My dear Mr Farrer

Many thanks for your notes. I do not doubt that you are right & I wrong. How I came to make such a blunder I do not know, for I examined the flowers repeatedly. I suppose I reasoned from the shape of the caudicle, & it is a fatal fault to reason whilst observing, though so necessary before hand, & so useful afterwards.

I will try to find a specimen & convict myself. I wish you or some one cd find out what insects visit the fly ophrys, & for what purpose.

I am delighted to hear that you are interested about the structure of orchids; I was formerly quite fascinated with these plants; especially with O. pyramidalis & the common Listera.

Many thanks for the facts about dogs.

Believe me | My dear Mr Farrer | yours very sincerely | Ch. Darwin
