    contains supertartrate of potash Prop. Antiseptic, diaphoretic.—Dose, f3j. to fjss. The steam of it may be inhaled in putrid sore throats ; and it may be used exter- nally in bruises, sprains, chilblains, &c.—Off. Prep. Acidum aceticum dilutum ; Cataplasma Sinapis ; Ceratum Saponis; Linimentum JEruginis. [See Aci- dum Aceticum dilutum], ACIDUM ACETICUM FORTIUS. Stronger Acetic Acid, Acidum Aceticum e ligno destillatum. Acetic acid distilled from wood, vulg. Pyroligneous Acid,— Procured from the destructive distillation of wood in iron cylinders. Oxygen, hydrogen, and carbon being liber- ated by heat, reunite and form acetic acid, which comes over at first mixed with thick tarry matter, from which it is in some measure freed by a second distilla- tion. Charcoal from the wood remains in the retort. The acid is next saturated with lime—an impure acetate of lime is formed, which is decomposed by sulphate of soda; sulphate of lime and acetate of soda are the result; the latter is then decomposed by sulph. acid, and the acetic acid is brought over by distillation. It is colourless and transparent, and, when properly prepared, nearly destitute of empyreumatic odour. It is stated by the College that the specific gravity of this acid is to the specific gravity of water, as 1.046 to 1.000, and that 87 grains of the crystals of the subcarbonate of soda are saturated by 100 grains of this acid. The sp. gr. however, forms no cri- terion of its strength. It is usually about six times the strength of acidum aceticum dilutum^ and may readily be reduced to the strength of that preparation by dilution with water.—Prop. The same as common vinegar.—i PotasscB Acetas ; Plumhi Acetas, Being free from the mucilage of common vinegar, it is preferable as a pharmaceutical agent. ACIDUM CITRICUM. [See the preparation in the Pharmacop, ] ACIDUM SULPHURICUM. Sulphuric Acid, com- monly called Oil of Vitriol,—The manner in which it is prepared at Nordhausen, in Germany, consists in distil- ling the sulphate (protosuTphate) of iron. This salt
