only mention four Sorts of them. The Fir/l fhewsitfelf 
fomewhat eminent and rjfing, of a dark brown, the 
uppermoft Skin appearing fomewhat dry, as if it was 
burnt, and has withal a Lead-coloured Circle. In the 
beginning it is frequently no bigger than a Pea, but if 
not prevented increafesin afhort time to the bignefs of 
a Crown-piece. Inwardly it is moifter than the follow- 
ing Species , and may be eafier feprrated. It’s Seat is ge- 
nerally in the fkfhy Parts, and is to be found on the 
Shoulders, Sides, Hips, Neck, and alfo on the Arms and 
Legs. 
But the fecofid Sort lies fomewhat deeper, and feems a 
little more deprefled. The Efcar is in the middle of it, 
which is wholly Dark and Alh-coloured, full of fmall 
Cuts, as it were burft by too great a Drynefs, and has a 
ftrong Lead-coloured Circle, behind which the found 
Flefh looks red and Ihining. It very much eats the Flefn 
about it, and fixesits Roots very deep. In itsSeperation 
it feels dryer than the former, and may be taken out by 
pieces* It is fixed generally where the Flefti is thickeft, 
as on the Buttocks, the Calf of the Legs, and under the 
|horr Ribs towards the Back. Thefe two Species burn 
violently ftrong beyond the reft,infomuch that a red-hot 
Iron can hardly occafion more Pain 5 and indeed the 
Patients (not to mention other Symptoms that accom- 
pany them ) a^e aimoft killed by the meer Pain of 
them. 
The third SoYt is not very big, nor of a very large 
Circumference. At firft it appears like a Blood fwelling, 
notfo black as the former, the Skin being alfo fome- 
what wrinkled. In its Increafe fmall Blifters arife on the 
middle of it, and form an Efcar in fmall Clutters, which, 
as an Ingenious Phyfician obferved, were fmall Carbun- 
cles* They are commonly firuated in Membranous and 
Tendinous Parts, as towards the Knees, behind the Ears, 
upon the Toes ,_&c.
