ELECTRICITY. 





408. With respect also to conduction, light is opposed 

 to heat. Light is conducted by those very bodies, which 

 isolate heat, and isolated, not admitted to permeate or 

 absorbed, by those which conduct heat. The air conducts 

 light, isolates heat ; the metal, the earth conducts heat, 

 isolates light ; water holds a mediate relation towards 

 the two, yet towards light that of a conductor, because it 

 is deoxydizable. 



409. The conduction of light is likewise a process of 

 deoxydation, or a disintegration of matter. By the con- 

 duction of light the bodies are chemically analysed, and 

 finally resolve themselves into their principles ; such 



after all is the case with every glass and crystal. As p ? 

 the process of conduction of light may be called a process * 

 of deoxydation, so also may it be called a process of the / ^ 

 generation of colour. The conduction is an offuscation 

 of light, a colouring ; the deoxydation is a solution of the 

 material bonds, an elevation unto colour. 



2. Functions of the Air. 



ELECTRICITY. 



410. The air is the slightest combination of the 

 primary bodies, and stands in opposition with the two 

 other elements, as more solid combustions. In this an- 

 tagonism the air lays claim upon the other elements to 

 analyse them ; these, however, upon the air, to combine, 

 and undergo more vivid combustion. 



411. This antagonism is on a large scale an an- 

 tagonism of periphery and centre, like the primary 

 antagonism, by which planets and suns have withdrawn 

 from each other. The tension of air with the other 

 elements is called Electricity. The centroperipheric an- 

 tagonism between the sun and the planet, between light '". 

 and colour, represented in an elementary manner is 1 

 electricity. 



412. Sun and planet are electrically related to each 

 other, and the circumrotation of the latter may be viewed
