The Hydrochloric Acid Salt — CsoHogNH . HCl — formed 

 most readily by conducting dry hydrochloric acid gas into a 

 solution of the base in benzol. The salt was precipitated as 

 a white granular crystalline mass, which was easily decom- 

 posed by water with separation of the base. The mass was 

 filtered off, washed with benzol, and dried over sulphuric 

 acid in vacuum. An analysis of the salt dried at 100° gave 

 the following result : — 



0.2464 gr. substance gave o. mo gr. silver chloride.

The method used in the preparation of this body was the 

 same as that used with the isomeric phenols. The glistening 

 white scales obtained by crystallizing the product of the 

 reaction in hot benzol were easily soluble in hot alcohol and 

 in hot ligroin. Melting point, 78°. 



The combustion gave the following result : — 



0.2 1 71 gr. substance gave 0.6480 gr. carbon-dioxide, and 

 0.1787 gr. water corresponding to 0.1767 gr. C. and 0.0198 

 gr. H.
