It is found that the reaction between an electrified body and a neighbouring neutral one, whereby the electricity in the neutral body is inductively decomposed and attraction produced, undergoes a modification when the neutral body is considerably heated. Under many circumstances it is found that the electrified body is rapidly and completely discharged. The action of discharge is shown to depend mainly upon the following conditions: firstly, the temperature of the discharging body and its distance from the electrified one; secondly, the nature (positive or negative) of the latter’s electricity. A suggestion is made as to the existence of an electrical coercitive force, the presence of which together with its diminution by heat would explain many observations described by Guthrie in the paper.
