drene. The oil was rich in cineol, but neither the terpene 
pinene nor the terpene phellandrene could definitely be 
determined in it. The amount of esters was small, the 
saponification number. being only 3°1 with the crude oil, 
and the higher boiling portion did not become acid when 
distilled under atmospheric pressure. Volatile aldehydes 
were present but only in very small amount. The optical 
activity was but slight and to the right, and the refractive 
index was comparatively low, indicating that there was 
hardly any constituent present having a high refractive 
index. This is also shown by the comparative absence of 
Sesquiterpenes in the third fraction. 
The oil of this species has a marked resemblance to the 
better class Kucalyptus oils, and with present methods it 
would be difficult to detect its presence in those oils if the 
rectified oil was used for mixing, or even to decide the 
identity if it were substituted entirely for the superior 
Eucalyptus oils. The insolubility in 70 alcohol of the 
crude oil, together with its forming a turbid solution with 
excess of 80% alcohol, should be a ready means of detection 
if this is found to be a constant feature with the crude oil 
of this species, but this difficulty could easily be got over 
by rectification. 
The crude oil had a specific gravity 0°9134 at 15°C.; a 
refractive index 1°4665 at 23° C., and a rotation in 100 mm.

only 1°° came over below 172°C. (cor.) but 42% distilled 
between that temperature and 174°C. This fraction had
