Vinegar of squills is a very powerful stimulant; and hence it is frequently used with great success as a _diuretic and expectorant_. The dose of this medicine is from a dram to half an ounce. TAR-WATER. Take of tar, 2 pints; water, 1 gallon. Mix, by stirring them with a wooden rod for a quarter of an hour, and, after the tar has subsided, strain the liquor, and keep it in well corked phials. Tar-water should have the colour of white wine, and an empyreumatic taste. It is, in fact, a solution of empyreumatic oil, effected by means of acetous acid. It acts as a _stimulant raising the pulse_, and increasing the discharge by the skin and kidneys. It may be drank to the extent of a pint or two in the course of a day. DECOCTION OF SARSAPARILLA. Take of sarsaparilla root, cut, 6 oz. distilled water, 8 pints. After macerating for two hours, with a heat about 195 degrees, then take out the root, and bruise it; add it again to the liquor, and macerate it for two hours longer; then boil down the liquor to 4 pints, and strain it. The dose is from 4 oz. to half a pint, or more, daily. COMPOUND DECOCTION OF SARSAPARILLA. Take of sarsaparilla root, cut and bruised, 6 oz. the bark of sassafras root, the shavings of guaiacum wood, liquorice root, each 1 oz. the bark of mezereon root, 3 drams, distilled water, 10 pints. Digest with a gentle heat for six hours, then boil down the liquor to one half (or 5 pints) adding the bark of the mezereon root towards the end of boiling. Strain off the liquor. The dose is the same as the last, and for the same purposes. DECOCTION OF THE WOODS. Take of guaiacum raspings, 3 oz. raisins, stoned, 2 oz. sassafras root, sliced, liquorice root, bruised, each 1 oz. water, 10 lbs. Boil the guaiacum and raisins with the water, over a gentle fire, to the consumption of one half, adding, towards the end, the sassafras and liquorice, and strain the decoction without expression. INFUSION OF ROSES. Take of dried red roses, ½ oz. diluted vitriolic acid, 3 drams, boiling distilled water, 2½ pints, double refined sugar, 1½ oz. First pour the water on the petals, in a close vessel, then add the diluted vitriolic acid, and macerate for half an hour. Strain the liquor when cold, and add the sugar. EMETIC DRAUGHT. Take of ipecacuan wine, 7 drams, antimonial wine, 1 do. syrup of violets, 1 do. rose-water, 3 do. Make into a draught to be taken at eight in the evening; or, for an infant, give a tea-spoonful every five minutes until it operates, and half of it for a child of ten or twelve years.
