To Ernst Haeckel [after 10] August – 8 October [1864]
Summary
Can understand EH’s feelings on death of his wife.
CD was impressed by manner in which species in South America are replaced by closely allied ones, by affinity of species inhabiting islands near S.

Asks EH to thank Carl Gegenbaur [for Vergleichende Anatomie der Wirbelthiere (1864)].
