MIRACLES AND SPECIAL PROVIDENCES. 65 



judging of the order of Nature, our inquiries eventually 

 relate to the permanence of force. From Galileo to Newton, 

 from Newton to our own time, eager eyes have been scan 

 ning the heavens, and clear heads have been pondering the 

 phenomena of the solar system. The same eyes and minds 

 have been also observing, experimenting, and reflecting on 

 the action of gravity at the surface of the earth. Nothing 

 has occurred to indicate that the operation of the law has 

 for a moment been suspended ; nothing has ever intimated 

 that Nature has been crossed by spontaneous action, or 

 that a state of things at any time existed which could not 

 be rigorously deduced from the preceding state. Given the 

 distribution of matter and the forces in operation in the 

 time of Galileo, the competent mathematician of that day 

 could predict what is now occurring in our own. We cal 

 culate eclipses before they have occurred, and find them 

 true to the second. We determine the dates of those that 

 have occurred in the early times of history, and find calcu 

 lations and history at peace. Anomalies and perturba 

 tions in the planets have been over and over again observed, 

 but these, instead of demonstrating any inconstancy on the 

 part of natural law, have invariably been reduced to conse 

 quences of that law. Instead of referring the perturba 

 tions of Uranus to any interference on the part of the 

 Author of Nature with the law of gravitation, the question 

 which the astronomer proposed to himself was, &quot; How, in 

 accordance with this law, can the perturbation be pro 

 duced ? &quot; Guided by a principle, he was enabled to fix the 

 point of space in which, if a mass of matter were placed, 

 the observed perturbations would follow. We know the 

 result. The practical astronomer turned his telescope tow 

 ard the region which the intellect of the theoretic astrono 

 mer had already explored, and the planet now named 

 Neptune was found in its predicted place. A very re 

 spectable outcome, it will be admitted, of an impulse which
