Rose-water, 1 pint. Expressed juice of dandelion root, 1 oz. Esprit tubereuse, 8 oz. Green oil, wax, } Curd soap, } each 1/2 oz. Let the juice of the dandelion be perfectly fresh pressed; as it is in itself an emulsion, it may be put into the mortar after the almonds are broken up, and stirred with the water and spirit in the usual manner. MILK OF CUCUMBER. Sweet almonds, 4 oz. Expressed juice of cucumbers, 1 pint. Spirit (60 o.p.), 8 oz. Essence of cucumbers, 1/4 pint. Green oil, wax, } Curd soap, } each 1/2 oz.

ESSENCE OF CUCUMBERS. Break up in a mortar 28 lbs. of good fresh cucumbers; with the pulp produced mix 2 pints rectified spirit (sp. gr. .837), and allow the mixture to stand for a day and night; then distil the whole, and draw off a pint and a half. The distillation may be continued so as to obtain another pint fit for ulterior purposes. CREME DE PISTACHE. (_Milk of Pistachio Nuts_.) Pistachio nuts, 3 oz. Orange-flower water, 3-1/4 pints.
