phagm lies behind between the Vertebra and L^r>«.v. Now how 
che z/Efsphagiu can lye thus behind, and yet have uch a Commu- 
nication with the Mouth, as to hinder the Larynx from commu- 
nicating with it, aifo is to me a very great doubt. 
He proceeds-, 1 The After a Arterial as very large, anddefti-

on the fore- 4 into the Lungs from Eating and Drinking, feeing there was no

* on - culty ftill remains } for how can Aliments be ingefted into the 
Mouth, and not pafs over by the Larynx, as is faid, before they 
enter the tA-f-phagus ; that would emply. that the zAfophagw lies 
before, and the Larynx behind, which would quite invert all the 
Tides- of the Occwomy of Animals: Since then the zAEfopagiu 
mull have in its defeent pafs’d in betwixt the Head and Lungs, 
and then penetrated the Diapbragma or otherwife, and after it had 
defeended a little, mult have turn’d afide and part: behind the 
Larynx , as the Arteria Iliac a do over the Pent Iliac a, which, 
tho’ by cutting off the Head, I could not obferve, yet is what 
Teems improbable to me ; becaufe then at the Deglutition, by the 
Preffure of the zsEfophagits on the one fide, and Vertebra of the 
Neck on the other, ever and anon would the Animal be oppreft 
with a difficulty of breathing when it took Food. 
He fays further : c To the outfide of thefe Catilages he found 
‘ another grow, which was faftned to them, but fo as to be ca-

1 which were implanted in it. ’Twas ftrong on both fides of the

‘ fide it was very Limber. This wanted about 2 \ Inches of com-

4 in breadth about r \ Inch about the middle, whofe Aperture
