  Abscissas 
  represent 
  half 
  wave-leogths, 
  ordinates 
  change 
  of 
  phase 
  by 
  reflection, 
  

   and 
  capacity 
  of 
  ends. 
  

  

  tible 
  difference 
  or 
  change 
  in 
  the 
  angle 
  of 
  phase. 
  Such 
  corners 
  

   did 
  not 
  therefore 
  affect 
  to 
  any 
  observable 
  extent 
  the 
  capacities 
  

   of 
  the 
  end 
  systems, 
  for 
  any 
  frequencies 
  used. 
  

  

  But 
  when 
  the 
  wires 
  were 
  bent 
  out 
  from 
  each 
  other 
  the 
  

   clearness 
  of 
  node 
  was 
  very 
  much 
  impaired 
  — 
  the 
  greater 
  the 
  

   angle 
  the 
  less 
  sharp 
  the 
  definition 
  — 
  due 
  to 
  the 
  double 
  reflec- 
  

   tion 
  then 
  existing. 
  

  

  If 
  the 
  distance 
  between 
  the 
  ends, 
  bare 
  or 
  with 
  balls 
  attached, 
  

   is 
  kept 
  flxed 
  and 
  a 
  certain 
  section 
  of 
  the 
  wires 
  next 
  adjoiniug 
  

   is 
  bent 
  or 
  bowed 
  otit, 
  from 
  straight 
  and 
  parallel 
  wires 
  into 
  

   curved 
  or 
  circular 
  forms, 
  the 
  last 
  quarter 
  wave-length 
  is 
  

   observed 
  to 
  shorten, 
  then 
  increase 
  again. 
  The 
  capacity 
  of 
  the 
  

   section 
  is 
  changed, 
  until 
  when 
  at 
  last 
  the 
  wires 
  are 
  bent 
  out 
  

   and 
  back, 
  as 
  in 
  {a\ 
  Fig. 
  3, 
  the 
  capacity 
  may 
  be 
  less 
  than 
  for 
  the
