[If the word _flavor_ had been used by the various authors who have
written upon this subject, in place of the word _perfume_, the
dissemination of an erroneous idea would have been prevented: the word
perfume, applied to pear-oil, pine-apple oil, &c., implies, and the
general tenor of the remarks of the writers leads the reader to infer,
that these substances are used by perfumers, who not only do not, but
cannot use them in their trade.

But for _flavoring_ nectar, lozenges, sweetmeats, &c., these ethers, or
oils as the writers term them, are extensively used, and quite in
accordance with assertions of Hoffman, Playfair, Fehling, and Bastick.
However, the glorious achievements of modern chemistry have not lost
anything by this misapplication of a trade term.--SEPTIMUS
PIESSE.]
