In answer to CD’s query, FM thinks the seeds he sent were those of the sensitive Mimosa.

Reports his observations of movement of leaves of Bauhinia grandiflora and B. brasiliensis. They do not "sleep" in hot weather.

Sends some seeds of Pontederia he had fertilised.

Thanks CD for letter for Villa Franca. Would be happy if CD published the Baron’s observations in an English scientific journal.

Reports the inconclusive results of some experiments he has been doing for CD [related to plant colouring material?].

Has sold London & South Western Railway stock and has purchased Great Western stock.

Thanks CD for financial assistance for Mr Fitch and his wife.

Has read Earthworms; discusses parts and encloses a list of errata. Writes of worm-castings, describing his observations; speculates on the variation in their distribution under different conditions.

Praises G. H. Darwin’s letter ["On the geological importance of the tides", Nature 25 (1882): 213–14] which criticises the use made of George Darwin’s views by Robert Ball ["A glimpse through the corridors of time", Nature 25 (1881): 79–82, 103–7]. JWJ argues from the fineness of Cambrian sediments against Ball’s intensification of geological forces. Massive Carboniferous river deltas also contradict Ball’s excessively high tides.

CD’s division of his surplus income; fire engines; Sara Darwin’s relatives; GHD’s paper in Nature.

Thanks CD for Earthworms.

Discusses the problem of accounting for difference between nitrogen in permanent grassland and ordinary arable soil. Finds castings of earthworms rich in nitrogen. Asks CD if his observations enable him to explain the source. If from below top-soil, it would be a considerable manuring.

Sends his paper on the comparative anatomy of the assimilatory tissue systems of plants [Jahrb. Wiss. Bot. 13 (1882): 74–188]. This work has made clear to him how CD’s principles produce rich results when applied to plant anatomy.

Also sends a paper on the difficult problem of the gulf between cryptogamic and phanerogamic plants in the evolutionary development, in order to present another proof of the continuity of the phylogenetic development of the plant kingdom.

Wishes to borrow Weismann’s pamphlet on the Daphnidae [ "Ueber die Schmuckfarben der Daphnoiden", Zeitschrift für wissenschaftliche Zoologie 30 (Supp.)]. Is preparing an essay on "alternation of generations".

B. D. Jackson’s plan for new Steudel Nomenclator approved. JDH asks for CD’s cheque.

Sends CD some of the [American Social Science] Association’s publications; asks if they may enrol him as a corresponding member. They have printed CD’s letter to Mrs Talbot

and also his paper from Mind (1877) ["Biographical sketch of an infant"].

Discusses a lectureship at Aberdeen

and a recent visit to Down.

Potatoes [from Torbitt experiment] sent him for eating were very poor. Those for seed produced abundantly, but have not resisted disease better than other kinds that Payne [his gardener] has grown.

Sends article on dimorphism in Oxalis violacea [Am. Nat. 16 (1882): 13–19].

Encloses an extract (from the Bayswater Chronicle [missing]), which is part of an ongoing disagreement in which JFS is involved.

Has read some references to CD’s hypothesis on music and offers a MS by himself which deals with the subject.

Has ordered a tin of Somerset Mixture snuff for CD.

The Secretary to the First Commissioner of Her Majesty’s Works thanks CD for providing the funds for a new edition of Steudel’s Nomenclator [Index Kewensis].

Sends a translation of Aristotle’s De partibus animalium and imagines that if the old teleologist were alive CD would convince him of his errors.
