One of a set of teaching cards published by James Reynolds & Sons, London, England around 1851. Titled 'The Distribution of the Human Race', the chart was drawn and engraved by John Emslie. The map shows the population density around the world along with the ethnographic racial groups then recognised. The basis of these divisions is illustrated in a separate diagram showing the skull forms of different races. A smaller inset map also outlines the global distribution of the world's various religions.
