  PRIMEVAL 
  MAN. 
  

  

  The 
  difference 
  between 
  the 
  hand 
  of 
  a 
  monkey 
  

   and 
  the 
  hand 
  of 
  a 
  man 
  may 
  seem 
  small 
  when 
  

   they 
  are 
  both 
  placed 
  on 
  the 
  dissecting 
  table 
  ; 
  

   but 
  in 
  that 
  difference, 
  whatever 
  it 
  may 
  be, 
  lies 
  

   the 
  whole 
  difference 
  between 
  an 
  organ 
  limited 
  

   to 
  the 
  climbing 
  of 
  trees 
  or 
  the 
  plucking 
  of 
  

   fruit, 
  and 
  an 
  organ 
  which 
  is 
  so 
  correlated 
  with 
  

   man's 
  inventive 
  genius 
  that 
  by 
  its 
  aid 
  the 
  Earth 
  

   is 
  weighed, 
  and 
  the 
  distance 
  of 
  the 
  Sun 
  is 
  

   measured. 
  In 
  like 
  manner 
  let 
  us 
  assume 
  it 
  

   to 
  be 
  true 
  that 
  the 
  difference 
  between 
  the 
  

   brain 
  of 
  Man 
  and 
  the 
  brain 
  of 
  the 
  Gorilla 
  

   may 
  be 
  reduced 
  to 
  a 
  difference 
  of 
  volume, 
  

   to 
  that 
  visible 
  difference 
  alone, 
  and 
  even 
  as 
  

   regards 
  volume 
  to 
  a 
  difference 
  in 
  quantity 
  

   comparatively 
  small. 
  " 
  Cranial 
  capacity 
  " 
  is 
  

   measured 
  by 
  the 
  cubic 
  inches 
  of 
  space 
  which
