THE GEE AT CENTER. 39 



We have thus seen that wherever the wonders of the 

 celestial spaces have been distinctly unfolded, the revolution 

 of satellites around planets, of planets around suns, of suns 

 around still greater suns, of systems around still greater 

 systems, of clusters around still greater clusters, is revealed 

 as an omniprevalent law. And seeing the complete unity of 

 plan and harmony of operations so far as we have gone see- 

 ing the affectionate co-relations which are exhibited between 

 molecules, and worlds, and systems, and all stellar congre- 

 gations, with all their included parts may we not prolong 

 the chain of analogy one link farther, and conclude that they 

 all, together with the myriads of similar creations which dwell 

 in depths of space which no optical power can ever penetrate, 

 owe the bond of unity w r hich connects them, and the har- 

 monial influence which wields them in their mighty courses, 

 to one grand Source of central power, whose attractions they 

 all implicitly obey, and from whose genial radiations all 

 receive their life 1 If the links of the analogical chain have 

 been found to closely adhere through all the labyrinths of 

 every realm of being whose existence may be verified by 

 other processes, who shall begin to distrust that chain for the 

 first time, after it has conducted us safely thus far 1 



Though the hypothesis of a common Pivot and Center of 

 gravity of the whole universe may not, in the nature of 

 things, be susceptible of an ocular or complete mathematical 

 demonstration, yet there is interior evidence I had almost 

 said even the evidence of intuition that it is true in some 

 form ; and I believe this idea is now extensively received as 

 an article of astronomical faith. 



Let no one suppose that amid these inconceivable dis- 

 tances and magnitudes, the fixed principles of reasoning lose 

 their validity and become untrustworthy. It is true that in
