1050. LEY.--The ley obtained by the leaching of ashes may be taken by a child accidentally. The antidote is vinegar, or oil of any kind. The vinegar neutralizes the alkali by uniting with it, forming the acetate of potash. The oil unites with the alkali, and forms soap, which is less caustic than the ley. Give, at the same time, large draughts of mucilaginous drinks, as flaxseed tea, &c. -=-=-=-=-=-=-=-=-=-=-=-= 1044. What is the antidote for white vitriol? 1047.

What is the antidote when ley is swallowed? -=-=-=-=-=-=-=-=-=-=-=-= VEGETABLE POISONS. 1051. The vegetable poisons are quite as numerous, and many of them equally as virulent, as any in the mineral kingdom. We shall describe the most common, and which, therefore, are most liable to be taken. 1052. OPIUM.--This is the article most frequently resorted to by those wishing to commit suicide, and, being used as a common medicine, is easily obtained. From this cause, also, mistakes are very liable to be made, and accidents result from it. Two of its preparations, _laudanum_ and _paregoric_, are frequently mistaken for each other; the former being given when the latter is intended. 1053. _Morphia_, in solution, or _morphine_, as it is more commonly called by the public, is a preparation of the drug under consideration, with which many cases of poisoning are produced. It is the active narcotic principle of the opium; and one grain is equal to six of this drug in its usual form. 1054. When an over-dose of opium, or any of its preparations, has been swallowed, the stomach should be evacuated as speedily as possible. To effect this, a teaspoonful of ground mustard seed, or as much tartar emetic as can be held on a five cent piece, or as much _ipecacuanha_ as can be held on a twenty-five cent piece, should be mixed in a tumbler of warm water, and one half given at once, and the remainder in twenty minutes, if the first has not, in the mean time, operated. In the interval, copious draughts of warm water, or warm sugar and water, should be drank. 1055. The use of the stomach-pump, in these cases, is of the greatest importance, and should be resorted to without delay. After most of the poison has been evacuated from the stomach, a strong infusion of _coffee_ ought to be given; or some one of the vegetable acids, such as _vinegar_, or _lemon-juice_, should be administered.
