ADVERTISEMENT. ® The ensuing Treatise, has before appeared in detached Essays in the Southern Patriot Gazette. The talent displayed in the Editorial department of that Paper, and the readiness with which its columns are opened to all such discussions as promise or pro- mote any useful end, have secured to it a very general circulation; it might therefore seem scarcely neces- sary again to bring forward opinions, which have al- ready received extended publicity. The author how- ever, was solxited by his friends to embody his ideas in a more permanent form, and yielded the more wil- lingly to their desire, as the present publication af- forded an opportunity of correcting many errors, and supplying some omissions, which unavoidably oc- curred in the haste with which its different parts were first sent to the press. CHAPTER I. On the Origin of the Disease. Of the various opinions and theories which have tit different times been offered to the public, on the subject of Yellow Fever, there are none, it is gene- rally admitted, which are at all satisfactory either as to the nature or origin of the disease, or the pro- per mode of treating it Its late ravages in most of our principal Cities, and the probability of its fre- quent and even spe rations a resoit to svste us of non-inter- course, and quarantine restrictions, that have a seri- ous efivct upon the co nmerce of the Country, an 1 vexatiously interrupt the communication hetween the different portions of the Union. I hope to place the suoje.t in an entire new light, and to illustrate it by some tacts, which as far as my knowledge extends, have never before been brought forward, or adverted to. But though it is not my intention to go over, or re- capitulate the usual arguments employed by the Non- Contagionists in this dispute, their .reasonings and statement* are too much to my purpose to oe whol- ly overlooked; I shall therefore adjoin various ex- tracts, in the form oi an appendix, which will be found to exhibit a view of the principal grounds re- lied on, by the writers on this side of the question. The doctrine is at once so rational, and is supported bv so many obvious facts, that, it had at one time made its way to almost universal reception; but some dis- trust of its correctness has latterly been entertained from its having been observed, that our Cities have often enjoyed an exemption from the pestilence, du- ring those seasons, when the causes which are ordi- narily supposed to be the most concerned i» its pro- duction, (such as the effluvia from docks, drains, sinks, £jc.) have existed in lull operation, while, vice vena, some of its severest visitations have occurred at periods, when the circumstances of the climate, and the strict execution of our police laws, have seemed to promise us aiieedom from its attacks: and that finally, in seasons of totally opposite charac- ter, either very wet or very dry, it has still made its appearance. The medical world has been much puz- zled by tfiese phenomena ; and while some few adop- ted the notion of contagion, a majority of those who have specidated on the point, though they admit the disease to he of indigenous for nation, seem to have come to the conclusion, that its real cause is altoge- \ ther inscrutable, oris involved in some occult princi- « j pie or unknown condition of the general body of the le j atmosphere. All the above difficulties are, however, 1 conceive, to be solved, or in a measure reconcil- v ed. by advertence to a single fact, which has hither to been unaccountably overlooked; it is this; that ^ every period in which the Yellow Fever has ap- t ired in Charleston, the Summer, or season at large, ^ at pea has been unusually sickly, that is, the Country as well as the Town hai* been afflicted by Fevers of a fatal and violent tvpe I am enabled from my own experi- ence and observation in the course of the last twen- ty years, to bear testimony to this circumstance, the philosophical application of which seems at once ob- vious It is easy to perceive, that if to an atmos- phere, which has already, from various causes, be- come so deleterious, as to occasion general unhealthi- ness, be superadded, all those effluvia which from foul streets, sewers, £jc. are constantly contaminating the air of Cities, a malignant disease must necessa- rily be produced; and accordingly under such cir- cumstances, ,the Yellow Fever has invariably broken out, with ^cater or less violence, in proportion to the sickliness of the Country, or season generally.* * Another particular in the history of the Fever, remains to be ac- counted for, which is, that it is confined to maritime situations, or those within the influence of the Tide Waters of Rivers. It is probable that tuere is always a superabundance of moisture in these situations, whicii relaxes the human system, and throws it open to disease. The action of the sun or the waters during dry summers, in combination 6 * The causes arising within the City, acting alone, that is, during healthy Summers, are never sufficient to ' produce the Fever; Charleston being alwiys healthy, when the Country around it has continued free from any remarkable mortality. The Fevers of the Town and Country being thus always concomitant, surely indicatejbeyond the possibility of dispute, that they have a common origin, or are congenerous to the climate; though indeed widely distinguised from each other in symptoms and character. It is scarcely necess«ry to observe, that the t\ pe of the diseases in the two cases being wholly unlike, is simply ascribable to the difference of local circum- stances : the masmata which affect the air of the Country, are in the first place not so much confined and contracted as those of the City, and being most- ly of paludal and vegetable ongin, are of conse- 1 quence less pernicious than the putrescent and ani- mal effluvia, which arise from amidst the dense pop- ulation of the latter It will not be of course con- tended, that the Fevers of the country are either im- ported, or contagious ; yet that they do, as above sta- ted, make their appearance, and continue cotempo- raneously with the Yellow Fever, is, I reiterate, a con- currence, which has invariably taken place within my own experience.* Though I am unable to support this statement by any direct documentary evidence, there being no Pa- rish Registers regularly kept in any part of the State, with the agitation of the tides, would occasion a h*mi*mr of moisture at such seasons, nearly as great as that which exists in rainy periods. This would account for the Fevers appearing in seasons of entire op- posite character. * The sickness of the last year in the Country, which constantly kept pace with that in the City, and even penetrated to the Pine-land set- tlements, hitherto deemed healthy, is fresh in the recollection of every one. 7 yet sufficient testimony on this head may he gather- ed from the works of Chalmers and Huztt, who pre- face all the accounts they give of the Epidemics which desolated Charleston in the early part of its history, (which were undoubtedly Yellow Fever) by saying that the summer of those years, were unhealthy. That in using this language, they refered to the Coun- try as well as the Town, is I think fairly to be con- cluded, as those authors write the history of the co- lony at large; and the work of l)r. Chalmers is ex- pressly entitled an account oj the weather and diseas- es if Carolina. Another proof, which assists to throw light upon the connexion, subsisting between the states of the air in Town and Country, is, that a stanger, arriving direct from Europe, nay without risk spend the summer in Charleston, whenever it happens that the country around it is unvisited by sickness ; for the Town, as already observed, then also remains healthy, though the communication with the sea-ports of the West In- dies where the Yellow Fever permanently exists as an endemic, continues open and unrestricted.