The oxydation—At one time 14 grms, of diamylene were 
mixed with 100 grms. of bichromate of potassa, 150 of sul- 
phuric acid (spec. gravity=0-1842) and 150 of water ; in @ 
second experiment 32 grms, of diamylene, 228 of the bichro- 
then diluted with water and distilled, furnishing a green oil 
to hold some acid in solution ; it was, therefore, neutralized 
with soda, washed with water and dried over chlorid of lime. 
I. 0-1006 grms., taken from the entire quantity of the oil after 
ing with chlorid of calcium, yielded 0-2643 grms, CO 
and 01206 HO. i: ; 
IL. 0-0996 grms., boiling at 140°-160° C., yielded 0-2690 CO, 
_ and 071236 H.O 
III. 01646 grms., boiling at 160°-180° C., furnished 0:4552 
ae CO, and 01974 H,O. 
IV. 02016 frm. boiling at 180°-200° C., furnished 05667 
CO,. The determination of the water was lost,
