Diamylaniline boils between 275® and 280° : the small scale upon which I had to 
work prevented me from determining it more accurately. It is interesting to see how 
very little the boiling-point is raised by the introduction of the second equivalent of 
amyl, when compared with the effect produced by the insertion of the first. The 
same remark applies to the ethylanilines.

UPON Ethylaniline. 
Amylethylaniline {Amylethyloplienylamine ) . 
It remained now only to analyse a basic compound in which the three equivalents 
of the ammonia- hydrogen should be replaced by three different radicals. I found in 
amylethylaniline a substance similar in composition to methylethylaniline, but which 
by its properties admitted of a rigorous analytical examination. 
Amylethylaniline is formed without difficulty by the action of bromide of ethyl 
upon amylaniline. The mixture having been exposed to the heat of the water-bath, 
the conversion was found to be complete after two days. When purified in the usual 
way, amylethylaniline forms a colourless oil, boiling at 262®, only 4° higher than the 
amyl-base. The properties of this substance are analogous to those of the other 
bases. It forms a beautiful crystalline hydrochlorate and hydrobromate ; the pla- 
tinum-salt is precipitated in form of a light orange-yellow pasty mass, which rapidly 
crystallizes. This salt fuses at 100®. By analysis of the platinum-compound I was 
enabled to fix without difficulty the composition of the base, which is represented by 
the formula
