[4]If the progress of the sweating sickness was similar to that of cholera, the advice of the King to Wolsey was sound; for instead of recommending him to rely on any-thing like cordon systems, or to shut himself up surrounded by his guards, he tells him (seeEllis'sletters) to "fly tocleneair incontinently," on the approach of the disease. I use the wordsapproach of the diseaseoccasionally, as it is a manner of expression in general use, but it is far from being strictly applicable when I speak of cholera;the causeof the disease it is which I admit travels or springs up at points, and not the disease itself in the persons of individuals, or its germs in inanimate substances.

For one piece of tact the author of the letter deserves great credit; for whereas his College collectively, when forming their opinion on the questions proposed to them by the Council, seemed to throw all India records overboard,—he, in his individual capacity, as author of the letter, sends after them all the Russian reports in support of contagion; for anxious as he is to prove his point, not a word do we get of theon ditsso current in Russia about persons being attacked with the disease from smelling to hemp arrived from such or such a place; from having looked at a boatman who had been up the Volga or down the Volga, &c. &c.: all which statements, when duty inquired into, prove to be unsupported by any thing in the shape of respectable authority, and this is now, in all probability, pretty generally known to be the case, as Dr. Macmichael must be quite aware of.
To the medical gentlemen of India who have been concerned in the official reports, which do them,en masse, so much credit, Dr. Macmichael is little disposed to be complimentary; and, indeed, he seems to insinuate that those were rather stupid fellows who did not come to what he is pleased to consider "a just and right conclusion," as to contagion; he thinks, however, that he has got a few of "the most candid" to join in his belief. We shall see whether he had better reason toPt_1[Pg 18]look towards the Ganges and Beema for a confirmation of his doctrines, than he had toward the Don or the Volga. How does the case stand with respect to one of the gentlemen whom he quotes,—Mr. Jukes, of the Bombay Establishment? This gentleman, like all who speak of cholera, mentions circumstances as to the progress of the disease which he cannot comprehend, and Dr. Macmichael shows us what those circumstances are; but Dr. Macmichael does not exhibit to uswhat doescome perfectly within Mr. Jukes's comprehension, but which is not quite so suitable to the doctor's purpose. This omission I shall take the liberty to supply from an official letter from Mr. Jukes in the Bombay Reports:—"I have had no reason to think it has been contagious here, neither myself nor any of my assistants, who have been constantly amongst the sick, nor any of the hospital attendants, have had the disease. It has not gone through families when one has become affected. It is very unlike contagion too, in many particulars." &c.—(Bombay Reports, page 172.)—Ought we not to be a little surprised that so great an admirer of candour, as Dr. Macmichael seems to be, should, while so anxious to give every information to his readers, calculated to throw light upon the subject of cholera, omits the above important paragraph, which we find, by the wayimmediately precedesthe one upon opinions and difficulties which he quotes from the same gentleman? But let us examine what the amount of force is, which can be obtained from that part of Mr. Jukes's paper, which it does please Dr. Macmichael to quote:—"If it be something general in the atmosphere, why has it not hitherto made its appearance in some two distinct parts of the province at the same time? Nothing of this kind has, I believe, been observed. It still seems creeping from village to village, rages for a few days, and then begins to decline." I find myself unable, at this moment, to ascertain the extent of Mr. Jukes's means of obtaining information as to what was passing in other parts of his province; but I think the following quotation, on which I am just now able to lay my hand, will not only satisfactorily meet what is here stated, but must, in the public opinion, be treasured, as it serves at once to displace most erroneous ideas long prevalent, and which, I believe, greatly influenced men's decisions as to contagion:—"It may, then, first be remarked, that the rise and progress of the disorder were attended by such circumstances as showed it to be entirely independent of contagion for its propagation. Thus we have seen that it arose at nearly one and the same time in many different places, and that in the same month, nay, in the same week, it was raging in the unconnected and far-distant districts of Behar and Dacca." (Bengal Reports, p. 125.) Again (p. 9), that in Bengal "it at once raged simultaneously in various and remote quarters, without displaying a predilection for any one tract or district more than for another; or any thing like regularity of succesion in the chain of its operations." In support of what is stated in these extracts, the fullest details are given as to dates and places; and at page 9 of those Reports, a curious fact is given, "That the large and populous city of Moorshedabad, from extent and local position apparently very favourably circumstanced for the attacksPt_1[Pg 19]of the epidemic, should have escaped with comparatively little loss, whilst all around was so severely scourged." This seems to have been pretty similar to what is now taking place with respect to the city of Thorn, which remains free from cholera, though the communication is open with divers infected places in every direction. Should Thorn still be attacked by the disease (as it sooner or later will, in all human probability), the contagionistspar métierwill try to establish a case of hemp or hare-skin importation, I have no doubt. I wonder much that Dr. Macmichael or Dr. B. Hawkins, when favouring us with eastern quotations, did not give the public the opinion of Dr. Davy, who is so well known in Europe, and who saw the cholera in Ceylon; his conjecture (quite accessible, I believe, to every medical man in London) may perhaps be as valuable as that of any other person. The following is a copy of it:—"The cause of the disease is not any sensible change in the atmosphere; yet, considering the progress of the disease, its epidemic nature, the immense extent of country it has spread over, we can hardly refuse to acknowledge that its cause, though imperceptible, though yet unknown, does exist in the atmosphere. It may be extricated from the bowels of the earth, as miasmata were formerly supposed to be; it may be generated in the air, it may have the properties of radiant matter, and, like heat and light, it may be capable of passing through space unimpeded by currents; like electricity, it may be capable of moving from place to place in an imperceptible moment of time." Dr. Davy is an army physician, and the report of which this is an extract, may be seen at the Army Medical Office, a place which, of late years, has become a magazine of medical information of the most valuable kind in Europe. There is this difference between army and other information on cholera, that (whether in the King's or E. I. Company's service) the statements given by the medical gentlemen have their accuracy more or less guaranteed by a certain system of military control over the documents they draw up: thus, in the circumstance already noticed as having occurred in the 14th regiment, we have every reason to rely upon its accuracy, which we could not have in a similar statement among the population of any country; and we have, I think, no reason to believe that in pronouncing the cholera of Ceylon not contagious, Dr. Davy, as well as two other gentlemen of high character and experience (Drs. Farrel and Marshall), have not gone upon such data as may bear scrutiny.
