Tables XII. and XIII. give the results of the experiments 

 with this specimen, the characteristics of the first harmonic 

 of the flux only being given. 



By comparing Tables III. and XII. one can see the differ- 

 ence in the behaviour of similar rods of iron and steel for the 

 same initial flux and the same frequency. Fig. 7 illustrates 

 the difference graphically. Thus, though near the origin 

 the rate of retardation of phase (dd/dx) is nearly the same 

 for both specimens (hence giving nearly equal fictitious velo- 

 cities of magnetization), yet in the steel rod the retardation 

 attains its maximum at less than half the distance from 

 the origin at which it attains its maximum in the iron rod, 

 and the maximum value in the latter rod is about three times 

 what it is in the former. Again, for the steel rod the leakage 

 coefficients are at first very much larger than for the iron one 

 (see fig. 8), either at equal distances from the origin, or for 

 equal fluxes; but when very low values of the flux have been 

 arrived at, the leakage coefficients are quite as small in the 

 steel as in the iron.
