VII. of this 2d Vol. where it was found by 
i a mercurial Gage fixed to the Nofe of a large 
I Pair of Smith’s Bellows, that the moft forci- 
ble blaft of them will fcarcely raife Mercury 
two Inches high in the Gage: And fincefucli 
a blaft of Wind is manifeftly much greater 
chan the moft forcible puft of Wind, which 
is belched out of a much diftended Stomach y 
\is hence evident that the Stomach even in 
that much diftended Cafe does not comprels 
what is contained in it with near that Force, 
j . 4. If we fuppofe the Surface of a full Sto- 
if mach to be equal to eighty (quare Inches, and 
! that its Contents are comprellcd by the Adion 
of it, together with that of the Diaphragm 
and Mufcles of the Abdomen^ with a Force e* 
qual CO one Inch depth, then the whole Pref. 
fore on its Contents will be equal to thirty 
nine Pounds, which is nearly the Weight of 
eighty cubic Inches of Mercury : But as this 
feems to be too great a Force by comparing 
the Velocity with which Wind rulhcs out of 
Bellows, when its Force is fufficient to raife 
Mercury an Inch in the Gage, fo I believe 
half that Force, viz. about twenty Pound^ 
would come nearer to the Preffure on the Ali- 
ments of a full Stomach. . . :
