Flame, electricity and the camera; man's progress from the first kindling of fire to the wireless telegraph and the photography of color
A popular history of technology by George Iles, published in New York by Doubleday & McClure in 1901 for general adult readers tracing fire, electricity and photography. Line and wash engravings show laboratory apparatus—lenses, coils, electromagnets, spinning discs, letter-keyed parts and dotted ray paths—giving designers clean diagrammatic machine forms, hatched shading textures and annotated mechanical details.
