A mistake was made yesterday, by an unfortunate suitor in
the Court of Requests, similar to those illusions which, from the days of Pesunts to the present, when people go to laugh at WRENCH iu My Twin Brother, have furnished writers f'or the stage with their most amusing subjects. Mr. JoNEs, a surgeon, summoned Mr. KLAUS SCHNACKENBURGER, a German of course, for non-payment of a small bill for medicine and attendance. The defeudant swore that he had never seen Mr. " lanes" in his life before. Mr. JONES declared that he had attended Jilin for upwards of a week, and knew him perfectly well; his assistant gave evidence to the same effect; and therefore the Commissioner, in spite of sundry oaths sworn in very good German by Mr. SCHNACKENBURGER, decided that be must pay the money. The matter had proceeded thus far, when, in answer to a call from the defendant, another person entered, and stood beside him. One was the exact counterpart to the other—" like in all parts as one egg to another." The defendant maliciously asked Mr. JONES, if he would adhere to the statement he had made upon oath ? but Mr. JONES was now too much puzzled to swear to his patient. It appeared from a further examination by the Commis.sioner, that both the Germans bore the name of Kr. MIS SCIINACKENBURGER, and both lived at " Numbro dice, Yorge Street." They are cousins: and find their exact resemblance to each other very useful on occasions like the present.
