In an article in Das Ausland, Zacharias explains CD’s objections to a theory of heredity outlined by Marcus Cohen. The text is an excerpt from CD’s letter to Zacharias on the subject.

Summary

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

Summary

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.]

Summary

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].

Summary

Cancelled: part of 11847

Summary

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

Summary

Thanks for a copy of Insectivorous Plants.

Summary

At last, Expression is beginning to sell again.

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

Summary

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

Summary

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

Summary

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

Summary

He has confuted Descent.

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

Summary

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.

Summary

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

Summary

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.

Summary

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

Summary

Sends copy of Arabische Korallen [1876].

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

Summary

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.

Summary

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.
