   some

  As 
  regards 
  the 
  horizons 
  present 
  in 
  Kent, 
  the 
  plant-remains 
  

   indicate 
  that, 
  in 
  the 
  area 
  so 
  far 
  proved, 
  only 
  Middle 
  or 
  Transition 
  

   Coal 
  Measures, 
  or

  occur.

  The 
  gravel 
  at 
  Piltdown 
  (Sussex) 
  below 
  the 
  surface-soil 
  is 
  divided 
  

   into 
  three 
  distinct 
  beds 
  : 
  — 
  

  

  The 
  first, 
  or 
  uppermost, 
  contains 
  subangular 
  flints 
  and 
  'eoliths,' 
  

   and 
  one 
  palaeolith 
  was 
  discovered 
  there 
  in 
  situ. 
  

  

  The 
  second 
  is 
  a 
  very 
  dark 
  bed, 
  composed 
  of 
  ironstone 
  and 
  sub- 
  

   angular 
  flints. 
  All 
  the 
  fossils 
  so 
  far 
  foi;nd 
  in 
  the 
  pit 
  have 
  been 
  

   discovered 
  in, 
  or 
  traced 
  to, 
  this 
  bed, 
  with 
  the 
  exception 
  of 
  the 
  

   remains 
  of 
  deer. 
  A 
  cast 
  of 
  a 
  Chalk 
  fossil, 
  Echinocorys 
  vulgaris, 
  

   from 
  the 
  Zone 
  of 
  llicraster 
  co7'-testudinarium,, 
  occurred 
  as 
  a 
  

   pebble. 
  

  

  The 
  third 
  bed 
  was 
  recognized 
  only 
  this 
  year, 
  and 
  consists 
  of 
  

   reconstructed 
  material 
  from 
  the 
  underlying 
  Wealden 
  rock 
  (Hastings 
  

   Series). 
  It 
  is 
  only 
  about 
  8 
  inches 
  thick, 
  and 
  contains 
  very 
  big 
  

   flints 
  (8 
  to 
  15 
  inches 
  long) 
  which 
  have 
  been 
  Httle 
  rolled, 
  and 
  are 
  

   not 
  striated. 
  They 
  are 
  satm-ated 
  with 
  iron, 
  and 
  have 
  undergone 
  

   considerable 
  chemical 
  change. 
  They 
  differ 
  very 
  markedly 
  in 
  

   appearance 
  from 
  the 
  smaller 
  flints 
  in 
  the 
  upper 
  strata. 
  No 
  imple- 
  

   ments, 
  ' 
  eoliths,' 
  or 
  fossil 
  bones 
  have 
  been 
  met 
  with 
  in 
  this 
  bed. 
  

  

  The 
  floor 
  of 
  the 
  gravel, 
  where 
  the 
  remains 
  of 
  Eoantliropus 
  were 
  

   discovered, 
  has 
  been 
  carefully 
  exposed, 
  and 
  many 
  irregularities 
  and 
  

   depressions 
  have 
  been 
  found 
  to 
  exist. 
  In 
  some 
  of 
  these 
  depressions 
  

   small 
  patches 
  of 
  the 
  dark 
  overlying 
  bed 
  remained, 
  and 
  new 
  sj^eci- 
  

   mens 
  were 
  discovered. 
  The 
  method 
  adopted 
  in 
  excavation 
  is 
  

   described. 
  

  

  The 
  finds 
  made 
  tliis 
  year 
  are 
  few 
  but 
  important, 
  and 
  include 
  the 
  

   nasal 
  bones, 
  and 
  a 
  canine 
  tooth 
  of 
  Eoanthroims 
  discovered 
  by 
  

   Father 
  P. 
  Teilhard 
  de 
  Chardin 
  ; 
  also 
  a 
  fragment 
  of 
  a 
  molar 
  of 
  

   Stegoclon 
  and 
  another 
  of 
  Rhinoceros 
  ; 
  an 
  incisor 
  and 
  broken 
  

   ramus 
  of 
  Beaver 
  (Castor 
  Jiber} 
  ; 
  a 
  worked 
  flint 
  from 
  the 
  dark 
  

   bed 
  ; 
  and 
  a 
  palaeolithic 
  implement 
  from 
  the 
  debris 
  in 
  the 
  pit. 
  It 
  

   will 
  be 
  noted 
  that 
  the 
  remains 
  are 
  those 
  of 
  a 
  land 
  fauna 
  only. 
  The 
  

   further 
  occurrence 
  of 
  bedded 
  flint-bearing 
  gravels 
  in 
  the 
  vicinity 
  of 
  

   the 
  pit 
  is 
  noted. 
  

  

  The 
  Authors' 
  former 
  conclusions, 
  as 
  to 
  the 
  Pliocene 
  forms 
  having 
  

   been 
  derived, 
  are 
  maintained.
