Of the 12 fatal cases which occurred here, eight of the subjects were in a state of complete collapse—cold livid and pulseless—on admission; in another collapse was nearly complete, and death speedily followed in all, without the slightest sign of re-action. In one of the remaining three cases, there were slight and transient periods of re-action, alternations of promise and discouragement for fifty hours, when fatal sinking came on. In the other two, the first danger was past, but severe re-actionary fever followed. In one there was restoration of the biliary secretion; in the other, during the last eighteen hours the subject had the complete appearance of a patient in West Indian fever, discharging largely from the stomach, and more sparingly from the bowels, a fluid exactly resembling _black vomit_. In the cases, which terminated in recovery, the impression was severe, though not equally so; and in each the symptoms, as already stated, were considered clearly characteristic of the prevailing epidemic. In some of them no hope was entertained for a time; especially in two cases, where there was in excess, lividity of surface, cold sweats, corrugated skin, bent fingers and toes, and failure of pulse. In considering the probability of recovery from cholera, there is reason to think that the manner of attack should be taken into account, jointly with the severity of subsequent symptoms. From what was observed here, it appeared that when there had been precedent diarrhœa, or when there had been—though sudden—a gradual progress to the collapsed state, there was a much better chance for the patient than when the disease, in overwhelming force, fell upon him at once. When, soon after eating a hearty meal, in perfect health, the subject is obliged to be relieved from duty in the ranks, or on deck, becoming in an instant faint and giddy, with a rush of fluid from the stomach and bowels, shrinking of features, fluttering pulse, coldness of surface tongue and breath—struck down, as it were, by electricity—to which soon followed the up-turned ecchymosed eye and whispering voice—when the disease thus sets in, it is doubtful whether art has any power to arrest, or materially modify its fatal career. Such, at least, is the impression from what was observed here; and such, without questioning what has been alleged to have been done by others, or disparaging the means they employed, it is apprehended will be the conclusion of most observers elsewhere. The practice pursued in Haslar Hospital is submitted to the profession, not because it had any very eminent success, nor on account of its including new remedies, but because the proportion of recoveries was at least fully as large as that which has followed other modes of treatment; because there was some novelty in the combination of the means employed; and because it is thought that any contribution to the therapeutics of cholera will be acceptable.
