APPLICATION OF FOREGOING PRINCIPLES. 63 



that With chickens, as with men, signs of contrivance 

 are indeed signs of contrivance, however quick, subtle, 

 and untraceable, the contrivance may be ? Again, I 

 have heard people argue that though the chicken, when 

 nearly hatched, had such a glimmering of sense that 

 it pecked the shell because it wanted to get out, yet 

 that it is not conceivable that, so long before it was 

 hatched, it should have had the sense to grow the horny 

 tip to its bill for use when wanted. This, at any rate, 

 they say, it must have grow T n, as the persons previously

 ever did or will, for, to say the least of it, many 

 thousands of years to come. It works with such absolute 

 certainty and so vast an experience, that it is utterly 

 incapable of following the operations of its own mind 

 — as accountants have been known to add up long 

 columns of pounds, shillings, and pence, running the

 the accountant, we say that the processes which his 

 mind goes through are so rapid and subtle as to elude 

 his own power of observation as well as ours. We do 

 not deny that his mind goes through processes of some 

 kind ; we very readily admit that it must do so, and
