On the question of the formation of fat from albuminoids in 

 the animal body, M. Kumagawa {Mitt. med. Fac. k. Jap. Univ., 

 Tokyo, 3 [1891), p. 1; abs. in Chem. Ztg., 19 (1895), iV"o. 16, Repert., 

 p. 58). — The author's experiments were on dogs. They indicated that 

 the animal body is not ca])able under normal conditions of forming fat 

 from albuminoids. When albuminoids are fed in such large quantity 

 that they alone more than fulfill all the food requirements of the animal, 

 the decomi)osition of the nitrogen -free materials of the food nearly 

 ceases, and the fat and the carbohydrates of the food are almost com- 

 pletely stored in the body as fat. 



Soiling crops, 1894, J. Wilson (loica Sta. Bui. 27, pp. 85-104).— 

 To test the value of a number of soiling crops, 6 cows, including 2 Hol- 

 steins, 2 Shorthorns, and 2 Eed Polls, were fed from June 28 to August 

 28 a basal ration of 5 lbs. of hay and 9 lbs. of corn-and-cob meal per 

 head daily, to which the following green crops were added in separate 

 periods of 7 or 8 days : Peas and oats, red clover, fodder from sweet 

 corn, soja bean, and cowpea. The supply of cowpea was so small that 

 only 2 cows (Holsteins) could be fed upon it. The analyses are given 

 of the soiling crops used, and tests of the composite samples of the 

 milk. Data are also given for the yield of milk and butter, and the 

 flavor, volatile fatty acids, and melting point of the butter produced 

 on each soiling crop. The results are summarized below: 



Average results with soiling crops. 



As the cowpea was fed to only 2 cows, the data are given for these 

 2 cows while receiving corn fodder, for comparison. 



"The soja Lean makes butter of a superior flavor; the creamery experts pronounced 

 it equal to butter from corn. . . . 



"The cows did not eat it readily at first, but after getting it sprinkled with bran, 

 and salt for a few days they ate it readily. While getting accustomed to it the milk 

 flow shrunk consiflerably, but at the end of the test period, August 19, they had 

 reached a larger flow than at any time during the feeding of sweet corn, and, not- 

 withstanding the shrinkage while getting used to it, the average daily yield of but- 

 ter fat reached 3.97 lbs., and the last 4 days of the test went over 4 lbs. This 

 shows the value of plants richer in protein than corn is." 



The investigation of the several breeds of dairy cattle with 

 reference to their relative value in the production of milk, but- 

 ter, and cheese, P. Collier {New York State Sta. Itpt. 1893, pp. 10-
