‘The more we look into the question, whether by the light of 
analogy or the evidence of facts, the more are we convinced that 
lines of rigid demarcation (either between genera or species, 
though especially the former) do not anywhere, except through 
accident, exist. And hence it is that we ascend, by degrees, to a 
comprehension of that unity at which I have already glanced; 
and we are led to believe that, could the entire living panorama, 
in all its magnificence and breadth, be spread out before our 
eyes, with its long-lost links (of the past and present epochs) 
replaced, it would be found, from first to last, to be complete and 
continuous throughout,—a marvel of perfection, the work of a 
Master’s hand.’’—p. 179. 
It is a good thing to become acquainted with some of the older 
naturalists and their ways of working.
