From Charles Lyell   17 June 1856

Summary

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".

Will CD explain why the land and marine shells of Porto Santo and Madeira differ while the plants so nearly agree?
