SCIENTIFIC RESULTS OF ZIEGLER POLAR EXPEDITION 



INCLINATION 



Instrument, Methods, and Rbsults 



The same instrument and methods were used in the determinations of magnetic dip at the 

 Alger Island station as at Teplitz Bay (see pages 307 to 309). The observations were made on 

 the central pier in the observatory, the magnetometer at such times being removed from its 

 place. The results obtained are exhibited in the following table : 



Summary of observations of magnetic inclination at Alger Island 



From the above the mean value of the magnetic inclination at Alger Island, practically 

 applying to mean of day, is 



82° 45. '8 N for the epoch J 905.53. 



HORIZONTAL INTENSITY 



Instrument, Methods, and Results 



The instrument and methods used at the Alger Island station were the same as at Teplitz 

 Bay, already described in detail on pages 313 to 315. The following tabulation summarizes 

 the work at this station ; the various column headings are explained on page 313.
