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 1(should 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. …

(Paris, Imprimerie de Bachelier), 1843. 4to. No wrappers as extracted from "Journal de Mathématiques pures et appliquées.Publié par Joseph Liouville", tome VIII. Pp. 273-360. Clean and fine. First appearance of Le Verrier's provisional theory on the motion of Mercury, his studies of which eventually did much to demonstrate the validity of Einstein's Theory of Relativity. The planetary orbits should agree with the predictions of the General Theory of relativity, but as Einstein pointed out in his "Erklärung der Perihelbewegung des Merkurs aus der allgemeinen Relativitätstheorie" from 1915, the divergences predicted were too small to be observed, except in the case of the nearest planet Mercury, where the perihelion advance, according to the formula, reaches the value of 43" per 100 years, being in full agreement with the calculations of Le Verrier, who found this unexplained rest in the perihelion advance of Mercury per century, if the perturbations due to the other planets are deduced.- Einstein tells in a letter to a friend that for several days he was in a 'state of delirious joy' by this wonderful astronomical confirmation of his theory."Le Verrier first began to study Mercury on the suggestion of Arago in 1840. Astronomers realized that Mercury's perihelion (the point at which the orbit of a planet is closest to the sun) advanced along its orbit at a rate of 566 seconds per century. Le Verrier calculated that, even when taking into account the forces exerted by other planets in the solar system, there still existed a discrepancy between calculation and observation. Le Verrier's accurate calculations showed that the planet's perihelion.did indeed advance forty seconds of an arc per century more than could be accounted for by Newton's theory of gravitation, even after the minor pertubing effects of the other planets had been allowed for." (Asimov). - Le verrier published these findings in the present work, carefully as to the mass of the planet, comparison with other orbits of planets and their perihelia. At the time, Le Verrier put down the discrepancy to mis-observation or mis-calculation.- Sparrow, Milestones of Science No. 133.…
