118 AKSEL S. STEEN. TERRESTRIAL MAGNETISM. [NORW. POL. EXP. 



SUMMARY OF THE RESULTS. 



In the subjoined table will be found all the values of the horizontal 

 intensity deduced either from deflection or vibration observations, and the 

 mean value for every place of observation indicated by latitude and longi- 

 tude. In the calculations of the means, I have given only half the weight 

 to the determinations made with magnet VI, as, from what has been shown 

 above, the values employed for the constants of this magnet cannot be 

 assumed to be nearly so accurately determined as those of magnet V. 



In calculating the means for the 4th October, 1895, I have not included 

 the results of the last 3 series of vibrations, one of them being incomplete, 

 and the other two taken during quite exceptionally violent magnetic 

 disturbance.
