Pomet (1694) says he had been informed by Moses Charas, who had lived for some time in England, that "The London druggists sell skulls of the dead upon which there has grown a little greenish moss called Usnea, because it resembles the moss which grows on the oak. These skulls mostly come from Ireland, where they frequently let the bodies of criminals hang on the gibbet till they fall to pieces."

But he adds the useful comment, "This Magistry is only a dead-head of no virtue unless you employ the skull of a young man who died a violent death."
In a paper "On the Deaths of some Eminent Persons," printed by Sir H.
