384 THE BIOCOSMOS PARTICULARIZED. 



animal with which science concerns itself in 

 one way or other. 



Then there is the separation of Earth-life 

 into its two lines of development, vegetal and 

 animal, so that every region of Earth has its 

 double life known as Flora and Fauna. More- 

 over Earth-life has its peculiar circulation; 

 there is a continual movement of these vegetal 

 and animal forms called their geographic 

 distribution over the terrestrial surface, and 

 this movement is traceable through the past 

 geologic ages. 



Equally certain is the final separation, in 

 which Life separates from its separated in- 

 dividualized condition. It is the logic of Life 

 as particular that it ends in death, for it is 

 not universal. Each living individual as 

 Plant or Animal goes its round of birth, ma- 

 turity, cessation, when it returns its elements 

 to the Earth-life. It may propagate itself and 

 thus show its persistent or immortal portion ; 

 but as mere individual it is mortal. 



3. Life to Unlife. There is the return of all 

 living things to their inorganic constituents, 

 which thus are ready for a new vitalization. 

 Such is the round of Earth-life, which inces- 

 santly ejects into its Unlife vast masses of 

 its Life, a kind of general excretion of the 

 huge terrestrial individual, which therein re- 

 sembles the small organisms of Plant and Ani-
