My dear Sir

The great confusion of mind often accompanying intense blushing seems to me surprising, and I try in the enclosed MS. to throw a little light on this point.¹ But am I right in believing that the confusion, &c. is greater than the causes which induce the blushing can alone account for? I am inclined to think that this is so. If you think there is nothing strange about the degree of confusion, or if you think my suggestion false, I will strike the whole out.² Is it a recognised view with medical men (as I know nothing about the science) that there is some close sympathy between the cutaneous circulation of the face or head and the state of the brain? Is erysipelas a good instance?³ Lastly, and most important of all, if I retain the little discussion, have I given a fair abstract of your observations? I have not as yet wasted time in improving the style of the whole.

With cordial thanks | Yours very sincerely | Ch. Darwin
