Roentgen Rays and Phenomena of the Anode and Cathode.

This volume offers a clear, experiment‑driven introduction to the radiant energy that emerges from electric discharge tubes—the very source of X‑rays. Drawing on the work of pioneers such as Faraday, Crookes, Lenard and J. J. Thomson, the author weaves together historical milestones with modern explanations, all supported by sixty detailed diagrams and half‑tone illustrations. Readers will follow the development of key ideas, from the early observations of cathode and anode behavior to the first practical uses of Roentgen rays.

The book is organized with numbered paragraphs and cross‑references, making it easy to trace connections between experiments and theory. Designed for students and curious science enthusiasts, it presents each experiment in a concise format: the apparatus, the result, and the inferences drawn by the investigators. Along the way, practical applications and theoretical insights are highlighted, providing a solid foundation for anyone wanting to understand the early days of X‑ray physics.
