AG’s review of Alphonse de Candolle’s paper [Am. J. Sci. 2d ser. 35 (1863): 430–44] is excellent.

Does not AG consider that orchids oppose Oswald Heer’s view that species arise suddenly by monstrosities?

Infers that AG cannot explain the angles of phyllotaxy; has been looking at Carl Nägeli on the subject.

Reports Gaston de Saporta’s belief that natural selection will ultimately triumph in France.

Is working slowly at Variation.

Reports his observations on the imperfect flowers of Viola and Oxalis.

Thanks AG for references about phyllotaxy

and information on marriage laws.

Has been looking for dimorphism in Phlox and Euonymus.

Has observed the irritability of tendrils of Echinocystis with great interest. Was also struck by the rotating movements of the leading shoots, which he proposes to investigate.

Anticipated AG’s attitude on design in orchids. Does he not think that the variations that gave rise to fancy pigeon varieties were accidental?

Has been working hard at Lythrum

and spontaneous movements of tendrils.

Defends Drosera as a "sagacious animal" but does not know whether he will ever publish on it.

Comments on political situation in U. S.

Has not worked for six months due to illness.

Has been looking at climbing plants.

Hermann Crüger’s paper shows that CD was right about Catasetum pollination. Crüger’s account of pollination of Coryanthes "beats everything".

Describes the flower and mode of action of a particular orchid.

Has been examining Spiranthes and is experimenting to see whether insects are necessary for its fertilisation.

It seems that Oncidium is designed so as not to be fertilised.

Is slowly writing Lythrum paper [Collected papers 2: 106–31].

Thanks for [Charles?] Wright’s observations on orchids

– could he note what attracts insects to Begonia and Melastoma? H. Crüger, who was going to observe Melastomataceae, has died.

Describes the climbing habits of Bignonia capreolata and Eccremocarpus scaber.

How does AG know the perfect flowers of Voandzeia are quite sterile?

He has a case of dimorphism in holly; asks AG to report on American hollies.

Has finished Climbing plants;

resuming work on Variation.

Sends abstract of John Scott’s paper [see 4332].

Has received review of Herbert Spencer but cannot believe AG wrote it unless he has muddled his brains with metaphysics.

Sends question [missing] for an ornithologist.

Is plodding on at Variation.

Has added to Climbing plants.

JDH writes that he has no fruit of Fothergilla & asks Asa Gray whether it's Endocarp separates as coccis. Mentions Parry's seeds. Has been busy with GENERA PLANTARUM, describes the work he has been doing on various orders, genera and tribes for the book incl.: calyciflorous orders, Cucurbitaceae with input from Charles Victor Naudin, Melastomaceae, Abobreae, Elatereae, Loaseae, Passifloreae, Papayaceae, Modecca, Acharia, Begonias, Cartesia[?], Hamamelideae, Saxifrageae, Bruniaceae, Grubbia, Santalaceae & Corneae. [Letter incomplete, it bears no valediction or signature but is written in the hand of Sir Joseph Dalton Hooker].

Congratulates AG on the "grand news of Richmond".

Still interested in dimorphism and would welcome new cases.

Working on Variation

and correcting proofs of Climbing plants.

Would like seed of AG’s dimorphic Plantago.

Cannot understand how the wind could fertilise reciprocally dimorphic flowers.

No summary available.

Gratified by AG’s praise of "Climbing plants".

Thanks for Specularia seed.

