  PROCEEDINGS 
  OF 
  THE 
  FOURTH 
  ENTOMOLOGICAL 
  MEETING 
  

  

  Mr. 
  Ballard. 
  In 
  this 
  matter 
  of 
  automatic 
  response 
  to 
  fixed 
  stimuli, 
  I 
  once 
  noticed 
  

  

  a 
  potter 
  wasp 
  building 
  in 
  my 
  bedroom. 
  It 
  gave 
  up 
  bringing 
  in 
  mud, 
  

   and 
  took 
  to 
  using 
  the 
  soap, 
  but 
  did 
  not 
  complete 
  the 
  cell 
  with 
  this, 
  

   but 
  returned 
  to 
  using 
  mud. 
  Why, 
  I 
  cannot 
  say. 
  The 
  soap 
  was 
  regu- 
  

   larly 
  in 
  use. 
  and 
  its 
  moisture 
  content 
  presumably, 
  therefore, 
  constant.
