These matters, as well as the simultaneous calculation of the place of Neptune by Adams and Leverrier, and its actual discovery by Galle, are set forth by Sir Oliver Lodge in a manner as charming for simplicity as it is valuable in its summary of scientific learning.

Owing to the great mass of these "giant planets," the inequalities of their motion, especially in the case of Saturn, affected by the attraction of Jupiter, is greater than in the case of the other planets. Leverrier failed to attain the necessary exactness in his investigation of their motion. Hill had done some work on the subject at his home in Nyack Turnpike before I took charge of the office.
Two systems of computing planetary perturbations had been used, one by Leverrier, while the other was invented by Hansen. The former method was, in principle, of great simplicity, while the latter seemed to be very complex and even clumsy.
Among my most interesting callers was Professor John C. Adams, of whom I have spoken as sharing with Leverrier the honor of having computed the position of the planet Neptune before its existence was otherwise known.
With such high recommendations, M. Leverrier requested from M. Rouland, the Minister of Public Instruction, the decoration of the Legion of Honour for M. Lescarbault. The Minister, in a brief but interesting statement of his claim, communicated this request to the Emperor, who, by a decree dated January 25, conferred upon the village astronomer the honours so justly due to him.
It was rash in a former subordinate to impugn the verdict of the chief of the Paris Observatory on a matter belonging to that special department of astronomy which an observatory chief might be expected to understand thoroughly. Accordingly, very little attention was paid by Leverrier to Liais's objections. Yet, in some respects, what M. Liais had to say was very much to the point.
It is strange but true that Dr. Finsen had never seen a smallpox patient at that time, but he knew the nature of the disease, and that the sufferer was affected by its eruption first and worst on the face and hands that is to say, on the parts of the body exposed to the light and he was as sure of his ground as was Leverrier when, fifty years before, he bade his fellow astronomers look in a particular spot of the heavens for an unknown planet that disturbed the movements of Uranus.
The work of the two men was prosecuted at almost the same time, but adopting the principle that priority of publication should be the sole basis of credit, Arago had declared that no other name than that of Leverrier should even be mentioned in connection with the work.
It was the time when Adams and Leverrier were contending to which of them belonged the honor of the discovery of the planet Neptune, and each side had its strong partisans. Among Miss Mitchell's papers we find the following with reference to this subject: "... Adams, a graduate of Cambridge, made the calculations which showed how an unseen body must exist whose influences were felt by Uranus.
