Mean, 22° 50' - Mean, 92° 24' 



By placing this result beside former determinations, we have, 



These results have received a very remarkable confirma- 

 tion from the observations both of the variations and dip made 

 during the voyages of Captain Ross and Captain Parry. In 

 August 1819, Captain Parry was north of the magnetic pole, 

 and from his measure of the dip, viz. 88° 37', on the 11th 

 September 1819, the expedition must have been about 3° north 

 of the magnetic pole ; but they were then in 74° 27', conse- 

 quently the pole must have been in 71° 27', or its distance from 

 the pole of the globe must have been 18° 33'. We may 

 therefore conclude, that the position of the strongest pole N in 

 the northern hemisphere is well determined. 



2. On the Position of S, the strongest Magnetic Pole in the 

 Southern Hemisphere, south of New Holland. 



By combining the observations made by Captain Cook in 

 1773 and 1777, and those made by Fourneaux in 1773, Pro-
