of two months after ufing the foap he was able to go 
a hunting. However, for fome time I was afraid to 
try the foap, not knowing what effects it might have 
on a confirmed ftone ; Sir Alexander Gibfon’s cafe 
being only that of fmall ftones. But the Rev. Mr. 
Lundie, of Salton, by experiments convinced me of 
the efficacy of foap in difiolving a confirmed ftone 
out of the bladder ; for the ftone gradually grew 
fmoother and fmoother, and at laft was quite dif- 
folved. 
On the 1 2th of February 1739, I firft began the 
ufe of the foap, and in the beginning took only a 
drachm in the 2.4. hours. The firft week it made 
me a little qualmifh : however, I gradually increafed 
the dofe ; fo that in fix weeks I took fix drachms a 
day, without its difagreeing in the leaft with me. I 
made it up into pills, and waflied them down with 
a draught of warm milk and water. 
From the time I began to ufe the foap, my gra- 
velifh fymptoms gradually abated j but, upon walk- 
ing two or three miles, I made bloody urine. How- 
ever, that fymptom gradually abated ; and in the 
year 1743 all the fymptoms of a ftone quite vanifhed, 
infomuch that I could walk, ride, or go in a ma- 
chine, as well as ever. 
From February 1739, to July 1743, I took every 
day five or fix drachms of foap : but after that time I 
diminilhed the dofe to half an ounce ; and never 
after had any return of a gravelifh fymptom, tho’ I 
ftill imagine the ftone is not intirely diflolved ; for, 
after fitting fome time, I find as it were fomething 
come to the neck of the bladder; but which gives 
me no uneafinefs.
