    and preparations of this list are termed official. The maximum doses that should be employed and the minimum doses likely to be of effect are indicated in the B.P., which also contains much information to the pharmacist. By means of the Pharmacopceia uniformity and standardisation are obtained, and a valuable means of communication established between the prescriber and the chemist, as all official drugs and their preparations have to be dispensed in accordance with Pharmacopoeia standards. When it is desired to employ non-official pre- parations (and these are frequently useful) their nature must be clearly indicated in the prescription where any doubt exists. (Example: Tr. Aconiti (Fleming), a non-official preparation 12 times as strong as the Tr. Aconiti of the B.P.). Remember that in foreign countries, where patients may require their prescriptions dispensed, there are other Pharmacopoeias differing from the British. Pharmaceutical Preparations. Some drugs, chiefly inorganic, are employed in their natural state, or as substances of definite chemical composition. Example.—Perchloride of mercury, oil of cloves. Others are commonly iised in the form of pre- parations of various kinds, such as :— Aquae (waters) and Liquores (solutions), sub- stances dissolved in water. In the U. S. P. Liquors correspond to the Aquae of the B. P. Injectiones Hyiiodermicae (hypodermic injec- tions), solutions of an active drug for adminis- tration under the skin by means of a syringe and needle.