Having given, in my last letter, Dr. Davy's views as to the cause of cholera, I may so far remark just now regarding them, that they are not new, or peculiar to him; and that it may be well, before Dr. Macmichael or others pronounce them vague, that they should inquire whether some of those causes have not been assigned for the production of certain epidemics,Pt_1[Pg 20]by one of the soundest heads of Dr. Macmichael's college—Dr. Prout, who seems, if we have not greatly mistaken him, to have been led to the opinion by some experiments of Herschell, detailed in the Philosophical Transactions of the year 1824. They should recollect that other competent persons devoted to researches on such subjects (Sir R. Phillips among the number) admitspecific local atmospheres(not at allmalariain the usual sense of the term), produced by irregular streams of specific atoms from the interior of the earth, and "arising from the action and re-action of so heterogeneous a mass." For my part I feel no greater difficulty in understanding how our bodies, "fearfully and wonderfully made" as we are, should be influenced by those actions, re-actions, and combinations, to which Sir Richard refers, and of "whose origin and progress the life and observation of man can have no cognizance," than how they are influenced by other invisible agents, the existence of which I am compelled to admit.—If the writer of the article on cholera in theWestminster Review, for October, 1831, do not find all his objections met by these observations, I must only refer him to thequid divinumof Hippocrates:—but I must protest against logic such has been employed by certain members of our Board of Health, who lately, on the examination of gentlemen of the profession who had served in India, and who had declared the disease not to be communicable, came to the conclusion that it must, nevertheless, be so, as those gentlemen could not showwhat it wasowing to.
Most extraordinary certainly it does appear, that while Dr. Macmichael goes to the trouble of giving us (p. 27) the views ofa captain(!) as to the progress of cholera at a certain place in India, he should have refrained altogether from referring, on the point of contagion or non-contagion, to the report of such a person as Dr. Davy, or to the reports of this gentleman's colleagues at Ceylon, Drs. Farrell and Marshall. Had Dr. Macmichael added a little to his extract from Capt. Sykes, by informing us of what that gentleman states as to the great mortality ("350 in one day") in the town of Punderpoor, "when the disease first commenced its ravages there," people would have means of judging how unlike this was to a contagious disease creeping from person to person in its commencement.
It is painful to be obliged to comment on the manner in which Dr. Bisset Hawkins has handled the questions relative to the Ceylon epidemic, which seems far from being impartial; for, while he quotes (p. 172) Dr. Davy, "a medical officer well known in the scientific world," as stating that the cause of the disease is not in anysensiblechanges in the state of the atmosphere, he breaks off suddenly at the wordatmosphere, proceeds to talk of the changes in the muscles and blood of persons who die of the disease, and passing over the part quoted from Dr. Davy, near the close of my last letter, Dr. Hawkins leaves his readers to draw a very natural conclusion—that, as Dr. Davy admitted that there were no prevalentsensiblestates of the atmosphere to which the cholera could be attributed,he, therefore, believed it to have been propagated by contagion, an inference which we now see must be quite wide of the mark. Dr. Hawkins had, it appears, like many other medical gentlemen, access to thePt_1[Pg 21]reports from Ceylon, &c., in the office of the chief of the army medical department in London, and it is to be regretted I think that, with respect to one of the Ceylon reports, he only tells us (p. 174) that "Mr. Staff-Surgeon Marshall reports from Candy, that of fifty cases which had occurred, forty died." Why more had not been quoted from a gentleman who had such ample means of witnessing the disease in its very worst form, I must leave to others to say; but, referring again to the highly interesting letter from Mr. Marshall on cholera, which appeared in theGlasgow Herald, of the 5th of August last, and in which, from many important observations which every body interested in cholera should read and study, the following remarks will be found:—"In no one instance did it seem to prevail among people residing in the same house or barracks, so as to excite a suspicion that the contact of the sick with the healthy contributed to its propagation." "The Indian Cholera, as it is sometimes called, appears not to be essentially different from cholera as it occurs in this and all other countries." "I consider it, therefore, impossible for a medical practitioner to speak decisively from having seen one, or even a few cases of cholera in this country, and to say whether they are precursors of 'the epidemiccholera' or not. That the disease is ever propagated by means of personal contact, or by the clothes of the sick, has not, as far as I know, been satisfactorily proved. The quality of contagion was never attributed to the disease in Ceylon, and I believe no-where did it occur in greater severity. I am aware that an attempt has been made to distinguish the ordinary cholera of this country from the 'epidemic cholera,' by means of the colour or quality of the discharges from the bowels. In the former it is said the discharge is chiefly bile, while in the latter it is said to bear no traces of bile, but to be colourless and watery. How far is this alleged diagnosis well founded? I am disposed to believe that, in all severe cases of cholera, whether it be the cholera of this country, or the epidemic cholera, the secretion of bile is either suppressed, or the fluid is retained in the gall-bladder." Mr. Marshall, it may be observed, is the gentleman who was selected by the late Secretary at War, in consequence of his known intelligence, to remodel the regulations relative to military pensioners; and I understand that, in consequence of the manner in which he executed that very important duty, he has since been promoted. After what appears from the above quotations, how perfectly unwarrantable must the assertion of Dr. Bisset Hawkins seem, that "from the Coromandel coast it seems to have been transported by sea to Ceylon!"
