  Section 
  IX. 
  (of 
  the 
  interesting 
  exposure 
  at 
  Burton 
  Bradstock) 
  

   exhibits 
  the 
  junction 
  of 
  Inferior- 
  Oolite 
  Limestone 
  and 
  the 
  Yeovil 
  

   Sands. 
  With 
  our 
  knowledge 
  of 
  the 
  Cotteswold 
  Cephalopoda-bed 
  we 
  

   see 
  that 
  we 
  have 
  here 
  a 
  higher 
  horizon 
  than 
  at 
  Bradford 
  Abbas, 
  

   Stoford, 
  &c. 
  — 
  and 
  a 
  horizon 
  absent 
  from 
  those 
  places. 
  Read 
  in 
  

   conjunction 
  with 
  the 
  other 
  sections 
  of 
  yellow 
  sands 
  south 
  of 
  the 
  

   Mendips, 
  we 
  obtain 
  the 
  knowledge 
  that 
  the 
  yellow 
  micaceous 
  sands 
  

   of 
  this 
  area 
  (the 
  Yeovil 
  Sands) 
  are 
  on 
  exactly 
  the 
  same 
  horizon 
  

   as 
  the 
  two 
  upper 
  divisions 
  of 
  the 
  Cotteswold 
  Cephalopoda-bed 
  (the 
  

   Durnortieria- 
  and 
  Moorei-beds) 
  and 
  also 
  as 
  part 
  of 
  the 
  " 
  Sandy 
  

   ferruginous 
  Limestone."
