TINCTURA OPII CAMPHORATA--CAMPHORATED TINCTURE OF OPIUM Well Known as Paregoric Composed of powdered opium, 4 parts; benzoic acid, 4 parts; camphor, 4 parts; oil of anise, 4 parts; glycerine, 40 parts; diluted alcohol to make 1000 parts. Made by maceration and filtration. DOSE.--Dogs, 1 to 4 dr.; puppies and cats, 2 to 10 m. OPIUM DEODORATUM--DEODORIZED OPIUM Composed of powdered opium, 500 parts; purified petroleum, q. s. Made by repeated maceration, agitation and percolation with purified petroleum benzine. The petroleum benzine removes narcotic and odorous principles, which cause nausea and disagreeable after-effects in opium. Contains 12 to 12.5 per cent of morphine. DOSE.--Same as powdered opium. VINUM OPII--WINE OF OPIUM Composed of opium, cloves, cinnamon and sherry wine. Recommended for dogs suffering from diarrhoea. DOSE.--Same as the tincture of opium. MORPHINA--MORPHINE An alkaloid obtained from opium. PROPERTIES.--Colorless or white, shining prismatic crystals, or fine needles, or crystalline powder; odorless and having a bitter taste; permanent in the air; soluble in 3330 parts of water. The latter are preferable owing to their greater solubility. MORPHINAE HYDROCHLORIDUM--MORPHINE HYDROCHLORIDE Morphine is stirred with hot distilled water, to which hydrochloric acid is gradually added. Morphine hydrochlorate crystallizes out on cooling. PROPERTIES.--White silky, glistening needles or microcrystalline cubes, or a white, crystalline powder, odorless and having a bitter taste; permanent in the air. Soluble in water and alcohol; insoluble in ether and chloroform. DOSE.--Horses and cattle, 3 to 10 gr.; sheep, ¹⁄₂ to 2 gr.; pigs, ¹⁄₁₀ to ¹⁄₂ gr.; dogs, ¹⁄₈ to ¹⁄₂ gr. About one-half of these doses for hypodermic use. MORPHINAE ACETAS--MORPHINE ACETATE Morphine is dissolved in acetic acid and water and the solution evaporated and crystallized. PROPERTIES.--A white or faintly yellowish-white, crystalline, amorphous powder, having a faint, acetous odor and bitter taste. Soluble in water and alcohol. DOSE.--Same as morphine hydrochloride. MORPHINAE SULPHAS--MORPHINE SULPHATE Morphine is stirred into boiling distilled water; diluted sulphuric acid is added until neutralization is attained, and the sulphate crystallizes out on cooling. PROPERTIES.--White, feathery, acicular, silky crystals, or in cubical masses, odorless, permanent in the air, and having a bitter taste. Soluble in water and alcohol, insoluble in chloroform and ether. CODEINA--CODEINE An alkaloid obtained from opium by evaporation of the ammoniacal liquid, after the precipitation of morphine. The residue is added to water, precipitated by potassium hydrate, and redissolved in ether, from which codeine crystallizes out on evaporation.
