I do grudge Hardwicke very much having not only the publisher's but the
author's profits. It so often happens that popular lectures designed for
a class and inspired by an attentive audience's sympathy are better than
any writing in the closet for the purpose of educating the many as
readers, and of remunerating the publisher and author. I would lose no
time in considering well what steps to take to rescue the copyright of
the third thousand.

As for the value of the work thus done in support of Darwin's theory, it
is worth while quoting the words of Lord Kelvin, when, as President of
the Royal Society in 1894, it fell to him to award Huxley the Darwin
Medal:--

To the world at large, perhaps, Mr. Huxley's share in moulding the
thesis of NATURAL SELECTION is less well-known than is his bold
unwearied exposition and defence of it after it had been made public.
And, indeed, a speculative trifler, revelling in the problems of the
"might have been," would find a congenial theme in the inquiry how soon
what we now call "Darwinism" would have met with the acceptance with
which it has met, and gained the power which it has gained, had it not
been for the brilliant advocacy with which in its early days it was
expounded to all classes of men.

That advocacy had one striking mark: while it made or strove to make
clear how deep the new view went down, and how far it reached, it never
shrank from trying to make equally clear the limit beyond which it could
not go.]
