There is such an Antipathy betwixt Water and Fire, (I mean bright shining Fire) that they never meet Body to Body, but Fire is in danger to be quenched out, if there be a sufficient Quantity of Water. But it is to be observed, That it is not the actual Coldness of Water, that quenches out Fire; for, Scalding-water will quench out Fire: wherefore, it is the Wetness that quenches out Fire; which Wetness choaks the Fire, as a Man that is drown'd: for, Water being not fit for Man's Respiration, because it is too thick, choaks and smuthers him; and the same doth Water to Fire: for, though Air is of a proper temper for Respiration, both to some sorts of Animals, such as Man; as also, to Fire: yet, Water is not: which is most proper for other sorts of Animals, namely, Fish; as also, for some sorts of Animals that are of a mixt kind or sort, partly Fish, and partly Flesh: to which sort of Creatures, both Air and Water are both equally proper for their Respiration; or, their Respiration equal to either: for certainly, all sorts of Creatures have Respiration, by reason all Creatures subsist by each other; I say, By each other, not Of each other. But, there are many several sorts and kinds of Respirations; as concerning Water and Fire, though a sufficient quantity of Water, to Fire, doth always choak, smuther, or quench out the Fire's Life, if joyn'd Body to Body; yet, when there is another Body between those two Bodies, water is in danger to be infected with the Fire's heat; the Fire first infecting the Body next to it; and that Body infecting the Water: by which Infection, Water is consumed, either by a languishing Hectick Fever; or, by a raging Boyling Fever; and the Life of Water evaporates away.
[CHAP. XXIII. Of Inflamable Liquors.]
There are many Bodies of mixt Natures; as for example, Wine, and all Strong Liquors, are partly of a watry Nature, and partly of a fiery Nature; but, 'tis of that sort we name a Dead, or Dull Fire: but, being of such a mixt Nature, they are both apt to quench Bright Fire, as also, apt to burn or flame; so that such sorts are both Inflamable, and Quenchable. But, some have more of the fiery Nature; and others more of the watry Nature; and, by those Effects, we may perceive, that not only different, but opposite Figurative Motions, do well agree in one Society.
[CHAP. XXIV. Of THUNDER.]
I observe, that all Tempestuous Sounds have some resemblances to the flowing of waters, either in great and ruffling waves; or, when the waters flow in such sort, as to break in pieces against hard and rugged Rocks; or run down great Precipices, or against some Obstruction. And the like Sound hath the Blowings of Wind, or the Clappings of Thunder; which causes me to be of opinion, That Thunder is occasioned by a Discord amongst some Water-Circles in the Higher Region; which, pressing and beating upon each other in a confused manner, cause a confused Sound, by reason all Circles are Concave within the Bow, and Convex without; which is a Hollow Figure, although no Vacuum: which Hollow Figure, causes quick Repetitions and Replies; which Replies and Repetitions, we name Rebounds but, Replies are not Rebounds; for, Rebounds are Pressures and Re-actions; whereas Repetitions are without Pressure, but Re-action is not: and, Replies are of several Parts; as, one Part to reply to another.
But for Thunder, it is occasioned both by Pressures and Re-actions; as also, Replies of Extended Water-Circles, which make a kind or sort of Confusion, and so a confused Sound, which we name Horrid; and, according to their Discord, the Sound is more or less terrifying, or violent. But this is to be noted, That as Thunder is caused by undivided or broken Circles; so Lightning is caused by broken or divided Circles, that are extended beyond the Power of the Nature of the Water-Circle; and when the Circle is extreamly extended, it divides it self into a straight Line, and becomes a flowing Flame.
