"a fantastic sect of Convulsionists"

The Convulsionists were a body of religious fanatics in France.  Diacre Paris, who had died “protesting with his last breath against the doctrines of the obnoxious Bull Unigenitus,” became a martyr to a particular sect of Catholics.  He was buried in 1727 in the small church-yard of St. Medard, in the twelfth arrondissement of Paris.  The Convulsionists of St. Médard were so named because they went into violent convulsive movements when they touched, or even approached, his tomb, in the years following his death.
