Tuberose.—One of the most exquisite odors with which we are acquainted is obtained by enfleurage from the tuberose flower. It is, as it were, a nosegay in itself, and reminds one of that delightful perfume observed in a well-stocked flower-garden at evening close; consequently it is much in demand by the perfumers for compounding sweet essences.
Extract of Tuberose.
This essence of tuberose, like that of jasmine, is exceedingly volatile, and if sold in its pure state quickly "flies off" the handkerchief; it is therefore necessary to add some fixing ingredient, and for this purpose it is best to use one ounce of extract of orris, or half an ounce of extract of vanilla, to every pint of tuberose.
Vanilla.—The pod or bean of the Vanilla planifolia yields a perfume of rare excellence. When good, and if kept for some time, it becomes covered with an efflorescence of needle crystals possessing properties similar to benzoic acid, but differing from it in composition. Few objects are more beautiful to look upon than this, when viewed by a microscope with the aid of polarized light.
Vanilla.
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 schœnanthus, with rectified spirit, the odor of which resembles the former to a nicety. The following is a good form for making the
Another mixture of this kind, presumed by the public to be made from the same plant, but of a finer quality, is composed thus—it is sold under the title
Violet.—
Real violet is, however, sold by many of the retail perfumers of the West End of London, but at a price that prohibits its use except by the affluent or extravagant votaries of fashion. The violet farms from whence the flowers are procured to make this perfume are very extensive at Nice and Grasse, also in the neighborhood of Florence. The true smelling principle or otto of violets has never yet been isolated: a very concentrated solution in alcohol impresses the olfactory nerve with the idea of the presence of hydrocyanic acid, which is probably a true impression. Burnett says that the plant Viola tricolor (heart's ease), when bruised, smells like peach kernels, and doubtless, therefore, contains prussic acid.
The flowers of the heart's ease are scentless, but the plant evidently contains a principle which in other species of the Viola, is eliminated as the "sweet that smells" so beautifully alluded to by Shakspeare.
For commercial purposes, the odor of the violet is procured in combination with spirit, oil, or suet, precisely according to the methods previously described for obtaining the aroma of some other flowers before mentioned, such as those for cassie, jasmine, orange-flower, namely, by maceration, or by enfleurage, the former method being principally adopted, followed by, when "essence" is required, digesting the pomade in rectified alcohol.
Good essence of violets, thus made, is of a beautiful green color, and, though of a rich deep tint, has no power to stain a white fabric, and its odor is perfectly natural.
The essence of violet, as prepared for retail sale, is thus made, according to the quality and strength of the pomade:—Take from six to eight pounds of the violet pomade, chop it up fine, and place it into one gallon of perfectly clean (free from fusel oil) rectified spirit, allow it to digest for three weeks or a month, then strain off the essence, and to every pint thereof add three ounces of tincture of orris root, and three ounces of esprit de cassie; it is then fit for sale.
We have often seen displayed for sale in druggists' shops plain tincture of orris root, done up in nice bottles, with labels upon them inferring the contents to be "Extract of Violet;" customers thus once "taken in" are not likely to be so a second time.
About four pounds of the dried vitivert, as it is imported, being cut small and set to steep in a gallon of rectified spirits for a fortnight, produces the
Essence of Vitivert of the shops. In this state it is rarely used as a perfume, although it is occasionally asked for by those who, perhaps, have learnt to admire its odor by their previous residence in "the Eastern clime." The extract, essence, or tincture of vitivert, enters into the composition of several of the much-admired and old bouquets manufactured in the early days of perfumery in England, such as "Mousselaine des Indies," for which preparation M. Delcroix, in the zenith of his fame, created quite a furor in the fashionable world.
Vitivert.
Essence of vitivert is also made by dissolving 2 oz. of otto of vitivert in 1 gallon of spirit; this preparation is stronger than the tincture, as above.
Marechale and Bouquet du Roi, perfumes which have also "had their day," owe much of their peculiarity to the vitivert contained in them.
Bundles of vitivert are sold for perfuming linen and preventing moth, and, when ground, is used to manufacture certain sachet powders.
Otto of vitivert is procurable by distillation; a hundred-weight of vitivert yields about 14 oz. of otto, which in appearance very much resembles otto of santal. I have placed a sample of it in the museum at Kew.
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!
" rose, 1/2 "
An Imitation Essence of Wallflower can be compounded thus:—Extract fleur d'orange, 1 pint.
Allow this mixture to be made up for two or three weeks prior to putting it up for sale.
Winter Green (Trientalis Europœa).—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.
