CHAPTER XXV 



DANGERS TO THE HUMAN ORGANISM. 



Before closing this work, it would be well to con- 

 sider the action of heat and cold in the light of their 

 respective powers on the properties of matter, and 

 weigh the effects on the human organism, and show the 

 dangers to be encountered by abusing the true law of 

 the forces. 



When you place your hand into a basin of cold 

 water the cold w r ater causes the properties of matter 

 making up your hand to contract. The contraction in 

 the particles causes the sensation of cold. It is the 

 union of particles in the hand. Change the hand into 

 a basin of hot water and the heat expands the proper- 

 ties making up the hand. The expanding movement 

 is recognizable as heat. You can immediately distin- 

 guish between heat and cold, because the particles of 

 body change course of movement. 



Now, if you are exposed to cold so as to freeze a 

 member of your body, the frozen member should not be 

 exposed to heat in any quantity. Why? Well, we shall 

 explain the dangers from the foundation of the forces. 

 Heat and cold always, when present in quantities, tend 

 to demarkate lines of action of their respective forces; 

 herein lies the danger. When exposed to heat in quan- 

 tity from without, it forms a zone of gravity between it
