 through the deterioration of the climate, it will disappear and the 

 last men will live like Eskimos on the entirely glaciated earth. The 

 radiation from the sun being stable, the intellectual and physical 

 evolution of humanity will be able for an immeasurable time to 

 mount to heights surpassing, perhaps, anything the imagination is 

 capable of conceiving. 



Thus, as a result of the development of the differential theories, 

 a new and unsought contribution to cosmology of high and moral 

 value has been obtained.
