  THE 
  TABLE. 
  

  

  No. 
  1. 
  These 
  specimens 
  were 
  divided 
  into 
  four 
  lots 
  and 
  put 
  into 
  

   small 
  covered 
  tin 
  pill-boxes 
  lined 
  with 
  moist 
  blotting 
  paper, 
  with 
  a 
  

   pieice 
  of 
  green 
  corn 
  leaf 
  in 
  each. 
  The 
  blotting 
  paper 
  was 
  moist 
  at 
  

   the 
  end 
  of 
  the 
  experiment, 
  showing 
  that 
  the 
  air 
  had 
  been 
  completely- 
  

   saturated.

  Most 
  of 
  the 
  specimens 
  were 
  feeding 
  on 
  the 
  enclosed 
  corn 
  

   leaf 
  at 
  the 
  termination 
  of 
  the 
  experiment.

  The 
  temperature 
  was 
  gradually 
  raised 
  during 
  this 
  experi- 
  

   ment 
  from 
  114° 
  to 
  126 
  ^ 
  The 
  fact 
  that 
  the 
  adults 
  began 
  to 
  succumb 
  

   to 
  the 
  heat 
  before 
  the 
  young, 
  suggests 
  that 
  they 
  were 
  spent 
  insects, 
  

   since 
  in 
  the 
  field 
  the 
  young 
  are 
  much 
  more 
  sensitive 
  to 
  heat 
  than 
  the 
  

   old.
