My dear Hooker
Thank you for telling me about obscurity of style. But on my life no nigger with [a] lash over him could have worked harder at clearness than I have. But the very difficulty to me, by itself leads to [the] probability that I fail. Yet one lady who has read all my M.S. has found only 2 or 3 obscure sentence[s].1 But Mrs Hooker2 having so found it, makes me tremble.— I will do [2] my best in proofs. You are a good man to take trouble to write about it—
With respect to our mutual muddle, I never for a moment thought we could not make our ideas clear to each other by talk or if either of us had time to write in extenso.
I imagine from some expressions (but if you asked me what, I could not answer) [3] that you look at variability as some necessary contingency with organisms, & further that there is some necessary tendency in the variability to go on diverging in character or degree. If you do, I do not agree. "Reversion" again, (a a form of inheritance) I look at as [in] no way directly connected with variation, though of course inheritance is of fundamental importance to us, for if a variation be not inherited, it is of [4] no signification to us.— It was on such points as these I fancied that we perhaps started differently.—
I fear that my Book will not deserve at all the pleasant things you say about it & good Lord how I do long to have done with it:—____________________________________________________________
Since the above was written I have received & been much interested by A[sa]. Gray3.
[5]I am delighted at his note about my & Wallace’s paper4: He will go round, for it is futile to give up very many species, & stop at an arbitrary line at others. It is what my grandfather called Unitarianism, "a feather-bed to catch a falling Christian".5 —
The geology at p. 447 seems to be inextricable confusion.6
Some time ago A[sa]. Gray [6] wrote to me for my notions on recent migration during late periods, & I gave him the passage before Glacial period by the almost continuous circumpolar land.— I presume he alludes to this, not [one illeg. word struck through] correctly, by putting me before E[dward] Forbes7[,] Hooker8 & De Candolle9. —
But he has changed my doctrine, apparently [7] after consulting Dana10.— I knew there was some slight evidence from range of the shell Gnathodon in U. States of warmer climate since Glacial epoch; but I do not believe there is any such evidence for Europe.—
I once consulted Lyell11 on this point & he seemed to know little & be very doubtful about this warmer period since Glacial.12
I doubt whether Megatherium & Co. have really been found together with the northern Elephant; nor do I at all admit that [8] Megatherium, Mylodon & Co are by themselves proof of warmer climate. The argument from the woolly Elephant & woolly Rhinoceros I look at as false. If my letter did start these speculations, I am sorry I ever wrote it, for in my opinion they botch the subject.—
