That the heavenly Bodies move round their own Axes, is, beyond all doubt, manifest to our Eye, in some of them, from the Spots visible on them. The Spots on the Sun (easily visible with an ordinary Glass) do manifest him to revolve round his own Axis in about 25¼ Days. The Spots on ♃ and ♂ prove those two Planets to revolve also from East to West, as Dr. Hook discover’d in 1664, and 1665. And ♀ also (although near the strong Rays of the Sun) hath, from some Spots, been discovered by Mr. Cassini, in 1666, and 1667, to have a manifest Rotation. V. Lowth. Abridg. Vol. 1. p. 382, and 423, 425. And such Uniformity hath the Creator observ’d in the Works of Nature, that what is observable in one, is generally to be found in all others of the same kind. So that since ’tis manifest the Sun, and three of his Planets whirl round, it is very reasonable to conclude all the rest do so too, yea, every Globe of the Universe.
