that lifeconfifteth in heat and humidiivjand that the/e two ;oy- 

 ned together, doc make a thing great : and wee may conclude 

 thatotnecefllty the motion which is moft lively,, mutt havea 

 great, full, and large ftroake; like the even rolling waves of a 

 wide and imooth lea; and not too quick or fmart, like the brea- 

 ches ofa narrow Fr<mw,agitated by tempeftuous windes.From 

 this, other motions may vary either by excefle,orby deficiency: 

 the firfl maketh the (Ireake bcccme iinart, violent and rhfcke : 

 the other fiackeneth it, and maketh it grow little., flow^veake, 

 and thinnCj or ieldome. 



And ifwelookeinto the motions ofour heart, wee ftiaJl fee 

 thele three differences of them follow three feverall chiefe pal- 

 (ions.The firfl, followeth thepaffion of joy : theforond^hepaf- 

 fion of anger : and the third,thepaffion of griefe. Ncrnecde we 

 lookeany further into the caufes of the leverall motions ; for 

 we fee that joy and griefe , following the ftroake of fenie.the 

 one of them muft confilt in an oyly dilatation: that is^the fpirirt 

 about the heart mult be dilated by a gentle, large, great, and 

 fwcet motion,in a ir.oderation betsveen velocity and flownefle : 

 the other contrariwife, following the ftroak of fenfe inpaine, as 

 thefirftdidin pleafure, mult contra^ the fpints; and conll- 

 quently make thtir motion or ftroak become littie.and deficient 

 nrom all the properties we have above fet down. 



As fcr anger,the motion following that palJion, is, when the 

 aboundance of fpirits in the heart ha. little checked by the con- 

 trary ftroak of fenfe, but prefently ovrccomrmt'i that oppofi- 

 tion : and then 3 as we fee a hindered water, or a man, that fiicf- 

 dainly or forcibly break through what withtiood their motion, 

 go en with a greater violence then they did, and as it were pre- 

 cipitately : fo the heart , having overcome the contraction, 

 which the fenfe made in it, diatethit felfewichafuiy, and 

 maketh its motion imart and vehement .Whence alfb it follow- 

 eth, that the fpirits grow hotter then they were:and according- 

 ly, it is often feen,tnat in the fcouldmg of a woman , and in the 

 irritation of a dog 5 il ex er now & then, one thwart them,and in- 

 terpofe a litt.eoppofition, their rury will be fo fliarpened and 

 heightened , that the woman will be tranfported beyond all li- 

 mits of reafcn, and the dog will be made maJ with nothing 

 cJfc done to him, but angring him at convenient time* : and
