Sends the Fritz Müller article from Kosmos.

Wishes to subscribe to RM’s translation of Weismann.

Has seen Scudder’s article.

A. R. Wallace’s article ["Animals and their native countries", Nineteenth Century 5 (1879): 247–59] is excellent.

Suggests he write to Ernst Krause about publication of translation of Fritz Müller’s paper. FM’s view of mutual protection is quite new to CD.

Shares RM’s misgivings about Fritz Müller’s mutually protecting mimics. Would expect bird’s response to distasteful caterpillars to be instinctive. Believes J. J. Weir or Thomas Belt may have investigated the point.

Would like to subscribe to English edition of Weismann.
