t ' The sense, though perhaps not the syntax, of the 

 following sentence is clear. The contrast is between (a) 

 causes c'f dvdyKTjs {i.e., mechanical causes, viz., the " motive " 

 and " material " causes, the operation of which in the pro- 

 duction of male and female individuals Aristotle describes in 

 detail in Bk. IV. 765 b 5—766 b 26 ; cf. 767 a 36—768 b 36) ; 

 and (6) the " final " cause, the better purpose or " end " for 

 the sake of which male and female individuals are produced.
