Besides these six series, which are connected by a simple trans- 
lation, I have found some more in the tin spectrum that are con- 
nected. The first series of this group may be represented by the formula:

Why Exner and Hascuek give so great an intensity for 4 2421.78, ~ 
whereas this line is fainter than any of the others according to 
Kayser and Rvner, I do not know. 2 2386.96 only occurs with 
Kayser and Runes with the indication “sehr unscharf’. Exner and 
Hascnek have not got this line at all, which is very strange, indeed, 
in connection with the intensity 5, which Kayser and RuNGe give. 
Of this series I have found two translation series, which corre- 
spond with the two differences of frequency found by Kaysrr and 
RUNGE. 
The translation 5187.03 yields the series: 
109675.0
