Wonders of light and of colour
A popular science primer on optics, light and colour, published anonymously in London in 1890 for general and young readers. The plates are line diagrams: convex and concave lenses shaded with stipple, dotted construction circles, ray paths with arrowheads, and lettered points, offering ready-made geometric marks, dotted arcs and hatched glass textures for diagrammatic layouts.
