My dear M^r. Woolner

I dare say you often meet and know well painters. Could you persuade some trustworthy men to observe young and inexperienced girls who serve as models, and who at first blush much, how low down the body the blush extends. Several eminent surgeons have been observing for me, and with a single exception have never seen a blush extend beneath (and rarely so far down) as the upper $\frac{2}{3}$ of the breasts.²

Moreau says a celebrated French painter once saw a new model blushing all over her body.³ So that I want much to hear what the experience is of cautious and careful English artists: I always distrust memory. Can you aid me?

The tips to the ears have become quite celebrated. One Reviewer (Nature) says they ought to be called, as I suggested in joke, Angulus Woolnerianus.⁴

A great German physiologist is very proud to find that he has tips well developed & I believe will send me a photograph of his ears; & if a good case, I think I would have it photographed on wood engraved for new Edit.⁵ Making of course no change in my text.

Yours very sincerely, | Ch. Darwin
