Paris, Imprimerie Nationale, 1903-1909. In six volumes, including the supplement. Large 4to (29.5 x 22.6 cm). 3,908 [ix, 3,899] pp.; 39 mainly geological folded maps or profiles (six in full-colour), and heliogravures (photogravures), some with printed overlays. Uniform contemporary half calf over marbled boards. Spines with four raised bands and gilt title.
A very good set of the largest monograph ever published on the geology of the Pyrénées, and the main work of the French geologist Léon [Louis Hippolyte] Carez (1854-1932). Published in the Mémoires pour servir à l'explication de la Carte géologique détaillée de la France and arguably its main contribution to Pyrenean geology. Very well illustrated, and with a very large bibliography. Page numbering is consecutive. The supplement includes a long list of errata. A few spine ends slightly frayed, and with a small damp stain in the lower inner gutter of one volume, otherwise a very good, complete set. Rare. We have seen no other copies on the market this century. Cat. BM(NH) 6, p. 183.
