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.
