As to the terminology used in the above 

 table the termination " ian " is used to 

 indicate an epoch or stage in the process of 

 evolution much as the same termination is 

 used in geological evolution for the termination 

 of a primary division of strata as in the words 

 " Devonian " and " Silurian." As the pro- 

 cesses are here simultaneous in different 

 worlds, instead of chronological in order in 

 one world, temperature takes the place of 

 time, but the same effects would happen 

 chronologically could the process be observed 

 in the same sun over a period of millions
