On, still on, we swept, away from the great orb of day, the Sun, which slowly grew less and less glorious. As we travelled onwards, we compared our experiences of the worlds we had seen, and examined the relics of them we had collected. The conclusion we came to was that which I had anticipated: the solar system is one, yet it is unity in diversity. The elements of matter are the same—the metals, the rocks, the main forms are one, as springing from the same great nebula of primæval chaos. But the combinations differ.
