Will forward ARW’s "admirable" paper to Linnean Society ["On the zoological geography of the Malay Archipelago", J. Linn. Soc. Lond. (Zool.) 4 (1860): 172–84].

Discusses geographical distribution of animals in the Malay Archipelago; relation of distribution to depth of sea between islands.

Relation of Celebes to Africa almost passes belief.

Differs wholly from ARW on colonisation of oceanic islands; does not believe in Forbes’s great continental extensions.

Anticipates Owen’s opposition to their views, but "he is a poor reasoner & deeply considers the good opinion of the world, especially the aristocratic world".
