In the steamship City of Brussels, from New York, on the 2d of May, 1871, arrived a cargo which, in the words of Mr. Toole, may be termed “most extraordinary.” Of all the curiosities ever unearthed by the immortal Barnum, none can compare in the most minute degree with Millie Christine, a daughter or daughters--whichever the fastidious please--of the State of North Carolina. They first saw the light nineteen years ago, and the mother is presumably the founder of that gigantic Woman’s Rights Association in America, which has lately made formidable inroads upon English society. Here we have a young lady with one body, but two distinct minds, borne by two separate heads. All the intelligent men who saw her at the Washington Hotel the other day, can bear witness to the marvellous intelligence which predominates in both brains; the conversational powers of the two heads at once in communication with two different persons; upon different topics, would sufficiently testify it. But the marvel did not stop here; some of the sweetest duets in the language of music were sung by a high soprano and a pure contralto. The notes issued from two heads, and yet but one trunk supplied the _verve_. It may now be added that this extraordinary trunk has two pairs of perfect legs, terminating in symmetrical and very pretty feet, and that, moving upon their pedal extremities, the trunk exhibits the very poetry of motion. The polka, the mazourka, the schottische, are delineated by these two pairs of pretty feet, in perfect time and harmony, and the spectator is rewarded not by one smile, as in the case of ordinary young ladies, but by two distinct smiles, winked at you by two pairs of sparkling and roguish eyes, and thrown at you by two different sets of the purest ivory that ever adorned the mouth of an Indian Sultana. There are a lot of people here, or elsewhere, always ready to strain at the smallest gnat and swallow the biggest camel, who will doubtless put this young lady down as outside the pale of ordinary humanity. If this prejudice should carry one so far as to avoid her, they alone will be the losers. We can testify that no person of ordinary intelligence can be in her company for half an hour without yielding to the charm of her manner and the fascination of her double smiles. She has you on both sides. If you remove your head from one position you are immediately the victim of another pair of eyes, which fix you and, in fact, transfix you. We candidly admit that we were fascinated, and that we immediately lost sight of the phenomenon and became overpowered by the influence of this dual brain. The young lady will shortly hold _levees_ in London, and the public of Liverpool may hope to see her by-and-by. The eminent medical men of the United States testify that this remarkable freak of nature is united at the lateral posterior portion of the pelvis, while above that portion they are separated, have separate chests,
