found that Kayserr’s formula, in its original form, did not sufficiently sable the 
measurements, which had to be represented by an equation of the form 
108A-!=a + bm? + em-3, 
This modification must of necessity complicate the theoretical aspect of the problem, 
inasmuch as the line-series would appear to be of two different types, in which the 
structure of the series is seemingly determined by different conditions. But we shall 
see now that the series of all these elements are represented by the same type of the 
RYDBERG-THIELE equation which we had employed in the foregoing discussion, and 
hence that a separation in two different types, such as is demanded by Kayszr’s 
formula, is not required. This must be considered as an important advantage in our 
equation, which will become more apparent in the later discussion of the results.
