Summary

Henslow has sent him CD’s Galapagos plants along with Macrae’s. JDH impressed by the island endemism, which "overturns all our preconceived notions" on centres of radiation. Describes the extent, and the sharp demarcation at longitude 60° W, of the American and European Northern Hemisphere floras. CD’s plants among those he is using to do Antarctic flora. Drimys winteri shows a graded series of states down the length of the South American continent.

Summary

Asks WJH to thank his son [J. D. Hooker, away on Antarctic survey] for his note. Has also read a letter JDH wrote to Lyell. Hopes JDH will publish a journal. If he publishes an Antarctic flora, CD will place his collection of South American alpine plants at his disposal.

Summary

CD gratified that ED wants to translate his Journal. Will send a copy of Coral reefs, which contains a fuller treatment of topic. Perhaps ED would insert a note to this effect. Can lend woodcuts from Coral reefs if ED wants. CD will send a few corrections; he wants to amend way he criticised Agassiz’s glacier theory.

He is also enclosing a questionnaire concerning differences between races or varieties and species, about which he intends to publish sometime.
