for the non-leaky line {b = ()). From these curves we see that, as 

 the length of the line and the parameter a increase, the relative mag- 

 nitude of the tail, as compared with the head of the wave, increases. 

 Finally when the line becomes very long, the head of the wave be- 

 comes negligibly small, and the wave, except in the neighborhood of 

 its head, becomes very close to that of the corresponding non-inductive
