"My visions," he said, "commenced two or three years since, when I found myself from time to time embarrassed by the presence of a large cat, which came and disappeared I could not exactly tell how, till the truth was finally forced upon me, and I was compelled to regard it as no domestic household cat, but as a bubble of the elements, which had no existence save in my deranged visual organs or depraved imagination. Still I had not that positive objection to the animal entertained by a late gallant Highland chieftain, who has been seen to change to all the colours of his own plaid if a cat by accident happened to be in the room with him, even though he did not see it. On the contrary, I am rather a friend to cats, and endured with so much equanimity the presence of my imaginary attendant, that it had become almost indifferent to me; when, within the course of a few months, it gave place to, or was succeeded by, a spectre of a more important sort, or which at least had a more imposing appearance. This was no other than the apparition of a gentleman-usher, dressed as if to wait upon a Lord Lieutenant of Ireland, a Lord High Commissioner of the Kirk, or any other who bears on his brow the rank and stamp of delegated sovereignty. "This personage, arrayed in a court dress, with bag and sword, tamboured waistcoat, and chapeau-bras, glided beside me like the ghost of Beau Nash; and, whether in my own house or in another, ascended the stairs before me, as if to announce me in the drawing-room, and at sometimes appeared to mingle with the company, though it was sufficiently evident that they were not aware of his presence, and that I alone was sensible of the visionary honours which this imaginary being seemed desirous to render me. This freak of the fancy did not produce much impression on me, though it led me to entertain doubts on the nature of my disorder and alarm for the effect it might produce on my intellects. But that modification of my disease also had its appointed duration. After a few months the phantom of the gentleman-usher was seen no more, but was succeeded by one horrible to the sight and distressing to the imagination, being no other than the image of death itself--the apparition of a _skeleton_. Alone or in company," said the unfortunate invalid, "the presence of this last phantom never quits me. I in vain tell myself a hundred times over that it is no reality, but merely an image summoned up by the morbid acuteness of my own excited imagination and deranged organs of sight. But what avail such reflections, while the emblem at once and presage of mortality is before my eyes, and while I feel myself, though in fancy only, the companion of a phantom representing a ghastly inhabitant of the grave, even while I yet breathe on the earth? Science, philosophy, even religion, has no cure for such a disorder; and I feel too surely that I shall die the victim to so melancholy a disease, although I have no belief whatever in the reality
