maximum leakage coefficient, and increases the distance from 

 the origin at which these two maxima concur. 



As a result of this series ot' experiments it is plain that 

 what may happen at any one point o£ the rod, both as regards 

 rate of retardation (or of advance as the case may be) of 

 phase and leakage depends both on the position of the point 

 and on the value of the resultant flux at the point, and if we 

 followed previous investigators in computing a "*' velocity of 

 magnetization" we should obtain different velocities for the 

 same flux and frequency, provided the points for which 

 the velocity is computed were at different distances from the 



magnetizing coil.

8. Specimen A was now reduced in length in successive 

 steps by cutting each time equal portions off its two ends. 

 For each length one series of observations was taken in 

 which the initial flux and the frequency were approximately 

 the same as in the series already given for the full length in 

 Table III. The results obtained are given in detail in Tables 

 VI. to XL, and the general effect of reduction in length on 

 the lag in phase and on the logarithm of the amplitude of 

 the first harmonic of the flux is exhibited in fig. 6.
