PREFACE.


The present work is in some respects a sequel to the PIONEERS OF
ELECTRICITY, and it deals with the lives and principal achievements of
those distinguished men to whom we are indebted for the introduction
of the electric telegraph and telephone, as well as other marvels of
electric science.
