  Dr. 
  J. 
  W. 
  Gregory 
  was 
  glad 
  that 
  the 
  Authors 
  confirmed 
  

   Mr. 
  Etheridge's 
  determination 
  of 
  the 
  beds 
  as 
  Oxfordian 
  — 
  a 
  con- 
  

   clusion 
  based 
  on 
  the 
  collections 
  made 
  by 
  Mr. 
  Leigh 
  Smith. 
  The 
  

   simplicity 
  of 
  the 
  series 
  around 
  Elmwood 
  was 
  probably 
  due 
  to 
  its 
  

   occurrence 
  in 
  the 
  heart 
  of 
  a 
  great 
  plateau-area 
  ; 
  whereas 
  in 
  

   Western 
  Spitsbergen 
  the 
  series 
  was 
  more 
  varied, 
  owing 
  to 
  its 
  

   having 
  been 
  formed 
  on 
  the 
  oscillating 
  border 
  of 
  the 
  land-area. 
  

   Hence 
  it 
  is 
  probable 
  that 
  the 
  outlying 
  islands 
  of 
  the 
  Eranz 
  Josef 
  

   archipelago, 
  such 
  as 
  Oscar 
  Land 
  and 
  Petermann 
  Land, 
  will 
  yield 
  

   a 
  richer 
  series 
  of 
  deposits. 
  

  

  The 
  main 
  interest 
  of 
  the 
  stratigraphical 
  portion 
  of 
  the 
  paper 
  was 
  

   centred 
  in 
  the 
  history 
  of 
  the 
  Arctic 
  Jurassic 
  sea 
  ; 
  but 
  the 
  speaker 
  

   thought 
  that 
  Neumayr's 
  fascinating 
  theory, 
  to 
  which 
  reference 
  

   had 
  been 
  made, 
  was 
  now 
  quite 
  untenable. 
  The 
  relations 
  of 
  the 
  

   Jurassic 
  series 
  in 
  Eranz 
  Josef 
  Land 
  to 
  those 
  of 
  the 
  Northern 
  

   Petchora 
  basin 
  were 
  very 
  significant. 
  He 
  understood 
  that 
  Belemnites 
  

   Panderi 
  was 
  typically 
  Kimmeridgian 
  and 
  Sequanian. 
  He 
  thought 
  

   that 
  all 
  Eellows 
  of 
  the 
  Society 
  would 
  be 
  grateful 
  to 
  Mr. 
  Harmsworth 
  

   for 
  his 
  munificent 
  generosity, 
  and 
  to 
  the 
  Authors 
  for 
  their 
  very 
  

   careful 
  and 
  thorough 
  study 
  of 
  the 
  material 
  collected. 
  

  

  Mr. 
  W. 
  W. 
  Watts 
  enquired 
  as 
  to 
  whether 
  it 
  was 
  absolutely 
  

   certain 
  that 
  the 
  basalts 
  were 
  other 
  than 
  of 
  Tertiary 
  age.
