Abstract
WE have already had occasion to review in these columns Dr. Fleming's treatise on “The Principles of Electric Wave Telegraphy,” and at the time we expressed the opinion that that treatise not only admirably filled a gap in the literature of the subject, but deserved to rank as the most important, if not the only, book on wireless telegraphy which students need consult. It must be frankly admitted, however, that by writing the present manual Dr. Fleming has performed another service to this branch of electrotechnology, in the exposition of which he stands, certainly in this country and probably in any country, easily first. The former treatise was possibly too exhaustive and in parts too difficult for those who had not the ability or inclination to study the subject thoroughly. It must be remembered that wireless telegraphy has become in recent years a department of applied electricity of great practical importance, offering a steadily increasing field of mployment for large numbers of men. The majority of those who are engaged or who seek engagement in this work are hardly to be expected to have any desire to pursue its study into its more difficult theoretical parts; to such the present volume will prove an adequate guide. To others it will serve as a useful introduction to its more comprehensive predecessor.
