According to SchifF,* stannic tetrachloride forms an addition product 

 with aniline, of the composition (C G H.N) 4 ,SnCl 4 . With diphenyl- 

 amine, however, we obtained by the action of stannic tetrachloride a 

 product, melting at 180-181°, containing no tin ; chlorine was present 

 in large quantity. The investigation of the action of stannic tetra- 

 chloride on organic bases will be contiuued by one of us. 



The above work was done in the Summer School of Chemistry at 

 Harvard College.
