  also 
  noticed 
  the 
  occurrence 
  of 
  beds 
  of 
  

  

  gritty 
  sandstone 
  a 
  few 
  miles 
  west 
  of 
  Poonainallee 
  on 
  the 
  Madras- 
  Arcot 
  

  

  road. 
  This 
  sandstone 
  was, 
  however, 
  referred 
  by 
  him 
  to 
  the 
  Cuddalore 
  

  

  sandstone 
  series, 
  and 
  not 
  to 
  the 
  ' 
  Plant 
  shale 
  ' 
  series, 
  to 
  which, 
  however, 
  

  

  they 
  are 
  shown 
  to 
  belong 
  by 
  the 
  plant 
  remains 
  discovered 
  in 
  them.

  of 
  500 
  

  

  feet
