Plans for his new book, Contributions to the theory of natural selection (1870), which will contain his papers on the subject.

Response to ARW’s MS on geological time ["The measurement of geological time", Nature 1 (1870): 399–401, 452–5].

Groans over [what is said about] man.

Would like to call at 10 o’clock on Wednesday morning.

Thanks for a woodcut sent by ARW for Descent.

Congratulations on his removal from London,

and praise of his review of Francis Galton ["Hereditary genius", Nature 1 (1870): 501–3]. CD agrees with every word of it.

Appreciation of eulogy in preface of ARW’s book [Theory of natural selection].

CD sends a "curious drawing" [missing] relating to imitation and protection.

Thanks for the drawing.

E. Claparède’s review [of Theory of natural selection, Rev. Cours Sci. 7 (1870): 564–71] is weak.

Looks forward [to Descent] with fear of being "crushed under a mountain of facts!"

Praise for ARW’s reply [Nature 3 (1870): 49–50] to a paper by A. W. Bennett ["Natural selection from a mathematical point of view", Nature 3 (1870): 30–3] holding that mind is a leading cause of variation.

Is reading proof of his "confounded book" [Descent].

On a good criticism of ARW’s views [North Am. Rev. (1870)].

Problems of establishing a permanent residence.

His Presidential Address for Entomological Society will answer A. Murray on geographical distribution of Coleoptera.
