Cassini, Herrn Jacob; Mathematische und genaue Abhandlung von der Figur und Grosso der Erde, wobey die bewundernswürdige Verlungerung der Mittagslinie des königlichen Observatorinm zu Paris durch ganz Frankreich von eiuem Ende desselben bis zum andern insbesondere dentlich beschrieben und vorgestellet wird von —. Ihres vielfältigen Nutzen wegen, so in Ausübung der Geometrie, Trigonometrie, Aetronomio und Geographie daraus zu erlangen stehet, aus dem französischen Original in die tentsche Sprache treulich übersetzet, zum Druck befördert und mit eiuer Vorrede statt eiuer Eiuleitung zu mehren Verständnias des ganzen Wercks begleitet von Johann Albrecht Klimmen. Leipzig & Zürich, 1741. Octavo, pp. xl, 416, engraved frontispiece and 7 engraved folding plates.
The work is complete and in a period calf with gilt spine titles and panels. The binding is tight and clean, the text and plates are clean with very minor foxing. In very good condition.
Jacques Cassini (8 February 1677 – 16 April 1756) was a French astronomer and son of the famous Italian astronomer Giovanni Domenico Cassini.
Cassini was born at the Paris Observatory. Admitted at the age of seventeen to membership of the French Academy of Sciences, and elected in 1696 a fellow of the Royal Society of London. He succeeded his father's position at the observatory in 1712. Cassini undertook the measurement of the Paris meridian north to Dunkerque in 1718. He published the results, which supported his theory of elongation at the poles, in “De la grandeur et de la figure de la Terre” in 1722. In an attempt to gain further evidence to support his case for an elongation of the poles, Cassini organised another project in 1733, this time to measure the perpendicular to the meridian from Saint-Malo to Strasbourg.
