Summary:
CD will pay for the American trip if it takes place.
Asks whether FD can help him understand the eyes of cephalopods; is the structure the same as in the Vertebrata and are the parts developed from homologous layers of skin?
Has been pleased by a recent review.
Postscript: Is thinking of a cheap edition of the Origin [1872] in which he hopes to answer St George Mivart’s criticisms.
Asks FD whether he can get some references to good papers on cephalapod eyes.
