Synopsis
Excerpt from Proceedings of the American Academy of Arts and Sciences, Vol. 4
When two persons receive a shock from a Ruhmkorff's coil by clasping hands, each taking hold of one wire Of the coil with the free hand, a sound proceeds from the clasped hands. The effect is not produced when the hands are moist. When either Of the two touches the body of the other a loud sound comes from the parts in contact. When the arm Of one is placed against the arm of the other, the noise produced can be heard at a distance Of several feet. In all these cases a slight shock is experienced SO long as the contact is preserved. The introduction Of a piece of paper between the parts in contact does not materially interfere with the production Of the sounds, while the unpleasant effects of the shock are avoided.
