n und n sind Scalentheile der Variationsapparate fiir Declination und 
horizontale Intensitat. 
t ist die Temperatur am Bifilarapparate in Graden Réaumur, 
Zur Verwandlung der Skalentheile in absolutes Mafs dienen folgende Formeln: 
Declination: D = 11°25'.94 + 0.763 (n—100). 
Horiz,-Intensitét: H = 2-02872 + 0°.00009920 (500—-n’) + 0°000745 ¢.
