Cambridge Observatory; but when his result was announced there was noise enough and to spare. He was always fond of star-gazing and speculation, and is already on the watch for another planet. Burnard told us that when Professor Adams came from Cambridge to visit his relatives in Cornwall he was employed to sell sheep for his father at a fair. He is a most good son and neighbour, and watchful in the performance of small acts of thoughtful kindness." "1863, July 2nd.--Have just returned from a visit to Professor Adams at Cambridge. He is so delightful in the intervals of business, enjoying all things, large and small, with a boyish zest. He showed and explained the calculating machine (French, not Babbage's), which saves him much in time and brain, as it can multiply or divide ten figures accurately. We came upon an admirable portrait of him at S. John's College, before he accepted a Pembroke Fellowship and migrated thither." The first mention of the name of Adams as the discoverer of Neptune was by Sir John Herschel, in the _Athenæum_, on October 3rd, 1845. And a letter from Professor Challis to that journal on 17th October described in detail the transactions between Adams, Airy, and himself. Naturally enough the French were highly incensed at the notion that an obscure Englishman had forestalled Leverrier in the discovery, and Airy himself was annoyed at his own negligence in not looking into the memoir by Adams, and took up the matter with some personal feeling. It was certainly startling to realize that the Astronomer Royal had had in his possession data that would have enabled the planet to be discovered nearly a year before Leverrier had, by a different course of argument and calculation, arrived at the conclusion that there existed a planet which was the disturbing element in the orbit of Uranus. As to Adams himself, he had not a particle of conceit and pride in him; he did not care to have his name proclaimed as the discoverer. Forty years later, he said simply and characteristically that all he had wished for was that English astronomers to whom he had communicated the result of his calculations, pointing out the precise spot in the sky where a planet was to be found, would have taken the trouble to turn their telescopes upon that point and discover the planet, so that England might have had the full credit of the discovery. [Illustration: EX·LIBRIS JOHANNIS COUCH ADAMS] His long-suppressed investigation was not laid before the Royal Astronomical Society till November 13th, 1846. The publication, of course, stirred up much controversy, and the scientific world was divided into Adamite and anti-Adamite factions. Adams refused knighthood in 1847, and declined the office of Astronomer Royal on Airy's retirement in 1881.
