(ol) Separations in a single field. 



Although the magnetic separations of iron lines in a single 

 field have been investigated by many phyicists, it may not be out 

 of place to report here the results obtained in the course of my 

 study of the above mentioned problem. (Plate II, Figs. 2, 3, 4 

 and 5; Plate V, Figs. 1, 2, 3, 4 and 5; Plate VI, Figs. 1, 2, 3
