Magnetic Separations of the Lines cf Iron, Nickel and Zinc in Different Fields. 33. 



Table XX. 



From tJie last column of the table we see that the deviations 

 from the mean are less than 2%, except for three points. Hence 

 we can say that J?^ is nearly proportional to the fields applied. 



Plate XV, Fig. 2. 



The results of former investigators are: 



(21) ;:3581-20. 



Intensity 10; triplet, and each component is intense in com- 

 parison with that of other lines on the same plate; character b. 

 The determination of the fields is the same as in the case of
