The successful firm of W. & A. K. Johnston was founded by Sir William Johnston (1802-88) and was based in Edinburgh from 1825. The following year he was joined by his brother Alexander Keith Johnston. The ‘Physical Atlas’ offered here is the ‘first British atlas to give a synoptic view of physical geography’ (Tooley). It is arranged under Geology 10 maps, Hydrology 6 maps, Meteorology 5 and Phytology and Zoology 9. As the title states it is based on Berghaus’ ‘Physikalischer Atlas’.
