  Comparison 
  between 
  the 
  Great 
  Oolite 
  and 
  Cornbrash 
  of 
  Nor- 
  

   thamptonshire 
  is 
  given 
  in 
  the 
  above 
  Table. 
  The 
  -last 
  column 
  for 
  

   Yorkshire 
  is 
  added 
  for 
  comparison, 
  and 
  will 
  show 
  how 
  much 
  richer 
  

  

  the 
  Northern 
  Cornbrash 
  than 
  that 
  of 
  Northamptonshire 
  &c. 
  

  

  The 
  absence 
  of 
  corals 
  may 
  account 
  for 
  the 
  non-oolitic 
  character 
  

   of 
  the 
  Great-Oolite 
  Limestones, 
  a 
  marked 
  feature 
  throughout 
  the 
  

   series 
  under 
  notice. 
  

  

  Cornbrash. 
  — 
  It 
  is 
  doubtful 
  whether 
  the 
  Cornbrash 
  of 
  Yorkshire 
  

   is 
  on 
  precisely 
  the 
  same 
  horizon 
  as 
  that 
  of 
  Lincolnshire 
  and 
  North- 
  

   amptonshire. 
  It 
  retains 
  its 
  general 
  and 
  uniform 
  limestone 
  cha- 
  

   racter 
  from 
  Dorsetshire 
  and 
  Gloucestershire, 
  and 
  disappears 
  under 
  

   this 
  condition 
  before 
  reaching 
  the 
  Humber. 
  At 
  Brigg 
  it 
  is 
  hardly 
  

   distinguishable 
  from 
  the 
  thin 
  overlying 
  Kellaways 
  Rock, 
  both 
  hori- 
  

   zons 
  not 
  being 
  5 
  feet 
  thick. 
  Prof. 
  Phillips 
  fully 
  notices
