composed of these simple ingredients: Butter, lard, Venice turpentine,
white wax and yellow wax. Here is a rule for another ointment: Fresh
butter, three-quarters pound; beeswax, four ounces; yellow resin, three
ounces; melt together; add vinegar of cantharides, one fluid ounce; and
simmer the whole with constant agitation for ten or twelve minutes, or
until the moisture is nearly evaporated; then add of Canada balsam one
ounce; express oil of mace, one drachm; balsam of Peru, ten or twelve
drops; again stir well, allow mixture to settle; and when about half
cold pour into pots previously slightly warmed, and allow it to cool
very slightly. There is nothing else but to put on your label and expose
for sale.
