  the 
  same 
  time, 
  and 
  in 
  the 
  same 
  Journal, 
  was 
  published 
  a 
  description 
  of 
  

   the 
  islet 
  by 
  Lieutenant 
  Fulljames. 
  In 
  the 
  December 
  number 
  of 
  the 
  

   volume, 
  there 
  are 
  some 
  ' 
  geological 
  notes 
  ' 
  by 
  Dr. 
  Lush, 
  which 
  relate 
  

   in 
  part 
  to 
  the 
  islet 
  of 
  Piram 
  and 
  neighbouring 
  coast. 
  

  

  In 
  1845 
  Dr. 
  Falconer 
  read 
  a 
  paper 
  before 
  the 
  British 
  Association 
  on 
  

   some 
  Piram 
  fossils 
  collected 
  by 
  Fulljames 
  ; 
  and 
  

   later 
  in 
  the 
  same 
  year 
  he 
  published, 
  in 
  the 
  Quarter- 
  

   ly 
  Journal 
  of 
  the 
  Geological 
  Society 
  of 
  London, 
  a 
  fuller 
  description 
  of 
  

   the 
  Piram 
  fossils, 
  together 
  with 
  extracts 
  from 
  the 
  papers 
  above 
  men- 
  

   tioned 
  regarding 
  the 
  structure 
  of 
  the 
  island 
  and 
  opposite 
  coast. 
  

  

  In 
  the 
  year 
  1857, 
  Mr. 
  Theobald, 
  late 
  of 
  the 
  Geological 
  Survey 
  of 
  

  

  India, 
  examined 
  a 
  portion 
  of 
  the 
  country 
  border-

  mg 
  the 
  southern 
  and 
  eastern 
  coasts, 
  but 
  his 
  report 
  

  

  was 
  not 
  published, 
  and 
  therefore 
  need 
  not 
  be 
  taken 
  in 
  review. 
  But 
  

  

  since 
  it 
  was 
  the 
  authority 
  for 
  the 
  statement 
  in 
  the 
  ' 
  Manual 
  of 
  the 
  

  

  Geology 
  of 
  India 
  ' 
  (p. 
  342), 
  that 
  nummulitic 
  limestone 
  occurs 
  in 
  

  

  Kathiawar, 
  I 
  may 
  here 
  mention 
  that 
  no 
  such 
  rock 
  has 
  been 
  met 
  with 
  

  

  by 
  me 
  in 
  the 
  province. 
  None 
  of 
  the 
  tertiary 
  rocks 
  exposed 
  can 
  be 
  of 
  

  

  earlier 
  age 
  than 
  miocene. 
  

  

  It 
  has 
  been 
  stated 
  from 
  time 
  to 
  time, 
  in 
  sundry 
  reports 
  and 
  gazet- 
  

   teers, 
  that 
  the 
  Girnar 
  of 
  the 
  Junagarh 
  hills 
  is 
  a 
  mass 
  of 
  granite 
  ; 
  this 
  

   too 
  is 
  erroneous 
  : 
  the 
  Girnar 
  mountain 
  is 
  composed 
  mostly 
  of 
  diorite 
  (a 
  

   black 
  and 
  white 
  crystalline 
  granular 
  rock 
  of 
  hornblende 
  and 
  felspar) 
  and 
  

   of 
  mica 
  diorite. 
  There 
  is 
  no 
  granite 
  in 
  any 
  part 
  of 
  the 
  country. 
  

  

  In 
  February 
  1863, 
  Mr. 
  W. 
  T. 
  Blanford 
  made 
  a 
  visit 
  to 
  the 
  island 
  of 
  

  

  Piram, 
  and 
  published 
  a 
  note 
  on 
  the 
  subject 
  at 
  the 
  

   Blanford. 
  

  

  end 
  of 
  his 
  memoir 
  * 
  on 
  the 
  geology 
  of 
  Western 
  

  

  India 
  (issued, 
  January 
  1869). 
  The 
  chief 
  object 
  of 
  his 
  visit 
  being 
  "for 
  

  

  the 
  purpose 
  of 
  endeavouring 
  to 
  ascertain 
  if 
  the 
  beds 
  there 
  existing, 
  

  

  which 
  from 
  their 
  mammalian 
  fauna 
  are 
  considered 
  of 
  miocene 
  age 
  by 
  

  

  Falconer, 
  presented 
  any 
  marked 
  resemblance 
  to 
  the 
  upper 
  beds 
  in' 
  the 
  

  

  Oomrawattee, 
  Keen, 
  and 
  Taptee 
  rivers."
