possesses a strong ethereal odour like that of peppermint. 
In presence of potassium bichromate and sulphuric acid, it 
yields a blue colour, similar to that produced by perchromic 
acid and common ether. 
This compound has already been obtained by Wurtz 
(Ann. Chim. Phys. (4) III. 174), by treating di-iodhydrate of 
diallyl with silver oxide. He calls it diallyl monohydrate, 
but says further on that this body comports itself as an 
oxide or anhydride (ether), corresponding to dihydrate of 
diallyl

standing to the latter in the same relation 
as hexylene oxide to hexylene glycol, and might be called 
therefore hexylene-pseudoxide. As I have shown that the 
body is not acted upon by potassium, this view of Wurtz’s 
is correct — it cannot be a hydrate, and I therefore propose 
to adopt Wurtz’s second name, and to call it pseudoxide of 
hexylene. 
To throw some light on its constitution it was oxidized 
by heating it in sealed tubes with a solution of potassium 
bichromate and sulphuric acid. On opening the tubes car- 
bonic acid was evolved. Their contents were distilled, and 
the distillate neutralized with sodium carbonate. The neu- 
tral sodium salt was heated in a retort with sulphuric acid, 
by which means a distillate was obtained, which furnished 
a silver salt. The following analysis shows the salt to 
be silver acetate. 
Found. Calculated for silver acetate. 
G4'41 °/ o silver. 64 - 67 °/ Q silver. 
The mother liquor likewise furnished silver acetate. 
Repeated experiments showed that nascent hydrogen 
evolved from sodium amalgam is without action upon 
hexylene pseudoxide. 
Hydriodic acid acts upon the pseudoxide even in the cold. 
A few grams of the substance were heated at 100° with an 
excess of fuming hydriodic acid in sealed tubes for about