* It is, moreover, very observable, that a stranger does not obtain security by having been exposed to a season of this sort, but in order to be completely climated, must actually pass through a Yellow Fever summer: The safety acquired in the latter case, as well as the re- markable immunity enjoyed by natives cannot be ac- counted for but upon the hypothesis I have been ad- vocating, that of the domestic ingeneration of the dis- ease. It results from the mildness of our winter vi- cissitudes, which leave the system in possession of * Dr. Bancroft well remarks, that " while it is so notorious that the Yellow Fever cannot be propogated a single mile from Philadel- phia or New York, it is completely absurd to suppose that it can have been transported by a contagious quality one or two thousand miles across tbe Ocean* 8 that peculiar organical modification, which if under. goes by exposure to the epidemic in the fir t instance, when the plasticity of the animal economy enables it to adapt itself to the climate and to resist infection. The indiscriminate attack of the disorder upon both natives and strangers in the more Northern Cities, is to be explained upon an analagous principle. The severity of the winters in those places, while it de - troys all the seeds of the epidemic, creating a totally new climate, also produces an entire change in the constitution, obliterating all those summer habits of the system, which give saf ty to the inhabitants of Southern and tropical countries. Dr. Bancroft has broached an ingenious theory to account for the fe- vers being confined, as he erroneously believed, ex- clusively to strangers in warm climates. He sup- poses that the constitutions of those who come fr»>m higher lattitudes, kt are habituated to the generation of great portions of animal heat, and that the cold which forces this habit upon them, will naturally p ^- duce in them a considerable rigidity and strength of fibre, with an inflammatory diathesis, and that when they remove directly into an interttopical situ ttiei, they will commonly carry with them a great accumu- lation of excitability which co-operating with the es- tablished habit of generating much annn I heat there, may readily produce to them a most aggravated and violent form of fever, £$c." The Doctor however was not aware that Children in warm climate (it is at least the case in Charleston,) are from the age of one, up to twelve years, equally subject with stangers to the disease, this single circumstance totally destroys the effect of the above plausible explanation; for it is manifest that the constitutions of the inadult would become early adapted to the climate, and would not be in the habit of generating over proportions of heat, * any more than the older natives. * The liability of Children to take the fever until a certain age, I con- ceive to be owing to the alterations induced by growth upon their tender constitutions, which are constant- ly effacing those impressions of the climate, which become permanent in adults and strangers: they are hence placed in this respect on a worse footing than the latter, though they are certainly less apt than stran- gers, to take the disorder. We thus see that all the ano- malies and peculiarities which have been enumerated* become at once simplified, and are to be philosophi- cally accounted for, by admitting the doctrine o* the agency of climate and the operation of local causes, while they must forever remain inexplicable upon the hypothesis of importation or contagion. I shdl not deem it necessary to enter into a particular investi- gation of the merits of the latter opinion, but shall content myself with proceeding to notice some of those local peculiarities which seem to be in a very especial manner connected with the history of the Fever. The geographical limits to which it is so singular- ly confined, is a part of its history, requiring notice in discussing the important question of its erigin. It is generally known, to be restricted in its range, to the littoral borders, or maritime regions of the Ame- rican Continent, and the West Indies; never spread- ing in the Country, or beyond those places situated within the influence of the tide-waters of rivers: for though persons who have taken it in the latter places, have often carried it into the interior, the cases have always terminated with the individuals who have so conveyed it. I am aware that some of our Towns in * The Doctor speaks of an inflammatory diathesis, but neither dissec- tions nor external indications, evince that there is any thing inflamma- tory in the disease. The fever can only be regarded as a transient ef- fort of the vis-medicatrix of the constitution, exhibiting no marks*5 of his Letter to Doctor tlaygarth, introduces one to himself, from Doctor Hosack, da- ted, New-York, July 9th, 180«. in which there is an abundant display of zeal, I do not say for maintaining the cause of truth, but for assert- ing the supposed contagion and importation of Yellow Fever: heal- so communicates his intention to write and print a letter, charging Doctor Miller with " want of candour," in his official report to the governor; which charge he founds upon the following statement, viz. " As a member of the Board of Health, he (Dr. Miller) must have * known that the disease was confined for many weeks to a small por- tion of the eastern side of the city, and that, not a case occured in any other part of the town, that was not referable to that, as its source. Such was the statement of the Board of Health to our citizens, and, in consequence of which, they forbade intercourse with the infected portion of our city, and ordered an abandonment of that part of the town, &c." '• He adds, a 'few weeks after, the infection extended a few streets further. The Board of Health accurately defined its limits, and again declared, that still not a case occured but could be traced to this spot of the city, as its source Doctor Miller carefully enumerates the cases occuring, and the numerous pa ts of the city in which the sick reside, but as carefully suppresses the observation of the board, of which, too, he was a member, and must have known, that the per- sons so taken sick, had, prior to.their attack, been exposed t» the infection by frequenting the infected spot.'' How strangely Doctor Hosack here mistakes the obvious import or evidence of an important fact! One of the strongest proofs of the local origin of Yellow Fever, results from the circumstance of its beginning, and remaining, almost exclusively, in particular spots or situations. Of this, Doctqr Mil- ler was very sensible; and. if he omitted to state '• the observation of the board," respecting it, ha could only have done so because it ap- peared superfluous, after he had so distinctly mentioned the facts to which it related. And is it then possible, that Doctors Hosack and Chisholm can have been so inept as to believe that these facts could operate in supporting their opinion of the importation and contagious nature of this disease ? Do they conceive, that if it were contagious, it would have been so many weeks confined to one spot, and that when 14 lately raged there existed local causes, which uniting with a state of the air, that predisposed to sickness, gave rise to the disease. I shall proceed to ollvr'some suggestions towards preventing a recurrence of the disease among ourselves. On this subject, Philadelphia holds out to us an example, which we cannot too close- ly imitate. We have, indeed, already rmmy admirable ordinances, which only requite to be revived and en- forced, to place uson alevt-1 with that city, on the score of cleanliness, and excellence of police. It would i;e expedient, also, that the Legislature should ai I the City Council topiovide for the paving of our streets it afterwards « extended a few streets further." those onlv would have been attacked by it, who had vluted that identical sp->t? I his is ex- actly what would happen in regard to a disease not contagious, but arising from nvasmata; because, the soil in which they are produced bemg immoveable, and its exhalations incapable of causing disease, at any considerable distance from their source, persons to be acted upon by them must necessarily approach that source. But contagion having no such im moveable origin will not be thus confined ; persons infect- ed by it, and sickening in di^erent places, naturally \< feet others, who soon spread the disease widely, so that, the spot where it first appeared often becomes less dangerous than most others and its at- mosphere does not continue to produce disease, when the sick have been removed, and the houses shut up, as happens in cases of Yel- low Fever. With the same fatuity, Doctor Chisholm. in his letter to Doctor Havgarth, has published one from Doctor A. Fothergill, l.te of Bath, who, writing to the American Consul, at Bristol, of the Yel- low Fever at Philadelphia, in 1805, and mentioning that it had. in November, received a check, apparently from the cooler season set- ting in; adds, •'It remained fur some weeksa local disease in the southern suburbs," (adjacant. to the nu.r»hy low grounds, at the con- fluence of the Delaware and Schuylkill) •' but, at length, was commit* nicated to several of the principal streets in the city, as iar as Eighth Street, westward," (persons who had been exposed to miasmata in o- tlier places, happening to fall sick in these) " but it chiefly infested Water Street, Front Street." (running parallel with, and next to Wa- ter Street) *' and the margin of the Delaware" He adds, •* many of the professors, and medical practioners here, deny that the disease is contagious, and in this notion the body of merchants bear them out" Dr. Fothergill, however, adheres to the old notion of contagion and importation and no wonder that it should have adherent1-, in men who fancy they can see evidence of a contagious! quality, in facts which decidedly prove the contrary, to all who are aule to reason with im- partiality." Bancroft. 