Aliment atry Parts, which it firft communicates 

 a Motion to, improved by the Heat of the Sto- 

 mach, the Saliva muft neceffarily act upon 

 the groffer Parts. For the inteftine Motion, 

 which is excited in the Mafs, does not give the 

 Particles, which are fermented, the lame Ten- 

 dency, but what ij fb various and confus'd, that 

 they muft inevitably ftrike not only one a- 

 gainft another, but againft thofe which are 

 more grofs, fo as to attenuate them, fometimes 

 by a Collifion, which ftrikes off fmaller Par- 

 ticles from the larger Parts ; fbmetimes by a 

 Compreflion, when the Particles which are in 

 Motion, happen to ftrike directly againft any 

 groffer Part, on every fide of it, fbmetimes 

 by a kind of Explofion. For without doubt 

 the Saliva, which is fluid, infmuates it felf in- 

 to the Interftices of the more craft Parts of 

 the Aliment, and whatever is agitated and ex- 

 panded in thofe Interftices, requiring a larger 

 fpace for the Freedom of its Motion, and of- 

 fering a Violence to every thing that oppoles 

 its Tendency, will, like Gun-powder included 

 in a Shell, force its way out, and tear to 

 pieces that Matter, which does endeavour to con- 

 fine it. 



Thus the groffer Parts are broken and di- 

 vided , until they are at laft fo far attenua- 

 ted as to mix more equally with the Fluid, 

 and with them to make one Pulp or Chylous 

 Mafs. And although I do not apprehend 

 bow the Stomach fhould by its reciprocal Mo- 

 tions in Infpiration and Expiration, be able to 

 break and attenuate any Matter, that will not be 

 foftned and diffolved by Agitation in a Liquid $ 

 yet it is certain that thefe Motions, caufed by
