608. Gneiss and mica-schist enter into a polar relation 

 with gravity, and that indeed as a Different to an Iden- 

 tical, as periphery to centre or as light to gravity. 



609. Now the falling granite had in part lost its quartz 

 and obtained a predominance of feldspar. Furthermore 

 as the water-globe was already greatly collapsed, the 

 crystals thus originated in larger drops, and occurred 

 .besides in water already stagnant or flowing. The schis- 

 tose gefiige must have emerged as well through the pre- 

 ponderance of the laminar felspar, as by the flowing of 

 water and the attraction of the granite- walls. This schis- 

 tose granite is gneiss. 



610. When the gneiss was thrown down the talc pre- 

 dominated in the water ; it now fell in the same manner 

 with less quartz and feldspar, and was deposited in a still 

 more schistose form than mica-schist. 



611. Granite, gneiss and mica-schist are the first that 

 together form a Whole, each factor whereof has been 

 evolved in an equally perfect manner. 



LAMINATION. 



612. By this active antagonism of granite to gneiss 

 and mica-schist the Lamination of the latter is determined. 

 Every particle of gneiss is attracted from the granite- 

 wall and placed in a definite direction, corresponding to 

 the polar operation of granite ; the particles of gneiss 

 already deposited attract the coming ones, and so on. 

 The parts of the gneiss and mica-schist are not deposited 

 upon the granite by virtue of their dead or inert gravity, 

 but by virtue of living polar attraction. They are not 

 therefore deposited in the depth of the primary valleys, 

 nor do they fill up the latter ; but they are attracted by 

 the granite-walls and deposited to a greater or less extent 

 like lamina? of crystallization, in large perpendicular 

 layers. 



613. By these two precipitations the primary valleys 

 were in part filled up, and partly narrowed by the polar 

 attraction of the walls. The primary vaUeys therefore 

 are no longer present upon the earth, unless everything-
