Take of fresh lime-stone, 1 oz. pure potass, 1 drachm, sulphuret of potass, 1 drachm. Reduce them to a fine powder in a Wedgewood mortar. If the hair be first washed, or soaked in warm water, (130 Fahr.) for ten minutes, this article, formed into a thin paste with warm water, and applied whilst warm, will so effectually destroy the hair in five or six minutes, that it may be removed by washing the skin with flannel. It is a powerful caustic, and should therefore be removed as soon as it begins to inflame the skin, by washing it off with vinegar. It softens the skin, and greatly improves its appearance. 323. SPANISH LADIES’ ROUGE. Take good new scarlet wool cuttings, and spirit of wine, or lemon-juice, boil them in a well-glazed earthen pot, well stopped, till the liquid has charged itself with all the colour of the scarlet, strain the dye through a cloth, and all the colour therefrom; boil it afterwards in a little arabic water, till the colour becomes very deep. The proportion of materials is, to half a pound of scarlet cuttings, a quarter of a pint of spirit of wine, and a sufficient quantity of water to assist the soaking. Then, in the colour extracted, put a piece of gum arabic, of the size of a filbert: next steep some cotton in the colour, and wet some sheets of paper with the dye, which repeat several times, as often as they are dry, and you will find them sufficiently charged with rouge for use. 324. SPANISH VERMILION FOR THE TOILETTE. Pour into the alkaline liquor which holds in solution the colouring part of bastard saffron, such a quantity of lemon juice as may be necessary to saturate the whole alkaline salts. At the time of the precipitation, the latter appears under the form of a fecula full of threads, which soon falls to the bottom of the vessel. Mix this part with white talc, reduced to fine powder, and moistened with a little lemon-juice and water. Then form the whole into a paste, and having put it in small pots, expose it to dry. This colour is reserved for the use of the toilette; but it has not the durability of that prepared from cochineal. 325. ECONOMICAL ROUGE.
