SECONDLY, If the _Party labours_ under any of the aforesaid _Causes_ debilitating or impeding the _Retentive_ POWER; _some_ are manifest to the _Woman_ her self; as in the _Cases_ of any immoderate _Flux_, a _slimy_ or _illuvious Evacuation_, a _Gonorrhæa_, the _Whites_, a _Falling_ of the WOMB, _&c._ _others_ are obvious to the MIDWIFE’S _Touch_, as in the _Case_ of _Tumours_, _Ulcers_, &c. and in _Case_ of either _Intemperature_, _Dropsy_, _Inflammation_, _Worms_, &c. all such are abundantly evident to the _Physician_, after duly examining, and considerately weighing the _Disposition_ or _Temperature_ of the whole Body _in general_, and of the WOMB in _particular_. THIRDLY, if the _Alterative_ or _altering Faculty_ be læs’d or impotent, then, after some Days _Retention_, an _Effluxion_ of the _SEED_ happens, and that either because of some _Intemperature_ of the WOMB; or of some discording _Quality_ in the _SEEDS_, or in the WOMB, as above; or lastly, because of a _Want_ or _Scarcity_ of BLOOD for forming the FOETUS. As to the _Intemperatures_, I have already observ’d, that, they may be readily distinguished by the ingenious _Physician_; But the _Disproportion_ betwixt the commixed _SEEDS_, or between _these_ and the WOMB, how much, and in what they may differ _one_ from _another_, is not so easily known; because this _Fault_ may be as much in the MAN, or perhaps more, than in the WOMAN, as has been already hinted: In this _Case_, the _Physician_ is to weigh and consider well the _Temperatures_ of the whole Body, and especially _that_ of the _Genital Parts_ of both the MAN and the WIFE; and as much as possible, to reduce _that_ of the _One_, to the more convenient _Temperature_ of the _Other_,[228] correcting _Both_ in what may be found requisite; according to the Direction of _Lucretius_, in these _Verses_: _“Usq; adeo magni refert, ut Semina possint “Seminibus commisceri generaliter apta, “Crassáq; conveniunt liquidis, & liquida crassis._ FOURTHLY and lastly, if the _Nutritive Faculty_ be faulty, the _Case_ is plain and manifest; since it generally proceeds from one or more of the following _Causes_, _viz._ from _Want_ or _Penury_; a _Pining away_ or _Consumption_; immoderate _Hæmorrhagies_, whether happening by _Superiour_ or _Inferiour Parts_; hard _Labour_; too much _Fat_, or too much _Leanness_: As the same may also happen from an _Obstruction_ or _Suppression_ of the MENSTRUOUS COURSE; or from its vicious or impure _Quality_; and, in fine, from any severe _Symptom_ or _Disease_ whatsoever.
