  REV. 
  W. 
  DOWNES 
  ON 
  THE 
  BLACKDOWN 
  BEDS. 
  

  

  omissions 
  * 
  in 
  it 
  which 
  required 
  to 
  be 
  corrected 
  or 
  supplied, 
  while 
  

   at 
  the 
  same 
  time 
  fresh 
  facts 
  began 
  to 
  accumulate. 
  I 
  purpose 
  there- 
  

   fore 
  in 
  the 
  present 
  paper 
  to 
  bring 
  forward 
  in 
  part 
  the 
  same 
  sub- 
  

   ject, 
  but, 
  it 
  is 
  hoped, 
  dealt 
  with 
  more 
  accurately 
  and 
  fully. 
  

  

  In 
  addition, 
  moreover, 
  to 
  the 
  compilation 
  of 
  a 
  list 
  of 
  Blackdown 
  

   fossils 
  from 
  those 
  scattered 
  about 
  in 
  collections 
  and 
  Museums, 
  the 
  

   attempt 
  will 
  be 
  made 
  in 
  the 
  present 
  paper 
  to 
  refer 
  them 
  severally 
  

   to 
  the 
  zones 
  to 
  which 
  they 
  belong, 
  so 
  far 
  as 
  this 
  has 
  proved 
  to 
  be 
  

   practicable, 
  and 
  to 
  compare 
  the 
  zones 
  thus 
  identified 
  with 
  similar 
  

   zones 
  at 
  Haldon, 
  in 
  so 
  far 
  as 
  a 
  similarity 
  exists. 
  

  

  Literature 
  of 
  the 
  Subject. 
  

  

  The 
  literature 
  more 
  or 
  less 
  bearing 
  upon 
  the 
  subject 
  of 
  Blackdown 
  

   is 
  very 
  voluminous 
  ; 
  and 
  it 
  is 
  possible 
  that 
  some 
  of 
  it 
  may 
  have 
  

   escaped 
  me. 
  The 
  following 
  works, 
  however, 
  have 
  been 
  consulted, 
  

   and 
  more 
  or 
  less 
  referred 
  to.
