[The significance of the chemistry of the proteins in animal nutrition] > 

 T. B. Wood (Trans. Highland and Agr. Soc. Scot., 5. ser., 23 (1911), pp. 8-'f-93).— 

 The aim of this article is to show the practical value to tlie stock feeder of the 

 new points of view of the physioluKical chemists in regard to proteins that 

 the value of a protein may vary greatly according to the amino acids into which 

 it may be decomposed. The quantity of protein necessary for an animal varies 

 considerably, being smaller the nearer the composition of the protein of the feed 

 approaches that of the protein of the animal tissues. As farm stoclc nearly 

 always received a mixed diet, the constituents of which can be varied within 

 certain limits, these mixtures are ordinarily successful because the protein of 

 the several ingredients of the diet are complementary to each other. 



Experiments are cited to show that the successful stock feeder of the future 

 must know something of the nature of the amino acids contained in the proteins 

 of the different feeding stuffs. 



Starch values and fodder units, O. Jensen (Milchw. ZentM., 41 (1912), 

 No. 6, pp. 161-165; Molk. Ztg. Berlin, 22 (1912), No. 19, pp. 217, 218).— This 

 gives the author's views regarding the formulation of rations by means of starch 

 values and fodder units.

The rate of evolution of hydrocyanic acid from linseed under digestive 

 conditions, S. H. Collins (Proc. Univ. Durham Phil. Soc., If (1911-12). No. 

 8, pp. 99-106, figs. 2). — Linseed meal was digested at temperatures approach- 

 ing those of animal life, and the hydrocyanic acid and other volatile products 

 removed by a stream of inert gas. The amount of hydrocyanic acid produced 

 depended upon the amount of cyanogenetic glucosid, the amount of enzym, 

 the temperature, and the degi-ee of acidity of the liquid, as well as on the 

 presence or absence of a number of other substances. The conclusion is
