It seems that this French publication at last aroused Sir George Airy, who now admitted that the calculations of Adams might be correct in form and deduction.  He accordingly sent word to Professor Challis to begin a search for the unknown orb.  The latter did begin the work of exploration, and presently saw the planet.  But he failed to recognize it!  There it was; but the observer passed it over as a fixed star.  As for Leverrier, he sent his calculations to Dr. Galle, of Berlin; and that great observer began his search.  On the night of the twenty-third of September, 1846, he not only saw but caught the far-off world.  There it was, disc and all; and a few additional observations confirmed the discovery.

Hereupon Sir George Airy broke out with a claim that the discovery belonged to Adams.  He was able to show that Adams had anticipated Leverrier by a few months in his calculations; but the French scholars were able to carry the day by showing that Adams’ work had been void of results.  The world went with the French claim.  Adams was left to enjoy the fame of merit among the learned classes, but the great public fixed upon Leverrier as the genius who did the work, and Dr. Galle as his eye.

Several remarkable things followed in the train.  It was soon discovered that both Leverrier and Adams had been favored by chance in indicating the field of space where Uranus was found.  They had both proceeded upon the principle expressed in Bode’s Law.  This law indicated the place of Neptune as 38.8 times the distance of the earth from the sun.  A verification of the result showed that the new-found planet was actually only thirty times as far as the earth from the sun.  In the case of all the other planets, their distances had been remarkably co-incident with the results reached by Bode’s Law; but Uranus seemed to break that law, or at least to bend it to the point of breaking—­a result which has never to this day been explained.

It chanced, however, that at the time when the predictions of Leverrier and Adams were sent, the one sent to Galle and the other to Challis, Uranus and the earth and the sun were in such relations that the departure of the orbit of Uranus from the place indicated by Bode’s Law did not seriously displace the planet from the position which it should theoretically occupy.  Thus, after a little searching, Challis found the new world, and knew it not; Galle found it and knew it, and tethered it to the planetary system, making it fast in the recorded knowledge of mankind.

While Daniel O’Connell, the greatest Irishman of the present century, despairing of the cause of his country, lay dying in Genoa, and while Zachary Taylor, at the head of a handful of American soldiers was cooping up the Mexican army in the old town of Monterey, a new world, 37,000 miles in diameter and seventeen times as great in mass as the little world on which we dwell, was found slowly and sublimely making its way around the well nigh inconceivable periphery of the solar system!
