the flowers of Daphne odorata. It is most probable that these bodies
are mixtures of primary and secondary decatyl compounds.
Gaprio Acid 10 "U > 0 occurs in different fats and in fusel-oil.
It is a crystalline solid, fusing at 30°, boiling at 270°, and possessing
a faint, goat-like smelL
The so-called osnanthic eflier, which is found in different kinds of
wine, and which is the cause of the peculiar odour which all wines
have in common, contains ethyl caprate besides ethyl caprylnte, and
probably other compound ethers in varying quantities.
HENDECATYL GROUP.
Methyl-nonyl Carbinol Q JJ [ CH.OH.—This secondary alcohol
has been prepared by acting with sodium on an alcoholic solution
of methyl-nonyl ketone. It is a thick, colourless liquid, boiling at
229°. By acting on it with bromine and phosphorus the bromide
C^HjgBr is formed, which on distillation splits up into hydrobromic
acid and hendecatene CUH22, a liquid boiling at 200°.

CETYt GROUP.
Cetyl Alcohol 1B jjj-O.—Spermaceti consists principally of cetyl
pabnitate; on heating it with an alcoholic potash solution cetyl
alcohol is obtained, which forms small white crystals, melting at 50°
and volatilizing at a high temperature without decomposition. It is
insoluble in water, but readily soluble iu alcohol and ether. By
heating it with iodine and phosphorus, cetyl iodide is formed, a white
crystalline mass, melting at 22° and decomposing at a higher tempe-
rature. By acting with sodium on fused cetyl alcohol, sodium cetylate
