Sends CD a copy of his memoir on the fenland [Geology of the fenland (1877)].

Outlines the results of his recent researches into the geological history of man, the development of Palaeolithic culture, the occurrence of Palaeolithic remains in the boulder-clays of eastern England, and their relation to glacial and inter-glacial periods.

Thanks for letter. Comments on SBJS’s research on Palaeolithic flint tools.

Thanks CD for his expression of interest in SBJS’s work. His researches on the age and divisions of the Palaeolithic period will be published soon by the Geological Survey [On the manufacture of gun-flints, the methods of excavating for flint, the age of Palaeolithic man, etc. (1879)].

Thanks CD for his gift of the Origin.
