Thus in my paper on Man[41] I aim solely at showing that brutes
are modified in a _great variety_ of ways by Natural Selection, but that
in _none of these particular_ ways can man be modified, because of the
superiority of his intellect. I therefore no doubt overlook a few
smaller points in which Natural Selection may still act on men and
brutes alike. Colour is one of them, and I have alluded to this in
correlation to constitution in an abstract I have made at Sclater's
request for the _Natural History Review_.[42] At the same time, there is
so much evidence of migrations and displacements of races of man, and so
many cases of peoples of distinct physical characters inhabiting the
same or similar regions, and also of races of uniform physical
characters inhabiting widely dissimilar regions, that the external
characteristics of the chief races of man must I think be older than his
present geographical distribution, and the modifications produced by
correlation to favourable variations of constitution be only a secondary
cause of external modification.
I hope you may get the returns from the Army.
