AND ITS SELF-CONSEKVATION. 281 



process of coming into existence of any given type 

 should be something which has occurred but once in 

 an infinitely extended duration. On the contrary, 

 such origination must occur whenever as well as wher- 

 ever the conditions favorable to such process become 

 focused into reality. In fact, as already intimated, just 

 this focusing of "favorable conditions" is itself the 

 process of the origination of the units constituting the 

 type. And, as the argument of the present volume 

 goes to show, the order here, though necessarily chrono- 

 logical locally, is and can be only logical for the Universe 

 as a whole, seeing that in the Universe as a whole every 

 phase of existence possible to a rational world must be 

 perpetual. That is, in the Universe as a whole the 

 "moment" of creation for each type must be eternal, 

 just as the "center" of creation for each type must be 

 co-extensive with space. 



Such is the second suggestion jn its universal and 

 more abstract form. The special application it is in- 

 tended to lead up (or down) to is: That the same phase 

 of organic differentiation must have occurred simultan- 

 eously over more or less widely extended areas, as also 

 (and especially in case of land animals) over more or 

 less widely separated areas of the earth the type in 

 any given case remaining essentially the same throughout 

 the given area or areas so long as the environment 

 remained substantially the same over such area or 

 areas. 



Whether in the history of the earth such coincidence 

 of environment actually existed over areas widely separ- 

 ated from each other, is of course a question to be decided 

 upon geological evidence. And such evidence is not
