ollows: The
_whites of a dozen eggs_ should be beaten in two quarts of cold water,
and a tumbler-full given every two minutes, to induce vomiting. When
the whites of eggs are not to be obtained, soap and water should be
mixed with wheat flour, and given in copious draughts, and the
stomach-pump introduced as soon as possible. Emetics or irritating
substances should not be given.

1043. NITRE--_Saltpetre._--This, in over-doses, produces violent
poisonous symptoms. Vomiting should be immediately induced by large
doses of mucilaginous, diluent drinks; but emetics which irritate the
stomach should not be given.

1044. ZINC.--Poisoning is sometimes caused by the _sulphate of zinc_,
(white vitriol.) When this takes place, vomiting should be induced,
and aided by large draughts of mucilaginous and diluent drinks. Use
the stomach-pump as soon as possible.

1045. The antidote is the _carbonate_, or _super-carbonate of soda_.

1046. NITRIC, (aqua fortis,) MURIATIC, (MARINE ACID,) OR SULPHURIC
(OIL OF VITRIOL,) ACIDS, may be taken by accident, and produce
poisonous effects.

1047. The antidote is _calcined magnesia_, which should be freely
administered, to neutralize the acid and induce vomiting. When
magnesia cannot be obtained, the _carbonate of potash_ (salaeratus) may
be given. _Chalk_, powdered and given in solution, or strong _soap
suds_, will answer a good purpose, when the other articles are not at
hand. It is of very great importance that something be given speedily,
to neutralize the acid. One of the substances before mentioned should
be taken freely, in diluent and mucilaginous drinks, as gum-water,
milk, flaxseed, or slippery-elm tea. Emetics ought to be avoided.

1048. OXALIC ACID.--This acid resembles the sulphate of magnesia,
(epsom salts,) which renders it liable to be taken, by mistake, in
