WIRELESS TELEGRAPHY.
The electrical influence of ether waves,
a wireless force across country, through
water or hills, from a flying train and be-
tween ships at sea 186,000 miles in a second,
or seven times round the world. Attained
speed of messages so transmitted 15 words
per minute, radiating outwards in every
direction, the electricity of the ether being
energised and diffused through the infinity
of space.
The great experimentalists and dis-
coverers have been Franklin, Watson,
Nikola Tesla, Winckler (1746), Professor
Morse, Dr Oliver Lodge, Sir Wm. H.
Preece, Joseph Henry (1838), Professor
Trowbridge, Maxwell, Elisha Gray,

rays or waves.

waves (X rays).
In 1893 Sir W^m. Preece reported ihe
