But all the calcu-lations made on this supposition had to be constantlyrecommenced. They could never succeed in represent-ing all its positions, although the star moved veryslowly: the observations of one month would utterlyupset the calculations of the preceding month. Several months elapsed without a suspicion that averitable planet was under observation, and it was nottill after recognizing that all the imaginary orbits forthe supposed comet were contradicted by the observa-tions, and that it had probably a circular orbit muchfarther from the sun than Saturn, till then the fron-.

It was, in fact, more difficult than we may think toincrease without scruple the family of the sun. In-deed, for reasons of expediency this idea was op-posed. Ancient ideas are tyrannical. Men had solong been accustomed to consider old Saturn as theguardian of the frontiers, that it required a rare bold-ness of spirit to decide on extending these frontiersand marking them by a new world. William Herschel proposed the name of GeorgiumSidus the Star of George, just as Galileo had giventhe name of Medicean stars to the satellites of Ju-piter discovered by him, and as Horace had said JuliumSidus. Others proposed the name of Neptune, inorder to maintain the mythological character, and togive to the new body the trident of the English mari-time power; other