15 and hne«, as paved ways are more easily kept clean, than those, which are all the year deep in sand or mud, in which many animal and other putrescent remains, are often buried and concealed, while the exhalations from the mud, after wet weather, con- tribute greatly to impair the general state of the air. It would be further advisable, that the City Engineer should be employed to take the general level of the Town, and that the inequalities of the streets should be filled up, or levelled away, so as to afford a regular surface, from which by means of side drains, run- id ug to the waters edge, every offensive matter might ie completely carried off. The present sys- tem of subterraneous sewers, I consider as of more d. tiiment to the health of the City, than all the other so irces of infection put together. In addition to the ef- fluvia, arising from the mass of obstructed matter con- cealed wimiii them, the necessity of frequently open- ing diem and returning their foul contents to the sur- f ^ce, from which they are nexei removed, so that tiie soil of our sireets heeo nes a compost of every thing deleterious, is a disadvantage which calls tor their obliteration, or the effectual sealing up of their grates, as soon as proper side drains can be constructed. I am pHrsuaded, tiiat it would add much to the health ot the town, if the citizens would be induced to aban- don in the future construction of buildings, the pre- sentcustomof diggingsubterraneouscellars, which be- come receptacles tor foul air, and often from springs or rai s. form bodies of stagnant water. The ground on whi h our City stands, is of too low and springy a nature, to admit of tnese substructions. Cellars above ground would answer every purpose, and would not be attended by any of the above inconveniences. B.ing convinced the dreadful malady which has so often arrested the prosperity of our City, is of domes- tic ingcnei ation, I had hoped that to demonstrate this, 16 as far as I was able, might perhaps have the effect of exciting a more serious attention to the means of averting its visitations. I have pointed out some of these means, and have shewn that the happiest success has attended their adoption in other places. It was gen- erally understood that the Legislature would take up the subject, and perceive the policy and importance of making every effort to render the emporium of the State, the seat of Health, to which foreign rs may safely be invited to become competitors in our mar- ket, for the products of our industry. This reason- able expection however has been disappointed and the proposition to appropriate a sum of-money for the improvement of the City was rejected in that Body. It could not reasonably be required of the advo- cates of the measure, that they should furnish com- plete proof of the adequacy of preventive means to keep out the disease; the object proposed would ne- cessarily be somewhat of an experiment, but it is an experiment which ought to be made. If. however, satisfactory evidence on this head, be rigidly demand- ed, it may be said to be at hand, as we see in the in- stance of Philadelphia, that an exemption from trie infection has been obtained by a strict attention to preventive regulations. The last season was peculiarly calculated to test the effect of such regulations, as the Yellow Fever made its appearance in all its former haunts, and a- mong other places in Philadelphia, but there, as we have seen, created but little alarm and soon disap- peared. With this example before their eyes, of an apparent control exercised over the disease, quietly to look on, while hecatombs of victims among our- selves are almost annually swept off, is nothing less than criminal neglect in our public authorities. Our present system of public works, having for its uiti- mate object, the improvement of the Market o^ the Stite, the opposition to a measure, which was inten- ded to promote the same purpose, remains o be re- conciled with consistency. This proceeding, by which the work of improve Merit was arrested at HV very point, where it ought both to begin and to end, was indeed opposed by the best talents of the House, and stands recorded, as a measure of the wisdom and patriotism of a bare majority Soon af- ter the rejection of the appropriation for Charleston, a proposition w-.is introduced for the establishment of a Lunatic Asiium, which it must oe acknowledg- ed, followed in very natural order, and ougf tto have succeeded: the Institution it contemplated, would have afforded appropriate accommodations for those who on the former question, had sturdily withstood every evidence of truth, every plea of humanity, and manfully oppose I the plain interests of their constituents and the State No expense, it seems, is to be spared in the opening of our rivers, in construc- ting roads and canals, and producing a convergence of all these towards the Capital ; but the la'ter is to be left a prey to desolation, and the career of improve- ment is to stop short at its gates. The superinten- ding care of the Legislature extends no further than to the Lines of Charleston, there suddenly encoun- tering a magical barrier, which cannot be overpassed, or as if it were expected, th.it the corporation, which has only the municipal regulation of the city, should undertake and carry on those great objects of inter- nal policy, which were involved in the proposed ap- propriation. Bur fias corunat opus ought to be the motto of the Legislature on this subject; the im- provement and emhelhShment of the City ought to go on, hand in hand, with those other goodly works, wuich have been so happily begun, and be made to to crown the whole. Were this policy pursued, our c 19 Capital would, like the human body, acquire beau- ty as it improved in health, and become a point of increased attraction to trade and foreign enterprise. It would enjoy its due share in the vast prosperity of our country, and participate as largely as any other City of the Union, in its extended and increasing commerce, which Ranging every azure swell, And floating under every s+ar. places within our reach, the wealth and advantages of the remotest climes. W*V*/kW%VWW».VWWVWT «/WW*VWW»r all, to put an end to this ignorant mistake, first by ad lucing the de- cisive results of the dissections made by Dr. Physiek, whose name must ensure attention to every thin* which appears under its sanction. This great man whose science and success in his profession, have given it a new title to be called the Healing Art, and whose philanthropy and generous sympathies, impart to his medical attentions, the grace and consolations of friendship, has shed a broad and lasting li^htover this subject, which ought lona; since to have dissipated the errors that still prevail respecting it. To the ex- tra ts from his letter to Dr. Mitchell. I shall add the opinions of several other distinguished Physicians, illustrative of the same point. The following are the results of Dr. Physick's researches: •' the liver was generally found of a pale appearance. The mat- ter of Black Vomit, commonly found in the stomach, and sometimes in the intestines, was never discover. ed in the gall bladder, the liver, or any other viscus or cavity. The stomach has sometimes been load- ed with this black matter, while in the same subject, not only the liver was free from disease, but the bde in the gall-bladder was in its natural healthy state; and this in several cases where a contraction of the pylornus had completely obstructed the passage from the dusdenum into the stomach. The matter of black vomit is, besides, essentially different from bile; it differs in color, for however dark the bile may ap- pear in its most concentrated state, it always displays a yellowish or greenish yellow tinge, when spread on a white surface, or even diluted; but if the Black Vo- mit be treated in the s rme way, it retains its black or dark brown appearance. It has also been found that an addition of bile to the latter, altered its nature, and gave it consequently a different appearance i to nor could the Black Vomit be imitated by any mix* ture of various proportions of dark colored bile with the fluids found in the stomach. It differs like- wise most decidedly in taste ; the Black Vomit being always insipid when freed from other foreign mat- ter, whereas the bile can never be deprived of its in- tense bitterness—The above observations have ap. peared to me («< ys Dr. Physick) to overthrow the idea of the Black Vomit being secreted by the liver." Doctor Henry Warren, in his treatise on the Ma- lignant Fever in Barbadoes, (17*0) observes: "That the Fatal Black