=Example= is another method of amplifying a definition or of expounding an idea more fully. The following sentences immediately succeed Mr.Bates's definition and contrast just quoted:
A good deal which we are accustomed in exactly to call description is really exposition. Suppose that your small boy wishes to know how an engine works, and should say: "Please describe the steam-engine to me." If you insist on taking his words literally--and are willing to run the risk of his indignation at being wilfully misunderstood--you will to the best of your ability picture to him this familiarly wonderful machine. If you explain it to him, you are not describing but expounding it.
