matrix, and it is'compoted of three tunicles ; the outwardmoft is common fiom the 
peritoneum, and is the thickeft; the middlemoft is proper to itfelf; and flefhy ; ‘the 
innermoftis from the dura meninx, and wrinkled, as alfo hairy like a piece of file: 
this is. continued with the tunicle of the afophagus, mouth, and lips, that nothing may 
be received in which is ungrateful to the ftomach: hence it is that; when ‘choler isin 
the ftomach, the tongue is bitter and yellow. Itis fpungy, andhas paflages like 
fhort fibres, from this inner furface to the outward, that the thinner chylus: may be 
the better detained. ‘The inmoft coat ferves chiefly for fenfe ; the middlemoft for 
the office of motion; and the third, that it might be as a covering for the whole. 
The ftomach has two orifices, and beth of them in the upper region thereof; the 
left is called os fomachi, the rightthe pylorus, or porter: the os ftomachi, or leftori- 
fice, has orbicular fibres, that, the meat and drink being once received within theca- 
pacity of the ftomach, it may, by a natural inftinét, exactly fhut up the mouth of the 
ftomach, left the fumes and heat fhould break out, which might not only gointo 
the brain and breed difeafes there, but alfo hinder concoétion. The right orifice ‘is 
of equal height with the other; left the meat and-drink fhould flip through before 
they are digelted. It is not wide like the former, becaufe it is to tranfmit the élabo- 
‘Fated chyle, which is done by the ftrength of the ftomach, in contracting itfelf. 
Wherefore the pylorus, belides its tranfverfé fibres, has a thick and’ compat cifdle, 
reprefenting the /phinéfer mufcle, that it might the moreeafily fhut and open. The 
itomach has arteries from the ramus caliacus, which accompany every vein, that 
blood may be fupplied from the heart for nourifhment of the part: it ‘has likewile 
“Many nerves; ‘viz. two in its orifice from the ftomach branches, which beihg pro- 
_ duced, after they have run back in the thorax, “and furnithed the lungs and pericar- 
‘dium, are covered with ftrong membranes. ‘Thefé fo crofs one another, that they 
» are carried obliquely, and without doubt with greater fafety. The right branch 
“compafits the fore and left part of the mouth of the ftomach ; the’ left branch, ‘the 
“binder and right part of the fame: from thefe branches of nerves are ‘fent down- 
“wards; tothe very bottom ; a branch goes from the left nerve, along the upper part 
‘of theftomach, to the pylorus, which it infolds with certain branches, and goes to 
“thehollowof the liver: other two nerves alfo go to the bottom of the’ ftomach, 
» from the branches which run along by the roots of the ribs. Hence it is, that, when, 
Bs 
_ itis that vomiting fo often fucceeds in‘ many difeafes, where there is a confent of 
the brain is hurt, the ftomach is fick, and falls a vomiting, as in a’ vertigo, bemicrania, 
© &eoalfo, whem the ftomach is affected, the head and brain are ill; or afflicted with 
"pain; and by reafon that the orifice of the ftomach is fo'compaffed with nerves, as 
if it were altogether made of nerves, it becomes of amoft exquifite fenfe; and hence
