Ointment of Lead.
Take of olive oil, half a pint; white wax, two ounces; sugar of lead, three drachms. Let the sugar of lead, reduced into a fine powder, be rubbed up with some part of the oil, and afterwards added to the other ingredients, previously melted together, continually stirring them, till quite cold.
This cooling and gently astringent ointment may be used in all cases where the intention is to dry and skin over the part, as in scalding, &c.