Stools and Vomitings, are vulgaily supposed to be only large quantities of black bile or choler; which false notion *eems to be owing to that fixed unhappy prejudice that the Fever is purely bil- ious. But any one will soon be undeceived, by dip- ping in a bit of white linen which will be tinged of a deep oloody red, or purple, as I have proved by ma- ny experiments" Dr. Bancroft also says, " That the true explanation of the most common ormation of Black vomit seems to be that it is merely blood, which has been effused from some of the small arteries, and coagulated within the cavity of the stomach, or on the suiface over which it was effused, and having been afterwards detached and triturated by the vio- lent and frequent contractions of that organ, in the ef- forts to vomit, has had its appearance as a coagulum of blood altered, and its color changed by some che- mical decomposition or darkened by the gastric juice." Tib se facts, as they decidedly shew, that there is no bile in the case, likewise necessarily establish that Yel- low Fever never can become a Bilious Disease, and proves in fine, the inconvertibility of the two disor- ders into each other. The Yellow Fever, occurring in, or near to those situations, in which autumnal or Bilious Fevers usually prevail, is a coinciuence, that V»*a l»crl » further pfteft in nmriiiein°r the idea of $i a consimilarity between the two diseases. I have, however, already endeavoured to shew, that the re- mote causes in the two cases are, to a certain extent, distinc ; and that it is a combination of these causes which gives rise to Yellow Fever. I have mention- ed that the effluvia arising from the concentrated pop- ulation of a City, are not sufficient of themselves, to create the latter disease, and that it is only when they come in contact with an unusal mass of mias- mata in the general atmosphere, that the Yellow Fe- ver is produced. That therefore the country must be unhealthy before the town becomes so. When the great body of the air is loaded with those dele* terious exhalations which occasion bilious remittents, the stiperaddition of the various noxious emanations proceeding from an ill cleansed City, necessarily in- genders a malignant disease. Individuals labouring under intermirtents, having been sometimes attack- ed with Yellow Fever, is another misleading circum- stance, which has strengthened the notion of the in- terchangable character of the two disorders;* but this fact, surely proves nothing more, than that during the prevalence of a desolating pestilence persons are not secured against it by the presence of other dis- eases; an impaii ed state of the health, indeed, would only the more readily invite its attacks. Neither does the dreadful Epidemic we are discussing, re- semble any of the Fevers of a Nervous or Typhus type, inasmuch as it is never ushered in by any very decided chills, or rigors, has no remissions or inter- * " As a farther proof of the identity of Yellow and Marsh Fevers* I shad remark that, besides their simultaneous concurrence, and mu- tual interchanges, as before mentioned, they are not unfrequently converted one int» the other, in the very same individual." Bancroft. Never (says Dr. ttush) has the unity of our autumnal t'ever, been more clearly demonstrated, than in our present Epidemic. Its four principal grades* viz. the Intermittent, the Remittent, the Inflamma- tory Bilious Kever, and the Malignant Yellow Fever, have ill run in* to each other in many instances. £2 missions, and never resolves itself bv perspiration, or profuse sweatings, the system seeming quietly to col- lapse and succumb under the force of the disease. It is also especially to be observed, that though it is accompanied by the utmost debility and prostration of strength, the practitioner cannot, as in the fore- mentioned diseases, avail himself of the aid of stim- uli, to arouse, through the medium of the stomach, the dormant and flagging principles of life, being pre- cluded from the use of this class of remedies, by the peculiar iiritability of the stomach, in all Yellow Fever patients, which renders it little less than death, to administer any thing of an exciting or stimulating quality: and though it arises like the Jail, Hospital and Camp Fevers, from the effect of crowded situa- tions, where animal emanations, or human effluvia, meeting with miasmatic principles in the air, favour- able to the production ot disease, return in a mor- bific shape and act deleteriously on the body; it is also widely distinguished from these diseases. It is unnecessary to enumerate the discriminating symp- toms, but the circumstance before alluded to, that of the irritability of the stomach in Yellow Fever, which deprives us of the use of that organ as a point from which, by means of diffusible stimuli, to call into ac- tion the latent energies of life, constitutes a sufficient- ly broad line of demarkation between the respective diseases. In every view then, the Yellow Fever is a disease strictly sui generis^ which cannot run into any other, or any other into it; neither of these oc- currences being any more possible than that Small Pox should become Measles, or the latter he conver- ted into syphilis or Jail Fever. As it is a point gain- ed, to establish what a disease is not, as well as to ascertain its proper diagnostics, I have thought it right to premise thus much, as to the individual and peculiar character of this order, to which a.Protean, S3 or omniformous quality, has been so erroneously ascribed. I shall next offer my views on the subject of its pathology, in which there will necessarily be some blending of theory with facts;, but not to the extent of substituting mere speculation for reasoning and the results of experience. wwv\ wvw\iw\ - bid secreting action, and thus creating disorder throu;.i- out the .whole animal econ nny, I consider in a »vord, as the disease itself, constituting a peculiar vascular affection, to which I should apply the term clonus Vascularis, as more appropriate ihan any otner desig- nation which it has yet received. Toe broken do.vn and disintegrated state of the blood, which is remark- ed in all genuine ca^es of the Fever, probably ex- cites in the first iosta ice, and at any rate sup dies and keeps up the viSluted secretions winch have been described: It is not perhaps given to us, to live in- to the cause of this singular condition of the vital flu- id, but our ignorance in this respect may not oe of much consequence, if it can be shewn that it does not prevent the successful treatment of the disorder, which is what I hope to do in the course of the present un- dertaking. The different effects of climate will never perhaps be satisfactorily accounted f»r; we see its impression sometimes manifested in the disorder of paiticular Viscera, as of the li\er, in many instances ; and thus in Yellow Fever, the lesser blood vessels ap* pear to be specifically acted upon. If the doctrine be admitted, that the whole onut of the disease, falls ex- clusively on the vascular system, not only may most of the symptoms which present themselves in its pro- gress, but also the appearances which are exhibited on the dissection of the Yellow Fever subject, be readily traced to an iutdliginle origin The secre- tions entered into by the blood vessels of thestomach, by ultimately occasioning the engorgement and disten- tion of those organs, would necessarily produce a thickening and enlargement of the coats of i he st omacti itself, and thus give rise to its peculiar in ita iiity which forms the most distressing and uiimauagabie D 26 symptom of the complaint. A similar process go- ing on in the sanguineous vessels dispersed through the substance of the brain, will account for the stu- por and other cephalic affections, and particularly for the dreadful delei ium, and those paroxysms of vi- olence which characterise the more fatal and malig- nant cases The remarkable suspension of all the natural secretions which occurs so early in the Fe- ver, adds, I conceive, a vei\v strong corroboration to these views, as it takes place simultaneously with those unhealthy secretions, commenced in the lesser blood vessels. The functions of the liver seem to- tally suspended, while the dryneis of the fauces and paucity of urine, throughout the attack, indicate a like non-performing state of the kidnies, and saliva- ry glands. The inertness of the skin, also deserves our very particular attention, as it is greater in this than any other form of Fever whatever, the disease never resolving itself by perspiration, or any critical discharges from the surface. The brain, which is to all intents and purposes, a secerning organ, as it se- parates from the mass of the blood ihe nervous flu- id, to distribute and circulate it through tne system, partakes in like maimer of this general suppression of the natural secretions. The excessive debility and prostration of strength, so conspicuous in all cases, must be ascribed to an interruption of the supply of the Fis-Fitalis, or nervous influence, on the due dis- pensation of which all the healthy aciions and vigor of the system seem essentially to depend. The in- fluence of the nervous over the arteiial system, is admitted by all Pathologists, and where we have, as in this epidemic, but little Fever, with a fatal debility and prostration of strength, the office of the brain must be supposed, to be materially interrupted, if not nearly suspended. 