probably the first
occasion on which he realised the extent of this great and striking
divergence in opinion between himself and his colleague.

He had, however, some indication of it in Wallace's paper on Man,
"Anthropological Review," 1864. (See Letter 406). He wrote to Lyell,
May 4th, 1869, "I was dreadfully disappointed about Man; it seems to me
incredibly strange." And to Mr. Wallace, April 14th, 1869, "If you had
not told me, I should have thought that [your remarks on Man] had been
added by some one else. As you expected, I differ grievously from you,
and I am very sorry for it."

LETTER 409. TO T.H. HUXLEY. Down, Thursday, February 21st [1868-70?].

I received the Jermyn Street programme, but have hardly yet considered
it, for I was all day on the sofa on Tuesday and Wednesday. Bad though
I was, I thought with constant pleasure of your very great kindness in
offering to read the proofs of my essay on man. I do not know whether
I said anything which might have appeared like a hint, but I assure you
that such a thought had never even momentarily passed through my mind.
Your offer has just made all the difference, that I can now write,
whether or no my essay is ever printed, with a feeling of satisfaction
instead of vague dread.

Beg my colleague, Mrs. Huxley, not to forget the corrugator supercilii:
it will not be easy to catch the exact moment when the child is on the
point of crying, and is struggling against the wrinkling up [of] its
little eyes; for then I should expect the corrugator, from being little
under the command of the will, would come into play in checking or
stopping the wrinkling. An explosion of tears would tell nothing.

LETTER 410. TO FRANCIS GALTON. Down, December 23rd [1870?].

I have only read about fifty pages of your book (to the Judges) (410/1.
"Hereditary Genius: an Inquiry into its Laws and Consequences," by
Francis Galton, London, 1869. "The Judges of England between 1660 and
1865" is the heading of a section of this work (page 55). See "Descent
of Man" (1901), page 41.), but I must exhale myself, else something
will go wrong in my inside. I do not think I ever in all my life read
anything more interesting and original. And how well and clearly you
put every point! George, who has finished the book, and who expressed
himself just in the same terms, tells me the earlier chapters are
nothing in interest to the later ones! It will take me some time to get
to these later chapters,
