his interesting achievements in this field; the famous London lecture
published in this volume is a proof in itself. His first lecture on
his researches in this new branch of electricity, which he may be said
to have created, was delivered before the American Institute of
Electrical Engineers on May 20, 1891, and remains one of the most
interesting papers read before that society. It will be found
reprinted in full in _The Electrical World_, July 11, 1891. Its
publication excited such interest abroad that he received numerous
requests from English and French electrical engineers and scientists
to repeat it in those countries, the result of which has been the
interesting lecture published in this volume.
The present lecture presupposes a knowledge of the former, but it may
be read and understood by any one even though he has not read the
earlier one. It forms a sort of continuation of the latter, and
includes chiefly the results of his researches since that time.
EXPERIMENTS WITH ALTERNATE CURRENTS OF HIGH POTENTIAL AND HIGH FREQUENCY
I cannot find words to express how deeply I feel the honor of
addressing some of the foremost thinkers of the present time, and so
many able scientific men, engineers and electricians, of the country
greatest in scientific achievements.
The results which I have the honor to present before such a gathering
I cannot call my own. There are among you not a few who can lay better
claim than myself on any feature of merit which this work may contain.
I need not mention many names which are world-known--names of those
among you who are recognized as the leaders in this enchanting
science; but one, at least, I must mention--a name which could not be
omitted in a demonstration of this kind. It is a name associated with
the most beautiful invention ever made: it is Crookes!
When I was at college, a good time ago, I read, in a translation (for
then I was not familiar with your magnificent language), the
