Poisons, (Accidents From). When you have reason to suppose that you have swallowed poison, and proper medical advice is not at hand, take an emetic. This may be done almost instantaneously by swallow -: ig a cupful of warm water mixed with a spoonful of mustard. As mustard may thus prove of so much use, it should be never wanting in any house; but even should there be no mustard at hand, warm water by itself forms a tolerably efficacious emetic. The following is a good emetic in ease of Vegetable Poisons. - Twenty grains of sulphate of zinc dissolved in a little water, the whole to be taken ; or sulphate of zinc, one scruple, made into a bolus with confection of roses, and taken with infusion of camomile flowers.

Poisonous Vegetables. Everybody who has observed wild plants or weeds must have been struck with the resemblance many bear to parsley. Parents and nurses of children should be careful not to allow then? to pick any parsley-like wild plants, as they are for the most part poisonous. Should it appear that a child has swallowed a portion of a plant of this nature, it is important to know what to give before the arrival of a medical man. Every ten minutes, therefore, administer a large dose of olive or salad oil, with warm water, till free sickness is produced. A teaspoonful or two of vinegar, given after vomiting has been fully excited, has been found beneficial.

Antidote for Laudanum. Give twenty grains of white vitriol dissolved in water, and assist vomiting by irritating the fauces with a feather; after the stomach is emptied, give large draughts of vinegar and water, and other vegetable acids, with coffee, brandy, &, constantly rousing the attention of the sufferer, until the effects of the poison subside. Recourse maybe had to this until the attendance of a medical man can be procured.

Antidote to Arsenic. Magnesia is an antidote to arsenic, equally eflicacious with peroxide of iron, and preferable to it, inasmuch as it is completely innocuous in almost any quantity .and can be procured in any form.

Vitriol Accidents are not uncommon in kitchens, as when oil of vitriol (improperly used for cleaning copper vessels) is let fall upon the hands, etc. Let a little soda or potash be dissolved in water, or some fresh soapboilers' lees, and instantly applied; no injury whatever will occur to the person or clothes.
