Art. XII. — Observations on the Position and Revolution of 

 the Magnetic Poles of the Earth. By Christopher Han- 

 steen, Professor of Astronomy in the University of Nor- 

 way. 



As we had the satisfaction of first introducing the English 

 reader to the important researches of Professor Hansteen, con- 

 tained in his valuable work on the magnetism of the earth, * 

 we are desirous to keep our readers in the current of his very 

 interesting and important inquiries. 



In the work now quoted, Professor Hansteen computed, by 

 means of the observations which he then possessed, the posi- 

 tions of the four magnetic poles of the globe, and from these 

 results he calculated the following table, which shows the po- 

 sition of these poles during the first half of the present century. 

 In this table,