JDH tells Asa Gray about the death of his father William Jackson Hooker, at age 80. A few days before his death WJH had given Queen Emma of the Sandwich Islands [Hawaii] a tour of RBG Kew, walked in the gardens with [Thomas] Thomson & [Miles Joseph] Berkeley & went with JDH to see the subtropical plants in Battersea Park. JDH's mother [Lady Maria Hooker] returned from Yarmouth to be by her husband's side. There is an epidemic of throat infections in Kew. JDH himself got sick with Rheumatic fever, possibly as a result of keeping vigil over his father. He went to stay with [Archibald] Campbell in Notting Hill to recuperate. He mentions some of the treatments he had & some lingering symptoms. [William Francis] Cowper [Temple] wrote offering JDH the Directorship of RBG Kew & proposing some changes to the Gardens. JDH wants proper scientific help & another assistant such as [Daniel] Oliver to help handle correspondence & work on Ferns. Discusses what assets his father leaves & the inheritance that his children will get, incl. herbarium & library which are left to JDH with instruction to offer them to the nation at a reasonable rate. JDH has heard that [Charles Robert] Darwin's health is improving under Dr [Henry] Bence Jones. JDH gives a report on the whereabouts of his children: William Henslow Hooker, Charles Paget Hooker, Harriet Anne Hooker, Brian Harvey Hodgson Hooker. Adds that his Mother and his sister Mrs [Elizabeth] Lombe are in Yarmouth & Norfolk respectively & will winter at Torquay. The only mourners at WJH's funeral were JDH's sister Maria [McGilvray], his brother in law Thomas Robert Evans Lombe, his uncle Thomas Brightwen & some old RBG Kew foremen including the old & new John Smiths.

AG’s article on climbing plants [Am. J. Sci. 2d ser. 40 (1865): 273–82] is admirable and complimentary.

Reports Fritz Müller’s observations on climbers.

Experiments on dimorphism with Mitchella and Pulmonaria.

AG’s second article on Climbing plants [Am. J. Sci. 2d ser. 41 (1866): 125–30].

Fritz Müller’s observations on Rubiaceae.

New edition [4th] of Origin.

Thanks for AG’s trouble about new edition of Origin.

Will be printing his new book [Variation] at the end of the year.

[Forwarded by AG, with covering note, to Mr Fields of Ticknor & Fields.]

L. Agassiz’s evidence [for glaciation of America] is very weak.

Thanks AG for arranging for American edition of Variation, but doubts that the book will be successful.

Has found no differences in pollen of Rhamnus so cannot conjecture whether it is dimorphic.

The common oxlip of England is certainly a hybrid between the primrose and the cowslip whereas Primula elatior is a good species.

Reports experiments on the relative vigour of seedlings from cross- and self-fertilised plants.

JDH writes that he looks forward to Asa Gray's new edition of the MANUAL [OF THE BOTANY OF THE NORTHERN UNITED STATES]. JDH has found revisions to the New Zealand Manual difficult, especially regarding Cryptogams; amongst which only the algae have been well classified thanks to Harvey. Discusses the delay in publishing the manuscript of GENERA OF CAPE PLANTS. Praises Lefever. Complains that Muller is giving his name to pre-existing species & creating synonyms, apparently on the advice of Alphonse De Candolle [ADC] whom JDH finds arrogant & narrow minded. ADC has been unwilling to accept any of JDH's proposed changes to PRODROMUS SYSTEMATIS NATURALIS REGNI VEGETABILIS. Munro's paper on Bambuseae & Triana's paper on Melastoma will be read at the Linnean Society. Morse & Sons of Boston called at Kew. JDH reads THE NATION. Is glad that the Tories will take up 'the Alabama Case', though JDH is 'a Whig myself' (if anything), he thinks the aristocracy had wiser ideas during the 'American War'. He comments on the relative morals, honour & violent tendencies of the upper, middle & lower classes in Britain, with reference to natural selection. Gives his opinion of Malthus' book on population [AN ESSAY ON THE PRINCIPLE OF POPULATION].

JDH informs Asa Gray that he will be happy to see Mr Dexter or Lawrence regarding the Peabody affair. He has found an earlier indication of Euploca in PEOCEEDINGS OF THE AMERICAN ACADEMY. Has asked Munroe to reply to Gray directly. Munroe recently read a paper on Bambuseae at the Linnean Society. JDH adds that he is sending Gray a photograph.
