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.
