It has been said, that " the material theory 

 contains an inherent vice, by assuming the ex- 

 istence of a body, which has never been obtained 

 in the separate form." But if caloric do not 

 exist in a separate state while passing through a 

 vacuum, all our reasonings about it are fallacious 

 and unintelligible. Nor is it possible to explain 

 in a simple and satisfactory manner, any single 

 one of the phenomena ascribed to it by all par- 

 ties, in accordance with the hypothesis that it is 

 identical with motion, which is manifestly not 

 an agent, but merely some body in the act of 

 moving, and always implies the existence of a 

 mover. 



If the vibratory theory were true, caloric ought 

 to be generated by all impulses which throw the 

 particles of bodies into a state of violent agitation. 

 But such is not the fact ; for if the atmosphere, 

 the ocean, and the solid strata of the earth, were 

 kept in a state of perpetual tremor, their tempe- 

 rature w r ould not be materially altered. The ad- 

 vocates of the immaterial theory have never ex- 

 plained what causes bodies to vibrate ; nor what 



touch, and then think upon. And he adds that all impressions on 

 the senses are resolvable into touch. But there is nothing in na- 

 ture which operates so powerfully on the sense of touch as caloric. 



" When Bishop Berkley said there was no matter, 

 And proved it 'twas no matter what he said." 



And when men say that caloric is not matter, they reject the evi- 

 dence of their senses, subvert the foundation of all knowledge, 

 and pave the way to universal scepticism.
