you seemed to think this important, it might be worth your reading; though I do not feel sure that you will come to the same probable conclusion that I have done. By the way, the Bishop makes a very telling case against me, by accumulating several instances where I speak very doubtfully; but this is very unfair, as in such cases as this of the dog, the evidence is and must be very doubtful... CHARLES DARWIN TO ASA GRAY. Down, August 11 [1860]. My dear Gray, On my return home from Sussex about a week ago, I found several articles sent by you. The first article, from the 'Atlantic Monthly,' I am very glad to possess. By the way, the editor of the "Athenaeum" (August 4, 1860.) has inserted your answer to Agassiz, Bowen, and Co., and when I therein read them, I admired them even more than at first. They really seemed to be admirable in their condensation, force, clearness and novelty. I am surprised that Agassiz did not succeed in writing something better. How absurd that logical quibble--"if species do not exist, how can they vary?" As if any one doubted their temporary existence. How coolly he assumes that there is some clearly defined distinction between individual differences and varieties. It is no wonder that a man who calls identical forms, when found in two countries, distinct species, cannot find variation in nature. Again, how unreasonable to suppose that domestic varieties selected by man for his own fancy should resemble natural varieties or species. The whole article seems to me poor; it seems to me hardly worth a detailed answer (even if I could do it, and I much doubt whether I possess your skill in picking out salient points and driving a nail into them), and indeed you have already answered several points. Agassiz's name, no doubt, is a heavy weight against us...
