§ J. A Natomifts ift their Defcription of Man's Body, 
\ £\ tho' they fometimes Make mention of the 
Motion of the Stomach, (as in Vomiting and in convey- 
ing the Meat that is Digefled in the Stomach into the 
Inteftines) yet giving no particular Defcription of it 
from the Teftimony of Sight, I hope it will be no ways 
impertinent in me to give an Account of it, as it ap- 
peared to me in the Difledion of a Dog, in July^ 
§ z. In this Dog I obferved that the Periftahick Mo- 
tion of the Guts was continued thro' the Stomach ; the 
Pylorus (that ufually appears, after opening the Dog, as 
high as the Diaphragm) being in every waving brought 
below the very Bottom of the Stomach, I could mani- 
feftly obferve a Conftridion in the middle of the Sto- 
mach, at every Motion Downward, pafiing it in fo as 
to be able to comprefs what was contained in iis Gavity. 
And thefe Motions were as regular and orderly as ever I 
faw it in the Guts ; and appeared for a long time toge- 
ther,- (b that I could the more diligently make my Ob- 
fcrvations. 
^3.1 have feen the Motion of the Stomach in Two 
or Three that I have difleded fince, fo that one may 
ftfely conclude it holds true in all. 
^ 4. I fuppofe the Reafon that it appear'd Co mani- 
feftly and long in the Firft Dog, wasbecaufe his Stomach 
being extreamly full, put the Fibres upon fome Stretch,- 
fo that they (as all fuch Bodies do) endeavoured by their 
Motion to reftore themfelves to their former Pofition.
