are covered either with the liquid ammonia,
scented as above, or with alcoholic ammonia. The necks of the bottles
are filled with a piece of white cotton; otherwise, when inverted, from
the non-absorbent quality of the crystals, the ammonia runs out, and
causes complaints to be made. The crystals are prettier in colored
bottles than the sponge; but in plain bottles the sponge appears quite
as handsome, and, as before observed, it holds the ammonia better than
any other material. Perfumers sell also what is called WHITE
SMELLING SALTS, and PRESTON SALTS. The White Smelling Salt
is the sesqui-carbonate of ammonia in powder, with which is mixed any
perfuming otto that is thought fit,--lavender otto giving, as a general
rule, the most satisfaction.
PRESTON SALTS, which is the cheapest of all the ammoniacal
compounds, is composed of some easily decomposable salt of ammonia and
lime, such as equal parts of muriate of ammonia, or of sesqui-carbonate
of ammonia, and of fresh-slaked lime. When the bottles are filled with
this compound, rammed in very hard, a drop or two of some cheap otto is
poured on the top prior to corking. For this purpose otto of French
lavender, or otto of bergamot, answers very well. We need scarcely
mention that the corks are dipped into melted sealing-wax, or brushed
over with liquid wax, that is, red or black wax dissolved in alcohol, to
which a small portion of ether is added. The only other compound of
ammonia that is sold in the perfumery trade is Eau de Luce, though
properly it belongs to the druggist. When correctly made--which is very
rarely the case--it retains the remarkable odor of oil of amber, which
renders it characteristic.

If requisite, strain through cotton wool, but it must not be filtered,

ACETIC ACID AND ITS USE IN PERFUMERY.--The pungency of the odor
of vinegar naturally brought it into the earliest use in the art of
perfumery.
The acetic acid, evolved by distilling acetate of copper (verdigris), is
the true "aromatic" vinegar of the old alchemists.
The modern aromatic vinegar is the concentrated acetic acid aromatized
with various ottos, camphor, &c., thus--
AROMATIC VINEGAR.
