My dear Sir
I am very much obliged for the beautiful photograph.1 There is certainly a marked difference between the two sides of the face, but the only difference in expression that I can recognise, is that one side looks a little less devout. As you have attended so closely to differences on the sides of the face, shall I not return the photo— If so send me a post card.2 I read a few days ago with extraordinary interest your remarkable article on Inhibition.3 How wonderfully complex the nervous system is! I arrived at one side-conclusion, viz that you, & not I, ought to have written my book on Expression.
My dear Sir | yours very sincerely | Ch. Darwin
