POISONS.
In all cases of poisoning, the first step is to evacuate the stomach. This should be effected by an emetic which is quickly obtained, and most powerful and speedy in its operation. Such are, powdered mustard (a large tablespoonful in a tumblerful of warm water), powdered alum (in half-ounce doses), sulphate of zinc (ten to thirty grains), tartar emetic (one to two grains) combined with powdered ipecacuanha (twenty grains), and sulphate of copper (two to five grains). When vomiting has already taken place, copious draughts of warm water or warm mucilaginous drinks should be given, to keep up the effect till the poisoning substance has been thoroughly evacuated.
