 And where obvious utility does result, the only 

 connecting Bond which can be conceived as cap- 

 able of maintaining the Internal Correlations in 

 harmony with the External Correlations, is the 

 Bond of Creative Will giving to Organic Forces 

 a foreseen direction. It is, in short, precisely the 

 same bond which in all mechanism produces har- 

 mony of Structure with intended Function. 



Hence it is that scientific men in seeking expres- 

 sion for the ultimate ideas arrived at in the course 

 of Physical research, find themselves compelled 

 to borrow the language of Mechanical Invention. 

 There is no other language which conveys an im- 

 pression of the facts, or of the tie by which the 

 facts are connected with each other. In the first 

 chapter of this work I have had occasion to point 

 out how true this is of Mr Darwin's description of 

 the Orchids, and of the curious functions of their 

 structure. The correlations there are all external. 

 But the same result appears in every other depart- 

 ment of Science. In a remarkable paper on the 

 " Constitution of the Universe," Professor Tyndall 

 has occasion to speak of the non-luminous rays
