  Two 
  things 
  contribute 
  to 
  show 
  that 
  this 
  Selsea 
  bed 
  (e 
  of 
  the 
  

   diagram) 
  was 
  not 
  due 
  to 
  the 
  retiring 
  sea 
  of 
  the 
  great 
  glaciation 
  — 
  

   one 
  the 
  presence 
  of 
  shells, 
  the 
  beds 
  of 
  that 
  glaciation 
  in 
  Hampshire 
  

   being 
  destitute 
  of 
  them 
  ; 
  and 
  the 
  other 
  the 
  fact 
  stated 
  by 
  Mr. 
  

   Godwin- 
  Austen, 
  and 
  shown 
  in 
  his 
  diagram 
  section, 
  that 
  this 
  bed 
  is 
  

   unconformable 
  to 
  the 
  gravel 
  of 
  the 
  Hampshire 
  inlet, 
  termed 
  by 
  him 
  

   the 
  " 
  lower 
  red 
  gravel," 
  and 
  corresponding 
  to 
  / 
  of 
  my 
  figures, 
  of 
  

   which 
  I 
  have 
  traced 
  the 
  emergence. 
  

  

  This 
  unconformity, 
  if 
  it 
  do 
  not 
  prove 
  redepression, 
  is 
  at 
  any 
  rate 
  

   very 
  consistent 
  with 
  it 
  ; 
  and 
  the 
  presence 
  of 
  mammalian 
  remains 
  

   associated 
  with 
  the 
  marine 
  Mollusca 
  in 
  this 
  bed 
  is 
  much 
  more 
  con- 
  

   sistent 
  with 
  its 
  accumulation 
  when 
  near 
  to 
  land, 
  and 
  covered 
  by 
  no 
  

   great 
  depth 
  of 
  water, 
  than 
  when 
  the 
  sea 
  was 
  more 
  than 
  twenty 
  

   fathoms 
  deep 
  over 
  it, 
  and 
  the 
  shore 
  at 
  least 
  nine 
  miles 
  to 
  the 
  north 
  

   of 
  it, 
  as 
  it 
  must 
  have 
  been 
  when 
  the 
  Bourne-Common 
  and 
  Avisford 
  

   beds 
  accumulated. 
  

  

  The 
  position 
  occupied 
  by 
  the 
  group 
  of 
  beds 
  in 
  the 
  foregoing 
  dia- 
  

   gram 
  section 
  relatively 
  to 
  the 
  gravel

  great 
  submergence

   major 
  glaciation,

  is

  the

   if 
  the 
  bed 
  G 
  in 
  that

  be 
  (for 
  this 
  purpose)
