=Obesity and Thinness.=--To increase the weight; Eat, to the extent of satisfying a natural appetite, of fat meats, butter, cream, milk, cocoa, chocolate, bread, potatoes, peas, parsnips, carrots, beets, farinaceous food, or Indian corn, rice, tapioca, sago, corn-starch, pastry, custards, oatmeal, sugar, sweet wines, and ale. Avoid acids. Exercise as little as possible, sleep all you can, and don't worry or fret. To reduce the weight: Eat, to the extent of satisfying a natural appetite, of lean meat, poultry, game, eggs, milk moderately, green vegetables, turnips, succulent fruits, tea or coffee. Drink lime juice, lemonade, and acid drinks. Avoid fat, butter, cream, sugar, pastry, rice, sago, tapioca, corn-starch, potatoes, carrots, beets, parsnips, and sweet wines. Exercise freely. =Piles.=--When piles become painful, whether they protrude or not, the patient should take a warm hip-bath and remain in until the pain ceases, extra precaution being taken for cleanliness, using pure white castile soap with the hip-bath. A careful diet of farinaceous and other easily-digested food, and regularity in going to stool, will suffice to cure the majority of cases. If the piles are bleeding, apply a salve of opium and nut-gall; if itching, a drop of oil of cade will give relief. Linseed oil, applied to the piles, is said to be an effective remedy. In severe cases of piles great relief is afforded by the use of suppositories made after the following formula: 2 grains sulphate morphina, 2 grains extract belladonna, 1 scruple tannin. The above mixed with a sufficient quantity of cocoa butter to make twelve suppositories of one-half ounce each; one to be used every night on retiring. =Poisons.=--Poisons may be classified under two distinct heads--_mineral_ and _vegetable_. _Mineral poisons_ are irritating and corrosive in their action. They produce a metallic taste in the mouth, burning pains in the throat, stomach, and bowels, and, often, violent retching and bloody vomiting, purging, cramps, cold sweats, and great depression. _Vegetable poisons_ are chiefly narcotics, and many of them are as virulent as any in the mineral kingdom. They cause giddiness, drowsiness, stupor, insensibility or delirium, and oppressed breathing.
