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

Prof. Wood-Mason has examined Otto Zacharias’ insect photographs and confirmed the genera.

RM is going to work up Fritz Müller’s observations into a paper.

Summary

Observations on a sensitive Mimosa.

Comments on structure and positioning of "odoriferous organs" of moths and butterflies,

and feeding habits of butterfly larvae.

Summary

Describes his talk with Julius von Sachs about canary-grass.

Summary

Would like to read Weismann’s essay on Daphnidae.

Fritz Müller’s paper on odours emitted by butterflies was read at last Entomological Society meeting.

Summary

Thanks for letter. CD now has all the seeds and information he requires.

Value and origin of amphicarpic habit.

Summary

Thanks HM for his review [of Forms of flowers, Kosmos 2 (1877–8): 286].

Thinks HM’s previous article was very important [Kosmos 2 (1877–8): 128–40]. CD will "heartily rejoice" if HM has explained the steps by which Rhamnus and Valeriana have been rendered dioecious.

Summary

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

Summary

Reports results of crosses between the two forms of Viola tricolor: 1. Female small flower crossed with male large flower yields all small flowers (cleistogamous self-fertilisation suspected); 2. Male small flower crossed with female large yields intermediate flowers; 3. Large flower crossed with large flower yields self-sterility symptoms.

Summary

Reports butterfly species that apparently mimic each other and gives details of some odoriferous species.
