Thanks for PPCH’s ["Entwicklungsgeschichte der Entomostraken, pt 1: Embryologie von Balanus", Niederl. Arch. Zool. 3 (1876–7): 47–82].

Comments on Weismann’s remarks on the possibility of sexual selection in the genus Daphnia.

A. R. Wallace has published paper giving up sexual selection [Review of St George Jackson Mivart’s Lessons from nature, as manifested in mind and matter.] in Academy, 10 and 17 June 1876, pp. 587–8.]

Has received a baffling article on God, immortality, and socialism under a Darwinian point of view.

Clerk Maxwell has disagreed with CD on molecular calculations in relation to Pangenesis in Encyclopaedia Britannica article ["Atom", Encyclopaedia Britannica, 9th ed. (1875) 3: 36–49].

Complies with correspondent’s request; encloses photographs of himself.

Thanks for the copies of the Garden, which contain a drawing of CD and notice of his work.

Thanks for a copy of Insectivorous Plants.

At last, Expression is beginning to sell again.

Cooke has not yet decided on number of Variation [2d ed.] to print.

Asks GHD to calculate average or mean heights of crossed and self-fertilised plant species.

Provides CD with a method of obtaining a numerical ratio that expresses the superiority in heights of crossed plants to self-fertilised plants.

Accepts WR’s offer of copies of the Garden for the next half-year.

He has confuted Descent.

Enclosures announce his cures of potato blight, epilepsy, etc.

Has confirmed CD’s observations on Drosera.

Asks whether CD agrees that it is "no longer a fact" that the bladders of Utricularia vulgaris enable the plant to become lighter for fecundation and heavier when that act is accomplished. Plans to undertake further observations, under very high-powered microscopes, of mechanism of digestion.

Bug on Tilia, cited in Variation, was Cimex apterus.

CD has read all of WHD’s and J. J. Drysdale’s papers [on spontaneous generation, monads, and the origin of life] and finds them the best work on the subject.

The function of bladders in Utricularia is not to float the plant.

Two photographs of T. W. Clarke, Jr, aged three, offered as examples of expression.

Sends copy of Arabische Korallen [1876].

Comments on reception of his paper on "Gastrula" [see 10012].

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.

Has sent his paper on Echinoidea [see 10373] as a token of his veneration. He tried to address the confusion in knowledge about the different parts of the exoskeleton of the Echinodermata by tracing certain relations of homology not previously noticed. Much more work is required.

Thanks EH for Arabische Korallen [1876].

Reports on the tendency of the normally fruitless Convolvulus arvensis, to form fruit when roots are cut and plant is in danger of dying.
