A hyg-ienic interpretation of the food supplied the United States Army 

 in the field as at present authorized, A. A. Woodhull (War Dept. [U. 8'.], 

 Off. Surg. Gen. Bui. 2, 1913, pp. 120-123) .—Thin article considers the food A'alue 

 of the various army rations. 



Food values and living on threepence a day, F. J. Cross (Reporter Proc. 

 Council [Charity Organ. Soc. London], 1913, pp. 1-10). — In this paper and the 

 discussion which follows information is given regarding the kind and cost of 

 food used by poor families in England and Scotland, and suggestions are made 

 for bettering the diet. 



Eng'lish cookery books to the year 1850, A. W. Oxford (London, Edin- 

 burgh, and New York. 1913, pp. 192; rev. in Brit. Med. Jour., 1913, No. 2733, 

 p. 1166). — A collection of titles of cookery books which appeared from 1500 to 

 1850, together with data gathered from them, including matter which bears on 

 domestic economy. See also a previous note (E. S. R., 22, p. 167). 



Traveling- kitchens, N. D. Walker (Jour. Roy Army Med. Corps, 20 

 (1913), No. 3, pp. 2Jf8-27Jf, figs. 12). — Descriptions are given of different sorts 

 of portable kitchen equipment for army use, including devices which employ the 

 fireless cooker principle. A bibliography is appended. 



An electrical oven, K. MoHs (Ztschr. Gesam. Getrcidcic. 5 (1913), No. 5, 

 pp. 152-15.5, figs. 2). — An electrical oven for bakers' use is described and some 

 data given regarding its efficiency. 



A temperature regulator, E. Esclangon (Compt. Rend. Acad. Sci. [Paris], 

 156 (1913), No. 22, pp. 1667-1670, figs. 3).— A temperature regulator for experi- 

 mental purposes is described by means of which the heating is increased or de- 

 creased by the disturbance of the center of gravity of the apparatus through 

 the movement of a column of mercury, due to expansion or contraction of a 

 body of vapor with which it is in contact. The regulator is especially useful 

 in bacteriological work. 



The effect of light on metabolism, L. Pincussohn (Berlin. Klin. Wchnschr., 

 50 (1913), No. 22, pp. 1008, 1009). — The results of preliminary experiments are 

 reported in which the metabolism was studied of a dog exposed to strong light. 



The mechanism of protein assimilation (Jour. Anier. Med. Assoc, 60 

 (1913), No. 20, p. 15.^6). — This is a brief summary of recent studies which ap- 

 parently show that the amino acids resulting from protein digestion are 

 absorbed from the blood by the tissues and held there by physical means in 

 amounts varying with the different tissues, being transformed chemically 

 later on. 



Since the retained amino acids disappeared much more rapidly from the liver 

 and kidneys than from the muscles and the other organs, this disappearance 

 being accompanied by an increase of urea in the blood, it is probable that the 

 entire task of removing the products of digestion from the blood stream when 

 the other tissues become saturated devolves on these two sets of organs.
