Researches on diamagnetism and magne-crystallic action : including the question of diamagnetic polarity
A collected volume of John Tyndall's experimental papers on diamagnetism and magne-crystallic action, published by Longmans, Green in London in 1870 for physicists and scientific readers. The 39 figures are small wood-engraved apparatus diagrams: cylindrical coils and bar specimens suspended between hatched magnet poles marked N and S, with arrows for rotation, offering hatching textures, labelled polarity conventions, and compact diagram framing.
