Taschenbuch für Mathematik und Physik
A German pocket handbook of mathematics and physics by Rudolf Wolf, printed and published by Fr. Haller in 1856, held by the ETH-Bibliothek. Its pictures are small black-and-white geometric diagrams numbered as figures, with labelled points, lines and angles, astronomical sphere and horizon drawings, and solid figures, which a designer might use as sources for technical line-drawing and labelled schematic motifs.
