    S2 residue cool. Let the crystals which form be recrystal- lized, first from rectified spirit, and then from water. [Dose, 5 to 10 gr., as a tonic ; larger doses are laxative.] Betel. A masticatory compound consisting of the leaves of Piper betel, Areca nuts, and lime. Sialagogtie. Bebeeia. Bibirina. Dr. Rodie. The bark of the bebeeru or green-heart tree is first boiled with a solution of carbo- nate of soda, then exhausted with water acidulated with sulphuric acid, and ammonia added as long as it occasions a precipitate. To purify it, Dr. Maclagan directs the impure alkaloid to be washed and mixed with an equal weight of moist oxide of lead (Plumbi oxidum hydratum), and the mass dried and exhausted with alcohol. The clear solution, decanted and evaporated, leaves the alkaloid, which may be further purified by dissolving it in pure ether. Tonic and antiperiodic. Dose, gr. ij—xij. Bebeeia Sulphas. B. Take of bebeeru bark in coarse powder ttj, sulphuric acid f^ss, slaked lime or q. s., solution of ammonia q. s., rectified spirit fSxvj or q. s., ■dilute sulphuric acid q. s., water Cj, distilled water q. s. Add the sulphuric acid to the water ; pour upon the l)ebeeru bark enough of this mixture to moisten it thoroughly; let it macerate for 24- hours ; place it in a percolator, and pass through it the remainder of the acidu- lated water. Concentrate the acid liquor to the bulk of Oj, cool, and add gradually the lime in the form of milk of lime, agitating well, and taking care that the fluid still re- tains a distinct acid reaction. Let it rest for two hours; filter through calico ; wash the precipitate with a little cold distilled water, and add to the filtrate solution of ammonia until the fluid has a faint ammoniacal odour. Collect the precipitate on a cloth, wash it twice with gx of cold water, ■squeeze it gently with the hand, and dry it on the water bath. Pulverize the dry precipitate, put it into a flask with 3vj of the rectified spirit, boil, let it rest for a few minutes, and pour off the spirit. Treat the undissolved portion in a similar manner with fresh spirit, until it is exhausted. Unite the spirituous solutions, add to them 5iv of distilled water, and distil so as to recover the greater part of the spirit. To the residue of the distilla- tion add by degrees, and with constant stirring, dilut*
