thylurethane obtained from this (m.p.80°) when mixed with that 
prepared from the tea-oil caused no alteration of the melting point. 
The acid phthalic acid ester prepared from it, gave a silver salt- 
melting at 128°. By recrystallisation from alcohol the melting point 
could be raised to 134° (not sharp). With the silver salt prepared 
from the tea-alcohol it gave a mixture melting at 138°. 
The assumption is thus justified that the unsaturated alcohol 
prepared by me from the tea-oil is identical with the 8-y-hexenol, 
that is, with hexene-3-ol-6.
