Summary

Has finished ACR’s article ["The old glaciers of Switzerland and N. Wales" in Peaks, passes, and glaciers, ed. J. Ball (1859)]. Asks the authority for glacial drifts in Siberia. Wishes ACR would examine the Glen Roy parallel roads and settle the problem.

Asks if it is certain that traces of organic remains have been found in Long Mynd beds.

Summary

Wallace has written and is well satisfied with the joint presentation.

CD requests some facts to make case in his abstract for former glacial action in Himalayas.

Summary

Discusses affairs at Down and WED’s coming trip to the Lakes.

Is getting on very slowly with his "confounded proof-sheets" [of Origin].

Summary

High, detailed praise for introductory essay to Flora Tasmaniae [reprinted as On the flora of Australia (1859)]. CD expects it to convert botanists from doctrine of immutable creation.

Summary

Discusses P. S. Pallas’ theory of origin of domestic dog breeds. CD believes domestic dogs descended from more than one aboriginal wild species but ultimately "we believe all canine species have descended from one parent and the only question is whether the whole or only part of difference in our domestic breeds has arisen since man domesticated them".

Races of man offer great difficulty. The doctrine of Pallas and Agassiz that there are several species "does not help us" in the least.

Hopes Henry Holland will not review Origin.

CD’s and CL’s difference on "principle of improvement" and "power of adaptation" is profound. Improvement in breeds of cattle requires neither. Urges him to reread first four chapters of Origin carefully. Natural selection is not to be contrasted with "improvement": every step involves improvement in relation to the conditions of life. There is no need for a "principle" to intervene.

Summary

CD will not write to L. Descaisne to defend his priority over C. V. Naudin.

Feels success of theory depends on acceptance and application by good and well-known workers, like JDH, Huxley, and Lyell.

Summary

Sends payment for Francis Darwin’s tutoring. Inquires about possible arrangements for his son Leonard, who is slow and not well, to attend with Francis.

Asks whether he can have a cutting of GVR’s carrion-smelling Arum which he needs for an experiment.

Summary

CD is astonished at sale of Origin [to booksellers].

Arranges to start new edition immediately. Cannot change much [while at Ilkley Wells], nor work rapidly because of health. Relieved that JM has no cause to repent of publishing Origin.

Summary

Requests one-half dozen dead bees and 2 or 3 drones from Mr Wilkie’s stock.

His admiration for RH’s varied accomplishments and service "in the sacred cause of humanity" [the abolition of slavery].

Asks whether it is believed that domestic animals long bred in Jamaica tend to assume a particular colour or character.

Are differences observed in the West Indies in the liability of pure Europeans of light complexion and hair to take the yellow fever or other tropical complaints?
