Of Quadrupeds. 29 
But in a Mole, the fame Fibers which run by the length, 
being Indented,do alfo for a little way,each parcel obliquely 
run by the breadth of the Gut. Whereby they are able, 
without the help of fpiral Fibers, to narrow or fhorten the 
Gut of themfelves:and alfo to do both in the fame place. For 
by the Relaxation of the Fiber s,the fides of every Indenture, 
muft needs grow both wider and more diftant,and the Gut 
wider and more extended, at the fame time : and fo Vice 
verfa. Probably with this defign, That the Shells of 
feffs may make a more fafe tranfition, without raking 
againft the tender fides of the Guts. 
The Glands of the Guts are likewife of great Ufe. The 
Mucus which they fpew, ferves to make the Guts flip- 
pery, that the meat may the more eafily and fafely glide 
along. As alfo for another Ferment fuperinduc d to that 
of the Stomach, and fo a further coltiquation of the meat. 
With refpecl: to both which Ufes,the faid Glands, according 
to the Bore of the Guts, the hardnefs or foftnefs, cotirfenefs 
or colliquability of the meat, are more or lefs numerous 5 
as in the precedent Examples. 
And that this Mucus may be duly fupply'd, Nature full 
allows Blood-Veffels proportionable to the plenty of Glands. 
And hath taken care that the Veffels enter not the Guts on 
the fame fide on which the Glands are feated, but the oppo- 
fite : that having fpace enough to branch themfelves into 
the fmalleft capillary Tubes, before they reach the Glands, 
there may be the lefs danger, that any fincere Blood fhould 
with the Mucus make an Inundation into them. 
Through the fame Glands,as fo many little Springs,! con- 
ceive, That the Humours are either emunged, or precipi- 
tated, out of the Blood, in Purgation. For that one fo fmall 
a Pipe, as that of the Pancreas fhould bring fo great a quan- 
tity, is not at all probable. And the Glands being a vifible 
way, I know no reafon, wherefore we fhould have recourfe 
to any invifible one. 
Thus the fame Glands are a great means to prevent Fea- 
rers, and other ill effects of Cold by a Diarrhea. For when 
by a fuddain aftricliion of the Pores of the Skin, or other- 
wife, the ufual perfpiration is ftop'd s the redundant matter 
in the Blood, is often fafely difcharged, by the Glands, into 
the Guts. But if the matter be very {harp, or ruflieth upon
