With Murchison some of his earliest work was done on the complicated regions of the schists of the Scottish Highlands; and the small geological map of Scotland published in 1862 was their joint work: a larger map was issued by Geikie in 1892.
In 1865 Geikie's Scenery of Scotland (3rd edition, 1901) was published, which was, he claimed, the first attempt to elucidate in some detail the history of the topography of a country.