There are, however, three other important derivative odors—ambergris, civet, and musk—which, being from the animal kingdom, are treated separately from plant odors, in order, it is considered, to render the whole matter less confused to manufacturers who may refer to them. Ammonia and acetic acid, holding an indefinite position in the order we have laid down, may also come in here without much criticism, being considered as primitive odors.
On terminating our remarks relating to the simple preparations of the odors of plants, and before we speak of perfumes of an animal origin, or of those compound odors sold as bouquets, nosegays, &c., it may probably be interesting to give a few facts and statistics, showing the consumption, in England, of the several substances previously named.
There were also passed through the Custom House for home consumption, in 1852—
Pomatums, procured by enfleurage, maceration, &c., commonly called "French Pomatums,"
average value of 6s.per pound, and paying a duty of 1s.per pound, valued by the importers at £1,306
Perfumery not otherwise described; value £1,920
Number of bottles of eau de Cologne, paying a duty of 1s. each, 19,777
Revenue from eau de Cologne manufactured out of England, say 20,000 flacons at 8d. = 8,000l. annually.
The total revenue derived from various sources, even upon this low scale of duties, from the substances with which "Britannia perfumes her pocket handkerchief," cannot be estimated at less than 40,000l. per annum. This, of course, includes the duty upon the spirits used in the home manufacture of perfumery.
SECTION IV.
PERFUMES OF ANIMAL ORIGIN.
In the previous articles we have only spoken of the odors of plants; we now enter upon those materials used in perfumery of an animal origin. The first under our notice is—
Ambergris.—This substance is found in the sea, floating near the islands of Sumatra, Molucca, and Madagascar; also on the coasts of America, Brazil, China, Japan, and the Coromandel. The western coast of Ireland is often found to yield large pieces of this substance. The shores of the counties of Sligo, Mayo, Kerry, and the isles of Arran, are the principal places where it has been found. In the "Philosophical Transactions" there is an account of a lump found on the beach of the first-mentioned county, in the year 1691, which weighed 52 oz., and was bought on the spot for 20l., but which afterwards was sold in London for more than 100l. (Philos. Trans. No. 227, p. 509). We are quite within limit in stating that many volumes concerning the origin of ambergris have been written, but the question respecting it is still at issue. It is found in the stomachs of the most voracious fishes, these animals swallowing, at particular times, everything they happen to meet with. It has been particularly found in the intestines of the spermaceti whale, and most commonly in sickly fish, whence it is supposed to be the cause or effect of the disease.
Some authors, and among them Robert Boyle, consider it to be of vegetable production, and analogous to amber; hence its name amber-gris (gray) gray amber. It is not, however, within the province of this work to discuss upon the various theories about its production, which could probably be satisfactorily explained if our modern appliances were brought to bear upon the subject. The field is open to any scientific enthusiast; all recent authors who mention it, merely quoting the facts known more than a century ago.
A modern compiler, speaking of ambergris, says, "It smells like dried cow-dung." Never having smelled this latter substance, we cannot say whether the simile be correct; but we certainly consider that its perfume is most incredibly overrated; nor can we forget that Homberg found that "a vessel in which he had made a long digestion of the human fæces had acquired a very strong and perfect smell of ambergris, insomuch that any one would have thought that a great quantity of essence of ambergris had been made in it. The perfume (odor!) was so strong that the vessel was obliged to be moved out of the laboratory." (Mem. Acad. Paris, 1711.)
Nevertheless, as ambergris is extensively used as a perfume, in deference to those who admire its odor, we presume that it has to many an agreeable smell.
Like bodies of this kind undergoing a slow decomposition and possessing little volatility, it, when mixed with other very fleeting scents, gives permanence to them on the handkerchief, and for this quality the perfumer esteems it much.
Essence of Ambergris
Is only kept for mixing; when retailed it has to be sweetened up to the public nose; it is then called after the Parisian name
Extrait d'Ambre.
This perfume has such a lasting odor, that a handkerchief being well perfumed with it, will still retain an odor even after it has been washed.
The fact is, that both musk and ambergris contain a substance which clings pertinaciously to woven fabrics, and not being soluble in weak alkaline lyes, is still found upon the material after passing through the lavatory ordeal.
Powdered ambergris is used in the manufacture of cassolettes—little ivory or bone boxes perforated—which are made to contain a paste of strong-smelling substances, to carry in the pocket or reticule; also in the making of peau d'Espagne, or Spanish skin, used for perfuming writing paper and envelopes, and which will be described hereafter.
Civet Cat.
