melting at 109°), but contained cineol and some terpineol. 
Between 190—215° 26 per cent. distilled, the fraction con- 
sisting largely of terpineol. The temperature then rose 
considerably, and between 243 — 268° 15 per cent. distilled, 
the fraction consisting largely of a sesquiterpene. 
The three main fractions gave the ieee) results :— 







_ Sp. gr. 15°. | Romeoe hive hel Ref. index at 23° 
First fraction)  0°8832 | +14°3° 1°4628 
Second, | 08857 |. +1175 1°4650 
Third §,,, | .-0°9299-. | .+10:6° 1°4933 

To identify the terpenes the first fraction was first agi- 
tated with a 50 per cent. aqueous solution of po tueeLe 
until all absorbable constituents were removed. 
The odour of terpineol was distinctly marked in the oil 
of the second fraction, and in order to identify this alcohol 
the phenylurethane was prepared, this melted at 111° OC. 
Another portion was shaken with a well cooled mixture of 
equal parts of sulphuric acid and water in smail quantities 
at atime. The unabsorbed oil was removed and the acid 
solution diluted with 4 volumes of water and stood on one 
side. Next day an abundance of crystals had formed which 
were purified and shown to be terpin-hydrate. 
In order to separate the terpineol in a fairly pure con- 
dition another 100 c.c. of the crude oil were distilled, and 
the portion boiling above 190° subjected to distillation 
under reduced pressure; 12 c.c. were thus obtained boiling 
between 108—115° at 20 mm. the bath at 155—160°. This 
fraction had rotation a) +14°8°, and specific gravity 0°932; 
while the odour was distinctly that of terpineol.