We shall, I think, be able to see that the assumption of Drs. Macmichael and Hawkins, as to the importation of the disease into the Mauritius from Ceylon, is equally groundless with that of its alledged importation into the latter island; and here we have to notice the same want of candour on the part of those gentlemen, in not having furnished that public, which they professed to enlighten on the subject of cholera, with those proofs within their reach best calculated to display the truth; be it a part of my duty to supply the omissions of these gentlemen in this respect. The following is a copy of a letter accompanying the medical commissionPt_1[Pg 22]report at that island forwarded to General Darling, the then commanding officer, by the senior medical gentleman there.
"Port Louis, Nov. 23, 1819.
"I have the honour of transmitting the reports of the French and English medical gentlemen on the prevalent disease; both classes of the profession seem to be unanimous in not supposing it contagious, or of foreign introduction. From the disease pervading classeswho have nothing in common but the air they breathe, it can be believed that the cause may exist in the atmosphere. A similar disease prevailed in this island in 1775, after a long dry season."

W. A. Burke,Inspector of Hospitals.
In the reports referred to in the above letter, there is the most ample evidence of the true cholera having appeared at different points in the colonybefore thearrival of the Topaze frigate, the shipaccusedby contagionistspar métier, of having introduced the disease; so that, contrary to what Dr. Macmichael supposes, those who disbelieve the communicability of cholera, have no necessity whatever in this case for pleading a coinsidency between the breaking out of the disease, and the arrival of the frigate; indeed, his friend Dr. Hawkins seems to be aware of this, when he is obliged to have recourse to such an argument as that "it is, at all events, clear that the disease had not beenepidemicat the Mauritius before the arrival from Ceylon;" so that the beginning of an epidemic is to be excluded from forming a part or parcel of the epidemic! Why is it that in medicine alone such modes of reasoning are ever ventured upon!
We know, from the history of cholera in India, that not only ships lying in certain harbours have had the disease appear on board, but even vessels sailing down one coast have suffered from it, while sailing up another has freed them from it, without the nonsense of going into harbour to "expurgate." Now, with respect to theTopaze, it appears that while lying in harbour in Ceylon, the disease broke out on board her; that after she got into "clene air" at sea, the disease disappeared, seventeen cases only having occurred from the time she left the island, and she arrived at the Mauritius, as Dr. Hawkins admits, without any appearance whatever of the cholera on board. On the day after her arrival, she sent several cases ("chronic dysentry, hepatitis, and general debility") to hospital, but not one of cholera; neither did any case occur on board during her stay there, at anchor a mile and a half from shore, and constantly communicating with shore,[5]while a considerable number of deaths took place from cholerain the merchant vessels anchored near shore.
[5]Somebody is said to have seen a man on board with vomiting and spasms, on the day before she moved to this anchorage, but the surgeon of the ship has not stated this.

Pt_1[Pg 23]As to the introduction of cholera from the Mauritius into Bourbon, where it appeared but very partially, Dr. Macmichael very properly does not say one word. There was abundance of "precaution" work, it is said, and those who choose, are at liberty to give credit to the story of its having been smuggled on shore by some negro slaves landed from a Mauritius vessel. As to theprecautionsto which the writer inThe Westminster Reviewattributes the non-extension of the disease in this island, hundreds of instances are recorded, in addition to those which we have already quoted, of the disease stopping short, without cordons or precautions of any kind—one remarkable instance is mentioned by Dr. Annesley, where,without seclusion, the disease did not reach the ground occupied by two cavalry regiments, although it made ravages in all the other regiments in the same camp.
