forces are modified, so as to give rise to new electrical 

 manifestations. Such a view might have been admis- 

 sible if forces were considered as independent entities, 

 capable of manifesting themselves in different ways, 



but with an inherent obstinacy of their own an inborn 



reluctance to change their mode of action— which could 

 only be overcome by the superior energy of some inde- 

 pendent, autocratic demon situated in each particle of a. 

 body. We will not speak of the waste of energy which 

 ^. would result, on such a supposition, from the everlast- 



' ^'"^i'arly,wk' ing conflict of these powers, because such doctrines are 

 of bodies ared now effete. Forces are not separable entities. They 

 ? heat diminii are merely modes, affections, properties— call it what 

 of the resistiE you will— of matter j and, therefore, necessarily vary 

 e to electrici:; with the molecular states of matter. When heat gives 

 ntity of the ii: rise to electricity, a certain amount of heat vanishes,

 t"clrs of tte °^°^^^^ metals, has arranged the metallic molecules in 



a different way. This heat or force expends itseff in 

 producing the molecular change, and the result of the 

 new molecular arrangement is, that electrical pro- 

 perties are manifested instead of heat, because elec-

 viously alluded to as characterising the transformation 

 of the motion of masses into heat, or the motion of
