Mesure des trois premiers degrés du méridien dans l'hémisphere austral : tirée des observations de mrs. de l'Académie royale des sciences, envoyés par le roi sous l'équateur
A 1751 Paris royal printing house publication by Charles-Marie de La Condamine and the Académie royale des sciences, recording the French geodetic expedition sent to the equator to measure degrees of the meridian in the southern hemisphere, written for scientists and surveyors. The plates show engraved meridian maps with triangulation chains, a surveying instrument on a tripod stand, and a cross-section profile of the Quito meridian, drawn in fine black line with clean lettering that suggests a precise technical diagram style.