We have, perhaps, a right to demand from those gentlemen who display such peculiar tact in the discovery of ships by which the cholera has, at divers times, been imported into continents and islands, the names of those ships which brought to this country, in the course of the present year, the "contagion" which has produced, at so many different points, cases of severe cholera, causing death in some instances, and in which the identity with the "Indian cholera," the "Russian cholera," &c., has been soperfect, that all the "perverse ingenuity" of man cannot point out a difference. If it cannot be shown that in this, we non-contagionists in cholera are in error, people will surely see reason for abandoning the cause of cordons, &c., in this disease,—a cause which, in truth, now rests mainly for support upon a sort of conventional understanding, unconnected altogether, it would appear, with the facts of the case, and entered into, we are bound to suppose, before the full extent of the mischief likely to arise from it had been taken into consideration. Admitting for a moment that a case of cholera possessing contagious properties could be imported into this country this year, will anybody say that a "constitution of the atmosphere" favourable to its communicability to healthy individuals, has not existedin a very high degree:—can a spot be named in which cholera, generally of a mild grade, has not prevailed? And if contagionists cannot point out a difference between some of the severe cases to which public attention has been drawn, and the most marked cases of the Indian or Russian cholera, I think that now there should be an end to all argument in support of their cause. Without at all going to the extent which might be warranted, I would beg to be informed of the names of the ships by which the contagion was brought, which caused the illness of the following individuals; or if they be allowed, as I presume must be the case, not to have been infected at all in this way, all that has been said regarding the identity of the foreign and severe form of the home disease, must be shown to be without foundation:—the detailed case of Patrick Geary, which occurred in the Westminster Hospital,—the fatal case of Mr. Wright, surgeon, 29, Berwick-street,—the cases, some of them fatal, which occurred at Port Glasgow, and regarding which, a special inquiry was instituted,—a case in Guy's Hospital, which caused some anxiety aboutPt_1[Pg 24]the middle of July last,—a case reported in a medical periodical in August last, as having occurred in Ireland,—the fatal case, as reported in my first letter, of Martin M'Neal,[6]—a second case reported in a medical periodical in August,—a fatal case on the 12th of August last at Sunderland, reported upon to the Home Secretary by the mayor of that town,—three cases reported in No. 421 ofThe Lancet,—a very remarkable case duly reported upon in September, from the Military Hospital at Stoke, near Davenport, and a case with thorough "congee stools," spasms, &c. (the details of which I may hereafter forward), which occurred at Winchester on the 22d of September, in the 19th Foot, in a man of regular habits, and ofthe natureof which case the medical gentleman in charge had no doubt.
[6]The same Army Medical gentleman, who had been sent to Port Glasgow, was sent to Hull to report upon this case:—he arrived there too late, but having seen the details of the case, he admitted that he saw no reason to declare them different from those which occurred in the Indian cholera.

I quite agree with those who are of opinion, that in this and most other countries, cases may be every year met with exhibiting symptoms similar to those which have presented themselves in any one of the above. Instead of amusing us, when next writing upon cholera, with a quotation about small-pox from Rhazes, bearing nonsense upon the face of it, some of those who maintain the contagious property of Indian or any other cholera, may probably take the trouble to give the information on the above cases, so greatly required for the purpose of enlightening the public.
I must now beg to return to an examination of one or two more of thevery selectquotations made by Dr. Macmichael, with the view, as he is pleased to tell us, of placing the statements on both sides in juxtaposition. He is well pleased to give us from Dr. Taylor, assistant-surgeon,—what indeed never amounted to more than report, and of the truth or falsehood of which this gentleman does not pretend to say he had any knowlege himself,—that a traveller passing from the Deacan to Bombay, found the disease prevailing at Panwell, through which he passed, and so took it on with him to Bombay; but whether the man had the disease, or whether he took its germs with him in some very susceptible article of dress, is not stated by Dr. Taylor; however, he states (what we are only surprised does not happen oftener in those cases, when we consider similarity of constitution—of habits—of site or aspect of their dwellings, &c.) that several members of a family, and neighbours "were attacked within a very short period of each other;" but when Dr. Taylor goes on to say, "In bringing forward these facts, however, it may be proper at the same time to state, that of the forty-four assistants employed under me, only three were seized with the complaint;" he gets out of favour at once, and his observation is called "unlucky," being but anegativeproof, and Dr. Macmichael adds, what everybody must agree with him in, that positive instances of contagion must outweigh all negative proofs:—to be sure:—but Dr. Macmichael's saying this, does not show that positive proofs exist. Give us but positive proofs, givePt_1[Pg 25]even but afew, which surely may be done, if the disease be really communicable, and where contagion has been so ardently sought after by all sorts ofattachésandemployésof the cordon and quarantine systems in the different countries on the Continent. We could produce no mean authority to show, thata long succession of negative proofsmust be received as amounting to a moral certainty; and what greater proof can we have of non-contagion in any disease, than we have in the fact regarding epidemic cholera, as well as yellow fever, that attendants on the sick are not more liable than others to be attacked? Regard should, of course, always be paid, in taking this point into consideration, to what has been already noticed in my second letter, or the inferences must be most erroneous. Dr. Macmichael quotes the statement of Dr. Burrell, 65th regiment (and takes care to put the quotation in italics too), that at Seroor, in 1818, "almost every attendant in hospital had had the disease. There are about thirty attendants in hospitals." Now, along with hundreds of other instances, what does Dr. French, of the 49th regiment, say, in his Report of 1829? That no medical man, servant, or individual of any kind, in attendance on the sick, was taken ill at Berhampore, when the cholera prevailed there that year, and refers, to his Report for 1825, in which he remarked the same thing in the hospital of the 67th regiment at Poonah; contrary, as he observes, to what occurred some years before in the 65th regiment at Seroor, about forty miles distant. In the two instances quoted by Dr. French, and in that by Dr. Burrell, all those about the sick stood in the same relation towards them, and all the difference will be found probably to have been, that the hospital of the 65thwas within the limit of the deteriorated atmosphere, where the cause existed equally (as in the case of ague and yellow fever) whether persons were present or not.
