    Tests.—Specific gravity TOOG. 440 grains by weight (1 fluid ounce) require for neutralisation 313 grain-measures of the volumetric solution of soda, corresponding to 3-63 per cent, of anhydrous acetic acid. One fluid ounce therefore corresponds to 16 grains of anhydrous acid. Dose.—1 to 2 fluid drachms. Preparations in which Dilated Acetic Acid is tised. Acetum Scillas Liquor Morphias Acetatis ACIDUM ACETICUM GLACIALE. Glacial Acetic Acid. Synonym.—Acidum Aceticum, JEdin. Concentrated acetic acid, corresponding to at least 84 per cent, of anhydrous acid, C4H303 or C4H603. Characters and Tests.—It crystallises when cooled to 34°, and remains crystalline until the temperature rises to above 48°. Specific gravity l-065 to 1*066, and this is increased by adding ten per cent, of water. At the mean temperature of the air it is a colourless liquid, with a pungent acetous odour. 60 grains by weight mixed with a fluid ounce of distilled water require for neutralisation at least 990 grain-measure3 of the volumetric solution of soda. • If a 4luid drachm of it mixed with half an ounce of distilled water and half a drachm of pure hydrochloric acid be put into a small flask with a I few pieces of granulated zinc, and while the effervescence con- 1 tinues a slip of bibulous paper wetted with solution of sub- acetate of lead be suspended in the upper part of the flask . above the liquid for about five minutes, the paper will not i become discoloured. Preparations in which Glacial Acetic Acid is used. Acetum Cantharidis | Mistura Creasoti
