My dear Sir

Forgive me for troubling you with one line. Since writing my P.S. I have read the part on the influence of the nervous system on the nutrition of parts in your last Edit. of Paget’s Lectures.—2 I had not read before the part in this Edit. & I see how foolish I was.— But still I shd. be extremely grateful for any hint or evidence of the influence of mental attention on the capillary or local circulation of the skin or of any part, to which the mind may be intently & long directed. For instance if thinking intently about a local eruption on the skin (not on the face for shame might possibly intervene) caused it temporarily to redden—or thinking of a tumour caused it to throb, independently of increased heart-action.—

I beg you to excuse me | Yours very sincerely | Ch. Darwin
