Somewhat extended experiments by methods of artificial digestion 

 are also reported with the different sorts of meat. From the investiga- 

 tion as a whole the author's principal conclusion is that the importation 

 of refrigerated meat should be increased, since such meat is of satis- 

 factory composition, is easily digestible, and may be kept for an indefi- 

 nite time. The economic importance of refrigerated meat is discussed 

 at some length. 



Nutrition investigations in New Mexico in 1897, A. Goss ( TJ. S. 

 Dept. Agr., Office of Experiment Stations Bui. 54, pp. 20, pi. 1, dgm. 1). — 

 This is a continuation of work previously reported (E. S. R., 9, p. 204). 

 A detailed study was made of the composition of a side of beef taken 

 from a steer representing as nearly as possible the average animal raised 

 upon iSTew Mexico cattle ranges. A dietary study was also made with 

 one of the families previously studied. The usual methods were fol- 

 lowed. The nutrients consumed per man per day were protein 85 gm., 

 fat 71 gm., and carbohydrates 503 gm., with a fuel value of 3,820 

 calories. The cost was 7.1 cts. The total expenditure for food during 

 14 days of the dietary study was $2.78. Of this only 21 cts. was 

 expended for food accessories, coffee being the only such article pur- 

 chased. The waste was estimated to cost but 4 cts. It is noted that 

 the diet falls below the commonly accepted standard in both protein 

 and energy. 



Deep stalls and ordinary stalls for steers, together with feeding 

 experiments -with molasses peat and molasses bran, F. Albert 

 (Landic. Jahrb., 27 (18f)8), N~os. 1-2, pp. 174-188).— -General statements 

 are made concerning the animals fed at the experiment farm at Lauch- 

 stadt, and a number of feeding experiments are reported. A test, begin- 

 ning June 20, 1890, and covering two periods of 49 and GO days, was 

 made with 24 steers, divided into 2 equal lots. One steer was dropped 

 trom each lot before the close of the test. The average weight of the 

 steers was 400 to 500 kg. They were purchased at some distance from 

 the station, and lost 41.23 kg. each during transportation. Lot 1 was 

 kept in deep stalls (see p. 574) and lot 2 in ordinary stalls. During the 

 preliminary period of 14 days the steers were fed a ration of hay and
