likely, that the A&ion of the Fire may divide and di£ 
fipate thele into Minuter Particles, and thereby deftroy 
the Texture that makes them hurtful and by caufing 
innumerable tumblings and ravings among the more 
earthy Particles, give them opportunity to make little 
Coalitions, whofe weight precipitating them to the bot- 
tom, frees the pure Water from them. 
And becaufe 'tis but too probable, that the unwhol- XVL 
fomnefs of divers Waters proceed, not only, or per- 
haps not fo much, from bare Crudity, as from a 
great quantity of grofler Particles, that are not ea- 
lie to be rais'd, becaufe of their being combin'd with 
fixt and earthy ones, that fwim up and down in the 
Water they impregnate, as Silver or Mercury does 
in a Solution made with Aquafortis, or rather 3s the 
Particles of Salt do in Pump-water, and many other 
cortimon Waters : On this account I fay, the Patentees 
Invention may very much correct fuch Waters, fince by 
their way of fweetningthofe Liquors, the truly Aqueous 
Parts are not only freed from the Saline ones, but from 
the Mineral, and other grofs and hurtful Corpufcles that 
may have lain cooceal'dm the Liquor. As may be ar- 
gued from hence, that having purpofeiy in the gentle 
Fire of a digeftive Furnace, flowly diftill'd off a Pound 
of the Patentees Water, it left us in the Cucurbit fo light 
and thin a Feculency, that the bottom of the Glafe feem- 
ed to be rather fuliied than covered by it • and I did not 
judge that the whole Feculency, if we could have got it 
out, would have amounted to fo much as two Grains.

Reafons, (to which others might be added, if I could in 
few Words confirm Paradoxical ones) that the laft Great
