1.  My heart is shaped like a cone, and placed in my chest near my breastbone, with its apex pointing downward to my left side.  It beats about seventy times a minute, sending out about two ounces of blood at every beat.

2.  The blood when pure is of a bright red color; it is a liquid made from food and drink.

3.  It passes from my heart to all parts of my body, through pipes called arteries; these arteries spread out through the body like branches from a tree.

4.  As the blood flows from the heart, through the arteries, it gives nourishment to every part of the body, and carries away the impurities it meets, which makes it black and thick; when it comes through the veins, back to the heart, it is not fit to be used, so it goes to the lungs to be purified by the fresh air; then it returns to the heart to be sent again throughout the body; this happens once in from three to eight minutes, and is called the circulation of the blood.

7.  If I would be healthy,
    my blood must be pure and circulate freely all the time.

8.  It will not circulate freely,
    if I wear tight clothing,
    if I do not exercise in work or play,
    if I do not keep my body warm.

9.  It will be impure,
    if I breathe bad air,
    if I eat unwholesome food,
    if I drink alcoholic liquors,
    if I snuff, smoke, or chew tobacco.

If it is only a flesh-wound or slight cut, wash it with cold water and bandage it with a clean, white rag.  The edges of a deep cut should be drawn together and held in place by narrow strips of adhesive plaster, fastened across the wound from side to side.

If the cut is very deep, and the blood flows very freely, send for a doctor.  While you wait for him, knot a handkerchief, or suspender, or towel, in the middle, and twist it very tightly over the cut artery, above the wound.  If a vein has been severed, twist the knotted handkerchief below the wound.  If the blood continues to flow, tie a bandage both above and below the hurt part.
