omething having an explosive effect and may be accompanied
by hemorrhage, shock and even loss of function; they may be arterial
or venous.

POISONED WOUNDS are of two sorts; external and internal.

DIAGNOSIS TAG.--This tag placed on a soldier shows wound, name, rank,
regiment, treatment received, etc. This tag should be carefully read
before further treatment is accorded.

TREATMENT OF WOUNDS.--The compress, of the first aid packet will
always prove of help.

BLEEDING WOUNDS.--The bandage of the first aid packet will stop all
ordinary bleeding; but in aggravated cases the bleeding may be stopped
by pressure on the artery, between the wound and the heart. This may
be done by hand or by means of the forceps in the medical pouch. The
points of compression should be learned and located; in front of the
ear just above the socket of the jaw; in the neck in front of the
strongly marked muscle reaching from behind the ear to the upper part
of the breast bone; in the hollow behind the collar bone; just behind
the inner border of the larger muscle of the arm; the femoral artery
at the middle of the groin where the artery passes over the bone.
Bleeding may also be stopped to some extent by elevating the wounded
part. A tourniquet may be improvised by using the compress, running a
stick or the bayonet through the band, and taking up the slack by
twisting.

POISONED WOUNDS.--For a _snakebite_ make a tight constriction just
above the wound; make an incision at the bite and suck out the poison.
_Do it quickly_. If this is impossible, follow the same plan but give
a stimulant; repeatedly loosen the constriction and let a little of
the poison into the system at a time to be neutralized. In cases of
chemical poisoning do not follow the usual method of treating
poisoning. _Do not make the patient vomit_, but give him something fat
or albuminous such as raw eggs or milk. This forms mercurial
albuminate. _Ptomaine_ poisoning (symptoms are headache, cramps,
nausea, high fever and chills, etc.). Drink salt water, vomit and
repeat the procedure to clean out the stomach. A purgative should also
be taken. Ice cream and milk kept too long are frequent causes of this
sort of poisoning, as are dishes kept in the icebox over night.

FAINTING, HEAT EXHAUSTION AND SHOCK are all of the same class;
symptoms are the same--weak pulse, paleness and low temperature,
tendency to fall to ground. Often follows taking too much water on the
march. Treatm
