810 EXPERIMENT STATION RECORD. 



values of the oils extracted from the seeds of red currants, hips, tomatoes, 

 raspberries, strawberries, and Euonymus europcetts were determined, together 

 with the melting point, iodin value, mean molecular weight, and percentage 

 of unsaponifiable matter of the fatty acids obtained from these oils. 



Characteristics of Japanese tea oil, M. Tsujimoto (Chem. Rev. Felt u. Ilarz 

 Indus., 15 {J 908), No. 9, p. 22h; ahs. in Analyst, 33 (1908), No. 392, p. U4)-— 

 "Two specimens of the seeds from the Japanese tea plant {Tlica sinensis) 

 yielded, respectively, 23.9 and 26.23 per cent of an orange-colored oil with a 

 somewhat unpleasant odor and bitter taste. . . . The oil was readily soluble 

 in the ordinary solvents for fats and it solidified at — 10° C." 



Color reactions of sesame oil with aromatic aldehydes and sugars, C. 

 Fleig {BuI. Soc. Chim. France, 4. ser., 3 {1908), No. 18-19, pp. 984-999; abs. 

 in Jour. Soc. Chcm. Indus., 27 (1908), No. 21, pp. 1012, 1013).— The reactions 

 with aromatic aldehydes are analogous with those obtained with furfurol in 

 the Baudouin test. The intensity and stability of the color reactions may 

 serve for the determination of sesame oil in mixtures with other oils. 



Technical chemists' handbook, G. Lunge {London, 1908, pp. XV +260). — 

 A revised edition of the Alkali Makers' Tocketbook, but enlarged to include 

 chapters on feed-water for boilers, coal gas, calcium carbide and acetylene, 

 fertilizers, aluminum salts, and alumina and calcareous cements. 



Leather trades chemistry, S. R. Trotman {London, 1908, pp. X+290, pis. ^, 

 figs. -fS).— This work is intended to furnish data as to analytical details of 

 modern processes most frequently met with in practice. The following topics 

 are treated : Analysis of fuel, the estimation of nitrogen, preparation of standard, 

 solutions, water, effluents, depilation, deliming, qualitative recognition of tan- 

 nins, analysis of tanning materials, common vegetable tannins, mineral tannage, 

 analysis of spent liquors and tans, oils, soap, varnishes, skins, analysis of 

 leather, fleshings and scutch, glue, benzine, dyestnffs, disinfectants, and anti- 

 septics. A glossary of technical terms used in the tanning industry is appended. 



METEOROLOGY— WATER. 



Weather forefcasts {Lancet [London], 1908, II, No. 22, pp. 1013, 161 4).— 

 This is a review of a paper by H. E. Rawsbn entitled A New Principle in 

 Weather Forecasting and Its Importance in Naval and Military Operations, in 

 which a method of forecasting based upon a 19-year cycle oscillation of the anti- 

 cyclonic belts of the northern and southern hemispheres is proposed. 



The occurrence of the foehn without subsequent precipitation, F. Mays 

 {Ber. Naturw. Med. Ver.' Innsbruck, 31 {1901-8), pp. 121-166).— This article, 

 which is based upon observations at the University of Innsbruck, 1S9T to 1900, 

 deals in considerable detail with the occurrence of foehns in Innsbruck ; the 

 meteorological behavior of foehns with and without precipitation, and the gen- 

 eral distribution of air pressure in such cases; and northwest foehns. The fair 

 weather foehn is a winter phenomenon. It is pointed out that the meteorological 

 conditions connected with it are very different from those accompanying rain 

 foehns, but in the authors opinion offer no safe basis for prediction. 



A hailstorm following the course of an electric transmission-line, J. 

 VioLLE {Compt. Rend. Acad. Set. [Paris], I4I {1908), No. 1. pp. 315-311; abs. 

 in Sci. Abs., Sect. A — Phys., 11 {1908), No. 10, p. 555).— A description is given 

 of a hailstorm which followed closely the course of a 45,000-voIt three-phase 

 transmission-line for a distance of S.7 miles. The observations indicate that 

 the current had some effect in attracting and directing the storm. 



The action of electric power lines on hailstorms, J. Violle {Conipt. Rend. 

 Acad. /Set. [Paris], 14I {1908), No. 25, pp. 1311, 1312; Jour. Agr. Prat., n. ser.,
