To Nature 22 February [1881]
Summary
Summarises the "remarkable facts about the movements of plants" in Fritz Müller’s letter of January [12996]. CD comments that Müller’s observations support the conclusion that he and Francis Darwin arrived at – that leaves go to sleep to escape the full effects of radiation.

To Nature 13 July [1881]
Summary
Communicates two cases of inheritance reported by J. P. Bishop [in 13137]. The work of E. Brown-Séquard has demonstrated that effects of injuries can be inherited ["Hereditary transmission of an epileptiform affection accidentally produced", Proc. R. Soc. Lond. 10 (1860): 297–8]. E. Dupuy has sent CD a still more remarkable case.

To Nature [before 15 September 1881]
Summary
Quotes from a Fritz Müller letter of 9 Aug supporting CD’s views that leaves position themselves at night so as to minimise heat loss by radiation. It is a new fact to CD that leaves take different positions at different seasons.

To Nature 7 November [1881]

Summarises letter of William Nation [13350]. The facts given strongly support the conclusion that there is some close connection between the parasitic habits of birds that lay their eggs in others’ nests and the fact of their laying eggs at "considerable intervals of time".
