PREFACE TO THE SECOND EDITION.

The Second Edition of this book on the Sacrifice of the Mass has been carefully revised and corrected. By the kindness of friends, errors were pointed out to me which had crept into the text, and they, it is hoped, have been removed.

Some additions have been made in the body of the book and an Appendix has been added on the Language of the Mass. Many non-Catholics and some well-meaning Catholics are earnest in their demand for the use of the vernacular in Church Services. There can be no objection to the vernacular in Services which are extra-liturgical ; but we have endeavoured to show that the law which prescribes Latin as the language of the Mass in the Western Church is another proof of the wisdom more than human which guides her counsels.
