_Lime_ or _baryta_ and its compounds demand a solution of glauber salts or of sulphuric acid. _Iodine_ or _Iodide of Potassium_ demands large draughts of wheat flour or starch in water, and then vinegar and water. The stomach should then be emptied by vomiting with as much tepid water as the stomach can hold. _Prussic Acid_, a violent poison, is sometimes taken by children in eating the pits of stone-fruits or bitter almonds which contain it. The antidote is to empty the stomach by an emetic, and give water of ammonia or chloric water. Affusions of cold water all over the body, followed by warm hand friction, is often a remedy alone, but the above should be added if at command. _Antimony_ and its compounds demand drinks of oak bark, or gall-nuts, or very strong green tea. _Arsenic_ demands oil or melted fat, with magnesia or lime water in large quantities, till vomiting occurs. _Corrosive Sublimate_, (often used to kill vermin,) and any other form of mercury, requires milk or whites of eggs in large quantities. The whites of twelve eggs in two quarts of water, given in the largest possible draughts every three minutes till free vomiting occurs, is a good remedy. Flour and water will answer, though not so surely as the above. Warm water will help, if nothing else is in reach. The same remedy answers when any form of copper, or tin, or zinc poison is taken, and also for creosote. _Lead_ and its compounds require a dilution of Epsom or Glauber salts, or some strong acid drink, as lemon or tomatoes. _Nitrate of Silver_ demands salt water drank till vomiting occurs. _Phosphorus_ (sometimes taken by children from matches) needs magnesia and copious drinks of gum Arabic, or gum-water of any sort. _Alcohol_, in dangerous quantities, demands vomiting with warm water. When one is violently sick from excessive use of _tobacco_, vomiting is a relief, if it arise spontaneously. After that, or in case it does not occur, the juice of a lemon and perfect rest, in a horizontal position on the back, will relieve the nausea and faintness, generally soothing the foolish and overwrought patient into a sleep. _Opium_ demands a quick emetic. The best is a heaping table-spoonful of powdered mustard, in a tumblerful of warm water; or powdered alum in half-ounce doses and strong coffee alternately in warm water. Give acid drinks after vomiting. If vomiting is not elicited thus, a stomach-pump is demanded. Dash cold water on the head, apply friction, and use all means to keep the person awake and in motion. _Strychnia_ demands also quick emetics. The stomach should be emptied always after taking any of these antidotes, by a warm-water emetic. In case of bleeding at the lungs, or stomach, or throat, give a tea-spoonful of dry salt, and repeat it often. For bleeding at the nose, put ice or pour cold water on the back of the neck, keeping the head elevated.
