odoriferous bodies as "essential" or "volatile" oils, and of the greasy
bodies as "fat" or "unctuous" oils. Oils, properly so called, unite with
salifiable bases and form soap; whereas the essential or volatile oils,
_i.e._ what we would please to call the ottos, do no such thing. On the
contrary, they unite with acids in the majority of instances.

The word oil must hereafter be confined to those bodies to which its
literal meaning refers--fat, unctuous, inodorous (when pure), greasy
substances--and can no longer be applied to those odoriferous materials
which possess qualities diametrically opposite to oil. We have grappled
with "spirit," and fixed its meaning in a chemical sense; we have no
longer "spirit" of salt, or "spirit" of hartshorn. Let us no longer have
almond oil "essential," almond oil "unctuous," and the like.

It remains only for us to complete the branch of perfumery which relates
to odors for the handkerchief, by giving the formulæ for preparing the
most favorite "bouquets" and "nosegays." These, as before stated, are
but mixtures of the simple ottos in spirit, which, properly blended,
produce an agreeable and characteristic odor,--an effect upon the
smelling nerve similar to that which music or the mixture of harmonious
sounds produces upon the nerve of hearing, that of pleasure.
