compounds were prepared. With the exception of the 

 platinochloride of dithymylamine, the products were well 

 crystallized. 



A summary of the work would be incomplete without 

 mentioning the fact, that efforts to obtain picrates of diphe- 

 nisamylamine and dithymylamine were unsuccessful. An 

 analysis of the products obtained by the action of an alco- 

 holic solution of picric acid upon an alcoholic solution of 

 the aforementioned bases corresponded quite closely with the 

 theory for picric acid. In crystal form and melting point 

 the substances exhibited marked differences. The products 

 will be further examined, with the hope of determining what 

 molecular arrangement took place.
