24 Tbe Stomachs and Guts. 
Graminivorous, yet comparatively have but little ones. For 
that a Horfe is made for labour, and both This and the Hare 
for quick and continu d motion : for which, the moft eafie 
Refpiration, and fo the freeft motion of the Diaphragme is 
very requifite 5 which yet could not be,(hould the Stomach 
lie big and cumberfome upon it, as in Sheep and Oxen it 
doth. For which caufe Nature hath here transfer d the 
greater part of the Aliment al Lugage into the C<xcum. 
The Neck of the Stomach, near the Gut, is commonly 
reflected backward, fo as to make an acute Angle with the 
Back of it. To the end, the extrufion of the prepared Ali- 
ment to the Gut, may be (tinted. And that the thiner part* 
which will more eafily wind about, may the better pais 
away, and leave the reft behind. Sometimes it hath three 
or four Flexures, as in Sheep and Oxen : for that the Gut 
being fo fmall with refpect to the Venter -,and with all fo very 
thin 3 it would, by too fudden or copious an irruption of 
the Aliment, be in danger of being burft. And for the 
fame reafons, the Stomach of a Pig, fo voraceous a Crea- 
ture, is alfo furniihed with a Stopple. 
The diftinct ufes of the Parts of the Stomach, are many 
of them the fame as of the Gulet. I (hall not therefore re- 
peat, but proceed to thofe particulars as remain to be ex- 
plicated. 
Andfirft, 'tis plain, in thofe thick Stomachs of an Ox or 
a Sheep, that the carneous Membranes are true Mufcules : 
which conducteth us more eafily to believe that of a man 
alfo Mufcular. 'Tis certain, that the Mufcules of the Abdo- 
men in lome Animals, as in Squirels, are thiner than thofe of 
a mans Stomach. . — 
Now the Nervous and Mufcular Parts joyntly fubferve 
to all the motions of the Stomach, which I reckon five, viz. 
Corrugation, Aftritlion, Undulation, Convulfion, and Voluntary 
Motion. 
Corrugation, is when there is a double motion of Con- 
traction, beginning from both the Orifices of the Stomach, 
and fo drawing it up into innumerable fmall Wrinkles. For 
the better expreflion of the Mucus out of the Glands of the 
inner Membrance. For a clofer comprehenfion of the Ali- 
ment, and immiflion of the faid Mucus or other fermenting 
Joyce, into it. And for the gradual expreffion of the colli- 
quated
