With many other Protestants, he assisted at the exercises of a mission given at Berlin by the Jesuit Fathers, and reaped therefrom much benefit. In July, 1858, he received permission from the minister of worship to explore the libraries of Germany and northern Italy, to collect such manuscripts of Eusebius as might be found, with a view to a new revision of the text of that historian. He visited Leipsic, Dresden, Vienna, Venice, Padua, Milan, and Munich. At Dresden, Wolfgang de Goethe took him to be a Catholic priest. At Venice he met with F. Ignazio Mozzoni, of the order of St. John of God, author of a remarkable history of the Church, and was edified by the piety and the literary activity of the Mechitarists. The intercourse he had with Catholic ecclesiastics, and the sight of Catholic ceremonies and rites, were of signal service to him by removing unfavourable impressions. Among other details he tells us: "I shall never forget a certain Irish Dominican, the very type of a perfect religious, who aroused in me profound emotions by the account he gave me of the sad condition of his fellow-countrymen, crushed by English rule" (p. 191). His scientific mission was finished at Munich, whither he returned from his long journey still a Protestant. But the end was at hand, and we must allow him to describe it in his own words: "After leaving Munich, I continued for some weeks to suffer great anguish of mind. At length the decisive hour came, and the sun of grace had completed the work of my enlightenment.

I communicated my resolutions to the minister of worship and to the faculty of theology of Berlin, and I requested my bishop--the Bishop of Ermland--to receive me into the bosom of the Roman Catholic Church, in which, after long and painful struggles, I had at length recognized the depositary of the truth, and the legitimate spouse of the Son of God: thus would my heart be at peace. 'Glory and praise', said my letter, 'to our Lord Jesus Christ, who has enabled me to surmount all obstacles, who has graciously heard my prayers, who has had pity on me, who has broken my chains, who has scattered the darkness that hung over me, who has shown me the path to the fold. Since conscientious investigations have proved to me that the so-called Reformation of the sixteenth century has but disfigured the type of the true Church of Jesus Christ, and that its principles, far from being salutary, are essentially destructive and the necessary cause of the effects which history has registered during three centuries--that the Protestant confessions and their apologists, instead of attacking the Church's genuine teaching, do but distort it to insure an easy victory; since I am convinced
