Spons' dictionary of engineering, civil, mechanical, military, and naval; with technical terms in French, German, Italian, and Spanish
Spons' dictionary of engineering is an 1871 London and New York reference work by Edward Spon, Oliver Byrne and Ernest Spon, compiled for engineers and technical readers across civil, mechanical, military and naval fields with terms given in several languages. Its pictures are numbered line drawings of machines, frames and mechanisms in plain black outline on cream paper, with lettered callouts; a designer could borrow their clean diagrammatic structure, labelled schematic style and precise linework for technical graphics.
