The other chief results of annealing are to increase the per- 

 niealjility and to lower the hysteresis loss. The values of the 

 permeability ^a did not rise to nearly the values obtained by 

 other observers. For unannealed " Stalloy "' the maximum is 

 2660 at an induction of about 40(K) and in the annealed rises 

 to 3500 at an induction of about 6000.

Tlie more inqwrtant results of the ex])eriments for alterna- 

 ting currents will be readily seen by reference to the accom- 

 panying figures while their more accurate details are given in
