viii PREFACE TO THE FIRST EDITION.

with transient phenomena by the inspection, of their record on the
"photographic film of the oscillograph. I would therefore recom-
mend the reading of the following pages as an introduction to
the study of " Transient Phenomena/' as the knowledge* gained
thereby of the physical nature materially assists in the under-
standing of their mathematical representation, which latter
obviously is necessary for their numerical calculation and pre-
determination.

The book contains a series of lectures on electric discharges,
waves, and impulses, which was given during the last winter to
the graduate classes of Union University an an elementary intro-
duction to and "translation from mathematics into English*¹ of the
•" Theory and Calculation of Transient Electric Phenomena and
Oscillations.⁷⁷ Hereto has been added a chapter on the calculation
of capacities and inductances of conductors, since capacity and
inductance are the fundamental quantities on which the
depend.

In the preparation of the work, I have been materially
by Mr. C. M. Davis, M.E.E,, who kindly corrected and edited
the manuscript and illustrations, and to whom I wish to
my thanks,

CHARLES PROTEUS STEINMISTSS.
