Summary

Asks for a note about sling for Leonard’s arm, as he is about to leave for school.

Summary

Thanks AG for his trouble about expression queries; wishes he had thought earlier of having them printed.

Is "plodding on" correcting Variation

and getting "a little amusement" from plant experiments. Oxalis is trimorphic like Lythrum.

Is continuing his experiments on seedling vigour.

Has heard hybrid potatoes can be produced by joining halves of different tubers.

Summary

On whether to make woodcuts for Variation in Russia or use Murray’s stereotypes. He has similar advance publication agreements with Carl Vogt, E. A. Rossmässler and Theodor Billroth.

The Russian version of Origin is translated from Bronn’s German edition.

Summary

Cites cases of difference in coloration between the sexes of some species of Crustacea, annelids, and spiders.

Discusses dimorphic plants and self-sterility.

Outlines some experiments involving the crossing of different species of orchids.

Encloses extract from Carl Claus, Die freilebenden Copepoden [1863].

Summary

Thanks for "Climbing plants" offprint and for references on fertilisation of flowers.

Considering the bounty of work already done, he is looking for something original to do.

Subularia does not grow in Westphalia.

Summary

Asks if he should give the clichés of Variation to E. Schweizerbart.

Summary

Begins to hope baby may survive; description of symptoms.

Summary

Will find out identity of Robert Trail.

Summary

Rejoices over baby’s improvement.

Horace Darwin has intermittent fever.

Thanks JDH for page of the Farmer, a great service.

R. Trail’s potato grafting case would be of extreme value for demonstrating Pangenesis. [See Variation 1: 395.]

Summary

Asks JM not to send stereotypes [of Variation] to Schweizerbart until he has heard that Carus will translate it.

Summary

Congratulates TB on his son’s success in scientific studies.

Susan Darwin’s death [Oct 1866] has severed last ties of family with Shrewsbury.

Summary

C. Nägeli’s long letter on his four years of work on Hieracium appears to be valuable. Nägeli wants a set of British forms in exchange for German ones.

Sends note on a new genus of Umbelliferae (Drusa) in Canaries; speculates on origin.

Summary

JVC is willing to translate [Variation], especially because of his conviction that progress of biology depends on proving CD’s theory.

Ernst Haeckel’s book [Generelle Morphologie (1866)] will do mischief because EH is so immoderate. Suggests CD tell EH that he has done him a bad service. CD is the only one to whom EH would listen.

Summary

Reports on an experiment in crossing potato varieties.

Summary

JDH has left for Paris with Thomas Thomson.

Baby is better.

Summary

Sends Oliver’s list of references on Adoxa.

Baby now out of trouble.

Pleased with Paris exhibition.

Summary

Arrangements for obtaining Carl Nägeli a set of British Hieracium specimens.

Summary

Asks whether he may have right to translate Variation into German.

Summary

Thanks for his long letter on morphological laws.

Summary

CD writes about stereotypes for German and Russian editions of Variation.
