The devotion of the Holy Rosary is one of the most beautiful which the Catholic Church proposes to her children, and is also probably the one which has been received by them everywhere, without distinction of nationality or class, with the most sincere delight. Catholics, it is true, are for the most part familiar with the general history and significance of this devotional practice, which in itself forms a compendium of popular theology. Most of the books, however, on this subject, with which we are acquainted, are intended to excite Christians to the frequent and devout use of this form of prayer, rather than to give them a full and clear understanding of its natural connection with the great and fundamental truths which form the basis of Christianity. The book of F. Formby is both doctrinal and devotional; all the more devotional because the piety which it inculcates is enlightened by true Christian science. The work is divided into three parts corresponding with the three groups of mysteries of which the Rosary is composed. The author prefaces each of these groups with an introduction, in which he carefully compares its mysteries with their corresponding types in the Old Testament. This comparison is again instituted in a more particular manner as each mystery in turn presents itself for elucidation. In treating of the different mysteries, he first quotes from Scripture those passages upon which they are formed, and then adduces the corresponding types from the Old Testament, still further illustrating the subject by apposite quotations and allusions taken from the classics of pagan literature. These are followed by extracts from the writings of the great Fathers and Doctors of the church, many of which will be new to the English reader. Thus each chapter of the book forms a comprehensive treatise, both doctrinal and devotional, of the particular mystery in the life of our divine Saviour or that of his Blessed Mother to which it is devoted. Without going out of his way, F. Formby by the simple exposition of the doctrine and practice of the church shows in the most conclusive manner how utterly groundless are the objections of Protestants to Catholic devotion to the Mother of Christ. We have not for a long time read a book with which we are so perfectly pleased as with this of F. Formby. The clergy especially will find in it a rich mine from which to draw instruction for the people. It may be read with profit, however, by all classes of persons, as the plain and simple style in which it is written does not raise it above the comprehension of even uneducated minds. The book is ornamented with thirty‐six full‐page woodcuts, unusually excellent both in design and execution; which, added to the attractions of clear typography and tasteful binding, make it a work of art as well as of religion.
