  Sir 
  E. 
  Ray 
  Lankester. 
  On 
  some 
  

  

  A 
  lit. 
  

  

  dorsal 
  plane 
  or 
  platform, 
  D.P. 
  in 
  the 
  Oise 
  and 
  Burnham 
  specimens, 
  must 
  have 
  

   served 
  a 
  special 
  purpose. 
  I 
  suggest 
  that 
  it 
  would 
  facilitate 
  the 
  binding 
  of 
  the 
  

   implement 
  to 
  a 
  short 
  wooden 
  " 
  hefting 
  piece 
  " 
  which 
  (as 
  we 
  see 
  in 
  Neolithic 
  

  

  and 
  modern 
  Melanesian 
  examples) 
  was- 
  

   inserted 
  at 
  right 
  angles 
  into 
  a 
  stout 
  

   handle. 
  Of 
  course, 
  in 
  place 
  of 
  a 
  heft- 
  

   ing 
  piece, 
  the 
  ancient 
  men 
  may 
  have 
  

   employed 
  a 
  naturally 
  bifurcate 
  vege- 
  

   table 
  stem, 
  as 
  do 
  some 
  of 
  the 
  

   Melanesian 
  s 
  of 
  the 
  present 
  day.

  — 
  Anti-dorsal 
  aspect 
  of 
  the 
  Capitan- 
  

   Oise 
  specimen, 
  showing 
  the 
  median 
  

   position 
  taken 
  by 
  the 
  right 
  latero- 
  

   ventral 
  arrete 
  or 
  ridge, 
  rfo.,and 
  the 
  up- 
  

   throw 
  of 
  the 
  ventral 
  plane, 
  VP., 
  to 
  the 
  

   left 
  lateral 
  face 
  in 
  the 
  rostral 
  region, 
  

   whilst 
  the 
  broad 
  " 
  butt 
  " 
  or 
  " 
  stern 
  " 
  is 
  

   treated 
  merely 
  as 
  a 
  massive 
  base 
  to 
  the 
  

   large 
  dorsal 
  plane. 
  

  

  Section 
  IV. 
  — 
  The 
  Peake- 
  Sonning 
  

   Uncinate. 
  

  

  The 
  specimen 
  drawn 
  in 
  figs. 
  13 
  and 
  14 
  

   was 
  obtained 
  in 
  the 
  gravel 
  at 
  Sonning 
  

   (on 
  Thames) 
  by 
  Dr. 
  A. 
  E. 
  Peake, 
  of 
  Bur- 
  

   ford, 
  and 
  has 
  been 
  kindly 
  lent 
  by 
  him 
  to 
  

   me 
  for 
  description. 
  It 
  is 
  a 
  large 
  example 
  

   of 
  a 
  form 
  which 
  may 
  be 
  considered 
  as 
  

   a 
  derivative 
  of 
  the 
  last 
  two 
  described, 
  

   in 
  which 
  not 
  only 
  the 
  " 
  ventral 
  plane," 
  

   but 
  also 
  the 
  dorsal 
  platform 
  or 
  plane 
  

   has 
  been 
  abandoned 
  as 
  an 
  element 
  in 
  

   the 
  modelling 
  of 
  the 
  completed 
  imple- 
  

   ment. 
  It 
  is 
  simply 
  a 
  " 
  rostro-carinate," 
  

   reduced 
  to 
  a 
  more 
  or 
  less 
  " 
  uncinate 
  " 
  

   rostrum, 
  and 
  a 
  simple 
  flaked 
  " 
  body 
  " 
  

   suitable 
  for 
  the 
  hand-grip. 
  Smaller 
  

   flints, 
  having 
  the 
  same 
  general 
  shape, 
  

   are 
  known, 
  but 
  the 
  evidence 
  of 
  human 
  

   workmanship 
  in 
  this 
  larger 
  specimen 
  

   is 
  more 
  convincing 
  than 
  in 
  others 
  which 
  

   probably 
  are 
  to 
  be 
  interpreted 
  also 
  as 
  

   human 
  productions. 
  The 
  series 
  of 
  

   parallel 
  flakings 
  on 
  the 
  left 
  face 
  of 
  the 
  

   Sonning 
  specimen 
  (fig. 
  13) 
  are 
  clearly 
  

  

  of 
  human 
  origin. 
  A 
  large 
  area 
  of 
  

   original 
  cortex 
  (x 
  and 
  y 
  in 
  figs. 
  13 
  and 
  14) 
  is 
  retained 
  and 
  forms 
  a 
  sort 
  of 
  

   collar, 
  marking 
  off 
  the 
  " 
  rostrum 
  " 
  from 
  the 
  rest 
  of 
  the 
  flint. 
  In 
  the 
  explana- 
  

   tion 
  of 
  figs. 
  13 
  and 
  14 
  I 
  have 
  suggested 
  the 
  possible 
  identification 
  of 
  certain
