air-waves have ceased. The impression produced by the words 
may persist even if they carry no thought. In my boyhood days 
I learned by many repetitions of the words, the names of all the 
counties in New York. They were repeated in concert by the 
young seekers after knowledge. For half a century I gave no 
attention to this subject. The family had moved to a more 
western state. I then learned to my surprise that I could still 
repeat those names in alphabetical order. 
Is it possible that all of these sound waves had made a per- 
manent impression upon molecular structures within the brain? 
A camera picture representing several landscapes, images of 
which have been superposed upon the same plate, would not be 
very instructive. 
The sound waves representing the names of all the counties 
in New York would be spread over a radial distance of more 
than eight miles, in every direction from their source. In the 
brain they are apparently superposed on the same tissue. Repe- 
tition from day to day impresses them more and more distinctly 
upon the receiving device, and there is no danger of an over ex- 
posure. And it appears that however much of the know- 
ledge of the past we may have accumulated in the mental store- 
house, this increases our capacity for acquiring more. 
The sending of messages by means of air waves has serious 
limitations. The messages cannot be sent over a long distance. 
To avoid this difficulty, and to secure and preserve a more 
reliable record of the oral traditions of the past, another system 
of wireless transmission was devised. By this later method 
messages could be sent to any distance, and they could be 
handed down through centuries to follow. As an example 
we find in Jewish history, I] Chronicles XXXVI, 22 and 23, 
and in Ezra I, 1-3, a statement that Cyrus, King of Persia, 
made a proclamation throughout all his Kingdom, and put it 
also in writing. In Ezra IV, V, VI, and VII, we have copies of 
letters passing to and fro between Kings of Persia and their 
subjects. 
In this system of wireless transmission John Doe gives 
through brain and nerves a directive motion to certain muscles 
of hand and arm, instead of to vocal organs. The receiver of 
the message also makes use of a wholly different receiving 
apparatus, from that used in oral transmission. Ether waves
