Geological Map of Scotland, 1865. Murchison and Geikie.
Geological Map of Scotland, 1865. Murchison and Geikie. Scale 1:1,500,000 (1inch = 25 miles approx.) Colour printed, 43 x 23 cm., folded and tipped into a red hard cover book-style folder, 22 x 15 cm, with the explanatory booklet. The booklet, First Sketch of a New Geological Map of Scotland with Explanatory Notes, is dated 1862, while the map is ‘revised up to January, 1865’. This map is rare and shows Murchison’s mistaken Silurian interpretation of much of the north of Scotland, subsequently and posthumously withdrawn. In good to very good condition.
