5. Structure of Iron Spectrum. 



After a simplification of" the spectrum had been achieved, 

 as explained in this paper, and lines of common origin 

 classed together, it was, of course, natural to look for the 

 possible existence of still closer relationships connecting- 

 lines or groups of lines of the same class. Although no
