n und n sind Skalentheile der Variationsapparate fiir Declination und 

 horizontale Intensitat. 



t ist die Tempera tur am Bifilarapparate in Graden Reaumur. 

 Zur Verwandlung- der Skalentheile in absolutes Mali dienen folgende Formeln : 

 Declination D =11022'-05 + 0'- 763 (w— 100) 

 Horiz. Intensitat 5"= 2-03262 + 0-00009920 (500— w') + 0-000745^.
