Thanks JDH for short sketch of botanical geography of Southern Hemisphere. Comments on his own S. American collections and observations; notes other Galapagos collections.
Queries on ratios of species to genera on southern islands. CD’s observations on distribution of Galapagos organisms, and on S. American fossils, and facts he has gathered since, lead him to conclusion that species are not immutable; "it is like confessing a murder".
Discusses books returned
and invites him to Down for a few days.
C. G. Ehrenberg would like some earth from Galapagos, Tierra del Fuego, and the Falklands; wishes to hunt for Infusoria.
Thanks for information for Ehrenberg.
Has just completed Volcanic islands.
Sends queries on Galapagos flora in particular and island floras in general; also on relationship of wide-ranging species to wide-ranging genera.
Affinity of Galapagos with nearest Pacific islands. Relationship between ranges of species in time and space. Comparison of Malden Island and Galapagos plants. Affinities of Oceania plants with continental floras.
Advice to JDH on problems of printing and publishing.
Remarks on differences of species between islets of Galapagos group.
Asks JDH to forward publishing information to J. E. Gray.
Has received JDH’s infusorial specimens for Ehrenberg.
Thanks for JDH’s interesting details about the Galapagos.
Clarification of CD’s query about the relationship between the range of a genus and the ranges of its constituent species.
Thanks for information on printing charges
and for clarifying "typical forms".
In a few days CD will go away for six weeks.