27 The last circumstances which I shall deem if ne- nessary to notice, in considering t is part ot the sub- ject, are those profuse hemorrhages, both extern 1 and internal, which mak«* their appearance in the last stage of the disease. The origin of thes« is obvious, a« cording to the foregoing ideas. A necessary ef- fect of the inordinate secretions, which I attribute to the minuter blood vessels, would be the over disten- tion and final rupture of their extremities, resul in* in those discharges of depraved blood from the sto- mach, and also from the fauces, nose, ears, and eve- ry esmunctory of the body, which generally termin- , ate the catastrophe of the disorder. The short parox- ysm of Fever, wiih which patients are at first attack- ed, is only to be regarded as a transient struggle of the vis-rnedicatrix of the constitution, against that un- due action in the smaller sanguineous^organs, which I nave indicated as the primary source of the disease. Idle indication of cure to be drawn from the survey here taken, after a short description of the symp- toms, as they hive presented themselves to my obser- tion, will form the subject of another chapter. SYMPTOMS. Toe particular time at which persons are attack- ed, seems first deserving of notice. I his is gene- rally just before day break, at the period when the collapse of sleep is probably most complete. The seizures which occur thus early, I have observed to be usually more severe, and are more apt to termi- nate fatally, than such as take place in the forenoon, tor persons are rarely attacked at any other than these periods, in the twenty four hours. In the first in- stance the patient often awakes in violent tormina, effecting the stomach and bowels, winch ^ecuis to 28 pusnend, or put off the febrile action, for it is not un- til the decli le of the pain that the fever commences. In common, however, the symptoms are such as have often been described; namely a sense of lassi- tude with ►pain of the head, back and limbs, accom- panied by nausea, and uneasiness of the stomach. The fever sometimes immedia'cly succeeds these af- fertio: s. at others it is ushered in by an obscure chill, or slight rigor. The arterial action is considerable, attended bv a parched state of the skin, with flush- ins of tha f ce. and redness of the eyes—the last however is not an invariable symptom. The pulse is in most casese tense and strong, but in a lew in- stances, irregular and oppressed, while the tongue con'ii-lies eh an and gummy, being very seldom foul or covered with a white furr. The patient always compl tins of (treat oppression of the Piaecordia, and is exceedingly dispirited, sighs much and is often af- fected with slight deleriuin or wanderings of intel- lccr. I hese symptoms are lollowed by frequent retchings, ami the discharge of various foul mat- ters from the stomach, the chief of which seems to be a bilious saburra, which is probably always more or less accumulated in the first passages In these vomi- t:ons pure bile is sometimes thrown up, but which, as h isb» en shewn, has nothing to do with the disease, be- ing caused altogether by the violence of the efforts to vomit, which has the tfleet of emulging the biliary (uct, as often happens in cases of common sea sickness Flatulence is another distressing symp- tom, wiiich set ins to be confined wholly to the sto- mach, and though the patient appears to be often on the point of getting rid of it by ucteration, a rtgurgi a- tioii t«> the stomach takes place, and this wind or gas- tric gass thus continues to undul.de, creating giet distussand restlessness. The paroxysm seld >m ex- tends bey ona thirty-&ix hours, though ii may be pro- 29 traded to fortv in a few instances. Its subsidence, which is never marked by any critical or perspirato- ry discharge, is succeeded by a remarkable quies- cence, and in fact collapse of the whole system. The pulse becomes equable and natural, the ski?) relaxed and cold, the intellect clears up, and the patient ap- pears to be doing well. There is sometimes, how- ever, at this period of the complaint, a stupor, which is always a symptom of great danger—another bad sign, in a moibid irritability of the stomach, manifes- ted by a renewel of the efforts to vomit whenever pressure is made by the hand on that organ. It is al- so a very unfavourable symptom, when the patient expresses an opinion that he is well, or that very lit- tle is the matter with him. The last and most fatal ef- fects of the disease, are an inci eased debility and pros- tration of strength, a sinking of the pulse, and an exarcebation of the irritability, pain, and heat of the stomach, followed by incessant strainings to vomit, and repeated discharges of the black vomit, or stuff resembling coffee grounds, with a dejection of simi- lar dark matters from the bowels. The urine at this time becomes dark and fetid, the yellow suffusion with petechias make their appearance, and hemor- rages from the fauces, nostrils and other external surfaces take place. Finally, the pulse intermits, the breathing becomes laboiious, tie extremities gradu- ally grow cold, and life ceases. The symptoms here detailed, are not, it is to be observed, invariable ei- ther in order or occurrence. Patients often die with- out either the hemorrhages, black vomit or yellowness of the skin. I he last-mentioned peculia ity some times shews itself immediately on the decline of the fever, and may always be regarded as a certain pre- cursor of the formation of the black vomi*. In the early part of the season, the cases usuallv terminate on the fourth day, (leckoning always the natural day 30 of twenty four hours.) As the season advances, they extend themselves to the sixth day, when the worst symptoms appear on the fifth. Towards the end of the summer, the disease is sometimes protracted to the eighth and thirteenth days; during this long col- lapse, the patient generally remains perfectly quiet, though very much prostrated, ex ept where injudici- ous attendants tamper with the stomach, by impro- per administrations, and bring on the vomiting and other afflicting symptoms. Although, as I have before observed, this disease is dissimilar from every other whatever, it is yet sus- ceptible of a certain degree of modification, as we have*sub-grade of it, which in a majority of cases, eventuates' favorably on the third day, by perspira- tion, and is never accompanied by the Black Vomit, Hemorrhages, or any of the more violent symptoms. This nnld torm of the Fever, is capable however of being exasperated into a serious disease, by impro- per treatment, particularly by the administration of mercury, which being an excitant of secretion, brings on all the fatal affections which characterize the higher grade of the Fever. In connection with this part of the subject, it is proper to observe, that strangers are frequently seized in the early part of the season, with Bilious remitting and intermitting Fevers, and though where they recover from these, they are less likely to have the Yellow Fever, they are still liable to take it, by improper exposure or ex- citement of the system. As persons in this climate can never have the disease but once,* there can be * In the first part of these numbers, I endeavoured to account for the liability of Natives to the disease, in the more Northern Cities. In this 1 have yielded to the authority of Physicians in those places, who have so reported the fact. 1 am, however, strongly inclined to doubt, whether an adult, who has once passed through a Yellow Fever summer, or through the disease itself, is ever subsequently in vers or pyrexial disorders ; and in the Clinical Re- ports, also, of the E iinburgb Royal Infirmary, tha s.divating practice is condemned in this cla-s of dis- eases. The writers on this side of the question, have reduced their doctrine to the following axi »m:—•• lb t the Mercu'ial unsusceplibility of the system, is in the ratio of the concentration of the disease;" or in other words, that it is only in the milder grades of fe- ver that Mercury acts as aayllagogue, (which, there- fore, could be cured without it), while in cases of a moie violent type, it proves totally inert. I need not urge that these opinions are deserving of serious at- tention, not only on account of