and Family Dictionary, a much more full and
comprehensive abridgment than we have before offered. The other books
in the series have also been most carefully revised, and the new
abridgments prepared, by and under the direction of Prof. C. E.
Goodrich and Mr. Wm. G. Webster, with assistance from other most
competent sources, no pains having been spared to remove any, however
slight, grounds for reasonable objection which may have existed to the
books in the old form, and to render them as nearly perfect as
possible, and yet more worthy the high position they occupy as the

STANDARD DICTIONARIES OF THE ENGLISH LANGUAGE,

proved to be such by a sale many times greater than that of all other
dictionaries published in America combined, and acknowledged such by
our Courts of Justice, as well as the people at large.

The old stereotype plates having been much worn by the immense numbers
of books printed from them, the occasion has been embraced to make the
very thorough revision and improvement now completed. All the books in
the series are now printed, therefore, on

ENTIRELY NEW ELECTROTYPE PLATES,

and are uniform in Definitions, Orthography, Orthoepy, &c.

It is deemed unnecessary to enlarge upon the claims of these well-known
standard works. _Literally thousands_ of testimonials to their
superiority to all others are in the hands of the publishers, from the
most eminent educational and literary men in all parts of the country.
From year to year their sale is steadily and rapidly increasing. It is
believed that the mere _increase_ in the sale of these abridgments the
present year, will be greater than the entire combined sale of all
other American Dictionaries.
