238 PECULIARITIES IN THE MAGNETISM 
68. The grand axiom in all reasonings of this 
nature is simply this :—No two particles of matter 
canoccupy the same place at one and the same time. 
By keeping this axiom in view we are led easily 
to understand that either additions or abstractions 
of the calorific matter, to or from any body, dis- 
turb both the electric and magnetic equilibrium, 
if such previously prevailed, in that body. It is 
thus, in fact, that our thermo-electric, and thermo- 
magnetic phenomena are produced ; and that 
reciprocally, calorific phenomena as decidedly ema- 
nate from magnetic and electric disturbance or 
excitement. 
69. Now, although the display of heat by mag- 
netic excitement, and the display of magnetism by 
calorific excitement, are, in many cases, entangled 
by electric agency, which plays an intermediate 
part in the process; it is a well established fact 
that additional portions of calorific matter forced 
into the substance of a magnet, disturb its powers 
by direct action ; and it has been shown in the 
first section of this memoir, that the magnetic 
poles are absolutely transplaced by the direct 
action of heat, which invariably repels these poles 
from itself; showing that, as heat is introduced 
to any particular part of the steel bar, the mag-
