Fig. 53 shows that the observed points; lie on a straight hne

 curvature of the separation curve, but it is within the errors of 

 experiment. 



Discussion of the Results. 



Examining the preceding results, we find some similarity 

 and regularity among manj'^ lines. Of the nine strong violet lines, 

 the specific separation increases in each group with decreasing 

 wavelength,'^ the rate of the increase being larger for the more 

 refrangible group, and the separation of the first line larger for 

 the less refrangible. The lines 4415* 13 and 4325*78, forming 

 the first of the first and the second group respective!}^, give 

 diffuse components, and the separations are not proportional to 

 the magnetic field, but the broadening and the loss of intensity 

 in strong fields are more conspicuous for the former line. On the 

 plates photographed with the strongest fields o/v-and 4%-com- 

 ponents are fomid for 4415*13, and the 7>-component of 4325'78 

 indicates some fine resolution which, I think, consists of three 

 componunts, while 4071'75, the first line of the third group, 

 appears as a sharp triplet of the separation proi)ortional to the 

 magnetic field. These lines seem to have 7, 5 (or 7) and 3 

 components respectively. The rest of these nine lines give sharp 

 triplets, the separations being exactly proportional to the magnetic 

 field. 



( )f tlie nine strong lines, seven, which were measured most 

 accurately', give the separations proportional to the magnetic field 

 as if no mutual influence existed between the radiating electrons, 

 yet the divergent values of the specific separations show that 

 Runge' s rule does not hold among these fines. The ratios of 

 these separations to the normal value are given in the I'ollowing 

 table.
