My dear Wallace
The addresses which you have sent me are capital, especially that to the Rajah;
& I have despatched two sets of queries. I now enclose a copy to you &
I fully admit the probability of ``protective adaptation'' having come into play with female butterflies as well as with female birds. I have a good many facts which make me believe in sexual selection as applied to man, but whether I shall convince any one else is very doubtful.
Dear Wallace | yours very sincerely | Ch. Darwin
