Montauban, October 25th, 1864.

Busk and myself have made every effort to be back in London by the 27th inst., but we have been persecuted by mishaps—through the breakdown of trains, diligences, etc., so that we have been sadly put out in our reckoning—and have lost some of the main objects that brought us round by this part of France—none of which were idle or unimportant.

Busk started yesterday for Paris from Bruniquel, to make sure of being present at the meeting of the Royal Council on Thursday. He will tell you that there were strong reasons for me remaining behind him. But as I seconded the proposal of Mr. Darwin for the Copley Medal, in default of my presence at the first meeting, I beg that you will express my great regrets to the President and Council at not being there, and that I am very reluctantly detained. I shall certainly be in London (D.V.) by the second meeting on the 3rd proximo. Meanwhile I solicit the favour of being heard, through you, respecting the grounds upon which I seconded Mr. Darwin's nomination for the Copley Medal.

Referring to the classified list which I drew up of Mr. Darwin's scientific labours, ranging through the wide field of (1) Geology, (2) Physical Geography, (3) Zoology, (4) physiological Botany, (5) genetic Biology, and to the power with which he has investigated whatever subject he has taken up,—Nullum quod tetigit non ornavit,—I am of opinion that Mr. Darwin is not only one of the most eminent naturalists of his day, but that hereafter he will be regarded as one of the great naturalists of all countries and of all time. His early work on the structure and distribution of coral reefs constitutes an era in the investigation of the subject. As a monographic labour, it may be compared with Dr. Wells' "Essay upon Dew," as original, exhaustive, and complete—containing the closest observation with large and important generalisations.

Among the zoologists his monographs upon the Balanidae and Lepadidae, Fossil and Recent, in the Palaeontographical and Ray Societies' publications, are held to be models of their kind.

In physiological Botany, his recent researches upon the dimorphism of the genital organs in certain plants, embodied in his papers in the "Linnean Journal," on Primula, Linum, and Lythrum, are of the highest order of importance. They open a new mine of observation upon a field which had been barely struck upon before. The same remark applies to his researches on the structure and various adaptations of the orchideous flower to a definite object connected with impregnation of the plants through the agency of insects with foreign pollen. There has not yet been time for their due influence being felt in the advancement of the science. But in either subject they constitute an advance per saltum. I need not dwell upon the value of his geological researches, which won for him one of the earlier awards of the Wollaston Medal from the Geological Society, the best of judges on the point.

And lastly, Mr. Darwin's great essay on the "Origin of Species" by Natural Selection. This solemn and mysterious subject had been either so lightly or so grotesquely treated before, that it was hardly regarded as being within the bounds of legitimate philosophical investigation. Mr. Darwin, after twenty years of the closest study and research, published his views, and it is sufficient to say that they instantly fixed the attention of mankind throughout the civilised world. That the efforts of a single mind should have arrived at success on a subject of such vast scope, and encompassed with such difficulties, was more than could have been reasonably expected, and I am far from thinking that Charles Darwin has made out all his case. But he has treated it with such power and in such a philosophical and truth-seeking spirit, and illustrated it with such an amount of original and collated observation as fairly to have brought the subject within the bounds of rational scientific research. I consider this great essay on genetic Biology to constitute a strong additional claim on behalf of Mr. Darwin for the Copley Medal. (180/2. The following letter (December 3rd, 1864), from Mr. Huxley to Sir J.D. Hooker, is reprinted, by the kind permission of Mr. L. Huxley, from his father's "Life," I., page 255. Sabine's address (from the "Reader") is given in the "Life and Letters," III., page 28. In the "Proceedings of the Royal Society" the offending sentence is slightly modified. It is said, in Huxley's "Life" (loc. cit., note), that the sentence which follows it was introduced to mitigate the effect:—

"I wish you had been at the anniversary meeting and dinner, because the latter was very pleasant, and the former, to me, very disagreeable. My distrust of Sabine is, as you know, chronic; and I went determined to keep careful watch on his address, lest some crafty phrase injurious to Darwin should be introduced. My suspicions were justified, the only part of the address {relating} to Darwin written by Sabine himself containing the following passage:

"'Speaking generally and collectively, we have expressly omitted it {Darwin's theory} from the grounds of our award.'

"Of course this would be interpreted by everybody as meaning that after due discussion, the council had formally resolved not only to exclude Darwin's theory from the grounds of the award, but to give public notice through the president that they had done so, and, furthermore, that Darwin's friends had been base enough to accept an honour for him on the understanding that in receiving it he should be publicly insulted!
