La Condamine embarked for Peru in 1735 with the purpose of measuring several degrees of meridian at the equator to settle the controversy between the Newtonians and the Cartesians over whether the earth was flattened or elongated at the poles. The geodetic measurements proved the validity of Newton's hypothesis, completely debunking the opposing theory by Cassini and Picard. La Condamine's notable zenith sector is illustrated on one of the plates and is described in the text. There is also an account of his important research on the pendulum. First edition. 4to; viii, 266pp, index. Engraved vignette on title and three engraved plates at rear, folding. Hardbound in full contemporary leather with raised bands, gilt tooling and titling on spine.

References: Sabin #38483.
