Stomach, and the Steam will go off hot, and caufe a burning Heat in the Parts, and the Steam fo loaded with Salts, will open the Mouths of the Glands in every Part where it paffes, make them fecrete continually too much, and fo by Degrees emacerate the Body. If they bear too great a Proportion of Oil, they have the contrary, Effects. The Excrements can be fermented or mixed with Juices, till they be exceeding fharp and hot in the Guts, and that they fcorch or fret the End-Gut and Fundament as they are difcharging, and 'tis likely they can open the Glands in all the Valves, and with the Affiftance of the Steam, force their Way till they are difcharged; but whether the Excrements can be fermented to fuch a Degree, that the Corpufcles freed out of them, without a Mixture of the Juices fecreted out of the Blood, can open the Glands in the Valves, and affift in difcharging themselves out of the Stomach, or any Part of the Guts, I cannot tell. When one has a free continued Loofenefs, the Excrements are whitish, and either fome white Juices return out of the Blood, or the white Juices we call the Chyle, are not difcharged out of the Excrements, or the Excrements are of that

Colour,

Colour, when they are fermented to fuch a Degree, and are difcharged at that Des gree, like Ale, which is white when working, and after brown. When fuch a Looseness has continued for fome Time, fo that the Tenfion of the Guts is weakned, the outward Parts will be contracted, the outward Veins vifibly straightened and made smaller, and the Kidneys being less compreffed by the Steam within the Guts, and the Veffels and Glands in them being fuffered to extend, they will fecrete the Urine thick and muddy, and 'tis likely the Liver and Pancreas being lefs compreffed, will fecrete a greater Quantity of Juices, or Juices of a groffer Confiftency, and 'tis found by Experience, that the Corpufcles in feveral forts of Meat and Drink, in Simples, Minerals, &c. ftop the Glands which iffue the Juices to open the Valves, or entangle or abforb the Juices or Agents which are called by diAbfor- verfe Names, viz.

bents, En- And the Corpufcles in others open their craffants, Mouths, or excite fome latent Juices in Agglutinants, Bra- the Stomach or Guts which open them, cers, &c. and make them discharge their Juices and

discharge their Excrements, which are alfo called by various Names, according to the Quantity of Corpufcles in each, or the

Quantity

any

Quantity given at once, as Openers, Purges. And when the Glands have been stopped for confiderable Time, upon their being opened, the Juices will flow up in greater Quantity, and have more forcible Effects. And when they have been forcibly opened by Phyfick, or any other Accident to fecrete their Stock of Juices, and what would afterwards pafs out of the Blood, they fecrete not naturally for feveral Days. And the fame Agents have the fame Effects upon the different Parts of the Body, outward or inward, in Proportion to the Degree of Force which moves them, the Thickness or Thinnefs of the Skin or other Defence, the Strength or Weakness of the Glands, the Widenefs or Straightnefs of the Valves, Pores, &c. And different Agents or different Quantities, or moved with different Force, open the Valves or Pores, and let the Juices be preffed out in any Part; fome, thofe in the Mouth to discharge the Saliva; fome, thofe in the Stomach to discharge the Bile; fome, to blifter or take off the outward Skin, &c.

Which open the Paffages and Valves where the Urine fecretes.

OLD Meat, or weak fpiritlefs cold Liquor, which abates the Steam in, the Guts, takes off the Preffure upon the Kidneys, lets their Ducts open: cold Air which huts the Pores, and prevents the Fluids from perfpiring, Salts or harp Corpufcles which cleanse the Glands in the Kidneys, and fo render them wider, or which open the fmall Glands in the Sides of those Paffages, and make them fecrete the Juices in them, and thereby render the Paffages liable to be extended or widened by the Fluids and Steam, and enable them to discharge the Phlegm, Salts, Gravel or Stone, which ftopped or fwelled, or ftraightned the Parts, and afterwards thicker Urine. There are acid Corpufcles in fome Fluids like thofe in Rennet, which by their Smallness or Figure feem to be adapted to divide or thin Fluids, and let the groffer Corpufcles fubfide and precipitate, and thereby render. the Fluid thinner, and more liable to be fecreted by Urine. When the Water is

fecreted

fecreted into the Bladder, and we open the Valve in its Neck, which feems to be done partly voluntarily, the Steam in the Guts preffes it out, pushes down the End-gut (and if it be open) breaks backward; and when it gets Vent in Quantity, the Water iffues weakly. When the Steam preffes the Excrements, and gives us an Inclination to a Stool, the Preffure of the Steam, which rises to difcharge the Excrements, preffes the Bladder, and gives us an Inclination to difcharge the Urine; we discharge the Water firft, and that gives the End-gut Liberty to extend farther, and make Paffage for the Excrements. When these

Paffages are too wide, or open, they drain too much of the Fluid thin Parts out of the Blood, and carry off the Juices, which fhould be referved for other Ufes, and quickly disorder all the Operations in the Body.
