Diftilled Vinegar is aftronger vegetable Acid ; but, 
mixt with the Water, procures no Alteration. 
Spiritus Salts, Nitri , and Vitrioli , the three 
ftrongeft and pared mineral Acids, being mixt with 
the Mineral Water, there was no Change or Preci- 
pitation. 
Mercurius fublimatus corrofivus , is a Diflolution 
of Quickfilver in concentred Spirit of Salt, which, 
being diflolved in common diftilled Water, mani- 
fefted not only the volatile, but alfo the fixed alcaline 
Salt, in any Liquor, infomuch that it precipitates 
the Volatiles to a white , and the fixed alcaline Salts 
to a red Powder 5 but, mixt with this Water, pro- 
duced no Precipitation. 
Vitriolum Martis is an acid Salt, intimately mixt 
with Iron- earth : Being dilfolved, and put into an- 
other Liquor, it will prefently betray the alcaline 
Salts by precipitating them ; but fhould it find no 
contrary Salt, then fomewhat of the Iron-earth will 
fettle to the Bottom 5 as is common in diifolving all 
forts of Copperas: And fo it happened by mixing this 
Mineral Water with it, when a brown Powder fettled, 
which is the Terra Martialis . 
All thefe Experiments fhew evidently, that no 
alcaline Salt is in the faid Mineral Water. 
For, to try whether there is any acid Salt to be 
found in this W ater,the following Mixtures were made : 
Aopna Calcis Viva, which contains an Earth im- 
pregnated with alcaline Salt , makes a very quick 
Difcovery of an Acid , by Precipitation ; bur, mixt with 
this Water, caufed no Variation. 
Syrupits Violanim , having a very fenfible vegetable 
Tin&ure, which, by mixing it with a finall Quantity 
of
