Description GÃ©ologique des Environs de - CUVIER, Georges & BRONGNIART, Alexan - 1822. 
16 lithographed plates (one folding) & two hand-colored engraved maps (one of which is very large & folding). 3 p.l., viii, 2, 5-428 pp. Large 4to, cont. marbled boards (small defect towards head of spine), green leather lettering piece on spine. Paris: G. Dufour & E. d'Ocagne, 1822. New edition, a rewritten and greatly expanded version of Cuvier and Brongniart's GÃ©ographie MinÃ©ralogique des Environs de Paris (1808 & 1811). This geological classic extended geological time, showed an alteration between marine and fresh water conditions, and demonstrated the value of precisely collected and identified fossils as criteria for tracing a detailed series of strata. Brongniart, with the assistance of Cuvier, "drew up a systematic table of the succession of stratigraphical horizons in accordance primarily with the sequence of the deposits of the ground, and with the particular fossils characterising each group of deposits."-Zittel, p. 104. Of the nine formations Cuvier and Brongniart identified, only two were known in Werner's system. This edition contains for the first time Brongniart's descriptions of strata from many different parts of Europe. This additional evidence led him to stress the primacy of fossil evidence over that of lithology as a criterion for age, wherever the two sources of evidence were found to conflict. Apart from the minor binding defect, a fine, crisp, and large copy. The folding plate has a clean tear in a fold without loss. ? D.S.B., II, p. 493-97. Zittel, pp. 104-06.
