by
others as confounded impudence. In the face of this, the tolerance and
kindness of Dr. Wallace's reply is wholly characteristic: 'I am very
much obliged to you for your letter containing so many valuable
emendations and suggestions on my "Darwinism." They will be very useful
to me in preparing another edition. Living in the country with but few
books, I have often been unable to obtain the _latest_ information, but
for the purpose of the argument the facts of a few years back are often
as good as those of to-day--which in their turn will be modified a few
years hence.... You appear to have so much knowledge of details in so
many branches of natural history, and also to have thought so much on
many of the more recondite problems, that I shall be much pleased to
receive any further remarks or corrections on any other portions of my
book.' This letter, written to a very young and quite unknown man in the
wilds of Colorado, who had merely communicated a list of more or less
trifling criticisms, can only be explained as an instance of Dr.
Wallace's eagerness to help and encourage beginners. It did not occur to
him to question the propriety of the criticisms, he did not write as a
superior to an inferior; he only saw what seemed to him a spark of
biological enthusiasm, which should by all means be kindled into flame.
Many years later, when I was at his house, he produced with the greatest
delight some letters from a young man who had gone to South America and
was getting his first glimpse of the tropical forest. What discoveries
he might make! What joy he must have on seeing the things described in
the letter, such things as Dr. Wallace himself had seen in Brazil so
long ago!"

Wallace's critical faculty was always keen and vigilant. Unlike some
critics, however, he relished genuine and well-informed criticism of his
own writings. Flattery he despised; whilst the charge of dishonesty
aroused strongest resentment. Deceived he might be, but he required
clear proof that his own eyes and ears had led him astray. Romanes, who
had propounded the forgotten theory of physiological selection, charged
Wallace with adopting it as his own. This was not only untrue, it was
ridiculous; and Wallace, after telling him so and receiving no apology,
dropped him out of his recognition. During Romanes' illness Mr.
Thiselton-Dyer wrote to Wallace and sought to bring about a
reconciliation, and Wallace replied:
