  The 
  results 
  in 
  three 
  cases 
  are 
  given 
  in 
  Table 
  II. 
  It 
  is 
  not 
  

   considered 
  necessary 
  to 
  give 
  more 
  than 
  these, 
  as 
  the 
  range 
  in 
  

   the 
  lengths 
  of 
  the 
  wires 
  used 
  is 
  not 
  sufficient 
  to 
  alter 
  the 
  

   general 
  character 
  of 
  the 
  observations. 
  The 
  lengths 
  of 
  the 
  

   circuits 
  given 
  in 
  the 
  table 
  are 
  those 
  when 
  maxima 
  deflexions 
  

   occurred, 
  corrected 
  as 
  previously 
  mentioned, 
  the 
  bridge 
  being 
  

   0"o0 
  metre 
  long.

  Rubens 
  (Wied. 
  Ann. 
  xlii. 
  p. 
  154, 
  1891) 
  has 
  shown 
  that 
  

   the 
  electrical 
  vibration 
  in 
  the 
  secondary 
  circuit 
  when 
  the 
  

   deflexion 
  is 
  a 
  maximum, 
  is 
  in 
  that 
  mode 
  of 
  vibration 
  required 
  

   for 
  resonance 
  with 
  the 
  vibration 
  in 
  the 
  primary 
  circuit. 
  

   Assuming 
  that 
  that 
  mode 
  of 
  vibration 
  of 
  the 
  primary 
  circuit
