470. _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 flavor; 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 following: Take one drachm of sulphate of magnesia, two drachms of tincture of calumba, one 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. 471. _Corpulence._--Those who are afflicted with corpulence should not allow themselves above six hours' sleep in the twenty-four. They should take as much exercise as possible, and avoid cream, malt liquors and soups--at least until they have succeeded in reducing their bulk. Salt provisions are good, having a tendency to promote perspiration, and carry off fat. Soda water is also beneficial. _Recipe_: Take Castile soap, in the form of pills, or electuary, of from one to four drachms dissolved in a quarter of a pint of soft water, when going to bed. But let not our lovely girls abuse their constitutions by drinking vinegar for this purpose, for consumption has often been produced by that habit. 472. _Leanness._--This is not a disease; on the contrary, lean people are generally healthy, muscular, strong, and active, and remarkable for a keen appetite. But when there appears a diminution of strength--when the spirits sink, and the food does not freely digest--then leanness is the sign of lurking disease. Such patients should take a cup of milk warm from the cow every morning, or cold milk, with two raw fresh eggs beaten up with it. A pint of the best porter or stout at dinner, and the same at supper. Tea is better than coffee, and salad with strong supplies of oil, not much vinegar, are recommended. 473. _Cure for Stammering._--Impediments in the speech may be cured, where there is no malformation of the organs of articulation, by perseverance for three or four months in the simple remedy of reading aloud, with the teeth closed, for at least two hours in the course of each day. POISONS AND ANTIDOTES. 474. _Acids._--These cause great heat, and sensation of burning pain, from the mouth down to the stomach. Remedies, magnesia, soda, pearlash, or soap, dissolved in water; then use stomach-pump or emetics. 475. _Alcohol._--First cleanse out the stomach by an emetic, then dash cold water on the head, and give ammonia (spirits of hartshorn.) 476. _Alkalies._--Best remedy is vinegar. 477. _Ammonia._--Remedy, lemon-juice or vinegar, afterwards milk and water or flaxseed tea. 478. _Arsenic._--Remedies, in the first place evacuate the stomach, then give the white of eggs, lime-water, or chalk and water, charcoal and the preparations of iron, particularly hydrate.
