  Seventh 
  Annual 
  Repokt 
  of 
  the 
  

  

  individual 
  variations 
  in 
  the 
  effect 
  of 
  ordinary 
  conditions 
  npon 
  the 
  

   temperature, 
  such 
  as 
  food, 
  excitement, 
  and 
  temperature 
  of 
  the 
  

   air. 
  A 
  hot 
  spell 
  (temperature 
  90° 
  F.) 
  caused 
  a 
  rise 
  of 
  2°, 
  and 
  in 
  

   some 
  cases 
  4°. 
  The 
  average 
  temperature 
  of 
  the 
  animals 
  in 
  the 
  

   three 
  herds 
  tested 
  was 
  102.5°, 
  102. 
  6^ 
  and 
  101° 
  F. 
  respectively. 
  

   In 
  a 
  well-kept 
  government 
  herd 
  that 
  was 
  tested 
  with 
  tuber- 
  

   culin 
  the 
  temperature 
  of 
  part 
  of 
  the 
  animals 
  was 
  taken 
  hourly 
  

   for 
  twenty-four 
  hours 
  and 
  a 
  part 
  of 
  them 
  for 
  sixteen 
  hours 
  (7 
  

   A. 
  M. 
  to 
  11 
  P. 
  M.) 
  preceding 
  the 
  injection. 
  An 
  examination 
  of 
  

   the 
  records^^ 
  shows 
  the 
  average 
  daily 
  variation 
  of 
  twenty 
  animals 
  

   in 
  which 
  the 
  temperature 
  was 
  taken 
  for 
  twenty-four 
  hours 
  to 
  be 
  

   2.31° 
  F. 
  The 
  maximum 
  individual 
  variation 
  in 
  a 
  single 
  day 
  was 
  

   4.3° 
  F., 
  the 
  minimum 
  0.5° 
  F. 
  In 
  twenty-five 
  others, 
  where 
  the 
  

   temperature 
  was 
  taken 
  for 
  sixteen 
  hours, 
  the 
  average 
  variation 
  

   was 
  1.79° 
  F. 
  In 
  these 
  the 
  maximum 
  variation 
  was 
  3.2° 
  F., 
  the 
  

   minimum 
  0.6° 
  F. 
  Ten 
  healthy 
  animals 
  (did 
  not 
  react 
  to 
  tuber- 
  

   culin) 
  in 
  the 
  same 
  herd 
  gave 
  an 
  average 
  variation 
  of 
  2.08° 
  F. 
  In 
  

   these 
  the 
  maximum 
  variation 
  was 
  4.1° 
  F., 
  the 
  minimum 
  1° 
  F. 
  

   The 
  lowest 
  temperature 
  was 
  usually, 
  but 
  not 
  invariably, 
  in 
  the 
  

   morning, 
  and 
  the 
  highest 
  in 
  the 
  afternoon 
  or 
  evening. 
  I 
  have 
  

   appended 
  the 
  records 
  of 
  the 
  temperature 
  of 
  two 
  of 
  these 
  animals 
  :

  Initial 
  Temperature
