Folio. Bound in an attractive modern half calf and marbled boards binding. Large folding map, mounted on three pieces of linen, housed in matching half calf fold over box. Numerous plates, many folding and coloured. Internally clean. A wonderfully bound copy of a foundational geological text. Very scarce. A landmark in the history of geology, presenting, for the first time, the succession of fossils below the Old Red Sandstone and thus opening up a diverse "new" epoch of fossil discoveries unlike those seen before. This monograph allowed for the dating of fossiliferous strata much earlier than the Old Red Sandstone and enhanced the scientific understanding of early animal life, even playing an important role in the debate of the genesis of life itself (Beverley 179) A pretty copy.
