  siderable 
  slip 
  of 
  the 
  upper 
  beds 
  over 
  this 
  slippery 
  floor 
  into 
  Eastweir 
  

   Bay. 
  

  

  Copt 
  Point 
  is 
  described 
  by 
  Dr. 
  Fitton* 
  as 
  being 
  130 
  feet 
  above 
  the 
  

   level 
  of 
  the 
  sea, 
  and 
  by 
  Mr. 
  Mr. 
  De 
  Kance 
  as 
  128 
  ft. 
  5 
  in. 
  

  

  In 
  the 
  autumn 
  of 
  1873 
  I 
  endeavoured 
  to 
  take 
  accurate 
  measure- 
  

   ments 
  of 
  the 
  Gault 
  at 
  Copt 
  Point 
  and 
  at 
  the 
  Pelterf, 
  a 
  local 
  name 
  

   given 
  to 
  a 
  part 
  of 
  Eastweir 
  Bay 
  where 
  the 
  upper 
  beds 
  occur 
  in 
  situ. 
  

  

  I 
  took 
  my 
  line 
  of 
  measurements 
  from 
  the 
  seam 
  of 
  nodules 
  of 
  sul- 
  

   phuret 
  of 
  iron, 
  the 
  base 
  of 
  the 
  Gault, 
  which 
  is 
  found 
  about 
  4 
  feet 
  

   above 
  a 
  hard 
  seam 
  of 
  sandstone, 
  the 
  zone 
  of 
  Ammonites 
  mammillatus 
  . 
  

   the 
  top 
  of 
  the 
  Upper 
  Neocomian, 
  the 
  intervening 
  four 
  feet 
  consisting 
  

   of 
  light 
  sands. 
  

  

  From 
  the 
  sulphuret-of-iron 
  band 
  up 
  to 
  the 
  base 
  of 
  the 
  Upper 
  Green- 
  

   sand 
  I 
  found 
  to 
  be 
  99 
  feet 
  4 
  inches. 
  

  

  The 
  Gault 
  is 
  divided 
  into 
  two 
  groups 
  or 
  divisions, 
  i. 
  e. 
  the 
  Upper 
  

   and 
  Lower 
  Gault, 
  separated 
  by 
  a 
  passage-bed 
  ; 
  and 
  these 
  divisions 
  may 
  

   be 
  again 
  subdivided 
  into 
  ten 
  well-defined 
  zones, 
  seven 
  being 
  below 
  

   and 
  three 
  above 
  the 
  nodule- 
  or 
  passage-bed, 
  as 
  shown 
  in 
  the 
  follow-

  A
