MAGNETIC OBSERVATIONS 



Tabular summary of observations of magnetic indications at Teplitz ffay— Continued

* These observations were made at Italian station. 



Note. —When the observations of June 20 at the Italian station were being made an iron bolt was found at 

 the foot of the pier ; needle was not affected while it was being removed, but probably the observations of 

 June 6 are vitiated. 



The following monthly mean values for magnetic dip result from these observations : 



•Omitting October 12, 1903. •" Including two values, needles No. i and No. 2. 



In adopting a mean value from this summary it has been deemed best to reject the obser- 

 vations of October 12, 1903, as probably defective, owing to improper setting for the magnetic 

 meridian. From the remaining sixty sets of observations with two needles each the resulting 

 inclination at Teplitz Bay is— 



83° J2.'4 for epoch J904.J3.
