formed are the iodide of tetrallylammonium, which, like the corresponding compound 
of the ethyl- and methyl-series, is but slightly soluble in solution of potassa. It is ob- 
tained pure by exposing it to the air until the potassa is converted into carbonate, and 
then recrystallizing it from absolute alcohol. 
On analysis, 0-3805 grm. of the iodide gave 0-2905 grm. of iodide of silver.

The iodide, treated with oxide of silver, is immediately transformed into the oxide. 
This forms an alkaline solution, which possesses all the properties of the hydi-ated oxide 
of tetrethylammonium. When it is mixed with hydrochloric acid and bichloride of 
platinum, a pale yellow precipitate is obtained, of which the follo-wung is an analysis : — 
I. 0-21 grm. of the platinum-salt gave 0-288 grm. of carbonic acid and 0-0987 grm. 
of water. 
II. 0-311 grm. gave 0-0805 grm. of platinum.

The examination of the allylamines is far from complete ; we have not succeeded in 
separating these bodies from one another with sufficient accm-acy to give a precise
