 experience with this test muUr varying conditions. 'I'he iiroportion of carbon 

 bisulpliid and auiyl alcoliol may be reduced to o cc. for r> jjui. of fat. The reac- 

 tion is more sensitive if the test is made with closed tlasks capable of resisting 

 I)ressuro than if made in the usual way. Oils that have been exposed to light 

 and air for some time often fail to react. 



Valuation of willow bark by von Schroeder's hydrometer method, W. 

 Api'ELIus and F. Merkei, (Jour. ,s'oc. Clirin. Iiidii.-!.. 2S (t !)()!)). .Yo. ,',, p. 211). — 

 Willow bark is used extensively in Russia for tanning both light and heavy 

 leather. The authors usetl von Schroeder's hydrometer method for the valua- 

 tion of willow bark and find it to give results similar to those obtained by 

 chemical analysis. 



A sensitive reaction for galalith, I.. Wolter {Chem. Ztg., 33 (1909), No. 2, 

 pp. 11, 12; ahs. in Jour. Soc. Chcm. Indus., 28 (1909), No. 2, p. 101).— The 

 author has found that fuming nitric acid affords a means of detecting galalith 

 when used to imitate tortoise shell. When so treated galalith yields a heavy 

 yellow crystalline powder, while tortoise shell dissolves with the exception 

 of a few transparent scales. 



A vegetable tallow from Irvingia oliveri, C. Crevost (Bill. Econ. Indo- 

 Chine, n. ser., 11 (1908), No. 70, pp. 13-',, i35).— Chemical analyses of the seed 

 and of the oil obtained from the seed of this plant, from which a vegetable 

 tallow is made, are reported. 



[Miscellaneous analyses], D. Hooper {Ann. Rpt. Indian Mus. Indus. Sect., 

 1907-8. pp. 10-18; abs. in Jour. Soc. Chem. Indus., 21 (1908). No. 17, pp. 906, 

 907). — Analytical data are reported of crude lac, shellac, sealing wax, gamboge, 

 turpentine oil, animal oils, tans, brick cutch, 3 new kinos, and of the oils from 

 the seeds of the following plants: Terminalia catappa, T. hclerica, T. clirbula, 

 Cururhita pepo, C. maxima, Cucumis sativus, Luffa wgyptiaca, CitruJJus colo- 

 ci/iithis, Garcinia morella, G. cambogia, G. indica, Mcsiia ferrcn, Sterciilia 

 fiiiidii. Chrozophora rcrbascifoJia, and Lawsonia alba. 



Report of the work in 1908 of the analytical laboratory of Liege, M. de 

 Moi.iNARi (Rap. Trav. Lab. Anal. Liege, 1908, pp. /J).— Analyses of fertilizers 

 and feeding stuffs are reported. In all 7,077 samples were analyzed. 



Report of the agricultural chemist of the Royal Danish Agricultural 

 Society, 1908, K. Eordam (Tids.skr. Landdkonomi, 1909, No. .'/. pp. 21'i-238).— 

 Brief discussions of the main results of examinations made during the year 

 are given, with methods of analysis followed. 



Report of agricultural chemical analyses, Stein's Laboratory, 1907, 

 F. Chrlstensen (Tidsskr. Landokonomi, 1908, No. 5, pp. 299-320). — The report 

 contains a discussion and summary of analytical work done by the Municipal 

 Laboratory in Copenhagen during the year. The total number of samples of 

 feetling stuffs, fertilizers, dairy products, etc., analyzed in 1007 was 20,442, 

 nearly half of the number being cream samples. 



Report of the chemical station at Alnarp, 1908, M. Weibxjll (Mai mo. Ldns 

 Ilii.shall. Sdllsk. Kvrtlsskr., 1908, No. If, pp. 910-928).— The results of chemical 

 analyses of 2,020 samples of dairy products, feeding stuff's, soils, ftn-tilizers, etc., 

 are given and, in some cases, discussed briefly. 



[Miscellaneous analyses] (Jahresber. Landic. Kammer Wiesbaden, 1907, pp. 

 119-122).— Mvdlyaen are reported of fertilizers, feeding stuffs, and other agri- 

 cultural sul)stances. 



Progress in agricultural chemistry in the year 1908, A. Stutzer {Chem. 

 Ztg., 33 (1909). Nos. 23. pp. 217, 218; 2G, pp. 230, 231).— A digest of the litera- 

 ture on this subject.
