Amount of Watery Vapor Discharged from the Body.—The amount of fluid which is lost from the body both by the skin and lungs, is about eighteen grains per minute, eleven by the skin and seven by the lungs. This amount, however, varies exceedingly with the state of the health and the dryness or moisture of the air, which, as already men- tioned, regulates the temperature of the system. 528.

This amount, however, varies exceedingly with the state of the health and the dryness or moisture of the air, which, as already men- tioned, regulates the temperature of the system. 528. The Hair.—The hair is distributed over nearly every portion of the human frame, and presents differences according to age, sex, race, or individ- ual peculiarities. In length, the hair is most fully devel- oped on the heads of females, sometimes equaling the length of the body^ while in male beards it seldom reaches to the waist. The coarsest hair is also found on women. 529. Size of the Hair- Oil Glands,—In diameter the hair varies from jjo^ to o-0-Voth of an inch, and its section is always of an oval outline, but never circular. Nor is the hair of a uniform diameter, but it is spindle- shaped almost always, and terminates m a point. At its base it expands into a bulb which is lodged in a sac in the true skin, as is seen in Fig. 295, p. 303. Just beneath the epidermis one or more glands are situated which empty their 527.
