III. Harmonies of Cosmical Rotation. 



The numerous indications of arithmetical, harmonic, and geometrical 

 progression which I have pointed out, are such as might have been an- 

 ticipated, if we regard the aether as a material medium of extreme elas- 

 ticity, by means of which all forms of material force are transmitted. 



Chladni's experiments gave abundant evidence of the tendency of 

 sonant vibrations to produce nodal and symmetrical aggregations of 

 material particles ; the drinking-glass experiments show that the tendency 

 is sometimes sufficient to overcome cohesive or other attractions which 

 oppose the symmetry ; Mossotti's hypothesis, that the radius of each par- 

 ticular material nucleus may be almost infinitesimal in comparison with 

 the radius of the sethereal atmosphere by which it is surrounded, makes 

 it comparatively easy to believe that even suns and planets may be in- 

 fluenced as to position, volume, mass, and motion, by harmonious vibra- 

 tions which are transmitted from particle to particle until they pervade 

 and control the whole mass. 



Rotation, as well as revolution, is one form of oscillation, and therefore 

 subject to the same general laws as the swing of pendulums, the undula- 

 tion of liquids, the sonant and luminous tremors of elastic solids, fluids, 

 and aethers. Some evidences of its being subject to rhythmical influences 

 may be found in the approximate agreement between the lengths of days 

 both in the Jovian and in the Telluric planetary belt. Other and more
