CHAPTER XXV.
HOW WE HEAR, SEE, SMELL, TASTE, AND FEEL.
~1.

The Senses.~--We have five senses--_hearing_, _seeing_, _smelling_, _tasting_, and _feeling_.

These are called special senses because they are very different from each other.

They also differ from the general sense of feeling by means of which we feel pain when any part is hurt.
~2.

Organs of the Special Senses.~--Each of the special senses has a special set of nerves and also special cells in the brain which have charge of them.
