e necessary to revise
the work again, Professor Lindsay, of Dickinson College, was
selected to assist Dr. Storer in the work. The present edition has
been entirely rewritten by them, following throughout the same plan
and arrangement of the previous editions, which have been so highly
approved by a generation of scholars and teachers.

"If a book, like an individual, has a history, certainly the record
of this one, covering a period of nearly thirty years, is of the
highest and most honorable character."--_From The American Journal
of Science._
