Chemiker Zeitung. No. 31, August 1, 1878. Quantitative Analysis of the Products of the prussiate of Potash Manufacture, with Remarks on the Rational Utilisation of the Residues.—A. Gaw- slowski.—For the examination of the finished cyanide the author recommends De Haen’s method, at least in the absence of sulphides and sulphocyanides. The clear solution of the prussiate is evaporated down, ignited with sulphuric acid, the residue moistened with an alcoholic solution of nitrate of ammonia is ignited again, and dis- solved in hydrochloric acid ; the iron is precipitated with smmonia, washed, and ignited. The residue, minus the weight of the ash of the filter multiplied by 5:28, gives the quantity of a@ual ferrocyanide in the weighed sample The produés of a prussiate works are crude salt, con taining 70 to 80 per cent of ferrocyanide, along with sulphocyanide, sulphide, and sulphate, and mechanically mixed with carbon. Smear salt is the residue from the evaporation of the mother-liquor of crude salt. Blue potash is a potash boiled down from the mother-liquor of smear salt, and contains 50 to 70 per cent carbonate of potash, I to 4 per cent ferrocyanide, and various impuri- ties. The carbonaceous residue sometimes contains from r to 5 per cent of ferrocyanide. The Elberfeld Chamber of Commerce complains that the alizarin manufa@ure suffers greatly from the import futy of 3 marks (3s.) per cwt. upon caustic soda. The meeting of the Society of Swiss Naturalists took place at Berne on the 12th, 13th, and 14th of this month. No. 32, August 8, 1878. An explosion is announced as having happened in Kleinknecht’s Chemical Works, at Brackenheim. Two men were wounded, one—the manager—severely. Prof. Swanberg, of Upsala, the pupil, friend, and suc. cessor of Berzelius, died on the 16th of July, in his 73rd year. At San Francisco the impure gases from cesspools, &c., are to be mixed with coal-gas and burnt in the street-lamps. In some preliminary experiments it was found that the light was not in the least injured by the admixture ! The oil of bankul-nuts (4leurites triloba) is superior to colza for illuminatiug purposes. According to Bottger, an aqueous solution of xantho- genate of potassa is an exceedingly sensitive test for salts of nickel. An intense yellow colouration—or with larger quantities a yellow precipifate—is produced, which does aot disappear on the addition of a few drops of ammonia. Salts of copper yield the same colouration or precipitate with the same reagent, but the colour immediately disap- pears on the addition of ammonia.

MISCELLANEOUS. ¢ One of the most notable improvements in modern Pharmacy.”— Lancet, July 13, 1878. THEVENOT'S GLOBULES differ from the Capsule inasmuch as pure vegetable gum is used instead of gelatine—powders as wel as liquids are encased; from the pill inasmuch as the medicine is preserved without deterioration for an indefinite length of time. * This method of capsulation is most valuable for reduced iron, so apt to deteriorate by exposure.” —L ancet. From every other form inasmuch as ether and the most volatile matiers can be dosed accurately, which can be done by no other method.—See * Report of Academy of Medicine, Paris.” SAMPLES ON APPLICATION. WHOLESALE— H. K. EDGE & CO., 34, Kine WiLLiaM STREET, Lonpon, E.C. Thevenot’s Globules.—M. C. Thevenot, of the Société de Pharmacie, of Paris, has invented a novel form of ad. ministration of medicine, which is, we consider, most valuable for medicines which deteriorate through ex posure or which are of a nauseous nature. The case in which the medicine is enclosed is both soluble and digest. ible. Among other advantages the inventor claims that the most volatile substances can thus be accurately dosed and preserved for an indefinite period, and that the globule, unlike the pill, does not become stale, hard, and gritty.
