He makes me say that the dorsal vertebrae vary; this is simply false: I nowhere say a word about dorsal vertebrae--page 522. What an illiberal sentence that is about my pretension to candour, and about my rushing through barriers which stopped Cuvier: such an argument would stop any progress in science--page 525. How disingenuous to quote from my remark to you about my BRIEF letter [published in the 'Linn. Soc. Journal'], as if it applied to the whole subject--page 530. How disingenuous to say that we are called on to accept the theory, from the imperfection of the geological record, when I over and over again [say] how grave a difficulty the imperfection offers--page 530."] CHARLES DARWIN TO J.D. HOOKER. Down, May 30th [1860]. My dear Hooker, I return Harvey's letter, I have been very glad to see the reason why he has not read your Essay. I feared it was bigotry, and I am glad to see that he goes a little way (VERY MUCH further than I supposed) with us... I was not sorry for a natural opportunity of writing to Harvey, just to show that I was not piqued at his turning me and my book into ridicule (A "serio-comic squib," read before the 'Dublin University Zoological and Botanical Association,' February 17, 1860, and privately printed. My father's presentation copy is inscribed "With the writer's REPENTANCE, October 1860."), not that I think it was a proceeding which I deserved, or worthy of him. It delights me that you are interested in watching the progress of opinion on the change of Species; I feared that you were weary of the subject; and therefore did not send A. Gray's letters. The battle rages furiously in the United States. Gray says he was preparing a speech, which would take 1 1/2 hours to deliver, and which he "fondly hoped would be a stunner." He is fighting splendidly, and there seems to have been many discussions with Agassiz and others at the meetings. Agassiz pities me much at being so deluded. As for the progress of opinion, I clearly see that it will be excessively slow, almost as slow as the change of species... I am getting wearied at the storm of hostile reviews and hardly any useful... CHARLES DARWIN TO C. LYELL. Down, Friday night [June 1st, 1860].
