MECHANISM OF NATURE 



off all the Universe would soon be of a uniform 

 temperature. And organized substance is influ- 

 enced by heat only because of its organization; 

 therefore, a real understanding of that organiza- 

 tion alone can confer a full knowledge of the real 

 nature of heat. 



All life is manifested under a degree of heat ; we 

 can conceive of no life under an absolute zero. 



The changes produced, in material around us, 

 by heat are of an almost endless variety; and be- 

 cause of the interlocking of solids and the pecu- 

 liarity of form of every substance, the passing of 

 heat from one body to another is often obscured 

 and seemingly doubtful. 



Friction, electricity and chemical combination 

 produce heat ; we get a notion that they manufac- 

 ture it. But all three produce light also and other 

 forces. And if we can look close enough we will 

 probably find that the bringing together of par- 

 ticles, which these forces accomplish incidentally, 

 is the origin of the heat observed. 



As compared with Gravity and Inertia, heat is 

 not so strictly related to Mass. For although it 

 takes a certain invariable amount of heat to raise 

 a given Mass of any one substance through one 

 degree of heat, the same amount of heat will not 

 raise an equal Mass of another different substance 

 through just one degree of heat. 



It will take more heat to raise a pound of gran- 

 ite through one degree than is required to raise a 

 pound of iron through one degree.
