  The 
  results 
  found 
  here 
  are 
  therefore 
  the 
  following 
  : 
  — 
  

  

  1. 
  When 
  the 
  liquid 
  is 
  not 
  stirred 
  at 
  all, 
  the 
  only 
  way 
  for 
  

   the 
  substance, 
  passing 
  into 
  the 
  solution 
  from 
  the 
  surface 
  of 
  

   the 
  solid, 
  to 
  pass 
  into 
  the 
  rest 
  of 
  the 
  solution 
  is 
  naturally, 
  as 
  

   known 
  long 
  ago, 
  by 
  diffusion. 
  The 
  amount 
  passing 
  in 
  this 
  

   manner 
  is, 
  however, 
  in 
  comparison 
  with 
  what 
  passes 
  at 
  the 
  

   maximum 
  revolutions 
  or 
  even 
  at 
  any 
  ordinary 
  speeds, 
  only
