Hair is a non-conductor of heat,—that is, very little heat or cold can be made to pass through it. It serves as a protection to the brain. While a great many men are baldheaded, you very rarely see a woman thus afflicted. This is because they do not wear air-tight coverings for their heads, but the scalp is kept cool and healthy. It is a good thing for children to leave off their hats and caps, except when necessary to protect them out-of-doors.
THE EAR.
THE EAR.—Showing External Ear and Internal Ear. (1) Auditory Canal, (2) Drum of the Ear, (3, 4, 5, 6) Bones of the Ear, (7, 8, 9, 10) Semi-circular Canals, and Cochlea or Snail Shell, (11) Eustachian Tube, leading to Throat.
The ears need even less care than the hair, for that which is called by the name, is only the covering of the true ear. Every boy and girl will make sure that when the face and hands are washed, the neck and ears are not forgotten. The shape of the outer ear causes it to catch many of the particles always floating in the air. These can be easily removed with the end of the forefinger, covered by a portion of a moist towel.
Do not pick the ears. The wax is placed there by nature for a wise purpose. It keeps out dirt and insects and protects from injury the delicate organs of the true ear within. If the wax becomes too abundant or hard, it can be easily removed with the forefinger. If anything more is required, go to a doctor.
THE EYE.
The eye is the most wonderful organ of the body, and with simple care can be preserved all through life. Boys and girls who have bright, strong eyes are apt to weaken them by carelessness in their use.
THE EYE.—Showing Iris, Pupil, (G) Tear Gland, (D) Tear Lake, (C) Tear Duct, leading to nose.
