proportionable to what they wrought firft in the outward fen- 

 ie^from whence,they were conveyed to the brainc ; for the fen- 

 Ccs (chat is the nerves ) and the StftiimjMcibmJiwingbQth of 

 them their origine from the very fubfiancc of the braine , and 

 differing only in degrees of purity and refinement, the fame ob- 

 ject mult needs worke like effeds in both, compreflfng or diJa- 

 ting them proportionably to one another :which compreffion or 

 dilatation, is not paine or p!eafure,,as it is in the outward fenfe ; 

 but as it is reported to the heart . and that,being the feat of all 

 paines or pJea/ures wrought in other parts,and that (as it were) 

 dyeth them into thole qualities, is not capable of feeling either 

 it felfe : Co that the ftrokes of any little fimilitudes upon the fan- 

 tafy,do make only compreflfions or dilatations there, not paines 

 or pleasures. 



Now their bodies or fimilitudes ,if they be reverberated from 5 

 the fantafy or (cftum Lucidum. upon the littl roots of the nerves Of Paffiom 

 of the fixt conple,which go to the heart, they muft needs worke 

 there a proportionable impreffion to what they wrought upon 

 t he fanf y, either compreffing or dilating it - t and the heart being 

 extremely pafsive, by reafbn of its exceeding tendernefleand 

 heat , cannot choofe but change its moticaat the leaf* in part,if 

 not in whole:and this with reJation to twocaufesrthe one difpo- 

 fition of the heart it ielf ^the other,the vehemency of the ftroak. 



This change of motion and different beating ef the heat , is 

 that which properly is called pafsion : and is ever accompaincd 

 with pleafiire or with grief, according to the nature of the im- 

 prefsion, that either contraiteth or diiateth the heart and the 

 ip-rits aboutit : andisdifcovered by the beating of the arteries 

 and of the pulfe. Conformable whercunto,Phyfitians do tell us, 

 that every pafsion hath a diftinft pulfe. 



Thefepulfes are divided in common, by aboundance, or by $. 

 want of fpirirs : yet in both kinds, they may have common dif- of (eTcrali 

 ferences ; for in aboundance , the pulfe may be quick or flow, pU8 caufl 

 regular or irre^ular^uall or unequalltand the like may happen y paffions. 

 in defeat of ipirits ; accordingly to the motions of the heart, 

 which are their caufcs. Agame, the objeftbybein^prefent or 

 further otf, makcth the iiroak ^rtrater or lefler : and according- 

 ly vaneth the motion of the heart. 



let us then call to mind , how wee have formerly declared,
