    pburic acid until it is neutralized and becomes clear. Then boil tbe liquid witb animal charcoal, filter it while hot, and set aside to crystallize. Lastly, drain the crystals and dry them on bibulous paper. By evaporating the mother- liquid more crystals may be formed. Uses and doses, as disulphate of quinia, ClNCHONiN^ Sulphas. B. May be obtained from the mother-liquors of the crystallization of the sulphates of quinine, cinchonidine, and quinidine, by precipitating the alkaloid with caustic soda, washing it with spirit until free from other alkaloids, dissolving in sulphuric acid, and after purifying the solution witb animal charcoal, allowing to crystallize. Dose, 1 to 10 grains. CiNGTJLTTM Antirheumaticum. Maejobxin. Camphor 5ss, benzoin 5j, euphorbium 5j, chloride of ammonium jij. Powder them finely and sprinkle on wadding, which is to be slightly quilted between two folds of flannel, to form a belt, to be applied over the seat of rheumatic pains. Cinoultjm: Meectieiale. Agitate 5iij of quicksilver with gij of lemon-juice; pour off the liquid, and mix the quick- silver with the white of an egg and 9j of tragacanth. Spread on a belt of flannel. CiNNABAEis. E. See HTDEAEaxEi Bistjlphtteetum:. COCAINA. Cocaine. An alkaloid obtained from the leaf of the Erythyoxylon Coca. There are two kinds of leaves in the market, one coming from Peru and the other from Bolivia. The latter are said to be rather richer in alka- loid. The yield of cocaine varies from -02 to 2 per cent. 1. (LossEN.) Coca leaves are exhausted with rain water at the temperature of 60° to 80° C.; the united extracts are precipitated with neutral acetate of lead and filtered; the filtrate is precipitated with a saturated aqueous solution of sulphate of soda, again filtered and concentrated; and the concentrated liquid after being rendered slightly alkaline with carbonate of soda, is shaken 4 or 6 times with fresh portions of ether. The greater part of the ether is distilled off, the residue allowed to evaporate spontaneously, and the impure cocaine remaining behind is freed from a part of the colouring matter by trituration with cold water, after which a solution in hydrochloric acid is placed in a thin layer in a Gbaham's dialyser of parchment paper, when
