due separated by treatment with water into an insoluble bromide of 

 the secondary and a soluble salt, probably the bromide of the primary 

 amine, which, however, could not be obtaiued in quantity sufficient for 

 examination. 



It would seem that the primary anaine can be formed in larger quan- 

 tities under certain conditions, as, on one occasion, a basic oil which 

 solidified after some time was obtained from the wash-waters, but this 

 was unfortunately lost before it was examined, and all attempts to pre- 

 pare a fresh portion were unsuccessful. The mixture of the secondary 

 and tertiary amines, after thorough washing with water, was treated 

 with hot alcohol, which separated without difficulty the more soluble 

 secondary from the but slightly soluble tertiary amine. 



Triparaiodhenzylamine, ( C^.If^fCU.)^N^, was purified by recrystalliza- 

 tion from ether, dried in vacuo, and analyzed.

JProperties. White needles arranged in groups resembling hour- 

 glasses, with an agreeable odor ; melting-point, 114^°; is turned gray 

 by heating, and the melting-point is then much higher ; insoluble in 

 water and cold alcohol ; very slightly soluble in boiling alcohol, easily 

 in ether, benzole, and carbonic disulphide. A chloride could not be 

 obtained by treating a solution of the base with hydrochloric acid. 



Triparaiodbenzylamine chlorplatinate, [( C^H^ICH.^)..NH~\.,Pt Clg, 

 appeared as a bulky yellow precipitate, on adding a solution of platinic 

 chloride to the amine dissolved in ether. It was washed with alcohol, 

 dried t?i vacuo, and analyzed : —
