Summary

Writes, as editor of the Intellectual Observer, saying how much he would like to be able to publish papers by CD.

Summary

Encloses memorandum on Origin [1866]

discussing mimicry in mammals and birds,

abnormal habits shown by birds,

behaviour of cuckoos,

and analogies existing between mammals of the same geographical region.

Speculates on possible lines of development linking groups of mammals.

[CD’s notes on the verso of the letter are for his reply.]

Summary

CD is delighted that JVC will undertake translation of Variation.

Agrees with JVC’s opinion of Haeckel’s book [Generelle Morphologie (1866)]. CD believes it is bad policy for Haeckel to speak so positively about a disputed theory [i.e., CD’s] and particularly regrets the severity of EH’s criticisms of other authors.

Summary

Sends copy of book containing measurements taken of individuals of different races during voyage of Novara [Karl Heinrich von Scherzer, ed., Reise der Fregatte "Novara", Anthropologischer Theil (1867)].

Asks for scientific advice concerning newly planned expedition.

Says Carl Vogt plans to use data from book in lectures.

Summary

Would be great honour to have CV translate Variation, but Schweizerbart has arranged for J. V. Carus to do it.

Has read CV’s Lectures on man [1864] with extreme interest.

Summary

Discusses hybridisation in cowslip and primrose.

Mentions proposed visit.

Summary

Discusses dimorphism in plants, especially the Rubiaceae.

Gives observations on orchids; notes varying degrees of self-sterility and a varying success at crossing distinct species.

Mentions local ferns he is collecting

and considers the phenomenon of apparently mimetic plants.

Summary

Thanks JVC for his biography [of CD].

Has almost finished first proofs of Variation.

Has difficulty in answering JVC’s queries about dogs because of differences in German names and breeds. Refers him to A. E. Brehm’s Illustrirtes Thierleben [1868] and, on pigeons, to Gottlob Neumeister’s book [Das Ganze der Taubenzucht (1837)].

Hopes JVC is not discouraged by first volume. Thinks second will be more interesting.

Summary

Answers CD’s queries about polygamous birds. Does not think appearance of cock makes any difference to female. Dyeing the male has no effect on female.

Summary

Requests information about rudimentary muscles and organs in man. Asks about marrow of os coccyx, and about testes and ovaria in early embryos of both sexes.

Summary

Is engaged to marry Agnes Huschke. Will make wedding trip to Switzerland and Italy in autumn; therefore cannot visit CD as hoped.

Sends photograph of Viennese botanist, August Kanitz.

Summary

Working on sexual differences in collection of horned beetles and will send CD results.

Answers CD’s questions [sent on behalf of Miss Tollet of Betley Hall, Staffs.] on mimicry – how it helps prevent extinction, the modifications occurring with a change of habitat until mimicry occurred.

Also gives some cases of sexual differences.

Summary

Will not attend the British Association meeting at Dundee.

Summary

Schweizerbart anxious to get Variation sheets for German translation. Hopes he has found a good indexer in W. S. Dallas.
