Summary

Is preparing new edition of Origin [6th] in which he will introduce new chapter to answer Mivart’s criticisms. Mivart is unfair: suppresses facts in CD’s later editions.

Sends article [by Chauncey Wright, see 7940] reviewing Genesis of species.

Mivart writes to CD full of respect, but reviles him in print.

Summary

Honoured by Abutilon name; describes observations on its fertilisation.

Henrietta’s marriage a great loss to him.

Latest Quarterly Review has article, "evidently by Mivart", that cuts CD into mincemeat.

Asks for name of species of mouse J. S. Henslow used to keep [see 598].

Summary

Returns pamphlets.

B. T. Lowne’s observation [Mon. Microsc. J. 4 (1870): 326–30] that boiling does not kill certain moulds is curious, but then how account for absence of all living things in Pasteur’s experiment?

Always delighted to see a word in favour of Pangenesis.

Thiselton-Dyer’s paper ["On spontaneous generation and evolution", Q. J. Microsc. Sci. 10 (1870): 333–54] is Spencerian.

The chemical conditions for first production of life are said to exist at present, but in some warm little pond today such matter would be absorbed or devoured, which would not have been the case before living creatures were formed.

Summary

Sends proofs of Huxley’s article on Mivart, to be published in Contemporary Review ["Mr Darwin’s critics", 18 (1871): 443–76].

Summary

Thanks for information about Henslow’s mouse.

Summary

Finished the last proofs of Descent a few days ago. "I shall be well abused."

St George Mivart’s Genesis [of species]: very good, unfortunately theological. Will tell heavily against natural selection but not against evolution, and this is "infinitely more important".

Summary

Delighted to hear from Lyell of JDH’s return from successful ascent of the Atlas Mts.

Fears JDH found no Madeira or Canary types, but CD is pleased at his moraine discovery.

Thinks Lyell’s health is serious.

Summary

CD is considering repeating experiments on melastomads in which different pollen sizes produced differing seedling sizes.

Responds to JDH’s query on differences in pollen within the same species.

Summary

Will be in London until 21st. Would rejoice if JDH could come to lunch during their stay.
