Summary:
Thanks WDF for information on blackbirds’ nests [see Natural selection, p. 505].
Problem of choosing from among the load of curious facts for chapter on "Instinct" [Natural selection, ch. 10; Origin, ch. 7] perplexes him.
Asks about behaviour of chicks in danger and whether crossed animals are wilder than either parent.
