Petersburg, has just given to the public an account of his observations there during the epidemic, from which the following extracts are made:-- "As far as my practice is concerned both in the quarter allotted to me, and also in private houses in different parts of the town, I have no proof whatever that the disease is contagious. "The first patient I saw was upon the third day of the epidemic, and upon strict inquiry I could not trace the least connexion between the patient, or those who were about her person, with that part of the town where it first appeared--a distance of several versts. "As regards the attendants of the sick, in no one instance have I found them affected by the disease, though in many cases they paid the most assiduous attention, watched day and night by the beds of the afflicted, and administered to all their wants. "I knew four sisters watch anxiously over a fifth severely attacked with cholera, and yet receive no injury from their care. "In one case I attended a carpenter in a large room, where there were at least thirty men, who all slept on the floor among the shavings; and, though it was a severe and fatal case, no other instance occurred among his companions. "In private practice, among those in easy circumstances, I have known the wife attend the husband, the husband the wife, parents their children, children their parents, and in fatal cases, where, from long attendance and anxiety of mind, we might conceive the influence of predisposition to operate, in no instance have I found the disease communicated to the attendants."--p. 32, 33. "The present disease has borne throughout the character of an epidemic, and when the proofs advanced in proof of its contagion have been minutely examined, they have been generally found incorrect; whereas it is clear and open to every inquirer, that the cholera did not occur in many places which had the greatest intercourse with St. Petersburg at the height of the malady, and that it broke out in many others which have been subjected to the strictest quarantine."--p. 34.[16] [Footnote 16: It is remarkable enough that Aretaeus, who lived, according to some authors, in the first century, gives exactly the same reason which Dr. Lefevre does for the suppression of urine in cholera. So true it is, that that symptom, considered as one of the characteristics of the Indian cholera, was observed in ancient times.] Hear all this, Legislators! Boards of Health throughout the country, hear it! Then you will be able to judge how exceedingly frivolous the idle _opinions_ and _reports_ are which you have obtruded so industriously upon your notice.
