Take venice turpentine and white frankinsence finely powdered and strew
it into your turpentine till it be stiff enough not to run abroad well
mingling it together with a knife then spread it on round pieces of
leather 2 inches and half over for a man & less for children and when
you have spread over your plaister with this liquid turpentine and
frankinsence mingled as before then strew on more of the powder finely
search’d and so let them lay and dry till a white paper will not stick
to them and so puting papers between each plaister lay them up for use
& when you use them warme them and apply them to the navel a little
before the fit comes & let it lay on till they fall off themselves if
one plaister cures not then use a 2^d and so a 3^d but a 1^{st} seldom
fails. Probatum est.
