    THE LONDON PHARMACOPGIA. WEIGHTS, MEASURES, &c.

Gr. xx. Grains ( One Scruple, 9 Di} parr es Site One Drachm, 3 5vi1j Drachms One Ounce, 3 5xij Ounces J L One Pound, tb. We have annexed the characters by which each weight is ordinarily denoted. Our Measures of Liquids are derived from the last statute gallon; and our divisions of it are the following :— Table. mlx Minims — 7 One Fluidrachm, fs f5viij Fluidrachms ( make 3 One Fluidounce, £3 f%xx Fluidounces One Pint, O Oviij Pints J One Gallon, C We have annexed the usual characters of each measure. Care must be taken that medicines be not contaminated with the material of the vessel in which they are either prepared or preserved. All acid, alkaline, or metallic preparations, and salts of every kind, should be kept in stopped glass-bottles; and, for some of them, black or green glass is indispensable.
