" Aristotle now introduees the distinetion between i^lara- 

 adai Kal p.€TafiaXX€Lv (" departing from type and ehanging 

 over ") and Xv^aOat. (" relapsing ") : as will be seen, the 

 result of the former process is that the embryo acquires a 

 characteristic opposite to that of the original movement (this 

 process has been clearly described already) ; the result of 

 the latter process (not so far described) is that the embryo 

 acquires a characteristic which belonged to one of its ancestors. 

 (The explanation of these two processes is given below at 

 768 b 15 ff.) 



*■ The semen, the movement derived from the male parent.
