Abstract
THIS little book is divided into fifteen chapters, each chapter consisting of three or four paragraphs of large print describing the historical development of the ionic valve, the principles on which it works, and the various types of valve that are now used in wireless telegraphy. The diagrams are clear, of large size, and not overcrowded with details. References are given to the original papers describing the various forms of valves and their developments. The book can be recommended to all who intend to take up the serious study of radio-telegraphy, as it will impress the main facts about the ionic valve on their minds.
