  Although 
  the 
  observations 
  of 
  a 
  given 
  date 
  are 
  in 
  tolerably 
  

   good 
  accord, 
  considerable 
  discrepancy 
  is 
  found 
  between 
  the 
  

   mean 
  results 
  for 
  days 
  of 
  nearly 
  the 
  same 
  vapor 
  pressure, 
  such 
  

   as 
  May 
  28 
  and 
  October 
  21, 
  1904. 
  But, 
  on 
  the 
  other 
  hand, 
  

   days 
  in 
  which 
  the 
  aqueous 
  vapor 
  at 
  the 
  'surface 
  has 
  varied 
  in 
  

   the 
  ratio 
  of 
  1/0 
  : 
  7'5 
  (August 
  24, 
  1903, 
  and 
  January 
  9, 
  1906) 
  

   yield 
  almost 
  identical 
  results 
  by 
  the 
  reduction, 
  showing 
  that 
  

   the 
  method 
  is 
  competent 
  to 
  harmonize 
  a 
  wide 
  range 
  of 
  sum-
