OF BODIES, Ghap.XXXIV. 353 



fattened , the one in a greater bone , the other in a leffer ; and 

 there being leaft refinance on that part, where the boneKlc.'l 

 ier, and rnorcmoveable; the flvelling of the mufcle cannot 

 chnofe, but draw the little bone towards the great one;and by 

 confequence, move that little bone : and this is that, which 

 Philosophers ufiially call Voluntary motion for fince our know- 

 ledge remained! in the braine, whatfbever is done by know- 

 Jedge.muft be done by the braine ; and moft of what the brainc 

 workth for the common fervice of the living creature, proceed- 

 eth alfo from know ledge; that is/rom the motion of the fanfy, 

 VThich we have exprefled. 



This matter being thus far declared, wee may now enter w $ 

 upon the explication ofcertaine efteds ; which peradventure WH^M 

 might have challenged roome, in the precedent Chapter , but Jyhlch'are 1- 

 indeed, could not well be handled without fir/tfuppofing this "led natural! 

 lad diicourfe : and it is, what is meaned by thofe powers , that faculties., 

 are called naturall faculties : the which howfoever in their par- 

 ticulars they be manifold in a living creature , yet whenfbever 

 any of them is reiblved, it appeareth to be compounded of fbme 

 ofthefefive; to wit^the attractive, theretentive,thefecretive 

 the conco6tive,and the expulfive faculty. 



Of which, the attractive, the fecretive, andtheconcoftive 

 do not feeme to lielong unto the nerves , for although we may 

 conceive that the part of the animall doth turne it felfe towards 

 the thing which it attrafteth ; neverthelefle , that very turning 

 feemeth not to be done by vertue of the mufcles , and of the 

 nerves, but rather in a naturall way, as the motion ofthe heart 

 is performed, in fuch fort as we have formerly declared : as for 

 example, if the ttomack when it is greedy of meate , draweth 

 it felfe up towards the throate, it feemeth ratherto be a kind of 

 drynefTe and f warping, fuch as we fee in bladders or in leather 

 either by fire or by cold, which make them flirivell up and grow 

 hard 5 then that it is a true faculty ofthe living creature to leeke 

 after meate. 



-Nor need we extend our difcourfe any further about thefe 

 three faculties ; feeing that we ha,ve already declared in com- J\ie >; 

 rnon,hovv attraction, drying,and mixture ofactive bodies with tra aive and fc- 

 pafTiye one$,is per formed} which needethbut applying unto thefe cretive facul- 

 to explicate faUy their natures.'ts for exampte ; tio worke.
