All Expences should be paid by the Publick, and no Charges ought to be
thought great, which are counterbalanced with the saving a Nation from
the greatest of Calamities. Nor does it seem to me at all unreasonable,
that a _Reward_ should be given to the Person, that makes the first
Discovery of _Infection_ in any Place: since it is undeniable, that the
making known the _Evil_ to those, who are provided with proper Methods
against it, is the first and main Step towards the overcoming it.

ALTHOUGH the Methods taken in other Countries, as well as in our own,
have generally been different from what we have here recommended; yet
there are not wanting some Instances of extraordinary Success attending
these Measures, whenever they have happened to be put in Practice.

THE Magistrates of the City of _Ferrara_ in _Italy_ in the Year 1630,
when all the Country round about them was infected with the _Plague_,
observing the ill Success of the Conduct of their Neighbours, who, for
Fear of losing their Commerce, did all they could to conceal the
Disease, by keeping the Sick in their Houses, resolved, whenever
occasion should require, to take a different Method. Accordingly, as
soon as they received Information, that one had died in their City of
the _Pestilence_, they immediately removed the whole Family he belonged
to into a _Lazaretto_, where all, being seven in Number, likewise died.
But though the Disease was thus malignant, it went no farther, being
suppressed at once by this Method. Within the Space of a Year the same
Case returned seven or eight Times, and this Management as often put a
Stop to it. The Example of this _City_ was afterwards followed more than
once by some other Towns in the same Territory with so good Success,
that it was thought expedient, for the common Good, to publish in the
_Memoirs_ of the People of _Ferrara_ this Declaration: _That the only
Remedy against the Plague is to make the most early Discovery of it,
that is possible, and thus to extinguish it in the very Beginning_[80].

NO less remarkable than this Occurrence at _Ferrara_, is what happened
at _Rome_ in the _Plague_, I have taken Notice of before, in the Year
1657. When the Disease had spread itself among both Rich and Poor, and
raged in the most violent Manner; the _Pope_ appointed Cardinal
_Gastaldi_, to be Commissary General of Health, giving him for a Time
the Power of the whole _Sacred College_, with full Commission to do