the authorities on which they rest, but also from the intrinsic impor- tance of the subject. The lasting injury often done to the constitution by Mercury, is certainly a consideration which ou^ht to lead to its disuse, in every instance in which it is proved, that the disease can be conquered by other and more innocent means. Without, however, go- ing the length of the writers here cited. I shall con- fine myself solely to the consideration of the Mercu- rial Practice in Yellow Fever; and shall oppose it, first upon the principle just noticed, that of the insus- ceptibility of the system, to the Mercurial impression, in all concentiated cases; and next, on the ground of the excitive effects of Mercury on the secretory organs, the primary affection of which, I consider as forming the foundation of the disorder. The de- bility vvnich it induces, is another objection, which 44 will he urged, a«t prostration and weakness, consti- tute the leading difficulties which we have t> con ten J with in t;,e course of the disease. Dr. Bancroft, on the first point observe*, " I am not convinced of the supposed benefits of Mercury in this complaint; for should it even be the case, as is pretended, that the patients in whom a salivation can he excited, generally recover, I do not perceive that we could thence f.tirly infer, that their recovery was effected by the saliva- tion. It is well known that in many cases, more than 500 and in some more than a lOUO grains of Calomel have heen given internally to a single patient, without producing any sensible eff ct on the salivary glands, or even on the intestines; and although, to explain this inactivity of the Mercury, it has been supposed that in such cases the absorbents alone were in fault, by not taking up the Mercury; this explanation cannot be admitted, because the intestines have been as lit- tle excited by the calomel thus introduced as the sa- livary glands; and it seems, therefore probable, that a general torpor, or defect ot excitability, and of vi- tal energy, existed in such patients, and that the Mer- cury proved inefficacious in them only because they bad aire xdy made considerable approaches towards the condition of a dead body, in which it is obvious that no quantity of (hat medicine however large, could exercise a stimulant power, if ti.is reasoning be just, there will be room to suspect at least, if not to con- clude, that when patients die of the Yellow Fever, af- ter all attempt to excite salivation in them have fail- ed, their deaths have resulted, not from the want of any good effect which salivation may be thought ca- pable of producing, but becatise the condition of their living or sensorial power, and of the functions depend- ing luereon, had already become so morbid as to ren- der tneir recovery impossible: and on the other hand, tn«a where peisons ha\e recovered from the Yellow 45 Fever after having been salivated, their recovery wn» not occasioned by the salivation, but was the conse- quence of such a condition of the powers of life, and of the functions connected therewith, as induced a mi- tigation of the disorder ;* for the same reason, and perhaps, coetiris paribus, in the same degree, as it favoured the operations of mercury upon such per- sons ; and therefore that although recovery has not unfrequently followed, or accompanied salivation, the latter was not a cause of the former. There is no source of error more common or productive, than that of supposing an event which closely follows another to have been occasioned by it; and it may be doubted whether a great number of the advocates for mercurial salivation in the Yellow Fever have any other, or better foundation, for their conviction of its efficacy. In order to attain the truth upon this im- portant subject, we must ascertain whether those practitioners who excite salivation in as many of their patients as may be susceptible of it, do in fact lose a smaller proportion of them than those who purpose- ly abstain from all endeavours to produce that dis- charge : and on this point I must declare that, after some experience, assisted by no ordinary portion of enquiry and information, I have not been able to dis- cover that the salivators have been more successful than the others; and, if not more successful, their prac- tice has certainly been hurtful; because, in most ol the persons who have recovered, the (perhaps useless) salivation had retarded the convalescence and produ* * Dr. Rush has recorded facts illustrative of this idea, but being ignorant of the above principle, did not know how to apply them. He says in his account of the Bilious Fever of '94, *' Mercury seldom sa- livated until the fever intermitted or declined. I saw several cases in which the salivation came on during the intermission, and went oil' during its exercertation, and many in which there .vas no salivation, until the morbid action had ceased altogether in the blood vessels br the solution of the fever." 4« • ceo* troublesome affections of the tonsrue, month and throat, with other ill consequences, as is well known, and acknowledged, even by its advocates. Dr. Rush has candily'stated, that in the City Hospital of Phila- delphia, where bleeding was sparingly used, and where the physicians depended chiefly upon salivation more than one half died of all the patients who were admitted. Dr. David Grant, of Jamaica, avers that " although he attended many under salivation, not one survived, and that they became more the victims to the mercury than even to the Fever."" Dr. Shepherd concludes his essay with remarks to the same effect: be says, " It may appear, pet haps, fastidious, thus to inipugn the truth of a doctrine so plausibly con. stituted, as to hinge on the imposing coincidence of a declension of fever, and the supervention of sali- vation. But in conclusion, I must repeat my belief, for the reasons above assigned, that the reputation of mercury in fever, has been derived from a fala- cious source, that when its uncombined exhibition has been followed by salivation and recovery, the disease has been of a mild grade, which would have yielded to ordinary measures with greater prompti- tude than to mercury alone, witboutthe inconvenience of the consecutive salivation, and that where it has been associated with depletion and other evacuants, the extinction of Fever has been effected by those remedies, and not by the specific operation of mer- cury ; the system under fever, being susceptible of that effect, only when the violence and danger of the disease have been removed, by such effectual prepa- ration." These opinions receive still further sup- port, from a quarter where most experience has been bad upon the subject. Dr. M'Cabe, in his account of the Epidemic Fever of Trinidad, in 1817, makes the following statements: * To doubt the efficacy of mercury in the cure of the Fever of the West' In- 47 dies, may appear extraordinary; the following elr. cumstances, however, together with an impartial at- tention to its effects, induce me to doubt whether mercury is entitled to the great praises bestowed on it in this disease, and the reliance placed on it to the almost total exclusion of other remedies. That the action of mercury does not supersede the action of fcver, every Medical Officer must have seen, who has ha I charge of a hospital in the West Indies. There may be frequently seen patients dying of fe. ver while under the iniuence of mercury; the fatal termination of the disease will there be observed to take place during every stage of the effects of this medicine, from a slight soreness of the gums, to the most seturated stage of Ptyalisra. I have seen persons using mercury for the. cure of other disea- ses, and when Ptyalism was present, attacked with Fever and die of it. In such cases it also ap- peared that the progress of putrefaction during the disease, and after death, was even more rapid than n ordinary cases." In the third chapter of this Essay, I have labored to prove, that the disease depends on, and is entire- ly ascribable to a morbid secretion, carried on by the smaller arteries and blood vessels of the system, ac- companied by an almost total suppression of all the natural secretions. The illustrations and arguments which have been used in support of this idea, need not be repeated here ; it is hoped that they are suf- ficiently strong, to warrant some reliance upon the doctrine, and if it be at all correct, the administration of mercury, which directly keeps up the unhealthy actions, which have been indicated as the source of the disease, cannot but be highly hurtful and perni- cious. The modus operandi of mercurial medicines, has been a subject e£ much dispute in medical seu ence, but it seems to be agreed ou all hands, that 48 they act in the first instance, as stimulants uoon the arterial, or sanguiferous system.