Origin of Antarctic brash ice. Further on case of Lycopodium: does Hooker know any genera of plants whose species are variable in one continent but not in another? Discussion on variations between floras as regards species richness, and factors affecting geographical distribution. On species, Darwin expects "that I shall be able to show even to sound naturalists that there are two sides to the question of the immutability of species; – that facts can be viewed and grouped under the notion of allied species having descended from common stocks". Mentions books and papers for and against species mutability. Darwin believes past absurd ideas arose from no one's having approached subject on side of variation under domestication. Would like to see Clarke's paper and would welcome visit from Hooker.
