What a lot of interesting things have been lately published. I liked extremely your review of De Candolle. What an awfully severe article that by Falconer on Lyell ("Athenaeum", April 4, 1863, page 459. The writer asserts that justice has not been done either to himself or Mr. Prestwich--that Lyell has not made it clear that it was their original work which supplied certain material for the 'Antiquity of Man.' Falconer attempts to draw an unjust distinction between a "philosopher" (here used as a polite word for compiler) like Sir Charles Lyell, and original observers, presumably such as himself, and Mr. Prestwich. Lyell's reply was published in the "Athenaeum", April 18, 1863. It ought to be mentioned that a letter from Mr. Prestwich ("Athenaeum", page 555), which formed part of the controversy, though of the nature of a reclamation, was written in a very different spirit and tone from Dr. Falconer's.); I am very sorry for it; Ithink Falconer on his side does not do justice to old Perthes and Schmerling...I shall be very curious to see how he [Lyell] answers it to-morrow. (I have been compelled to take in the "Athenaeum" for a while.) Iam very sorry that Falconer should have written so spitefully, even if there is some truth in his accusations; I was rather disappointed in Carpenter's letter, no one could have given a better answer, but the chief object of his letter seems to me to be to show that though he has touched pitch he is not defiled. No one would suppose he went so far as to believe all birds came from one progenitor. I have written a letter to the "Athenaeum" ("Athenaeum", 1863, page 554: "The view given by me on the origin or derivation of species, whatever its weaknesses may be, connects (as has been candidly admitted by some of its opponents, such as Pictet, Bronn, etc.), by an intelligible thread of reasoning, a multitude of facts: such as the formation of domestic races by man's selection,--the classification and affinities of all organic beings,--the innumerable gradations in structure and instincts,--the similarity of pattern in the hand, wing, or paddle of animals of the same great class,--the existence of organs become rudimentary by disuse,--the similarity of an embryonic reptile, bird, and mammal, with the retention of traces of an apparatus fitted for aquatic respiration; the retention in the young calf of incisor teeth in the upper jaw, etc.--the distribution of animals and plants, and their mutual affinities within the same region,--their general geological succession, and the close relationship of the fossils in closely consecutive formations and within the same country; extinct marsupials having preceded living marsupials in Australia, and armadillo-like animals having preceded and generated armadilloes in South America,--and many other phenomena, such as the gradual extinction of old forms and their gradual replacement by new forms better fitted for their new conditions in the struggle for life. When the advocate of Heterogeny can thus connect large classes of facts, and not until then, he will have respectful and patient listeners.") (the first and last time I shall take such a step) to say, under the cloak of attacking Heterogeny, a word in my own defence. My letter is to appear next week, so the Editor says; and I mean to quote Lyell's sentence (See the next letter.) in his second edition, on the principle if one puffs oneself, one had better puff handsomely...

CHARLES DARWIN TO C. LYELL.

Down, April 18 [1863].

My dear Lyell, I was really quite sorry that you had sent me a second copy (The second edition of the 'Antiquity of Man' was published a few months after the first had appeared.) of your valuable book. But after a few hours my sorrow vanished for this reason: I have written a letter to the "Athenaeum", in order, under the cloak of attacking the monstrous article on Heterogeny, to say a word for myself in answer to Carpenter, and now Ihave inserted a few sentences in allusion to your analogous objection (Lyell objected that the mammalia (e.g. bats and seals) which alone have been able to reach oceanic islands ought to have become modified into various terrestrial forms fitted to fill various places in their new home.
