Sir WALTER SCOTT, alias THE GREAT UNKNOWN, alias BILL BEACON, alias CUNNING WALTER, underwent a long private examination, on a sort of novel fraud, which was whispered to be one of a very extensive nature; nothing transpired after the examination, and the prisoner was ordered up for a further hearing. Sir W. S. being a Baronet, and one of the Bench being a Scotchman, the prisoner was allowed to be out on his own recognizance. He is a tall farmer-looking man — something of a Northern Cobbett. He is said to he the same person that was connected with the Longman gang in the great poetical robbery — and that obtained the King's pardon, by turning King's evidence against his companions.
