Has "given the slip" to Nepenthes, but is setting a plant up in an enclosure for special observation.

Has some splendid Sarracenia and will perform any miracle regarding them CD puts him up to.

Charmed with CD’s account of Pinguicula. Would like to try whether Lychnis has the same use of viscid fluid.

Has written for English Utricularia for CD.

Thinks Frank and he have worked out Pinguicula well and they long to attack Utricularia. Tried several plants with sticky glandular hairs; some few absorb ammonia, but the greater number do not. If JDH sends plant or seed of Lychnis CD will examine it to see whether it catches many flies. Asa Gray has written him much about Sarracenia, with a specimen showing the splendid dodge by which ground insects are enticed up and then drowned. Describes how it may be investigated, to see whether it absorbs decayed matter from flies, or ammonia thus generated.

Sends results of his observations on Nepenthes. Would be grateful for any hints for further observations.

It would be interesting to prove that some plants feed on decayed animal matter whilst others like Drosera can digest fresh animal matter. Suggests the method for observing this.

No summary available.

The appetite of Nepenthes for hard-boiled egg is prodigious.

Suggests experiments to try [with Nepenthes]. Asks JDH to test whether cabbage seeds and peas exposed to the ferment germinate.

Asks what can be the meaning of appendages to tips of leaflets of enclosed Acacia or Mimosa.

Is at fibrin today.

Michael Foster suggests coagulation of protoplasm may be diseased, not digestive, symptom.

F. M. Balfour is at Kew today.

The Acacia must be Belt’s "Bulls’ horns".

The complexity of Utricularia has driven Frank and CD almost mad. Suspects it is necrophagous, i.e., it cannot digest, but absorbs decaying animal matter.

Foster is certainly in error. Every insect that Drosera catches causes aggregation.

Two Nepenthes have devoured two pieces of fibrin [sketch shows size] in three days.

Has CD any objection to JDH’s giving an account of CD’s Drosera observations at Belfast [BAAS meeting] in a résumé of pitcher-plant results ["Address to the department of botany and zoology", Rep. BAAS 44 (1874): 102–16]?

"It is grand about Nepenthes."

JDH is welcome to notice in any way any of CD’s published or unpublished results with insectivorous plants. Gives an abstract of his observations on Drosera.

JDH explains he has not written to Asa Gray recently because he is particularly busy during the absence of his aide, William Turner Thiselton-Dyer, who is at South Kensington. JDH is working on a botanical primer for the Macmillan series & doing experiments for himself & Charles Darwin on insectivorous or carnivorous plants: Cephalotes, Nepenthes & Sarracenia. Has neglected work on GENERA PLANTARUM. Has had difficulty getting good systematic contributions for the FLORA INDICA, Thiselton-Dyer & Hiern did good work but Edgeworth, Masters, Andrews & Lawson all needed a lot of correction. Tells Gray about his trip to Florence, Italy for a Congress, run badly by Filippo Parlatore who JDH calls a Tragopogon [also known as 'goatsbeard'] & a 'little toad'. During the trip he saw the Miss Horners, Bakle & his wife, & Mrs Harvey. He also went to Paris, Nimes, Montpelier, Antibes, Hanbury's brother's place near Montara, Genoa, Spezzie [La Spezia] & Pisa & returned via Venice, the Brenner [Pass] Munich & Paris. [Letter appears incomplete. It bears no signature but is written in the hand of Joseph Dalton Hooker.]

Stupefied by CD’s trouble and kindness. All he wanted for Belfast meeting was assurance that mention of published work on Drosera, etc., in Nature, etc., would not interfere with CD’s book.

Would like his Nepenthes results to go to CD or to Royal Society, but prefers CD take them.

Cephalotus very puzzling.

Peas and cabbage grow twice as fast after two days’ immersion in Nepenthes as when placed in distilled water, but four days’ immersion seems to kill them.

Has a splendid Australian Drosera twice as big as D. rotundifolia.

JDH should do as he likes with insectivorous plant materials.

He has always thought telling JDH what he has been doing was as good as publishing.

Cephalotus seems as horrid a puzzle as Utricularia.

Nepenthes will turn out a great job if the pitchers of different species act differently. JDH’s paper on Nepenthes [Rep. BAAS 44 (1874): 102–16] is too long for CD’s book. Well deserves a place in Philosophical Transactions.

JDH informs Sir William Turner Thiselton-Dyer that Lord Hatherley has found in George Bentham's favour on all points [regarding the amendment of the Linnean Society by-laws]. JDH still hopes [Marcus Manuel] Hartog will accept the post [of Assistant Director, Peradeniya Botanic Garden] in Ceylon [Sri Lanka]. In a post script JDH briefly discusses a recent experiment with carnivorous plants: Nepenthes rafllesiana & phyllamphora & mentions the difficulty of studying Darlingtonia & Cephalotus.
