  action 
  (vide 
  supra, 
  p. 
  36). 
  Nevertheless, 
  the 
  association 
  between 
  various 
  

   emotive 
  manifestations 
  is 
  such 
  that 
  it 
  would 
  be 
  hazardous 
  to 
  assert 
  that 
  they 
  

   are 
  absolutely 
  independent 
  of 
  each 
  other 
  ; 
  perhaps 
  the 
  relation 
  between 
  

   the 
  electrical 
  and 
  the 
  secretory 
  change 
  can 
  be 
  intelligibly 
  conveyed 
  by 
  

   saying 
  that 
  whereas 
  the 
  electrical 
  is 
  not 
  a 
  consequence 
  of 
  the 
  secretory 
  

   phenomenon, 
  i.e., 
  in 
  series 
  with 
  it. 
  both 
  phenomena 
  are 
  consequences 
  of 
  

   metabolic 
  activity, 
  i.e., 
  in 
  parallel 
  with 
  each 
  other. 
  Even 
  this 
  limited 
  degree 
  

   of 
  association 
  requires 
  the 
  further 
  qualification 
  that 
  our 
  parallel 
  move- 
  

   ments 
  may 
  be 
  in 
  opposed 
  directions, 
  i.e., 
  an 
  increased 
  emotive 
  deflection 
  

   may 
  be 
  accompanied 
  by 
  decreased 
  secretion. 
  Fear 
  dries 
  the 
  mouth, 
  and 
  the 
  

   following 
  experiment 
  appears 
  to 
  show 
  that 
  emotion 
  can 
  dry 
  the 
  skin, 
  although, 
  

   as 
  is 
  well 
  known, 
  the 
  usual 
  effect 
  of 
  emotion 
  is 
  increased 
  perspiration. 
  

   Grief 
  excites 
  tears, 
  but 
  extreme 
  grief 
  may 
  be 
  tearless. 
  

  

  Experiment 
  7. 
  — 
  Miss 
  G. 
  de 
  D., 
  a 
  Belgian 
  lady, 
  who 
  is 
  familiar 
  with 
  these 
  

   experiments, 
  and 
  highly 
  skilled 
  in 
  the 
  laboratory 
  methods 
  of 
  carrying 
  them 
  

   out, 
  prepared 
  apparatus 
  to 
  take 
  a 
  40-minute 
  photographic 
  record 
  of 
  her 
  

   own 
  emotive 
  state 
  by 
  means 
  of 
  electrodes 
  on 
  back 
  and 
  palm 
  of 
  one 
  hand 
  and 
  

   measured 
  the 
  insensible 
  perspiration 
  of 
  the 
  other 
  palm 
  by 
  means 
  of 
  an 
  

   inverted 
  glass 
  Ca 
  CI2 
  capsule 
  strapped 
  to 
  the 
  hand 
  and 
  giving 
  by 
  its 
  increase 
  

   of 
  weight 
  a 
  measure 
  of 
  insensible 
  perspiration. 
  She 
  set 
  herself 
  the 
  task 
  of 
  

   remaining 
  emotionless 
  during 
  the 
  first 
  20 
  minutes, 
  and 
  emotionally 
  unhappy 
  

   during 
  the 
  next 
  20 
  minutes. 
  At 
  the 
  end 
  of 
  these 
  two 
  periods 
  the 
  capsule 
  

   was 
  weighed 
  showing 
  a 
  smaller 
  increment 
  of 
  weight 
  during 
  the 
  emotional 
  

   than 
  during 
  the 
  emotionless 
  period, 
  and 
  the 
  developed 
  photogram 
  proved 
  

   conclusively 
  that 
  these 
  states 
  of 
  mind 
  had 
  been 
  successfully 
  maintained. 
  

   (The 
  psychological 
  interest 
  of 
  this 
  fact 
  is 
  obvious, 
  it 
  implies 
  considerable 
  

   power 
  of 
  self-control, 
  of 
  which 
  subjects 
  are 
  more 
  or 
  less 
  capable; 
  the 
  

   emotional 
  state 
  in 
  G. 
  de 
  D. 
  was 
  secured 
  by 
  voluntary 
  recollection 
  of 
  air-
