DCP-LETT-3816

From:
Charles Robert Darwin
To:
Henry Walter Bates
Date:
20 Nov [1862]
Source of text:
Cleveland Health Sciences Library (Robert M. Stecher collection)
Summary:

Just finished HWB’s paper ["Contributions to an insect fauna of the Amazon valley", Trans. Linn. Soc. Lond. 23 (1862): 495–566], one of the most remarkable he has ever read. Found mimetic cases and connection of facts marvellous. Finds equally important the facts on variation and segregation of complete and semi-complete species. Questions whether insect mimicry is not due to small size and defencelessness. Criticises title of paper. Mentions that Wallace will appreciate it.
