When should you cease using the eyes? What should be done if a cinder gets under the lid?
What should be done if that fails?
When must spectacles be used, or an oculist consulted?
How must the feet be kept? Which are the better, cotton or woolen stockings? What of tight shoes? What should be done with the nails?
CHAPTER VI.
THE TEETH.
Few boys and girls take proper care of their teeth. All of us admire a set of strong, sound, even, white teeth, and those who do not have such, will tell how sorry they are because in youth they were so careless that their teeth were ruined.
The teeth should be carefully cleaned each morning before breakfast. This is best done with a good brush, Castile soap, and lukewarm water. Use none of the numerous tooth-powders sold, and never pick your teeth with a metallic substance. Quill, wooden, or ivory tooth-picks only should be employed.
When the brush does not remove the stains from the teeth, the soft end of a small stick, covered with powdered charcoal will answer, though it should not be used often.
INJURIES TO THE TEETH.
Very hot or cold food, or water, sweetmeats and acids injure the teeth. Children sometimes like to show the strength of their teeth by cracking hickory-nuts and other hard substances. This should never be done, as the nuts and substances may prove stronger than the teeth. The teeth are made of a soft kind of bone, covered with enamel. The bone part of the teeth soon decays if the enamel is broken.
