Summary

Concern over CD’s health. Advises him to get one of the cleverer young London doctors to communicate with Andrew Clark. Only way out of difficulties with Clark.

Summary

THH comments on G. A. Brullé’s paper ["Researches upon the transformations of the appendages of the Articulata", Ann. & Mag. Nat. Hist. 13 (1844): 484–6].

Summary

On classification and possibilities of a scientific morphology and zoology. CD’s "pedigree business" is important for physiology but has nothing to do with pure zoology any more than human pedigree has to do with the census. Zoological classification is a census of the animal world.

Summary

K. E. von Baer’s view of the air bladder of fishes.

Summary

Serial homologies in the Mollusca. Gives instances of repetition of homological parts in Radiata.

Summary

Has just finished Origin. CD has demonstrated a true cause for the production of species.

CD has loaded himself with unnecessary difficulty in adopting natura non facit saltum.

Summary

Announces great ally for CD: K. E. von Baer "worth all the Owens & Bishops that ever were pupped". Quotes Baer: "J’ai énoncé les mêmes idées que M. Darwin", but based only on zoological geography.

Summary

Would be glad to have Chauncey Wright’s [Origin] review for the Natural History Review.

Summary

Against all predictions his Edinburgh lecture was well received [Evidence as to man’s place in nature (1863)].

Took his old line about problem of infertility of hybrids as a test of CD’s views.

Report [from a newspaper] not quite right about what he said, but they have not refuted his statement that some form of progressive development theory is certainly true, nor that man and the apes come from same stock. Owen has gone in for progressive development in second edition of the Palaeontology [1861].

Summary

The Witness attacks THH’s lecture.

Assures CD he spoke more favourably of his doctrines than the reports show.

Agrees with CD’s arguments on sterility of hybrids and predicts physiological experiments will produce physiological species sterile inter se. Has come even closer to CD’s view especially since Primula paper. Will soon be more Darwinian than CD.

Summary

Glad to receive CD’s pat on back for address.

Wants to know what CD thinks of the argument on geological contemporaneity.

On his poor health.

Summary

The BAAS meeting at Cambridge was exhausting.

Owen came to attack him but was beaten; his paper fell flat.

A "society for propagation of common honesty in all parts of the world" was established at Cambridge [THH’s "Thorough Club"?].

Summary

Thanks for a contribution ["On the so-called ""auditory-sac"" of cirripedes", Nat. Hist. Rev. (1863): 115–16; Collected papers 2: 85–7]. Is sending a proof.

This year’s lecture to working men to be devoted to CD’s book.

Summary

Sends first three of his Lectures to working men [on our knowledge of the phenomena of organic nature (1863)]. Does not intend them to be widely circulated.

Summary

Has not answered CD’s former letters. Has been ill. Will look up fish business as soon as he is square again.

Summary

Pleads guilty to both criticisms of "Miss Henrietta Minor Rhadamanthus Darwin" [see 3896] of points in his Lectures [to working men].

Summary

Too busy to examine specimen. Will ask W. H. Flower to do it. Long catalogue of what keeps him busy and concerned.

C. Carter Blake, "a jackal of Owen’s", is the reviewer in Edinburgh Review and Anthropological Review [see 4223]. Has sent back his diploma of Hon. Fellowship to Anthropological Society.

Summary

Asks CD to sign certificate nominating Flower for Royal Society.

Summary

No doubt that Owen wrote "Oken" and the archetype book, which appeared in its second edition in French.

Pressures of work and family.

Summary

Surprised at Kölliker’s misunderstanding; of Flourens he could have believed anything.

Family news.
