At the close of her first song, the enthusiasm of the highly respectable and very numerous assemblage seemed to know no bounds. It burst forth with an unappeasable _furor_, resulting in the reappearance of the songstress, who seated herself at the piano forte, and sang, to her own somewhat simple accompaniment, a slow air, in a full, round bass voice, that would have been envied by old Meredith himself--who used to sit under London bridge of a foggy morning, that he might catch a cold, and sing "deeper and deeper still." Her tones probably reached down to G. as represented by the open third string of the violoncello. No male voice could have given utterance to sounds more clearly and strikingly masculine; and people gazed in wonder, as though dubious of the sex of the performer--a doubt that was soon dispelled by the smooth sweetness of the next vocal piece from Norma, and by the astonishing height to which the "Swan" ascended, in surmounting and mastering the brilliant and beautiful cantata, "Like the Gloom of Night retiring."--The Swan is of good figure and form, with a full bust, containing organs more completely adapted to the development of the vocal powers and qualities, than those of any other human being, whose voice we ever listened to, or tested. Her age is apparently about twenty-five; her complexion not exactly ebony, but approaching it as nearly as the brownest black can possibly do; her features, but slightly modified from the pure African lineaments--retaining the low forehead, the depressed nose, and the expansive mouth, without the bulbous labia. As the lady reader is anxious on the subject of dress, we will say that her principal exterior garment enclosed the whole person excepting the caput; whether composed of printed de laine, or French chintz, we could not examine--but the colour of its ground, as near as the gas-lights allowed us to determine, was either light blue, or green-cerulean or emerald, rather profusely covered with large white flowery figures; her gloves were of white kid, from which depended a fine nine shilling linen handkerchief. She wore what appeared to be heavy gold ear-rings; and her hair, jet black, with the natural wiry curl, was arranged _a la_ Jenny Lind. Her manner and carriage were exceedingly easy, and even graceful. The voice of this sable phenomenon possesses most extraordinary properties. Its compass and elasticity are immense, and its tone will bear favourable comparison with that of most, if not all the public vocalists of the day. She has evidently cultivated but little of the ornamental portion of the art--giving us few or no shakes, nor any chromatic flights, though occasionally a respectable cadenza.
