    water, to which is added an excess of caustic lime. The precipitate is collected, dried, treated with boilino; alcohol, and filtered. The brucine crystallizes from the filtrate on cooling; it may be purified by recryst:iHization. Cadmii Iodidtjm. B. Formed by the direct combination of iodine and cadmium in presence of water. Cadmii Sulphas. U. S. The metal cadmium is dissolved in nitric acid (diluted with an equal vol. of water), by the aid of heat; carb. soda (in the proportion of 3 parts to 2 of acid) is then added, which precipitates the carh. cad- mium ; this is thoroughly washed, and dissolved in sul- phuric acid diluted with water, then evaporated, and set aside to crystallize. Caffeina. Caffeine, or Theine. Boil pulverized unroasted coffee in distdltd water, strain, and add tribasic acetate of lead to the decoction as long as it throws down a precipi- tate ; pass sulphuretted hydrogen through the filtered solu- tion, refilter, and evaporate, so that crystals may form on cooling. The salts of caffeine may be made by adding to a diluted acid sufficient caffeine to neutralize it, and exposing the solution to a heat of 104° F. Dose, gr. j, every hour or two, in hemicrania, &c. Caiamina Prjjpaeata. L. Burn the calamine (native carbonate of zinc), grind it, and prepare it in the same manner as chalk. See Creta Prseparata. [A large pro- portion of what is sold as Lapis Calaminaris contains little or none of this mineral. It should almost entirely dissolve in diluted sulphuric acid, and the precipitate thrown down from this solution by ammonia or potash should redissolve in excess of either precipitant.] Caicii Beomidum. M. Precipitate a solution of bromide of iron with an excess of slaked lime ; evaporate to dry- ness; treat with water, filter, and again evaporate. Caicii Chiobidtjm. B. Chloride of calcium. Muriate of Lime. Neutralize hydrochloric acid with carbonate of lime, add a little solution of chlorinated lime and slaked lime to the solution, filter, evaporate, and dry at a tem- perature of about 400° F. See Liquor Caicii Cbloridi. Calcii Iodidum. From iodide of iron ; ns Caicii Bromidum. Calcii Oxidum. Qiiiclc Lime. See Calx. Calcis AcetaS. Add prepared chalk to acetic (or puri&ed
