Down. | Bromley. | Kent. S.E..

Feb. 25th

My dear Sir

It was my slip of the pen; & I remember that I had just before writing been reading about Ephemera.—

I am particularly obliged for the facts about the hybrids; I had been considering Walsh (& Bates (?)) view that these organs played an important part in keeping incipient species distinct, & I felt so little satisfied that I had just resolved not to notice this view; & now you have given me solid grounds for rejecting it:— Many thanks.—

For the chance of your liking to have a copy of my book on ``Variation under Domestication'', I have told Mr. Murray to send you a copy of the new Edit. or rather Reprint, which will be out in a few days.—

My dear Sir | Yours sincerely | Ch. Darwin
