Magnetic Separations of the Lines of Iron, Nickel and Zinc in Diffei-ent Fields. 55 



Intensity 20: very sharp triplet; character b. Plate I, Fig. 2 

 and Plate I, Fig. :J; Plate III, Fig. 2; Plate IV, Fig. 1. The 

 determination of the fields is the same as in tlie case of l\ 3619*39. 



Taj'.le XXXVIII. 



Al is linearly proportional to the fields applied as in all other 

 cases of sharp triplets. Plate XVIII, Fig. 3. The results of 

 former investigators are:
