The object of the work is to afford to the student, the artisan, the mechanic, and in fact all who are interested in science, whether young or advanced in years, a ready means of acquiring a general knowledge of physics by the experimental method.

The leading principles of physics are illustrated by simple and inexpensive experiments and the endeavor has been made to make the explanations of both apparatus and experiment plain and easily understood. In the new edition, the scope of the work has been broadened and presents the more recent developments in modern science.

An illustrated circular and complete table of contents sent free on application.
