CHA P. XIV. SECT. I. The common and accidental Agents or Causes, which contribute to make the Juices secrete out of the Blood-Vessels into the Glands on the sides of the Stomach and Guts, with their Effeets and outward Appearances.

D Ifcharging the Meat and Drink, and

U especially the Steam, abating the Fermentation, condensing the Steam by cold Meat or Drink, or by cool heavy Corpuscles in them, &c. which abates or takes away the Resistance within, and suffers the Pressure of the Air, and the Steam in the Blood vessels to fill the Blood vessels in the sides of that part of the Stomach or Guts, contract them, and force the Juices out of the Blood-vessels into the Glands in their Insides, and stock them there for Fermentation, Discharge, &c. There may be other Causes that contribute, such as the Thinness of the Blood, Cleanness and Openness of the Ducts into the Glands, cool Air to prevent the Steam from issuing too fast at the Pores, moderate Action, &c. If the Juices

be

be secreted in due Proportion, the Blood
will be sweet and cool; if too few, the
Blood will be too hot and sharp ; if too
many, the Excrements will be too hot
and sharp, &c. as aforesaid.

$. E Ć T. II.
Which binder's the Juices from je-

creting into the Glands, &c. TEAM, which keeps the sides of

the Stomach and Guts too much extended, flattens the Blood-vefsels, hinders the Blood from circulating thro' them in due Quantity, and preftes the Glands, that the Air cannot drive the Juices into them ; either by rising in too great Quantity, or by being too gross, or by the Straighthefs ot Fousnefs of the lacteal Veflels; Thickness of the Blood, or frequently for want of Action."

.. SECT. III.

Which opens the. Mouths or Values of the Glands, in the several Parts, to difcharge the Juices for the faveral Ufes, &c.

Ncrease of the Pressure of the Atmos

sphere, or Diminution of the Expanfion of the Steam within, or the Corpufcles of Fire, Salt, or pointed Bodies apo plied in proper Fluids or Steam, with the Motion of the Fluids or Steam, or other proper Agents to impell or wrest them, to fret of the Coats or Phlegm, &c. which cover their Mouths with a sort of Skin, or to cleanse the stagnant Matter out of their Mouths, or to open their. Mouths, by being pushed in like Wedges, or in extraordinary, Cafes, by taking off or thinning this outward Skin, cutting their Valves, or Sides, &c. It may seem strange to affert, that the small Corpuscles of Fire, or volatile Salts, can open the Valves of the Glands in the Stomach, &c. But if we consider that the Valves of those Glands, which we see or discover with Glasses, are composed of Glands still smaller and fmalter, and

Valves

[merged small][merged small][ocr errors]

Valves to them proportionable to the Magnitudes of the Corpuscles of Fire, Salts, &c. even supposing as smaller as we can imagine, and the Corpuscles which constitute the Juices in them still smaller, and that opening the Mouths of the smallest Glands discharges the Juices out of them, and weakens and opens the Valves of the Glands successively larger; and that if the Corpuscles do but open the Mouths of the smallest Glands, till the Steam which before circulated into the Blood, get Vent at the Mouths of them, it will soon open the Valves wider, and that if small Bodies by rebounding, can expand and stretch the Vessels that contain them to any Extent, which any other Force can, the Operation will appear more practicable. The Consequences of their being opened too much, or continuing open too, long, have been mentioned above.

SECT. IV. - Which Shut the Mouths of the .. :: : Glands, &c. [xpansion of the Steam within, DiL minution of the Pressure of the Air without; the Thickness or Closeness of

the

the Glands within, and the Weakness or Openness of the outward Pores, Phlegm, or tough close Matter, which cover the Mouths, or stagnant Matter in the Mouths of the Glands, Corpuscles of some forts; of Matter, which they call Astringents or Stipticks, which dry or thicken the Juices in the small Valves, and scorch the Valves, and some bluat or flat ones, which are so figured, as to fit and stop their Mouths,. or to be pressed against, and cover them, or, &c. That Corpuscles infinitely small can stop the Mouths of the Glands, will not appear so strange if it be likewise considered, that stopping the Mouths of the smallest Glands, which compose the Valves of the greater Glands, stops the Mouths of the greater, by hindering the Juices from being discharged out of the Glands, which compose the Valves of the greater Glands, and hindering them from opening. If when the Glands are full, the Steam can rise and extend the Stomach without emptying the Glands, it must cause a Sense of Fulness or Stitches and Pain, acccording to the Strength and Quality of the Steam.
