cous Coat. This is generally allowed to confift of 
the capillary Extremities, or rather Roots of the Lac- 
teals , and the excretory Duffs of the Glands, which 
together form thefe Villi that are feen in if. Among 
thefe, fuitable to Analogy in all other Parts of the 
Body, the Papilla Pyramidales, or Extremities of 
the Nerves , are lodg’d under the Cuticula of the 
nervous Coat, for the Ufes of Senfation, fo necelfary 
for the Purpofes of Nature, in this very fenfiblePart 
the Infide of the Guts, which is known to be fo 
quickly and necelfarily affected by the Qualities of 
their Contents. 
The proper Nerves of the firft or outward Coat, 
are thofe of the Peritoneum, of which it is a Part, 
arifing from the Medulla Spinalis of the Loins and 
Os Sacrum: Whereas the Nerves proper to the 
Guts , are of the Par Vagum , and menfenteric 
Plexus : Therefore as there is no Communication 
of Nerves between this external Coat or Covering, 
and the proper Subltance of the Inteftines them- 
felves, a Stimulus aiding upon this external Coat 
only, would not affeft the Guts fo as to excite any 
confiderable Degree, either of Senfation or Motion in 
them. 
Again the proper Nerves of the Interims , whofe 
Origin, Difpolition, and Situation have been already 
defcribed, terminate either in the mufcular contractile 
Fibres of the Coat immediately above them, or car- 
ry their Extremities to the Infide, where they termi- 
nate under the Cuticula , for the ufe of Senfation : 
fo that a Stimulus on the outfide of the InteJHnes, 
befides the Difficulty of palling through the two exter- 
nal Coats, before it could reach the proper Nerves
