PALEONTOLOGY 103 



waste of time to try to tell what the nine thousand 

 nine hundred and ninety-nine were from the form of 

 one which is like neither of them. And even when 

 we add to this our knowledge of living species it will 

 constitute a very fragmentary history of the animal 

 kingdom from its beginning to the pi-esent time. 



With a record so extremely fragmentary it seems 

 marvelous that the evolutionist persists in writing a 

 definite history of the whole animal kingdom by sand- 

 wiching between the few known species an infinite 

 number of assumed unknown forms, that he may com- 

 plete his imaginary tree of life.
