Obs. The above fluids are rubbed on the barrel (previously well polished and cleaned off with whiting to remove the oil), and allowed to remain on for some hours, or until the next day, when they are rubbed off with a stiff brush. The process may be repeated, if necessary. The barrel is next washed in water in which a little pearlash or soda has been dissolved, and afterwards well rinsed in clean water; it is then polished, either with the burnisher, or with a brush and beeswax. Sometimes a coat of tough shell-lac varnish is applied.
BRUCEA (-sh′ă). False cusparia (which see).

BRUCHPFLASTER—RUPTURE PLASTER (Krüsi Altherr). A spread plaster, the mass consisting of 5 parts Bergundy pitch and 2 parts turpentine. (Walz and Hager.)
Bruchpflaster—Rupture Plaster (Caspar Menet). Machine-made paper covered with thin gauze, and thinly spread with a mass of 9 parts wax, 3 parts turpentine, and 1 part elemi. (Hager.)

BRU′CIA. C23H26N2O4. Aq. [Eng., Fr.] Syn. Bru′cine; Bru′cina, L. An alkaloid discovered by Pelletier and Caventou, in the bark of bru′cia antidysenter′ica, and afterwards associated with strychnia, in nux vomica.
Prep. Ground nux vomica, or the bark of brucia antidysenterica, is boiled in dilute sulphuric acid, and the resulting decoction mixed with hydrate of lime (in excess); the crude precipitate thus obtained is boiled in alcohol (sp. gr. ·850), and the tincture filtered whilst hot. A mixture of crude strychnia and brucia is deposited as the fluid cools, and the remainder is obtained by evaporation. This is powdered and digested in cold alcohol, which dissolves out the brucia; the solution furnishes crystals on spontaneous evaporation. It may be further purified by recrystallisation from alcohol.
Prop. Soluble in 850 parts of cold, and about 500 parts of hot water; freely soluble in alcohol; added to the dilute acids until they are neutralised, it forms crystallisable salts, easily obtained by evaporation.
