Bayley and Haskins remained in Rome for more than a month. Together, they visited the rooms that had been occupied by St. Philip Neri, St. Stanislaus Kostka, and St. Aloysius Gonzaga, with Bayley writing in his journal, "there are no places in Rome that I have visited with more pleasure than such spots hallowed by the memory of departed virtue." They also paid a number of visits to the Urban College of the Propaganda, where Bayley became friends with William O'Hara, James Andrew Corcoran, and his fellow convert James Frederick Wood. On one occasion, Bayley and Haskins went to the room of Giovanni Perrone at the Roman College and spent "a short time in very pleasant conversation with him." On another day, they paid a visit to Giuseppe Mezzofanti, famed for his fluency in thirty-eight languages, who impressed Bayley as "a humble minded good old man." On May 30, accompanied by Father Esmonde, they went for an audience with Pope Gregory XVI.
