HOW TO TREAT SUNSTROKE. Should you ever see any one thus affected, do your utmost to have him taken at once to the coolest place that is near at hand, and where there is plenty of fresh air. The clothing should be removed and the body sponged with cold water, if the surface is warm; if it is cool, warm water should be used. If the patient's body is very hot, his pulse high, he snores or moans, and is limp and senseless, he should be laid upon his face, his head slightly raised and cold water poured upon it for several minutes, from a height of four or five feet. CAUTION. If the pulse is feeble and fast, the breathing light, and the body cool, the treatment just named would be highly dangerous. The patient must be given small doses of diluted brandy or whiskey, and a blister applied to the back of the neck. Of course a physician will be sent for at once. POISONS. It may happen that a child swallows by mistake some kind of poison (when he is alone), and when a few minutes' delay in reaching a physician will be fatal. The best and indeed the only thing to do is to produce instant vomiting. Stir a tablespoonful of salt or a teaspoonful of mustard in a tumbler of warm water and swallow without a moment's delay. At the end of five minutes, repeat the dose, and continue doing so for half an hour. If vomiting does not take place immediately, bring it on by thrusting the forefinger down the throat, since vomiting alone will save your life. SULPHURIC ACID POISON. There is but one poison which cannot be thrown off by the means just described. If water is drank directly after swallowing sulphuric acid, it will be fatal. Vomiting must be induced by using the finger. A SAFE RULE. The only safe rule for children, as well as for grown persons, is never to swallow or touch anything which they are not certain can do them no harm. When there is the least doubt, leave it alone. * * * * * What is said of sunlight? When should the rays be avoided? What should be carried in the crown of the hat when the sunlight is very strong? Describe the symptoms of sunstroke. What is the first thing to do when a person suffers sunstroke? Suppose the surface of the body is warm? Suppose it is cool? If the body is hot, pulse high, he snores, is limp, etc.? If the pulse is feeble and fast, breathing light, body cool? What course should be followed if poison is taken by mistake? Suppose the dose described does not cause vomiting? What of sulphuric acid? What is the only safe rule? CHAPTER XVII. CIGARETTE SMOKING. I have now a few words to say to the boys. I hope the girls will also listen, and help to impress the words on their friends.
