exempli fying on a large scale the lower protein intake which has 

 been advocated by Chittenden as the outcome of his experimental 

 researches. On the ground of his newer evidence of the inferi- 

 ority of the Indian races or tribes existing on the lower dietaries 

 McCay believes that the views of Chittenden are untenable; and 

 he takes occasion to criticize some of the deductions which Chitten- 

 den has drawn from his own researches, as well as to point out 

 features in the American investigations which seem to speak 

 against the newer contentions. The problem is one that calls 

 for careful physiological analysis and must be emancipated from 

 the domination of mere opinion or prejudices in matters of 

 nutrition. Hitherto there has been too much of the sentimental 

 and too little of the scientific in the advocacy of schemes of diet. 

 The present book is one of the newer contributions which speaks 

 for a more rational attitude towards the problems at issue. The 

 final word is, however, not yet spoken. l. b. m. 



9. Principles of Hygiene ; by D. H. Bergey, M.D. Fourth 

 edition thoroughly revised. Pp. 529, illustrated. Philadelphia 

 and London, 1912 (W. B. Saunders Company). — Few individuals 

 can be expected to-da} T to master the many diverse fields of science 

 which are encompassed in the modern discipline of L^giene. This 

 may serve to explain why there so few satisfactory text-books on 

 the subject and to excuse the obvious inequalities of the various 

 chapters of the volume by Bergey. To present the subjects of heat- 

 ing and sewage-disposal ; soils and diet ; immunity and water-sup- 

 plies ; clothing and naval hygiene ; habitations and exercise, in the 

 limits of a book of ordinary size and in an effective, authoritative 

 and up-to-date fashion is no mean accomplishment. This volume 

 excels in those subdivisions which relate more directly to the 

 author's personal experience. It affords a convenient survey over 

 the entire field ; while for some of the divisions the critical reader 

 will doubtless find it of advantage to consult special monographs. 

 The range of topics is a very broad one; but some of the chapters 

 could be greatly improved by a more radical revision. This is 

 conspicuously true, for example, of the section on food and diet 

 where one reads of mineral waters as " regulators of energy" and 

 that fats serve "as nutrition to the nervous system." l. b. m. 



10. An Essay on Hasheesh; by Victor Robinson. Medical- 

 Review of Reviews. Pp.83. New York, 1912.— A semi-serious 

 historical account of the distribution of Cannabis indica, its use 

 in medicine and its employment in the production of hasheesh 

 debauches. The account is interspersed with enlivening bits of 

 wit, and includes a graphic description of the exhilarating effects 

 of this subtle drug observed after its administration to men — 

 among them the author. It is doubtful whether the publication 

 of such questionable experiments in drugdom serves any com- 

 mendable purpose. l. b. m.
