"Cholera. ravaging here at long, intervals. is not nature's only retribution for our neglect in such matters as are in question. Typhoid fever and much_ endemic diarrhea arc, as 1 have often reuorted, incessant witnesses to the snow deleteriods influence; typhoid fever, which annually kills some 15,000 to 20,c00 of our population, and diar-, Om, which kills many thousands besides. The mere quantity of this wasted life is hor rible to contemplate, and the mode in which the waste is caused is surely nothing less than shameful. It is to be hoped that, as the education of the country advances, this sort of thing will come to an end; that so much preventable death will not always be accepted as a fate; that, for a population to he thus poisoned by its own excrement, will some day be deemed ignominious and intolerable." III conclusion we may that Mr. Simon's ninth report for 1866 (published in 1867) is one of the most valuable contributions to the literature of cholera that has ever been presented to the profession. The history of this disease in England in 1860 is first given. This is followed by a series of scientific investigations on the following points: 1. Examination of the degrees of success attained by different methods of treatment of cholera at Gny's, St. Bartholomew's, the London, and St. Thomas's hospitals. 2. Study of the successive Moment changes under zone by the body in cholera. 3. Similar study, chiefly microscopical, of the successive anatomical changes of the affected body. 4. Col
lection of facts as to the non-coincidence of local epidemics of cholera with such condi tions of the local ground-water as are indicated by a foul state of the surface-wells. The results of these startles are given in the appendix. Unfortunately, the practical result of these inquiries is, that ill cases of developed cholera our utmost power is but perhaps some very little ab;lity of palliation, and in the treatment of incipient cholera competent physicians are not agreed that even here their art has much efficiency." In contrast with the powerlessness of curative medicine, the power of preventing it is about the happidst possession of science. The evidence of Dr. Buchanan and others clearly shows that cholera mac be prevented by due intention to sanitary works, which provide for the prompt and complete removal of fecal impurities, and the plentiful supply of water which cannot have been exposed to this form of contamination. In addition to the works quoted in this article, we may refer those of our readers who wish to study this subject more fully, to the French treatises on hygiene by Becquerel, Levy. Tardieu, Yernois, and others. There is, however, no work on the subject in any language equal to that of Dr. Parkes. from which we should not have ventured to borrow so freely if we had not had the author's kind permission.
