it were bound up : for if they were feparated from one 
another, then would the grofler parts of the Excrements 
get among them, as often as the Bowels are extended. 
Now the threds not being crowded (o much when the guts 
are ftretched, the Chyle enters more eafily into the veffels 
lying among them,and afterwards upon every Contracti- 
on of the guts (becaufe then the threds are fqueezed to- 
gether) is conveyed into the body. 
I faid before that the threds which make the inner- 
moft Mufcle of the Bowels, lye with their one end in 
the hollow of the Bowels , which end is for the moft 
part covered with blood-veflels and other veffels. Their 
other end is fattened to a Skin or Membrane which 
probably is taken by Anatomifts for the Innermoft 
Coat of ^e Bowels, as in the line D. £. 7- 
be feen. In this Membrane I difcovered many Glo- 
bules of fat, which in fome places lay clofe and crow- 
ded together, and therefore appeared in different fhapes. 
In other places lay fome fat Particles , at a diftance 
from the reft, thefe all inclined to an oval ihape as 
Fig^ 9. In another place a little diftant lay ovallifh 
Particles in a right line, as Fig. 10. In another place 
the Particles lay fo thick together, that they crowded 
one another, and appeared as in Fig* 1 1.
