  Effect 
  of 
  

  

  later. 
  For 
  example, 
  in 
  the 
  experiments 
  where 
  the 
  rectal 
  temperatures 
  were 
  

   taken 
  half-way 
  through 
  the 
  walk, 
  the 
  rise 
  during 
  the 
  first 
  part 
  amounted 
  to 
  

   2° 
  or 
  3° 
  F., 
  whereas 
  it 
  was 
  only 
  further 
  increased 
  by 
  two 
  or 
  three-tenths 
  of 
  a 
  

   degree 
  after 
  the 
  repetition 
  of 
  the 
  effort. 
  The 
  chart 
  contains 
  a 
  graphic 
  

   representation 
  of 
  the 
  rectal 
  temperatures 
  during 
  a 
  two 
  hours' 
  walk 
  on 
  a 
  hot 
  

   day, 
  and 
  illustrates 
  the 
  above 
  statement. 
  

  

  In 
  the 
  hot 
  room 
  a 
  continued 
  rise 
  in 
  rectal 
  temperature 
  was 
  noted. 
  This 
  

   took 
  place 
  in 
  the 
  beginning 
  slowly 
  and 
  gradually, 
  but 
  the 
  rate 
  increased 
  

   with 
  time 
  and 
  with 
  increased 
  temperature, 
  thus 
  confirming 
  Haldane 
  (1905), 
  

   and 
  Harvey 
  Sutton's 
  (1908) 
  observations. 
  

  

  Alveolar 
  air. 
  — 
  The 
  percentage 
  of 
  carbon 
  dioxide 
  in 
  the 
  alveolar 
  air 
  has 
  

   been 
  estimated 
  by 
  a 
  number 
  of 
  observers 
  by 
  the 
  Haldane 
  and 
  Priestley 
  

   method, 
  and 
  their 
  results 
  on 
  individuals 
  at 
  rest 
  have 
  been 
  found 
  fairly 
  

   constant. 
  In 
  Table 
  IV 
  are 
  given 
  the 
  averages 
  of 
  58 
  observations 
  on 
  seven 
  

   subjects 
  at 
  rest, 
  whereas 
  Table 
  V 
  gives 
  for 
  comparison 
  averages, 
  maxima 
  

   and 
  minima, 
  obtained 
  by 
  other 
  workers 
  in 
  Europe. 
  The 
  figures 
  obtained 
  in 
  

   Townsville 
  are 
  lower 
  than 
  those 
  of 
  the 
  other 
  authors, 
  and 
  this 
  may 
  be 
  

   attributed 
  to 
  the 
  influence 
  of 
  the 
  higher 
  temperatures 
  of 
  the 
  atmosphere.
