IDENTICAL CHANGES 



A stream of void matter going in one direction 

 only, and encountering organized form, must un- 

 doubtedly produce a direct concentration of Mass, 

 which is evidently not the case. 



A vibratory current that is, a current reversing 

 its direction in a fixed time, might be considered, 

 but offers insurmountable difficulties. 



But an alternate current must disrupt atoms 

 always, even if there were only one Atom of five 

 spheres in a place by itself. But in that case 

 there would be no mechanical necessity of repro- 

 duction, for the sphere sunk into the cavity pro- 

 duced by the conjunction of three spheres would 

 pre-empt the space belonging to one sphere in a 

 moving plane layer, and in rising up to slip out 

 of the cavity it would not crowd any other sphere. 

 But Hydrogen, from many indications the first in 

 the series of atoms, and composed of five Primary 

 Spheres, is not found, in any evolution of Chem- 

 istry, by itself, but always in a molecule of two 

 atoms. While the particles of a gaseous substance 

 are apart from one another (Prop. IX, B. 1), yet 

 in some manner they are in conjunction, and we 

 cannot perceive a single atom of any kind. For 

 gases and vapors confined in vessels are amenable 

 to uniform laws of pressure and degrees of heat. 

 And, therefore, the void matter filling spaces, be- 

 tween the particles of gases and vapors, must par- 

 ticipate in any dismemberment and reproduction 

 of atoms in gases and vapors.
