AND the wise HIPPOCRATES observes[83] that as an exquisite _continual Fever_ ceases within the 7th Day, so an exquisite _Tertian_ has seven _periodical Circuits_; because every _Access_ in the latter, makes up a _Day_ in the former Case. Hence it is manifest that all _Epidemick Diseases_ have their due and regular _Times_[84] of encreasing, continuing, and decreasing; and that These _Laws_ of _Nature_ are so constant and permanent, that however _Fevers_ differ in other Circumstances, they are equal as to the Duration of _Time_; counting according to the _Periods_ or Fits of the _intermitting_, and the continued Number of _Days_ of the never _intermitting Fever_. GALEN[85] further explains _Acute DISEASES_, and calls them _Two-fold_: The _one_ attended with a continual FEVER; such as are _burning Fevers_, _Frenzies_, _Lethargies_, _Pleurisies_, _Squincies_, _Inflammations_, &c. The _other_ without any Fever, such as _Epilepsies_, _Apoplexies_, _Convulsions_, _Palsies_, _Contraction of LIMBS_, _JOINTS_, &c. Now the[86] _Accesses_ and _Crises_ of all _These_ proceed from the _Influence_ of the MOON; which in over-ruling terrestrial Things, surpasses all the other PLANETS and STARS, not so much because of her _Power_, as by her _Approximation_ or _Vicinity_. THE _Cause_ of both the _one_ and the _other_ seems to be the _same_; tho’ it _affecteth differently_, according to the various _Regimen_ and _Disposition_ of the Woman: And it most probably proceeds either from the _vitious Humours_, which have abounded in the Body before _Conception_; or from such _Humours_ as have been congested afterwards by the _suppressed_ MENSES, or _Months_: Which being irritated by improper or depraved _Food_, by bad or negligent _Regimen_, either before or after _Conception_; those _Humours_ (like _Yest_ in _Ale_) ferment the BLOOD, to such a Degree, that (all on a sudden) the PATIENT is violently taken with one or other of those _Acute_ DISEASES, which are determined by a certain _Lunary_ CRISIS; that is to say, by a certain _Motion_ of NATURE, accelerated by the _Power_ of the MOON, to a gradual _Expulsion_ of the _peccant Matter_ thro’ the PORES of the Body. But this CRISIS, in short, happens always with most Ease and Safety upon the _New_ or _Full-Moon_, because the ambient _Air_ does not at that time so much affect the _Superficies_ of the Body, nor so violently repress the _Motion_ of the FLUIDS.
