Electricity treated experimentally
A school physics textbook by Linnæus Cumming, published in New York by D. Van Nostrand in 1887, teaching electricity to students through bench experiments. The 203 figures are line and wood-engraved diagrams of apparatus on stands, coils, spheres, wire circuits and battery cells, with letter labels and hatched shading, useful as technical diagram motifs or lettered schematic details.
