Following the previous papers (Magono and Kikuchi, 1963, 1965; Kikuchi, 1965), studies on positive electrification associated with the melting of the ice specimen were carried out by experimental method. During the experiment, it was observed that a number of droplets burst from the melting surface of ice specimen. And it was observed that these droplets carried negative charge, and the magnitude of the negative charge was in the order of 10-7 to 10-5 esu. On the basis of this result, the relationship between air bubble concentration and positive charge in melting ice (Kikuchi, 1965) was clarified.
