n und n sind Scalentheile der Variationsapparate fiir Declination und 

 horizontale Intensitat. 



t ist die Temperatur am Bifilarapparate in Graden Reaumur. 

 Zur Verwaudlung der Skalentheile in absolutes Maft dienen folgende Formeln: 

 Declination: D = 11''18'.88 + 0'.763 (n— 100). 

 Horiz.-Intensitat : H = 203367 + 0'.0J00992 (500 -w) + 000745 t.
