DR. FLEMING’S reputation as inventor, experimenter, theorist, and expositor in the domain of wireless telegraphy is so high that any work by him upon this fascinating and difficult subject will be welcome. We already have learned to look to his advanced and mathematical works for guidance when seeking to understand the intricacies of spark or æthereal telegraphy. In the present book, however, Dr. Fleming has undertaken a task which in many ways is more difficult than writing an advanced treatise, for he has attempted, and his success is great, to unfold the nature of the operations on which this new art depends without the use of mathematical or very technical language. This book is to be considered as a continuation of, or addition to, “Waves and Ripples in Water, Air, and Æther,” by the same author.
