  It 
  has 
  hitherto, 
  with 
  a 
  few 
  disputed 
  exceptions, 
  been 
  generally 
  

   held 
  that, 
  in 
  this 
  country, 
  paleolithic 
  stone 
  implements 
  are 
  con- 
  

   fined 
  to 
  " 
  river-drifts 
  " 
  and 
  caves 
  of 
  the 
  so-called 
  Postglacial 
  a°-e, 
  

   in 
  which 
  they 
  occur 
  buried 
  at 
  greater 
  or 
  less 
  depths: 
  and 
  little 
  

   search 
  was 
  made 
  outside 
  the 
  drift-deposits, 
  or 
  the 
  valleys 
  to 
  which 
  

   such 
  deposits 
  are 
  confined. 
  It 
  is 
  true 
  that 
  a 
  few 
  specimens 
  had 
  

   been 
  found 
  at 
  various 
  heights 
  on 
  the 
  hills, 
  but 
  they 
  failed 
  to 
  attract 
  

   much 
  attention 
  or 
  to 
  suggest, 
  any 
  different 
  explanation. 
  In 
  1861 
  Dr. 
  

   John 
  Evans 
  * 
  found 
  a 
  large 
  pointed 
  implement 
  on 
  the 
  surface 
  of 
  a 
  

   ploughed 
  field 
  in 
  the 
  parish 
  of 
  Abbots 
  Langley, 
  and 
  at 
  a 
  height 
  of 
  

   160 
  feet 
  above 
  the 
  Colne. 
  Another 
  smaller 
  specimen 
  was 
  found 
  in 
  

   1861 
  by 
  llr. 
  TT. 
  Whitaker 
  on 
  the 
  surface 
  of 
  the 
  Chalk, 
  one 
  mile 
  

   east 
  of 
  Horton 
  Kirby, 
  and 
  about 
  200 
  feet 
  above 
  the 
  Darent 
  f. 
  In 
  

   1869, 
  in 
  searching 
  over 
  a 
  field 
  near 
  the 
  edge 
  of 
  the 
  Chalk-escarp- 
  

   ment 
  at 
  Currie 
  Farm, 
  Halstead, 
  Kent, 
  in 
  company 
  with 
  General 
  

   Pitt-Eivers, 
  Sir 
  J. 
  Lubbock, 
  and 
  myself, 
  Dr. 
  Evans 
  picked 
  up 
  a 
  

   rude 
  ovoid 
  specimen; 
  but 
  we 
  did 
  not 
  succeed 
  in 
  finding 
  any 
  

   more. 
  This 
  spot 
  is 
  nearly 
  600 
  (not 
  500) 
  feet 
  above 
  O.D. 
  From 
  

   time 
  to 
  time 
  a 
  few 
  similar 
  instances 
  have 
  been 
  recorded; 
  but 
  they 
  

   were 
  either 
  passed 
  by 
  as 
  chance 
  specimens, 
  possibly 
  dropped 
  and 
  lost, 
  

   or 
  were 
  in 
  some 
  way 
  supposed 
  to 
  be 
  connected 
  with 
  the 
  ordinary 
  

   river-valley 
  drifts 
  r. 
  

  

  But 
  the 
  remarkable 
  discoveries 
  of 
  palaeolithic 
  flint 
  implements 
  

   made 
  during 
  the 
  last 
  ten 
  years 
  by 
  Air. 
  Benjamin 
  Harrison, 
  of 
  

   Ightham, 
  in 
  the 
  neighbourhood 
  of 
  that 
  village, 
  and 
  lving 
  on 
  the 
  

   surface 
  of 
  the 
  ground, 
  at 
  all 
  levels 
  up 
  to 
  nearly 
  600 
  feet 
  above 
  the 
  

   sea§, 
  showed 
  that 
  the 
  subject 
  required 
  further 
  investigation. 
  I 
  

   was 
  otherwise 
  engaged 
  when 
  Air. 
  Harrison 
  first 
  called 
  mv 
  attention 
  

   to 
  his 
  discoveries 
  ; 
  and 
  though 
  from 
  year 
  to 
  year 
  I 
  have 
  paid 
  

   occasional 
  visits 
  with 
  him 
  to 
  the 
  different 
  sites 
  where 
  he 
  had 
  

   found 
  palaeolithic 
  implements, 
  it 
  was 
  not 
  until 
  this 
  last 
  summer 
  

   that 
  I 
  was 
  able 
  to 
  complete 
  my 
  survey 
  of 
  the 
  ground, 
  and 
  come 
  to

  Mr. 
  De 
  Barri 
  Crawshay, 
  of 
  Sevenoaks, 
  has 
  since 
  found 
  a 
  rude 
  ochreous 
  

   scraper 
  in 
  a 
  field 
  by 
  the 
  side 
  of 
  the

  § 
  Since 
  this 
  paper 
  -was 
  written, 
  Mr. 
  Harrison 
  informs 
  me 
  that 
  he 
  found 
  a 
  

   palaeolithic 
  implement, 
  very 
  like 
  the 
  Currie- 
  Wood 
  specimen, 
  on 
  the 
  summit 
  of 
  

   the 
  chalk-escarpment 
  above 
  Wrotham, 
  at 
  a 
  height 
  of 
  750 
  ft. 
  above 
  O.D. 
  I 
  

   have 
  not 
  yet 
  been 
  able 
  to 
  visit 
  the 
  spot.
