haviour with phosphoric acid and the preparation of the 
iodol derivative melting at 111 — 112° O. confirmed its pres- 
ence. Quantitative estimations made, using the fraction 
of oil boiling below 190° OC. at 760 mm., showed the presence 
of about 8% of this constituent in the crude oil using the 
phosphoric acid method, and about 147% by the resorcin 
method. 
Determination of Terpineol.—In working up about 600 
c.c. of the crude oil for constituents distilling above 200°C. 
a fraction of 15 c.c. boiling at 99—101° C. at 10 mm. was 
obtained having the following constants :—Specific gravity 
t?° O. 0°9296 ; optical rotation +9°, and refractive index 
20° OC. 1°4838. On shaking with 57% sulphuric acid crystals 
of terpene hydrate were obtained melting at 117—118° C.; 
the resulting terpin then melting at 104° O. A nitroso- 
chloride was also prepared which on recrystallisation from 
etbyl acetate melted at 112—113° C. The alcohol is there- 
fore « terpineol. 
Determination of Sesquiterpene and Sesquiterpene 
Alcohol.—Repeated fractionation of the high boiling por- 
tions at 10 mm. finally yielded the following distillates, 
which in the case of the sesquiterpene were carried out 
over metallic sodium :— 
Boiling point at10 mm. 129—132° C, and 132-135" C. 
Specific gravity at 73° C. 0°9239 0°9284 
Optical rotation + 14°45 + LOrra 
Refractive index 20° C. 1°5037 1°5057 
No solid derivatives could be obtained from either of 
these fractions, but both gave the usual colour reactions 
for sesquiterpenes met with in this type of oil. It will no 
doubt be found to be identical with eudesmene. 
The portion boiling above 140° C. at 10 mm. having a 
specific gravity at t3° C. of 0°9606, optical rotation +12°4,
