In the following paper it is proposed to consider in a few of their 

 many aspects, the nature of heat, the laws of its propagation, its 

 causes and its effects, noticing its correlation to the other forms of 

 energy, and some more or less important applications of what we 

 shall give some reasons for considering the true theory of heat to 

 some of the problems of Chemistry, Geology and Meteorology. Heat 

 being that in material bodies, which causes in us the sensation by 

 virtue of which we call bodies hot or cold, hotter or colder, it is 

 important at the outset to understand what that something in the 

 physical world is. Prof. Tait, the eminent Natural Philosopher, in 

 his valuable historical sketch of the Theories of Heat, says, that in 

 the physical world, besides the inevitable Time and Space, there are 

 but four elementary ideas, namely : — Matter, Force, Position and 

 Motion. This statement seems open to very serious objection. 

 Though time may from one point of view be regarded as one of the
