Uranus. I'm afraid that the course we're taking will turn out like every other development. We began humbly, admitting that we're of the damned-- But our eyebrows-- Just a faint flicker in them, or in one of them, every time we hear of the "triumphal discovery of Neptune'"--this "monumental achievement of theoretical astronomy," as the text-books call it. The whole trouble is that we've looked it up. The text-books omit this: That, instead of the orbit of Neptune agreeing with the calculations of Adams and Leverrier, it was so different--that Leverrier said that it was not the planet of his calculations. Later it was thought best to say no more upon that subject. The text-books omit this: That, in 1846, everyone who knew a sine from a cosine was out sining and cosining for a planet beyond Two of them guessed right. To some minds, even after Leverrier's own rejection of Neptune, the word "guessed" may be objectionable--but, according to Prof. Peirce, of Harvard, the calculations of Adams and Leverrier would have applied quite as well to positions many degrees from the position of Neptune.
