Part.

The Stomach can be diftended to hold near a Gallon, and contracted into the Space of a Pint. When the Steam in the Stomach or any part of the Guts is weak or abated, fo that the outward Preffure prevails, the greater Share of the Blood is forced into the inward Parts, and the Veffels and Glands in the Sides of the Stomach, or that Part of the Guts, are fuffered within, and forced from without, to admit a greater Quantity of Blood and Juices; fo when the Meat, &c. is discharged from the Stomach, and the Steam abated, the Air from without forces the Juices to fecrete out of the Blood into the Glands of the Stomach, and filling the Veffels and Glands contracts the Stomach, and leffens its inward Capacity by Degrees, as the inward Force abates, and its Arteries, Veins, Glands, &c. fill. When the Stomach is contracted, and one takes Meat and Drink cold, the Juices iffue, let the Stomach extend, and the Cold condenfes the Steam in the Guts, and makes Room for it. When the Meat and Drink is taken warm, they do. not condense the Steam in the Guts, but extend the Rind of the lower Belly to make Way, and gives one a greater Sense of Fulness with a lefs Quantity. When one

or, &c. one lofes one's Appetite: But if
one drink fome very cold Liquor, it con-
denfes the Steam, and makes the Stomach
less diftended or more empty, and the
Guts make more Room for it, than be-
fore one drank the Liquor, and presently
after one recovers one's Appetite. When
the Stomach is diftended with Steam,
and one takes Meat and Drink, it con-
denfes the Steam, and the Blood and
Juices prefs into the Sides of the Stomach,
contract them, and make them press close
about the Fluids, &c. As the Fluids, &c.

Steam can extend the Sides beyond the

Creatures after they are opened. When
one eats too foon before the last Food be
discharged, the Steam abated, and the
Stomach contracted, and the Glands, &c.

will be mixed with the old, and if it be
taken warm, will keep the Stomach ex-
tended, and lie heavy for want of Juices
to ferment it, and raise the Steam. If it
be taken cold, it will condense the Steam,

and after fome Time, yield a few Juices to raise the Ferment. When the Stomach and Guts are kept diftended, and the Juices intended for Fermentation, &c. are hindered from fecreting out of the Blood into them for any confiderable Time, the Meat will not be duly digefted nor difcharged; and if near the fame Quantity of Juices, as are produced out of the Diet every Day, be not discharged with the Excrements, they must be discharged by Urine, Sweat, &c. or perhaps fall upon the Lungs, or remain in the Blood, and by Degrees overstock it, make it fharp, occafion Scurvy, Jaundice, Strangury, Rheumatifms, Gout, &c. And when by any means they get fudden Vent into the Stomach or Guts, occafion Fevers, Surfeits, Gout in the Stomach, Colics, &c. according to the Quality, Quantity, &c. When one has eaten a great Quantity of cold Fruit, or any fuch Thing, that the Juices in the Stomach cannot raife a Steam whilft they are fecreting, and fo are ftill prevented from making any Refiftance in the Stomach, the Glands will ftill fecrete as faft as the Ducts can convey the Juices into them, and at laft fecrete the Blood into the Stomach. And if fuch Fruit or other cold

Matter cannot be fermented, the Juices will fometimes open the Valves of the Oefophagus, and the Stomach will, by the Affiftance of the Preffure of the Air, Expanfion of the Steam in the Guts, and Contraction of the Mufcles of the Belly, throw it up. If it be carried down into the Guts, and abate the Steam there, it will both abate the Course of the Blood, and give way for the Juices to fecrete out of their Glands, and afterwards the Blood. If it raise a Ferment there it may occafion a Fever. If it open the Valves, and force its Way downward, it will occafion what they call a Bloody Flux. Indeed Cattle eat cold Herbs, &c. but in common Pasture they are fo long in filling their Stomachs, that they do not condense the Steam in a fhort Time, and their Blood contains not fo much Spirits or volatile Salts; fo that when the Steam is condenfed, the Juices do not flow in fo violently, nor are fo fharp. And they choose fuch Plants as they can digeft, and refuse the four cold Plants, and if for Hunger, or by being kept long to dry Meat, they be forced to eat too much of them at once, or too haftily, they have much the fame Effect as Colic, Gripes, &c. and fearce any Creature except Swine, H 2 will

will eat much cold raw Fruit; and 'tis likely it will have the fame Effects upon them. And as Cattle are ordinarily far longer in filling their Stomachs, fo they eat a much greater Quantity, and make greater and more frequent Difcharges in Proportion, and their Glands for Juices for Digestion must be contrived to make more leifurely, and more conftant Difcharges; and the Glands for difcharging the Excrements to be fooner filled, and more frequently difcharged. The Pilorus or Outlet from the Stomach into the Guts feems to have Valves, and the Sides of the Neck are thicker than other Parts, and the more Veffels there are, when they are filled, will clofe that Part fooner than where they are thin: whether when the Steam in the Stomach is spent, the Veffels in the Sides fill and contract the Pilorus, or fhut the Valves before we eat or drink, I cannot tell; but when Meatand Drink goes cold into the Stomach, the cold almost wholly condenses the Steam, and the Refiftance within being taken away, the Blood and Juices will be violently preffed thither by the outward Compreffure of the Air, and the Pilorus muft fhut and refift any thing from paffing out of the Stomach into the Guts,
