became joyned to fome pleafing or annoying fel 

 prefently, the heart is fenhbleofit i for the heart oeing joyned 

 to the braine by Straight and large nerves, full of ftrong fpirits 

 which afcend From the heart; it is impofT*bIe, but that it mufl 

 have fome communication with thole motions, vyhich paffe in 

 the braine : upon which the heart, or rather the fpirits about it, 

 is either dilated or comprefled. 



And thefe motions, may be either totally of one kind, or 

 moderated, and allayed by the mixture of its contrary : if 

 of the former fort; one of them wee call ;; , the other 

 griefe ; which doe continue about the heart (and peradven- 

 ture doe opprefTe it , if they bee in the utmoit extre- 

 mity ) without fending any due proportion of fpirits to 

 the braine 3 until! they lettlc a little, and grow more mode- 

 rate. 



Now, when thefe motions are moderate , they immediately 

 x fend up fome aboundance of fpirits to the braine : vyhich if they 

 be in a convenient proportion, they are by the braine thruft in- 

 to fuch nerves as are fit to receive thenrand fwelling them,they 

 give motion to the mufcles and tendons that are faftned to 

 them : and they doe move the whole body , or what part of it is 

 under command of thole nerves, that are thu filled and /welled 

 with fpirits by the braine. 



If the object was conformable to the living creature, then the 

 braine fendeth fpirits into fuch nerves , as carry the body to it : 

 but if otherwife, it caufeth amotionofaverfion or flight from 

 it. To the caufe of this latter, we give the name of Few : and 

 the other, that carrieth one to the purfuit of the object, we call 

 Hope* Anier 3 or AudMttj, is mixed of both thefe ; for it feek- 

 eth to avoide an evifl by embracing and overcomming ic : and 

 proceedeth out of abundance of fpirits. 



Now, if the proportion of fpirits fent frcm the heart, be too 

 great for the braine, it hindereth or perverteth the due opcrati- 

 9 . on both in man and beaft.
