A Gentiewoman between 40 and 50 years of age, i?i 
the Autumn 97, drank foaie Aluminous. Waters for 
a month or five weeks/ and in a months time after the 
ufe of thefe Watm, found a pain in the Renal region^ 
where fhe never had been aSlifted with any before 5 thrs 
pain returned after the firft Paroxyfm in about a months 
time, and afterwards more frequently, till about the Gr//- 
following it vifited her every day 5 about which rime 
file fen c for me 5 and had when I came to her the Symp- 
toms of a Stone in her Left Kidney, viz, a grinding, and 
fometimes- a very acute pain on that fide of the Spina, 
Dorfij a Vomiting, her Urine during the Paroxyfm tinged 
with Blood, and in it Bloody Riimmtcii^ but what molt 
furprized me, a dozen at leaft of Hjdaiides, fome of tfie 
biggeft of them i h inch long,, their circiimterence equal- 
led that of an ordinary Goofe-qoill 5 in fhape they exact- 
ly reprefented the VejicnU N^tr^oris m Fiih, growing 
fmaller about the middle, as r ofe generally do, and 
were filled frith a Liquor, whicli my tafte and foiell made 
me believe to be Urine 5 I never difcovered any Pus in 
her Urine, nor had (he any ; iin at the Sphindter of the 
-Bladder, nor in the Meatus 'Vrlnar^MS, either before, at, 
or after making Urine. . The Paroxyfm lafted generally 3 
or 4 hours ^ as foon as thefe Hjdatides came away, (which, 
they did not all at once making water, but at feveral 
timesj the pain in her Back, &c. abated very fenfibiy, 
and (he continued eafie and well the reft of tlie day, ex- 
cepting an external forencfs, which the pain had-caufeJ.
