its calcium and thereby becomes free paracasein, which is insoluble in brine 

 solution. 



" [The authors] believe that, according to the evidence in hand, the follow- 

 ing equation represents the reaction which takes place where the compound 

 in question is taken into solution by a salt solution : Calcium caseinate + 2 

 NaCl ?=> sodium caseinate + CaCls. [Furthermore] that the mass action, 

 thus represented, is also connected with the pi-ecipitation produced upon add- 

 ing calcium chlorid to the brine-soluble compound after its solution has been 

 freed from excess of chlorids by dialysis." 



Cane sirup making, H, P. Agee {Louisiana Stas. Bui. 129, pp. 5-36, pi. 1, 

 figs. 17). — It is the purpose of this bulletin to point out the most important 

 facts in regard to sirup making to persons who are engaged, or are about to 

 engage in sirup making on a small or large scale. Among its contents are in- 

 cluded data as to the market grading of sirup, making sirup for special markets, 

 the kind of cane to use, milling the cane, clarifying and sulphuring the juice, 

 the use of lime, first evaporation of juice, second evaporation of sirup, cooling 

 and settling of sirup, the equipment of small and large plants, the use of 

 copper piping, containers for sirup, sterilization of sirup for preservation, the 

 canning of sirup, cleanliness in manufacture, dealing with a high-class retail 

 trade, yields to be expected, and how to prevent crystallization in sirup. Ap- 

 pendixes A and B deal with open kettle sugar and molasses, sorghum sirup, 

 fall planting of cane, preparation of land, drainage, off-barring, use of the 

 scraper, fertilization, cultivation, and kinds and amounts of fertilizers. 



The bulletin is illustrated with cuts of machinery and other apparatus used 

 in the industry, and contains a design of a 600-ton plant. 



Sugar-cane wax, G. Bargeb (Roy. Bot. Gard. Kew, Bui. Misc. Infonn., 1910, 

 No. 9, pp. 355, 356; Intemat. Inst. Agr. [Rome], Bui. Bur. Agr. Intel, and Plant 

 Diseases, 2 (1911), No. 1, pp. 178, 179). — ^This is a review of the work of A. 

 Wijnberg, previously noted (E. S. R., 21, p. 710). 



Manufacturing alcohol from sugar beets, A. Koloczek (Ztschr. Spiritusin- 

 dus., 3-'f {1911), Nos. 19, pp. 239, 2.',0; 20, pp. 252, 253; ahs. in Ztschr. Angew. 

 Chem., 24 {1911), No. 32, pp. 15.'f8, i. 5.'/ 9). —This is a detailed description of the 

 process, to which are appended some estimates in regard to the cost of produc- 

 tion as compared with that of alcohol produced from potatoes. Hungarian con- 

 ditions serve as a basis for these figures. 



Bagasse as a paper-making material, von Possanneb (WchnM. Papier- 

 fahrilc, 1,2 {1911), No. 13, pp. 1157, 1158; ahs. in Jour. Sac. Chem. Indus., 30 

 {1911), No. 8, pp. 483, 484). — Bagasse as a source of raw material for white 

 paper was first pointed out by Wrede.« The author agrees with his views, but 

 points out that it is necessary first to separate the small parenchyma cells of 

 the pith from the useful fibers before attempting to bleach the pulp. " Only 

 by a combined acid and alkaline process of digestion can bagasse be used as a 

 raw material for the manufacture of fine white pai)ers."
