The Influence of Geology on Population [written to show that geology 

 has had some share in deciding the areas to be occupied by the various, 

 settlers in Britain ; thus comparisons are drawn between the geology of 

 Denmark and that of the part of England where the Danes settled ; also 

 between the rocky and deeply-indented coast of Norway and that of the west 

 coast of Scotland ; further refers to the fact that the geology of Wales and 

 Cornwall by its mountainous character preserved the Celtic race in England 

 from extinction]. Sci. Goss., Aug. 1S88, pp. 177-179.
