First edition of the most important work to issue from the Peruvian expedition of 1735-1744, undertaken by the Royal Academy with the goal of measuring an arc of the meridian near the equator, resulting in the determination of the shape of the earth as an oblate spheroid. Bouguer quarrelled with his fellow scientists on the expedition, La Condamine and Godin, and thus published his own report separately. - Sabin 6875; Norman 285.€ 750