* This almittel, their more remote effects, may, I think, be explained in the following manner: Mercury is found to dif- fuse itself more extensively than almost any other medicine, with which we are acquainted, permeating the minutest vessels of the system, an I even trans- piring through the pores of the skin, as is evidenced by its producing a discoloration of metals in the pockets of salivated persons Tins penetrating qual- ity, which carries it to the remotest organ of the liv- ing body, while it enables it to excite the excretory glands, and bring on salivation; also occasions it to act upon, and when too profusely used, to destroy the texture of those pellucid and delicate vessels, or com pages of vessels, which form the periosteum. It is in this way, that it denudes the bones and exposes them to disease, or to that mercurial necrosis, so well known to Physicians It is upon the same principle that it operates efficaciously in discussing tumors, nodes and other local affections, when moderately applied. Being conveyed by its diffusibiiity to the most distant parts; it acts upon and ultimately oo- bterates the anomalous organization, fro n which these topical formations take their rise, and at the same time stimulates the sanguiferous system so as 10 excite the veins to more active absorption, en- abling them rapidly to take up the various morbid matters deposited in the above disorders. Di\ Ma- thias, who has written upon the Febris Mercurialis, or Mercurial Fever, which he aptly terms the disease of the remedy, attributes to mercury the power of producing a specific diseased action; it is not there- * I hare purposely abstained from any discussion of Assimilation* Vascular Spasm, and other theories of absorption, as the simple fact, that certain quantities of Mercury ^capable of pervading eve- ry part of ttae living system, is sufficient for my present object. fore difficult to conceive, that its too free exhibition, should result in the destruction of those finely ea- borated vessels which co npose the covering of the bones, and occasion the affections of the alveolar pro- cesses and'other osseous surfaces, winch so common- ly ensue from its indiscreet uSe. Having then no to- nic powers whatever, and operating altogether as an irritant, its administration in Yellow Fever is contra- indicated bv every symptom, but more especially by the particular condition of the stomach, in all cases of the disease. A great portion of the weight of the disorder appears to fall upon this organ, affect- ftig it with a degree of supersensibility, and throw- ing it into a convulsed and irretentive state, which renders the exhibition of so oppressive and irritating a medicine as mercury, both locally and generally injurious. It is important to observe, that while in tl is viscus, the nervous sensibility is unduly accumula- ted, rendering it peculiarly susceptible of the impres- sion of mercury ; throughout the rest of the system, the powers of life are to a remarkable degree pros- trated and suppressed, so that the medicine acts vio- lently upon the stomach, where it does the most harm, but becomes immediately inert, on passing in- to the intestines and primary passages. This at least happens in the worst cases, and in milder attacks, its specific operation upon the secretions, produces sal- ivation, which invariably aggravates the disease, and retards the cure. Its debiiitating effects, form an equally serious objection to its employment in this disease, which is marked by a prostration, and ex- haustion, greater than in any other species of Fever, Dr. M'Cabe, before quoted, speaks, " of having re- peatedly seen calomel thrown in, in large quantities, with the view of inducing the action of mercury in the system, fail in removing the Fever, and greatly increase the fuintness and exhaustion.*' He again says, 00 il T have seen such a degree of faintness and exhaus- tion, succeed to even moderate doses, that the pulse became almost imperceptible, and the other func- tions were equally enfeebled." Its reputation as a preventive, stands on no better foundation than its claim as a cure. That it is not only destitute of pro- phylactic virtues of any sort, but is actually disadvan- tageous to those who take it as a security, and dis- poses them to receive the infection more readily; many instances which have come under my own ob- servation, and others already on record, sufficiently establish. The writer last cited, mentions particu- larly the case of a gentleman, " a great admirer of mercury, who, during the prevalence of a Malignant Fever, by way of securing himself against the dis- ease, took three grains of calomel every day. This gentleman was attacked with Fever aud died." The view with which it is generally given, that of crea- ting a new action, or by one disease, to drive out another, is at once so mistaken, absurd and unme- dical, as scarcely to deserve a serious notice. The above notion that two diseases cannot exist at the same time, in the same patient; the experience of every day proves to be without foundation. Decisive evidence upon this head, might be adduced from vari- ous quarters, but the cases recorded by the respec- table Dr. M'Bride, ought forever to terminate this question. He states that beiween the years 1765 and '67, hundreds of cases of small pox and mea- sles, co-existing in the same person, occured in the Dublin hospitals under his immediate observation; and facts of a similar kind are testified to by other physicians. ••• It is certainly, prima facise, a circtim- * Since writing the above, I have met %vith the following facts brought together Ly Dr. Francis, in his remarks of the modus ope- randi of mercury, " That the human body is susceptible of the ope- 9i Stance unfavourable to the exhibition of any remedy, when it is given with the express intention of crea- torily shewn by the facts recorded by Dr. Patrick Russell, of the small pox and measles which prevailed at Alleppo, in i765. On the author- ity of Bergius and Tandon, mention is made of several cases in which. the measles and small pox appeared together in the same individual. Dr. Willan witnessed the occurrence of hooping-cough (a disease of acknowledged specific contagion) during the eruption of the small pox in the same person; the former disorder remained a long time after the latter without any material alteration Cases of small pox com bined with measles came under the ntice of Dr. Walker. Dessessatts mentions the complication of small pox with scarlatina. Mr Leese inoculated an infant while laboring under measles, and both diseas- eases went through their ordinary course. Two cases winch exhibited unequivocal evidence of the possibility of two distinct diseases, small pox and measles, arising at the same period in the human constitution, and each preserving its ordinary course as when separately existing, attended with all their usual characteristic symptoms, are recorded by Dr Tracy. A number of cases of small pox co-existing with meas? les, and the two diseases, going through their regular stages in the same individuals, occurred at the Foundling Hospital, at Dublin, as appears from extracts from the memoirs of the Medical Society of that city, communicated by Dr. Uainey- All these instances ofthe continued operation of measles with other disorders of specific con- tagion, it will be proper to bear in recollection, are cited from modern authors: the opinions of the more ancient writers on this point being disregarded on account of the errors into which they were led from adopting the principles of the Arabian Physicians, and considering and generally treating these different specific disorders, small pox, measles and scarlatina, as modifications of the same disease. " Mr. Maurice vaccinated two persons who had been previously exposed to measles. The vaccine infection and the measles went through their usual course at the same time. It appeas fro ;» the ob- servations of Dr. Woodville, Dr. WHan and other writers on the cow pox, that if the constitution be submitted simultaneously to the action of the small pox arid the vaccine diseases, that these disorders go through their course at the same time without influencing each other. Many cases of this kind might be mentioned. " In the report of the New-York City Dispensary, published July, 1809, the physician of the cow pox department, recorded the case of a child who, on the eighth day after it was vaccinated, had the vac- cine disease with all its characteristics, and at the same time, labour- ed under a '* plentiful eruption of the small pox," to which disorder it had been exposed by an imprudent visit some days previous. The t ao diseases appeared entirely distinct and independent of each other. The physician vaccinated six children from the fluid of the vesicle, who all had the regular cow pox, and were afterwards te-ted by the small pox