Essences, Flower

Those for which separate formulæ are not given in this work may most of them be made from the e ential oil of the flowers and rectified spirit, as the last; or by digesting the flowers (crushed or bruised), 3 to 5 lbs., in proof spirit, 2 galls., for a few days, and then drawing over, by distillation, 1 gall. For the e ences of those flowers which are not strongly odorous, the spirit thus obtained is distilled from a like quantity of flowers, a second, and a third time, or even oftener. The e ences of other organic substances, whose fragrant principles are volatile, may be prepared in the same manner. A small quantity of some other odorous e ence is frequently added to the product, to enrich or modify the fragrance. See Flowers and E ences by Infusion .
