  case 
  of 
  Labourer 
  No. 
  7, 
  there 
  was 
  no 
  additional 
  work 
  during 
  the 
  night 
  of 
  

   Thursday, 
  July 
  31st, 
  and 
  the 
  CO2 
  ordinate 
  was 
  correspondingly 
  low. 
  The 
  

   average 
  CO2 
  (gross) 
  for 
  the 
  last 
  three 
  hours 
  was 
  6"7 
  c.c. 
  per 
  second, 
  i.e., 
  

   allowing 
  4 
  c.c. 
  per 
  second 
  for 
  resting 
  C0 
  2 
  , 
  the 
  working 
  C0 
  2 
  was 
  only 
  27 
  c.c, 
  

   equivalent 
  to 
  54 
  Kals 
  per 
  hour 
  (= 
  27"96 
  Kals 
  per 
  hour 
  per 
  metre). 
  

  

  To 
  ascertain 
  the 
  effect 
  of 
  low 
  temperature 
  upon 
  energy 
  output, 
  we 
  must 
  

   take 
  only 
  periods 
  of 
  piece-work 
  in 
  cold 
  storage, 
  e.g., 
  in 
  the 
  case 
  of 
  Labourer 
  

   No. 
  7, 
  the 
  work 
  during 
  the 
  mornings 
  of 
  August 
  5th, 
  6th, 
  and 
  7th 
  was 
  at 
  full 
  

   pressure, 
  the 
  amount 
  of 
  meat 
  that 
  had 
  to 
  be 
  stored 
  was 
  greater 
  than 
  could 
  be 
  

   moved 
  during 
  the 
  normal 
  hours, 
  the 
  pay 
  was 
  on 
  the 
  piece-work 
  scale, 
  and 
  the 
  

   physiological 
  output 
  of 
  energy 
  can 
  be 
  considered 
  as 
  maximal.
