signs be joyned there with; as also if the Abdomen be violently pressed, the Patient will perceive some inward pain: it is true, that by violent compression you may cause pain in sound places; but if you perceive more pain in one part than in another, after all parts have been pressed, and when that part is alwaies most pained, and the more by pressing, you may strongly conjecture that the impost∣hume is there.
If at length there come forth Matter, then the Imposthume will be manifest. Commonly it is voi∣ded by stool of divers sorts according to the disposition of the part affected, and of those adjacent.
Hence one while the Matter is pure and white in great plenty, without sence of pain, when it is sent by the Meseraick Veins into the Guts, somtimes when the Imposthume is in the thick and low∣est Guts, the Matter is mixed with the Excre••ents, somtimes it is sent to the Reins, and cast forth by Urine; somtimes being sent in great quantities between the Peritonaeum, and the Muscles of the Ab∣domen, it falls into the Cavity of the Belly by breaking of the Peritonaeum, or breaks outwardly by an Imposthume, so that a great quantity of Matter flows from the Navel, and somtimes Worms there∣with, through the corruption of the Mesentery. And that which sent forth by stool (which is the u∣sual) is somtimes white and laudable, as was said; somtimes mixed with blood or water, somtimes black blood, and stinking, somtimes other black Matter, or of divers colors. But whether this puru∣lent Matter come from the Mesentery, Liver, Spleen, or other part, it is known by the proper signs of every part affected.
When the Imposthume is broken, and the Matter floweth, it is certain that there is an Ulcer in the Mesentery, which somtimes is quickly cured, and somtimes it is of long continuance, and brings rot∣tenness upon the whol part, and a Gangrene.
As for the Prognostick: The Imposthume of the Mesentery is dangerous; for if it continue long in the part, as it often happens, it breeds filthy rottenness, or a Gangrene, or brings the Patient into a Consumption or Dropsie. If it break, and the Ulcer be not quickly cured, but gets an evil condition, it hath the like event, a Gangrene, Consumption, or Dropsie. Somtimes when the Imposthume is bro∣ken, and very stinking Matter is sent into the Cavity of the Belly, the Patient dies suddenly. The Scirrhus, or hard Tumor of the Mesentery is lest dangerous, and if it be new will admit of a Cure; but if it be old, it brings the Patient to a Dropsie.
The Cure of these Diseases, is to be varied according to the diversity of them. And first, an Im∣posthume bred requires opening and evacuation, and it must be softened with opening and purging Medicines, such as are laid down in the Obstructions of the Liver and Spleen, not omitting outward Softeners and Looseners, Fomentations, Cataplasms, and Liniments, which do make the Matter of the Imposthume thin, and open the passages that the Matter may better be voided.
After the Imposthume is opened, you must clense the Ulcer and heal it; for which purpose the Remedies mentioned in the Cure of the Ulcers of the Stomach, Liver, Reins, and Womb, are very good; of which a wise Physitian may take his choyce according to the divers dispositions both of the Bodies, and the Diseases.
And a Scirrhus of the Mesentery is cured with the same Medicines, which are set down for the Cure of the Scirrhus or hard Swelling of the Liver and Spleen.
Chap. 4. Of the Diseases of the Pancreas, or Sweet-bread.
THe Ancient Anatomists knew no action of the Pancreas, or Sweet-bread, but the use only▪ namely, to prop the Vessels, least they should be in danger of breaking, and to be instead of a Pillow to the Stomach, least when it is full it should be hurt by the hardness of the Vertebrae or Back-bone. But the Modern Anatomists have ascribed very great action unto it; namely, the first preparation of the Chyle, and clensing of it, so that it may be brought to the Liver more pure; which the milky Veins seem to confirm, because they are dispersed through the Pancreas. Besides, in the middle of it there is an open passage which goes to the Guts, by which it is probable that the Excre∣ments of the Chyle are purged; therefore the Pancreas hath its Diseases, which hurt the whol Body, especially Obstructions and Tumors, as the Mesentery hath; namely, when the Chylous Matter is crude and thick, and is brought to it from the Stomach, not sufficiently digested, and when it doth not freely flow from it.
Riolanus observed a Scirrhus of the Pancreas, in Augustine Thuanus, that wrote the History of his Times most elegantly in Latin; who when he had for four yeers, among other Symptomes, a hea∣viness continually in his Stomach, especially when he walked or stood still, without Swelling or hardness in the Hypochondria, had a Pancreas as big as his Liver, after he was dead, hard and Scir∣rhus, full of knots like Pidgeons Eggs.
But because the Pancreas is covered with the Stomach, its Tumors are scarce to be felt; and this is
