ACIDS: _Nitric_ (aqua fortis), _hydrochloric_ (muriatic), _sulphuric_ (oil of vitriol), _oxalic_, etc.--Drink a little water to weaken the acid, or, still better, take strong soapsuds. Stir some magnesia in water, and drink freely. If the magnesia be not at hand, use chalk, soda, lime, whiting, soap, or even knock a piece of plaster from the wall, and scraping off the white outside coat pound it fine, mix with milk or water, and drink at once. Follow with warm water, or flaxseed tea. ALKALIES: _Potash, soda, lye, ammonia_ (hartshorn).--Drink weak vinegar or lemon juice. Follow with castor or linseed oil, or thick cream. ANTIMONY: _Antimonial wine, tartar emetic_, etc.--Drink strong, green tea, and in the meantime chew the dry leaves. The direct antidote is a solution of nutgall or oak bark. ARSENIC: _Cobalt, Scheele's green, fly powder, ratsbane_, etc.--Give _plenty of milk, whites of eggs_, or induce vomiting by mustard and warm water; [Footnote: See that the mustard is well mixed with the water, in the proportion of about half an ounce of the former to a pint of the latter.] or even soapsuds. BITE OF A SNAKE OR A MAD DOG.--Tie a bandage above the wound, if on a limb. Wash the bite thoroughly, and, if possible, let the person suck it strongly. Rub some lunar caustic or potash in the wound, or heat the point of a small poker or a steel sharpener white hot, and press it into the bite for a moment. It will scarcely cause pain, and will be effectual in arresting the absorption of the poison, unless a vein has been struck. COPPER: _Sulphate of copper_ (blue vitriol), _acetate of copper_ (verdigris).--Take whites of eggs or soda. Use milk freely. LAUDANUM: _Opium, paregoric, soothing cordial, soothing syrup_, etc. --Give an emetic at once of syrup of ipecac, or mustard and warm water, etc. After vomiting, use strong coffee freely. _Keep the patient awake_ by pinching, pulling the hair, walking about, dashing water in the face, and any expedient possible. LEAD: _White lead, acetate of lead_ (sugar of lead), _red lead_.--Give an emetic of syrup of ipecac, or mustard and warm water, or salt and water. Follow with a dose of Epsom salts. MATCHES: _Phosphorus_.--Give magnesia, chalk, whiting, or even flour in water, and follow with mucilaginous drinks. MERCURY: _Calomel, chloride of mercury_ (corrosive sublimate, bug poison), _red precipitate_.--Drink milk copiously. Take the whites of eggs, or stir flour in water, and use freely. NITRATE OF SILVER (lunar caustic).--Give salt and water, and follow with castor oil. NITRATE OF POTASH (saltpeter, niter).--Give mustard and warm water, or syrup of ipecac. Follow with flour and water, and cream or sweet oil. PRUSSIC ACID (oil of bitter almonds), _cyanide of potassium_.--Take a teaspoonful of hartshorn in a pint of water. Apply smelling salts to the nose, and dash cold water in the face.
