SIXTH REPORT. 



(Vol. II., No. 1.) 



" A good practical naturalist must be a good observer ; and how many qualities 

 are required to make up a good observer ! Attention, patience, quickness to seize 

 separate facts, discrimination to keep them unconfused, readiness to combine them, 

 and rapidity and yet slowness of induction ; above all, perfect fidelity, which can be 

 seduced neither by the enticements of a favourite theory nor by the temptation to 

 see a little more than actually happens in some passing drama." — Essays, Bishop 

 Wilberforce, Vol. I.
