the body, and those which enable us to move. In the top of 
“the skeleton we see the bones of the head, called the cranium 
or skull. 
THE SKULL. . 
This is composed of eight small bones, all very nicely 
~ fitted and dove-tailed together like the sides of a box. The 
place where the bones join are called sutures. In the little 
infant the bones are soft and do not unite until it is several 
months, and sometimes several years old. The‘human skull, 
being of an oval shape, it does not feel the force of blowsso 
much as it woyld if it had any other shape. As the child ‘ 
becomes older, the bones are firmer and stronger, and give 
more support. The skull contains the brain, which I may 
tell you about at some future time. It is very important 
that it should be guarded and well taken care of, as we find 
it is by its hard ~~ firm covering.
