CHAP. V. 



SEARCH AFTER A CENTRAL LAW IN NATURAL 

 CHEMICAL CHANGES. 



AFTER what has been said in the pre- 

 vious chapter, little need be said in this 

 chapter and the next. 



What of the chemical properties of the 

 solar rays? Must we not regard their 

 presence as another argument in favour 

 of unity of law ? And is not their pre- 

 sence accounted for by unity of law? 

 There is only one answer to this ques- 

 tion, and this, as it seems, is in the 

 affirmative. 



Natural che- 

 mical actions 

 may be re- 

 ferred to the 

 law named 

 provisionally 

 the law of the 

 laboratory. 

 This law 

 affords the 

 only explana- 

 tion of these 

 actions. 

 These actions 

 may be taken 

 as another 

 argument 

 that the law 

 of the labora- 

 tory is the 

 law of nature.
