Id reference to the internal Ufe of thefe Waters, I 
drank about a Quart at a time, after this rr/anner. I 
firft began with ihQ Spiirv Waters, which \ r?rocurd very 
good, and drank them fora Week, and they agreed very 
well- 8 then drank thePymm Warers for three or four 
Days, and continu’d the ufe of thefe Waters alternately, 
until I had drank about twenty Days. By the refult of my 
Experiment it feem’d to me very plain, that the Pjrmont 
Water was more agreeable, gave more Strength and 
Spirit, and was as much or more preferable for its internal 
Vertue, as for its excelling the other in a brisker and 
more fprightly Tafte. 
There is another Excellency in thefe Waters whicli 
will make them more ufeful to us, than any Foreigir 
ChdlyhfAt Waters we yet l^ow, becaufe thele will keep 
better ; they are not fo foon fpoil’d by any accidental 
Infinuations of Air, as tbeSpan> are fubjedt to be. The 
Chalybedt Mineral is here throughly diflblved and well 
united, and mix’d in this Water, fo that it does not 
eafily precipit^er. for which Reafon it may alfo the 
better pafs the vafa U5iea^ and even enter into the Mafs 
of Blood it felf, and work the more confiderable Effeds. 
That this is not a bare Hypothefis may be prov’d by 
this Experinaent. 
Having fufferd the Spdw Water co be expofed in a 
Bottle which was half full, and unftopc iz Hours,.! 
examin’d it, and found it taft juft like common Wa- 
ter; but the Pyrmom Waters that were open’d to the 
Air after the fame Manner, tafted ftrong of the Mine- 
ral, and gave their Tindure as at firft; nay, they coii' 
tinued thus for full two Days, and perhaps might have 
done longer, buE.,1 thought chat TimefUffied.
