Excerpt from Wireless Telegraphy: Its Origins, Development, Inventions, and Apparatus
The aim of this book is to present a comprehensive view of wireless telegraphy, its history, principles, systems, and possibilities in theory and practice. In considering inventions controversy has been avoided, although the claims of individual inventors have been carefully defined. Because of the complexity of the subject a certain amount of allusion in one part, to matters dealt with in another, has been inevitable; but it is hoped that such repetition may prove helpful to the reader. The book itself is designed to be of use both to the general public and to the technical student.
The author begs to acknowledge to the publishers his obligation for kind co-operation ; to the Century Magazine for extracts from the article by Mr. McGrath of St. Johns; and to the Scientific American for extracts and diagrams from an article by Mr. A. F. Collins.
