Is doubtful about the publication of Fritz Müller’s letter after so long an interval.

Thinks the facts in Fritz Müller’s letter could be published.

Recommends August Weismann’s essay on dimorphism ["Über den Saison-Dimorphismus der Schmetterlinge", Studien zur Descendenz-Theorie 1 (1875)]

and has no doubt that intermediate forms could be eliminated as RM suggests.

Does not think Fritz Müller can object to anything RM has said in his essay.

Has alluded to colour preference among butterflies in Descent [1: 400–1].

Interesting article by Fritz Müller on sexual selection in butterflies, Kosmos [1 (1877): 388–95].

Thinks Weismann would welcome a translation.

Was dissatisfied with Wallace’s article.

Hopes RM finds a publisher [for his translation of Weismann’s Studien].

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

Is dispatching December number of Kosmos.

Will read the discussion on stridulation that RM mentioned.

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

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

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

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

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

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

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

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

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

Does not think the Petunia is anything remarkable.

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

Invites RM to luncheon.
