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 to 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 us _what does_ come 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 way _immediately precedes_ the 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
