6. In order to exhibit graphically some of the more 

 striking results contained in the preceding tables, the curves 

 in figs. 1 and 2 have been plotted. In fig. 1 the abscissa? 

 are distances x from the origin or magnetizing solenoid and 

 the ordinates of one set of curves are the natural logarithms 

 of the amplitudes of the first harmonic of the flux at different 

 distances, while the ordinates of the other set of curves are 

 the retardations in phase of the first harmonic of the flux at 

 different distances behind that of the initial flux where 57 = 0. 



It will be seen that the log/i, x, curves are far from being 

 straight lines as Zenneck assumed for the basis of his 

 theoretical work. This is still more clearlv shown in fig. 2
