I. Introduction, 



THE problem treated in these pages was suggested by the 

 following experimental results, for a fuller account of 

 which I may refer to a previous paper f . 



A series of wave-trains generated by an oscillator were 

 allowed to propagate themselves along a double- wire circuit 

 LL' about 100 metres in length. At the middle of the circuit 

 the wires were run through a jar containing a certain depth 

 AB of distilled water, alcohol, or a very dilute electrolyte.
