THE BRAIN AND ITS WORK.
The brain is egg-shaped, and of two parts, the large brain (_cerebrum_),
and the little brain (_cerebellum_). These are composed of a white and gray
substance, which in the large brain is so folded and wrinkled that it looks
like the meat of an English walnut; in the little brain it is so arranged
that it resembles a tree, and is called _arbor vitae_, tree of life. The
mind does its thinking through the large brain, and controls its muscles
through the little brain.
