Always send immediately for a medical men. Save all fluids vomited, and articles of food, cups, glasses, etc., used by the patient before taken ill, and lock them up. This precaution frequently leads to the detection of crime.

As a rule, give emetics after poisons that cause sleepiness and ravings: chalk, milk, eggs, butter, and warm water, or oil, after poisons that cause vomiting and pain in the stomach and bowels, with purging; and when there is no inflammation about the throat, tickle it with a feather to excite vomiting.

Vomiting may be caused by giving warm water, with a teaspoonful of mustard to the tumblerful, well stirred up. Sulphate of zinc (with vitriol) may be used in place of the mustard, or powdered alum. Powder of ipecacuanha, a teaspoonful rubbed up with molasses, may be employed for children. Tartar emetic should never be given, as it is excessively depressing, and uncontrollable in its effects. The stomach pump can only be used by skillful hands, and even then with caution.

In opium and other narcotics, after vomiting has occurred, cold water should be dashed over the face and head. The patient must be kept awake, walked about between two strong persons, made to grasp the handles of a galvanic battery, dosed with strong coffee, and vigorously slapped. Belladonna is an antidote for opium and for morphia, etc., its active principle; and, on the other hand, the latter counteract the effects of belladonna. But a knowledge of medicines is necessary for dealing with these articles.

In the case of strychnia, after emetics have been freely and successfully given, the patient should be allowed to breathe the vapor of sulphuric ether, poured on a hand-erchief and held to the face, in such quantities as to keep down the tendency to convulsions. Bromide of potassium, twenty grains to a dose, dissolved in syrup, may be given every hour.

Alcoholic poisoning should be combated by emetics, of which the sulphate of zinc, given as above directed, is the best. After that, strong coffee internally, and stimulation by heat externally, should be used.

Acids are sometimes swallowed by mistake. Alkalies, lime water, magnesia, or common chalk mixed with water, may be freely given, and afterward mucilaginous jinks, such as thick gum water or flaxseed tea.

Alkalies are less frequently taken in injurious strength or quantity, but sometimes children swallow lye by mistake. Common vinegar may be given freely, and then castor or sweet oil in full doses - a tablespoonful at a time, repeated every half hour or two.

Nitrate of silver when swallowed is neutraitzed by common table salt freely given in solution in water.
