  Density. 
  

  

  From 
  an 
  extended 
  series 
  of 
  experiments 
  on 
  water, 
  made 
  at 
  

   various 
  temperatures, 
  we 
  proved 
  that 
  the 
  absorption 
  is 
  

   independent 
  of 
  the 
  temperature. 
  All 
  subsequent 
  experiments 
  

   were 
  made 
  at 
  room 
  temperature, 
  which 
  varied 
  between 
  20° 
  

   and 
  25° 
  C. 
  

  

  In 
  order 
  to 
  find 
  the 
  effect 
  of 
  concentration 
  on 
  the 
  power 
  

   of 
  absorption, 
  a 
  number 
  of 
  salt 
  solutions 
  at 
  different 
  concen- 
  

   trations 
  were 
  investigated. 
  In 
  each 
  case 
  a 
  concentrated 
  solution
