London, The Geological Society [Taylor and Francis], 1861. 8vo (22.2 x 14.0 cm). 84 pp.; two hand-coloured maps; one very long, multi-folded profile, and three lithographed plates showing fossils. Original printed wrappers.
A rare offprint. The work is based on the research of geologist, mineralogist and Darwin-correspondent David Forbes (1828-1876), brother of the zoologist (principally malacologist), marine biologist, botanist and zoogeographer Edward Forbes (1825-1854). David Forbes travelled through the Andean regions of Bolivia, Peru and Chile between 1857 and 1860, collecting numerous fossils and making lengthy notes on the geography, palaeontology and geology of the region. One profile is over 140 cm wide; another – hand-coloured – shows the development of the knowledge of the earth layers from D'Orbigny in 1842 to Pissis (1856) to Forbes (1860). The contribution by Thomas Henry Huxley is one of his earliest. Two lithographic plates depicting marine fossils are by the artist, malacologist and publisher George Brettingham Sowerby II (1812-1884). Two old stamps on the front wrapper, edges a bit frayed; small part of the cover of spine ends perished; internally very good, clean. Neither in Cat. BM(NH) nor in Sabin.
