CL still believes Eocene, Miocene, and Pliocene are satisfactory divisions of Tertiary epoch.

CD forgets an author [CD himself in Coral reefs] "who, by means of atolls, contrived to submerge archipelagoes (or continents?), the mountains of which must originally have differed from each other in height 8,000 (or 10,000?) feet". CL begins to think that all continents and oceans are chiefly post-Eocene, but he admits that it is questionable how far one is at liberty to call up continents "to convey a Helix from the United States to Europe in Miocene or Pliocene periods". Will CD explain why the land and marine shells of Porto Santo and Madeira differ while the plants so nearly agree?
