Here the 1-step reversals give a smaller " throw," indicating a smaller 

 flux change, than the 3-step reversals, but it is to be noted that the 

 first 1-step reversal gave a throw very nearly as large as that given by 

 the 3-step reversals, though the general tendency of the 1-step reversals 

 was to reduce the throw. 



A demagnetization and reversal of the order of steps, that is, putting 

 the series of 1-step reversals first, yielded the following. Three of the 

 first 55 reversals are recorded.
