416 C. A. Chant — Reception of Electric Waves. 



The resonant lengths are given in table 3, but the curves, 

 being quite similar to I, tig. 6, are not shown. 



The conclusion was that the coherer did not alter the reso- 

 nance, that it behaved like its length of good conductor. This 

 agrees with Kiebitz's* results. 



Jf.. Exploration of Wires receiving Radiation from the Simple 

 Marconi Transmitter. 



In these experiments the antenna was 3 meters long, with 

 the receiving wire (nnless otherwise stated) 1 meter distant 

 The general arrangements are shown in tig. 7.

The receiving wire in every case but the last was 650 cms 

 long, which length was found in experiments just described 

 (see curve I, tig. 6) to be resonant with the transmitter.