Civet.—This substance is secreted by the Viverra civetta, or civet cat. It is formed in a large double glandular receptacle between the anus and the pudendum of the creature. Like many other substances of Oriental origin, it was first brought to this country by the Dutch.
When the civet cats are kept in a state of confinement, which at one time was common in Amsterdam, they are placed in strong cages, so constructed as to prevent the animal from turning round and biting the person employed in collecting the secreted substance. This operation is said to be performed twice a week, and is done by scraping out the civet with a small spoon: about a drachm at a time is thus obtained. A good deal of the civet now brought to European markets is from Calicut, capital of the province of Malabar, and from Bassora on the Euphrates.
In its pure state, civet has, to nearly all persons, a most disgusting odor; but when diluted to an infinitesimal portion, its perfume is agreeable. It is difficult to ascertain the reason why the same substance, modified only by the quantity of matter presented to the nose, should produce an opposite effect on the olfactory nerve; but such is the case with nearly all odorous bodies, especially with ottos, which, if smelled at, are far from nice, and in some cases, positively nasty—such as otto of neroli, otto of thyme, otto of patchouly; but if diluted with a thousand times its volume of oil, spirit, &c., then their fragrance is delightful.
Otto of rose to many has a sickly odor, but when eliminated in the homeopathic quantities as it rises from a single rose-bloom, who is it that will not admit that "the rose is sweet?" The odor of civet is best imparted, not by actual contact, but by being placed in the neighborhood of absorbent materials. Thus, when spread upon leather, which, being covered with silk and placed in a writing-desk, perfumes the paper and envelopes delightfully, and so much so, that they retain the odor after passing through the post.
Extract of Civet is prepared by rubbing in a mortar one ounce of civet with an ounce of orris-root powder, or any other similar material that will assist to break up or divide the civet; and then placing the whole into a gallon of rectified spirits; after macerating for a month, it is fit to strain off. It is principally used as a "fixing" ingredient, in mixing essences of delicate odor. The French perfumers use the extract of civet more than English manufacturers, who seem to prefer extract of musk. From a quarter of a pint to half a pint is the utmost that ought to be mixed with a gallon of any other perfume.
Castor is a secretion of the Castor fiber, or beaver, very similar to civet. Though we have often heard of its being used in perfumery, we do not personally know that such is the case.
Musk.—This extraordinary substance, like civet, is an animal secretion; it is contained in excretory follicles about the navel of the male animal. In the perfumery trade these little bags are called "pods," and as imported it is called "pod musk." When the musk is separated from the skin or sack in which it is contained, it is then called "grain musk."
The musk deer (Moschus moschatus) is an inhabitant of the great mountain range which belts the north of India, and branches out into Siberia, Thibet, and China. And it is also found in the Altaic range, near Lake Baikal, and in some other mountain ranges, but always on the borders of the line of perpetual snow. It is from the male animal only that the musk is produced.
Musk Pod, actual size.
It formerly was held in high repute as a medicine, and is still so among Eastern nations. The musk from Boutan, Tonquin, and Thibet, is most esteemed, that from Bengal is inferior, and from Russia is of still lower quality. The strength and the quantity produced by a single animal varies with the season of the year and the age of the animal. A single musk pod usually contains from two to three drachms of grain musk. Musk is imported into England from China, in caddies of from 50 to 100 ounces each. When adulterated with the animal's blood, which is often the case, it forms into lumps or clots; it is sometimes also mixed with a dark, friable earth. Those pods in which little pieces of lead are discovered, as a general rule, yield the finest quality of musk; upon this rule, we presume that the best musk is the most worthy of adulteration. Musk is remarkable for the diffusiveness and subtlety of its scent; everything in its vicinity soon becomes affected by it, and long retains its odor, although not in actual contact with it.
It is a fashion of the present day for people to say "that they do not like musk;" but, nevertheless, from great experience in one of the largest manufacturing perfumatories in Europe, we are of opinion that the public taste for musk is as great as any perfumer desires. Those substances containing it always take the preference in ready sale—so long as the vendor takes care to assure his customer "that there is no musk in it."
The Musk Deer.
The perfumer uses musk principally in the scenting of soap, sachet powder, and in mixing for liquid perfumery. The just reputation of Paris's original Windsor soap is due, in the main, to its delightful odor. The soap is, doubtless, of the finest quality, but its perfume stamps it among the élite—its fragrance it owes to musk.
The alkaline reaction of soap is favorable to the development of the odoriferous principle of musk. If, however, a strong solution of potass be poured on to grain musk, ammonia is developed instead of the true musk smell.
