We hope that those of our readers who feel inclined to try experiments of this nature will not be deterred by saying, “they are not worth the trouble.”  It must be remembered, that very fine essences realize in the London perfumery warehouses 16_s._ per pint of 16 ounces, and that fine flowery-scented pomades fetch the same sum per pound.  If the experiments are successful they should be published, as then we may hope to establish a new and important manufacture in this country.  But we are digressing.

The odor of heliotrope resembles a mixture of almonds and vanilla, and is well imitated thus:—­

EXTRACT OF HELIOTROPE.

Spirituous extract of vanilla, 1/2 pint.
     " " French rose pomatum, 1/4 "
     " " orange-flower pomatum, 2 oz.
     " " ambergris, 1 oz. 
Essential oil of almonds, 5 drops.

A preparation made in this manner under the name of Extract de Heliotrope is that which is sold in the shops of Paris and London, and is really a very nice perfume, passing well with the public for a genuine extract of heliotrope.

HONEYSUCKLE or WOODBINE:—­

    “Copious of flower the woodbine, pale and wan,
    But well compensating her sickly looks
    With never-cloying odors.”

What the poet Cowper here says is quite true; nevertheless, it is a flower that is not used in practical perfumery, though there is no reason for abandoning it.  The experiments suggested for obtaining the odor of Heliotrope and Millefleur (thousand flowers) are also applicable to this, as also to Hawthorn.  A good IMITATION OF HONEYSUCKLE is made thus:—­

Spirituous extract of rose pomatum, 1 pint.
              " " violet " 1 "
              " " tubereuse " 1 "
Extract of vanilla, 1/4 "
       " Tolu, 1/4 "
Otto neroli, 10 drops.
   " almonds, 5 "

The prime cost of a perfume made in this manner would probably be too high to meet the demand of a retail druggist; in such cases it may be diluted with rectified spirit to the extent “to make it pay,” and will yet be a nice perfume.  The formula generally given herein for odors is in anticipation that when bottled they will retail for at least eighteen-pence the fluid ounce! which is the average price put on the finest perfumery by the manufacturers of London and Paris.

HOVENIA.—­A perfume under this name is sold to a limited extent, but if it did not smell better than the plant Hovenia dulcis or H. inequalis, a native of Japan, it would not sell at all.  The article in the market is made thus:—­

Rectified spirit, 1 quart. 
Rose-water, 1/2 pint. 
Otto lemons, 1/2 oz. 
Otto of rose, 1 drachm.
      " cloves, 1/2 "
      " neroli, 10 drops.
