MECHANISM OF NATURE 



will preserve its identity for a long time, subject 

 to changes of temperature and light and electricity 

 and cohesive strain, sound vibration and magnetic 

 penetration and numerous other vibrations perhaps 

 all at the same time. Still, in the vibration theory, 

 nothing holds the particles of glass together in this 

 mere line of a thread than just a set of vibrations 

 among a thousand. Shall it be said that our dull 

 ears can hear a sweet clear note among a thousand 

 noises ? Then shall a thousand ears distinguish the 

 same note, and if perhaps it be a dinner bell, a 

 thousand stomachs shall recognize the call ? 



So these same Ions that are outside of the mere 

 line of the Glass thread, alike to them that com- 

 pose the glass, why shall not they be affected in the 

 same synchrony ? 



There is without doubt a very radical difference 

 in the arrangements of the particles of solids and 

 of the same substance in a gaseous state. No syn- 

 chronic vibration in the molecules of gases makes 

 a difference in the confined gases or vapors in the 

 cylinder of Fig. A. 



All gases and all vapors and all mixtures of 

 them act the same. And density only determines 

 the degree of heat. That heat exerts a pressure, 

 this argues that there is a tendency of heat to pass 

 from one thing to another. That such tendency is 

 counteracted by gravity and hindered by the inter- 

 locking of particles in solids is proven in the con- 

 stitution of the earth. 



In every-day experience we know that it takes
