LEMON GRASS.--According to Pereira, the otto in the market under this name is derived from the _Andropogon schoenanthus_ a species of grass which grows abundantly in India. It is cultivated to a large extent in Ceylon and in the Moluccas purposely for the otto, which from the plant is easily procured by distillation. Lemon grass otto, or, as it is sometimes called, oil of verbena, on account of its similarity of odor to that favorite plant, is imported into this country in old English porter and stout bottles. It is very powerful, well adapted for perfuming soaps and greases, but its principal consumption is in the manufacture of artificial essence of verbena. From its comparatively low price, great strength, and fine perfume (when diluted), the lemon grass otto may be much more used than at present, with considerable advantage to the retail shopkeeper. LILAC.--The fragrance of the flowers of this ornamental shrub is well known. The essence of lilac is obtained either by the process of maceration, or enfleurage with grease, and afterwards treating the pomatum thus formed with rectified spirit, in the same manner as previously described for cassie; the odor so much resembles tubereuse, as to be frequently used to adulterate the latter, the demand for tubereuse being at all times greater than the supply. A beautiful IMITATION OF ESSENCE OF WHITE LILAC may be compounded thus:-- Spirituous extract from tubereuse pomade, 1 pint. " of orange-flower pomade, 1/4 " Otto of almonds, 3 drops. Extract of civet, 1/2 oz. The civet is only used to give permanence to the perfume of the handkerchief. LILY.--The manufacturing perfumer rejects the advice of the inspired writer, to "consider the lilies of the field." Rich as they are in odor, they are not cultivated for their perfume. If lilies are thrown into oil of sweet almonds, or ben oil, they impart to it their sweet smell; but to obtain anything like fragrance, the infusion must be repeated a dozen times with the same oil, using fresh flowers for each infusion, after standing a day or so. The oil being shaken with an equal quantity of spirit for a week, gives up its odor to the alcohol, and thus extract of lilies _may_ be made. But how it _is_ made is thus:-- IMITATION "LILY OF THE VALLEY." Extract of tubereuse, 1/2 pint. " jasmine, 1 oz. " fleur d'orange, 2 oz. " vanilla, 3 oz. " cassie, 1/4 pint. " rose, 1/4 " Otto of almonds, 3 drops. Keep this mixture together for a month, and then bottle it for sale. It is a perfume that is very much admired. MACE.--Ground mace is used in the manufacture of some of those scented powders called Sachets. A strong-smelling essential oil may be procured from it by distillation, but it is rarely used.
