ng difficult. Convulsions and insensibility often occur,
and are very bad symptoms indeed. The inside of the mouth is more or
less swollen.--_Treatment_. Mix the whites of a dozen eggs in two pints
of cold water, and give a glassful of the mixture every three or four
minutes, until the stomach can contain no more. If vomiting does not now
come on naturally, and supposing the mouth is not very sore or much
swollen, an emetic draught, No. 1, may be given, and vomiting induced.
(The No. 1 draught, we remind our readers, is thus made:--Twenty grains
of sulphate of zinc in an ounce and a half of water; the draught to be
repeated if vomiting does not take place in a quarter of an hour.) After
the stomach has been well cleaned out, milk, flour-and-water, linseed-tea,
or barley-water, should be taken in large quantities. If eggs cannot be
obtained, milk, or flour-and-water, should be given as a substitute for
them at once. When the depression of strength is very great indeed, a
little warm brandy-and-water must be given. In the course of an hour or
two the patient should take two tablespoonfuls of castor-oil, and if
inflammation comes on, it is to be treated as directed in the article on
acids and alkalis. The diet should also be the same. If the patient
recovers, great soreness of the gums is almost certain to take place. The
simplest, and at the same time one of the best modes of treatment, is to
wash them well three or four times a day with brandy-and-water.

2658. _Calomel_.--A heavy white powder, without taste, and insoluble in
water. It has been occasionally known to destroy life.--_Symptoms_. Much
the same as in the case of corrosive sublimate.--_Treatment_. The same
as for corrosive sublimate. If the gums are sore, wash them, as
recommended in the case of corrosive sublimate, with brandy-and-water
three or four times a day, and keep the patient on _fluids_, such as
arrowroot, gruel, broth, or beef-tea, according to the other symptoms.
Eating hard substances would make the gums more sore and tender.

2659. _Copper_.--The preparations of this metal which are most likely to
be the ones producing poisonous symptoms, are _blue-stone_ and
_verdigris_. People are often taken ill after eating food that has been
cooked in copper saucepans. When anything has been cooked in one of
these vessels, _it should never be allowed to cool in it_.--_Symptoms_.
Headache, pain in the stomach, and purging; vomiting of green or blue
matters, c
