  Pilocarpine, 
  by 
  reason 
  of 
  its 
  sudorific 
  action, 
  might 
  be 
  expected 
  to 
  produce 
  

   an 
  unmistakable 
  augmentation 
  of 
  conductivity. 
  In 
  two 
  experiments, 
  made 
  

   ad 
  hoc, 
  augmentation 
  of 
  conductivity 
  has 
  been 
  well 
  marked, 
  but 
  the 
  emotive 
  

   reaction 
  was 
  not 
  appreciably 
  altered.
