Disinfection and Individual Prophylaxis against Infectious Diseases. By George M. Sternberg, M. D. Concord, N. H. Pp. 40.
This essay is published by the American Public Health Association as one of the four papers on as many subjects of public sanitation, for which the prizes offered by Mr. Henry Lomb, of Rochester, New York, were awarded. The author, who has long been pursuing a scientific and practical study of all that relates to microbic infections, has in it explained the nature and office of disinfection and disinfectants, with the value and effect of the different substances in general use, and directions for application and for individual prophylaxis against the infectious diseases which man is liable to contract. The essay is designed for general use, and is, therefore, free from technicalities, and is for sale at "a price covering the cost," which we do not find specified.
The Relation of Hospitals to Medical Education. By Charles Francis Withington, M. D. Boston: Cupples, Upham I &Co. Pp.47.
Dr. Withington starts out with the I proposition that measures not distinctly contemplated by the founder of a trust may, in the course of time or by changes in conditions and circumstances, become necessary to the truest fulfillment of the spirit of the trust. Among such measures is the use of hospitals as aids in medical education. Two objections may be brought against this view: one, that while the advancement of medical education is for the advantage of all men, there is no special obligation resting upon hospitals more than upon the general medical profession to contribute to it; and that the use of a hospital for such purposes may be in conflict with the comfort and wellbeing of the persons under treatment. These objections are answered: First, it is held that, since hospitals possess certain facilities for the advancement of medical science, having relation to important elements in medical education that are not enjoyed elsewhere, they are under a peculiar obligation to second this work; next, the possible conflict between the interests of medical science and those of the individual patient is considered, and the latter's indefeasible rights are defined; and in a third section the factors increasing the educational value of hospitals are discussed.
The Journal of Physiology. Edited by Michael Foster, M. D. Vol. VII. Nos. 3 and 4. Cambridge, England. Pp. 164. Price, $5 a volume.
Dr. Foster has the co-operation in conducting the "Journal of Physiology," in England, of Professor W. Rutherford, of Edinburgh, and Professor J. Burdon-Sanderson, of Oxford; and in the United States, of Professor H. P. Bowditch, of Boston; Professor H. Newell Martin, of Baltimore; and Professor H. C. Wood, of Philadelphia. The numbers appear, not at rigidly fixed times, but at varying intervals, which are determined by the supply of material. The two numbers now under notice contain fifteen articles descriptive of original physiological research, by W. M. Bayliss and J. R. Bradford, J. W. Barrett, C. A. Mac-Munn, M. Greenwood, S. Pallitzer, Sydney Ringer, F. W. Ellis, Francis Warner, W. D. Haliburton, and R. Norris Wolfenden. The papers of most general interest are, perhaps, those of S. Pallitzer on "Curare," and R. Norris Wolfenden on "The Nature and Action of the Venoms of the Indian Cobra and the Indian Viper."
