MAGNOLIA.--The perfume of this flower is superb; practically, however, it is of little use to the manufacturer, the large size of the blossoms and their comparative scarcity prevents their being used, but a very excellent imitation of its odor is made as under, and is that which is found in the perfumers' shops of London and Paris. IMITATION "ESSENCE OF MAGNOLIA." Spirituous extract of orange-flower pomatum, 1 pint. " " rose pomatum, 2 pints. " " tubereuse pomatum, 1/2 pint. " " violet pomatum, 1/2 " Essential oil of citron, 3 drs. " " almonds, 10 drops. MARJORAM.--The otto procured by distilling _Origanum majorana_, commonly called oil of oringeat by the French, is exceedingly powerful, and in this respect resembles all the ottos from the different species of thyme, of which the marjoram is one. One hundred weight of the dry herb yields about ten ounces of the otto. Oringeat oil is extensively used for perfuming soap, but more in France than in England. It is the chief ingredient used by Gelle Freres, of Paris, for scenting their "Tablet Monstre Soap," so common in the London shops. MEADOW SWEET.--A sweet-smelling otto can be produced by distilling the _Spiraea ulmaria_, but it is not used by perfumers. MELISSA. See BALM. MIGNONETTE.--But for the exquisite odor of this little flower, it would scarcely be known otherwise than as a weed. Sweet as it is in its natural state, and prolific in odor, we are not able to maintain its characteristic smell as an essence. Like many others, during separation from the plant, the fragrance is more or less modified; though not perfect, it still reminds the sense of the odor of the flowers. To give it that sweetness which it appears to want, a certain quantity of violet is added to bring it up to the market odor. As this plant is so very prolific in odor, we think something might be done with it in England, especially as it flourishes as well in this country as in France; and we desire to see Flower Farms and organized Perfumatories established in the British Isles, for the extraction of essences and the manufacture of pomade and oils, of such flowers as are indigenous, or that thrive in the open fields of our country. Besides opening up a new field of enterprise and good investment for capital, it would give healthy employment to many women and children. Open air employment for the young is of no little consideration to maintain the stamina of the future generation; for it cannot be denied that our factory system and confined cities are prejudicial to the physical condition of the human family.
