IN the _Fifth_, I have ingenuously laid open the whole Mystery of _Midwifery_, as to all Sorts of BIRTHS, whether _Natural_ or _Preternatural_, and faithfully laid down the Fundamental Principles and most certain Rules of this _Profession_; and that not only according to the best _Notions_ of my own Application and Study, or the real _Dictates_ of my proper Practice and Experience; but also according to the most ingenious Precepts and infallible _Maxims_ of the ablest and most polite _Professors_ of this excellent _Art_, and that also according to its newest and latest _Improvements_: And in these _Cases_, I have neither fear’d the Invectives of the Æmulous _Zoilus_, nor regarded the Snarlings of the reprehensive _Momus_: For Wise Men are not any longer to be entertained with _Ænigmas_, since GOD hath said, _Fiat Lux_. IN the _Sixth Part_, I have not only prescrib’d the due _Regimen_, and provided for the Safety and happy _Recovery_ of the _Child-Bed-Woman_, but also taken a suitable and corresponding Care of her _Babe_; As I have farther instilled particularly upon the various Disasters incident to both _Mother_ and _Child_, in their respective tender Conditions of _Child-Bed_ and _Infancy_. IN the _Seventh_, I have dilucidated the _Philosophical History_ of all the different Sorts of _Preternatural Conceptions_ as well as BIRTHS; and insisted at large upon the Theme of Women’s _Sterility_ or _Barrenness_. IN the _Eighth_ and last _Section_, I have not only defin’d the _Widow-State_, as far as it concern’d my Purpose, but also diligently pursued the _Subject-Matter_, and traced down the Particulars of their common _Grievances_. THESE, I say, are the general Heads of the WORK, which are all again sub-divided into their proper respective Particulars; and consequently every general _Head_ or _Section_ assign’d its own relative _Chapters_, for the singular Benefit and more easy Comprehension of the _Reader_. And these _Chapters_ consisting of 130 in Number, I have, with respect to every singular _Distemper_ mentioned in them, FIRST, defin’d the Nature of the _Disease_; SECONDLY, accounted for its _Causes_; THIRDLY, I have given the _Diagnostick Signs_ or _Symptoms_; FOURTHLY, the _Prognosticks_ or Degrees of Danger; to which I have FIFTHLY and lastly added the Method of _Prevention_ in many Cases, and That of CURE in All: So that there is almost not one _Disease_ which can affect the Woman from her _Birth_ to her _Death_, in _Child_, _Maiden_, _Wife_, or _Widow-hood_, whose _Essence_, _Species_, _Differences_, _Causes_, _Signs_, and _Prognosticks_, we have not sufficiently clear’d up.
