  Although 
  we 
  have 
  no 
  means 
  as 
  yet 
  of 
  exactly 
  correlating 
  the 
  

   Saint-Cross 
  beds 
  with 
  those 
  at 
  Hoxne, 
  it 
  would 
  not, 
  I 
  think, 
  be 
  well 
  

   to 
  close 
  these 
  notes 
  without 
  some 
  further 
  reference 
  to 
  the 
  latter 
  

   deposits. 
  For 
  purposes 
  of 
  ready 
  comparison, 
  I 
  give 
  one 
  of 
  Professor 
  

   PrestTvich's 
  sections 
  as 
  quoted 
  by 
  Messrs. 
  C. 
  Reid 
  and 
  H. 
  X. 
  Ridley 
  

   in 
  an 
  interesting 
  paper 
  read 
  at 
  the 
  Bath 
  meeting 
  of 
  the 
  British 
  

   Association

  On 
  comparing 
  this 
  section 
  with 
  the 
  description 
  of 
  the 
  Saint-Cross 
  

   beds, 
  it 
  will 
  be 
  seen 
  that 
  in 
  lithological 
  character, 
  if 
  not 
  in 
  order 
  of 
  

   sequence, 
  there 
  is 
  a 
  strong 
  general 
  resemblance 
  between 
  the 
  two 
  

   series. 
  Indeed, 
  I 
  believe 
  that 
  no 
  one 
  who 
  is 
  familiar 
  with 
  the 
  

   Hoxne 
  sections, 
  and 
  who 
  will 
  examine 
  the 
  beds 
  at 
  Saint 
  Cross, 
  will 
  

   fail 
  to 
  conclude 
  that 
  both 
  the 
  deposits 
  were 
  formed 
  under 
  very 
  

   similar, 
  if 
  not 
  identical, 
  conditions. 
  In 
  comparing 
  the 
  fossil 
  

   contents 
  of 
  the 
  two 
  formations 
  one 
  with 
  another 
  there 
  is, 
  with 
  one 
  

   exception, 
  little 
  to 
  call 
  for 
  remark. 
  A 
  greater 
  number 
  of 
  species 
  

   have 
  certainly 
  been 
  found 
  at 
  Hoxne 
  than 
  at 
  Saint 
  Cross 
  ; 
  but 
  this 
  

   is 
  only 
  natural, 
  seeing 
  that 
  the 
  one 
  deposit 
  has 
  been 
  known 
  for 
  

   nearly 
  a 
  century, 
  the 
  other 
  for 
  scarcely 
  a 
  year. 
  Messrs. 
  Reid 
  and 
  

   Ridley, 
  in 
  their 
  paper 
  already 
  referred 
  to, 
  give 
  a 
  list 
  of 
  38 
  plants 
  

   found 
  by 
  them 
  in 
  bed 
  d 
  of 
  the 
  Hoxne 
  section, 
  including 
  Betulanana, 
  

   Saliv 
  polaris, 
  S. 
  Myrsinites, 
  and 
  the 
  alpine 
  moss 
  Acroceratium 
  

   sarmentosum. 
  On 
  placing 
  this 
  list 
  side 
  by 
  side 
  with 
  that 
  of 
  the 
  

   plants 
  found 
  in 
  bed 
  d 
  at 
  Saint 
  Cross, 
  it 
  will 
  at 
  once 
  be 
  noticed 
  

   that 
  the 
  group 
  of 
  northern 
  and 
  arctic 
  species 
  is 
  missing 
  from 
  the 
  

   latter. 
  But 
  it 
  must 
  be 
  remembered 
  that 
  Messrs. 
  Reid 
  and 
  Ridley 
  

   determined 
  the 
  northern 
  birch 
  and 
  willows 
  from 
  leaves 
  which 
  they 
  

   found 
  in 
  finely 
  bedded 
  clay, 
  possessing 
  far 
  higher 
  preserving 
  powers 
  

   than 
  the 
  Saint-Cross 
  bed 
  d. 
  Until 
  we 
  meet 
  at 
  Saint 
  Cross
