becomes resinous on exposure to the light. The word ‘“‘globulus ” 
is taken by many dealers in Eucalyptus oils (in and outside the 
colonies) to be generic, so that many other oils of different species 
of Eucalyptus are sold as if they were the product of Z. globulus. 
In Watts’ Dict., 3rd Suppt., Part i., p. 61, it is stated that 
Faust has found that this oil contains a terpene boiling at 150°- 
151°, another terpene called Lucalypiene boiling at 172°-175°, 
together with cymene, and a camphor-like body, Cy H, O. The 
terpene boiling at 150°-151° is present in small quantity only ; it 
takes fire with iodine, and resinises on exposure to the air. (See 
the remarks on “ Eucalyptus oils ” 
genus.) 
“The oil obtained in a first distillation corresponded in its 
general properties with the commercial French and Californian* 
distillates, but the distillation of it yielded some interesting infor- 
mation. This oil showed a specific gravity of 0.925, and was 
at the commencement of this 
dextrogyre (+ 5°). The specific gravity of the commercial 
varieties referred to varies between 0.915 and 0.925, and though 
they are always dextrogyre, their rotatory power varies between 
1.3° and 15.4°. Six commercial samples examined varied from 
50 to 70 per cent. in the amount of Eucalyptol they contained, and 
as Eucalyptol is optically inactive, this property might be utilised 
in judging the quality of an oil. In distilling the leaves of £. 
globulus, aldehydes of the fatty acids were observed; the presence 
of valeraldehyd was determined with certainty, and apparently 
butryaldehyd, and probably capronaldehyd were also present. 
The greater part of these bodies was dissolved in the distillation 
water, but the valeraldehyd could also be detected in the oil; it was 
also present in two commercial samples of the oil.” (Report of
