and giving occafion to all the confequences of the inflammation, particularly to the very troublefome fymptoms of fwelled tefticles. When, however, the dif- eafe has continued for fome time, and the inflammatory fymptoms have very much abated, I am of opinion, that by injections of moderate aftringency, or at leaft of this gradually increafed, an end may be fooner put to the dif- eafe than would otherwife have happened; and that a gleet, fo readily occurring, may be generally pre vented.t 1778.] Befides the ufe of aftringent injections, it has been common enough to employ thofe of a mercurial kind. With refpeft: to thefe, although I am convinced that the infection producing gonorrhoea, and that producing chan- cres and fiphylis, are one and the fame; yet 1 apprehend, that in gonorrhoea mercury cannot be of ufe by correcting the virulence ofthe infection; and therefore that it is not * The fugar of lead folution may perhaps be objected againft on account of its flopping the dip- ' charge, and inducing i fwelled fefticle, which has fometimes followed its application. Wrapping the penis up in linen rags wet with cold water, frequently anfwers the purpofe of preventing the vi- olence of the fymptoms, as well as any more complicated application. The cold wet rags ought to be renewed whenever they grow warm. t The practice of uling aftringent injections is extremelv common ; but (as the author jullly ob- ferves} their ufe is frequently attended with difagreeable confcquences. In general they do harm when ufed during the continuance ofthe inflammatory fymptoms, or even too foon after thefe fymp- toms have disappeared. If, however, (after the inflammatory fvmptoms are overcome, and mercury has been ufed for fix -v^eeks or two months in the manner defenbed in the note on article 1771J the running ftill continues, \ve^nay then have recourfe to thefe altringent injections.

' »ui.s.uu» OF PHYSIC. 379 univerfally neceffary in this difeafe, I am perfuaded, how- ever, that mercury applied to the internal furface of the urethra, may be of ufe in promoting the more full and free difcharge of virulent matter from the mucous glands of if. Upon this fuppofition, I have frequently employed mercurial injections; and, as I judge, with advantage; thofe injec- tions often bringing on fuch a ftate of the confiftence and colour of the matter difcharged, as we know ufually to pre- cede its fpontaneous ceafing. I avoid thefe injections, however, in recent cafes, or while much inflammation is ftill prefent; but when that inflammation has fomewhat abated, and the difcharge notwithflanding ftill continues in a virulent form, I employ mercurial injections freely. I employ thofe only that contain mercury entirely in a liquid form, and avoid thofe which may depofit an acrid powder in the urethra. That which I have found moft ufeful is a folution of the corrofive fublimate in water; fo much di- luted as not to occafion any violent fmarting, but not fo much diluted as to give no fmarting at all. It is fearce neceffary to add, that when there is reafon to fufpect there are ulcerations already formed in the urethra, mercurial injections are not only proper, but the only effectual re- medy that can be employed. 1779.] With regard to the cure of gonorrhoea, I have onlv one other remark to offer. As moft of the fymptoms arife from the irritation of a ftimulus applied, the effects of this irritation may be often Icffcncd by diminifhing the ir- ritability of the fyftem; and it is well known, that the moft certain means of accomplifhing this is by employing opium. For that reafon, I confider the practice both of applying opium directly to the urethra,* and of exhibiting it by the mouth, to be extremely ufeful in molt cafes of gonorrhoea. 1780.] After thus offering fome remarks with refpect to gonorrhoea in general, I might proceed to confider par- ticularly the various fymptoms which fo frequently attend it; but it does not feem neceffary for me to attempt this af- ter the late publications of Dr. Foart Simmons, and of Dr. Schwediaur, who have treated the fubject fo fully, and with fo much difcernment and fkill.t * Opium mav be very conveniently applied to the urethra by injeaion ; and for this purpofe a di- luent folution of opium in water is preferable to a fpirituous or vinous folution.. A grain of opium dilfolved in an ounce of water, and the folution (trained, may be injected twice or thrice a day; and thirty or forty drops of laudanum may be given every night at bed tirne. , + As a fwelled tclticlc frequently attends a fuppreffed gonorrhoea, it may be proner to give the young practitioner fome directions concerning the management of it,—Sometimes without any other 280 PRACTICE 1781.] The other form of the local affeaion of fiphylis, is that of chancre. The ordinary appearance of this I need not defcribe, it having been already fo often done. Of the few remarks I have to offer, the firft is, that I believe chancres never appear in any degree without immediately communicating to the blood more or lefs of the venereal poifon: For I have conftantly, whenever chancres had ap- peared, found, that unlefs mercury was immediately given internally, fome fymptoms of a general fiphylis did certain- ly come on afterwards; and though the internal ufe of mercury fliould prevent any fuch appearance, it is ftill to be prefumed that the poifon had been communicated, be- caufe mercury could act upon it in no other manner than as diffufed in the fluids. 1782.] It has been a queftion among practitioners, up- on the fubject of chancres, Whether they may be imme- diately healed up by applications made to the chancres, or if they fhould be left open for fome time without any fuch application? It has been fuppofed, that the fudden healing up of chancres might immediately foYce into the blood a poifon which might have been excluded by being difcharg- ed from the chancre. This, however, is a fuppofition that is very doubtful; and, upon the other hand, I am certain, that the longer a chancre is kept open, the more poifon it perhaps generates, and certainly fupplies it more copioufly to the blood. And although the above-mentioned fuppo- fition were true, it will be of little confequence, if the in- ternal ufe of the mercury, which I judge neceffary in eve- ry cafe of chancre, be immediately employed.
