ious Humour is thrown out either by _Tumors_
in the Glands, as by a _Parotis_, _Bubo_, and the like; or by
_Carbuncles_ thrust out upon any part of the Body. And these Eruptions
are so specific Marks of this Distemper, that one or other of them is
never absent: unless through the extreme Malignity of the Disease, or
Weakness of Nature, the Patient sinks, before there is time for any
Discharge to be made this way; that Matter, which should otherwise have
been cast out by external _Tumors_, seizing the _Viscera_, and producing
_Mortifications_ in them.

SOMETIMES indeed it happens, by this means, that these _Tumors_ in the
_Glands_, and _Carbuncles_, do not appear; just as a bad kind of the
_Small-Pox_ in tender Constitutions sometimes proves fatal before the
_Eruption_, by a _Diarrhoea_, _Haemorrhage_, or some such Effect of a
prevailing Malignity.

THE _French_ Physicians having distinguished the Sick at _Marseilles_
into five _Classes_, according to the Degrees of the Distemper,
observed _Bubo's_, and _Carbuncles_, in all of them, except in those of
the _first Class_, who were so terribly seized, that they died in a few
Hours, or at farthest in a Day or two, sinking under the Oppression,
Anxiety, and Faintness, into which they were thrown by the first Stroke
of the Disease; having Mortifications immediately produced in some of
the _Viscera_, as appeared upon the Dissection of their Bodies[17]. And
this Observation of the _French_ Physicians, which agrees with what
other Authors have remarked in former _Plagues_, fully proves, that
these Eruptions are so far from being caused solely by the greater
_Violence_ of this Disease, than of other Fevers, that they are only
absent, when the Distemper is extraordinary fierce; but otherwise they
constantly attend it, even when it has proved so mild, that the first
Notice, the Patient has had of his Infection, has been the Appearance of
such a _Tumor_: as, besides these _French_ Physicians, other Authors of
the best Credit have assured us. From whence we must conclude, that
these _Eruptions_ are no less a Specific Mark of this Disease, than
those are, by which the _Small Pox_ and _Measles_ are known and
distinguished. And as in the first _Class_ of those attacked with the
Plague, so likewise in these two Distempers we often find the Patient to
dye by the violence of the Fever, before any Eruption of the Pustules
can be made.

THIS Circumstance of the Plague being mortal before a
