JOURNAL of THE CHEMICAL SOCIETY. ABSTRA.OTS OE CHEMICAL PAPERS PUBLISHED IN BRITISH AND FOREIGN JOURNALS. PART I. Organic Chemistry. The Use of Metal-ammoniums in Organic Chemistry. E. Chabla^y (Ami. Chim., 1917, [ix], 8, 145—220).—A résumé oi work already published (compare A., 1905, i, 502; 1906^ i, 722; 1907, i, 53; 1911, i, 939; 1912, i, 3, 244, 528; 19I3, i, 438). W. G. The Method of Pyrogenic Decomposition of Methyl Alcohol at High Temperatures. (Mlle.) Eglantine Peyteal {Compt. rend., 1917, 165, 703—705).—From determinations of the relative amounts of carbon monoxide and formaldehyde obtained when methyl alcohol vapour is passed at different rates through a platinum tube at 1150°, it is shown that the decomposition takes place in two stages which proceed simultaneously. In the first stage, formaldehyde and hydrogen are formed, and the formaldehyde is then decomposed, giving carbon monoxide and hydrogen. W. G. A Hydrate of a Salt Precipitated by Warming its Aqueous Solution. D. Balareff {Zeitsch. anorg. Chcm., 1917, 100, 355—356).—Barium ethyl phosphate, BaC^B^POi, is prepared by warming together on the water-bath for some hours a mixture of ethyl metaphosphate, CgH^POg, and methyl alcohol, and subsequently neutrahsing with barium hydroxide. "When the aqueous solution of the barium salt is warmed, crystals separate, which re- VOL. cxiv. i. b
