  and 
  

   something 
  else

  The 
  writer 
  wonld 
  compare 
  the 
  divisions 
  of 
  geologic 
  

   history 
  in 
  their 
  relations 
  to 
  the 
  geologic 
  history 
  of 
  the 
  

   continents 
  to 
  the 
  divisions 
  which 
  have 
  been 
  made 
  in 
  the 
  

   history 
  of 
  man. 
  The 
  great 
  divisions 
  of 
  American 
  and 
  

   European 
  history 
  have 
  been 
  based 
  on 
  great 
  events 
  in 
  the 
  

   history 
  of 
  these 
  peoples, 
  and 
  ultimately 
  these 
  high 
  points 
  

   may 
  become 
  the 
  basis 
  for 
  the 
  division 
  of 
  the 
  histories 
  of 
  

   all 
  peoples, 
  the 
  histories 
  of 
  other 
  peoples 
  being 
  made 
  to 
  

   conform 
  to 
  that 
  of 
  Europeans 
  and 
  Americans. 
  In 
  Chi- 
  

   nese 
  history, 
  for 
  instance, 
  the 
  high 
  points 
  would 
  be 
  at 
  

   times 
  which 
  might 
  coincide 
  in 
  some 
  instances 
  with 
  the 
  

   high 
  points 
  in 
  our 
  history 
  and 
  in 
  others 
  not. 
  It 
  may 
  

   come 
  to 
  pass 
  that 
  ultimately 
  another 
  civilization 
  with 
  

   different 
  antecedents 
  will 
  supplant 
  the 
  existing 
  one. 
  In 
  

   this 
  civilization, 
  the 
  high 
  points 
  in 
  the 
  present 
  one 
  may 
  

   have 
  no 
  significance. 
  So 
  the 
  high 
  points 
  in 
  European 
  

   geologic 
  history 
  may 
  or 
  may 
  not 
  have 
  any 
  relation 
  to 
  the 
  

   high 
  points 
  of 
  American 
  geologic 
  history. 
  In 
  lands 
  

   other 
  than 
  those 
  in 
  which 
  the 
  periods 
  were 
  first 
  defined, 
  

   fossils 
  would 
  be 
  the 
  final 
  arbiters 
  of 
  period 
  delimitation.
