HEAT AND COLD. 



arrive at the solution of the problem. In weighing 

 the problem in this scale we need not give to heat or 

 cold any powers other than that observed by the school 

 boy on his way to and from school. Simply say that 

 heat tends to separate, and that cold tends to unite. We 

 need no other powers for heat and cold to explain 

 every trial our planet had from the gaseous period 

 to the present day. 



Now we will weigh the earth in the light of the 

 scale of heat and cold on the particles of matter, each 

 exerting the power as observed by the school boy. 



Our planet having cooled until all the waters and 

 other elastic properties were frozen up. This cooling 

 being brought about by the radiating of the heat into 

 space. The properties of matter solidifying and in 

 consequence, the reduction of the revolving power of 

 the earth on its axis. Reduction of revolving power 

 being a loss of power in propelling a foreign body that 

 tended to move toward the earth. Along with the re- 

 duction of revolving power, the freezing' up of the 

 elastic properties tended to reduce the reflecting power 

 of the sun. Reduction of the reflecting power of the 

 sun tended to reduce the power of reflection of a lifting 

 force onto a body that tended to fall toward the earth. 



In the face of the evidence, where had the earth 

 any chance of deterring the coming of a foreign body 

 from space onto the earth? If a foreign body had fell 

 onto the earth, what would be the result? Would a for- 

 eign body have generated heat and reduced the frozen 

 properties to air and water and other gaseous forms of
