2 2330.95 has not been observed, its intensity is possibly too slight. 
It lies in the neighbourhood of 4 2329.19 of Kayser and Runes, 
which, however, does not occur at all with Exnrr and HASCHEK. 
The two following series are in connection with this by translation. 
The former of them has as formula: 
109675.0

42507.74 does not oecur in the arc-spectrum. 
In the spark-spectrum, however, we find 4 = 2507.90 which cor- 
responds with this. Further terms have not been observed on account 
of their slight intensity.

0. r. o. means outside the region of observation. 
Further there are some more indications for other translation 
series, which lie further in the region of SCHUMANN, viz. that with 
the asymptotes: 
53251.07 to which A 2673.78 (Int. 5 ) and 4 2220.85 belong, and 
54951.35 to which 4 2554.72. (Int. 1) with 4 2139.89 may be 
counted. For a= 3 A 2003.88 is therefore o. r. 0.
