If fchou would'st know the mystic song 



Chaunted when the sphere was young, 



Aloft, abroad, the pasan swells, 



O wise man, hear'st thou half it tells ?

Of chemic matter, force and form, 



Of poles and powers, cold, wet, and warm*

Dissolving all that fixture is, 



Melts things that be to things that seem, 



And solid nature to a dream.'

 Im Kreis das All am Finger laufen liesse 

 Thm ziemt's, die Welt im Innern zu bewegen, 

 Natur in Sich, Sich in Natur zu hegen.' 



GOETHB.

 becomes the noblest attribute of man; the source of poetic genius, the
