a Vegetable Juice, (hall either not ferment at all, or ia 
fuch a manner as is fcarce perceivable. 
In his laft Diflertation S.Saftguimti refumes theMatter of 
Chylification.He thinks theStomach has moft ofitsFament 
ditcharg d into it when its Membranes are diftended by the 
Food contained in them,becaufe the numerous fmallArteries 
fuffcr moftCompreflionat that time, and the Circulation of 
theBlood thro them is moft retarded 5 and fince the whole 
Mar% according to the Laws of Circulation, muft in a lit- 
tle time pafs thro the Stomach, there is no wonder Con- 
coftion (hould be fo foon finiftied.- 
It feems plain, the Aliment contained in the Stomach is 
attenuated by the Mixture of Ferments, and the Motion 
of its Membranes, and by the Contraftion and Preflureof 
its Fibres is protruded forwards, and when the Chylous 
Juice is perfefted by the Weight of the Stomach and Su- 
periour Vifcera, and by the Force of the Liver, confpiring 
with the Alternate Motion and Compreffion of the Dia- 
phragm, it is as it were by a Prefs fqueezed into the Guts. 
Before he concludes, our Author returns to his firft 
Head, and declares Acid and Alkali do not defer ve the 
Name of Principles, fince they arife from the Diffblution 
or Conjanftion of Bodies, and therefore are nomoreEle- 
m:ntary or Simple, than the other Chymical Principles, 
as Mr Boyle has largely prov'd in his Sceptical Chjmji.
