  On 
  a 
  Numerical 
  Value

  "Efficiency." 
  

  

  The 
  calibration 
  of 
  a 
  labourer 
  is 
  essentially 
  completed 
  when 
  his 
  rate 
  of 
  C0

  has 
  been 
  determined. 
  

  

  A 
  further 
  step 
  may 
  be 
  taken 
  by 
  measuring 
  the 
  efficiency 
  of 
  a 
  given 
  labourer 
  

   for 
  a 
  given 
  piece 
  of 
  artificial 
  work 
  of 
  which 
  the 
  mechanical 
  value 
  is 
  known
