Under every component it is indicated from what jump or jumps 
above 
it is supposed to have arisen. A — the component expresses 
under 
that it is polarized an When both signs occur, the two components 
coincide or the polarization is incomplete. Between ( ) are placed 
the so-called superfluous components, which have not been found 
in the observation. The adjoined notes of interrogation will be dis- 
cussed further on. 
First a few words about the superfluous components. By far the 
greater part are extreme outer components. As the outer components 
that have been observed, are mostly very faint, it is possible that 
the theoretically found components are so faint that they could not 
be observed up to now. These components originate namely by 
jumps from and to the most greatly deformed paths, and according 
to SoMMERFELD these are less probable than the less deformed ones, 
so that the number of jumps of the electron from these greatly 
deformed paths is relatively much smaller, hence the produced 
component much fainter. 
This explanation, is however, not applicable to the question 
whether the middle components of J’ 2 and IId are superfluous. 
It would, however, also be possible that the “Kombinationsprinzip’”’ 
was dependent on a restrictive condition. Prof. Bor was namely 
of opinion, as appeared to me from a conversation on this question, 
that in its jumping the electron should also be bound to the condition 
that the angular momentum in initial and final path may not
