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

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

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

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

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

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

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

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

Is delighted at the sale of Descent. What CD says about her help pleases her very much and the proposed gift as a memorial will be very precious to her. Is looking forward to seeing the family in London. Comments on a letter comparing CD's appearance to an ape. Is surprised CD has had no effect on Wallace: 'It seems to me his mind can’t be so clear as u used to think it'. Has worked out why she is dissatisfied with T. H. Huxley's essay ‘On the physical basis of life’ (T. H. Huxley 1869).

Summary

Suggests Englishmen who might provide sponge specimens.

Summary

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

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

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

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

Sends 6th ed. of Origin;

draws attention to his criticism of ARW’s estimate of Kovalevsky;

mentions his disagreement with much of Spencer’s doctrine

and in a postscript points out an inaccuracy in an article in Once a Month.

Summary

On THH’s review [see 7977] of Mivart’s Genesis of species and the Quarterly Review article on Descent.

Summary

Lady Lyell has died of typhoid.

Herbert Spencer is anxious to know about the state of affairs [fund for Huxley].

Edinburgh Review article [review of Expression, Edinburgh Rev. 137 (1873): 492–528] is "a thoroughly nasty unfair review as ever I read".
