Scott would be very welcome at Down for a short visit.

Asks JDH to name a Bignonia.
Coming to end of climbing plants paper.
R. I. Murchison has criticised ACR’s glacial lake theory in his Presidential Address to Royal Geographical Society [J. R. Geogr. Soc. 34 (1864): cix–cxcii].
ACR has finished his Geology of N. Wales.
Is sending CD an article which he hopes will make him see that there are more causes than ice to account for the structure and wearing away of rocks. [Possibly "On the relative powers of glaciers and floating ice-bergs in modifying the surface of the earth", Can. Nat. 2 (1865): 21–33.] [J. of R. Geog. Soc. London 34 (1864)]
First draft of climbing plants paper is completed.
Nepenthes is a true climber.
Scott has visited Down.
Believes he gave JDH wrong address.
Hookers and Lyells will visit Lubbocks so he cannot see CD in London.
Will CD sit for Woolner?
CD is not well enough to sit for Woolner.
Two Bignonia plants, which JDH does not distinguish as species, can be separated by differences in climbing and sensitivity behaviour.
Wants to write a non-quarrelsome reply to R. A. Kölliker ["Darwin’sche Schöpfungstheorie", Z. Wiss. Zool. 14 (1864): 174–86] in the Reader. Lyell opposes, but E. A. Darwin and Hensleigh Wedgwood support the idea.
John Scott has sailed.
Concurs with Lyell that CD need not reply to Kölliker.
CD’s Bignonia plants cannot be told apart without flowers.
Can understand EH’s feelings on death of his wife.
CD was impressed by manner in which species in South America are replaced by closely allied ones, by affinity of species inhabiting islands near S. America, and by relation of living Edentata and Rodentia to extinct species. When he read Malthus On population, the idea of natural selection flashed on him.
Agrees with EH’s remarks on Kölliker ["Darwin’sche Schöpfungstheorie", Z. Wiss. Zool. 14 (1864): 174–86].
Asks EH to thank Carl Gegenbaur [for Vergleichende Anatomie der Wirbelthiere (1864)].
