Mezzofanti's opportunities of conversing with foreigners were much increased by his becoming permanently attached to the Library of the University (with which the Library of the Institute had been incorporated by the French) as Deputy-Librarian. This appointment he received on the 28th of March, in 1812. As the chief librarian at this time was the Abate Pozzetti, who, like Mezzofanti, was an honorary professor of the University, and one of his most valued friends, the appointment was especially agreeable to him : and, independently of its other advantages, it became for him, as I said, from the constant passing and re-passing of strangers from every country, a school in which he was able to exercise himself, almost hourly, in every department of his multilingual studies.
