In this first of three volumes, Charles Lyell (1797-1875) sets forth his powerful uniformitarian argument: processes now visibly acting in the natural world are essentially the same as those that have acted throughout the history of the earth, and are sufficient to account for all geological phenomena.

He defines four periods of the Tertiary Newer Pliocene, Older Pliocene, Miocene, and Eocene and argues that the deposits dating from each period demonstrate the uniformity of processes...
