vade or diffolve it, the Stomach may extend, and the lower Guts may not. If there be one or more Stoppages in the upper Parts of the Guts, by great Quantities: of Phlegm gone off the Stomach in Maffes, the Stomach and Guts above may be extend-> ed, and the Pulfe abated, and the Steam may force upward, open the Valves, and make you vomit. And as foon as the Fluids are gone off in Steam from the. Excrements below the Stop, or any of the Excrements are discharged, which rarely happens in Quantity while there is a Stop, the Guts below will be lank, and as often as the. Steam above breaks through or forces by the Stop, or the Fluid fucceeds it, into the vacant Room in the Guts below, it causes a grumbling Noife as it paffes along. This Noife may happen at the Valve of the Pilorus or Colon, or in paffing by the folid Excrements below, but not in the fmall Guts, unless they be twisted or ftopped. Keeping the Stomach too much or too long diftended, ftretches the small Veffels that conftitute the Sides fo much, that filling or extending them with Blood, Juices, &c. will not contract the Stomach to the ufual Degree. Some have thought that when there is a Stop, or any other Cause, which makes the Stomach extend

too

great

too much, it may make it prefs the Artery behind it, and hinder a due Proportion of the Blood from defcending; but if the Stop be not near the Stomach, and there be no, great. Obstruction in the Paffage of the Steam, the fame Force which extends the Stomach, extends the Artery, and drives the Blood. But if there be an Obstruction near the Stomach, and the Steam iffue not out in due Proportion from the Stomach, or from the Guts below the Stop, the Blood will move flowlier, and the Preffure of the Atmosphere will prevail over the Strength of the Steam, and prefs a greater Share of the Blood into the inward Veffels; and though indeed the Blood will be less expanded, or in lefs Compass, yet perhaps See above, the Arteries will be more diftended than P. 112. when the Steam iffues brifkly, and the due Share of the Blood is outward. *

*This feems to be a more mechanical Account of the common Apoplexies than that from a Repletion of the Stomach, and its Preffure upon the Aorta.

Which open the Paffages in the Guts or their Valves.

SOM

COME Juices involuntarily fecreted or discharged out of fome peculiar Glands, out of the Stomach or Guts, or out of the Gall-Bladder, Pancreas, or perhaps from feveral of them jointly, or from feveral Parts for the feveral Valves which open the Mouths of the Glands in the Guts, as they defcend and let out the Juices and Steam which infinuate between the Plaits of the Valves, and make way for the reft, or that opens the Mouths of the Glands of the Valves, and makes them fecrete the Juice, and Steam which fwelled and extended them, and at once leffen their Magnitude, weaken their Force, and by the iffuing, Juice and Steam, repell their Infides from one another; and as the Juice and Steam iffues and empties, the Glands at once expand the Guts, fuffer them to extend or widen, and makes all their Sides fupple. During this Action, you feel a foft Tickling defcend all along down your lower Guts, and the Force of the Steam is em

ployed

ployed to discharge, and the Force of the Muscles which move voluntarily. The hard Excrements of every Creature, when they are discharged, have more or lefs of thefe Juices on their Outfides, and after they are difcharged, generally a small Quantity of thofe Juices follow; when the Excrements are discharged foft, those Juices are mixed and not fo vifible, tho' tis likely they are in greater Quantity. 'Tis faid fome People collect the Juices which are discharged after, and swim upon the Excrements of Cattle in May or June, and drink it to purge them, and that it does it effectually. All Creatures ftrain to discharge thofe Juices after the Excrements, and if a Man do not difcharge them, they will in Time occafion the Piles. I pretty much doubt whether it be the Excrements which remain in the Guts, or the volatile Juices and Salts discharged out of the Blood, which smell when they are difcharged by Stool. I think when one is coftive, and few Juices discharge out of the Blood, the Exerements fmell little or fcarce at all. In healthy Perfons, where there are no accidental Motives, nor Impediments, 'tis likely the Glands fecrete regularly, according to the Rules aforefaid, and when they

aro

are full, discharge almoft periodically. And as thofe Juices are fometimes difcharged other Ways, or obstructed in fecreting into or out of the Ducts or Glands, and are too few or too inactive, or meet with Phlegm or Obstructions, which entangle or blunt them, or defend and keep them off the Parts where they should act, fo on the other Hand, they fecrete inta and out of the Ducts, Veffels, or Glands too fast, in too great Quantity, or are too active, or there are other Juices in the Stomach or Guts which they excite, or the Mouths of the Glands are too open or too naked and defencelefs, or too much opened, or they fecrete too much, or too active Juice alfo, or the Steam is too ftrong, and hurries off the Excrements too fast, and sometimes the Juices wound the Glands, till they discharge even the Blood itself. The Juices may become too fharp or falt by the Straightness of the. Ureters, &c. which will not let a due Share of them pafs. And when the Blood is faturated with fuch Juices, the Glands will fecrete them into the Stomach and Guts. And in a Morning when your Stomach is lank, and you lie upon one Side, you will feel a burning, gnawing Heat on the under fide of your

Stomach,
