there appeared any A!lut», or true Vitriol, except the water of 
Vabls in Daufhine^ which yielded a falc that had forae refemblance 
lo white Vitriol. 
They take notice^ that they didnotmudi apply themfelves to 
obferve the icrms ^v^AFig^res of each of thofeSalts they met with 
in their condenrationsjbecaufc they found them vary in the farm 
Salts, according to the manner and degree of the evaporation of 
the water wherein they were diffblved for refinement. 
As to the Earths that were found in different quantities in the 
waters here examin'd ; they acknowledglikewife, that the parti- 
cular difcernment of their ffecies^s was yet lefs eafie than that of 
the j^ecies of Salts. Some of thofe Earths were white, fome gray, 
fome rediflb; and in the evaporation of all thofe waters, their terre- 
ftrial parts form*d themfelves diverfly ; fome into floting filmes^ 
fome into flocks, fome intomucilagesj others into little clods| o- 
thers into fmall grains of fands ; others into fine brown powder: 
Again/ome dilTolved almoft wholly in diftilled vinegar,with fome 
effervefcence ; fome diffolved but in part, fome not at all; others 
only gave to thediftilled vinegar a high tinSureof hyacinth, w*^^ 
w^as loft in few daies : Again , the fire made fome of thefe Earths 
change colour, others not i and fome of them it calcined, and vi- 
trified others. 
Thefe obfervations of the qualities, quantities, differences and 
agreements of the Salts and Earths of fo many waters, examin'd by 
thefe Phihjofberj^ ( of which a particular Hiftory and account 
is here given)may be very ufeful & ferviceable to thofe Phyfitians 
that advife the ufe of them, the better to make choice of thofe, 
which by reafonof the mixture of thofe more fenfible mineral 
matters may fute with their intentions for the refloring of many 
Patients to their former health. 
For a conclufion of this Hiflory , they give us fome Advertife- 
ments and Corollaries,worthy indeed to be taken notice of 5 as, 
I. That the great quantity of mineral waters,which Phyficians 
make thofe to drink, to whom they prefcribe them for the cure of 
certain contumacious difeafes that will not yield to ordinary re- 
medies, givej^usoccafion to judg, that the chief efFeft, which they 
make us expeft from them,is the cleanfing of the vifcera by this in- 
ternal ablution, : And that this efFeft is confiderable, becaufe mofb 
of Chronical difeafes come from the obflruftionof thtvifcer4, 
which this great quantitie of mineral drink may remove. Mean
