Francis Gentil had, befides thefe fymptoms, almoft 
the whole mefentery mortified, and an anthrax or 
carbuncle at the upper and fore-part of the arm-pit, 
and the whole body of a livid colour. This car- 
buncle proves, that thefe malignant fevers were fome- 
thing pefiilential. 
I fay nothing of the fmall-pox, which hardly ever 
leaves this climate in any feafon of the year, but 
which neverthelefs is more common towards the end 
of lummer, and in autumn, and for the moff part 
is accompanied with the miliary eruptions, which

malignant fevers, that put on the appearance of pe- 
ripneumonies, became mortal in feven days, and we
