3. (Aqua Orientalis.) From grain silver, 2 dr.; steel filings, 4 dr.; nitric acid, 1 oz.; soft water, 11⁄2 fl. oz.; digested together, the solution being afterwards diluted with water, 31⁄2 fl. oz., and filtered. Applied by means of a fine-toothed comb, or a half-worn tooth-brush to the hair, previously well cleaned with soap and water, and dried.
4. (Argentan tincture.) From nitrate of silver, 1 dr.; eau de rose, 1 fl. oz.; nitrate of copper, 2 gr., or q. s. to impart a slight greenish tint. Used as the last.
5. (Dr Cattell.) Nitrate of silver, 11 dr.; nitric acid, 1 dr.; distilled water, 1 pint; sap green, 3 dr.; gum arabic, 11⁄4 dr.; digest together. Used as No. 3.
6. No. 1 Solution. Gallic acid, 71⁄2 gr.; acetic acid, 20 min.; distilled water, 1 fl. oz.
No. 2 Solution. Nitrate of silver, in crystals, 301⁄2 gr.; distilled water, 1 fl. oz.; ammonia sufficient to form the precipitate formed at first.
7. (Chestnut hair dye.) “We have met with the following, but do not guarantee it:— Permanganate of potash gives the hair a beautiful chestnut-brown colour, varying according to the strength of the solution of the salt. A good formula is permanganate of potash, 1 dr.; powdered gum Arabic, 2 dr.; rose water, 3 oz.; mix. Apply carefully with a tooth brush so as to avoid staining the skin. (‘Chemist and Druggist.’)
8. (Hair restorer.) This is in reality a dye. Sulphur, 45 gr.; acetate of lead, 20 gr.; glycerin, 1⁄2 oz.; water to make up 10 oz.
9. (Golden hair dye, Aureoline.) A solution of peroxide of hydrogen in water; containing from 3 to 6 per cent. of the peroxide.
10. (Brown hair dye.) Acetate of lead, 2 dr.; hyposulphate of soda, 1 dr.; rose water, 14 oz.; glycerin, 2 oz. Dissolve the acetate of lead and the hyposulphite in separate portions of the rose water; filter separately, mix the solutions, and add the glycerin.
11. (A harmless hair dye. Dr Hager.) Ten parts of subnitrate of bismuth, and 150 parts of glycerin are mixed in a glass vessel and heated in a water bath; solution of potash is then added in small portions, and with continued agitation, until a clear solution has been obtained, to which a concentrated solution of citric acid is added until merely a slight alkaline reaction is observed. Enough orange-flower water is added to make the whole liquid weigh 300 parts; the addition of a small quantity of a solution of an aniline colour completes the preparation.
