(or essential oil) or. In the Encyclopedia, under the word Roses, we have given one receipt for making this very high-priced perfume; and we shall here give another; which, whether it be as effectual or not, is at least simpler and less expensive. It is by an officer who was in the country where the Otter is prepared, and who assisted in making it himself; and is as follows:
"Take a very large glazed earthen or stone jar, or a large clean wooden cask; fill it with the leaves of the flowers of roses, very well picked, and freed from all seeds and stalks; pour on them as much pure spring water as will cover them, and set the vessel in the sun, in the morning at sunrise, and let it stand till the evening, then take it into the house for the night; expose it, in this manner, for five or seven successive days, and, at the end of the third or fourth day, a number of particles, of a fine yellow oily matter, will float on the surface, which, in two or three days more, will gather into a scum, which is the otter of roses. This is taken up by some cotton, tied to the end of a piece of stick, and squeezed with the finger and thumb into a small phial, which is immediately well stoppered; and this is repeated for some successive evenings, or while any of this fine essential oil rises to the surface of the water."
Dr Donald Mouro, who communicated this receipt to the Royal Society of Edinburgh, says, that he has been informed, that some few drops of this essential oil have more than once been collected by distillation in London, in the same manner as the essential oils of other plants.
