time in the open Air , do yet turn to meer Vinegar in 
the Stomach in a trice y and fo it is to be underftood of the 
fpeedy rotting of more fohd meats therein. 
I have confirmed this Do£trine with many other Argu- 
ments, which I refer too, to the Treatife it felf. 
Now becaufe meats that putrifie, whether of the Herb 
kind, or of Fifh or Flefh, do all therefore abound with vo-

Chyle of the filth of the groffer Excrements ; fo, after its

the Body by the Latlea ^ which are the only true mouths 
of the Body. 
That the Chyle firft loofes its Opacity and whitenefs, and 
becomes limpid in the blood Veins. 
That the limpid Serum is the old Chyle 5 which is not di-

That x}[iQ Ljmfha or Serum is ever a humour totally diftin 
from the red part of the blood, which turns grumo

genital humour. 
That, the caufe of fecreton is the Pulfe: its manner 1
