A modern writer on Arabic music, as it is practised in Algiers and Tunis, mentions among the various Modes used at the present day a peculiarly impressive one, called Asbein, which the Mohammedans believe to have been especially appropriated by Satan for the purpose of tempting man. They have a long story respecting its origin and demoniac effects. The writer alluded to, a Frenchman, had the gratification of hearing a piece or two played in this Mode by a musician, who had the reputation of being one of the best performers in Tunis, and who used to entertain the frequenters of a certain coffee-house in a suburb. To this place the Frenchman repaired, and induced the musician to play in the Mode Asbein. To surmise from his description of the performance, there must have been something really frightful in the degree of ecstacy which the player exhibited. But there is something funny in the Frenchman's mode of reasoning, which deserves to be noticed, because it shows how opinions like the above are sometimes adopted readily enough even by professed sceptics. The Frenchman was a sceptic, and had made up his mind before he proceeded to examine the matter, that the impression of the Arabs respecting the Mode Asbein was due entirely to their religious enthusiasm. They are, of course, Mohammedans. Now, after the performance, the Frenchman accidentally learnt that the musician was a Jew. Then he no longer doubted the demoniac power of the Mode Asbein. WITCHES. Respecting the music of witches, a few short remarks may suffice. Every one knows that witches, at their meetings, amuse themselves especially with music and dancing. In Germany, the largest assemblages of these objectionable beings take place in the night of the first of May (Walpurgis), and the most favourite resort for their festivities is the summit of the Harz mountain, called Brocken, or Blocksberg. The musicians sit on old stumps of trees, or on projecting rocks, and fiddle upon skulls of horses. Whoever desires to witness these ghastly scenes must provide himself with the upper board of an old coffin in which a knot has been forced out, and must peep through the hole. THE CHANGELING. According to an old superstition, which was widely spread during the Middle Ages, the elves sometimes steal a handsome, new-born child from its cradle, and substitute an ill-formed, ugly child of their own. The little Irish prodigy who is the hero of an event which happened in the county of Tipperary, was such a Changeling. The story told of him, it will be seen, is stamped with the peculiar wildness of fancy which generally characterizes Irish fairy-tales.
