 practically the same as if the other wires had been removed from the 

 line. It will be seen that the crosstalk coefficients for curves B are

less than those for curves A. The coefficients of curves B involve 

 tertiary circuits, however, since there could be crosstalk currents in 

 the phantom of the two test pairs and also in the ghost circuit involving 

 wires 1 to 4 with ground return.
