APPLETONS'

SCIENCE TEXT-BOOKS.

D. Appleton & Co. have the pleasure of announcing that
in response to the growing interest in the study of the
Natural Sciences, and a demand for improved text-books
representing the more accurate phases of scientific
knowledge, and the present active and widening field of
investigation, they have made arrangements for the
publication of a series of text-books to cover the
whole field of science-study in High Schools,
Academies, and all schools of similar grade.

The author in each separate department has been
selected with regard to his especial fitness for the
work, and each volume has been prepared with an
especial reference to its practical availability for
class use and class study in schools. No abridgment of
labor or expense has been permitted in the effort to
make this series worthy to stand at the head of all
educational publications of this kind. Although the
various books have been projected with a view to a
comprehensive and harmonious series, each volume will
be wholly independent of the others, and complete in
itself.