In Egypt there is not, it is true, a "cruel and inhuman desertion" of the unfortunate plague patients; for, among other reasons, being predestinarians, they think it makes no sort of difference whether they attend on the sick or not. Those who act upon the principle of cholera being a highly contagious disease, may perhaps consider it necessary to recommend, among theirprecautions, that the medical men and attendants should be enveloped in those hideous dresses used in some countries by those who approach plague patients[7]—fancy, in the case of a sick female, or even of a man of pretty good nerves, the effect of but half the precautions one hears of, as proper to be observed. It is quite a mistake to suppose that the sick have not been sometimes abandoned during the prevalence of epidemics; and that too in cases where medical men had very erroneously voted the disease contagious:—among other horrid things arisingPt_1[Pg 26]out of mistaken views, who that has ever read it, can forget the account given by Dr. Halloran, of the wretched yellow-fever patient in Spain, who, with a rope tied round him, was dragged along for some distance by a guard, when he was put into a shed, where he was suffered to die, without even water to quench his thirst? I admit that, even with the views of non-contagionists, difficulties obviously present themselves in regard to the safety of those about the sick, when the latter are in such a state as will not admit of their removal to a more auspicious spot from that in which there is reason to believe they inhaled the noxious atmosphere. From what has been observed in India and other places, however, there is often sufficient warning in a feeling ofmalaise, &c., and the distance to favoured spots, where people may be observed not to be attacked, may be very short,—sometimes, as we have seen, but a few yards, so that a removal of the patient,with his friends, may be practicable, in a vast number of cases, previous to the setting in of the more serious symptoms.
[7]Since writing the above, I find that this scene has actually occurred lately at Dantzic where a few miserable medical men illustrated their doctrines of contagion, by skulking at a certain distance about the sick, dressed up in oil skins, like the disgusting figures we see in books, of the Marseilles doctors in the Lazaretto. (See Sun Newspaper, 22nd, Nov.)

(See Sun Newspaper, 22nd, Nov.)
I shall conclude this by cursorily referring to two circumstances which have within a short time occurred on the Continent, and which seem to me to be of no small importance in regard to cholera questions. It appears that the committee appointed by the French Chamber of Deputies to inquire into the questions connected with voting an additional sum to meet cordon and quarantine expenses, in the event of the cholera making its appearance in or near France, have made their report to the Chamber. They declare that in India the cholera was proved not to have been transmissible; and that in regard to Russia, it was not introduced, as always contended for by some persons:—they refer to the city of Thorn as exempt from the disease, though free from cordons, and in the midst of a country where it prevails, while the disease appeared in St. Petersburg and Moscow, notwithstanding their cordons, and even in Prussia, where sanatory laws where executed "avec une punctualité et une rigeur ailleurs inconnues." The money is nevertheless granted; it is always a good thing to have, but they have set one curiousconditionupon its being granted, which displays consummate tact, for it is to be employed solely in disbursements of a particular nature (dépenses materielles), including, it may be presumed, temporary hospitals, &c.; and that it is by no means ("nullement") to go into the pockets of individuals.
The other circumstance to which I allude is that, like Russia and Austria, Prussia has found that quarantines and cordons do not check the progress of cholera. The king declares that the appearance of the disease in his provinces, has thrownnew lighton the question; he specifies certain restrictions as to intercourse, which were forthwith to be removed, and declares his intention to modify the whole. In short, it is quite plain that, as Dr. Johnson has it in his last journal,—those regulations will, "in more countries than Russia, be useless to all but those employed in executing them."
Pt_1[Pg 27]
It need scarcely be said how much it behooves all medical men to keep in view the subject of the wide-spreading cholera, and not to suffer themselves to be led from an attentive consideration of all that appertains to it, by the great political questions which at present convulse the whole kingdom.
