It should be of interest to anyone who wants to learn about the early days of radio, both amateur and professional. From an ad for the original book Lessons in Wireless Telegraphy. (WRITTEN SO THAT YOU CAN UNDERSTAND THEM) Our new book contains a systematic elementary course in the principles of Wireless Telegraphy and the electrical laws upon which it depends. It contains more reliable and practical information than any other book of its kind. IF YOU OWN A WIRELESS OUTFIT it will give you a thorough grounding in the principles and care of the efficiency of your apparatus. IF YOU INTEND PURCHASING OR OPERATING WIRELESS TELEGRAPH APPARATUS you could not desire a more complete or concise explanation of matters it is essential to understand. IF YOU ARE A LAYMAN the book will prove valuable and interesting. It is something that you can well afford to read for it will give you a clear conception of one of the greatest wonders of the age. The book is divided into thirty lessons, each lesson dealing with a separate subject and following in a logical order so that repetition and possibility of confusion are completely avoided. It is profusely illustrated with perspective drawings and diagrams, each being carefully keyed so that parts may be readily discerned. It not alone describes the actual workings and construction of the instruments that go to make up a wireless station in sufficient detail to prove of great value to the experienced student but treats the subject in such a manner that even the beginner will have no trouble to clearly grasp the matter. Among the lists of contents may be mentioned a careful discussion and explanation of such subjects as the "why and the wherefore" of Magnetism, Magnetic Induction, Primary Cells, Storage Batteries, the Dynamo, the Alternator, the Motor Generator, the Induction Coil, the Transformer, the Condenser, Volts, Amperes, Watts, Coulombs, Ohm's Law, Electric Waves, the Ether, Oscillations, the Aerial, Spark Gaps, Quenched Gaps, Rotary Gaps, Helixes, Coupling, Tuning, Detectors, Tuning Coils, Loose Couplers, Variometers, Condensers, Hot Wire Ammeters, Circuits and Diagrams, etc., etc., etc. Each subject is discussed in detail and in all its branches. For instance, the lesson dealing with aerials describes vertical aerials, pyramid aerials, flat top aerials, umbrella aerials, loop aerials, etc., and peculiarities or advantages. The lesson on detectors deals with Electrolytic, Perikon, Silicon, Pyron, Carborundum, Magnetic and Audion Detectors, etc. The lesson on the theory and arrangement of circuits will be found invaluable.
