Busy correcting proofs. Thanks for JDH’s remarks; asks him to send any other corrections soon; goes to press with second part of Journal of researches in less than a week.

Urges collections of all kinds on any isolated islands.

No summary available.

The translation of Humboldt’s Kosmos [Cosmos (1846–58)] is delayed.

Gives instances of peculiar genera with several good species in very small islands. Scarcity of insects on islands.

JDH cannot prove that there is much hybridising, but does not see why there should not be. "Bother variation, development & all such subjects, it is reasoning in a circle I believe after all."

Raises some points for revision of CD’s Journal of researches.

Southern island floras. "The more I ponder upon Insular Floras the less inclined I am to admit the mutation of species to any very great amount."

A son [George Howard Darwin] was born on Wednesday.

Sends queries on Galapagos flora.

Discusses JDH’s comments on [Journal of researches].

CD feels that with his views on descent "really Nat. Hist. becomes a sublimely grand result-giving subject".

"How differently people view the same subject, for I look at insular Floras … as leading to an opposite view to yours."

Answers CD’s questions relating to the flora of the Galapagos. [See 889.]

Thanks for facts on solitary islands having several species of peculiar genera; "it knocks on the head some analogies of mine".

Has long been trying to discover in how many flowers crossing is probable, but finds it difficult to show "even a vague probability of this".

Will JDH proof-read Galapagos chapter of Journal of researches?

Gives information on his Galapagos collection; explains why it differs from others.

No summary available.

Sorry to hear about condition of JDH’s grandfather.

Sends proofs of Galapagos chapter of Journal of researches.

Grieves to hear labels are displaced on his plants.

May he annotate [F. Gérard’s] L’espèce [(1844), extracted from Dictionnaire universel d’histoire naturelle, ed. C. D. d’Orbigny (1839–49)]?

Anxious to hear of JDH’s prospects [at Edinburgh].

Has completed his Journal of researches.

JDH’s grandfather’s death.

Collecting testimonials for the Edinburgh chair.

Condolences on JDH’s grandfather’s death.

When his wife can move, they will go to Staffordshire.

Returns some books; would like to see copy of Kosmos [by Alexander von Humboldt]. Would be proud owner of JDH’s work [Flora Antarctica (1844–7)].

The most experienced botanists argue for the "validity of species in nature". Against taxonomic "splitters".

CD’s Cape Tres Montes plants.

Going to Shrewsbury on Monday.

Means to attempt the question of species: "though I shall get more kicks than half-pennies, I will, life serving, attempt my work".

Thanks for Journal of researches.

Puzzled over pea flower from Cape Tres Montes.

Thinks species a fair and most profitable subject for discussion, but has no formed opinion of his own.

Kosmos [by Alexander von Humboldt] has arrived safely.

CD acknowledges his presumption in speculating on variation without having worked out his due share of species, but "for nine years it has been anyhow the greatest amusement to me".

Sorry to hear JDH did not get Edinburgh chair. Invites him to Down.

Would like to see JDH’s testimonials.

Disappointed with Kosmos.

Has visited Dean of Manchester, who is very heterodox on species.

JDH informs his father, Sir William Jackson Hooker, about developments in his candidature for the Chair of Botany at Edinburgh University, usually held by one person unifying the posts of College Professor, Regius Professor, & Curator of the Botanic Garden. He reports that [John Hutton] Balfour had previously refused to take the post of Chair without the garden curatorship leaving only JDH & Leller[?] as candidates. JDH is Crown nominated & has the support of the University Provost but needs approval from the Town Council. The Natural History Chair also needs dual approval, the Provost plans to petition Sir James Graham [Home Secretary] to relinquish all Government, or 'Crown', control over 1 chair in return for total control of the other, plus his guaranteed support for JDH's candidature. JDH does not think this will be well received as the government has put a lot of money into the college & botanic garden. JDH adds that Balfour has since revoked his conditional refusal of the post of Chair of Botany without the garden curatorship, & the Town Council is inclined to appoint him if only to demonstrate their influence to government. They also want someone with lecturing, not just botanical, credentials. JDH is dismissive of their opposition, if he got the posts of Regius Professor & Garden Curator the faculty would have to accept him. Only the College Professorship is in the gift of the Town Council, it would be the post devalued & JDH would be happy to free of it & the Council's oversight in exchange for the reduced salary. He concludes that it has all become a matter of politics. One Councillor suggested that JDH take Balfour's current position at Glasgow claiming it was of equal value, JDH disabused him. JDH mentions some people he has seen, or expects to soon, in Edinburgh: Nicoll, the Gibson Craigs, Deucher[?], Muir, Henderson & Smith, the Sands & Lord Falnor[?]. He also has invitations to Kilmun, Riccarton, the Smiths at Coulston, E. Hendersons & the Gardens.

Thanks for Antarctic flora [Flora Antarctica (1844–7)].

Agrees geographical distribution will be "the key which will unlock the mystery of species".

Could JDH look over a rough sketch on species?
