Fractions IV and V . — These two fi-actions were combined and boiled 
with a solution of potassium hydroxide in alcohol to hydrolyse any 
esters present. The oil recovered from this treatment was distilled at 
100mm. when two main fractions were obtained boiling at 110 — -140° 
and 160 — 185°. The first of these fractions was found to contain 
terpinene (identified by the nitrosite), whilst the second fraction which 
smelt strongly of terpineol contained a small quantity of an alcohol 
which was not identified. 
Free Acids. 
Ihe sodium carbonate extract of the original oil was washed with 
ether to remove adhering oil and acidified when a liquid acid separat- 
ed which rapidly solidified. The solid was collected, drained on porous 
porcelain, and recrystallised from methyl alcohol when it was obtained 
as leaflets which melted at 62-63° and was identified as palmitic acid.
