This V. The mentioned Cafe is more manifeft by thefeTa- 
Tank'd *irly, and it is two to one but that a Phyfician over Pur- 
ges or under Purges any Perfon in Health ^ and if more 
Cafes in Sicknefs arc fuppos’d, the odds will encreafepro- 
portionably. Experience confirms this exactly ; For if 
the middle Dole is given to one of the lowed Conditu- 
rion, and the middle Dofe is to purge 7 or 8 times 5 in 
that cafe, the Perfon of the lowed Conditution is purg’d 
near twice as much as he ought to be 3 and if given to 
one oi the highed Conditution, he is purg’d but half of 
what he lliouid be. But if the Dofe of tiie highed Con- 
ditution is given to one of the middle Conditution, he 
is purg’d twice as much as he ought to be 5 and if given 
to one of the lowed, he is purg’d four times as much, or 
about thirty times, as we find true by daily Experience. 
But if the Quantity of Blood, the Age, or Sicknefs con- 
tribute to the Errour, it may prove fatal. If this Confi- 
deration were illudrated by a proper number of Exam- 
ples, we (hould find fomc hundreds of, othervvays una-
