but found no ftone or gravel in the bladder j. that 
part appearing to be, in every refpedl, in a natural 
ftate, except at the neck, where the coats feemed to 
be fchirrous, and were about a quarter of an inch 
thick. 
It is probable, that the ftone had been of a fofter 
texture, and more eafily diftolved, than ordinary ; 
otherwife five or fix drachms of foap taken daily, even 
for fo long a time, could not have diftolved it intirely; 
for many have ufed that medicine in much larger 
dofes, and at the fame time have drank lime-water 
plentifully, without obtaining fucli effects ; tho’ all 
their painful fymptoms were removed by that courfe, 
as Dr. Whvtt has fhewn in his treatife on this fubjedt. 
I fhall only add, that Mr. Simfon’s fon, who is 
now minifter at Fala, was prefent at the opening of 
the body, and can atteft, that there was no ftone 
found in the bladder.
