![L — Simple oinlmenf. gxx. : acetate of lead, in fine powder, %i; mix them thoroughly, E )• A soothing and astringent application to irritable ulcers, or excoriated parts. . iNCOMPATinLES.—Hard water; the mineral acids and their salts; citric, lartaiic, and carbonic acids, and their salts ; the alkalies ; lime- water ; iodide of potassium ; tincture of galls; opium; albuminous liquids ; and various vegetable infusions. When an overdose of acetate of lead has been taken, sulphate or phosphate of soda, and sulphate of magnesia, are the best antidotes; their administration should be succeeded by emetics and afterwards by active purgatives, and opium. Plumbi carbonas, [U.S.] D. L. E. Carbonate of Lead; White Lead; Cerusse. Preparation—An article of the Materia Medica. On the large scale it is generally | repared, by expo-ing bars or plates of lead to the fumes of strong ace ic, or pyroligneous acid, disengaged from the iron pots in which it is contained, hv placing them in a mixture of dung and tanner's refuse. The carbonate fo'ms on the surface of the lead, and is detached by rolling the plates under water. On the continent it is also frequently prepared, by t>ar slitting a current 01 carbonic acid gas through a solution of acetate of lead. Physical Properties.—A heavy, white, obscurely crystalline pew- der ; sometimes met with in greyish-white, chalk-like masses; in- odorous, and tasteless. Chemical Properties.—It is composed of 1 eq. of protoxide of lead, and 1 of carbonic acid, (PbO, CO2). Exposed to heat it parts with its carbonic acid, and is converted into the yellow oxide of lead. It is insoluble in water, but dissolves in nitric acid with effervescence. Adulterations.—Carbonate of lead is very much adulterated ; the impurities generally found in it are chalk, sulphate of baryta, and sul- phate of lead ; the two latter may be detected by their insolubility in dilute nitric acid. - The presence of chalk may be discovered by dis- solving the suspected specimen in dilute nitric acid, throwing down the lead from the solution by sulphuretted hydrogen, filtering, and adding solution of oxalate of ammonia ; when,*lrany chalk has been present, a white precipitate (oxalate of lime) will be produced. Therapeutical Effects.—Carbonattbrflead is more apt to pro- duce lead-colic than any other of the pmALons of this metal, it is consequently never used internally. PR* k-Jtcts as a sedative- astringent, and is employed in the lur^Paf ointment to promote the cicatrizaticitT of excoriated parts lit ulcerations. Spread on leather, it is said to prove useful applied over the seat of the pain in local neuralgia.—Unguentum plumbi carbonatis, D. E. (Carbonate of lead, in very fine powder, §ij. ; ointment of white wax, Ibj. -make into an ointment, D.— Simple ointment, |v. ; carbonate of lead, |i. ; mix thoroughly, E.) Plumbi diacetatis (subacetatis, [U. S.] D.) liquor, D. L. Plumbi diacetatis solutio, E.
