It would, consequently, appear most likely to consider this oil 
as a mixture of these various oxyds and as perhaps still con- 
taining diamylene which had not been attacked during the 
process of oxydation. It possesses a yellowish-green color, a 
penetrating odor of camphor and of mint ; its specific grav- 
ity is less than that of water ; it does not combine with bisul- 
phite of soda and it is in no way affected by a temperature of 
20°C. It appears to be difficult to dry it completely with 
chlorid of calcium, and sodium cannot be employed because it 
affects Mee oil chemically. 
to obtain some farther information pam the 
constitution of this substance, or, at least, to purify it by oxyd- 
izing the diamylene which it possibly still contained, r “teoatee 
6 grms. of the oil with 5 grms. of bichromate of potash, 8 grms. 
of concentrated sulphuric acid and 16 of water in a glass bal- 
loon connected with a reversed ‘ Liebig’s cooler.’ The course 
of this oxydation resembled exactly that of diamylene itself; 
the formation of acids, both oily and soluble in water, and of a 
resinous substance took place, while about 4 grms. of 
which still possessing the characteristic smell and color, now 
showed the following composition 
I, 0:0907 grms. of the substance yielded 02536 CO, and 
0°1104 H, 
II. 0°1098 grms. of the substance yielded 03046 CO, and 
0:1435 H,0.

This composition answers very nearly to the formula C,,H,,O 
(which would be the oxyd of tetramylene) which requires 81-08 
p.c. C, 13°51 H, and 5-41 0. Still it would seem as if merely 
a farther oxydation of the products intermediate between the 
diamylene and the acids described further on, had taken place 
in this instance, and, consequently, no definite formula can as 
yet be assigned to this oil.
