  I 
  do 
  not 
  regard 
  the 
  differences 
  as 
  showing 
  any 
  distinct 
  

   alteration 
  of 
  emotivity 
  under 
  the 
  influence 
  of 
  pilocarpine. 
  The 
  effect 
  on 
  

   the

  upon 
  salivary 
  secretion 
  was 
  evident

  60

  of

  were 
  secreted

  The 
  negative 
  result 
  observed 
  after 
  pilocarpine 
  is 
  in 
  agreement 
  with 
  

   observations 
  I 
  have 
  made 
  in 
  cases 
  of 
  shell-shock 
  where 
  perspiration 
  has 
  been 
  

   excessive 
  without 
  any 
  corresponding 
  augmentation 
  of 
  conductivity 
  and 
  an 
  

   emotive 
  reaction 
  greater 
  than 
  normal. 
  The 
  condition 
  is 
  illustrated 
  in 
  the 
  

   following 
  case 
  : 
  — 
  

  

  Sergeant 
  B 
  , 
  D.C.M., 
  under 
  the 
  care 
  of 
  Colonel 
  Mott 
  and 
  Captain 
  Golla

  the 
  Maudsley 
  Hospital. 
  Shell-shock.

  perspiration
