Figure 15.— Effect of electrode spacing In relation to electrode 

 diameter using a width of electrical field of 2 feet 

 at a 90° angle of electrical field with a voltage 

 gradient of 1 volt/cm., a piolse frequency of 

 8 pulses/sec, a pulse duration of kO milliseconds, 

 and a square wave form.
