opalescenceApart from the strikingly low rotation, which would correspond with
that of cananga oil, the general constants of the four samples agree with
those which have thus far been recorded for ylang-ylang oil, but some of
the samples in question are very much more soluble, which shows that
they contain very little sesquiterpene. That would be an advantage
rather than otherwise, but notwithstanding this, samples 2, 3, and 4 were
quite useless for perfumery purposes because their aroma was wholly
insufficient, and steadily deteriorated according to the age of the raw
material used.
