1916] ANIMAL PRODUCTION. 371 



" A study of the new controls, together with those reported in the literature 

 since . . . [the] last publication [E. S. R., 34, p. 68], supports the views pre- 

 viously expressed. There is no reason to change the statement made in . . . 

 [the] previous paper, that if a given subject's basal metabolism is more than 10 

 per cent from the average, it may be regarded as abnormal, but can not be 

 proved abnormal unless the departure from the average is at least 15 per cent. 

 The average basal metabolism of normal men is 34.7 calories per square meter 

 per hour as determined by Meeh's formula. On account of the average plus 

 error of about 15 per cent in Meeh's formula the average figure is 39.7 calories, 

 or in round numbers 40 calories, when the more exact ' linear formula ' or the 

 new ' height-weight formula ' is used to determine surface area. 



" The average metabolism of fat and thin subjects is the same according to 

 surface area when the surface area is correctly measured. The metabolism of 

 women averages 37 calories, or 6.S per cent lower than that of men. A group 

 of men and women between the ages of 40 and 50 gave figures 4.3 per cent 

 below, and a group 50 to 60 years old 11.3 per cent below the average for the 

 larger group between the ages of 20 and 50. 



" Under the atmospheric conditions of the calorimeter experiments the aver- 

 age water elimination by normal men through skin and lungs is 28.4 gm. 

 an hour. About 24 per cent of the heat produced is dissipated in the vaporiza- 

 tion of water. 



" The figures for the specific dynamic action of protein and glucose previously 

 obtained are confirmed. A table of normal standards is given." 



XIV. MetaboHsm in exophthalmic goiter, E. F. Dubois (pp. 915-964). — By 

 means of the respiration calorimeter, 37 observations were made on 11 patients 

 suffering from exophthalmic goiter. 



XV. The basnl metabolism in pernicious anemia, A. L. Meyer and E. F. Du- 

 bois (pp. 965-979). — A report of calorimetric observations of basal metabolism 

 in six cases of anemia. 



XVI. The basal metabolism of patients tmth cardiac and renal disease, F. W. 

 Peabody, A. L. Meyer, and E. F. Dubois (pp. 980-1009). — Clinical observations 

 and calorimeter experiments are reported. 



XVII. Metabolism and treatment in diabetes, F. M. Allen and E. F. Dubois 

 (pp. 1010-1059). — The data of clinical observations and respiration calorimeter 

 experiments during the treatment of six cases of diabetes are reported in 

 detail. 



The basal energy requirement of man, E. F. Dubois (Jour. Wash. Acad. Sci., 

 6 (1916), No. 11, pp. 347-357, fig. 1). — In this lecture the author considers the 

 definition of the term basal energy requirement, the manner in which metabo- 

 lism is studied, and the factors by which it is influenced in health and disease. 

 Although muscular work affects metabolism to a greater extent than all other 

 factors combined, attention is called to the very important part that diet plays 

 in such diseases as typhoid fever, exophthalmic goiter, and diabetes. 



ANIMAL PRODUCTION. 



Vigor and heredity, J. L. Bonhote {London: West, Newman & Co., 1915, 

 pp. XII +263, pis. 11, figs. 4). — This book treats of the inadequacy of present 

 theories of heredity, prepotency, inbreeding, coloration as an index of vigor, 

 and other related subjects. 



The formation of protein in the animal body from the nonprotein sub- 

 stances, A. Stutzer {Fuhling's Landw. Zty., 64 {1915), No. 11-12, pp. 281-
