No. 3 attacked sodium slightly, although it had been dis- 
tilled over it several times, therefore it is probable that its 
non-agreement with the calculated result was owing to ad- 
mixture with an oxygen compound. From the above 
analysis and boiling points, it is probable that at least two 
polymers of diallyl are formed by the action of sulphuric 
acid upon it. I had not however a sufficient quantity of 
the hydrocarbons to obtain satisfactory vapour density 
determinations, which would at once have settled the 
point. It is nevertheless probable that No. 1 consists of 
two molecules of diallyl condensed into one, and that it 
has the formula C 12 H 20 ; for Schorlemmer, by the action 
of sulphuric acid on hydrocarbons boiling below 1 20° from 
cannel oil, obtained one which boiled at 210°, and the vapour 
density of which showed that its formula was 
In conclusion, I have much pleasure in tendering my 
thanks to Dr. Roscoe and Mr. Schorlemmer, for their kind- 
ness and attention to me throughout the whole course of 
this research.
