By all means keep away from heat. To toast frost-bitten fingers or
toes before a fire is liable to result in chilblains.

=1504. Headache.= Among troops headache is usually due to intestinal
indigestion, combined with a congestion of the stomach. Take a
tablespoonful of Worcestershire sauce or 5 drops of tobasco sauce in a
tumbler of hot water as a drink and put a small piece of soap up into
the bowel to cause a movement.

=1505. Heat exhaustion.= The man falls out in a faint while marching,
or on fatigue or parade. He looks pale, his body is clammy and cold,
his breathing is sighing and heart fluttering. _What is the matter?_
His heart is weak from poisons in the blood, usually alcohol, but
often too much carbonic gas and too little oxygen. This occurs when
men are soft-muscled: so, young soldiers, recruits and fat soldiers
and especially those who drink alcohol, use drugs or smoke or chew
tobacco while hiking, are the first to have it.

_Treatment._ Loosen the man's clothing, remove his pack, lay him on
his back in the shade, with head and shoulders lower than his hips and
raise his feet in the air. This will make the blood flow to the heart
and brain. If he has fainted, slap the bare chest with the hand or a
wet towel and briskly rub the arms towards the heart. If he does not
revive, apply hot bottles, or bricks to the chest and abdomen, and
ammonia to the nose, as a smelling salt. Do not give stimulants until
he is conscious. He should ride in the ambulance, or go to the
hospital.

=1506. Lightning.= A man struck by lightning is treated the same as in
the case of drowning, omitting, of course, the operation of getting
the water out of the lungs.

=1507. Nose, foreign body in.= If it cannot be sneezed out, lean the
head back and pour a little oil into the nostril. Then snift and blow
the nose alternately. If this is not successful, take a lead pencil
and try to push the object straight back into the throat. This must be
done very gently.

=1508. Poison.= When poison has been swallowed, cause the patient to
take a large quantity of luke-warm water and make him vomit by putting
his finger in his throat. Repeat this and then have him swallow the
white of two eggs or some milk into which raw flour or corn-starch has
been stirred.

If you know he took bichloride of mercury, you may increase the amount
of eggs and give one-half glass of weak lime water.

If you know he took carbolic acid, give him alcohol (pur
