to the stronger magnet, and afford a very simple explanation 

 of the cause of the rapid diminution of the repulsive force, 

 and the change to attraction which takes place between mag- 

 nets of unequal intensity whilst they remain in these relative 

 positions. The appearances assumed by the particles of load- 

 stone may also be exhibited by strewing them on paper, glass, 

 &c, under which magnets have been previously fixed at pro- 

 per distances from each other, and gently tapping the surface, 

 till the arrangement is effected. 



I am disposed to regard the magnetic curves around the 

 magnet as induced towards its surface, and not thrown out 

 from it, the magnetic elements without, having the same pro- 

 perties as those within the magnet, and the opposite poles in 

 both cases alternating with each other throughout the whole 

 series. Hence a magnetic circuit is formed, and the tension 

 thereby produced between the opposite poles of a magnet 

 may essentially contribute to maintain its intensity. This
