Coraputing correlation in cases where symmetrical tables are commonly 

 used, H. S. Jennings (Amer. A'«7., //J (J'Jll), Xo. oSO, pp. 123-128). — A method 

 of computing the coefficient of correlation from ordinary tables bj' which much 

 labor can be saved in studying assortative mating. See also a note by Harris 

 (E. S. R., 24, p. 375). 



An abac for determining the probable errors of correlation coeflS.cients, 

 D. Heron {Biomctrika, 7 (1910), No. 3, pp. J,ll, .'tl2, chart /).— By means of 

 this abac the probable errors of correlation coefficients can be read off at once 

 correctly to at least two decimal iKtints.

 (i. Cong. Intcniat. Elcvagc et Aliment., 1910, Compt. Rend., pp. 168). — This 

 contains a list of the members, the proceedings of the meeting, and reports of 

 some of the papers read.

 (1. Cong. Internat. Elevage et Aliment., 1910, Raps., pp. 52ff + 63). — This is a 

 rejiort of the papers road ;it tho meeting held in Rnissols, 1010.

 tion of the respiration calorimeter for experiments with farm animals, which 

 the author has recently installed. See also a previous note (E. S. R., .22, p. 375).

 (Wisconsin Sta. Circ. Inform. 22, pp. 109). — This is a report of the feeding stuff 

 inspection of 1910. Analyses are reported of linseed oil meal and cake, cotton- 

 seed meal, distillers' grains, gluten and hominy feeds, wheat bran and 

 middlings, red dog flour, rye feed, barley shorts, buckwheat feed, corn-and-cob 

 meal, germ meal, dried brewers' grains, malt sprouts, alfalfa meal, rye bran 

 and middlings, buckwheat hulls, blood meal, beef scrap, tankage, wheat screen- 

 ings, oat hulls, clover hay, clover straw, marsh vetch (Lathyrus palustris), 

 timothy hay, green silage, ground oats, flax screenings, ground corncobs, 

 ground cornstalks, green sweet com, cocoa bean shells, green clover, and many 

 mixed feeds. 



Licensed commercial feeding stuffs, 1911, F. W. Woll (Wisconsin Sta. Circ. 

 Inform. 2.'f, pp. 1-11). — A list of licensed manufacturers of concentrated com- 

 mercial feeding stuffs for the calendar year ending December 31, 1911. 



The lecithin content of meadow grass, J. Becker (FHhling''s Landw. Ztg., 59 

 (1910), No. 12, pp. J,20-42-',; o&s. in Zenfbl. Agr. Chem., 40 (1911), No. 2, p. 

 144). — An application of Thomas slag was found to increase the lecithin con- 

 tent of fresh meadow grass. 



A contribution to the effect of plasmase, L. Geeve (Berlin. Tterdrztl. 

 Wchnschr.. 26 (1910), No. 23, pp. 46 'i-466).— This preparation was found to 

 contain cinnamic acid, phosphoric acid, and arsenic in organic compounds. In 

 experiments with swine, horses, and one cow the growth was stimulated in the 

 case of only one animal.
