Summary

Reports on his examination of the dried specimens of Pinguicula at Kew to answer CD’s query whether all species secrete.

Summary

Thanks JDH for extract on Hedychium pollination; it shows CD’s prior interpretation was incorrect.

Summary

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

Summary

Farrer has taken the case to Northcote. JDH’s letter will show how overworked he is.

Summary

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.

Summary

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.

Summary

The row at the Linnean Society and other troubles.

The Agricultural Society has sent Anton De Bary £100 to investigate the potato disease – an insult to M. J. Berkeley, who had worked on it for 30 years.

Summary

Discusses effects of water on movement of insectivorous plants.

Has just found that Pinguicula can digest albumen.

Asa Gray writes that Sarracenia secretes trail of fluid to attract insects [see 9455].

Summary

Thanks for information about Hedychium. Hopes wings of Sphinx will be found covered with pollen for that will be a fine bit of prophecy from the structure of a flower to special and new means of fertilisation.

Has been at Descent so hard he has done nothing, not even H. Spencer’s answer.

Has not yet read Croll ["Ocean currents", London Edinburgh & Dublin Philos. Mag. 47 (1874): 94–122, 168–90].

Has heard nothing about Carter and Eozoon. Eozoon, he infers, is done for.

Has read Belt [The naturalist in Nicaragua (1874)]: best of all natural history travel books.

Has written to Fritz Müller about leaf-carrying ants.

Hopes to resume work on Drosera.

Summary

Probably a discussiion of J. D. Hooker’s feelings after death of his wife, Frances Harriet, on 13 November 1874: the letter is badly damaged.

Summary

Must stop work on "bloom" and leaf movements if he is ever to get anything published on Drosera, etc.

Sends thanks for seeds. Encloses memorandum in case WTT-D wishes to communicate information to Royal Horticultural Society. Has not time to prepare article.

Discusses condition of plants borrowed from Kew.

Summary

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.

Summary

The coral-reef book has been invaluable [J. D. Dana, Corals and coral islands (1872); used by CD in Coral reefs, 2d ed. (1874)].

Thanks for Saturday Review.

Summary

Huxley feels he can accept the Edinburgh lecture invitation.

Also tells JDH he is preparing a paper for Linnean Society on classification which will uphold evolution ["On the classification of the animal kingdom", J. Linn. Soc. Lond. (Zool.) 12 (1876): 199–226]. He has thrown overboard all his old ideas of definite demarcation. He will make a clean breast of it, and will bear hard on necessity of all such ideas as Haeckel’s in dealing with systematic zoology.

Summary

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.

Summary

Bishop J. W. Colenso supports his old contention that the Kaffirs (including Zulus of South Africa) are Negroes.

[Horace Waller’s] The last journals of David Livingstone [in central Africa (1874)] cites CD’s plant research and has many facts "for Darwin".
