Summary

Thanks for THH’s address [to Geological Society, Q. J. Geol. Soc. Lond. 25 (1869): 28–53]. Admires it and enjoyed attack on William Thomson hugely, but would tremble if he were in THH’s boots. Distinction made by THH between evolutionists and uniformitarians is too great. CD’s sentences on age of world in Origin will do, but he might have been less timid had he read THH.

Summary

Haeckel wants British specimens of calcareous sponges. Can THH tell him to whom he can apply?

Health not improving – cannot climb even a hill.

Has heard THH’s article on Comte ["Scientific aspects of Positivism", Lay sermons (1870)] is a splendid success.

Summary

Thanks for [D. D. Cunningham’s] letter. Had hoped for a better haul but delighted to hear of the curious fossil.

Summary

Last letter was written to be passed on for Lushington’s edification. "(Standing on the points of my toes and my tail very stiff)." Is tiring of controversy as a waste of time. Begins to understand CD’s sufferings over Origin.

Summary

Delighted with THH’s review [in Academy (1869)] of Haeckel’s [Natürliche] Schöpfungsgeschichte [1868],

but groans about THH’s view of rudimentary organs. Cites Origin and Variation.

Summary

Nothing new in Lushington’s letter. Two paragraphs are offensive – that THH sought to stir up Scotch Presbyterian prejudices against Comte at Edinburgh and that he had not read Comte.

Summary

Apologises for passing on what he agrees were offensive remarks in V. Lushington’s letter. Has told VL he had no right to make them. Asks THH to make allowance for red-hot disciples defending the master.

Summary

Has already referred Haeckel’s request to J. S. Bowerbank.

Has lost track of collectors and naturalists "by grace of the dredge" because of other work and ""the great question of "Darwinismus" which is such a worry to us all"".

Family health.

Summary

V. O. Kovalevsky, Russian translator [of Variation], wishes to hear THH lecture.

Summary

Will do his best on the tooth [sent by CD] but does not put much weight on conclusions based on a single tooth of a horse.

Darwin attacked by three clergymen at BAAS meeting [Exeter, 1869].

Summary

H. M. S. Nassau, surveying Magellan Straits, has found fossils at Gallegos River. They have been sent to THH by R. O. Cunningham [naturalist of H. M. S. Nassau]. Skull of entirely new ungulate mammal.

Summary

At writer’s request, forwards long letter on Comte by Vernon Lushington.

Summary

James Orton, U. S. naturalist, has sent him a tooth from skull of a horse found in Quito, Ecuador in deposits containing Mastodon, etc. JO asked CD to send it to Owen, but, since he does not communicate with Owen, he is sending it to THH.

Summary

Huxley has acknowledged receipt of VL’s letter. Both he and CD feel that some of VL’s statements were a little offensive although CD is sure this was not intended. Was glad to read the condensed statement of Comte’s claims in VL’s letter.

Summary

Huxley has shown him the jaws of an Anoplotherium brought from the Gallegos by R. O. Cunningham.

Saw Hallett’s wheat crops at Brighton; results of his selection very striking.

Huxley is assembling his Darwiniana papers for republication.

Has written a crushing reply to Richard Congreve ["The scientific aspects of positivism", Fortn. Rev. n.s. 5 (1869): 653–70] and JDH feels "infantine" beside him.

Comments on Sabine’s being offered and accepting K.C.B.

Summary

Interested in Barkly’s letter about Mauritius. Doubts non-volcanic origin. Urges collection of all forms of terrestrial life to determine whether they are of a former continent or "waifs and strays". He leans to latter view, as snakes and reptiles are different.

Huxley’s address wonderfully "brilliant", but it is a mistake to separate evolutionists from uniformitarians.

Bentham has come out "splendidly" on descent of species.

Summary

Suggests Englishmen who might provide sponge specimens.

Summary

Orchids translation should goad [French] Academy into electing CD.

JDH will be sent to St Petersburg congress by Government.

Huxley on protoplasm; his address to Geological Society.

Fertilised an Aucuba with pollen of various species. Reports on results.

Summary

Describes how the offer of C.B. was made. He declined a knighthood. Murchison and Lyell are trying to get him made Knight Commander of the Star of India, but he does not think there is a chance. The Duke [of Argyll?] might do it, but does not like JDH’s Darwinism.

Next Presidency of Royal Society discussed: all (Brodie, the X Club botanists, et al.) are agreed on Lyell.

Everyone is disappointed with Nature.

What did CD think of "Huxley’s rhapsody on Goethe’s ditto" [Nature 1 (1869): 9–11]?

Summary

Ernst Haeckel is working on calcareous sponges. Does AH have any British specimens that he can spare? [See 6842.]
