Object Lessons on the Human Body.
by Sarah F. Buckelew and Margaret W. Lewis.
AUTHOR"S NOTE TO THE PUPIL
This book has been prepared to help you in learning about "the house you live in," and to teach you to take care of it, and keep it from being destroyed by two of its greatest enemies,--Alcohol and Nicotine.
As you study its pages, be sure to find out the meaning of every word in them which you do not understand; for, if you let your tongue say what your mind knows nothing about, you are talking _parrot-fashion_.
And do not forget that you must pay for all the knowledge you obtain, whether you are rich or poor. n.o.body else can pay for you. You, your own self, must _pay attention_ with your own mind, through your own eyes and ears, _or do without knowledge_.
Be wise: gain all the knowledge you can concerning everything worth knowing, and use it for the good of yourself and other people.
"KNOWLEDGE IS POWER."
[Ill.u.s.tration: A, the heart; B, the lungs; light cross lines, arteries; heavy lines, veins.]

3. My head.
The crown of my head.
The back of my head.

QUESTIONS FOR THE FORMULA.
1. Tell about your body.
2. Name the parts of the body.
3. Name the parts of the head, trunk, and limbs.
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 pa.s.ses 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.
