EVIDENCE PROVING THE STATEMENT OF THE CASE 61 



Now let us see how completely this formula covers 

 all the facts. 



The gaseous molecule is, or tends to be, a spheroidal 

 object and has a free motion in mass. 



The liquid molecule is a spherical object and has 

 also a free motion in mass. 



Thus in the case of water the three gaseous 



o 



atoms (spheres) unite by overwrapping to form one 

 molecule (a sphere). 



The human mind is only able to grasp this one 

 conception to account for three spheres becoming one 

 sphere. And the scientific world, as well as our 

 " common sense," can only understand the motions 

 of fluid molecules (that is, in our illustration, liquid 

 or gaseous molecules) by the molecules being spheres. 1 



Press gases together with any amount of pressure 

 and submit them to great cold, they will become liquid, 

 but they will never combine. The diagram explains 

 that, in order to allow chemical combination, atoms 

 and molecules must expand in order to overwrap. 2 



Professor Dewar has liquefied oxygen gas and the 

 gases of which the air is composed. These liquids have 

 such an affinity for Ether that when they are quickly 

 evaporated to the gaseous condition the vessel holding 

 the liquid becomes so cold, that the gaseous molecules 

 of which the air consists give up their Ether to the 

 outside of the vessel, which in turn gives up Ether to the 

 liquid oxygen or air, in order to permit the liquid mole- 

 cules to become gaseous again, and so the free gaseous 

 air molecules collected on the outside of the receiver

 author's work " What is Heat ? " It is impossible to give the 

 details in this book.
