The skull consists of eight' bonds, four at the top and four in pairs at tbo sides. There are three kinds of teeth, thetocisbrs, the tearing and the grinders, and in many the t hree kinds are opposite to each other, above and below. The number of teeth at maturity is thirty-two, or sixteen to each jaw. The perspiration of a man in health is about twenty-eight ounces in twenty-four hours. This fact alone shows the necessity of bathing and washing the skin. The quantity diminishes while eating, but increases during digestion and sleep. The blood is about the fifth of the weight of the body. Th® heart, by its muscular contraction, distributes two ounces of blood from seventy to eighty times in a minute. The lungs, owing to the continued reception of fresh cold air, are the coldest part of the body. In sleep the respiration Is less frequent than at other times.. A respiration may be held for a minute and. a half, or even if it be taheu deep and long.
