  These 
  determinations 
  show 
  clearly 
  that 
  the 
  effect 
  of 
  an 
  

   increase 
  in 
  the 
  amount 
  of 
  salt 
  in 
  solution 
  produces 
  an 
  

   increase 
  in 
  the 
  absorption. 
  These, 
  however, 
  are 
  not 
  directly 
  

   proportional; 
  but, 
  as 
  seen 
  from 
  the 
  form 
  of 
  the 
  curves, 
  

   the 
  relation 
  appears 
  to 
  be 
  a 
  logarithmic 
  one. 
  This 
  agrees 
  

   with 
  what 
  has 
  been 
  pointed 
  out 
  by 
  Lord 
  Blythswood 
  and 
  

   Dr. 
  Marchant. 
  

  

  Having 
  investigated 
  the 
  variation 
  in 
  absorption 
  with 
  varia- 
  

   tion 
  of 
  density 
  in 
  solutions, 
  a 
  comparison 
  of 
  several 
  solutions 
  

   of 
  a 
  given 
  specific 
  gravity 
  was 
  then 
  made. 
  The 
  result 
  of 
  

   the 
  comparison 
  is 
  shown 
  in 
  Tables 
  VI. 
  and 
  VII., 
  the 
  former 
  

   containing 
  a 
  series 
  of 
  chlorides 
  and 
  the 
  latter 
  a 
  series 
  of 
  

   sulphates, 
  with 
  a 
  few 
  other 
  salts, 
  all 
  of 
  a 
  specific 
  gravity 
  of 
  1*06.