I totally disagree with Dr. Macmichael, as I believe most people will, that the notion ofcontagionin many diseases is "far from being natural and obvious to the mind;" for, since the time that contagious properties have been generally allowed to belong to certain diseases, there has been a strong disposition to consider this as the most natural and obvious mode of explaining the spreading of other diseases. A person sees evidence of the transmission,mediateas well asimmediate, of small-pox, from one person to another; and, in other diseases, the origin of which may be involved in obscurity, he is greatly prone to assign a similar cause which may seem to reconcile things so satisfactorily to his mind. Indeed there seems, in many parts of the world, a degree ofpopularityas to quarantine regulations, which is well understood and turned to proper account by the initiated in the mysteries of that department:—for what more common than the expression—"we cannot be too careful in our attempts tokeep outsuch or such a disease?" For my part, I admit that I can more easily comprehend the propagation of certain epidemics by contagion, than I can by any other means,when unaccompanied by sensible atmospheric changes; and if I reject contagion in cholera, it is because whatever we have in the shape of fair evidence, is quite conclusive as to the non-existence of any such principle. Indeed abundance of evidence now lies before the public, from various sources, in proof of the saying of Fontenelle being fully applicable to the question of cholera—"When a thing is accounted for in two ways, the truth is usually on the side most opposed toappearances." How well mistaken opinions as to contagion in cholera are illustrated in a pamphlet which has just appeared from Dr. Zoubkoff of Moscow! This gentleman, it appears, has been a firm believer in contagion, until the experience afforded him during the prevalence of the disease in that city proved the contrary. He tells us (p. 10), that in the hospital (Yakimanka) he saw "to his great astonishment, that all the attendants, all the soldiers, handled the sick, supported their heads while they vomited, placed them in the bath, and buried the dead; always without precaution, and always without being attacked by cholera." He saw that even the breath of cholera patients was inhaled by others with impunity; he saw, that throughout the district of which he had charge, the disease did not spread through the crowded buildings, or in families where some had been attacked, and that exposure to exciting causesdeterminedthe attack in many instances. He saw all this, gives the public the benefit of the copious notes which he made of details as toPt_1[Pg 28]persons, places, &c., and now ridicules the idea of contagion in cholera. Grant to the advocates of contagion in cholera but all the data they require, and they will afterwards prove every disease which can be mentioned to be contagious. Hundreds of people, we will say, for instance, come daily from a sickly district to a healthy one, and yet no disease for some time appears; but at last an "inexplicable condition of the air," and "not appreciable by any of our senses" (admitted by Dr. Macmichael and others as liable to occur, butonly in aidof contagion), take place; cases begin to appear about a particular day, and nothing is now more easy than to make out details of arrivals, there being a wide field for selection; and even how individuals had spoken to persons subsequently attacked—had stopped at their doors—had passed their houses, &c.[8]Causation is at once connected with antecedence, at least for a time, by the people at large, who see their government putting on cordons and quarantines, and the most vague public rumour becomes an assumed fact. We even find, as may be seen in the quotation given from Dr. Walker's report, that contagionists are driven to the "somehow or other" mode of the introduction of cholera by individuals; so that it may be deplored, with respect to this disease, in the words of Bacon, that "men of learning are too frequently led, from ignorance or credulity, to avail themselves of mere rumours or whispers of experience as confirmation, and sometimes as the very ground-work, of their philosophy, ascribing to them the same authority as if they rested upon legitimate testimony. Like to a government which should regulate its measures, not by official information of its accredited ambassadors, but by the gossipings of newsmongers in the streets. Such, in truth, is the manner in which the interests of philosophy, as far as experience is concerned, have hitherto been administered. Nothing is to be found which has been duly investigated,—nothing which has been verified by a careful examination of proof."
[8]Since the above was written it has been very clearly shewn how easily proofs ofthis kindmay be furnished to all disposed to receive them. We perceive that a disease officially announced asthe truecholera, has existed for nearly a month past at Sunderland, and that among the thousands of people who left it within that time, nothing could be more easy, had the disease appeared epidemically in other parts of England, than to point out theparticular individualwho had "brought it" in some way or other; and this is the manner in which all the fables about the propagation of cholera from one district to another have gained credence.

In their efforts to make out their case, there would seem to be no end to the contradictions and inconsistencies into which the advocates of contagion in cholera are led. At one moment we are required to believe that the disease may be transmitted through the medium of an unpurified letter, over seas and continents, to individuals residing in countries widely differing in climate, while, in the next, we are told—regarding the numberless instances of persons of all habits who remain unattacked though in close contact with the diseased—that the constitution of the atmosphere necessary for the germination of the contagion is not present; andPt_1[Pg 29]this, although we see the disease attacking all indiscriminately, those who are not near the sick as well as those who are at a very short distance, as on the opposite side of a ravine, of a rivulet, of a barrack, or even of a road. They assume that wherever the disease appears,threecauses must be in operation—contagion—peculiar states of atmosphere (heat now clearly proved notessential, as at one time believed)—and susceptibility in the habit of the individual. However unphilosophical it is held to be to multiply causes, the advocates of contagion are not likely to reduce the number, as this would at once cramp them in their pleadings before a court where sophistry is not always quickly detected. Those who see irresistible motives for dismissing all idea of contagion, look, on the contrary, for the production of cholera, to sources, admitted from remote times to have a powerful influence on our systems, though invisible—though not to be detected by the ingenuity of man, and though proved to exist only by their effects.
