multiple allelomorphs, multiple factors, and the factorial hypothesis. A bibliog- 

 raphy relating to the literature is appended. 



The fundamentals of live stock judging and selection, R. S. Curtis (Phila- 

 delphia: Lea & Febiger, 1915, pp. X +17-455, figs. 180).— A general treatise on 

 methods of live stock judging. 



The value of broom millet seed compared with sorghum (Agr. Gaz. N. S. 

 Wales, 26 {1915), No. 8, p. 698). — Analyses of mature sorghum seed and broom 

 millet seed are given as moisture 12.42 and 12.71 per cent, protein 7.1 and 9.06, 

 ether extract 3.13 and 2.6, nitrogen-free extract 71.34 and 61.84, crude fiber 3.6 

 and 8.53, ash 2.41 and 5.26, nutritive ratio 1 : 11.4 and 1 : 7.4, and nutritive value 

 85.5 and 76.7, respectively. 



Report of analyses of commercial feed stuffs (La. Dept. Agr. and Immigr. 

 Feed Btufjs Rpt. 1913-1^, pp. 152). — Analyses made by the Louisiana State 

 Experiment Station are reported of cotton-seed meal, rice bran, rice polish, 

 wheat bran, shorts, middlings, screenings, corn chops, molasses feed, unbolted 

 corn meal, hominy feed, brewers' grains, meat scrap, alfalfa meal, and various 

 mixed and proprietary feeds. 



Feeding stuffs (Landw. Jahrh. Bayem, 4 (1914), pp. 425-436, 512-517, 534- 

 549, 783-791). — Analyses are given of rape seed, rape seed cake and meal, 

 sesame cake and meal, peanut cake and meal, linseed cake and meal, sunflower 

 seed meal, palm nut cake and meal, soy bean meal, coco cake and meal, rice feed 

 meal, brewers' grains, malt sprouts, fish meal, blood meal, ground malt polish 

 dust, germ oil meal, cacao shell, and turf molasses. 



The starch equivalent theory, J. A. Mubkay (Jour. Agr. Sci. [England], 

 7 (1915), No. 2, pp. 154-162, fig. 1). — In this article the author points out the 

 imperfections of the starch equivalent theory and comments upon the efforts 

 of Wood and Yule (E. S. R., 32, p. 166) to correct the Kellner standard. He 

 proposes that the feeding standards be superseded by formulas. These should 

 be in terms of " total digestible nutrients " with given protein ratios for main- 

 tenance, growth, work, fattening, and milk production. 



The maintenance ration of oxen and the starch equivalent theory, E. T. 

 Halnan (Jour. Agr. Sci. [England], 7 (1915), No. 2, pp. 163-174).— The author 

 takes exception to the suggestions offered in the paper noted above and advo- 

 cates the continued use of the Kellner system of starch equivalents. A very 

 complete discussion is given of the development and application of the starch 

 equivalent theory. 



The mineral content of feed stu:£Es in relation to the weather and the 

 mineral requirements in cattle feeding, E. Kunze (Mitt. Landw. Inst. Leipzig, 

 No. 12 (1914), PP- 61-96).— Analyses of the P2O5, CaO, and KaO contents of the 

 grain, straw, and chaff of oats during different seasons of the year and under 

 various methods of fertilization are reported. A resumg of literature on the 

 subject of the effect of the mineral content of plants on the animal framework 

 is also given. 



The improvement of native cattle in Jamaica, H. H. Cousins (Bui. Dept. 

 Agr. Jamaica, n. ser., 2 (1915), No. 8, pp. 338-3Jf5, pis. 10).— It is stated that 

 an element of zebu blood or of the Indian breeds of cattle is necessary if Euro- 

 pean breeds are to be hardened sufficiently to do well under tropical conditions 

 in Jamaica. The Shorthorn and the Hereford have a tender white skin which 

 is very susceptible to the influence of the tropical sun. The zebus on the other 

 hand, even when externally light colored or white, have a black sun-resistant 

 skin. The influence of the zebu blood is so marked that one-eighth of it is 

 enough to give a short-haired character and a darkening of the skin to a com- 

 posite animal while preserving in a marked degree the beef qualities inherent 

 in the other introduced breed.
