Dear Sir, As I have never studied the science of language, it may perhaps seem presumptuous, but I cannot resist the pleasure of telling you what interest and pleasure I have derived from hearing read aloud your volume ('Chapters on Language,' 1865.)I formerly read Max Muller, and thought his theory (if it deserves to be called so) both obscure and weak; and now, after hearing what you say, Ifeel sure that this is the case, and that your cause will ultimately triumph. My indirect interest in your book has been increased from Mr. Hensleigh Wedgwood, whom you often quote, being my brother-in-law.
No one could dissent from my views on the modification of species with more courtesy than you do. But from the tenor of your mind I feel an entire and comfortable conviction (and which cannot possibly be disturbed) that if your studies led you to attend much to general questions in natural history you would come to the same conclusion that I have done.
Have you ever read Huxley's little book of Lectures? I would gladly send a copy if you think you would read it.
Considering what Geology teaches us, the argument from the supposed immutability of specific types seems to me much the same as if, in a nation which had no old writings, some wise old savage was to say that his language had never changed; but my metaphor is too long to fill up.
Pray believe me, dear Sir, yours very sincerely obliged, C. DARWIN.
1866.
[The year 1866 is given in my father's Diary in the following words:--"Continued correcting chapters of 'Domestic Animals.'
March 1st.--Began on 4th edition of 'Origin' of 1250 copies (received for it 238 pounds), ****** 7500 copies altogether.
May 10th.--Finished 'Origin,' except revises, and began going over Chapter XIII. of 'Domestic Animals.'
November 21st.--Finished 'Pangenesis.'
December 21st.--Finished re-going over all chapters, and sent them to printers.
December 22nd.--Began concluding chapter of book."He was in London on two occasions for a week at a time, staying with his brother, and for a few days (May 29th-June 2nd) in Surrey; for the rest of the year he was at Down.
There seems to have been a gradual mending in his health; thus he wrote to Mr. Wallace (January 1866):--"My health is so far improved that I am able to work one or two hours a day."With respect to the 4th edition he wrote to Sir J.D. Hooker:--"The new edition of the 'Origin' has caused me two great vexations. Iforgot Bates's paper on variation (This appears to refer to "Notes on South American Butterflies," Trans. Entomolog. Soc., vol. v. (N.S.).), but Iremembered in time his mimetic work, and now, strange to say, I find I have forgotten your Arctic paper! I know how it arose; I indexed for my bigger work, and never expected that a new edition of the 'Origin' would be wanted.
"I cannot say how all this has vexed me. Everything which I have read during the last four years I find is quite washy in my mind." As far as Iknow, Mr. Bates's paper was not mentioned in the later editions of the 'Origin,' for what reason I cannot say.
In connection with his work on 'The Variation of Animals and Plants,' Igive here extracts from three letters addressed to Mr. Huxley, which are of interest as giving some idea of the development of the theory of 'Pangenesis,' ultimately published in 1868 in the book in question:]
CHARLES DARWIN TO T.H. HUXLEY.
Down, May 27, [1865?].
...I write now to ask a favour of you, a very great favour from one so hard worked as you are. It is to read thirty pages of MS., excellently copied out and give me, not lengthened criticism, but your opinion whether I may venture to publish it. You may keep the MS. for a month or two. I would not ask this favour, but I REALLY know no one else whose judgment on the subject would be final with me.
The case stands thus: in my next book I shall publish long chapters on bud- and seminal-variation, on inheritance, reversion, effects of use and disuse, etc. I have also for many years speculated on the different forms of reproduction. Hence it has come to be a passion with me to try to connect all such facts by some sort of hypothesis. The MS. which I wish to send you gives such a hypothesis; it is a very rash and crude hypothesis, yet it has been a considerable relief to my mind, and I can hang on it a good many groups of facts. I well know that a mere hypothesis, and this is nothing more, is of little value; but it is very useful to me as serving as a kind of summary for certain chapters. Now I earnestly wish for your verdict given briefly as, "Burn it"--or, which is the most favourable verdict I can hope for, "It does rudely connect together certain facts, and I do not think it will immediately pass out of my mind." If you can say this much, and you do not think it absolutely ridiculous, I shall publish it in my concluding chapter. Now will you grant me this favour? You must refuse if you are too much overworked.
I must say for myself that I am a hero to expose my hypothesis to the fiery ordeal of your criticism.
July 12, [1865?].
My dear Huxley, I thank you most sincerely for having so carefully considered my MS. It has been a real act of kindness. It would have annoyed me extremely to have re-published Buffon's views, which I did not know of, but I will get the book; and if I have strength I will also read Bonnet. I do not doubt your judgment is perfectly just, and I will try to persuade myself not to publish. The whole affair is much too speculative; yet I think some such view will have to be adopted, when I call to mind such facts as the inherited effects of use and disuse, etc. But I will try to be cautious...
