Sec. 65. When the Sick has not been sufficiently bled, or not soon enough; and even sometimes, which I have seen, when he has been greatly weakened by excessive Bleeding; so that the Discharges by Stool, Urine, Expectoration and Perspiration, have not been sufficiently made; when these Discharges have been confused by some other Cause; or the Disease has been injudiciously treated; then the Vessels that have been inflamed, do not unload themselves of the Humours, which stuff up and oppress them: but there happens in the Substance of the affected Lung, the same Circumstance we see daily occur on the Surface of the Body. If an inflammatory Tumour or Swelling does not disperse itself, and disappears insensibly, it forms an Imposthume or Abscess. Thus exactly also in the inflamed Lung, if the Inflammation is not dissipated, it forms an Abscess, which, in that part, is called a _Vomica:_ and the Matter of that Abscess, like the external ones, remains often long inclosed in its Sac or Bag, without bursting open its Membrane or Case, and discharging the Matter it contains. Sec. 66. If the Inflammation was not very deeply seated in the inward Substance of the diseased Lung; but was extended to its Surface, that is, very near the Ribs, the Sac will burst on the Surface of the Lung; and the Matter contained in it must be discharged into the Cavity, or Hollowness of the Breast, between the Lung, the Ribs, and the Diaphragm or Midriff, which is the Membrane that divides the Breast and the Belly. But when the Inflammation is considerably deeper, the Imposthume bursts withinside of the Lung itself. If its Orifice, or Opening is so small, that but little can get out at once; if the Quantity of all the Matter be inconsiderable, and the Patient is at the same Time pretty strong, he coughs up the Matter, and is very sensibly relieved. But if this _Vomica_ be large, or if its Orifice is wide, and it throws out a great Quantity of Matter at once; or if the Patient is very weak, he dies the Moment it bursts, and that sometimes when it is least expected. I have seen one Patient so circumstanced expire, as he was conveying a Spoonful of Soup to his Mouth; and another, while he was wiping his Nose. There was no present Symptom in either of these Cases, whence a Physician might suppose them likelier to die at that Instant, than for some Hours before. The _Pus_, or Matter, is commonly discharged through the Mouth after Death, and the Bodies very soon become putrified.
