CHAPTER XI
HOW WE REPRODUCE SPEECH
THE SCRIBE'S NOTE ON CHAPTER ELEVEN
In the first part of this chapter the electron explains the part it plays in ordinary telephony.
The reader will picture the transmitting instrument at the one end of the line influencing the receiving instrument at the distant end.
Towards the end of the chapter the electron turns its attention to the newer subject of wireless telephony, which has been accomplished now over a distance of several hundred miles.
