Magut'tic Separations of Iron Lines in Different FicMs. (j9 



mdiating electrons, but tlie (li\ergeiit values of the specific 

 separations seem to indicate the existence of coupling. Moreover 

 the separations of a number of lines which are not proportional to 

 the magnetic held, seem to indicate the existence of some mutual 

 influence, though the measurements are not sufhciently accurate. 



U. Many iron lines apparently show simple resolutions into 

 diffuse components, which are likely to be resolved again into 

 hue components, if they are examined in stronger magnetic fields 

 with an instrument of higher resolving power.
