■which are grouped 323 feet over the present rivercourse, are first de- 

 scribed and considered, even in these extreme cases, as suggestive of 

 river-action. From these the author turns to others at Kongshavn, near 

 Christiania, entirely dissociated from any considerable waterflow. The 

 theory is accepted by which the original water-power is sought during 

 the prevalence of an ice-sheet, subject to temporary meltings, a theory 

 supported by the travelled nature of the contents of the kettles. Their 

 site, however, was under water at the decline of the ice-period. H. M.

A summary of the recent views on Cosmogony. The author upholds 



the view that the Glacial epoch was caused by a decrease in the heat of
