The fact however that Neptune does not correspond to Le Verrier's solution can not detract from the merit or value of his investigation. Since, by using all the observations within his reach, he found an orbit and mass capable of accounting for the observed motions of Uranus, he is entitled in the opinion of mathematicians to all the admiration he would have received had such a planet actually moved in that orbit. To some it has appeared a matter of surprise that the new planet was not sooner discovered. Le Verrier's second memoir, which assigned the probable place of the disturbing body, was presented to the Academy on the first of June, 1846; and his third memoir (containing every thing which Dr. Galle had in his possession at the time of his discovery) was presented August 31st; yet Galle's discovery was not made till September 23d.
