same, or greater facility, by exposing the latter base to iodide of ethyl. When sub- 
mitted to the action of iodide of methyl at the temperature of boiling water for three 
or four days, ethylamylaniline exhibits all the phenomena described in the preceding 
paragraph. The lower layer, which solidifies, is a mixture of hydriodate of ethylamyl- 
aniline and iodide of methylethylamylophenylammonium. Sit venia verho !

The corresponding oxide is obtained as the preceding one, namely, by treating the 
clear solution of the two iodine-compounds, previously freed by ebullition from an 
excess of iodide of methyl, or ethylamylaniline, with protoxide of silver, when un- 
changed ethylamylaniline and the base with the long name separate. The latter 
remaining in solution (and forming a very bitter liquid of a strongly alkaline reaction), 
whilst the former is insoluble, there was no difficulty in obtaining a pure platinum- 
salt whereby to prove the composition of the compound in question. This salt is a 
pale-yellow amorphous precipitate, very slightly soluble in water. 
On analysis — 
0’4335 grm. of the platinum-salt gave O’ 1045 grm. of the platinum. 
I collate the percentage number corresponding to this result with the theoretical 
value of the formula —

This compound is certainly remarkable for the diversity of its components, for it 
contains the radicals of not less than four different alcohols ! 
As to the action of heat upon the oxide under examination, there could be scarcely 
any doubt after the result of the preceding investigation. Still I have established by 
experiment that in this reaction olefiant gas is eliminated, whilst a new nitrile-base, 
containing methyl, amyl and phenyl, is generated.
