   Introductory. 
  

  

  The 
  present 
  communication 
  is 
  in 
  continuation 
  of 
  that 
  made 
  to 
  the 
  Royal 
  

   Society 
  on 
  November 
  8 
  of 
  last 
  year. 
  

  

  At 
  an 
  early 
  stage 
  of 
  the 
  enquiry, 
  I 
  noticed 
  that 
  the 
  emotive 
  effect 
  varied 
  

   considerably 
  in 
  magnitude 
  upon 
  the 
  same 
  subject 
  (G. 
  de 
  D.) 
  according 
  as 
  she 
  

   was 
  rested 
  or 
  fatigued, 
  and 
  that 
  it 
  was 
  usually 
  larger 
  during 
  the 
  day 
  than 
  

   late 
  in 
  the 
  evening 
  ; 
  also 
  that 
  the 
  electrical 
  resistance 
  was 
  higher 
  during 
  the 
  

   evening 
  than 
  during 
  the 
  day. 
  

  

  I 
  also 
  noticed 
  on 
  my 
  own 
  hand 
  that 
  the 
  electrical 
  resistance 
  was 
  much 
  

   higher 
  during 
  the 
  night 
  than 
  during 
  the 
  day, 
  e.g., 
  200,000 
  ohms 
  at 
  2 
  A.M. 
  as 
  

   compared 
  with 
  30,000 
  ohms 
  at 
  2 
  p.m., 
  and 
  that 
  the 
  electrical 
  effects 
  on 
  the 
  

   palm 
  that 
  accompany 
  natural 
  physiological 
  discbarges 
  such 
  as 
  coughing, 
  

   sneezing, 
  and 
  shouting, 
  as 
  well 
  as 
  the 
  natural 
  responses 
  to 
  a 
  pin 
  prick 
  or 
  

   burn, 
  were 
  remarkably 
  small. 
  (At 
  such 
  time 
  of 
  depression, 
  however, 
  the 
  

   electrical 
  effect 
  of 
  yawning 
  continued 
  to 
  be 
  exceptionally 
  distinct.)
