Zur Reduction der Lesungen des Bifilars und der Lloyd’schen Waage dienen dieFormeln: 
H = 2:0665—0- 0002257 [(160—L) —4:-116 (¢ —15)] 
V = 4:0567--0- 0005263 (L,—70). 
Lund L, bedeutet die Lesung in der Scala des Bifilars und der Lloyd’schen Waage, 
t die Temperatur. 
1) Die Daten fir die Vertical-Intensita&t sind der Lloyd’schen Waage des Magnetogra- 
phen entnommen, da die Lloyd’sche Waage von Edelmann neu justirt werden musste.
