  I 
  could 
  slide 
  it 
  up 
  or 
  down 
  and 
  fix 
  it 
  

   in 
  any 
  position 
  at 
  pleasure. 
  Measuring 
  the 
  distance 
  between 
  

   the 
  ring 
  CO 
  and 
  the 
  free 
  end 
  of 
  the 
  wire, 
  with 
  Grunow's 
  

   cathetometer, 
  and 
  measuring 
  at 
  the 
  same 
  time 
  the 
  resistance 
  

   corresponding 
  to 
  this 
  length, 
  I 
  obtained 
  the 
  data 
  necessary 
  for 
  

   constructing 
  resistance 
  as 
  a 
  function 
  of 
  length, 
  for 
  the 
  tempera- 
  

   ture 
  of 
  the 
  bath. 
  In 
  this 
  way 
  the 
  second 
  and 
  third 
  columns 
  

   of 
  table 
  1 
  were 
  found. 
  

  

  Combining 
  the 
  results 
  of 
  these 
  four 
  columns 
  by 
  graphic 
  

   interpolation, 
  I 
  obtained 
  the 
  fifth 
  and 
  sixth 
  columns 
  in 
  which 
  

   volume 
  is 
  expressed 
  in 
  terms 
  of
