and. If the dry mustard is not to be had, use
mixed mustard from the mustard pot. Its operation may generally be
facilitated by the addition of a like quantity of common table salt. If
the mustard is not at hand, give two or three teaspoonfuls of powdered
alum in syrup or molasses, and give freely of warm water to drink; or
give ten to twenty grains of sulphate of zinc (white vitriol), or twenty
to thirty grains of ipecac, with one or two grains of tartar emetic, in
a large cup of warm water, and repeat every ten minutes until three or
four doses are given, unless free vomiting is sooner produced. After
vomiting has taken place, large draughts of warm water should be given
the patient, so that the vomiting will continue until the poisonous
substances have been thoroughly evacuated, and then suitable antidotes
should be given. If vomiting cannot be produced, the stomach-pump should
be used. When it is known what particular kind of poison has been
swallowed, then the proper antidote for that poison should be given, but
when this cannot be ascertained, as is often the case, give freely of
equal parts of calcined magnesia, pulverized charcoal, and sesquioxide
of iron, in sufficient quantity of water. This is a very harmless
mixture, and is likely to be of great benefit, as the ingredients,
though very simple, are antidotes for the most common and active
poisons. In case this mixture cannot be obtained, the stomach should be
soothed and protected by the free administration of demulcent,
mucilaginous or oleaginous drinks, such as the whites of eggs, milk,
mucilage of gum arabic, or slippery elm bark, flaxseed tea, starch,
wheat, flour, or arrow-root mixed in water, linseed or olive oil, or
melted butter or lard. Subsequently the bowels should be moved by some
gentle laxative, as a tablespoonful or two of castor oil, or a
teaspoonful of calcined magnesia; and pain or other evidence of
inflammation must be relieved by the administration of a few drops of
laudanum, and the repeated application of hot poultices, fomentations
and mustard plasters. The following are the names of the articles that
may give rise to poisoning, most commonly used, and their antidote:

MINERAL ACIDS--SULPHURIC ACID (OIL OF VITRIOL), NITRIC ACID (AQUA
FORTIS), MURIATIC ACID (SPIRITS OF SALTS).--Symptoms: Acid, burning
taste in the mouth, acute pain in the throat, stomach and bowels;
frequent vomiting, generally bloody, mouth and lips excoriated,
