But the action of morbid impulses and desires is far from being confined to things material. Witness the occurrence of my dream, which, though a dream, was true in spirit. More speeches, writings, and actions of humanity have their result in morbid impulse than we have an idea of. Their territory stretches from the broadest farce to the deepest tragedy. I remember spending an evening at Mrs. Cantaloupe's, and being seized with an impulse to say a very insolent thing. Mrs. Cantaloupe is the daughter of a small pork butcher, who, having married the scapegrace younger son of a rich man, by a sudden sweeping away of elder brethren, found herself at the head of a mansion in Belgravia, and of an ancient family. This lady's pride of place, and contempt for all beneath her, exceeds any thing I have ever yet seen or heard of; and, one evening, when she was canvassing the claims of a few _parvenu_ families in her usual _tranchant_ and haughty manner, an impulse urged me to cry, at the top of my voice: "Madam, your father was a little pork-butcher--you know he was!" In vain I tried to forget the fact; in vain I held my hands over my mouth to prevent my shouting out these words. The more I struggled against it, the more powerful was the impulse; and I only escaped it by rushing headlong from the room and from the house. When I gained my own chambers, I was so thankful that I had avoided this gross impertinence that I could not sleep. This strange thralldom to a morbid prompting not unfrequently has its outlet in crimes of the deepest dye. When Lord Byron was sailing from Greece to Constantinople, he was observed to stand over the sleeping body of an Albanian, with a poniard in his hand; and, after a little time, to turn away muttering, "I should like to know how a man feels who has committed a murder!" There can be no doubt that Lord Byron, urged by a morbid impulse, was on the very eve of knowing what he desired; and not a few crimes have their origin in a similar manner. The facts exist; the evidence is here in superabundance; but what to do with it? Can a _theory_ be made out? I sit and reflect.
