*Mr. Hopkins ('Fraser') states--I am quoting only from vague memory--that, "I argue in favour of my views from the extreme imperfection of the Geological Record," and says this is the first time in the history of Science he has ever heard of ignorance being adduced as an argument. But I repeatedly admit, in the most emphatic language which I can use, that the imperfect evidence which Geology offers in regard to transitorial forms is most strongly opposed to my views. Surely there is a wide difference in fully admitting an objection, and then in endeavouring to show that it is not so strong as it at first appears, and in Mr. Hopkins's assertion that I found my argument on the Objection. *I would also put a note to "Natural Selection," and show how variously it has been misunderstood. *A writer in the 'Edinburgh Philosophical Journal' denies my statement that the Woodpecker of La Plata never frequents trees. I observed its habits during two years, but, what is more to the purpose, Azara, whose accuracy all admit, is more emphatic than I am in regard to its never frequenting trees. Mr. A. Murray denies that it ought to be called a woodpecker; it has two toes in front and two behind, pointed tail feathers, a long pointed tongue, and the same general form of body, the same manner of flight, colouring and voice. It was classed, until recently, in the same genus--Picus--with all other woodpeckers, but now has been ranked as a distinct genus amongst the Picidae. It differs from the typical Picus only in the beak, not being quite so strong, and in the upper mandible being slightly arched. I think these facts fully justify my statement that it is "in all essential parts of its organisation" a Woodpecker.] CHARLES DARWIN TO T.H. HUXLEY. Down, November 22 [1860]. My dear Huxley, For heaven's sake don't write an anti-Darwinian article; you would do it so confoundedly well. I have sometimes amused myself with thinking how I could best pitch into myself, and I believe I could give two or three good digs; but I will see you -- first before I will try. I shall be very impatient to see the Review. (The first number of the new series of the 'Nat. Hist. Review' appeared in 1861.) If it succeeds it may really do much, very much good... I heard to-day from Murray that I must set to work at once on a new edition (The 3rd edition.) of the 'Origin.' [Murray] says the Reviews have not improved the sale. I shall always think those early reviews, almost entirely yours, did the subject an ENORMOUS service. If you have any important suggestions or criticisms to make on any part of the 'Origin,' I should, of course, be very grateful for [them]. For I mean to correct as far as I can, but not enlarge. How you must be wearied with and hate the subject, and it is God's blessing if you do not get to hate me. Adios. CHARLES DARWIN TO C. LYELL. Down, November 24th [1860]. My dear Lyell,
