A visit to Ferney was an event in a traveller's life. In personal intercourse, Voltaire was, according to the testimony of the king of Prussia, and of every other contemporary, and singularly delightful and entertaining. "You are agreeable in conversation, and instruct and amuse at the same time. You are the most fascinating creature in the world; and, when you choose, no one could resist loving you: your wit and genius are so graceful, that, even while you offend, every one is ready to forgive you." This is the description that Frederic gives of him. Nor did age diminish the lustre of his wit, the vivacity of his spirit, or the alternate gaiety and impressive charm of his conversation. It was only at a distance that his tendency to what the French call _tracasserie_--an inherent love of disturbance--and the vehement, uncourteous, and unfair manner with which he carried on a dispute, made his contemporaries, while they viewed him with wonder and delight, yet alternately fear and censure him. He appeared particularly amiable to those who sought his protection, for he was ever generous in pecuniary points, and lavish of his praises to literary men, as long as they paid worship at his shrine. His intercourse with Marmontel illustrates this subject, and we shall extract his account of his visit to Ferney, as giving a vivid picture of the vivacity, and whimsical and capricious disposition, of this singular man; who in age and suffering was as energetic, active, and enthusiastic as a youth just entering warm and undeceived on the scene of life.
