Discoveries and inventions of the nineteenth century
A popular survey of nineteenth-century technology by Robert Routledge, published in London by George Routledge and Sons in 1905 for general readers and students. The 444 wood-engraved figures mix hatched sectional diagrams of machinery, small apparatus sketches on blank grounds, and tonal interior views of laboratories and works — useful for cutaway line work, numbered part labels, and industrial scenes.
