This biography is a charming one, translated in the inimitable English idiom of the 17th century. Father Aylward has very successfully imitated the antiquated style in his valuable preface. The biography leaves nothing to be desired as a history of the private, interior life of the saint, though her wonderful public career is but slightly touched upon. The sketch of it in Father Aylward's preface induces us to wish that he would add to the history of Saint Catharine's private life by Caterinus, an equally complete history of her public life, with translations of her letters, from his own graceful and devout pen, which would furnish the English public with one of the best and most valuable biographies of a truly great and heroic woman to be found in any language. ---- {143} Prayer the Key of Salvation. By Michael Müller, C.S.S.R. Baltimore: Kelly & Piet. 1868. This book is an expansion of the excellent work of St. Alphonsus Liguori on Prayer. The object of it seems to be, to explain the saint's doctrine and illustrate it by examples, so as to bring it more within the comprehension of the mass of the people. But we are sorry to be obliged to say that the execution of the work does not come up to the idea. Without commenting on the matter, which is, in general, very good, we are compelled to say that the style is faulty in the extreme; the sentences are mostly un-English in their construction, and sometimes so long and involved that they are hard to understand. It also abounds in grammatical errors. In short, it is a pity it was not first thoroughly overlooked and revised by a competent hand before being allowed to go to press. However much we may desire to commend this book, we cannot in conscience do so, so long as it continues in its present dress. ---- La Reforme en Italie, les Precurseurs: Discours Historiques de César Cantu.
