These are actually matching maps that together describe the geology of Great Britain. The first map is the northern sheet which carries the full title in a panel with engraved vignettes of skeletons, fossils, and the head of a Saber-toothed Tiger. The lower sheet contains the legend which identifies an amazing 25 different formations. To the sides of the legend are numerous fossil Ammonites. Both sheets are filled with notations and tables. The maps are from the Sketches and Notes of Professor Edward Forbes, F.R.S., President of the Royal Geological Society. Surrounded by a keyboard-style border.
Minor offsetting with short centerfold separations at bottom of each sheet, just passing the neatline on Sheet No. 2.
