  Brain 
  of 
  Monkeys. 
  

  

  of 
  epileptic 
  fit, 
  beginning 
  in 
  the 
  left 
  angle 
  of 
  the 
  mouth/next 
  pro- 
  

   ceeding 
  to 
  the 
  left 
  arm 
  and 
  hand, 
  and, 
  lastly, 
  affecting 
  the 
  left 
  

   leg 
  and 
  tail. 
  The 
  spasms 
  next 
  attacked 
  the 
  right 
  angle 
  of 
  the 
  

   month, 
  the 
  right 
  arm, 
  and 
  the 
  right 
  leg 
  in 
  succession. 
  

  

  The 
  fit 
  lasted 
  several 
  minutes. 
  The 
  pupils 
  were 
  not 
  dilated, 
  

   nor 
  did 
  the 
  animal 
  apparently 
  lose 
  consciousness 
  completely.

  XIII. 
  Contraction 
  of 
  left 
  angle 
  of 
  mouth. 
  

  

  These 
  results 
  indicate 
  that 
  this 
  is 
  a 
  centre 
  for 
  the 
  muscles 
  acting 
  on 
  

   the 
  angle 
  of 
  the 
  mouth, 
  and 
  apparently 
  of 
  the 
  zygomatics.

  Lower 
  down 
  in 
  the 
  same 
  ascending 
  frontal 
  

  

  convolution. 
  

  

  I. 
  The 
  action 
  is 
  similar 
  to 
  that 
  resulting 
  from 
  stimulation 
  of 
  the 
  former 
  

  

  centre, 
  but 
  seems 
  especially 
  to 
  cause 
  elevation 
  of 
  the 
  lip 
  and 
  ala 
  

   of 
  the 
  nose 
  on 
  the 
  right 
  side. 
  

  

  II. 
  At 
  the 
  anterior 
  part 
  of 
  the 
  circle 
  the 
  left 
  angle 
  of 
  the 
  mouth 
  is 
  

  

  drawn 
  upwards 
  and 
  backwards 
  (zygomatic!). 
  At 
  the 
  posterior 
  and 
  

   lower 
  margin 
  of 
  the 
  circle 
  the 
  action 
  is 
  combined 
  with 
  that 
  of 
  the 
  

   depressor 
  anguli 
  oris, 
  so 
  as 
  to 
  expose 
  the 
  canine 
  teeth.

  V. 
  Elevation 
  of 
  the 
  upper 
  lip 
  (right 
  side) 
  and 
  right 
  side 
  of 
  nose. 
  

  

  Stimulation 
  was 
  followed 
  by 
  prolonged 
  choreic-like 
  twitching 
  

   of 
  the 
  right 
  angle 
  of 
  the 
  mouth 
  and 
  ala 
  of 
  nose. 
  

  

  VI.

  VII. 
  Elevation 
  of 
  right 
  side 
  of 
  upper 
  lip 
  and 
  ala 
  of 
  nose, 
  along 
  with 
  

   depression 
  of 
  the 
  lower 
  lip. 
  

  

  YIII. 
  Combined 
  action 
  of 
  the 
  elevator 
  of 
  the 
  upper 
  lip 
  and 
  ala 
  of 
  the 
  

   nose 
  and 
  of 
  the 
  depressor 
  anguli 
  iris, 
  so 
  as 
  to 
  expose 
  the 
  canine 
  

   teeth. 
  

  

  IX. 
  Elevation 
  of 
  the 
  upper 
  lip 
  and 
  depression 
  of 
  the 
  lower, 
  so 
  as 
  to 
  

   cause 
  divergence 
  of 
  the 
  lips 
  and 
  expose 
  the 
  teeth. 
  

  

  X. 
  A 
  similar 
  result, 
  but 
  not 
  so 
  distinct, 
  as 
  the 
  occurrence 
  of 
  choreic 
  

  

  spasms 
  interfered 
  with 
  successful 
  observation. 
  

  

  XI. 
  Results 
  as 
  in 
  IX. 
  

  

  XII. 
  Not 
  explored. 
  

  

  XIII. 
  At 
  lower 
  part 
  of 
  circle 
  the 
  depressor 
  anguli 
  oris 
  is 
  thrown 
  into 
  

   action 
  ; 
  at 
  the 
  upper 
  part 
  the 
  angle 
  of 
  the 
  mouth 
  is 
  elevated. 
  

  

  These 
  results 
  are 
  sufficiently 
  uniform 
  to 
  indicate 
  a 
  centre 
  for 
  the 
  facial 
  

   muscles 
  concerned 
  in 
  the 
  production 
  of 
  that 
  expressional 
  action 
  so 
  fre-
