From John Scott   [20 November – 2 December 1862]

Summary

JS does not fully accept natural selection.

Has never raised oxlips from cowslips or primroses; reports of such must be cases of crossing.

Discusses relative fertility of varieties, self-fertility of hybrids, and plans for experiments on enhanced hybrid fertility.

To H. W. Bates   20 November [1862]

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.
