tongue
itself, may fall forward, and leave the entrance into the windpipe free.

3d, _To excite respiration_, turn the patient slightly on his side, and
apply some irritating or stimulating agent to the nostrils, as
_veratrine_, _dilute ammonia_, &c.

4th, Make the face warm by brisk friction; then dash cold water upon it.

5th, If not successful, lose no time; but, _to imitate respiration_,
place the patient on his face, and turn the body gently but completely
_on the side and a little beyond_, then again on the face, and so on
alternately. Repeat these movements deliberately and perseveringly,
_fifteen times only_ in a minute. (When the patient lies on the thorax,
this cavity is _compressed_ by the weight of the body, and _ex_piration
takes place. When he is turned on the side, this pressure is removed,
and _in_spiration occurs.)

6th, When the prone position is resumed, make a uniform and efficient
pressure _along the spine_, removing the pressure immediately, before
rotation on the side. (The pressure augments the _ex_piration, the
rotation commences _in_spiration.) Continue these measures.

7th, Rub the limbs _upward_, with _firm pressure_ and with _energy_.
(The object being to aid the return of venous blood to the heart.)

8th, Substitute for the patient's wet clothing, if possible, such other
covering as can be instantly procured, each bystander supplying a coat
or cloak, &c. Meantime, and from time to time, _to excite inspiration_,
let the surface of the body be _slapped_ briskly with the hand.

9th, Rub the body briskly till it is dry and warm, then dash _cold_
water upon it, and repeat the rubbing.

Avoid the immediate removal of the patient, as it involves a _dangerous
loss of time_; also the use of bellows or any _forcing_ instrument; also
the _warm bath_ and _all rough treatment_.

POISONS.

In all cases of poisoning, the first step is to evacuate the stomach.
This should be effected by an emetic which is _quickly_ obtained, and
most powerful and speedy in its operation. Such are, powdered mustard
(a large tablespoonful in a tumblerful of warm water), powdered alum
(in half-ounce doses), sulphate of zinc (ten to thirty grains), tartar
emetic (one to two grains) combined with powdered ipecacuanha (twenty
grains), and sulphate of copper (two to five grains). When vomiting has
already taken place, copious draughts of warm water or warm mucilaginous
drinks should be given, to keep up the effect t
