A glance at the columns for x — and \ x in Tables XVIII. 

 to XXI. will show that so far as phase retardation and leakage 

 coefficients are concerned, the general character of the results 

 is, the same as has been obtained from the other specimens; 

 and, as was expected, not only are these quantities much 

 reduced in magnitude, but also the effect of change of 

 frequency on them is less marked. In addition the appa- 

 rently coincident point of maximum phase retardation and 

 maximum leakage coefficient is much further removed from 

 the origin than in any of the other specimens. 



115. A much more striking result, however, is the way the 

 upper harmonics of the flux, and hence its wave form, vary as 

 the flux-wave passes along the specimen. In these series the 

 ratios /y/i and f-J f l of the amplitudes of the third and fifth 

 harmonics to that of the first are much larger than in the 

 previous ones, where the flux wave was almost sinusoidal. 

 We were therefore able to determine for this specimen these 

 upper harmonics both in amplitude and phase with certainty 

 for greater distances from the origin than for the other
