This arc gap, asFessenden terms it, is really the ordinary spark gapemployed in all the older systems of wireless teleg-raphy; it has nothing in common with the tu/ied arcof Elihu Thomson, and is entirely different from themusical arc of Duddell, the speaking arc of Simon,or the continuous oscillation arc of Poulsen. A new claimant for wireless telephonic honors isDeForest. Of his apparatus the Scientific Americanpublishes an account in its issue of September 28, illustrate how nearly his arrangements for telephon-ing without wires are lik
