From A. R. Wallace 8 [April] 1868
Summary
If CD is not convinced by his notes on sterility, ARW has little doubt that he is wrong. In fact he was only half-convinced by his own arguments.
Modifies his first proposition [a species varies occasionally in two directions, but owing to free inter-crossing the variations never increase] and further discusses the subject.
Encloses Berthold Seemann’s notes on flora of the Hawaiian Islands. Presence of European alpine species in Hawaiian volcanoes is a "hard nut" for geographical distribution [but see ARW’s Island life (1880), p. 323].

From George Robert Crotch 2 October [1868]
Summary
Bibliographical references on [stridulation in] Coleoptera. Finds no idea of sex has occurred to authors [i.e., they do not find the stridulating organs differing according to sex; cf. Descent 1: 378–85].

From A. R. Wallace 24 March [1868]
Summary
Returns George Darwin’s criticisms of his notes on sterility and sends further notes in reply. Since there are degrees of sterility between varieties, "is it not probable that natural selection can accumulate these variations?" Varieties that are adapted to new conditions could then survive and form new species without being isolated.
