  The 
  mineral 
  character 
  and 
  general 
  appearance 
  of 
  the 
  limestone 
  has 
  been 
  

   well 
  described 
  by 
  Mr. 
  Blanford

  " 
  It 
  is 
  yellow 
  or 
  red 
  in 
  colour 
  (the 
  former 
  tint 
  being 
  doubtless 
  due 
  

   to 
  some 
  carbonate 
  of 
  iron, 
  in 
  the 
  limestone 
  exposed 
  to 
  the 
  air, 
  being 
  con- 
  

   verted 
  into 
  peroxide), 
  and 
  consists 
  chiefly 
  of 
  small 
  fragments 
  of 
  Bryozoa, 
  

   shells, 
  &c. 
  The 
  fresh 
  broken 
  surface 
  has 
  a 
  somewhat 
  granular 
  mottled 
  

   appearance, 
  and 
  the 
  fossils 
  are 
  not 
  conspicuous 
  ; 
  they 
  weather 
  out 
  on 
  

   exposure. 
  In 
  many 
  places 
  this 
  bed 
  is 
  obliquely 
  laminated/' 
  

  

  The 
  limestone, 
  though 
  it 
  rolls 
  about 
  at 
  places, 
  is, 
  like 
  the 
  two 
  groups 
  

   described 
  in 
  the 
  previous 
  sections, 
  as 
  a 
  rule, 
  horizontal.

  they 
  are 
  all 
  carried 
  with 
  the 
  same 
  dip, 
  which 
  is 
  northerly 
  and 
  

   amounts 
  to 
  about 
  15°, 
  and 
  are 
  faulted 
  against 
  the 
  Nimar 
  sandstone.

   South 
  of 
  Raherda, 
  only 
  4 
  miles 
  further 
  north, 
  they 
  dip 
  southward 
  at 
  

   about 
  the 
  same 
  angle.

  This

  perhaps, 
  too 
  small
