lefs, according to the conditution and difpofition of the 
air in the fame climate: for, feme years, fevers are 
epidemic, and very mortal : other years, they are 
epidemic, but not mortal ; the imall pox the fame ; 
See. And fo the plague is fome years more violent, 
and has fome fymptoms different from what it has in 
other years; which, I take for granted, mnft be the 
reafon of any difference, that may appear in the remarks 
of the celebrated authors already mentioned. There is 
one extraordinary fymptom, which the mod of thefe 
authors mention, tho’ none of them prove it, or pre- 
tend to have leen it; which feems to me inconfident and 
incompatible with the animal ceconomy ; making ftill 
proper allowance for Omnipotence and Divine Ven- 
geance, as in that of Sennacherib’s numerous army, 
and many other fuch plagues, mentioned in Scripture. 
What I mean, is, that a perfon cannot die of the 
plague (fuch as it appears among us) indantaneoufly, 
or in a few hours, or even the fame day, that he re-

long experience in this country, that all fuch, as have 
the plague, conceal it as long as they can, and walk 
about as long as poffible. And I prefume it muff be 
the fame in all countries, for the fame reafon, which 
is the fear of being abandoned and left alone; and fo, 
when they druggie for many days againd it, and at 
lad tumble down in the dreet, and die fuddenly, peo- 
ple imagine, that they were then only infedted, and 
that they died indantly of the infedtion ; tho’ it may 
be fuppofed, according to the rules of the animal 
ceconomy, that the noxious effluvia mud have been 
for fome time mixed with the blood, before they 
£Ould produce a fever, and afterwards that corruption
