Description
5 geometric figures explaining that Jean Dominique Cassini’s method of finding the anomalies of planets, as outlined in ‘Nouvelle maniere gemoetrique et directe ade trouver les apogées, les Excentricitez, et les anomalies du mouvement des planetes’, Journal des Sçavans (2 September 1669 [N.S.]), 32-35, had actually been discovered by Seth Ward in his Examen astronomiae philolaicae.
Illustrations to ‘Some considerations of Mr. Nic. Mercator, concerning the geometrick and direct method of signior Cassini for finding the apogees, excentricities and anomalies of planets’ in Philosophical Transactions of the Royal Society, vol. 5, issue 57 (25 March 1670). The original letter containing these diagrams was shown at a meeting of the Royal Society 27 January 1670 and can be found in Early Letters of the Royal Society EL/C1/50.
