Knowledge, or Notice ; neither can it be caufed 

 by the Impulfe of any external Movent, unlefs it 

 be Heat. But how can the Spirit, agitated by 

 Heat, unguided by a vital Principle^ produce fuch 

 a regular reciprocal Motion? If that Site which 

 the Heart and its Fibres have in the Diajiole be 

 moft natural to them, (as it feems to be) why 

 doth it again contrad: it felf, and not reft in that 

 Pojfture ? If it be once contracted in a Syjiole by 

 the Influx of the Spirits, why, the Spirits conti- 

 nually flowing in without Let, doth it not al- 

 ways remain fo ? [for the Syjiole feems to refemble 

 the forcible Bending of a Spring, and the Dia/lole 

 its flying out again to its natural Site.] What 

 is the Spring and principal Efficient of this Re- 

 ciprocation ? What diredts and moderates the 

 Motions of the Spirits ? They being but ftupid 

 and fenfelefs Matter, cannot of themfelves con- 

 tinue any regular and conftant Motion, without 

 the Guidance and Regulation of fome intelligent 

 Being. You will fay. What Agent is it which 

 you would have to eflfed: this? The fenfitive 

 Soul it cannot be, becaufe that is indivifible ; 

 but the Heart when feparated wholly from the 

 Body . in fome Animals ^ continues ftill to pulfe 

 for a confiderable Time: Nay, when it hath quite 

 ceas'd, it may be brought to beat a-new by the 

 Application of warm Spittle, or by pricking it 

 gently with a Pin, or Needle. I anfwer, it may 

 be in thefe Inftances, the fcattering Spirits re- 

 maining in the Heart, may for a Time, being 

 agitated by the Heat, caufe thefe faint Pulfations> 

 tho' I fhould ratloer attribute them to a plajiick
