ammonia on the iodide of allyl, when digested with a second quantity of iodide of allyl, 
is rapidly changed into a mass of hydriodates of new compounds. 
This crystalline mass evidently contains a considerable quantity of the hydriodate of 
diallylamine ; but to succeed in separating it from this very complicated mixture would 
have required a considerable quantity of substance. We have therefore been satisfied 
to determine by a few experiments the existence of triallylamine and the oxide of 
tetrallylammonium. 
Triallylamine. 
The oxide of tetrallylammonium, to which we shall presently allude, submitted to the 
action of heat, is decomposed vdth liberation of a basic oil. The experiment was not 
made on a sufficient scale to admit of the study of the complementary products. The 
perfect analogy of the oxide of tetrallylammonium with the corresponding ethyl-com- 
pound, leaves no doubt respecting the nature of the basic substance which results from 
its decomposition by the action of heat. This body must obviously be triallylamine^ 
and experiment has confirmed this anticipation. The base saturated with hydrochloric 
acid and mixed with bichloride of platinum, deposits a yellow platinum-salt, the analysis 
of which has furnished the following results : — 
0T815 grm. of the platinum-salt gave 0-0515 grm. of platinum.

Hydrated Oxide of Tetrallylammonium. 
The chief product of the action of ammonia upon iodide of allyl is a magnificent 
crjstalline compound, which is deposited from the solution resulting from the reaction. 
We have treated iodide of allyl with ammonia in sealed tubes, but this is not necessary, 
for iodide of allyl is rapidly attacked even by an aqueous solution of ammonia at the 
common temperature. By contact for a few days a large quantity of the iodide dissolves, 
and the solution sometimes becomes a solid mass. If no deposition of crystals take 
place from the solution, it is only necessary to add a concentrated solution of potassa ; 
this causes the separation of an oily layer which speedily solidifies. The crystals thus
