lying widiin the Guts, I faw a matter feemiog firft to coe- 
fill of Globules. Afterwards it appeared like little Guts 
within the great Guts: at leagtii it proved to be fnort 
threds, whofe one end was partly covered with the afore- 
faid veffels, and the other end was faft'ned to a Skin or 
Membrane, probably the fame with that called by the 
Anatomifts the inner-moft Coat of the Bowels. 
Fig. 7. AB. C. are the ends of the threddy fubftanca, 
otherVi^ife called theflime or woolly fobftance, which I 
fliall now name the inner-moft Mufcle of the Bowels, 
their Appearance (if the blood-vefleis be removedj is as 
mt\\Q Fig^iire':, the threds making the inward Mufcle of 
the bowels, if they be lookt on^ on one fide are as J, D^ E- 
r. the thicknefs of thefe threds, is lefs than a hair oi my 
head : they are very tender, and break upon the leaft 
touch ; I have fometimes thought that each of thefe 
threds confifted of fever al threds joyned together , or 
that every thred had a Membrane s for all of them feem 
to be very clofe linked together. 
This woolly fubftance (which I have defcribed) I con- 
ceive ma5> be of great ufe for the threds muft be longer, 
apd lye clofer together, and have little moifture betwixt 
them, whilfttheGut is empty and crumpled ; but when 
^ the gut is full and diftended with Viduals, the threds 
muft be ftiorter, and lye not fo clofe together as when the 
gut is contraded. By which means, the blood- veffels 
LaBeab and Lym.phaticks come more eafie to receive their 
^ liquors into them. For example, 
" Let us imagine that in the Fig. 8. J> B.'C is a gut cut 
■ acrofs as it is empty and fhrunk; that J, D. are the threds 
making the innermoft Mufcle of the Gut, now if the. 
got be full and ftretched to the widenefs of E, F G. the 
threds y/» D. will be contradred as E. FL not only be- 
cau(e they are clofe compacted together, as they lye 
mong one another, but alfo becaufe the blood-veflTels 
and other veffels running between them, keep them as 
B it
