    Aq. Destillata.—The most exacting tests have been included for the absence of more than traces of organic matter and Ammonia. It will not be found easy to comply with these requirements, other than by the employment of special distillatory apparatus. Aq. Menth Pip and Aq. Menth Virid.—The strengths have been slightly reduced, namely, from 90 minims to 77 minims of oil per gallon. The waters are now of half the strength of those in the United States Pharmacopoeia prepared by rubbing down the oils with Phosphate of Calcium. Aq. Pimentae.—The Pimento has been reduced from 14 ozs. to 8 02s. per gallon. WINES. Three of the Wines official in the 1S85 Pharmacopoeia have been omitted— those of Aloes, Opium and Rhubarb. The alterations in those retained are not important, and are briefly :— Vinum Antimoniale.—The Tartarated Antimony is now directed to be dissolved in water before addition to the Sherry. Vinum Aurantii.—The requirement that the Wine shall be made in Britain is omitted. The percentage of alcohol remains the same, except that a definite statement is now made that the alcohol is to be taken by volume. This may or may not have been intended in the 18S5 Pharmacopoeia. A test has been added for the absence of Salicylic Acid. Slight reactions are allowed for Sulphites, Sulphurous Acid being the preservative usually employed for this wine. Vinum Coichici.—The Wine is directed to be made by the maceration process, and the volume not finally adjusted as in the 1885 Pharmacopoeia. Vinum Ipecacuanhae.—Now directed to be prepared from the standardized Liquid Extract by dilution with Sherry i to 19. The preparation has been already alluded to under standardization, and it will be found to be very much more active than that made by the process of the 1885 Pharmacopoeia from the dried Acetic Extract. The loss of alkaloid in drying the Acetic Extract has been very frequently commented on. Vinum Quininse.—Now prepared by the addition of Hydrochloride of Quinine in place of Sulphate of Quinine and Citric Acid as formerly. Vinum Xericum.—The percentage of alcohol has been reduced from 17 per cent, to 16 per cent., the statement being made that it isi^^ be taken by volume. A test for the absence of Salicylic Acid is also included. There is no necessity for a wine containing this percentage of alcohol to contain any preservative whatever.
