1st Edition. FIRST EDITION of an important and consequential paper in which John Couch Adams announces new mathematical methods in dealing with the pertubations of the Moon, and in so doing corrects Laplace's famed 1788 memoir. Laplace studied the Moon's mean rate of motion relative to the stars; his work provided an explanation in terms of changes in the eccentricity of the Earth's orbit considering only the radial gravitational forces on the Moon from the Sun and Earth and had obtained close agreement with historical observational records. "Adams showed that Laplace's solution was incorrect. In particular, Laplace had ignored a variation in solar eccentricity that introduces into the differential equations for the moon's motion a series of additional terms" (DSB I, p. 54b). In other works, Adams paper showed that while tangential terms vanish in the first-order theory of Laplace, they became substantial when quadratic terms are admitted. Small terms integrated in time come to have large effects and Adams concluded that Plana had overestimated the secular acceleration by approximately 1.66 inches per century" (Wikipedia). Adams "paper caused a sharp scientific controversy, marked by angry chauvinism on the part of several French astronomers. Their attack stimulated a number of independent investigations of the subject, all of which confirmed Adams' results. The matter was definitely settles in his favor by 1861, but not without hard feelings" (DSB 54b). CONDITION & DETAILS: London: Richard Taylor and William Francis. Quarto.

First appearance of this importent paper by Adams, - famous for his co-discovery with Le Verrier, of Neptune in 1846 - in which he introduces new mathematical methods in dealing with the pertubations of the Moon, raising a sharp scientific controversy, and correcting Laplace's great memoir of 1788."He (Adams) was elected a fellow of Pembroke College in 1853, and shortly afterward he presented to the Royal Society a remarkable paper on the secular acceleration of the moon?s mean motion. This quantity was thought to have been definitively investigated by Pierre Simon de Laplace in 1788, but Adams showed that Laplace?s solution was incorrect. In particular, Laplace had ignored a variation in solar eccentricity that introduces into the differential equations for the moon?s motion a series of additional terms. Adams calculated the second term of the series, on which the secular acceleration depends, as 3771/64m4 the value computed from Laplace?s work was 2187/128 m4. The effect of the correction was to reduce the figure for the moon?s secular acceleration by about half, from 10?.58 to 5?.70.This paper caused a sharp scientific controversy, marked by angry chauvinism on the part of several French astronomers. Their attacks stimulated a number of independent investigations of the subject, all of which confirmed Adams? result.
