UNITY OF THE CREATIVE POWEE. 21 



to us by matter and motion, and signally by that great 

 force of gravitation on which these motions depend, is 

 another explicit declaration of the Unity pervading 

 the most remote parts of space. The accordances 

 here shown to exist, and in some cases even predicted, 

 are such as to exclude all idea of fortuitous relation. 

 A common cause of power can alone be brought to the 

 explanation of effects thus universal to our knowledge. 

 And other great forces also, as Heat, and Electri- 

 city in its different forms, concur severally as well as 

 conjointly in the same proof. Heat, as an agent, we 

 can scarcely dissever from light in our own solar sys- 

 tem ; and we have every reason to presume the relation 

 to be the same wherever light exists. 1 Of electricity, 

 whether under its condition of magnetic force or in 

 other forms, we must speak with less assurance ; yet 

 with strong presumption that this element, whatever 

 its intrinsic nature, is largely concerned in the pheno- 

 mena of universal Creation. Take a single fact in evi- 

 dence, and this from beyond the confines of our own 

 system. When we find iron as a constituent of so 

 many of the fixed stars, how can we justly suppose 

 that a metal so strongly characterised by its magnetic 

 properties on earth should be devoid of these relations 

 in any region of space however remote ? If this in- 

 ference be just, it involves collateral conclusions over 

 which we can scarcely impose a limit. The magnetic 

 force existing in these stellar worlds denotes the pre- 



1 Since this was written, the admirahle methods employed by Mr. 

 Higgens with the thermopile have given well-assured proofs of heat 

 derived from Sirius, Arcturus, and others of the fixed stars.
