  rest 
  upon 
  metamorphics 
  ; 
  patches 
  of 
  the 
  coralline 
  limestone,, 
  however, 
  too 
  

   insignificant 
  to 
  be 
  mapped, 
  crop 
  out 
  here 
  and 
  there 
  along 
  the 
  southern 
  

   bank 
  of 
  the 
  river. 
  And 
  opposite 
  Kachaoda 
  this 
  limestone 
  is 
  seen, 
  

   with 
  its 
  thickness 
  and 
  extent 
  considerably 
  increased, 
  to 
  pass 
  under 
  

   the 
  trap, 
  east 
  of 
  a 
  stream 
  which 
  passes 
  by 
  Deoli. 
  But 
  immediately 
  

   south 
  and 
  west 
  of 
  that 
  stream, 
  for 
  nearly 
  half 
  a 
  mile, 
  along 
  both 
  sides 
  

   of 
  the 
  Man, 
  the 
  basaltic 
  series 
  immediately 
  overlie 
  the 
  metamorphic. 
  

   Between 
  Kachaoda 
  and 
  Ghursul, 
  the 
  pre-trappean 
  cretaceous 
  surface 
  

   is 
  extremely 
  irregular. 
  Immediately 
  south, 
  north, 
  and 
  east 
  of 
  Ghursul, 
  

   however, 
  perfect 
  regularity 
  prevails 
  — 
  the 
  metamorphics, 
  sandstones, 
  

   limestones, 
  and 
  trap, 
  succeeding 
  each 
  other 
  in 
  stratigraphical 
  order. 
  

  

  The 
  metamorphics 
  were 
  distinctly 
  seen 
  below 
  the 
  trap 
  at 
  Tanda. 
  

   But 
  beyond 
  a 
  mile 
  or 
  two 
  of 
  that 
  town 
  in 
  every 
  direction, 
  except 
  the 
  

   northern 
  (not 
  examined), 
  calcareous 
  and 
  arenaceous 
  strata 
  (usually 
  not 
  

   more 
  than 
  5 
  to 
  10 
  feet 
  in 
  thickness) 
  intervene 
  at 
  places 
  very 
  little 
  

   apart. 
  The 
  interposition 
  becomes 
  more 
  and 
  more 
  constant 
  southwards, 
  

   until, 
  as 
  at 
  Anjantar, 
  Iskiapura, 
  &c, 
  the 
  presence 
  of 
  pre-Lameta 
  creta- 
  

   ceous 
  limestone 
  is 
  invariably 
  noticed 
  wherever 
  the 
  base 
  of 
  the 
  trap 
  is 
  

   exposed. 
  In 
  the 
  neighbourhood 
  of 
  Bag, 
  to 
  its 
  east, 
  as 
  at 
  Deodha, 
  the 
  

   trap 
  rests 
  directly 
  upon 
  Nimar 
  sandstone, 
  but 
  within 
  a 
  mile 
  or 
  two 
  

   southward, 
  upon 
  coralline 
  limestone. 
  West 
  and 
  north-west 
  of 
  Bag 
  the 
  

   trap 
  usually 
  rests 
  upon 
  the 
  Lametas. 
  

  

  Inter-trappeans. 
  — 
  The 
  inter-trappeans 
  near 
  Punassa 
  have 
  been 
  

   already 
  alluded 
  to. 
  The 
  fossils 
  yielded 
  by 
  them 
  are 
  mainly 
  Cypris 
  and 
  

   Physa. 
  Near 
  Barwai, 
  at 
  Rupabari, 
  the 
  latter 
  genus 
  occurs 
  almost 
  

   exclusively. 
  The 
  shells 
  at 
  the 
  top 
  of 
  the 
  inter-trappean 
  limestone, 
  i. 
  e., 
  

   close 
  to 
  its 
  junction 
  with 
  the 
  trap, 
  are 
  considerably 
  flattened. 
  Small 
  

   patches 
  of 
  the 
  limestone 
  occur 
  near 
  Gujri 
  and 
  Dharampuri. 
  Here 
  

   more 
  than 
  one 
  species 
  of 
  JJnio 
  occur 
  along 
  with 
  Physa 
  prinsepii. 
  

  

  The 
  inter-trappeans 
  are 
  nowhere 
  of 
  any 
  great 
  thickness 
  — 
  10 
  feet 
  

   would 
  be 
  the 
  average 
  ; 
  nor 
  do 
  they 
  ever 
  extend 
  far 
  ; 
  and 
  they 
  invari- 
  

   ably 
  occur 
  in 
  the 
  valley 
  towards 
  the 
  base 
  of 
  the 
  trap 
  series. 
  None 
  but 
  

   fresh-water 
  fossils 
  have 
  been 
  met 
  with 
  in 
  the 
  area 
  surveyed.
