Über Kathoden-, Kanal-, Röntgen- und Becquerelstrahlen
A short German physics monograph by Franz Leininger on cathode, canal, X- and Becquerel rays, printed by H. Stürtz in Würzburg in 1905 for students and researchers in radiation physics. The plates are spare line diagrams on tinted paper: discharge tubes in profile with lettered electrodes, a plan of a shielded room with arrowed ray paths, and fans of curved particle trajectories deflected into arcs, useful as schematic apparatus outlines, arrow-and-vector motifs, and labelled technical line art.
