CHAPTER III.

THE INSIDE OF THE BODY.

~1.~ Thus far we have taken only a brief look at the outside of the
body, just as if we had looked at the case of a watch, and of course we
have found out very little about its many wonderful parts. Very likely
you want to ask a great many questions, such as, How does the inside of
the body look? What is in the skull? What is in the chest? What is in
the abdomen? Why do we eat and drink? Why do we become hungry and
thirsty? What makes us tired and sleepy? How do we keep warm? Why do we
breathe? How do we grow? How do we move about? How do we talk, laugh,
and sing? How do we see, hear, feel, taste, and smell? How do we
remember, think, and reason? All these, and a great many more
interesting questions, you will find answered in the following lessons,
if you study each one well.

~2.~ When we study the inside of the body, we begin to understand how
wonderfully we are made. We cannot all see the inside of the body, and
it is not necessary that we should do so. Many learned men have spent
their whole lives in seeking to find out all about our bodies and the
bodies of various animals.

~3. The Bones.~--If you take hold of your arm, it seems soft on the
outside; and if you press upon it, you will feel something hard inside.
The soft part is called _flesh_. The hard part is called _bone_. If you
wish, you can easily get one of the bones of an animal at the butcher's
shop, or you may find one in the fields.

~4. The Skeleton.~--All the bones of an animal, when placed properly
together, have nearly the shape of the body, and are called the
_skeleton_ (skel'-e-ton). The skeleton forms the framework of the body,
just as the heavy timbers of a house form its framework. It supports all
the parts.

~5. The Skull.~--The bony part of the head is called the _skull_. In the
skull is a hollow place or chamber. You know that a rich man often has a
strong room or box in his fine house, in which to keep his gold and
other valuable things. The chamber in the skull is the strong-room of
the body. It has strong, tough walls of bone, and contains the _brain_.
The brain is the most important, and also the most tender and delicate
organ in the whole body. This is why it is so carefully guarded from
in
