Abstract

(1) THIS little book comprises introductions to the various sections of physics, including mechanics and astronomy. The treatment is almost entirely qualitative, as is to be expected in an elementary-school book. For such purposes it appears to have many good points. The statements of the fundamental principles are clear, the printing is excellent, and the diagrams with which the various experiments are profusely illustrated are very good, particularly those bearing on the movements of the heavenly bodies. Perhaps the order in which the subjects are taken is a little peculiar, the treatment of mechanics being given towards the end of the book. This would be a serious defect in a work of wider scope, in which quantitative measurements in electricity and magnetism were described; here, however, the order of the subjects is comparatively indifferent.
