  PREFACE. 
  

  

  ITmia, 
  There 
  seems 
  to 
  me 
  very 
  little 
  room 
  for 
  doubt 
  that 
  

   the 
  Nimar-sandstone 
  is 
  of 
  upper 
  Gondwana 
  age, 
  and 
  there- 
  

   fore 
  Jurassic, 
  not 
  cretaceous. 
  The 
  probabilities 
  of 
  the 
  case 
  

   were 
  duly 
  pointed 
  out 
  to 
  Mr. 
  Bose, 
  but 
  as 
  he 
  had 
  been 
  over 
  

   the 
  ground 
  and 
  I 
  had 
  not, 
  I 
  did 
  not 
  insist. 
  He 
  seems 
  to 
  

   have 
  been 
  fascinated 
  with 
  the 
  idea 
  of 
  making 
  up 
  a 
  symmetri- 
  

   cal 
  cretaceous 
  system 
  — 
  a 
  fatal 
  proclivity 
  that 
  is 
  apparent 
  in 
  

   other 
  parts 
  of 
  his 
  memoir.
