262 EXPERIMENT STATION EECOED. 



regarding the work of the Commissary Department with respect to changes in 

 rations, a training school for baliers and coolvs, and other topics. 



As regards the use of cans of different sorts, it has been found bj- actual 

 trial " that large losses can be saved to the Government by the use of sanitary 

 enamel-lined cans, and especially for tomatoes intended for shipment to the 

 Philippines." 



In connection with a study of fresh beef and mutton in the Philippines 

 information is given regarding the general appearance of the beef frozen for 

 about 3 years and that frozen for a month, and also the results of a cooking 

 test and data regarding the cost of storage. " While the frozen quarter . . . 

 appeared unattractive and lacked the plumpness, freshness, and bright color 

 found in fresh frozen beef, . . . when cooked it had the flavor, tenderness, and 

 as shown by the chemical analysis, the nutritive value of fresh frozen beef." 



The tests made with beef stored up to 3 years seem to demonstrate " that 

 there is a variance in the percentage of moisture and fat contained in the 

 various samples. This in no way affects the nutritive value of the beef, 

 as the analyses show that the percentage of protein varies but slightly in the 

 6 samples tested. ... 



" Beef in good condition stored in dry, well insulated rooms, kept at a low 

 unvarying temperature, will not mold." 



Taking into account storage, insurance, and interest, 100 lbs. of beef at 

 8 cts. a pound, would represent at the end of 1 year's storage a cost of $9.31 : 

 at the end of 2 years' storage, $10.71 ; and at the end of 3 years' storage, $12.21 . 



During the 3 years beef was held in cold storage " there was a shrinkage 

 of at least 81 per cent, which gives 91.5 lbs. of beef costing 13.34 cts. per 

 pound, an increase of 5.34 cts. per pound over the original cost." 



My system of diet, M. Hindhede, trans, by Marie Dietz (J/em Erndhrungs 

 System-. Berlin and Leipsic, 1911, pp. 196). — A German translation of the 

 author's elucidation of a system of diet which he proposes, with directions 

 for preparing a large variety of dishes. See also a previous note (E. S. R., 

 21, p. 167). 



Lessons in the proper feeding of the family, Winifred S. Gibbs (New York, 

 1911, rev. ed., pp. 53). — This discussion and collection of recipes, like the 

 earlier publication of which it is a revision (E. S. R.. 23, p. 568), is designed 

 for housekeepers with varying incomes, from the very poorest to those having 

 as much as $25 per week. 



Concerning' the food requirements of old men, Elisabeth Koch (Skand. 

 Arch. Physiol, 25 {1911), No. ^-5, pp. 315-330).— The 5 old men studied were 

 from 54 to 79 years of age. On an average the diet supplied 106 gm. protein, 

 55 gm. fat, 361 gm. carbohydrates, and 34 gm. ash, the total energy value 

 being 2,430 calories per day, or, as shown by the digestion experiments, 91 gm. 

 digestible protein, 51 gm. fat, 337 gm. carbohydrates, the total energy value 

 being 2,235 calories, or 33.8 calories per kilogram of body weight. The nitrogen 

 in the urine was determined and showed in every case except one that there 

 were small nitrogen gains. 



The nutrition of public school children iSchr. Zentralst. VolksivohJfahrt, 

 1909, No. Ji, dgms. 2, pp. 170). — A conference report, which includes a paper by 

 M. Rubner on the nutrition of school children. 



The adaptability of the animal body to an oversuflB.cient diet, E. Gbafe 

 and D. Graham {Ztschr. Physiol. Cheni., 73 (1911), No. 1-2, pp. 1-67, pi. 1; abs. 

 in Jour. Chem. Soc. [Loyulon], 100 (1911), No. 587, II, p. 811).— When dogs were 

 overfed for long periods nitrogen was retained while body weight was fairly 

 constant. Apparently, this was due to great activity, increase of oxidation, and
