Mrs. Anderton had not been long under his care when the remonstrances of several friends led to the cessation of the Baron's immediate manipulations, the mesmeric fluid being now conveyed to the patient through the intervention of a third party. Mademoiselle Rosalie, "the medium" thus employed, was a young person regularly retained by Baron R** for that purpose, and of her it is necessary here to say a few words. She appears to have been about the age of Mrs. Anderton, though looking perhaps a little older than her years; slight in figure, with dark hair and eyes, and in all respects but one answering precisely to the description of that lady's lost sister. The single difference alluded to, that of wide and clumsy feet, is amply accounted for by the nature of her former avocation. She had been for several years a tight-rope dancer, &c., in the employ of a travelling-circus proprietor; who, by his own account, had purchased her for a trifling sum, of a gang of gipsies at Lewes, just at the very time when the younger Miss Boleton was stolen at Hastings by a gang whose course was tracked through Lewes to the westward. Of him she was again purchased by the Baron, who appears, even at the outset, to have exercised a singular power over her, the fascination of his glance falling on her whilst engaged upon the stage, having compelled her to stop short in the performance of her part. There can, I think, be little doubt that this girl Rosalie was in fact the lost sister of Mrs. Anderton, and of this we shall find that the Baron R** very shortly became cognisant. It does not appear that on the first meeting of the sisters he had any idea of the relationship between them. He was, indeed, perfectly ignorant of the early history of both. The extraordinary sympathy therefore which immediately manifested itself between them was not improbably set down by him as a mere result of the mesmeric _rapport_, and it was not till he had been for some weeks in attendance on Mrs. Anderton that accident led him to divine its true origin. Nor, on the other hand, does this singular sympathy--a sympathy manifested in a precisely similar manner to that known to have existed years ago between the sisters--appear to have raised any suspicion of the truth in the mind of either Mrs. Anderton or her husband. From the former, indeed, all mention of her early life had been carefully kept till she had probably almost, if not entirely, forgotten the event, while the latter merely remembered it as a tale which had long since ceased to possess any present interest.
