distillers' grains, red dog flour, wheat middlings, wheat bran, beef scrap, and 

 mixed feeds. There is also a list of registered feeding stuffs and their guaran- 

 tied analysis. 



Commercial feeding stufEs of Pennsylvania in 1911, J. W. Kellogg et al. 

 (Perm. Dept. Agr. Bui. 223, 1912, pp. 111). — Analyses are reported of cotton-seed 

 meal ; linseed meal ; corn oil meal ; distillers' grains ; brewers' grains ; malt 

 sprouts; gluten feed; hominy feed; corn bran; corn flour: wheat, rye, and 

 buckwheat middlings; wheat, rye, and animal by-products; wheat bran; wheat 

 and rye offals ; buckwheat feed ; alfalfa meal ; beet pulp ; calf meals ; and 

 mixed, proprietary, condimental, and miscellaneous feeds. 



Feeding stuffs, R. H. Carter and S. J. M. Auld {Jour. Southeast. Agr. Col. 

 Wye, 1911, No. 20, pp. 261-2G3). — Analyses are reported of a mixed cake, 

 linseed cake, undecorticated cotton cake, rape nibs, Niger seed cake, meal, cod 

 liver oil condiment, and molasses food. 



Condimental stock foods {Amer. Food Jour., 7 (1912), No. 8, pp. 16, 17). — 

 An editorial which contains a discussion of the significance of the recent de- 

 cision of the U. S. Supreme Court whereby States are authorized to enact and 

 enforce laws relating to condimental stock feeds, and to charge a fee for their 

 inspection. 



Analyses of some fats of the American buffalo (bison), A. H. Schmidt 

 (Jour. Indus, and Engin. Chem., J/ (1912), No. 8, p. 592). — ^Analyses are reported 

 of the fat of steers and of American bison, taken from different parts of the 

 body. 



The chief difference was in the kidney fats, the chemical constants of which 

 are as follows : Buffalo, specific gravity 0.9346, free fatty acids 1.65 per cent, 

 titer 52.2° C, iodin number 29.45, saponification number 199.3; steer, specific 

 gravity 0.933, free fatty acids 0.6 per cent, titer 42.85° C, iodin number 48.86, 

 and saponification number 196. The differences are thought by the author to 

 be due to the difference in size of the kidneys, which in the bison are about 

 one-half the size of the cattle kidneys. 



On the normal presence of manganese in animals, G. Bertrand and F. 

 Medigreceanu (Compt. Rend. Acad. 8ci. [Paris], 154 (1912), Nos. 15, pp. 

 DJfl-O'fS; 22, pp. l!i50-lJi52; Orig. Commiin. 8. Internat. Cong. Appl. Chem. 

 [Washington and New York], 15 (1912), Seet. VII, p. 35).— Traces of man- 

 ganese were found in about 60 species of wild and domesticated animals, and it 

 is therefore thought that its presence has some physiological significance and 

 is not merely accidental, as is commonly supposed. 



The enzmys of the ovaries, W. Lob and S. Gutmann (Biochem. Ztsehr., 

 J,l (1912), No. 6, pp. Ji'io-.'iGO; ahs. in Jour. Chem. Soe. [London], 102 (1912), 

 No. 598, II, p. 783). — Catalase, diastase, lecithase, lipase, urease, nuclease, and 

 proteolytic ferments of the trypsin and pepsin type were found in the ovaries 

 of pigs. Peroxidase, invertase, lactase, glycolytic enzyms, desamidase, and 

 tyrosinase were not detected. 



The behavior of fat-soluble dyes and stained fat in the animal organism, 

 L. B. Mendel and Amy L. Daniels (Jour. Biol. Chem., 13 (1912), No. 1, pp. 

 11-95). — The work of other investigators on this topic is reviewed and ex- 

 periments in feeding dyes to rats, cats, guinea pigs, pigeons, hens, frogs, a 

 cow, and a goat are reported. The dyes used were Sudan III, Biebrich scarlet, 

 indophenol, oil-soluble green, oil orange, blue base, Dandelion Brand butter 

 color, and annatto. 



The results, which in general are comparable to those previously noted from 

 other sources, are summarized as follows: "Some of the fat-soluble dye.s, in- 

 troduced into the organism by various paths, are deposited in the adipose
