From George Robert Waterhouse [April 1844]
Summary
Regularly attends Owen’s lectures. Owen at pains to show groups are not linked. Thus makes Lepidosiren appear fish-like.
GRW thinks embryology will become chief guide to insect classification. But contradictions between classification based on embryological and adult characters do occur.

Summary
Thanks for information on Malden Island. Comments on its plants and their relationship to the Galapagos flora. Discusses the flora of Oceania.

From G. R. Waterhouse [after 26 April 1844]

Letter no: | DCP-LETT-774 |
From J. D. Hooker 28 October 1844
Summary
Discusses the connection between climate and vegetation. Believes that an equable climate is unfavourable to increase of species either by importation or modification of existing forms; illustrates his view with reference to particular floras. Hopes to acquire facts to support CD’s idea that isolation is important in producing new forms. Considers the floras of islands some of which do have distinctive species but others of which do not. Agrees that the wide ranges of cryptogams are a consequence of their means of dispersal. Asks for references to works on original creation and species mutability in order to get the best notions of "the (mad) theories of some men from Lamarck’s twaddle upwards".
