ESSENTIAL OIL OF KUNZEA CORIFOLIA. 205 
Attempts to prepare the nitrosochloride and nitrosate 
were unsuccessful but the evidence so far obtained indicates 
that the sesquiterpene occurring in the oil is probably 
identical with cadinene. : 
Alcohols.—The saponification values after acetylation of 
the crude oils indicate the presence of fair quantities of 
alcoholic bodies in the oils. The only portion, however, in 
which these bodies appeared to be concentrated was a 
small fraction boiling between 160—185° C. This fraction 
was shaken with 50% resorcin solution, and on steam dis- 
tillation 5 c.c. of a light blue oil were obtained which had 
the characteristic fragrant odour possessed to a lesser 
degree by the crude oil. The constituent thus obtained 
had the following characters:—Specific gravity 73°C. 0°9029, 
optical rotation +6°2°, refractive index at 20° O. 1°4685. 
Since the quantity obtained was so small, no further 
information is at present available, and further work will 
be undertaken with a view to determination of its identity, 
the results of which will be communicated later. 
Esters.—In addition to the constituents enumerated 
above, small quantities of acetic and butyric acid esters 
were found to be present in the oil. 
In conclusion I have to express my best thanks to Mr. 
A. R. Penfold, F.c.s., Economic Ohemist, for much valuable 
advice and assistance during this investigation.
