MOLECULAR CONSTITUTION OF THE ORGANIC BASES.

After having ascertained by treatment with ether that the solution did not retain a 
trace of diethylaniline, it was saturated with hydrochloric acid and mixed with 
bichloride of platinum, when at once a pale-yellow, apparently amorphous precipitate 
was thrown down, which was scarcely soluble in water and insoluble in alcohol and 
ether, 
0*4055 grm. of platinum-salt gave 0*1045 grm. of platinum.

I have not examined any farther the compounds of this base ; I have only ascer- 
tained that the sulphate, nitrate, oxalate and hydrochlorate crystallize, although with 
difficulty. 
When oxide of phenylotriethylammonium is submitted to the action of heat, it 
yields, as might have been expected, water, olefiant gas and diethylophenylamine 
(diethylaniline).

The olefiant gas was identified by the conversion into the bromine-compound, the 
diethylaniline by the analysis of the characteristic platinum-salt, 
0*2965 grm, of platinum-salt gave 0*0820 grm, of platinum. 
This corresponds to 27*65 per cent, of platinum.

Action of Iodide op Methyl upon Ethylamylaniline. 
Ethylamylaniline, which I formerly obtained* by the action of bromide of amyl 
upon ethylaniline, or of bromide of ethyl upon amylaniline, may be formed with the
