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.
Seeks advice on expense of preparing plates [for Flora Antarctica].
Advice to JDH on problems of printing and publishing.
Remarks on differences of species between islets of Galapagos group.
[With the notation "If not there to be forwarded by favour of Prof. Liebig" on the address.] "I am very glad to hear that you are going to edit a German Geological Journal".
Asks JDH to forward publishing information to J. E. Gray.
Has received JDH’s infusorial specimens for Ehrenberg.
Gives information on the climate around the Falkland Islands and directs Wood to write to Captain Sulivan.
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.

Has been appointed Curator of the Herbarium at Trinity College, and his friend Dr. G. J. Allman professor. Is very pleased, and the use of library and society makes up for the loss in salary compared with the Cape. JH's testimonial had great weight with the authorities.
Outlines his domestic history. If JH knows of a suitable position vacant that may suit RH he would be pleased to hear of it. Cannot understand JH's lack of success with the photographic process RH uses. His own book is printed and is waiting for an engraving. Will send him a copy.
Has not received Tables A and B of the endowment tables. Comments on the use of these tables and would welcome his views on a possible alteration in policy.
