ARISTOTLE 



which is to be built out of them, but they and not it 

 come first in the order of time and fact. Aristotle 

 sums this up by saying that what comes last in the 

 process comes first in " nature " (64^6 a 25). 



Μόριον, " part." 



The term Avhich occurs in the title of the treatise 

 and is traditionally rendered " part " includes more 

 than is normally included in the EngUsh " part of 

 the body." For instance, this Avould not normally 

 be applied to blood, but the term μόρίον is applied 

 by Aristotle to all the constituent substances of the 

 body as well as to the limbs and organs. For him, 

 blood is one of the {'wwi' μόρια. (648 a 2 ; see also 

 664 a 9j 690 a 8). A striking instance of the use of 

 μόριον in this sense is the phrase τά ομοιομίρη μόρια, 

 which are the subject of the next following note. 



Τά ομοιομβρη μόρια, " the uniform parts." 



Τά άνομοιομ^ρη μόρια, " the non-uniform parts." 



Aristotle's application of the term μόριον to both 

 these classes emphasizes the inclusiveness of its 

 meaning. As examples of the " uniform " parts he 

 mentions (647 b 10) blood, serum, lard, suet, marrow, 

 semen, bile, milk, flesh— these are soft and fluid"' 

 ones ; also bone, fish-spine, sineΛv, blood-vessel — 

 these are hard and sohd ones. Of " non-uniform " 

 parts he gives as examples (640 b 20) face, hand, foot. 



The relation of the " uniform " parts to the " non- 

 uniform " he describes as foUoAvs (647 b 22 foil.) :
