In the Antimony spectrum I found further a second group of 
translation series, the former of which has as formula: 
| 109675.0 
108 A—! = 47810.99 — ———_—___________c_c_ 
(@ + 1.616567 — 332,37 A—1)?

Remarkable is the very great deviation for «=4, while 7=5 
is again in perfect harmony. Earlier investigators HARTLEY and ADENEY 
found A 2263.5 for this line, which lies just between the value found 
by Kayser and Runer and mine. 
By translation we may obtain the series: 
109675.0

4 2375.74 lies near A 2373.78, which has been observed, and for 
which Exner and Hascurk remark : 2 +, so diffuse. Possibly this diffuse- 
ness is caused by the faint line 2375.74 in the immediate neigh- 
bourhood. 
Of a number of translation series, which lie for the greater part 
in the SCHUMANN region, indications are available, which I will give 
together in the following table with their respective asymptotes, and 
for each of them one calculated value in the as yet uninvestigated region.
