Put a pound and a half of clear beef marrow into an earthen pan of
fresh water, and change the same for ten days, then steep it in rose
water for 24 hours, and drain it in a cloth till dry. Take an ounce
of storax, gum benjamin, odoriferous Cypress powder, or of Florence,
half an ounce of cinnamon, two drachms of cloves, and two drachms
of nutmeg, all finely powdered; mix them with the marrow, then put
the ingredients into a three-pint pewter pot, make a paste of the
white of egg and flour, and lay it upon a piece of rag, over that,
put another piece of linen to cover the top close. Put the pot into
a large copper pot with water, and keep it steady that it may not
reach to the covering of the pot that holds the marrow. As the water
shrinks, add more, for it must boil four hours without ceasing;
strain the ointment through a linen cloth into small pots, and when
cold cover them up close with bladder and paper. Don’t touch it with
anything but silver.
