Extract of Vanilla is also used largely in the manufacture of
hair-washes, which are readily made by mixing the extract of vanilla
with either rose, orange, elder, or rosemary water, and afterwards
filtering.

We need scarcely mention, that vanilla is greatly used by cooks and
confectioners for flavoring.

VERBENA, or VERVAINE.--The scented species of this
plant, the lemon verbena, _Aloysia citriodora_ (Hooker), gives one of
the finest perfumes with which we are acquainted; it is well known as
yielding a delightful fragrance by merely drawing the hand over the
plant; some of the little vessels or sacks containing the otto must be
crushed in this act, as there is little or no odor by merely smelling at
the plant.

The otto, which can be extracted from the leaves by distillation with
water, on account of its high price, is scarcely, if ever, used by the
manufacturing perfumer, but it is most successfully imitated by mixing
the otto of lemon grass, _Andropogon schoenanthus_, with rectified
spirit, the odor of which resembles the former to a nicety. The
following is a good form for making the
