The revelations not long since published in the London _Pall Mall Gazette_ revealed fashionable aristocratic depravity in the British metropolis in a shamefully disreputable light, and disclosed the services of the professional procuress in all their repulsive loathsomeness. Although we do not possess titled libertines at elegant leisure here, there can be no manner of doubt that the procuress plies her vocation among us, and thrives on a liberally perennial patronage. Whatever may be her characteristics in other respects, she is invariably an elegantly-dressed woman, with persuasive address, suave speech and attractive mien. In most cases procuresses possess houses of their own, where they procure desirable ladies for their patrons. Sometimes these establishments are termed "Introducing houses," and, as may be imagined, are exceedingly lucrative to their proprietors. Sometimes ladies are boarded and lodged in the house; but they are usually "independent," or, in other words, living under the protection of some patron of the establishment. Some of these procuresses possess a list of ladies whom they can send a messenger for on demand. Take the case of a well-known establishment in one of the most fashionable quarters up-town, for example: A wealthy broker, speculator, or attache of Uncle Sam, calls upon the lady of the house at a fashionable afternoon hour, orders wine, and enters into conversation about indifferent matters, until he is able delicately to broach the subject he has in view. He explains that he wishes to meet with a quiet lady, whose secrecy he can rely upon, and whom he can trust in every possible way. He intimates his preference for an elegantly-formed, young and fairly good-looking acquaintance, and would like her, in addition, to be vivacious, witty and a little gay. The lady of the house listens complacently, and replies that she is acquainted with a lady who will suit him to a nicety, and offers to send a message for her at once, if he wishes; but he must take his chance of her being at home. Should she be out, she intimates an appointment will be made for next day. In the meantime, a messenger is dispatched to the lady in question, and more wine is ordered and drank. When the lady arrives, the introduction takes place, and the business is transacted, as far as the procuress is concerned. Sometimes the gentleman pays the professional fee, and sometimes the lady gives half the money she receives from the patron to the madame of the house.
