On the Good Fridays of each year the chapel scarcely sufficed to contain the crowds of sick persons who flocked to it from all parts of the city. All maladies were supposed to be curable through the virtues of the holy relics, but specially that known formerly as _le mal caduc_. At midnight the relic of the True Cross was exposed, and at the same moment the chapel was filled by the most fearful shrieks of these poor epileptics. The afflicted threw themselves about, foamed at the mouth, and fell into convulsions, invoking the aid especially of S. John the Baptist and S. Spire. The people were convinced every year that some wondrous miracle had been wrought; but the abuses connected with this nocturnal exposition were so great that, in 1781, Louis XVI. ordered it to be discontinued. The relics now shown in the Treasury of Notre-Dame, and exposed there during Holy Week, are said to be the veritable ones belonging to the Sainte-Chapelle; but the account of their preservation after the desecration of S. Denis is so miraculous (almost as much so as the original finding of the True Cross by S. Helena) that it requires a large amount of faith to believe in them. The reliquaries were of course all melted up, even Alexandre Lenoir could not save them. Those at Notre-Dame are quite modern, although somewhat of the same form. Another custom peculiar to the chapel was the singing upon Christmas-day of the hymn "_Noël_," in place of "_O Salutaris Hostia_." The former had been originally a joy-song, welcoming the kings upon their entry into Paris; and thus, when our Henry V. entered the capital in 1420, and likewise Henry VI. in 1431, they were greeted with this exclamation.
