MECHANISM OF NATURE 



cal motion. And this is a world-old mystery, and 

 the solution, "the identical life of every living iden- 

 tity/ ' is an equal mystery. Light cannot and does 

 not penetrate a solid substance as a direct move- 

 ment of Primary Spheres in plane layers, or in 

 straight columns. For the particles of solids are 

 interlocked in actual contact with one another. 

 (Proposition VI, B. 1.) And the density of a 

 substance has very little to do with its transpar- 

 ency, for the transparent glass is undoubtedly more 

 dense than is the opaque piece of cardboard. 



Again, the glass actually loses in transparency by 

 being heated to a high degree, which undoubtedly 

 enlarges the interstices between particles. 



The pure carbon of the diamond is transparent, 

 although its particles are a hundred-fold closer 

 together than the spongy charcoal, and that pecu- 

 liar arrangement of particles in crystallization is 

 the very essence of the transparency of carbon. 



There is, then, in the transparency of solids, an 

 undeniable element of individuality, and individu- 

 ality must needs be the result of a peculiar arrange- 

 ment of primary particles, when these particles are 

 in the last place, all alike and exactly similar. 



Roentgens X-rays penetrate a vacuum. They are 

 then a displacement of Spheres of void matter. 

 And these X-rays are propagated or projected 

 through solids which are not transparent. Yet, 

 they cannot be more rapid than hypothetical light- 

 waves. Heat that is projected through a rock-salt 

 lense cannot be a more rapid vibration than light
