.. The inteftines, or guts, begin at the pylorus, and end in the anus’ or fundament. 
They are called inteftina, or inwards, becaufe they are in the inmoft feat.of the body. 
They are of a round figure, that they might the better contain the nourifhment; of 
4 membranous fubftance, the better to have conftriétion and dilatation; and indeed 
their fubftance is almoft the fame with the ftomach, having three coats, one com- 
mon and external, being bred immediately from the menfenterium, but mediately 
from the peritoneum. The fecond, which is the middlemoft, is proper, being mem- 
branous, ftrong, and furnithed with flefhy fibres, The third, which is the inner- 
moit, is alfo proper, nervous, and lined with a crufty fubftance, framed of the ex- 
crements of the third concoction of the guts, glazed as it were with a mucys or 
ophlegmatic fubftance, bred in the firft concoétion, by which excoriation is not only 
hindered, when fharp humours pafs through the guts, but alfo by its affiftance the 
expulfion of the foeces is furthered... This internal membrane has fuch a crufty 
fubftance, that the mouths. of the meferaic veins might not be ftopped; and thac 
neither they nor the coat itfelf might be made callous by the continual thoroughfare 
of the chyle. The fibres of the internal membrane of the fmall guts are oblique, 
‘but of the external coat tranfverfe; becaufe thefe are appointed for the retention 
sand expulfion of the chyle: but, in the thick guts, the inner coat has tranfverfe 
fibres, the outward has oblique and ftraight, becaufe they are appointed for the ex- 
Pulfion of. the excrements: the inner ‘membrane alfo of the {mall guts, is full of 
wrinkles to ftay the chylus from paffing too foon. As to the length of the-inteftines, 
they are in general fix times, as long as the whole body: it is wonderful that the

they-are not above a {pan diftant from the centre, They have a motion, which is