inoculation without effect. Several children were inoculated with the matter from the small pox eruption who took the disease in its usual form. Dr. Adams himself, the unqualified and ii.discumi- 58 ting a disease; and an examination into the grounds of this practice will not be found to lessen the ob- jection to it. The idea of creating a morbus medan- tit, or curative disease, carries on the face of it, ab- surdity; for it is plain, that a medicine to do good, must act, sanatively, and where it does not effect this, if it possesses any activity it must do harm; thus the above is not a mere harmless paradox, hav- ing I am persuaded destroyed thousands, for error ai»d evil are indissoluhly connected in the order of cause and effect. Dr. Francis, Professor of Mate- ria JVIedica, in the Medical College of New-York, expresses himself very strongly upon this subject. The following passage is from his pen, and deserves to be pondered upon:—w' At the present time, the practice of salivation seems to owe its general re- ception to the well known principle espoused by Mr. Hunter, that no two morbid actions can exist at tlie same time, and that one irritation destroys another: yet nothing can be more evident, from Mr. Hunter's writings, tban this very method of cure, met in him a derided enemy. It is of minor consideration to be informed of the source which gave origin to this mode of treatment; and, painful indeed, the recol- lection of the miseries it has created No absurdity in medical practice has been the destruction of more lives, none the source of more pain and calamity. Well might Dr. Hoffman pronounce the abuse of this remedy in the hands of the unskillful, to be more ter- rible than the sword. The pages of the older wrt- ters, as well as the modem, fully confirm this fact; yet this method of cure is still popular, still pursu- ed both in private practice and in public institu- tions." Any medicine, indeed, given in the quam nate panegyrist of the doctrines of Mr. Hunter, asserts, that small pox and cw pox ' will proceed together in the same person without the smallest interruption to each ether's course.' " 08 titles in which calomel is usually administered in Yel- low Fever, would produce ill effects, and one half of the injury done by Mercury in this disease, results from the excessive use of it. The remedy I have endeavoured to recommend, the super-acetate of lead, or saccharum saturni, may be said to afford a complete contrast to mercury, in all its effects. It restrains, while the latter promotes secretion, it tran- quillizes instead of exciting the stomach, and sup- ports instead of exhausting the patient. Its effects al- so cease with the disease, while those of Mercury are perpetuated after it, and often become perma- nent. The injuries done by large quantities of mer- cury, are certainly worthy of the consideration of pa- tients, if not of their physicians. The loss or im- pairment of the teeth, the diseases of the bones and other consequences of repeated and profuse saliva- tions, ought to be borne in mind by all who value the blessings of a sound constitution. Dr. Adam Hun- ter, on this point, observes, "salivation with whate- ver care produced, gives a shock to the system, which is not easily got the better of, and the continued in- fluence of the Fever and Mercury call into activity, any latent pulmonic or scrofulous (and he might have added, cancerous,) affections, which is often attended with deleterious consequences."* I have entered in- to the foregoing questions, solely with the hope of throwing some light upon a subject of extensive im- portance to the community, and having discharged the task to the best of my ability, here terminate the discussion. * It might be said, that mercury can seldom be given in Yellow Fe ver, in such quantities as to create the ill effects above enumerated • but it is known, that ounces have in some instances been administer- ed before Ptyalism could be induced ; and as remittents are so often mistaken for Yellow Fever, persons are frequently subjected to repea- ted salivations in the course of the same seasons. Children also require a ireat deal of mercury to salivate them, and when the effect is produced, they suffer more from it than grown persons. 04 Some of the topics perhaps, required to he more enlarged upon, than they have been, but as they em- brace matters of general interest, and the opinions and views presented, are for the most part such as have never before been touched upon, I was appre- hensive that a lengthened or diffuse dissertation might prove repulsive to the majority of readers, and therefore studied the utmost brevity and condensa- tion, and confined the present publication within nar- rower limits than I should otherwise have prescribed to myself. 55 CONCLUSION. tn the commencement of this Treatise, I promts* ed an Appendix which was to contain an abstract, or synoptical view of the state of the question respec- ting the domestic origin of the Fever: I now how- ever deem it unnecessary to swell the present pub- lication with the additional matter I contemplated introducing, as I observe that the subject has been t-.ken up in one of the Scientific Journals of the day, the New-York Medical Repository, in a late number of which, there are several papers relative to the lo- cal production of the disease, and the editors are pleased to quote with approbation the first part of this Essay. One further observation on the subject I Would make, which was omitted in its proper place; it is this, that in the West Indies, the general condi- tion of the air, from the excess of tropical heat and other causes, is always such, that in combination with the deleterious effluvia of their ill cleansed Towns, it occasions" the constant existence of Yellow Fever, and renders it endemic in the sea ports of that part of the World; while in Carolina, from our more tem- perate position as to latitude, the disease is only oc- casional, occuring in particular seasons when inordi- nate heat, moisture and other circumstances prevail, wtiich are favourable to the formation of the fever. I cannot quit the topic, without once more urg- ing upon my fellow-Citizens, the necessity of early directing their most earnest attention towards the ob- ject of improving our police, and to the prompt revi- val and enforcement of the many excellent ordinan- ces which already exist. On the commencement of the summer, I would recommend that Commission- 56 ers should be appointed in every Ward, charged with the duty of looking into and reporting upmi all nui- sances, or local circumstances likely to be injurious, and which they may deem susceptible of removal or remedy. Those selected fortius office, should be from among the most respectable characters in our community, in order that the Citizens might be the more readily re- conciled to the disagreeable domicilary visits, to which theproposed regulations would subject them. One of the Reverend Clergy therefore, (who would no doubt willingly enteron so useful a duty,) should be attach- ed to each commission, and one of the Medical Facul- ty also, who would be able to direct the attention of his associates to the proper objects. Were a plan of this kind zealously pursued, there can be no doubt that the pestilence would either be averted, or mitigated in its effects, and confined in its range A reap plica- tion to the Legislature would also 1 think be expedi- ent, for it is probable that if it were made manifest to that body, that the Medical Faculty of this Country are almost unanimously of opinion that the disease is of domestic formation, and that evident success has attended the exertions made in Philadelphia and New York for its eradication; it would be induced to assist the City with a sum of money towards the object in view. In New York where immense improvements have been made within a few years, the mayor and corporation are invested with powers not given to the Council of Charleston, and which at present can only be exercised by our Legislature itself. The above is in substance, the plan proposed in a late number of the Edinburgh Review, for preventing the recurrence of Typhus Fever which lately desola* ted some parts of the United Kingdom. It is certain- ly simple, and might he readily put in execution. It would be expedient also, to appoint persons to thedu- sy ty of attending to the ventilation of the shipping in the harbour during the Summer. The uncleanliness which generally prevails on board vessels, and the foul air in their holds, contribute very greatly to COD taminate the atmosphere of the city. t ERRATA. 4. i-i Kr,e frr.-n -<>e 'n*' )■•;, .!«.'. t. »;ffWt. 6, ifit'n lint* ti;;n :>r. . !<.-«• . >?-:+nc:''-'t i►nh' <-'j-»centrflt?'i 7. 2d line iVysn t .•.$.'. •,>» //;•. fur -ith r--'a«i 6t/, i.>, bth line ?i -'n botici;. •<>)• ?'vr»n read of. it*, IOth do.
