Spirit of wine dissolves out a small portion, which, on evaporation, leaves a thick oleo-resinous substance, having a rancid smell. Ether leaves a pleasant-smelling resin, somewhat resembling camphor. The remainder is nearly insoluble in liq. ammoniae, liq. potassae, more soluble in nitric acid, and well deserves to be further examined. [I] Qy. Confectionery? [J] Qy. Confectioners?
