than relatively tepid, yet the Water being less cold whilst it is salient, so long it maybe enlarged in Bulk, and hold no longer in the same Quantity. And Heat and Cold, and, if there be any other Ætherial Concomitants, (tho but as tenuious as Magnetismes,) may pass through Sealed Vessels: Some perhaps more easily through some kinds of Vessels than through others; as Light, and the thinnest Flames of Fire: Though Air be commonly the Fuel and Bellowes, and sometimes the Vehicle, yet they pass through Glass, where Air cannot pass; But they pass not through some sorts of Earthen Vessels. And (to insist no longer on words than a swift glaunce upon the By) we use to call them turgid Spirits and rough Spirits, which are sometimes nothing else but a Heat or Cold encentred in the minute Particles of the Liquor; or those Particles broken into sharper Figures; Or that some Air, which hath a far more vigorous Spring than water, is encentred, compressed, and active in or among the parts of Liquor; Or that some part of the Liquor is refined into a more Spiritual and Invisible substance. And that some of these cases, or the like, may fall out in subterranean Streams, and other Liquors, I can demonstrate Experimentally. And then the effect may be this, that the Air, or other Spirits, may be divided in the sealed Vessel from the Water; Or the fervid and tumultuous Spirits may slacken their Springs, or expire; and so the water may grow Languid and ineffectual, either without the falling down of any sediment, or together with it. That these cases do sometimes come to pass, I shall now endeavour to prove.

1. Though the particles of water are so minute, that we cannot discern them with our Eyes, yet by a duller Organ of Sense, even by Feeling, we may distinguish the acute and vigorous particles of Healing Waters, from the Languid and hurtful particles of Common waters. The Healing waters will intermingle with their asperity's such an agreable titillation, as will invite us to rub in, or presse on the cleansings and tersive water; And will, all along, recompense the pain of searching the wound by their active frictions, with such speedy reparations, and such indulgent degrees of sanation, as mitigates the Torment with store and variety of pleasures. Other Common waters, even those of some of the purest and most Chrystaline Fountains, are almost poy-sonous
