Food and efficiency, Martha Tkacy {N. T. Med. Jour., 104 (1916), Nos. 16, 

 pp. 7Jf8. 749; 18, pp. 851-853; 20, pp. 953, 954; 22, pp. 1054-1056; 24, pp. II49- 

 1151; 26, pp. 1245-1247; 105 {1917), No. 2, pp. 75-7S).— This is a summary and 

 digest of recent experimental data on various topics of food and nutrition. 



Food, fuel for the human engine, E. L. Fisk (New York: Life Extension 

 Institute, Inc., 1917, pp. 32, fig. 1). — A popular bulletin on the selection and use 

 of food. Much of the material given is based on a three-weeks' dietary test 

 with 12 young men, in which the cost of food was kept within the limit of 

 25 cts. per day. The menus and recipes used in this test are given and a 

 modification is suggested of the menus for a family including young children. 



Practical suggestions regarding food values and the proper selection of a 

 nutritious and economical diet, A. M. G. Soule (Bui. [Maine] Dept. Agr., 16 

 (1917). No. 1, pp. 36, figs. 2). — This publication contains data regarding the 

 classification of foods and the composition of different food materials and 

 suggestions for the economical selection of the different foods. 



Diet lists, compiled by H. S. Cartek (Philadelphia: W. B. Saunders Co., 1913, 

 pp. VII-{-129). — This is a compilation of different lists prepared primarily for 

 use in the Presbyterian Hospital, New York City. Among the lists included 

 are the regular house diet for each day of the week, which includes the con- 

 valescent and soft diets, and typhoid, salt-poor, purin-free, gastric, diabetic, 

 and other special diets. In the publication are also included a number of 

 special recipes and miscellaneous tables. 



Reports of the [Massachusetts] Commission on Cost of Living, R. Luce 

 ET AX. ([Boston]: State, 1917, pp. 8+7+6+3+14).— This publication contains 

 reports on anthracite coal, bread, the relation of transportation to prices, and 

 department stores, and a final report which summarizes basic causes of the 

 recent increase in prices, and the effect of the war, short crops, abnormal 

 buying, inflation of currency, waste, etc., upon the cost of living. The report 

 contains some recommendations. 



Government control of food supplies in France (Mo. Rev., U. S. Bur. Labor 

 Statis., 4 (1917), No. 4, PP- 525-533). — Information is given regarding the fix- 

 ing of maximum prices for wheat, flour, bread, and other commodities ; munici- 

 pal and cooperative meat markets; the limitation of the sale and service of 

 food, etc. 



The interrelation between diet and body condition and the energy pro- 

 duction during mechanical work in the dog, R. J. Anderson and G. Lusk 

 (Proc. Nat. Acad. Sci., 3 (1917), No. 5, pp. 386-389).— From the experimental 

 data here reported, the following conclusions are drawn by the authors : 



" The accomplishment of a given amount of mechanical work is always at 

 the expense of a given amount of energy, and . . . the amount of energy 

 required for mechanical work is independent of the physical condition of the 

 subject and independent of the quantity of carbohydrate food present in the 

 gastrointestinal tract. . . . 



" Protein in the dietary is primarily for the repair of the tissues. It is not 

 beneficial for the economical performance of work. In excess, it largely in- 

 creases the heat production which a working organism is called on to eliminate. 



" One may reduce the basal requirement for energy by starvation, and this 

 process may economize food in the case of those who do no mechanical work. 



"To accomplish a given amount of work a given amount of fuel energy is 

 required, irrespective of the nutritive condition of the organism. This is of 

 primary importance in the maintenance of armies or munition workers. Car- 

 bohydrate food fuel is utilized without loss." 



The infl.uence of the protein intake on the excretion of creatin in man, W. 

 Denis and Anna S. Minot (Jour. Biol. Chem., 30 (1917), No. 1, pp. 47-51).— Ob-
