2443. Rebuses are a class of enigmas generally formed by the first, sometimes the first and last, letters of words, or of transpositions of letters, or additions to words. Dr. Johnson, how-over, represents Rebus to be a word represented by a picture. And putting the Doctor's definition and our own explanation together, the reader may glean a good conception of the nature of the Rebus. Example: -

The father of the Grecian Jove:

A little boy who's blind; The foremost land in all the world,

The mother of mankind; A poet whose love-sonnets are

Still very much admired; -The initial letters will declare

A blessing to the tired.

Answer - Saturn; Love; England Eve: Plutarch. The initials form sleep.
