BUT in this place I must farther observe, that the abovesaid _spirituous Substance_, in which the effective Virtue of CONCEPTION resides, is endued with _four_ distinct _Faculties_, which perfect as _many_ different _Operations_, all subordinately effected in the _Constitution_ of the CONCEPTION, _viz_. I. THE _animatïve_ or _vivificating_ Faculty of the MENSTRUUM, called by some the first _Constitutive Faculty_ of _Conception_, operating, as above, in _Seven Days_; which is otherwise term’d the Time of _Spumification_, _Lactation_, or _Coagulation_. II. THE _separative_ or _severing Faculty_ of the Parts of the grosser _Materials_ of the _Conception_, destinated for the respective _Constitution_ of the different _Organical Members_; which, being the Work of the next _Eight_ or _Ten Days_, is perfected about the 15th or 17th _Day_ from CONCEPTION; and this is called the Time of _Lineation_ or _Ramification_, when the GENITURA receives the Name of EMBRYO. III. THE _collocative_ or _ordinating Faculty_ of all the severed material Parts of the different _Members_, disposing and placing them according to the _Law of Nature_, in due Order, Figure, and Situation; which, happening the following[15] _Twelve_ or _Fifteen Days_, about the 27th or 32d Day from _Conception_, is called the Time of _Carnification_; when the Embryo receives the Name of FOETUS. NOW according to the Maxims of _Astrology_, as all _inferiour Bodies_ are govern’d and influenced by _Superiours_, so the _Seven Planets_ have Dominion over the _Man_, not only from the Day of _Birth_, but also from the Moment of _Conception_; yet not _All_ at one and the same Time, but every _one_ in their _Order_, reigning each its _peculiar Month_. According to which Principles, SATURN reigns the _first_ Month, suppeditating the humid and liquid _Substance_ of the GENITURA and EMBRYO, through his frigid and siccid _Quality’s_ due _Coagulation_ for generating the _Man_; by virtue of whose _Siccity_ the _uterine Retentions_ also happen. IV. THE _formative_ and _figurating Faculty_ of all the _Members_ of the Body, imparting their respective _Shape_, _Figure_, and natural _Form_, to every particular _one_; which being the Work of the next _Eight_ to _Eighteen Days_, is perfected about the 35th, to the 50th Day from CONCEPTION, and is called the Time of _coarticulate Formation_, when the FOETUS, or CYEMA, is stil’d _Infant_. AND in this, the _second Month_, JUPITER is supposed to exert his Power in the _Seed_, by his calid and humid _Qualities_; and thereby to vivify the _Spirits_, strengthen the _Members_, and give Augmentation and Growth to the whole FOETUS: So that the _interior Members_ are not[16] only conspicuous, but also _Legs_ and _Arms_ appear perfectly delineated, and are (at this time) distinctly _visible_; when also the _Head_ takes its Distance from the _Shoulders_, the _Arms_ from the _Sides_, and the _Legs_ are plainly parted.
