My fears not so great as yours & it is by no means cer¬
tain that you are ever to be affected with Stone.
Every precaution however is necessary, as first, the use
of Soap & lime water. Get some of the best Spanish
soap of Castile soap the some of Soap called Castile tho
some of the best is from Alicant. Scrape off & throw
away the outer surface of this to the thickness of
half a quarter of an Inch, then from the inner solid
scrape down the quantity you are to take which
at first may be a dram or the eighth part of an
ounce which scraped small may be swallowed in a spoon¬

ful of water, tea, or garlic as you like best. This
done twice a day but increase by degrees each dose till
double the quantity mentioned, that is a quarter of
an ounce. The Dose is sometimes carried much
farther but this must be as the Stomach bears it
& as it affects the belly more or less. It should never
go farther than giving one stool a day. Every dose
of the Soap should be washed down with a draught
of Lime water which almost every body knows how
to make. The draught with each dose of soap
may be from a gill to half a muchkin and if the
draught with the soap cannot be made conveniently
so large as half a muchkin it would be proper for
you to take a draught of it at other times so
that upon the whole you take at least a muchkin
every day. These remedies will I hope secure
you against concretions either in kidnies or blad¬
der & are also fitted to dissolve any already formed.
For the pain of your back employ the Oil, below,
anointing the pained part every night & morning with it, keeping the part constantly covered with a piece of flannel.
You may judge of the goodness of the oil you get
by this. It should be very white, & should not rea¬
dily separated into an oil & a thinner liquid lying
below.
