force should raise up force in a body at a distance from it, is too hard 
sively, may even be converted, as far as we understand the matter, 
disappearing in one form to reappear in another; but it cannot be cre- 
ated or annihilated, or truly suspended, ¢.¢., rendered existent without 
action or without its equivalent action. The conservation of power is 
now a thought deeply impressed upon the minds of philosophic men ; 
of approach or separation of the bodies, involves the same result of 
creation or annihilation of power, as the creation or annihilation

Power, or the efficient source of the power, having pre-existed in the 
equivalent degree from some other bodies, and when taken off from 
the earth (by the disappearance of the latter) be disposed of on some 
ment or conceived by the mind. The second sub-case, or that of a 
new or another form of power, is also one which has never been
