Notes on Alcoholometry. 11. A. F. Joseph and W. N. Rae. ( J . SOC. Chem. Ind., 1914, 33, 991-992.) (Cf. ANALYST, 1913, 38, 508.)-Further notes on the relative merits of Bedford's tables and the ordinary ones. The former are preferred, on the whole, both at high and low temperatures. The errors or inconsistencies of Bedford's tables rarely exceed the error which would be caused by an error of 1 division in the reading of a hydrometer. G. C. J.

Method by which the Corrected Sikes's Tables in Use in India, for determining the Proof Strengths of Spirits at Temperatures from 40" F. to 100" F. by Sikes's Hydrometer, were ealeulated. F. G. Carter. (J . SOC. Chem. Ind., 1914, 33, 993-994.)-The author describes in detail how these tables were calculated, startjng with the tables in the ANALYST (1880, 5, 42), making use of the formula for expansion of Baumhauer, Recknagel, Kopp, and others, data derived from these formula? being tested by direct experiment.

Ethyl Ester of Linolie Tetrabromide as a Produet in the Analysis of Cottonseed Oil. L. S. Palmer and P. A. Wright. (J . Ind. and Eng. Chem., 1914, 6, 822-823.)-0a brominating the unsaturated fatty acids of cottonseed oil (obtained by extracting the lead soaps with ether and decomposing the ether-soluble portion with hydrochloric acid) the authors obtained, in place of the expected linolic

tetrabromide, a crystalline compound, m.-p. 58” C. This compound on analysis was found to consist of ethyl-bromo-linolate, C,7H,,Br,COOCgHS. The cause of its formation has not yet been ascertaiued, but it appears that the changes which result in its production take place when the lead soaps are in contact with ether.

Occurrence of Methyl Alcohol in Corn Silage. E. B. Hart and A. R . Lamb. (J . Amer. Chem. Xoc., 1914, 36, 2114-2118.)-Hart and Willaman ( J . Amer. Chern. Soc., 1912, 34, 1619), concluded that methyl alcohol was present to the extent of about 0.05 per cent. on the silage mass, but Dox and Neidg (Research. Bull. No. 7, Iowa Exp. Sta.) failed to confirm this. The authors, using the methods of Trillat- Haigh and SanglB-Ferridre-Curniasse and the resorcinal phenol, gallic acid, and morphine tests, have shown that normal silage does undoubtedly contain small amounts of methyl alcohol. In all cases the tests were standardised by using various known mixtures of alcohols, and it is claimed that the number of different tests used precludes the possibility of positive reactions being given by substances other than methyl alcohol. About 300 to 400 grms. of the sample were comminuted in a food grinder, suspended in water, and distilled with steam under reduced pressure of from 30 to 40 mm. to prevent any possible chemical changes .such as might occur a t higher temperatures. About 1 litre was collected, thus obtaining rather less than half of the total volatile acids and alcohols originally present, The distillate, after neutralising with caustic soda, was redistilled under reduced pressure, and then repeatedly fractionated. Further experimental work showed that one source of the methyl alcohol was the action of micro-organisms present in the silage upon the glycine of the corn-proteins, both water cultures and experimental silage tests supporting this conclusion (cf. Ehrlich, Wochensclzr. Brau, 1913, 30, 561, and Zeitsch. anqew. Chem., 1914, 27, 48). H. F. E. H.

Composition of ‘‘ Dead” Rice. G. Silvestri. (Annuli Chim. AppZic., 1914, 1, 212-213.)-The term ‘‘ dead rice ” (grana morta deZ r iso) is given in Italy to im- mature and diseased grains. They are invariably present in unwashed rice, usually to the extent of about 5 per cent., though in certain unfavourable seasons (e.g., 1912) the amount may average over 25 per cent., or in good harvests (e .g . , 1913) may fall to about 2 per cent. ‘‘ Dead ” rice is of a greenish-yellow colour, and has a wrinkled and irregular form. A sample had the following composition : Water, 15.01 ; ash, 1.74 ; nitrogenous substances, 7.18 ; starch, 66-4 ; and fat, cellulose, etc., 9.67 per cent. C. A. M.

Test for Silieates in Soap. H. W. Leitch. (J . Id. and Eng. Chem., 1914, 6, 811-812.)-The test depends on the insolubility of aluminium silicate in a mixture of acetone and water. About 1 grm. of the soap is dissolved in 25 C.C. of water, hydrochloric acid is added, and the liberated fatty acids are separated by filtration. Ten C.C. of the clear filtrate, corresponding to about 0.3 grm. of soap, are treated with 5 C.C. of alcoholic potassium hydroxide solution, evaporated to 10 c.c., and this solution is poured into a test-tube containing 10 C.C. of acetone and 1 C.C. of a solution prepared by dissolving 10 grms. of sodium aluminate and 2 grms. of sodium chloride in 1 litre of water. If sodium silicate was present in the soap, a flocculent gelatinous precipitate is formed. Gelatin, starch, and dextrin, if present in the soap, interfere with the test; the former may be separated by treatment with alcohol or formaldehyde, and the two latter by digestion with diastase. A soap containing alkali carbonates, borax, sodium sulphate, cane-sugar, and dextrose, does not yield a precipitate with the acetone reagent ; if a soap solution does not give a precipitate when added directly to the reagent, silicates are absent ; but if a precipitate forms, the above procedure must be adopted to show if a silicate is actually present.

Estimation of the Proteins in Wheat Flour. G. Silvestri. (Annali Chim. AppZic., 1914, 1, 214-215.)-The gluten from 33.33 grms. of the flour is triturated in a mortar with 70 per cent. alcohol containing 0.3 per cept. of potassium hydroxide, and the mixture (about 80 C.C. of liquid) vigorously shaken with glass beads to com- plete the disintegration of the gluten. After passage of a current of carbon dioxide the liquid is decanted, made up to 150 c.c., and filtered, 50 C.C. of the filtrate evapor- ated, and the residue (gliadin with a little potassium carbonate) dried at 105’ C. and weighed, The potassium carbonate is determined in another portion of the filtrate and deducted to obtain the gliadin. The conglutin is determined by triturating the gluten with 0.3 per cent. potassium hydroxide solution, and adding sufficient alcoho to give an alcoholic strength of 70 per cent. The gliadin and conglutin are then pre- cipitated together by means of sulphuric acid, and separated by washing the precipi- bate (by decantation) with slightly acidified 70 per cent. alcohol. The precipitate is next triturated with alkaline alcohol, and a current of carbon dioxide passed through the liquid, which is allo6ed to stand before filtration. The filtrate is treated with dilute sulphuric acid, and the precipitate of conglutin washed, dried, and weighed.
