Where a doubt arose about the sense of the original we have followed the authorized French translation of the works of St. Leonard, by Professor Labis of Tournai. The Method of Hearing Mass is taken, with a few additions and corrections, from the translation of the holy and learned Cardinal Gallifet, as here we have a Saint translating the words of a Saint. We hope to see this translation in all the Prayer Books which give this very popular and practical method of hearing Mass.
