Sends CD his photo

and a copy of his address at Hartford ["Change by gradual modification not the universal law", Proc. Am. Assoc. Adv. Sci. (1874) pt 2: 7–12]. Does not believe his observations are unfavourable to natural selection but feels there are other factors involved in the origin of form.

Discusses further his work on colour and sex in plants; the linking of high colour and maleness.

Will send a different Utricularia species when the seedlings are better established.

Thanks for sending papers by Hermann Hoffmann.

JDH thanks Asa Gray for his letter of 27 Aug. Mentions spiral vessels. Comments on English knowledge of foreign developments, comparing his systematic botany to the German way. Will be glad of a copy of Valron's[?] Index. Has received the Thistles & Torrey's sheets by Dix. Praises Belfast meeting, particularly lectures by [Thomas Henry] Huxley & [John] Lubbock. Apologises that Farlow's paper was not acknowledged. JDH is sending Gray a copy of his Belfast address, it will be published in THE PROCEEDINGS. Notices of Edwards' observations have been omitted in CURTIS'S BOTANICAL MAGAZINE, JDH implies because of a quarrel. JDH has stayed out of the Linnean Society row but is embroiled in conflict with [William] Carruthers who has complained to the Admiralty, in the name of the British Museum Trustees & through the Librarian Mr Winter Jones, that JDH has not been sharing botanical collections. Including unfounded appeals about the Welwitch collection, collections made by [William] Purdie & [Charles] Wilford, & JDH's own Antarctica collections; which were shared with Captain [James Clark] Ross. It is part of the campaign by Carruthers & [Richard] Owen to undermine JDH's position as a British Museum Trustee. Haveley[?] has also been drawn into the dispute. The illiberal museum policy is the real reason none of the Public Offices send specimens there. 'Old Gray' [John Edward Gray] will retire & be replaced by Gunther but Owen will not go until he has moved the [natural history] collection to the new building [Natural History Museum]. The natural history trusteeship, comprised of JDH, Duke of Devonshire, Duke of Argyll, Viscount Eversley, Sir P. Egerton, Sir G. Burrows is ignored. Thanks Gray for Fremontia seed, shared with [Gustave Adolphe] Thuret & [Thomas] Hanbury. He will continue to send seed to Bolander through the Smithsonian. Advises that Baker will send Refugia[?] & JDH will pay Leeman. Asks what lower Cryptogams of Wilkes' voyage have been published.

JDH writes to Sir William Turner Thiselton--Dyer [WTTD] about a recent stay with General Birch at Stranraer in the company of the Whites[?] & the Hamiltons. He also visited Lord Stair's Pinetum, run by a Mr Fowler, he particularly admired the white Douglas fir & some Pinus nobilis grown from grafts. He observed that Scotch Fir & Spruce won't grow there. He complains about the late train home from Galloway & the loss of their luggage en route to Wilesden via Carlisle. [John] Smith has gone to Cornwall. [Algernon Freeman-] Mitford is coming to stay with JDH at Kew, JDH likes Mitford so far. Russell, the RBG Kew 'orchid man', wants to leave in order to work on orchid greowing on a larger scale. JDH asks WTTD to consult Moore about a replacement at salary of 25 to 28 shillings plus room. JDH complains about the time he has to take correcting Lawson's reviews. JDH has received a proof corrected by WTTD with a passage about pitchers of Nepenthes marked as illegible, JDH does not know where it came from but has corrected it & sent it to the Academy. JDH complains about misprints in some 'copies' sent to Belfast for printing. JDH expects WTTD to see Harvey's Ericeae for Flora of South Africa whilst in Dublin. He apologises that he cannot send back Barkley's[?] bottles as promised. Reports that [Daniel] Oliver has returned from France & [John Gilber] Baker is away. JDH is preparing for some disageeable work with the Trustees of the British Museum regarding the Admiralty [probably in connection with a dispute over the collections from the HMS 'Challenger' expedition]. JDH intends to lay the case before Sir Philip Egerton privately. JDH asks WTTD to return an enclosed letter from Charles Darwin [enclosure not present].
