  The 
  

   author 
  still 
  holds 
  the 
  view 
  that 
  the 
  Berea 
  grit 
  is 
  the 
  real 
  floor 
  of 
  

   the 
  Carboniferous 
  series 
  — 
  u 
  not 
  necessarily 
  the 
  base 
  of 
  the 
  Car- 
  

   boniferous, 
  but 
  the 
  most 
  convenient 
  base 
  line 
  for 
  the 
  Waverly," 
  

   remarking 
  that 
  a 
  study 
  of 
  localities 
  " 
  and 
  collections 
  on 
  which 
  

   Dr. 
  Newberry's 
  opinion 
  [that 
  the 
  Bedford 
  shale 
  fossils 
  are 
  Car- 
  

   boniferous] 
  was 
  founded 
  has 
  convinced 
  the 
  writer 
  that 
  these 
  

   species 
  do 
  not 
  occur 
  in 
  the 
  typical 
  Bedford, 
  but 
  in 
  thin 
  flags 
  

   associated 
  or 
  inter 
  bedded, 
  while 
  the 
  typical 
  Bedford, 
  especially 
  

   in 
  central 
  Ohio, 
  where 
  it 
  reposes 
  directly 
  upon 
  the 
  l 
  Black 
  shale,* 
  

   carries 
  a 
  considerable 
  series 
  of 
  fossils 
  forming 
  a 
  decidedly 
  Devo- 
  

   nian 
  assemblage."

  In 
  a 
  critical 
  case 
  like 
  this, 
  it 
  is 
  

   unfortunate 
  that 
  so 
  keen 
  an 
  observer 
  as 
  Professor 
  Herrick 
  should 
  

   describe 
  as 
  " 
  typical 
  Bedford 
  " 
  a 
  formation 
  which 
  confessedly 
  

   does 
  not 
  contain 
  the 
  typical 
  fossils 
  of 
  the 
  Bedford 
  shale.
