414 EXPERIMENT STATION RECORD. 



(1909), No. 9, pp. 505-512). — Analyses of whole milk, skim milk, buttermilk, 

 and cream are given, which lend support to the efficiency of specific gravity and 

 the ash content of spontaneously coagulated serum in detecting watered milk. 



On the determination of the dirt content in milk, G. Fendler and O. Kuhn 

 (Ztsclir. Uittersitch. Nultr. u. Genussmtl., 17 {1909), No. 9, pp. 513-520, fig. 1).— 

 This article is chiefly a discussion and description of methods for determining 

 the amount of dirt and sediment in milk. 



Analysis of industrial casein, P. Dornic and P. Daire {Bui. Mens. Ojf. 

 Renseig. Agr. [Paris], 8 (1909), No. J,, pp. J,30-Ji37 ; Rev. a6n. Lait, 7 {1909), 

 No. IJf, pp. 328-332). — Analytical data are reported on the determination of 

 water, fat, and ash in casein used for making galalith and other similar 

 products. 



A study of the fatty acids of fish oils, L. M. Tolman {Jour. Indus, and 

 Engin. Chem., 1 {1909), No. 6, pp. 31i0-3^5). — The analytical data reported 

 show that oils from fresh and from salt-water fish and from animals living on 

 fish are remarkably alike in the comiwsition of the unsaturated fatty acids and 

 mixed glycerids present. The unsaturated fatty acids belong to a series entirely 

 different from any known in any vegetal^le or land-animal oils as yet studied. 



Studies of the fat and nitrog'en content of a number of nuts, H. KtJHL 

 {Pharm. Ztg., S-i {1909), No. 6, p. 58; abs. in Chem. ZentU., 1909, I, No. 8, p. 

 676). — Peanuts, Brazil nuts, hazel nuts, and walnuts were included in this 

 investigation. 



On the oil in the fruit of ^sculus hippocastanum (horse-chestnut), M. 

 Stillesen {Chem. Ztg., 33 (1909), No. 55, pp. Ji97, -'i98; abs. in Jour. Sne. Chem. 

 Indus., 28 {1909), No. 10, p. 531). — The following values are reported: Saponi- 

 fication 194..5, iodin 95.4, Reichert-Meissl 1.54, Hehner 92.9, acetyl 13.5, specific 

 gravity 0.92G, refractive index 1.4747. 



The fruit of the Aralia hispida, J. M. Gilchrist {Chem. Netvs, 99 (1909), 

 No. 2579, pp. 211, 212). — Analysis of the fruit of this plant showed that it con- 

 tains 41.72 per cent sugar, 1.5 per cent nitrogen, and 7.98 per cent of oil that 

 had a saponification value of 517. Tartaric and citric acids were present. The 

 ash constituents and other values were also determined. 



[Miscellaneous analyses], E. F. Ladd {North Dakota Sta. Rpt. 1908, pt. 1, pp. 

 29-38). — The substances analyzed at the station last year included formalde- 

 hyde, lignite coal, proprietary disinfectants, flaxseed, sodium arsenite, sugar 

 beets, stock feeds, wheat, bran, and shorts, and alfalfa and linseed meals. 



Annual report of the Swiss agricultural chemical station at Zurich, 1908, 

 A. Grete {handle. Jahrb. Schiveiz, 23 {1909), No. 3, pp. 205-22J,) .—This is the 

 usual annual report and consists chiefly of analytical data regarding fertilizers 

 and feeding stuffs. 



Annual report of the agricultural experiment station at Marburg for the 

 year 1908-9, I'l Haseliioff {Jahresber. Landir. Vers. Stat. Marburg, 1908-9, 

 pp. 20). — This report consists of an outline of the various lines of work under- 

 taken at the station and reports analytical data on fertilizers and feeding stuffs. 



Report of the agricultural experiment station at Rostock from January 1, 

 1907, to June 30, 1908, IIeinrkii {Tiit. Ber. Landir. Vers. Stat. Rostoek, 

 1907-8, pp. 18). — This report consists chiefly of analytical data relating to 

 foods, feeding stuffs, fertilizers, and seed tests of grasses and legumes. 



Report of progress in animal chemistry, R. Maly, R. Andreasch, and K. 

 Spiro (Jahresher. Tier-Chem., 37 (1907), pp. V III -\- 1275). —This is the annual 

 report of progress in the physiological and pathological chemistry of animals, 

 and consists of abstracts of the more important articles published during the 

 year.
