"Contains a clear and concise account of the various forms in which electricity is used at the present day, and the working of the telephone, wireless telegraphy, tramcars, and dynamos is explained with the greatest possible lucidity, while the marvels of the X-rays and of radium receive their due notice. Now that electricity plays such an all-important part in our daily life, such a book as this should be in the hands of every boy. Indeed, older people would learn much from its pages. For instance, how few people could explain the principles of wireless telegraphy in a few words if suddenly questioned on the subject. The book is well and appropriately illustrated."--_Graphic._ "Mr. Gibson sets out to describe in non-technical language the marvellous discoveries and adaptation of this pervasive and powerful essence, and being a most thorough master of the subject, he leads the reader through its mazes with a sure hand. Throughout he preserves a clear and authoritative style of exposition which will be understood by any intelligent reader."--_Yorkshire Observer._ "A popular and eminently readable manual for those interested in electrical appliances. It describes in simple and non-technical language what is known about electricity and many of its interesting applications. There are a number of capital illustrations and diagrams which will help the reader greatly in the study of the book."--_Record._ SEELEY & CO., LTD., 38 GREAT RUSSELL STREET.
