VOLKAMERIA.—­An exquisite perfume is sold under this name, presumed, of course, to be derived from the Volkameria inermis (LINDLEY).  Whether it has a smell resembling the flower of that plant, or whether the plant blooms at all, we are unable to say.  It is a native of India, and seems to be little known even in the botanic gardens of this country; however, the plant has a name, and that’s enough for the versatile Parisian perfumer, and if the mixture he makes “takes” with the fashionable world—­the plant which christens it has a fine perfume for a certainty!

ESSENCE OF VOLKAMERIA.

Esprit de violette, 1 pint.
   " tubereuse, 1 "
   " jasmine, 1/4 "
   " rose, 1/2 "
Essence de muse, 2 oz.

WALLFLOWER (Cherianthus).—­Exquisite as is the odor of this flower, it is not used in perfumery, though no doubt it might be, and very successfully too, were the plant cultivated for that purpose.  To this flower we would direct particular attention, as one well adapted for experiments to obtain its odoriferous principle in this country, our climate being good for its production.  The mode for obtaining its odor has been indicated when we spoke of heliotrope, page 60.  And if it answers on the small scale, there is little doubt of success in the large way, and there is no fear but that the scent of the old English wallflower will meet with a demand.

An IMITATION ESSENCE OF WALLFLOWER can be compounded thus:—­

Extract fleur d’orange, 1 pint.
  " vanilla, 1/2 "
Esprit de rose, 1 "
Extract of orris, 1/2 "
  " cassie, 1/2 "
Essential oil of almonds, 5 drops.

Allow this mixture to be made up for two or three weeks prior to putting it up for sale.

WINTER GREEN (Trientalis Europoea).—­A perfuming otto can be procured by distilling the leaves of this plant:  it is principally consumed in the perfuming of soaps.  Upon the strength of the name of this odorous plant a very nice handkerchief perfume is made.

We have now described all the important odoriferous bodies which are used by the manufacturing perfumer, as derived from the botanic kingdom; it may be understood that where an odoriferous material is unnoticed, it has no qualities peculiar enough to be remarked on, and that the methods adopted for preparing its essence, extract, water, or oil, are analogous to those that have been already noticed, that is, by the processes of maceration, absorption, or enfleurage for flowers, by tincturation for roots, and by distillation for seeds, modified under certain circumstances.
