﻿NUMMULITIC 
  OR 
  EOCENE 
  GROUP. 
  95 
  

  

  a 
  tolerable 
  section. 
  On 
  the 
  North 
  bank 
  of 
  the 
  stream, 
  where 
  it 
  cuts 
  

   the 
  tail 
  of 
  the 
  range, 
  the 
  Nummulitic 
  limestone 
  is 
  seen 
  in 
  its 
  wonted 
  

   position 
  on 
  the 
  hill 
  side, 
  dipping 
  about 
  80° 
  between 
  North-east 
  and 
  

   East-north-east, 
  but 
  much 
  broken 
  up 
  into 
  loose 
  masses 
  as 
  it 
  ap- 
  

   proaches 
  the 
  stream. 
  The 
  limestone 
  tails 
  down, 
  however, 
  in 
  a 
  sort 
  

   of 
  spit 
  to 
  within 
  some 
  twenty 
  yards 
  or 
  less 
  of 
  the 
  bank 
  of 
  the 
  stream, 
  

   when 
  it 
  disappears, 
  and 
  would 
  seem 
  to 
  die 
  out, 
  as 
  it 
  certainly 
  does 
  

   not 
  reappear 
  on 
  the 
  opposite 
  bank, 
  where 
  sandstones 
  and 
  shales 
  are 
  

   alone 
  visible. 
  Lower 
  down 
  the 
  stream 
  to 
  the 
  Eastward, 
  a 
  great 
  thick- 
  

   ness 
  of 
  bluish 
  shales 
  without 
  fossils, 
  comes 
  in, 
  which 
  I 
  consider 
  as 
  

   identical 
  with 
  the 
  Sitsyahn 
  shales, 
  and 
  which 
  are 
  here 
  nearly 
  vertical 
  

   and 
  much 
  disturbed. 
  On 
  the 
  South 
  bank 
  of 
  the 
  stream, 
  in 
  the 
  spot 
  

   where 
  the 
  Nummulitic 
  limestone, 
  if 
  continued, 
  might 
  be 
  expected 
  to 
  

   appear, 
  sandstones 
  only 
  are 
  seen, 
  some 
  of 
  which 
  display 
  carbonaceous 
  

   markings 
  ; 
  and 
  one 
  bed 
  was 
  an 
  intensely 
  hard 
  grit, 
  containing 
  small 
  

   shark's 
  teeth, 
  and 
  the 
  cast 
  of 
  a 
  large 
  CeritAium-like 
  shell, 
  the 
  size 
  

   and 
  proportion 
  of 
  the 
  living 
  Terebralia 
  telescopium. 
  Between 
  these 
  

   presumedly 
  Nummulitic 
  sandstones 
  and 
  the 
  overlying 
  shales, 
  I 
  could 
  

   detect 
  no 
  break, 
  and 
  I 
  believe 
  the 
  explanation 
  of 
  the 
  absence 
  of 
  the 
  

   Nummulitic 
  limestone 
  from 
  this 
  section, 
  is 
  due 
  simply 
  to 
  that 
  rock 
  

   at 
  this 
  spot 
  dying 
  out, 
  a 
  similar 
  instance 
  of 
  which 
  I 
  shall 
  presently 
  

   describe. 
  

  

  West 
  of 
  this 
  range 
  flows 
  the 
  Pani 
  stream, 
  for 
  about 
  seven 
  miles 
  

   below 
  the 
  frontier, 
  in 
  a 
  sort 
  of 
  trough, 
  or 
  what 
  may 
  be 
  considered 
  as 
  

   an 
  irregular 
  synclinal 
  of 
  Nummulitic 
  strata. 
  West 
  of 
  the 
  Pani 
  stream, 
  

   Nummulitic 
  limestone 
  occurs 
  plentifully 
  at 
  many 
  places 
  near 
  the 
  river, 
  

   not 
  only 
  developed 
  largely 
  on 
  the 
  surface 
  of 
  the 
  ground, 
  but 
  as 
  a 
  

   distinct 
  ridge, 
  which, 
  though 
  not 
  continuous, 
  may 
  be 
  traced 
  with 
  

   occasional 
  breaks 
  for 
  about 
  twelve 
  miles. 
  The 
  limestone 
  of 
  this 
  ridge 
  

   is 
  the 
  same 
  bed 
  as 
  that 
  described 
  near 
  Phoungaeing, 
  and 
  like 
  it, 
  ends 
  

   or 
  commences 
  abruptly 
  about 
  one 
  and 
  three-quarter 
  miles 
  South 
  of
