lion was then removed, and its attractive force determined, which 
was 20° ; and so on of the rest in succession. The deviation of 
the needle produced by the north pole of each in succession was, 
No. l.,19°; No. 2., 20°; No. 3., 20°; No. 4., 21°; No. 5., 20° 4 ; 
No. 6., 20°4 ; and of the south poles, No. 1., 4° ; No. 2., 4^° ; 
No. 3. 4J°; No. 4., 4°; No. 5., 4°; and No. 6., 4° *. If, in the 
magnetising powers, any change in the magnetism of each particle 
had taken place, it is evident that there must have been a greater 
attraction of northern polarity in the fragment at the North 
Pole, than in that at the south ; and that in the central frag- 
ments, which, before separation, were without attractive force, 
there must have been less magnetic intensity than in the frag- 
ments detached from the extremities, neither of which effects 
occurred : it is therefore evident, that the magnetisms were equal- 
ly distributed throughout the bar, even when its condition was 
such, that its poles exhibited a powerful degree of magnetism, 
and its centre none. 
The manner of the existence of the magnetic principles, there- 
fore, is in each particle ; and the phenomenon of the magnetic 
condition seems to consist of such an arrangement of the prin- 
ciples as may form a battery of magnetic particles. Whether 
this arrangement is effected at the moment of giving the sen- 
sible magnetism to the body, by a decomposition of the two 
magnetisms (two principles being supposed), which were before 
neutral in each particle by combination ; or whether it consists 
in giving a new arrangement to the magnetic principles, accord- 
ing to the axes of the bar, supposing them to be moveable in 
the particles ; or whether it may consist of a change in the posi- 
tion of the molecules of the iron into the required arrangement, 
is uncertain ; but, in either case, the apparent phenomena must 
be similar. If the first supposition be the true one, then the 
magnetic condition is the decomposition of the magnetisms, and 
their arrangement in a certain order, according to the direction 
of the axes of the magnet ; and the unmagnetic condition, the 
mutual neutralising of the two principles in each particle. If 
the second be the true one, then the magnetic condition requires 
* The reason why the southern poles had less magnetic force than the 
northern, has not yet been investigated.
