Thanks for information on Malden Island. Comments on its plants and their relationship to the Galapagos flora. Discusses the flora of Oceania. Gives his opinion on the extent of the uniformity in species and forms amongst South Sea Islands. Large genera are more widely diffused and have a larger proportion of species with wide ranges.

Writes to correct a statement made in his 1837 paper "On the formation of mould" [Collected papers 1: 49–53]. He should have said that marl was put on the field 30 years ago, not 80. Observations made on a visit to the field showed that worms had undermined the marl spread on the field at a faster rate than previously reported.

Thanks for JDH’s interesting details about the Galapagos.

Clarification of CD’s query about the relationship between the range of a genus and the ranges of its constituent species.
