As to the _Motion_ of the SEA, its Efficacy upon the _Animal Fabrick_, may be easily comprehended, considering only what is said; together with this Truth, that, at all _Seasons_, the AIR is highest, and the _Winds_ strongest, when the TIDE of the _Flood_ is at its highest Ascent. For as the SEA swells, so the _Ambient_ AIR in 25 Hours, is twice raised to a considerable great _Height_, from the _Attraction_ of the MOON approaching the _Meridian_: And the same swelling of the AIR must necessarily follow, as often as the SUN comes to the _Meridian_ of any place, either above or below the HORIZON; tho’ (as aforesaid) it is always _highest_ at _New_ and _Full_ MOON: And _lowest_ of all, when the MOON is but half _Full_; the _Planets_ then drawing each a contrary way: As it is _middling_, during the Time between the dimidiated _Orbs_ of the MOON, and the _New_ and _Full_ MOON[244]. CONSIDERING then that the _Ambient_ AIR and the surrounding SEA are both _fluid Bodies_, and that the _Changes_ of the ONE agree so exactly with the _Tide_ of the OTHER, we may rationally conclude, that they are both (in a great measure) subject to the same LAWS of _Motion_[245]. Hence it is, that, the great _Physician_[246] says, that the _Fluxes_ and _Refluxes_ of both these ELEMENTS are so ordain’d, by the Wise _Councell_ of the Almighty CREATOR, to keep them from _Stagnations_ and _Corruptions_, which would be noxious to all _Creatures_, that by these means are preferred in a better Condition. Which is also confirm’d by _Experience_, from that, in clear and open places such _Valetudinarians_ as are ready to _Die_, recover their _Health_, and the _Soundest Constitution_ in moist close places, grows SICK. FROM the whole, it is evident, that the _Motions_ of the AIR at the flowing of the SEA, upon the _New_ and _Full_ MOON, and in the _Æquinoxes_, change the _Fabrick_ of the _Animal Bodies_: But these _Changes_ are always most remarkable in those of _weak_ and _sickly Constitutions_; whereas those of _Strong_ and _Healthy Bodies_ more readily repel or evade their _Influences_. Hence it is that our _Bodies_ so much _Sympathize_, and so manifestly _correspond_ with the _Cœlestials_, as the Experience of a great many Ingenious _Authors_ testify[247]: And hence again it is that the HYSTERICK, no less than any _other_ PATIENT, keeps Time strictly with these _Superiour Bodies_, as the _Register_ of a vast many Examples, and even daily _Experience_ it self teaches for Truth. Now having thus far prosecuted the _Diagnosticks_, as well with respect to the _Times_ and _Seasons_ of the PAROXYSMS, as to the _Signs_ and _Symptoms_ of the _Distemper_, I come at length to——
