Has sent CD a paper partly relating to Dr Creighton’s curious observations ["Some points of science and practice concerning cancer", Br. Med. J. (1878) pt 1: 219–24].

Encloses letter from R. A. Blair concerning goose with abnormal wing. Hopes WHF will look at bones.

Asks CD’s opinion on number of copies to be printed of Cross and self-fertilisation [2d ed.]. Now that it is revised, they will stereotype.

Type of Forms of flowers stands, awaiting CD’s corrections, before stereotyping and printing of more copies.

RC regrets delay in supply of Origin.

Will bring photograph of goose with abnormal wing to London.

Comments on letter on potato experiments JT intends to publish. Will talk with T. H. Farrer concerning JT’s work. Could he undertake work if aided by moderate grant or subscription?

Sends CD a copy of his memoir on the fenland [Geology of the fenland (1877)].

Outlines the results of his recent researches into the geological history of man, the development of Palaeolithic culture, the occurrence of Palaeolithic remains in the boulder-clays of eastern England, and their relation to glacial and inter-glacial periods.

CD solicits JDH’s aid in obtaining Government funds for James Torbitt’s efforts to breed disease resistance in potatoes.

Fertilisation of wheat.

Would like to borrow Wilhelm Rimpau’s papers.

Thanks for letter. Prepared to continue experiments if aided. Thinks of distributing new [potato] varieties. Believes seeds should be planted this spring.

T. H. Farrer will consider which department of Government to apply to [for funds for potato experiments]. Government will probably ask Hooker for advice, so CD has written to him. How much money does JT need?

CD’s quest for Government support for potato experiments by James Torbitt.

CD again asks JDH to support Torbitt’s project to breed disease-resistant potatoes. He has also sought support of Farrer, Duke of Richmond, and James Caird.

T. H. Farrer has talked to James Caird. He believes Royal Agricultural Society will cultivate JT’s seeds. CD pledges £100 for JT’s own experiments.

THF would do a good deal if he gets Agricultural Society to rear cross-fertilised seeds. Society excellent channel for distribution of fungus-proof variety [of potato]. If James Torbitt will carry on work another year, CD will offer him £100.

Describes James Torbitt’s plan for producing disease-resistant potato varieties. [Letter is an earlier version of 11406.]

His attempts to obtain a Government grant for Torbitt seem hopeless.

CD is suffering from constant swimming of the head.

Supports Torbitt. Keenly aware of danger of growing crops from a single variety. Torbitt’s paper to Belfast BAAS meeting ["On the potato-disease", Rep. BAAS 44 (1874): 134] was sat upon.

Hopes to visit [Sara and William] later in the year.

Describes a post-mortem dissection of a chimpanzee’s brain. The several doctors who observed it were struck by its resemblance to the human brain.

Thanks for letter. Comments on SBJS’s research on Palaeolithic flint tools.
