Electric Communications without Wires. — It would seem from recent experiments that it is perfectly possible to convey a message for a certain distance along the earth without any conducting wire whatever. But M. Th. Du Moncel has explained to the French Academy (May 8) that the idea of communication without wires is far from novel, having been experimentally tested thirty years ago, both in England and America. Thus, messages were sent from Gosport to Portsmouth (and, we believe, across to the Isle of Wight), a distance of about three kilometres.
