Excerpt from Wireless Telegraphy: A Popular Exposition
When a new system of sending electric signals, in which no connecting wire was required between the two stations, came into prominence it was named from the most striking feature to the ordinary observer, namely the absence of the connecting wire.
The name is not logically defensible, for on the one hand the method of signalling known as Wireless Tele graphy involves the use of wires both in the trans mitting and in the receiving apparatus, and on the other hand it includes systems of signalling which are not popularly supposed to be electrical at all.
