Encloses a letter from a Mr Hill on some [unspecified] legal matter.
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.
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.
Thanks CD for financial assistance for Mr Fitch and his wife.
Advises his children as to how some money will be distributed among them.
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.
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.
