within the heart it felf. And what can that be elle, but heat or 

 fpirits imprifonect in a tough vifcuous bloud; which it cannot 

 fo prefemly break through to get out: and yet can ftirre within 

 it, and lift it up ? 



The like of -which motion may be obferved, in the heaving 

 up, and finking down again of loofe mould thrown into a pit, 

 into which much ordure hath been emptied The fame caufe, of 

 heat in the earth, maketh mountains and fands to be caft up 

 in the very Tea: fb, in frying, when the pan is full of meat, the 

 bubbles rife and fall at the edges: treacle, and fuch ftrong com- 

 pounded fubftances; whiles they ferment, do life themfelves up 

 and fink down again , after the fame manner as the vipers 

 heart doth : as alfb do the bubbles of barm, and muft ofwiner 

 and fhort ends of lute firings baked in a juicy pie, will at the 

 opening of it move in fuch fort, as they who are ignorant ofthe 

 feat will think there arc magots in it : and a hot loaf, in which 

 quickfilver is encloied, will not onely move thus, but will alfb 

 leap about, and skip from one place to another, like the head

And that this is the true caufe of the hearts motion, appear- 

 cth evidently. Firft, becaufe this virtue of moving is in every 

 part of the heart, as you will plainly fee if you cut into feve- 

 rall pieces a heart, that confervdth its motion long after it is 

 out of the animals belly : for every piece will move; as Doctor 

 Harvey afTureth us by experience, and I my felf have often fcen, 

 upon occafion of making the great antidote, in which vipers 

 hearts is a principal! ingredient. Secondly, the fame is feen in 

 the auricles and the reft of the heart; whofe motions are feve- 

 rall; though fb near together, that they can hardly be diftin- 

 guifbed. Thirdly, Doctor Harvey fcemcth to affirm that the 

 bloud which is in the ears of the heart, hath fuch a motion 

 of it felf, precedent to the motion of the cars it is in : and that 

 this virtue remaincth in it fora little fpace after the ears arc 

 dead. Fourthly, in touching a heart which had newly left 

 moving, with his finger wetted with warm fpittlc, it began to 

 xnovc again , as tcftifying that heat and inoifturc made this 

 motion. Fifthly, if you touch the vipers heart over with vineger,
