  present 
  to 
  alter 
  them, 
  even 
  were 
  there 
  any 
  chance 
  of 
  such 
  a 
  proposal 
  

   finding 
  favour; 
  but 
  I 
  would 
  submit, 
  as 
  well 
  worthy 
  the 
  consideration 
  of 
  

   this 
  Society, 
  whether, 
  as 
  the 
  very 
  existence 
  of 
  these 
  vast 
  series 
  of 
  plant- 
  

   remains 
  was 
  unknown 
  when 
  the 
  present 
  classification 
  was 
  established, 
  

   the 
  time 
  has 
  not 
  almost 
  arrived 
  to 
  introduce 
  a 
  separate 
  classification 
  

   for 
  plant-remains, 
  which 
  the 
  impossibility 
  of 
  applying 
  the 
  present 
  one 
  

   to 
  them 
  seems 
  to 
  render 
  necessary. 
  The 
  classification 
  for 
  terrestrial 
  

   conditions 
  and 
  for 
  marine 
  conditions 
  may 
  with 
  advantage 
  be 
  kept 
  

   distinct 
  until 
  our 
  knowledge 
  is 
  sufficient 
  to 
  enable 
  us 
  to 
  correlate 
  them 
  

   satisfactorily. 
  Otherwise 
  it 
  may 
  be 
  a 
  very 
  long 
  time 
  before 
  confusion 
  

   ceases 
  ; 
  for 
  I 
  may 
  venture 
  to 
  say 
  that 
  the 
  flora 
  at 
  Bournemouth, 
  which 
  

   stratigraphical 
  evidence 
  of 
  the 
  most 
  unequivocal 
  description 
  compels 
  

   us 
  to 
  place 
  at 
  the 
  very 
  base 
  of 
  what 
  is 
  known 
  as 
  our 
  Middle 
  Eocene, 
  

   would 
  have 
  been, 
  if 
  inference 
  is 
  permissible 
  from 
  their 
  published 
  

   work, 
  regarded 
  by 
  Prof. 
  Heer 
  as 
  Lower 
  Miocene, 
  by 
  the 
  Marquis 
  of 
  

   Saporta 
  as 
  Oligocene, 
  by 
  Baron 
  von 
  Ettingshausen 
  and 
  Prof. 
  Lesque- 
  

   reux 
  as 
  Eocene, 
  and, 
  perhaps, 
  by 
  Prof. 
  Newberry 
  as 
  Cretaceous. 
  

   With 
  less 
  known, 
  more 
  isolated, 
  and 
  less 
  distinctive 
  floras 
  the 
  diver- 
  

   gence 
  of 
  opinion 
  would, 
  doubtless, 
  be 
  greater. 
  "We 
  have 
  only 
  to 
  

   realize 
  the 
  vast 
  difference, 
  not 
  only 
  stratigraphically, 
  but 
  in 
  the 
  con- 
  

   ditions 
  of 
  life 
  upon 
  the 
  earth, 
  which 
  this 
  discrepancy 
  implies, 
  to 
  see 
  

   the 
  great 
  inconvenience 
  that 
  must 
  be 
  caused 
  to 
  science 
  through 
  it. 
  

  

  Discussion. 
  

  

  Mr. 
  Koch 
  stated 
  that 
  the 
  Mull 
  beds 
  contained 
  leaves 
  which 
  very 
  

   closely 
  resembled 
  some 
  of 
  Mr. 
  Gardner's 
  drawings. 
  

  

  Prof. 
  Judi) 
  remarked 
  that 
  Mr. 
  Gardner's 
  researches 
  pointed 
  to 
  the 
  

   necessity 
  for 
  distinct 
  classifications 
  based 
  on 
  terrestrial 
  and 
  on 
  

   marine 
  forms 
  respectively. 
  

  

  Prof. 
  Hughes 
  pointed 
  out 
  that 
  in 
  the 
  case 
  of 
  some 
  of 
  the 
  beds 
  re- 
  

   ferred 
  to 
  there 
  could 
  be 
  no 
  comparison 
  such 
  as 
  that 
  suggested 
  by 
  

   Prof. 
  Judd, 
  as 
  some 
  contained 
  remains 
  of 
  plants 
  only, 
  and 
  no 
  marine 
  

   testaceous 
  mollusca. 
  

  

  Mr. 
  Gardner 
  thought 
  that 
  the 
  greatest 
  separation 
  in 
  the 
  Eocene 
  

   formation 
  existed 
  between 
  the 
  Bracklesham 
  .and 
  Barton 
  series 
  rather 
  

   than 
  between 
  the 
  Barton 
  and 
  the 
  later 
  series 
  ; 
  but 
  he 
  thought 
  this 
  

   change 
  was 
  a 
  purely 
  local 
  one 
  in 
  the 
  British 
  area.
