Summary

Thanks for photographs [of German scientists].

Summary

Discusses exchange of photographs with German scientists.

Comments on attitudes of German scientists toward CD’s theory.

Names several scientists who exchanged photographs: Braun, Virchow, Leydig, and Dohrn.

Summary

Thanks EH for album of photographs of German scientists.

Summary

Sends album of photographs of German scientists as birthday honour.

Summary

Has read in the newspapers about the album of photographs of German scientists sent in tribute to CD. His name and photograph are missing only because he was not asked to participate. CC assures CD he is one of his ardent supporters.

Summary

Ernst Haeckel writes that young German scientists are enthusiastic for natural selection.

Did JDH write the article in Natural History Review on trees not producing flowers ["Botanical lesson books", (1864): 355–69]?

Encourages Harvey to publish on his "disagreeable" monster plants.

Summary

CD doubts that he will be able to do much more that is new, but cannot bear idleness. Has great amount of material on variation under nature, but so much has been published since the appearance of the Origin that he doubts he has the power of mind to render the mass into a digested whole.

Summary

Congratulates CD on testimonials from the savants of Germany and the Netherlands [Nature 15 (1877): 356, 410–12] and generally on his contributions to biology.

Asks if and when CD’s "Variability of organic beings in a state of nature", as projected in 1868 [see Variation 1: 4] is to appear.

Summary

Thanks for paper ["Über die Entwicklungstheorie Darwins", Amtl. Ber. Versamml. Dtsch. Naturforsch. Aerzte 38 (1863): 17–30]. Delighted EH confirms his views. Many in England afraid to express views openly.

Summary

Comments on CD’s health.

Discusses origin of life and differentiation of principal classes of plants and animals.

Discusses Generelle Morphologie and its chapter on embryological development.

His lectures on CD’s theory.

Asks CD for larger portrait of himself and for several copies of the small photograph. Will send photographs of German scientists in exchange.

Summary

A curious error – too late to change: in Cross and self-fertilisation CD has "cleistogenous" for "cleistogamous" flowers throughout.

Summary

Distribution of plants.

Removal of posterior molars a common dental practice in America [see Descent 1: 27].

Summary

Sends copies of photographs of himself. Asks for photographs of German naturalists.

Comments on EH’s account of Protogenes primordialis.

Summary

No book has made such a powerful impression on EH as the Origin. Most older German scholars opposed to it, but number of supporters growing among the young. Fortunately strength of religious dogmas now small among educated Germans. Situation in Jena especially favourable. Defended CD’s theory last year at Congress of German Scientists in Stettin.

Intends special study of jellyfish.

Plans general work on natural history.

Hard fate [death of Anna Sethe Haeckel] has made EH indifferent to criticism.

Colleagues August Schleicher and Carl Gegenbaur also convinced by CD’s theory.

Summary

Believes that he has an important physical theory: all atoms revolve.
