Hygienic cookery, Henrietta W. Calvin {Industrialist, Agr. Ed. Ser.. I 

 {1907), y<>. 3. pp. 33-o8). — Food and its preparation are discussed in this 

 article, wbich is designed to meet the needs of rural schools and is included 

 in the agricultural educational series, issued in connection with the college

Metabolism experiments with 32 children 3 to 6 years old, E. Muller 

 {Biochem. Ztschr., 5 (1907). No. 2-.',, pp. lJi3-303, tables 18).— lu the metabolism 

 experiments rei)orted special attention was paid to determinations of energy 

 value. According to the author's conclusions, children 3 to 6 years old on an 

 average required 87 calories per day or 16.7 calories per square decimeter of 

 surface area. The average coefficient of digestibility of fat was found to be 94.4 

 per cent and the amount resorbed per kilogram of body weight 3.26 gm. as 

 compared with a consumption of 3.45 gm. 



In the author's opinion, the results do not furnish final data regai'ding iiitro-' 

 gen values, as the possibility of diminishing nitrogen when nitrogen-free ma- 

 terial is present in abundance was not studied. The food consumed by the 

 children studied furnished on an average 0.55 gm. nitrogen per day per kilogram 

 of body weight, of which 0.04 gm. was retained.
