Detailed geological map of England and Wales.

A particularly attractive map with much of the geological information based on the earlier work of Smith, MacCulloch, Greenough and Smith's nephew John Phillips. The map has cross sections and notes referring to mineral deposits which were vital, at that period, for the industries and wealth of the country.

State 3: the map has been heavily re-engraved. The original title has been erased and re-engraved in the north sea, together with a key to the railways and canals. Above the title the explanation of the colouring has been re-engraved, with the map now extending as far as Forfar.
