One of a selection of 44 scientific teaching diagrams, drawn and engraved by John Emslie on geology, geography, astronomy and natural philosophy with a chart showing the geological section of the earth's crust. The map also has notes and diagrams illustrating fosil remains and coal works beneath the sea. 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.
