In addition Saint Francis de Sales devout method of hearing Mass has been added. Also a commentary on the Memorare and the Stations of the Cross. This work is divided into three parts. The FIRST PART embraces a short treatise on the Rosary. A great portion of tbis treatise is extracted from two small Dominican works, written in French, on the Rosary. The division of this little treatise is somewhat similar to Cardinal Lambruschini's treatise on the Immaculate Conception. The SECOND PART treats of Six Reasons for being devout to the Holy Mother of God. The THIRD PART treats of True Devotion to the Divine Mother. It is styled True Devotion to the B. Virgin, in order to distinguish true from false Devotion to her. We cannot be truly devout to her unless we desire to amend our lives, faithfully honor, and commend ourselves to her. But True Devotion to Mary will be more fully explained when we come to the THIRD PART. In this discourse there will be found quotations from some of the most learned and saintly men of almost every age of the Christian era, regarding the Immaculate Mother of God.
