Sulphate of Narceine is deposited from its solution in tufts of silky needles, 
not differing much in appearance from the base itself. It is of rather sparing so- 
lubility in cold water, but dissolves abundantly in hot. 
Nitrate of Narceine—The nitrate is deposited in radiated groups from a hot 
It is sparingly soluble in the cold. 
Chloride of Platinum and Narceine-—When a solution of chloride of platinum 
is added to hydrochlorate of narceine, the double compound is deposited sometimes 
in prismatic crystals of small size, and sometimes as a crystalline powder, of a 
solution of narceine in dilute nitric acid.
