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?
