Place benz<iiu 5iv in a cylindrical pot of slieet iron, furnished with a flange fit its mouth ; and having fitted the pot into a circular hole in a sheet of pasteboard, interpose between the paste- board and flange a colkir of tow, so as to produce a nearly air-tight junction. Let a cylinder of stili paper open at one end, eighteen inches high, and having a diameter of at least twice that of the pot, be now inverted on the pasteboard and secured to it by slips of paper and flour j)aste. Pass two inches of the lower part of the i)ot through a hole in a plate of sheet tin, which is to be lept from contact with the pasteboard l.iy the interposition of a few corks; and let a heat just sufficient to melt rhe benzoin (that of a gas lamp answers well) be applied, and continued for at least G hours, that benzoic acid may b'c ,'ublimed. Let the product thus obtained, if not quite white, bf pressed firmly between folds of filtering paper, and again sublimed. Dose, from 5 to 30 grains. Acinrii BoEACicuM. M. Wackeneodee.
