Figure J. — The effect of electrode spacing in relation to the angle 

 of electrical field using 2-inch electrodes at a width of 

 electrical field of 2 feet with a voltage gradient of 

 1 volt/cm., a pulse frequency of 8 piilses/sec, a pulse 

 duration of kO milliseconds, and a square wave form.
