Transcription

Down, Bromley, Kent. S.E.

Oct. 17. 1868.

My dear Sir

All the various pieces of information which you have so very kindly sent me will be of use. By an odd chance I was wishing only yesterday to know with some precision the nature of the changes in the plumage of male pheasants. Your case of the female of Porphyrio is still more interesting, as I have been carefully collecting all instances of the females being in any way more ornamented; and when next in London I must find out from Mr. Bartlett whether anything is know of the incubation of this species.

I assure you I thoroughly enjoyed your visit here, and reaped much profit from the conversation of you three gentlemen.

I am still at work on sexual selection in regard to birds, for it has turned out a frightfully large subject.

With many thanks believe me | yours very sincerely | Charles Darwin.
