Les rayons X et la photographie a travers les corps opaques
A French technical account of X-rays and radiography by physicist Charles-Edouard Guillaume, published in Paris by Gauthier-Villars in 1896, months after Röntgen's discovery, for scientists and photographers. Line diagrams show Crookes and focus tubes, coils, screens and bench setups in plain outline, alongside halftone radiographs of hands, coins and objects sealed in boxes.
