tratified rocks. I shall endeavour to show you 



that there is one kind <>t' evidence which is neutral, 

 which neither ln-lps evolution nor is inconsistent 

 with it. I shall then bring forward a second kind 

 , idence which indicates a strong probability in 

 ti\..ur <>t' evolution, but does not prove it; and, 

 la>;lv. I shall adduce a third kind of evidence 

 which, being as complete as any evidence which 

 \\- can hnpe to obtain upon such a subject, and 

 bring wholly and strikingly in favour of evolution, 

 may fairly be called demonstrative evidence of its 

 occurrence.
