Precipitated Chalk

This is prepared by adding a solution of carbonate of soda to a solution of chloride of calcium (both cold), as long as a precipitate forms. This last is well washed with pure water, and dried out of the dust, as the last. The refuse sulphate of lime of the soda-water makers, which is poisonous in quantity, is often sold (See Nos. 1177, Sc., 1279, &c., and 1285.) for it by the druggists. Pure chalk is wholly 1287. Hungarian Pomade for the Moustache. Melt by a gentle heat 1/2 pound gum-arabic, and 1/2 pound of oil soap, in 1 pint rose water, then add 1 pound white wax, constantly stirring; when of a uniform consistency, add 1 ounce attar of bergamot, and 1/2 drachm attar of thyme, for perfume. If required to be brown, color it with tube-burnt umber; or for black, use tube ivory-black. soluble in vinegar, and in dilute acetic, hydrochloric, and nitric acid, with effervescence. Sulphate of lime is insoluble in these fluids.
