BY THOMAS KEITH.

THE NINTH EDITION.

Arithmetic is the easiest, and consequently the first sort of abstract rea-

soning which the mind commonly bears, or accustoms itself to, and is
of such general use in all parts of life and business, that scarce any
thing is to be done without it.-LOCKE ON EDUCATION.
