" The results presented in this report are to be considered simply as indi- 

 cating the normal metabolism of healthy young men at rest and under several 

 conditions of muscular activity. The variations from the normal exhibited 

 by the individual can be seen by an examination of the tables. The attempt 

 is made to point out the cause of the variations in so far as possible, but with 

 so complex a process as the energy transformation and katabolism in the body, 

 it is clearly futile to attempt to predict with r?;reat accuracy either the katab- 

 olism or the energy transformations of a given individual. Approximate values 

 that may prove of practical use can be obtained by means of some of the 

 factors outlined in this report. With more accurate and improved calorimeters, 

 there should be in the course of a few years the addition of many factors, at 

 present entirely unknown," 



Old age deferred, A, Lorand (Philadelphia, 1910, pp. XI+458). — Factors 

 which affect longevity are discussed. Chapters are included on such topics as 

 the hygiene of the intestine, rational clothing, the production and destruction 

 or elimination of toxic bodies, the relation of different foods and dietary habits 

 to the question of long life, and related matters. 



Practical dietetics with reference to diet in disease, Axida F, Pattee 

 (Mount Vernon, N. Y., 1910, 6. ed., pp. XXX+527, figs. 9).— A considerable 

 amount of new matter has been included in this revised edition, particularly 

 data regarding the fuel value of the foods and diets under consideration. 



The author states that Mary D. Swartz Rose has assisted in the revision, 



Pattee's handbag' diet book, Alida F. Pattee (Mount Vernon, N. Y., 1911, 

 pp. VII+186, figs. 2). — The material, reprinted from the author's Practical 

 Dietetics with Reference to Diet in Disease (see above), corhsists chiefly of 

 recipes and data regarding the preparation of invalid dishes and diets. It is 

 designed especially for the use of nurses and it has been the author's purpose 

 to present the material in a small volume which could be carried in a nurse's 

 handbag. 



The use of rice bran in the prevention and cure of beriberi, L. Br^audat 

 and Denier (Ann. Inst. Pasteur, 25 (1911), No. 2, pp. 167-189, figs. 5). — This 

 discussion includes statistical, experimental, and analytical data. The general 

 conclusion drawn is that 40 gm. of rice bran per day exercised preventive and 

 curative action. 



An extended bibliography is appended. 



ANIMAL PRODTJCTION. 



The genotype conception of heredity, W. Johannsen (Amer. Nat., ^5 

 (1911). No. 531, pp. 129-159, figs. 6). — The transmission of personal qualities is 

 regarded as a naive and now antiquated conception of heredity; likewise, the 

 biometrical definition of heredity as the correlation between parent and off-
