  Experiment 
  4, 
  December 
  12. 
  — 
  At 
  2.30 
  p.m. 
  subject 
  injected 
  as 
  before 
  

   (1/200 
  grain). 
  At 
  2.45 
  p.m. 
  subject 
  put 
  into 
  the 
  circuits. 
  The 
  resistance 
  of 
  

   the 
  atropinised 
  hand 
  was 
  low 
  at 
  first, 
  but 
  as 
  the 
  atropine 
  began 
  to 
  take 
  

   effect 
  it 
  became 
  higher 
  and 
  higher. 
  Eecord 
  taken 
  at 
  3.15 
  p.m. 
  Various 
  

   stimuli 
  were 
  used. 
  The 
  results 
  were 
  negative 
  as 
  in 
  Experiment 
  3, 
  i.e., 
  

   emotive 
  responses 
  persisted 
  in 
  both 
  palms. 
  

  

  Experiment 
  5, 
  January 
  3. 
  — 
  At 
  2.0 
  p.m. 
  the 
  subject 
  was 
  injected 
  in 
  the 
  left 
  

   palm 
  with 
  l 
  - 
  5 
  mgrm. 
  atropine 
  sulphate. 
  At 
  2.30 
  p.m. 
  the 
  subject 
  was 
  put 
  

   into 
  the 
  circuits, 
  various 
  stimuli 
  were 
  used. 
  No 
  appreciable 
  difference 
  was 
  

   noticed 
  between 
  the 
  response 
  of 
  the 
  atropinised 
  and 
  that 
  of 
  the 
  normal 
  hand. 
  

  

  Experiment 
  6. 
  — 
  To 
  make 
  quite 
  sure 
  of 
  these 
  results, 
  Miss 
  De 
  Decker 
  very 
  

   kindly 
  allowed 
  herself 
  to 
  be 
  injected 
  with 
  2 
  mgrm. 
  (0 
  - 
  00195 
  grm.) 
  of 
  atropine 
  

   sulphate. 
  She 
  was 
  then 
  put 
  into 
  the 
  circuits, 
  and 
  the 
  results 
  were 
  observed 
  

   by 
  two 
  witnesses. 
  On 
  applying 
  a 
  stimulus, 
  equal 
  responses 
  were 
  obtained 
  

   from 
  both 
  hands. 
  The 
  drug 
  took 
  full 
  effect, 
  great 
  dryness, 
  parching 
  of 
  the 
  

   throat, 
  and 
  a 
  headache 
  resulted. 
  (Details 
  of 
  this 
  experiment 
  are 
  given 
  by 
  

   Dr. 
  Waller, 
  p. 
  38.) 
  

  

  Conclusions. 
  

  

  I 
  cannot 
  feel 
  that 
  any 
  very 
  definite 
  conclusions 
  can 
  be 
  drawn 
  from 
  these 
  

   experiments. 
  For 
  instance, 
  the 
  discrepancy 
  between 
  these 
  results 
  and 
  those 
  

   of 
  Dr. 
  Leva 
  may 
  be 
  due, 
  it 
  seems 
  to 
  me, 
  to 
  one 
  of 
  two 
  reasons. 
  

  

  (1) 
  It 
  may 
  be 
  due 
  to 
  the 
  different 
  effect 
  of 
  atropine 
  on 
  different 
  people 
  — 
  

   a 
  fact 
  well 
  known 
  to 
  doctors 
  ; 
  this 
  could 
  only 
  be 
  decided 
  by 
  carrying 
  out 
  the 
  

   same 
  experiment 
  on 
  a 
  great 
  number 
  of 
  subjects. 
  

  

  (2) 
  It 
  may 
  be 
  due 
  to 
  technical 
  errors. 
  Dr. 
  Leva 
  does 
  not 
  give 
  any 
  details 
  

   of 
  his 
  technique, 
  nor 
  does 
  he 
  state 
  whether 
  or 
  not 
  he 
  noted 
  the 
  resistance 
  of 
  

   his 
  subjects. 
  

  

  As 
  seen 
  in 
  Experiment 
  2, 
  if 
  the 
  resistance 
  is 
  very 
  high 
  the 
  change 
  due 
  

   to 
  the 
  stimulus 
  may 
  not 
  be 
  seen 
  on 
  a 
  rnediumly 
  sensitive 
  instrument 
  — 
  

   there 
  should 
  be 
  some 
  means 
  of 
  altering 
  the 
  sensitivity 
  of 
  the 
  galvanometers 
  

   according 
  to 
  the 
  resistances 
  so 
  as 
  to 
  get 
  all 
  results 
  comparable 
  to 
  one 
  

   another. 
  

  

  Atropine, 
  in 
  stopping 
  the 
  secretions, 
  makes 
  the 
  resistance 
  higher, 
  so 
  that 
  

   it 
  is 
  quite 
  possible 
  that 
  in 
  Dr. 
  Leva's 
  experiments 
  the 
  response 
  really 
  took 
  

   place, 
  but 
  was 
  not 
  detected 
  by 
  the 
  galvanometer. 
  

  

  In 
  these 
  experiments 
  at 
  any 
  rate 
  atropine 
  had 
  no 
  effect 
  on 
  the 
  emotive 
  

   response. 
  

  

  My 
  best 
  thanks 
  are 
  due 
  to 
  Dr. 
  Waller 
  for 
  all 
  his 
  help.
