them mgid Sfiritsmd rough Sprits ^ which are fometimes no- 
thing elfe but a Heat or Cold encentred in the minute Particles 
of the Liquor 5 or thofe Particles broken into (harper Figures | 
Orthacfome Air^ which hath a far more vigorous Spring thaa

parts of Liquor 5 Orthat feme part of the Liquor is refined into 
a more Spiritual and Invifible fubftance. And that fome of 
thefe cafes , or the like, may fall out in fubterranean Streams, 
and other Liquors , I can demonftrate Experimentally, And 
then the effedl may be this, that the Air^or other Spirits, may 
be divided in the fealed VelTd from the Water5 Or the fervid and 
tumultuous Spirits niay (lacken their Springs ^ or expire ; and 
fo the water may grow Languid and inefFe6iual;jeither without the 
falling down of any fediment,or together with it. That thefe ca- 
fes do fometimcs come to pafs,! fliall now endeavour to prove.

Bot difcern them with our Eyes, yet by a duller Organ of Senfe , 
evenby Feeling, we may diftingmfli the acute and vigorous par- 
ticles of Healing Waters/rqm the Languid and hurtful particles 
of Common waters. The Healing waters will intermingle with 
their afferitys fuch an agreable titiliation, as will invite us to 
rubin^or prefle on the cleanfings and terfive water 5 And will, all 
along/ecompence the pain of fearching the wound by their a{aive
