BUT the next Spring indeed appeared some Remains of the Contagion, which was easily conquered by the Physicians, and like the Termination of a common _Intermittent_, ended in a healthful Recovery: Whereupon the whole Malignity ceasing, the City returned to a perfect Health; not unlike what happened also after the last Conflagration, when a new City suddenly arose out of the Ashes of the old, much better able to stand the like Flames another Time. [Illustration] SECTION II. _Of the Cause of a Pestilence, and a Contagion._ AS it is our Purpose here to enquire into the Origin of the late Plague, and find out both its manifest and hidden Causes; I cannot judge it necessary to go into the usual Length of Writers, in a particular Recital of all those remote Regards which they distinguish by Supernatural, Preternatural, and Natural; because by such Means this Treatise would be drawn out into an almost infinite needless Distinction. THAT the Truth therefore may at once be brought into an open Light, and the Pestilence appear in its genuine Affections, I think it proper to premise this one Thing, because the whole depends upon it, _viz._ That the Pestilence is the most notorious of all popular Diseases, and depends upon some Cause equally common, and in every respect adequate to its extensive Effects; which being granted, it naturally follows, that all particular Causes which may accidentally intervene, (the Recital of which would be very tedious) are resolvable into this one. AND for what concerns that Pestilence now under Enquiry, this we have as to its Origin, from the most irrefragable Authority, that it first came into this Island by Contagion, and was imported to us from _Holland_, in Packs of Merchandice; and if any one pleases to trace it further, he may be satisfied by common Fame, it came thither from _Turkey_ in Bails of Cotton or Silk, which is a strange Preserver of the pestilential Steams. For that Part of the World is seldom free from such Infections, altho’ it is sometimes more severe than others, according to the Disposition of Seasons and Temperature of Air in those Regions: But if any would yet more intimately be acquainted with its Origin, it concerns him to know all the Changes the Air in these Climates is subject to, and its various Properties of Dryness, Moisture, Heat, Cold, _&c._