Many who do not believe that cholera can be propagated by contagion under ordinary circumstances, have still a strong impression that by crowding patients together, as in hospitals or in a ship, the disease may acquire contagious properties. Now we find that when theexperimentum crucisof extensive experience is contrasted with the feasibility of this, cholera, like ague, has not been rendered one bit more contagious by crowding patients together than it has been shown to be under other circumstances. We do not require to be told that placing many persons together in ill-ventilated places, whether they labour under ague, or catarrh, or rheumatism, or cholera, as well as where no disease at all exists among them, as in the Calcutta black-hole affair, and other instances, which might be quoted,fever, of a malignant form, is likely to be the consequence, but assuredly not ague, or catarrh, or rheumatism, or cholera. On this point we are furnished with details by Dr. Zoubkoff, of Moscow, in addition to the many previously on record. It may be here mentioned that, on a point which I have already referred to, this gentleman says (p. 43), "I shall merely observe that at Moscow, where the police are remarked for their activity, they cannot yet ascertain who was the first individual attacked with cholera. It was believed at one time that the disease first showed itself on the 17th of September; afterwards the 15th was fixed upon, and at last persons went so far back as August and July." As this gentlemanhad beena contagionist, occupied a very responsible situation during the Moscow epidemic, and quotes time and place in support of his assertions, I consider his memoir more worthy of translation than fifty of your Keraudrens.
Respecting those mysterious visitations which from time to time afflict mankind, it may be stated that we have a remarkable instance in the "dandy" or "dangy" disease of the West India Islands, which, of late years, has attracted the notice of the profession as being quite a new malady, though nobody, as far as I am aware of, has ever stated it to have been an imported one. We find also that within the last three years a disease, quite novel in its characters, has been very prevalent in the neighbourhood of Paris. It has proved fatal in many instances, and thePt_1[Pg 30]physicians, unable to assign it a place under the head of previously-described disease, have been obliged to invent the term "Acrodynia" for it. I am not aware that even M. Pariset, the medical chief of quarantine in France, ever supposed this disease to have beenimported, and to this hour the cause of its appearance remains in as much obscurity among the Savans of Paris, as that of the epidemic cholera.
Considering all the evidence on the subject of cholera in India, in Russia, Prussia, and Austria, one cannot help feeling greatly astonished on perceiving that Dr. Macmichael (p. 31 of his pamphlet) insinuates that the spreading of the disease in Europe has been owing to the views of the subject taken by the medical men of India.
In turning now more particularly to the work, or rather compilation, of Dr. Bisset Hawkins, let us see whether we cannot discover among what he terms "marks of haste" in getting it up for "the curiosity of the public" (curiosity, Dr. Hawkins!), some omissions of a very important nature on the subject of a disease respecting which, we presume, he wished to enlighten the public. And first, glancing back to cholera in the Mauritius, Dr. Hawkins might, had he not been so pressed for time, have referred to the appearance of cholera in 1829, at Grandport in that island; when, as duly and officially ascertained, it could not be a question of importation by any ship whatever. The facility with which he supplies us with "facts,"—thefalse factsreprobated by Bacon, and said by Cullen to produce more mischief in our profession than false theories—is quite surprising; he tells us, point blank (p. 31), speaking of India, that "when cholera is once established in a marching regiment, it continues its course in spite of change of position, food, or other circumstances!" Never did a medical man make an assertion more unpardonable, especially if he applies the termmarching regimentas it is usually applied. Dr. Hawkins leads us to suppose that he has examined the India reports on cholera. What then are we to think when we find in that for Bengal the following most interesting and conclusive statements ever placed on record? Respecting the Grand Army under the Marquis of Hastings, consisting of 11,500 fighting men, and encamped in November 1817 on the banks of the Sinde, the official report states that the disease "as it were in an instant gained fresh vigour, and at once burst forth with irresistible violence in every direction. Unsubjected to the laws of contact, and proximity of situation, which had been observed to mark and retard the course of other pestilences, it surpassed the plague in the width of its range, and outstripped the most fatal diseases hitherto known, in the destructive rapidity of its progress. Previously to the 14th it had overspread every part of the camp, sparing neither sex nor age, in the undistinguishing virulence of its attacks."—"From the 14th to the 20th or 22d, the mortality had become so general as to depress the stoutest spirits. The sick were already so numerous, and still pouring in so quickly from every quarter, that the medical men, although night and day at their posts, were no longer able to administer to their necessities. The whole camp then put on the appearance of a hospital. The noise and bustle almost inseparable from the intercourse of large bodies of people hadPt_1[Pg 31]nearly subsided. Nothing was to be seen but individuals anxiously hurrying from one division of a camp to another, to inquire after the fate of their dead or dying companions, and melancholy groups of natives bearing the biers of their departed relatives to the river. At length even this consolation was denied to them, for the mortality latterly became so great that there was neither time nor hands to carry off the bodies, which were then thrown into the neighbouring ravines, or hastily committed to the earth on the spots on which they had expired." Let us now inquire how this appalling mortality was arrested;—the report goes on to inform us:—"It was clear that such a frightful state of things could not last long, and that unless some immediate check were given to the disorder, it must soon depopulate the camp. It was therefore wisely determined by the Commander-in-chiefto move in search of a healthier soil and of purer air," which they found when they "crossed the clear stream of the Bitwah, and