been underftood 5 then it is as certain, that 
the juices of vegetables and animals do not 
ferment in a healthy ftate, as it is, that they 
do not at the fame time coalefce and difu-

larger fenfe, for any the fmalieft to the grea- 
teft degree of inteftine motion of the par- 
ticles of a fluid, then all vegetable and anb 
mal fluids are in a natural ftate, in fome 
degree of ferment, for they abound both with 
elaftick and fulphureous particles ; And it 
may with as much reafon be argued, that 
there is no degree of warmth in animals 
and vegetables, bccaufe a great degree of 
heat will caufe a folution of continuity, as 
to fay, there is no degree of ferment in the 
fluids of thofe bodies, becaufe a great repel- 
ling degree of ferment will moft certainly 
diffolve them.
