NUTMEG.--The beautiful odor of the nutmeg is familiar to all.
Though an otto can be drawn from them of a very fragrant character, it
is rarely used in perfumery. The ground nuts are, however, used
advantageously in the combinations of scented powders used for scent
bags.--See "Sachet's Powders."

OLIBANUM is a gum resin, used to a limited extent in this
country, in the manufacture of incense and pastilles. It is chiefly
interesting as being one of those odoriferous bodies of which frequent
mention is made in the Holy volume.[C]

"It is believed," says Burnett, "to have been one of the ingredients in
the sweet incense of the Jews; and it is still burnt as incense in the
Greek and Romish churches, where the diffusion of such odors round the
altar forms a part of the prescribed religious service."

Olibanum is partially soluble in alcohol, and, like most of the balsams,
probably owes its perfume to a peculiar odoriferous body, associated
with the benzoic acid it contains.

For making the tincture or extract of olibanum, take 1 pound of the gum
to 1 gallon of the spirit.

ORANGE.--Under the title "Neroli" we have already spoken of the
odoriferous principle of the orange-blossom. We have now to speak of
what is known in the market as Essence of Orange, or, as it is more
frequently termed, Essence of Portugal,--a name, however, which we
cannot admit in a classified list of the "odors of plants."
