PREFACE TO THE THIRD ENGLISH EDITION

THE statements made in the Preface to the Second apply with still greater force to the Third Edition. From the many changes, chiefly verbal, that have been introduced, it is hoped that the work will gain in clearness and conciseness. The present Edition, like its predecessor, has had the advantage of being revised by Monsignor Schobel.
