William Smith's rare geological survey of Sussex.

Smith produced the first geological map of England and Wales in 1815, titled A Delineation of the Strata of England and Wales, with Part of Scotland. This was the first geological map of an entire country, systematically created using Smith's principle of faunal succession, which correlated rock layers based on their fossil content, which contained “an amazing amount of correct detail” (DSB) and was the basis for all the geological maps that followed. In 1819, he began the publication of a geological atlas of England and Wales. Containing twenty-one maps of various English counties, it was published in parts over five years, but remained unfinished. The map is a reissue of Cary’s map of 1801, with the addition of the geological information.
