A blister placed behind the ear, or burning the lap of the ear with a cloth dipped in boiling water, will often remove the pain entirely. TO PREVENT THE TOOTH-ACHE. Rub well the teeth and gums with a hard tooth-brush, using the flowers of sulphur as a tooth powder, every night on going to bed; and if it is done after dinner it will be best: this is an excellent preservative to the teeth, and void of any unpleasant smell. A RADICAL CURE FOR THE TOOTH-ACHE. Use as a tooth powder the Spanish snuff called Sabella, and it will clean the teeth as well as any other powder, and totally prevent the tooth-ache; and make a regular practice of washing behind the ears with cold water every morning; the remedy is infallible. REMEDY FOR BAD BREATH. Take from five to ten drops of muriatic acid, in an ale glassful of barley-water, and add a little lemon juice and lemon peel to flavour. Mix for a draught, to be taken three times a day, for a month or six weeks at least, and, if effectual, it may be continued occasionally. Another medicine of this kind, which has often proved beneficial when the stomach has been wrong, and the bowels costive, is, the DRAUGHT FOR BAD BREATH WITH COSTIVENESS. Take one dram of sulphate of magnesia, two drams of tincture of calumba, an ounce and a half of infusion of roses. Make a draught, to be taken every morning or every other morning, an hour before breakfast, for at least a month. PALMA CHRISTI OIL FOR THICKENING THE HAIR. Take an ounce of Palma Christi oil, a sufficient quantity of oil of bergamot or lavender to scent it. Apply it morning and evening for three months, or as long as it may be necessary, to the parts where you want the hair to grow thick and luxuriant. MACASSAR OIL. Take three quarts of common oil, half a pint of spirit of wine, three ounces of cinnamon powder, two ounces of bergamot. Put it in a large pipkin, and give it a good heat. When it is off the fire, add three or four pieces of alkanet root, and keep it closely covered for several hours. Filter it through a funnel lined with blotting paper. The commonest oil is used; and, when rancid, it is remedied by putting in two or three slices of an onion. EXCELLENT HAIR OIL. Boil half a pound of green southern wood, in a pint and a half of sweet oil, and half a pint of port wine. When sufficiently boiled, remove it from the fire, and strain the liquor through a linen bag. Repeat this operation three times, with fresh southern wood; and the last time add to the strained materials, two ounces of bear’s grease. It is excellent for promoting the growth of the hair, and preventing baldness. LYE FOR STRENGTHENING THE HAIR.
