Diagrams of machines from a series called 'Illustrations of Natural Philosophy' drawn and engraved by John Emslie. This hand-coloured engraved plate is taken from a series published and probably written by James Reynolds of 174 Strand in London in 1850-1860 in response to the popular demand for information on the developments taking place in science and engineering as a result of the Industrial Revolution. Superbly illustrated images with a related text were presented loose in a portfolio so that they could be pased around a clas or lecture room or used as posters.
