Mr L. TREVIGAR’s CASE. 463

till May 1755, at which time I was taken ill with the haemorrhoids
to a very great degree ; and as I was finished the fymptoms of this
diforder were greatly increafed by the foap, I was obliged to difcon-
tinue it, and indead of drinking one pint of lime-water every day
with the foap, I now drink, and have done ever fince May 1755,
three pints without it, a lefs quantity not being diffident to keep
me clear of the gravel. But by continuing this quantity of lime-
water, even without any foap at all, I am perfectly eafy, and have
been fq ever fince May 1755 ? anc^ indeed have I been ever fince I
fird took the foap, having never been troubled with one fit for thefe
four years pad, or had any fymptoms of any {tone's forming either
in my kidneys or bladder.
As I have, in the foregoing cafe, mentioned Mr Hay, it may not
perhaps be unfeafonable to take notice, that this gentleman died a-
bout a year ago, and his body, according to his own requeft, was
opened. I was not prefent myfelf at the diffedtion, but received an
exadt account of every particular from a gentleman of the faculty
who was there, and attended with great accuracy to every part, ex¬
pecting to find very extraordinary diforders occafioned by the im-
menfe quantity of foap taken. (I have heard Mr Hay himfelf fay
he had taken frequently three ounces in a day). But upon exami¬
nation, no diforder was difcovered that could be attributed to the
foap. There was indeed a little extravafation in the vi/cera; but
that, I am told, is no uncommon appearance, when people die of an
apoplexy, as Mr Hay did ; in all other refpedls he was perfedtly
found there. In his bladder was found a done wrapt up with part
of the coat on the left fide, which formed a fort of purfe for it, on¬
ly the neck of the purfe was open for the urine to pafs into it. I
faw and examined the done myfelf ; it was exceeding hard, but
perfectly fmooth, of the colour of a dark mohogany, and in the
form of a convex lens, the didance between the two convexities be¬
ing half an inch nearly. The breadth over was fomewhat more than
an inch and a quarter. There was not the lead appearance of any
corrofion, but probably the foap kept it fmooth, and prevented its
wounding the bladder, as it had before done; for from the time of
his taking the foap, he was perfectly eafy to his dying day.
