    the Philosophical Magazine. These investigations throw light on the ammonia method of water analysis and the m°oist combustion process. Some of the papers have been reprinted in Water Analysis and in Bread Analysis. The papers which have not hitherto been republished in Water Analysis we now reproduce in their chronological order. ON THE ACTION OF PERMANGANATE OE POT- ASH ON UREA, AMMONIA, AND ACETAMIDE IN STRONGLY ALKALINE SOLUTIONS. By J. Alfred Wanklyn, and Arthur Gamgee. From the Journal of the Chemical Society for the beginning of the year 1868. It has been pointed out by Chapman and Smith that permanganate of potash in presence of excess of alkali is an oxidising agent of a most singular kind.i Boiled with oxalic acid, it does not suffer any decom- position ; and, as is seen in the working of the new method for the determination of albuminoid matter in waters, it may be boiled with ammonia without the occurrence of any chemical change. The following experiments on the action of this reagent on urea, ammonia, and acetamide:— Urea=CONHoNH2, Ammonia = NH3, Acetamide = C0CH3NHo, will serve as a contribution to its chemical history. 1 The reference to the action upon alcohol in the paper (j^'i^^^ omit) is not altogether confirmed by later expermients made m our iroiJory Our own unpublished results show that acet,e ac.d ,s pro- duced, but there appears to be no aldehyde.
