having their origin in the sun now come from the sheet of paper 
on which thoughts are recorded. They pass into the eyes and 
form images of the ink-marks and of the paper which bears 
them, upon his retinal membranes. The message is not now a 
fleeting one. If he does not understand he can cause the image 
of each word to fall repeatedly upon the sensitive spot of his 
retina. These ether waves produce vibrations in nervous tissue 
leading to him through the brain along a wholly different chan- 
nel of communication from that used in oral transmission. The 
tissues which are now active cannot respond to sound vibra- 
tions in air, and the tissues leading to him through the ear 
cannot respond to ether waves coming from a written message 
upon a sheet of paper. In either case the conscious being re- 
ceives the same thought, if the same thought is sent. 
He has learned how to operate either of these wireless sys- 
tems and he can serve either as the sending or the receiving 
station. In this connection it may be pointed out that a con- 
scious being can send a wireless message to himself. When 
one examines the directory of a telephone system, and learns 
by means of ether waves passing into his eyes, the telephone 
station and number which he wishes to call, he may save him- 
self trouble if he will give oral utterance to the name and 
number of the station. He is thus making use of both systems. 
He is receiving a message through nerves leading from his 
eyes, and he is sending to himself the same message through 
the wireless system which is operated by means of air waves. 
The result is to impress the desired information much more 
clearly upon himself, than would be the case if he were to use 
only one of these methods. He is much less likely to forget. 
It is well known that a telegraph operator can send or 
receive and write messages for hours, without having the 
faintest knowledge of the thoughts or words which he is send- 
ing or receiving. While doing amateur work in telegraphy 
I have found myself in the middle of a column of newspaper 
material with no knowledge of any statement or word which 
I had been sending, The only evidence that no mistake had 
been made, was the fact that the key at the other end of the 
line had not been opened in order that an interrogation point 
might be sent to me. I am told of one case in which an 
operator first learned of the death of his mother, when a tele-
