It was a November night of the year 184-. For a week past the play-bills, upon the convenient but unsightly posts that disfigure the boulevards, had announced for that evening, in conspicuous capitals, the first performance of a new opera by a popular composer. Although the season of winter gaieties had scarcely begun, and country-houses and bathing-places retained a portion of the fashionable population of Paris, yet a string of elegant carriages, more or less coroneted, extended down the Rue Lepelletier, and deposited a distinguished audience at the door of the Académie de Musique. The curtain fell upon the first act; and a triple round of applause, of which a little was attributable to the merits of the opera, and a good deal to the parchment palms of a well-drilled _claque_, proclaimed the composer's triumph and the opera's success, when two men, entering the house at opposite sides, met near its centre, exchanged a familiar greeting, and seated themselves in contiguous stalls. Both belonged to the class which the lower orders of Parisians figuratively designate as _gants jaunes_; the said lower orders conscientiously believing primrose gloves to be a covering as inseparable from a dandy's fingers as the natural epidermis. The younger of these two men, the Viscount Arthur de Mellay, was a most unexceptionable specimen of those _lions dorés_ who, in modern French society, have replaced the _merveilleux_, the _roués_, and _raffinés_ of former days. Sleek of face and red of lip, with confident eye and trim mustache, his "getting up" was evidently the result of deep reflection on the part of the most tasteful of tailors and scrupulous of valets. From his varnished boot-heel to the topmost wave of his glossy and luxuriant _chevelure_, the severest critic of the mode would in vain have sought an imperfection. Born, bred, and polished in the genial atmosphere of the noble faubourg, he was a credit to his club, the admiration of the vulgar, the pet of a circle of exclusive and aristocratic dames, whose approving verdict is fashionable fame. His neighbour in the stalls, some years older than himself, was scarcely less correct in externals, although bearing his leonine honours much more carelessly. Like Arthur, he was a very handsome man, but his pale face and fair mustache contrasted with the florid cheek and dark hair of his companion. The Austrian baron Ernest von Steinfeld had acquired, by long and frequent residences in Paris, rights to Parisian naturalisation. He had first visited the French capital in a diplomatic capacity, and, after abandoning that career, had spent a part of every year there as regularly as any native _habitué_ of the Club Grammont, the Chantilly race-course, and the Bois de Boulogne. Although a German and a baron, he was neither coarse, nor stupid, nor smoky. He did not carry a tobacco-pipe in his pocket, or get muddled at dinner, or spit upon the floor, or participate in any other of the nastinesses common
