416 EXPERIMENT STATION EECORD. 



The drying of beets, Fabre {Sucr. Indig. et Colon., 76 {1910), No. 10, pp. 

 22J,-2.27; ahs. in Cliem. Ztg., S-'t (1910), No. 120, Repert., p. y/.96).— The author 

 advises pressinj? out the beets twice and then dryhig the mass with exhaust 

 steam. By mixing the residue with finely cut straw a stable, easily trans- 

 portable foodstuff coutainiug 20 to 25 per cent of sugar can be obtained. 



Molasses feeds, R. Yallieb (Rev. G6n. Chim., 13 (1910), No. 23, pp. 367-370; 

 H (1911), No. 1, pp. 9-l.'i, figs. 5). — This is a general discussion on molasses 

 feeds and the methods of manufacture. A complete description of the machinei-y 

 required is given. 



In regard to the preparation of adenin in molasses waste, K. ANDELfK; 

 (Ztschr. Zuckerindui;. Bohmen, 34 (1910), No. 10, pp. .567-569; abs. in Chem. 

 ZentU., 1910, II, No. 9, p. GJ/O). — The author found that by boiling molasses 

 waste with copper sulphate and alkali about 0.05 per cent of adenin separated 

 out. Part of it could be obtained in crystalline form by decomposing tbe copper 

 precipitate with hydrogen sulphid in a concentrated solution. A further 

 0.03 per cent could be obtained from the mother liquor by precipitation with 

 picric acid. 



Yearbook of sugar manufacture, J. Bock (Jahreshcr. Zuckerfahrik. [Stam- 

 mer], J,9 (1909), pp. XI I +361, figs. 25).— This is a retrospect of practically all 

 the important work done in the sugar-producing industry for the year 1909, 

 including agriculture, the manufacture of sugar, the chemistry of sugar, patents, 

 statistics, and sugar legislation. 



The raw materials and methods of Iftie soft-drink industry, H. Goettleb 

 (Pure Prodiicts, 6 (1910), Nos. 2, pp. 6J,-71; 3, pp. 120-127; /,, pp. 178-184; 5, 

 pp. 235-241; 6, pp. 320-323; 7, pp. 373-378; 9, pp. 501-506; 10, pp. 567-576; 11, 

 pp. 635-639; 7 (1911), No. 1, irp. 4-10).— This is a description of the methods 

 used for the production of various nonalcoholic drinks. 



On apple aroma, E. Walter (Pure Products, 6 (1910), No. 12, pp. 696-700).— 

 The rational manufacture of apple extract from the fresh or dried apple peels is 

 discussed. 



Alcohol from the carob bean, H. H. Morgan (Jour. Indus, and Engin. Chem., 

 3 (1911), No. 2, p. 139). — The tree upon which this bean grows is a leguminous 

 evergreen and a habitat of Spain, Italy, and the Levant. The bean, which has 

 hitherto been used as a food for animals, is from 6 to 8 in. long and about 1 

 in. wide. 



" Experiments have lately been made in Spain to obtain alcohol from this 

 bean. After triturating the fruit it was immediately placed in hot water to 

 steep and the sugar or glucose extracted by means of a current of water. The 

 liquid resulting from the process was then allowed to ferment, the glucose thus 

 being transformed to alcohol, which was later distilled. It was found that 

 2.3 qt. of pure alcohol could be obtained from 22 lbs. of the beans." 



A factory has been erected at Faro, in Portugal, to manufacture alcohol 

 from these beans. 



[A new plant wax], Olsson-Seffer (Bui. Imp. Inst. [So. Kensington], 7 

 (1909), No. 4, pp. 410, 411; abs. in Oil, Paint and Drug Reporter, 78 (1910), No. 

 12, p. 28H; Chem. Ztg., 34 (1910). No. 138, Repert., p. 567).— A new wax is 

 described, which is obtained from the fruit of Myrica jalapensis. It is used by 

 Indians and sold in Mexico for candy manufacturing purposes. The chemical 

 and physical constants are reported. 



[In regard to candelilla wax], Olsson-Seffeb (Bui. Imp. Inst. [So. Ken- 

 sington], 7 (1909), No. 4, pp. 410, 4II; abs. in Oil, Paint and Drug Reporter, 78 

 (1910), No. 12, p. 28H; Chem. Ztg., 34 (1910), No. 138, Repert., p. 567).— A dis- 

 cussion in regard to the uses, and the physical and chemical constants of can- 

 delilla wax (E. S. R., 23, p. 615; 24, p. 516).
