EFFECTS OF EXERCISE.

How many muscles have you? How are the bones moved?
How are the muscles generally found? In what manner do they work?
What is a voluntary muscle? An involuntary one? Illustrate the difference.

Why should the muscles he trained? What is the result?
What kind of medicine is such exercise? How must your strength be built up?

CHAPTER XII.
REST AND POSTURE.
“Early to bed and early to rise” should be your motto. Children need abundant sleep, and ought to retire early and rise as soon as they awake in the morning. Their bodies and brains require regular rest.
Never lie on your back when sleeping, but on the left or right side. Place your limbs in the easiest position possible; otherwise you will be troubled by bad dreams, which will awake you from slumber. Try to keep your mouth closed, so as to breathe through your nostrils. You will thus escape the unpleasant habit of snoring.
