  Mr.

  Miznno 
  on 
  the 
  Function 
  of 
  

  

  Plotting 
  these 
  results 
  we 
  obtain

  Thus 
  the 
  relation 
  which 
  the 
  capacity 
  of 
  the 
  condenser 
  hears 
  

   to 
  the 
  maximum 
  spark-length 
  between 
  the 
  terminals 
  of 
  the 
  

   secondary 
  circuit 
  with 
  various 
  primary 
  currents 
  is 
  made 
  

   clear. 
  

  

  Next 
  I 
  took 
  another 
  induction-coil, 
  11*5 
  centim. 
  in 
  diameter 
  

   and 
  21'5 
  centim. 
  in 
  length, 
  with 
  a 
  platinum 
  interruptor. 
  

   The 
  condenser 
  of 
  the 
  coil 
  was 
  taken 
  off, 
  and 
  the 
  adjustable 
  

   condenser 
  was 
  inserted 
  just 
  as 
  in 
  the 
  case 
  of 
  the 
  first 
  experi- 
  

   ment. 
  Also 
  the 
  mercury 
  interruptor 
  was 
  substituted 
  for 
  the 
  

   platinum 
  interruptor, 
  and 
  then 
  experiments 
  were 
  carried 
  on. 
  

   The 
  results 
  were 
  as 
  follows 
  :
