The Stomachs and Guts. 
M chap. 6. hcrc ’ W/ or tlle reaf on above-faid, defign’d by Nature to be 
a fecond Stomach. Whereas in an Ox or a Sheep, the meat 
having paflcd four fucceffive Concoctions, 'tis thence deli¬ 
vered to the Guts of a much finer fubftance ; and fo 
moveth fafe enough throuh a much fmaller Chanel 5 and 
faft enough, there being much lefs work here left, for the 
Ccecum to perform. 
The Contraction alfo of the Guts, or leifening of the 
Bore by feveral Necks, is of good ufe. As for inflance, in an 
Vrchan ox Cat ; ferving to flint the Tranfition of the meat, 
that it be not over quick, and dividing the Guts into fo 
many little Venters , in which the meat reflagnates for fome 
time, in order to its reception of as many repeated Con¬ 
coctions. Whereby alfo in thefe Animals the work of the 
C cecum, and therefore the making of it, feems fuperfeded. 
Moreover, the rations length of the Guts is obfervablc, 
. ccording to the cleannefs, or more fewer nutritive parts of 
the Food ; or its colhquability into Chyle. So in a Wee fie 
oxSquirel, that feeds much on Eggs, and Nuts, andfuch 
like fine and nutritive food, they are extream fhort. And m 
all Grofs eaters, longer than in other Quadrupeds. And 
thcreiore one reafon, why the Guts of a Sheep or Ox are 
fender, is, that they may be long. For were they Ihorter 
and wider, it would not be tantamount: For the food being 
Grafs, It is not fufficient that they Ihould hold enough: but 
aho neceffary, that they give a longer voyage to a fubftance 
io jejune, for a thorow folution and exuction of all its nu¬ 
tritive parts. Befides, that in a fmaller Channel, the faid 
parts will all along lie nearer to the Lacteal Veins, and fo 
more eafily be exprefs’d into them. 
j he Membranes of the Guts, have a general analogy in 
all Quadrupeds, and divers of their Ufes have been well 
aflignd. I fhall therefore only Note, That as the fpiral 
Fibers contract or purfe up the Bore of the Gut ; fo thofe 
that run by the length, draw it up ihorter, and fo dilate it. 
V hereby, as one part of the Gut may prefsthe meatfor- 
wk, °r as it were uifgorgeit, fo another gape to receive 
N -a t ie fame time. And in cafe one Gut fhould by ano¬ 
ther, or by fome Bowel, be opprefs’d,being by the faid Con- 
tiac ion in length removed a little out of its place 5 the free- 
uom of its motion, or any thing therein, will thereby be 
regam d. ; Suc
