often impossible to properly nourish young animals exclusively on one kind of 

 vegetable protein. . . . This has been attributed to a want of certain con- 

 stituents in vegetable proteins." 



Budget of twenty-two workingmen's families in Munich, E. Conrad (Ein- 

 selsvhr. ^tatis. Amt. Milnchcn, lii09, Xo. 8, pp. 80; ahs. in Hyg. Rundschau, 19 

 (1909), No. 18, p. 1087). — Statistics regarding wages, total expenditure for 

 food, expenditure for individual food materials, and similar data are included 

 in this report. 



Parsimony in nutrition, J. Crichton-Browne (London and New York, 1909, 

 pp. VI +111 ) . — In this volume the author gives reasons for his belief in a gen- 

 erous rather than a low proteid diet, drawing his evidence from personal ex- 

 perience, considerations of public health, study of the animal functions, under- 

 nutrition of school children and of the poor, and the experience of mankind in 

 general. 



This volume is an expansion and revison of the author's presidential address 

 to the section of preventive medicine at the meeting of the Royal Institute of 

 Public Health, July, 1908 (E. S. R., 20, p. 769). 



Appetite in relation to experimental physiology and clinical pathology, 

 W. Sternberg (ZcntU. Physiol., 23 (1909), No. 10, pp. 306-32',) .—In this ex- 

 tended summary and discussion of data the author emphasizes the need of 

 considering appetite and lack of appetite in relation to the preparation of food 

 for normal individuals, in invalid dietetics, and related questions. 



The influence of sodium chlorid on the digestion and absorption of proteid 

 materials, C. Padeki (Arch. Farmacol. Bper. e Sci. Aff., 8 (1909), No. 6, pp. 

 2.',9-261; aJ)s. in Cheni. ZentN., 1909, II, No. 10, p. 8J/3).— From experiments 

 with animals and in vitro the author concludes that the presence of sodium 

 chlorid facilitates the cleavage of amino acids from peptones. Large quantities 

 of sodium chlorid hinder the process. 



The output of organic phosphorus in urine, G. C. Mathison (Bio-Chem. 

 Jour., Jf (1909), No. 5-7, pp. 27 ',-279). — Organic phosphorus compounds, the 

 author concludes, are normally present in urine, contrary statements being due 

 to the employment of incorrect methods of analysis. In young adults, on an 

 ordinary diet, the organic phosphorous was usually found to be more than 0.1 

 gm. per day. Occasionally it fell below this, while in one case it reached 0.3 gm. 



" The percentage of the total P2O6 present in organic combination varies 

 considerably from day to day. In the cases examined it averaged 6 per cent of 

 the total. 



" The addition of a large quantity of organic phosphorus in the form of 

 glycerophosphoric acid to the diet had no distinct effect on the output of organic 

 P2O5, while it increased the total P2O5 output. Glycerophosphoric acid was 

 not broken down by gastric or pancreatic digestion in vitro, so it was probably 

 absorbed unchanged. 



" In the observations made, vigorous exercise was not followed by increased 

 output of organic P2O5. 



" The N : P2O5 ratio was fairly constant in any one individual on a fairly 

 regular diet. It differed greatly in different individuals, and also in the same 

 individual when the diet was irregular." 



Effects of chocolate and coffee on uric acid and purins, P. Fauvel (Compt. 

 Rend. Acad. Set. [Paris], 1J,8 (1909), No. 23, w>. 15J|l-loJ,J^).—^\\th. persons on 

 a vegetarian diet chocolate and coffee increased the output of purin bases and 

 diminished uric acid excretion, the diminution being apparently not due to 

 retention in the organism. The excretion of uric acid quickly became constant 

 and remained at the minimum for purins of endogenous origin in the case of the 

 long continued use of chocolate and coffee on a diet otherwise free from purins.
