Two geographical diagrams showing the distribution of animals around the world, and the second shows the distribution of birds and reptiles, the various species being represented by the coloured lines. From a selection of 44 scientific teaching diagrams, drawn and engraved by John Emslie on geology, geography, astronomy and natural philosophy. 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.
