" I venture to think the evidence now brought forward, however 

 imperfectly, is at least sufficient to justify the conclusion that there 

 is not a hair or a line, not a spot or a coloiir, for which there is not 

 a reason — which has not a purpose or a meaning in the economy of 

 Nature " — Lord Avebury.