upon its high and dry banks at Erich soon got rid of the pestilence, and met with returning health." Now just fancy epidemic cholera a disease transmissible by "susceptible articles," and what an inexhaustible stock must this large army, with its thousands of followers, have long carried about with them; but, instead of this, they were soon in a condition to take the field. Against the above historical fact men of ingenuity may advance what they please. There is no doubt that, in the above instance, severe cases of cholera occurredduring the move, the poison taken into the system on the inauspicious spot, not having produced its effects at once; it is needless to point out what occurs in this respect in remittent and intermittent fevers. The India reports furnish further evidence of mere removal producing health, where cholera had previously existed. Mr. Bell, a gentleman who had served in India, and who has lately written upon the disease,[9]informs us (p. 84), that "removing a camp a few miles, has frequently put an entire and immediate stop to the occurrence of new cases; and when the disease prevailed destructively in a village, the natives often got rid of it by deserting their houses for a time, though in doing so they necessarily exposed themselves to many discomforts, which,cæteris paribus, we should be inclined to consider exciting causes of an infectious or contagious epidemic." We even find that troops have, as it may be said,out-marchedthe disease, or rather the cause of the disease; that is, moved with rapidity over an extensive surface where the atmosphere was impure, and thereby escaped—on the principle that travellers are in the habit of passing as quickly as they can across the pontine marshes. Mr. Bell says, "In July, 1819, I marched from Madras in medical charge of a large party of young officers who had just arrived in India, and who were on their way to join regiments in the interior of the country. There was also a detachment of Sepoys, and the usual number of attendants and camp-followers of such a party in India. The cholera prevailed at Madras when we left it. UntilPt_1[Pg 32]the 5th day's march (fifty miles from Madras) no cases of the disease occurred. On that day several of the party were attacked on the line of march; and, during the next three stages, we continued to have additional cases. Cholera prevailed in the countries through which we were passing. In consultation with the commanding officer of the detachment, it was determined that we shouldleave the disease behind us; and as we were informed that the country beyond the Ghauts was free from it, we marched, without a halt, until we reached the high table land of Mysore. The consequence was, that we left the disease at Vellore eighty-seven miles from Madras, and we had none of it until we had marched seventy miles further (seven stages), when we again found it at one of our appointed places of encampment; but our camp was, in consequence, pushed on a few miles, and only one case, a fatal one, occurred in the detachment; the man was attacked on the line of march. We again left the disease, and were free from it during the next 115 miles of travelling; we then had it during three stages, and found many villages deserted. We once more left it, and reached our journey's end, 260 miles further, without again meeting it. Thus, in a journey of 560 miles, this detachment was exposed to, and left the disease behind it, four different times; and on none of those occasions did a single case occur beyond the tainted spots." What a lesson for Dr. Hawkins! Butfor whomcould Dr. Hawkins have written hiscuriousbook? Hear Mr. Bell in respect to the common error of the disease following high roads and navigable rivers only:—"I have known the disease to prevail for several weeks at a village in the Southern Mahratta country, within a few miles of the principal station of the district, and then leave that division of the country entirely; or, perhaps, cases would occur at some distant point. In travelling on circuit with the Judge of that district, I have found the disease prevailing destructively in a small and secluded village, while no cases were reported from any other part of the district." What is further stated by Mr. Bell will tend to explain why so much delusion has existed with regard to the progress of the disease being remarkably in the direction of lines of commerce, or great intercourse:—"When travelling on circuit, I have found the disease prevailing in a districtbefore any report had been made of the fact, notwithstanding the most positive orders on the subject; and I am persuaded, that were any of the instances adduced in support of the statement under consideration strictly inquired into, it would be found that the usual apathy of the natives of India had prevented their noticing the existence of the disease until the fact was brought prominently forward by the presence of Europeans. It should also be brought to mind, that cholera asphyxia is not a new disease to these natives, but seems to be, in many places, almost endemical, whilst it is well known that strangers, in such circumstances, become more obnoxious to the disease than the inhabitants of the country. Moreover, travellers have superadded to the remote cause of the disease, fatigue and road discomforts, which are not trifling in a country where there are neither inns nor carriages." (p. 89.) Cholera only attacks a certain proportion of a population, and is it wonderful that we should hear more of epidemic on high roads, where the population is greatest? HighPt_1[Pg 33]roads too are often along the course of rivers; and is there not some reason for believing, that there is often along the course of rivers, whether navigable or not, certain conditions of the atmosphere unfavourable to health? When Dr. Hawkins stated, as we find at p. 131 he has done, that where the inhabitants of certain hilly ranges in India escaped the disease, "these have been said to have interdicted all intercourse with the people below," he should have quoted some respectable authority, for otherwise, should we unhappily be visited by this disease, the people of our plains may one day wage an unjust war against the sturdy Highlanders or Welsh mountaineers.[10]Little do the discussers of politics dream of the high interest of this part of the cholera question, and little can they conceive the unnecessary afflictions which the doctrine of the contagionists are calculated to bring on the nation. Let no part of the public suppose for a moment that this is a question concerning medical men more than it does them;allareverydeeply concerned, the heads of families more especially so.
