  the 
  Cambric 
  and 
  Ordovicic 
  of 
  former 
  classifications. 
  Whether 
  the 
  

   Ozarkic 
  is 
  ultimately 
  given 
  the 
  rank 
  of 
  a 
  system 
  or 
  is 
  regarded 
  

   simply 
  as 
  a 
  series 
  forming 
  the 
  uppermost 
  division 
  of 
  the 
  Cambric, 
  

   does 
  not 
  concern 
  us 
  here 
  ; 
  but 
  rather 
  the 
  fact 
  that 
  the 
  above-listed 
  

   formations 
  are 
  of 
  Ozarkic 
  age.
