ARISTOTLE'S BIOLOGY

 material composition to which attention is 

 being directed or which is the object of the 

 discussion, but the relation of such part to the

 common attributes; for his real interest leaps 

 to the group. And so he continues immediately

 course of exposition must be first to state the 

 attributes common to whole groups of animals, 

 and then to attempt to give their explanation."
