CD cannot swallow continental extensions. Has written to Lyell giving a lengthy criticism of the concept [see 1910] and has asked Lyell to forward the letter to JDH.

Troubled by JDH’s connection between Antarctic island flora and Fuegia, which CD sees as part of a general relation to southern circumpolar flora. Encloses list [not found] of plants from Tristan d’Acunha.
