RODUCTORY LESSONS.

1. My body is built of bones covered with flesh and skin; the blood flows
through it, all the time, from my heart. I breathe through my nose and
mouth, and take the air into my lungs.

2. The parts of my body are the head, the trunk, the limbs.

3. My head.
The crown of my head.

THE NOSE AND THE MOUTH.

Be sure to keep your mouth closed when you are not talking or singing,
especially when you are walking, running, or _asleep_. The two nostrils are
outside doors, always open to admit the air, and inside of the upper part
of the nose there are two other openings, through which it passes into the
throat. Air which goes this way is warmed, cleansed, and moistened, but
that which is breathed directly through the mouth is not so well prepared
for its work in the lungs.

Do not use your mouth as a box or a pin-cushion; the pin, or whatever yon
have put into it, may slip into your throat and cause your death.
