If you raise a blister then it must not be broken but take speare grass
and pound a little of the leaves putting a little butter amongst it put
also as much of it as a small nut and that will raise a blister of the
same bigness cut the blister clean away and then put castle soap and
barme as aforesaid to draw it as long as it will yield anything then
after apply the forementioned Salve unto the sore and (God willing)
this will cure the party in time. Probatum Est.
