The most showy and best defined type of the demi-monde is the adventuress, who is the popular representative of the entire class. The French playwrights have delineated her fully, and made her familiar to everybody. “Camille,” and “The Marble Heart,” have heroines of this sort. The former drama treats her sentimentally, and the latter cynically. She is not so generous and self-sacrificing as Camille, nor so selfish and sordid as Marco. After Alexandre Dumas wrote “Camille,” and achieved such astonishing success, another Parisian _littérateur_ composed “The Marble Heart” as an offset to it, declaring Marco to be the real, instead of the ideal lorette. [Sidenote: TRUE STORY OF CAMILLE.] The story of “Camille,” or “La Dame aux Camelias,” as it is termed in the original, is founded very largely on fact. The central figure of Dumas’ pathetic drama had genuine existence. Her name was Marie Duplessis. She was as lovely in person and as elegant in manner as she is portrayed on the stage. Indeed, the theatric picture was almost a photograph, and the incidents of Marie’s life have been closely followed. The Armand was a young and excessively romantic physician, who, having met the beautiful cocotte at an opera ball, fell so desperately in love with her that he wished to make her his wife. She had too much good sense and prudence, independent of feeling, to permit such a sacrifice; but his devotion and generosity touched her nearly, and soon awoke an answering passion. In spite of her errors, she seems to have been intrinsically a fine and noble woman, who, under favorable circumstances, might have been pure and true. So much was she impressed by his chivalry that she cast off her admirers, purchased a handsome villa near Versailles, and begged her new lover to share it with her. He did so; for he was infatuated with Marie, and would not listen to the sober counsels of his family and friends. His father, in very moderate circumstances, was sorely troubled at the conduct of his son, who had no thought nor care for anything but his mistress. The old gentleman, unable to influence the head-strong boy, sought an interview with the lady of the camellias, and begged her to break off the connection. She undertook the task, and succeeded where his family had failed. Her success, however, was obtained at the expense of truth and her own heart; for she made her lover believe that her attachment to him was waning.
