At present there is no outlook that etheric signaling overland will ever attain to the tremen- dous possibilities of telegraphy with wires. 142 WIRELESS TELEGRAPHY. S NOMENCLATURE. PART IV. APPARATUS. NOMENCLATURE. THE art which forms the subject-matter of this work is young and its nomenclature limited. " Wireless Tele- graphy" itself but a negative term is temporarily supplying the need of a positive designation. Neither " radio-tele- graphy" nor "wave-telegraphy" nor "etheric-transmission" s...atisfies. " Hertzian-wave telegraphy " is of unwieldy length and lacks euphony, No single word suitably denotes every kind of instru- mentality- affected by Hertzian or magnetic waves. " Detector " has been used in another sense. Mr. Tesla speaks of " sensitive-devices " ; Mr. Fessenden and others of a "wave-responsive-device. " " Responder " is too closely identified with the DeForest system to be ac- ceptable to competitors. " Resonator, " to denote a receiv- ing device, is objectionable on account of its alliterative and structural similarity with " radiator, " a transmitter.
