Sends photograph.

THH wishes he could write the popular zoology but writing is a boring and slow process when he is not interested, and he is overburdened with lectures.

Thanks for [E. Eudes?] Deslongchamps’ paper.

Henry Huxley born.

Leader in Reader [4 (1864): 821] is by THH. It has got him into trouble with some of his friends.

Sends Catalogue [of the collection of fossils in the Museum of Practical Geology (1865)], most of which was written in pre-Darwinian epoch [i.e., 1857].

Hears magnum opus [Variation] completely developed, though not yet born.

Glad to read what CD sends. Any glimmer of light on those subjects is of utmost importance.

Quotes a letter from Haeckel on progress of Darwinism in Germany.

MS arrived. Has glanced at it and sees he must put on his sharpest spectacles and best considering cap.

Did not intend to persuade CD against publishing Pangenesis. Will not take the responsibility, nor risk being made a horrible example 50 years hence.

Has returned from holiday. Family news.

Concern over Hooker’s health.

Has taken memorial to G. H. Richards, the Hydrographer. He favours the proposal and will instruct Capt. Mayne. THH will communicate with Dr Cunningham, the naturalist for the expedition.

Thanks for 4th ed. of Origin.

What a basting CD gives "our mutual friend" [Owen].

Glad he argrees with THH on Jamaica affair [Gov. Eyre and the "rebellion"].

On Haeckel’s Generelle Morphologie; the logical argument for natural selection is still incomplete. THH jumps over the hole by an act of faith.

Congratulations on George’s attaining Second Wrangler.

Variation has just arrived. Wishes he had two heads or a body that needed no rest.

Prof. Kühne would like to visit CD.

BAAS Norwich meeting. Hooker [President] came out in great force. "Darwinismus" spread over the sections and crept into everything. CD will have rare happiness of seeing his ideas triumph during his life.

CD is welcome to come for breakfast on Sunday.

Sends letter [from Haeckel?] opened by mistake.

August Schleicher a great loss.

Nothing new in Lushington’s letter. Two paragraphs are offensive – that THH sought to stir up Scotch Presbyterian prejudices against Comte at Edinburgh and that he had not read Comte.

Last letter was written to be passed on for Lushington’s edification. "(Standing on the points of my toes and my tail very stiff)." Is tiring of controversy as a waste of time. Begins to understand CD’s sufferings over Origin.

H. M. S. Nassau, surveying Magellan Straits, has found fossils at Gallegos River. They have been sent to THH by R. O. Cunningham [naturalist of H. M. S. Nassau]. Skull of entirely new ungulate mammal.

Has already referred Haeckel’s request to J. S. Bowerbank.

Has lost track of collectors and naturalists "by grace of the dredge" because of other work and ""the great question of "Darwinismus" which is such a worry to us all"".

Family health.

Will do his best on the tooth [sent by CD] but does not put much weight on conclusions based on a single tooth of a horse.

Darwin attacked by three clergymen at BAAS meeting [Exeter, 1869].
