The career of the horseman was indisputably, on his own part, uncontrollable. The agony of his countenance, the convulsive struggle of his frame, gave evidence of superhuman exertion: but no sound, save a solitary shriek, escaped from his lacerated lips, which were bitten through and through in the intensity of terror. One instant, and the clattering of hoofs resounded sharply and shrilly above the roaring of the flames and the shrieking of the winds—another, and, clearing at a single plunge the gate-way and the moat, the steed bounded far up the tottering staircases of the palace, and, with its rider, disappeared amid the whirlwind of chaotic fire. The fury of the tempest immediately died away, and a dead calm sullenly succeeded. A white flame still enveloped the building like a shroud, and, streaming far away into the quiet atmosphere, shot forth a glare of preternatural light; while a cloud of smoke settled heavily over the battlements in the distinct colossal figure of—_a horse_. THE SYSTEM OF DOCTOR TARR AND PROFESSOR FETHER During the autumn of 18—, while on a tour through the extreme southern provinces of France, my route led me within a few miles of a certain _Maison de Santé_ or private mad-house, about which I had heard much, in Paris, from my medical friends. As I had never visited a place of the kind, I thought the opportunity too good to be lost; and so proposed to my travelling companion (a gentleman with whom I had made casual acquaintance a few days before), that we should turn aside, for an hour or so, and look through the establishment. To this he objected—pleading haste in the first place, and, in the second, a very usual horror at the sight of a lunatic. He begged me, however, not to let any mere courtesy towards himself interfere with the gratification of my curiosity, and said that he would ride on leisurely, so that I might overtake him during the day, or, at all events, during the next. As he bade me good-bye, I bethought me that there might be some difficulty in obtaining access to the premises, and mentioned my fears on this point. He replied that, in fact, unless I had personal knowledge of the superintendent, Monsieur Maillard, or some credential in the way of a letter, a difficulty might be found to exist, as the regulations of these private mad-houses were more rigid than the public hospital laws. For himself, he added, he had, some years since, made the acquaintance of Maillard, and would so far assist me as to ride up to the door and introduce me; although his feelings on the subject of lunacy would not permit of his entering the house.
