A TREATISE 



dingly one branch of this nerve, reacheth to the heart; cot on- 

 ly to the Pericardium, as Galen thought, but even to the very 

 fub/tence of the heart it Cdf, as later Anatomies have difcover- 

 ed ; by which we plainly fee how the motion which the ienfes 

 doe make in the Sfccultim, may be derived dovvne to -the 

 hearr. 



Now therefore let us confider , what effects the motions Co 

 ^ . conveyed from the braine, will worke in the heart. Firiire- 

 leffurT. * membrbg how all that moveth the heart, is either paine or 

 pleafure (though we doe not ale to call it painc,but grief, when 

 the evill of ienie moveth us only by memory , and not by being 

 a&ually in the fenfe) and theia calling to minde, hovv paine (as 

 Naturalises teach us Jconfifkth in ibme divifion of a nerve, 

 (which they call Solntiocontixui: and muft be in a nerve;. for 

 thatnofoliitioncanbetheeauleof paine, without fenfe, nor 

 fenfe be without nerves; and therefore t.his folution muft needs, 

 be in nerves, to have ic prove painfii II,) wemay conclude, 'that 

 the effect which we call.pame.is nothing die but a comprelTion: 

 for although this fclution of continuity may ieeme to DC a diia- 

 tationj yet in truth, it is a compreflTion jn the part where the 

 evill is, which happeneth unto it in the lame manner as wee 

 fiiewed (when welpoke of the motion ofrertrtution )it doth to 

 ftifte bodies, that by violence are compretfed and drawne into 

 a lefTe capacious figure, then their nature affedteth, and returne 

 into their owrieftate, asfoonasthc maltring violence Jeavcth 

 them a,t liberty. 



P Jeafure therefore, muft be contrary to this, and confift in 9, 

 moderate dilatation; for an immoderate one, would caufe a 

 compreflion in fbme adherent parts ; and there would become 

 paine. And conformable to this, we experience, that generally 

 they arc hard things which breed paine unto us ; and that thcfc 

 which breed pleafure, are oy ly .and fof t > as meates, and odours, 

 which are Iweet to the tafteand fineiljand fbft fubftances, which

 tl-nfi ve and painfull; fo that from the extremity of pleasure, one 

 fafitrethpfe/ently upon the confines of paine. 



Now then let us cenfider, how the little fimilitndes of bo- 

 dies, whieh from without dee come into the /antafy, muft of
