The Hydrocldoride, C Ö H 13 K.HC1. — Un mixing concentrated hy- 

 drochloric acid and the hase together, they combined energetically 

 with the evolution of heat, and the mixture solidified. The whole 

 mass was then dissolved in alcohol,and on concentrating the solution 

 nearly to dryness the hydrochloride crystallized out, in an impure 

 slate, in (he form of long needles. The impure sali thus obtained was 

 purified by dissolving it in the smallest possible quantity of alcohol, 

 and then adding ether to the alcoholic solution, by which means the 

 hydrochloride was precipitated in line colourless needles, as it is 

 insoluble in ether. It is exceedingly deliquescent in air. The 

 crystals seem to decompose under a desiccator, as they soon lose their 

 transparency, probably giving off a part of hydrochloric acid. The 

 crystals, dried over sulphuric acid under a desiccator, were analysed :

The low percentage of chlorine, in the above analysis, may 

 possiblv be due to the decomposition of the salt during desiccation.
