“ In Paris, before the passage of the Associations Law, the Nocturnal Adoration was practised in upwards of one hundred and thirty churches and chapels by more than twenty-five hundred men. The Nocturnal Adoration, at Rome, founded in 1851, and erected into an archconfraternity in 1858, practically completes the chain of associations that render perpetual, in a strict sense, the adoration of the Blessed Sacrament. It would be impossible to give here an adequate notice of the enormous number of Eucharistic associations, lay and clerical, formed for the work of the Perpetual Adoration. ”
