Asks JDH to consult colleagues learned in physiology for answer to query: when a large piece of bark is removed from a tree, does the bark ever regrow in isolated points [separate] from the growing margin of the surrounding bark? Query bears on Pangenesis and on power of repair in plants.
JM is about to start a new monthly literary review [the Academy]. Would like to publish in first number a short notice of the new work upon which CD is engaged [Descent].
Asks CD’s opinion of a paper he has written on papilionaceous flowers.
Leaflet variation at the tip of Lathyrus stems.
Wishes JM’s new periodical [the Academy] could have been a weekly so it might kill the Athenæum by a lingering death.
Has drafted a piece [about Descent] but is not pleased with it.
James Orton, U. S. naturalist, has sent him a tooth from skull of a horse found in Quito, Ecuador in deposits containing Mastodon, etc. JO asked CD to send it to Owen, but, since he does not communicate with Owen, he is sending it to THH.
Robert Fenn exhibited potatoes at the Horticultural Society which showed general failure of graft-hybrids and provided an example of reversion to a wild Peruvian tuber resulting from cross-fertilisation.
Sends a list of queries for AG.
Asks whether AG can supply specimens for illustrations [for Descent]. Hopes Mr Ford will do the drawings.
Thanks CD for the English edition of his brother’s book [Fritz Müller, Facts and arguments for Darwin (1869)]
and for CD’s memoir on orchids ["Fertilization of orchids", Collected papers 2: 138–56].
Sends notes on variation in plants.
Mr Ford is attending to CD’s drawings [for Descent].
Death of AG’s wife.
Time of his arrival.
Will bring bark story with him.
Thanks for a paper on phyllotaxy.
Is "astonished & deeply grieved" at loss [of AG’s wife].
Replies to CD’s queries on sexual habits and differences in fish and lizards.
Thanks AR for specimens and notes. Will keep them for future edition [of Variation]. Particularly struck by difference in hardiness of varieties of Syringa persica.
Thanks AG for full answers to queries.
Delighted Mr Ford will undertake drawings [for Descent]; comments on some illustrations he would like.
Will do his best on the tooth [sent by CD] but does not put much weight on conclusions based on a single tooth of a horse.
Darwin attacked by three clergymen at BAAS meeting [Exeter, 1869].
Reports on the differences of growth and development of plants of three species grown at Geneva from seed collected at different localities. Forwards seed for CD to plant and observe differences in development.
Carl Linsseer has published a memoir on the times of flowering, foliation, etc. of diverse species in different parts of Europe [Mem. Acad. Imp. Sci. St.-Pétersbourg 7th ser. 11 no. 7 (1868)] and concludes that the northern forms are more forward and that this is hereditary. AdeC’s experiments carried out on annuals, show only the effects of heredity; probably the direct action of physical conditions affects development, at least in perennial species.
