    together with the general and abstract processes involved in the same, of all medicinal and pharmacopoeial products which are not of a definite chemical constitution, but mere mixtures of active and inert substances, e.g.^ infusions, decoctions, &c. The modern tendency is to standardise the more important of these products as regards, at least, the active principles which they contain, e.^., Extraetum Nucis Vomicce, Ext. Cinchonce Liquidum, Opium. (c) Dispensing is the art of compounding medicines from magistral formulae (prescriptions). The practice of pharmacy embraces chiefly galenical pharmacy and dispensing,—chemicals, crude drugs, and the active principles dealt with therein being (with but few exceptions) obtained from manufacturers and wholesale druggists. The departments of an ordinary dispensing establishment are usually:— (1) The dispensary proper, where prescribed medicines are com- pounded, and where a sufficient quantity of each drug or prepara- tion is kept in readiness for immediate use, together with the requisite apparatus for their manipulation. In its arrangement, the chief objects are to diminish labour, to prevent mistakes and accidents, ^ and to be such as may be readily understood by new dispensers. (2) The laboratory, where the majority of the galenical prepara- tions are made, having all fixed apparatus properly disposed—an efficient stove with steam and water-bath, a heavy bell-metal or iron mortar, a press, a good working-bench with well-secured racks and shelves for mortars, percolators, funnels, &c.; it should also include a complete set of chemical reagents, test-tubes, dishes, &c., and, lastly, gas, and water-supply and sink. (3) The store, consisting of different apartments:—(a) A Drug- experience, and in some respects are more dependent upon careful intelligent observation and comparison of efiects and results, than is the case in the production of definite chemical products (Professor Redwood on Galenical Pharmacy, Pharm. Jour. [3], vol. xvi. pp. 1010, 1011). 1 Recommendations by the Pharmaceutical Society of Great Britain for the keeping of Poisons.—(1) That in the keeping of poisons, each bottle, vessel, box, or package containing a poison be labelled with the name of the article, and also with some distinctive mark, indicating that it contains poison. (2) Also that in the keeping of poisons, each poison be kept on one or other of the following systems, viz :—(a) In a bottle or vessel tied over, capped, locked, or otherwise secured in a manner different from that in which bottles or vessels containing ordinary articles are secured in the same warehouse, shop, or dispensary ; or (6), in a bottle or vesssl rendered distin- guishable by touch from the bottles or vessels in which ordinary articles are kept in the same warehouse, shop, or dispensary ; or (c), in a bottle, vessel, box, or package kept in a room or cupboard set apart for dangerous articles.
