This essential oil smells slightly of lemons and roses; it tastes 
a little bitter; is somewhat camphor-like; is colourless, and of 
0.881 sp. gr. at 15°. (Wittstein and Mueller.) 
Bosisto says, speaking of some experiments made by him 
(Trans. R.S., Victoria, vol. vi, 1861-4): ‘The material from 
this species had suffered from close packing and length of time in 
transit. The yield from t1oolbs. of leaves was gozs. 3drs. of 
pure, limpid oil, 60z. 2drs. of oil containing resinous matter in 
suspension. Supposing one half of this latter part of the yield to 
consist of resinous matter, the net amount of oil from roolbs. 
will be 1230zs.”

The specific gravity of the essential oil of the leaves of this 
tree is about .g1z. It has a strong camphoraceous odour.

This essential oil is very pale-yellow, thin, of cajeput-like odour, 
but is less disagreeable. It is cooling, and has a mint-like taste ; 
is of 0.917 sp. gr., and boils at 149-°177°.  (Wittstein and Mueller.) 
Later experiments give a specific gravity of .g20. One hundred 
pounds of fresh gathered leaves yielded Mr. Bosisto 1240zs. of oil, 
and he adds that the supply of oil is greater after the leaves have 
changed from obovate to lanceolate, which is the case when the 
trees are from three to four years old. This oil darkens and
