Comments on review of Origin by Andrew Murray [Proc. R. Soc. Edinburgh 4 (1860): 274–91] and views of William Hopkins on Origin ["Physical theories and the phenomena of life" Fraser’s Mag. 61 (1860): 739–52; 62 (1860): 74–90]. The attacks will tell heavily.

Mentions Blyth’s failure to receive appointment as naturalist to China expedition of 1860.

Encloses letter from Asa Gray.

Discusses gestation period in domesticated dogs.

Comments on hybrid fertility.

Thanks for invitation [to stay with GR at Oxford], but his poor state of health requires him to stay in private lodgings.

Wants to hear from readers about the way in which the bee-orchid (Ophrys apifera) is fertilised. He has always found it to be self-fertilised but greatly doubts that the flowers of any plant are fertilised for generations by their own pollen. The bee-orchid has sticky glands, which would make it adapted for fertilisation by insects; this makes him want to hear what happens to its pollen-masses in places he has not observed.

CD’s response to criticism of natural selection. Exasperated at not being understood. He tries to narrow the gap between himself and JDH.

Discusses measurements of bees’ cells.

Discusses measurements of bees’ cells. Describes modification in structure of Melipona hive. Notes importance of natural selection.

Regrets to hear that he proposes to retire from the captaincy of the Hawkhurst Company of the Rifle Volunteers.

Mentions Etty’s illness.

A "coarsely contemptuous" review of Origin by Samuel Haughton ["On the form of the cells made by various wasps and by the honey bee; with an appendix on the origin of species", Proc. Nat. Hist. Soc. Dublin 3 (1860): 128–40].

Comments on reception of Malthus’ ideas.

Says William Hopkins does not understand him.

Discusses problem of term "natural selection".

J. A. Lowell’s review of Origin [Christian Examiner (1860): 449–64].

Relationship between instinct and structure.

Discusses blindness of cave animals.

The fallacy of Andrew Murray and others; the slight importance of climate.

CD’s plans are uncertain because of his daughter’s [Henrietta Darwin] fever.

If GR would kindly reserve rooms for CD near college, CD will write before the meeting [of British Association at Oxford] if he is prevented from coming.

Mostly taken up with JH advising AH about changing his course of studies at Cambridge, together with some family news from home.

Floral anatomy of Goodeniaceae: although flowers seem to fertilise themselves by pistil moving to anther, CD shows that insect agency is necessary. Wants JDH to check his interpretation of stigmatic surface.

Asks how Origin [2d ed.] is selling and whether a new edition is likely to be wanted "soon, ever, or never". Asks partly from curiosity, partly because of a break in his work, and the answer will decide what his next job will be.

Discusses recent reviews of Origin and has made a note on Owen’s [see 2737].

Has become interested in the floral structures of orchids.

Notes his recent observations on Primula; believes he has found male and female forms.

Glad to hear good news of Etty [Henrietta Darwin].

CD’s observations on Scaevola are capital. The indusium collects the pollen and is the homologue of the pollen-collecting hairs of Campanula. A boat-shaped organ forms a second indusium, the inside base of which forms the stigmatic surface. The latter later protrudes as horns, forming the stigma.

Describes W. H. Harvey’s scientific career and thinks his letter interesting. Agrees with Harvey that the primary agency of natural selection is as great a mystery as ever. [Response to 2823.]

Has long venerated her father [Carl F. von Gärtner]. Looks forward to reading his life. CD will do everything he can to make Gärtner’s name more generally known.

Would like confirmation of his London address before returning the books. Has borrowed from the Society the barometric observations made at Cracow.
