This may occur at once,
or in the course of a little time. The pain from the second kind of
burns is much more severe than that in the other two, although the
danger, as a general rule, is less than it is in the third class. These
injuries are much more dangerous when they take place on the trunk than
when they happen on the arms or legs. The danger arises more from the
extent of surface that is burnt than from the depth to which the burn
goes. This rule, of course, has certain exceptions; because a small burn
on the chest or belly penetrating deeply is more dangerous than a more
extensive but superficial one on the arm or leg. When a person's clothes
are in flames, the best way of extinguishing them is to wind a rug, or
some thick material, tightly round the whole of the body.

2620. _Treatment of the First Class of Burns and Scalds_.--_Of the part
affected_.--Cover it immediately with a good coating of common flour, or
cotton-wool with flour dredged well into it. The great thing is to keep
the affected surface of the skin from the contact of the air. The part
will shortly get well, and the skin may or may not peel
off.--_Constitutional Treatment_. If the burn or scald is not extensive,
and there is no prostration of strength, this is very simple, and
consists in simply giving a little aperient medicine--pills (No. 2), as
follows:--Mix 5 grains of blue pill and the same quantity of compound
extract of colocynth, and make into two pills--the dose for a full-grown
person. Three hours after the pills give a black draught. If there are
general symptoms of fever, such as hot skin, thirst, headache, &c. &c.,
two tablespoonfuls of fever-mixture are to be given every four hours.
The fever-mixture, we remind our readers, is made thus:-Mix a drachm of
powdered nitro, 2 drachms of carbonate of potash, 2 teaspoonfuls of
antimonial wine, and a tablespoonful of sweet spirits of nitro, in half
a pint of water.

2621. _Second Class. Local Treatment_.--As the symptoms of these kinds
of burns are more severe than those of the first class, so the remedies
appropriate to them are more powerful. Having, as carefully as possible,
removed the clothes from the burnt surface, and taking care not to break
the bladders, spread the following liniment (No. 1) on a piece of linen
or lint--not the _fluffy_ side--and apply it to the part: the liniment
should be equal parts of lime-water and linseed-oil, well mixed. If the
burn is on the trunk of the
