THE particular _Description_ of _MONSTROUS CONCEPTIONS_ in the preceding _Chapter_, leads me, of Course, to treat of _another Sort_; which I shall comprehend under the _Title_ of _Deformed CONCEPTIONS_. _This Sort_ happening almost in _all Countries_ promiscuously, tho’ in _some_ more frequently than in _others_, becomes almost in _all Parts_ Daily obvious to our _Eyes_, so that we need be at no great Pains to prove the _Reality_ of _deformed_ BIRTHS, but rather inquire into the _Causes_ of such uncouth _CONCEPTIONS_. IN short therefore as to _these_, if we only look back and reflect on the three preceding _Chapters_, we will find the _Causes_ of the _present Case_ very evident and sufficiently manifest, if not particularly included in the _Latter_: Wherefore I have only farther here to observe, that all such _Præternatural CONCEPTIONS_, degenerate from the _Natural_, in proportion to the _Prevalency_ of their _Cause_ or _Causes_; So that the _Cause_ being less considerable in _this_, than in the _foregoing Case_, instead of a _MONSTROUS_, we have only a _deformed_ BIRTH: Such as a _Scurf-Head_, a _discolour’d Skin_, an _ugly Visage_, _disagreeable Features_, _distorted Mouth_, _crooked Nose_, _Legs_, or _Arms_, maim’d in _whole_ or in _Part_, _Tumours_, _Pustules_, or _Bubos_ about the _Groins_, &c. Which, tho’ _these_ and such like _Accidents_ may verily proceed from either of the forementioned _Causes_; Yet I think, the most common and ordinary _One_, in all Countries, is an impure and unseasonable COPULATION: Such as is not only precisely forbid by the _Express Word_ of _God_[214], but also repugnant to right _Reason_, and even to common _Sense_. FOR who can be so stupid as not to conceive, that this _Menstruous Contagion_, will naturally (tho’ insensibly) creep into the BLOOD, invade the whole _Habit of the Body_, and tacitely infect the very _soundest Constitution_, even sometimes with the _Venereal_ Pox, or perhaps with an _Elephantiasis_, or the _Leprosy_ it self? Nor does this EVIL end always here, but such BIRTHS are also generally as perverse in the MIND, as they are _Heterogeneous_ in the _Person_; for like BASTARDS of _Nature_, they are commonly denudated, or destitute of all her laudable _Gifts_ and _Graces_, which others, her _Legitimate_ SONS, are happily born with and enjoy in Abundance.
