n und n sind Scalentheile der Variationsapparate fiir Declination and 

 horizontale Intensitat. 



t ist die Temperatur am Bifilarapparate in Graden Celsius, T die Zeit 

 in Theilen des Jahres vom 1. Jan. an geziihlt. 

 Zur Verwandlung der Scalentheile in absolutes Mass dienen folgende Formeln:
