On painful state of CD’s reception in France.

Credits himself with stimulating most of the American work on plant cross-fertilisation. Sends his review of Cross and self-fertilisation [in Penn Monthly (June 1877)]. Suggests CD, A. Gray, and TM now agree on the extent of self-fertilisation in nature.

"Young Mr Appleton", when in London, told Murray’s to send a set of stereotype plates [of Forms of flowers]. A printing of 1000 copies has been ordered for the English edition.

Sends CD lithograph plates as examples of a book he hopes to publish.

Reports monstrous Papaver hybridum not mentioned in M. T. Masters’ Teratology [1869].

Thanks him for his book [Du Darwinisme ou l’homme singe (1877)] and letter.

Thanks for review. Fears "we must agree to differ".

Continues experiments on the colour of goldfish as affected by light and presence of plants.

Thanks AD-P for plates [from Arnold and Carolina Dodel-Port, Atlas der Botanik (1878–83)]. Will be useful to all who teach botany.

Asks for CD’s "Sketch of an infant" [Collected papers 2: 191–200]. He has made observations on new-born children and mammals to determine what behaviour is inherited and what acquired.

Has enjoyed CD’s last publications, especially on self-fertilisation of plants.

Believes a visit by CD to the U. S. would do much to promote his theories.

JDH writes to his wife Lady Hyacinth Hooker about his unpleasant voyage on board the 'Parthia' [to Boston, USA]. It is a screw ship rather than a paddle wheel steamer & the strange motion makes many of the passengers sea sick. Other passengers include: an Irish relation of Mrs [Jane Loring] Gray; a relative of Motley's daughter who married Sir William Harcourt MP the brother of Harcourt of Nuneham; the Strachey's [Sir Richard & Lady Jane Maria]. JDH has spent a lot of time reading in his cabin, he has read: [Baron Thomas Babington] Macaulay, [John] Evelyn's diary, Keye's lives of Eminent Indians, some of [Henry Wadsworth] Longfellow's Poems & one volume of [Charles] Lyell's 1st journey in America. Describes the ship's captain as 'a bright intelligent Scotsman' who engaged in debate about the effects of emotion & principles. The ship doctor is an Irish Army surgeon who served in India & is a good storyteller. The long journey & poor travelling conditions have put JDH off another trip across the Atlantic to America unless Hyacinth persuades him. The letter continues after JDH's arrival at Boston Harbour. Motley & [Charles Sprague] Sargent will come to meet JDH & party on a Government steamer & escort them through customs. In a post script JDH adds that he has been made welcome in Cambridge, Massachusetts & will start soon for Colorado. Requests that [John] Smith & [Sir William Turner] Thiselton-Dyer send a corrected copy of the fern list to Professor Sargent.

Asks permission to print translation of "A biographical sketch of an infant" [Collected papers 2: 191–200] in Kosmos.

Notes divisions among German Darwinists.

CD admires Herbert Spencer’s genius but not his "deductive style" of expression.
