  any 
  great 
  antiquity 
  of 
  trie 
  deposit, 
  characteristic 
  Pleistocene 
  forms- 
  

   being 
  absent 
  :

  Ranunculus

  Grays 
  (Essex). 
  

  

  The 
  plants 
  from 
  Grays 
  consist 
  of 
  a 
  number 
  of 
  leaves, 
  already 
  

   examined 
  by 
  Gaudin 
  and 
  Heer, 
  and 
  some 
  seeds 
  which 
  I 
  have 
  been 
  

   able 
  to 
  wash 
  out 
  of 
  the 
  lumps 
  of 
  clay. 
  The 
  leaves, 
  from 
  long 
  keep- 
  

   ing, 
  have 
  suffered 
  somewhat, 
  and 
  perhaps 
  to 
  this 
  cause 
  is 
  due 
  the 
  

   absence 
  of 
  certain 
  species 
  noted 
  in 
  a 
  MS. 
  list 
  by 
  Heer. 
  The 
  missing 
  

   plants 
  are 
  Pteris 
  aquilina?, 
  Vaccinium 
  myrtillus 
  1 
  ??, 
  an&Fagus 
  1 
  ??, 
  but 
  

   it 
  is 
  noticeable 
  that 
  Heer 
  records 
  all 
  three 
  with 
  doubt. 
  

  

  Ranunculus 
  repens, 
  L. 
  (seed). 
  

   Rubus 
  fruticosus, 
  L. 
  (seeds). 
  

   Rosa

  L. 
  (prickle). 
  

   Hedera 
  Helix, 
  L. 
  (leaves). 
  

   TJlmus 
  ? 
  (badly-preserved 
  leaves). 
  

   Alnus 
  glutinosa, 
  Gartn. 
  (leaA 
  r 
  es 
  and 
  cone). 
  

   Quercus 
  Robur, 
  L., 
  \ar. 
  sessiliflora 
  (leaves). 
  

   Corylus

   Popiclus,

   Salix

   Cyperus

   turn. 
  

  

  The 
  plants 
  occur 
  associated 
  with, 
  or 
  below 
  the 
  remains 
  of,, 
  

   mammoth 
  and 
  Corbicula 
  fluminalis. 
  They 
  point 
  distinctly 
  to 
  a 
  

   temperate 
  climate 
  and 
  mild 
  winters, 
  for 
  the 
  ivy 
  is 
  extremely 
  sensi- 
  

   tive 
  to 
  winter 
  cold. 
  Both 
  the 
  character 
  of 
  the 
  flora 
  and 
  the 
  position 
  

   of 
  the 
  deposit 
  suggest 
  correlation 
  with 
  the 
  temperate 
  plant-beds 
  of 
  

   Hoxne, 
  which 
  lie 
  between 
  the 
  Boulder 
  Clay 
  and 
  the 
  deposit 
  with 
  

   Arctic 
  species. 
  The 
  ivy 
  and 
  the 
  poplar 
  have 
  not 
  previously 
  been 
  

   recorded 
  as 
  British 
  fossils.
