values from earlier work with flesli eaters being selected for the coruparisoii. 

 Comparisons of the dynamometer force, calculated as kilograms, gave prac- 

 tically the same results for vegetarians and flesh eaters, namely, 38 kg. for the 

 former and 37 kg. for the latter. Lung capacity and body size were studied 

 as well as some psychological measurements. 



The rational feeding of infants from birth to two years of age, H. Klose 

 (Rev. Soc. Sci. Hyg. Aliment., S {1906), Xo. 3, pi). S63-U2, dgms. 9).— The 

 author considers in some detail the problem of the rational feeding of infants, 

 and reports several observations on artificial feeding according to different for- 

 mulas. An extensive bibliography is appended. 



The rational feeding of infants from birth to two years, Michel and 

 Perret (Rev. tioc. Sci. Hyg. Aliment., 3 (1906), Xn. 3, pp. 209-363, dgms. 9).— 

 Noted from another source (E. S. R. 18, p. 959). 



How to nourish infants, Sosnows^a (Rev. Soc. Sci. Hyg. Aliment., 3 (1906), 

 No. 3, pp. 443--i-i9).— A brief consideration of the possibility and, in the author's 

 opinion, desirability of nourishing infants of 9 months and even younger on 

 vegetarian or fruitarian diet. 



Eggs in the diet of infanljs, W. J. Midelton (Brit. Med. Jour., 1907, No. 

 2422, p. 1302). — On the basis of experience, the author recommends eggs as a 

 substitute for mother's milk in infant feeding. For the first 2 days after birth 

 a mixture of egg white, water, and cane sugar is^used; afterwards egg yolk is 

 added in increasing amounts together with a little cod-liver <»il emulsion. 



The nourishment of youths of both sexes in the family and in educational 

 institutiohs, P. Legendre (Rev. Soc. Sci. Hyg. Aliment., 3 (1906), No. 3, pp. 

 .'i50-^68). — A discussion of the principles of alimentary hygiene as applicable 

 to the feeding of children from G to 16 years of age, with special reference to 

 methods of modifying the diet of a group or an institution to m^t the needs of 

 individuals. The article includes an account by L. Aman of the dietary regime 

 of a large •>rphaiuige as established in accordance with the principles discussed. 



The food of Belgian farmers and farm laborers, A. Lonay (Rev. Soc. Sci. 

 Hyg. Aliment., 3 (1906), No. 2, pp. 10-83). — Food customs of the agricultural 

 population in different districts of Belgium are described and many data 

 regarding the kinds and amounts of food eaten are summarized. 



The author believes that the facts warrant the statement that the 'agri- 

 cultural population of Belgium, though they are the food producers, do not 

 themselves have a diet which other laborers would envy. He calls attention 

 to the fact that existing conditions have been recognized by tlie Belgian minis- 

 ter of agriculture, and quotes largely from a circular which has been widely 

 distributed by the minister giving i)ractical directions for the improvement of 

 the diet. 



The investigations of the Institute Solvay on the food of Belgian laborers, 

 P. Heger, a. Slosse, and E. Waxweiler (Rev. Soc. Sci. Hyg. Aliment., 3 (1906), 

 No. 2, pp. 1-33). — In this extended investigation of sociological and other con- 

 ditions and their effect upon the diet of Belgian laborers, records kept in 1,250 

 families representing about (),000 persons were gathered. Of these, 1,065 were 

 sufiiciently detailed and accurate to include in the sununary and discussion. 



The results were classified in two ways, namely, according to the work, 

 whether moderate, severe, or very severe, and according to regions, wliether 

 urban, industrial districts, or rural communities, and the attempt was made 

 to discover the relation of these factors to diet. Tn nearly nine-tentlis of the 

 total number of families the daily quantity of protein was 105 gm. or less per 

 man per day and in over half it was less than 35 gm. The energy was not 

 far from 3,400 calories as a mean value.
