nowned as the patron of learning. He presented himself in his travelling attire in the presence of that monarch and his courtiers; and, without invitation, coolly sat himself down on the sofa beside the prince. The courtiers and wise men were indignant; and the sultan, who did not know the intruder, was at first inclined to follow their example. He turned to one of his officers, and ordered him to eject the presumptuous stranger from the room; but Alfarabi, without moving, dared them to lay hands upon him; and, turning himself calmly to the prince, remarked, that he did not know who was his guest, or he would treat him with honour, not with violence. The sultan, instead of being still further incensed, as many potentates would have been, admired his coolness; and, requesting him to sit still closer to him on the sofa, entered into a long conversation with him upon science and divine philosophy. All the court were charmed with the stranger. Questions for discussion were propounded, on all of which he shewed superior knowledge.

One of the doctors present inquired whether a man who knew so many sciences was acquainted with music? Alfarabi made no reply, but merely requested that a lute should be brought him. The lute was brought; and he played such ravishing and tender melodies, that all the court wore melted into tears.

The sultan, highly delighted with his powers, entreated him to stay, offering him every inducement that wealth, power, and dignity could supply; but the alchymist resolutely refused, it being decreed, he said, that he should never repose till he had discovered the philosopher's stone. He set out accordingly the same evenings and was murdered by some thieves in the deserts of Syria. His biographers give no further particulars of his life beyond mentioning that he wrote several valuable treatises on his art, all of which, however, have been lost. His death happened in the year 954.
Avicenna.
Avicenna, whose real name was Ebn Cinna, another great alchymist, was bom at Bokhara in 980. His reputation as a physician and a man skilled in all sciences was so great, that the Sultan Magdal Douleth resolved to try his powers in the great science of government. He was accordingly made Grand Vizier of that prince, and ruled the
