[Food of upper Yukon natives]. F. ScuxirrrKK { SDiitlisn. Mi.sc. CoUcct.. .',6, 

 Xo. //. pjt. 6. 7). — The diet of these natives consists of fish. game, and berries, 

 supplemented by vegetables bought at local stores. I'ntil recently they lived 

 exclusively on animal food, but now demand vegetable food. The Mackenzie 

 River natives, on the contrary, live almost entirely on meat. The author states 

 that they are robust and healthy. 



Notes on the ration of Cuban workmen, H. Ferrkr (An. Acad. Cicn. Un- 

 hana, 47 (1910), May, pp. 1,1-08, pi. 1. pg.s. 3).— All parts of the island are con- 

 sidered in the author's study of dietary conditions in Cuba. In general he con- 

 cludes that the average ration is improperly proportioned and poorly selected, 

 and makes recommendations for securing a more economical diet. 



According to the data which he simmiarizes regarding Cuban conditions, a 

 typical man without work consumes a diet supplying 67.68 gm. protein and 1,708 

 calories of energy. The diet of a physician 32 years old, weighing 58 kg., sup- 

 plied 88.50 gm. protein and 1,949 calories; the ration of a Cuban at moderate 

 work 93.15 gm. protein and 2,326 calories ; and the ration of a Cuban at severe 

 work, 111.17 gm. protein and 2,778 calories. In the study of siiecial diets he 

 states that the ration of Cuban soldiers in time of peace supplies 147.9 gm. 

 protein and 3.999 calories, and the ration of prisoners 76.2 gm. protein and 

 1.7S1 calories. 



The possible relation between the high cost of living in cities and the high 

 death rate from tuberculosis is discussed, as well as other topics which have to 

 do with the general subject. 



Manual for army bakers, H. G. Sharpe et al. (War Dcpt. \U. .S'.], Off. 

 Cam. Goii. Doc. 358, pp. 89, figs. 14) • — This contains an outline of the chemistry 

 of bread making, and describes the equipment and processes used in army post 

 bakeries and also field baking and field bakery equipment. 



Diet in training (J/ecZ. Rcc. [X. T.], 7,S (1910). Xo. o, p. 19',).— X discussion 

 of diet in training in which the author quotes from a paper read by H. I. Gillett 

 before the Oxford Medical Society, June, 1910, to the effect that the majority of 

 Oxford rowing men consume on an average 169 gm. protein daily. The possi- 

 bilities of harmful results from the consumption of an excess of protein are 

 considered. 



" The point is how to discover what constitutes an excess of protein and to 

 find out whether a hard and fast rule can be laid down with resi)ect to the diet 

 of athletes. Judging from experiments and tests which have be(>n made up to 

 the present time, it may be stated with emphasis that no arbitrary rule can be 

 deduced from these and it seems likely that the diet of athletes must be regu- 

 lated according to the idio.syncrasies of individuals under the direction of 

 medical men or skilled trainers." 



The action of sodium benzoate and benzoic acid on the human organism, 

 C. A. Hekter (\X(ir ) or/.l. 1910. pp. IS). — In this publication the author replies 

 to criticisms which have been made of the report of the Referee Board appointed 

 to study the action of sodium benzoate, and gives rea.sons for his belief that the 

 conclusions of this board are reliable and trustworthy. 



The influence of oxygen inhalations on muscular work, L. Hill and M. 

 Flack (Jour. Physiol., 40 (1910), Xo. 5, pp. 347-372, figs. 2, dgms. 5).— A series 

 of experiments on 12 subjects led to the following conclusions among others: 



"The inhalation of oxygen lessens the discomfort of forced breathing. It 

 enables young men with a great power of pulmonary ventilation to go on with 

 forced breathing for as long as 19 minutes, and to wash the 'COj out of the 

 body till the alveolar tfcngion sinks to as low as 1.47 per cent. . . .
