John Cuthbertson's Abhandlung von der Elektrizität nebst einer genauen Beschreibung der dahingehörigen Werkzeuge und Versuche : ; Beschreibung einer verbesserten Luftpumpe
A German-language treatise on electricity by John Cuthbertson, published in 1786 by the Schwickert publishing house, with a description of an improved air pump, written for scientists and instrument makers. Its plates are engraved line drawings of electrical apparatus: glass globes and cylinders on stands, pulleys, leyden jars, and balanced rods with wires and small spheres, drawn in plain technical detail that suits diagrams, schematic rules and vintage scientific instrument motifs.
