KiPP'S "ALTERNATING CURRENTS OF ELECTRICITY."

Published by The W. J. Johnston Co.
 

The author has succeeded in producing a really practical book,
covering the most important parts of the subject of alternating cur¬
rents, induing the latest developments in this branch of electricity.
The discussion is always attractive, and is made clear without the aid
of complicated mathematical processes. The books appeals not only
to practical men but also to those who may be more largely in¬
terested in the theoretical side of the subject.
