  Density. 
  

  

  of 
  the 
  salt 
  in 
  question 
  was 
  made 
  up, 
  and 
  the 
  percentage 
  of 
  

   the 
  rays 
  which 
  it 
  absorbed 
  determined 
  in 
  the 
  manner 
  already 
  

   explained 
  for 
  water. 
  The 
  density 
  as 
  compared 
  with 
  water 
  

   was 
  determined 
  by 
  means 
  of 
  a 
  Mohr-Wesphal 
  specific-gravity 
  

   balance. 
  The 
  solution 
  was 
  then 
  diluted 
  to 
  a 
  certain 
  extent 
  

   and 
  the 
  absorption 
  again 
  determined, 
  the 
  density 
  being- 
  

   measured 
  as 
  before. 
  This 
  was 
  done 
  for 
  several 
  densities 
  of 
  

   the 
  liquid 
  until 
  the 
  absorption 
  approached 
  that 
  of 
  water. 
  

   This 
  relation 
  between 
  density 
  and 
  absorption 
  was 
  investigated
