It was doubtless to the lessons of his early master, Father Thiulen, that he owed the knowledge of Swedish which enabled him to converse with General Groben. A still more distinct evidence of his familiarity with it occurred on occasion of the visit of the Crown Prince (now King) Oscar of Sweden to Bologna. M. Braunerhjelm, now Hof-Stallmastare at Stockholm, who was present at the prince's interview with Mezzofanti, assured Mr. Wackerbarth, who was good enough to make the inquiry for me last year, that "the abate spoke the language quite perfectly." According to another account which I have received, the prince, having suddenly changed the conversation into a dialect peculiar to one of the provinces of Sweden, Mezzofanti was obliged to confess his inability to understand him. What was his amazement, in a subsequent interview, to hear Mezzofanti address him in this very dialect! " From whom, in the name of all that is wonderful, have you learnt it ?" exclaimed the prince. "From your Royal Highness," replied Mezzofanti. " Your conversation yesterday supplied me with a key to all that is peculiar in its forms, and I am merely translating the common words into this form."
