12 SCIENTIFIC RESULTS OF ZIEGLER POLAR EXPEDITION 



(6) In planes making an angle of 60° with the magnetic meridian : 



The normal dip for this station is 70° 26'. 4 N, as derived from the following observations 

 with earth inductor : 



Mean 



70 26.4 N 



These observations give the following corrections to the dip needles of dip circle No. 5676 : 



In view of the change indicated between 1903 and 1905 and the probability that the cor- 

 rection required becomes less as the dip increases, it is deemed best to apply no correction to 

 the dip observations.
