oscillating one, and the insulated cOnduc-
tor, or copper cable raised on the kite, or
mast, at once radiates electric waves
These waves. or impulses, are simultane-

directions from the tOpeof the transmit

record them at any given point
To do this. MsrcOni has applied what is
called a coherer to the ground end of the
vertical copper cable or wire correspond
ingly elevated at the transmitting sta
ton on pole This cOherer is "A small
glass tube, into the ends of which two
silver plugs are fitted. In the gap be-
tween the plugs a mixture Of nickel and
silver filings is placed Joined with the
tube are a battery and Geographic relay.
The metal filings constitute non-cOn-
ductor, except when an electric wave
falls upon them.
When one of the impulses started
through the ether from the transmitting
station is conducted down the copper
cable or wire of the receiving station TO
the coherer these metal filings cohere.
The tube becomes at once. Wnat II was
not before, a conductor of electricity. The
current from the battery Immediately
passes through The tube, actuates the re-
ment
The period of this activity in the neces-
Sary apparatus corresponds exactly 10 the
time during which tho key is pressed at
he transmitting station That proves
Marcoui's case.
But other results have demonstrated it.
