We proceed to select some observations on the Aurora 

 Borealis : the following are by Capt. Franklin, made at Fort 

 Entreprise, in lat. 64" 28^ 24'^ N. ; long. 1 13° & 0'' W. 



" The arches of the Aurora most commonly traverse the sky, 

 nearly at right angles to the magnetic meridian, but the devia- 

 tions from this direction were not rare ; and 1 am inclined to 

 consider, that these different positions of the Aurora have con- 

 siderable influence upon the direction of the needle. When an 

 arch was nearly at right angles to the magnetic meridian, the 

 motion of the needle was towards the west ; this westward 

 motion was still greater when one extremity of an arch bore 

 301°, (or about 59° to the west of the magnetic north), that is, 

 when the extremity of the arch approached from the west 

 towards the magnetic north. A westerly motion also took place 

 when the extremity of an arch was in the true north, or about 

 36° to the west of the magnetic north, but not in so great a 

 degree as when its bearing was about 301°. A contrary effect 

 was produced when the same end of an arch originated to the 

 southward of the magnetic west, viz. when it bore from about 

 245° to 234°; and, of course, when its opposite extremity 

 approached nearer to the magnetic north. In these cases, I say, 

 the motion of the needle was towards the east."
