HEREZ, ** Behaviour of some Ketons towards Oxi. lising Agents.” The results of a large number of experiments on different ketons of the fatty series, with a variety of oxidising agents, show the corre@ness of Popoff's law, viz., that the alcohol radical containing the least amount of carbon remains joined to CO and forms one acid, while the radical containing the largest amount of carbon is oxidised to the second acid. Oxidation is, however, not confined to the formation of the two acids. In all cases CO; was formed, and lower homologues were present in small quantities. The author finds that all fatty acids are oxi. dised to a certain degree by sulphuric acid and potassium bichromate, contrary to the statement of Thorpe and Chapman. G. NI1eDRIST, * Action of Water on the Halogen Com. pounds of Alcohol Radicals.” Compounds with ethyl, isopropyl, and isobutyl are easily decomposed at 100° to 120°, lorming the corresponding alcohols and hydrogen acids. Amyl chloride is attacked with difficulty, and amyl iodide is scarcely affected. At 150° ethylen-bromide undergoes the following decomposition, attended with a slight forma. tion ef aldehyd +—CoH,Bra+2H,0 = C,H, (OH), + 2BrH. F. ZEIDLER, “ Behaviour of various Amylens towards Oxidising Agents.” . The amylen obtained from optically inactive amyl alcohol with ZnCl, yields carbonic, formic, acetic, propionic, butyric, oxalic, and succinic acids. That obtained by the action of alcoholic soda on amyl iodide prepared from optically inactive amyl alcohol yields carbonic, acetic, propionic, butyric, oxalic, and succinic acids. The amylen prepared by the ation of phosphorus pent. oxide on ethyl-amyl-ether gives carbonic, formic, acetic propionic, and oxalic acids. The Composition and Character of the Water Supplied to London during 1876, By C.”M. Tipy, M.B., F.C.S. London : Wertheimer, Lea, and Co. I'ue London water-supply undergoes abundant supervision Major Bolton examines and reports on behalf of Govern: nent. Parenthetically, and from an absolutely impersonal point of view, we must pronounce it strange that chemical and sanitary questions, such as the purity of a watersupply and the efficiency of methods of sewage treatment, should be referred, not to chemists or to medical praitioners, but to engineers, whether Royal or Civil, From time to time, also, we have Dr. Frankland’s reports on the quality of the Metropolitan waters, and now comes Dr. Tidy’s memoir on the same important subjed, as laid before the Society of Medical Officers of Health, The report of the last named gentleman may fairly be pronounced reassuring. The average amount of organic ammonia—Dby what method determined it does not appear— ranges in the waters delivered by the respective companies from o'002 grain per gallon in ‘the Kent to 0'007 in the West Middlesex, Southwark and Vauxhall, and Chelsea. The hardness before and after boiling varies little respectively from 14-0 and 3°0, save in case of the Kent, where -he figures are 1938 and 5°12. Whether we could by any practicable means produce a supply of water which, by the time it reached the consumer, would be of a decidedly better quality is very doubtful. Nor have we any warrant for supposing that the absence, or even the very great reduction, of the lime salts would be an advantage. Pure aydrogen oxide is a liquid which nature does not provide for us. The waste of water at the present time is pronounced very great, “inasmuch as the quantity delivered on the intermittent system still in use in London is largely in excess of the quantity delivered in large provincial cities in which the system of constant service obtains.” We believe that the intermittent system prevails wherever the water-supply has been committed to the tender mercies of a company, whilst constant service is the rule where the ratepayers take the matter into their own hands. As regards the London water, Dr, Tidy expresses him. self convinced that, * from a medical point of view, no substantial objection can be urged against its wholesomeness for dietetic and culinary purposes.” RUSSIAN CHEMICAL SOCIETY. March. 1877. P. LATSCHINOFF, * Ozidation of Cholesterin.” By the adion of KMnQO, on this substance the author obtains two monobasic acids, cholestenic acid, C,5Hy00,, and oxycholestenic acid, C,5Hy00s, and the dibasic dioxycholestenic acid, C,5H 006. They are all soluble in ammonia, and yield amorphous salts with all metals except the alkalies, The author is led to adopt for cholesterin the formula C,5H,,0[(CsHg)sH,0]. F. BEILSTEIN and A.
