  origin 
  of 
  these 
  implements, 
  that 
  although 
  found 
  on 
  the 
  surface-soil, 
  

   and 
  associated 
  with 
  many 
  comparatively 
  unaltered 
  Neolithic 
  flints, 
  

   a 
  considerable 
  proportion 
  of 
  these 
  Paleeolithic 
  implements 
  are 
  studded 
  

   on 
  one 
  side 
  with 
  small 
  dark-brown 
  concretionary 
  incrustations 
  of 
  

   iron 
  peroxide 
  and 
  sand 
  (see 
  PL 
  XI. 
  fig. 
  6). 
  Many 
  of 
  the 
  brown 
  flints 
  

   have 
  also 
  the 
  same 
  sort 
  of 
  incrustation. 
  From 
  this 
  we 
  may 
  infer 
  

   that 
  both 
  the 
  flint 
  implements 
  and 
  the 
  flints 
  have 
  at 
  one 
  time 
  been 
  

   imbedded 
  in 
  a 
  sandy, 
  ferruginous 
  matrix, 
  just 
  as 
  the 
  film 
  of 
  calcite 
  on 
  

   the 
  under 
  side 
  of 
  some 
  of 
  the 
  St. 
  Acheul 
  specimens 
  shows 
  them 
  to 
  

   come 
  from 
  one 
  of 
  the 
  seams 
  of 
  calcareous 
  sand 
  or 
  chalky 
  gravel 
  

   common 
  in 
  the 
  drift 
  there, 
  or 
  as 
  the 
  ferruginous 
  concretions 
  on 
  the 
  

   Dunks 
  Green 
  specimens 
  indicate 
  their 
  origin 
  in 
  that 
  drift 
  f 
  . 
  

  

  The 
  Ash 
  specimens 
  are 
  not 
  scattered 
  indiscriminately 
  over 
  the 
  

   chalk 
  plateau, 
  but 
  seem 
  associated 
  with 
  the 
  worn 
  brown 
  flints 
  which 
  

   here 
  lie 
  on 
  the 
  few 
  acres 
  of 
  Tertiary 
  sands 
  and 
  shingle 
  immediately 
  

   north 
  of 
  the 
  church, 
  or 
  at 
  South 
  Ash 
  on 
  the 
  " 
  red 
  clay 
  with 
  

   flints," 
  and 
  would 
  appear 
  for 
  the 
  reasons 
  aforesaid 
  to 
  belong 
  to 
  an 
  old 
  

   drift-deposit 
  of 
  which 
  only 
  the 
  remnants 
  now 
  remain 
  on 
  the 
  high 
  

   summits 
  of 
  the 
  chalk 
  plain, 
  the 
  main 
  body 
  having 
  been 
  removed 
  by 
  

   denudation. 
  Beyond 
  these 
  indications 
  of 
  its 
  former 
  position 
  we 
  

   have 
  yet 
  failed 
  to 
  detect 
  the 
  original 
  beds 
  ; 
  possibly 
  they 
  no 
  longer 
  

   exist 
  in 
  situ. 
  

  

  Precisely 
  similar 
  specimens 
  to 
  the 
  number 
  of 
  twelve 
  or 
  more 
  have 
  

   recently 
  been 
  found 
  by 
  Mr. 
  Harrison 
  between 
  Romney 
  Street 
  and 
  

   Bower 
  Farm, 
  near 
  Eynsford, 
  3-J- 
  miles 
  west 
  from 
  Ash, 
  and 
  520 
  ft. 
  

   above 
  O.D. 
  They 
  are 
  there 
  also 
  associated 
  with 
  the 
  brown-stained, 
  

   subangular, 
  and 
  rolled 
  flints, 
  which 
  there 
  lie 
  on 
  a 
  surface 
  of 
  red- 
  

   clay-with-flints 
  : 
  they 
  exhibit 
  the 
  same 
  ferruginous 
  incrustation, 
  and 
  

   are 
  equally 
  rude 
  and 
  misshapen 
  in 
  form 
  as 
  those 
  of 
  Ash. 
  This 
  

   locality 
  possesses 
  the 
  additional 
  interest 
  that 
  it 
  overlooks 
  the 
  Darent 
  

   valley 
  with 
  its 
  Postglacial 
  river-drift, 
  and 
  is 
  nearly 
  400 
  ft. 
  above 
  

   the 
  level 
  of 
  the

  Eynsford,
