a care that the tent put into those kindes of wounds may be fastened to the Pledgets, and also have somewhat a large head, lest they should be drawne as we sayd into the capacity of the Chest, for if they fall in, they will cause putrifaction and death.
Let Emplast. Diacalcitheos or some such like bee applyed to the wound. But if, on the contrary, you know by proper, and certaine signes, that there is much blood fallen into the spaces of the Chest, then let the orifice of the wound bee kept open with larger tents, untill all the Sanies or bloody matter, wherein the blood hath de∣generated, shall bee exhausted. But if it happen at any time, as assuredly it sometimes doth, that notwithstanding the Art and care of the Physition, the wound degene∣rates into a Fistula, then the former evill is become much worse. For Fistula's of the Chest, are scarse cured at any time, and that for divers causes. The first is, for that the muscles of the Chest are in perpetuall motion; Another is, because they on the contrary inside are covered onely with the membrane investing the ribbes, which is without blood. The third is, for that the wound hath no stay, by meanes whereof it may be compressed, sowed, and bound, whereby the lips being joyned together, the wound may at length be replenished with flesh, and cicatrized.
But the reason why wounds of the Chest doe every day heape up and poure forth so great a quantity of matter, seemes to be their vicinity to the heart, which being the fountaine of blood, there is a perpetuall effluxe ther eof from thence to the part affected. For this is natures care in preserving the affected parts, that continually and aboundantly without measure or meane it sends all its supplyes, that is, blood and spirits, to the ayde. Ad hereto, that the affected parts by paine, heate and conti∣nuall motion of the Lungs and midriffe, draw and allure much blood to themselves. Such like blood defiled by the malignity and filth of the wound, is speedily corrupted; whence it is that from the perpetuall affluxe of blood, there is a continuall effluxe of matter or filth, which at the last brings a man to a consumption; because the ulce∣rated partlike a ravenous wolfe consumes more blood by the paine, heate and moti∣on than can be ministred thereto by the heart. Yet if there bee any hope to cure and heale the Fistula, it shall bee performed, (after the use of diet, phlebotomie, and according to the prescript of the Physition) by a vulnerary potion, which you shall finde described when we treate of the Caries or rottennesse of the bones. Wherefore you shall make frequent injections therewith into the Fistula, adding and mixing with it syruput de rosts ficcis and mel rosarum. Neither doc I, if the putrefaction bee great, feare to mixe therewith Aegyptiacum. But you must have a care to remem∣ber and observe the quantity of the injected liquor, that you may know whether it all come forth againe after it hath performed its detergent office. For if any there∣of remaine behinde in the corners and crooked passages, it hurts the part, as corrup∣ted with the contagion thereof.
After the injected liquor is come forth, a pipe of gold, silver or lead, shall bee put into the fistulous ulcer; and it must have many holes in it, that so the filth may passe forth at them; it must be fast tyed with strings, that it may not fall into the capacity of the Chest.
A great spunge steeped in aqua vita and wrung forth againe, shall bee layd hot to the end or orifice thereof, both to hinder the entrance of theayre into the Fistulous ulcer, as also to draw forth the filth thereof by its gentle heate, the which thing the
