  of 
  the 
  rnouth, 
  with 
  some 
  movements 
  of 
  the 
  cheek-pouches 
  and 
  

  

  tongue, 
  were 
  observed. 
  

   X. 
  In 
  this 
  case 
  stimulation 
  of 
  the 
  corresponding 
  region 
  caused 
  some 
  

  

  indistinct 
  movements 
  of 
  the 
  mouth 
  and 
  lips. 
  

   XIII. 
  In 
  this 
  case 
  there 
  were 
  some 
  movements 
  of 
  the 
  jaws 
  ; 
  not 
  of 
  

  

  any 
  decided 
  character. 
  

  

  These 
  are 
  all 
  the 
  facts 
  I 
  have 
  been 
  able 
  to 
  gather 
  from 
  experimentation 
  

   on 
  this 
  region, 
  which 
  is 
  attended 
  with 
  some 
  difficulty.

  This 
  region 
  was 
  reached 
  and 
  stimulated 
  in 
  the 
  following 
  cases 
  with 
  these 
  

   results 
  : 
  — 
  

  

  VIII. 
  Spasmodic 
  contraction 
  of 
  the 
  left 
  lip 
  and 
  ala 
  of 
  the 
  nose. 
  The 
  

   result 
  was 
  a 
  sort 
  of 
  torsion 
  or 
  closure 
  of 
  the 
  nostril, 
  as 
  when 
  an 
  

   irritant 
  is 
  applied 
  to 
  it. 
  The 
  action 
  was 
  on 
  the 
  same 
  side, 
  not 
  

   crossed, 
  as 
  usual. 
  

  

  IX. 
  Spasmodic 
  torsion 
  of 
  the 
  right 
  lip 
  and 
  nostril, 
  also 
  on 
  same 
  side 
  

   as 
  stimulation. 
  

  

  X. 
  Similar 
  results, 
  viz. 
  an 
  elevation 
  of 
  the 
  right 
  nostril 
  and 
  lip, 
  so 
  as 
  

  

  to 
  cause 
  partial 
  closure. 
  In 
  this 
  case 
  the 
  phenomenon 
  was 
  ob- 
  

   served 
  on 
  both 
  sides, 
  the 
  right 
  more 
  especially, 
  however. 
  

   XIII. 
  Torsion 
  of 
  the 
  right 
  lip 
  and 
  nostril, 
  as 
  before. 
  

  

  In 
  all 
  these 
  cases 
  the 
  phenomena 
  were 
  exactly 
  alike.
