Transcriber's Note: The original publication has been replicated
faithfully except as shown in the TRANSCRIBER'S AMENDMENTS near the end of
the text. To preserve the alignment of tables and headers, this etext
presumes a mono-spaced font on the user's device, such as Courier New.
Words in italics are indicated like _this_. But the publisher also wanted
to emphasize words in sentences already italicized, so he printed them in
the regular font which is indicated here with: _The pirates then went to
+Hispaniola+._ The FOOTNOTES: section is located near the end of the text.

                                  THE
                                PREFACE.


_IT may be needless to acquaint the +Reader+ why the following +Sheets+
are published at this Time, we being all but too justly apprised of the
Danger there may be, of wanting those Helps, which are here intended to be
supplied, as far as such Means as these can do it._

_THE +Treatise+ of Dr. +Hodges+ contains the best Account of the late
Visitation by a +Plague+ here in +England+, of any hitherto extant; and
though some Readers may indeed observe, that the Enthusiastick Strain of
the preceeding Times very much hurts his Style and Perspicuity; such an
Influence had the Spirit of Delusion even over Matters of Science:
However, the most affected Peculiarities and Luxuriancies of that kind are
here avoided._

_WHAT is hereunto added, hath been partly extracted from Papers wrote some
Years ago, and partly put together since our present Apprehensions from
Abroad. The Enumeration of so many Causes of a Pestilence, or like
Changes, as have no Relation to the present Case, may to some perhaps seem
superfluous; but my Design hereby, was only the better to inculcate a
right Understanding of a +Contagion+, which is the last Consequence, and
highest Degree of Aggravation they are capable of rising to; and gradually
to lead Persons, not well accustomed to such Matters, from the more
obvious, to the more secret Means of bringing such terrible Changes into
our Constitutions._

_WHAT relates to such precautionary Means for our Security against the
present Infection now Abroad, as concern the Magistrate, I have presumed
to say but very little to; because I understand such Instructions are now
waited for from a very great and able Physician: But, with Submission to
the wisest, I cannot but repeat it here again, that no humane Means seems
more absolutely necessary, than to remove the Infected immediately upon
their Seizure, out of all great Towns, and provide for their due Support
in all Things, in open
