"These poultices should be changed occasionally, keeping the first kind on about one third of the time, and the maycock the other two-thirds."
"(For the mode of preparing this ointment, look under its proper head.) -- It should be annointed with this ointment every twelve hours, then apply a plaster made of equal quantities of common soap, and table salt, mixed well together; the fourth day this poultice should be changed, for one made by boiling the pulverized root of maycock in water, and thickening it with corn meal."
