the aether. If there are non -transparent bodies, they 

 can only be found in the earth-element, which, being 

 furthest removed from the aether, has perfected itself 

 independently, and they must indeed be wholly de- 

 oxydised. 



348. The co-illumination of bodies or their trans- 

 parency is an effort of deoxydation. Bodies that cannot 

 at ah 1 be deoxydised are non-transparent.

349. Transparency belongs only to those bodies which 

 have in themselves a twofold character. It will be 

 shown that the metals are absolutely identical matters, 



and therefore non-transparent. Thq metals are the only _.. 

 non-transparent bodies. Metaleity = non-transparency, /", g- _ 



350. The light falls upon a non-transparent only / : ^ <f' 

 through a transparent body, and thus one in which the 

 tension of light propagates itself. This co-illumination ' / V 

 of the matter placed in front of the non-transparent body 

 cannot cease to co-illuminate ; the tension must thus abide 



in it, and turn back from the non-transparent body, in/* y 

 a straight direction if the tension fell direct upon it, at a ^ / * 3 

 certain angle, if obliquely. This phenomenon is called (^^T? 

 Reflexion . / 7 6 



351. Reflexion is no repulsion of light, but only its 4*f/ 

 tension continued into the medium, in which the tension 



has been. 



352. A non-transparent body indicates nothing for 

 the tension of light but the limit of the co-illuminating 

 matter ; it does not at all operate itself upon the light, 

 it is as it were a void space. 



353. Transparent bodies also reflect partly, because 

 they are only relative aether, because they only co-illu- 

 minate, are not themselves tensed ; or because the basis 

 in all is the metal. Every other medium is, however, an 

 aether differently fixed ; in every one therefore the tension 

 has been changed ; every medium is thus a limit for the 

 tension, and therefore the transparent bodies also reflect. 

 Since the tension becomes altered, when it passes into
