SECT. I. CHAP. XI. Of an Imposthume of the Lungs.
AVomica of the Lungs is something a-kin to an Empyema or Peripneumonie, considering that the morbific matter is always meer Pus, which notwithstand∣ing is generated in the Lungs without a Feaver and Phlegmon, yea without * 1.1 any great Cough or Spittle, as it were silently, and without noise; and frequently this evil doth not discover it self before it kills the Patient. Galen makes mention of this in lib. 1. de locis affectis; but among Authors who have written Systemes and the practi∣cal parts of Physick, mention thereof is seldom or scarce to be met with. Tulpius in lib. 2. chap. 10. describes this distemper after this sort. This evil (meaning an Im∣posthume of the Lungs) lurks in the beginning so secretly that it scarce discovers any signs of it self, besides, in the first place, a little dry Cough, and presently moist; which continuing for some time, the breath is drawn with difficulty, the spirit fails, and the body withers by degrees, although in the mean time the Spittle makes no shew, either of pus or blood; and if the Imposthume break by way of surprisal, the man is kill'd immediately. It is wont some∣times so to happen, but I have known many who in an Imposthume rising insensibly, being maturated, and at length breaking, have spit up great plenty of fetid corruption; and though with voiding daily such a Spittle, for many weeks, nay months, they be∣came very weak, and as it were, consumptive, yet at length by the help of Medicines after the Ulcer hath been mundified, and dryed, they have recovered their health entirely.
This disease, if we search into the formal reason and conjunct cause thereof, is in truth a concourse of ill humours gathered in some part of the Lungs; whose matter although * 1.2 it be heterogene and an enemy to nature, notwithstanding from the beginning ap∣pears not sharp, or irritative. For when at first being separated from the blood, it is deposited in some hollow place of the Lungs, perhaps in some bladdery cell, it doth neither raise a Cough nor produce a Feaver; but afterwards when sensibly encreased it compresses the neighbouring Vessels bringing blood, and moreover infinuates into the very blood passing by, incongruous Effluviums; from thence a small Feaver suc∣ceeds, with a certain disquietude, and feebleness; and at length being accumulated to its fulness, and maturated by a long digestion into mere Pus; breaking its nest ve∣ry much distended before, it flows out every where all about. But if the ways are not open for the issuing of the Pus, it incontinently mingles it self with the blood, and either impoysons it, or impedes it from Circulation; or rushing by heaps into the Tracheal passages; it doth fill most of them at once, and so stuffs them, that a suffici∣ent entrance is denied to air to kindle the blood, and presently the vital flame expires:
