I. THEY are called in Greek, 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉. in Latin, Gangraena; and in English, a Gangrene. II. 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉. in Latin, Syderatio, and Sideratio, also Sphacelus; in English, a Sphacelus, or Mortification.
II. Sennertus saith, that Gan∣grene and Sphacelus are neither Tumors nor Ʋlcers; neither will he have Sphacelus to be so much as a Disease, since it is the very mortification, or destruction of the Part. Yet with the favour of that Learned Man, tho' in re∣spect to the Part only, he will have it no Disease; yet in re∣spect to the whole Body, it is a very great one.
III. A Gangrene is a great and terrible Distemper, tending to a Mortification, which may be in∣duced without any Tumor at all: but yet because it most frequently follows Tumors, and chiefly Inflammations, we thought good to treat of it among Tumors; whereas others, (because that when a Part is Gangrenated, an Ulcer necessa∣rily follows thereon, and that after a Sphacelus, an Ulcer is left remaining) treat of them among Ulcers.
IV. Gangraena, is an imperfect Mortification of the Part by little and little, thro' violence of much in∣flamed Matter and Blood, which so stop the passages, as that the natural heat cannot have recourse thereto. If it come of Inflammation, the red Colour, Pain, Sense and Beating decays; waxing pale, livid, black and soft, yielding to the Fingers, without rising again.
