The same indelible impression has been made in hundreds of cases, and on persons of every variety of temperament and every pursuit, whether engaged in business, science or art, or rapt in holy contemplation. On one occasion Pascal had been thrown down on a bridge which had no parapet, and his imagination was so haunted for ever after by the danger, that he always fancied himself on the brink of a steep precipice overhanging an abyss ready to ingulf him. This illusion had taken such possession of his mind that the friends who came to converse with him were obliged to place the chairs on which they seated themselves between him and the fancied danger. But the effects of terror are the best known of all the vagaries of the imagination. A very remarkable case of the influence of imagination occurred between sixty and seventy years since in Dublin, connected with the celebrated frolics of Dalkey Island. It is said Curran and his gay companions delighted to spend a day there, and that with them originated the frolic of electing "a king of Dalkey and the adjacent islands," and appointing his chancellor and all the officers of state. A man in the middle rank of life, universally respected, and remarkable alike for kindly and generous feelings and a convivial spirit, was unanimously elected to fill the throne. He entered with his whole heart into all the humors of the pastime, in which the citizens of Dublin so long delighted. A journal was kept, called the "Dalkey Gazette," in which all public proceedings were inserted, and it afforded great amusement to its conductors. But the mock pageantry, the affected loyalty, and the pretended homage of his subjects, at length began to excite the imagination of "King John," as he was called. Fiction at length became with him reality, and he fancied himself "every inch a king." His family and friends perceived with dismay and deep sorrow the strange delusion which nothing could shake: he would speak on no subject save the kingdom of Dalkey and its government, and he loved to dwell on the various projects he had in contemplation for the benefit of his people, and boasted of his high prerogative: he never could conceive himself divested for one moment of his royal powers, and exacted the most profound deference to his kingly authority. The last year and a half of his life were spent in Swift's hospital for lunatics. He felt his last hours approaching, but no gleam of returning reason marked the parting scene: to the very last instant he believed himself a king, and all his cares and anxieties were for his people. He spoke in high terms of his chancellor, his attorney-general, and all his officers of state, and of the dignitaries of the church: he recommended them to his kingdom, and trusted they might all retain the high offices which they now held. He spoke on the subject with a dignified calmness well becoming the solemn leave-taking of a monarch; but when he came to speak of the crown he
