MopioVf " part." 



The term M'hich occurs in the title of the treatise 

 and is traditionally rendered " part " includes more 

 than is normally included in the English " part of

 semen, bile, milk, flesh — these are soft and fluid** 

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

 these are hard and solid 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 follows (647 b 22 foil.) : 



" For the meaning of " fluid " and " solid " see below,
