Grape, fruit, and berry wines. — Pastes and other products, F. von Canstein 

 iJahrl). Deut. Laiulw. GcscIL, 25 {1910), No. 3. pp. 612-616).— Wines, macaroni, 

 and other products were examined. 



The nuclein content of foods, particularly those of East Indian origin, 

 G. J. Jebbink {Over het mideiriengehaJte van menschelyk voedsel en vooral 

 van IndAsche Versnaperingcn. Diss., 1910; aJ)s. in Zentbl. Gesani. Physiol, u. 

 Path. Stotfivechsels, n. set:, 5 {1910), No. 21, p. 829 ) .—Analyses of 60 foods 

 and condiments are reported, the work being undertaken with special reference 

 to the relation of organic phosphorus to beriberi. 



Notes on the diet of professional athletes, T. Siebert {Vmschau, U, 

 {1910), No. 49, pp. 975, 976, fig. Jf).— Tbe author records data concerning the 

 food habits of several professional athletes. In his observations the quantity 

 and character of the food varied very widely and he concludes that each man 

 must select the food which suits his individual needs. 



The feeding of school children, Helene Simon {Die Hchulspeisung. Leip- 

 sic. 1909. pp. F///+ 93). —Pioneer work in the systematic feeding of school 

 children, the conditions which must be met, and other questions are discussed 

 with reference to work in Germany and other countries. 



The food of school children in Mannheim, Helene Simon {tioz. Praxis, 20 

 {1910), No. 9, pp. 280, 2S_?).— Statistical and other data are given regarding the 

 feeding of school children under municipal auspices. 



Report of the penny lunch experiment in Boston, January 1 to June 30, 

 1910, Ellen H. Richards {Jour. Home Econ., 2 {1910), No. 6, pp. 6'iS-653).— 

 An account of the enterprise is given and suggestions made for future work. 



A day's metabolism, Clara C. Benson et al. {Jour. Home Econ., 2 {1910), 

 No. 6, p. 658). — The results are briefly reported of an experiment in which the 

 nitrogen balance was determined with a subject on a mixed diet. The urine 

 was collected at hour intervals. 



The day's diet supplied 11.5G gm. nitrogen and 9.74 gm. was found in the 

 urine and 1.38 gm. in the feces, which implies a gain of 0.44 gm. The total 

 phosphorus excretion for 24 hours was 0.7 gm. and the sodium chlorid excretion 

 7.2 gm. 



A comparison of the total nitrogen excretion of either kidney in normal 

 individuals during varying periods of time, T. B. Barringer, Jr., and B. S. 

 Barringer (A)«er. Jour. Physiol., 27 {1910), No. 1, pp. 119-121).— A. number of 

 observations of the quantities excreted by each kidney are recorded. In one 

 case the amounts were found to be equal. Six times they varied by less than 

 10 per cent and 4 times they varied from 10 to 20 per cent. 



"As regards the total nitrogen, in one case the quantities were equal. In 

 seven cases they varied by less than 1 gm. per liter. In two cases they varied 

 by between 1 and 2 gm. per liter. The nitrogen-urea plus ammonia-urea showed 

 in three cases a variation of less than 1 gm. per liter and in six cases a variation 

 of between 1 and 2 gm." 



The work of digestion in a carbohydrate diet in relation to the physical 

 influence of food, O. Mijller {Biochcm. Ztschr., 28 {1910), No. 5-6, pp. 427- 

 455). — Experiments were made with dogs and included studies of the respira- 

 tory quotient and related factors. 



According to the author, the results indicate that when starch was taken the 

 amount of energy liberated from the body was much greater than was the case 

 with sugar. The observation that small amounts of food involved less work of 

 the digestive organs than larger quantities in his opinion needs further study. 

 In general, he concludes that his results with large quantities of starch and 

 sugar show that on a starch diet 9.25 calories per 100 calories of digested mate- 

 rial were produced during 8 hours in excess of the value for a fasting animal,
