  These 
  ratios 
  bring 
  out 
  the 
  fact, 
  which 
  has 
  since 
  been 
  

   abundantly 
  verified, 
  that 
  p 
  is 
  greater 
  than 
  p 
  v 
  i. 
  e. 
  that 
  

   the 
  contraction 
  does 
  not 
  cease 
  with 
  the 
  discharge 
  ; 
  the 
  amount 
  

   of 
  this 
  after 
  effect 
  being 
  about 
  7 
  per 
  cent, 
  of 
  the 
  contraction 
  

   during 
  discharge, 
  and 
  probably 
  the 
  same 
  for 
  both 
  signs 
  of 
  

   current.
