Dear Sir
I am much obliged for your kind and courteous letter. From what I have observed in various periodicals I can see that the discussion of the Philosophy of Evolution is at present very important. In the course of a few days I will read what you have been so kind as to point out to me with reference to instinct.1
I remain, with much respect | Yours faithfully | Charles Darwin.
