  the

   glomerate 
  is 
  described 
  to 
  be 
  about 
  3 
  feet, 
  although, 
  in 
  general, 
  they 
  do 
  

   not

  These 
  sections

  of 
  no 
  value 
  as 
  indicating 
  any 
  regular 
  suc- 
  

   cession 
  of 
  strata 
  ; 
  the 
  little 
  island 
  consisting 
  merely 
  of 
  a 
  number 
  of 
  

   conglomeratic 
  beds, 
  alternating 
  with 
  soft 
  sandy 
  silts 
  and 
  silty 
  shales. 
  

   Some 
  of 
  the 
  conglomerates 
  are 
  very 
  coarse, 
  with 
  large 
  imbedded 
  lumps 
  

   of 
  a 
  yellowish, 
  or 
  greyish-brown 
  sandstone 
  ; 
  others 
  are 
  composed 
  mostly 
  

   of 
  concretionary 
  sandy 
  nodules, 
  often 
  black 
  in 
  colour, 
  some 
  of 
  them 
  very 
  

   large 
  and 
  assuming 
  queer 
  fantastic 
  shapes.

  Mr. 
  Blanford 
  observes 
  (Mem. 
  8eol. 
  Sur. 
  Ind., 
  Vol. 
  VI, 
  p. 
  374), 
  "The 
  conglomerates 
  

   belong 
  to 
  two 
  forms, 
  very 
  distinct 
  in 
  appearance, 
  but 
  both 
  containing 
  bones. 
  The 
  most 
  pre- 
  

   valent 
  is 
  an 
  extremely 
  coarse 
  rock, 
  made 
  up 
  of 
  rounded 
  blocks 
  of 
  sandstone, 
  varying 
  from 
  

   3 
  feet 
  in 
  diameter 
  downwards, 
  but 
  mostly 
  not 
  exceeding 
  a 
  foot, 
  and 
  very 
  irregularly 
  shaped. 
  

   The 
  sandstone 
  is 
  generally 
  of 
  fine 
  texture, 
  and 
  grey 
  or 
  light 
  brown 
  in 
  colour. 
  This 
  conglo- 
  

   merate 
  is 
  usually 
  more 
  or 
  less 
  nodular, 
  and 
  occasionally 
  the 
  bed 
  appears 
  chiefly 
  made 
  up 
  of 
  

   nodular 
  concretionary 
  pebbles, 
  which, 
  when 
  weathered, 
  strongly 
  resemble 
  casts 
  of 
  large 
  

   univalve 
  shells. 
  The 
  matrix 
  of 
  the 
  pebbles 
  which 
  form 
  the 
  bulk 
  of 
  the 
  rock 
  is
