  Emotive

  the 
  Air-raid 
  of 
  May 
  19-20. 
  

   M. 
  First 
  warning

  maroons. 
  

  

  G. 
  Commencement 
  of 
  gunfire,

  H. 
  Aeroplane 
  hum

  audible. 
  

  

  S. 
  Second 
  warning

  (c) 
  Electrode 
  A 
  was 
  transferred 
  to 
  the 
  forearm, 
  B 
  being 
  kept 
  in 
  the 
  

   mouth. 
  The 
  deflection 
  steadily 
  increased 
  to 
  about 
  twice 
  its 
  original 
  value. 
  

  

  Second 
  Experiment. 
  — 
  A 
  pair 
  of 
  electrodes 
  was 
  fixed 
  to 
  the 
  left 
  hand 
  of 
  the 
  

   President 
  (Sir 
  J. 
  J. 
  Thomson), 
  placed 
  in 
  the 
  4th 
  arm 
  of 
  a 
  Wheatstone 
  

   bridge 
  in 
  series, 
  with 
  a 
  potentiometer 
  delivering 
  1/5 
  Leclanche" 
  for 
  calibra- 
  

   tion. 
  Main 
  circuit 
  supplied 
  by 
  two 
  Leclanehe" 
  cells. 
  Balance 
  having 
  been 
  

   established, 
  Dr. 
  Waller 
  proceeded 
  to 
  stand 
  behind 
  the 
  President's 
  chair, 
  and 
  

   a 
  deflection 
  of 
  approximately 
  60 
  cm. 
  of 
  scale 
  occurred, 
  representing 
  the 
  

   emotive 
  response 
  of 
  the 
  President 
  to 
  Dr. 
  Waller's 
  presence 
  behind 
  him. 
  The 
  

   electromotive 
  value 
  of 
  the 
  deflection 
  was 
  approximately 
  05 
  volt 
  ; 
  expressed 
  

   in 
  terms 
  of 
  a 
  reciprocal 
  megohm, 
  it 
  had 
  a 
  conductivity 
  value 
  of 
  +67, 
  i.e., 
  

   an 
  increase 
  of 
  20 
  per 
  cent, 
  of 
  the 
  original 
  conductivity 
  (30 
  7 
  or 
  33,000 
  «■>).]
