Zur Reduction der Ablesungen am Bifilar hat man folgende Formelii : 

 fur Juni 1689: H = 2.0675—0.0002233 [(160— L) — 4.116 (t— 15)], 

 fiir Juli 1889: H = 2.0680—0.0002233 [(160— L) — 4.116 (t— 15)]. 



Die Vertical-Intensitiit erhiilt man aus den Formeln : 



im Juni 1889: V = 4.0627+0.0005635 [(L— 70+5.137 (ti— 15)], 

 im Juli 1889: V = 4.0641-+-0.0005635 [(L— 70+5.137 (ti— 15)]. 



* Diese Beobachtungen wurden an dem Wild-Ede Imann'schen System (Umfilar, Bifilar undLloj 

 sche Wage) ausgelQhrt. Horizontal- und Vertical-Intensitat in Scalentheilen.
