EXPERIMENTAL SCIENCE
BY
GEORGE M. HOPKINS


Seventeenth Edition Revised and Enlarged. 840 Pages, 800 Illustrations.
Price by mail, cloth, $4.00; half morocco, $5.00.


This book treats of various topics of physics in a popular and practical way, describing the apparatus in detail and explaining the experiments in full so that those interested in physics can make the apparatus at small expense and perform the experiments without difficulty. The subject is not treated from the mathematical side, and thereby its field of usefulness to a very large number is increased. This book should not be confounded with books which give hackneyed experiments and illustrations. Nearly all of the experiments are new or are performed in a new way. The illustrations cost $10,000. It is impossible to give even an outline of the book in the present advertisement, but the publishers will send a four-page circular giving samples of the illustrations and a full table of contents on request.
