100 THE BIOLOGY OP DAILY LIFE. 



every human being will be found as strictly in ac- 

 cordance with laws, i.e., as capable as being grouped 

 and classified and calculated as, let us say, the 

 apparently erratic course of a comet ; and the greater 

 and lesser lights which rule the day or night of 

 human discovery in the material and spiritual worlds, 

 perceptible or non-perceptible to merely bodily senses 

 (represented by the dayside and nightside of Nature), 

 will be found at least as reducible to calculation as 

 the courses of the sun and moon are now by the 

 astronomer. 



" Unborn the hands but born they are to be," 

 which shall reduce the spiritual universe into as con- 

 spicuous order as we can now behold in the material 

 universe, by the labours of Newton and his followers 

 on the same and kindred branches of the great tree of 

 universal science. 



Be all this as it may, a connection can be distinctly 

 traced between the training and the discovery. It 

 may seem to the discoverer himself as a thing he can 

 come upon by chance, but the path on which he 

 was treading when he met with that thing the 

 luminous conception or pregnant Fact which constituted 

 the Discovery was not the result of Chance. We may 

 safely assume that on no other path would he have 

 come upon it, or at all events have seen it in the same 

 relation ; the object, if seen at all, would have been 

 seen from a different point of view. In other words, 

 that particular discovery would not have been made. 



In the case of Faraday,* we can distinctly trace a

 tion, telling him he would there learn how to make a most
