This map, based on Arrowsmith's work was published by Charles Knight & Co. between 1849 and 1852 and was included in one or both of two atlases to be published during those years. Knight had published the same map in 1844 for his Map of the Society for the Diffusion of Useful Knowledge. However, this was a different plate and the first edition of the map. Between 1849 and 1852, Knight had a new plate made, the one described here. In this state the map went through several revisions and publications up to 1877. The original map was first published in 1837.
See H3/1100/1834 for the first edition and notes concerning the evolution of the maps. See also: A/1100/[1844]; A/1100/1853; A/1100/[1877]
