Bleeding is sometimes necessary at once in certain accidents, such as concussion, and therefore it is well to know how to do this. First of all, bind up the arm above the elbow with a piece of bandage or a handkerchief, pretty firmly, then place your finger over the veins at the bend of the arm, and feel if there is any pulsation; if there is, try another vein, and if it does not pulsato or beat, choose that one- Now rub the arrn, from the wrist towards the elbow, place the left thumb upon the vein, and hold the lancet as you would pen, and nearly at right angles to the vein, taking care to prevent its going in too far, by keeping the thumb near to the point, and resting the hand upon the little finger. Now place the point of the lancet on the vein; push it suddenly inwards, depress the elbow, and raise the hand upwards and outwards so as to cut obliquely across the vein. When sufficient blood is drawn off, which is known by feeling the pulse at the wrist, and near the thumb, bandage the arm. If the pulse feel like apiece of cord, more blood should be taken away, but if it is soft, and can be easily pressed, the bleeding should be stopped. When you bandage the arm, place a piece of lint over the opening made by the lancet, and pass a bandage lightly, but firmly, around the arm, so as to cross it over the bend of the elbow.

2227. Dry Cupping is performed by throwing a piece of paper dipped into spirit of wine, and ignited into a wine-glass, and placing it over the part, such as the neck, temples, etc. It thus draws the flesh into the glass, and causes a termination of blood to the part, which is useful in headache, or many other complaints. This is an excellent method of extracting the poison from wounds made by adders, mad dogs, fish, etc.

2228. Ordinary Cupping is performed the same as dry cupping, with this exception, that the part is scarified or scratched with a lancet, so as to cause the blood to flow. Then the glass is placed over it again with the lighted paper in it, and when sufficient blood has been taken away, then the parts are sponged, and a piece of sticking plaster applied over them.
