Encloses "account of Dr H. M. Butler’s hereditary odd habit".
Interested to hear about the peas.
Thinks CD’s case of twins with crooked fingers may be one from his twin study.
Sends a lecture CD wished to see
and corrects himself about the twins.
Outlines a memoir he will give at the Anthropological Society in which he differs theoretically with Pangenesis.
Sends a proof of his "Theory of heredity" from the Contemporary Review [27 (1875): 80–95; revised in J. Anthropol. Inst. 5 (1876): 329–48]. Welcomes CD’s help and criticism.
Responds to suggestions and criticisms CD made to "theory of heredity" [see 10245].
Thanks for the peas which arrived in "beautiful order".
Outlines in simple form the statistical distribution of inherited characteristics in a theory of "organic units".
Gives further explanations of his theory of stirps and his objections to Pangenesis, in answer to a question of CD’s.
Thanks FG for his report [on the statistical validity of CD’s experiments; see Cross and self-fertilisation, pp. 16–18]. Discusses FG’s comments, his own experiments, and the means by which the results may be analysed.
Sends packets of seeds of peas of different sizes [i.e., weights] for CD’s experiments; identifies size of the seeds that produced them. FG is experimenting "in the same direction" and is curious how his results will compare with CD’s.
Gives another instance of curious habit in the Butler family.
Attributes the Castilian accent of speech of deaf and dumb men to imitation of their teachers’ lip movements.
Sends some "composite portraits", including three of their family ancestors, as described in Nature [18 (1878): 97–100].
Conveys some information about Dr Erasmus Darwin’s second wife and discusses photos of him and his wife.
Memorandum about Dr Erasmus Darwin’s bequests.
Praises CD’s biography of Erasmus Darwin;
asks CD to answer some queries he is circulating. Is particularly interested in "visualizing faculty" in CD and Dr Darwin.
On colours and breeding of rabbits.
Interim report on the experiments with rabbits [to test Pangenesis].
