Contributions to geology.

Philadelphia, PA, Carey, Lea and Blanchard, 1833. 8vo (23.8 x 14.5 cm). vii, 227 pp.; six engraved, finely hand-coloured plates. Mid-20th-century black buckram with gilt title on the spine. = A seldom-seen publication by the American malacologist and palaeontologist Isaac Lea (1792-1886), consisting of four separate works, viz., Tertiary formations of Alabama (with Supplement), (178, 22 pp.), New Tertiary fossil shells from Maryland and New Jersey (8 pp.), New genus of fossil shell from New Jersey (4 pp.), and Tufaceous lacustrine formation of Syracuse, Onondaga County, New York (7 pp.). Together they form the nucleus of Lea's palaeontological publications, and of his marine publications. Nearly all his other writings were devoted to Recent freshwater and land molluscs. The illustrations, by J. Drayton, are excellent. Provenance: Harvard University Library, with their bookplate and "discarded" stamp on the front pastedown, and weak blind-stamp on the title. Small pictorial, palaeontological bookplate of Jeffrey Darl Stilwell mounted on the rear pastedown. Some light, mostly marginal spotting to a few text leaves, the plates clean, except for one caption, added in an old hand. A very good copy. Not in Nissen ZBI.
