Summary

Cases of "dioecio-dimorphism" as in primroses are widespread. AG always considered them the first step toward bisexuality.

Summary

The pamphlet of AG’s Origin reviews [Natural selection not inconsistent with natural theology (1861)]. CD will bear half the costs of publishing.

Will write to Huxley about Chauncey Wright’s review of Origin.

Summary

Forwards A. Gray’s letter [inquiring whether THH would be interested in printing Chauncey Wright’s review of Origin].

Summary

Agassiz is strongly opposed to Origin, but CD thinks K. E. von Baer may come out in support.

Discusses the possibility of favourable monstrosities in the light of Theophilus Parsons’ essay ["On the origin of species", Am. J. Sci. 2d ser. 30 (1860): 1–13].

Summary

Encloses note from Huxley [see 3022], who would be grateful for Chauncey Wright’s review.

Summary

On JDH’s suggestions for new edition of Origin.

Gray’s Atlantic Monthly articles to be published [in England] as a pamphlet.

Summary

Asks AG to send his reviews [of Origin] as soon as he has definitely fixed on a title for the pamphlet.

Summary

Feels his poor stomach "saved" him from overworking his head.

Summary

Comments on AG’s memoir on Japanese plants [see 2599]; relationship of Japanese flora to N. American.

Summary

Encloses letters from H. G. Bronn, Asa Gray, and C. J. F. Bunbury, concerning the Origin.

Will send review by Gray and a notice by Bronn.

Says Bronn will superintend the German translation.

Comments on lecture by Huxley [at Royal Institution, 10 Feb 1860, Not. Proc. R. Inst. G. B. 3 (1858–62): 195–200]. Has remonstrated with him for saying sterility is "a universal and infallible criterion of species".

Summary

Origin has "stirred up the mud with a vengeance"; AG and three or four others have saved CD from annihilation and are responsible for the attention now given to the subject. Reports events at Oxford BAAS meeting.

New evidence supports AG’s view of a warm post-glacial period.

Discusses his recent orchid observations.

Poses AG a question on design in nature.

Summary

Glad to hear of MTM’s papers [? "On a peloria and semidouble flower of Ophrys aranifera, Huds.", J. Linn. Soc. Lond. (Bot.) 8 (1865): 207–11 and "Observations on the morphology and anatomy of the genus Restio, Linn.", J. Linn. Soc. Lond. (Bot.) 8 (1865): 211–55].

CD doubts the value, for origin of species, of parallels between peloria in "distinct groups".

Gärtner proved the stigma can select its own pollen from a mixture of foreign pollens. But much evidence shows varieties of same species are prepotent over a plant’s own pollen.

MTM’s father [William] believes that variation goes on for a long time once it has commenced.

Summary

American edition of Origin. AG’s assessment of the book’s weak and strong points. Suggests Jeffries Wyman would be a useful source of facts and hints for CD.

Summary

Lyell, de facto, first to stress importance of geological changes for geographical distribution.

Asa Gray has given CD too much credit for theories of geographical distribution.

Reaction to hostile criticism

and debt to Lyell, Huxley, JDH, and W. B. Carpenter.

Summary

JW’s case of black hogs shows marvellous relation of colour and constitution.

Could JW get information about eyes of cave rat?

Was JW struck by length of hind legs of male cattle?

CD has long shared JW’s doubts that mutilations were ever inherited but Brown-Séquard’s case seems to settle question.

Is not case of cats with blue eyes being deaf very odd?

Spinal stripes on horse too common to explain in way informant supposes.

Believes Owen "goes a long way with us", though he attacked CD in Edinburgh Review.

"No one other person understands me so thoroughly as Asa Gray."

Summary

Has received second part of AG’s Atlantic Monthly article ["Darwin on the origin of species", 6 (1860): 109–16, 229–39], and would like to have it reprinted in England with the first part.

Regrets no reviewer has touched upon embryology, which he feels provides one of his strongest arguments.
