Peppermint oil industry in Japan, Y. Shinosaki {Jour. Indus, and Engin. 

 Chcin., 5 (1913), No. 8, pp. 606-60S, fujs. 6). — A description, with illustriitions, 

 of a method for preparing peppermint oil in Japan, "The Japanese pepper- 

 mint fields are chiefly located in Hokkaido, Okayaiiia, and Hiroshima prefec- 

 tures." 



The maple sugar industry in Canada, J. B. Spencee {Canada Dept. Agr. 

 Bui. 2B {1913), pp. GJf, figs. 52).— This is a well-illustrated bulletin dealing 

 with the history and extent of the maple sugar industry in Canada. It de- 

 scribes the sugar-making plant, its operation, and the marketing of the sirup 

 and by-products. The beneflts to be obtained in forming cooperative maple 

 sugar makers' associations and inaugurating maple sugar contests are pointed 

 out. 



The g-lucose and starch industry {Thirteenth Census U. S., 10 {1910), pp. 

 429-434). — An account of the extent of the starch and glucose industry in 1909. 



Manufacture of sug'ar from wood, A. Zimmebmann {Jour. Roy. Sac. Arts 

 [London], 61 {1912), No. 3133, pp. 69-81; aU. in Chem. Ztg., 37 {191S), No. 48, 

 p. 49O). — Wood flour when treated in closed retorts with a weak solution of 

 sulphurous acid under a pressure of 6 to 7 atmospheres is decomposed. The 

 resulting products contain about 25 per cent (of the wood used) of sugar and 

 Ti per cent of volatile substances which consist of acetic acid, furfurol, and 

 formaldehyde. The sugar is sold under the name of Bastol and is utilized for 

 the feeding of animals. 



The action of ozone upon cellulose. — Its action upon beech wood (ligno- 

 cellulose), C. Doree and Mary Cunningham {Jour. Chem. Soc. [London], 

 103 {1913), No. 606, pp. 677-686; ahs. in Chem. Zt{/., 37 {1913), No. 73, p. 738).— 

 In the presence of moisture ozone acted very rapidly upon woody substances 

 and caused an evolution of carbon dioxid and acid substances. Much of the 

 wood was converted into water-soluble derivatives and after 12 hours there 

 was a loss corresponding to 40 per cent in its weight. The water-soluble sub- 

 stances consisted of acetic, formic, and other reducing acids. Furfurol was 

 also noted. 



Utilizing wood waste, J. E. Teeple {Jour. Indus, and Engin. Chem., 5 {1913), 

 No. 8, pp. 680-685). — This deals with the utilization of wood waste for prepar- 

 ing paper pulp, ethyl alcohol, acetate of lime, wood alcohol, charcoal, turpen- 

 tine, pine oil, rosin, tar, tar oils, creosote oils, pitch, light oils, wood oils, gas, 

 cattle feeds, acetic acid and acetone, camphor, rosin oils, wood preservatives 

 and paints, disinfectants, sheep dip, perfumes, liniments, and embalming fluid 

 and specialties. The various processes are briefly considered. 



Chemistry in relation to the frozen meat industry of New Zealand, A. j\I. 

 WRmHT {Jour. Indus, and Engin. Chem., 5 {1913), No. 8, pp. 673. 674). — This 

 deals especially with the utilization and shipment of the by-products of the 

 beef industry and the chemical control of this industry. The products con- 

 sidered are frozen meats, oleomargarine, casings, tankage and blood, wool and 

 pelts, preserved meats, and meat extract. 



Butchers', packers', and sausage makers' red book {Chicago, Montreal, and 

 i<}jdney, 1913, pp. 129). — This book contains numerous recipes for preparing 

 meat goods such as hams, bacon, sausages, Bologna, etc. The processes are 

 described in detail. 



About the occurrence of Zygosaccharomyces varieties in wine, Matsumoto 

 and Kroemer {Landtv. Jahrh., 45 {1913), Ergdnzungsh. 1, pp. 106, 107). — Vari- 

 ous kinds of Zygosaccharomyces have been noted in other media but rarely in 

 wine. The results of this investigation show that they often occur in wine 

 and under certain conditions of propagation the organism seems to resemble 

 Debaryoinyces glol)OSUS.
