n unci n sind Scalentheile der Variationsapparate Far Declination und 

 horizontale Intensitat. 



t ist die Tem^eratur am Bifilarapparate in Graden Reaumur. T die Zeit 

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

 Zur Verwandlung der Scalentheile in absolutes Mass dienen folgende Formeln : 



Declination D = 11° 25' 17 + 0.763 (»- 100) 

 Horiz. Intensity .7=2.03278 + 0.0000992 (400— n') + 0.00107 *+ 0.00402 T.
