drink of thciti«TheSeminal fubftance of ftonySalt is made nitrous, 
fu!phureous,cauftique and rcfolutive by the fire, which was able 
to exalt it, but not able to produce it in calcining thefe ftones, no 
more than that of burnt Ihels of Oy fters , of which alfo a Inne is 
niade» which hath not lefs of fulphureous fak in it. This eaibrio- 
nated fait in lime-ftones is a ftony juice,which may mix it felf with 
the waters that pafs between the beds & interfticcs of thofe ftones 
in the rocks , but which is not eafily difcerned in waters that are 
impregnated therewith. 
The SeminalBeing of Mum and that of FifriolmuH al fo be in the 
matters from whence thefe fpecies of Salts are excrafied by the 
means of water , after their calcination in the Fire, aud their ma- 
ceration in the Air, The Fire and Air that have exalted them^could 
not produce them. Neither the feminal fub/lanceof AlUim in A- 
luminous ftones,nor that of Vitriol in fulphureous marcafices, are 
in that ftate manifefl to our fenfes and ofi en they come not to be 
linown in Mineral waters but by fomeefFeds, and that without 
certainty, becaufe thofe may beequivocal. 
All thefe varieties of Mineral falts, embrionate , form'd , cry- 
ftallin, juicy /ulphureous,non- fulphureous, of the firft and fecond 
concretion; thofe of their genus's, fpecies's, mixtures, proporti- 
ons, alterations , ^c. render difficult and uncertain the judgment 
concerning the proprieties of the waters that parrakeof ihem. 
Again, concerning thofe Subtile Earths ^v^hich do alfo mixe 
themfelves in Mineral waters, they may alfo be of different f rts, 
difficult to difcern : Some of them are found of different colours, 
white, gray,ye]lowifli, reddifli, brownsand of different qualities, 
fome being diffbluble in diftilled Vinegar , others indiffolublej 
fome fufible, others not fufible by the fire, where they take feve- 
ral colours; fome are marly, others argillaceous , others creta- 
ceous^ fome bolar,fomefandy,fometalky,fomelimy; others there 
are that are produced by the concretion of certain juices , faline 
or fulphureous, others not; fomearefimply mineral, oilers me« 
tallique. Moft of thefe forts not being eafie to be difcerned (epa» 
rately, they will be lefs fo when they are mixt with one another. 
The fimple infufions of certain falphurepus mineral Earth: may 
notably alter the waters of Wells and FountainB, witbr ut havibg 
any thing of thofeEarths remaining in th(dr fediments after diftil- 
lations in like manner as nothing is feen in certain liquours ren*
