A knock at the door was heard, and in a few moments there entered a visitor, with the easy familiarity of intimate acquaintance--a young man, but with none of the bloom of youth. His hair, fine as a woman's, was thin and scanty, but it fell low over the forehead, and concealed that noblest of our human features. "A gentleman," says Apuleius, "ought, if he can, to wear his whole mind on his forehead."[15] The young visitor would never have committed so frank an imprudence. His cheek was pale, and in his step and his movements there was a languor that spoke of fatigued nerves or delicate health. But the light of the eye and the tone of the voice were those of a mental temperament controlling the bodily--vigorous and energetic. For the rest his general appearance was distinguished by a refinement alike intellectual and social. Once seen, you would not easily forget him. And the reader no doubt already recognizes Randal Leslie. His salutation, as I before said, was that of intimate familiarity; yet it was given and replied to with that unreserved openness which denotes the absence of a more tender sentiment. Seating himself by the Marchesa's side, Randal began first to converse on the fashionable topics and gossip of the day; but it was observable, that, while he extracted from her the current anecdote and scandal of the great world, neither anecdote nor scandal did he communicate in return. Randal Leslie had already learned the art not to commit himself, not to have quoted against him one ill-natured remark upon the eminent. Nothing more injures the man who would rise beyond the fame of the _salons_, than to be considered a backbiter and gossip; "yet it is always useful," thought Randal Leslie, "to know the foibles--the small social and private springs by which the great are moved. Critical occasions may arise in which such knowledge may be power." And hence, perhaps (besides a more private motive, soon to be perceived), Randal did not consider his time thrown away in cultivating Madame di Negra's friendship. For despite much that was whispered against her, she had succeeded in dispelling the coldness with which she had at first been received in the London circles. Her beauty, her grace, and her high birth, had raised her into fashion, and the homage of men of the first station, while it perhaps injured her reputation as woman, added to her celebrity as fine lady. So much do we cold English, prudes though we be, forgive to the foreigner what we avenge on the native. Sliding at last from these general topics into very well-bred and elegant personal compliment, and reciting various eulogies, which Lord this the Duke of that had passed on the Marchesa's charms, Randal laid his hand on hers, with the license of admitted friendship, and said--
