yield of oil of 0°42%, varying apparently with the time of 
year, being greatest in the Spring. 
The principal constituent has been found to be elemicin— 
-a somewhat rarely occurring phenol ether—present to the 
extent of 75— 80%, the remainder being pinene, a paraffin, 
sesquiterpene, unidentified alcoholic and phenolic bodies. 
As there is every prospect of the oil becoming an article 
of commerce in the near future, the results obtained to 
date are published as a Part I paper, leaving the examination 
of further supplies of the oil from other districts, together 
with the investigation of the alcoholic bodies, for a later 
‘communication. i 
Experimental. 
The 532 Ibs weight of leaves and terminal branchlets 
yielded on distillation with steam, crude oils, which on 
examination, gave the chemical and physical characters 
shown in the table, page 127. 
On distillation at 10 mm. the crude oils yielded 11% boil- 
ing between 42 - 139° C., and 83% distilling at 139 — 148° C., 
leaving 6% residue in the flask, For the identification of 
the principal constituents the fractions from the Currowan 
oils were used. 
Determination of the Terpene.—The portion boiling at 
42—139° OC. at 10 mm. was redistilled, and the distillate 
coming over below 75° C., equal to about 1% of the oil, and 
having a refractive index of 1°4645 at 20° O. was collected. 
It readily yielded a nitrosochloride, which after purifica- 
tion, melted and decomposed at 109°C. It appears, there- 
fore to be o-pinene. 
Unidentified Aleohol.—A fraction was obtained on recti- 
fication boiling at 95-—109° C. at 10 mm. possessing the 
following characters :-—Specific gravity +3° C. 0°9018; 
optical rotation + 7°6°; refractive index, 20° O. 1°4770. 
‘The quantity was insufficient for identification. :
