It is interesting to be able to infer from Lyell's accounts of these days, that the sagacious De la Beche was beginning to weaken in his opposition to evolutionary views, and that Fitton and John Phillips were inclined to support him, but neither of them was ready to come forward boldly as the champions of unpopular opinions. John Herschel, who sympathised with Lyell in all his opinions, was absent at the Cape, Scrope was absorbed in the stormy politics of that day, and it was not till Darwin returned from his South American voyage in 1838, that Lyell found any staunch supporter in the frequent lively debates at the Geological Society. It is pleasing, however, to relate that this strong opposition to his theoretical teachings, did not lessen the esteem, or interfere with the friendship, felt for Lyell by his contemporaries. During all this time he held the office of Foreign Secretary to the Society, and in 1835 was elected President, retaining the office for two years. The general feeling of the old geologists with respect to Lyell's opinions was very exactly expressed by Professor Henslow, when in parting from young Darwin on his setting out on his voyage, he referred to the recently published first volume of the _Principles_ in the following terms:-- 'Take Lyell's new book with you and read it by all means, for it is very interesting, but do not pay any attention to it, except in regard to facts, for it is altogether wild as far as theory goes.' (I quote the words as repeated to me by Darwin, in a conversation I had with him on August 7th, 1880, of which I made a note at the time. Darwin has himself referred to this conversation with Henslow in his autobiography[64].) Except in a few cases, this was the attitude maintained by all the old geologists who were Lyell's contemporaries. Even as late as 1895 we find the amiable Prestwich protesting strongly against 'the _Fetish_ of uniformity[65],' and I well remember about the same time being solemnly warned by a geologist of the old school against 'poor old Lyell's fads.' It was not, indeed, till a new generation of geologists had arisen, including Godwin-Austen, Edward Forbes, Ramsay, Jukes, Darwin, Hooker and Huxley, that the real value and importance of Lyell's teaching came to be recognised and acknowledged. The most important influence of Lyell's great work is seen, however, in the undoubted fact that it inspired the men, who became the leaders in the revolution of thought which took place a quarter of a century later in respect to the organic world. Were I to assert that if the _Principles of Geology_ had not been written, we should never have had the _Origin of Species_, I think I should not be going too far: at all events, I can safely assert, from several conversations I had with Darwin, that he would have most unhesitatingly agreed in that opinion.
