My dear Lyell, Many thanks for your long letter. I am sorry to hear that you are in despair about your book (The 2nd volume of the 10th Edition of the 'Principles.'); I well know that feeling, but am now getting out of the lower depths. I shall be very much pleased, if you can make the least use of my present book, and do not care at all whether it is published before yours. Mine will appear towards the end of November of this year; you speak of yours as not coming out till November, 1868, which I hope may be an error. There is nothing about Man in my book which can interfere with you, so I will order all the completed clean sheets to be sent (and others as soon as ready) to you, but please observe you will not care for the first volume, which is a mere record of the amount of variation; but I hope the second will be somewhat more interesting. Though I fear the whole must be dull.
I rejoice from my heart that you are going to speak out plainly about species. My book about Man, if published, will be short, and a large portion will be devoted to sexual selection, to which subject I alluded in the 'Origin' as bearing on Man...
CHARLES DARWIN TO C. LYELL.
Down, August 22 [1867].
My dear Lyell, I thank you cordially for your last two letters. The former one did me REAL good, for I had got so wearied with the subject that I could hardly bear to correct the proofs (The proofs of 'Animals and Plants,' which Lyell was then reading.), and you gave me fresh heart. I remember thinking that when you came to the Pigeon chapter you would pass it over as quite unreadable. Your last letter has interested me in very many ways, and Ihave been glad to hear about those horrid unbelieving Frenchmen. I have been particularly pleased that you have noticed Pangenesis. I do not know whether you ever had the feeling of having thought so much over a subject that you had lost all power of judging it. This is my case with Pangenesis (which is 26 or 27 years old), but I am inclined to think that if it be admitted as a probable hypothesis it will be a somewhat important step in Biology.
I cannot help still regretting that you have ever looked at the slips, for I hope to improve the whole a good deal. It is surprising to me, and delightful, that you should care in the least about the plants. Altogether you have given me one of the best cordials I ever had in my life, and Iheartily thank you. I despatched this morning the French edition. (Of the 'Origin.' It appears that my father was sending a copy of the French edition to Sir Charles. The introduction was by Mdlle. Royer, who translated the book.) The introduction was a complete surprise to me, and I dare say has injured the book in France; nevertheless...it shows, Ithink, that the woman is uncommonly clever. Once again many thanks for the renewed courage with which I shall attack the horrid proof-sheets.
Yours affectionately, CHARLES DARWIN.
P.S.--A Russian who is translating my new book into Russian has been here, and says you are immensely read in Russia, and many editions--how many Iforget. Six editions of Buckle and four editions of the 'Origin.'
CHARLES DARWIN TO ASA GRAY.
Down, October 16 [1867].
My dear Gray, I send by this post clean sheets of Volume I. up to page 336, and there are only 411 pages in this volume. I am VERY glad to hear that you are going to review my book; but if the "Nation" (The book was reviewed by Dr. Gray in the "Nation", March 19, 1868.) is a newspaper I wish it were at the bottom of the sea, for I fear that you will thus be stopped reviewing me in a scientific journal. The first volume is all details, and you will not be able to read it; and you must remember that the chapters on plants are written for naturalists who are not botanists. The last chapter in Volume I. is, however, I think, a curious compilation of facts; it is on bud-variation. In Volume II. some of the chapters are more interesting; and Ishall be very curious to hear your verdict on the chapter on close inter-breeding. The chapter on what I call Pangenesis will be called a mad dream, and I shall be pretty well satisfied if you think it a dream worth publishing; but at the bottom of my own mind I think it contains a great truth. I finish my book with a semi-theological paragraph, in which Iquote and differ from you; what you will think of it, I know not...
CHARLES DARWIN TO J.D. HOOKER.
Down, November 17 [1867].
My dear Hooker, Congratulate me, for I have finished the last revise of the last sheet of my book. It has been an awful job: seven and a half months correcting the press: the book, from much small type, does not look big, but is really very big. I have had hard work to keep up to the mark, but during the last week only few revises came, so that I have rested and feel more myself.
Hence, after our long mutual silence, I enjoy myself by writing a note to you, for the sake of exhaling, and hearing from you. On account of the index (The index was made by Mr. W.S. Dallas; I have often heard my father express his admiration of this excellent piece of work.), I do not suppose that you will receive your copy till the middle of next month. I shall be intensely anxious to hear what you think about Pangenesis; though I can see how fearfully imperfect, even in mere conjectural conclusions, it is; yet it has been an infinite satisfaction to me somehow to connect the various large groups of facts, which I have long considered, by an intelligible thread. I shall not be at all surprised if you attack it and me with unparalleled ferocity. It will be my endeavour to do as little as possible for some time, but [I] shall soon prepare a paper or two for the Linnean Society. In a short time we shall go to London for ten days, but the time is not yet fixed. Now I have told you a deal about myself, and do let me hear a good deal about your own past and future doings. Can you pay us a visit, early in December?...I have seen no one for an age, and heard no news.
