Has some Utricularia minor for CD. Has found the bladders on U. vulgaris are not floats.
Thanks CD for book [Descent, 2d ed.].
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.
Sends results of his observations on Nepenthes. Would be grateful for any hints for further observations.
Will do experiments CD suggests.
Is sending his book on the poisonous snakes of India [The Thanatophidia of India (1872)].
Thanks for proofs [of Descent, 2d English ed.].
Publisher would like better photographs for Expression [2d German ed.].
The appetite of Nepenthes for hard-boiled egg is prodigious.
Sends quotation from R. C. Virchow which contravenes CD’s statement in Expression that there is no voluntary control of the iris.
Sends specimens of Pinguicula and observations made on them. [See Insectivorous plants, pp. 390–1.]
Reports results [partly excised] of examination of fibro-cartilage subjected to artificial gastric juice and to Drosera secretion. [See Insectivorous plants, pp. 104–5.]
Sets out some of his ideas on the effects of disuse on an organ. Disuse as a cause of reduction.
On hearing of CD’s work with Drosera, tells of his experiment showing extreme sensitivity of the iris of a dog’s eye to atropine. [See Insectivorous plants, p. 173.]
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.
She and her father have been counting insect remains on Pinguicula hairs.
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]?
WED encloses a letter from H. M. Wilkinson about Utricularia and sundew.
H. M. Wilkinson has examined bladders of Utricularia; doubts that they absorb or digest insects.
H. M. Wilkinson describes dragonfly trapped by sundew [Drosera].
Thanks CD for Coral reefs [2d ed. (1874)].
JDD will correct his misunderstanding of CD on one point in the next edition of his book [Corals and coral islands].
Suggests CD consult Charles Wilkes’s Narrative [1844] for more accurate observations on Pacific islands.
Thanks for CD’s son’s observations
and for allowing DAS to visit Down.
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.
Is glad CD approves of his book;
has not yet done any more experiments on snake poison.
Encloses a tracing of a portrait of John Bunyan showing the differences of the two sides of the face.
