ANTIDOTES FOR POISONS The antidotes for poisoning with the strong mineral acids, such as nitric, muriatic, sulphuric, or oxalic acids are magnesia, chalk, whiting, in milk or water; mucilaginous or soapy liquids. When sulphuric acid has been taken, use very little water if any. Irritate the throat with a feather to produce vomiting. The antidote for poisoning with corrosive sublimate or any other preparation of mercury, is albumen, as whites of eggs, in large quantity, flour and water, and milk. The whites of eggs are best. The antidotes for poisoning by opium, or any of its preparations, as morphia, laudanum, &c., are the stomach pump if it can be had; tartar emetic, 2 to 5 grains, or sulphate of zinc, 15 to 30 grains, or sulphate of copper, 12 to 15 grs., for an adult. The sulphates of zinc or copper are best, because they act quicker. External excitation, keep in motion, mechanical excitement of respiration, cold effusion to the head and face, feet in hot water, electro-magnetism, internal stimulants, as bicarbonate of ammonia, 5 to 25 grains in water, carbonate of ammonia, 5 to 15 grains in water, coffee and vegetable acids. Some propose as an antidote for every case of poisoning, half a pint of bland oil, as sweet oil, fresh butter melted to oil, &c., to be drank at once, for an adult. 513. TREATMENT OF DROWNING
