Suddenly disgusted with the world and with myself, weary, discouraged, mistrusting men, (ay, and women, too,) I fled to a desert on the extinct volcano of M----, where, for several months, I lived the life of a cenobite, with no companion but a poor lunatic, whom I had met on a small island, and who had attached himself to me. He followed me everywhere, and loved me with that absurd and touching constancy of which dogs and madmen alone are capable. My friend, whose insanity was of a mild and harmless character, fancied himself the greatest genius in the world. He was, moreover, under the impression that he suffered from a gigantic, monstrous tooth. Of the two idiosyncrasies, the latter alone made his lunacy discernible,--too many individuals being affected with the other symptom to render it an anomalous feature of the human mind. My friend was in the habit of protesting that this enormous tooth increased periodically and threatened to encroach upon his entire jaw. Tormented, at the same time, with the desire of regenerating humanity, he divided his leisure between the study of dentistry, to which he applied himself in order to impede the progress of his hypothetical tyrant, and a voluminous correspondence which he kept up with the Pope, his brother, and the Emperor of the French, his cousin. In the latter occupation he pleaded the interests of humanity, styled himself "the prince of thought," and exalted me to the dignity of his illustrious friend and benefactor. In the midst of the wreck of his intellect, one thing still survived,--his love of music. He played the violin, and, strange as it may appear, although insane, he could not understand the so-called _music of the future_.
