First edition with half-title. pp. i-ii 1-3 4-254. 1 vols. 8vo. "I show that that one can only account for the movements of Uranus by introducing the perturbing action of a new planet" p. 5. French astronomer Urbain Le Verrier 1811-77 successfully predicted the location of an eighth solar planet now called Neptune. The seventh planet Uranus had been discovered telescopically in 1781 by William Herschel. Le Verrier demonstrated that the perturbations of the orbit of Uranus could be explained by the existence of a further celestial body and performed the mathematical calculations. The existence of the planet was confirmed by observation in September 1846 I.G. Galle writing to Le Verrier from Berlin "The planet whose position you communicated really exsts" p. 248. This book gathers four memoranda of "partial publications" read at the Academie des Sciences between November 1845 and October 1846 with a fifth part dated 5 October 1846. He notes that "this success permits us to hope that after thirty or forty years of observations of the new planet one will be able to use it in turn for the discovery of the planet after it in terms of distance from the Sun. And so on; sadly one will come upon bodies invisible by reason of their immense distance from the Sun but whose orbits will over centuries be charted with great exactness through the theory of secular inequalities" p. 254. "undeniably one of the major scientific events of the nineteenth century" Lequeux p. 22. Uncommon and with nice contemporary American provenance the original owner likely being Alexander Evans 1818-1888 engineer and attorney member of Congress from Maryland 1847-53 and an amateur astronomer who travelled to Illinois to observe the total eclipse in 1869. OCLC reports a dozen locations over several records most in France. For Le Verrier see James Lequeux Le Verrier-Magnificent and Detestable Astronomer Springer 2013 Bachelier, Imprimeur-Libraire ...

First printing of Le Verrier's importent and famous papers predicting and confirming the discovery of the Planet Neptune including the "preparatory" paper the first paper on the anomalities in the orbit of Uranus the calculations on which eventually leading to his prediction and discovery of a new planet Neptune the following year 1846."In 1846 John Cauch Adams. and Urban J. Leverrier. simultaneously and independently determined the location of a possible new planet. In 1845 he wrote of his findings of the mathematical location of a new planet to Sir George Bidell Airy Because Adams was unknown his letter was put aside. Meanwhile the same perturbations of Uranus had become of interest to Leverrier. On July 1should be June ! 1846 he presented a paper "Recherches sur les mouvements d'Uranus" to the Academie des Sciences inParis. When Airy realized that Leverrier and Adams had reached the same conclusions he hastened to suggest that a search be made for the newplanert. Shortly hereafter it was seen bur not recognized. About a week before it was found in England it was discovered by Galle in Berlin on information supplied by Leverrier. Thus the honour of the discovery or even co-discovery of the new planet Neptune was lost to Adams and credited to Leverrier. Adams paper was reade before the Royal Astronomical Society November 13 1846 and was published in 1847. Milestones p. 40.Milestones of Science No 132. - Dibner No. 16. unknown
