The forms of applicatiou used in electro-therapy are :conyectite -\Disruptive (- discharges,conductite 3 A co)STECTiVE discharge occurs when electricity of a high poten-tial discharges itself at a pointed conductor by accumulating there■vrith a density sufficient to electrify the neighboring particles of air(these particles then flying off by repulsion), and conveying awaywith them part of the discharge. This form of application is illustratedin the use of the static iath, the breeze, and the spray as given offfrom metal electrodes, the high-frequency discharges from glass vacuumtubes, etc. The DISRUPTIVE discharges embrace the various sparks,—the long^short, and friction. The CONDUCTIVE discharge is derived from an electrified conductor.This may be a continuous current flowing through a thin wire connectingthe knobs of an influence machine or joining the positive pole of abattery to the negative pole.
