Summary

Good article by Fritz Müller in Kosmos supporting August Weismann’s views on caterpillars.

Summary

Is dispatching December number of Kosmos.

Will read the discussion on stridulation that RM mentioned.

Summary

Thinks there can be no objection to RM’s using a Fritz Müller letter [see 11319].

Summary

Thanks RM for his interesting paper ["Entomological notes bearing on evolution", Ann. & Mag. Nat. Hist. 5th ser. 1 (1878): 155].

Summary

Asks RM to send a copy of the Entomological Society’s Proceedings to Fritz Müller.

Summary

Thinks RM may like to see the enclosed [Fritz Müller letter].

Summary

Would like to have some insect photographs identified; they seem to show pretty and new case of protective resemblance.

Summary

Encloses Fritz Müller letter, which may be of interest [see 11463].

Summary

RM should take no more trouble over the subject [Otto Zacharias’ photos; see 11510].

Summary

Is glad RM will draw up a paper from Fritz Müller’s letter.

Summary

Has received interesting essay from August Weismann on sexual selection in daphnoids [“Schmuckfarben der Daphnoiden”, Z. Wiss. Zool. (1878)].

Summary

Does not think the Petunia is anything remarkable.

Summary

Will do his best to provide preface for Weismann’s Studien [see Collected papers 2: 280–1].

Summary

Invites RM to luncheon.

Summary

CD sends his preface [to RM’s translation of August Weismann, Studies in the theory of descent (1882); Collected papers 2: 280–1].

Summary

Regrets he cannot compare his work with Weismann’s in his preface as he feels “an author is never a fit judge of his own work”. [Appended note explains that RM wished CD’s work to be fully acknowledged, which was frequently not the case in continental writings.]

Summary

Is glad book progresses; answers translation query.

Francis Darwin does not have time to lecture.
