Infernal medicine

Mark Fisher, the master of the workhouse at Bluntisham, in Huntingdonshire, and several of the poor under his care, being troubled with the itch, he mixed a quantity of arsenic, Roman vitriol, glass, and soap, into an ointment, and anointed himself and five women with it. But this his infernal medicine proved so violent, that himself, and two of the women soon died of it, leaving the other three in a very deplorable condition.
