  the 
  Brain 
  of 
  Monkeys. 
  

  

  tion 
  o£ 
  two 
  centres 
  which 
  individually 
  are 
  capable 
  of 
  differentiation. 
  

   This 
  is 
  particularly 
  liable 
  to 
  occur 
  if 
  the 
  currents 
  are 
  too 
  strong. 
  The 
  

   areas 
  drawn 
  on 
  the 
  woodcuts 
  are 
  therefore 
  more 
  or 
  less 
  indefinite 
  as 
  to 
  

   their 
  boundaries. 
  Their 
  centres 
  indicate 
  more 
  precisely 
  the 
  points 
  of 
  

   exact 
  localization. 
  

  

  Besides 
  describing 
  the 
  results 
  of 
  stimulation 
  by 
  reference 
  to 
  the 
  figures, 
  

   1 
  have 
  indicated 
  the 
  position 
  of 
  the 
  electrodes, 
  as 
  far 
  as 
  possible, 
  in 
  rela- 
  

   tion 
  to 
  the 
  individual 
  convolutions, 
  so 
  that 
  comparison 
  may 
  be 
  made 
  with 
  

   those 
  of 
  the 
  human 
  brain. 
  

  

  For 
  this 
  reason 
  the 
  results 
  are 
  classified, 
  and 
  not 
  related 
  in 
  the 
  order 
  

   in 
  which 
  they 
  were 
  obtained 
  during 
  the 
  course 
  of 
  experiment.
