But as Geographers use to place Seas upon that place of the Globe which they know not: so chronologers, who are near of kin to them, use to blot out ages past, which they know not. They drown those Countries which they know not: These with cruel pen kill the times they heard not of, and deny which they know not.

However, the small probability of a similar encounter [of the earth with a comet], can become very great in adding up over a huge sequence of centuries. It is easy to picture to oneself the effects of this impact upon the Earth. The axis and the motion of rotation changed; the seas abandoning their old position to throw themselves toward the new equator; a large part of men and animals drowned in this universal deluge, or destroyed by the violent tremor imparted to the terrestrial globe.
