Following Nikola Tesla On His Work With Alternating Currents. This book is the second in the four part Tesla Presents series containing previously unavailable material on the pioneering work of Nikola Tesla in field of radio frequency electrical engineering. While first delivered under the title "On the Streams of Lenard and Roentgen with Novel Apparatus for Their Use" the information presented in the lecture goes far beyond this topic. In addition to his opening remarks on X-ray discovery, a major portion of Tesla's commentary deals with the high power radio-frequency resonant power supplies of his own design, used in conjunction with his work. There are also clear descriptions of electro-mechanical stroboscopic instruments that Tesla designed for the measurement of frequency and phase. Other topics include wireless receiving methods and the genesis of Tesla's 1937 particle beam tube. During the talk Tesla had displayed approximately 120 drawings of specially constructed vacuum tubes, many being of the Lenard type and also the single-electrode type of his own design. Among the drawings are tubes used in his wireless communications experiments. Enhanced photographs of these images are among the 32 illustrations which fill out this fine addition to the Tesla cannon.
