It is not carpal or tarsal bones that are increased [in six-fingered men] but generally only the digits and metacarpals.

Pectoral fins of fish and sharks.

Asks THH to check P. M. Roget’s statement that there is a rudiment of a sixth digit in frogs.

[P.S. missing from original.]

A note reminding THH to examine the rudiment of the 6th toe on the hind foot of a Batrachian.

Thanks for "monkey book" [Evidence as to man’s place in nature (1863)].

Must wait till he has finished Lyell [Antiquity of man (1863)].

Two criticisms (one by Henrietta Darwin) of THH’s Lectures [to working men].

Praise of Man’s place.

Owen’s muddling letter in Athenæum [21 Feb 1863, pp. 262–3].

Is disappointed in Lyell’s excessive caution on species and origin of man [in Antiquity of man].

Has caught a frog and examined its possibly rudimentary toe. Asks THH if he will dissect it.

Has heard THH is abused in Edinburgh Review and in Anthropological Review [reviews of Man’s place in nature, Edinburgh Rev. 117 (1863): 541–69 and Anthrop. Rev. 1 (1863): 107–17].

Owen on heterogeny and the aye-aye.

Has been very ill.

Will be obliged if Flower examines specimens. States questions he wants answered.

Thanks for Lectures on the elements of comparative anatomy [1864].

If Owen wrote article on "Oken" [Encyclopaedia Britannica, 8th ed.] and French work on archetype he never did a baser act [see ML 1: 246 n.].

Bad health lately.

Admires THH’s article on Kölliker’s and Flourens’ criticisms of Origin [in Natural History Review (1864): 566–80].

Appreciates THH’s note more than Medal.

Encourages THH to write a popular treatise on zoology.

Sends Mrs Huxley a quotation from Tennyson, with sarcastic comment.

Thanks for photograph, charmed by Mrs Huxley’s letter.

Regrets THH cannot do the popular work on zoology.

Has heard THH wrote leading article in last Reader ["Science and ""church policy"" ", 4 (1864): 821].

Thanks for Catalogue.

Has had a bad month. Somewhat improved as a result of John Chapman’s ice-bag cures.

Asks THH to read MS on his hypothesis Pangenesis. THH only man whose judgment on it would be final with him.

Thanks for THH’s willingness to read Pangenesis MS. Thinks some such view will have to be adopted but it overthrows, in an uncomfortable manner, ordinary development.

Thanks THH for reading Pangenesis MS. Will read Buffon and Bonnet (as he does not want to republish their views) and will try to persuade himself not to publish.

Has read Buffon; whole pages are like his own. But CD is not converted to non-belief. There is a fundamental distinction between Pangenesis and Buffon. Fears he may not resist publishing it, but will be cautious.

Has done nothing since 1 May. Slowly getting better under Bence Jones’s diet.

The Reader has been sold – would regret its failure as a newspaper for general science.

Pangenesis is recovering from shock it received from THH’s criticism.

Sends a draft of memorial to Admiralty [to be signed by geologists and palaeontologists] requesting that an expedition to survey Strait of Magellan collect fossils discovered by Admiral B. J. Sulivan [see 5142].

First impressions of Haeckel’s Generelle morphologie.

Has received THH’s [Lessons in elementary] Physiology [1866]

and reread Man’s place.

Asks THH to read revised "Hybridism" chapter in new edition of Origin. Hopes it will change THH’s view.

Convinced of P. S. Pallas’ view of loss of sterility under domestication.

Gives up plan to have Haeckel’s Generelle morphologie translated.

His big book [Variation] has gone to printer. Thinks of adding a chapter on man.

Will order Duke of Argyll’s book [Reign of law (1867)].

"Nature never made species mutually sterile [by selection]; nor will man.–"

Asks THH to think about a better name for "Pangenesis"; suggests "Cytarrogenesis" or "Atomogenesis", but still prefers vaguer "Pangenesis".
