ist of arrowroot or gruel for the first few
days, and then of weak broth or beef-tea for some time after.

2655. When very strong fumes of smelling-salts have in any way been
inhaled, there is great difficulty of breathing, and alarming pain in
the mouth and nostrils. In this case let the patient inhale the steam of
warm vinegar, and treat the feverish symptoms as before.

2656. _Arsenic_.--Mostly seen under the form of white arsenic, or
fly-powder, and yellow arsenic, or king's yellow.--_Symptoms produced in
those who have swallowed it_. These vary very much, according to the
form and dose in which the poison has been taken. There is faintness,
depression, and sickness, with an intense burning pain in the region of
the stomach, which gets worse and worse, and is increased by pressure.
There is also vomiting of dark brown matter, sometimes mixed with blood;
and mostly great thirst, with a feeling of tightness round, and of
burning in, the throat. Purging also takes place, the matters brought
away being mixed with blood. The pulse is small and irregular, and the
skin sometimes cold and clammy, and at others hot. The breathing is
painful. Convulsions and spasms often occur.--_Treatment_. Give a couple
of teaspoonfuls of mustard in a glass of water, to bring on or assist
vomiting, and also use the other means elsewhere recommended for the
purpose. A solution, half of lime-water and half of linseed-oil, well
mixed, may be given, as well as plenty of arrowroot, gruel, or
linseed-tea. Simple milk is also useful. A little castor-oil should be
given, to cleanse the intestines of all the poison, and the
after-symptoms treated on general principles.

2657. _Corrosive Sublimate_.--Mostly seen in the form of little heavy
crystalline masses, which melt in water, and have a metallic taste. It
is sometimes seen in powder. This is a most powerful poison.--_Symptoms_.
These mostly come on immediately after the poison has been taken. There
is a coppery taste experienced in the act of swallowing, with a burning
heat, extending from the top of the throat down to the stomach; and also
a feeling of great tightness round the throat. In a few minutes great
pain is felt over the region of the stomach, and frequent vomiting of
long, stringy white masses, mixed with blood, takes place. There is
also mostly great purging. The countenance is generally pale and
anxious; the pulse always small and frequent; the skin cold and clammy,
and the breathi
