Instinct in birds; nest-building.
Inheritance of acquired characters.
Sends CD a copy of a book he has had printed mainly for the interest of his children and grandchildren [later published as Recollections of past life (1872)].
In addition to the drawing of a caterpillar which CD intends to use,
HWB sends information on differences of colour and pattern between the sexes of species of Papilio.
Argynnis diana and A. sagana have females that are brightly coloured, but these may be cases of protective mimicry.
Gives the evidence on which he relied for his view, which CD thinks is erroneous, of proportion of sexes in Lepidoptera.
