The following table exhibits the variation of the compass iu 

 different latitudes and longitudes according to the observations 

 of Capt. Sabine, with an azimuth compass contrived by Capt. 

 Kater. These observations are entitled to particular attention,

 the position of one of the magnetic poles. It must be very 

 nearly N. latitude 75° 59', and longitude 64° 32' W. from Green- 

 wich. If we suppose this latitude and longitude to be correctly 

 given, the true position of this magnetic pole may be easily 

 found :
