Experiment XXIIL 
I, TMade hydraulic and hydroftatical Expe- 
*“* riments not only on the Arteries and 
Veins, but alfo on the inteftinal Tube; by 
affixing in like manner Tubes of different 
Heights to each end of them, while they 
were warm. 
2. I fixed a Tube to the Gullet of a Dog, 
and then poured in Water till the Stomach 
was fo full, that the Water in the Tube flood 
thirty fix Inches perpendicular Height above 
the Stomach 5 which Force burft it length- 
ways in its upper part near the PilomSy where 
it was but 7 + t Inches in Circumference : 
Yet no Water was impelled thro* the Pilorus 
with this Force, tho* in fome other like Ex- 
periments it has run thro* there into the Guts. 
Another Dog*s Stomach burft in the larger 
left part of it, when the Height of the Co- 
lumn of Water in the Tube was but thirty 
Inches. 
5. On meafuring the diftended Stomach of 
another Dog, I found its whole Surface equal 
to eighty fquare Inches, which multiplied into 
thirty fix, the Height of the Water in the 
N ' ^ Tube
