The bacillus carrier and the restaurant, A. I. Kendall (Amer. Jour. Pub. 

 Health, 6 {1916), No. 7, pp. 726-720).— This article considers the danger of the 

 contamination of food by tlie bacillus carrier, and describes the measures taken 

 to prevent such contamination in the restaurant of a department store when it 

 was possible that some of the cooks and waitresses had been exposed to typhoid 

 infection. The measures taken included thorough scrubbing of the hands before 

 starting work and after any absence from the restaurant during the day ; the 

 application of the Widal test ; and the examination of the urine and the feces. 



[Care of the baby], E. F. Ladd and Alma K. Johnson (North Dakota Sta. 

 Spec. Bui., 4 {1916), No. 5, pp. 97-132, figs. 8). — This contains information on 

 the care and feeding of children. 



The diet of children after infancy, J. H. M. Knox (Jour. Amer. Med. Assoc, 

 67 (1916), No. 6, pp. 432-435). — This paper calls attention to such data as are 

 available regarding the food requirements of young and growing children, and 

 gives diet lists suitable for a child from 12 to 18 months and a child from 2 to 4 

 years of age. The author emphasizes the importance of giving more considera- 

 tion to the diet of young children. 



The new emerg'ency ration [of the XJ. S. Army] (War Dept. [U. S.] Ann. 

 Rpts., 1915, I, pp. 271, 272). — A brief progress report of the work on the emer- 

 gency ration conducted by the Office of Home Economics of the U. S. Depart- 

 ment of Agriculture. 



Report by the departmental conimittee appointed to inquire into the ques- 

 tion of maintaining and if possible increasing the present production of 

 food in Scotland, E. Wason et al. (Edinburgh: Govt., 1915, pp. 16). — A num- 

 ber of recommendations are formulated. 



Minutes of evidence taken before the departmental committee appointed 

 to inquire into the question of maintaining and if possible increasing the 

 present production of food in Scotland (Edinburgh: Govt., 1915, pp. 166). — 

 This publication contains the minutes of the hearings and other evidence upon 

 which the above report was based. 



The normal gastric secretion, M. E. Rehfuss (Proc. Amer. Phil. Soc, 55 

 (1916), No. 6, pp. 461-470). — In this article the aiithor brings together a 

 great deal of information regarding the normal secretion of the gastric juice 

 which has been obtained in a number of experiments by himself and other in- 

 vestigators, notably Hawk, Bergeim, Fowler, Spencer, Clarke, and others. The 

 bulk of the material has been noted from other sources. 



The uric acid solvent power of normal urine, H. D Haskins (Jour. Biol. 

 Chem., 26 (1916), No. 1, pp. 205-215). — The experimental data here reported 

 may be summarized briefly as follows : 



" When shaken with uric acid for 20 minutes at 37° C. many urines that are 

 slightly acid and all that are neutral or alkaline take up extra uric acid. The 

 less acid the urine the more uric acid, as a rule, it will dissolve. Dilute urines 

 when considered in proportion to their concentration show much greater solvent 

 power than less dilute urines. 



" Some urines dissolve so much uric acid that they come to contain more uric 

 acid than is present in a saturated solution of monosodium urate. In all prob- 

 ability in these cases at least part of the uric acid is in colloidal solution." 



Creatin in human muscle, W. Denis (Jour. Biol. Chem., 26 (1916), No. 2, pp. 

 379-386). — Employing the method of Folin, the author studied the creatin con- 

 tent of samples of muscle obtained at the autopsies of 5 normal individuals 

 and 72 individuals dying from various diseases. Determinations were also 

 made of the creatin in muscles obtained from several autopsies of children.
