To J. D. Hooker   31 December [1858]

Summary

Replies at length to JDH’s worried reaction to his comments on lowness of Australian plants. CD distinguishes between "competitive highness", i.e., which fauna would be exterminated and which survive if two faunas were placed in competition, and ordinary "highness" of classification.

From Charles Lyell   30 November 1860

Summary

Satisfied that CD finds his conjectured rate of elevation and long periods of stasis reasonable, even if these periods cannot be estimated. Explaining upheaval by subterranean lava flow makes these pauses plausible. Suspects that mountainous areas move more than lowland and coastal areas. General upheavals or subsidence in Europe in glacial period are unlikely. Believes with Jamieson that there was glacial action in Scotland before its submergence and that it was equally mountainous then. Subterranean upheaval visits different countries by turn. Horizontal Silurian strata must have been submerged and upheaved. Rest has always been the general surface character. Believes, however, that the quantity of late Tertiary movement is against CD’s belief in the constancy of continents and oceans: perhaps since the Miocene period, but not since the Cretaceous.

From C. F. Martins   3 February 1872

Summary

CD’s views, on which he has lectured, will succeed with time.

Joachim Barrande’s refutation cannot be impartial because he is a devout Catholic.

Many young French naturalists support CD but are silent for fear of their jobs. Houget has been reprimanded for his Darwinism.

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".

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?
