FROSTBITES are frequently so sudden that one is not aware when they occur. In Canada it is not uncommon for persons meeting in the street to say, "Mind, sir, your nose looks whitish." The blood cools and runs slowly, and the blood vessels become choked and swollen. _Keep from the heat_. Rub the part quickly with snow, if necessary for hours, till the natural color is restored. If one is benumbed with cold, take him into a cold room, remove the wet clothes, rub the body dry, cover with blankets, and give a little warm tea or other suitable drink. On recovering, let him be brought to a fire gradually. [Footnote: If you are caught in a snowstorm, look for a snow bank in the lee of a hill, or a wood out of the wind, or a hollow in the plain filled with snow. Scrape out a hole big enough to creep into, and the drifting snow will keep you warm. Men and animals have been preserved after days of such imprisonment. Remember that if you give way to sleep in the open field, you will never awake.] FEVERS, and many acute diseases, are often preceded by a loss of appetite, headache, shivering, "pains in the bones," indisposition to work, etc. In such cases, sponge with tepid water, and rub the body till all aglow. Go to bed, place hot bricks to the feet, take nothing but a little gruel or beef tea, and drink moderately of warm, cream-of-tartar water. If you do not feel better the next morning, call a physician. If that be impossible, take a dose of castor oil or Epsom salts. SUNSTROKE is a sudden prostration caused by intense heat. The same effect is produced by the burning rays of the sun and the fierce fire of a furnace. When a person falls under such circumstance, place your hand on his chest. If the skin be cool and moist, it is not a sunstroke; but if it be dry and "biting hot," there can be no mistake. Time is now precious. At once carry the sufferer to the nearest pump or hydrant, and dash cold water on the head and chest until consciousness is restored.--DR. H. C. WOOD. To prevent sunstroke, wear a porous hat, and in the top of it place a wet handkerchief; also drink freely of water, not ice cold, to induce abundant perspiration. ASPHYXIA, or apparent death, whether produced by drowning, suffocation, bad air, or coal gas, requires very similar treatment. Send immediately for blankets, dry clothing, and a physician. Treat upon the spot, if the weather be not too unfavorable. 1. Loosen the clothing about the neck and chest, separate the jaws, and place between them a cork or bit of wood. 2. Turn the patient on his face, place his arm under his forehead to raise the head, and press heavily with both hands upon the ribs to squeeze out the water.
