Thanks for specimens [of insects].

Wonders whether difference between male and female plays part in fertilisation of fig.

Flowers of Oxalis sensitiva, sent long ago, are trimorphic and cleistogamic.

Had found out his error [use of "cleistogenous" for "cleistogamous" in Cross and self-fertilisation] some timeago.

Is now writing on cleistogamic flowers [for Forms of flowers (1877)], and, with it, will have worked up all his old materials on plants. JVC will then have a rest from his labours of translation.

Thanks for the reviews, particularly the one in the Times.

CD will be pleased to receive Mr Wallace.

Regrets he cannot permit his name to be used to support WSK’s aquarium project. If WSK decides to set up an aquarium solely for scientific purposes he would consider subscribing.

Sends autograph as requested.

Is "awfully glad" at LD’s appointment [as an instructor at Chatham].

Thinks LD should start reading chemistry "though reading does not do much".

Reports scientific work of George and Frank Darwin.

"Charles Darwin Down, Kent April 2d. 1877; With Mr Darwin’s compliments. – "

Thanks for Saxifraga. CD had shown in Insectivorous plants [pp. 345–7] that this genus had some powers of absorption.

Thanks for membership of Zeeland Scientific Society at Middelburg.

Thanks GHL for a copy of his Physical basis of mind [1877].

CD regrets not being able to see JDH.

"Frank has sent the cards here."

Thanks for ESM’s address ["What American zoologists have done for evolution", Proc. Am. Assoc. Adv. Sci. 25 (1876)].

J. A. Allen’s work is important as apparently showing change through direct action of [external] conditions.

CD has given up trying to understand E. D. Cope and Alpheus Hyatt on acceleration and retardation.

Discusses locks and window-fastenings, which CD has discovered are not included in the contract for alterations to the house at Down, and a cornice in a passage-way..

CD has sent the pig’s foot to William Henry Flower to examine.

CD submits his paper ["A biographical sketch of an infant", Collected papers 2: 191–200] for possible publication.

Thanks for GOS’s memoir on Brisinga [1875].

Is honoured by CGS’s dedication [see 10942].

His observation of the dorsal eyes of Onchidium is interesting and surprising.

Thanks for a copy of VC’s Théorie du Fatalisme (Theory of fatalism; Conta 1877).

Has not yet heard from Cambridge. Thinks perhaps they do not intend to give him the degree.
