Summary

Has reread copy of Fritz Müller’s letter that CD sent some time ago and would like to publish the entomological observations in it.

Summary

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

Summary

Encloses Fritz Müller’s letter.

Is exhibiting butterflies in which variations in the female show a finely graded series. Believes dimorphism can be explained by the selection of the extremes of such a series and the consequent extinction of the intermediates.

Summary

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.

Summary

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].

Summary

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

Summary

Would like to see the Kosmos article.

Is considering producing a translation of August Weismann’s essays.

Comments on Wallace’s paper on the colours of animals and plants [Macmillan’s Magazine 36 (1877): 384–408, 464–71].

Summary

Thinks Weismann would welcome a translation.

Was dissatisfied with Wallace’s article.

Summary

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

Summary

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

Summary

Wishes to borrow third part of Fritz Müller’s article on sexual selection in butterflies [Kosmos 2 (1877–8): 218–24].

Is forwarding material on stridulation, including Prof. Wood-Mason’s paper ["Note on Mygale stridulans", Trans. R. Entomol. Soc. Lond. (1877): 281–2], which should interest CD.

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

Returns Kosmos.

Thanks CD for permission to use Fritz Müller’s last letter, which contains new observations.

Summary

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

Summary

Encloses proof of the Entomological Society’s Proceedings for February to show the use he has made of Fritz Müller’s letter [see 11319].

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

Will exhibit the photos at the Entomological Society and have them identified.

Fritz Müller’s observations on relative abundance of mimicking and mimicked species.
